Definitions

  • the present invention relates to a container having a neck closed by a rectangular lid and a tip for heat sealing a cover.
  • the strip of plastic material forming the cover rectangular is preferably arranged asymmetrically so that it does not overflow significantly that on one side of the neck which delimits points of large dimension while on the opposite side of the neck the edge of the cover is flush with the edge of the neck so that it only delimits small spikes.
  • a container of the type above in which the small spikes are folded down along the neck and fixed to it.
  • small points are fixed by heat sealing.
  • fixing small spikes can be carried out at the same time as fixing the cover on the neck of the container.
  • the small points are heat sealed in segments extending parallel to an edge of the neck.
  • the segments create a hinge for the cover when it is raised, which facilitates the manipulation of the cover.
  • heat seal tip with one side plan of heat sealing of a cover on the neck of a plastic container.
  • the heat seal tip also has a folding finger for folding a tab of the cover without soldering this tab to container.
  • the heat sealing tip has protruding heat sealing wings relative to the heat sealing face on the sides of this one.
  • the heat sealing wings have an edge of inclined attack, preferably at 45 °. So when the heat seal tip is in the standby position above from the neck of a container, just bring laterally a segment of strip intended to form the cover so that this is automatically deflected down so only by a very short stroke of the heat-sealing tip the heat sealing face is in contact with the upper side of the cover while the wings come simultaneously in contact with small spikes of the cover.
  • the wings are inclined towards the inside of the face heat sealing. So the wings of the heat seal tip don't lean on the tips of small dimension only by an edge and we get a weld specifies small tips of the lid.
  • the container is a container made of plastic 1 comprising a neck fitted with a pitch of screws 2 and having an edge 3 delimiting an orifice of the container which is closed with a rectangular lid heat-sealed 4 cantilevered from the edge from neck 3 to delimit therewith points of large dimension 5 and small points 6.
  • the tips of small dimension 6 of which only one is visible in FIG. 1 are folded down along the neck of the container and fixed to it, for example by heat sealing in a segment 7 which extends parallel to the edge 3 of the neck and thus forms a hinge for cover 4 when it is lifted by pulling on one of the large spikes 5.
  • fixing small spikes on the sides of the neck of the container 1 tends to reduce elastic way the cover 4 on the edge 3 of the neck of the container which naturally protects the product remaining in the container after opening.
  • a nozzle heat sealing generally designated in 8.
  • the end cap heat sealing 8 has a generally cylindrical shape and has a circular planar heat sealing face 9 turned down.
  • the heat sealing tip 8 further comprises wings 10 which extend in projection relative to the heat-sealing face 9 on the sides of it by being inclined towards the inside of the heat sealing face so that the bottom edges 11 wings 10 extend parallel to the heat sealing face 9 while being slightly turned towards the inside of the heat sealing face.
  • the edges 11 wings 10 automatically weld the tips of small dimension 6 in segments 7 on the side of the neck of container 1 as seen in connection with the figure 1.
  • the wings 10 have an inclined leading edge 12, preferably at 45 ° as illustrated in Figure 3, so that when band segment forming a cover 4 is advanced under the heat sealing face 9 towards the wings 10, as illustrated by an arrow in thick line in Figure 3, the points of small dimension 6 are automatically folded down down through the leading edge 12 and so are prepositioned in relation to the neck of the container.
  • a short stroke of the heat sealing tip 8 allows fix the cover at the same time on the edge 3 of the container and ensure simultaneous attachment of small spikes size 6 on the sides of the container neck.
