- the toothbrush 10 comprises a portion with a hollow handle 11, which outputs a portion to shaft 12, which carries at the other end of the handle a sole bristle carrier 13, provided on one side of the bristle tufts 14.
- the hollow handle 11 made for example of plastic, is shaped as a small bottle and is consistuée by two semi-shells, one forming a bottom 11.2 11.4 11.3 and the other of which outputs a collar 11.1.
- the said semi-shells 11.2, 11.3 are necessarily coupled to each other.
- the hollow handle 11 has a practically square cross section with rounded angles.
- a bag reservoir with a flexible elastic wall in the form of a small valley 15 is inserted, for example rubber latex, showing a tubular mouth 15.1 inserted coaxially in the said neck 1 1.1 of the handle and counted out by a fairly thick integral annular edge 15.2 applied as a tight elastic seal against the free bottle of the neck 11.1 itself.
- the tank-shaped elastic balloon 15 is filled with pressure by a fluid-paste-like preparation such as a gel, iusq 'to have its wall by elastic expansion in contact with the inner surface of the handle hollow 11.
- the rod 12 is made, for example, of plastic material and it constitutes a separate part of the handle 11 and it is grafted by force coupling on the neck. 11.1 of the handle even by one of its ends 12.1 which has been made hollow, so as to be constantly supported and fluid-tight, by this annular-joined edge 15 ⁇ 2, relative to the handle itself.
- a small conical tube 12.2 integral, which is inserted in a sealed manner in this mouth 15.1 of the elastic balloon reservoir 15. coaxial with the neck 11.1 and putting the fluid in communication with the tank itself. It should be noted that this small tube (funnel) 12.2 is inserted into the mouth 15.1 counteracting the action of the elastic valve retaining elements 16 (which will be said later on) which would otherwise keep the mouth closed even when fluid is retained.
- a small rectilinear rod 17.1 for example made of plastic, located and guided by sliding in a corresponding guide guide with longitudinal channel 12.4, provided in the rod 12 and exit in the small well 13.1 practically at the level of the slot 13.2, elements with elastic pad 18, for example of rubber latex, are interposed between a longitudinal end 17.2 of the rod 17.1 next to the handle 11 and the semi-shell 11.3 of the handle itself and they act elastically on the rod itself, by urging in the longitudinal direction towards the free end of the head 13. In this way, the other longitudinal end 17.3 of the small rod 17.1 is normally maintained (FIG. 1) elastically extended relative to the guide 12.4 in order to intercept and ostruct this slot 13.2 to waterproof and blocking the communication of the small well 13.1 with the outside.
- elements with elastic pad 18, for example of rubber latex are interposed between a longitudinal end 17.2 of the rod 17.1 next to the handle 11 and the semi-shell 11.3 of the handle itself and they act elastically on the rod itself, by urging in the longitudinal direction towards the free end of the head 13.
- Sub 17.4 is indicates an integral grip relief, provided at this end 17.2 with the small rod 17.1 for manual removal of the same rod (according to the arrow effe in FIG. 2) in opposition to the elastic action of the cushion elements 18 of so as to withdraw in correspondence the other bottle 17.3 of the rod with reference to the slot 13.2 to allow free communication of the small well 13.1 with the outside.
- Sub 11.6 are indicated with relief guide elements 17.4, integral to the semi-shell 11.3
- the handle 11, the elastic pad 18 and the relief 17.4 of the rod 17.1 are co-formed and arranged anatomically and ergonomically, for facilitate grip and maneuver in a convenient and natural way with one hand by the user who grabs at 11 the toothbrush 10.
- Sub 19 ( Figure 1) is indicates a removable protective cap, for example plastic, installed by seuvegerde of the head 13 and the rod 12 of the toothbrush 10 and partially intesti on the reservoir 11 of the same.
- the cap (19) is provided with boreholes not shown.
- the balloon reservoir 15 is inserted into the semi-shell 13.3 in coaxial arrangement through its tubular neck 11.1 so that its annular edge - joint 15.2 is established against the free end of the neck 11.1, its mouth 15.1 is disposed in the cervix itself and the prestante part of the body with elastic-flexible wall partially leaves the cervix towards the interior of the semicoquille itself (figure 4).
- the semi-shells 11.2 and 11.3 are therefore forcibly coupled and will form the hollow handle 11, which incorporates the empty elastic balloon reservoir 5 (FIG. 5).
- these elastic valve elements 16 comprise , inside the mouth 15.1, an arrangement of six internal integral reliefs 16.1, by way of small bumps flanked in the round and stretched in rays towards the interior having the relative points in contact:
- the filling pressure of the reservoir balloon 15 continues until its flexible wall with elastic expansion either length or width, do not occupy the entire cavity of the handle 11 ( Figure 6).
- the air hole 11.5 ensures the relative output of air from the handle 11.
- the reservoir balloon 15 is lubricated on the outside, for example by application of sylicone. and the correspondents, and the relative plastic parts of the handle 11 are waxed
- the cannula C of the filling element is extracted from the mouth 15.1 of the reservoir 15 and the internal leak-tightness 16.2 is self-contained in elastic-tightness thus preventing the exit of the toothpaste gel , otherwise biased to come out outside the elastic retraction force of the balloon tank 15 ( Figure 7).
- the rod 12 is therefore forcibly grafted onto the neck 11.1 of the handle 11 by making a strong sealed connection via the joint edge 15.2 of the reservoir 15.
- the elastic pad 18 is thus interposed between the end 17.2 / 17.4 of the small sliding rod 17.1 and the semi-shell 11.3 of the handle 11.
- the toothbrush 10 can, therefore, be used in a traditional way for hygiene and cleaning of waste and then be put back, ready for another use.
- a single wire 141 made of plastic is provided with a single wire 141 made of plastic, to form stamping integral body with the small head 131 even partially notch and longitudinally, during removal from the mold, up to the free end, so as to form a small open fork at the top.
- This arrangement while it makes it possible to reduce production costs remarkably, because it avoids the suffocation of the small head 131, has the advantage of great hygienic security, care, once the tufts of bristles have been eliminated, l he accumulation is reduced at the base of the notched threads 141 of poisoning substances and the like.
- sub 200 a dispenser for fluid-pasty substance is indicated, which comprises a rigid envelope 11. made for example of plastic material and shaped like a small bottle.
- the envelope 11 is constituted by two semi-shells, one 11.2 forming a bottom (not illustrated) and the other 11.3 from which a neck 11.1 emerges. These semi-shells 11.2 - 11.3 are coupled together by force.
- the bottom is formed a hole for air.
- Dan the rigid casing 11 a bag container which is inserted in the flexible-resilient wall as the balloon 15, for example rubber latex, which has a tubolar 15.1 mouth inserted on the axis in collar 11.1 of the envelope outside an integral annular edge 15.2. assetz thick and applied as a tight elastic seal against the free end of the neck 11.1 itself.
- a cup body 210 On semicoquille 11.3 of said casing 11 a cup body 210 is seated stably, reversed and provided inside of an integral cap 211; which invests in waterproofing. by means of the gasket 15.2 the neck 11.1 of the envelope 11. From the inside of the cap 211 outputs a short tapered tube 212. complete. which is inserted leaktight in the mouth 15.1 of the elastic balloon reservoir 15, on the axis of the neck 11.1 and in fluid communication with the reservoir itself.
- this tube 212 communicates with the outside of the reservoir 15 through a hole passing 213 on the axis of the bottom 210.111 of the cup body 210.
- this bottom 210.1 of the body 210 is superimposed on a rotating element with discs 214 around a pivot 210.2 integral at the very bottom.
- This disc element 214 is the object concentrically in an annular wall 210.3 protruding from the outer round edge of the bottom 210.1.
- lever 215 extends in radius from the disc element 214 through a slot with a circoference arc 215.1, placed in this external annular wall
- An elastic return cushion 216 for example made of natural rubber, is interposed between this lever wall 215 of the disc element 214 and a corresponding fixed internal relief 210.4, stretched in radius towards the inside of the external annular wall 210.3, so as to normally bias elastically the element disk 214 in a determined position of autur tour 210.2 pivot up to the end of travel, called thereafter rest position, illustrated in solid lines in Figure 17.
- An elastic penstock 210.5 is partly housed in a corresponding groove in the internal circumference of the external annular wall 210.3 and it is applied against the disc element 214, so as to keep the latter stably against the base
- a through hole 217 is placed eccentrically in said disc element 214 and on said hole 217 in the discs 214 is stably grafted coaxially a rigid cannula element, so as to form a small dispensing spout.
- the arrangement of the parties is such that. in said rotated rest position of the disc element 214, the through hole 213 placed in the bottom 210.1 of the cup body 210 and the small dispensing spout 218 do not correspond axially, such that the fluid-pasty substance does not can not come out of the tank 15.
- either the toothbrush 10 or the dispenser 200 comprise an accumulated energy motor element, constituted by the elastic bag reservoir 15, which uses the elastic potential energy accumulated by filling with a fluid-pasty substance in order to give the substance itself, under control by the user, so as to dispense the energy accumulated as the substance itself comes out respectively between the bristles of the toothbrush 10 or the small dispenser nozzle 200.
- the user has control elements (17; 214; 215) for the output flow through the distribution elements (13; 13.1; 13.2; 217; 218) which allow him to dose the given pasty-fluid substance according to need.
- check valve elements 16 automatically obstruct the mouth of the reservoir 15, as soon as the fluid-pasty substance is filled, before mounting in the toothbrush 10 or in the dispenser 300. This simplifies and remarkably facilitates the operations. of manufacturing.
- this reservoir 15 is automatically maintained in fluid communication with the elements for distributing the fluid substance. pasty through intercommunication elements (12.2; 212). which eugagent in opening these check valve elements 16.
- the small head 13 of the toothbrush can be coated with a rubber sheath, adherent and provided on the outside with integral bristles, so as to avoid the traditional suffocation of the small head itself.
- the bag reservoir can be made of any elastic, natural or syntethical material, for example natural rubber, elastomers, sylicone and the like.
- the check valve elements can also be produced as a separate part of the bag reservoir and be arranged in the fluid passages between the reservoir and distribution elements.
- the bristles of the small head can be produced by simple threads integral with the small head itself and notched longidudinally at least partially, to form tufts open at the top.
