Abstract
A self sealing slit valve for closing off a container opening comprises a diaphragm part having a slit-shaped pour opening. The diaphragm part is made of a first thermoplastic elastomer material having resilient property, which is integrally formed to a base part made of a second thermoplastic material different from the first thermoplastic elastomer material. The slit valve according to the present invention is a molded part which is formed in a single operation by a two-component injection molding process.
Claims10
A slit valve for closing off a container opening comprising a diaphragm part having a slit-shaped pour opening and made of a first thermoplastic elastomer material having resilient property, said diaphragm part being integrally molded onto a base part of a second thermoplastic material different from said first thermoplastic elastomer material so as to be formed as one piece therewith.
A slit valve arrangement for closing off a container opening comprising
- a slit valve having a diaphragm part having a slit-shaped pour opening, said diaphragm part being made of a first thermoplastic elastomer material having resilient property, and being integrally molded onto a base part made of a second thermoplastic material different from said first thermoplastic elastomer material, and
- a securing element adapted to be mounted to a container portion for fastening the base part of the slit valve to the container portion, said securing element comprising a cover part integrally hinged thereto and swivable between a release position and a closing position relative to said diaphragm part, and a sealing ring molded to said cover part for engaging an opening in the base part of the slit valve, which is oriented with respect to said sealing ring in the closing position of the cover part, a portion of said diaphragm part containing said slit shaped pour opening is exposed at said opening of the base part.
