Abstract

(57) Abstract: [PROBLEMS] To provide a plastic bottle for beverage, which can be easily crushed to reduce the volume when the beverage inside is empty. SOLUTION: The front wall 1 and the rear wall 2 have a flat transverse cross-sectional shape in which the width dimension W is larger than the width dimension D of the left and right side walls 3, 4, and the front wall 1 and the rear wall 2 are vertically arranged. Is curved (straight) in the same direction in the width direction. Therefore, it is easily crushed. The storage space for garbage is small and transportation efficiency is good. Since it is easy to take out when the contents are empty, it is less likely to be discarded as garbage.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a plastic bottle containing a drink such as drinking water, carbonated drink or juice.

[0002]

[Prior art]

 In recent years, PET (polyethylene terephthalate) bottles have been widely used for selling beverages. Conventional PET bottles for beverages generally have a circular cross section or a square cross section.

[0003]

[Problems to be solved by the device]

 PET bottles are light, durable, and convenient, but they have the drawback that they become very bulky when the contents (beverage) are empty. For this reason, when a PET bottle is taken out as garbage, it requires a large space for storage, and when it is carried as garbage, it is bulky and transport efficiency is poor. In addition, if you take a PET bottle for hiking or the like and the contents are empty, it is so bulky that it is difficult to take it home and is often thrown in the mountains as garbage.

In view of the above problems, an object of the present invention is to provide a plastic bottle for beverages, which can be easily crushed to reduce its volume when the beverage therein is empty. .

[0005]

[Means for Solving the Problems]

 The beverage plastic bottle of the present invention has a flat cross-sectional shape in which the width dimension of the front wall and the rear wall is larger than the width dimension of the left and right side walls, and the front wall and the rear wall do not bend upward and downward. It is characterized in that it is curved in the same direction in the width direction.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 3 show a PET bottle for beverage which is an embodiment of the present invention. In the figure, 1 is a front wall of a bottle, 2 is a back wall, 3 is a left side wall, 4 is a right side wall, 5 is a bottom wall, 6 is a top wall, 7 is a beverage inlet / outlet port, and 8 is an uneven portion for reinforcement. is there.

As shown in FIG. 3, this PET bottle has a flat cross-sectional shape in which the width W of the front wall 1 and the back wall 2 is larger than the width D of the left and right side walls 3, 4. The front wall 1 and the rear wall 2 are not curved in the vertical direction (straight) but are curved in the same direction in the width direction. "Curved in the same direction" means that the concave surface of the front wall 1 (outer surface in the illustrated example) and the concave surface of the rear wall 2 (inner surface in the illustrated example) face in the same direction as shown in FIG. It means that there is.

Since the peripheral wall of this PET bottle has the above-mentioned shape, when the beverage inside is empty, the center portion of the front wall 1 is indicated by an arrow P in FIG. 3 with the thumbs of both hands. When it is pressed to, it is easily deformed as shown in FIG. 4, and when it is further pressed in the direction of arrow Q from the state of FIG. 4, it is crushed as shown in FIG. In this way, this PET bottle can be easily crushed to reduce the volume, so that a small storage space is required when it is taken out as garbage, and the efficiency of transportation as garbage is good. Also, if you take it on a hike or the like and it becomes empty, you can easily crush it and put it in your backpack or take it home with you. Therefore, it is less likely to be dumped in Yamano.

[0009]

[Effect of the invention]

 As described above, the beverage plastic bottle of the present invention can be easily crushed to reduce the volume when the beverage inside is empty, which is convenient for taking out the garbage. Also, when you take it on a hike, empty bottles are easy to take home, so it is less likely to be thrown into the mountains as garbage.
