Cavity 240 includes vertical section B and vertical section C.Its size and shape of section B of cavity 240 is formed as receiving the housing 301 of allotter 300, and its size and shape of section C of cavity 240 is formed as receiving the distally distribution end 303 of applicator 309 and allotter 300.More specifically, section B has cross-sectional profiles and Xray films, and they are corresponding generally to cross-sectional profiles and the Xray films of the part being nested in cavity 240 of the housing 301 of allotter 300.Similarly, section C has cross-sectional profiles and Xray films, and they are corresponding generally to cross-sectional profiles and the Xray films of the distally distribution end 303 being nested in cavity 240 of the housing 301 of applicator 309 and allotter 300.Certainly, the present invention is not limited to this kind of correspondence in all embodiments.

With continued reference to Fig. 6, Fig. 7 A and Fig. 7 B, cavity 240 has the most tapered cross section for the most of longitudinal length including the cavity of section A and section B, wherein, this cross section along with its forward/move towards the far-end 213 of handle portion 210 away from opening 215 and reduce.In docking or storing state, the tapered cross section of cavity 240 helps routes distribution device 300 and makes allotter 300 be centered to appropriate location to be placed in cavity 240.The cross-sectional area that the cross-sectional area of section C is preferably significantly less than section B is consistent with the respective tapered shape with allotter 300.As best shown in figure 6, in one embodiment the plane of opening 215 preferably about longitudinal axis degree angled transversally to help further to remove allotter and by allotter again insertable into cavity 240 from cavity 240.

With continued reference to Fig. 6, Fig. 7 A and Fig. 7 B, the inwall 241 of cavity 240 includes circular ridge 242, this circular ridge 242 be designed in order to when being in storing state with the annular groove 304 of allotter 300 fluidly mating.Circular ridge 242 and groove 304 provide for allotter 300 is fastened on locking system in the handle portion 210 of toothbrush 200 removedly.In a possible embodiment, circular ridge 242 is preferably protrusion shape on cross section and groove 304 can have the recessed cross section of complementation to promote smoothing but the joint (seeing Fig. 6 and Fig. 7 A) of locking between convex ridge and groove.Certainly, other matched shape and/or feature can be also used on allotter 300 and wall 241, replace the groove/ridge arrangement for being fastened on removedly in the handle portion 210 of toothbrush 200 by allotter 300.Circular ridge 242 can form the transition part between the section B and section C of cavity 240 as shown.

With continued reference to Fig. 6, Fig. 7 A and Fig. 7 B, the inwall 241 of cavity 240 also can farther include annular shoulder 243, and this shoulder 243 is preferably placed near the far-end 213 of handle portion 210 as shown.Annular shoulder 243 provides the prominent structure of the less distally cross-sectional area producing section C near the far-end 213 of handle portion 210 with the form of applicator end bearing (receptacle) 400.Although annular shoulder 243 is shown as rectangle corner or edge, but it can use various shape and cross section profile or profile, including angled edge, bending radius or arcuate edge etc..Annular shoulder 243 is configured to and is suitable to engage mutually the distally distribution end 303 of allotter 300 when allotter 300 is completely inserted in cavity 240.This provide the retainer for allotter 300 housing 301 distribution end 303 in case prevent cavity inner wall 241 the most front laterally/vertical being excessively inserting and contacting between distal end wall 401 and the free end of applicator 309, this free end may result in oral cavity nursing agent and from allotter " drainage " or leaks into cavity, this confusion that can produce oral cavity nursing agent and loss.Therefore, annular shoulder 243 preferably produces little spacing (seeing Fig. 7 B) between the distal end wall 401 of the free end of applicator 309 and cavity 241.Bearing 400 further preferably constructs and is formed as with size in order to applicator 309 to be received in wherein and can be substantially consistent with the shapes and sizes of applicator, provides applicable circumferential spacing between also to prevent lateral joint the between applicator and end bearing 400 from preventing leakage simultaneously.Certainly, in some embodiments of the invention, annular shoulder can omit, and wherein cavity 241 and allotter 300 are preferably for being configured so that when allotter 300 fully disposes and is docked in the cavity 241 of toothbrush 200 handle portion 210 to keep between the distal end wall 401 of the end of applicator 309 and cavity little spacing mutually.Annular shoulder 243 and the structure with allotter 300 thereof cooperate and will be described in greater detail below.

Referring also to Fig. 7 A and Fig. 7 B now, will be explained in greater detail the structure cooperation between allotter 300 and toothbrush 200 in storing state.As it can be seen, oral care systems 100 is in storing state.When being in storing state, allotter 300 is slidably located in the cavity 240 of toothbrush 200 handle 210 as shown.Most of length of allotter 300 is nested in the cavity 240 of toothbrush, and more preferably allotter 300 at least 75% length be nested in the cavity 240 of toothbrush 200.

When being in docking or storing state, the circular ridge 242 of the annular groove 304 of allotter 300 receiving cavity 240 inwall 241 matchingly, thus allotter 300 is not fixedly secured on its position.The coupling of groove 304 and convex ridge 242 makes allotter fastening in place, until user applies enough power to overcome the coupling reciprocal action between groove 304 and convex ridge 242, thus is removed to use from toothbrush 200 by allotter 300.Needed for overcoming coupling to engage, shear force will be controlled by respective size and the tolerance of groove 304 and convex ridge 242 really.

The elastic outer layer 307 of allotter also promotes that the free-standing between allotter 300 and toothbrush 200 fastens, because outer layer 307 is by the convex ridge 242 of inwall 241 and/or compressing of other parts.Additionally, the compression of elastic outer layer 307 adds the size of power needed for the CONTACT WITH FRICTION overcome between the outer surface 305 of inwall 241 and allotter 300 housing 301.

Coupling between groove 304 and convex ridge 242 also performs another function, namely coupling reciprocal action forms gas-tight seal between the outer surface 305 of wall 242 and allotter 300.This kind of gas-tight seal prevents water and may damage other fluid entrance cavity 240 of the integrity of applicator 309 and/or the behavior of oral cavity nursing agent.The compression of elastic outer layer 307 also enhances this kind of effect.Except when allotter stops water and other unnecessary fluid to enter outside cavity 240 when being in storing state, gas-tight seal also prevents applicator from becoming dry during non-use periods.

When being in docking or storing state, annular shoulder 243 additionally aids to play and maintains integrity and the oral cavity nursing agent of applicator 309 during non-use periods and/or utilize toothbrush 200 to carry out the effect scrubbed.More specifically, when being in storing state, annular shoulder 243 contacts the outer surface 305 of (and compression slightly) housing 301, thus forms the second gas-tight seal and/or barrier being isolated by the section C of internal cavity and the section B of cavity 240.Therefore, storing state exists two gas-tight seals from external environment condition of protection section C and applicator 309.Certainly, can use only one or another.And, gas-tight seal is formed also by only contact between the outer surface 305 and inwall 241 of allotter 300.

The gas-tight seal formed by annular shoulder be may be particularly helpful for preventing leakage that applicator 309 is unnecessary and/or is dried, because can obtain little free volume in the section C of cavity 240.In other embodiments, allotter 300 not can be fixedly secured in the cavity 240 of toothbrush 200 by compressed fit only between allotter and inwall 241 and/or f pictional surface contacts.

Referring now to Fig. 8, according to the alternative that present invention show allotter 300A.In addition to distribution end 303A is suitable to have and is fastened to cap 330A thereon and is made up of homogenous material layer 306A, the allotter 300 in allotter 300A with Fig. 4 and Fig. 5 is identical.In order to avoid redundancy, eliminate the detailed description to those components roughly the same with allotter 100 in allotter 300A.But, for the sake of reference and understanding, label identical in addition to adding letter suffix " A " is for identifying identical part.

Distribution end 303A of the housing 301A of allotter 300A includes the surface character (groove 315A form ringwise) for mating with corresponding construction (convex ridge 331A form ringwise).Cap 330A is not fixedly secured to housing 301A by mating between the annular groove 215A and circular ridge 331A of cap 330A of housing 301A, thus encapsulates applicator 309A to prevent spilling and/or becoming dry of activating agent.Although groove/convex ridge matching component is illustrated as being held in place cap 330A, but may be used without other surface character and the structure that can engage with matching each other and/or cooperate.The structures and methods that cap is attached to tubular body are well known in the art.

The housing 301A of allotter 300A is also monolayer 306A structure.The material of monolayer 306A should provide the necessary rigidity of structure compatible with oral cavity nursing agent.

Referring now to Fig. 9, it is shown that be specifically designed to receive the toothbrush 200A on it with the allotter 300A maintaining cap 330A.In addition to internal cavity 240A is shaped differently and has the allotter 300A of cap 330A for storage, the toothbrush 200 in toothbrush 200A and Fig. 1-7B is identical.In order to avoid redundancy, eliminate the detailed description to those components roughly the same with toothbrush 200 in toothbrush 200A.But, for the sake of reference and understanding, label identical in addition to adding letter suffix " A " is for identifying identical part.

The internal cavity 240A of toothbrush 200A has features designed to receive the section C of the cap 330A of allotter 300A.Due to cavity 240A storage allotter 300 and attached cap 330A thereof, therefore it is not required in wall 241A constitute shoulder, because cap 330A forms the second gas-tight seal for applicator 309A.Allotter 300A (having cap 330A) is shown as in Fig. 10 and is in storage location in toothbrush 200A.
