Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a resin bottle.

[0002]

[Prior art]

 Conventional plastic bottles used to store carbonated drinking water are said to have a smooth surface around the circumference.

Therefore, the height cannot be easily changed, and as the contents are reduced, a large empty space is gradually formed inward. When the contents are carbonated drinking water, this empty space causes the carbonated water to escape from the drinking water, and significantly deteriorates the taste of the drinking water.

Further, since the process of flattening the main body, which is the container for the bottle, cannot be performed easily, when disposing as waste, it is generally handled in its original form, which is inconvenient because it is bulky.

[0005]

[Problems to be solved by the device]

 The present invention provides a resin bottle that can drink deliciously until it is consumed even if it is carbonated drinking water, saves the storage space, and does not become bulky as garbage. With the goal.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises a vertically long main body having an opening at the top and a lid for hermetically closing the opening, the main body being made of a resin material such as PETP and standing upright. It is characterized in that approximately 50% or more of the entire height of the peripheral surface portion is formed into a bellows body which can be shortened and deformed in the vertical direction. The height of the bellows-shaped body is shortened as the contents are consumed.

The present invention is specifically as follows. That is, a portion except for the upper and lower end portions of the standing circumferential surface portion is formed as a bellows body that can be shortened and deformed in the vertical direction, at least the upper portion of the standing circumferential surface portion is transparent, and the main body is integrally formed.

[0008]

[Embodiment of the invention]

 FIG. 1 is a front view of a resin bottle according to an embodiment of the present invention showing a partial cross section, FIG. 2 is an explanatory view showing a state in which the height of the bottle is reduced, and FIG. 3 is a height of the bottle. It is a figure which shows the state which made the minimum.

In these figures, 1 is a bottle body capable of sealing carbonated drinking water in a sealed manner, and 2 is a screw lid.

The main body 1 is a structure that can be integrally formed as a whole, and is formed of, for example, polyethylene or its copolymer (polyethylene terephthalate PETP).

The upright peripheral surface portion 3 of the main body 1 has an upper end portion 4 and a lower end portion 5 formed of smooth surfaces, and an intermediate portion thereof is a bellows-like body 6 which can be shortened and deformed in the vertical direction.

The bellows-like body 6 is provided over approximately 50% or more of the overall height of the standing peripheral surface portion 3 so that the overall height can be greatly shortened. Although the bellows-shaped body 6 in the illustrated example has a saw-tooth-shaped corrugated longitudinal section, the present invention is not limited to this, and the standing peripheral surface portion 3 can be deformed in a shortened manner without the transverse sectional shape of the standing peripheral surface section 3 being greatly disturbed. Any form may be used as long as it is one.

Further, it is preferable that the entire standing circumferential surface portion 3 can be seen through, or at least the upper portion thereof can be seen through.

An example of using the product of the present invention configured as described above will be described. The main body 1 is fully filled with a contained product w such as juice or carbonated drinking water in a state where it has a normal height as shown in FIG. 1, and then the screw lid 2 is screwed in an airtight manner.

The contents w contained in the bottle in this state decrease every time it is consumed, and the empty space inside the bottle in the state of the normal height gradually increases.

Therefore, every time the consumer w consumes the contents w, the upper portion of the main body 1 is left open with the opening portion 7 open so that the empty space of the main body 1 having the normal height shown in FIG. Is pressed down to reduce the height of the bellows-shaped body 6. During this shortening operation, since the bellows-like body 6 does not change its cross-sectional area largely, the inner volume of the main body 1 is gradually reduced, and the opening 7 moves toward the upper surface of the contents w. . This movement is visually confirmed through the see-through main body 1 or its upper part.

When the opening 7 approaches the upper surface of the article w in this manner, the pushing down of the upper part of the main body 1 is stopped, and the screw lid 2 is airtightly screwed to the opening 7 while maintaining this stopped state. After this, even if the pushing-down force to the main body 1 is removed, the total length of the bottle hardly changes due to the airtightness inside and the non-expansion of the contents (water etc.) It will be held at the appropriate length.

Therefore, in the process of consuming the contents w of the bottle, a large empty space is not formed inside thereof, especially when the contents w are carbonated drinking water. Since a large amount of carbonic acid in drinking water does not escape into the empty space s, the carbonated drinking water can be eaten and drink deliciously until it is consumed. In addition, bottles with a shorter overall length can be conveniently stored even on a shelf with a low height or in a box with a shallow depth.

In this way, when the contents of the bottle are exhausted and the bellows-shaped body 6 is shortened to the shortest state as shown in FIG. 3, the bottle is no longer likely to be shortened any more, and the waste is This is the shortest state when processed as. This makes the bottle less bulky and facilitates subsequent processing.

[0020]

[Effect of the invention]

 According to the present invention configured as described above, the total height of the bottle can be shortened according to the consumption amount of the contents, and therefore it is convenient even on a shelf with a low height or in a box with a shallow depth. In addition to being able to be stored in a container, the volume of the waste when it is discarded becomes extremely small, and the processing can be performed efficiently.

[0021] Also, the contents can be poured in and taken out in the same manner as before, and convenience is not impaired. Moreover, since the empty space in the bottle can be reduced, when the contents are carbonated drinking water. In addition, it is possible to prevent the carbonated water from coming out of the drinking water, and it is possible to drink and drink the carbonated drinking water until it is consumed.

According to the third aspect of the present invention, the upper and lower end portions of the upright peripheral surface portion retain their shape retainability and are easy to handle, and according to the fourth aspect, It is now possible to visually confirm that the upper surface of the contents inside the main body has approached the opening of the main body, which allows convenient operation of shortening the height of the main body.

According to the fifth aspect, the main body can be manufactured at low cost, and the airtightness can be easily ensured.
