Definitions

  • the present invention relates to an element, of removable type hood, according to the preamble of claim 1 for overcome a conditioning device.
  • the invention is particularly suitable hoods used to comb the packaging sets as used in the cosmetics, such as perfumes, body deodorants, lacquers styling, sprays, etc., in the field of pharmacy, or the household field.
  • the container In the field of cosmetics, and in particular in the field of aerosols, or other spraying devices, the container is covered with a hood removable, traditionally mounted by breakdown.
  • the upper part of container has a groove or groove for receiving a ring or a plurality of notches formed on the inner surface of the hood, in the vicinity of its free edge.
  • an axial pressure exerted on the cover causes a elastic deformation of the hood walls carrying the snap ring or notches, which deviate radially to cross the edge adjacent to the groove or groove. After crossing the edge by the notches, these are held by elastic return in the bottom of the throat, which holds the hood in place on the container.
  • the groove or groove may be replaced by a protruding bead on the surface external container.
  • Patent Application DE 29 08 111 discloses a closure cap comprising a skirt in which is mounted a tamper-evident element. The latter presents a flange for locking the cap on a container. The inviolability element can be depressed to allow removal of the cap.
  • hood When the hood is made by molding, it may be desirable, especially for reasons of cost of manufacture to be able to unmold the hood by tearing. Unfortunately, such a pulling causes damage to the ring or notches, this which produces a hanging or tightening of the cover on the container whose hardness varies so considerable from one container to another. Thus, for some containers, the hanging will be clearly insufficient.
  • hood intended to be mounted by snapping on a container, and whose strength of attachment on the container can be adjusted according to the need.
  • a cover for covering removable manner an X-axis container, said container having an edge of breakdown to be crossed by at least one notch carried by at least one elastically deformable portion of said cover, in response to an axial force exerted on the hood, characterized in that the hood comprises means for adjusting the elasticity of at least one of the elastically deformable parts, so as to modify the axial force required, when opening and closing, to crossing the edge, by said notches.
  • the breakdown edge is understood to be either the edge of a recessed portion (groove or groove, recess) and in which, during mounting, the notches are housed, or a protruding bead on the surface of the container, and behind which the notches are lodged.
  • the recess can be formed from the part under the crimp collar of the valve.
  • hood aims in particular any means of closure (bonnet, cap, cap, capsule, cover, etc.) or other accessory (applicator, etc.) capable of overcoming removably a container in any form whatsoever (tube, bottle, pot, bottle, box, can, etc.)
  • a cover adapted to be mounted by snapping on a container.
  • the tightening among several values (a tightening strong, medium or weak, for example).
  • the choice of the tightening is made during the assembly of cover.
  • the hood tightening is identical from one hood to another.
  • the same hood can be used for a woman product line or a line of product man. It is only necessary to change the setting of the hood tightening.
  • the means for adjusting the elasticity of the parts elastically deformable elements comprise a body mounted on the hood, and whose position angular or axial to the hood determines the elasticity of the parts elastically deformable.
  • the cover comprises three tabs arranged regularly on said inner wall.
  • said edge forms at least one ramp, so that when said ramp is located opposite a tab elastically deformable, depending on the angular position of said ring relative to said tab, the average axial height of the free leg portion located between said free end and the edge varies, thereby modifying the elasticity of said tab, means being provided for immobilizing in a position given angle, said ring inside the annular space.
  • said edge forms as many ramps as there are legs elastically deformable.
  • the surface of the ring is progressively modified with respect to the upper part of the flexible leg, which consequently changes the height axial axis of the free part of the leg (lower part).
  • the leg is more or less flexible, and will deform more or less easily for allow the crossing of the edge of breakdown by the notches.
  • the strength to exercise for mounting / disassembly of the cover will be more or less strong.
  • Said ring may have, opposite said edge, a substantially straight edge, said substantially straight edge being, in the mounted position of the ring on the hood, located substantially opposite the first end of said tabs.
  • the means for immobilizing the ring in a position given angle may comprise an axial rib provided on a inner surface of the outer wall, and able to come into engagement with a groove selected from a plurality of axial grooves disposed on a surface external of said ring.
  • the ring can be further maintained axially in said annular space by breakdown or self-tightening assembly.
  • said edge is, at least on a portion located opposite a leg, substantially straight and perpendicular to the axis X, the average axial height the free leg portion between said free end and said edge, being adjusted by changing the axial position of said ring in said space ring, means being provided for axially immobilizing said ring in said annular space.
  • the ring can be immobilized axially by snapping, self-tightening, or any other appropriate means.
  • the cover is covered with a covering outside.
  • the inner wall and the outer wall can form a single piece obtained from molding a thermoplastic material, said outer wall having each elastically deformable tab, a release so as to allow the demolding of said elastically deformable tabs.
  • the ring can be obtained by molding a selected thermoplastic material among polypropylenes or high density polyethylenes.
  • a set of packaging and dispensing comprising a container containing a product, and a hood surmounting said container, characterized in that the hood conforms to the invention.
  • the product may be a cosmetic product, a pharmaceutical product, or a household product.
  • FIG. 1A to which reference is now made, we see a view exploded of an embodiment of the hood 1 according to the invention.
  • This one includes mainly a body 2 obtained from molding a plastic material such as a polypropylene, high density polyethylene, or polyethylene terephthalate.
  • the body has an inner wall 3 and an outer wall 4 connected in the vicinity of one their ends by an annular transverse wall 5. The other end said inner and outer walls are free so that said walls internal and external define between them an annular space 6.
  • the inner wall 3 is of slightly lower axial height at the axial height of the outer wall 4.
  • the inner wall 3 has three elastically deformable tabs 7, oriented axially, and spaced angularly at 120 °.
  • Each of the legs 7 presents a free end 9 in the vicinity of the annular wall 5, and bearing on its surface 10 end.
  • the end 8, opposite to the free end is integral with the inner wall.
  • the tab 7 is delimited also by two edges 11, 12, separated from the inner wall by a thin slot extending over substantially the entire height of the tab 7.
  • the outer wall 4 has a recess 13 of substantially identical surface on the surface of the legs 7, so as to allow the release of the legs 7.
  • the inner surface of the outer wall 4 comprises an axial bead (or rib) 14 whose purpose will be described in more detail later.
  • the hood illustrated in FIG. 1A also comprises a ring 15, of thickness slightly smaller than the width of the annular space 6, so as to be able to insert into said annular space.
