Description

  The present invention relates to a plastic bottle that can smoothly pour drinking water by preventing the splashing of the drinking water due to a pressure difference between the inside and the outside of the bottle when pouring drinking water from the plastic bottle.

In recent years, PET bottles made of polyethylene terephthalate have been widely used as drinking water containers instead of bottles because of convenience during transportation and resistance to cracking. On the other hand, when drinking water from a plastic bottle is poured into a cup, the drinking water flows backward due to the pressure difference between the inside and outside of the bottle, so the outflow amount changes greatly. As a result, the drinking water can be poured smoothly. Have been forced to not. In particular, carbonated beverages and the like increased in foaming by flowing backward, and often contaminated the surroundings by splashing.
In order to solve such a problem at the time of water injection, an invention described in JP-A-2002-249138 has been proposed. In the invention described in the publication, the internal gap (air reservoir) generated when the PET bottle is tilted and the spout are connected by a pipe, and air is introduced into the bottle at the time of injecting drinking water, It is possible to pour drinking water smoothly.

However, since the invention described in Patent Document 1 has a detachable stopper at the spout of the PET bottle, when it is used repeatedly, dirt or the like adheres to the stopper and germs propagate. There was a risk of problems in hygiene. In addition, since the invention described in Patent Document 1 uses a tube (straw) with air taken in to a stopper as a member for taking in air, it can be taken in depending on the inclination angle and the tilting speed of the plastic bottle. There are cases where the amount of air is insufficient and the drinking water cannot be poured smoothly.
Furthermore, the invention of Patent Document 1 is used in a state of being fitted into the spout, and since it is not bonded to the bottle body, it is easily damaged, and accidents such as accidental ingestion may occur. Conceivable.

  The present invention has been proposed to deal with such various circumstances, and when pouring drinking water from a plastic bottle, it can be poured smoothly without splashing, and various bacteria etc. An object of the present invention is to provide a PET bottle that can be used hygienically and safely without the risk of breeding.

In order to achieve the above object, the invention according to claim 1 is a plastic bottle in which an air reservoir is formed on the inner upper side when the drinking water accommodated therein is tilted when tilted. An air intake passage for supplying air from a spout to the air reservoir is formed by attaching a cylindrical portion forming member that forms a passage on the inner wall surface of the bottle.

The invention according to claim 2 is a plastic bottle in which an air reservoir is formed in the upper part of the inside when the drinking water contained therein is inclined when tilted, and a passage is formed from the spout to the inner wall surface inside the bottle. By attaching the cylindrical part forming member to be formed, an air intake passage for supplying air from the spout to the air reservoir is formed, and an opening facing the air reservoir of the air intake passage is formed in a divergent shape. It is characterized by that.

The invention according to claim 3 is a plastic bottle in which an air reservoir is formed in the upper part of the inside by drinking water contained therein when tilted, and a passage is formed from the spout to the inside of the wall inside the bottle. By attaching the cylindrical part forming member to be formed, an air intake passage for supplying air from the spout to the air reservoir is formed, and the cylindrical part forming member forms a flat part to be attached to the inside of the spout. It is characterized by that.

As described above, according to the first to third aspects of the present invention, by attaching the tubular portion forming member that forms the passage from the spout to the inside of the wall inside the bottle, air is supplied from the spout to the air pool in the bottle. An air intake passage for supplying air is formed. For this reason, while pouring the amount of water that flows from the spout at the time of pouring, it is possible to pour drinking water smoothly without backflowing. Moreover, since the cylindrical part formation member which forms an air intake passage is previously attached inside the wall surface, it can be used hygienically and safely.

  In particular, according to the second aspect of the invention, the opening of the air intake passage facing the air reservoir is formed in a divergent shape, so that the portion facing the air reservoir is enlarged, so that it is inclined. Even if a slight deviation occurs in the direction, air can be reliably introduced into the air reservoir. In addition, it is possible to smoothly take in air into the air reservoir when pouring drinking water.

  In particular, according to the third aspect of the present invention, the portion attached to the spout portion of the tubular portion forming member is formed flat. For this reason, when bottling drinking water into a plastic bottle at a drinking water manufacturing factory, the air intake passage does not get in the way, and the drinking water can be injected smoothly.

Hereinafter, a plastic bottle according to the present invention will be described with reference to the accompanying drawings. 1 is a schematic perspective view of a plastic bottle according to one embodiment of the present invention, FIG. 2 is a schematic side view of the plastic bottle according to the present embodiment, and FIG. 3 is a side view showing a state in which the plastic bottle is tilted. FIG. 5 is a plan view of a plastic bottle according to the present embodiment, FIG. 5 is a front view of the plastic bottle according to the present embodiment, and FIG. 6 is a cross-sectional view of a main part of the plastic bottle according to the present embodiment.

As shown in FIGS. 1 and 2, the plastic bottle 10 of the present embodiment is provided with an air intake passage 14 at a portion of the spout 12. As shown in FIGS. 4 to 6, the air intake passage 14 has a cross-sectional shape in which a portion attached to a portion of the upper spout 12 is flat, and a lower oblique portion is formed in a substantially semicircular arc shape. It is formed by attaching the cylindrical part forming member 16 in a curved state along the inner wall surface of the bottle from the portion of the spout 12. Thus, by flattening the shape of the cylindrical portion forming member 16 near the spout 12, when the drinking water is bottled, the air intake passage 14 does not get in the way, and the drinking water is smoothly poured into the PET bottle 10. Can be injected into.

As a method of attaching the tubular part forming member 16 to the wall surface, welding the tubular part forming member 16 may be considered. Moreover, the cylindrical part formation member which forms the air intake channel | path 14 can utilize the polyethylene terephthalate which is the same material as a PET bottle, or can utilize another material suitable for the attachment to a wall surface. .

When the drinking water in the plastic bottle 10 is poured into a glass or the like, the plastic bottle 10 is tilted. At that time, the drinking water A is also tilted at the same time, and as shown in FIG. B is produced. The lower opening 14 </ b> A of the air intake passage 14 opens to the air reservoir B, introduces air from the intake 14 </ b> B of the spout 12 of the bottle 10, and allows air to enter the air reservoir B through the air intake passage 14. It can be introduced. As a result, the pressure inside the bottle 10 can be brought close to the outside pressure, and the drinking water contained therein can be poured smoothly from the spout 12 into a glass or the like with a constant amount of water.
