DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a closed container,
In particular, the present invention relates to a mounting structure of a stopper for sealing the inside of a bottle container.

[0002]

In general, bottle containers that need to be kept hermetically sealed, such as bottle containers for alcoholic beverages (beer, shochu, etc.) and soft drinks, and water bottles are shown in FIG. In some cases, an antique style mechanical stopper provided with a frame-shaped metal fitting called a swing stopper for fixing the stopper 1 to the bottle opening B 'of the bottle container B is used.

The swing stopper 2 is composed of a metal upper frame 2A inserted into a through hole 1a formed horizontally in the center of the stopper 1 and a bottle container B connected to the upper frame 2A at both ends. And a lower metal frame 2B rotatably fitted to a pair of connection holes Ba formed in the side wall surface of the bottle B ′.

The upper frame 2A comprises a horizontal portion 2Aa penetrating through the through hole 1a of the plug 1, and a pair of arm portions 2Ab extending from both ends of the horizontal portion 2Aa in a direction substantially perpendicular to the horizontal portion 2Aa. A hook 2Ac is formed at the tip of the upper arm 2Ab so as to be bent inward.

[0005] The lower frame 2B includes a lever portion 2Ba formed in an arc shape, a ring portion 2Bb formed by bending both ends of the lever portion 2Ba into a circular shape, and a lever portion 2Ba from the ring portion 2Bb. The lower arm 2Bc extends in a direction substantially perpendicular to the lower arm 2Bc, and a hook 2Bd is formed at an end of the lower arm 2Bc so as to be bent inward.

The upper frame 2A and the lower frame 2B
Is a pair of hooks 2Ac of the upper frame 2A
B are connected to each other by being relatively rotatably fitted to the pair of ring portions 2Bb from the outside, and a pair of hook portions 2Bd of the lower frame 2B are formed on the side wall surface of the bottle container B. Are connected to the bottle container B by being rotatably fitted to the connection holes Ba.

The swing stopper 2 is connected so that the stopper 1 does not separate from the bottle container B even when the stopper 1 comes off from the bottle opening B 'of the bottle container B, as shown by a two-dot chain line in FIG. doing.

When the bottle B is sealed, the stopper 1 is used.
After fitting the cork portion 1A into the opening of the bottle opening B ′, the lever portion 2Ba of the lower frame 2B is turned downward from the vertically upward state shown by the two-dot chain line in FIG. In the horizontal direction as shown by the solid line, the upper frame 2A connected to the lower frame 2B
The upper arm 2Ab is positioned in the vertical direction shown by the solid line, and is pulled downward by the lower arm 2Bc of the lower frame 2B, so that the stopper 1 is moved further into the opening of the bottle opening B '. Forced and firmly fixed.

[0009] Contrary to the above operation, the lower frame 2
By pulling the lever 2Ba of B upward from the horizontal state shown by the solid line in FIG. 8 in the upward direction, the pulling state of the plug 1 by the upper arm 2Ab is released. It can be pulled out from the opening of B '.

The stopper of the type fixed by the swing stopper 2 as described above has been used for a long time because of its superiority in design, hermeticity of the container and easy opening operation.

However, the swing stopper 2 requires considerable strength to fix the stopper 1 to the bottle opening B 'of the bottle B, and therefore, the lower frame 2 Is required to fit the hook portion 2Bd into the connection hole Ba in the side wall of the bottle B ′.
The mounting work to the bottle container B is troublesome and the production efficiency cannot be increased.

In recent years, the recycling of recyclable waste has been promoted, and when the bottle B with the swing stopper 2 is taken out for waste collection, a glass bottle B and a metallic swing are used. -Although the stopper 2 must be separated from the bottle container B, it is difficult to remove the swing stopper 2 from the bottle container B. Therefore, recycling of the bottle container B having the swing stopper 2 has been performed so far. Not.

Further, the conventional swing stopper 2
As shown in FIGS. 7 and 8, the horizontal portion 2Aa of the upper frame 2A is not separated from the plug 1 by being inserted into the through hole 1a of the plug 1. After the wire is inserted into the through-hole 1a of the plug 1, both sides of the wire must be bent and formed into a predetermined shape, so that the manufacturing efficiency is very low.

Furthermore, a swing stopper 2 made of metal
Since it is difficult to separate the stopper 1 from the swing stopper 2 when recycling the same, the recycling of the swing stopper 2 has not been promoted.

The present invention has been made to solve the above-mentioned problems in a bottle container having a swing stopper for fixing a stopper.

That is, a first object of the present invention is to provide a sealed container in which a swing stopper can be easily attached and detached.

It is a second object of the present invention to provide a sealed container in which a stopper can be easily attached to and detached from a swing stopper.

[0018]

According to a first aspect of the present invention, there is provided an airtight container, comprising: a first frame-shaped frame having one side rotatably connected to a stopper; The pair of arms are connected to each other by rotatably fitting into a pair of connection holes formed on the outer wall surface of the container, and the pair of arms are integrally connected to each other. A second frame including a frame portion extending outwardly in a plane perpendicular to the second frame; the other side of the first frame is rotatably connected to a connection portion between the arm portion and the frame portion of the second frame; And a swing stopper that locks while the first frame is pulled downward by rotating the arm by pulling down the frame of the second frame with the stopper attached to the mouth of the container. A closed container provided with a groove extending in a substantially horizontal direction at a position adjacent to at least one of a pair of connection holes in an outer wall surface of the container and into which a distal end of an arm of a second frame is slidably fitted. Is formed, and one end of the groove portion is communicated with the connection hole, and the height of the inner wall surface of the connection hole at the connection portion between the connection hole and the groove portion is lower than other portions. .

In the closed container according to the first aspect of the present invention, after the stopper is attached to the mouth of the container, the frame portion of the second frame of the swing stopper 2 is pushed down to pull the first frame downward. Locked in the state
The stopper is fixed in a state in which the stopper is in close contact with the mouth of the container. Conversely, the locked state of the first frame is released by raising the frame portion of the second frame.

When attaching the swing stopper to the container, the tip of one arm of the second frame is fitted into one of the connection holes, and then the tip of the other arm is connected to the other. Of the groove formed so as to communicate with the connection hole of the other side, and is slid along the groove in the direction of the connection hole to fit the other connection hole. At this time, the tip of one arm of the second frame is guided by the groove in the direction of the connection hole, and the height of the inner wall surface at the connection between the connection hole and the groove becomes lower than the other portion. As a result, the distal end portion of the arm portion is securely fitted into the connection hole without significantly bending.

When the swing stopper is detached from the container, the arm of the second frame, the tip of which is fitted in the connection hole on the side where the groove is formed, is pulled in the direction of the groove. The tip of the part rides into the groove from the connection hole, slides along the groove, and finally leaves the groove. At this time, since the height of the inner wall surface of the connection hole at the connection portion with the groove portion is lower than the other portions, the fitted state between the distal end portion of the arm portion and the connection hole is easily released.

As described above, according to the closed container according to the first aspect of the present invention, at least one of the pair of connection holes of the container to which the swing stopper is connected has a groove communicating therewith. Since the height of the inner wall surface of the connection hole at the connection portion is lower than the other portions, the swing stopper can be easily attached to and detached from the container. In addition, this makes it possible to significantly improve the production efficiency of the sealed container, and also allows the swing stopper to be easily removed from the container at the time of disposal. Is promoted.

According to a second aspect of the present invention, in order to achieve the first object, in addition to the configuration of the first aspect, the depth of the groove extends from the connection hole side to the other end side. It is characterized by being shallower according to.

In the sealed container according to the second aspect of the present invention, when the swing stopper is attached to the container, the distal end of the arm portion of the second frame fitted in the groove slides in the direction of the connection hole along the groove. At this time, since the depth of the groove is gradually increased, the groove is guided toward the bottom of the connection hole. When the swing stopper is removed from the container, the distal end of the arm that is disengaged from the connection hole and slides in the groove is oriented in the direction of the outer surface of the container because the depth of the groove is gradually reduced. I will be guided to. As a result, the distal end of the arm portion of the second frame is smoothly guided in a direction approaching the connection hole or in a direction away from the connection hole, so that the swing stopper can be more easily attached to and detached from the container. I can do it.

According to a third aspect of the present invention, in order to achieve the second object, in addition to the configuration of the first aspect, the first frame has both ends formed on the outer wall surface of the stopper. The plug is connected to the pair of connection holes by being rotatably fitted to each other, and extends in a substantially horizontal direction at a position adjacent to at least one of the pair of connection holes on the outer wall surface of the plug, and a distal end portion of the first frame. Is formed so that one end of the groove communicates with the connection hole, and the height of the inner wall surface of the connection hole at the connection portion between the connection hole and the groove is higher than other portions. It is characterized by being low.

In the closed container according to the third aspect of the present invention, as in the case of the second frame of the swing stopper, the first frame is turned around a pair of connecting holes formed on the outer wall surface of the stopper. It is connected to the stopper by being movably fitted.

When attaching the swing stopper to the stopper, one end of the first frame is fitted into one connection hole, and then the other end is communicated with the other connection hole. The thus formed groove is fitted to the end opposite to the connection hole side, and is slid along the groove in the direction of the connection hole to fit the other connection hole. At this time, the front end of the first frame is guided by the groove in the direction of the connection hole, and the height of the inner wall surface at the connection portion of the connection hole with the groove is lower than the other portions. The distal end of the frame is fitted into the connection hole without being greatly bent.

When the swing stopper is removed from the stopper, the tip of the first frame whose tip is fitted into the connection hole on the side where the groove is formed is pulled in the direction of the groove. The leading end of one frame rides in the groove from the connection hole, slides along the groove, and finally separates from the groove. At this time, since the height of the inner wall surface of the connection hole at the connection portion with the groove portion is lower than other portions, the fitted state between the distal end portion of the first frame and the connection hole is easily released.

As described above, according to the sealed container according to the third aspect of the present invention, the swing stopper can be easily attached to and detached from the stopper, thereby significantly improving the production efficiency of the sealed container. At the same time, at the time of disposal, the metal swing stopper and the stopper made of a material other than metal can be easily separated, thereby promoting the recycling of resources.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of the embodiment of the present invention. The structure of the swing stopper 2 is the same as that of the conventional one shown in FIGS. I have.

In FIG. 1, the bottle B of the bottle container B1
A connection hole B1a into which one hook portion 2Bd of the lower frame 2B of the swing stopper 2 is fitted is formed on the outer peripheral surface of 1 '.
A connection hole B1b into which the other hook 2Bd 'is fitted;
A groove B1c formed to communicate with the connection hole B1b
Are formed.

The connection hole B1a and the connection hole B1b are arranged as shown in FIG.
As shown in the enlarged view, each axis is formed so as to face the center of the bottle B1 'with the center of the bottle B1' interposed therebetween.

As can be seen from FIGS. 2 and 3, the groove B1c extends from the connection hole B1b in the counterclockwise direction in the figure along the circumferential direction of the outer peripheral surface of the bottle opening B1 '.
It is formed so that the depth becomes shallower toward the tip.
The direction in which the groove B1c extends is set to be opposite to the brand name display side (the left side in FIGS. 2 and 3) of the body of the bottle container B.

Note that the direction in which the groove B1c extends is not strictly a circumferential direction, and may be inclined so as to rise or fall toward the tip. Further, it may extend in the clockwise direction in the figure.

At the connection portion S between the connection hole B1b and the groove B1c, the depth of the connection hole B1b is reduced by opening the inner wall surface of the connection hole B1b toward the groove B1c.

When attaching the stopper 1 to this closed container,
The stopper 1 and the swing stopper 2 are positioned on the side opposite to the brand name display side of the bottle B, and one hook 2Bd of the lower frame 2B is fitted into the connection hole B1a of the bottle B1 '. The other hook 2Bd 'is slid forward from the back of the bottle bottle B1' along the groove B1c to form the groove B1 '.
c is fitted into the connection hole B1b located at the front end (the state shown by the two-dot chain line in FIG. 3).

When the hook 2Bd 'is fitted into the connection hole B1b, the hook 2Bd' of the swing stopper 2 is inserted into the groove B1c whose distance from the connection hole B1a is smaller than the outer peripheral surface of the bottle B1 '. Since the lower frame 2B passes through and moves in the direction of the connection hole B1b, there is no need to flex the lower frame 2B to greatly expand the space between the hooks 2Bd and 2Bd 'on both sides as in the related art. The swing stopper 2 can be easily attached without any additional work.

When the bottle B is discarded, the hook 2Bd 'of the lower frame 2B is pulled rearward of the bottle B to release the fitting state with the connection hole B1b, contrary to the above operation. After sliding back along the groove B1c to separate it from the bottle opening B1 ', the other hook 2Bd is pulled out from the connection hole B1a, and the stopper 1 and the swing stopper 2 are removed from the bottle container B.

At this time, since the depth of the connection hole B1b is small at the connection portion S between the connection hole B1b and the groove B1c, the connection hole B is not greatly bent without bending the lower frame 2B.
The hook portion 2Bd 'can be pulled out from 1b, so that the swing stopper 2 can be easily removed from the bottle container B.

When the stopper 1 is fixed to the bottle opening B 'of the bottle B by the swing stopper 2, as shown in FIG. 1, the upper arm 2Ab of the upper frame 2A and the lower arm 2B of the lower frame 2B are fixed. Since the portion 2Bc is oriented substantially vertically and the hooks 2Bd and 2Bd 'are pulled substantially vertically upward, the hook 2Bd' is connected to the connection hole B1b.
Is engaged with the inner wall surface on the upper side where the depth is deep. Therefore, there is no possibility that the swing stopper 2 comes off the bottle B when the stopper 1 is fixed.

FIGS. 4 to 6 show another embodiment of the closed container according to the present invention. The structure of the bottle container B is the same as that of the above-described examples of FIGS. Reference numerals are given.

In FIG. 4, the swing stopper 20
Is composed of an upper frame 20A and a lower frame 20B. The upper frame 20A includes a lever portion 20Aa formed in an arc shape, and an upper arm portion 20Ab rising substantially perpendicularly from both ends of the lever portion 20Aa. Hook portions 20Ac and 20Ac 'bent inward are formed at the tip of the upper arm portion 20Ab.

The shape of the lower frame 20B is substantially the same as that of the example of FIGS.
Ba, a ring portion 20Bb, a lower arm portion 20Bc, and hook portions 20Bd and 20Bd '.

The upper frame 20A and the lower frame 20B
Are the lever 20Aa of the upper frame 20A and the upper arm 2
0Ab is connected to the ring 20B of the lower frame 20B.
b, they are connected to each other so as to be rotatable relative to each other.

On the outer peripheral surface of the stopper 10, a connecting hole 10a into which one hook portion 20Ac of the upper frame 20A of the swing stopper 2 is fitted, and a connecting hole 10b into which the other hook portion 20Ac 'is fitted. A groove 10c is formed so as to communicate with the connection hole 10b.

The connecting holes 10a and 10b are
As shown in an enlarged manner in FIG. 6, each axis is formed so as to face the center of the plug 10 with the center of the plug 10 interposed therebetween.

As can be seen from FIGS. 5 and 6, the groove 10c extends clockwise in the figure along the circumferential direction of the outer peripheral surface of the plug 10 from the connection hole 10b, and the depth becomes shallower toward the tip. It is formed so that it becomes.

The connecting portion S 'between the connecting hole 10b and the groove 10c.
In (2), since the inner wall surface of the connection hole 10b is opened to the groove 10c side, the depth of the connection hole 10b is reduced.

When attaching the swing stopper 20 to the stopper 10, the swing stopper 20 is
Of the upper frame 20A
Of the plug 10 is fitted into the connection hole 10a of the plug 10, and then the other hook 20Ac 'is slid forward from the rear of the plug 10 along the groove 10c to form the groove 10c.

When the hook 20Ac 'is fitted into the connecting hole 10b, the hook 20A of the swing stopper 20 is
Since c ′ moves in the direction of the connection hole 10b through the groove 10c whose distance from the connection hole 10a is smaller than the outer peripheral surface of the plug 10, the upper frame 20A is bent and the hooks 20 on both sides are bent.
There is no need to greatly widen the space between Ac and 20Ac ′, so that the swing stopper 20 can be easily attached without requiring much force.

When the bottle container B is discarded, the hook portion 20Ac 'of the upper frame 20A is pulled backward of the plug 10 to release the fitting state with the connection hole 10b, contrary to the above operation. After being slid rearward along the groove 10c and separated from the plug 10, the other hook 2Ac is pulled out from the connection hole 10a, and the swing stopper 20 is removed from the plug 10.

At this time, since the depth of the connecting hole 10b is shallow at the connecting portion S 'between the connecting hole 10b and the groove 10c, the hook portion 20Ac' is extracted from the connecting hole 10b without greatly bending the upper frame 20A. Therefore, the stopper 10 and the swing stopper 20 can be easily separated from each other.

The swing stopper 20 is shown in FIG.
As in the third to third examples, the hook portions 20Bd and 20Bd ′ of the lower frame 20B are fitted into the connection holes B1a and B1b formed on the outer peripheral surface of the bottle opening B ′ of the bottle container B, respectively. To the bottle B. Further, the engagement and disengagement of the hook 20Bd 'with respect to the connection hole B1b is as follows.
This is performed through the groove B1c.
