Definitions

  • the present invention relates to a container with a plastic closure which is non-removably attached to the fuselage, the lid having a closure part with a weakening groove which is connected to a joint and has a tab which is produced in one piece with the closure part.
  • Such a container is known from US-A-4 253 582, which is designed there as a so-called “easy open” container. Naturally, great importance is attached to easy opening and there is no thought of reclosing the lid.
  • the lid and the fuselage are manufactured separately and the upper edge of the fuselage is crimped around the lid.
  • a container is known in which the lid with the zipper is made in one piece with the body.
  • the upper part of this container is very tapered and has a relatively small opening, so that the filling is relatively complex, because for this purpose the container upside down, respectively. must be placed on the closure part.
  • the closure consists of a spiral part with a flap and cannot be closed again.
  • a container 1 can be seen in FIG. 1, consisting of a cylindrical body 2, a cover 3 produced in one piece therewith and a base 4 fastened after the container has been filled in.
  • the base is sealed and flanged.
  • the cover 3 has a circumferential collar 5 which has an incision 6.
  • a tab 10 is arranged within the part formed by the weakening crack and the joint, the entire cover with the opening part together with the body being made in one piece from plastic.
  • holding cams 11 are attached on both sides of the incision, under which the tab can be snapped.
  • the tab has ribs 12.
  • the filled containers can be stacked, the edge 13 of the base fitting around the circumferential collar 5.
  • the opening of the container can be seen from FIG.
  • the tab is released from the holder and raised, after which a pull can be exerted on it to tear open the opening part at the weakening gaps. It can also be advantageous to perform shear movements with the tab for opening. It goes without saying that the joint 7 is designed in such a way that it is not also torn off when it is torn open. Depending on the intended use and the content of the container, the incision 6 can serve as a spout. After use, the opening part can be closed again by latching the tab 10 under the cams 11.
  • the closure part 7 can be of any design and can also comprise the entire closure or cover, the weakening crack running around the entire closure. If the entire closure is removed and the can is to be reusable, it is advisable to provide it with a closure cap.
  • the tab 10 is made in one piece with the closure from plastic, and this closure has at least one weakening crack.
  • the fuselage 14 is frustoconical and tapers upwards.
  • the fuselage and the lid 3, or closure are injection-molded in one piece from plastic and have, for example, the same elements as the container of the first exemplary embodiment.
  • these containers can be stacked empty, with the tab 10 arranged as it comes from manufacture, i. H. vertically upwards so that one container after the other can be easily removed from the stack by the tab.
  • the taper of the fuselage is selected such that the tab is not pressed in in the vertical state. In the filled state, the container base is supported again on the collar 5 of the cover part.
  • the fuselage 2 is cylindrical as in the first example according to FIG. 1 and has the same base 14 with an edge 13 which fits around the collar 24 of the cover 15.
  • the upwardly tapering collar has an incision 19 which is a little narrower than the width of the tab 20 in order to achieve a clamping effect.
  • the tab 20 is provided with a hole 21 which fits a pin 22 which is arranged on the cover. This allows the tab to be attached during manufacture so that it does not protrude from the container and does not interfere with the filling process. It is also possible to provide a different type of fastening in order to hold the tab on the cover, for example by welding at one point.
  • the tab is arranged near the weakening crack 17 of the closure part 16, at the incision 19, in order to ensure the greatest possible transmission of force when opening.
  • This weakening crack extends over a substantial part of the circumference, that is to say over at least three quarters thereof, and is connected via a joint 18 which is arranged near the opposite end.
  • a joint 18 which is arranged near the opposite end.
  • Containers with the inventive features need not only be cylindrical or conical. They can also be oval or rectangular containers and those whose walls taper slightly upwards.
  • All such containers according to the invention have in common that, with the exception of the base, they can be sprayed in one piece economically and that they can be easily filled and closed on existing systems. With a suitable dimensioning of the lid, the opening part can be opened and closed easily.
