Definitions

  • the present invention relates to a heat resistant adiabatic bag for protecting valuables from accidents and disasters such as a fire and more particularly to a heat resistant adiabatic bag suitable for protecting valuables stored therein when stored within a safe.
  • a fireproof bag made of a laminated sheet composed of a plurality of layers having excellent fireproofing and heat resistant properties such as a sheet member used for a fireman's cloth and such fireproof bag is used in the site of emergency medical treatment for example. Because such fireproof bag is made so as to be able to sustain partial heat such as sparks and flames and has a good and adequate heat retaining property, it is useful in keeping the quality of medicines and the like stored therein even when used in the open in winter season or in a cold district. Such fireproof bag is arranged so as to be able to open by a fastener or the like so that the contents such as medical equipments and medicines can be readily taken out.
  • the adiabatic bag had an adequate internal heat insulating property, it was undeniable that the internal temperature drops gradually along the decrease of the ambient temperature when the adiabatic bag is used in the outdoors in winter season or in a cold district. As a result, there might be a case when the contents are damaged or decomposed due to the drop of the internal temperature of the adiabatic bag when the contents are substances which are weak to low temperature such as a microfilm or chemicals whose quality change under the low temperature.
  • the present invention has been devised in view of such circumstances and its object is to provide a heat resistant adiabatic bag which has an excellent adiabatic property against an increase of ambient temperature around the adiabatic bag, which is useful and which has an excellent temperature insulating property even against a drop of ambient temperature around the adiabatic bag.
  • a heat resistant adiabatic bag described in Claim 1 comprises an outer bag made of a laminated sheet which has heat resistant and adiabatic properties and which shuts off aeration and an inner bag made of a laminated sheet which has heat resistant and adiabatic properties and which shuts off aeration.
  • the inner bag can be inserted to the outer bag almost without any gap and a sealing sheet made of low fusion point resin is provided corresponding to outside air permeating points of at least the inner bag or the outer bag.
  • the outer bag is made of the laminated sheet having the heat resistant and adiabatic properties and which shuts off aeration and the inner bag inserted therein is made of the laminated sheet having the heat resistant and adiabatic properties and which shuts off aeration, permeation of heat from the surface to the outer bag and to the inner bag may be suppressed effectively.
  • the sealing sheet made of the low fusion point resin is provided corresponding to the outside air permeating points of at least the outer bag or the inner bag, the sealing sheet melts when the ambient temperature around the sealing sheet exceeds the melting point of the low fusion point resin, thus filling up the outside air permeating points. Therefore, it becomes possible to suppress the high temperature air from permeating to the inside of the outer bag or the inner bag from the outside air permeating points or due to thermal conduction via air within the outside air permeating point.
  • the adiabatic bag having the good touch can be realized because a flexible fabric or non-woven fabric may be used as the sealing sheet as far as it melts when the ambient temperature surrounding the adiabatic bag increases.
  • the heat resistant adiabatic bag described in Claim 2 is what the sealing sheet made of the low fusion point resin is laminated in a body with the laminated sheet of at least the outer bag or the inner bag.
  • the heat resistance of the sealing sheet of the adiabatic bag is enhanced by effectively shutting off the facial aeration of the adiabatic bag further and the attachment of the sealing sheet may be improved by laminating the sealing sheet in a body with the laminated sheet.
  • the heat resistant adiabatic bag described in Claim 3 is what the sealing sheet is provided along the seam of at least the outer bag or the inner bag. Although the adiabatic property normally drops because heat permeates from seam holes, the sealing sheet melts and fills up the seam holes when heat tries to permeate from the seam holes, so that the air-tightness of the outer bag and the inner bag may be enhanced and the permeation of heat into the adiabatic bag may be prevented effectively.
  • the heat resistant adiabatic bag described in Claim 4 is what the sealing sheet is provided at the overlap portion of the flaps for opening/closing the opening of at least the outer bag or the inner bag. Normally, the gaps of the overlap portion of the flaps tend to become the outside air permeating point and heat permeates from this part. However, when the sealing sheet is provided as described above, the sealing sheet melts and fills up the gap at the overlap portion of the flaps, so that the air-tightness of the outer bag and the inner bag may be enhanced, thus effectively preventing heat from permeating into the adiabatic bag.
  • the heat resistant adiabatic bag described in Claim 5 is what the opening of the outer bag is created so as to be openable by a fastener made of heat resistant synthetic resin having small thermal conductivity; a cover section for covering the fastener from the outside is created at the part facing to the opening of the outer bag; and the sealing sheet is provided along the part facing to the fastener of the cover section.
  • the use of the fastener made of the heat resistant synthetic resin having the small thermal conductivity allows the increase of the temperature within the outer bag to be suppressed by suppressing thermal conduction via the fastener and the sealing sheet provided along the part of the cover section facing to the fastener melts and fills up the small gap, thus preventing heat from permeating to the inside of the outer bag.
  • the heat resistant adiabatic bag described in Claim 6 is what any one of polyimide resin, polyorephine resin or polyesther resin is used as the sealing sheet made of the low fusion point resin.
  • thermosetting resin used as the raw material, the permeation of heat into the adiabacic bag may be suppressed effectively because the melting point of the sealing sheet is 80 to 90°C and the sealing sheet melts and fills up the outside air permeating points when the ambient temperature surrounding the adiabatic bag exceeds 100°C due to a fire or the like.
  • the heat resistant adiabatic bag described in Claim 7 is what is provided with a box-like storage case which can be inserted to the inner bag and in which a shock absorber is attached on the inner face. Because the shock absorber is attached on the inner surface of the storage case, the contents within the storage case may be favorably protected from a shock. Further, because the shock absorber is attached within the box-like storage case, the shock absorber may be assembled readily as compared to the case of attaching the shock absorber to the inner bag made of the soft laminated sheet.
  • the heat resistant adiabatic bag described in Claim 8 comprises a flat main body whose upper face may be opened in the horizontal position and a lid for opening/closing the upper face of the storage case.
  • the heat resistant adiabatic bag described in Claim 9 is provided with heating means which is actuated when internal temperature of the inner bag or the storage case drops below a certain temperature.
  • heating means which is actuated when internal temperature of the inner bag or the storage case drops below a certain temperature.
  • the heat resistant adiabatic bag described in Claim 10 is what the inner bag is inserted to the outer bag almost without any gap while directing the opening side of the inner bag to the back side of the outer bag.
  • the increase of temperature within the inner bag caused by heat permeating from the opening is suppressed further because the heat transmission path reaching to the opening of the inner bag is extended. Still more, because the increase of temperature within the inner bag is suppressed further because the inner bag is inserted to the outer bag almost without any gap therebetween and a passage area of the heat transmission path becomes small.
  • the heat resistant adiabatic bag described in Claim 11 is what the flap for opening/closing the opening of the inner bag is provided in the inner bag and the flap can be closed by a heat resistant face fastener. Accordingly, heat may be suppressed from permeating from the opening of the inner bag while fully maintaining the operability of the opening of the inner bag.
  • the heat resistant adiabatic bag described in Claim 12 is what a magnetic proofing shield is built in the laminated sheet of the outer bag. Accordingly, it becomes possible to prevent the contents stored in a magnetic recording medium such as a floppy disk from being extinguished carelessly when it is stored within the adiabatic bag.
  • a heat resistant adiabatic bag 1 of the present invention comprises an outer bag A, an inner bag B inserted to the outer bag A almost without any gap and a storage case C inserted to the inner bag B. While storing valuables in the storage case C, the storage case C is inserted to the inner bag B and the inner bag B is inserted to the outer bag A while directing its opening 30 side to the back side of the outer bag A. Accordingly, the valuables are protected from a fire and the like by the triple structure of the both bags A and B and the storage case C. It is noted that although it is preferable to use the adiabatic bag 1 by putting it into a fireproof safe as described later from the aspect of fully exhibiting its performance, it may be also used solely.
  • the outer bag A will be explained below at first.
  • the outer bag A is made of a sealing sheet which has heat resistant and adiabatic properties and which shuts off aeration. It has an opening 10 created at its front and is provided with side flaps 12 which extend forward and which are made in a body respectively with side sheets 11 at the right and left of the opening 10 and an inner flap 14 which extends forward at a lower sheet 13 in a body with it.
  • a belt-like opening/closing flap 15 is attached near the front edge of the right side sheet 11.
  • the opening/closing flap 15 is connected with the front edge of an upper sheet 17 and with the front edge of the lower sheet 13, respectively, through an intermediary of two streaks of fasteners 16 so as to be able to close the opening 10 of the outer bag A.
  • the two streaks of fasteners 16 are provided inside from the upper and lower edge of the opening/closing flap 15 by a certain distance and cover sections 18 which cover the fasteners 16 from the outside by the upper and lower edges of the opening/closing flap 15 are created.
  • fasteners 16 by synthetic resin having a heat resistance to at least around 200°C and small thermal conductivity such as phenol resin, melamine resin, epoxy resin, fluororesin, and polyimide.
  • FIG. 5 it is also possible to provide only one streak of fastener 23 for opening/closing the opening 10 of the outer bag A so as to be able to close the opening/closing flap 15 by two streaks of face fasteners 24 provided along the fastener 23 and to cover the fastener 23 by the opening/closing flap 15 in order to simplify the opening/closing operation of the outer bag A.
  • the opening/closing flap 15 is made so that an idle edge portion thereof can be adhered to and fixed near the front edge of the left side sheet 11 via a face fastener 19.
  • Sealing sheets F made of low fusion point resin are provided at the regions hatched in the figure in the overlap portions of the flaps 12, 14 and 15.
  • the sealing sheet F made of low fusion point resin is a woven cloth or non-woven cloth using fibrous low fusion point resin. Thickness of the sealing sheet F is set to be the optimum thickness corresponding to the location where it is provided and it is made to have a thickness which is enough for filling a gap at the overlap portion when it melts when it is provided at the overlap portion of the flaps 12, 14 and 15 for example.
  • polyimide resin, polyolephine resin and polyesther resin may be used solely or in combination as the fibrous low fusion point resin used as the raw material. Further, not only the fibrous low fusion point resin, but also thin film low fusion point resin may be used.
  • the above-mentioned sealing sheet F is provided along the part facing to the fasteners 16 of the cover section 18 for covering the fasteners 16 provided at the opening 10 of the outer bag A from the outside. It is also possible to provide the sealing sheet F at the points where outside air permeates other than the parts illustrated above.
  • the laminated sheet S making the outer bag A four-layered sealing sheet composed of a surface layer 21, a first intermediate layer 22, a second intermediate layer 23 and an internal layer 24 is used. It is also possible to make a sheet made of a plurality of layers other than the four-layered structure.
  • the surface layer 21 is made of a fabric made of organic or inorganic fiber excellent in heat resistant and fire-proofing properties to which an aluminum coating is applied, an aluminum foil is laminated, aluminum is evaporated or heat resistant resin is coated on the outside.
  • Alamide fiber or phenol resin may be used as the organic fiber and ceramic fiber, carbon fiber, silicon carbide fiber, asbestos fiber, glass fiber or rock fiber may be used as the inorganic fiber.
  • Silicon resin may be used as the heat resistant resin to be coated. The heat resistance may be enhanced further by coating aluminum or laminating the aluminum foil because reflectivity of radiant heat increases.
  • the first intermediate layer 22 is made of the sealing sheet F whose raw material is the low fusion point resin. Since the sealing sheet F making the first intermediate layer 22 is laminated across the whole laminated sheet S in a body, its property of shutting off the facial aeration of the laminated sheet S is enhanced further during a fire, thus preventing the permeance of heat from the surface of the laminated sheet S as well as from a seam holes 25 more effectively. Since the sealing sheet F is attached in a body with the laminated sheet S as the first intermediate layer 22, it may be attached readily as compared to the case of attaching the sealing sheet F to the outer bag A separately.
  • the sealing sheet F may be provided around a margin to seam 26 of the laminated sheet S cut for the outer bag A as seen in FIG. 7. This location is where the seam holes 25 are created in seaming the outer bag A, i.e. the location from which the outside air permeates. This case is preferable because an amount of sealing sheet F used is small. Further, the sealing sheet F may be provided along the seam holes 25 in seaming the outer bag A without providing it as the first intermediate layer 22 or may be pasted on the surface layer of the margin 26. It is preferable because the location where the sealing sheet F is provided may be readily defined.
  • the second intermediate layer 23 is made of a felt or a fabric made of organic or inorganic fiber excellent in heat resistant and fire-proofing properties.
  • Alamide fiber or phenol fiber may be used as the organic fiber and ceramic fiber, carbon fiber and the like may be used as the inorganic fiber.
  • the felt or the fabric may be coated by a polyimide film excellent in heat resistant and flame-proof properties. Or, it may be coated by the polyimide film hermetically to fill inert gas such as nitrogen gas therein.
  • a magnetic material such as alnico, ferrite, nickel and the like or a sheet member containing carbon may be interposed between the surface layer 21 and the internal layer 24 as a magnetic-proofing shield in consideration of storing a magnetic recording medium such as a floppy disk. It is noted that the first intermediate layer 22 and the second intermediate layer 23 may be arranged in the opposite way.
  • the internal layer 24 is a fabric or knit made of glass fiber, carbon fiber, alamide fiber, phenol fiber or the like which is coated by a resin coating such as silicon resin.
  • the internal layer 24 may be formed to have a laminated structure of fabric or knit of the same component or different components.
  • a shoulder strap or a hand strap so that the adiabatic bag 1 can be carried out right away in emergency.
  • the inner bag B is made of a laminated sheet T which has a heat resistance and which shuts off aeration. It is provided with an opening 30 formed at its front, side flaps 32 which extend forward and are formed in a body with right and left side sheets 31, respectively, and an opening/closing flap 34 which extends forward and which is formed in a body with a lower sheet 33.
  • An idle end portion of the opening/closing flap 34 is arranged so as to be able to be adhered and fixed near the front edge of the upper sheet 36 via a face fastener 35 and the right and left side flaps 32 are arranged so as to be adhered and fixed at the middle portion of the opening/closing flap 34 via a face fastener 37. It is preferable to use fasteners made of a heat resistant material whose thermal conductivity is small as the face fasteners 35 and 37.
  • a laminated sheet T of three-layered structure of a surface layer 41, an intermediate layer 42 and an inner facial layer 43 is used as shown in FIG. 10.
  • the surface layer 41 and the internal layer 43 are made of a fabric or knit woven from glass fiber, carbon fiber, alamide fiber, phenol fiber or the like to which resin coating such as silicon resin is applied.
  • the intermediate layer 42 is made of a felt or fabric woven from heat resistant and fire-proofing organic/inorganic fiber.
  • the intermediate layer 42 is also possible to provide a fabric or knit woven from glass fiber to which silicon coating is applied at the inner side of the intermediate layer.
  • laminated sealing members made of electrostatic shielding urethane foam may be provided to prevent the devices from being destroyed by static electricity.
  • the insertion direction may be indicated by an arrow on the upper face of the inner bag B for example in order not to insert the inner bag B to the outer bag A in the opposite way.
  • the present invention is very preferable because the heat resistance of the adiabatic bag 1 may be enhanced by the very simple arrangement that the sealing sheet F made of the low fusion point resin is laminated in a body with the laminated sheet S or the laminated sheets S and T.
  • the storage case C allows the valuables stored in the adiabatic bag 1 to be confirmed or taken in and out readily. However, because the outer bag A and the inner bag B can maintain the enough adiabatic property, the storage case C may be omitted.
  • the storage case C is a flat box-like case made of a thick paper or synthetic resin by which aeration is shut off and comprises a main body 50 and a lid 51.
  • the lid 51 is openably linked to one side of the main body 50 through an intermediary of a connecting section 52.
  • the connecting section 52 is connected to one side of a bottom plate 53 of the main body 50 and side walls 54 are provided at the remaining three side.
  • Frame walls 56 are provided at the remaining three walls of the lid 51 except of the side of the connecting section 52.
  • the frame walls 56 are formed so as to overlap with the above-mentioned side walls 55 when the lid 51 is closed as shown in FIG. 2.
  • the frame walls 56 and the side walls 54 are provided with hook members for hooking the lid 51 when the lid 51 is closed.
  • a shock absorbing function may be added to the adiabatic bag 1 by providing a heat resistant shock absorber 60 within the storage case C. Because the storage case C is created as described above and is provided with a wide opening, the shock absorber 60 may be readily attached therein and the manufacturing process may be preferably simplified.
  • shock absorber 60 It is preferable to use a heat resistant closed cell type member such as Suntec Foam (manufactured by Asahi Chemical Industry Co., Ltd.) as the shock absorber 60.
  • a heat resistant closed cell type member such as Suntec Foam (manufactured by Asahi Chemical Industry Co., Ltd.) as the shock absorber 60.
  • the fireproof safe receives a large shock as the fireproof safe drops when the floor gives way or columns and beams hit the fireproof safe during a fire, it becomes possible to protect the valuables from various shocks by providing the shock absorber 60.
  • a case whose lid can be separated completely from the main body 50 as shown in FIG. 13a or a case whose main body is connected directly with a lid 51 without the connecting section 52 as shown in FIG. 13b may be adopted as the storage case C.
  • the shock absorber 60 may be readily provided because the opening of the inner bag B is widened in such a structure.
  • the adiabatic bag 1 comprising the outer bag A, the inner bag B and the storage case C thus structured is very useful in keeping valuables as described below.
  • the storage case C At first, valuables such as money, jewelry, important documents such as securities, recording media such as floppy disks in which important data is recorded are stored in the storage case C. Next, this storage case C is inserted to the inner bag B and the inner bag B is inserted to the outer bag A.
  • the adiabatic bag 1 which is structured as described above and in which the valuables are stored is kept within a fireproof safe.
  • the fireproof safe When the fireproof safe encounters a fire, it is heated up by flames to high temperature and the internal ambient temperature also increases rapidly up to about 100°C. That is, the ambient temperature around the adiabatic bag 1 also increases rapidly up to about 100°C. Then, although high temperature air and heat try to permeate into the adiabatic bag 1, the heat is prevented from permeating from the surface of the laminated sheet S because the outer bag A composing the adiabatic bag 1 is formed by the laminated sheet S which has the heat resistant and adiabatic properties and which shuts off aeration as described above.
  • the sealing sheet F at the outside air permeating point melts by this heat and fills up the point, so that the outer bag A is put into the air-tight state, thus preventing the heat from permeating from that point. Thereby, it becomes possible to prevent the heat from permeating to the inside of the outer bag A more effectively.
  • the heat cannot but permeate only from the outside air permeating point of the inner bag B similarly to the case of the outer bag A if it tries to permeate into the inner bag B.
  • the sealing sheet F made of the low fusion point resin is laminated in a body around the outside air permeating point of the inner bag B, similarly to the outer bag A, the inner bag B is put into the air-tight state similarly to the outer bag A and no heat permeates into the inner bag B. Therefore, because no heat permeates into the storage case C, the valuables stored in the adiabatic bag 1 may be protected from the heat.
  • the heat resistant and adiabatic effects of the laminated sheets S and T are effective, so that the temperature within the adiabatic bag 1 may be suppressed from increasing. Therefore, the valuables stored in the adiabatic bag 1 may be kept without being exposed to the high temperature and heat.
  • the heat resistant adiabatic bag 1 of the present invention has been explained by exemplifying mainly the case of fire, the adiabatic bag 1 is also effective in using for a certain period of time in the outdoor in a cold district in winter season because the internal temperature is hardly influenced by the outside ambient temperature.
  • the adiabatic bag 1 is also effective in using for a certain period of time in the outdoor in a cold district in winter season because the internal temperature is hardly influenced by the outside ambient temperature.

  • a heater 70 having a simple structure may be provided as a heating means in the adiabatic bag 1 of the present invention.
  • the heater 70 comprises a film heater 71 built in the storage case C, a power source 72 of the film heater 71 and a switch 73 of the power source 72 of the film heater 71.
  • the power source 72 is built in the storage case C, it is desirable to use a dry cell or a button type battery which need only a small space.
  • the power switch 73 may be arranged such that a user operates it or it is actuated automatically when the ambient temperature within the storage case C drops below a certain temperature by using a thermostat.
  • the heater 70 may be provided also within the inner bag B.
  • the internal temperature of the adiabatic bag 1 is always kept within a certain range by adopting such structure, valuables which are sensitive to changes of temperature may be suitably kept.
  • the adiabatic bag used in this performance test was a bag in which the storage case C and the sealing sheet F in the adiabatic bag 1 described above were omitted, the inner bag B was inserted to the outer bag A by directing the opening 30 side toward the back side of the outer bag A and the opening 10 of the outer bag A is opened/closed by using a fastener 16 made of a material whose thermal conductivity is small.

  • the laminated sheet composing the inner bag B As the laminated sheet composing the inner bag B, a laminate whose surface layer 41 and the inner facial layer 43 are a fabric made of alamide fiber to which silicon coating had been applied and the intermediate layer is made of a felt made of ceramic fiber whose thickness from the outer face is 6 mm and electrostatic urethane foam was used.
  • the adiabatic bag was put into the fireproof safe and the fireproof safe was set within a heating furnace.
  • the temperature within the furnace was increased along a standard temperature curve in conformity with the JIS Standard S1037 to set that the temperature within the fireproof safe increases gradually up to 180°C.
  • the temperature within the fireproof safe and the temperature within the inner bag B were measured by every 30 minutes until the temperature within the fireproof safe reaches to 180°C. Then, the result shown in Table 1 was obtained.
  • a diagram shown in FIG. 14 was prepared by using the data shown in Table 1.
  • the rate of increase of temperature within the inner bag B is slower than the rate of increase of temperature within the safe and within the outer bag A and that it is kept in low temperature of less than 60°C for about 100 minutes from the beginning of heating. That is, because accessories such as peal and opal and recording media such as a floppy disk tend to be deformed or affected when the temperature exceeds 60°C, they may be protected from being deformed or affected by heat for a long period of time by storing those valuables within the adiabatic bag and the safe by more than three time as compared to the case when they are just put into the safe.
  • the adiabatic bag 1 is considered to be able to realize excellent characteristics than the adiabatic bag whose performance had been tested because the sealing sheet F melts when the ambient temperature reaches around 80 to 90°C and fills up small gaps in the fastener 16 and the seaming holes 25.
  • the heat resistance and adiabatic property against the increase of ambient temperature around the adiabatic bag may be improved considerably by the simple structure of making the outer bag by the laminated sheet which has the heat resistant and adiabatic properties and which shuts off aeration, of making the inner bag by the laminated sheet which has the adiabatic property and which shuts off aeration and of inserting the inner bag to the outer bag almost without any gap therebetween. Therefore, when this adiabatic bag is stored within a safe, the time during which valuables in the inner bag can be protected is prolonged considerably as compared to the case of storing the valuables just in the safe. Accordingly, it becomes possible to prevent the valuables stored in the inner bag from being burned or lost or from being deformed or affected by heat for a long period of time by using the existing safe.
  • the contents stored in the inner bag may be protected from heat by preventing it from permeating to the outer bag or the inner bag by using the sealing sheet made of the low fusion point resin which melts when it touches high temperature air and which fills up all the outside air permeating points.

  • the heat resistance of the sealing sheet of the adiabatic bag is enhanced and the contents within the adiabatic bag may be protected from high temperature air or heat for a long period of time because the sealing sheet made of the low fusion point resin is laminated in a body with the laminated sheet of at least the outer bag or the inner bag. Further, because the sealing sheet may be attached readily in a body with the laminated sheet and the facial aeration of the adiabatic bag may be readily shut off, the air-tightness of the adiabatic bag may be enhanced.
  • the sealing sheet is provided along the seam of at least the outer bag or the inner bag, so that the sealing sheet fills up holes of the seam even when heat tries to permeate from the holes of the seam and the air-tightness of the outer bag may be enhanced effectively by the small amount of the sealing sheet. It then allows the production cost of the adiabatic bag to be decreased.
  • the sealing sheet is provided at the overlap portion of the flaps for opening/closing the opening of at least the outer bag or the inner bag, so that the sealing sheet provided at the gap of the overlap portion of the flaps fills up this part even when heat tries to permeate therefrom and the air-tightness of the outer bag may be enhanced effectively again by the small amount of the sealing sheet.

Accordingly, it is very suitable in protecting the contents.
  • the air-tightness of the adiabatic bag may be enhanced effectively even when the adiabatic bag is exposed to high temperature air or heat due to a fire or the like because the sealing sheet made of the low fusion point resin used in the inventive heat resistant adiabatic bag melts around 80 to 90°C when any one of polyimide resin, polyorephine resin or polyesther resin described in Claim 6 is used.
  • the adiabatic bag which can sustain a shock may be realized by storing the storage case described in Claim 7 within the inner bag further. For instance, even when the fireproof safe installed at a high floor drops due to a fire, the contents may be protected from the high temperature heat caused by the fire and from the shock caused by the drop.
  • the adiabatic bag may be used in the outdoor in a cold district for instance.
