Definitions

  • the invention relates to a cover for vacuum sealing of large-opening containers, essentially made of glass, a method of manufacturing this cover and improvements made to said containers in order to make them suitable for receiving it.
  • the range of the container was bordered by a peripheral rod placed outside and of a height less than that intended for it (US-A-2,629,509), or even by two similar rods, l 'one outside, the other inside, associated if necessary with an internal ribbing intended to facilitate the cooling of the ring during forming to save its flatness (DE-C-646 921).
  • the existence of the rim makes it possible to develop the seal by molding a mass of plastic material put in place by centrifugal casting in the peripheral concave zone formed by it.
  • the object of the invention is to propose an even more economical route and aims to replace the capsules in question with a simple cover, which can, like the lids of the prior art, simply rest on the opening of the container to become rigidly secured. of it, without screwing or crimping.
  • This cover will be flexible enough to be able to support a very thin joint; it will then be thin enough so that its non-projecting edge can be protected by part of the ring of the container; its manufacture will be simplified and will require a lesser amount of metal than the usual devices.
  • the cover (normally circular in shape) has at its periphery a substantially planar annular part, to one face of which adheres a seal molded in thermoplastic material, and the edge of which comprises a flange folded over a double thickness in the direction of said joint so that the edge of this flange is embedded in the thickness of the latter, leaving it protruding on the underside.
  • the annular part is connected by a frustoconical shoulder to the flat central portion of the cover, so as to allow, without excessive increase in rigidity, as will be explained below, the stacking of containers equipped with such lids, but also, before capping, that of the lids on each other, finally on precise centering during installation.
  • the annular part of the cover is intended to be applied, by means of the seal with which it is fitted, against a corresponding portion, preferably conical, of the edge of the ring of the containers and very especially of glass containers. .
  • On this edge will also be provided a rim or external protective rod, the relief of which will be sufficient, thanks to the small, total thickness of the cover, to hide the periphery of the latter and prevent that, accidentally displaced from its seat, it may lose its seal.
  • the portion of the edge of the ring adjacent to the opening will include at least one sealing ring on which the seal of the cover will bear.
  • This sealing ring must be sufficiently narrow and naturally have a relief less than the thickness of the seal, therefore a fortiori than the outer edge of the ring, while the edge of the cover is preferably raised slightly, at a similar angle. from that formed by the top of the ring, to allow the collar to avoid the external protective ring while remaining protected by it with sufficient play.
  • the containers whose ring has the arrangements which have just been stated are within the scope of the present invention.
  • the container is closed in a known manner by injecting steam into the opening of the container and by placing the lid on the edge of the ring while hot.
  • atmospheric pressure hermetically applies the seal against the ring, without any manual intervention.
  • the seal under the effect of heat, deforms to conform to the shape of the ring while the sealing ring penetrates there, the cover thus disappearing in the housing formed by the outer edge of the ring; the latter effectively protects the cover against any involuntary stress and a seal of a few tenths of a millimeter is sufficient to obtain an effective closure.
  • closure device according to the invention due to the ease of deformation left to the cover by its quasi-flatness and the fact that the seal with which it is fitted deforms hot to conform to the shape of the part of the ring of the container on which it rests, admits for this ring manufacturing tolerances and mainly flatness much greater than what can accept existing closure devices. This constitutes an important advantage of the invention.
  • thermoplastic resin is poured onto the cover kept in rotation takes place inside the flange partially folded over the outer rim, said flange being then folded down completely and held in position using a matrix, which simultaneously forms said seal, until gelation of said resin.
  • the closure device according to the invention is in the form of a cover 1, which rests on the edge of the ring 2 of container 3 with large opening, without protruding outside of this ring.
  • the cover 1 consists of a metal disc of 0.2 mm sheet obtained simply by cutting and stamping. It has a flat central part 4, connected by a frustoconical shoulder 5 of about 3 mm to a flat annular surface 6 which bears on the upper edge of the ring 2, with the interposition of a seal 7 made of a thermoplastic material of a thickness of 0.3 to 0.4 mm, which adheres to the underside of the periphery.
  • This comprises an edge 8, having below it a flange 9 folded to double thickness, the edge 10 of which is in contact with the seal 7 which thus remains projecting at the bottom.
  • the edge of the ring 2 on which the cover 1 is supported by means of its seal 7 has an annular upper surface 11, flat in the present case, 2 to 3 mm wide, and bordered towards the outside of the container by a protective ring 12 forming a rim with a height of 0.6 mm and towards the opening of the container by a circular sealing ring 13 which here has a height of 0.2 mm.
  • the seal 7 is supported on the rod 13 and on the flat surface 11.
  • the establishment of the plugging device is carried out hot, so as to allow the joint 7 to deform by marrying the shape of the rod 13 and any roughness of the edge of the ring 2, after injection of steam in the container.
  • the condensation of this vapor inside the container causes a vacuum, under the effect of which the sealing device is applied hermetically around the opening of the container.
  • the rim 12 externally masks the edge 8 of the cover around its entire periphery with an average clearance of the order of 0.3 to 0.5 mm and effectively protects it against any effort liable to unintentionally take off the cover. of the container.
  • the edge 8 has been shown here slightly raised opposite the seal to be able to adapt more closely to the average profile of the ring. It is clear, however, that the peripheral part (6, 8) could be given slightly different shapes and for example place the flange 8 flat in the extension of the bearing surface 6 of the joint 7.
  • the fitting of the cover on the opening of the container can be carried out by any means known per se, for example using a magnetic head which, by means of the cone 5, makes it possible to obtain centering satisfactory from cover 1 on ring 2.
  • the cover 1 lends itself to stacking the containers on top of each other due to the frustoconical part 8. This part also facilitates handling and centering during operations for manufacturing the device and placing it on the container, without preventing very tight stacking which makes transportation very easy and economical.
  • the container can be stermed without any other precaution during this operation, except to operate in an autoclave whose pressure is higher than the saturated vapor pressure which corresponds to the sterilization temperature.
  • sterilization will be carried out at 120 ° C. under an autoclave pressure of the order of 2.5 to 3 atmospheres.
  • a protective belt 14 made of a retractable material, which matches the external shape of the ring 2 (FIG. 4). It is also possible to use for this purpose a molded cap 15, fitted on the ring 2. Such a lining has essentially a decorative role, but it also prevents fraudulent operations and also protects the edge of the container. Its use is, however, entirely optional, since the vacuum prevailing in the container is sufficient to rigidly hold in place the cover 1 on the ring 2, without risk of catching with external obstacles, due to the protective rim 12. It will be noted incidentally that, in this example, the surface 11 of the container is tapered towards the inside.
  • the closure device according to the invention adapts to rings having large manufacturing tolerances, which constitutes a considerable advantage compared to existing systems.
  • this device can be manufactured by simple and inexpensive means, using a technique known per se, the main phase of which is shown in FIG. 3 of the drawings.
  • thermoplastic resin 7a added with a crosslinking agent is poured on the cover 1 driven in rotation, the flange 9 disposed at the periphery is still folded only 120 ° relative to the edge 8.
  • the seal is then formed while folding the collar 9 using said matrix. This is kept in position, during the gelation of the thermoplastic material, then it is completed by pinching, to drown the edge 10 in the thickness of the joint which is thus projecting from the underside of the cover.
  • the invention therefore provides a simple, practical and inexpensive means for closing large-opening glass containers.
