Definitions
- the present invention relates to a cap for a container neck.
- the invention relates more particularly to so-called “snaps" or
- Spap that is to say the caps having a tubular skirt adapted to be removably clipped internally around the neck of a container, unlike screwed caps for example.
- This type of stopper frequently includes an outer projecting tab of the skirt, so that the user can apply a manual drive force to unclip the cap .
- the extent and the angular position of the tab following the periphery of the skirt are advantageously predetermined according to other characteristics of the cap associated with its opening. For example, by providing that the tab extends less than a quarter of a circle around the central axis of the skirt, and this on the front side of the cap, that is to say the side intended to be turned into service to the user, it then intuitively understands that the cap is tipped backwards using the tab.
- the heads tend to catch the plugs crooked and, above all, they are unable to center accurately on the neck of the container before putting them on, because the presence of the tab shifts "artificially" the position of the central axis of the head with respect to the central axis of the skirt. The quality of the bottling is compromised.
- the object of the present invention is to provide a miter clip cap, of the type mentioned above, which can be set up accurately and efficiently by conventional bottling heads.
- the invention relates to a cap for a container neck, as defined in claim 1.
- the idea behind the invention is to maintain good visibility of the tab to attention of the user, while providing the skirt with a gripping flange for a conventional bottling head, the collar being sized to perfectly center the skirt in this head.
- the circular profile of the flange runs over more than a semicircle around the central axis of the skirt, which ensures a sufficient gripping range for the bottling heads, while at the same time, this collar has a radial dimension, relative to the central axis of the skirt, equal to the maximum radial dimension of the tab, which allows the flange to compensate for the transverse offset of the position of the axis of the head, related to the presence of the tab.
- the flange has a radial extent, with respect to the skirt, which is equal to the maximum radial extent of the tab.
- FIG. 1 is a perspective view of a plug according to the invention, placed around a container neck;
- FIG. 2 is an elevational view along the arrow II of Figure 1;
- FIGS. 3 and 4 are longitudinal sections of the cap, shown before its introduction around the container neck, respectively along the lines III-III and IV-IV of Figure 2.
- FIGs 1 to 4 there is shown a plug 1 adapted to be clipped releasably on a neck 2 of a container, the plug 1 being generally referred to as "snap cap” or “snape cap”.
- the neck 2 is integral with the rest of the container, especially when the latter is a glass or plastic bottle as in Figure 1, or adapted to be secured permanently to a wall of the container, to level of an opening through this wall.
- the plug 1 and the neck 2 have respective generally tubular shapes, whose central longitudinal axes are substantially merged, under the reference X-X, when the cap is fixed on the neck.
- the following description is oriented by considering that the terms “upper” and “top” correspond to a direction generally parallel to the axis XX and from the body of the container to its neck 2, that is to say say a direction directed to the upper part of Figures 1, 3 and 4, while the terms “lower” and “lower” correspond to an opposite direction.
- the neck 2 comprises a generally cylindrical body 4 with a circular base of axis XX. As shown in phantom only in the right portion of Figures 3 and 4, the body 4 defines, at its upper end, a rim 3 at which the liquid in the container is intended to be poured. On the outer face of the body 4, the neck 2 has, at its upper end, an edge 5 and, in its current portion, a boss 6, this edge and this boss both extending radially outwardly from the body.
- the plug 1 is made of a semi-rigid plastic material, such as polypropylene or polyethylene, shaped by molding.
- the plug 1, considered clipped on the neck 2 is open at its lower end and closed at its upper end by a bottom wall 10, at the outer periphery of which extends axially downwardly a tubular skirt 12 centered on the XX axis and, in the example considered here, a generally annular section with a circular base.
- the bottom wall 10 extends above and across the neck, while the skirt 12 externally surrounds the body 4 of the neck.
- the skirt 12 is provided with an outer tab 14, which extends radially projecting outwardly from the cylindrical outer side face 12A of the skirt.
- This tab 14 runs, along the outer periphery of the skirt, only on a restricted peripheral portion ⁇ 2 ⁇ of the skirt 12, this portion being considered as the front side of the cap 1 to the extent that this side is intended in service to be directed to the user.
- the portion 12i is extended on a non-zero angle, in practice greater than at least a few degrees, and less than 90 °. In the exemplary embodiment considered in the figures, the portion 12i is extended over approximately 50 °.
- the tab 14 comprises, on the one hand, a running portion 14i, whose outer profile, in cross section along the axis XX, is rectilinear in a direction orthoradial to the axis XX and, on the other hand, two end portions 14 2 , whose outer profile, always in cross section along the axis XX, is curved so as to connect the current portion 14i to the outer face 12A of the skirt 12 by gradually decreasing the radial extent of protruding tab 14 relative to this face 12A.
- the radial distance between this axis and the outer profile of the tab 14 has two maximum values, referenced R 1 4 in FIG. 2 and located respectively at the two connection zones between the current portion 14i and both end portions 14 2 .
- the tab 14 has a plane of symmetry P, which passes through the axis XX, as clearly visible in FIG.
- the skirt 12 is provided with an outer flange 16 which extends radially outwardly projecting from the face 12A, and only on a portion peripheral 12 2 of the skirt.
- the peripheral extent of the portion 12 2 is strictly greater than that of the portion 12i, while being however limited by the fact that these portions 12i and 12 2 must be distinct from one another along the periphery of the skirt 12.
- the portions 12i and 12 2 do not overlap and are separated from each other by two peripheral portions 12 3 , which are respectively located on either side of the portions 2 ⁇ and 12 2 along the periphery of the skirt and which, between the tab and the collar, are devoid of any element projecting from the face 12A.
- the portion 12 2 of the flange 16 must be extended over more than 180 °.
- the release of the portions 12 3 must be sufficient so that the user can easily distinguish visually the tab 14 and the flange 16 along the periphery of the skirt 12, so that each portion 12 3 is extended. at least 5 ° around the XX axis.
- the portion 12 2 extends over approximately 290 ° while each portion 12 3 is extended over approximately 10 °, being furthermore noted that, here, the plane P forms a plane of symmetry for the collar 16.
- the flange 16 includes, along the periphery of the skirt, on the one hand, a running part 16i, the outer profile of which, in cross-section with the axis XX, is circular and centered on this axis, and, secondly, two end portions 16 2 , whose outer profile, always in cross section along the axis XX, is curved so as to connect the current portion 16i to the outer face 12A of the skirt 12 by progressively decreasing the projecting radial extent of the flange with respect to this face 12A.
- the current portion 16i constitutes the bulk of the flange 16, in the sense that this portion 16i runs over more than 180 ° about the axis XX, preferably about 200 ° as in the example shown in the figures.
- the circular outer profile of the portion 16i of the collar 16 has a radius Ri 6 equal to a molding clearance, at the radial distance Ri 4 associated with the tab 14.
- the parts of the skirt 12 which respectively connect the bottom wall 10 to the tab and to the flange have respective outer surfaces. 12Ai and 12A 2 different: the surface 12A 2 corresponds to a cylindrical portion of circular base, centered on the axis XX, and is connected to the upper flat surface 10A of the bottom wall 10 angularly, generally at right angles , as clearly visible in the right part of FIGS. 3 and 4, while the surface 12Ai corresponds to a truncated cone portion, centered on the axis XX and converging towards the bottom wall 10, thus connecting the tab 14 and the surface 10A more bluntly than the surface 12A 2 , as clearly visible in the left part of FIG. 3.
- the blunt surface 12Ai extends on either side of the portion 12i, along the outer periphery of the skirt 12, at the portions 12 3 to connect progressively at the cylindrical surface 12A 2 .
- the skirt In the upper part of the skirt 12, approximately at the same axial level as the tab 14, the skirt is internally provided with a clipping band 18 in the form of a bulge of material extending radially inward from the skirt wall.
- this clipping band 18 In longitudinal section of the stopper 1, this clipping band 18 has a convex surface 18A, which is connected to the bottom wall 10 forming a receiving recess 20 complementary to the edge 5 of the neck 2.
- the clipping of the cap consists of engaging the convex surface 18A with the lower end of the edge 5, the latter then being received in the recess 20 and the bottom wall 10 being then pressed against the rim 3, as shown in the right part of FIGS. 4.
- the unclipping of the stopper consists in disengaging the strip 1 8 and the edge 5, in initiating this disengagement from the front side of the plug 1 and this by acting on the tab 14, in particular by applying to this tab a force F directed upwards and in a direction parallel to the axis XX or, more frequently, slightly inclined by relative to this axis, as indicated in FIG. 3.
- the strip 18 does not run continuously over the entire inner periphery of the skirt 12, but is advantageously interrupted at least at the level of the portions. 12 3 , as clearly visible in the left part of FIG. 4.
- the skirt 12 is adapted to separate into two distinct parts, namely an upper portion 12.1, integral with the bottom wall 10, and a lower portion 12.2 initially connected to the upper portion 12.1 by a weakening peripheral line 22 located axially in the current portion of the skirt and schematized in the figures by dashed lines.
- the skirt portion 12.1 is intended to be disengaged from the neck 2, so that this portion 12.1 externally carries the tab 14 and, internally, the clipping strip 18.
- the skirt portion 12.2 is, in turn, intended to remain around the neck 2.
- this portion 12.2 is provided internally with a pallet 24 extending radially inwardly projecting from the inner surface of the skirt 12, running over the entire periphery of the skirt. When the cap is assembled at the neck 2, this pallet 24 extends axially below the boss 6 and is adapted, when the cap is then raised for the first time, to abut axially against this boss.
- this line comprises a succession of peripheral slots, not shown in detail in the figures, which locally weaken the skirt 12 and which delimit between them bridges, obtained during the molding of the cap 1 or by cutouts in the cap. mold outlet.
- the weakening line 22 has a lower breaking strength at the skirt portion 12i than in the rest of the skirt along its periphery.
- this lower breaking strength is linked to the fact that the wall thickness of the current portion of the skirt is reduced at the axial level of the line. weakening 22, and only at the front of the skirt, especially in the skirt portion 12i.
- the weakening line 22 may not extend continuously over the entire periphery of the skirt 12 but, on the contrary, be interrupted on the rear side of the cap 1, in particular in a peripheral portion of the skirt diametrically opposed to the portion 12i. In this way, the rupture of the line 22 does not allow to completely disengage the skirt portion 12.1 relative to the skirt portion 12.2 and the collar 2, since a non-breakable material link remains then to connect the skirt portions 12.1 and 12.2, forming a tilting hinge between these skirt portions.
- the assembly of the stopper 1 at the container neck is carried out using a bottling head, not shown in the figures.
- various types of heads may be used, in particular ball heads, vacuum-gripping heads, cone heads, gripper heads, and the like.
- these heads allow the gripping of the cap 1, by enclosing it externally peripherally: this head applies gripping forces T substantially radial to the axis XX, according to a gripping contour C of circular shape, centered on the central axis of the head, as shown in Figure 2. More specifically, the head adjusts the size of its circular gripping contour C so that this contour has a radius equal to the radius Ri 6 , which amounts to doing coincide the contour C with the circular outer profile of the running part 16i of the collar 16.
- this flange portion 16i extends over more than 180 ° about the axis XX and, on the other hand, the tab 14 is inscribed entirely within a circle centered on the axis XX and of radius R 16 , the gripping head and the skirt 12 are positioned coaxially, being centered on the XX axis.
- the tab 14 forms, at its two junction zones between its current portion 14i and its end portions 14 2 , two potential radial support zones. for the gripping head, as indicated by the two efforts T respectively applied to these two areas in Figure 2. The quality of the gripping of the plug 1 is improved. Once the gripping head has thus grasped the plug 1 coaxially, it engages it in force on the neck 2 in the direction of the axis XX, until clipping the band 18 with the edge 5.
- the tab and the flange may be located at respective respective axial levels of the moment that the gripper head used for catching the plug 1 is not embarrassed to adjust its circular gripping contour C at least on the circular outer profile of the flange;
- the projecting tab 14 may have other external contours than that contemplated in the figures; in particular, the current portion 14i of the tab may have a circular outer profile, centered on the axis XX and whose radius is substantially equal to the radius R 16 of the circular running portion 16i of the flange 16; and or
- the plug 1 considered in the figures advantageously comprises a lip 26 which extends axially downwards from the bottom wall 10, centrally on the axis XX, inside the external skirt 12, so that, when the cap is clipped on the neck 2, the lip 26 is pressed sealingly against the inner face of the body 4 of the neck 2; and or
- the body 4 of the neck 2 is externally smooth between the edge 5 and the boss 6; alternatively, it may be threaded, it being understood that this threading would not be used to fix the plug 1 on the neck by screwing, but that the presence of such a thread would not be a problem to put in place the clipped cap 1.
