Description

  The present invention relates to a foam container made of foamed resin, which is mainly used for transporting and storing vegetables such as broccoli, other agricultural products, and fresh fish.

  In logistics such as transport and storage of vegetables and other agricultural products such as broccoli, there is heat insulation such as polystyrene foam consisting of a flat rectangular container body opened upward and a lid fitted and attached to the opening end. A container made of foamed resin is used. For example, in the case of vegetables such as broccoli, the harvested vegetables are stored in the container body, crushed ice is put on the stored vegetables and packed in ice, and the lid is attached in this state, transported in a cold state, etc. Used for logistics.

  In recent years, so-called sherbet-like slurry ice having a fluid semi-liquid state in which fine ice pieces are mixed with water has come to be used as the ice used for the ice stuffing. The sherbet-like slurry ice can be transported by a pump in the same manner as the liquid and can be easily filled into the container body. In addition, when a container having an opening is used, the filled slurry ice liquid is opened. It is possible to fix the vegetables such as broccoli and keep the vegetables fresh because the ice of the slurry ice remaining between the vegetables such as broccoli hardens in a state of wrapping the vegetables without gaps In particular, it has been attracting attention and spreading in recent years.

  As a distribution container using slurry ice for such ice filling, it is desired that the liquid can be discharged in a short time when the slurry ice is filled in order to sufficiently solidify the entire slurry ice to be filled. It is desired that the sealed state can be satisfactorily maintained so as to prevent air intrusion during transportation and not lower the cooling effect.

  In Patent Document 1, in a container made of foamed resin used for transporting fresh fish, when using sherbet-like slurry ice, the drainage effect at the time of charging and filling slurry ice is enhanced and air intrusion during transport is prevented. In order to do this, a non-penetrating water drop hole and a tunnel part that leads from the water drop hole to the outside of the container are provided on the bottom of the container, and when the slurry ice containing seawater is introduced, only seawater is dropped into the water drop hole. Thus, it has been proposed that seawater can be discharged to the outside through the tunnel portion, and that the tunnel portion can be shielded by water droplets collected in the tunnel portion during transportation so that the sealed state can be maintained.

  However, in this proposal, the water drop hole on the bottom of the container and the passage for drainage by the tunnel part are shielded only by water droplets during transportation. The shielding state becomes unstable and there is anxiety about maintaining the sealed state.

  In Patent Document 2, the bottom wall of the box is divided into an upper floor wall and a lower floor wall for the purpose of housing seafood together with water and separating sand and garbage contained in the storage from the storage. A double bottom wall is provided with a plurality of through-holes in the upper bottom wall. After the lower bottom wall is detached, the fishery products and the like are accommodated and the deposits are washed away. There has been proposed a foamed resin container that is mounted, closed, and sealed for use in transportation.

  In the case of this proposal, since the lower bottom wall is a structure that is fitted to the lower end of the side wall of the box by a concave and convex fitting structure, when the lower bottom wall is mounted, the box in which the contents are stored is stored. The body itself must be lifted, the mounting operation is not easy, and the mounting operation particularly in a stacked state is impossible. In addition, the water generated by the melting of the ice contained together with the contents is stored in the space between the upper bottom wall and the lower bottom wall, so that the box is raised and the height of the box is increased. However, the internal volume is small, and the transportation efficiency is lowered accordingly.

Has been.

  The through hole 15 of the bottom wall 14 and the through hole 35 of the bottom plate 30 are aligned with each other when the bottom plate 30 is in the incompletely inserted position, and are shifted from each other when in the fully inserted position. In order to achieve this, the through holes 15 and 35 are arranged and formed as follows, for example.

  The through hole 15 in the bottom wall 14 has a size larger than the diameter d, which is a passing dimension in the bottom plate insertion direction of the through hole 15 between the plurality of through holes 15, 15 arranged in parallel in the bottom plate insertion direction. Preferably, the distance L is 1.5 times or more of the dimension L, and the dimension between the innermost end 12a and the innermost through hole 15 in the recessed portion 12 is larger than the diameter d, preferably It is arranged and formed on the bottom wall 14 with the same dimension as the interval L remaining.

  On the other hand, the bottom plate 30 is not less than the diameter d of the through hole 15 and the through holes 15 and 15 with respect to the complete insertion position where the distal end 30a in the insertion direction contacts the innermost end 12a of the recessed portion 12. A position at which a predetermined dimension within a range of the distance L between each other is pulled out is set as the incomplete insertion position, and a position that coincides with each through-hole 15 in the bottom wall 14 when the incomplete insertion position is present. When the through hole 35 is formed and the bottom plate 30 is pushed to the fully inserted position where the distal end 30a in the insertion direction contacts the innermost end 12a of the recessed portion 12, the through holes 35 are The bottom wall 14 is set so as to be completely out of the through hole 15, particularly between the through holes 15, 15 or between the innermost through hole 15 and the innermost end 12 a. . More preferably, as shown in the figure, each through hole 35 of the bottom plate 30 is located between the through holes 15 and 15 of the bottom wall 14 and between the deepest through hole 15 and the innermost end 12a. It is set to be located at the center position. B in the figure indicates the distance between the complete insertion position and the incomplete insertion position.

  The through hole 15 in the bottom wall 14 and the through hole 35 in the bottom plate 30 are not limited to a planar circular hole as shown in the figure, but a planar elliptical or rectangular hole or other irregularly shaped hole is formed in the width direction. They can be formed in parallel, or long holes or slit-like holes in the width direction or oblique direction can be formed. Also in this case, the diameter d in the description of the arrangement of the through holes 15 and 35 is set as a passing dimension such as a width in the bottom plate insertion direction of the through hole, and the range of the distance L between the through holes is not less than the passing dimension. The position where the predetermined dimension is pulled out can be set as the incomplete insertion position and formed so as to have the same arrangement as described above.

  The passing dimensions such as the diameter d of the through-holes 15 and 35, the number of arrangement thereof, the opening ratio, etc. can be appropriately set in consideration of the effect of discharging the liquid when slurry ice is charged and charged and the effect of preventing ice from entering, For example, the passing dimension of the diameter d is in the range of 2 to 30 mm, but of course the dimension can be outside the range. Reference numeral 31 in the figure denotes a notch for handling.

  As a structure for positioning the bottom plate 30 at the complete insertion position and the incomplete insertion position, a required portion of the contact surface in the insertion direction between the bottom plate 30 and the recessed portion 12, for example, a ridge 33 When the bottom plate 30 is in the fully-inserted position, it is fitted to a required portion of both side end surfaces having a fitting structure with the recess 13 and / or the surface of the bottom wall 14 and the surface of the bottom plate 30 opposite thereto. A plurality of concave and convex fitting means are provided, and at least one concave and convex part of the fitting means are fitted when the bottom plate is in the incomplete insertion position. It has been.

  In the first embodiment shown in FIGS. 1 to 11, an interval corresponding to the distance b between the completely inserted position and the incompletely inserted position is provided at both end faces near the distal end 30 a in the inserting direction of the bottom plate 30. A pair of recesses 36 each having a groove shape in the thickness direction of the bottom plate are provided, and on the other hand, the bottom plate 30 is in a completely inserted position on both side end surfaces in the vicinity of the innermost end 12a of the recessed portion 12. In some cases, a pair of rib-shaped convex portions 16 that fit into the two concave portions 36 are formed, and one convex portion 16 has one concave portion in a state in which the bottom plate 30 is pulled out to an incompletely inserted position. 36 to be fitted. Thus, the bottom plate 30 can be positioned at a predetermined complete insertion position and an incomplete insertion position.

  Further, concave portions 37 having a groove shape in the thickness direction of the bottom plate are provided at locations on both side end surfaces in the vicinity of the drawer side end portion 30b of the bottom plate 30, and on the other hand, both sides in the vicinity of the open side end of the concave portion 12 are provided. A rib-like convex portion 17 that fits into the concave portion 37 when the bottom plate 30 is in the fully inserted position is provided at the end face, and the bottom plate 30 in the fully inserted position is positioned with good stability. It can be held.

  In the case of the embodiment of FIGS. 1 to 11, as the fitting means on the contact surface in the insertion direction of the bottom plate 30 and the recessed portion 12, the bottom wall surface in the vicinity of the open side of the recessed portion 12, that is, On the lower surface of the bottom wall 14, two groove-shaped recesses 18a, 18b in the width direction are provided at an interval corresponding to the distance b between the complete insertion position and the incomplete insertion position, while the bottom plate When the bottom plate 30 is in the fully inserted position, the bottom plate 30 is fitted to the inward recess 18a on the surface, that is, the upper surface, which is opposite to the bottom wall surface in the vicinity of the end portion 30b on the drawer side 30.

In addition, the bottom plate 30 can be stably held at the position where the bottom plate 30 is pushed into the fully inserted position.

  Note that the convex portion 16, the convex portion 17, and the convex portion 38 are all high enough to allow the bottom plate 30 to be pushed to the fully inserted position using the elasticity of the foamed resin of the constituent material. The surface is mainly formed into a convex shape having a circular arc cross section or a triangular mountain shape.

  In the state where the bottom plate 30 is pushed into the recessed portion 12 in the fully inserted position, the upper surface of the bottom plate 30 is in contact with the lower surface of the bottom wall 14, so that a certain degree of airtightness can be maintained. In the case of the illustrated embodiment, the peripheral portion of the through hole 35 on the upper surface of the bottom plate 30 relative to the surface of the bottom wall 14 is formed with a slight thickness increase (for example, about 0.5 mm), Thereby, the contact pressure with respect to the lower surface of the said bottom wall 14 can be increased rather than another part. That is, it is possible to prevent the water leached between the bottom wall 14 and the bottom plate 30 from flowing through the through hole 15 into the portion of the through hole 35 of the bottom plate 30 at the contact portion by the thickened portion 39 around the through hole. Thus, water leakage from the through hole 15 and the through hole 35 can be prevented.

  Further, in order to increase the contact pressure between the bottom plate 30 and the bottom wall 14 in a state where the bottom plate 30 is pushed into the fully inserted position with respect to the recessed portion 12, as shown in FIG. The innermost end portion 13a of the recess 13 on both side end surfaces of the installation portion 12 is formed to be slightly inclined upward, so that the protrusion 33 on both end surfaces is fitted to the recess 13. The bottom plate 30 to be inserted is brought into strong contact with the bottom wall 14 by being slightly displaced upward along the end portion 13a of the recess 13 in a state where the bottom plate 30 is pushed into the complete insertion position. .

  Furthermore, in the case of the physical distribution container A of the embodiment of FIGS. 1 to 11, a required portion of the side wall of the container main body 10, for example, a portion of the corner portion 21 in the side wall of both side regions 11 b of the bottom portion 11 corresponds to this. Vertical holes 22 and 42 penetrating in the vertical direction are provided at the peripheral portion of the lid 40, for example, at the four corners 41, and as shown in an enlarged view in FIG. 11, the periphery of the bottom 11 of the container body 10 A recess 23 dropped from the upper surface of the bottom 11 and a drainage passage 25 by a lateral hole 24 extending from the recess 23 to the longitudinal hole 22 are provided at a location near the longitudinal hole 22 of the bottom portion 11. On the side of the vertical hole 22, a trap portion 27 is provided that is higher than the inner end upper wall portion 26 of the horizontal hole 24.

  As a result, the water generated by melting the ice stored during use of the container can be discharged from the drainage passage 25, and at the normal time, a good sealing property can be secured by the water accumulated in the recess 23. . In particular, the lid body 40 is also formed with a vertical hole 42 communicating with the vertical hole 22 of the container body 10, so that even in a state where a plurality of physical distribution containers A are stacked (chain lines in FIG. 10), Water can be discharged through the vertical holes 22 and 42 of the distribution container A.

  FIGS. 12-18 has shown the 2nd Example of the physical distribution container A of this invention. In this embodiment, the basic configuration modes of the foamed resin container body 10, the lid 40, the bottom plate 30, and the like are the same as those in the first embodiment, so that the same configuration and functions are achieved.
