Description

  TECHNICAL FIELD The present invention relates to a foamed resin container for storing and transporting marine products such as live fish alive while air is blown from an air pump in a container filled with water, and a method for containing live fish.

  In order to transport live fish or the like in a foamed resin container, a technique of transporting live fish or the like housed in water filled in the foamed resin container while supplying air with an air pump has been widely used. For example, Patent Document 1 discloses a method of putting live fish into a hibernating state. However, in this document, an air pump is housed to prevent water from entering, so that the outside of a foam container that houses live fish or the like is contained. In addition, a pocket-shaped accommodation portion is separately formed of the same foamed resin material, and a structure is formed in which a drainage is made by making a hole in the lower portion of the accommodation portion. This is because it is essential to prevent the air pump from shutting down due to water immersion. If the air pump stops, it will immediately lead to the killing of live fish.

  Furthermore, as described above, even if the air pump housing portion is provided outside the foam container, the bubbles of air sent out from the air pump will flow backward to reach the air pump housing portion and prevent the air pump from being damaged. For this purpose, a complicated measure as disclosed in Patent Document 2 is required.

Patent Document 3 discloses a container provided with a placing step portion for installing a pump case having a size over the entire length of the short side wall at a certain position on the container side wall. Furthermore, this long and large pump case has a complicated structure partitioned into a pump arrangement chamber and a hose chamber by a partition wall.

  As described above, in conventional transport containers for live fish, etc., when transporting live fish containers, water and bubbles generated by the air pump enter the storage area of the air pump to prevent the air pump from operating. Therefore, various complicated measures have been taken. However, since it is essential to handle a large amount of water in containers for live fish, it is important to prevent water from entering during transportation. Obviously, it is an important matter. From such a current situation, conventionally, there has been a restriction that the air pump must be set and closed only after all the live fish storage operations have been completed, that is, after the need for water injection or the like has been eliminated.

  The present invention is for solving the above-described problems and has the following configuration.

  That is, the first of the present invention is a foamed resin container provided with an air pump storage part, wherein the container main body cover part corresponding to the container main body part and the air pump cover part corresponding to the air pump storage part are separated, and the air pump The present invention relates to a foamed resin container that can be opened and closed independently of the opening and closing of a container body lid.

As a preferred embodiment,
(1) A partition wall that partitions the container main body portion and the air pump storage portion and a side wall that forms the air pump storage portion are set at a higher position than a side wall that forms the other container main body portion.
(2) A vertically penetrating drainage hole is provided at the intersection of the partition wall that partitions the air pump storage part and the side wall that forms the air pump storage part.
The present invention relates to the foamed resin container described above.

  In the second aspect of the present invention, the container body lid portion corresponding to the container body portion and the air pump lid portion corresponding to the air pump housing portion are separated, the air pump housing portion housing the air pump is closed, and then the container body portion is placed in the container body portion. The present invention relates to a live fish accommodation method characterized by containing water and live fish and then closing a container main body.

  Since the invasion of water can be prevented with a very simple configuration, the air pump can be accommodated in the air pump accommodating portion prior to the operation of accommodating live fish or the like. That is, since the air pump housing part can be closed using the air pump lid part completely separately from the closure of the container main body, after the air pump is set, the live work such as live fish can be efficiently carried out without fear of flooding. Can do. Furthermore, the partitioning of the air pump housing part or the partition walls and side walls to be formed are made higher than the other side walls, thereby making it possible to more reliably prevent water from entering the air pump housing part.

  Further, in the present invention, the air pump lid part is molded integrally with the container body lid part, and can be used by being separated from the container body lid part at the time of use. It is very reasonable for storage and transportation.

  The foaming resin constituting the foamed resin container comprising the container main body and the lid of the present invention includes a foaming agent such as polystyrene resin such as polystyrene, polyolefin resin such as polyethylene and polypropylene, and synthetic resin such as polyurethane resin such as polyurethane. Is impregnated and press-fitted to give foaming properties and foamed. Among them, expanded polystyrene is preferably used from the viewpoint of characteristics and cost.

  In addition, the air pump of the present invention refers to an air pump that is driven by a battery or the like and is generally commercially available for blowing air into a water tank or the like. What is necessary is just to select from commercially available goods suitably according to the blowing capacity | capacitance of air or blowing time. And, using such an air pump, in order to transport the fish and shellfish alive, fresh water, salt-containing water, sea water, etc. that exist in the container body (hereinafter, in the present invention, any one is simply (Expressed as “water”) and blow air into the water.

  Air pumps are not waterproof in most cases because of their price and performance, so if the air pump is directly splashed with water or if it is submerged, the pump will stop and air will stop blowing, and live fish will die. Fall into the result. Accordingly, in the present invention, a lid portion for setting the air pump in an air pump housing portion provided at an appropriate position of the container body and closing the air pump housing portion (in the present invention, it may be simply referred to as an air pump lid portion). ) Can be used to close the air pump storage section. By doing so, even if water is poured into the container body other than the air pump housing part or live fish is stored, the air pump set in the air pump housing part may be watered or submerged. There is no damage to the air pump. In the present invention, the air pump lid portion for closing the air pump housing portion is formed integrally with a lid portion for closing the container body portion (in the present invention, it may be simply referred to as a container body lid portion). It is characterized in that it can be used separately from the container main body lid portion when it is used. By adopting this structure, not only there is no risk of loss or the like, but also molding is easy and it is very rational for storage and transportation.

  Furthermore, in the present invention, the air pump housing part is closed by designing the partition wall that partitions the container main body part and the air pump housing part and the side wall that forms the air pump housing part higher than the side wall that forms the other container body part. After that, even if water is poured into the container main body, it is possible to efficiently prevent water from entering the air pump housing portion, which is an extremely effective mode.

  The foamed resin container of the present invention is mainly used for transporting live fish, but the contents accommodated in the container, that is, the transported object, are not necessarily limited to fish such as live fish, shrimp, It can be widely used for shellfish such as salmon, shellfish such as salmon and turban shell, other seafood that can be transported alive, seaweed, and other seafood products that require transport while maintaining freshness. .

Further, the side wall upper end surface 5 is partially provided with ridges 8 and partly recessed ridges 9, while the corresponding lid lower end surface 7 is partially provided with ridges 9 and partially ridges 8. It is good also as a structure mutually fitted by providing. In any case, it is possible to have a known shape. And it is preferable that the fitting structure is solid enough that the water used after pouring is not leaked out of the container after the lid is closed, and more preferably that the lid is not opened due to impact during transportation. . However, even if the fitting is loose, there is no particular limitation because it can be reinforced with an adhesive tape or the like.

  In FIG. 1, an example is shown in which the air pump storage unit 20 is provided with a partition wall 3 ′ in the side wall 3 of the container body 2 and fits in the side wall 3 of the container body 2. Of course, it may be provided adjacent to the outside of the side wall 3 of the container body 2.

  2 is formed of a container body lid portion 11 that closes the container body 2 and an air pump lid portion 12 that closes the air pump storage portion 20. And it is preferable from the point of the convenience at the time of loss, transportation, and storage that the container main body cover part 11 and the air pump cover part 12 are integrally formed, for example by providing the connection part 15 partially. Any known structure and number of connecting portions 15 can be adopted, and an optimal one can be selected as appropriate.

  As shown in FIGS. 1 to 3, the ridge 8 ′ provided on the lower end surface 7 ′ of the air pump lid portion 12 is fitted into the opening 21 of the air pump storage portion 20. The lid is closed to prevent water from entering the air pump storage unit 20.

  The air hose extending from the air pump housed in the air pump housing portion 20 is inserted into the container body 2 from the recess 35 of the upper end surface 5 ′ of the partition wall 3 ′ through the recess 25 provided in the upper end surface 5 of the side wall 3B. Become. Of the recess 9 provided on the upper end surface 5 of the side wall 3 and the recess 9 'provided on the upper end surface 5' of the partition wall 3 'in order to fit the container body 2 and the container body lid portion 11, the recess At the intersection of 9 'and the groove 9, a notch 33 is provided by extending the groove 9' as it is and notching the side wall upper end surface 5. The notch 33 also serves to drain water without staying when the water in the container body 2 overflows into the recess 9 'provided on the upper end surface 5' of the partition wall 3 'due to vibration during transportation. Become. FIG. 4 is a plan view of FIG. 1 showing the above structure. In addition, although an air hose raises the bottom wall 4 of the container main body 2, 37 is a protrusion for attaching an air hose.

  As another embodiment of the present invention, in FIG. 5, a part 5 ″ on the inner peripheral side of the upper end surface 5 of the side wall 3 </ b> B forming the air pump storage part 20 and the partition wall 3 that partitions the container main body part and the air pump storage part. An example is shown in which a part 5 ′ ″ on the outer peripheral side of the “upper end surface 5 ′” is set higher than the side wall 3 other than the side wall 3B part, that is, the side wall 3A part. FIG. 8 is a partially enlarged perspective view of the air pump storage unit 20 in FIG. 5 and illustrates these structures more easily.

  According to such an aspect, if the air pump is housed in the housing portion 20 and then closed with the air pump lid portion 12, a part 5 ″ of the upper end surface 5 of the side wall 3B portion and the upper end surface 5 of the partition wall 3 ′. Since the position of “part 5” of “is higher than the others, it is more preferable than the embodiment shown in FIG. 1 because water entry is more reliably prevented and better working efficiency is obtained. When carrying out this aspect, as shown in FIG. 7, the depth of the air pump lid 12 in the lid 6 is set shallower by the height of the side wall 3 and the partition wall 3 'of the air pump storage unit 20. Is preferred. If designed in this way, after both the container body lid and the air pump lid are closed, the height of the entire lid 6 of the foamed resin container 1 is such that the container body 2 and the air pump housing 20 Therefore, when the foamed resin containers 1 are laminated in the vertical direction, there is no gap and it is difficult to cause rattling and the like.

  FIG. 9 shows still another embodiment of the present invention. As in FIGS. 5 to 8, the upper end surface 5 of the side wall 3B and the upper end surface 5 ′ of the partition wall 3 ′ are partially 5 ″, 5 ′.

This is an example in which a vertical hole drain hole 45 is provided at the crossing portion. This vertical hole drain hole 45 penetrates the side wall 3 up and down and plays a role of draining the water present in the recess 9 'to the bottom of the container. The structure is represented by the longitudinal sectional view of FIG. When the vertical hole drain hole 45 is provided, the notch 33 can be omitted as shown in FIGS. 9, 11, and 12. However, it is of course possible to have the vertical hole drain hole 45 and the notch 33 coexist. Moreover, in these figures, although the example which provided the two vertical hole drain holes 45 in the two cross | intersection part of the groove 9 'and the groove 9 was shown, one vertical hole drain hole 45 is shown in either cross part. It is also possible to provide it. In this case, it is preferable to provide a notch 33 at the intersection of the groove 9 ′ and the groove 9 where the vertical hole drain hole 45 is not provided.

  Next, a method for accommodating live fish and the like in the foamed resin container using the foamed resin container of the present invention will be briefly described. First, after the air pump is housed in the air pump housing portion 20, the air pump lid portion 12 is separated from the container body lid portion 11, and the air pump housing portion 20 is closed with the separated air pump lid portion 12. As described above, since the air pump is housed in the air pump housing part 20 and closed, the water pumping into the air pump housing part 20 is sufficiently prevented. Next, water, live fish, or the like is stored in the container body 2 as necessary, and then closed with the container body lid portion 11. If you select the concave strip 9 of the container body 2 and the convex strip 8 of the container body lid 12, you can sufficiently prevent the lid from being opened during transportation, but you want to further prevent the lid from being opened during transportation. For this, the contact surface between the container body 2 and the container body lid 11 may be wound with an adhesive tape or the like.

  On the other hand, the air blown out from the air outlet is discharged out of the container by some means. If there is a gap in the fitting portion between the container main body 2 and the container main body lid portion 11, the exhaust may be possible from there. However, when the amount of water to be put into the container body 2 is large and the space with the container body lid portion 11 is narrow, or when water easily foams due to fish species, the fitting portion of the container body 2 and the container body lid portion 11 In the case where the fitting is dense, it is preferable to positively form exhaust means. For example, as shown in FIG. 2, a through hole 40 is provided in the container main body lid 11, and the air filled in the container main body 2 can be discharged. The through-hole 40 is not penetrated from the beginning, and a part thereof is sealed with a foamed resin, which is a raw material. When the through-hole is actually required in use, a rod-shaped one is inserted. It is preferable to let it penetrate. However, it is of course possible to make the through hole 40 having a through hole penetrating from the beginning. When there is water accompanying the air discharged from the through hole 40, the water is removed from the upper surface of the container body lid 11 by the inclined groove 42 connected to the through hole 40.

  In addition to providing such a through hole 40 for exhaust, the upper end surface 5 of the side wall 3 of the container body 2 and the contact surface between the ridges 8 provided on the upper end surface 5 and the lower end surface 7 of the container body lid portion 11. You may discharge | emit through the slit-shaped groove | channel (not shown) provided in this. The slit-shaped groove normally prevents the flow of free air inside and outside the container body 2 due to ventilation resistance. However, if the internal pressure of the container body 2 is increased by blowing air from the air pump, air can flow out. It becomes. This slit-shaped groove has an outer outlet and an inner outlet, and the inner and outer sides of the container body 2 communicate with each other. Then, by appropriately setting the shape, cross-sectional area, length, and the like of the slit-shaped groove, the outer outlet, and the inner outlet, it is possible to promote the bubble breakage accompanying the exhaust air.

  In the present invention, when the vertical hole drain hole 45 is provided, the water flowing down the vertical hole drain hole 45 mainly passes through the through hole 40 or the inclined groove when the through hole 40 is opened from the top of the container body lid 11. It will drain from 42 etc. to the lower part. Further, another embodiment different from the lid body 6 shown in FIG. 6 or the like in which another drainage through hole (not shown) penetrating the lid body 6 is provided at the position of the lid body 6 matching the vertical hole drainage hole 45. By preparing the lid body 6, the container body 2 can be drained. This is preferable because the amount of water transmitted through the side wall 3 is reduced.
