Abstract

<P>PROBLEM TO BE SOLVED: To provide a plug device of a PET bottle which is capable of opening and closing the plug only by pulling/inserting a lid part and pushing a pressing piece, in a container having a flange part between an opening part and a neck part. <P>SOLUTION: The pressing piece 3 which resiliently presses the lower surface of the flange part of the PET bottle of a plug to be closed is turnably hinged and connected at any position on a top surface of the outer wall of the lid part 1 via a hinge connecting part 2. As a result, when the lid part 1 covers the opening part 7 of the PET bottle 5 and the pressing piece 3 is pushed below the lower surface of the flange part 6 of the PET bottle 5, the pressing piece 3 turns on the hinge connecting part 2 as a turning axis and closes the plug by clamping the top surface of the outer wall of the cover part 1 and the lower surface of the flange part 6 of the PET bottle 5 and resiliently pressing them. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention relates to a stopper device for a PET bottle and a stopper device for a container such as a bottle or a water bottle having a collar portion between a mouth portion and a neck portion.

The lid part of commercially available PET bottles with beverage foods is screwed, and the PET bottle mouth cannot be opened or closed unless the lid part is turned many times, which is inconvenient when drinking beverage foods. Met.

As countermeasures, Patent Document 1 discloses a technique for opening and closing the lid with a hinge, Patent Document 2 discloses a technique for opening and closing the lid with a slide, and Patent Document 3 discloses a technique for opening the lid with a nozzle. A technology that opens and closes with the above is disclosed.
JP 2004-306981 A JP 2005-82199 A JP 2005-132478 A

However, both of these techniques are inconvenient when replacing the plastic bottle because the attachment part to the mouth of the plastic bottle is screwed in and cannot be attached or detached unless the attachment part is turned many times. .

SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, the present invention provides a stopper device for a PET bottle that can be easily opened and closed, eliminates the inconvenience when drinking beverage foods in a small amount, and replaces the PET bottle. The purpose is to eliminate the inconvenience.

The stopper device for a PET bottle according to the present invention is hinged to a pressing piece that elastically presses the lower surface of the collar portion of the PET bottle to be closed at an appropriate position on the top surface of the outer wall of the lid.

The PET bottle stopper device of the present invention configured as described above covers the lid portion on the mouth portion of the PET bottle to be closed, and pushes the pressing piece into the lower surface of the collar portion of the PET bottle. The pressing piece rotates about the hinge coupling portion as a rotation shaft, and elastically presses and closes the outer wall top surface of the lid portion and the lower surface of the collar portion of the PET bottle.

Next, by pressing the pressing piece away from the lower surface of the collar portion of the PET bottle, the pressing piece rotates about the hinge coupling portion as a rotation axis, and the outer wall top surface of the lid portion by the pressing piece and the The lid portion, which has been released from the bottom surface of the collar portion of the plastic bottle and can be freely inserted and removed, is removed from the mouth portion of the plastic bottle and opened.

Thus, according to the PET bottle stopper device of the present invention, since it can be easily opened and closed simply by removing and inserting the lid and pushing the pressing piece, it eliminates the inconvenience when drinking beverage foods. Inconvenience when replacing plastic bottles is also eliminated.

The stopper device for a plastic bottle of the present invention may be a stopper device for a container such as a bottle or a water bottle having a collar between the mouth and the neck, and in the same manner as described above, the lid is inserted and removed. It can be opened and closed easily just by pushing a single piece.

In the above, the pressure piece is moved by fixing a container such as a bottle or a water bottle having a collar between the plastic bottle or the mouth and the neck, but the pressure piece is fixed between the plastic bottle or the mouth and the neck. It is the same even if a container such as a bottle or a water bottle having a collar is moved, and a hinged coupling part and a container such as a bottle or water bottle having a collar between the mouth part and the neck part are connected. Opening and closing can be done easily only by the rotation of the rotation axis.

In FIG. 1, a pressing piece 3 that elastically presses the bottom surface of the lid of a PET bottle to be closed is pivoted through a hinge coupling portion 2 at an appropriate position on the top surface of the outer wall of the lid portion 1. Join.

Since it was set as such a structure, as shown in FIG. 2, the cover piece 1 is put on the mouth part 7 of the plastic bottle 5, and the pressing piece 3 is pushed into the lower surface of the collar part 6 of the plastic bottle 5, whereby the pressing piece 3 is As shown in FIG. 3, the hinge coupling portion 2 is rotated about a rotation axis, and is elastically pressed and plugged between the top surface of the outer wall of the lid portion 1 and the lower surface of the collar portion 6 of the plastic bottle 5.

Next, in FIG. 3, when the pressing piece 3 is pushed away from the lower surface of the collar part 6 of the plastic bottle 5, the pressing piece 3 rotates about the hinge coupling part 2 as a rotation axis, and as shown in FIG. The cap 1 between the outer wall top surface of the lid portion 1 and the lower surface of the collar portion 6 of the plastic bottle 5 by the piece 3 is released, and the lid portion 1 that can be inserted and removed is removed from the mouth portion 7 of the plastic bottle 5 and opened.

As described above, since it can be easily opened and closed by simply inserting and removing the lid portion 1 and pushing the pressing piece 3, it is possible to eliminate the inconvenience when drinking beverage food and to replace the plastic bottle 5. Inconvenience is also eliminated.

In FIG. 4, the outer wall side surface of the lid portion 1 is positioned at an appropriate position of the pressing piece 3 of the first embodiment, with the pressing piece 3 being pushed away from the lower surface of the collar portion 6 of the PET bottle 5 as shown in FIG. 2. By attaching the stopper piece 4 that stops when the stopper piece 4 stops, the pressing piece 3 is pushed away from the lower surface of the collar portion 6 of the plastic bottle 5 with an easy operation of pressing the stopper piece 4 against the side surface of the outer wall of the lid portion 1. In addition to opening the plug, the pressing piece 3 can be prevented from being separated too far from the outer wall side surface of the lid 1.

In FIG. 5, by attaching a gripping tool 8 for gripping and fixing a bicycle frame part, a handle part or the like to an appropriate position of the pressing piece 3 of Example 1, the insertion / extraction of the plastic bottle to be closed and the hinge coupling part are Opening and closing can be done easily only by the rotation of the rotation axis.

It is a perspective view which shows the Example of the stopper apparatus of this invention. It is a side view which shows the state which covered the plastic bottle same as the above. It is a side view which shows the state which closed the plastic bottle same as the above. It is a perspective view which shows the Example which attached the stopper piece to the stopper apparatus shown in FIG. It is a perspective view which shows the Example which attached the holding tool to the stopper apparatus shown in FIG.
