    Abstract: A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engagable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.

    Abstract: A heating and sealing head (1) for packaging machines (M1; M2; M3) of products in trays (V), comprising a fixed support group (2) provided with first actuation means (3) electrically connected to a pneumatic system (4) for delivering compressed air, and a mobile application group (5) mechanically coupled to the fixed support group (2) by means of first fixing means and comprising heating means (6) electrically connected to an electric current generator (7), preferably alternating, which activates the heating means (6) to produce heat useful for sealing a closing and packaging film to one or more trays for containing products when the trays themselves are arranged under the heating and sealing head (1) in a packaging machine (M1; M2; M3). In particular, the heating means (6) comprise an electromagnetic inductor body (8) which produces the heat due to the effect of the parasitic electric currents induced by a magnetic field generated by the electromagnetic inductor body (8) when crossed or affected by the electric current.

    Abstract: Long-term packaging using a combination of an induction seal and a reseal without release layers, both of which are activated by the induction heating process. The exemplary induction seal comprises a laminate of a heat-sealing layer, an aluminum foil layer, and a foam backing. The exemplary reseal comprises a low-density polyethylene foam core sandwiched between first and second layers of solid low-density polyethylene film. The reseal deforms during the induction heating process to be shaped to engage the outer and inner peripheral surfaces of the finish, so that the reseal is hermetic even after the induction seal is removed. Preferred containers are PETE with PP compression closures. Replaceable desiccant and oxygen scavengers may be used with food or other contained material. Precise timing of induction heating is required to achieve the desired result.

    Abstract translation: 使用感应密封和再密封的组合的长期包装，没有释放层，两者都通过感应加热过程激活。 示例性的感应密封件包括热封层，铝箔层和泡沫衬垫的叠层。 示例性的密封包括夹在第一和第二层固体低密度聚乙烯膜之间的低密度聚乙烯泡沫芯。 在感应加热过程中，再密封变形，以成形为接合精加工的外周表面和内周表面，使得即使在移除感应密封件之后，再密封也是气密的。 首选容器是具有PP压缩封闭件的PETE。 可更换的干燥剂和除氧剂可以与食物或其他含有的物质一起使用。 需要精确的感应加热定时来达到预期的效果。
