Definitions

  • the invention relates to a container with a lid according to the preamble of claim 1.
  • a container with a lid of the type mentioned at the outset is known, for example, from Sun Coast Plastics, Inc.
  • the two sealing lips are arranged concentrically in the lid surface and form a circumferential groove between them, which widens towards the open side of the lid.
  • the upper edge of the container engages in the groove, so that the sealing lips lie against the edges of the end face that surrounds the container opening.
  • This has decisive disadvantages.
  • no membrane closing the container opening can be attached to the end face of the container surrounding the container opening.
  • the inner sealing lip touches a container surface which is unsuitable as a sealing surface because it is geometrically asymmetrical or is scratched.
  • these edges of the end face rub against the sealing lips, so that they are exposed to considerable wear.
  • a screw cap is tightened so much that the sealing lips are permanently deformed or even destroyed, so that their sealing function is lost.
  • Containers with sealing washers are also generally provided with a sealing membrane which covers the container opening and which is connected to the end face surrounding the container opening. Such a sealing membrane must then be removed to open the container. As a rule, however, remnants of the binder and the closure membrane remain on the end face surrounding the container opening, which prevents the container from being tightly closed again with the lid. In addition, there is also the risk that the sealing washer may be damaged, for example, by screwing the screw cover too tightly.
  • the object of the invention is to design a container of the type mentioned in the introduction in such a way that the disadvantages mentioned are avoided.
  • the two sealing lips engaging on different surfaces of the container ensure that the container is absolutely sealed, since the sealing functions are distributed over two different surfaces. This even makes it possible to dispense with a sealing membrane.
  • a closure membrane can also be used, which can be placed on or connected to the end face surrounding the container opening. Any remnants of the binder remaining after the removal of the sealing membrane will still not cause the lid to leak, since the second circumferential sealing lip ensures adequate sealing.
  • the two sealing lips which also act on surfaces, provide increasing resistance to the closing process when the container is closed with the lid, thereby preventing damage to the sealing lips when the lid is attached.
  • sealing lips acting on two different surfaces, it is also possible to compensate for manufacturing-related tolerances of the container and the lid, so that there is always sufficient contact pressure of the sealing lips on the surfaces of the container to ensure that the lid is sealed tightly.
  • the interacting sealing lips regulate the contact pressure in the different surfaces of the container. Overuse of the sealing lips and thus cracks, signs of fatigue and the like are avoided.
  • the first and second sealing lips can have different configurations and angular positions.
  • the embodiment according to claim 2 has the effect of a pressure relief valve, so that an excessively high pressure in the container space enables the first sealing lip to be lifted off.
  • the design according to claim 3 ensures an increased sealing function and is particularly suitable for containers in which there is no danger that the permissible nominal pressure inside the container will be exceeded. Similar considerations also arise for the formation of the second sealing lip.
  • An embodiment of the second diaphragm lip according to claim 4 causes a particularly tight container closure.
  • the embodiment according to claim 5 also has a certain valve function. Moreover, when such a sealing lip is used on a diverging side surface when a lid is attached to the container, progressively increasing resistance can be generated.
  • An embodiment according to claim 6 offers the possibility of bending the edge region of the second sealing lip back against the container opening when the cover is attached, which on the one hand results in a strong contact of the sealing lip on the side surface and on the other hand a high sealing function.
  • the sealing lips can be formed directly on a cover or formed on an insert body. The latter makes it possible to manufacture the cover part and the insert body from different materials which are adapted to the individual functions.
  • the end face surrounding the container opening is expediently designed according to claim 8, which is particularly advantageous if a closure membrane is to be attached to the end face. But they are also training courses of the container according to claim 9 possible.
  • the container 2 has a container opening 10 which is surrounded by an end face 12.
  • the end face 12 forms an angle ⁇ of 90 ° with the container axis 14 of the container 2.
  • a side face 16 adjoins the end face 12 and extends from the end face at an angle ⁇ away from the container axis 14.
  • the cover 4 contains an insert 18 on which a first circumferential sealing lip 20 is formed, which is inclined at an angle a to the end face 12.
  • the first sealing lip 20 is inclined outwards from the container axis 14.
  • a second sealing lip 22 is integrally formed on the insert 18 and forms an angle ⁇ with the side surface 16. The second sealing lip is directed away from the container opening 10.
  • a closure membrane 24 is arranged, which can rest loosely on the end face 12 and is pressed by the first sealing lip 20 or connected to the end face 12, for example glued.
  • the closure membrane 24 has an outwardly projecting edge 26, on which the closure membrane can be grasped to open the container and can be torn off from the end face 12.
  • the first sealing lip 20 points outwards from the container axis 14 and the second sealing lip 22 is directed away from the container opening 10.
  • the sealing lips thus bring about a certain valve function, which enables pressure equalization from the inside of the container to the outside.
  • FIG. 2 shows a further container 28 with a cover 30 designed for screwing. Threaded parts 32 of the cover interact with threaded parts 34 of the container.
  • a first sealing lip 36 is arranged, which abuts an end face 38 which surrounds the container opening 40.
  • the first sealing lip 36 is inclined at an angle a to the end face 38 and inwards against the container axis 14.
  • the lid 30 contains a second sealing lip 42 which is inclined in the direction of the container opening 40 and abuts the side surface 44 which is inclined to the container axis 14.
  • the second sealing lip 42 forms an angle ⁇ with the side surface.
  • both sealing lips 36, 42 are inclined in the opposite direction of flow from the container, so that they are pressed more strongly against the end face 38 and the side face 44 due to an internal pressure in the container.
  • FIG. 3 shows a third variant of a container 46 with a lid 48, which in turn is equipped with a snap lock similar to that of the example in FIG. 1.
  • the container 46 has a bead 50 on which an inner bead 52 of the cover 48 engages.
  • the lid contains a first sealing lip 54, which is inclined at an angle a to the end face 56 which surrounds the container opening 58.
  • the cover 48 contains a second sealing lip 60 which bears at an angle ⁇ on a side surface 62 of the container.
  • the side surface 62 is arranged to diverge from the container axis 14 and forms an angle e with the vertical.
  • the second sealing lip 60 is practically approximately perpendicular to the side surface 62, so that when the cover 48 is attached to the container 46 it forms an edge 64 which is bent back against the container opening 48.
  • the first sealing lip 54 which is inclined away from the container axis 14, practically forms an overpressure valve with the end face 56. If the pressure in the container 46 is too high, gas can escape via the first sealing lip 54 into the annular chamber 66, which is formed in the cover 48 between the first sealing lip 54 and the second sealing lip 60. An increase in pressure in the annular chamber 66 causes the edge 64 of the second sealing lip 60 to be pressed more strongly against the side surface 62, as a result of which the sealing effect is improved.
  • the closure concept according to the invention only works in the presence of both sealing lips, which interact and that over the entire circumference of the container opening.
  • the two sealing lips ideally balance the forces that occur within the closure.
  • the specific design of the sealing lips allows close contact with the Container and a compensation of its tolerances.
  • the main element of the closure concept is the combination of a specific position and the angular position of the two sealing lips.
  • the position of the outer sealing lip is ideal for a good reclosure, especially if a membrane (safety closure, etc.) is also used.
  • the closure concept according to the invention is in principle also suitable for applications in which the internal container pressure is greater or less than the atmospheric pressure.
  • double sealing lips can also be used for a cover insert that can be injection molded independently of the cover and inserted into the cover using high-performance machines. Under certain circumstances, production can also be carried out using a modern combination injection molding process (injection of two different plastics in one operation).
  • This closure concept is of particular interest if the contents only allow specific plastics for migration reasons or if special characteristics (flexibility, etc.) are necessary.
  • the container opening can be of normal construction and does not impose any tighter tolerances than a normal screw cap.
  • Existing glass container designs can be easily adapted to the new closure concept at little cost.
  • Normal stripping demoulding can be used to manufacture the cover. Because the closure concept only generates low lateral forces (radial forces) when closed, thread profiles can also be used for stripping.
  • the locking concept tolerates a large range for the locking torque in a capping machine and still remains functional.
