Description

  The present invention relates to a foamed container including a container body formed of foamed polystyrene and an upper lid, and more particularly, to a foamed container for packing (double packing) a cardboard box.

  2. Description of the Related Art Conventionally, foam containers made of a synthetic foam resin having excellent heat insulation properties have been widely used to accommodate and transport fresh food products. For example, some fresh foods imported from abroad are put in cardboard, stored frozen and transported to Japan. In this case, in the transportation process in Japan, a food (for example, broccoli) packed in cardboard is cold-packed (double packing of food) in a foamed polystyrene container and then divided into different shipping destinations.

  Since the foamed container is usually formed of a box-shaped container main body with one side open and a lid portion, there is a problem that a foamed container that contains nothing is bulky and not compact. Therefore, in order to make the foam container compact when not in use, a heat insulating container made of polystyrene foam is disclosed in which the container main body is divided into a bottom plate and front and rear side plates and can be assembled. (For example, refer to Patent Document 1). Further, a foamed container that is made compact by packing three container bodies constituting the foamed container in a set is also disclosed (for example, see Patent Document 2).

  By the way, when heavy foam containers are stacked in a vertical direction, the stacked foam containers become unstable, and load collapse is likely due to vibration during transportation such as a forklift. Therefore, so-called “yes stacking” in which foam containers are stacked in different directions is generally used. A foamed container is disclosed in which discharged water does not contaminate the outer surface of the container when the container is stored or transported by “stacking” the foamed container (for example, see Patent Document 3).

  A foam container according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 (a) shows a foaming container 1 for further packaging (double packaging) a cardboard box filled with fresh foods such as broccoli that has been kept cold, and keeping cold and sorting and transporting. The foamed container 1 is formed of a foamed synthetic resin, and as shown in FIG. 1B, a box-shaped container body 2 having an upper surface opened and an upper lid 3 attached from the upper surface of the container body 2 Composed. The foamed synthetic resin is a polyolefin resin such as polystyrene, polyethylene, or polypropylene.

  First, the shape of the container main body 2 constituting the foam container 1 will be described with reference to FIG. The container body 2 has a box shape in which one surface is opened, and the inner bottom surface 2a has a bottom surface such as a cardboard box in which broccoli is accommodated, as shown in FIG. The trapezoidal mounting table 2b is formed at a plurality of locations (six locations in the present embodiment). The foam container 1 can maintain the cold-reserving function by filling the inner bottom surface 2a excluding the mounting table 2b with crushed ice and attaching and sealing the upper lid 3. And the container main body 2 becomes a magnitude | size of long side dimension 582 (mm) x short side dimension 365 (mm) x height dimension 161 (mm), for example.

  Since the corrugated cardboard box packed with food is kept cold and transported in a state of being placed on the placing table 2b of the container body 2, it is possible to prevent the food in the cardboard box from being melted. For this reason, for example, when a cardboard box packed with broccoli, which is an example of fresh food, is packed (double packed) in the foamed container 1 and transported, the water is melted into the broccoli from the portion immersed in the water of the cardboard box. As a result, it is possible to reliably prevent the problem that ethylene gas is generated and broccoli ripening is promoted.

  On the upper end 2c of the container body 2, as shown in FIG. 2 (e), guide grooves 2d as recesses and guide protrusions 2e as projections are alternately arranged to be fitted to the upper lid 3 (or another container body 2). It is formed in two circles in a ring shape along the circumferential direction. Moreover, the formation pattern of the guide groove 2d and the guide protrusion 2e is reversed every different circumference. The guide groove 2d is fitted with the guide protrusion 3e of the upper lid 3 when the upper lid 3 is attached, and the guide protrusion 2e is fitted with the guide groove 3d of the upper lid when the upper lid 3 is attached, so that the upper lid 3 is attached to the container body 2. The airtightness of the foamed container 1 can be maintained. When the container main bodies 2 are fitted to each other, the guide groove 2d is fitted with the guide protrusion 2e of another container main body 2 with the top and bottom reversed, and the guide protrusion 2e is another container main body 2 with the top and bottom reversed. The guide groove 2d is fitted.

  When the outer bottom surface 2f of the container body 2 is stacked with a plurality of bottom surface recesses 2g and foamed containers 1 stacked for forming the mounting table 2b, as shown in FIG. A bottom surface step 2h is formed for lightly engaging with the peripheral step 3b of the upper lid 3 located at the top.

  Here, the bottom step 2h will be described in detail with reference to FIG. The bottom step 2h is arranged on the four corners of the outer bottom surface 2f, and at least two sides 2ha and 2hb parallel to the long side surface direction of the container body 2 and two sides 2hc parallel to the short side surface direction of the container body 2 , 2hd, and is formed in a substantially rectangular shape in this embodiment.

  And as a dimension, the height dimension of the bottom face step part 2h is 3 (mm). Further, as shown in FIG. 3, of the two sides 2hc and 2hd parallel to the long side surface direction of the outer bottom surface 2f of the container body 2 and parallel to the short side surface direction of the bottom surface step portion 2h from one side of the outer bottom surface 2f. Distance to one side 2hc located outside: Distance between two sides 2hc and 2hd parallel to the short side surface direction of bottom step 2h: Inside of two sides 2hc and 2hd parallel to the short side direction of bottom step 2h The ratio of the distance between the sides 2hd located at is 36: 115: 280 (mm). Further, in a direction parallel to the short side surface direction of the outer bottom surface 2f of the container body 2, from one side of the outer bottom surface 2f to one side 2ha located outside of the two sides 2ha and 2hb parallel to the long side surface direction of the bottom surface step 2h. Distance: distance between two sides 2ha, 2hb parallel to the long side surface direction of the bottom step 2h: between two sides 2ha, 2hb parallel to the long side direction of the bottom step 2h The ratio of distance is 44, 5: 82: 110 (mm). In addition, the outer surface of the container body 2 is formed with irregularities that serve as a handle during transportation.

  Next, the shape of the upper lid 3 constituting the foam container 1 will be described with reference to FIG. The upper lid 3 is formed of a box-like body having an opened lower surface, and in the present embodiment, the height dimension of the upper lid 3 is larger than the height dimension of the container body 2.

  On the periphery of the upper surface 3a of the upper lid 3, as shown in FIG. 4 (d), the outer bottom surface 2f of the container body 2 with a plurality of foamed containers 1 stacked in order to prevent the collapse of the load during the stacking. An annular peripheral step 3b is formed for lightly engaging with the bottom step 2h formed at the bottom. For example, the long side dimension 582 (mm) x the short side dimension 365 (mm) x the height dimension 265 (mm) of the upper lid 3 is set. In this case, as shown in FIG. 5, the length ratio of the peripheral step 3b: between the peripheral step 3b: the peripheral step 3b is 34: 514: 34 (mm) in the direction parallel to the long side direction, and the short side direction. The length ratio of the peripheral step 3b: between the peripheral step 3b and the peripheral step 3b is set to 27: 311: 27 (mm) in a direction parallel to Moreover, the height of the peripheral step 3b is 5 (mm).

  With this configuration, when the foam container 1 is “bar-stacked” in the vertical direction, the outer side 2hc of the two sides 2hc and 2hd parallel to the short side surface direction of the bottom step 2h is the lower lid 3 It contacts the peripheral step 3b. On the other hand, of the two sides 2ha and 2hb parallel to the long side surface direction of the bottom step 2h, the one side 2ha located outside does not come into contact with the peripheral step 3b of the upper lid 3 located in the lower step, and the one side 2ha and the periphery It is comprised so that a clearance gap may arise between step parts 3b. As a result, the gap can be adjusted, and a plurality of foam containers 1 can be “yes-stacked” in each of the five boxes and the six boxes.

  On the lower end 3c of the upper lid 3, as shown in FIG. 4 (e), guide grooves 3d as concave portions and guide projections 3e as convex portions for fitting with the container body 2 (or other upper lid 3) are alternately arranged. It is formed in two rounds along the circumferential direction. Moreover, the formation pattern of the guide groove 3d and the guide protrusion 3e is reversed for each circumference. The guide groove 3d is fitted with the guide protrusion 2e of the container body 2 when being mounted on the container body 2, and the guide protrusion 3e is fitted with the guide groove 2d of the container body 2 when being mounted with the upper lid 3. Thereby, the sealing property of the foam container 1 can be maintained. When the upper lids 3 are fitted to each other, the guide groove 3d is fitted to the guide protrusion 3e of the other upper lid 3 with the top and bottom reversed, and the guide protrusion 3e is the guide groove of the other upper lid 3 with the top and bottom reversed. Mates with 3d. As shown in FIGS. 2 and 4, when the opening surfaces of the container body 2 and the upper lid 3 are set in the same direction, the guide groove 2 d and the guide protrusion 2 e formed in the container body 2 and the upper lid 3 are formed. The formed guide groove 3d and guide protrusion 3e are formed in the same pattern.

  As shown in FIGS. 4 (e) and 4 (h), a pair (plurality) of ridges 3 g extending in the vertical direction are formed on the long side surface 3 f in the accommodation space of the upper lid 3. For example, the height dimension of the ridge 3g is 5.5 (mm).

  Further, the length dimension of the storage space of the upper lid 3 in the short side surface direction is approximately twice the height dimension of the container body 2. For example, the length dimension 319 (mm) in the short side direction of the accommodation space of the upper lid 3 and twice the height dimension of the container body 2 are 322 (mm). With these dimensions, as shown in FIG. 7 and FIG. 8, when the foam container 1 is compacted by one set of two boxes, it is accommodated in the inner space of the upper lid 3 and the two container main bodies 2 are opened. The box 4 integrated with the surfaces facing each other can be accommodated while being pressed from the outside by the ridges 3g of the upper lid 3 (see FIG. 8D, etc.), and the ridges 3g serve as a mechanism for preventing the box 4 from being displaced. . For this reason, not only can the entire volume of the foam container 1 be made compact, but the box 4 can be prevented from vibrating, and the center of gravity can be shifted during transportation and the like to prevent collapse of the load.

  Next, a method for making the foamed container 1 compact when not in use will be described with reference to FIGS. 9 and 10. First, when the foam container 1 itself is transported (when not in use), such as before and after accommodating the cardboard box, as shown in FIG. 9A, the two container bodies 2 are fitted in the direction in which the opening portions face each other. The box 4 is assembled together. Next, as shown in FIG. 9 (b), one end side in the longitudinal direction of the box body 4 is accommodated in a standing posture in the accommodation space of one upper lid 3, and the other end side of the box body 4 is accommodated. The other upper lid 3 is covered in the direction of the arrow Y with the top lid 3 turned upside down.

  Thereby, in this Embodiment, the foaming container 1 can be packed by 2 boxes 1 set, and the size reduction at the time of conveyance and the storage can be achieved. Further, since the box body 4 is pressed and fixed by the ridge 3g formed on the long side surface 3f in the accommodation space of the upper lid 3, the center of gravity of the compacted foam container 1 is stable.

  Next, a state where the foam container 1 according to the present embodiment is stacked will be described with reference to FIGS. 11 to 16.

  FIG. 11 shows a state in which the foam containers 1 are stacked in 5 boxes × 2 stages. In each stage, three boxes of foam containers 1a to 1c are arranged in a row in the direction in which the long side faces, and two boxes of foam containers 1d and 1e are arranged in a row in the direction in which the short side faces. These foam containers 1a to 1d are integrated in a rectangular shape in a plan view to constitute a foam container layer 5 of five stages. The two-stage foam container layer 5 is laminated in the vertical direction while changing its direction by 180 degrees.

  At this time, as shown in the cross-sectional views of FIGS. 12A and 12B, the foaming container 1 has the bottom surface step portion 2 h and the peripheral step portion 3 b having the above-described dimensional ratio, so that the upper foam containers 1 a to 1 b. The bottom step 2h of 1e engages with the peripheral step 3b of the lower foam containers 1a to 1e. For this reason, when the foamed container 1 sealed with a cardboard box is stacked and transported in a physical distribution, it is possible to prevent the collapse of the load, which is largely displaced or dropped. FIGS. 13 (a) and 13 (b) are photographs of the state in which the foam container 1 is actually stacked in five boxes, and it can be seen that the collapse of the load can be prevented appropriately.

  FIG. 14 shows a state in which the foam containers 1 are stacked in 6 stages × 2 stages. In each stage, three foam containers 1a to 1c and 1d to 1f are arranged in two rows in the direction in which the long sides face each other, and these foam containers 1a to 1c and 1d to 1f are integrated in a square shape in plan view. To form a foam container layer 5 of 6 boxes. Moreover, these foam container layers 5 are laminated | stacked up and down, changing the direction 90 degree | times.

  Also in this case, as shown in the cross-sectional views of FIGS. 15A and 15B, the bottom step 2h of the upper foam containers 1a to 1f and the peripheral step 3b of the lower foam containers 1a to 1f are engaged. Match. 16 (a) and 16 (b) are photographs of a state in which the foam container 1 is actually stacked in six boxes.

  As described above, in the foamed container 1 according to the present embodiment, the height dimension of the upper lid 3 is larger than the height dimension of the container body 2, and the length dimension in the short side surface direction of the accommodation space of the upper lid 3. Is approximately twice the height of the container body 2. When packing the foamed container 1 in a set of two boxes, the box body 4 in which the two container main bodies 2 are fitted in the direction in which the openings face each other is assembled, and one end side in the longitudinal direction of the box body 4 is assembled. The upper lid 3 is accommodated in an upright posture and the other end of the box 4 is covered with another upper lid 3 that is upside down from the upper lid 3. With this structure, it is possible to reduce the size of the foamed container 1 especially for packing (double packing) cardboard boxes, and the foamed container 1 can be transported and stored in a very compact state when not in use. And problems such as transportation costs can be reduced.

  Further, since the outer surface of the box 4 is pressed by the convex groove 38 accommodated in the inner space of the upper lid 3 of the foam container 1, the center of gravity is less moved during transport and storage, and two boxes are packed in one set. The foamed container 1 can be stabilized.

  Further, a bottom step 2 h is formed on the outer bottom surface of the container body 2, and this is lightly engaged with the peripheral step 3 b of the upper lid 3. For this reason, even in the case of “yes stacking” in 5 boxes or 6 boxes in each stage during distribution transportation, it is possible to reliably prevent a load collapse that is largely displaced or dropped.

  In the above-described embodiment, the foam container 1 has been described using a corrugated cardboard box for transporting broccoli. However, the foam container 1 can be applied even when transporting other general packages. it can.
