Definitions

  • the present invention relates to a plugging element, of the threaded plug type, suitable for being removably placed on a container, in the form including a glass jar, bottle, flask, or other form again.
  • the invention is particularly suitable for plugging pots in glass such as those used for packaging skincare creams.
  • a plugging element comprising a first thread capable of cooperating with a second thread, formed by a container intended to receive said plugging element, characterized in that it comprises elastically deformable means capable, in position of engagement of said first and second threads, to be supported elastic said plugging member on said container according to at least one direction oriented radially with respect to said closure element, so as to improve the resistance of the closure element on the container.
  • said elastically deformable means are suitable for position of engagement of said first and second threads, to be maintained in elastic support at least a portion of the first thread on at least one corresponding portion of the second thread.
  • the presence of these means elastically deformable performs "braking" of the thread during screwing / unscrewing the plugging element. In other words, we can thus obtain a zero or almost zero functional clearance thus improving in a way the quality of the packaging.
  • said closure element comprises a side skirt carrying said first thread, said means elastically deformable consisting of at least one elastically deformable portion of said skirt, and whose radius of curvature at rest is different from the radius of curvature of the rest of the skirt.
  • the first thread is preferably made on the inner wall of the side skirt, so that ability to engage with second thread carried by wall external of a neck formed by the container.
  • said elastically deformable means consist of at least minus a "flat" formed by said skirt.
  • a flat may, in the case of a closure element obtained by molding a thermoplastic material, being obtained by applying a deformation to the side skirt, at its exit from the mold, and before the material is completely cooled.
  • the flat is also obtained directly from molding, in giving the mold the appropriate shape.
  • the closure element comprises two elastically means deformable diametrically opposite.
  • each of said elastically deformable strips is delimited at least in part by a light formed in said side skirt in the vicinity of the transverse plate.
  • each light is associated with a elastically deformable strip.
  • Each of the bands elastically deformable extends over the entire angular width of the light corresponding, and is delimited on the one hand by an edge of the light and on the other part, by the free edge of the side skirt, located opposite the light.
  • the element of plugging includes two lights located outside the angular portions free of threads.
  • the two lights are diametrically opposite.
  • the two lights are centered on an axis substantially perpendicular to an axis on which are centered the two thread-free portions. The release of these two lights is allowed when moving the two parts closer sides of the mold.
  • a closure element obtained by molding it can be formed of a thermoplastic material, in particular a polyethylene or a polypropylene.
  • the plugging element can be coated with an external covering, the function is mainly aesthetic, in particular by hiding the lights made in the side skirt of the closure element.
  • the dressing exterior makes it possible to reinforce the rigidity of the structure carrying the thread. This dressing also allows the use of materials whose aesthetics are particularly suitable for areas such as cosmetics.
  • the element of clogging can be made integral with the exterior cladding by any technique appropriate, in particular by bonding, welding, or breakdown.
  • a container is also produced comprising a closure element according to the invention.
  • said container is made of glass. It can especially be a pot intended for the conditioning of a care cream.
  • the container 1 shown in FIG. 1 comprises a body 2, one end of which is closed by a bottom 3 and the other end of which ends with a neck 4 whose a free edge 5 defines an opening 6.
  • the outer surface of the neck 4 has a suitable thread 7, as will be seen in more detail below. cooperate with a corresponding thread (11, FIG. 2A) of an element of plugging 10.
  • the plugging element 10 includes an internal part 12, arranged inside an external covering 13.
  • the part 12 can be mounted inside the external covering 13, by bonding, welding, or breakdown.
  • Part 12 has a transverse wall 14 whose edge is folded at 90 ° to form a side skirt 15, on the surface internal of which is disposed the thread 11.
  • the side skirt has two lights 24, 25, diametrically opposite, located in the vicinity of the junction between the transverse wall 14 and the side skirt 15, which will be discussed again in more detail later.
  • FIGS 2A and 2B illustrate in more detail, part 12 of the plugging element 10.
  • this part 12 includes a bottom or wall transverse 14 whose edge is folded at 90 ° to form a lateral skirt 15.
  • the internal surface of the side skirt 15 carries a thread 11, formed of two parts 20, 21, separated by two skirt portions 22, 23, free of any thread.
  • the two portions 22, 23 are diametrically opposite, and centered along an axis X.
  • the side skirt 15 also has two openings 24, 25, crossing the thickness of the skirt 15.
  • the two openings 24, 25 extend parallel to the plane of the bottom 14, and formed substantially at the junction between the bottom 14 and the side skirt 15.
  • the two lights 24, 25 are centered on a Y axis perpendicular to the X axis.
  • the upper edge 26 of the light 24 delimits with the free edge portion 27 of the skirt located opposite the light 24, a first portion resiliently deformable 28.
  • the upper edge 29 of the light 25 delimits with the free edge portion 30 of the skirt located opposite the light 25, a second elastically deformable portion 31.
  • these two portions 28, 31 are, after demolding, and before complete cooling of the material, flattened using a suitable tool, so as to form two diametrically opposite flats.
  • the flattening of these two portions 28, 31 can result from a displacement ⁇ of material which can range from a few 10 th of mm to several mm.
  • the two portions 28, 31 are frozen in the position shown in FIG. 2B.
  • these two portions 28, 31 will allow an elastic tightening of the part 12 of the closure element on the neck of the container 1, and this, in two diametrically opposite zones, thus compensating for any play related to the manufacturing tolerances of the glass thread 7 of the container 1.
  • two thread portions are produced with a diameter or radius of curvature different from the diameter or radius of curvature of the rest of the thread 11, thus allowing , when the part 12 is screwed onto the neck 4 of the container, to produce a braked screwing, and, therefore, good resistance of the plugging element 10 on the container 1.
  • FIGS. 3A-3C illustrate an embodiment of the mold used for the realization of the portion 12 of the closure element shown in FIGS. 2A and 2B.
  • the mold consists of three parts : two lateral parts 100, 101, and a central part 102.
  • Each of the lateral parts presents the reliefs 103, 104, necessary on the one hand, for the production of portions 20, 21 of thread 11, and secondly, production of lights 24, 25.
  • the side wall 105 of the central part 102 is free of all relief.
  • the central part 102 is retracted from the as shown in Figure 3B.
  • the side parts 101, 103 are brought together so as to release the reliefs 103, 104 from the corresponding hollow parts formed in the molded part, thus allowing the part 12 to be removed from the mold. 12 at the outlet of the mold, conforms to what is shown in Figure 2A.
  • the two portions 28 and 31 are flattened the manner shown in Figure 2B.
  • the flattened shape at the level of the two elastically deformable bands 28, 31 results directly from molding, in giving the lateral parts 100 and 101 of the mold, the flattened shape corresponding. So the part comes out of the mold, directly with the shape required.
