- The present invention is directed to a toothbrush which also comprises a toothpaste dispenser, thereby diminishing the space required for storing a toothbrush and the toothpaste thereof.
- The toothbrush according to preferred embodiments of the present invention comprises two major parts: a toothbrush assembly and a toothpaste dispenser.
- According to embodiments of the invention, the toothpaste dispenser is embedded within the construction of the toothbrush assembly, such that dimensions of the toothbrush assembly are not significantly increased, thereby maintaining the common form of a toothbrush although it also comprises a toothpaste dispenser.
-
FIG. 1 is a pictorial view which schematically illustrates a toothbrush according to one embodiment of the invention, from one viewpoint. -
FIG. 2 is a pictorial view which schematically illustrates a toothbrush according to one embodiment of the invention, from another viewpoint - Although
toothbrush 2 comprises a toothpaste container, the size thereof corresponds to a common size of a toothbrush, therefore being disposable after using several times. For example, assuming a user uses 1 cc for a tooth brushing “session”, a quantity of 5 cc will be adequate for 5 times. Preferably, the volume of the toothpaste container has to be between 3 to 10 cc, which may correspond to 3 to 10 tooth brushing sessions. - In order to dispense toothpaste from the toothpaste dispenser, a user must turn switch 14 to its “open” state, and press
surface 6 with his thumb. Preferably, the paste is poured out at the bottom ofbristles 8. - After use, the user turns switch 14 to its “closed” state, in order to protect the remaining toothpaste stored in the container from contact with the air, thereby preventing undesirable drying.
-
Surface 6 is also referred to herein as “squeezer”. -
FIG. 3 is a longitudinal cross-section of a toothbrush which schematically illustrates its structure, according to one embodiment of the invention. -
FIG. 4 is a cross-section which schematically illustrates a toothpaste dispensing operation, according to one embodiment of the invention. - The dispenser assembly comprises a
toothpaste container 20 embedded withinhandle 4 of the toothbrush assembly, and apassageway 22, connected at one end thereof tocontainer 20. The paste is dispensed through the other end ofpassageway 22, which is deployed betweenbristles 8 of the toothbrush assembly. -
Squeezer 6 is a part of the walls of the toothpaste container. According to one embodiment of the invention, the squeezer is deployed on the outer surface of the toothbrush, and therefore is available to contact by a user. Squeezing the container by pressing onsqueezer 6 with a thumb results in diminishing the volume ofcontainer 20, and as a result, the toothpaste stored within the container exits viaoutlet 16, which according to the examples herein is deployed betweenbristles 8. - The space enclosed within
toothpaste container 20 and thetoothpaste passageway 22 is a closed space. One of the objects of the invention is preventing contact between the air and the closed space, thereby preventing drying of the stored toothpaste. -
Squeezer 6 may be made of deformable material, in order to prevent its returning to the initial form, thereby preventing the toothpaste from falling back. - Of course, more complicated mechanisms may be used for squeezing the toothpaste container, but the present mechanism is characterized by simplicity, and as a result the manufacturing effort is decreased.
- As illustrated,
switch 14 is connected to aslider 15 which operates as a closure totoothpaste outlet 16.FIGS. 5 and 6 schematically illustrate the structure and operation of a closure, according to one embodiment of the invention.FIG. 5 schematically illustrates the open state ofclosure 15, andFIG. 6 schematically illustrates the closed state thereof. - According to this example, the closure comprises two states, “open” and “closed”. In the “open” state,
passageway 22 is open, and in the “closed” state,passageway 22 is closed. As illustrated, in the open state, opening 32 of the slider coincides with the opening ofoutlet 16, and in the closed state, opening 32 of the slider does not coincide with the opening ofoutlet 16. -
FIGS. 7 and 8 schematically illustrate the structure and operation of a closure, according to another embodiment of the invention.FIG. 7 schematically illustrates the closed state ofclosure 15, andFIG. 8 schematically illustrates the open state thereof. - According to this embodiment, a
spring 19returns slider 15 to its “idle” state. Thus, upon pressingsqueezer 6, the toothpaste pushesslider 15 to the open state of the closure, thereby enabling the toothpaste to be pushed out of the container. Upon releasingsqueezer 6,spring 19returns slider 15 to its closed state. - It should be noted that according to this embodiment of the invention, the
manual switch 14 is eliminated, since opening and closingclosure 15 results from pressing and releasing (correspondingly)squeezer 6. - The advantage of this embodiment of the closure is that the user need not
open closure 15 manually, since this operation is carried out automatically. - In addition, according to this embodiment of the invention, there is no need of a
valve 18 to prevent the toothpaste from falling back. -
Valve 18 is illustrated inFIGS. 3 and 4 , and detailed inFIGS. 9 and 10 . - The object of
valve 18 is to prevent the paste stored withinpassageway 22 from falling back whensqueezer 6 is released, in the case wherein the squeezer is made of flexible material. However, ifsqueezer 6 is made of deformable material, which does not return to its original shape upon releasing, the valve may be omitted. Thus,valve 18 operates as a no-return mechanism for the dispensed paste. -
FIGS. 9 and 10 schematically illustrate a valve, according to one embodiment of the invention. -
Numeral 44 denotes an opening, through which paste passes, and numeral 42 denotes a flexible lid for opening 44. When paste is pushed “upwards” (with regard to the illustration),lid 42 bends, allowing the paste to pass throughopening 44. When paste is pushed “downwards”,lid 42 seals opening 44, thereby prevents paste passage throughopening 44. -
FIG. 11 schematically illustrates the closed state of a valve, according to one embodiment of the invention.FIG. 12 schematically illustrates the open state of the valve ofFIG. 11 . - According to this embodiment of the invention, a
valve 12 is deployed at theoutlet 16. In this way, the valve performs both the operation of a no-return mechanism, and the operation of a closure. - The tooth brush according to the present invention is mostly useful while traveling, camping, and so forth. Its manufacturing is relatively easy due to the minor number of parts it consists of. Its dimensions doesn't exceed from the dimensions of a “common” toothbrush. As a result of its minor number of parts it can be used as a one-time apparatus, or a disposable apparatus.
