PET Bottle for Efficient Recycling Comprising an Easily Removable Label and a Cap without a Retainer Ring

Abstract

The present invention relates to a PET bottle which increases recycling rate of PET bottles, wherein the PET bottle comprises a label that assembles the cap 20 without a retainer ring 21 on to the body 10 of the PET bottle, seals from the top of the cap 20 to the upper portion of the body 10 with the one continuous label and safety seal film 50, and has vertical parallel perforated lines 51 on one portion of the sealed label and safety seal film 50. A flap 52 extends from the end of the upper end of the perforated lines 51 to assist with tearing the label. The sealed label and safety seal film 50 covers the upper portion of the body 10 in shape of an inverted funnel, such that when it is torn along the perforated lines 51, the film 50 will be separated naturally from the bottle.

Claims

1. A PET bottle for efficient recycling of the PET bottle by allowing easy removal of cap and label, wherein the PET bottle comprises: a body 10 of PET bottle; a cap 20 closed on the top of the body 10 of the bottle, wherein the cap 20 does not have a retainer ring; and a label and safety seal film 50 covering from top of the cap 20 to the upper part of the body 10 of the bottle, wherein the film 50 has a flap 52 with vertical parallel perforated lines 51 for removing the film 50.

2. The PET bottle as claimed in claim 1, wherein the flap 52 extends in upwardly from the film 50.

3. The PET bottle as claimed in claim 2, wherein the vertical parallel perforated lines 51 are formed from top to bottom of the film 50, thereby the whole film 50 is removed from the body 10 of the bottle when the flap 52 is torn off.

4. The PET bottle as claimed in claim 3, wherein the upper part of the bottle includes a neck and the body 10 having a height of about 0.5 to about 5.0 cm.

5. The PET bottle as claimed in claim 1, wherein the film 50 is a shrink film, and functions as a safety seal for sealing the cap and as a label in which necessary information is printed.

Description

BRIEF DESCRIPTION OF DRAWINGS

[0032] FIG. 1 depicts perspective view of a conventional PET bottle for beverage, wherein (A) is a perspective view with an unopened cap 20, and (B) is a perspective view with the cap 20 opened.

[0033] FIG. 2 depicts perspective view of PET bottle in which the conventional cap 20 without a retainer ring is completely sealed with the safety seal film 40, wherein (A) is a perspective view with the safety seal film 40 on the bottle, and (B) is a perspective view with the safety seal film 40 removed and the cap 20 opened.

[0034] FIG. 3 depicts perspective view of PET bottle in which the entire cap 20, without a retainer ring, is sealed with the label and safety seal film 50, wherein (A) is a perspective view with the label and safety seal film 40 still on the bottle, and (B) is a perspective view with the label and safety seal film 40 removed and the cap 20 opened.

DETAILED DESCRIPTION

[0035] The present invention relates to various PET (polyester) bottles for holding varieties of liquid content such as drinking water, beverages and such, wherein the PET bottle can significantly increase the recycling rate by having a label that is easily removable as the cap of the PET bottle is opened.

[0036] FIG. 3 is perspective view of PET bottle in which the entire cap 20, without a retainer ring, is sealed with the label and safety seal film 50, wherein (A) is a perspective view with the label and safety seal film 50 still on the bottle, and (B) is a perspective view with the label and safety seal film 50 removed and the cap 20 opened.

[0037] The PET bottle which increases recycling rate of PET bottles according to present invention comprises a label that assembles the cap 20 without a retainer ring 21 on to the body 10 of the PET bottle, seals from the top of the cap 20 to the upper portion of the body 10 with the one continuous label and safety seal film 50, and has vertical parallel perforated lines 51 on one portion of the sealed label and safety seal film 50. A flap 52 extends from the end of the upper end of the perforated lines 51 to assist with tearing the label. The label can be easily torn by pulling the flap 52 in vertical direction along the perforated lines 51.

[0038] Since the sealed label and safety seal film 50 covers the upper portion of the body 10 in shape of an inverted funnel, as it is torn along the perforated lines 51, the film 50 will be separated naturally from the bottle. The length of the film 50 extending vertically from the inverted funnel is preferably, but not limited to, 0.5˜3.0 cm.

[0039] Because the cap 20 does not have a retainer ring, when the film 50 is removed by tearing it along the perforated lines 51, and the cap 20 is taken off, only the body 10 of the PET bottles remains. Therefore, without having to remove the retainer ring or the label separately, the body 10 of the PET bottle is naturally separated from other components.

[0040] As the cap 20 is made of polyethylene (PE) or polypropylene (PP), and the label and safety seal film 50 is made of polystyrene (PS), PET, or polypropylene (PP), these two components can be easily removed from the body 10 of the PET bottle. The inventor of present invention has developed a shrink film used for the label and was granted following patents: Korean Patent No. 10-926716, No. 10-1156607, and No. 10-1486799.

[0041] Preferably, these films are used as the label and safety seal film 50.

[0042] The label and safety seal film 50 not only acts as a safety seal by completely sealing the cap 20, but also acts as a label by having various kinds of information regarding the product (e.g. manufacturer, reseller, phone number etc.) printed on its upper inclined surface.

[0043] The PET bottle of present invention does not require a label to be adhered on its body, and uses a label with significantly less surface area compared to conventional PET bottles. Therefore, it reduces amount of shrink film used as the label and can contribute to cost reduction.

[0044] The present invention ensures safety of the product by sealing the cap, which does not have a retainer ring, with the label and safety seal film, and at the same time, provides a novel label for PET bottles which eliminates need for removing the label separately, and increases recycling rate of PET bottles.

[0045] The present invention may be put into practice with simple modifications and variations by persons skilled in the art, and such modifications and variation are all within the scope of the present invention.
