Preferred embodiment describes in detail

With reference to Fig. 1, the disposable toothbrush 10 of first embodiment according to the invention comprises a brush that has the longitudinal extension of a brush holder 14, totally by numeral 12 expressions.This brush holder 14 is made by a kind of for example polypropylene or cinnamic one-tenth ridged plastics.Brush holder 14 comprises first chamber 16 that a certain amount of dental floss is housed and second chamber 18 that a certain amount of collutory is housed.The removable end cap 20 of a flexibility is used to enclosed cavity 18.

See figures.1.and.2, brush 12 comprise one with 14 one-tenth integrally formed base portions 22 of brush holder, use and the brush holder identical materials is made.Base portion 22 has the outer surface 26 of fixing a large amount of bristles 24, and bristle 24 is arranged to be substantially perpendicular to surface 26.Base portion 22 also limits a chamber 28 with substrate 30.Protuberance with wedge angle flange 32 forms is to extend and become whole with it from substrate 30 to form.Hole 34 is passed brush 12 and is extended out, but chamber 28 and bristle 24 earthings are linked together.This brush 12 also comprises a cover of plunger 36, and it is to be made by the flexible material of for example low density polyethylene (LDPE) or preferred thermoplastic elastomer (TPE) and so on.Cover of plunger 36 limits a reserve chamber 38, and it has opening 40.The film of boring a hole 42 that opening 40 is made by a plastic sheeting or sheet metal is hermetically enclosed.A certain amount of toothpaste (shown in pointing with the finger or gesticulate among the figure) is included in 38 li of reserve chamber, in film 42 back.Lid 36 also comprises peripheral protuberance 44, and it is meshed with first and

second protuberances

46 and 48 on the madial wall 49 of base portion 22 atriums 28.This protuberance 44 also is arranged to form sealing with the madial wall 49 in chamber 28.

With reference to Fig. 3, lid 36 is compressed into base portion 22, is meshed with first protuberance 46 on the sidewall 49 of base portion 22 with the protuberance 44 of toilet cover 36, thereby lid 36 is locked on the base portion 22.Lid 36 is in the first inoperative position now, and toothbrush 10 can be sold or be stored at any time.Film 42 guarantees that toothpaste can or not become dry by germ contamination yet to deposit toothpaste (shown in pointing with the finger or gesticulate among the figure) and isolated from atmosphere.

With reference to Fig. 4, in use friction top 36, resemble a plunger, from shown in Figure 3 first active position not, with respect to brush 12, are laterally moved to second active position shown in Figure 4.In the transverse movement process, this wedge angle flange 32 is bored a hole on film 42, and toothpaste (shown in pointing with the finger or gesticulate among the figure) is forced on the bristle 24 through via hole 34.Peripheral protuberance 44 and the engagement of madial wall 49 sealings are overflowed between lid 36 and madial wall 49 to stop toothpaste.Flexible cover 36 has guaranteed also that when lid is depressed most of toothpaste (shown in pointing with the finger or gesticulate among the figure) is forced out reserve chamber.So toothbrush just can be used by the user, this moment, toothpaste was on bristle.After having brushed, the user can clean his/her mouth with collutory, uses dental floss 48 further to clear up tooth then.In case to second active position, lid on 36 peripheral protuberance 44 just and second protuberance 48 on the base portion 22 mesh, locking cover 36 on the spot, so that toothbrush can only use once.

With reference to Fig. 5, according to second embodiment of invention, toothpaste (among the figure strokes and dots shown in) is included in 50 li of pouches that cover 36 li.With reference to Fig. 6, pouch 50 is made by a plastic sheeting or sheet metal, according to the scope moulding of 36 li reserve chamber 38 of lid.Refer again to Fig. 5, in this embodiment, protuberance 32 shown in Figure 1 is replaced by piece 52, and it is to form with 22 one-tenth integral body of base portion of brush 12.This piece has filled up the chamber 28 of 22 li of base portions substantially, supports that spike portion 54 is whole thereupon to be formed.

With reference to Fig. 7, at active position not, the same manner is stuck on the base portion 22 among lid 36 usefulness Fig. 3.Toothpaste that pouch is 50 li and isolated from atmosphere can or not become dry by germ contamination yet.

With reference to Fig. 8, in use, the lid 36 from shown in Fig. 7 not active position laterally be pressed onto active position shown in Fig. 8 with respect to brush 12.In this transverse movement, spike portion 54 bores a hole on the film of pouch 50, and toothpaste (shown in the strokes and dots) just is pressed onto on the bristle 24 by hole 34.And the same with the toothbrush shown in Fig. 4, lid 36 is highlighted portion's 48 locks in place then.Piece 52 has filled up the chamber 28 of base portion 22 substantially in this embodiment, can be pressed onto on the bristle 24 from cover 36 li chamber 38 to guarantee toothpaste as much as possible.Should be noted that flexible cover 36 is being out of shape to guarantee that toothpaste as much as possible is forced on the bristle 24 above the spike portion 54.

Can use a pouch in the toothbrush shown in Figure 1; A lid that has sealing film can use for toothbrush shown in Figure 2.

Toothbrush provides a compactness and the maneuverable head toothbrushes that comprises toothpaste dispenser according to the present invention, and the traveller can make and be discarded after a single use.In addition, this device is a health, and since toothpaste in transportation and storage process, hold with isolated from atmosphere and can not become dry before use.
