Definitions

  • the invention relates to the field of sealable seals, more particularly intended to allow the closure of a closure container by cap or capsule. It relates more particularly to the method of producing such a sealable seal.
  • the closure of a number of containers, especially in the food field is achieved by the implementation of a cap or a capsule. However, prior to the first opening of said container, it is closed by means of a seal thermally sealed on the rim or upper rim of the neck of the container, so as to protect its contents, including moisture. This seal can also be glued on said rim.
  • a sealable seal has been developed consisting on the one hand of a support, generally having a relative thickness, intended to be inserted into the bottom of the stopper or of the capsule, and on the other hand, of an integral seal. at least temporarily to said medium.
  • the role of the lid is to ensure the primary seal of the container vis-à-vis the outside. It also allows to confer inviolability to the container before its first opening, and thus guarantee the consumer the quality of the product it acquires.
  • the operculum must be compatible with the content that it is supposed to isolate from the outside and also have food qualities when the content is actually food.
  • a cap is made of aluminum supplemented with a sealing layer.
  • this sealing layer may be made of polyethylene, polypropylene, paper or other sealant coating deposited on the aluminum.
  • This lid is optionally supplemented with a mechanical reinforcing layer, consisting of polyethylene or polyester.
  • the support is designed to absorb the tolerances between the bottom of the cap or capsule and the upper part of the neck of the container. It also ensures the secondary seal, that is to say the seal that must provide said cap after removal of the lid, that is to say after first opening of the container.
  • This support is for example made of cardboard or expanded polyolefin. It may be monocomponent or composite, and in this case, for example consist of a sandwich of a polyethylene foam expanded between two layers of polypropylene, depending on the characteristics that it is desired to confer on said support. It can also be simply constituted of a layer of expanded polypropylene.
  • the support also ensures a pressure on the lid to ensure the correct sealing thereof when effectively closing the container after filling.
  • the objective of the present invention is precisely to avoid this risk of delamination of the sealable seal, and at the same time simplify as much as possible this process, in particular by deleting a step.
  • the invention therefore relates to a method for producing a sealable seal, intended to seal a closure container cap or capsule, said seal comprising a sealing cap provided with a tear tab secured temporarily to a support.
  • the invention consists in arranging within the support strip a cutout or preliminary light, in the entire thickness of said strip, and corresponding to little more closely to the shape of the single pulling tab. and therefore, adjacent to the generally circular profile of the shape of the joint, then, to achieve after joining of the two bands suitable for constituting the complex constituting the sealable seal of the invention, a cutout of the entirety of this complex, that is to say, support tape + sealing strip according to the exact profile or the exact contour of the cover, ie a circular shape to which is added the tab.
  • the cutting member ensuring the realization of the final shape of the joint, that is to say after joining the two strips respectively support and operculum, initiates the cutting side support strip, allow to avoid the slight flap of the operculum on the support that may occur if the primer intervened on the opposite side.
  • the support strip is provided with identifiable indicia by photoelectric cells, these indices possibly consisting of a through-light produced in the support, or by printing a mark also detectable by photocells.
  • This seal 1 basically consists of a support layer 5, typically made of expanded polypropylene, or a polypropylene / expanded polyethylene / polypropylene sandwich. It has a typical thickness of between 1.5 and 1.7 mm.
  • This support 5 is associated with a cover 2, typically made of aluminum, the dimensions of which correspond to those of the support 5, with the exception of an extension 4 forming the tear-off tab, this cover being associated with a film sealer.
  • the fastening of the support 5 to the cover 2 can be achieved by any means such as in particular the implementation of a temporary bonded adhesive.
  • a temporary bonded adhesive This is for example made of a polymer based on polyethylene, obtained by extrusion.
  • the support 5 is traditionally in the form of a ready-to-use reel.
  • This coil consists of a strip passing in front of a cutting member, ensuring the realization of a through-light within the support strip, of surface 7 slightly greater than the surface corresponding to that of the pull tab of the operculum intended to be secured to this support.
  • This cutting member can also be multiposte, the cutting operation of said light can be performed simultaneously for several joints in a single operation.
  • a support strip is obtained having a plurality of cuts corresponding to this surface 7, greater than that of the tab of the future seal.
  • the next step is then to provide a second cut 8 by means of a suitable cutting member over the entire thickness of the assembly of the two strips respectively support and operculum thus produced, and according to the shape of the opercule provided with its tongue, that is to say a circular shape provided with a tongue.
  • the cutting member providing this function is arranged in such a way that, of course, the particular cut of the tongue 4 is located in line with the pre-cut area 7 of the support 5 in particular. Figures 3 and 4 . In doing so, effective cutting of the seal according to its final form takes place in a single operation, the cutting members providing no effective cutting function at said previously made lights.
  • the cutting member initiates its cutting on the support side 5, so that the cutting edge of the cutting member does not induce any folding of the lid on the edges of the support, but is more likely to push said seal in the direction of the outside and in this case of the bottom on the Figures 5 and 6 .
  • the cutting member is of the punch type, that is to say that it cooperates with an anvil (not shown) to ensure the effectiveness of cutting.
  • the support strip 5 is provided with indexing indicia 9, detectable by photocell and allowing the device for advancing the entire band support / band operculum to be correctly positioned in line with these cutting members.
  • indexing indicia 9 detectable by photocell and allowing the device for advancing the entire band support / band operculum to be correctly positioned in line with these cutting members.
  • These registration marks may consist of through-holes formed within the support strip 5, and made during the cutting of the lights 7. They can also be simply printed during the first cutting operation.
  • sealable seals are obtained according to the requirements of the users.
