Definitions
- the present invention relates to a fluid dispenser comprising a flexible pocket of variable volume having an opening, a pocket support having a fixing surface at which the opening of the flexible pocket is fixed, and a dispensing member such as 'a pump or a valve, mounted on the pocket support to be able to take fluid product through the opening of the flexible pocket.
- a fluid dispenser such as can be found in the field of cosmetics, perfumery or even pharmacy.
- Flexible bags are generally used to protect the fluid product from the ambient air and thus avoid any deterioration of the fluid product by oxidation or drying.
- the user presses on the pusher of the dispensing member, which has the effect of delivering a dose of fluid which is taken from the flexible bag by the pump or the valve.
- To prevent the fluid product from coming into contact with the air in the flexible bag it collapses on itself by reducing its volume as fluid product is extracted from it by the pump or the valve.
- the flexible bag is fixed, often by welding, to the bag support on which the pump or the valve is mounted.
- the pocket support therefore forms a fixing appendage which often has a diamond or eye shape.
- the fixing surfaces by welding of the fixing appendage are constituted by the external walls of a cylinder, not circular, but in the shape of a diamond or an eye.
- the pocket is generally formed from two flexible sheets welded together on their peripheries, except at the opening, so that the opening is formed by an area which is not welded together of the two sheets.
- the two sheets constituting the pocket are in contact with one another and the opening is closed in a leaktight manner.
- This kind of flexible pocket is advantageous for dispensers having an elongated vertical shape.
- the flexible bag to have a certain capacity, must be sufficiently long, since between its filled and empty state, its height does not vary much.
- the present invention aims to remedy this drawback of the prior art by defining a fluid dispenser whose flexible bag is particularly well suited to be used in a jar-shaped dispenser.
- a fluid dispenser comprising: - a deformable flexible pocket of variable capacity provided with an opening, - a flexible pocket support on which the opening of the flexible pocket is fixed, said support comprising a fixing surface at which the flexible bag is fixed from the support, - a dispensing member, such as a pump or a valve, mounted on the pocket support for withdrawing fluid from the pocket, characterized in that said fixing surface is substantially planar, so that it extends in one plane.
- the fixing surface is annular.
- the support comprises a substantially tubular sleeve having a longitudinal axis, the dispensing member extending in this sleeve, the plane of the fixing surface being perpendicular to said longitudinal axis.
- the fixing surface is formed by one face of a flat annular flat flange disposed in the pocket around its opening.
- the flexible pocket comprises two flexible sheets welded together on their periphery along a weld line, the opening of the flexible pocket being located on one of the sheets.
- the opening is located substantially in the center of one of the sheets.
- the weld line of the two sheets extends in a plane substantially parallel to that of the attachment surface of the pocket support.
- the empty flexible bag has an almost zero thickness in the direction of the longitudinal axis.
- the present invention also defines a method for manufacturing a flexible bag provided with a flexible bag support, said method comprising the steps of:
- the support is used to cut the opening of the sheet, advantageously by punching.
- FIG. 1 is a view in vertical transverse section through a fluid dispenser according to the invention
- - Figures 2 to 4 are schematic views of the various stages of manufacture of a fluid product bag provided with a bag support according to the invention.
- the fluid dispenser shown in FIG. 1 comprises a flexible pocket 1, a flexible pocket support 2, a dispensing member 3 and a shell 4.
- the dispensing member 3 is a pump, but it could also have been a valve.
- the pump 3 comprises a pump body 30 defining a lower end 33 forming the inlet and an upper end forming a protruding flange 34.
- the pump 3 comprises an actuating rod 31 which is movable in the body pump 30 along a longitudinal axis A.
- the end of the actuating rod 31 is capped by a pusher 32 which defines a dispensing orifice 35.
- the pusher 32 is here in the form of a cup with the orifice of distribution 35 placed in its center so as to be able to collect the product distributed by the pump. Once the product has been distributed on the pusher 32, the user only has to take it using one or more fingers. It is understood that such a pump 3 is more suitable for the distribution of creams or pasty cosmetic products in general.
- the pump 3 is advantageously a pump without air intake, that is to say that it does not allow the entry of outside air inside the pump as the fluid is distributed.
- the pump 3 is received in a pocket support 2 which comprises a substantially tubular sleeve 22 and an annular flange 21 which extends radially outwards at the lower end of the sleeve 22.
- the interior of the sleeve 22 is hollow and thus forms a through passage 23.
- the sleeve 22 forms a receiving housing, advantageously by snap-fastening, to receive the projecting flange 34 of the pump body 30.
- the pump 3 is thus fixed in the sleeve 22 with the pump body 30 extending in the passage 23.
- the lower end 33 of the pump body 30 which forms the inlet of the pump is advantageously located at the lower end of the sleeve 22, as can be seen in Figure 1.
- the sleeve 22 and the pump 3 have the same longitudinal axis A.
- the sleeve 22 forms one or more anchoring profiles 221 whose function will be given below.
- the flange 21 which extends radially outwards from the lower end of the sleeve 22 has a substantially planar annular fixing surface which extends on one of the faces of the flange 21.
- this planar fixing surface is located on the upper face 212 of the flange 21, that is to say on the face turned towards the sleeve 22.
- this annular fixing surface can be provided with reliefs which do not affect the general planar configuration of the surface. These reliefs can for example serve to improve the quality of the attachment of the pocket.
- the lower face 211 of the flange 21 can also serve as a fixing surface in place of the upper face 212. However, when this lower face 211 does not serve as a fixing surface, it is not necessarily flat and can therefore have a significant relief.
- the lower face 211 is preferably also planar, and the thickness of the flange 21 is preferably relatively small, so that the flange is in the form of a thin flat annular disc pierced in its center by the crossing passage 23.
- the pocket 1 is fixed to the pocket support 2 at the level of the fixing surface, which is here the upper face 212. Since the fixing surface 212 is annular and planar and perpendicular to the longitudinal axis A, the flexible pocket 1 at its opening 121 is arranged flat and perpendicular to the longitudinal axis A. The part of the flexible pocket 1 bordering its opening 121 therefore extends flatly on the flange 21 around the sleeve 22 which projects through the opening 121. The flange 21 is therefore disposed inside the flexible bag 1 while the sleeve 22 extends outwards. Consequently, the passage 23 of the sleeve 22 communicates the interior of the flexible bag through its opening 121 with the pump 3. More specifically, as can be seen in FIG. 1, the inlet 33 of the pump 3 is located at the opening 121 of the bag 1.
- the opening 121 of the pocket 1 is formed in a flexible sheet 12, advantageously at its center.
- This sheet 12 is connected to another sheet 11 along a peripheral connecting line 112. It should be noted that the opening 121 is formed by the single sheet 12 and that the sheet
- the peripheral connecting line 112 common to the two sheets 11 and
- the flexible sheet 11 can come into contact with the underside 211 of the flange 21 so that the thickness of the pocket corresponds to the cumulative thickness of the two flexible sheets 11 and 12 and of the flange 21 which is extremely flat. This is especially true when the flexible sheets are flat. Consequently, the thickness of the bag 1 in the empty state in the direction of the axis A, can be of the order of 1 to 3 mm.
- this flexible pouch 1 is particularly well suited for use in dispensers of fluid which are in the form of a jar and not a bottle.
- dispensers of fluid which are in the form of a jar and not a bottle.
- the dispenser also comprises a shell 4 which comprises an outer casing 40 of cylindrical shape in FIG. 1.
- the outer shape of the shell 40 can be very varied depending on the aesthetic appearance that one wishes to give to the dispenser .
- it is a distributor in the form of a pot, so that the external envelope 40 is not very high with respect to its diameter to give it the appearance of a pot.
- the outer casing 40 extends to the level of the pusher 32 of the pump 3 which can advantageously move inside the casing 40.
- the casing 40 can be provided with a bottom (not shown).
- AT the interior of the envelope 40 extends an annular plate 41 which is here substantially planar. We could also have formed this plate 41 with other shapes, for example frustoconical.
- This tray 41 extends inward and defines in its center a hole 43 in which the sleeve 22 of the pocket support 2 extends.
- the latter is formed with retaining means 42 which cooperate with the anchoring profiles 221 formed near the upper end of the sleeve 22.
- These retaining means 42 may for example be in the form of a tapered slotted socket which allows a certain deformation elastic towards the outside to allow the passage of the anchor profiles 221 at the upper end of the bush 42.
- the engagement of the anchor profiles 221 at the upper end of the bush 42 corresponds with the setting support of the flange 21 under the plate 41 at the edge of the hole 43.
- the pocket 1 is fixed at the upper face of the flange 21, it is the pocket 1 which comes into contact pressed against the face bottom of tray 41. From this fact, the edge of the opening 121 of the flexible bag 1 is wedged between the flange 21 and the plate 41.
- the method of fixing by welding to the flange 21 is preferred, it is also envisaged to make a tight fixing of the pocket 1 on the pocket support 2 by simple wedging of the pocket 1 between the flange 21 and the plate 41. In any case, even with fixing by welding, the jamming of the pocket between the flange 21 and the plate 41 can only contribute to improving the fixing and sealing of the bag.
- the frustoconical retaining socket 42 n is not a limiting embodiment.
- the flexible bags fixed to a pocket support are generally made from two sheets welded together on their peripheries except at the opening in which the pocket support is inserted before final welding.
- the manufacture of the pocket is different in that the fixing of the pocket support is carried out before weld the two sheets together. More specifically, we begin by making an opening 121 in a flexible sheet 12. Then insert the sleeve 22 of a pocket support 2 through the opening 121 until the sheet 12 comes into contact with the upper face of fixing 212 of the flange 21. Next, advantageously by welding, the sheet 12 on the flange 21 along a welding line 122.
- a flexible sheet 12 is thus obtained fixed to a pocket support whose sleeve 22 is protruding through the opening 121 and the flange 21 of which is located on the underside of the sheet 12.
- the final step consists in attaching another flexible sheet 11, advantageously of the same dimension as the sheet 12, to the sheet 12 by example by welding, along a peripheral connecting line 112.
- the sheet 11 is welded to the sheet 12 on the side where the flange 21 extends so that the flange 21 is located inside the flexible bag with its sleeve 22 which projects towards the e xtérieur through the opening 121. All these manufacturing steps are shown in Figures 2, 3 and 4.
- the pocket support 2 and more particularly its sleeve 22 to make the opening 121 in the sheet 12.
- the opening 121 can be punched by the pocket support 2 which is then immediately inserted through the opening 121.
- the flexible sheets 11 and 12 can be flat, but they can also be curved, as in FIGS. 2 to 4, for example by thermoforming.
