Definitions

  • the present invention relates to a device of the "pocket aerosol" type.
  • Such containers are suitable in particular for packaging cosmetic products, including hair products, personal care products, makeup or skincare.
  • Devices of this type are devices capable of containing and dispensing under pressure of liquid or pasty materials. They have a container rigid outer and a flexible inner container, preferably made of aluminum or plastic material, the upper edge of which is fixed to the outer container. They also include a dispensing valve generally mounted on a cup. The bottom of the outer container usually has an opening closable for the introduction of a propellant into the volume formed between the outer container and the inner container.
  • the flexible internal container, or “pocket” usually contains the consumer product, while the annular chamber, between the pocket and the external container or “housing aerosol "is filled with a propellant, ie a gas under pressure.
  • a propellant ie a gas under pressure.
  • the dispensing valve is opened, i.e. by pushing in either by tilting, via a distribution head in the form of a pushbutton. The pressure exerted by the propellant on the pocket acts and expels the product through the dispensing valve out of the pocket.
  • the aerosol container (outer container) generally has a bottom and a cylindrical body, ending at its end opposite the bottom by a part domed or "dome” including a free edge, configured as a rolled edge, defines an opening.
  • a piece in form of metallic disc called "cup”.
  • the dispensing valve is attached generally in the center of the cup and is thus in the axis of the aerosol at poached.
  • the cup has a peripheral flange intended to ensure the fixing of the cup by crimping on the rolled edge of the outer container.
  • the tightening of the cup on the dome is done by swaging, that is to say by deforming the cup from the inside, so as to flatten it against the inner surface of the dome of the outer container, the deformation caused causing the flange to be tightened on the rolled edge.
  • the seal between the flange of the cup and the rolled edge of the container is generally provided by an elastic seal.
  • the bag In bag aerosols, the bag is usually attached to the body at the level of the crimping of the cup on the rolled edge, the pocket being suspended by its neck in the axis of the aerosol can.
  • the pocket neck ends in part upper by a rim of dimension allowing it on the one hand to be inserted in the collar of the cup, and on the other hand to rest on the rolled edge of the dome.
  • the rim of the pocket found clamped between the cup collar and the rolled edge.
  • the precision of mounting must seal between the three elements; cup, pocket, and rolled edge of the outer container.
  • the seal between the pocket and the container exterior is generally the most delicate due to the transience of the gas propellant, and due to the nature of the material forming the pocket. Indeed, the material is generally a plastic material, not very elastic, such as polypropylene or polyethylene.
  • a device for packaging and distribution under pressure of a product contained in a pocket with flexible walls in communication with a valve said tank being disposed in an external container, a propellant being contained in the volume formed between the outer container and the bag, said valve being mounted on a cup, means for fixing the cup and an open edge pocket, on one edge of the outer container, a seal allowing, when compressed between the fixing means and the edge of the container, form a seal between the gas, the product, and the outside, a setback being formed either by the seal in the uncompressed position or by the fixing means, either by the edge of the outer container, so as to ensure compression substantially uniform of at least part of the seal, both and on the other of said recess.
  • a first portion of the seal is sandwiched between the edge of the outer container and the open edge of the pocket, or between the open edge of the pocket and the fixing means.
  • the portion of the seal, sandwiched between the edge of the container outside and the open edge of the pocket, or between the open edge of the pocket and the fixing means consists of an inner annular part of said seal sealing.
  • the open edge of the pocket is arranged opposite the setback, and preferably substantially in contact with the latter. Of such positioning, it follows that the pocket does not generate any excess thickness, likely to significantly modify the degree of compression of the joint seal, when sandwiched between the container and the valve cup.
  • the seal is formed a separate item from the pocket. It provides a much better seal.
  • the sealing function being carried out by an element separate from the pocket, it is possible to use materials to make the pocket, providing good better compatibility with certain products to be packaged, in particular some cosmetic products.
  • a second portion of the seal is clamped directly between the edge of the container and the fixing means.
  • the portion of the seal, sandwiched directly between the edge of the container and the fixing means is formed of an annular portion outside of the seal.
  • the step is of thickness substantially equal to the thickness from the open edge of the pocket.
  • the part of the seal located opposite the edge of the pocket undergoes a compression rate substantially identical to the rate of compression of the part of the joint extending beyond the free edge of the pocket.
  • the gas / product, product / exterior, and gas / exterior seals are good quality.
  • the step is formed by the seal sealing.
  • the seal has an internal annular portion of thinner, the recess being formed on one or the other of the faces of the seal according to the respective position of the seal relative to the pocket, to fixing means, and at the edge of the external container.
  • Such a seal can be obtained molding, or cutting.
  • the step is formed by a folded annular edge, or "flange" of the cup, constituting said fixing means.
  • the step is formed by a folded annular edge, or "rolled edge" of the outer container.
  • the latter is disposed on a part of its radial width between the free edge of the pocket and the means of fixation.
  • the seal is arranged on a part of its radial width between the free edge of the pocket and the rolled edge of the outer container.
  • the thickness of the step can be between 0.03 mm and 1 mm, and preferably between 0.1 mm and 0.5 mm.
  • Attaching the cup and an open edge of the pocket to an edge of the container exterior can be obtained by crimping or by swaging.
  • the aerosol device 1 represented in FIG. 1 comprises an external container 2 having a bottom 9, and the upper part 3 of which ends substantially in dome shape.
  • the dome ends with a rolled edge 4 delimiting an opening 5.
  • a flexible bag 6, containing the product to be dispensed P, is disposed at inside the container 2.
  • the annular chamber 8, between the pocket 6 and the external container 2 is filled with a propellant G.
  • a valve 10 is arranged in the bottom 9 of the outer container so as to allow the introduction of the propellant into the annular volume 8.
  • a disc-shaped part metallic, called "cup" 11 On the rolled edge 4 of the container, is mounted a disc-shaped part metallic, called "cup" 11.
  • the dispensing valve 12 is fixed generally in the center of the cup 11 and is thus in the axis of the aerosol pocket.
  • the valve 12 comprises a valve stem 14 whose actuation is generally carried out by means of a push button (not shown).
  • the cup 11 has a peripheral flange 13 intended to ensure the fixing of the cup 11 by expansion, that is to say by deforming the cup 11 from the inside, so as to press it against the internal surface of the dome 3 of the outer container 2, the deformation generated causing the tightening of the flange 13 on the rolled edge 4.
  • the seal between the flange 13 of the cup 11 and the rolled edge 4 of the container is generally provided by an elastic seal 20 which will be discussed in more detail later.
  • the pocket 6 is fixed at the crimping of the cup 11 on the rolled edge 4, the pocket being suspended by its neck in the axis of the aerosol can.
  • the pass of the pocket ends in its upper part with a rim 15 of dimension allowing on the one hand to be inserted in the collar 13 of the cup, and on the other hand part to rest on the rolled edge 4, via the seal 20.
  • the rim 15 of the pocket 6 is clamped between the flange 13 of the cup 11 and the rolled edge 4.
  • the assembly thus formed can be mounted in industry in a similar manner to that which is described in patent FR-A-2 310 287 to which reference was made above.
  • the valve is opened, either by insertion either by tilting, via a distribution head in the form of a pushbutton.
  • the pressure exerted by the propellant on the pocket acts and expels the product through the dispensing valve out of the pocket.
  • the "magnifying glass" in Figure 1, as well as Figures 2 and 3 illustrate more specifies how the gas / product / exterior seal is obtained according to a first embodiment.
  • the seal 20, as shown in the non-position mounted in Figure 2 is in the form of a flat annular element 21 comprising an inner annular part 23 of smaller thickness and a part outer annular 22 of greater thickness.
  • a step 24 is thus formed between the inner annular part 23 and the outer annular part 22.
  • the offset 24 is of height substantially equal to the thickness of the free edge 15 pocket 6.
  • the seal 20 rests directly on the rolled edge 4 of the container 2. Due to the presence of the offset 24, when the free edge 15 of the pocket 6 rests on the portion internal annular 23 of the seal 20, the free edge does not form any excess thickness by relative to the upper surface of the outer annular part 22.
  • the compression of seal 20 is substantially uniform over an annular zone extending both on one side of the recess 24, and on the other side of the offset 24.
  • the seals between the annular volume 8 and outside, between the annular volume 8 and the pocket 6, and between the pocket 6 and the exterior is remarkable.
  • the seal 20 is placed on the free edge 15 of the pocket 6.
  • the inner annular part 23 of the seal 20 is in direct contact with the flange 13 of the cup 11.
  • the seal 20 illustrated in FIG. 2 has been turned over.
  • the free edge does not form extra thickness compared to the lower surface of the outer annular part 22.
  • the compression of the seal 20 is substantially uniform over an area annular extending both on one side of the recess 24, and on the other side of the offset 24.
  • the seals obtained are similar to those obtained with the previous variant.
  • FIG. 5 illustrates a second embodiment of the device according to the invention.
  • the general configuration of device 1 is identical to that of device 1 of the Figure 1, and therefore does not require further description. It is note however that according to this embodiment, the cup 11 is mounted by external crimping of the flange 13 on the rolled edge 4.
  • the difference between the two embodiments relates to the realization of the seals, in particular to the position of the offset. This difference between the two embodiments will be described in more detail with reference to the "magnifying glass" in FIG. 5.
  • the seal 20 is of constant thickness.
  • the rolled edge 4 forms a step 32 separating a inner annular portion 30 of thinner thickness, of an annular portion outer 31 of greater thickness.
  • the difference in thickness corresponds substantially to the thickness of the free edge 15 of the pocket 6.
  • the compression of the seal 20 is substantially uniform over an area annular extending partly, on one side of the recess 32, and partly, of the other side of the offset 32.
  • the seals between the volume annular 8 and outside, between the annular volume 8 and the pocket 6, and between the pocket 6 and the outside, are remarkable.
  • FIG. 4 being a variant of Figure 6.
  • the seal 20 is, at rest, thick constant.
  • the rolled edge 4 of the outer container 2 is also thick constant.
  • the free edge 15 of the pocket 6 is disposed between the seal 20 and the edge rolled 4 of the outer container.

  • a corresponding recess 43 exists inside the collar.
  • the recesses 42 and 43 can be obtained by forming the metal during the strikes the collar.
  • the seal 20 of thickness constant, is arranged between the free edge 15 of the pocket 6 and the rolled edge 4 of the outer container.
  • the free edge 15 of the pocket 6 is disposed between the seal 20 and the flange 13 of the cup 11, in abutment against the step 43.
  • the edge free 15 of the pocket 6 does not generate excess thickness relative to the surface internal of the collar 13.
  • the compression of the seal 20 is substantially uniform over an annular zone extending in part on one side of the step 43, and partly on the other side of step 43.
