Description

The present invention relates to a food delivery set for delivering food in a supercooled state, and a food delivery system using the food delivery set.

2. Description of the Related Art Conventionally, when delivering food such as fish or meat, frozen delivery is sometimes performed in which the food is delivered in a frozen state in a freezer. When food is delivered by frozen delivery, the water contained in the food may freeze and expand. In that case, the cells of the food may be destroyed due to the expansion, and the quality of the food may be impaired. Therefore, in recent years, in order to solve these problems, technologies have been proposed to store and deliver food in a supercooled state. For example, Patent Document 1 discloses a refrigerator that can store food in a supercooled state. This refrigerator includes a box-shaped frame that forms a supercooled storage chamber, and a mounting section that is provided inside the frame and on which food is placed.

When food is in a supercooled state, if vibration is applied to the food, this may trigger freezing of the food. Therefore, in order to maintain the supercooled state of the food, it is necessary to suppress the vibrations applied to the food. In this regard, in the refrigerator of Patent Document 1, the placing section on which food is placed is provided to the frame via a buffer means such as rubber or a spring. Therefore, external vibrations applied to the refrigerator are suppressed from being transmitted to the food, and as a result, the supercooled state of the food can be suitably maintained.

Japanese Patent Application Publication No. 2013-148326

By the way, in the technique of Patent Document 1, a dedicated refrigerator is essential to keep food in a supercooled state. However, such a refrigerator would be expensive and would be difficult to introduce.

The main object of the present invention is to provide a food delivery set and a food delivery system that make it possible to deliver food in a supercooled state without using a dedicated refrigerator to maintain the supercooled state. be.

In order to solve the above problems, the food delivery set of the present invention has the following features:
A food delivery set for delivering food in a supercooled state,
a shipping box containing the food;
a cold storage material provided inside the delivery box;
a heat transfer pack provided inside the delivery box for transmitting cold heat of the cold storage material to the food;
The heat transfer pack is configured by filling a bag with a heat transfer liquid set at a freezing point that does not solidify due to the cold heat of the cold storage material, and a plurality of or one heat transfer pack is arranged so as to surround the food. ,
The cold storage material is placed on the opposite side of the food with the heat transfer pack in between.

According to the present invention, since the cold heat of the cold storage material is transferred to the food through the heat transfer pack, the food can be cooled in a supercooled state by the cold heat. In addition, heat transfer packs are constructed by filling the bag with a heat transfer liquid that is set at a freezing point that will not solidify due to the cold heat of the cold storage material, so the heat transfer liquid will solidify due to the cold heat of the cold storage material. It is possible to prevent this from happening. Further, since the heat transfer pack is arranged so as to surround the food, the vibration generated during delivery can be suppressed from being transmitted to the food due to the buffering effect of the heat transfer liquid. Therefore, it becomes possible to suitably maintain the supercooled state of the food. Therefore, from the above, it becomes possible to deliver food in a supercooled state without using a supercooling refrigerator.

Note that the term "food" includes not only cooked food but also ingredients before cooking.

A sectional view showing the inside of the food delivery set. A plan view showing the inside of the food delivery set. FIG. 1 is a diagram showing the configuration of a food delivery system.

An embodiment embodying the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing the inside of the food delivery set 10. As shown in FIG. FIG. 2 is a plan view showing the inside of the food delivery set 10.

The food delivery set 10 is for delivering food 16 in a supercooled state. As shown in FIGS. 1 and 2, the food delivery set 10 includes a delivery box 11, a food pack 12, a cold storage material 13, and a heat transfer pack 14 provided inside the delivery box 11. The delivery box 11 is a box shaped like a rectangular parallelepiped, and is made of styrofoam, for example. Note that, in FIG. 2, the delivery box 11 is shown with the lid 11a removed.

The food pack 12 includes food 16 packed in a vinyl bag 17. The food 16 is, for example, fresh food such as sashimi, fresh fish, and meat. The food 16 is packed into a bag 17 in a flat shape. Furthermore, the food 16 is packed in a bag 17 with sufficient air removed. Therefore, the food pack 12 has a flat shape as a whole.

The cold storage material 13 supplies cold heat to the food 16 in the food pack 12. The cold storage material 13 is formed by freezing a cold storage medium 19 filled in a vinyl bag 18. The cold storage material 13 has a rectangular flat shape. Moreover, in this embodiment, a liquid seasoning is used as the cold storage medium 19, and the liquid seasoning is in a frozen state. The liquid seasoning is, for example, noodle soup. The temperature of the cold storage material 13 is set to 0°C or lower, more specifically in the range of -20°C to -60°C. In this case, the temperature of the cold storage material 13 is such that the food 16 can be cooled in a supercooled state.

The heat transfer pack 14 transmits the cold heat of the cold storage material 13 to the food 16 in the food pack 12. The heat transfer pack 14 is constructed by filling a bag 21 with a heat transfer liquid 22 . The heat transfer pack 14 has a flat rectangular shape, and its size in plan view is approximately the same as the size of the cold storage material 13 in plan view.

The bag 21 of the heat transfer pack 14 is made of a flexible and pliable material, such as vinyl. Further, as the heat transfer liquid 22, soup is used. The soup is, for example, miso soup. Since the heat transfer liquid 22 (miso soup) contains salt and the like, the freezing point is lowered, and the freezing point is lower than the freezing point of water (that is, 0° C.). In this case, the freezing point of the heat transfer liquid 22 is such that it does not solidify due to the cold heat of the cold storage material 13 . The freezing point of the heat transfer liquid 22 is preferably -10°C or lower, more preferably -20°C or lower, and even more preferably -30°C or lower. Further, the freezing point of the heat transfer liquid 22 is preferably lower than the temperature of the cold storage material 13.

Next, the arrangement of the food pack 12, cold storage material 13, and heat transfer pack 14 contained in the delivery box 11 will be explained.

The food pack 12, the cold storage material 13, and the heat transfer pack 14 are all housed in the delivery box 11 with their thickness directions facing up and down. A cold storage material 13 is placed at the bottom of the delivery box 11, a heat transfer pack 14 is placed on top of the cool storage material 13, and a food pack 12 is placed on top of the heat transfer pack 14. Further, a heat transfer pack 14 is placed on top of the food pack 12, and a cold storage material 13 is placed on top of the heat transfer pack 14. Therefore, inside the delivery box 11, the food pack 12, the cold storage material 13, and the heat transfer pack 14 are stacked vertically, making a total of five layers.

The size of the food pack 12 in plan view is smaller than the size of the inside of the delivery box 11 in plan view. The food pack 12 is arranged so as to be located at the center of the delivery box 11 in plan view. Therefore, the entire peripheral edge of the food pack 12 is spaced apart from the inner surface of the delivery box 11. Note that the dimensions of the food pack 12 (food 16) are 5% or more smaller (10% or more smaller) than the inner dimensions of the delivery box 11 in each of the longitudinal and lateral directions of the delivery box 11 in plan view. (It is desirable that the
Heat transfer packs 14 are arranged on both upper and lower sides of the food pack 12, respectively. The lower heat transfer pack 14 (hereinafter referred to as "14A" in some cases) and the upper heat transfer pack 14 (hereinafter referred to as "14B" in some cases) are arranged side by side in plurality (for example, two) adjacent to each other. It is arranged as follows. Adjacent heat transfer packs 14A, 14B are in contact with each other. Both of these heat transfer packs 14A and 14B are placed in close contact with the food pack 12, more specifically, in close contact with the food 16 via the bag 17 of the food pack 12.

The peripheral edge side of each heat transfer pack 14A, 14B protrudes from the food pack 12 to form a protruding portion 24. The protruding portions 24 of each heat transfer pack 14A and the protruding portions 24 of each heat transfer pack 14B are in contact with each other on the peripheral edge side of the food pack 12. Specifically, the protruding portion 24 of each heat transfer pack 14A and the protruding portion 24 of each heat transfer pack 14B are in contact with each other on the peripheral edge side of the food pack 12. It is in contact. As a result, the entire food pack 12 is surrounded by each heat transfer pack 14A and each heat transfer pack 14B, and in turn, the entire food 16 is surrounded.

Cold storage materials 13 are arranged on both sides of the heat transfer packs 14A and 14B (and food packs 12), respectively. The lower cold storage material 13 (hereinafter referred to as "13A" in some cases) and the upper cold storage material 13 (hereinafter referred to as "13B" in some cases) are arranged side by side in plurality (for example, two) adjacent to each other. It is located. Adjacent cold storage materials 13A and 13B are in contact with each other. The lower cold storage material 13A is placed in close contact with the heat transfer pack 14A, and the upper cold storage material 13B is placed in close contact with the heat transfer pack 14B. Moreover, each cold storage material 13A is arranged so as to cover the entire lower surface of each heat transfer pack 14A, and each cool storage material 13B is arranged so as to cover the entire upper surface of each heat transfer pack 14B. In addition, in this embodiment, the cool storage material 13 and the heat transfer pack 14 which are vertically adjacent to each other are arranged in a one-to-one relationship.

According to the above-mentioned structure, each cold storage material 13 is arranged on the opposite side of the food pack 12 (food 16) with the heat transfer pack 14 in between. In this case, the cold heat of the cold storage material 13 is transferred to the food 16 in the food pack 12 via the heat transfer pack 14. Thereby, it becomes possible to cool the food 16 in a supercooled state by the cold heat of the cold storage material 13. Further, in this case, the food 16 is cooled by the cold storage material 13 so that the temperature of the food 16 is in the range of -3° C. to 0° C., thereby maintaining the food 16 in a supercooled state.

Inside the delivery box 11, a sheet material 25 is provided that collectively wraps the food pack 12, each heat transfer pack 14A, 14B, and each cold storage material 13A, 13B. The sheet material 25 is made of a flexible and pliable material, for example, a cushion sheet (air cap sheet) made of polyethylene. Therefore, the sheet material 25 has cushioning properties and heat insulation properties. Further, the sheet material 25 is preferably fixed using tape or the like so that the food pack 12, each heat transfer pack 14A, 14B, and each cold storage material 13A, 13B are kept wrapped by the sheet material 25. desirable. Note that in FIG. 1, the sheet material 25 is shown by dotted lines for convenience, and in FIG. 2, illustration of the sheet material 25 is omitted.

Next, a food delivery system using the above-mentioned food delivery set 10 will be explained based on FIG. 3. FIG. 3 is a diagram showing the configuration of the food delivery system.

The food delivery system is a system for delivering food 16 to a delivery destination using food delivery set 10, and is managed by a business that delivers food 16 (for example, a vendor of food 16). As shown in FIG. 3, the food delivery system includes a management server 30 installed at a business office of a vendor, and a terminal device 32 installed at a packing place 31 where food 16 is packed. The management server 30 and the terminal device 32 are configured by, for example, a personal computer. Further, the management server 30 and the terminal device 32 are communicably connected via a network 34. Furthermore, the management server 30 is also communicably connected to the customer terminal 35 of each customer via the network 34. The customer terminal 35 is constituted by a portable terminal such as a personal computer or a smartphone, for example. Note that the management server 30 corresponds to a processing device.

The management server 30 has a reception section 37 that receives orders and delivery destinations for the food products 16 from customers. The reception section 37 has a reception screen that can be accessed by the customer terminal 35. The customer can access the reception screen and order the food 16 and give instructions on the delivery destination on the reception screen. As a result, the reception unit 37 receives the order and delivery address for the food product 16.

The management server 30 further includes, when the reception unit 37 receives an order for the food 16, a determination unit 38 that determines the amount and temperature of the cold storage material 13 to be accommodated in the delivery box 11 based on the delivery destination of the received food 16. have. The determining unit 38 calculates the estimated delivery period from the packing place 31 to the delivery destination, and determines the amount and temperature of the cold storage material 13 based on the calculated estimated delivery period. Specifically, when the distance from the packing place 31 to the delivery destination is long, the determining unit 38 estimates a long period as the estimated delivery period, and increases the amount of cold storage material 13 based on the estimated delivery period. or to lower the temperature of the cold storage material 13.

Note that the determining unit 38 may determine only one of the amount and temperature of the cold storage material 13.

When the reception unit 37 receives an order for the food 16, the management server 30 transmits packing instruction information regarding the packing instruction for the food 16 to the terminal device 32 at the packing location 31. This packing instruction information includes information on the amount and temperature of the cold storage material 13 determined by the determination unit 38, respectively. When the packing instruction information is received by the terminal device 32, the terminal device 32 displays the received packing instruction information on the display. Thereby, the packing worker at the packing place 31 performs the task of storing and packing the food 16 in the delivery box 11 together with the heat transfer pack 14 and the cold storage material 13 based on the displayed packing instruction information. Further, during this packing work, the packing worker stores the cold storage material 13 in the amount and temperature specified on the display into the delivery box 11. As a result, the food delivery set 10 is formed, and preparation for delivery of the food 16 is completed. Note that the amount of cold storage material 13 may be adjusted by adjusting the number of cold storage materials 13 or by adjusting the amount of cold storage medium 19 filled into bag 18.

Thereafter, the food delivery set 10 is delivered to the delivery destination by a delivery company. Note that the food delivery set 10 may be delivered by a normal refrigerated delivery service (cooling temperature during transportation is 0 to 10°C) or by a normal temperature delivery service.

According to the configuration of this embodiment described in detail above, the following excellent effects can be obtained.

As described above, since the cold heat of the cold storage material 13 is transferred to the food 16 in the food pack 12 via the heat transfer pack 14, the food 16 can be cooled in a supercooled state by the cold heat. Furthermore, since the freezing point of the heat transfer liquid 22 of the heat transfer pack 14 is set at a temperature at which it will not solidify due to the cold heat of the cold storage material 13, the heat transfer liquid 22 is prevented from solidifying due to the cold heat of the cold storage material 13. can do. Moreover, since each heat transfer pack 14 is arranged so as to surround the food 16, the vibration generated during delivery can be suppressed from being transmitted to the food 16 due to the buffering effect of the heat transfer liquid 22. Therefore, it becomes possible to suitably maintain the supercooled state of the food 16. Therefore, from the above, it becomes possible to deliver the food 16 in a supercooled state without using a supercooling refrigerator.

The heat transfer liquid 22 of the heat transfer pack 14 is miso soup. In this case, when the miso soup is delivered together with the food 16, the miso soup can be conveniently used as the heat transfer liquid 22.

The cold storage medium 19 of the cold storage material 13 is noodle soup as a liquid seasoning. In this case, when the noodle soup is delivered together with the food 16, the cold storage material 13 can be formed using the noodle soup, which is convenient.

Heat transfer packs 14A and 14B are arranged on both sides of the food 16 above and below, respectively, and the protruding portions 24 of the heat transfer packs 14A and 14B on both sides are in contact with each other on the peripheral edge side of the food 16 (food pack 12). In this case, the heat transfer pack 14 can be relatively easily placed surrounding the food 16. In addition, the cold storage materials 13 are arranged on both sides of the heat transfer packs 14A, 14B on both sides in the direction in which the heat transfer packs 14A, 14B are arranged (that is, in the vertical direction). In this case, since cold heat is transmitted from each of the cold storage materials 13 to the food 16 via the heat transfer pack 14, it is possible to suitably maintain the food 16 in a supercooled state.

Food 16, heat transfer pack 14, and cold storage material 13 are wrapped together by sheet material 25. In this case, the food 16 and the heat transfer pack 14 can be easily brought into close contact with each other, and the heat transfer pack 14 and the cold storage material 13 can be easily brought into close contact with each other. Therefore, the cold heat of the cold storage material 13 can be easily transferred to the food 16 via the heat transfer pack 14. Further, since the heat transfer pack 14 includes the heat transfer liquid 22, its shape is easily changed. In this respect, according to the above configuration using the sheet material 25, it is easy to maintain the state in which the food 16 is surrounded by the heat transfer pack 14, and the transmission of vibrations to the food 16 can be reliably suppressed. Therefore, in this case, it becomes possible to maintain the supercooled state of the food 16 suitably.

The food 16 (food pack 12), the heat transfer pack 14, and the cold storage material 13 are all in a flat shape, and are stacked in a stacked manner with their thickness directions facing up and down. In this case, the stability of the stacked state can be ensured, and the cold heat of the cold storage material 13 can be easily transmitted to the food 16 through the heat transfer pack 14.

The management server 30 of the food delivery system includes a reception unit 37 that receives orders and delivery destinations for the food 16, and a determination unit 38 that determines the amount and temperature of the cold storage material 13 based on the delivery destination received by the reception unit 37. are doing. When the order for the food 16 is accepted by the reception unit 37, the food 16 is housed in the delivery box 11 together with the cold storage material 13 and the heat transfer pack 14 and packed at the packing location 31. As a result, the food delivery set 10 is formed, and preparation for delivery in a supercooled state is completed. Further, the determining unit 38 determines the amount and temperature of the cold storage material 13 to be accommodated in the delivery box 11 based on the estimated delivery period from the packing place 31 to the delivery destination. Thereby, the amount and temperature of the cold storage material 13 depending on the delivery destination can be stored in the delivery box 11, so that the food 16 can be suitably delivered in a supercooled state regardless of the delivery destination.

The present invention is not limited to the above embodiments, and may be implemented, for example, as follows.

- In the above embodiment, liquid seasoning is used as the cold storage medium 19 of the cold storage material 13, but soups such as miso soup and vegetable soup, or beverages such as juice and water may be used as the cold storage medium 19.

In short, the number of cold storage materials 13A and 13B may be appropriately set to a number that can maintain the food 16 in a supercooled state, depending on the estimated delivery period and the like. Further, as long as the food 16 can be maintained in a supercooled state, only one of the lower cold storage material 13A and the upper cold storage material 13B may be provided.

- In the above embodiment, miso soup is used as the heat transfer liquid 22 of the heat transfer pack 14, but soups other than miso soup, such as vegetable soup or corn soup, may be used. Further, as the heat transfer liquid 22, liquid seasoning such as noodle soup or soy sauce, or a beverage such as juice may be used. However, even when using these liquid seasonings and drinks as the heat transfer liquid 22, it is necessary to use liquids whose freezing point is set at a temperature at which they will not solidify due to the cold heat of the cold storage material 13. Further, as the heat transfer liquid 22, it is not necessarily necessary to use a liquid for drinking or drinking such as liquid seasoning, juice, or beverage, and a liquid exclusively for heat transfer such as a cold storage liquid may be used.

- It is not always necessary to arrange two lower heat transfer packs 14A and upper heat transfer packs 14B, and they may be arranged three or more, or one each. Further, the lower heat transfer packs 14A and the upper heat transfer packs 14B do not necessarily need to be the same number, and may be different numbers. In short, the number of heat transfer packs 14 may be arbitrary as long as a plurality of heat transfer packs 14 are arranged so as to surround the food pack 12 (food 16).

Alternatively, the number of heat transfer packs 14 may be one, and the one heat transfer pack 14 may be arranged so as to surround the food pack 12. In this case, for example, the heat transfer pack 14 may be formed into an elongated shape, and the elongated heat transfer pack 14 may be arranged in a folded state so as to sandwich the food pack 12 therebetween.
