JP2002249138A - Pet bottle and attachment for spout of bottle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To quickly and stably pour liquid without splattering stably when pouring the liquid from a PET bottle or a glass bottle, and to cap the bottle again when the liquid remains in the bottle. SOLUTION: As the uncapped PET bottle or the glass bottle containing the liquid is slowly tilted horizontally to an angle of 90 deg. from the upstanding state, liquid comes out, air is sucked into a container, and the sucked air is accumulated in the vessel. The part in the vessel within a 3 cm radius around the part in which the sucked air staying at first is formed as an air trap. An attachment attached on the inside of the spout or neck of the PET bottle or glass bottle is fitted to a pipe connecting the air trap and the part within a 3 cm radius around a spout of the PET bottle or glass bottle.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for stabilizing an outflow of liquid when pouring liquid from a plastic bottle and a bottle.

[0002]

2. Description of the Related Art Conventionally, in plastic bottles and bottles having a narrow spout, the internal pressure is reduced when the contents flow out. At this time, due to the thinness of the spout and the viscosity of the liquid, air cannot be continuously sucked from the outside and if the inside has a constant pressure, the air is collectively sucked from the outside.
Each time, the amount of outflow changes and increases and decreases repeatedly. For this reason, it takes a long time to pour, and it is very inconvenient to continuously splash or spill.

[0003]

The object of the present invention is to stabilize the amount of liquid when pouring liquid from PET bottles and bottles, so that the liquid can be poured quickly and without splashing. Made it possible to close the lid again.

[0004]

In order to solve the above-mentioned problem, the spout (1) is divided by a partition (2) such as the side of a pipe, and the liquid is sucked separately from the part from which the liquid flows out. It is necessary to have an airway through which only air passes, i.e. the tube (3), and to connect this airway to the portion of the container where the aspirated air quickly accumulates.

[0005] Further, it is necessary to provide a structure in which the lid can be tightened while the device is mounted, or a structure which can be quickly attached and detached.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS This is shown in FIGS.
This is explained using a tube with a fastener.

First, a stopper is adjusted according to the inner diameter of the spout (1) or neck (5) of the plastic bottle and bottle so that the pipe (3) can be fixed to the spout of plastic bottle and bottle. Attach (4).

The pipe (3) is bent along the spout (1) of the bottle and bottle and the neck (5) and the shoulder (6). ) And the side (7) are connected to a portion (3) within 3 cm of the portion (10).

An annular stopper (11) covering the upper part of the spout is attached to the upper part of the stopper (4).

[0010] Furthermore, a bezel (12) is attached to the lower part of the bezel (4) along the neck (5) and shoulder (6) of the plastic bottle and bottle.

A flow rate adjusting plate (9) for narrowing the spout (1) is attached to the stopper (4) or (11).

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When the tip of the tube (3) having the above structure is used for a cylindrical container such as a bottle, a portion (10) where a shoulder (6) and a side surface (7) are joined, or Insert it into the air pool (14).

When used in a prismatic container such as a PET bottle, a joint (10) where a joint between adjacent side surfaces is joined to a shoulder (6) or an air pocket (1).
Insert the tip of the tube (3) towards 4).

The stopper (4) serves to fix the pipe (3) so that it does not rotate inside the spout (1) or the neck (5).

The stoppers (11) and (12) serve to fix the pipe (3) so that it does not move up and down.

Thereby, the pipe (3) is fixed inside the spout (1).

The container is tilted so that the tip of the tube inserted into the container is directly above, and the liquid content is poured into a cup or the like.

[0018]

When the liquid flows out, the pressure in the container decreases, and air is sucked from the pipe (3).

The sucked air collects at the distal end of the tube (3) inserted into the container.

At this time, even if the liquid has entered the inside of the pipe (3), the liquid is sucked inside the container by the pressure difference, and the airway is secured.

Since the airway is ensured, air can be continuously sucked, and the outflow of the liquid to be poured is stabilized.

When adjusting the outflow amount, the outflow amount can be adjusted by changing the size of the flow control plate (9).

After pouring, if the lid is closed as usual, the stopper (11) is interposed between the lid (13) and the spout (1), the airtightness is maintained, and the container can be hermetically sealed.
