Definitions

  • the invention relates to a structural unit consisting of a dispensing valve for dispensing in a container under pressure liquids, foams, gels od. Like. Flowable materials, and a seal, according to the preamble of claim 1, and a container with such a unit.
  • Such a unit is known from US 3,845,888. The same applies to a container with such a unit.
  • the dispensing valve or its valve body is held by a so-called valve plate within a container lid opening, under latching to the peripheral edge of the lid opening.
  • the valve body is also connected by latching with the valve plate.
  • the valve disk has a latching cylinder extending through the cover opening into the container interior with a detent nose extending over the outer circumference, which for the purpose of latching the valve disk and thus the dispensing valve within the cover opening The peripheral edge of the same engages behind.
  • the known construction has the advantage that the valve disc can be made of inexpensive plastic; because it is no longer necessary to fix the usually made of tinplate valve plate by crimping with the interposition of a sealing element at the opening edge of the container or lid opening, such as e.g. in EP 0 471 503 A2 or also EP 0 697 348 A1 is proposed.
  • the latter version also corresponds to the state of the art practiced today. This prior art is expensive to produce and in particular also expensive in terms of the materials used.
  • the present invention has for its object, while maintaining the material and fixing technical advantages of the solution according to US 3,845,888 further develop this to the effect that a secure seal of the container interior is ensured against the environment.
  • An essential point of the present invention is therefore that a separate sealing ring made of soft elastic sealing material used and between the dispensing valve or a valve plate associated therewith on the one hand and the container or lid opening limiting wall on the other hand is clamped.
  • the separate sealing ring is thus in a broader sense between the outer support of the dispensing valve and the valve plate associated therewith on the container or container lid and the locking means cooperating with the container or lid opening, in particular the peripheral edge of the container or lid opening for the Locking the dispensing valve effective.
  • valve disk itself can be made of cheap plastic as in the prior art according to US 3,845,888. A crimp connection between the valve disk and the peripheral edge of the container or lid opening is not required.
  • the valve body of the dispensing valve can also be locked on the valve disk in a manner known per se, specifically with the interposition of a sealing disk made of soft elastic sealing material.
  • the dispensing valve including valve plate can be made of relatively cheap plastic material. Sheet metal processing is no longer required. Nevertheless, a high sealing effect is guaranteed.
  • the sealing ring is designed as an annular disc.
  • An alternative imple mentation form is characterized in that the sealing ring is designed as an annular L-shaped profile.
  • the sealing ring is preferably arranged within a corresponding recess in the valve body or valve disc so that it is flush with the associated outer surfaces of this component.
  • the container or lid opening may be formed on the container-inner end of a ring wall which tapers into the container interior in a funnel-like manner.
  • the container or lid opening may be delimited by a circumferential bead. Bead and inner opening edge limit the container opening container outside or container inside in the axial direction.

Between this annular wall and a cylindrical part of the valve disk which is latched into the container or lid opening, the aforementioned annular gap is formed.

  • the container opening is produced by punching or turning. This creates a peripheral edge that is not protected from corrosion. In order to avoid corrosion in this area, it is extremely advantageous if the punching or cutting surface, which defines the peripheral edge of the container or lid opening, is protected in the installed state by sealing material from the container contents.
