Definitions

  • the invention relates to a container closure made of plastic, consisting of a lower closure part which can be connected to the container, a membrane part which consists of one piece, closes the pouring opening, can be torn out and has an elastic membrane, and a cap which can be releasably connected to the lower closure part.
  • a container closure with these features is known for example from EP-A-82 757, it serves the purpose of keeping a liquid container closed in a liquid-tight manner during storage.
  • the membrane part closing the pouring opening is then pierced or preferably torn out, as in the container closure known from EP-A-82 757, after which the closure then takes place exclusively with the aid of the screw-on, attachable or otherwise connectable cap to the lower closure part.
  • liquid filling goods that are filled at elevated temperatures for production reasons.
  • the containers are made of relatively thin-walled flexible materials, such as tinplate or plastic, and if these containers are hermetically sealed immediately after filling, i.e. before the contents are cooled, a vacuum is created inside the container during the cooling process can lead to deformation of the container shell (implosion, pannelling).
  • liquids have to be filled which, at elevated ambient temperatures, such as when stored in rooms with an elevated temperature, for example during summer time, have such an increased vapor pressure that the said containers made of relatively thin-walled flexible materials also deform by becoming bulge outside.
  • both the one-way valve and the vent valve have a membrane part which is designed as a relatively hard, flexible plastic disk, with a conical section which encloses a central opening which interacts with a sealing pin, the sealing surfaces of the sealing pin and the adjacent membrane part as flat surfaces are formed.
  • 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 necessary in its manufacture.
  • the container closure is characterized in that the elastic membrane has an opening for ventilating or venting the container, which in the normal position of the membrane part is airtightly closed by a pin of the container closure resting on the opening and rounded off at its free end , wherein the membrane of the membrane part rests with pretension against the pin of the container closure, and a cavity of the cap adjacent to the opening is in open communication with the atmosphere.
  • the membrane of the membrane part rests with prestress against the pin of the container closure, the interior of the container remains liquid and gas-tight during storage, the formation of the pin with the free rounded end being particularly effective Seal guaranteed.
  • the elastic membrane lifts under vacuum or overpressure in the container from the pin of the container closure, whereby the opening in the membrane for the gas passage is exposed and a loading or venting the inside of the container until the internal pressure again matches the external pressure.
  • the opening is therefore only opened for a very short time for ventilation and is closed in a gas-tight and liquid-tight manner during storage under normal conditions.
  • the opening can be kept very small since only relatively small amounts of gas have to enter or exit the container through it.
  • Venting or venting can function despite the cap connected to the lower closure part, the cap has a cavity directly adjacent to the opening, which is in open communication with the atmosphere, so that air or steam escaping through the opening into the cavity of the cap when venting can escape into the atmosphere or air can be sucked in during ventilation if the membrane is lifted off the pin of the container closure.
  • the open connection of the cavity of the cap with the atmosphere can be designed differently.
  • the cover part of the cap can have an opening.
  • 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. Since 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 pin of the container closure can be connected to the cap, for example in the case of an integral connection therewith, and rest against the opening from above.
  • the opening is expediently provided in the center of the membrane and the pin in the center of the cap. In the same way, however, the opening and pin could also be arranged off-center.
  • the pin which closes the opening can be fastened to the pull-out membrane part via a substantially rigid connecting part and can rest against the opening from above or below.
  • the membrane part can expediently have a web arranged diametrically on it with the pin attached to it. If this lies against the opening from above, the container closure can be ventilated; if it lies from below, it can be vented. The principle of operation is the same in both cases.
  • 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 is easily removable overall.
  • the membrane part is provided 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 made 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 part of the closure 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.
  • FIGS. 1 to 3 on the one hand and FIG. 4 on the other hand with the same design and the same reference numbers.
  • Each of the container closures has in the 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 one of which in the essentially rigid web 9 surrounding elastic membrane 4 there. 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 pin 6, the membrane 4 rests on the pin 6 with a certain preload. 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 according to the invention shown in FIG. 4 for ventilation differs from that according to FIGS. 1 to 3 in that there is no pin closing the opening 5 in the cap, but in that the membrane part 3 in addition to the web 9 running all around, the tear ring 7 and the membrane 4 with the central opening 5 has a diametrically arranged crosspiece 11, which is fastened on both sides to the circumferential crosspiece 9, for example welded on, glued on or locked in, and has a pin 12 attached to it in one piece.
  • the pin 12 bears against the opening 5 of the membrane 4 from below, so that if there is excess pressure in the container, the membrane lifts upward from the pin and in this way vents the container.
  • the cap 2 is removed in the usual way, as unscrewed, and the membrane part 3 is torn out using the tear ring 7.
