Description

Carrying aid, bag equipped with carrying aid, and method of using same

[0001] The present invention relates to an aid for carrying food in a bag and a bag provided with the aid.

[0002] In recent years, there has been an increase in demand for food delivery services that deliver ordered food directly from the store to the customer, but the food delivered by these services tends to taste inferior to freshly made food. This is because the food's temperature drops compared to freshly made food and it absorbs moisture from the surrounding area, and the deterioration in taste is particularly noticeable in fried foods.

[0003] Publication No. 3191693

[0004] Patent Document 1 describes a container for heating food using a heating element without moistening it. However, such a container is not suitable for delivery purposes because it cannot be reused, and there is a problem that the food is overheated, which causes a deterioration in taste.

[0005] In view of the above problems, the present invention aims to provide an auxiliary device that can be easily used when carrying food in a bag and that can maintain the taste of food as much as possible, and a bag equipped with such an auxiliary device.

[0006] The present invention solves the above-mentioned problems by providing a bag with a moisture-absorbing top panel that supports items and a support part that supports the top panel at a position away from the bottom of the bag. The moisture-absorbing panel and support part prevent the items from cooling or absorbing moisture, thereby extending the time that the food's flavor is maintained.

[0007] In a preferred form of the present invention, the support part has a hollow structure provided at the bottom of the top panel, and further comprises a breathable holding part that covers the top panel and the hollow structure and holds them together, so that the support part is lightweight and, as it is one piece, can be easily attached to the bag, and a highly insulating space can be created between the bottom of the bag and the item.

[0008] In a preferred embodiment of the present invention, the support portion has a hanging portion that hangs and supports the top panel, so that the support portion can be attached to various bags regardless of their shapes.

[0009] In a preferred embodiment of the present invention, the top panel and the hollow structure are breathable, so that air convection occurs below the top panel, enhancing the moisture absorption effect of the top panel.

[0010] In a preferred embodiment of the present invention, a heat storage section with high thermal conductivity is provided on the top panel. At least a portion of the heat storage section is exposed to the outside of the holder. The heat storage section is fixed in a state where it protrudes from the top panel and supports a food container for storing food. This allows the heat storage section 4 to absorb the heat of the food and make it less likely for steam to be generated, thereby maintaining the food's flavor.

[0011] The present invention relates to a bag having a carrying aid attached to its bottom surface, the carrying aid comprising a moisture-absorbent top panel for supporting items, a hollow structure provided below the top panel, and a holder for covering and holding the top panel and the hollow structure together. The inner periphery of the bag is covered with side panels that are more moisture-absorbent than the outer periphery of the bag. This allows for more effective maintenance of food taste, utilizing the moisture-absorbency of the bag itself in addition to the carrying aid.

[0012] The present invention also provides a method for using a bag, which includes a step of placing food on the top panel and a step of injecting dry air into the bag, thereby adjusting the internal environment of the bag and maintaining the taste of food for a longer period of time, particularly when used continuously.

[0013] The present invention, which solves the above problems, can provide an auxiliary device that can be easily used when carrying food in a bag and that helps maintain the food's flavor as much as possible, and a bag equipped with such an auxiliary device.

[0015] The following describes the carrying aid X according to each embodiment of the present invention with reference to the drawings. The description will be given in detail in the order of the configuration of the embodiment, the method of implementation, and other examples. Note that the embodiments shown below are examples of the present invention, and the present invention is not limited to the following embodiments. Furthermore, the term "approximately" in the specification is a concept that means that the shape that follows is chamfered or rounded, and that the elements that make up the shape are deformed or changed in length within a range that does not impair the purpose of the configuration.

[0016] Hygroscopicity refers to the ability of a material to absorb moisture from the air. For comparison, the weight of water vapor that can be absorbed relative to the mass of the material or the rate at which the material absorbs water vapor can be used, and the comparison can be made using the moisture absorption rate (%) or moisture absorption rate (percent per minute) (% / min) obtained by a test specified in JIS L 1954, for example.

[0017] Furthermore, breathability refers to the property of a material to allow air to pass through, and can be compared, for example, by the magnitude of the air permeability (cm3 / (cm2·s)) defined by JIS L 1096 A (Fragile type method).

[0018] The moisture-absorbing heat generation property indicates the property of a material to generate heat when it absorbs water vapor or moisture in the air, and can be compared, for example, by the maximum moisture-absorbing heat generation temperature (°C) obtained by the test method specified in JIS L 1952 (ISO 18782).

[0019] First Embodiment The present invention relates to a carrying aid X comprising a moisture-absorbing top panel 1 for supporting an item and a support portion 2 for supporting the top panel at a position spaced apart from the bottom of a bag. In this embodiment, as shown in FIGS. 1 to 4 , the carrying aid X comprises the moisture-absorbing top panel 1 located on the bottom of a bag Y for supporting an item, a hollow structure 21 provided below the top panel 1 as the support portion 2, and a breathable retaining portion 3 for covering and holding the top panel 1 and hollow structure 21 together. The retaining portion 3 further retains a heat storage portion 4 disposed on the top panel 1 for storing heat from the item. A food container 5 containing food M is placed on the carrying aid X. Note that Figure 1 is a schematic oblique view of the carrying aid X, Figure 2 is a schematic oblique view of the carrying aid X when a food container 5 is placed on it, Figure 3 is a schematic plan view showing the carrying aid X attached to a bag Y, with the bag lid 63 omitted, and Figure 4 is a perspective view of the carrying aid X with a food container 5 placed on it attached to a bag Y.

[0020] Bag Y is a generally box-shaped bag primarily used for delivery purposes, with carrying aid X attached to its bottom surface. Bag Y has a bag body 60, a bag bottom surface 61 that forms the bottom surface of bag body 60, bag sides 62 that rise up to surround the periphery of bag bottom surface 61, a bag lid 63 that forms the top surface and can be opened and closed, and a shoulder strap 64 that allows the user to carry the bag over their shoulder.

[0021] The top panel 1 is a rectangular plate-like member whose surface is substantially the same shape as the bag bottom 61 and whose size is substantially the same as or slightly smaller than the bag bottom 61, and is arranged to cover the bag bottom 61. The top panel 1 is hygroscopic and breathable, and is arranged to be more hygroscopic and breathable than at least the components on the inner periphery of the bag Y, and preferably more hygroscopic and breathable than the fabric material (e.g., polyester fabric) forming the bag Y. This allows the top panel 1 to absorb water vapor inside the bag Y and improve the preservation performance of the food M. Furthermore, the top panel 1 is preferably more hygroscopic than the hollow structure 21 and the holding portion 3, preventing moisture from transferring to other components. The top surface of the top panel 1 is substantially horizontal, allowing items such as the heat storage portion 4 and the food container 5 to be placed on it.

[0022] In this embodiment, the top panel 1 contains a hygroscopic fiber, preferably a nonwoven fabric, which provides both hygroscopicity and breathability. Preferably, the top panel 1 is made of a highly hygroscopic fiber with a hygroscopicity of 20% or more, and specifically, wool, cotton, acrylate, or Moisfine (registered trademark) is envisioned.

[0023] Furthermore, the top panel 1 has moisture absorption and heat generation properties, which further enhances the heat retention performance of the food M. The moisture absorption and heat generation properties of the top panel 1 are higher than at least the components on the inner periphery of the bag Y or the fabric material of the bag Y, and preferably higher than the hollow structure 21 and the holding portion 3, which further enhances the heat retention performance inside the bag Y.

[0024] The hollow structure 21 is a member containing many cavities inside, which supports the top panel 1 on its upper surface, and is rigid enough that it will not deform even when the top panel 1 and food container 5 are placed on it. The shape and size of the surface of the hollow structure 21 are substantially the same as those of the top panel 1, but it is thicker than the top panel 1. In this way, the hollow structure 21 has a predetermined thickness, and by retaining air inside, it improves the insulation between the bag bottom surface 61 and makes it easier to maintain the temperature of the food M.

[0025] In this embodiment, the hollow structure 21 is made up of multiple linear plastic strands with a certain degree of rigidity that are intertwined with one another, forming numerous gaps. This allows the hollow structure 21 to have breathability regardless of orientation. This breathability is at least higher than that of the fabric material (e.g., polyester fabric) that forms the bag Y, which causes convection inside the bag Y as shown in Figure 5, making it easier for water vapor to be absorbed by the moisture-absorbing material in the top panel 1, etc. The hollow structure 21 is shown in photographs in Figures 5 to 7.

[0026] Preferably, the linear plastic of the hollow structure 21 is made of hollow fiber. That is, by making the hollow structure 21 of tubular fiber, air can be retained inside the fiber, further improving heat insulation and further reducing weight. It is also preferable to cover the hollow structure 21 with a breathable and moisture-permeable fabric material so that the ends of the linear material do not interfere with the bag Y.

[0027] The retaining portion 3 is a mesh material that covers the top panel 1 and the hollow structure 21 to hold them together, and the inside of the retaining portion 3 is exposed through the mesh, allowing ventilation and moisture to pass between the inside and outside. In this embodiment, the retaining portion 3 is sewn together while simultaneously surrounding the entire outer periphery of both components with the top panel 1 placed on the top surface of the hollow structure 21.

[0028] The heat storage section 4 is a member that comes into contact with the food container 5 during use and absorbs and stores heat from the food container 5 or food M. Its surface area is at least smaller than that of the food container 5, preventing the food M inside from cooling down. The heat storage section 4 is a member with a higher thermal conductivity than at least the top panel 1 and the food container 5. In this embodiment, the heat storage section 4 is made of aluminum or an aluminum-containing alloy, which has a relatively high specific heat, thereby increasing its heat capacity and improving its heat storage performance. The heat storage section 4 is also at least thicker than the retaining section 3, and preferably thicker than the thickness of the top panel 1, thereby increasing its volume and further increasing its heat capacity. In this embodiment, the heat storage section 4 is cylindrical, with a diameter longer than half the short side of the top panel 1 but smaller than the short side.

[0029] The heat storage unit 4 is located approximately at the center of the top surface of the top panel 1, and the holder 3 holds the heat storage unit 4 together in this state. In the embodiment, the heat storage unit 4 is fixed to a predetermined position on the top panel 1 by sewing the top panel 1 and the holder 3 together along the periphery of the heat storage unit 4 (the dotted line in FIG. 3 indicates the sewing position). This prevents the holder 3 from being stretched around the heat storage unit 4 and makes it easier to hold the food container 5. However, the top panel 1 and the heat storage unit 4 may also be simply fixed by adhesive. Alternatively, the heat storage unit 4 may be embedded inside the top panel 1 so that the top surface is exposed to the outside, thereby being adjacent to the hollow structure 21. In this case, thermal convection by the heat storage unit 4 is more likely to occur within the hollow structure 21, improving water vapor absorption performance. In the embodiment, the heat storage unit 4 protrudes from the top panel 1, but if embedded, it may be provided flush with the top panel 1.

[0030] The food container 5 is a container for storing food M, and is bucket-shaped in this embodiment. The food container 5 has a circular container bottom 51 on which the food M is placed, a substantially cylindrical container side 52 that surrounds and adds height to the container bottom 51, and a container lid 53 that is a lid attached to the upper end of the container side 52. The container bottom 51 is located at a distance from the lower end surface of the container side 52. The food M is assumed to be cooked, particularly fried food.

[0031] As shown in FIG. 5 , the food container 5 is held in place by the heat storage unit 4. That is, the diameter of the container bottom 51 is set larger than at least the diameter of the heat storage unit 4, and the position of the container relative to the bag Y is determined by hooking onto the heat storage unit 4, which protrudes from the top panel 1. Furthermore, the inner periphery of the lower end of the container side 52 and the outer periphery of the heat storage unit 4 are approximately the same shape and size, allowing the food container 5 to be supported in a predetermined position by the carrying aid X. Furthermore, the protruding height of the heat storage unit 4 relative to the top panel 1 is greater than the distance from the container bottom 51 to the lower end of the container side 52, thereby bringing the container bottom 51 and the heat storage unit 4 into close contact and support, allowing the heat of the food container 5 to be efficiently transferred to the heat storage unit 4. Note that FIG. 5 is a schematic cross-sectional view of the A-A cross section of the food container 5 in a placed position.

[0032] The bag bottom 61, side body 621 of bag side 62, and lid body 631 of bag lid 63, which form the surfaces of bag Y, each have a waterproof fabric material such as polyester on the periphery, and a heat insulating material is provided inside to maintain the taste of the food M inside. In addition, rigid reinforcing plates may be provided at predetermined positions on bag bottom 61 and bag side 62 to maintain the shape of bag Y.

[0033] The bag bottom 61 is made of a substantially rectangular material large enough to contain at least the entire carrying aid X, and may have a hook-and-loop fastener on its top surface to connect to the carrying aid X. The bag side 62 is made of a material whose edge connects to the edge of the bag bottom 61. The bag lid 63 is made of a material that connects to a connecting edge S, which is one of the upper edges of the bag side 62, and is rotatable relative to the bag side 62 around the connecting edge S as an axis.

[0034] The bag side 62 has four plate-shaped side bodies 621 that form the side of the bag Y, side panels 622 provided on the inner surface of the side bodies 621, and side holding portions 623 that hold the side panels 622 on the inner surface of the side bodies 621.

[0035] The side panel 622 is a plate-like member arranged to cover almost the entire inner periphery of the side body 621, and has at least higher moisture absorption and moisture-absorbing heat-generating properties than the side body 621. Preferably, the side panel 622 is made of the same material as the top panel 1. This increases the area of ​​the moisture-absorbing material that comes into contact with water vapor diffused by convection, thereby achieving better preservation performance for the food M.

[0036] The side holding portion 623 is a mesh-like member that covers the entire side panel 622, and is sewn to the side body 621 at its edges to hold the side panel 622 between it and the side body 621. The holding method is not limited to using the side holding portion 623, and the side panel 622 may also be held by hook-and-loop fasteners, adhesive, a safety pin, or the like.

[0037] The bag lid 63 has a plate-shaped lid body 631 that forms the top surface of the bag Y, a lid surface panel 632 provided on the inner side of the lid body 631, a lid surface holding portion 633 that holds the lid surface panel 632 to the lid body 631, and a flap 634 that extends outward from the edge of the lid body 631.

[0038] The lid panel 632 is a plate-like member arranged to cover almost the entire inner periphery of the lid 631, and has higher hygroscopicity and hygroscopic heat-generating properties than the lid 631, and is preferably made of the same material as the top panel 1. This improves the preservation performance of the food M by capturing water vapor that moves upward due to thermal convection.

[0039] The cover surface holding portion 633 is a mesh-like member that covers the entire cover surface panel 632, and is sewn to the side body 621 at its edges to hold the cover surface panel 632 between the cover body 631. As with the side panel 622, the holding method may be changed.

[0040] As shown in Figures 4 and 5, the flap 634 has a hook-and-loop fastener joint C on the inside, and when in use, it joins with the hook-and-loop fastener joint C provided on the upper outer side of the side panel 622, making it easy to open and close the bag Y and keeping the bag lid 63 closed, forming an enclosed space inside.

[0041] A method for carrying out the present invention will be described in detail below with reference to the drawings. The present invention is carried out by a user who carries food M in a bag Y. The method for carrying out the present invention is an example, and the method for carrying out the present invention is not limited to this example. The order of steps may be reversed, or some steps may be omitted.

[0042] First, the user heats and cooks the food M and places it in the food container 5. Then, as a placing step, the food container 5 is placed on the carrying aid X as shown in Figure 2. This causes some of the heat contained in the food M to be stored in the heat storage section 4, maintaining a temperature that provides excellent taste for a long period of time. In addition, the temperature of the food M drops, suppressing the generation of steam (water vapor) from the food M and maintaining this temperature for a long period of time. This allows the moisture-absorbing heat-generating material to more easily absorb moisture, improving heat retention performance and preventing the food M from becoming damp.

[0043] Next, the user injects dry air as the injection step. The humidity of this dry air is preferably at least 50% or lower, and the temperature is preferably the same as or higher than that of the food M (especially 60°C to 80°C). This further improves the heat retention performance.

[0044] Next, the user attaches the carrying aid X with the food container 5 attached to the bottom of the bag Y, as shown in FIG. 6 , closes the container lid 53, and holds and transports the food M. FIG. 6 is a schematic cross-sectional view showing the bag lid 63 partially open, ready to attach the carrying aid X and the food container 5. At this time, as shown in FIG. 5 , heat generated by the heat storage section 4 and the food container 5 causes thermal convection around the food container 5 and inside the hollow structure 21, stirring up moisture inside the bag Y and making it easier for the top panel 1, side panel 622, and lid panel 632 to absorb moisture. This heats the bag Y through moisture absorption and further dries the interior, improving heat retention and preventing the food M from becoming damp. Alternatively, the user may place the food container 5 on the carrying aid X already attached inside the bag Y.

[0045] After use, the user opens the bag lid 63 and preferably removes the carrying aid X, allowing the moisture absorbed by each panel to be released and ready for the next use. As described above, an aid that can be easily used when putting food in the bag Y and transporting it can maintain its flavor for a long time can be used.

[0046] As an example, food weighing 800 g and at a temperature of 60°C was stored in a 35 L bag Y having a top panel 1 and side panels 622 made of Moisfine (registered trademark). The bag Y was filled with dry air at a temperature of 60°C and a humidity of 10% by performing an injection process using dry air. After the bag Y was closed, the changes in the environment inside the bag Y were measured in an environment with an outside temperature of 15°C and a humidity of 58%. As a result, even after one hour, the temperature inside the bag was 47°C and the humidity was 44.7%.

[0047] Second Embodiment A carrying aid X according to a second embodiment of the present invention will be described in detail below with reference to FIG. 7 . Components similar to those in the first embodiment are designated by the same reference numerals and will not be described again. FIG. 7 is a schematic cross-sectional view illustrating a state in which the bag lid 63 is half-open and the carrying aid X and food container 5 according to the embodiment are about to be attached. In this embodiment, the carrying aid X is attached to the bottom surface of the bag Y and includes a moisture-absorbing top panel 1 for supporting items, a hollow structure 21 provided below the top panel 1, and a holding section 3 that covers and holds the top panel 1 and hollow structure 21 together. The holding section 3 further holds a heat storage section 4 that is disposed on the top panel 1 and stores heat from the items, and a sub-panel A, which is a moisture-absorbing panel further provided on the top panel 1.

[0048] The sub-panel A has a sub-panel main body A1, which is a moisture-absorbent plate-like member, and an upright plate A2 that supports the sub-panel main body A1 so that it stands upright. This allows the food container 5 to be surrounded by moisture-absorbent material, maximizing the moisture absorption (heat generation) effect, even if the bag Y does not have a side panel 622 inside.

[0049] The sub-panel body A1 is a plate-like material that is sized to correspond to the width and height of the side body 621 of the bag Y, and is moisture-absorbent and breathable, and is provided so as to have higher moisture-absorbent and breathable properties than at least the components on the inner periphery of the bag Y, and preferably than the fabric material (e.g., polyester fabric) that forms the bag Y. Preferably, it is made of the same material as the top panel 1.

[0050] The standing plate A2 is a plate material that is joined by adhesive or the like along the sub-panel body A1, is located on the outside of the sub-panel body A1, and its surface is formed to be approximately the same size as or slightly larger than the sub-panel body A1. The standing plate A2 has a rigidity at least higher than that of the sub-panel body A1, and is preferably made of a resin material with high insulating properties. This ensures heat retention performance while preventing the sub-panel body A1 from tilting and reducing the storage space.

[0051] In this embodiment, the sub-panel A has multiple sub-panel bodies A1 arranged to surround the top panel 1, with the lower end of each sub-panel body A1 located on the same plane as the lower end of the hollow structure 21 and the upper end extending above the top panel 1, with the height being approximately the same as the bag side surface 62. This increases the area of ​​the moisture-absorbing panel, contributing to dehumidification and heat retention.

[0052] The holding portion 3 holds the above-mentioned members together, and it is preferable that the members including the holding portion 3 are appropriately sewn or glued together to maintain a constant shape.

[0053] The sub-panel A may further include another openable panel located opposite the top panel 1. In this case, a handle may be attached to the top surface of the carrying aid X. As long as the top panel 1 is accessible, the sub-panel A may be formed in any shape, such as a rectangular parallelepiped with one side removed.

[0054] When using this carrying aid X, as shown in Figure 7, a container containing food M is stored on the top panel 1, and this is then attached to the bag Y. This allows moisture absorption and heat generation even if there are no panels on the sides of the bag Y.

[0055] Third Embodiment A carrying aid X according to a second embodiment of the present invention will be described in detail below with reference to Fig. 8. Components similar to those in the first embodiment are designated by the same reference numerals and will not be described again. Fig. 8 is a schematic cross-sectional view of a bag Y equipped with the carrying aid. In this embodiment, the carrying aid X has a moisture-absorbing top panel 1 that supports an item at the bottom of the bag Y, and a support portion 2 that supports the top panel 1 in the air. Furthermore, a holding portion 3 is provided to simultaneously surround the top panel 1 and a heat storage portion 4 that stores heat from the item.

[0056] In this embodiment, the support portion 2 is a hanging portion 22 that hangs components including the top panel 1. The hanging portion 22 has a hanging hook 221 that can be temporarily fixed to the bag Y, and a hanging string 222 that connects the hanging hook 221 to the component. While at least two hanging portions 22 are provided to support the top panel 1 in midair, three or more hanging portions 22 are preferably provided to stably support the top panel 1.

[0057] The hanging hook 221 is a hook that is provided so as to be able to be engaged with the upper end of the side body 621, and is thin enough not to interfere with the space between the side body 621 and the cover body 631, and is able to connect to the hanging string 222. The hanging hook 221 may be configured to be connected to the surface of the side body 621, as long as it is connectable to the hanging string 222.

[0058] The hanging string 222 is a cord-like body having one end connected to the hanging hook 221 and the other end connected to the edge of the top panel 1 or the holding portion 3, and is used to hang materials including the top panel 1. When a sub-panel A is provided as in the second embodiment, it is preferable that the other end be connected to the upper end of the standing plate A2. The hanging string 222 may include a part that allows its length to be adjusted so that it can accommodate bags Y of various heights.

[0059] As a modified example, holes for fitting and holding food containers 5 of various shapes may be provided on the top surface of the carrying aid X. Furthermore, the shape of the heat storage section 4 is not limited to the above, and may be changed to a cylindrical shape that supports the food container 5 on the inner circumferential surface, or a protrusion that supports the food container 5 by sandwiching it between protrusions, etc.

[0060] The support portion 2 may have any structure or shape as long as it can support the top panel 1 in the air. For example, as shown in Figure 9(a), the support portion 2 may be a plurality of needles that protrude vertically downward from the surface of the top panel 1, or the holding portion 3 may be a wire mesh that is provided to maintain a predetermined shape such as a rectangular parallelepiped. Also, as shown in Figure 9(b), magnets may be provided on the top panel 1 and the bottom surface of the bag Y as the support portion 2, and the top panel 1 may be supported in the air by opposing the same magnetic properties.

[0061] Furthermore, the support part 2 is a hollow structure 21 provided below the top panel 1, and further includes a breathable holding part 3 that covers and holds the top panel 1 and hollow structure 21 together, making installation and storage easy. On the other hand, the support part 2 is a hanging part 22 that suspends and supports the top panel 1, making it easy to attach to various bags.

[0062] Furthermore, the top panel 1 and the hollow structure 21 are both breathable, and by facilitating the generation of air convection below the top panel 1, the possibility of water vapor hitting the top panel 1 is increased, thereby enhancing the moisture absorption effect.

[0063] Furthermore, the holding unit 3 further holds the heat storage unit 4, which has a higher thermal conductivity than the top panel 1, on the top panel 1, thereby conducting the heat of the food M to the heat storage unit 4, lowering the temperature of the food M, suppressing the generation of water vapor, and improving heat retention. This effect can be further improved by exposing at least a part of the heat storage unit 4 to the outside of the holding unit 3.

[0064] In addition, the heat storage section 4 is fixed in a protruding state from the top panel 1 and supports the food container 5 in which the food M is stored, which makes it easier for the heat storage section 4 to come into contact with the food container 5, increasing the amount of heat transferred from the food M and preventing the food container 5 from tipping over inside the bag Y.

[0065] Furthermore, by covering the bag side surface 62 with the side panel 622, which has higher moisture absorption than the outer surface of the bag Y, the amount of moisture that can be absorbed is increased, improving moisture absorption and moisture absorption heat resistance, and improving the ability to retain the flavor of food. The lid surface panel 632 further improves this effect.

[0066] In addition, by including a loading process of placing the food container 5 on the top panel 1 and an injection process of injecting dry air into the inside of the bag Y, it is possible to improve the heat retention and moisture absorption performance, and by performing this process particularly when the bag is used continuously, it is possible to maintain the top panel 1 in good condition.
