Embodiment approach 1

[0145] figure 1 It is an example of an external perspective view of the gas-adsorbing device before opening according to Embodiment 1 of the present invention, figure 2 This is an example of an external perspective view of the unsealed gas-adsorbing device of this embodiment.

[0146] Such as figure 1 , figure 2 As shown, the gas-adsorbing device 5a of Embodiment 1 basically includes: a gas-barrier storage container 6a of an elongated flat cylindrical body that seals a gas-adsorbing substance (not shown) under reduced pressure; and an unsealing member 7a around which The axis of the longitudinal direction of the storage container 6a is attached around the storage container 6a, and has the pressing part which presses the storage container 6a. In addition, the opening member 7 a has a shape in which both one surface and the other surface are sandwiched between both ends in the short side direction (width direction) of the storage container 6 a. Then, the flat surface of ...

Embodiment approach 2

[0176] image 3 It is an example of an external perspective view of the gas-adsorbing device before opening in Embodiment 2 of the present invention, Figure 4 This is an example of an external perspective view of the unsealed gas-adsorbing device in this embodiment.

[0177] Such as image 3 As shown, the gas-adsorbing device 5b of the second embodiment has first protrusions 12, second protrusions 13, and third protrusions 14 in the longitudinal direction of the storage container 6a instead of the protrusions 10 of the gas-adsorbing device 5a of the first embodiment. And, if Figure 4 As shown, when a predetermined external force is applied to the movable part 9, that is, close to image 3 When an external force is applied in the direction of the flat surface of the storage container 6a, the first protrusion 12, the second protrusion 13, and the third protrusion 14 penetrate the flat surface of the storage container 6a. That is, the gas-adsorbing device 5b of Embodiment 2...

Embodiment approach 3

[0183] Figure 5 It is an example of an external perspective view of the gas-adsorbing device before opening according to Embodiment 3 of the present invention.

[0184] Such as Figure 5 As shown, the difference between the gas adsorbing device 5c of the third embodiment and the gas adsorbing device 5b of the second embodiment is that the storage container 6b with non-uniform thickness is used, and the storage container 6b has an extremely flat thin container portion 16 and The flat storage container thick portion 17 is thicker than the storage container thin portion. In addition, as in the second embodiment, when a predetermined external force is applied to the movable part 9, that is, when the movable part 9 approaches Figure 5 In the case of an external force in the direction of the flat surface of the storage container 6, the first protrusion 12, the second protrusion 13, and the third protrusion 14 penetrate the flat surface of the storage container 6b to form three t...

Abstract

The invention provides a gas-adsorbing device (5a), which includes gas-adsorption material, a long, narrow, flat cylindrical body housing container (6a) with gas barrier properties wherein the gas-adsorption material has been depressurized and sealed, and an unsealing member (7a), which is attached so as to encircle the housing container around the longitudinal axis of the housing container and is provided with a protrusion (10) that opens a through hole in the housing container. The unsealing member has a holding part (8) that grips the outer surface of the cylindrical body in the direction of the width of the housing container and surrounds the outer surface of the cylindrical body in the direction of the circumference so as to at least cover a part of a surface on the opposite side from a surface in which the through hole is opened where the protrusion that penetrates the housing container may come into contact therewith from the inside of the housing container and a movable part (9) the fixed end of which is provided so as to be connected to the holding part and on the free end of which is formed a protrusion. The constitution is such that when the housing container is gripped in the direction of width by the holding part, the movable part, before unsealing, is opposed thereto at a slope with a prescribed angle, opening a space with the surface on the side in which the through hole is to be opened. When the movable part is pushed with a prescribed force during unsealing in the direction approaching the surface on the side in which the through hole is to be opened, the protrusion pierces the surface on the side in which the through hole is to be opened.

Description

technical field [0001] The present invention relates to a gas adsorption device and a vacuum heat insulating material having the same. Background technique [0002] In recent years, as a countermeasure against global warming, which is a problem of the global environment, energy conservation has been actively promoted. In particular, with regard to warm and cold heat utilization equipment, vacuum heat insulating materials having excellent heat insulating performance are spreading from the viewpoint of effective use of heat. Vacuum heat insulating materials are processed into a bag-shaped laminated film with gas barrier properties, and accommodate a core with a high gas phase volume ratio such as glass wool and a microscopic void. material obtained by sealing the laminated film under reduced pressure. In addition, by making the void diameter of the core material smaller than the mean free path of gas molecules under reduced pressure, the gas heat conduction component of the ...
