PLASTIC COVER FOR CANS WITH OPENER FOR OPENING AND RE-CLOSURE

Abstract

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.

Claims

1. The A plastic cover for cans with opener for opening and re-closing comprises a cylindrical plastic cover which ends by rounded edges in the wall at which one end is designed the recess and at the cover is designed trapezoid opening with shorter side oriented toward its centre and in its extension integrally with the cover is designed movable trapezoid opener accordingly with the opening, so its shorter side length is approximately of of the cover diameter, and in the central part of the opener at its inner side is designed the ellipsoid recess, and the sides of this opener are spreading symmetrically at the angle of 45, and from the cover edge lowers down forming grip portion high as the one half of the wall, and on the cover is designed the ellipsoidal opening, so the recess and opening are compatible, and designed on the inner side of the cover are two ring barriers and two crescent barriers which ends are terminated by the barrier.

2. The plastic cover for cans with opener for opening and re-closing in accordance with claim 1 wherein the opening rim designed with the recess at the same height as the recess.

3. The plastic cover for cans with opener for opening and re-closing in accordance with claim 1 wherein the grip portion of the opener comprises designed ribs.

4. The plastic cover for cans with opener for opening and re-closing in accordance with claim 1 comprises low density polyethylene.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The plastic cover for cans with opener for opening and re-closing according to the invention and FIGS. 1, 2, 3, 4, 5, 6, and 7 contains basically of the plastic cover 2 of cylindrical shape which through rounded edges ends in the wall 3, dimensioned in way that by the soft press to the cover 2 makes firm and separable connection with can 1. At one section of the wall 3 of the cover 2 is designed rectangular recess 5. On the cover 2 is done a trapezoidal opening 2 which shorter side is oriented toward its centre while in its extension integrally with cover 2 the movable trapezoidal opener 4 is done in accordance with the opening 2 so its length of the shorter side 4 is equal to approximately of the cover 2 diameter. The opener 4 sides are spreading symmetrically toward the rim at an angle of 45, and from the edge of the cover lower down forming the grip portion 3 with height equal to the one half of the wall 3, so in closed position the opener 4 abuts into the recess 5 of the cover 2, sealing at the same time the opening 2 which disables leaking of drinks and enables at the same time to keep freshness and soda. At the grip portion 3 of the opener 4 the ribs 9 are designed enabling its easier opening and closing when consuming beverage. In the central part of the opener 4, at the inner side is designed the elliptical recess 6 while at the cover 2 is designed the opening rim 6 of the same elliptical shape and analogous position with the recess 6. At the opening rim 6 is designed the recess 10 which lies toward the inner side of the can 1 and is of the same height as the recess 6 on the opener 4. When closing the opener 4 the recess 6 goes into the opening 6 and in that position with recess 10 makes the function of cork. At the inner side of the cover 2 two concentric barriers 7, 7 are designed in the shape of ring recess with diameter smaller than the cover 2 diameter, preventing the liquid leaking into the dirtiest channel on the can. At the inner side of the cover 2 symmetrically in relation to the sides of the opener 4 are designed two crescent barriers 8, 8 which edges are terminated by the barrier 7. The both barriers prevent unnecessary leaking of the content over the surface of the can 1.

[0028] The plastic cover 2 is manufactured of low density polyethylene.

[0029] The functioning mode of the plastic cover 2 for the can 1 with opener 4 for opening and closing, according to the invention is simple and in obvious way follows from the former description of the invention and the Figures of the plan, so it is not necessary to explain it particularly. However, it is necessary to emphasize for the application of the cover 2 is needed to remove the metal cover of the can 1, and then on that opening put the plastic cover 2 and by gentle pressing make firm and separable connection with the can.

[0030] When consuming beverage using the grip portion 3 opens the opener 4 and after using closes it when the grip portion 3 pushes until abut into recess 5 in the wall 3 of the cover 2. The cover 2 is easy to remove from the can 1 and it is re-usable.

INDUSTRIAL AND OTHER APPLICATION OF THE INVENTION

[0031] The invention application arises from the above descriptions and plans in obvious way, so it is not necessary to describe it particularly. Sufficient knowledge of the subject field of the average expert is needed for successful application of the present invention and on the basis of given description. All instructions and functional characteristics of the invention the inventor has successfully checked on developed prototype.

[0032] As well, any structural of functional improvements are considered to be covered by this application.
