Description

[Detailed description of the invention] This invention is a combination of multi-layered boxes suitable for transporting living things that are mainly used as bait for fishing, such as ``fish'', ``blue some'', and ``vipers'', and other items that need to be kept cold. It concerns containers.

When transporting items that need to be kept cold, such as fishing bait, a container is generally provided with a storage section for a cooling medium inside the container. If one is provided for each container, the goods to be transported and the cooling medium must be stored in each container, which makes the work cumbersome. In addition, the reason why one of the stacked containers is used as a storage area for cooling and refrigerating media is that as the number of stacked containers decreases, the ratio of the storage space for cooling and refrigerating media to the overall capacity increases, and the storage efficiency of the objects to be transported decreases. do.

The present invention was developed in view of the above, and includes a storage area for cooling and insulating media by an enclosure wall installed at the bottom inside each stackable container, and a storage area for the loading container that can be stacked on the bottom layer. The bottom of the wall is opened so that the storage parts for the cooling and cold storage medium are connected vertically in a stacked state, so that the cooling and cold storage medium can be easily stored and the cool air can be uniformly distributed throughout each container. It was designed so that

Next, embodiments of the present invention will be described based on the drawings.
10 is a so-called bottom layer container used for the lowest layer; 20 is a loading container that can be stacked on top of the container 10 in a multi-box style; 30 is a lid that can be attached to the loading container 20; It is made of synthetic resin foam. In the case of the figure, a notch step 11 is formed on the outer side of the upper edge of the peripheral wall of the bottom layer container 10 and the loading container 20.
and 21 are provided, and the loading container 2
A projecting edge 22 that fits into the cutout steps 11 and 21 is vertically provided on the bottom periphery of the container 0, so that the containers 10 and 20 can be stacked together in a fitted state, and the lid 30 is attached to the bottom of the 0. The hanging protrusion 31 allows fitting and attachment to the notch step 21 of the loading container 20, and also to the notch step 11 of the bottom layer container 10.

Inside each of the bottom layer container 10 and the loading container 20, there are surrounding walls 13 and 23, each having a cylindrical shape that separates a portion, for example, the center from the other portions of the bottom layer 1.
4 and 24 are erected at corresponding positions, and in particular, the bottom of the enclosure wall 23 of the loading container 20 is cut out to form an opening b.
In the stacked state of 0 and 20, the surrounding walls 13 and 23 are in vertically corresponding positions, and the internal space is from the bottom layer container 10 to the top layer loading container 2.
This enclosure wall 1 is connected vertically to 0.
The internal spaces 3 and 23 are configured as a storage section a for a cooling cold storage medium. In the illustrated embodiment, the bottom surface of the bottom 24 of the loading container 20 is placed within the required area around the opening b as a means for circulating cold air from the storage section a for the cooling and cold storage medium to the outside of the surrounding walls 13 and 23 in each container. A reinforcing convex portion 24' is provided in the concave portion 25 and extends radially outward from the periphery of the opening b.
and the surrounding wall 13 or 23 of the lower layer of the container, and the center portion of the lower surface of the lid 30 is recessed over a wider range than the surrounding wall. The structure is such that a gap is provided between the enclosing wall 23 of the uppermost container 20 and the lid 30 attached thereto, due to the recessed portion 32, and the gap due to the recessed portions 25 and 32 is maintained. Even during storage, cold air can flow through all of the bottom and loading containers 10 and 20. In the above, the loading container 2
It is also possible to provide a concave portion extending radially from the periphery of the opening b on the lower surface of the bottom portion 24 of 0. In addition to the above-mentioned embodiments, the cold air distribution means can be used by forming the surrounding walls 13 and 23 of the bottom layer and loading containers 10, 20 slightly lower than the surrounding walls, and connecting the upper edge of the surrounding walls 13 and 23 to the upper layer of the loading container. Various structures are possible, such as providing a gap between the lower surface of the bottom of the housing 20 and the lower surface of the lid, or providing a notched recess at the upper edge of each of the surrounding walls 13 and 23.

In addition, the bottom layer container 10 and the loading container 2
0 is the bottom part 14 outside the enclosure walls 13 and 23, respectively.
Embankment wall 1 with the top surface of 24 in one or both vertical and horizontal directions
6, 26 are provided protrudingly at required intervals and divided into multiple parts, for example, in a square shape as shown in the figure, and
Small protrusions 18, 28 are scattered in each section 17, 27, and are used as bait for fishing.
It is particularly suitable for transporting. In other words, it is possible to disperse and store "gokai" in which a large number of "gokai" have the property of clumping together in each compartment part 17, 27, and to reduce the "gokai" in the compartment parts 17, 27 from clumping together. Convex portion 18,
This can be prevented by 28. Of course, the embankment wall 1
The partitions 6 and 26 and the small protrusions 18 and 28 are not necessarily necessary if the object to be stored is something other than a "gokai". Furthermore, in the case of the illustrated embodiment, the inside of each container 10 and 20 is divided into left and right parts by partition walls 19 and 29 extending from the front and back of the enclosure walls 13 and 23 to the peripheral wall part, and the inside of each container 10 and 20 is divided into left and right parts. It is designed to prevent objects to be transported, such as "gokai", from shifting to one side or getting into the other during transportation.

The synthetic resin foams that are the constituent materials of the containers 10, 20 and the lid 30 include styrene resin foams such as polystyrene resins and copolymers mainly composed of styrene, polyvinyl chloride resin foams, Polyolefin resin foams and other synthetic resin foams can be used. Further, a skin layer of non-foamed resin may be provided on the surface of the synthetic resin foam.

The present invention is constructed as described above, and is used for transporting fishing bait, such as "gokai".The number of stacked stages (four stacked in the case of the figure) can be determined arbitrarily, but usually five It is used in a six-tier stack of two loading containers 20 and one bottom layer container 10.

When using the container of the present invention, the bottom layer container 10
and internal enclosure walls 13, 2 of each loading container 20.
A predetermined amount of objects to be transported such as a "gokai" is placed in each of the outer parts of 3, and the bottom layer container 10 is placed at the bottom layer, and the loading container 20 is stacked on top of it in a multi-box style. In this stacked state, the respective surrounding walls 13 and 23 are in vertically corresponding positions, and the bottom part of the surrounding wall 23 of each loading container 20 is cut out to form an opening b, and each of these surrounding walls 1
The internal spaces of 3 and 23, that is, the storage area a for the cooling and cold storage medium, are vertically connected from the bottom container 10 to the top layer container 20, so they can be filled with coolant such as dry ice, cold storage material, or other suitable material. The cooling cold storage medium can be introduced into the storage section a from the top and stored therein. Thereafter, a lid 30 is attached to the uppermost container 20, and if necessary, the containers are held in a stacked state by hanging a string such as a band over the entire container or by using an adhesive tape.

In the above stacked state, each container 10, 2
0 enclosure walls 13, 23 and the loading container 20 thereon
Since a means for distributing cold air to the outside of the enclosure wall is provided between the bottom part 24 or the lid body 30 of It flows to the outside of the enclosure walls 13, 23 of each container 10, 20 through the distribution means, and the objects to be transported in all the containers 10, 20 are directly cooled and kept cold. In particular, since the storage section a for the cooling cold storage medium is vertically connected through the opening b in the enclosure wall 23 of the loading container 20, even if the cooling cold storage medium such as dry ice decreases, the cold air will not flow out. Each container 10, 20 rises upward through the opening b and passes through the respective cold air distribution means.
It enters the surrounding walls 13, 23 to the outside, and each container can be equally cooled and kept cold until the end. Furthermore, since the container as a whole is sealed and made of synthetic resin foam with good heat insulation properties, it is possible to maintain a cold state without letting cold air escape.

Furthermore, since the storage section a for the cooling and cold storage medium is configured to communicate vertically as described above, the loading container 20
If the number of stacked stages increases or decreases, the space in the storage section a also increases or decreases accordingly, so it is necessary to always use an appropriate amount of cooling medium in the same proportion to the amount of objects to be transported in the total stacked volume. For example, when the number of stacked stages decreases, the storage space for the cooling and cold storage medium decreases accordingly, and the storage efficiency of the objects to be transported does not deteriorate.

Furthermore, each container 1 has a storage section a for the cooling cold storage medium.

There is no risk that the objects to be transported stored outside the enclosure walls 13, 23 of 20 will enter the storage area a inside the enclosure walls 13, 23, and if the objects to be transported require moisture, such as a "gokai", etc. In this case, moisture in the transported object does not flow into the storage section a, and each container can maintain an appropriate water retention state, and can be well protected.

Furthermore, the container of the present invention is made of synthetic resin foam, is lightweight and easy to handle, greatly increases transportation efficiency, and can be manufactured easily and inexpensively by molding.

As described above, the present invention has a storage section for the cooling medium provided inside each of the containers stacked in multiple stages, which is connected vertically, making it easy to store the cooling medium and making it possible to store the cooling medium inside each container. The cool air is distributed uniformly and evenly until the end.
It can be very suitably used as a container for transporting ``Blue Someme'', ``Viper'', etc., and also as a container for transporting and storing other items that require cold storage.
