  The present invention pays attention to the above-mentioned problems, and as a result of repeatedly conducting various experiments and researches, provides a groundbreaking heat-resistant storage container that has never existed before.

  The gist of the present invention will be described with reference to the accompanying drawings.

  A container body 3 provided with a peripheral wall portion 3a and a bottom wall portion 3b having a vacuum heat insulating structure, and a lid body provided in a fitted state on the container main body 3 and provided with a peripheral wall portion 6a and a bottom wall portion 6b having a vacuum heat insulating structure. 6, the outer peripheral surface of the peripheral wall portion 3 a of the container body 3 and the peripheral wall portion of the lid body 6 when the cover body 6 is disposed in a fitted state with respect to the container main body 3. Between the inner peripheral surface of 6a, the heat-resistant sealing material 10 provided in the surrounding state by the at least one of the peripheral wall part 3a of this container main body 3 and the peripheral wall part 6a of the cover body 6 is interposed. The present invention relates to a heat-resistant container.

  Moreover, the container main body 3 provided with the peripheral wall part 3a and the bottom wall part 3b of the vacuum heat insulating structure, and the lid provided with being fitted in the container main body 3 and provided with the peripheral wall part 6a and the bottom wall part 6b of the vacuum heat insulating structure. A heat-resistant storage container composed of a body 6, and when the lid body 6 is fitted into the container body 3, the inner peripheral surface of the peripheral wall portion 3 a of the container body 3 and the peripheral wall of the lid body 6 Between the outer peripheral surface of the part 6a, a heat-resistant sealing material 10 provided in an enclosed state is interposed in at least one of the peripheral wall part 3a of the container body 3 and the peripheral wall part 6a of the lid body 6. The present invention relates to a heat-resistant container.

  Further, in the heat-resistant storage container according to any one of claims 1 and 2, a heat-resistant seal material 10 that thermally expands is adopted as the heat-resistant seal material 10. It is related.

  Since the present invention is configured as described above, for example, it is possible to suppress the rise in internal temperature as much as possible even when exposed to a high temperature environment. It becomes a storage container.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  An appropriate object is accommodated in the container body 3, and the lid body 6 is arranged in a fitted state on the container body 3.

  Even if the container body 3 and the lid body 4 are both provided with a vacuum heat insulation structure in a vacuum space even if exposed to a high temperature environment due to a fire or the like, they are extremely excellent in heat insulation, An increase in the internal temperature is suppressed as much as possible.

  Therefore, it is very good at storing important documents and valuables.

  Further, according to the present invention, when the lid body 6 is disposed in a fitted state with respect to the container body 3, the space between the outer peripheral surface of the peripheral wall portion 3 a of the container main body 3 and the inner peripheral surface of the peripheral wall portion 6 a of the lid body 6. Since the heat-resistant sealing material 10 provided in an enclosed state is interposed in at least one of the peripheral wall portion 3a of the container body 3 and the peripheral wall portion 6a of the lid body 6, it has excellent heat insulating performance. However, satisfactory opening and closing of the lid 6 is achieved.

  That is, since the product according to the present invention is an article whose ability is to be exhibited in an environment where heat insulation is required, for example, in a high temperature environment, the lid body 6 is fitted to the container body 3. When disposed, in order to prevent heat from entering, the outer peripheral surface of the peripheral wall portion 3a of the container body 3 and the inner peripheral surface of the peripheral wall portion 6a of the lid body 6 are required to be in close contact, In this case, a large resistance is generated due to rubbing when the lid 6 is opened and closed, and smooth opening and closing cannot be performed (inconvenience is deteriorated). In addition, since the dimensions of the container body 3 and the lid body 6 must be manufactured with high accuracy, there is a problem that the mass productivity is low and the cost is high. .

Even if a gap is formed between the outer peripheral surface of the peripheral wall portion 3a and the inner peripheral surface of the peripheral wall portion 6a of the lid body 6, it is possible to provide a structure that reliably prevents the intrusion of heat. Since the container body 3 and the lid body 6 are not required to be so precise, the cost can be reduced and the mass productivity can be improved.

  Further, in the invention described in claim 3, since the heat-resistant sealing material 10 that thermally expands is adopted as the heat-resistant sealing material 10, for example, at normal times (in a normal temperature environment), the heat-insulating sealing material 10 is a lid. The lid 6 can be opened and closed smoothly by keeping it away from the inner peripheral surface of the body 6. On the other hand, in an emergency (for example, in a high temperature environment such as a fire), the lid 6 is thermally expanded. The lid 6 can be surely brought into contact with the inner peripheral surface of the lid body 6 to prevent heat from entering, and the lid body 6 is unexpectedly brought into contact with the heat-resistant sealing material 10 when it falls down. It can also be prevented from coming off.

Sealing means using a copper tip tube 25 may be used. In this tip tube means, the tip tube 25 and the part 26 to be vacuum-sealed are included in order to protect the tip tube 25 and the protective material 26 covered by the tip tube 25 from heat. The point provided on the body is significant (because the tip tube 25 is made of copper, it is thermally expanded and damaged in a high temperature environment). Further, the concealing member 27 is arranged by providing the tip tube 25 in the content body. Reference numeral 17 denotes a bottom material disposed in the lower part of the container body 3.

  Thereafter, the heat-resistant sealing material 10 is disposed in the concave portion 9 provided on the peripheral wall portion (external body 1) of the container body 3.

Adopting the heat-resistant sealing material 10 is extremely innovative.

  That is, the product according to the present embodiment is an article whose ability is to be exerted in an environment where heat insulation is required, for example, in a high temperature environment. In order to prevent heat from entering, the outer peripheral surface of the peripheral wall 3a of the container body 3 and the inner peripheral surface of the peripheral wall 6a of the lid 6 are required to be in close contact with each other. In this case, a large resistance is generated by rubbing when the lid 6 is opened / closed, and smooth opening / closing cannot be performed (inconvenience is deteriorated). There are problems such as the formation of a gap, and furthermore, since the dimensions of the container body 3 and the lid body 6 must be manufactured with high accuracy, there is a problem that the mass productivity is low and the cost is high. is there.

  In this respect, the present embodiment is configured such that the heat-resistant sealing material 10 is disposed between the outer peripheral surface of the peripheral wall portion 3a of the container body 3 and the inner peripheral surface of the peripheral wall portion 6a of the lid body 6. Even if the gap X is formed between the outer peripheral surface 3 and the inner peripheral surface of the lid body 6, it is possible to provide a structure that reliably prevents heat from entering. Providing the concave strips 9 for disposing allows the heat-insulating sealing material 10 to be satisfactorily disposed, and this heat-insulating sealing material 10 under normal conditions (normal temperature environment). Is not in contact with the inner peripheral surface of the peripheral wall portion 6a of the lid body 6 so that the lid body 6 can be opened and closed smoothly (see FIG. 9). On the other hand, in an emergency (for example, a high-temperature environment such as a fire) In (lower), it is possible to prevent thermal intrusion by thermally expanding and reliably contacting the inner peripheral surface of the lid 6. See Figure 10). In addition, the heat insulating sealing material 10 expands by receiving heat, so that it is possible to prevent the lid body 6 from being unexpectedly removed when it falls down.

  In addition, it is good also as a structure which forms the recessed strip part 9 in the internal peripheral surface of the surrounding wall part 6a of the cover body 6 mentioned later, and arrange | positions the heat insulating sealing material 10 in this recessed strip part 9, and the surrounding wall of the container main body 3 is good.

  Further, a locking member 22a constituting a separation preventing means 22 for preventing separation of the lid body 6 to be described later is provided at a position facing the outer peripheral surface at the lower portion of the container body 3.

  This locking member 22a is made of a metal (stainless steel) having an appropriate heat resistance as shown in FIGS. 1 and 2 and formed into a plate shape. The front end locking portion is configured to be able to be locked to a protrusion 22b provided on the lid body 6 to be described later.

  The separation preventing means 22 may be appropriately adopted as long as it has a configuration that exhibits the characteristics of this embodiment, such as a type in which a band made of a heat-resistant material is wound.

  The lid body 6 has substantially the same structure as the container body 3 described above, and includes an outer container body 4 and a content body 5.

  Specifically, as shown in FIG. 2, the outer container 4 is formed by welding a stainless steel bottom wall (bottom plate member) 4b to an upper opening of a stainless steel peripheral wall (tubular member) 4a. It is a bottom cylindrical body. The material of the outer container 4 is not limited to stainless steel, but may be appropriately selected as long as it exhibits the characteristics of this embodiment, such as iron or titanium.

  As shown in FIG. 2, the content body 5 is formed by welding a stainless steel bottom wall (bottom plate member) 5b to an upper opening of a stainless steel peripheral wall (tubular member) 5a in the same manner as the outer container 4 described above. It is the bottomed cylindrical body formed. The material of the content body 5 is not limited to stainless steel, and may be appropriately selected as long as it exhibits the characteristics of this embodiment, such as iron or titanium.

  Further, the content body 5 is formed with a recess 14 at the center position of the bottom wall 5 b, and a through hole 8 is formed at the center position of the recess 14.

  The through hole 8 functions as an exhaust hole 8 when the space between the outer container 4 and the content body 5 is vacuum-sealed.

  When the lid body 6 is manufactured from the external body 4 and the content body 5 having the above-described configuration, the content body 5 is coaxially arranged in the external body body 4 and a predetermined gap is provided between the peripheral walls 4a and 5a and the bottom walls 4b and 5b. Arrange with space in between. Subsequently, both lower openings 4c and 5c are joined together. Subsequently, an appropriate brazing material 15 is placed in the concave portion 14 of the content body 5, and a sealing plate 16 is placed on the brazing material 15. The space between the contents 5 is made the vacuum space S2, and the brazing material 15 is melted by heating, and the exhaust hole 8 is closed with the sealing plate 16 (see FIGS. 3 and 4).

  As the sealing means for the exhaust hole 8, a sealing means for sealing the exhaust hole 8 with a molten brazing material 15 as shown in FIGS. 5 and 6, or as shown in FIGS. Sealing means using a copper tip tube 25 may be used. In this tip tube means, the tip tube 25 and the protective material 26 covered by the tip tube 25 are protected from heat, and the portion to be vacuum-sealed is included. The point provided on the body is significant (because the tip tube 25 is made of copper, it is thermally expanded and damaged in a high temperature environment). Further, the concealing member 27 is arranged by providing the tip tube 25 in the content body. Reference numeral 18 denotes a handle member disposed on the top of the lid body 6.

  In the present embodiment, the height of the peripheral wall 6 a of the lid 6 is substantially the same as that of the peripheral wall 3 a of the container body 3.

  This is because when the lid body 6 is disposed in a fitted state with respect to the container body 3, by increasing as much as possible the overlapping portions of the peripheral wall portions 3a, 6a, the inside and outside of the container body 3 Therefore, it is possible to obtain a state in which heat hardly enters the inside. In the present embodiment, the lid body 6 is disposed in a fitted state with respect to the container body 3, but the lid body 6 may be disposed in the container body 3 in a fitted state.

  Further, the lid body 6 is provided with a projection 22b constituting a separation preventing means 22 for preventing separation from the container body 3 at a position facing the outer peripheral surface at the lower portion.

  As shown in FIGS. 1 and 2, the protrusion 22 b is configured by protruding a metal member (stainless steel) having appropriate heat resistance at a position facing the outer peripheral surface of the lid body 6.

  Reference numeral 19 denotes a disk rack that collects a plurality of disks 20 such as CDs and DVDs.

  Since the present embodiment is configured as described above, an appropriate object (CD, DVD) is accommodated in the container main body 3, and the lid body 6 is disposed in a fitted state on the container main body 3.

  Even if the container body 3 and the lid body 4 are both provided with a vacuum heat insulation structure in a vacuum space even if exposed to a high temperature environment due to a fire or the like, they are extremely excellent in heat insulation, An increase in the internal temperature is suppressed as much as possible.

  Therefore, according to the present embodiment, it is very excellent in storing important documents and valuables.

  In the present embodiment, the container body 3 is vacuum-sealed in the exhaust hole 7 provided in the content body 2, and the lid 6 is also vacuum-sealed in the exhaust hole 8 provided in the content body 5. Since the stop treatment is performed, the heat insulation is further improved.

  That is, when manufacturing the container main body and the lid, it is assumed that an exhaust hole is provided in the outer body that constitutes the container main body and the lid, and a vacuum sealing process is performed in the exhaust hole (conventional manufacturing aspect). In general, an exhaust hole is provided in the outer container and vacuum-sealed, and the outer container is directly exposed to a high-temperature environment, particularly in the case of a cover-fitting structure. There is a risk of heat entering from the exhaust hole provided in the interior.

  Specifically, for example, the vacuum sealing process is generally performed using a sealing plate and a brazing material, but in an environment (for example, fire) higher than the melting temperature of the brazing material. In this case, if a structure for exhausting air from an exhaust hole provided in the outer container is adopted, the vacuum-sealed portion is directly exposed to high-temperature heat and the brazing material is melted (a general brazing material). The melting temperature is 900 ° C. to 1050 ° C., and the high temperature environment due to the fire is 1000 ° C. to 1200 ° C.), and heat may enter the inside from this vacuum sealed part (exhaust hole). is there.

  In this regard, if a structure for vacuum sealing treatment is adopted in the exhaust hole provided in the content body, this vacuum sealed part does not reach the melting temperature of the brazing material, so this vacuum sealed part (exhaust hole) Therefore, heat does not enter from the inside, so that the heat insulating performance is surely exhibited.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
