Definitions

  • the invention relates to a reclosable container made of synthetic material with a delamination cover, in particular for condensed milk or coffee cream.
  • Patent EP 137 997 already relates to such a container, comprising a gripping part and a discharge opening.
  • This type of container is intended to be emptied in several stages.
  • the disadvantage of this type of packaging is that it does not have a reclosing system, which means that during the second use, a crust of milk is formed on the discharge opening which is on the one hand unsightly and on the other hand can cause risks of contamination of milk.
  • US Patent 3,101,870 relates to a resealable container which has a rim welded to a cover, said rim having to be torn during the first opening by means of weakening grooves.
  • DE-OS patent 3,446,093 relates to a container based on the same principle as the previous one, in which it is also necessary to tear the opening tab during the first opening. This type of opening requires a high opening force which can lead the user to handling faults which can lead to the contents being overturned.
  • the present invention makes it possible to remedy this type of defect by means of a reclosing system at will, in which the opening tongue is almost completely cut beforehand.
  • the invention relates to a resealable container made of synthetic material with delamination cap, in particular for condensed milk or coffee cream, comprising a bottom, a side edge and an upper rim for the filling and opening of the delamination cap, said container being substantially of cylindrical shape or conical trunk and comprising a gripping part and a pouring spout for the liquid on the lateral edge.
  • V-shaped opening tongue cut out on the upper rim along the contour of the edge of the pouring spout, said tongue being able to be placed in the container opening and closing position and the lid is welded on all the periphery of the upper rim, in particular in the region of the spout, on either side of the contour of the edge of said spout.
  • the cover must be welded on the opening tongue and on the inside of the rim of the pouring spout to ensure a front seal opening.
  • this type of packaging can also be used for packaging milk, cream, sauces, toppings and other liquid products from the food industry. It is very convenient to use, because it suffices, during the first use, to pull the opening tab, so that the seal comes off the inner upper rim of the part around the spout while remaining welded to the opening tab and all the rest of the periphery of the container. After use, fold the tongue over the spout.
  • a reinforcement zone extending along the edge of the pouring spout of approximately 5 to 40 mm.
  • This reinforcement preferably has a U-shaped section and it also makes it possible to better guarantee sealing during reclosing.
  • the container without lid is produced either by thermoforming or by injection.
  • the tear-off tab is an integral part of the upper edge. It is simply cut following the outline of the spout.
  • This cut is preferably at an angle, to allow when closing the tab a snap ensuring a good seal.
  • the opening tongue is not cut at the end of the branches of the V.
  • the tongue is advantageously notched under the rim and towards the outside of said rim to allow during opening a good hinge effect, so that the container remains open when in use.
  • the cover comprises an unwelded zone on the opening tongue between the welding zones on either side of the contour of the edge of the pouring spout.
  • the walls of the spout make an angle between 60 and 95 °, preferably an angle of about 92 °.
  • the material used for the body of the container is chosen from polypropylene, polyethylene, polyester, polyamide, polycarbonate and polyvinyl chloride, in the case where the container with its contents is thermized, for example by post-sterilization.
  • This container is either single-layer or multi-layer in which case the combination of polypropylene / EVOH / polypropylene can be envisaged.
  • the EVOH layer copolymer of ethylene and of vinyl alcohol
  • the delamination cover is normally an aluminum foil sealed on the upper rim of the container by welding.
  • Other covers are also possible, eg. made of plastic materials, such as polyvinyl chloride.
  • embossed lid To avoid cracking of the lid in case of post sterilization, we choose an embossed lid.
  • the container comprises a bottom (1), a side wall (2) and an upper rim (3). On the side wall, there is the spout (4) and the gripping part (5).
  • the delamination cover (6) is welded to the flange (3) which includes in the region of the spout a tongue opening (7).
  • This tongue has a reinforcement zone (8) of substantially U-shaped section and is cut from the upper rim along the line (9) defining the contour of the edge of the spout. This cut is normally at an angle as shown in Fig. 3.
  • the procedure is as follows for the manufacture of this container. Thermoforming is carried out to obtain the shape according to FIG. 4. We cut along the line (9). The container is sterilized and brought to an aseptic filling machine where filling is carried out, for example with condensed milk. Finally, the delamination cover (6) is welded to the upper rim (3). The cover must be well welded on the area (a) (Fig. 2) and on the opening tab (7). Zone (a) must have a width of at least 1 mm to guarantee a good seal of the pot. We thus have a jar of long-life product ready for consumption.
  • the container with its contents is transferred to a sterilization installation.
  • the welding of the cover on the entire upper edge (3) must be of very good quality in order to resist the sterilization conditions.
  • the width of the weld bead should be approximately 2 mm. In the area of the spout, the welding width is approximately 2 mm on either side of the line (9).
  • the tongue (7) is folded forward. It clicks into place with its edge (10) on the edge (11) of the spout.
  • the angle forming the spout is approximately 92 °.
  • edge (10) relative to the edge (11) is obtained by the hinge function of the part (12) (Fig. 5) not cut from the flange (3).
  • a notch (13) is provided at this point under the upper rim (3) and towards the outside of said rim allowing good opening when the container is used to pour the contents.
  • the welded area of the cover on the upper edge is indicated by hatching in fig. 2.
  • zone (14) for non-welding of the cover.
  • zone (12) the welding strip must be wide enough to guarantee a good bonding of the seal at the place which serves as a hinge for successive openings / closings.
  • the jar of cream according to the invention is normally designed to have a capacity of 120 to 200 ml.
