Description

[Technical Field]

[0001] The present invention relates to a container package for packaging a bottomed, top-opening container having a flange on its outer periphery, which contains food. [Background technology]

[0002] There is a cardboard storage box (see, for example, storage box 1 in FIG. 1 of Patent Document 1) that stores bottomed, top-opening containers with flanges on the outer periphery, containing fruit or the like, in a state where the containers are floating above the bottom plate.

[0003] The storage box 1 of Patent Document 1 is formed by assembling a main body (Fig. 3 of Patent Document 1) and partition plates (Fig. 5 of Patent Document 1) with a complex unfolded shape, and then assembling them together (Fig. 1 of Patent Document 1). With the eave portion Aa of the object A supported from below by the support portions 9, 19 of the storage box 1, a space is formed between the bottom surface of the object A and the bottom plate 2 of the storage box 1 (Fig. 2 of Patent Document 1).

[0004] On the other hand, there is a storage container made of synthetic resin that stores fruit or the like in a suspended state (see, for example, a suspended article storage container 10A' in Patent Document 2).

[0005] The storage container 10A' of Patent Document 2 has a thin, flexible storage film 1A having storage recesses 2 for individually storing fruit or the like, supported by a bottomed, top-opening container 10A having a flange on its outer periphery (Fig. 5 of Patent Document 2). With the storage film 1A supported by the bottomed, top-opening container 10A of the storage container 10A', a space S is formed between the bottom of the storage recesses 2 and the bottom surface 14 of the bottomed, top-opening container 10A (Fig. 5(b) of Patent Document 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 5837540 [Patent Document 2] Patent No. 6637018 Summary of the Invention [Problem to be solved by the invention]

[0007] When a bottomed, top-opening container with a flange on the outer periphery containing food is transported by truck or the like in the storage box 1 of Patent Document 1, there is a space between the bottom of the container and the bottom plate 2 of the storage box 1, and the downward movement of the container supported from below by supports 9, 19 is restricted by the supports 9, 19. Therefore, the bottom of the container will not hit the bottom plate 2 due to transport vibrations such as those caused by truck transport, and the food will not be damaged.

[0008] However, the transport vibrations cause the containers to move up and down above the support parts 9, 19. Therefore, the transport vibrations may cause the containers and food to move upward away from the support parts 9, 19, potentially damaging the food.

[0009] When transporting storage container 10A' of Patent Document 2 containing food, multiple storage containers 10A' are placed in, for example, a cardboard box with a lid for transport. In storage container 10A' of Patent Document 2, a space S is formed between the bottom of storage recess 2 and bottom surface 14 of bottomed, top-opening container 10A. Therefore, the bottom of storage recess 2 will not hit bottom surface 14 of container 10A due to transport vibrations such as those caused by truck transport, which will damage the food.

[0010] However, the storage container 10A' placed in a cardboard box with a lid or the like moves up and down in the cardboard box or the like due to the vibrations during transportation, which may cause the container and food to move upward and damage the food.

[0011] It is also known that when food is exported overseas, it is handled very roughly depending on the country of export. When handling containers containing food overseas, for example, when loading the containers onto the back of a truck, the containers may be thrown or handled with excessive force, which may result in the containers being turned upside down or subjected to a large impact.

[0012] In other words, when a bottomed, top-opening container having a flange on the outer periphery and filled with food is transported by air or truck in the storage box 1 of Patent Document 1, or when a storage container 10A' of Patent Document 2 containing food is placed in a cardboard box with a lid and transported by air or truck, there is a risk that the food will be damaged due to severe transport vibrations or rough handling.

[0013] The present invention aims to prevent damage to food not only from vibrations during transport such as air transport or truck transport, but also from rough handling in a container packaging device for packaging a bottomed, top-opening container having a flange on the outer periphery and containing food. [Means for solving the problem]

[0016] A container packaging device according to a third aspect of the present invention is the container packaging device according to the second aspect, wherein the left concave strip is between an upper convex strip and a lower convex strip provided at the top and bottom of the inner surface of a middle portion in the vertical direction of the left side surface member, or a left recessed portion formed by deforming a middle portion in the vertical direction of the left side surface member to the left. The right concave strip is between an upper convex strip and a lower convex strip provided at the top and bottom of the inner surface of a middle portion in the vertical direction of the right side surface member, or a right recessed portion formed by deforming a middle portion in the vertical direction of the right side surface member to the right.

[0017] A container packaging device according to a fourth aspect of the present invention is the container packaging device according to the third aspect, wherein the upper convex strip and the lower convex strip are made of an impact absorbing material.

[0018] A container packaging device according to a fifth aspect of the present invention is the container packaging device according to the first aspect, wherein the left side surface member has a left band plate material attached from the outside with a gap between the lower end of the upper left side surface member and the upper end of the lower left side surface member, a left recessed strip in the front-to-rear direction between the upper left side surface member and the lower left side surface member, and the left recessed strip serves as the flange support portion. The right side surface member has a right band plate material attached from the outside with a gap between the lower end of the upper right side surface member and the upper end of the lower right side surface member, and a right recessed strip in the front-to-rear direction between the upper right side surface member and the lower right side surface member, and the right recessed strip serves as the flange support portion. The top surface member, the bottom surface member, the upper left side surface member, the lower left side surface member, the upper right side surface member, and the lower right side surface member are cardboard sheets, and the left band plate material and the right band plate material are cardboard sheets, paperboard, or hard synthetic resin sheets.

[0019] A container packaging device according to a sixth aspect of the present invention is the container packaging device according to the first aspect, wherein the top surface material, the bottom surface material, the left surface material, and the right surface material are cardboard sheets. The left surface material consists of an upper left surface material and a lower left surface material separated into top and bottom, and the right surface material consists of an upper right surface material and a lower right surface material separated into top and bottom. The flange support portion is formed between the lower end of the upper left surface material and the upper end of the lower left surface material, and between the lower end of the upper right surface material and the upper end of the lower right surface material. The flange of the container containing food is placed on the upper end of the lower left surface material and the upper end of the lower right surface material, and the upper left surface material and upper right surface material are placed on the flanges, with the top surface material, bottom surface material, left surface material, and right surface material covered with a film material.

[0020] The food to be placed in the container is, for example, fruit or vegetable such as strawberries, peaches, or grapes, or baked goods such as cookies or tarts, or sweets such as chocolates. [Effects of the Invention]

[0021] According to the container packaging device of the present invention, when a bottomed, top-opening container containing food and having a flange on its outer periphery is stored within the container packaging device and the flange is supported by the left and right flange support portions, there is a first gap between the food and the top surface material of the container packaging device, and there is a second gap between the container and the bottom surface material of the container packaging device, and the flange support portions support the flange so that the first gap and the second gap remain even when the container packaging device is turned upside down.

[0022] Therefore, even if the container packaging device vibrates up and down due to vibrations during transport such as air transport or truck transport, the food will not collide with the top surface material of the container packaging device, and the container containing the food will not collide with the bottom surface material of the container packaging device, thereby preventing damage to the food stored in the container packaging device.

[0023] Also, since the flange is supported by the flange support portion such that the first gap and the second gap are present even when the container packaging is turned upside down, even if for some reason the container packaging is turned upside down and the container and the food are in an upside-down state and vibrate vertically, damage to the food stored in the container packaging can be suppressed.

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0026] 1-2. A container packaging device 1 according to an embodiment of the present invention is sleeve-shaped and has a first opening A1 at a first end E1 and a second opening A2 at a second end E2. In this embodiment, the direction from the first end E1 toward the second end E2, i.e., the direction from the first opening A1 toward the second opening A2, is referred to as the front (see arrow F in FIG. 1), and the opposite direction is referred to as the rear (see arrow B in FIG. 1), with a view from the rear being referred to as a front view. Furthermore, left (see arrow L in FIG. 2) and right (see arrow R in FIG. 2) are defined in terms of the forward direction.

[0027] The container packaging device 1 has flange support portions H on the left and right sides that support the flange V of a bottomed, top-opening container T having a flange V on its outer periphery, as shown in Figures 3-4. The bottomed, top-opening container T having a flange V on its outer periphery may have a storage recess U for storing food items individually, as shown in Figure 3, or may not have a storage recess U, as shown in Figure 4, or may be a suspended article storage container, as shown in Patent Document 2, or the like.

[0028] The container packaging device 1 shown in Fig. 1-2 comprises upper surface material 2 and lower surface material 3 which are rectangular in plan view, and left surface material 4 and right surface material 5 which are rectangular in side view. The left surface material 4 is connected to the left edge 2L of the upper surface material 2 and the left edge 3L of the lower surface material 3, and the right surface material 5 is connected to the right edge 2R of the upper surface material 2 and the right edge 3R of the lower surface material 3. The upper surface material 2, lower surface material 3, left surface material 4, and right surface material 5 are made of paperboard or hard synthetic resin sheets or the like, and are relatively thin.

[0029] In the example of Figure 1-2, the upper end of the left side panel 4 is bent to the right and bonded to the lower surface of the left end of the top panel 2 at joint surface I. As a result, the top panel 2, bottom panel 3, left panel 4, and right panel 5 are integrated into a sleeve shape.

[0030] The container packaging device 1 is provided with flange support parts H that support the flange V of a bottomed, top-opening container T at the vertical middle part of the left side panel 4 and the vertical middle part of the right side panel 5. Food S is placed in a bottomed, top-opening container T having a flange V on its outer periphery as shown in Figure 5, and the food S is covered on the top with cellophane film W. This container is then inserted into the container packaging 1 through the first opening A1 or the second opening A2 in Figure 1, and the left and right flanges V are supported by the left and right flange support parts H. Because the container packaging device 1 is sleeve-shaped, the container T containing the food S can be easily inserted into the container packaging device 1 through the first opening A1 or the second opening A2.

[0031] The flange support portion H is a left recessed strip CSL in the front-to-rear direction that is recessed to the left and provided on the inner surface of the middle part in the vertical direction of the left side surface member 4, and a right recessed strip CSR in the front-to-rear direction that is recessed to the right and provided on the inner surface of the middle part in the vertical direction of the right side surface member 5. The left recessed strip CSL is between the upper convex strip C1L and the lower convex strip C2L that are provided at the top and bottom of the inner surface of the middle part in the vertical direction of the left side surface member 4, and the right recessed strip CSR is between the upper convex strip C1R and the lower convex strip C2R that are provided at the top and bottom of the inner surface of the middle part in the vertical direction of the right side surface member 5.

[0032] The upper convex strip C1L, the lower convex strip C2L, the upper convex strip C1R, and the lower convex strip C2R are rod-shaped and long in the front-to-rear direction, and have a required cross-sectional shape such as a rounded (semi-cylindrical) cross section as shown in Figure 2, or a mountain-shaped cross section. The upper convex strip C1L and the lower convex strip C2L are bonded to the inner surface of the left side surface member 4 (the right surface of the left side surface member 4 in Figure 2), and the upper convex strip C1R and the lower convex strip C2R are bonded to the inner surface of the right side surface member 5 (the left surface of the right side surface member 5 in Figure 2).

[0033] The convex strips C1L, C2L, C1R, and C2R are preferably shock absorbing materials, and in a preferred embodiment, they are made of foamed synthetic resins such as foamed polyethylene, foamed acrylic, or foamed silicone, or thermosetting resin elastomers such as urethane rubber, silicone rubber, or fluororubber, or thermoplastic elastomers.

[0034] By using shock-absorbing materials for the convex strips C1L, C2L, C1R, and C2R that form the left and right flange support portions H, it is possible to reduce vibrations that are transmitted to the food inside the container T via the flange V of the container T when, for example, the container T containing food S is packaged in the container packaging device 1 and transported. Furthermore, because these shock-absorbing materials have elasticity as well as shock absorption properties, they can be easily inserted into the container packaging device 1 through the opening A1 or A2 even if the height (thickness) of the flange V of the container T is somewhat large.

[0035] The convex strips C1L, C2L, C1R, and C2R may be formed by applying a silicone-based, polyurethane-based, acrylic-based, or other caulking material (sealing material), or by applying an ultraviolet-curing silicone adhesive, etc., rather than by adhering a rod-shaped object having a required cross-sectional shape to the required position on the inner surface of the left side surface member 4 or the right side surface member 5.

[0036] By making all or part of the top surface material 2, bottom surface material 3, left surface material 4, and right surface material 5 out of a transparent or highly transparent hard synthetic resin sheet such as a transparent material such as polyethylene terephthalate or a highly transparent polypropylene, when a container T containing food S is stored in the container packaging device 1 as shown in Figure 5, the food S can be seen from outside the container packaging device 1. Therefore, the container packaging device 1 can be displayed in a sales area of ​​a store with the food S still inside.

[0037] For example, the top surface material 2 may be made of an opaque material such as paperboard, and an opening of a required size may be provided in the top surface material 2 and covered with a transparent film, so that the food S in Fig. 5, for example, can be seen from outside the top surface material 2. Therefore, the container / packaging device 1 can be displayed in a store sales area with the food S still inside.

[0038] As shown in Fig. 1, the container packaging device 1 is sleeve-shaped and has openings A1 and A2 at both ends. Therefore, when food S shown in Fig. 5 needs to be pre-cooled to maintain freshness, cold air can easily pass through the container packaging device 1, allowing the food S to be pre-cooled efficiently.

[0039] The top surface material 2, bottom surface material 3, left side surface material 4, and right side surface material 5 are made of paperboard or hard synthetic resin sheets, for example, with a thickness of about 0.2 mm to 0.8 mm. As a result, when the container T containing food S is not stored as shown in FIG. 1-2, it can be deformed by being crushed and flattened. Therefore, the container packaging device 1 can be reduced in volume when stored or transported alone, thereby reducing storage costs and transportation costs.

[0040] When a container T containing food S is stored in the container packaging device 1 and the left and right flanges V are supported by the left and right flange support portions H as shown in Figure 5, a first gap G1 exists between the food S and the top surface member 2, and a second gap G2 exists between the container T and the bottom surface member 3. Even when the container packaging device 1 is turned upside down as shown in Figure 6, and the container T containing food S is turned upside down, the first gap G1 exists between the food S and the top surface member 2, and a second gap G2 exists between the container T and the bottom surface member 3.

[0041] Therefore, even if the container packaging device 1 vibrates up and down due to vibrations during transport such as air transport or truck transport, the food S will not collide with the top surface material 2 of the container packaging device 1, and the container T containing the food S will not collide with the bottom surface material 3 of the container packaging device 1. This makes it possible to prevent damage to the food S stored in the container packaging device 1 (main effect).

[0042] Furthermore, since the flange V is supported by the flange support portion H so that the first gap G1 and the second gap G2 remain even when the container packaging device 1 is turned upside down, even if the container packaging device 1 is turned upside down for some reason and the container T and food S are upside down and vibrate in the vertical direction, damage to the food S stored in the container packaging device 1 can be suppressed (main effect).

[0043] In the first modified example of the container packaging device 1 shown in Figure 7-8, the same reference numerals as those in the container packaging device 1 shown in Figure 1-2 indicate the same or corresponding members or parts. In the container packaging device 1 shown in Figure 7-8, the top surface material 2, bottom surface material 3, left side surface material 4, and right side surface material 5 are also integrally made of paperboard or a hard synthetic resin sheet or the like.

[0044] In the first modified example of the container packaging device 1 shown in Figure 7-8, the left recessed strip CSL in the front-to-back direction, which is the flange support portion H, is a left recessed portion DL formed by deforming the middle portion of the left side panel 4 in the up-down direction to the left (in the direction of arrow L), and the right recessed strip CSR in the front-to-back direction, which is the flange support portion H, is a right recessed portion DR formed by deforming the middle portion of the right side panel 5 in the up-down direction to the right (in the direction of arrow R).

[0045] In the first modified example of the container packaging device 1 shown in Fig. 7-8, when the container T containing the food S is not stored in the container packaging device 1 in the state shown in Fig. 7-8, the container packaging device 1 can be deformed by being crushed and flattened. Therefore, the container packaging device 1 can be reduced in volume when stored or transported alone, thereby reducing storage costs and transportation costs.

[0046] As shown in Figure 9, when a container T containing food S is stored in the container packaging device 1 and the left and right flanges V are supported by the left and right flange support portions H, a first gap G1 is formed between the food S and the upper surface member 2, and a second gap G2 is formed between the container T and the lower surface member 3. Even when the container packaging device 1 is turned upside down as shown in Figure 10, and the container T containing food S is turned upside down, the first gap G1 is formed between the food S and the upper surface member 2, and a second gap G2 is formed between the container T and the lower surface member 3. Therefore, the same effects as the main effects described above are achieved.

[0047] In the second modified example of the container packaging device 1 shown in Figure 11-12, the same reference numerals as those in the container packaging device 1 shown in Figure 1-2 indicate the same or corresponding members or parts. In the container packaging device 1 shown in Figure 11-12, the left side surface material 4 consists of an upper left side surface material 4U, a lower left side surface material 4L, and a left band plate material 6L, and the right side surface material 5 consists of an upper right side surface material 5U, a lower right side surface material 5L, and a right band plate material 6R.

[0048] The cross-sectional shape of the member consisting of the top panel 2 and the upper left side panel 4U and upper right side panel 5U is approximately U-shaped, and the cross-sectional shape of the member consisting of the bottom panel 3 and the lower left side panel 4L and lower right side panel 5L is approximately U-shaped.

[0049] The left side surface member 4 is formed by separating the lower end of the upper left side surface member 4U from the upper end of the lower left side surface member 4L, abutting the left band plate member 6L from the outside in the left-right direction across the upper left side surface member 4U and the lower left side surface member 4L, and bonding the joint surface J1 between the left band plate member 6L and the lower part of the upper left side surface member 4U and the joint surface J2 between the left band plate member 6L and the upper part of the lower left side surface member 4L. Between the upper left side surface member 4U and the lower left side surface member 4L is a left recessed strip CSL in the front-to-rear direction, and the left recessed strip CSL becomes the flange support part H.

[0050] The right side surface member 5 is formed by separating the lower end of the upper right side surface member 5U from the upper end of the lower right side surface member 5L, abutting the right band plate member 6R from the outside in the left-right direction across the upper right side surface member 5U and the lower right side surface member 5L, and bonding the joint surface K1 between the right band plate member 6R and the lower part of the upper right side surface member 5U and the joint surface K2 between the right band plate member 6R and the upper part of the lower right side surface member 5L. Between the upper right side surface member 5U and the lower right side surface member 5L is a right recessed strip CSR in the front-to-rear direction, and the right recessed strip CSR becomes the flange support part H.

[0051] 11-12, the top surface material 2, the bottom surface material 3, the upper left side surface material 4U, the lower left side surface material 4L, the upper right side surface material 5U, and the lower right side surface material 5L are relatively thick, for example, cardboard sheets (including plastic cardboard sheets) with a thickness of about 4 mm to 10 mm. The left band plate material 6L and the right band plate material 6R are cardboard sheets, paperboard, hard synthetic resin sheets, or the like.

[0052] 11-12, the second modified container packaging device 1 can also be deformed by being crushed and flattened when in the state of FIG. 11-12 in which the container T containing the food S is not stored. Therefore, the container packaging device 1 can be reduced in volume when stored or transported alone, thereby reducing storage costs and transportation costs.

[0053] As shown in Figure 13, when a container T containing food S is stored in the container packaging device 1 and the left and right flanges V are supported by the left and right flange support portions H, a first gap G1 is formed between the food S and the upper surface member 2, and a second gap G2 is formed between the container T and the lower surface member 3. Even when the container packaging device 1 is turned upside down as shown in Figure 14, and the container T containing food S is turned upside down, the first gap G1 is formed between the food S and the upper surface member 2, and a second gap G2 is formed between the container T and the lower surface member 3. Therefore, the same effects as the main effects described above are achieved.

[0054] In the third modified example of the container packaging device 1 shown in Figures 15-16, the same reference numerals as those in the container packaging device 1 shown in Figures 1-2 indicate the same or corresponding members or parts. In the container packaging device 1 shown in Figures 15-16, the left side surface material 4 consists of an upper left side surface material 4U and a lower left side surface material 4L that are separated into upper and lower parts, and the right side surface material 5 consists of an upper right side surface material 5U and a lower right side surface material 5L that are separated into upper and lower parts.

[0055] The cross-sectional shape of the member consisting of the top panel 2 and the upper left side panel 4U and upper right side panel 5U is approximately U-shaped, and the cross-sectional shape of the member consisting of the bottom panel 3 and the lower left side panel 4L and lower right side panel 5L is approximately U-shaped.

[0056] As shown in Fig. 16, a flange support portion H is formed between the lower end of the upper left side member 4U and the upper end of the lower left side member 4L, and a flange support portion H is formed between the lower end of the upper right side member 5U and the upper end of the lower right side member 5L. As shown in Fig. 15, the flange V of a container T containing food S is placed on the upper ends of the lower left side member 4L and the lower right side member 5L, and with the upper left side member 4U and the upper right side member 5U placed on the flange V, the periphery of the upper side member 2, the lower side member 3, the left side member 4, and the right side member 5 is covered with a film material 7 as shown in Fig. 16.

[0057] In the third modified container package 1 shown in Figs. 15-16, the top surface material 2, bottom surface material 3, left side surface material 4, and right side surface material 5 are cardboard sheets having a thickness of, for example, about 4 mm to 10 mm.

[0058] 15-16, when no container T containing food S is stored, the two members having a generally U-shaped cross section, namely the top surface member 2 and the upper left side surface member 4U and the upper right side surface member 5U, and the bottom surface member 3 and the lower left side surface member 4L and the lower right side surface member 5L, can be crushed and deformed to become flat. Therefore, the container packaging device 1 can be reduced in volume when stored or transported alone, thereby reducing storage and transportation costs.

[0059] As shown in Figure 16, when a container T containing food S is stored in the container packaging device 1 and the left and right flanges V are supported by the left and right flange support portions H, a first gap G1 is formed between the food S and the upper surface member 2, and a second gap G2 is formed between the container T and the lower surface member 3. Even when the container packaging device 1 is turned upside down as shown in Figure 17, and the container T containing food S is turned upside down, the first gap G1 is formed between the food S and the upper surface member 2, and a second gap G2 is formed between the container T and the lower surface member 3. Therefore, the same effects as the main effects described above are achieved.

[0060] As described above, the container packaging device 1 of the present invention is in a sleeve-like form. The term "sleeve-like" includes those that are in a "sleeve-like" form before a container T containing food S is placed inside, as shown in Figures 1-2, 7-8, and 11-12, and those that are in a "sleeve-like" form after a container T containing food S is placed inside, as shown in Figures 15-16.

[0061] Furthermore, if the container T containing the food S is a suspended container such as that shown in Patent Document 2, the food S placed in the suspended container T is suspended within the container T, and is further suspended by the container packaging device 1 of the present invention. This provides doubly protected food S from impact, dramatically improving the protective effect of the food S. It is therefore also possible to reduce the degree to which the container T itself is suspended to some extent. By adopting a simpler suspension structure for the container T, the cost of the container T can be reduced, which can be extremely advantageous industrially.

[0062] The above description of the embodiments is given by way of example only and is not intended to be limiting, and various improvements and modifications can be made without departing from the scope of the present invention. [Explanation of symbols]
