Description

[Detailed explanation of the idea] This invention relates to liquid containers such as thermos flasks.

The applicant has already developed a plug body for opening and closing the opening of the lower mouth member.
It consists of a stopper body and a stopper screw body that is loosely fitted into the stopper body and screwed onto the lower mouth member, and the stopper body and the stopper screw body rotate relative to each other within a certain angle during liquid injection. We proposed a stopper for liquid containers that is movable.

However, according to this, when injecting liquid by rotating the stopper body at a certain angle from the closed state, the stopper screw body and the stopper body rotate together without relative rotation, and the stopper screw body There is an inconvenience that the formed liquid passage is constantly located at a preset position (for example, the liquid path on the valley line of the four corners of the lower mouth member), making it difficult to pour the liquid content.

This invention has a co-rotation prevention means that prevents the stopper body and the stopper screw body from rotating together when pouring liquid due to the rotation of the stopper body in the opening direction. The above-mentioned disadvantages are solved by providing a liquid container, and one embodiment thereof will be described below with reference to FIGS. 1 to 5 using a liquid container that can be called a square pot as an example.

Reference numeral 1 denotes a container body having a rectangular cross section;
The figure shows an outer case 2, a bottom plate 3 connected to the lower part of the outer case 2, and an upper part fitted into the upper opening of the outer case 2 and fixed at its four corners to the bottom plate 3 with long screws 4,4°4.4. and a lower mouth member 5 having a rectangular shape.

The upper part of the opening 5a of the lower opening member 5 is a dish-shaped wide opening inclined surface,
At the bottom of this wide-mouthed inclined surface, an inner cylinder 5b having a smaller diameter is continuously formed.

An annular inward flange 5c is protruded from the lower part of the inner cylinder 5b, and the upper end of the medium bottle 6 is fitted below the flange 5c via a packing 24, and above the flange 5c. Discontinuous fly screw 1
5 is engraved.

6 is a medium bottle whose upper opening 6a communicates with the opening 5a of the lower mouth member 5; 7 is a member that supports the bottom of the medium bottle 6; and 8 is a stopper with a rectangular upper part that opens and closes the opening 5a of the lower mouth member 5. It is the body.

The plug body 8 can be roughly divided into a plug body 9 that closes the opening 5a of the lower mouth member 5, and a liquid passage 21 that can communicate with the opening 5a of the lower mouth member 5. It consists of a plug screw body 10 that is fitted and screwed onto the lower mouth member 5.

That is, the stopper main body 9 has a rectangular plate-shaped stopper lid 11 on the upper part.
A stepped cylindrical body is provided vertically from the center of the lower surface of the stopper lid 11, and a large diameter shaft portion 9a and a small diameter shaft portion 9b of the stepped cylindrical body.
An annular packing 19 is fitted into the stepped portion of the plug body 9, and by tightly contacting the annular packing 19 with the inward facing flange 5c of the lower opening member 5, the opening 5a of the lower opening member 5 is closed with the plug body 9. be.

In addition, the plug screw body 10 has a fly screw 14 carved on the outer periphery of the lower part, and this screw 14 is screwed into the screw 15 of the lower mouth member 5, and this screw 14 extends in the circumferential direction of the earthen floor. A plurality of liquid passages 21 are bored at intervals, and a flange 16 is formed above the screw 14, and slightly above the flange 16 there is an L formed of horizontal grooves 17a and vertical grooves 17b. It features a letter-shaped guide groove 17.

An inward slider 13 shaped at the lower end of the stopper cover 12 is inserted into the guide groove 17, and the stopper screw body 10 is loosely fitted into the stopper body 9, and the upper part of the stopper screw body 10 and the stopper lid are loosely fitted. A spring 18 is installed between the stopper body 9 and the stopper body 11 to always urge the stopper body 9 upwardly with respect to the stopper screw body 10.

Therefore, the plug screw body 10 of the plug body 8 is attached to the inner cylinder 5b of the lower mouth member 5.
When the screw 14 of the screw body 10 and the screw 15 of the lower mouth member 5 are finally screwed together, when the screw 14 of the screw body 10 and the screw 15 of the lower mouth member 5 are finally screwed together, the lower surface of the flange 16 of the screw body 10 The protrusion 25 shaped like this engages with the anti-rotation protrusion 26 formed on the dish-shaped wide-mouth inclined surface of the lower mouth member 5, so that the stopper screw body 10 is prevented from rotating, and the open screw body 10 is prevented from rotating in the same direction. It cannot be rotated beyond this point.

At this time, the liquid passages 21 of the stopper screw body 10 are provided in advance at positions corresponding to the pouring ports 23 at the four corners of the lower mouth member 5.

When the plug body 9 is further rotated in the same direction, the slider 13 of the plug body 9 is moved down from the vertical groove 17b of the guide groove 17 of the plug screw body 10 to the horizontal groove 17a, and is engaged with the terminal end of the horizontal R17a. At the same time, the opening 5a of the lower mouth member 5 is sealed by the gasket 19 of the stopper body 9, and the content liquid cannot be poured out from the spout 23 of the liquid path 22 (see Fig. 1). ).

Conversely, when the stopper main body 9 is rotated counterclockwise in the closed state shown in the first figure, the slider 13 moves into the vertical groove 17b of the guide groove 17 of the stopper screw body 10 due to the elastic force of the spring 18. is,
The plug body 9 and the plug screw body 10 are rotated relative to each other within a certain angle.

At this time, the liquid passage 21 of the stopper screw body 10 is in communication with the inside of the medium bottle 6, and when the vessel is tilted, the liquid content of the medium bottle is poured out from the spout 23 of the lower mouth member 5.

When pouring the contents into the medium bottle 6, the stopper 8 is removed from the lower mouth member 5.

That is, in the open state (when the slider 13 is engaged in the vertical groove 17b of the guide groove 17), when the stopper main body 9 is further rotated counterclockwise via the stopper lid 11, the stopper screw is screwed. The screw 14 of the body 10 is loosened from the screw 15 of the lower mouth member 5 to be unscrewed, the stopper 8 is removed, and the liquid can be poured into the medium bottle.

The threaded portion of the screw 15 of the lower mouth member 5 and the screw 14 of the stopper screw body 10 is filled with liquid when liquid is poured (opened) by rotating the stopper main body 9 in the opening direction from the closed state shown in the first figure. Co-rotation prevention means 40 that prevents the plug body 9 and the plug screw body 10 from rotating together
is established.

In this embodiment, the co-rotation prevention means 40 includes a retaining protrusion 41 formed below the final screw engagement of the screw 15 of the lower mouth member 5.
and an engagement receiving portion 42 formed at the starting end of the screw 14 of the plug screw body 10, and the engagement receiving portion 42 is formed on the lower opening member 5.
A protrusion 42a formed at the front in the screwing direction of the threaded part of the plug screw body 10 and lower than the thread of the screw of the plug screw body, and a recess 42b formed at the rear thereof are continuously shaped. It's intimidating.

Note that 42c is a screw thread. Therefore, after injecting the content liquid into the inside 'f@6 through the opening 5a of the lower mouth member 5, screw the screw 14 of the stopper screw body 10 and the screw 15 of the lower mouth member 5 clockwise through the stopper lid 11. When screwed together, the sides and corners of the lid 11 and the lower mouth member 5 match to close the lid.

That is, in this closed state, the engagement protrusion 41 of the lower mouth member 5 engages with the protrusion 42a of the engagement receiving part 42 of the closure screw body 10.
At the same time, the protrusion 25 provided below the flange 16 of the plug screw body 10 and the anti-rotation protrusion 26 of the lower mouth part #5 are engaged, ensuring that It is stopped from rotating and cannot be rotated clockwise any further.

Moreover, at this time, the slider 13 of the plug body 9 moves downward against the biasing force of the spring 18 and is engaged in the terminal position of the horizontal groove 17a of the guide groove 17, and the seal 19 of the plug body 9 moves downward against the lower opening member. 5
The upper surface of the flange 5C closes the opening 5a of the lower mouth member 5.

When the stopper body 9 is rotated 45 degrees counterclockwise from the closed state, the engagement protrusion 41 of the lower mouth member 5 remains engaged with the recess 42b of the engagement receiving portion 42 of the stopper screw body 10. Therefore, the plug screw body 10 remains stopped without any rotation.

Therefore, at the same time as the slider 13 moves into the vertical groove 17b, the plug body 9 is moved upward by the elastic force of the spring 18, and the liquid passage 21 of the plug screw body 10 is opened.

In other words, with this configuration, it is possible to reliably open the cap at a certain angle and pour out the liquid content.

When the stopper main body 9 is further rotated counterclockwise from the open state, the slider 13 is engaged in the vertical groove 17b of the stopper main body 9, so that the stopper screw body 10 is connected to the stopper main body 9. The plug body 8 is rotated integrally in the same direction, and finally the plug body 8 can be removed from the lower mouth member 5, and the contents can be taken in and out.

In addition, contrary to the above embodiment, the engagement protrusion 41 may be formed on the plug screw body 10 and the engagement receiving portion 42 may be formed on the lower mouth member 5.

Moreover, the engaging protrusion 41 and the engaging receiving part 42 are not limited to the above-mentioned shape, but can be changed in design as appropriate.

Reference numeral 20 denotes a gasket provided on the outer periphery of the plug body 9, which prevents the liquid from entering the space between the plug body 9 and the plug screw body 10.

Reference numeral 27 denotes an air groove formed on the upper surface of the flange 5C of the inner tube 5b of the lower mouth member 5 in order to prevent negative pressure inside the inner bottle 6 when the bottle is closed. is flowing into the medium bottle 6.

Reference numeral 28 denotes a filamentous rib provided on the valley line of the liquid path section 22 from the upper opening edge of the lower opening member 5 to the spout 23, which guides the content liquid from the opening 5a of the lower opening member 5 and straightens it. It was designed so that it could be poured out.

29 is the protrusion 2 on the inclined surface directly above the detent protrusion 26.
The content liquid whose flow is disturbed by the anti-rotation protrusion 26 is guided to the liquid path 22 at the corner along the lower part of the protrusion 29, so that the content is longer than the protrusion 6. There is an advantage that the liquid is poured out in a rectified manner.

Reference numeral 30 denotes a recess formed in the side wall near the spout 23, which facilitates drainage during pouring.

In addition, in the embodiment, the stopper lid 11 of the stopper body 8 and the lower mouth member 5
Although the upper part has a rectangular shape, it can be formed into other polygonal shapes such as a pentagon, a hexagon, or a generally used circular shape, and the shape is not limited.

Further, the cross section of the outer case 2 is not limited to a quadrangular shape, but may be other polygonal shapes, circular shapes, etc., and the shape is not limited.

According to this invention having the above-mentioned configuration, the plug body 8 is composed of a plug body 9 and a plug screw body 10.
0 is a stopper of a liquid container that can be relatively rotated within a certain angle during liquid injection, and is connected to the lower mouth member 5 and the stopper screw body 10.
The threaded portion is provided with co-rotation prevention means 40 that prevents the cap body 9 and the cap screw body 10 from rotating together when liquid is injected by rotating the cap body 9 in the opening direction. When injecting liquid by rotating the stopper body 9 by a certain angle from the closed state, the stopper screw body 10 and the stopper main body 9 do not rotate together and are accurately rotated relative to each other. The liquid passage 21 formed in the body 10 corresponds reliably to the preset liquid path part 22.

Therefore, the content liquid is poured out from the spout 23 via the liquid path 22, which has the advantage of being easy to pour.
