Description

  The present invention relates to a heat retaining container capable of transporting fresh products such as sea grapes and vegetables and plants such as flower buds while keeping them warm.

  Conventionally, when transporting fresh items such as sea grapes and vegetables, and plants to be packed such as flowers, in winter, there is a thermal insulation container to prevent the fresh products and plants from being damaged by low temperature outside air during transportation. Various are provided. For example, sea grapes (a kind of seaweed), which are mainly produced in southern countries such as Okinawa, lose their commercial value when the temperature falls below 12 ° C in winter consumption areas.

  Therefore, in winter, a heating element such as a disposable body warmer is housed and transported as a heating medium in a heat insulating container together with an item to be packed. For example, in the technique described in Patent Document 1, a storage portion for storing an object to be packed is formed in an outer box made of corrugated cardboard through which oxygen can flow, and an inner box made of foam is disposed. A heating element such as a disposable body warmer is disposed between the box and the inner box.

  In this technique, oxygen flows into the outer box from the joint or gap of the outer box made of corrugated cardboard, so that the heating element generates heat, and the heat retaining property of the packaged item in the inner box is ensured.

Utility Model Registration No. 3132387

  However, as shown in Patent Document 1, it is assumed that oxygen does not sufficiently flow from the outside of the outer box to the inside of the outer box at the seam and gap formed when assembling the outer box (thermal insulation container) from the cardboard board, It is conceivable that heat generation by the heating element cannot be sufficiently expected.

  In view of this point, it is conceivable to make a ventilation hole (through hole) in the heat retaining container which is an outer box so that oxygen can sufficiently flow into the inside, but when a through hole is simply provided, It is conceivable that cold air enters and its heat retention is impaired.

  The present invention has been made in view of such a point, and the object of the present invention is to supply oxygen sufficiently to the heating element while containing the heating element that generates heat by reacting with oxygen. It is another object of the present invention to provide a heat retaining container that can retain the heat retaining property of the heat retaining container.

  In order to solve the above-mentioned problems, a heat insulating container according to the present invention includes a container body formed with an opening that opens upward, and a lid that can be attached to cover the opening of the container body, In the state in which the lid is attached to the container body, a heat-retaining container is formed in which a housing space for housing an object to be packaged together with a heating element that generates heat by reacting with oxygen is formed. In the state where the thermal insulation container is attached, a through hole is formed in the side wall portion of the heat insulation container so as to communicate the outside of the heat insulation container and the accommodation space, and the side wall portion of the heat insulation container is viewed from the horizontal direction. In the side view, the accommodation space cannot be seen from the outside of the heat insulation container through the through-hole, and when the side wall portion of the heat insulation container is viewed obliquely downward with respect to the horizontal direction, The accommodation space from the outside through the through hole It looks like, wherein the through hole is formed.

  According to the present invention, since the through hole that communicates the outside of the heat retaining container and the accommodation space is formed in the side wall portion of the heat retaining container, the heat generated in the housing space from the outside of the heat retaining container through the through hole. Can supply oxygen to the body. Thereby, it can be made to react with the oxygen supplied through the through-hole, and a heat generating body can be heated.

  Furthermore, when the through hole is viewed from the side, the accommodation space cannot be seen from the outside of the heat insulation container through the through hole, and the accommodation space can be seen from the outside of the heat insulation container through the through hole when viewed from obliquely below. So that it is formed. As a result, the cold air flowing from the upper outside to the lower side of the heat insulation container is unlikely to flow along the through hole (along the obliquely downward direction), and the cold air outside the heat insulation container is taken into the accommodation space through the through hole. hard.

  Furthermore, the warm air obtained by the heat generation of the heating element in the heat insulation container housing space generally tends to flow from the bottom to the top of the heat insulation container. In the present invention, the above-described through hole is formed in the heat insulation container. Such warm air is unlikely to flow out from the accommodation space of the heat insulation container along the through hole (along the diagonally downward direction).

  As a result, while supplying oxygen sufficiently to the heating element accommodated in the accommodation space, it is difficult to be affected by the cold air outside the insulation container, and it is easy to keep the warm air in the accommodation space of the insulation container. The heat retention can be improved.

  Here, the upper wall surface forming the through hole may be, for example, a convex or concave wall surface as it goes to the accommodation space side, or may have a part of the wall surface along the horizontal direction. As long as the above-described through hole can be formed, the upper wall surface and the lower wall surface forming the through hole are not particularly limited.

  However, as a more preferable aspect, the upper wall surface that forms the through hole has an inclined surface that is inclined upward with respect to the horizontal direction as it proceeds toward the accommodation space. According to this aspect, since the upper wall surface forming the through-hole has the above-described inclined surface, when warm air flowing upward from the outside of the heat insulating container flows, this is along the inclined surface of the upper wall surface. It can be poured into the storage space.

  Furthermore, the inner wall surface of the side wall portion forming the accommodation space is not particularly limited as long as it can take in oxygen from the outside of the heat retaining container through the through hole. As a more preferable aspect, a plurality of groove portions are formed on the inner wall surface of the heat retaining container forming the accommodation space so as to be continuous with the through hole along at least the vertical direction of the inner wall surface. According to this aspect, the oxygen taken in from the through hole is guided along the plurality of groove portions formed along the inner wall surface of the side wall portion. Therefore, if a heating element is disposed in the portion where the plurality of grooves are formed, the groove serves as a passage for supplying oxygen, so that oxygen can be stably supplied to the heating element.

  Further, in the present invention, the number of through holes and the position thereof are not particularly limited, but as a more preferred aspect, at least a pair of the through holes are formed at positions facing each other with the accommodation space interposed therebetween, The plurality of groove portions are formed so as to go around the inner wall surface through the respective through holes.

  According to this aspect, since the plurality of groove portions are formed so as to circulate around the inner wall surface via the respective through holes, the groove portions are also formed on the upper and lower inner wall surfaces of the heat insulating container forming the accommodation space. Will be. As a result, oxygen taken in through the through-holes is also guided to the grooves formed along the upper and lower inner wall surfaces, so that the heating elements arranged on the upper and lower inner wall surfaces can be stably provided. Oxygen can be supplied. As a result, the inside of the accommodation space can be more uniformly kept warm.

The above-described through hole may be formed in the side wall portion of the container body. However, as a more preferable aspect, the through hole is formed by attaching the lid body to the container body. It is formed between the main body. According to this aspect, since it can be provided between the through hole and the container main body, that is, in the vicinity of the joint portion, the through hole can be easily formed in the heat retaining container during manufacturing.

  As a more preferable aspect, the lid and the container main body are formed with fitting portions that are fitted to each other in a state where the lid is attached to the container main body. With such a fitting portion, the lid can be fitted to each other with the lid attached to the container main body, so that the lid can be prevented from dropping from the container main body due to an impact or the like. Furthermore, when the container main body and the lid are integrated in a solid state by the fitting portion, the work of sticking the adhesive tape to the outer wall surface of the portion where they abut in order to integrate them is also omitted. Sometimes you can. Thereby, possibility that a through-hole will be block | closed with an adhesive tape becomes low.

  Furthermore, as a preferable aspect, the through-hole is formed on the bottom side of the heat retaining container with respect to the portion where the container body and the lid abut in a state where the lid is attached to the container body. . According to this aspect, since the through hole is formed on the bottom side of the heat insulating container with respect to the portion where the container main body and the lid are in contact, oxygen is supplied from the through hole to the portion of the accommodation space formed by the container main body. Easy to supply.

  As a more preferable embodiment of such a through-hole, the heat retaining container is provided with an adhesive tape on an outer wall surface of a portion where the container body and the lid body abut in a state where the lid body is attached to the container body. By sticking, the container body and the lid are integrated, and the packaged object is packed together with the heating element in the accommodation space, and the adhesive tape is attached to the through hole. It is formed on the bottom side of the heat retaining container with respect to the region.

  According to this aspect, when the adhesive tape is attached to the outer wall surface of the portion where the container main body and the lid body abut, the through hole is closer to the bottom surface side of the heat retaining container than the region where the adhesive tape is attached. Since it is formed, it is possible to prevent the through hole from being blocked with the adhesive tape.

  According to the present invention, the heat retaining property of the heat retaining container can be maintained while oxygen is sufficiently supplied to the heat generating element in a state where the heat generating element that generates heat by reacting with oxygen is accommodated.

[First Embodiment]
Below, with reference to FIGS. 1-7, the heat retention container 10 which concerns on 1st Embodiment is demonstrated.
The heat retaining container 10 according to the present embodiment is a container for storing fresh products such as sea grapes and vegetables and plants such as flower buds as packed objects, and transporting them while keeping them warm. The package will be described below with sea grapes as an example.

  As shown in FIG. 1, the heat retaining container 10 includes a container body 20 and a lid 30. The lid 30 is attachable so as to cover the opening 20e of the container body 20, and in the state where the lid 30 is attached to the container body 20, the accommodation space for accommodating the above-described packaged items inside. S is formed (see, for example, FIGS. 5 and 6).

  In addition, about the arrangement | positioning state of the disposable warmer 60 which is a heat generating body which generate | occur | produces heat by reacting with oxygen, the storage box 50 which accommodated the to-be-packaged goods (sea grapes) P, and the foam sheets 41-43 in this accommodation space S This will be described later in the method of using the heat retaining container 10 described later.

  Here, the container body 20, the lid body 30, and the storage box 50 described later are made of foamed resin. For example, polystyrene, styrene-modified polyolefin resin, high impact polystyrene, styrene-ethylene copolymer, styrene-anhydrous maleate. Various synthetic resin foams such as acid resins, polystyrene resins such as styrene-acrylonitrile copolymers, polyolefin resins such as polyethylene, polypropylene and ethylene-vinyl acetate copolymers, and polyester resins such as polyethylene terephthalate. Can be used.

  Among these, a molded body by bead foaming of polystyrene or styrene-modified polyolefin resin is preferably used. The styrene-modified polyolefin resin is obtained by impregnating and polymerizing a polyolefin resin particle with a styrene monomer. Among the styrene-modified polyolefin resins, a styrene-modified polyethylene resin is preferable, for example, a styrene component The ratio is 40 to 90% by weight, preferably 50 to 85% by weight, more preferably 55 to 75% by weight.

  Further, the expansion ratio of the polystyrene foam is preferably 30 to 80 times. The foamed resin used in the heat retaining container 10 of the present embodiment has a higher foaming ratio than the conventional one. By increasing the expansion ratio in this way, the structure is more easily crushed and has an excellent buffering effect when a load is applied compared to the conventional expansion ratio.

  As shown in FIGS. 1 and 2, the container body 20 has a rectangular shape in a top view having a long side and a short side, and four side wall portions 21 rising from a rectangular bottom portion 24 having a long side and a short side. Thus, an opening 20e opened upward is formed. With the lid 30 attached to the container main body 20, the side wall 21 of the container main body 20 becomes the side wall 11 of the heat insulating container 10, and the bottom 24 of the container main body 20 becomes the bottom 14 of the heat insulating container 10. In the present embodiment, the “inner wall surface of the heat insulating container forming the accommodation space” in the present invention is configured by the inner side surface 21a, the inner bottom surface 20a, and the back surface 30b of the lid body 30.

  Further, the opening edge 20d forming the opening 20e of the container body 20 is fitted to the fitting protrusion 38 formed on the back surface 30b of the lid body 30 with the lid body 30 attached to the container body 20. (See FIG. 3, FIG. 6 (a), (b), etc.).

  The lightening part 26 is formed so that the collar part 27 is formed in the vicinity of the opening edge 20d in the outer side surface 20c of the side wall part 21 of the container body 20. By providing the lightening portion 26, the weight of the container body 20 can be reduced. By providing the flange portion 27, the container body 20 (the heat retaining container) can be provided from the outer surface 10 c of the heat insulating container 10 through the flange portion 27. 10) can be easily lifted and transported.

  Further, as shown in FIG. 2, a stepped portion 29 is formed on the peripheral edge portion of the outer bottom surface 20 b of the container body 20. Specifically, when the heat insulating containers 10 are stacked in the vertical direction, the stepped portion 29 of the upper heat insulating container 10 is an engagement convex portion formed on the upper surface 30 a of the lid 30 of the lower heat insulating container 10. A stepped portion 29 is formed so as to engage with 39.

  As described above, the engagement convex portion 39 on the upper surface 30a of the lid body 30 and the stepped portion 29 formed on the bottom portion 24 of the container body 20 make the heat insulating container 10 in the vertical direction so that the short side and the long side coincide with each other. Acts as a positioning part when stacking.

  Further, each side wall portion 21 (specifically, the flange portion 27) on the long side of the container body 20 is formed with a notch portion 22, and the pair of side wall portions 21, 21 facing each other on the long side is formed. The formed notches 22 and 22 are formed at positions facing each other across the opening 20e.

  On the other hand, as shown in FIG. 3, at the edge on the long side of the back surface 30 b of the lid body 30, the lid body 30 is attached to the container body 20 and enters each notch 22 of the container body 20. A protruding edge 31 protruding downward is formed at the position.

  Thus, by providing the notch portion 22 of the opening edge 20d of the container body 20 and the protruding edge portion 31 of the back surface 30b of the lid body 30, the lid body 30 is attached to the container body 20 in a state where the lid body 30 is attached. A gap is formed between the notch 22 and the protruding edge 31. That is, as shown in FIGS. 4 and 5, a through hole 12 is formed in the side wall portion 11 of the heat retaining container 10 to communicate the outside of the heat retaining container 10 and the accommodation space S, and this is between the container main body 20 and the lid body 30. Will be formed.

  Specifically, the cutout portion 22 of the container body 20 has an inclined surface 22 a facing upward, and the inclined surface 22 a is upward with respect to the horizontal direction H as it goes inward of the container body 20. It is inclined to.

  On the other hand, the projecting edge portion 31 of the lid body 30 has an inclined surface 32b facing downward, and the inclined surface 32b is formed inside the lid body 30 with the lid body 30 attached to the container body 20. As it goes in the direction, it inclines upward with respect to the horizontal direction H.

  Thus, with the lid 30 attached to the container body 20, the inclined surface 22a of the container body 20 and the inclined surface 32b of the lid body 30 are spaced apart and arranged in parallel. The inclined surface 22a of the container body 20 becomes the lower wall surface 12a that forms the through-hole 12, and the lower wall surface 12a is inclined downward with respect to the horizontal direction H as it moves toward the accommodation space S side. On the other hand, the inclined surface 32 b of the lid 30 serves as the upper wall surface 12 b that forms the through hole 12.

  Further, as shown in FIGS. 5 and 7A, the through-hole 12 formed in the heat insulating container 10 is formed outside the heat insulating container 10 in a side view when the side wall portion 11 of the heat insulating container 10 is viewed from the horizontal direction H. When the side wall 11 of the heat insulating container 10 is viewed obliquely downward R with respect to the horizontal direction H, the housing space S cannot be seen through the through hole 12 from the outside of the heat insulating container 10 through the through hole 12. It is formed so that the accommodation space S can be seen.

A method of using the heat retaining container 10 configured as described above will be described below.
First, as shown in FIG. 1, the disposable body warmer 60 is disposed on the inner bottom surface 20 a of the container body 20, and the foamed sheet 43 made of sheet-like flexible foamed urethane or the like is disposed thereon.

  Next, a plurality (specifically, 16 pieces) of storage, which includes a box main body 52 in which the sea grapes P are stored and a box lid 51 that is attached so as to cover the opening of the box main body 52, is stored in the storage space S. The boxes 50 are aligned and arranged in two stages.

  Next, a foam sheet 42 made of urethane foam or the like is disposed so as to surround the side surfaces of the plurality of storage boxes 50 arranged, the inner side surface 21 a below the notch 22 of the container body 20, and the foam sheet 42. The disposable body warmer 60 is disposed between the two. Next, the foam sheet 41 made of urethane foam or the like is disposed so as to cover the upper surfaces of the plurality of storage boxes 50 arranged, and the disposable body warmer 60 is disposed thereon.

  In this manner, the lid 30 is attached to the container body 20 in a state where the sea grape P stored in the storage box 50 together with the disposable body warmer 60 is housed in the container body 20 (FIGS. 5 and 6A). , (B)). Thereby, the fitting protrusion 38 of the back surface 30b of the lid 30 is fitted to the inner side surface 21a in the vicinity of the opening edge 20d of the container body 20, and the sea grape P together with the disposable body warmer 60 is placed in the accommodation space S of the heat retaining container 10. Will be packed.

  Here, in this embodiment, as shown in FIG. 6B, the lid body 30 is fitted to the container body 20 by the fitting protrusions 38 on the back surface 30 b of the lid body 30. In addition, for example, as shown in FIG. 6C, a fitting groove 38 </ b> A is formed on the back surface 30 b of the lid body 30, and the fitting protrusion that fits the fitting groove 38 </ b> A on the container body 20. Article 28A may be formed.

  Thereby, the container main body 20 and the lid body 30 are in a firm state due to the mutual fitting of the fitting portion including the fitting concave groove 38A and the fitting protrusion 28A. Integrated. Therefore, in order to integrate them, it is possible to omit sticking the adhesive tape to the outer wall surface of the portion where they abut. Thereby, it can avoid that the through-hole 12 is block | closed with an adhesive tape.

  According to the heat insulating container 10 packed in this way, as shown in FIGS. 5 and 7A, a through-hole that communicates the outside of the heat insulating container 10 and the accommodation space S with the side wall portion 11 of the heat insulating container 10. 12 is formed. Thereby, oxygen can be supplied to the disposable body warmer 60 arranged in the accommodation space S from the outside of the heat insulating container 10 through the through hole 12. As a result, the disposable body warmer 60 can generate heat by reacting with oxygen supplied through the through hole 12.

  In particular, in this embodiment, the through-hole 12 is formed on the bottom side of the heat retaining container 10 with respect to the portion where the container body 20 and the lid body 30 abut with the container body 20 attached to the lid body 30. Therefore, it is easy to supply oxygen from the through hole 12 to the accommodation space S formed by the container body 20.

  Furthermore, when the through-hole 12 is viewed from the side in the horizontal direction H, the accommodation space S is not visible from the outside of the heat-retaining container 10 through the through-hole 12, and when viewed from the diagonally lower direction R, It is formed so that the accommodation space S can be seen through the through hole 12 from the outside. As a result, cold air generally tends to flow downward from the upper outside of the heat retaining container 10. In this embodiment, such cold air hardly flows along the through-hole 12 (in the diagonally downward direction R). The cold air outside the heat retaining container 10 is difficult to be taken into the accommodation space S through the through hole 12.

  Further, the warm air obtained by the heat generated by the disposable body warmer 60 in the accommodation space S of the heat insulation container 10 generally flows easily from the lower side to the upper side of the heat insulation container 10, and the above-described through hole 12 is formed in the heat insulation container 10. Therefore, it is difficult for such warm air to flow out from the accommodation space of the heat retaining container 10 along the through hole 12 (along the diagonally downward direction R) to the outside.

  As a result, while supplying oxygen sufficiently to the disposable body warmer 60 accommodated in the accommodation space S, the warm air in the accommodation space S of the heat insulation container 10 is easily retained without being affected by the cold air outside the heat insulation container 10. Therefore, the heat retaining property of the heat retaining container 10 can be improved.

  Furthermore, since the upper wall surface 12b that forms the through hole 12 is an inclined surface 32b that is inclined upward with respect to the horizontal direction H as it advances toward the accommodation space S, warm air flows upward from the outside of the heat retaining container 10. If it is, warm air can flow along the inclined surface 32b of the upper wall surface 12b and can be taken into the accommodation space S.

  Here, the through hole 12 cannot be seen from the outside of the heat insulating container 10 through the through hole 12 in the side view when viewed from the horizontal direction H, and the heat insulating container 10 when viewed from the diagonally downward direction R. What is necessary is just to form so that the accommodation space S can be seen through the through-hole 12 from the outside.

  Therefore, as in the modification shown in FIG. 7B, the upper wall surface 12b that forms the through hole 12 may be formed so as to protrude outward from the lower wall surface 12a. Thereby, it becomes easy to take in the warm air which goes upwards from the exterior of the heat insulation container 10 in a heat insulation container.

  Moreover, as shown in FIG.7 (c), the lower wall surface 12a may incline below as it goes to the accommodation space S side. Thereby, since the throttle structure can be formed between the upper wall surface 12b and the lower wall surface 12a, it is difficult for the warm air in the housing space S to escape to the outside. Further, as shown in FIG. 7D, a part of the upper wall surface 12b may be an inclined surface 32b, and a flat surface 12c along the horizontal direction H may be formed on a part thereof.

[Second Embodiment]
Below, with reference to FIG. 8, FIG. 9, the heat retention container which concerns on 2nd Embodiment is demonstrated. The difference from the first embodiment is that a plurality of groove portions 25 are provided on the inner side surface 21a and the inner bottom surface 20a of the container body 20A, and a plurality of groove portions 35 are provided on the back surface 30b of the lid 30A. Therefore, the same components as those of the heat insulation container of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, as shown in FIGS. 8A and 8B, the pair of inner side surfaces 21a of the container main body 20A of the storage space S (the heat retaining container 10A) are opposed to the upper and lower sides of the inner side surface 21a. A plurality of groove portions 25, 25,... Are formed along the direction so as to be continuous with the through hole 12 (notch portion 22). Further, as shown in FIG. 8B, the grooves 25 formed on the opposing inner side surface 21a are continuously formed on the inner bottom surface 20a. Further, as shown in FIG. 9, a plurality of groove portions 35, 35,... Are formed on the back surface 30 b of the lid 30 </ b> A so as to connect a pair of opposing protruding edge portions 31.

The groove portions 25 and 35 are formed so as to go around the inner wall surface (the inner side surface 21a of the container main body 20, the inner bottom surface 20a, and the back surface 30b of the lid 30) of the heat retaining container 10A.

  In this way, the oxygen taken in from the through holes 12, 12 has a plurality of groove portions 25, 25, ... will be guided along. The plurality of grooves 25, 25,... Are continuously formed on the inner bottom surface 20a, so that oxygen is also guided to the bottom 24 (below the accommodation space). Further, since the plurality of grooves 35, 35,... Are also formed on the back surface 30b of the lid 30A, oxygen taken from the through holes 12, 12 along these grooves 35, 35,. It is also guided above the accommodation space S.

  As a result, a plurality of protrusions formed between the portions (specifically, the groove portions 25, 25 (35, 35)) formed by the plurality of groove portions 25, 25,... (35, 35,...). If the disposable body warmer 60 is disposed in the strip), the groove 25 (35) becomes a passage for supplying oxygen, so that oxygen can be stably supplied to the disposable body warmer 60.

  In particular, oxygen can be stably supplied to the disposable body warmer 60 disposed in the vicinity of the upper inner wall surface (the back surface 30b of the lid) and the lower inner wall surface (the inner bottom surface 20a of the container body 20) of the heat insulation container. Therefore, the inside of the accommodation space S can be more uniformly kept warm by the disposable body warmer 60.

[Third Embodiment]

The difference from the first embodiment is the shape of the notch 22B of the container main body 20B and the protruding edge 31B of the lid 30B, and is the position of the through hole 12B of the heat retaining container 10B. Therefore, the same components as those of the heat insulation container of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, as shown in FIG. 11, the heat insulating container 10B has an adhesive tape on the outer wall surface of the portion 10g where the container body 20B and the lid body 30B abut with the container body 20B attached to the lid body 30B. Stick T. As a result, the container body 20B and the lid body 30B are integrated, and the sea grape P stored in the storage box 50 together with the disposable body warmer 60 is packed in the storage space.
