Definitions

  • the invention relates to a container closure made of plastic from a closure part which can be connected to the container, with a membrane part consisting of one piece with it, which seals the pouring opening, and with a cap which can be releasably connected to the closure part.
  • Container closures with these features are known in order to keep a liquid container closed liquid-tight during storage.
  • the membrane part closing the pouring opening is then pierced or preferably torn out, after which the closure is then closed exclusively with the aid of the screw-on, plug-on or otherwise connectable to the lower closure part.
  • the containers consist of relatively thin-walled flexible materials such as tinplate or plastic, and these containers are immediately after filling, i.e. Before the contents are cooled, hermetically sealed, a vacuum is created inside the container during the cooling process, which can lead to deformation of the container shell (implosion, pannelling).
  • liquids have to be filled which have such an increased vapor pressure at elevated ambient temperatures, such as when storing in rooms with an elevated temperature, such as during the summer, that the said containers made of relatively thin-walled flexible materials also deform by re-forming bulge outside.
  • a container closure which ventilates or ventilates the container in the event of overpressure or underpressure, but only during venting or during storage creates a connection to the atmosphere, but is otherwise sealed gas-tight and liquid-tight.
  • a container closure should consist entirely of plastic and be as simple to manufacture as possible in terms of production technology. For this purpose, it should consist of as few individual parts as possible, so that as few spraying operations as possible are required in its manufacture.
  • the container closure according to the invention made of plastic for ventilating or venting a container and having the features mentioned at the outset is characterized in that the membrane part has an elastic membrane with an opening which, in the normal position, is closed in a gas-tight manner by a projection of the container closure abutting the opening, where the membrane is biased against the projection of the container closure, and a cavity of the cap adjacent to the opening is in open communication with the atmosphere.
  • the membrane Due to the fact that the membrane is biased against the projection of the container closure, the interior of the container remains liquid and gas-tight during storage. This is of particular importance if the product has a relatively high vapor pressure or is susceptible to oxidation.
  • the elastic membrane lifts under vacuum or overpressure in the container from the projection of the container closure, whereby the opening in the membrane for the gas passage is exposed and a loading - or venting the interior of the container until the internal pressure again matches the external pressure. At this point, the membrane rests against the protrusion of the container closure and thus closes the opening.
  • the opening is therefore only open for a very short time for ventilation and is sealed gas and liquid-tight during storage under normal conditions.
  • the opening can be kept very small, since only relative small amounts of gas must enter or exit the container through them.
  • the cap has an inner cavity directly adjacent to the opening, which is in open communication with the atmosphere via an air duct, so that when venting through the opening into the Cavity of the cap escaping air or steam can escape into the atmosphere through the air duct or air can be sucked in through the air duct when the membrane is lifted from the projection of the container closure.
  • the projection of the container closure can be connected to the cap and can have, for example, the shape of a pin which is connected in one piece to the cap and which extends from above to the membrane and in the normal position lies against it.
  • the opening is expediently provided in the center of the membrane and the pin in the center of the cap.
  • the projection may spur.Auch arranged eccentrically example, be formed annularly.
  • the projection closing the opening can be arranged on the lower closure part.
  • the membrane part can expediently have a web arranged diametrically on it with a pin attached to it, which, depending on the task, lies against the opening from above or from below. If it is from above, the container closure can be ventilated, if it is from below, it can be vented. The principle of operation is the same in both cases.
  • the person who closes the opening needs Projection not to be a pin, but can also be a rib or any other shaped part. With a pin with a rounded free end, however, you get a particularly effective seal, so that this training is preferred.
  • the open connection between the inner cavity of the cap and the atmosphere can be designed differently.
  • the cover part of the cap can have an opening.
  • the container closure according to the invention is intended to allow ventilation when filling goods with elevated temperature only after filling during cooling
  • the air channel between the cap and the lower closure part can be arranged such that it only then has an open connection to the atmosphere produces if the cap is not completely screwed on or is otherwise connected to the lower closure part, but then closes by a further partial rotation.
  • the membrane part causes a completely tight seal when the container is stored, it is irrelevant that at the same time there is no complete gas tightness between the cap and the lower seal part. If the membrane is then removed before use, the cap will be firmly screwed on when the container is reclosed, the latter then being closed in the latter arrangement and construction of the air duct, so that the gas tightness between the cap and the lower closure part is then produced.
  • the membrane part is preferably provided with weak points or with continuous material weakening on its entire outer circumference in a manner known per se, so that it can be removed as a whole. This is to make it easier to remove Provide the membrane part with a tear ring into which the index finger can be hooked in order to tear out the membrane part.
  • the membrane part itself can also be designed differently. So it can consist of the membrane. Appropriately, however, it has a substantially rigid web running all around and an elastic membrane surrounded by this web and consisting of one piece with it. The tear ring mentioned above is then attached to the web. Such a membrane part can be easily removed completely from the pouring opening by jerky tearing out.
  • the lower closure part can be connected to the container in a manner known per se, such as by snapping, screwing, welding, flanging the edge of the container or otherwise.
  • the cap can also be releasably attachable to the lower part of the closure in a different and known manner, such as by screwing, plugging, bayonet closure or the like.
  • Each of the container closures has a lower closure part 1 and a cap 2, each of which is made in one piece from a plastic material.
  • the lower closure part 1 has a membrane part 3, which in the case of the embodiment according to FIGS. 1 to 3 consists of an all-round, essentially rigid web 9, a tear ring 7 attached to it and an elastic membrane 4 surrounded by the essentially rigid web 9. All of these components of the membrane part are integrally connected to one another.
  • the membrane 4 has an opening 5 which, in the case of the embodiment according to FIGS. 1 to 3, is closed in the normal position by a pin 6 of the cap 2 rounded at the free end. Due to the flexibility of the membrane 4 and the height adjustment between it and the pen
  • the membrane 4 rests on the pin 6 with a certain pretension. If a negative pressure now arises inside the container, the membrane 4 is lifted from the pin 6 by the higher atmospheric pressure, air flows through the opening 5 into the interior of the container until pressure equalization between the atmospheric pressure and the pressure inside the container is achieved. Then the membrane 4 bears against the pin 6 again, whereby the opening 5 is closed again.
  • the connection between the opening 5 and the outside atmosphere is achieved by a small air channel 8 between the cap 2 and the lower closure part 1.
  • the inner cavity of the cap 2 adjoining the opening 5 has the reference number 10.
  • the wall of the container on which the container closure according to the invention has been placed is designated by 13.
  • the container closure shown in Figure 4 according to the invention for ventilation differs from that according to the Fi guren 1 to 3 in that in the cap no opening 5 closing pin is provided, but that the membrane part 3 in addition to the all-round web 9, the tear ring 7 and the membrane 4 with the central opening 5 one at the all-round web 9 has diametrically arranged web 11 fastened on both sides, such as, for example, welded on, glued on or locked in place, with a pin 12 fastened thereon in one piece.
  • the pin 12 abuts the opening 5 of the membrane 4 from below, so that in the event of an overpressure in the container, the membrane lifts upward from the pin and in this way vents the container.
  • the cap 2 is removed in conventional manner, such as unscrewing, and the diaphragm part 3 by means of the R 7 influencingringes torn out.
