摘要:
The invention relates to a pressure relief valve (2) for a packaging container (1), comprising a base plate (3), which can be fastened on a wall of the packaging container and has a valve opening (9), also comprising a membrane (4), which is arranged on the base plate (3) over the valve opening (9), wherein the membrane (4) has an adhesive on one side, and further comprising an intermediate layer (6), which is adhesively bonded to the adhesive-containing side of the membrane such that the membrane (4) has two remaining, parallel adhesive-containing peripheral zones for fastening on the base plate (3), wherein the membrane (4) is arranged on the base plate by way of the intermediate layer (6) such that a channel zone (14) is formed on the base plate (3), this channel zone covering over the valve opening (9) and resting right up against the base plate in the closed position.
摘要:
A container for dispensing a two-component liquid comprises an outer resilient container (2) for containing one component with a neck (4) defining an opening and an inner tubular container (16). The inner container (16) contains a piston (20, 22) slidably received within it. A closure member (18) extends over the entire area of the inner container and closes its lower end (16). The piston and the inner container define a reservoir for containing a second component. The neck (4) carries a closure cap (10,12) which affords a liquid dispensing opening (38). A first non-return valve (24, 32) communicates with the liquid dispensing opening (38) and with the interior of the inner container (16). An airflow path extends through the closure cap (10, 12) and the piston (20, 22) and includes a second non-return valve. The first non- return valve is arranged to permit liquid to flow from the inner container to the liquid dispensing opening and the second non-return valve is arranged to permit air to flow through the airflow path into the inner container. The closure cap (10, 12) cooperates with the piston (20, 22) so that movement of the closure cap in the downward direction results in movement of the piston towards the closure member. A finger (13) connected to the piston contacts the closure member (18) and moves it and thus opens the inner container, thereby permitting the component within it to fall down into the component within the outer container.

Das Einwegventil zur Abgabe einer Flüssigkeit aus einem Behälter (1), mit einer Außenkappe (3), die an dem Behälterhals befestigt ist und einen Austrittskanal (7) für die Flüssigkeit aufweist, ist dadurch gekennzeichnet, dass ein Ventilkörper (6) aus elastischem Material zwischen dem Behälter und der Außenkappe (3) angeordnet ist, dass der Ventilkörper (6) sich über die Öffnung des Behälterhalses erstreckt und einen Vorsprung (12) aufweist, der in den Austrittskanal (7) der Außenkappe (3) hineinragt und darin hin und her beweglich angeordnet ist, dass zwischen der Innenwand des Austrittskanals und dem Außenumfang des Vorsprungs ein Zwischenraum verbleibt, und dass wenigstens ein Schnitt (17) die Wand des Ventilkörpers (6) durchtrennt, durch den bei Ausübung eines Drucks auf den Behälter Flüssigkeit in den Zwischenraum des Austrittskanals (7) gelangt.
摘要:
A method for the production of a valve is provided comprising molding a valve body with a first mold, preloading the valve body with a second mold, molding a sealing portion in an open position onto the valve body, and releasing the preloaded valve body. The sealing portion enters a closed position when the preloaded valve body is released. When the valve is in use, the sealing portion opens when under a fluid pressure, and closes when the pressure is released.

Provided is a small, simple-structured, homogeneous and mass-producible excessive pressure release valve which works even at a relatively low excessive pressure to surely and safely release the pressure to the external world. The excessive pressure release valve 1 has an elastic rubber plate 10 and a reversibly openable slit 11 that passes through the upper and the lower surfaces and release the pressure to the external world when the internal excessive pressure stressing on the lower side surface, pushes and opens the slit 11 toward upper surface side 12. The elastic rubber plate 10 is made of silicone rubber containing 1-20% by mass of silicone oil.
摘要:
An ink container mountable on an ink jet recording apparatus comprising: an ink supply port formed on a first wall of the ink container and being adapted to supply ink in the ink container to the ink jet recording apparatus; and a differential pressure valve including a movable membrane, characterized in that the movable membrane is arranged in a plane perpendicular to the first wall.
摘要:
There is disclosed a fluid supply valve comprising a disc-shaped valve body which is equipped with a fluid supply port in the central portion thereof and composed of elastic material the fluid supply port being closed when the valve body abuts against a fixed valve seat placed so as to be opposite to the fluid supply port, and being opened when the valve body is separated from the fixed valve sea t, wherein the disc shaped valve body is equipped Further with a thin walled portion in the intermediate annular portion between the fluid supply port and the peripheral portion in the radial direction, and/or with an inflectional portion in the radial direction between the fluid supply port and the peripheral portion. According to the above constitution, it is made possible to minimize the reaction force at the time of the deformation of the valve body and thus to provide an ink tank valve capable of favorably supplying a recording head with a proper amount of ink.
