Description

DESCRIPTION

Hygienic protective capsule and seal for beverage cans

Technical sector

The present invention is limited to the industry dedicated to filling beverage cans.

Background of the invention

There is no easy, cheap device that does not generate waste separate from the can, whose purpose is the hygienic protection of the liquid contained in a soda can.

It is a heat shrink tube and a disc. The disk sits on top of the can, and the tube covers this disk and part of the side of the can.

The set is simple and practical, the can being closed and protected in its upper part by the disk and in its entire upper side by the heat shrink tube.

It is placed at the factory and protects from dirt, during all transport and storage, all parts of the can that may be in contact with the liquid when serving or with the liquid and the consumer's lips when drinking directly from the can.

Explanation of the invention

The present invention refers to the use of a thin disk, which is placed on the upper part of the can and a heat shrink tube, which once shrinked, hugs and holds this disk in addition to covering the upper part of the side of the can.

The upper disc can be made of any material, cardboard, plastic, sheet metal, etc.

The diameter of the disc is slightly larger than that of the top of the can, so that when the heat shrink tube contracts, it automatically centers this disc with the top of the can.

The disc can be painted, engraved, with offers, advertising, etc., on one or both sides, it can even carry braille text.

The heat shrink tubing is larger in diameter than the can, so it can be easily inserted or inserted. The heat shrink tube is placed protruding approximately 1 centimeter above the disk so that when contracted, its upper part bends over the disk creating a perfectly adjusted closure.

The remainder of the heat shrink tube is attached to the side of the can according to the arrows indicated in Figure 2.

The heat-shrinkable tube and disk assembly, once in place, offers hygienic protection of all surfaces of the can that may be in contact with the liquid contained when pouring it, or with the liquid or the consumer's lips if it is drunk directly from the can.

The heat shrink tube fits perfectly to the disc and to the side of the can as it is heat shrink material.

It is advisable to use a recyclable material for both the disc and the heat shrinkable material, although any of the existing materials on the market can also be used, including polyethylene, PTFE, PVDF, PVC, NEOPRENE, etc ...

It is estimated to place a tape of length greater than 8 centimeters with adhesive only at its two ends, placed at an angle, with one end glued to the heat shrink tube and the other glued to the can, so that when the shrink tube is slightly rotated with respect to from the can, in the sense of opening a tap, the tape remains slack, allowing to lift the hygienic protection assembly for beverage cans and open the can, avoiding with this tape separate parts of the can assembly.

Brief description of the drawings

Figure 1. You can see the heat shrink sleeve (1) located above the disk (2) and the soda can (3). It can be seen that the diameter of the heat shrink sleeve (1) is greater than the diameter of the disk and the can to facilitate their placement.

Figure 2. You can see the heat shrink sleeve (1) and the disk (2) already placed in the can (3), before its heat shrinkage. The arrows indicate the direction of contraction of the sleeve (1) when shrinking.

Figure 3. Can (3) with its protective capsule (1) already shrunk. The disk (2) is embraced and held by its upper part and to the point (4) by the already thermo-shrinkable tube. The rest of the shrink tubing has been adjusted to the side of the can from points (5) to (6).

Figure 4. The tape (7) can be seen, which is glued only at its ends, and placed with one end glued to the top or hygienic protection (1) and the other end glued to the container or can (3).

Figure 5. The tape (7) is attached to two different elements, the set or hygienic protector and the can, so that when rotating one with respect to the other in the direction (8), the tape becomes loose and separates in its central part that is not glued, of the set or hygienic protector and of the can, but both remaining united by the tape to avoid their separation and loss.

Figure 6. The hygienic protective assembly (1), including the disc, totally separated from the can (3), but attached to it by its captive tape (7).

Description of a preferred embodiment

It is an individual protective cover to keep the contiguous opening area of beverage and soft drink cans clean and hygienic, which being a protection device against dirt, is characterized by being individual for each can and consists of a disc and a thermo tube retractable.

The heat shrink tube for the hygienic protection of beverage cans will be placed individually in each can unit, thanks to its larger diameter than the diameter of the can.

Subsequently, it is heated or passed through a heat tunnel to cause the tube or seal to heat shrink, leaving the upper disk immobilized and centered.

The set covers the entire top and part of the side of the can.

It fits perfectly to the sides of the can and its upper disk as it is made of retractable material.

Optionally, it can have a strip of paper or rubberized tape only at its ends (7), placed with one end glued to the top or hygienic protection and the other end glued to the container or can. It is positioned at an angle so that when the upper part is rotated the tape is slack and the hygienic protector assembly can be separated from the can.

Turning (8) in a counterclockwise direction of the upper part leaves the tape (7) free of tension, allowing the hygienic protector to be separated from the can, but remaining together to prevent one part from separating and thus avoiding its loss.

Claims (1)

1. Set for the hygienic protection of beverage cans, composed of an upper disk (2) of any material and a diameter slightly greater than that of the upper lid of the can, and a tube or heat shrink seal (1) of somewhat diameter higher than the body of the can before shrinking.
