The invention relates to a protector for containers that include a rivet that protrudes in the upper portion of the container, comprising an upper lid and a lower ring that can be coupled to the side wall of the container, the upper lid and the lower ring being attached to each other. The lower ring includes a plurality of locking tabs, which protrude from an interior face of the lower ring in an upwards direction and along the entire perimeter of the lower ring, said locking tabs having an angle of inclination with respect to a vertical portion of the lower ring, said locking tabs being designed to hold the side wall of the container and abut under the rivet present in the container, the upper lid including at least a negative portion that protrudes from an interior face of a perimeter flange, which is attached to the locking tabs in a closed state of the upper lid with respect to the lower ring.

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.

A rubberized food-grade device temporarily attaches to a beverage receptacle, preventing insects from entering the beverage but allowing individuals to drink from the receptacle freely. Different devices are contemplated for attachment to bottles, cans, or drinking glasses and are shaped in novel ways.

A unitary, single-use, sanitary sterilizing wipe for a beverage can. It has a number of can wiping interfaces incorporated into its design that matingly conforms to a standard beverage can, and uses a natural sterilizing fluid that is frictionally wiped onto the can's outer surfaces before drinking from the can. It may be used anywhere by opening the polymer seal, removing the wipe, placing it on the top of a beverage can and twisting it under pressure to sterilize the can.

A protective lid for containers, having an upper lid provided for covering the upper part of the container, and a hinge section provided for exerting an angular movement of the upper lid in relation to the upper face of the container, the hinge section having at least one connecting portion with a contact surface provided for being adhered by an adhesive material to the lateral wall of the container. The contact surface has an arched trajectory with a radius that is substantially equal to the bend radius of the lateral wall of the container, and with a length that is less than the circumferential length of the lateral wall of the container. In this way, the protective lid is not provided with a lower ring for securing same to the container, thereby simplifying the production and assembly process.

A unitary, single-use, sanitary seal for a beverage can. It has a number of redundant sealing interfaces incorporated into its design and uses of both friction fit and captive seals. It may be installed at the canning facility or elsewhere by a third party, with or without the use of heating. Its dome construction flexes the side walls and seals outward in an expansive manner to allow installation. To remove, the seal must be destroyed, leaving a visual indication. It allows a conventional six-pack ring to be used as well as the vertical stacking of groupings of cans. Antibacterial agents such as silver, copper, zinc, tin, or the like may optionally be incorporated into the seal's material to enhance or maintain sterility.

A closure system can be attached to existing paint pails, cans, and other, similar metallic containers. It includes a crimped insert ring attaching to the container and a primary lid, preferably having tamper-evident features. A secondary lid is seated on and seals to the primary lid, with the secondary lid possibly being made partially or completely from plastics, thereby facilitating its ability to reseal the paint container by way of a plug seal. The insert, primary lid, and secondary lid may have one or more annular grooves or ridges to facilitate their attachment to one another.

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.

The invention relates to a hygienic protective membrane (2) for a drink can (12) provided with a lid (14) with a circular edge (16) and a ring suitable to form an orifice in a detachable zone of said lid, the membrane (2) comprising a first and a second film (6) superimposed and adhered to each other, said membrane (2) being configured to be disposed with the first film adhered to the lid (14), the second film (6) being separable from the first in order to give access to the orifice of the lid. The membrane has a central portion (8) generally circular suitable to cover the lid (14) and a lateral portion (10) forming a strip from the circular portion and adapted to cover the edge of said lid.

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.
