A method for manufacturing a container seal having an integral pull tab comprises providing a surface layer, an elastic layer, a top layer, an aluminum foil intermediate layer, and laminating a sealing adhesive layer of an adhesive thermoplastic resin or viscous agent to the intermediate layer. An adhesive surface and a non-adhesive portion are added to the thermoplastic resin layer, and placed on the aluminum foil to form a container seal laminate. The container seal laminate is cut to conform with an opening of the container to be sealed. The seal has an integral pull tab.

The inventive disclosures described herein pertain to an improved tamper-resistant/tamper-evident (TE) seal for containers of consumer/commercial product-containment vessels (such as, for example, prescription bottles, condiment bottles, etc.) that enables a user, and in particular older persons, to better grip and/or exert leverage to more-easily and reliably open such containers. In one embodiment of the improved TE seal, a typical prior-art seal configuration that features an inner seal with a small overlapping flexible pull-tab layer is improved by affixing the pull-tab to another substantially rigid upper layer such that a user can insert the pull-tab member between two of the user's fingers wherein the two user fingers are also disposed between the inner seal and the substantially rigid upper layer such that a user can more easily exert leverage/force to open the container that employs the tamper-resistant seal. This configuration is generally referred to as a “T-tab” configuration.

Specifically, it features an improved seal-removal assembly that provides a collapsible finger-receiving aperture that allows a user to insert at least one user finger (or an elongated tool, such as a writing utensil), and exert upward force to breach the container seal.

A tamperproof beverage container unsealed by rotation of a lid is disclosed herein. In a general example embodiment, the beverage container includes a body configured to seal a beverage therein, the body including at least a top surface, the top surface including a main surface and at least one sealing surface covering at least one body aperture, and a lid configured to at least partially cover the top surface of the body, the lid including at least one projection which unseals the at least one sealing surface to reveal the at least one body aperture when the lid is rotated with respect to the body.

A multi-layer film and a film package made from the film are described herein that provide resealing capabilities by utilizing a tacky layer within the multi-layer film. The multi-layer film can include an outer film portion including the embedded tacky layer and an inner film portion. An opening feature formed in the multi-layer film includes a flap configured to be manipulated by a user to create an opening through the multi-layer film. The inner film portion can include a release layer configured specifically to interact with the tacky layer to provide a desired separation peel force and resealing functionalities. The outer film portion can include an outer film layer disposed on an opposite side of the tacky layer from the release layer that is configured to permanently adhere to the tacky layer.

A package that includes a container and a container closure having a vacuum-indicating pull tab. The container includes a longitudinal axis extending therethrough, a mouth, and a sealing surface. The container closure includes a seal membrane sealingly and removably coupled to the container sealing surface to seal the container, and a pull tab configured to extend from the seal membrane. Manipulation of the pull tab provides an indication of the presence or absence of a vacuum in the package.

A tamperproof beverage container unsealed by rotation of a lid is disclosed herein. In a general example embodiment, the beverage container includes a body configured to seal a beverage therein, the body including at least a top surface, the top surface including a main surface and at least one sealing surface covering at least one body aperture, and a lid configured to at least partially cover the top surface of the body, the lid including at least one projection which unseals the at least one sealing surface to reveal the at least one body aperture when the lid is rotated with respect to the body.

The present disclosure relates to a transport closure (1) for use in a packaging container (10) for bulk solids. The transport closure includes a laminate of a first layer (2) and a second layer (3). The first layer (2) is delimited by a first layer peripheral edge (4) and the second layer (3) is delimited by a second layer peripheral edge (5). The second layer (3) comprises or consists of a weldable material and the first layer (2) has higher tear strength than the second layer (2). The first layer (3) is provided with a weakening line (6) defining a pull-tab (7) in the first layer (3) and having a first and a second base point (6a,6b). The base points (6a,6b) are arranged at a base end (7b) of the pull-tab (7), opposite to a gripping end (7a) of the pull-tab (7).
