(Embodiment 1)
The transport container with a lid according to the first embodiment will be described with reference to FIGS. Each direction used in the following description is based on the state in which the container is assembled.

  As shown in FIG. 1, the carrying container with a lid according to the present embodiment covers a rectangular plate-shaped bottom plate 1, a rectangular frame-shaped mouth frame 2 positioned above the bottom plate 1, and an opening of the mouth frame 2. And 4 side plates 4 attached between the bottom plate 1 and the mouth frame 2. A heat insulating sheet 9 is provided on each of the plates 1, 3, and 4 constituting the cubic container (see FIGS. 1, 2, 5, etc.).

  The four side plates are composed of a pair of swing plates 5 mainly composed of a plate material made of synthetic resin and a pair of bent plates 6 composed mainly of a plate material made of synthetic resin.

  Each bent plate 6 is rotatably connected to the mouth frame 2 and is rotatably connected to a lower frame 11 included in the bottom plate 1. Each folding plate 6 has a structure that can be bent in a square shape toward the inside. The swing plate 5 has a structure that is rotatably connected to the mouth frame 2 and is detachably locked to the lower frame 11.

  The heat insulating sheet 9 has, for example, a structure in which an aluminum film is laminated on a foamed resin plate, but a sheet having a structure can be used as long as it has heat insulating properties.

  Hereafter, each structure of the transport container with a lid | cover of this embodiment is described in more detail.

(Bottom plate)
As shown in FIGS. 5 and 7, the bottom plate 1 integrally includes a synthetic resin-made bottom plate main body 10 and a synthetic resin-made lower frame 11 provided on the periphery of the bottom plate main body 10. On the upper surface of the bottom plate body 10, a rectangular recess 101 that can accommodate the rectangular heat insulating sheet 9, four hooks 102, and two hooks 103 are provided. Yes. The four hook portions 102 are portions where the four corner portions of the heat insulating sheet 9 housed in the recess 101 are respectively hooked. The two hook portions 103 are portions where the pair of long side portions of the heat insulating sheet 9 are respectively hooked. The heat insulating sheet 9 is retained from the recess 101 by the heat insulating sheet 9 being hooked on the hooks 102 and 103. Although the bottom plate 1 is easily contaminated, since the heat insulating sheet 9 is only hooked on the bottom plate 1, it is easy to remove and wipe the heat insulating sheet 9 once or to replace the heat insulating sheet 9.

  The lower frame 11 integrally includes a pair of long side frames 111 to which the pair of bent plates 6 are rotatably connected, and a short side frame 112 to which the pair of swing plates 5 are respectively locked. A plurality of support shafts 113 protrude upward from the long side frame 111. Since the lower edge portion 69 of the bent plate 6 is rotatably connected to each support shaft portion 113, the bent plate 6 is rotatably connected to the lower frame 11.

  The heat insulating sheet 9 is positioned substantially flush with the peripheral portion 105 surrounding the recess 101 in the upper surface of the bottom plate main body 10 in the state of being accommodated in the recess 101.

  The four hook portions 102 each have an L-shaped outer shape in plan view. Each hook 102 is extended from the peripheral portion 105 so as to cover the four corner portions of the recess 101. Each hook 102 does not have to be L-shaped in plan view, and may be constituted by a pair of linear pieces extending in directions orthogonal to each other, for example. Further, a step may be formed between each hook portion 102 and the peripheral portion 105.

  Each hook portion 103 is extended from the peripheral portion 105 to be flush with each other and has an outer shape that is straight in a plan view. A step may be formed between each hook 103 and the peripheral portion 105.

  However, if the upper surfaces of the hooks 102 and 103 and the peripheral portion 105 are connected to each other, there is an advantage that the contents are not easily tilted and an advantage that the contents are prevented from being caught by a step. .

(Mouth frame)
The mouth frame 2 is made of a synthetic resin, and a pair of short side frames 21 to which the pair of swing plates 5 are rotatably connected, and a pair of lengths to which the pair of bent plates 6 are rotatably connected, respectively. The side frame 22 is integrally provided.

From each long side frame 22, the some spindle part 23 protrudes below (refer FIG. 2).

By being connected to the frame 2 so as to be rotatable, the bent plate 6 is connected to the mouth frame 2 so as to be rotatable.
The

(Cover plate)
As shown in FIG. 1 and the like, the lid plate 3 is formed in a rectangular plate shape using a synthetic resin. On the upper surface of the lid plate 3, a recess 31 is provided that can accommodate the heat insulating sheet 9 for the lid. In a state where the heat insulating sheet 9 is housed in the recess 31, the four corner portions of the heat insulating sheet 9 are locked to the cover plate 3 by triangular locking members 35, respectively.

(Oscillating plate)

  The swing plate 5 is mainly composed of a rectangular plate 59 made of synthetic resin. A recess 51 in which the rectangular heat insulating sheet 9 can be stored is provided on the inner surface of the plate 59 (the surface facing the storage space when assembled). In a state in which the heat insulating sheet 9 is housed in the recess 51, the four corner portions of the heat insulating sheet 9 are locked to the plate material 59 by the triangular locking members 55, respectively.

  Specifically, as shown in FIG. 10, through holes 95 are respectively formed in the four corner portions of the heat insulating sheet 9, and the portions corresponding to the through holes 95 in the recess 51 on a one-to-one basis, A protruding rib 512 is formed. In a state where the heat insulating sheet 9 is stored in the recess 51, the four protruding ribs 512 are fitted into the corresponding through holes 95. The projecting rib 512 has a rectangular frame shape in which four long pieces are connected to each other, but is not limited thereto, and may have a shape in which, for example, the four long pieces are separated from each other.

  As shown in FIG. 11, the locking member 55 includes a protrusion 552 provided so as to fit in the central hole of the protruding rib 512 and two elastic pieces provided so as to be elastically hooked to the plate material 59. 554 are integrally provided. The protrusion 552 is fitted in the central hole of the protruding rib 512 fitted in each through hole 95 of the heat insulating sheet 9 and is elastic with respect to the groove 514 (see FIG. 10) provided on the side surface of the recess 51. The locking member 55 is attached to the plate member 59 by the 554 being elastically hooked.

  As shown in FIG. 8, the first contact surface 501 and the second contact surface 502 are separated from each other across the step 505 at the side end portion 50 of the swing plate 5 (that is, the side end portion of the plate material 59). Located.

  Both the first contact surface 501 and the second contact surface 502 are provided in a straight line in the vertical direction. Both the first contact surface 501 and the second contact surface 502 are flat and elongated so as to be orthogonal to the thickness direction of the swing plate 5 and are parallel to each other.

  The first contact surface 501 and the second contact surface 502 are located at a distance from each other in the thickness direction of the swing plate 5. The first contact surface 501 is located outside the second contact surface 502 (the side away from the storage space).

  As will be described later, both the first contact surface 501 and the second contact surface 502 are in contact with the side end portions of the adjacent bent plates 6, thereby improving the airtightness of the storage space.

(Folded board)
12 to 14 show the whole or a part of the bent plate 6. The bent plate 6 has a structure that can be folded in half in a square shape.

  The bent plate 6 includes a synthetic resin frame 63, a synthetic resin inner frame 64, and a rectangular heat insulating sheet 9 sandwiched between the frame 63 and the inner frame 64.

  The frame 63 includes an upper frame 631 and a lower frame 632 that is rotatably connected thereto. The upper frame 631 and the lower frame 632 are connected so as to be bent in a square shape toward the inside.

  The inner frame 64 includes an upper inner frame 641 and a lower inner frame 642.

  The upper inner frame 641 is detachably attached to the upper frame 631 with the upper half of the heat insulating sheet 9 sandwiched between the upper frame 631 and the upper frame 631. Specifically, a plurality of through holes 97 are formed in the upper half portion of the heat insulating sheet 9, and locking pieces 633 are respectively formed at positions corresponding to the through holes 97 in the upper frame 631 on a one-to-one basis. Has been. In a state in which the locking pieces 633 are fitted in the respective through holes 97, the plurality of locking pieces 643 (see FIG. 14) provided on the upper inner frame 641 are elastic to the corresponding locking pieces 633 on a one-to-one basis. Lock to.

  The lower inner frame 642 is detachably attached to the lower frame 632 in a state where the lower half portion of the heat insulating sheet 9 is sandwiched between the lower inner frame 642 and the lower frame 632. A specific structure in which the lower inner frame 642 is attached to the frame 632 is similar to the above-described structure in which the upper inner frame 641 is attached to the frame 631.

  The heat insulating sheet 9 attached to the bent plate 6 is formed with a straight fold line portion 91 so as to be bent in a square shape toward the inside. The broken line portion 91 is formed, for example, by providing a groove in the central portion of the heat insulating sheet 9 by hot pressing, or by sewing the central portion of the heat insulating sheet 9 with a thread. The upper half and the lower half of the heat insulating sheet 9 are partitioned with the fold line portion 91 as a boundary.

  As shown in FIG. 1, an opening 635 is formed in the frame 63 so as to expose a partial region A1 at the center of the heat insulating sheet 9 to the outside. The opening 635 is an opening formed between the upper frame 631 and the lower frame 632, and has a hexagonal opening edge that is long in the horizontal direction when the container is assembled.

  More specifically, the upper frame 631 includes a horizontally long long piece 6314 that is attached from the outside so as to cover the upper end of the heat insulating sheet 9, and extends downward from both horizontal ends of the long piece 6314. A pair of connecting pieces 6315 is provided. The lower frame 632 is a horizontally long long piece 6324 that is mounted from the outside so as to cover the lower end of the heat insulating sheet 9, and a pair of connections extending upward from both horizontal ends of the long piece 6324. A piece 6325 is provided. The upper and lower frames 631 and 632 are rotatably connected to each other by connecting the tip portions of the connecting piece 6315 and the connecting piece 6325 facing each other in a vertically rotatable manner.

  The opening edge of the opening 635 has a lower end edge of the long piece 6314 included in the upper frame 631, side edge edges of the pair of connecting pieces 6315 included in the upper frame 631, and a length of the lower frame 632. The upper end edge of the piece 6324 and the opposite side edge edges of the pair of connecting pieces 6325 included in the lower frame 632 are formed in a hexagonal shape.

  The partial region A1 of the heat insulating sheet 9 exposed to the outside by the opening 635 is a region including the folded line portion 91 and its peripheral portion, and this region is a portion that swells when the heat insulating sheet 9 is folded into a square shape. It is. Therefore, if the opening 635 is not formed, there is a problem that the bent plate 6 is difficult to be broken and a problem that the heat insulating sheet 9 is easily damaged due to repeated bending operations.

  On the other hand, when the partial area A1 at the center of the heat insulating sheet 9 is opened to the outside by the opening 635, the folding plate 6 is easily broken, and the heat insulating sheet 9 is damaged by repeated bending operations. It becomes difficult.

  In addition, when only a part of the fold line part 91 of the heat insulating sheet 9 is not exposed by the opening part 635 (for example, the end part of the fold line part 91 is covered by the frame 63 and the other part is exposed through the opening part 635. In the case), the heat insulating sheet 9 is easily damaged at the boundary between the exposed part and the other part. Therefore, it is preferable that at least the entire broken line portion 91 is exposed through the opening 635.

  Furthermore, in the transport container with a lid according to the present embodiment, an edge-shaped corner pointed at an angle α is formed at the horizontal end of the opening 635. The edges of the corners are formed by connecting the side end edges of the upper and lower connecting pieces 6315 and 6325 in a <(>) shape. The corner angle α is smaller than 180 °, and more preferably an obtuse angle. When the angle α is an acute angle, the folded heat insulating sheet 9 is likely to bite into the edge of the corner of the opening 635, and the heat insulating sheet 9 is likely to be damaged.

  The upper edge portion 60 of the bent plate 6 connected to the mouth frame 2 is constituted by an upper frame 631 and an upper edge portion of the inner frame 641. A plurality of upper edge protrusions 601 protrude upward from the upper edge portion of the upper frame 631 (see FIG. 2 and the like). The plurality of upper edge protrusions 601 are positioned at a distance from each other in the horizontal direction. A protrusion 602 that is rotatably connected to the mouth frame 2 protrudes from the upper edge protrusion 601 in the horizontal direction.

  A plurality of cover portions 61 protrude upward from the upper edge portion of the inner frame 641. Each cover part 61 is located so that a part of space between adjacent upper edge protrusions 601 may be covered from the inside (see FIG. 12). In the horizontal direction, the upper edge protrusions 601 and the cover parts 61 are located alternately.

  As shown in FIG. 2, in a state where the bent plate 6 and the mouth frame 2 are connected, the support shaft portion 23 that protrudes downward from the mouth frame 2 has a plurality of upper edge protrusions that protrude upward from the bent plate 6. It is located in the space between the parts 601. Each cover portion 61 is located below the support shaft portion 23 protruding from the mouth frame 2. Each cover portion 61 functions to seal the ventilation in the space between the adjacent upper edge protrusions 601 in cooperation with the support shaft portion 23 when the container is in an assembled state (FIG. 2). FIG. 3). Here, sealing the ventilation is not limited to completely sealing the ventilation. In the transport container with a lid according to the present embodiment, the cover portions 61 are provided not on the mouth frame 2 but on the bent plate 6, thereby preventing the cover portions 61 from interfering with the rotation operation of the bent plate 6. ing.

  In addition, in the transport container with a lid according to the present embodiment, first vertical ribs 65 and second vertical ribs 66 that are long in the vertical direction are provided at the side end of the bent plate 6 (see FIG. 12 and the like). The first vertical rib 65 is located on the outer side (the side away from the storage space) than the second vertical rib 66. The first vertical rib 65 and the second vertical rib 66 are parallel to each other.

  The 1st vertical rib 65 is comprised so that the 1st contact surface 501 formed in the rocking | fluctuation board 5 may contact | abut (refer FIG. 15). The second vertical rib 66 is configured such that a second contact surface 502 formed on the swing plate 5 contacts. Thereby, the distance between the air passages is reduced by the heat insulation effect by blocking the air flow between the swing plate 5 and the bent plate 6 in two stages and the presence of the first contact surface 501 and the second contact surface 502. The heat insulation effect by becoming long can be acquired. Further, the presence of the first contact surface 501 and the second contact surface 502 suppresses deformation of the swing plate 5, and the presence of the first vertical rib 65 and the second vertical rib 66 (rib reinforcing effect) causes bending. The deformation of the plate 6 is suppressed, and thereby a heat insulating effect due to the fact that a gap is hardly generated between the swing plate 5 and the bent plate 6 can be obtained.

  In addition, in the transport container with a lid according to the present embodiment, the upper surface of the upper edge protrusion 601 of the bent plate 6 is further suppressed in order to further suppress the formation of a ventilation space between the bent plate 6 and the mouth frame 2. Accordingly, a straight rib 603 long in the horizontal direction is projected (see FIG. 4).

  Here, the long side frame 22 of the mouth frame 2 has an inner partition 225 and an outer partition 226, and a hollow portion provided between both the partitions 225 and 226 is opened downward.

  In a state where the container is assembled, the rib 603 of the bent plate 6 is located in the hollow portion of the long frame 22 and is located in contact with or close to the inner partition wall 225, thereby suppressing the ventilation. Demonstrate.

  In addition, in the transporting container with a lid according to the present embodiment, in order to suppress the formation of a ventilation space between the bent plate 6 and the lower frame 11, it is possible to A straight rib 115 extending in the direction is projected (see FIG. 6).

  In a state where the container is assembled, the rib 115 of the lower frame 11 is located below the lower edge portion 69 of the bent plate 6. The rib 115 exerts a function of suppressing ventilation by being in contact with or close to the lower surface of the lower edge portion 69.

  Since the transporting container with a lid according to the present embodiment has the above-described configurations, the container as a whole exhibits high heat insulating properties (cold insulation and thermal insulation functions). In particular, when a sheet-like cold insulating material (not shown) is fixed to the lid plate 3 or when the cold insulating material is placed on the mouth frame 2, the entire container can exhibit a high cold insulating function.

(Modification)
As mentioned above, although the transport container with a lid of this embodiment was explained, the transport container with a lid is not limited to this embodiment.

  For example, in the transport container with a lid of the present embodiment, the inner frame 641 and the cover portion 61 on the upper side of the bent plate 6 are integrally formed, and the heat insulating sheet 9 is attached by combining this with the frame 631. The upper frame 631 and the cover portion 61 are integrally formed, and the inner frame 641 is combined with the upper frame 631 to attach the heat insulating sheet 9, or the upper frame 631 and the cover portion 61 are integrally formed. It is also possible to attach the heat insulating sheet 9 using an appropriate locking member instead of the frame 641 (that is, without the inner frame 641). Further, the upper frame 631, the inner frame 641, and the cover portion 61 can be integrally formed. Similarly, the lower frame 632 and the inner frame 642 can be integrally formed on the lower side of the bent plate 6.

  When the upper frame 631 and the cover portion 61 (or the inner frame 641) are molded integrally, it is difficult to mold the protrusions 602 (see FIG. 12 etc.) integrally due to the convenience of the mold. For example, it is preferable to form a portion corresponding to the protrusion 602 by inserting a separate resin pin (not shown).

  Further, in the transport container with a lid of the present embodiment, the heat insulating sheet 9 is entirely covered with the plate material 59 formed so as to have sufficient bending rigidity and impact resistance, but the structure of the plate material 59 is this. Any suitable injection-molded product, press plate, or the like can be used as long as it has a structure that covers at least a part of the heat insulating sheet 9 and has a predetermined bending rigidity and impact resistance.

  Further, in the transport container with a lid of the present embodiment, the opening 635 of the frame 63 included in the bent plate 6 is provided in a hexagonal shape, but the shape of the opening 635 is not limited to this, and at least the bent line portion 91. Any shape may be used as long as the partial region A1 including the surface is exposed to the outside. Therefore, for example, the edge shape of the end portion in the horizontal direction of the opening 635 may be an appropriate curved shape instead of the <character shape.

  Further, in the transport container with a lid according to the present embodiment, the side edge of each connecting piece 6315 included in the upper frame 631 (part constituting a part of the opening edge of the opening 635) is provided in a straight line. As in the modification shown in FIG. 16, each connecting piece 6315 can be provided with a protruding portion 6317 protruding inward. Also in this case, the overhanging portion 6317 is formed so as to avoid the end of the fold line portion 91 in order to expose the entire fold line portion 91 to the outside.

  In the modification of FIG. 16, each connecting piece 6325 included in the lower frame 632 is similarly provided with a protruding portion 6327 protruding inward. The overhanging portion 6327 is also formed so as to avoid the end portion of the broken line portion 91.

  Here, the corners of the upper and lower overhang portions 6317 and 6327 have a sharp outline at an angle β. If the angle β is a right angle or an acute angle, the bent heat insulating sheet 9 is likely to break into the corners of the overhanging portions 6317 and 6327, so that the angle β is preferably an obtuse angle. Further, in order to suppress the biting of the heat insulating sheet 9, the corner portions of the upper and lower overhang portions 6317 and 6327 are smoothly chamfered (that is, the peripheral edges of the corner portions of the overhang portions 6317 and 6327 are formed with smooth convex curves. It is also preferable.

  Further, in the transport container with a lid according to the present embodiment, the heat insulating sheet 9 is detachably provided on each of the plates 1, 3, 4. For example, at least a part of the heat insulating sheet 9 is provided by means such as insert molding. It is also possible to have a structure covered with the plates 1, 3, 4.

  Further, with the heat insulating sheet 9 attached to each of the plates 1, 3, and 4, another sheet material can be attached by heat welding or the like so as to cover the heat insulating sheet 9. In this case, it is difficult to form a gap around the heat insulating sheet 9, and there is an advantage that dew condensation water can be suppressed around the heat insulating sheet 9 and an advantage that the waterproofness when washing the container with water is improved. is there.

  With regard to other configurations provided in the transport container with a lid according to the present embodiment, it is possible to make an appropriate design change or to combine known techniques as appropriate.

(effect)
As described above with reference to the accompanying drawings, the carrying container with a lid according to this embodiment is mounted so as to close the bottom plate 1, the mouth frame 2 positioned above the bottom plate 1, and the opening of the mouth frame 2. And four side plates 4 provided so as to stand between the bottom plate 1 and the mouth frame 2. The bottom plate 1, the cover plate 3, and the four side plates 4 each have a heat insulating sheet 9.

  In the transport container with a lid according to the present embodiment, the four side plates 4 include a pair of swing plates 5 that are swingably connected to the mouth frame 2, and a bottom plate 1 that is bent into a square shape as a whole. It comprises a pair of bent plates 6 connected to the mouth frame 2. Each bent plate 6 is erected from the upper edge portion 60 so as to seal the ventilation space formed between the upper edge portion 60 provided to be freely rotatable with respect to the mouth frame 2 and the mouth frame 2. The cover portion 61 is provided.

  Therefore, according to the transporting container with a lid of the present embodiment, the entire container can be folded compactly by operating each swing plate 5 and each folding plate 6, so that the contents can be conveyed to the destination. After it becomes empty, it can be folded and collected, stored, etc., and space saving can be achieved. And in the container with a cover of this embodiment, the heat insulation as a whole container is high by sealing the ventilation space which arises between the upper edge part 60 of each bending board 6 and the mouth frame 2 with the cover part 61. FIG. It can exhibit the properties (cooling and heat retaining functions).

  In addition, in the transporting container with a lid according to the present embodiment, each folding plate 6 sandwiches at least a part of the heat insulating sheet 9 between the frame 63 and the frame 63 provided so as to be bent in a square shape. An inner frame 64 is further provided. The cover part 61 is formed integrally with the inner frame 64.

  Therefore, according to the transporting container with a lid of the present embodiment, the folding plate having a high heat insulating property is obtained by a simple operation of forming the frame 63 and the inner frame 64 and sandwiching the heat insulating sheet 9 therebetween. 6 can be formed efficiently.

  Further, in the transporting container with a lid, the side end portion 50 of each swing plate 5 is provided so as to contact a part of the bent plate 6 (first vertical rib 65) and seal the ventilation. It has a contact surface 501 and a second contact surface 502 provided so as to contact another portion (second vertical rib 66) of the bent plate 6 and seal the ventilation. The first contact surface 501 and the second contact surface 502 are positioned at a distance from each other in the thickness direction of each swing plate 5.

  Therefore, according to the transporting container with a lid of the present embodiment, the fact that a ventilation space is generated between the swing plate 5 and the bent plate 6 indicates that the bent plate at the first contact surface 501 of the swing plate 5 6 and the contact with the bent plate 6 at the second contact surface 502 can be sealed in two stages. Furthermore, since the first contact surface 501 and the second contact surface 502 are positioned, the distance of the air passage is increased, and the heat insulation is improved. Thereby, high heat insulation (cold insulation, heat insulation function) can be exhibited as the whole container.

  Moreover, in the transporting container with a lid of the present embodiment, the heat insulating sheet 9 has a fold line portion 91 that bends in a square shape. Each bent plate 6 further includes a frame 63 configured to be bent in a square shape together with the heat insulating sheet 9. The frame 63 is formed with an opening 635 that exposes a partial region A1 including the broken line portion 91 of the heat insulating sheet 9.

  Therefore, according to the transport container with a lid of the present embodiment, the portion of the heat insulating sheet 9 that expands when it is bent is opened to the outside through the opening 635, so that the folding plate 6 can be folded easily. Can be secured, and damage to the heat insulating sheet 9 due to repeated folding operations can also be suppressed.

  Further, in the transport container with a lid of the present embodiment, a plate material 59 is provided on the outer surface of each swing plate 5 so as to cover a part or all of the heat insulating sheet 9.

  Therefore, according to the transporting container with a lid of the present embodiment, since the entire bending rigidity and impact resistance of the swing plate 5 can be ensured by the plate material 59, when the entire container is folded, the swing plate 5 is used. It is possible to work by hitting from the outside.
