Improved closure and method for producing thermoplastic containers. |
摘要 |
<p>An improved integral thermoplastic closure for a container formed of a film or sheet, and method of manufacture. The closure includes a pair of interlocking fastener elements with ribs on either side of at least one of the fastener elements to provide a stiffening effect to assist a user in interlocking the fastener elements. By controlling the thickness of a base portion of the fastener element so that it has a thickness greater than the film, the spacing of the ribs adjacent to a profile can be controlled to provide the desired stiffening and wide-track feel in the fastener element.</p> |
