Definitions

  • the invention relates to a method for producing a sealable seal, intended to allow the closure of a container with closure by cap or capsule. It also concerns sealable joints obtained by this process.
  • the role of the seal is first of all to confer an inviolability on the container before first opening. In addition, it seals container primary vis-à-vis the outside. In addition, he must develop certain compatibility properties with the content it is supposed to isolate from the outside, and for example be food grade when the content is food.
  • the support is intended to absorb the tolerances between the bottom of the capsule and / or cap and the upper part of the neck of the container, and in addition, to ensure secondary sealing, as soon as the cover has been opened or removed. It is therefore likely to ensure some compression with memory effect to precisely allow to absorb these tolerances.
  • the support is temporarily secured to the cover with a temporary bonding adhesive.
  • adhesive is well known for this application and is generally consisting of glue, or microcrystalline wax or other compounds likely to fulfill the same function.
  • sealable joints of the type in question are mainly of two types.
  • the first type is a joint without a tongue so that the cover is difficult to tear off or remove after its positioning at the upper edge of the container neck.
  • the invention proposes a type of seal that can be sealed in which only the cover is provided with a tear-off tab. It offers also a method for producing such a seal.
  • the invention consists in starting from a strip assembly likely to form the basis of sealable joints, to make first of all undergo a precut at the level of the only support strip, corresponding to the shape of the subsequent joints, then to remove, following this precuts the "skeleton", that is to say all the falls of the strip constituting the support, so as to obtain a striped strip consisting of a substantially rectangular strip corresponding to the strip within which the only lids are made, at the level of which appear the future supports of the joints according to their shape definitive, then proceed to cut the whole, directly above said joints, according to the desired shape of the lids, that is, by providing these with a tab.
  • the positioning of the strip ribbing at the cutting member takes place after centering pre-cut supports at the cutting member, this centering being advantageously carried out by means of a cell wedging, for example on the thickness of the support relative to the strip at within which the only lids are produced, this timing being effected advantageously at the level of the inter-support zones of the strip ragged.
  • This calibration can also be carried out in relation to the appearance of surface of the pre-cut support, or even at a level mark on the strip for this purpose.
  • the invention also relates to a sealable joint for sealing. of a container with closure by stopper or capsule, comprising a support intended to be positioned at the bottom of the stopper or the capsule and a operculum, temporarily secured to the support before putting it on in place within the cap, and at the lid of the container. It is characterized in that the cover comprises an extension intended to constitute the pull-out tab of the lid when the first opening of the container.
  • the joints thus produced, sealable and advantageously heat sealable can be used for many applications, especially in the food, cosmetic, chemical fields, pharmaceutical, etc., according to an easy implementation, while preserving the required inviolability conditions, further facilitated by uprooting easy to seal.
  • Figure 1 is a schematic plan view of a joint according to the invention.
  • Figure 2 is a cross-sectional view of Figure 1.
  • FIG. 3 is a schematic representation of a strip of the material of the seal obtained after assembly by adhesive with temporary connection of the support to the cover, of which FIG. 4 is a view in cross section.
  • Figure 5 is a view similar to Figure 3 after pre-cutting, of which Figure 6 is a cross-sectional view.
  • FIG. 7 is a view similar to FIGS. 3 and 5 after weeding
  • Figure 8 is a sectional view.
  • Figure 9 is a representation of the strip after cutting final of the cover, of which Figure 2 is a representation cross section.
  • Figure 10 is a schematic representation of an installation likely to carry out the weeding of the strip in accordance with the invention.
  • the seal bearing the general reference (1) in FIG. 1 is heat sealable by induction, i.e. it has at least one film made of a dielectric material, capable of transforming high frequency waves in thermal energy, to allow the rise in temperature of a thermo-plastic film associated with it, to allow its softening and sealing on the upper edge the neck of a container.
  • Such a seal (1) is in fact intended to allow the obturation and the tightness of a container, the closure of which is obtained by means a capsule or stopper, itself screwed or clipped at the neck of said container.
  • Such a sealable joint basically consists of two parts, namely respectively a support (5) and a cover (2), the support / cover assembly being temporarily secured by means temporary bonding adhesive (6) (see Figure 2).
  • the support (5) is intended to be inserted, in particular by force, at the bottom of the closure cap. As already said, it has a role in absorbing tolerances between the bottom of the capsule on the one hand and the upper part of the container neck on the other hand, and, is also intended to ensure a secondary tightness towards the outside, when the cover has been removed, i.e. after first use or first opening of said container.
  • This support with a typical thickness of between 0.5 and 4 mm, can be made of expanded polyethylene or another material compressible with recovery memory, possibly fitted on its two sides of a polypropylene or other film, in order to give it a some rigidity. It can also be made of cardboard, or even cardboard added with plastic foam, or be made of polystyrene, the examples thus indicated are in no way limiting but purely exemplary.
  • the cover basically comprises according to the invention a tongue (4) extending it, intended to allow the tearing off of said seal when the container is used for the first time is sealed.
  • This seal which is therefore sealed and in particular heat-sealed on the upper edge of the container neck is primarily intended to ensure the inviolability of the contents of the container.
  • it also provides a primary seal as long as said container was not opened for the first time.
  • This cover must also be compatible, either with the content of the container, especially when it is food, either with the container itself, depending on whether it is made of glass, or of material plastic.
  • this joint also includes a film made of a material dielectric for transforming high frequency waves (typically 20 kilohertz) that it receives in thermal energy, intended for soften the plastic film, positioned on its face in manhole cover to allow sealing.
  • a film made of a material dielectric for transforming high frequency waves (typically 20 kilohertz) that it receives in thermal energy, intended for soften the plastic film, positioned on its face in manhole cover to allow sealing.
  • high frequency waves typically 20 kilohertz
  • the support (5) and the cover (2) are temporarily joined between them in particular either by means of a film, a mesh or dots of temporary bonding adhesive (6), such as glue natural or synthetic, either with micro-crystalline wax advantageously positioned punctually according to a multitude of points, almost uniformly distributed.
  • This micro-crystalline wax is advantageously absorbed during heat sealing in a thin film of paper or cardboard respectively associated either with the support (5) or with the cover (2), taking into account its liquefaction.
  • a strip of a material intended to constitute the support is first made, for example by extrusion of low density polyethylene, followed an expansion thereof and laminating two polypropylene films, said strip then being stored in the form of a reel.
  • a strip of a material intended to constitute the cover is produced by assembling a thermo-plastic film intended to allow subsequent sealing, possibly associated with a film aluminum (9) or even an additional sheet of cardboard paper, intended to absorb the temporary bonding adhesive during heat sealing.
  • the constituent complex of the lid can also include a film of parchment paper or equivalent. This tape is also advantageously stored in the form of a reel.
  • the two coils are routed to an installation in known itself, intended to allow reversible and temporary joining of the two bands.
  • the two strips Prior to their assembly, the two strips are cut to the same width, in order to minimize the losses in falls, in order to adapt them to the working formats of the cutting used in the rest of the process.
  • the bands as well cut-outs may contain one or more joints in width, depending on their dimensions.
  • the two bands are joined together using an adhesive to temporary bonding, typically glue or micro-crystalline wax, the latter being positioned on the support strip and / or the cover strip, the two strips then being assembled by calendering, the thermoplastic film sealing formed on one of the faces of the seal strip being directed outwards.
  • an adhesive to temporary bonding typically glue or micro-crystalline wax
  • a strip (7) shown in FIG. 3 is thus obtained and in section in Figure 4.
  • This strip (7) is then routed at a cutting tool, typically consisting of a cookie cutter, intended for make pre-cuts (8) (see figure 5), corresponding to the shape and the dimension of the support (5) of the final joint.
  • a cutting tool typically consisting of a cookie cutter
  • pre-cuts (8) see figure 5
  • These precuts (8), as well that can be seen in Figure 6, are limited to the single support and do not affect the strip (9), that the cutting tool comes outcrop.
  • the strip (7) thus produced and provided with these precuts (8) is routed to a facility (16) called weeding, and materialized in FIG. 10, intended to make it possible to remove from said strip the "skeleton" (12) ie the periphery of the supports (5) defined by the pre-cuts (8), so as to obtain a striped strip (11) shown in Figure 7.
  • This installation (16) firstly comprises a first roller at which the strip (7) fitted with its precuts (8) is mounted, then a second roller (15) at which the skeleton (12) is wound, and finally a third roller (14) at which the ribbed strip (11) is wound, the position materialized by the letter A corresponding to the ideal position for removing the circumference or skeleton (12), the position materialized by the letter B being the limit position for removal of said skeleton, beyond which the removal of said skeleton is no longer carried out under good conditions.
  • weeding i.e. the removal of the skeleton (12) is done manually, then, once the roller (15) has started, it takes place automatically, speed and tension being adjusted of course, programmable.
  • the strip (11) thus ragged is then routed at a another cutting member, typically of the punch-die type, or a another cookie cutter, intended to produce, directly above the supports (5) the cutting of the single cover strip (9), i.e. corresponding substantially the same shape and size as the supports (5) but further comprising cutting the tongue (4), and this in the extension of the cover itself.
  • a another cutting member typically of the punch-die type, or a another cookie cutter, intended to produce, directly above the supports (5) the cutting of the single cover strip (9), i.e. corresponding substantially the same shape and size as the supports (5) but further comprising cutting the tongue (4), and this in the extension of the cover itself.
  • This cutting is carried out after prior centering of the cutting at the level of the supports (5) already cut, for example by means of a photoelectric cell detecting the variation in thickness in the inter-support zone with respect to the strip (9).
  • Cutting the shape of the cover may slightly exceed the dimension of the support, thus materializing a coplanar crown (3) with the cover (2) itself, which may further possibly facilitate the sealing operation. However, it may correspond to the support dimension.
  • the seal is placed directly at the level of the capsule during its cutting, the cutting member being in this case provided a piston, ensuring the positioning of the seal made at the bottom of said capsule.
  • the joint obtained turns out to be easier to install, since no tab has to be positioned at the bottom of the capsule plugging, and also allows the cap to be torn off also much easier.
