Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a heat-retaining pot in which an inner bottle made of a vacuum double glass bottle is placed inside an outer case, in order to prevent the inner bottle from being damaged. .

[Conventional technology]

In conventional heat-retaining pots using medium glass bottles, the opening of the medium bottle is fitted and fixed to a spout member fixed to the outer case via a spout seal, and the bottom of the medium bottle is screwed to the outer case. The medium bottle was held in the outer case by being received by the elastic bowl-shaped part of the tightening tool.

[The problem that the idea aims to solve]

However, in this case, if a strong impact is applied in the lateral direction, the opening of the inner bottle, which is fitted and fixed, or the vicinity thereof, is likely to be damaged by the impact, and the inner bottle may come off from the tightening tool and collide with the outer case. There were also cases of damage. Therefore, it was not possible to carry the heat-retaining pot on excursions, mountain climbing, etc., and its range of uses was limited. On the other hand, in recent years, a vacuum double container made of stainless steel and equipped with a medium bottle has been commercially available, but it is quite expensive.

In view of these problems, the present invention aims to provide an inexpensive heat-retaining pot using a glass inner bottle that prevents the inner bottle from being damaged.

[Means to solve the problem]

In order to achieve the above object, the heat-retaining pot of the present invention has a heat-retaining pot in which an inner bottle 20 made of a vacuum double glass bottle is placed inside an outer case 1, as shown in the drawings corresponding to the embodiments. A large number of independent air chambers 11, 11 are formed by flexible sheet-like bodies 9, 10 between the inner periphery of the bottle 1 and the outer periphery of the medium bottle 20.
... 11 and a ventilation passage 12 that communicates and connects these air chambers 11, 11...11, and supports the medium bottle 20 so as to be displaceable in a direction perpendicular to the axis. It is what it is.

The shock absorber 8 includes a flexible sheet-like body 9 formed into a planar shape, and a plurality of recesses formed in the vertical and horizontal directions, and narrow grooves that communicate between the opening edges of adjacent recesses. Flexible sheet-like body 10
It is formed by overlapping and bonding together by ultrasonic bonding etc., and the flexible sheet-like body 9 formed in the planar shape connects the other flexible sheet-like body to the other flexible sheet-like body. The opening ends of all 10 recesses are sealed to form air chambers 11, and the narrow grooves that communicate adjacent air chambers 11 are formed as ventilation passages 12.

[Effect]

When the shock absorber 8 receives a shock, the air in the air chambers 11, 11, . The air is press-fitted into the air chambers 11, and acts to absorb shock through the air compression and movement resistance between them.Furthermore, after the shock is absorbed, due to the increase in pressure within the air chambers 11, 11...11 into which the air has flowed,
The original air chamber 11, 11 where the air was impacted
. . 11 to quickly return the medium bottle 20 to its original holding position, it is possible to reliably absorb and alleviate the impact and maintain the position of the medium bottle 20 after the shock has been absorbed.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIG. 1, 1 is an outer case,
An outer lid screw portion 4 is formed at the upper end via a step portion 3 with which the end surface of the outer lid 2 comes into contact, and a shoulder portion 5 extends radially inward from the upper end. Also, outer case 1
A mounting screw 7 for screwing the bottom cover 6 is formed on the inner periphery of the lower end. An air cushion type shock absorber 8 is attached to the inner periphery of the outer case 1 by adhesive or the like.

As shown in FIG. 2, this shock absorber 8 has a flexible sheet-like body 9 formed into a planar shape, and a large number of recesses in the vertical and horizontal directions, and the opening edges of adjacent recesses communicate with each other. It is formed by superposing the flexible sheet-like body 10 formed with narrow grooves with the concave portions on the inside and ultrasonically bonding them to each other. The open ends of all the recesses of the other flexible sheet member 10 are sealed by the sheet member 9, and the recesses are closed to the air chamber 1.
1 and the above-mentioned narrow grooves that communicate with the adjacent air chambers 11 are formed in the ventilation passages 12.

A spout member 13 is disposed penetrating the inner periphery of the shoulder portion 5 of the outer case 1 with a gap therebetween so as to be displaceable in the radial direction, and the spout member 13 extends radially outward from the inner end of the outer case 1. An annular plate part 14 extends downward from the outer peripheral edge thereof, and a threaded part 15 for connecting the inner case extends downward from the inner periphery of the shoulder part 5. annular protrusion 5
It is engaged with a. A spout gasket 17 is fitted into a stepped portion 16 formed on the lower inner periphery of the spout member 13, and an inner stopper 19 is fitted onto a screw 18 formed on the upper inner periphery.
are fitted.

The mouth gasket 17 has a medium bottle 20 made of a vacuum double glass bottle housed and held in an inner case 21.
The opening 20a of the spout member 1 is abutted and fitted, and the threaded portion 22 on the outer periphery of the upper end of the inner case 21 is connected to the spout member 1.
By screwing into the threaded portion 15 of No. 3, the spout member 13, the inner bottle 20, and the inner case 21 are integrally connected.

23 is an annular elastic body interposed between the annular protrusion 5a on the inner periphery of the shoulder portion 5 and the lower outer periphery of the spout member 13, and 23 is an annular elastic body that is inserted between the annular protrusion 5a on the inner periphery of the shoulder portion 5 and the lower outer periphery of the spout member 13, and is inserted into the outer case 1 while allowing displacement of the spout member 13 in the radial direction. It is made of a tubular body made of an elastic material such as rubber or synthetic resin, or a solid body with an appropriate cross-section.

Reference numeral 24 denotes a spring interposed between the lower outer surface of the inner case 21 and the inner surface of the bottom cover 6, which strongly pushes up the inner case 21 and pushes the annular plate portion 14 of the spout member 13 against the shoulder portion 5 of the outer case 1. This is to engage the object.

25 and 26 are the inner case 21 and the bottom cover 6, respectively.
This is a positioning protrusion for the spring 24 provided in a protruding manner.

In the above configuration, when assembling, the shock absorber 8 is attached to the inner periphery of the outer case 1, and the spout member 1
3. Mouth packing 17, middle bottle 20 and inner case 2
This assembly is inserted from the lower end of the outer case 1, the annular plate part 14 of the spout member 13 is engaged with the shoulder part 5, and the spring 24 is inserted between it and the lower end of the inner case 21. The assembly is completed by screwing the bottom cover 6 onto the lower end of the outer case 1, arranging the annular elastic body 23 as appropriate, and attaching the inner plug 19 and the outer cover 2.

In this assembled state, if the pot receives an impact in the axial direction, that is, in the height direction,
The medium bottle 20 is elastically supported between the inner case 21 and the spout packing 17, and the spout member 13 and the medium bottle 2
Since the entire assembly of the inner case 21 and the inner case 21 is elastically supported by the spring 24, it is sufficiently cushioned and will not be damaged. Further, even if the inner case 21 is not provided, the opening gasket 17 and the spring 24 provide elastic support and the device will not be damaged.

On the other hand, when a shock is received in the radial direction, that is, in the lateral direction, the spout member 13, the inner bottle 20, and the inner case 21 resist the axial center holding force of the assembly spring 24 and the elastic support force of the annular elastic body 23. The impact is absorbed by the impact absorber 8, and no damage occurs. That is, in this case, the air in the air chambers 11, 11, . ... 11, and acts to absorb shock through the air compression and movement resistance between them.Furthermore, after the shock has been absorbed, the pressure rises in the air chambers 11, 11... Original air chamber 1 in the area that received the impact
1, 11...11 and the spout member 1
3. Since the assembly of the inner bottle 20 and the inner case 21 is quickly returned to its original holding position, shock absorption and relaxation and the position of the assembly after shock absorption can be reliably carried out.

In addition, conventionally, the medium bottle 20, where the impact force was easily concentrated,
Since the opening 20a is also movable together with the spout member 13, impact force will not be concentrated on this portion, and no damage will occur from this portion. Moreover, even when the inner case 21 is not provided, the inner bottle 20 is supported so that it can be displaced, and when the inner bottle 20 is changed, the shock absorber 8
If it is held in place, it will also be buffered and will not be damaged.

[Effect of idea]

According to the heat-retaining pot of the present invention, as is clear from the above description, the inner bottle 20 is supported so as to be displaceable in the lateral direction, that is, in the direction orthogonal to the axis, and
Between the inner periphery of the outer case 1 and the outer periphery of the inner bottle 20, a flexible sheet-like body 9 is formed in a planar shape, and a large number of recesses are formed vertically and horizontally, and the opening edges of adjacent recesses are communicated with each other. A large number of air chambers 11, 11, .
Ventilation passage 1 formed by the narrow grooves that communicate with each other
Since the shock absorber 8 having 2 is disposed,
When the impact occurs, the air chambers 11, 11 in that area
...The air in 11 is compressed and the ventilation passage 12
Air chamber 1 on the circumferential side and the vertical side through
The air chambers 1, 11...11 are press-fitted into the air chambers 11, 11...11, and shock is absorbed extremely well by the air compression and movement resistance between them.Furthermore, after the shock absorption, the air chambers 11, 11... Since the internal pressure has increased, the air flows back into the original air chambers 11, 11, . It is possible. Therefore, shock absorption and relaxation,
The position of the medium bottle 20 after absorbing the shock can be reliably maintained.

Further, since only the shock absorber 8 is interposed between the inner bottle 20 and the outer case 1, and therefore almost only an air layer exists, the heat retention function of the inner bottle 20 is effectively supplemented.
