Definitions
- the field of the present invention relates generally to dental care products, particularly those which are designed to be disposable. More specifically, the present invention relates to disposable toothbrushes having disposable brush portions that attach to specially configured handles.
- a common problem for most people is the lack of availability of a toothbrush when it is desired to brush one's teeth. Although it is relatively simple to brush the teeth early in the morning and at night when one is at the home and the washroom is available, it is much more difficult to brush one's teeth after meals that take place away from the home (as is typical for lunch). This problem is exasperated when a person is traveling. As such, most people go extended periods of time during the day when they do not brush their teeth. Besides the increased likelihood of tooth decay and gum diseases, the inability to have a toothbrush handy leads to people being self conscience about possible food particles remaining on their teeth and a desire to freshen the breath. Both of these problems can be resolved by carrying a toothbrush with a person so that it can be used when desired. Unfortunately, this is not a very suitable alternative for most people due to the problems with trying to carry around a toothbrush (such as keeping it clean and surrounding surfaces dry).
- the toothbrush In order for the person to effectively clean his or her teeth, the toothbrush must contain a bristle portion that are designed to clean the teeth, reach into the areas between teeth and provide a massaging action for the gums. Toothbrush bristle design has evolved over the years to utilize materials and bristle placement that have been found to be more effective at removing food and other contaminants from the teeth. However, it is well known that repeated use of a toothbrush results in a wearing down of the individual bristles or a reshaping of the bristle pattern (i.e., flaying the bristles). This process is normal and inevitable for all toothbrushes. As a result, in order to maintain the effectiveness of the tooth brushing process, it is highly recommended by the dental profession that people replace their toothbrushes on a regular basis so as to maintain the desired effectiveness of the toothbrush bristles.
- the toothbrush can be responsible for the transmission of diseases if the toothbrush is used by another person or comes into contact with another person's toothbrush. Even if not, the contaminated toothbrush can make it very difficult for a person to fight an existing mouth disease due to the likelihood of retransmission of the disease back to the person through the toothbrush. Even though this result can be avoided by the daily replacement of the toothbrush or by extraordinary sterilization processes, the cost of doing so makes either of these alternatives economically infeasible for most persons.

Description
- 1. Field of the Invention
- The field of the present invention relates generally to dental care products, particularly those which are designed to be disposable. More specifically, the present invention relates to disposable toothbrushes having disposable brush portions that attach to specially configured handles.
- 2. Background
- The importance of good dental hygiene is well known. Regular use of a toothbrush to brush the teeth and gums is the best and most commonly available means for the average person to prevent tooth decay and various gum diseases. In fact, other than regular visits to the dentist, cleaning one's teeth with a toothbrush is the most practical and effective way to prevent tooth decay and gum disease. It is well known that to be most effective, the teeth should be brushed daily between meals so as to prevent build-up of tooth-decaying substances on and between the teeth. Generally, most people utilize one of the many specially developed and commonly available toothpastes on the toothbrush to improve brushing effectiveness. As part of the brushing process, most people rinse, to one degree or another, the toothpaste and food particles from the toothbrush upon completion of cleaning the teeth and gums. Typically, the toothbrush is shaken to remove some of the rinse and is then placed in a holder or cup to air dry.
- A common problem for most people is the lack of availability of a toothbrush when it is desired to brush one's teeth. Although it is relatively simple to brush the teeth early in the morning and at night when one is at the home and the washroom is available, it is much more difficult to brush one's teeth after meals that take place away from the home (as is typical for lunch). This problem is exasperated when a person is traveling. As such, most people go extended periods of time during the day when they do not brush their teeth. Besides the increased likelihood of tooth decay and gum diseases, the inability to have a toothbrush handy leads to people being self conscience about possible food particles remaining on their teeth and a desire to freshen the breath. Both of these problems can be resolved by carrying a toothbrush with a person so that it can be used when desired. Unfortunately, this is not a very suitable alternative for most people due to the problems with trying to carry around a toothbrush (such as keeping it clean and surrounding surfaces dry).
- In order for the person to effectively clean his or her teeth, the toothbrush must contain a bristle portion that are designed to clean the teeth, reach into the areas between teeth and provide a massaging action for the gums. Toothbrush bristle design has evolved over the years to utilize materials and bristle placement that have been found to be more effective at removing food and other contaminants from the teeth. However, it is well known that repeated use of a toothbrush results in a wearing down of the individual bristles or a reshaping of the bristle pattern (i.e., flaying the bristles). This process is normal and inevitable for all toothbrushes. As a result, in order to maintain the effectiveness of the tooth brushing process, it is highly recommended by the dental profession that people replace their toothbrushes on a regular basis so as to maintain the desired effectiveness of the toothbrush bristles.
- Another problem with toothbrushes, which is alleviated to some extent by the replacement of the toothbrush on a regular basis, is that they tend to be breeding grounds for numerous pathogenic organisms that are known to be able to thrive in the bristles of a toothbrush. Food particles, saliva, bacteria, toothpaste and other materials are known to accumulate on the toothbrush. In addition, various mouth viruses and other diseases can also accumulate in the toothbrush bristles. The fact that most tooth brushing and toothbrush storage takes place in the bathroom, which is known for disease transmission and is generally a warm and moist environment, only makes the build-up of pathogenic organisms more likely. The mere rinsing of the toothbrush under running water, which is what is done by most people, does not remove these materials from the bristles to an extent sufficient to render the toothbrush free of the pathogenic organisms. As a result, the toothbrush can be responsible for the transmission of diseases if the toothbrush is used by another person or comes into contact with another person's toothbrush. Even if not, the contaminated toothbrush can make it very difficult for a person to fight an existing mouth disease due to the likelihood of retransmission of the disease back to the person through the toothbrush. Even though this result can be avoided by the daily replacement of the toothbrush or by extraordinary sterilization processes, the cost of doing so makes either of these alternatives economically infeasible for most persons.
- Prior art disposable toothbrushes have not been well received by the general public. Typically, this is because the prior art toothbrushes are difficult to use, expensive to replace and/or bulky in design. It can be appreciated, therefore, that what is needed is a disposable toothbrush that is suitable for effectively cleaning a person's teeth and which is of a type that allows the person to easily dispose of the toothbrush. To have a realistic chance of being accepted by most people, the disposable toothbrush must be economical to buy and use, therefore requiring the toothbrush to be made out of materials that are inexpensive to produce. The preferred disposable toothbrush should be easy to use and be of a design which is suitable for both adults and children.
- The disposable toothbrush of the present invention solves the problems and provides the benefits identified above. That is to say, the present invention is directed towards an improved disposable toothbrush that is inexpensive to make, easy to use and effective at reducing or preventing the spread of diseases of the teeth, gums and mouth and improving the immunity system. In the preferred embodiment of the present invention, the disposable toothbrush has head member that removably connects to an elongated handle member to form a toothbrush for brushing teeth and gums. The handle member has a an attachment portion at the front end, a handle portion at the opposing back end and a pair of opposing sides. The opposing sides of the attachment portion are disposed apart an attachment width amount and the opposing sides of the handle portion, rearward of the attachment portion, are disposed apart a handle width amount. The head member has a base portion having a top side and an opposing bottom side and a first end and an opposing second end. A plurality of bristles, grouped together in tufts, extend outwardly from the bottom side of the base portion to form the brush portion. To attach the head member to the handle member, a pocket is disposed on the top side of the base portion. The pocket has an open end at the first end of the base portion, a closed end at the second end of the base portion and an interior passage extending substantially to the second end of the base portion. To maintain the head member to handle member connection during brushing, the interior passage of the pocket is sized to securely receive the attachment portion of the handle member.
- The handle portion of the toothbrush is sized and configured to be ergonomically comfortable in the user's hand. Typically, this will result in the attachment portion of the handle member having a greater width than the handle portion. To facilitate the disposable nature of the present invention, the base member can be made out of a paper material, such as cardboard that is treated to make it water resistant. In addition, the opposing pocket sides of the pocket can have one or more pocket ridges that are designed to interact with the one or more handle ridges on the attachment portion of the handle member. The pocket and handle ridges should be sized and configured to engage each other so as to secure the head member to the handle member. If a more secure connection is desired, the head member and the handle member can include a locking mechanism for locking the head member to the handle member.
- The improved disposable toothbrush of the present invention will reduce the spread of infectious diseases, including but not limited to diseases of the mouth, teeth and gums, by eliminating a prevalent but not so well known source of germs and bacteria. The present invention will allow people to brush their teeth more often, as recommended by dentists and dental organizations, without requiring the carrying of standard toothbrushes. As is well know, if a person is to carry a standard toothbrush with them, they must also carry a device or container for preventing the toothbrush from picking up contaminants and adding those contaminants to the already fertile breeding ground of the typical toothbrush.
- Accordingly, the primary objective of the present invention is to provide a disposable toothbrush having the features generally described above and more specifically described below in the detailed description. It is also an important objective of the present invention to provide a disposable toothbrush that includes a head member made out of a paper material, such as cardboard, having a plurality of bristles extending outwardly from the head member. It is also an important objective of the present invention to provide a disposable toothbrush that securely but removably attaches a head member having a brush portion to a handle member. The above and other objectives of the present invention will be explained in greater detail by reference to the attached figures and the description of the preferred embodiment which follows.

- With reference to the figures where like elements have been given like numerical designations to facilitate the reader's understanding of the present invention, and particularly with reference to the embodiments of the present invention illustrated in FIGS. 1 through 5, the preferred embodiments of the present invention, designated generally as10, are set forth below.
Disposable toothbrush 10, shown as a single unit in FIG. 1, generally has ahandle member 12 and ahead member 14. Thedisposable toothbrush 10 of the present invention helps prevent the spread of germs by facilitating the disposal of the portion of thetoothbrush 10 that is most susceptible to contamination and the transmission of diseases, which is thehead member 14. Although the primary embodiment of thepresent invention 10 envisions the disposal of thehead member 14 only, it should be understood that theentire toothbrush 10, including thehandle member 12, can be made to be disposable. -
Handle member 12 has afront end 16, an opposingback end 18 and opposingsides 20, as best shown in FIG. 2. In the preferred embodiment of thepresent invention 10,handle member 12 is made out of a plastic that is both rigid and flexible, as is known in the art, to facilitate brushing of one's teeth withtoothbrush 10. As is well known, the typical toothbrush handle is stiff enough to apply pressure to the teeth and gums, yet flexible enough that is has some give so as to avoid injury (particularly to the gum area). At thefront end 16 ofhandle member 12, the opposingsides 20 are disposed apart a distance referred to herein as the attachment width, shown as 22 on FIG. 2, to form anattachment portion 24. Rearward of theattachment portion 24, the opposingsides 20 are disposed apart a distance referred to herein as the handle width, shown as 26 on FIG. 2, to form ahandle portion 28. As set forth below, theattachment portion 24 interacts with thehead member 14 to form a one-piece toothbrush 10.Handle portion 28 should be sized and configured to be ergonomically comfortable in the user's hand. As is known in the art, various shapes and configurations forhandle portion 28 can be utilized. As explained in more detail below, the combined effect of having anergonomic handle portion 28 and the need to securely attachhead member 14 to handlemember 12 will result in the preferred embodiment of thepresent invention 10 having anattachment width 22 that is greater than thehandle width 26. - As best shown in FIGS. 3 through 5,
head member 14 has abase portion 30 having afirst end 32 and an opposingsecond end 34 and a top side 36 and an opposingbottom side 38.Base portion 30 can be of any preferred shape, although it will typically be rectangular, square or oval in shape. In the preferred embodiment, because thehead member 14 is designed to be thrown away after use,base portion 30 is made out of a paper material, such as cardboard, that is biodegradable. The paper material should be strong enough to support the plurality ofbristles 40 that extend downwardly from thebottom surface 38 ofbase portion 30 to formbrush portion 42 when thetoothbrush 10 is in use. However, because thetoothbrush 10 of the present invention is preferably designed to be a single use item, thebase portion 30 does not have to be configured to withstand the rigors of multiple uses and prolonged exposure to water or the humid environment of the typical bathroom. If desired, the cardboard forbase portion 30 can be treated or coated with a variety of known materials to reduce the penetration of water or other fluids intobase portion 30 so as to further strengthenhead member 14. Thebristles 40 can be of the size, configuration and type commonly utilized for toothbrushes. As is commonly done, thebristles 40 can be grouped together into a plurality of tufts. Various configurations of bristle patterns for thebrush portion 42 are also well known in the art. - To connect the
head member 14 to handlemember 12, the present invention utilizes apocket 44 disposed on the top side 36 ofbase portion 30, as shown in FIGS. 3 through 5. In the preferred embodiment, thepocket 44 has anopen end 46 at thefirst end 32 ofbase portion 30, aclosed end 48 at thesecond end 34 ofbase portion 30 and aninterior passage 50 between theopen end 46 andclosed end 48, extending substantially from thefirst end 32 to thesecond end 34 ofbase portion 30. Theinterior passage 50 ofpocket 44 should be designed and configured to securely receive theattachment portion 24 ofhandle member 12 therein. In this embodiment, theattachment width 22 should be approximately equal to the width ofinterior passage 50 so that thepocket 44 is securely attached toattachment portion 24. Theattachment portion 24 should be able to slide insideinterior passage 50 so thathead member 14 is frictionally held ontohandle member 12. - To more securely attach
head member 14 to handlemember 12, the present invention can include one ormore pocket ridges 52 on theinsides 54 ofpocket 44 forminginterior passage 50, as shown in FIG. 6. To provide an even more secure connection betweenhead member 14 and handlemember 12, thesides 20 ofattachment portion 24 can comprise one ormore handle ridges 56 that are sized and configured to engage thepocket ridges 52 insideinterior passage 50. Theridges head member 14 and handlemember 12. The use of theseridges head member 14 onhandle member 12. If an even more secure connection is desired, such as fordisposable toothbrushes 10 sized and intended for children or for use with person's who have diminished mental capacity, then a locking mechanism can be used to lockhead member 14 ontohandle member 12 during the brushing process. Any such locking mechanism should be designed to releasehead member 14 fromhandle member 12 once brushing is complete and disposal ofhead member 14 is desired. One such locking mechanism, shown in FIG. 7, can comprise asnap lock 58 onhandle member 12 that interacts with alip 60 onhead member 14. These types of locking mechanisms are common. They function by slidinghead member 14 ontoattachment portion 24 untillip 60 is forced under thesnap lock 58 or by pulling thesnap lock 58 back to allowlip 60 to pass undersnap lock 58. Thesnap lock 58 closes overlip 60locking head member 14 ontoattachment portion 24. When brushing is complete, thehead member 14 is removed fromhandle member 12 by utilizing the thumb or finger to pullsnap lock 58 open so thatlip 60 can pass back undersnap lock 58 and thehead member 14 removed. - An example configuration for the
disposable toothbrush 10 of the present invention is set forth below. The example is meant to be exemplary only and not to limit the invention in any way. As an example, thehandle portion 28 can be 6-½″ long and ½ wide and theattachment portion 24 can be ¾ long and ¾″ wide. The overall length ofhandle member 12 with these dimensions would be 7-¼″. Thehead member 14 could be 1″ long by 1″ wide having four rows of eleven tufts each protruding from thebottom side 38 approximately 1-¼″. Thepocket 44 would be ¾″ wide by ¾″ long. Whenhead member 14 is secured ontohandle member 12, the overall length oftoothbrush 10 would be 7-½inches. A child size version of thetoothbrush 10 could have ahandle portion 28 that is ⅜″ wide by 5-½″ long having anattachment portion 24 that is ½″ long by ½″ wide. Thehead member 14 would be ¾″ wide by ¾″ long and would have apocket 44 that is ½″ wide by ½″ long. Thesmaller head member 14 could utilize three rows of seven tufts each protruding from thebottom side 38 approximately 1″. - In use, the
toothbrush 10 of the present invention will be typically provided in two parts, one being thehandle member 12 and the other being one ormore head members 14. Generally, a plurality ofhead members 14 will be provided in a bag or sack. To ensure thehead members 14 remain clean until needed, they can be individually wrapped inside the bag or sack. When brushing is desired, the person would remove one of thehead members 14 from the bag or sack and remove the wrapping material. Typically, thehead member 14 would be gripped on its sides and slide onto theattachment portion 24 ofhandle member 12. In the preferred embodiment, thehead member 14 would frictionally secure itself to theattachment portion 24. If a locking mechanism is utilized, it would be operated to allow thehead member 14 to be placed on thehandle member 12. Once the brushing is complete, the user would pullhead member 14 off of the attachment portion, disengaging the locking mechanism if necessary, and dispose of thehead member 14 in the trash. If desired, the individual wrapping forhead members 14 can be of the type that is resealable (i.e., such as many sandwich bags) so the usedhead member 14 can be placed back in the wrapping for disposal. Also, if desired, the attachment portion of thehandle member 12 can dipped or wiped with alcohol to sterilize it. As set forth in more detail above, the use ofdisposable toothbrush 10 eliminates the build-up of contaminants on thebrush portion 42 and substantially reduces the likelihood of spread of diseases. - If a completely
disposable toothbrush 10 is desired, thehandle member 12 can also be made out of a paper material, such as the same cardboard used forhead member 14. Naturally, anysuch handle member 12 would have to be made sufficiently stiff so that it can be used to brush the teeth without collapsing or breaking. In this manner, the user would simply throw away theentire toothbrush 10 when finished brushing his or her teeth. - While there is shown and described herein certain specific alternative forms of the invention, it will be readily apparent to those skilled in the art that the invention is not so limited, but is susceptible to various modifications and rearrangements in design and materials without departing from the spirit and scope of the invention. In particular, it should be noted that the present invention is subject to modification with regard to the dimensional relationships set forth herein and modifications in assembly, materials, size, shape, and use. The present invention resides in the novel features of form, construction, mode of operation and combination of elements presently described and understood by the claims.
