Abstract
Official abstract text for this publication.
A retaining device ( 1 ) has a non-laminar self-closing valve ( 2 ) retained therein. The valve comprises a flange ( 8 ), and the rigidity of the flange ( 8 ) is increased by the device ( 1 ). The retaining device is a single-piece article.
First claim
Opening claim text (preview).
The invention claimed is: 1. A retainer device for retaining a non-laminar, flange-presenting self-closing valve in a closure for a container in which the closure is adapted for direct connection with the container, the device being separate from the closure for the container and separate from the container, the device having a crimping flange movable from an uncrimped position to a crimped position for engaging the said valve flange and sandwiching said valve flange between said crimping flange and a surface on the device to retain the valve in the device, the crimping flange being separate from the closure for the container and separate from the container, so that the device is fitted into said closure for the container in a single configuration which permits dispensing. 2. A device according to claim 1 , in which the crimping flange comprises an upstanding wall. 3. A device according to claim 1 , in which the device comprises a circular upstanding wall and the crimping flange comprises a circumferentially upstanding wall. 4. A device according to claim 1 , in which the device comprises a bead for snap-fitting the device into a closure. 5. A device according to claim 1 , in which the device comprises a sloping surface for receiving the valve flange. 6. A device according to claim 1 , in which the device is formed as a retaining ring. 7. A device according to claim 1 , in which the device is formed as a single-piece article. 8. In combination with a container, a retainer device for retaining a non-laminar, flange-presenting self-closing valve in a closure for the container in which the closure is configured for direct connection with the container, the device being separate from the closure for the container and separate from the container, the device having a crimping flange movable from an uncrimped position to a crimped position for engaging the said valve flange and sandwiching said valve flange between said crimping flange and a surface on the device to retain the valve in the device, the crimping flange being separate from the closure for the container and separate from the container, so that the device is fitted into said closure for the container in a single configuration which permits dispensing. 9. A combination as claimed in claim 8 , in which the device is snap-fitted into the closure. 10. A combination as claimed in claim 8 , in which the device and the closure include co-operating sealing beads for fixing the device into the closure.
