[0010] The shoulder bag of the present invention will be described with reference to the embodiment shown in the drawings. In this embodiment, the up-down direction in Fig. 1 is the up-down direction, the left-right direction is the width direction, and the left-right direction in Fig. 2 and Fig. 3 is the front-rear direction. 1 to 3, the shoulder bag 1 of the present invention has a bag body 10 and a shoulder belt 50 attached to the bag body 10. The bag body 10 includes a front part 11 made of a heat insulating material, a back part 12 facing the front part 11 and also made of a heat insulating material, (a pair of opposing side parts 13), an upper opening 14 formed between the front part 11 and the back part 12 at the top of the bag body 10, and a main storage part 15 formed between the front part 11 and the back part 12 and communicating with the outside at the upper opening 14. The main storage section 15 is provided with an insulating partition 16 formed from an insulating material on one of the rear section 12 side or the front section 11 side (here, the rear section 12 side) of the main storage section 15, an insulating storage section 17 formed between the insulating partition 16 and the rear section 12 or the front section 11 (here, the rear section 12) on the side on which the insulating partition 16 is provided, a thermally permeable partition 18 provided on the other of the rear section 12 side or the front section 11 side (here, the front section 11 side) of the main storage section 15 and formed from a member (here, a mesh member 29) having a higher thermal conductivity than the insulating partition 16, and a thermally permeable storage section 19 formed between the thermally permeable partition 18 and the rear section 12 or the front section 11 (here, the front section 11) on the side on which the thermally permeable partition 18 is provided. The shoulder bag further includes a sub-storage section 20 provided on the front side of the front section 11 (the side opposite to the main storage section 15) and thermally isolated from the main storage section 15 by the front section 11.

[0011] More specifically, the bag body 10 of this embodiment includes a front portion forming member 21, a back portion forming member 22, and a bottom portion forming member 23, which are made of known heat insulating sheet members, and are sewn together at their adjacent peripheral edges. Note that the method of joining the members together is not limited to sewing, and various known methods (such as adhesion and heat fusion) can also be used, and the same applies hereinafter in this specification.

[0012] As the heat insulating sheet members (front surface forming member 21, back surface forming member 22, bottom surface forming member 23) constituting the bag body 10, various known sheet members having heat insulating properties can be used, and in this embodiment, each heat insulating sheet member is provided with a heat insulating material (heat insulating layer) almost entirely. Examples of such heat insulating sheet members include a multi-layered sheet member in which a foam sheet is laminated on an aluminum foil or an aluminum deposition film, a sheet member in which a heat insulating material such as a foam sheet or an aluminum laminate film is laminated on the inside of a synthetic resin fiber cloth forming an outer layer, and a sheet member in which a heat insulating material is filled inside a synthetic resin fiber cloth forming an outer layer to improve heat insulating properties. Examples of heat insulating materials used in such heat insulating sheet members include glass wool, slug wool, roll wool, synthetic resin fibers (e.g., polyester resin fibers, etc.), foam sheets (e.g., polyethylene foam sheets, polyurethane foam sheets, sponge sheets), rubber or elastomers (silicone rubber, polyolefin elastomers), etc. In addition, each of the insulating sheet components (front portion forming component 21, back portion forming component 22, bottom portion forming component 23) preferably has an outer layer made of cloth with excellent designability that forms the outer surface of the bag main body 10.

[0013] In this embodiment, the bottom portion forming member 23 is rectangular (approximately rectangular), and the bottom portion 24 of the bag body 10 is formed by such bottom portion forming member 23. A first side portion (here, the peripheral edge portion on the front side) of the bottom portion forming member 23 is joined (sewn) to the lower end edge portion (the lower end of the front portion 11) of the front portion forming member 21, and a second side portion (here, the peripheral edge portion on the back side) of the bottom portion forming member 23 facing such first side portion is joined (sewn) to the lower end edge portion of the back portion forming member 22 (the lower end of the back portion 12).

[0014] The bag body 10 includes a front portion 11 and a back portion 12 opposed to the front portion 11. In this embodiment, the bag body 10 has a generally rectangular shape (the vertical dimension is greater than the width dimension) when viewed from the front (and from the back (not shown)) as shown in FIG. 1. That is, the bag body 10 includes the front portion 11 and the back portion 12, each of which has a generally rectangular shape. In other words, the front portion 11 is formed by a generally rectangular portion of the front portion forming member 21 that can be seen in a front view, and the back portion 12 is formed by a generally rectangular portion of the back portion forming member 22 that can be seen in a back view.

[0015] As shown in Fig. 2, the bag body 10 has a pair of side portions 13, 13 (only one (the left side) is shown in Fig. 2) that are substantially triangular in side view. In this embodiment, a front portion forming member 21 and a back portion forming member 22 are sewn together at a formation site of the side portion 13, and each side portion 13, 13 is formed by a part of the front portion forming member 21 (front portion 11 non-forming portion) and a part of the back portion forming member 22 (back portion 12 non-forming portion).

[0016] Although not described in detail, in this embodiment, as shown in Fig. 1, both ends of the shoulder belt 50 are attached to the side portions 13, 13 of the bag body 10. The shoulder belt may be attached directly to the bag body, or may be attached using a known attachment member, and may be equipped with a known length adjustment mechanism.

[0017] A main storage section 15 is formed inside the bag body section 10. Specifically, as shown in Fig. 3, inside the bag body section 10, the space surrounded by the front section 11, the back section 12, the bottom section 24, and the pair of side sections 13 forms the main storage section 15. In this embodiment, the main storage section 15 is an insulated space surrounded almost entirely by a thermal insulating material, and the main storage section 15 exhibits a cold or warm insulation function.

[0018] An upper opening 14 is formed at the top of the bag body 10 between the front portion 11 (front portion forming member 21) and the back portion 12 (back portion forming member 22). The bag body 10 is configured so that its interior (main storage portion 15) can communicate with the outside at the upper opening 14. In other words, items 41, 42, 43 can be put in and taken out of the main storage portion 15 through the upper opening 14.

[0019] In this embodiment, the upper opening 14 is provided with a first fastener portion 25 having a fastener fitting 26, and the upper opening 14 can be opened and closed by the fastener mechanism of the first fastener portion 25. Note that the upper opening is not limited to being openable and closable by a fastener mechanism, and may be openable and closable by, for example, a fastener such as a button.

[0020] As shown in FIG. 3, the main storage section 15 of this embodiment includes a heat insulating partition 16 formed of a heat insulating material and provided on the rear section 12 side of the main storage section 15. Specifically, the heat insulating partition 16 of this embodiment is made of a known heat insulating sheet member, and the peripheral portion except for the upper edge portion is joined (sewn) to the above-mentioned rear section forming member 22. The heat insulating partition is not limited to being joined (integrated) to the rear section by sewing or the like, and may be provided on the rear section side from the center of the main storage section so as to ensure a storage space of the main storage section (a storage space formed between the heat insulating partition and a heat transmitting partition described later). The heat insulating sheet member constituting the above-mentioned bag body section 10 can be used as the known heat insulating sheet member constituting the heat insulating partition 16. It is preferable that the heat insulating partition 16 is water impermeable.

[0021] In the main storage section 15, a heat-insulating storage section 17 is formed between the back section 12 and the heat-insulating partition section 16. An upper opening 27 of the heat-insulating storage section is formed between the back section 12 and the upper edge of the heat-insulating partition section 16 (a portion not sewn to the back section 12), and an article 42 can be put in and taken out of the heat-insulating storage section 17 through the upper opening 27 of the heat-insulating storage section.

[0022] In the main storage section 15, the provision of the heat insulating partition 16 prevents direct thermal contact between the item 42 stored in the heat insulating storage section 17 and the item 41 stored in the main storage section 15 (the storage space formed between the heat insulating partition 16 and the heat transmitting partition 18). This prevents, for example, deterioration or damage to the wallet itself, or to magnetic cards stored in the wallet or IC chips attached to the cards, when a wallet is stored as the item 42 in the heat insulating storage section 17.

[0023] In addition, in the shoulder bag 1 of this embodiment, since the insulating storage section 17 is provided on the back portion 12 side of the main storage section 15 (the side facing the user when in use), heat from items 41 (plastic bottles, etc.) stored in the main storage section 15 (storage space formed between the insulating partition section 16 and the thermally conductive partition section 18) and items 43 (ice packs, hand warmers, etc.) stored in the thermally conductive storage section 19 described below is not easily transferred to the user, and the shoulder bag 1 can be used comfortably.

[0024] The upper end of the heat insulating partition 16 is preferably located above the upper end of the heat conductive partition 18 described below. In other words, the heat insulating storage section upper opening 27 is preferably provided above the heat conductive storage section upper opening 28 described below. This makes it possible to further prevent deterioration and damage of the items 42 (wallets, etc.) stored in the heat insulating storage section 17 due to the influence of heat from the items 43 (ice packs, pocket warmers, etc.) stored in the heat conductive storage section 19.

[0025] 3, the main storage section 15 of this embodiment includes a heat-transmitting partition section 18 provided on the front section 11 side of the main storage section 15 and formed of a member (here, a mesh member 29) having a higher heat transmission than the heat-insulating partition section 16. Specifically, the mesh member 29 constituting the heat-transmitting partition section 18 of this embodiment is a mesh member (mesh pocket) formed in a bag shape made of synthetic resin fiber. More specifically, the mesh member (mesh pocket) 29 of this embodiment has an upper edge portion sewn to the front section 11 (front section forming member 21), and the heat-transmitting partition section 18 is constituted by a portion of the mesh member (mesh pocket) 29 on the back section side.

[0026] The material constituting the heat-transmitting partition is not limited to the exemplified mesh material (mesh pocket) and may be a relatively thin sheet material made of synthetic resin fiber. The heat-transmitting partition is not limited to the above-mentioned embodiment and may be formed by sewing a sheet-like mesh material to the front part, for example. The heat-transmitting partition is not limited to being integrated with the front part by sewing or the like, and is preferably provided closer to the front part than the center of the main storage part so as to ensure storage space for the main storage part (storage space formed between the heat-insulating partition and the heat-transmitting partition).

[0027] In the main storage section 15, a heat-transmitting storage section 19 is formed between the front section 11 and the heat-transmitting partition section 18. In this embodiment, the inside of a mesh member (mesh pocket) 29 constitutes the heat-transmitting storage section 19. Note that a heat-transmitting storage section upper opening 28 is formed in the upper part of the mesh member (mesh pocket) 29, and an article 43 can be put in and taken out of the heat-transmitting storage section 19 through the heat-transmitting storage section upper opening 28.

[0028] In the main storage section 15, the heat-transmitting partition 18 is provided, so that heat exchange between the item 43 stored in the heat-transmitting storage section 19 and the item 41 stored in the main storage section 15 (the storage space formed between the heat-insulating partition 16 and the heat-transmitting partition 18) is not easily hindered. As a result, when an ice pack or the like is stored as the item 43 in the heat-transmitting storage section 19, the item 41 (a plastic bottle drink, a neck ring, etc.) stored in the main storage section 15 can be effectively kept cold or cooled. Note that a hand warmer or the like can be stored as the item 43 in the heat-transmitting storage section 19, and the item 41 stored in the main storage section 15 can be effectively kept warm or heated.

[0029] Furthermore, the shoulder bag 1 of this embodiment includes a sub-storage section 20 that is provided on the front side of the front portion 11 (the side opposite to the main storage section 15) and is thermally isolated from the main storage section 15 by the front portion 11. Specifically, in this embodiment, a sub-storage section forming member 30 made of a cloth member made of synthetic resin fiber is sewn to the front portion 11 (front portion forming member 21) at its peripheral portion excluding its upper edge portion, and the sub-storage section 20 is formed between the front portion 11 (front portion forming member 21) and the sub-storage section forming member 30. As a result, the shoulder bag 1 has a cold or heat retention function in the main storage section 15, while allowing items 44 (e.g., a smartphone, a mobile battery, etc.) that should not be affected by the heat caused by such a cold or heat retention function to be separately stored in the sub-storage section 20.

[0030] In addition, at the upper part of such sub-storage section 20 (below the upper opening 14 of the bag main body section 10 described above), a sub-storage section upper opening 31 is provided which connects the inside of the sub-storage section 20 with the outside, and items 44 can be put in and taken out of the sub-storage section 20 via the sub-storage section upper opening 31.

[0031] In this embodiment, the sub-storage upper opening 31 is provided with a second fastener portion 32 equipped with a fastener fitting 33, and the sub-storage upper opening 31 can be opened and closed by the fastener mechanism of the second fastener portion 32. Note that the sub-storage upper opening is not limited to being openable and closable by a fastener mechanism, and may be openable and closable by, for example, a fastener such as a button.

[0032] The sub-storage section forming member 30 (the surface of the sub-storage section 20 on the opposite side to the main storage section 15) is preferably formed from a material having a higher thermal conductivity than the front section 11 (here, a cloth material made of synthetic resin fiber that does not include the above-mentioned heat insulating material (insulating layer)). This keeps the inside of the sub-storage section 20 closer to the outside environment (temperature, etc.) than the environment (temperature, etc.) inside the main storage section 15, and reduces the change in the environment when the item 44 is put in or taken out of the shoulder bag 1 (sub-storage section 20), thereby suppressing deterioration or damage to the item 44 stored in the sub-storage section 20. This effect is particularly effective when electronic devices such as smartphones and mobile batteries are stored in the sub-storage section 20 as the item 44.

[0033] In addition, it is preferable that the inside of the sub-storage section 20 cannot be seen from the outside. In other words, in this embodiment, it is preferable that the sub-storage section forming member 30 constituting the sub-storage section 20 is a material that does not transmit or does not easily transmit visible light. This can improve crime prevention, particularly when storing relatively expensive electronic devices such as smartphones and mobile batteries as the items 44 in the sub-storage section 20.

[0034] In addition, the above-mentioned storage spaces, i.e., the storage space (storage space for item 41) formed between the heat insulating partition 16 and the heat transmitting partition 18 in the main storage section 15, the storage space (storage space for item 42) in the heat insulating storage section 17, and the storage space (storage space for item 43) in the heat transmitting storage section 19, are preferably smaller in the listed order. In other words, the storage space (storage space for item 41) formed between the heat insulating partition 16 and the heat transmitting partition 18 in the main storage section 15 is preferably larger than the storage space (storage space for item 42) in the heat insulating storage section 17, and the storage space (storage space for item 42) in the heat insulating storage section 17 is preferably larger than the storage space (storage space for item 43) in the heat transmitting storage section 19. In addition, the storage space (storage space for item 44) in the sub storage section 20 is smaller than the storage space in the main storage section 15.

[0035] The shoulder bag of the present invention may be a shoulder bag 1a as shown in Fig. 4. In this embodiment, the main storage section 15a of the bag body 10a of the shoulder bag 1a has a heat-insulating partition 16a provided on the front section 11 side of the main storage section 15a, and a heat-insulating storage section 17a is formed between the front section 11 and the heat-insulating partition 16a in the main storage section 15a. The main storage section 15a also has a heat-transmitting partition 18a (mesh member 29) provided on the back section 12 side of the main storage section 15a, and a heat-transmitting storage section 19a is formed between the back section 12 and the heat-transmitting partition 18a in the main storage section 15a.

[0036] Even in such a shoulder bag 1a, a sub-storage section 20 is provided on the front side of the front portion 11 (the opposite side from the main storage section 15a) and is thermally isolated from the main storage section 15a by the front portion 11. Therefore, while the main storage section 15a has a cold or heat retention function, items 44 (e.g., a smartphone, mobile battery, etc.) that should not be affected by the heat caused by such a cold or heat retention function can be stored separately in the sub-storage section 20.

[0037] Furthermore, in main storage section 15a, heat insulating partition 16a prevents direct thermal contact between item 42 stored in heat insulating storage section 17a and item 41 stored in main storage section 15a (storage space formed between heat insulating partition 16a and heat transmitting partition 18a). This prevents, for example, deterioration or damage to the wallet itself, magnetic cards stored in the wallet, or IC chips attached to the cards when a wallet is stored as item 42 in heat insulating storage section 17a.

[0038] In addition, in the main storage section 15a, the heat-transmitting partition 18a makes it difficult for heat exchange to be impeded between the item 43 stored in the heat-transmitting storage section 19a and the item 41 stored in the main storage section 15a (the storage space formed between the heat-insulating partition 16a and the heat-transmitting partition 18a). As a result, for example, when a cooling agent or the like is stored as the item 43 in the heat-transmitting storage section 19a, the item 41 (a plastic bottle drink, a neck ring, or the like) stored in the main storage section 15a can be effectively kept cold or cooled. Note that a hand warmer or the like can also be stored as the item 43 in the heat-transmitting storage section 19a to effectively keep warm or heat the item 41 stored in the main storage section 15a.

[0039] The shoulder bag of the present invention may be a shoulder bag 1b as shown in Fig. 5. In the main storage section 15b of the bag body section 10b of the shoulder bag 1b of this embodiment, a second insulating partition section 16b is formed on the back surface section 12 side of the insulating partition section 16, and a second insulating storage section 17b is formed adjacent to the insulating storage section (first insulating storage section) 17. A second insulating storage section upper opening 27b is formed on the upper part of the second insulating storage section 17b, and items can be put in and taken out of the second insulating storage section 17b through the second insulating storage section upper opening 27b. In such a shoulder bag 1b, items can be stored in the main storage section 15b after being separated into smaller items, and items 42 stored in the insulated storage section 17 can be more thermally isolated from items 41 stored in the main storage section 15 (the storage space formed between the insulated partition section 16 and the thermally conductive partition section 18). For example, when a wallet or the like is stored as item 42 in the insulated storage section 17, deterioration or damage to the wallet itself, or to magnetic cards stored in the wallet or IC chips attached to the cards can be more effectively prevented.
