• the present invention relates to a foldable polyethylene terephthalate (hereinafter, referred to as "PET") bottle, and more particularly, the present invention relates to a foldable PET bottle which is formed with a plurality of folding lines, in such a way as to be capable of being folded, whereby the PET bottle can be carried, discarded and collected in a state wherein its volume is minimized.
• PET polyethylene terephthalate
• a PET bottle which is particularly useful for bottling water, beverage or foodstuffs, is manufactured by a blow molding technique.
• melted PET is poured into molds, and then, hot air is blown into the molds to form a PET bottle.
• a PET bottle is formed to have a variety of shapes, to be used as not only a water or beverage container but also a foodstuff receptacle.
• the conventional PET bottle has a drawback in that it unnecessarily occupies too much a space in a collecting bag when it is collected for a recycling purpose.
• an object of the present invention is to provide a foldable PET bottle which is configured in such a way as to be capable of being folded after use and thereby to decrease a volume of the PET bottle to the minimum, whereby distribution costs can be reduced, and a PET bottle collecting work can be implemented in a convenient manner.
• Another object of the present invention is to provide a foldable PET bottle which is formed in such a way as to be capable of being discarded in a folded status after use, whereby a bulk of a garbage bag can be remarkably decreased.
• a foldable PET bottle comprising: a folding part including a plurality of horizontal folding lines and a plurality of vertical folding lines; the horizontal folding lines being formed in a manner such that each of them extends in a circumferential direction and they are spaced apart one from another by a predetermined interval in a vertical direction, and the vertical folding lines being formed in a manner such that each of them extends in the vertical direction and they are spaced apart one from another by a preselected angle in the circumferential direction, whereby the PET bottle can be folded and unfolded by the presence of the horizontal and vertical folding lines.
• the horizontal folding lines comprise horizontal depression lines and horizontal prominence lines which are alternately formed with each other, the horizontal depression lines ' being depressed inward upon folding of the folding part, and the horizontal prominence lines being prominent outward upon folding of the folding part.
• the vertical folding lines comprise vertical depression lines and vertical prominence lines which are alternately formed with each other, the vertical depression lines being depressed inward upon folding of the folding part, the vertical prominence lines being prominent outward upon folding of the folding part, and depressions and prominences of the vertical folding lines being alternated with each other in the circumferential direction in which the horizontal folding lines extend.

• a foldable PET bottle C has a body and a folding part.
• the folding part includes a plurality of horizontal folding lines 10 and a plurality of vertical folding lines 20.
• the horizontal folding lines 10 are formed in a manner such that each of them extends in a circumferential direction and they are spaced apart one from another by a predetermined interval in a vertical direction.
• the vertical folding lines 20 are formed in a manner such that each of them extends in the vertical direction and they are spaced apart one from another by a preselected angle in the circumferential direction.
• the horizontal folding lines 10 comprise horizontal depression lines 11 and horizontal prominence lines 12 which are alternately formed with each other.
• the horizontal depression lines 11 are depressed inward upon folding of the folding part, and the horizontal prominence lines 12 are prominent outward upon folding of the folding part.
• the vertical folding lines 20 comprise vertical depression lines 21 and vertical prominence lines 22 which are alternately formed with each other.
• the vertical depression lines 21 are depressed inward upon folding of the folding part, and the vertical prominence lines 22 are prominent outward upon folding of the folding part. Depressions and prominences of the vertical folding lines 20 are alternated with each other in the circumferential direction in which the horizontal folding lines 10 extend. In other words, if the PET bottle C is folded along the vertical folding lines 20 after being folded along the horizontal folding lines 10, depressions and prominences are produced on folding surfaces of the PET bottle C in the same directions.
• the horizontal folding lines 10 are formed to define zigzag patterns along the vertical depression lines 21 and vertical prominence lines 22. Thus, folding can be effected in a smooth manner at regions where the horizontal folding lines 10 and the vertical folding lines 20 are crossed with each other.
• the PET bottle C is carried or stored in a state wherein it is folded along the horizontal folding lines 10 and the vertical folding lines 20 into a predetermined size.
• the PET bottle C can be utilized in conformity with its use.
• FIGs. la through lc are perspective views sequentially illustrating folding operations of the PET bottle C
• FIGs. 3a through 3c are plan views sequentially illustrating folding operations of the PET bottle C
• FIGs. 4a through 4c are bottom views sequentially illustrating folding operations of the PET bottle C.
• the PET bottle C is pushed downward, the PET bottle C is folded in a multi-stepwise manner along the horizontal folding lines 10 in such a way as to be decreased in its height and along the vertical folding lines 20 in such a way as to be decreased in its width.
• the vertical folding lines 20 are arranged in a manner such that the vertical depression lines 21 and the vertical prominence lines 22 are positioned in the same directions, the volume of the PET bottle C can be reduced to the minimum.
• the PET bottle C because it is possible to reduce the volume of the PET bottle C by an amount by which the content is diminished, a space which is occupied by the PET bottle C, can be decreased, and, upon completion of the use, the volume of the PET bottle C can be minimized.
• the PET bottle according to the present invention may be made of synthetic resin, paper or other diverse materials .
• the foldable PET bottle according to the present invention provides advantages in that, since a plurality of horizontal folding lines each of which extends in a circumferential direction, are formed on a folding part of the PET bottle in such a way as to be spaced apart one from another by a predetermined interval in a vertical direction, and a plurality of vertical folding lines each of which extends in the vertical direction, are formed on the folding part of the PET bottle in such a way as to be spaced apart one from another by a preselected interval in the circumferential direction, the PET bottle can be folded and unfolded by the presence of the horizontal and vertical folding lines.
• the PET bottle can be carried in an easy manner and can be used in a convenient manner.
• the PET bottle can be discarded in a folded status after use, a bulk of a garbage bag can be remarkably decreased. Further, due to the fact that the PET bottle can be collected in a folded status for a recycling purpose after use, recycling of the PET bottle can be encouraged. Moreover, by the fact that distribution costs induced upon recycling can be reduced, economy is improved.
