초록 ▼

A method and apparatus are disclosed for preforming a heat-shrinkable member to a pre-selected configuration which may at least partially conform to a container to which the member is to be applied. The preformed member is subsequently applied to the container so that the member is retained in association therewith, such as for tamper-indication. The heat-shrinkable member is initially preformed by the use of a preforming mandrel which may be at least partially configured like the configuration of the container. After the member has been heat-shrunk on the preforming mandrel, it is positioned in association with the container, and thereafter heated so as to further conform the heat-shrinkable member to the configuration of the container. By this technique, hightly desirable control of the heat-shrinking process is achieved, thus assuring proper conformance of the heat-shrinkable member to its associated container. A further feature of the invention relates to final application of the preformed heat-shrinkable member by localized heating of the member, which desirably minimizes heating of the associated container and its contents.

A method of applying a generally cylindrical, heat-shrinkable member to a container, wherein said container includes a lower portion having a downwardly inwardly tapered configuration and a lid portion fitted to said lower container portion, said method comprising the steps of: providing preforming mandrel means at least partially configured like said container, wherein said mandrel means includes an inwardly tapered portion configured like said lower container portion; providing said heat-shrinkable member in the form of a spirally-wound cylinder which is predominantly heat-shrinkable in a radial direction, wherein said cylinder comprises a strip of heat shrinkable material wound spirally at an angle to the axis of said cylinder; positioning said heat-shrinkable member in association with said preforming mandrel means; heating said heat-shrinkable member so that it conforms to said preforming mandrel means to form a preformed member from said heat-shrinkable member, and releasably retaining an edge portion of said heat-shrinkable member positioned furthest from said preforming mandrel means during said heating, said preformed member being at least partially configured like said container and, including an inwardly tapered portion; moving said preformed member from association with said preforming mandrel means and positioning said preformed member in association with said container so that said tapered portion of said preformed member fits about the inwardly tapered lower portion of said container; and applying said preformed member to said container by heating said preformed member so that is shrinks and further conforms to the configuration of said container to overlie said lid portion. An apparatus for applying a heat-shrinkable member to a container wherein said container includes a lower portion having a downwardly inwardly tapered configuration and a lid portion fitted to said lower container portion, comprising: means for preforming said heat-shrinkable member to form a preformed member having a pre-selected configuration comprising preforming mandrel means positionable in association with said heat-shrinkable member, said preforming mandrel means being at least partially configured like said container and including an inwardly tapered portion configured like said lower container portion, and means for heating said heat-shrinkable member while in association with said mandrel means; means for releasably retaining an edge portion of said heat-shrinkable member positioned furthest from said mandrel means during heating thereof when the heat-shrinkable member is positioned in association with said preforming mandrel means to avoid premature shrinkage of said releasably retained portiqn of said heat-shrinkable member, to thereby form said preformed member with an inwardly tapered portion; means for positioning said preformed member in association with said container so that said inwardly tapered portion of said preformed member fits about said inwardly tapered lower container portion; and means for applying said preformed member to said container comprising means for heating at least a portion of said member to further conform said member to the configuration of said container so that said member overlies said container lid portion.
