Definitions

  • the present invention relates to a device for closing a bottle with a neck of the type comprising on the one hand, a neck adapter having an external skirt for fixing to the neck of the bottle and an internal closure sleeve and, on the other hand, a cap intended to be inserted in the closure sleeve of the neck adapter.
  • the neck adapter is a one-piece plastic part and the seal between the bottle and the adapter is obtained by the forced passage of a rod under the profile of the neck of the bottle.
  • the adapter must withstand significant stresses, and in particular tensions which are accentuated by the contact of the products and vapors contained in the bottle, which can cause cracking or stress-cracking (stress cracking) of the material.
  • the object of the invention is to provide a perfectly secure closure device, in which the neck adapter np is not likely to be put out of use.
  • the neck adapter consists of two separate parts, namely a sleeve-carrying plate constituted by the closure sleeve surrounded at its upper part by an external peripheral flange intended to press tightly on the upper edge of the neck of the bottle, and a cap formed by the outer skirt for fixing to the neck of the bottle and having an internal peripheral rim which covers over at least part of the external flange of the carrier plate sleeve, the two parts being made integral so as to allow manipulation of the adapter in a single assembly, while dissociating the neck adapter with regard to internal stresses likely to develop there.
  • the neck adapter can appear externally in its traditional appearance and be apparently one-piece: it lends itself to all conventional handling operations in the same way as the traditional neck adapter, in particular to automatic dispensing operations on the bottles.
  • the constitution of the neck adapter according to the invention facilitates manufacturing by molding.
  • the upper surface of the flange of the sleeve-bearing plate has a peripheral shoulder providing a peripheral housing for rigorous insertion of the internal rim of the cap, whereby the plate and the cap can be forcibly assembled and thus made integral.
  • Different embodiments can be provided to ensure the mechanical joining of the two parts. This is how they can be made integral by means of a snap-fastening of the internal rim in a complementary shoulder of the flange of the sleeve-carrying plate, or else, thanks to a crimping lip provided on the flange of the plate and which crimp internal rim of the cap, or else, by snapping the flange of the plate into a recess provided at the birth of the skirt of the cap, or finally; thanks to the embedding profiles carried on the facing faces of the internal rim of the cap and the flange,
  • FIG. 1 shows the first part, according to the invention, of the neck adapter, the sleeve-holder plate 1, comprising a reverse frustoconical sleeve 2 surrounded at its upper part by a generally circular external peripheral flange 3.
  • a shoulder 4 is formed so as to reserve a peripheral housing 5, generally circular, of rigorous insertion of the cap 6 from there FIG. 2.
  • the diameter of the shoulder 4 and that of the orifice 9 are calibrated so as to adjust mechanically one inside the other (with a tolerance of 1/10 mm for example ) by force assembly facilitated by chamfers provided on the edges of the orifice 9 and the shoulder 4.
  • This is formed of an outer skirt 7, generally cylindrical, and provided with an internal peripheral rim 8, under crown shape, the dimensions of which allow it to be adjusted to the housing 5 of the sleeve-carrying plate 1, with the effect of centering the central orifice 9 around the shoulder 4.
  • Figure 3 shows the mounting of the sleeve holder plate 1 and the cap 6 on the neck 10 of a bottle.
  • the annular flange 3 of the plate 1 comes to bear in leaktight fashion on a flat 11 (or other profile allowing sealing) formed on the upper edge of the neck 10, while the closure sleeve 2 is inserted with play in the neck .
  • the fixing cap 6 comes, above, to be housed by its internal rim 8 in the housing 5 and is centered, on the one hand, by the cooperation of the internal rim 8 and the shoulder 4 es on the other hand, by the cooperation of the periphery of the flange 3 with the internal surface of the cylindrical skirt 7 of the cover 6.
  • the cap For its attachment to the neck, the cap is provided, on the inner surface of its skirt 7, with a continuous or interrupted rod 12, of profile and dimensions determined by those of the annular bulge 13 of the neck 10.
  • a clearance 14 is provided at the base of the skirt 7, on the inner side to facilitate its centering and its installation on the neck of the containers.
  • the cap 6 undergoes relatively high tension stresses due to its fixing by forced pressing on the neck of the bottle, but the cap 6 is out of contact with the harmful products and vapors of the bottle and can bear stress constraints without difficulty. It can be made of a rigid material resistant to tensions.
  • the sleeve-carrying plate is not subjected to any tension: the tensions possibly transferred by the cap on the plate, at the level of the connection, transform, if they even exist, into a radial compression of the central part of the sleeve-carrying plate, this compression being without influence on the service life or the tightness of said plate.
  • the characteristics of the material for making the plate are essentially determined by the flexibility and resistance necessary to obtain a good seal between the flange 3 and the neck 10 of the bottle, on the one hand, between the sleeve and the stopper, on the other hand.
  • the sleeve support plate can be made, for example, of polyethylene, copolymer, butadiene, etc.
  • the plug 16 comprises, apart from the plugging member 17 proper, cooperating with the sleeve 2, an upper disc 15 covering the surface of the neck adapter and provided with two or more lateral fins 18 in the form of cylindrical sectors and comprising a retaining projection 19 cooperating with the lower edge 20 of the skirt of the cover 6 to produce a removable retainer.
  • the shape of the fins 18 contributes to centering the stopper on the neck adapter 1.6.
  • the stopper 16 can be an integral part of a decorative cover associated with the bottle, or constitute a technical piece added in the latter.
  • the sleeve-holder plate 1 can include devices to increase its etanehéotti, such as rods; cylindrical extension of the cone, double wall, etc., its inviolability can be increased by closing the orifice passing through the sleeve. It can also provide reliefs for centering and fixing the cover.
  • the cap may also include other sealing rods, or else devices for locating or fixing: flats, grooves.
  • the cap may also constitute a decorative part by its colors, its shapes, or by subsequent treatments such as metallization, printing, marking, etc.
  • FIGS. 5 to 9 With regard to the connection between the sleeve-carrying plate and the cap, other embodiments are shown in FIGS. 5 to 9.
  • the cap and the plate can snap into place because the rim 8 has an undercut edge 9a which can fit into a shoulder 4a in reverse undercut, provided on the flange 3 of the plate.
  • the height of the shoulder 4 is provided greater than the thickness of the rim 8, and the rim is crimped by forming a lip 21 by direct heating or by ultrasonic waves.
  • male 22 and female 23 hooking devices are provided on the contact surfaces of the flange 8 and of the flange 3.
  • the diameter of the flange 3 of the sleeve-carrying plate is provided greater than the inside diameter of the cap and is introduced into a housing 24 located at the birth of the skirt 7 of the cap. Because of its flexibility, the snap-fastening of the sleeve-holder plate poses no problem.
  • FIG. 8 shows a mixed solution according to which the flange 3 is housed very exactly in the housing 24 of the cap, while the flange 8 of the cap is itself inserted in a housing of the plate formed by the shoulder 4b and the upper lip 25.
  • the advantage of this embodiment is that it can be produced by direct molding of the plate 1 on the cover 6.
  • the preferred materials for making the cap 6 are polypropylene, polyamides, polyesters, polycarbonates, ABS, cellulose acetate, low density polyethylenes
