Definitions

  • the invention relates to a Schlitzschliessventil for container openings or the like., According to the The preamble of claim 1.
  • the invention relates in particular to Self-closing and opening valves for installation in an opening in a container or for Completion of a cap.
  • the slit closure valve according to the invention is characterized by the features of Claim 1. Accordingly, the membrane part of the slot closing valve is designed to a wall region of the membrane part is connected at an acute angle to the base part is. In the region of the connection point are one or more slit-shaped passage openings intended. These passage openings serve the purpose of creating a pressure equalization, by allowing entry of ambient air into the interior of the container thereby, when in Container interior conditions prevail. In contrast, the slot-shaped Passages kept closed at an overpressure in the container interior, so that the overpressure only in a release of the slot-shaped outlet opening at a e.g. can express central region of the membrane part.
  • the slit closure valve according to the invention has a particularly simple, uncomplicated structure and can be including the said openings in one operation, e.g. by injection molding, produce economically.
  • a production further favoring and at the same time promoting the functions mentioned Design of the slot closing valve provides that the membrane part is a pointed roof-shaped Configuration can have.
  • Other developments of the invention are in the claims listed.
  • the slit closure valve according to the invention comprises a general reference numeral 1 supporting base part and a membrane part, which bears the general reference numeral 2.
  • Base part 1 has an annular configuration and serves to the slot closing valve in a to be closed opening of a container or cap or the like. To assemble.
  • the membrane part 2 is at a suitable intermediate location between the axial ends of the base part 1, preferably near an axial end, as indicated at 7, on the base part 1 integrally formed and preferably has a substantially pointed roof-shaped configuration, as can be seen in particular from Fig. 2.
  • the membrane part 2 accordingly comprises Side wall portions 3, 3 ', which at an angle ⁇ relative to an inner circumferential surface. 6 the base part 1, which may be concentric with the central longitudinal axis of the slot closing valve, are inclined inwards.
  • the membrane part 2 has a central ridge region 4, the preferably in a radial plane to the central longitudinal axis.
  • a slit-shaped Outlet opening 5 is introduced in the ridge region 4.
  • the slot-shaped outlet opening 5 has the slot-shaped outlet opening 5 a unidirectional extension along a Crosshead axis of the slot closing valve, but may, if desired, also another Alignment of the slot-shaped outlet opening 5 may be provided.
  • the slit-shaped outlet opening 5 be formed Centerless by being e.g. along can extend both transverse main axes of Schlitzschliessventiles.
  • Fig. 1 shows the slot-shaped outlet opening 5 in the closed position, which in the Rest position of the slot closing valve due to the inherent elastic property of Material from which the slit closing valve consists is taken.
  • Preferred materials are rubber-elastic materials, such as elastomer, silicone material, or natural or Synthetic rubber material and the like .
  • the elastomers are thermoplastic Elastomers preferred because of their good processibility by injection molding.
  • the side wall portions 3, 3 ' have a thickness which differs from the Ridge region 4 tapers in the direction of the connection point 7 and near the connection point 7 creates a tight lip-like structure.
  • each of the ridge region 4 is provided with a slot-shaped passage opening, as shown in FIG. 1 at 8, 8 'is indicated.
  • Each passage opening 8, 8 ' has a unidirectional in Circumferential direction of the membrane part 2 facing orientation and represents a slot in the Resting state of the slit closing valve by the inherent elastic properties of the compliant material of which the side wall portions 3, 3 'are made, in the closed Condition is maintained. It is understood that the number and arrangement of the slot-shaped Through openings 8, 8 'not on the above and shown in Fig. 1 Embodiment is limited. Rather, more or less than two could slit-shaped through holes 8 may be provided, and further, the angular Distance between adjacent slot-shaped through holes other than diametrically be.
  • the container contents can therefore via the slot-shaped outlet opening 5 to the outside delivered as long as the pressure acts as soon as the crushing force on the container is taken away and thus the container interior returns to a depressurized state, will the slot-shaped outlet opening 5 due to the elastic return behavior of the deform resilient material back into the closed position and the container interior hermetically sealed against the outside environment.
  • the introduction of the openings together with the formation of the Slotted closing valve takes place. This can be accomplished by using appropriate Areas of an injection mold according to the location of the openings 5, 8 when demolding cutting elements are advanced into the material to cut into it, which can be used simultaneously in further advancing the Eject process to accomplish.
  • the dimensioning of the slot closing valve and the Material choice is also preferably made so that the locking force for the Outlet opening 5 has sufficient strength that this under a slope pressure of the Container contents is not yet brought into the open position, but only when exposed an external force on the container, which puts the container contents under an overpressure, the greater than the pitch pressure is.
  • a container provided with the slit closure valve could Therefore, be everted without the container contents leaking.
  • Membrane part not pointed roof-shaped Another can be provided appropriate arched configuration, provided that allow the Connection of the membrane part on the base part such that at least close to the Through openings of said angle ⁇ less than 90 ° is maintained.
