A cover for sealing a container having an interior chamber that holds a quantity of material therein. A first channel provided on a base of the cover receives a rim on the container's side wall. A first sealing member is provided on the base. A second sealing member provided on the lid is complementary to the first sealing member and is engageable therewith when the lid is moved to a closed position. A flexible bridge extends between the base and the lid. One of the first or second sealing members is a protrusion and the other is a second channel. The protrusion may be received within the second channel when the lid is closed. Pressure may be progressively applied to the lid to zipper the cover into a sealed position. When the lid is in the sealed position material cannot be accidentally or purposefully removed from the interior chamber.

A plastic cover for cans with opener for opening and re-closing manufactured of low density polyethylene consists of a cylindrical cover designed with trapezoid opening with movable opener of analogues shape which sides are spreading symmetrically toward the rim and from the edge of the cover lowers down forming the grip portion. On the opener firmly and un-separable connected to the cover on the inner side is designed the ellipsoid recess analogous to the opening of the cover. The opener abuts to the recess on the wall of the cover while the recess seals the opening and when it is closed it disables the leaking and keeping freshness and soda. On the inner side of the cover are designed concentric barriers preventing the leaking of the drink into the dirtiest channel on the can and crescent barriers preventing spreading of the liquid over the can surface.

The present invention relates to a resealable membrane lid for a container comprising a peelable portion and a removable portion. When the resealable peelable portion is peeled back, the seal onto the container is not disturbed. When the removable portion is removed from the container, the container contents may be accessed. The peelable portion may be resealed onto the container at any point in the process.

A security cover system and apparatus for beverage cans and other containers. The system includes a security cap that is installed upon the top of an unopened container for containing an adult beverage or the like. The cap is adapted for secure installation upon the top of a container having a top with a circumferential rim, such as an aluminum beverage can. The cap has catches engagable with the rim of the container. The system includes an opener tool with a specially shaped key portion thereon. The opener engages with a complementary slot in the cap to permit an authorized person, using the opener tool, to remove the cap from the container.

A pull-tab sealing member for a container containing an upper laminate forming a pull-tab bonded to a lower laminate capable of being heat sealed to a container's mouth or opening. The upper laminate defines the pull tab wholly within a perimeter or circumference of the seal. The sealing member further includes a sub tab layer or member under the gripping tab for concentric structural support.

A reusable closure system is disclosed for packaging applications. The closure system generally includes a base and hinged lid. The base is bondable to a package and includes a field of touch fasteners having one or more cut-lines therein defining a hinged pull-tab assembly. The lid includes a complementary touch fastener field and can be placed in the open position to expose the pull-tab assembly, which can then be peeled back to open the package by virtue of the bond between the pull-tab assembly and a frangible region in the package. After opening, the pull-tab assembly can be stowed to the lid, so as to provide a lid-based plug corresponding to the package hole. Optional tamper-evident elements allow a consumer to see the package has not yet been opened. Stay-open lid and anti-peel mechanisms may also be provided. A dispensable roll/fanfold of the closures can feed a flow-wrap packaging process.

A method for manufacturing a sanitary cover for a beverage can and relates to a technique for forming a cutting line along a circumferential surface of a sanitary cover while the sanitary cover is covering a beverage can, thereby maximizing the production efficiency of the sanitary cover having improved functionality. Also, the technique which, in three-dimensionally forming a cutting line as such, can carry out the process of forming the cutting line easily and rapidly via a simple structure, thereby increasing the production efficiency even further.

The present utility model relates to a new structural arrangement for various packages and to various package opening systems which can be used with any compatible package, and pertains to the technical field of packages in general, providing very advantageous, practical, reliable and functional results, with the greater objective of allowing packages to be recycled, preserving the environment and nature, which is a general practice worldwide by large companies which look after their image. The package comprises a body (10) shaped as a bottle, provided with an inner flexible tube (11) with a bent upper end, forming an inverted U, the upper portion (12) of which is kept in the vertical position outside the bottleneck, a stopper (14) being also provided at the liquid outlet (13); the body (10) and the tube (11) are closed by a lid (15) provided with a vertical projection (16) that forms an inner channel for housing the upper portion (12). Other arrangements are provided in structural variants.
