To manufacture a metal can having a tear-open lid and having a storage space for an object above the tear-open lid, the following procedure is used: first, a top edge of the can which has a smaller diameter than the inside diameter of the can body is formed, wherein a transition region (6) is formed. After the tear-open lid has been attached, this transition region is deep drawn so that the tear-open lid (2) is displaced towards the bottom (5) of the can. This produces the storage space. This procedure allows previously formed tear-open lids to be used, which safely guarantees the imperviousness of the seal of the tear-open lid.

A composite container is provided for holding products (e.g., stacked chips). The container includes a tubular body and a peelable membrane. The tubular body is made of at least one paperboard body ply having an inner surface and a metallized Oriented Polypropylene (mOPP) liner ply adhered to the inner surface of the paperboard body ply. A liner sealant is disposed on the inner surface of the mOPP liner ply, and the paperboard body ply and the mOPP liner ply are rolled outwardly to form a rim. The membrane, which has a membrane sealant on its inner surface, is sealed to the liner sealant in the area of the rim to close the container. When the membrane is peeled away, the membrane sealant and the liner sealant remain sealed to each other and cause separation within the mOPP liner ply, avoiding tearing and exposure of the paperboard in the rim.

A liquid container includes: an accommodating portion that accommodates a liquid and has an opening portion at an upper end thereof, a sealing film that seals the opening portion and that is capable of being perforated by being pierced by a perforating tool; and at least one linear pressure indentation that is linear and that is formed on a surface of the sealing film, wherein, a length of at least one pressure indentation is a length equal to or greater than 50% of a length from an end portion to an end portion of the opening portion in a direction in which the pressure indentation extends.

A tear-off lid with a curled edge of the removal opening is formed such that before the edge is curled, a plastics layer provided as a band of low thickness and preferably only 0.1 mm thickness is applied to the collar of the lid ring. In this way, a good seal of the cut edge of the tear-off lid is produced by economical means and with the possibility for production at a high rate.

Safety cover mechanism for a container that comprises: a sealer; tracks positionable over the upper surface of the container; and a shutter member slidable over the tracks such as to allow covering and revealing the opening by sliding the shutter member over the tracks. The safety cover mechanism is configured such that sliding of the shutter member over the tracks away from the location of the opening of the container causes at least a portion of the sealer to unseal the opening thereby indicating that the container has been opened. A safety mechanism for containers with a pull or a stay-on tab and a press button sealer, where the tab pivotally connects to the container upper surface via a connecting element, wherein the safety mechanism is configured to prevent rotation of the tab over the axis of the connecting element for preventing unauthorized penetration to the container.

The present subject matter provides a layered article for sealing an opening in a package for a high alcohol content product. The layered article has a facestock, a reclosure adhesive, a machine direction oriented film, and a sealing adhesive. The sealing adhesive provides a good long-term seal for the package that is resistant to degradation from alcohol. The machine direction oriented film provides an alcohol barrier between the product and the reclosure adhesive. Upon opening, the film tears clean and straight in the machine direction to allow a portion of the film to stay in contact with the package and another portion of the film to be pulled from the package to expose the opening. The reclosure adhesive provides resealing capabilities for the layered article after the initial opening of the package. The clean straight tear also provides a tamper evident feature for the package.

In an embodiment, the invention comprises a container comprising: a base; at least one sidewall extending upwardly from the base and terminating in a top edge, wherein the at least one sidewall is paper-based; a removable flexible membrane adhered to the top edge, wherein the membrane comprises a one-way valve; a liner ply at least partially adhered to an interior surface of the sidewall, wherein the liner ply is configured to at least partially release from the sidewall upon a pressure differential between the pressure within the container and the external pressure.

The invention relates to a lid (1) for a can for foodstuff, paint and so on, which lid comprises: ringlike bare part (2) defining a opening (3); a sealing foil (4) arranged an the base part and covering the opening; a lip (5) arranged with one end to the foil for tearing the foil; retaining means for retaining a free end of the lip adjacent the sealing foil, whereby the retaining means comprise a first retaining part being part (7) of the sealing foil and a second retaining part being (8) part or the lip.
