Embodiment Construction

[0033] Such as image 3 As shown, the present invention includes a plastic top layer (1), a PET layer (2), an aluminum foil (3), a heat-sealing layer (4) and an adhesive layer made of one of PE, PP, PET, and nylon with an annular handle. The combination of mixture layers (5, 6, 7) to hold all the layers together to form a composite material. The composite material will be completely cut along a circle to form a seal, and the top layer (1) will be partially cut to form a handle (10). The PET layer is used as a buffer layer to ensure that the aluminum foil (3) is 100% intact and protect the contents in the container.

[0034] Such as Figure 4 As shown, after the induction heat sealing process, the seal will adhere to the mouth of the container (8) to protect the contents of the container, as described above. After removing the cover (9), we can see the seal with its outer peripheral ring-shaped handle (10). The ring handle (10) does not stick to the lower layer (2), so that it ca...

Abstract

Our invention is a seal for a container. It is an induction heat seal with a ring-shaped handle 10 to allow easy removal of the seal from the container, the seal comprising a transparent and rigid plastic layer, a PET layer, an aluminum foil layer as well as a heat sealable layer below the foil. The ring-shaped handle 10 allows the seal to be lifted with only one finger and hence can be removed easily. For dry lamination, the gravure roller is specially designed to apply glue to only the designated area to enable more efficient transfer of force to remove the seal. For die cutting, the die cutting mould is designed to apply full cut on the outer perimeter of the seal and partially cut on the inner circle to produce the ring-shaped handle.

Description

Technical field [0001] The invention relates to a seal for a container, in particular an induction heat seal with an annular handle to facilitate the removal of the seal from the container. Background technique [0002] Various types of seals or closures currently exist, which are designed to seal on the opening of the container. To open the container after sealing, the seal must be broken or peeled off. Such seals or closures are used in various containers, for example, bottles for food, beverages, medicines, and chemicals. Their main function is to provide a protective element for the product in the container by separating the product from the external environment. In some cases, the seal can also indicate whether the contents have been reconciled. For food, seals are often used to seal the contents to prevent contamination of the food and maintain the freshness of the food. On the other hand, for chemical products, seals are used to prevent product leakage and spillage. I...
