Definitions

  • the present invention relates to a cover for closing by heat-sealing a container comprising a sealing zone of thermoplastic material delimited by an internal closed line and an external closed line, of the type comprising a sealing material, a varnish applied to the one of the faces of the sealing material, and an attached layer of thermoplastic material fixed in a separable manner on the sealing material and covering at least the part of the varnish which is intended to face the sealing zone of the container to be closed, as well as a process for manufacturing such a seal.
  • the present invention proposes more particularly to remedy this drawback and, to do this, it relates to a cover of the aforementioned type which is characterized in that the added layer has a thickness of the order of 100 to 1000 ⁇ (10 ⁇ 4 to 10 ⁇ 3 m), its thickness being chosen so that the thermoplastic material constituting it can, by locally melting when the container is closed by heat-sealing, encapsulate the traces of product reaching the sealing zone when the container is filled .
  • thermosealing of a container with the lid according to the invention can be carried out in a perfectly sealed manner.
  • the added layer and the sealing zone are both made of thermoplastic material, the latter, by melting locally under the effect of heat, encapsulates the traces of the product which are on the sealing zone and avoids therefore, at these traces, the formation of micro-channels which would promote the appearance of leaks.
  • the thermoplastic material forming the attached layer has a thickness of the order of 0.1 to 10 times the thickness of the sealing zone of the container. It is preferably the same as that forming the sealing zone of the container. It can for example be chosen from the group comprising polyvinyl chloride, polyethylene and polypropylene and have a thickness of the order of 100 to 1000 ⁇ (10 ⁇ 4 to 10 ⁇ 3 m). It can also be fixed on the sealing material with a varnish having a thickness of the order of 10 to 20 ⁇ (10 ⁇ 5 to 2.10 ⁇ 5 m).
  • the sealing material has a thickness of the order of 20 to 100 ⁇ (2.10 ⁇ 5 to 10 ⁇ 4 m) and can comprise at least one sheet of thermoplastic material and / or at least one metallic sheet.
  • the added layer covers the entire face of the sealing material which is intended to be turned towards the container and is precut along a line corresponding substantially to the internal closed line of the zone sealing the container.
  • the added layer can thus be torn along its precut line when the container is opened, its part located inside the internal closed line remaining integral with the sealing material.
  • the present invention also proposes to reduce as much as possible the production costs of the seal described above. To do this, it relates to a manufacturing process which is characterized in that it consists successively in producing in a strip of thermoplastic material a first series of openings whose periphery corresponds substantially to the closed line internally delimiting the area of sealing of the containers, fixing a strip of sealing material on the strip of thermoplastic material comprising the first series of openings, and making a second series of openings in the complex thus obtained whose periphery corresponds substantially to the closed line externally delimiting the sealing zone of the containers, the openings of the second series being produced in such a way that the openings of the first series are closed by the sealing material.
  • this process can consist successively of depositing against the bottom of a lower molding shell an element of sealing material whose dimensions correspond to those of the seal to be produced, to be applied against the lidding material element an upper molding shell having on its face turned towards said lidding material element a groove having an inlet whose dimensions correspond to those of the insert, to inject a thermoplastic material into the throat the upper molding shell to make the added layer, removing the upper molding shell after the setting of the thermoplastic material, and extracting the lower molding shell the cover thus produced.
  • the method of the invention may consist in producing the added layer by molding, preferably by injection, and in fixing on it an element of sealing material whose dimensions correspond to those of l seal to be made.
  • the present invention provides a process consisting successively of producing a series of thermoplastic material pre-cuts whose outline corresponds substantially to the closed line internally delimiting the sealing area of the containers, to fix a strip of sealing material on the strip of thermoplastic material comprising the pre-cuts, and to make in the complex thus obtained a series of openings whose periphery corresponds substantially to the closed line externally delimiting the sealing area of the containers, the openings being made so that the precuts are covered by the sealing material.
  • the container which can be seen in FIG. 1 comprises a peripheral rim 1 surrounding its inlet and is coated internally with a layer of thermoplastic material 2 extending over the peripheral rim 1 to form a sealing zone 3. It will be noted here that this zone can have a thickness of the order of 10 to 10,000 ⁇ (10 ⁇ 5 to 10 ⁇ 2 m).
  • This container which is entirely conventional, is closed by a cover 4 comprising a sealing material 5 bearing on its part overhanging the sealing zone 3 an attached layer 6 of thermoplastic material.
  • the attached layer 6 is fixed in a separable manner on the sealing material 5, by a varnish 7 having a thickness of the order of 10 to 20 ⁇ (10 ⁇ 5 to 2.10 ⁇ 5 m).
  • a varnish 7 having a thickness of the order of 10 to 20 ⁇ (10 ⁇ 5 to 2.10 ⁇ 5 m).
  • It can for example be made of polyvinyl chloride, polyethylene or polypropylene, the thermoplastic material constituting it being able or not to be the same as that used to form the sealing zone 3. Its thickness can moreover be between 100 and 1000 ⁇ (10 ⁇ 4 to 10 ⁇ 3 m).
  • the sealing material 5 can consist of a complex comprising at least one sheet of thermoplastic material and / or at least one sheet of aluminum and having a thickness of the order of 20 to 100 ⁇ (2.10 ⁇ 5 at 10 ⁇ 4 m).
  • the applied layer 6 of the seal 4 is applied to the sealing zone 3 of the container and the applied layer 6 and the sealing zone 3 are heated in order to make them melt with on either side of their contact surface and thus achieve their welding.
  • the thicknesses of the layer 6 and of the sealing zone 3 are significantly greater than that of the traces, possibly present on said sealing zone 3, of the product contained in the container.
  • heating of the added layer 6 and of the sealing zone 3 can advantageously be carried out by ultrasound.
  • the container that can be seen in Figure 2 is entirely of thermoplastic material and has a thickness of the order of 100 to 10,000 ⁇ (10 ⁇ 4 to 10 ⁇ 2 m). It comprises a peripheral rim forming a sealing zone 11 around its entry and is closed by a cover 12 in turn comprising an attached layer 13 fixed to a sealing material 14 by a layer of varnish 15.
  • the cover 12 is distinguished from cover 4 which has been described above only by the fact that the added layer 13 completely covers the face of the cover material 14 which faces the container, and is precut along a line 16 adjacent to the internal periphery of the sealing zone 11.
  • the installation visible in FIG. 3 has been developed to manufacture the cover 4 in series. It comprises a spindle 20 for receiving a coil 21 obtained by winding a strip of thermoplastic material 22 intended to form the added layer 6 of the lids 4, a cutting station 23 for producing in the strip 22 a succession of openings 24 whose dimensions correspond substantially to those of the opening of the containers to be closed, a pin 25 for receiving a coil 26 obtained by winding a strip 27 of sealing material, a sealing station 28 for fixing the perforated strip against one another 22 and the strip 27, a cutting station 29 for producing the lids 4 by producing in the strips 22 and 27, concentrically with the openings 24, a succession of openings 30 whose dimensions correspond substantially to those of the outer periphery of the rim 1 containers to be closed, a spindle 31 for winding up the strips 22 and 27 as they exit from the cutting station 29, and control means not shown for rotating the spindles 20, 2 5 and 30 in synchronism in the direction allowing the bands 22 and 27 to move in the same direction.
  • FIG. 3 could also, with slight modifications, be used to manufacture the cover 12 in series. It would indeed suffice to replace the cutting station 23 with a precut station capable of producing in the strip 22 precuts 16 whose contours would correspond substantially to that of the opening of the containers to be closed.
  • the mold visible in FIG. 4 has also been developed to manufacture the cover 4 in series. It comprises a lower shell 40 comprising a cavity 41 whose dimensions of the bottom are slightly greater than those of a cover 4, and an upper shell 42 shaped to penetrate with little play in the cavity 41, the shell 42 comprising on its face lower an annular groove 43 connected to channels 44 capable of injecting a thermoplastic material therein, the groove 43 having an inlet whose dimensions are substantially the same as those of the rim 1 of the containers to be closed.
  • the procedure is as follows: . is deposited on the bottom of the cavity 41 of the lower shell 40 an element of sealing material 45 whose dimensions correspond to those of the seal 4; . the upper shell 42 is applied against the element of sealing material 45; . a thermoplastic material is injected into the groove 43 of the upper shell 42 in order to produce the added layer 6 of the cover 4; . the upper shell 42 is extracted from the cavity 41 of the lower shell 40 after the thermoplastic material has set; and . the cover 4 thus produced is extracted from the lower shell 40.
  • cover 4 could be produced by first producing the added layer 6 by molding, for example by injection, then by fixing on said added layer an element of sealing material whose dimensions correspond to those of cover 4.
