The specific embodiment

Below with reference to Fig. 1-4 show the example that is used to pack and smear the assembly 10 of fluid product of the present invention, this fluid product is used to prevent hair loss.This assembly 10 has container 20, has one at the top of container and smears head 30.

This container is with the thermoplastic material rigid bottle form that constitutes of PET for example.Replacedly, glass bottle also can use.This bottle for example has the capacity of 6ml.This bottle has longitudinal axis X and comprises non-symmetrical side walls 21, is sealed by bottom 22 in an end of this side walls 21.This bottom 22 for example is the concave wall that is used for easily locating thumb.The second end of this bottle ends at free edge 23, and this free edge 23 defines an opening 24.

Be fastened on this bottle in order to smear head 30, this bottle has screw thread 25 on its outer surface, and this screw thread 25 is near free edges 23, this screw thread 25 be used for be arranged on the inside face of smearing head on complementary threads cooperate.

Between screw thread 25 and free edge 23, the outside face of this bottle has striped 26, and the function of this striped 26 will be set forth below, and this striped 26 is parallel to an X and extends.This striped 26 can be only extends on the part of the outer rim of bottle, for example extends on two axial opposed annular sections of bottle.Replacedly bottle can have striped on its whole outer rim.

Bottle also has cannelure 27, and groove 27 is formed between position 26 and the screw thread 25, cannelure 27 as following diaphragm 40 can being fastened on the bottle of seeing.

This smears the neck that head 30 is used to be fastened to bottle.For this purpose, this is smeared head and has the clamp flange 31 that is provided with screw thread 32 on interior periphery, and screw thread 32 is used for cooperating with the screw thread 25 of bottle.Replacedly, regulation is smeared head by on the fastening neck that is fixed on bottle of clamping.

In the top of flange 31, the radially shoulder 33 of flange 31 is provided with and is used for the seal ring 34 that diaphragm 30 is placed on no leak ground, shown in Fig. 3 B.

In this shoulder outside, clamp flange extends jet pipe 35, and this jet pipe 35 defines an inner passage 35a, and at the free end of jet pipe, this passage 35a leads to the spout 36 that distributes goods.This jet pipe is to be formed on this edge smearing head with respect to axle X accentric mode.Select inner passage 35a, particularly inner passage 35a to make according to the viscosity of goods and can prevent that the by gravity goods flow out simply.

This clamp flange 31 is also sealed by convex wall 37 at an upper portion thereof.This convex wall 37 can be out of shape when the direction that is parallel to an X is exerted pressure, thereby can press convex wall 37 towards this inside of smearing head.This distortion can make the tensile surface fracture of the goods in the applying head portion, thereby allows goods to distributing spray orifice 36 to flow.

Smear head 30 and also have the turned parts 38 of the following diaphragm 40 that is used to rupture, this diaphragm 40 seals opening 24 in the mode of no leak before using bottle.Turned parts is a blade 38, and it is parallel to an X and extends as far as the free edge 39 towards bottle.These blade 38 slight curving feasible only partial arcs are according to the profile of clamp flange 31.As shown in Figure 3A, to be bevelled be inserted in the diaphragm 40 being convenient to the free edge 39 of this blade.Free edge 39 is also treated the plane inclination of the diaphragm of fracture mutually, as shown in Figure 7, so that assembly contacts this diaphragm.According to the distortion shown in Fig. 8, this free edge 39 has two tilt components with different inclined-planes, the second little parts 39b of ratio first parts inclination that is used to begin to cut the roughly bevelled first parts 39a of diaphragm and is used for cutting fully.

In order to limit the size of this assembly, produce enough big deformable wall simultaneously, this blade 38 forms the extending axially in the part of a wall of jet pipe.So also be easy to the demoulding of jet pipe.

Screw thread

25 and 32 preferably has shallow inclined-plane so that further improve cutting, thereby makes that smearing head need carry out being tightened into house more than once rotation when head is tightened onto on the bottle when smearing.This diaphragm is cutting gradually therefore, and be sure of to cut fully so that make bottle opening freedom.

Smear head preferably by with one-piece parts molded acquisition.Smearing head can make with the integrated thermoplastic material, particularly polyethylene, polypropylene, poly-para Toluic Acid's glycol ester, and polyvinylchloride, polyamide is made.Replacedly, convex wall 37 can on be molded on the remainder of smearing head, for example smear head elastomeric material, particularly rubber, for example Santoprene  makes.In both of these case, obtained to wash smear head can repeated use so that smear head.

According to the distortion shown in Fig. 5, can replace convex wall 37 with bellows 137.

Smear head fixing on before, bottle is sealed by diaphragm 40, this diaphragm 40 by thermoplastic material for example PET constitute.This diaphragm clamping is fastened on the neck of bottle.Replacedly, this diaphragm 40 can be tightened onto on the bottle.

Form diaphragm 40 with circular wall 41, circular wall 41 comprises the weakening region 42 that is used to cut.This weakening region 42 extends along a circle, and it is neighbouring so that almost whole bottle opening 24 can be freely that this circle preferably is positioned at the outer rim of this diaphragm.This weakening region 42 can form with the circular portion of wall 41, and the thickness of the circular portion of this wall 41 is littler than the remainder of wall.Replace having less thickness along this whole circle, this weakening region can have variable thickness, and this thickness particularly can change by sawtooth form.Along repeatedly changing thickness between two values of this circle: corresponding to first value of the thickness of wall 41 and the second less value.

In the outside of the part 42 with low thickness, this circular wall 41 is extended with clamp flange 43, and this flange 43 extends axially and has annular bead 44 on the surface within it, and this annular bead 44 is used for being contained in the groove 27 of bottle.This clamp flange 43 also has striped (not shown in the accompanying drawings) on inside face, these stripeds are used for cooperating with the striped 26 of bottle.This has constituted anti-rotation device, and this anti-rotation device can limit diaphragm and rotatablely move on bottle.Certainly, any other the coarse form that can satisfy this rotation-prevention function except striped can be arranged on diaphragm and/bottle on.Replaceable or additionally, the inside diameter of this clamp flange can be selected according to the outer dia of bottle, so that the clamping to diaphragm 40 defines rotatablely moving of the relative bottle of diaphragm on bottle.

The sealing flange 45 concentric with clamp flange also is arranged on the diaphragm, and sealing flange 45 extends axially between low thickness area 42 and clamp flange 43 from circular wall 41, with end lip type thing 46 extend the same far away.This flange leans against on the inside face of bottle in the mode of anti-leak.This lip type thing 46 is easy to when being fastened on the bottle with convenient diaphragm sealing flange 45 is inserted the neck of bottle and centering in the neck of bottle along the direction slight inclination at the center of this flange.Such shape is particularly by preventing that stacking each other of diaphragm also is easy to distribute diaphragm on manufacturing line.End lip type thing 46 is continuous in the example of Fig. 2.According to a distortion shown in Fig. 6, with the end lip type thing that lappet 47 forms, this lappet 47 makes and can obtain more pliable and tougher lip type thing.

This diaphragm 40 by obtaining with the thermoplastic material single piece is molded, is particularly used polyethylene similarly, polypropylene, poly-para Toluic Acid's glycol ester, polyvinyl chloride, polyamide.This diaphragm can be made with integral material, and perhaps replacedly, this circular wall 41 can be made with the double injection elastomeric material.

According to a kind of distortion (not shown), this smears that head 30 can not be tightened onto bottle but on the diaphragm 40, this diaphragm has screw thread on its exterior wall then.As further distortion, this is smeared head 30 and can clamping be fastened on the bottle.

In order to use this device, the user holds bottle 20, and this bottle 20 is sealed by diaphragm 40.The user will smear head 30 and be fixed on the bottle, be tightened onto this bottle of sealing on the neck by smearing head 30.One side screws one side owing to have striped on diaphragm, and the relative bottle of this diaphragm is maintained fixed, and like this by being formed on the friction force on the striped 26 on the bottle, prevents that the relative bottle of this diaphragm from doing any rotatablely moving.One side screws, and blade 38 one sides cooperate with the circular portion 42 of the diaphragm with low thickness gradually, as shown in Figure 3A, and till this part fracture.This dispense spout is communicated with bottle interior then.When screwing end, the circular wall 41 of diaphragm can separate and drop in the bottle fully, shown in Fig. 3 B.Replaceable, this circular wall 41 can be kept being connected with diaphragm by little radial component.

The user can smear this product by the scalp of being inverted this device and make jet pipe point to the user then.As shown in Figure 4, for example the user with thumb as on the container bottom and its forefinger be placed on and grip applicator on the convex wall.The user causes the output goods by the extruding convex wall then, so that output products.Stop to push the outflow that is enough to stop goods for the user.Therefore the user has ideally controlled the output of goods.The assembly of Huo Deing is to meet very much human engineering like this, and its less shape is suitable for using with two fingers, thereby very easy to use.Because the diameter of spout is less and be positioned at the jet pipe end, so goods also flow on people's the head in the mode of height local positioning, this makes can smear this goods by very big degree of control.

After the inclusion of smearing this bottle, the user can outward winding from the bottle of sky and smear head 30 so that reuse it later on.In fact, this smears head can be used for another bottle once more using for the first time with it under the identical condition, has preferably cleaned and has used after smearing head.
