Description

[Technical field]

[0001] The present invention relates to a transport container and a transport method for transporting live sea urchins. [Background technology]

[0002] One possible method for transporting live sea urchins is, for example, placing them in a water tank. However, transporting them in a water tank involves shaking and requires a large tank, making transportation difficult and costly for equipment, etc. As a method for transporting live sea urchins (so-called live sea urchins; hereinafter also referred to as live sea urchins) in a water tank, for example, a water tank facility in which kelp is placed has been disclosed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-030230 A Summary of the Invention [Problem to be solved by the invention]

[0004] On the other hand, if live sea urchins are transported in polystyrene foam like other fresh fish, there is a problem that their spines get stuck in the polystyrene foam and break, weakening and causing death. In addition, they are sometimes transported on sponges to prevent the spines from breaking, but this causes the sea urchins to die from lack of oxygen. Therefore, there has been a demand for the development of a transport container and a transport method that can easily transport live sea urchins.

[0005] The present invention has been made in light of the above problems, and an object of the present invention is to provide a sea urchin transport container and a sea urchin transport method that can easily transport live sea urchins. [Means for solving the problem]

[0006] The sea urchin transport container of the present invention comprises a container and an attachment member arranged corresponding to the inside bottom and sides of the container, made of a plastic member excluding foamed plastic, for attaching live sea urchins.

[0007] The method for transporting sea urchins of the present invention involves placing live sea urchins and seawater or salt water in a sea urchin transport container which comprises a container and an attachment member arranged corresponding to the inside bottom and sides of the container and made of a plastic member excluding foamed plastic, and transporting the live sea urchins by attaching them to the attachment member. Effect of the Invention

[0008] According to the present invention, since the attachment members made of plastic members other than foamed plastic are arranged on the inside bottom and sides of the container, live sea urchins can be attached to the attachment members. This prevents the spines from breaking, and allows the sea urchins to be easily transported alive by filling the container with seawater or salt water, for example.

[0009] Furthermore, by providing a bag-shaped member made of a waterproof sheet between the container and the attachment member, it is possible to prevent leakage of seawater or salt water and also to seal in oxygen. [Brief description of the drawings]

[0010] [Figure 1] 1 is a cross-sectional view showing a configuration of a sea urchin transport container according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0012] FIG. 1 is a cross-sectional view showing the configuration of a sea urchin transport container 10 according to one embodiment of the present invention. The sea urchin transport container 10 has a container 11. The container 11 may be of any type as long as it can store and transport live sea urchins M, but a polystyrene foam container made of polystyrene foam is preferred. This is because it has excellent heat retention and sealing properties. The container 11 includes, for example, a main body 12 having a storage section 11A formed therein and an open top, and a lid 13 that closes this opening. The main body 12 has, for example, a rectangular shape when viewed from above, and has a bottom 12A and four side sections 12B.

[0013] The bottom 12A of the main body 12 is provided with an attachment member 14 made of a plastic material other than foamed plastic. Foamed plastic is a material formed into a foamed or porous shape by finely dispersing gas in a synthetic resin. The attachment member 14 is preferably made of, for example, a plate-shaped member. This allows the live sea urchins M to be attached to the attachment member 14, and for example, it is possible to reduce the possibility of the live sea urchins M rolling and coming into contact with other live sea urchins M during transportation, and it is also possible to prevent the live sea urchins M from directly coming into contact with the container 11, thereby suppressing the live sea urchins M from being weakened and dying due to their thorns being stuck in the container 11. Note that metal or wood members have poor adhesion to the live sea urchins M, and furthermore, the seawater or salt water that is put in together with the live sea urchins M is stained by rust or the like, which is unfavorable to the ecology of the live sea urchins M. In this respect, too, plastic members are preferable because they do not cause problems such as seawater being stained.

[0014] The attachment member 14 may be provided in an area where the live sea urchins M can be attached, but it is preferable that the attachment member 14 is substantially the same size as the entire inside of the bottom portion 12A. This is because it makes it easier to attach the live sea urchins M, and it is possible to prevent the live sea urchins M from moving during transportation, causing their spines to prick the container 11, or to prevent the attachment member 14 from shifting position.

[0015] It is preferable that the attachment member 14 is disposed on the inside of the side portion 12B of the main body portion 12. This is because it is possible to prevent the spines of the live sea urchins M from getting stuck in the side portion 12B, and the live sea urchins M can be attached. The attachment member 14 may be disposed on the entire inside of the side portion 12B, but it is preferable that it is disposed at least to a position higher than the height of the live sea urchins M. For example, the attachment member 14 is preferably configured such that a portion corresponding to the bottom portion 12A of the main body portion 12 and a portion corresponding to the side portion 12B of the main body portion 12 are continuously formed, and the attachment member 14 is disposed to correspond to the bottom portion 12A or the side portion 12B by folding. This is because it is possible to easily cover the inside of the main body portion 12.

[0016] In addition, the height of the attachment member 14 arranged corresponding to the side portion 12B is preferably high, and it is preferable to arrange it corresponding to the entire inside of the side portion 12B. If the amount of seawater or salt water put in together with the live sea urchins M is increased, the live sea urchins M will also adhere to the attachment member 14 on the side, and the amount of live sea urchins M that can be stored can be increased.

[0017] The attachment member 14 may be disposed corresponding to the bottom 12A and the side 12B of the main body 12, and may or may not be provided on the upper part of the main body 12. Fig. 1 shows a case where the attachment member 14 is also provided corresponding to the upper part of the main body 12 (i.e., the lid 13) and configured to cover the upper part of the live sea urchin M.

[0018] The material of the attachment member 14 is not particularly limited as long as it is one to which live sea urchin M can be attached, but for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile-styrene resin (AS), acrylonitrile-butadiene-styrene resin (ABS), polyvinyl chloride (PVC), methacrylic resin (PMMA), polyethylene terephthalate (PET), or polycarbonate (PC) are preferred. Among these, polyethylene, polypropylene, acrylonitrile-styrene resin, or polycarbonate are more preferred because live sea urchin M can be attached more effectively. In particular, polypropylene is more preferred because it has excellent adhesiveness for live sea urchin M and is easy to process.

[0019] Moreover, the attachment member 14 is preferably formed from plastic cardboard, which is lightweight, elastic, and easy to bend, and therefore can be easily processed into a shape that matches the bottom 12A and side 12B of the main body 12, for example.

[0020] It is preferable to provide a bag-shaped member 15 made of a waterproof sheet between the container 11 and the attachment member 14. This is because it is possible to prevent the seawater or salt water from leaking when seawater or salt water is placed in together with the live sea urchins M, and also to seal in oxygen. Examples of the material for the bag-shaped member 15 include vinyl.

[0021] The method for transporting sea urchins according to one embodiment of the present invention can be carried out, for example, by using a sea urchin transport container 10. First, a bag-shaped member 15 is placed in the storage section 11A of the container 11, and an attachment member 14 is placed inside the bag-shaped member 15 so that the attachment member 14 comes into contact with the bottom 12A and the side 12B of the main body 12 via the bag-shaped member 15. Next, live sea urchins M and seawater or salt water are placed inside the attachment member 14, i.e., inside the bag-shaped member 15, so that the live sea urchins M are placed on the attachment member 14. At this time, oxygen may be blown into the seawater. Thereafter, the bag-shaped member 15 is closed, and the main body 12 is closed with the lid 13 and transported. This prevents the spines of the live sea urchins M from breaking, and since they are in seawater or salt water, they are transported alive.

[0022] Thus, according to this embodiment, the attachment member 14 made of a plastic member excluding foamed plastic is arranged in correspondence with the bottom 12A and side 12B inside the container 11, so that the live sea urchins M can be attached to the attachment member 14. This makes it possible to prevent the spines from breaking. Also, since the sea urchins can be transported while still in seawater or salt water, they can be easily transported alive.

[0023] Furthermore, by providing a bag-like member 15 made of a waterproof sheet between the container 11 and the attachment member 14, it is possible to prevent seawater or saline solution from leaking and also to seal in oxygen. EXAMPLES

[0024] (Examples 1-1 to 1-8) An adhesive member 14 was placed inside the container 11 so as to cover the bottom 12A and the four side parts 12B. Next, live sea urchins M and seawater were poured into the container 11 whose inside was covered with the adhesive member 14. One minute after pouring, the container 11 was shaken to confirm that the live sea urchins M were attached, and then the live sea urchins M were grasped with bare hands to confirm whether they could be peeled off. For the adhesive member 14, a polyethylene plate member was used in Example 1-1, a polypropylene plate member was used in Example 1-2, a polystyrene plate member was used in Example 1-3, an acrylonitrile-styrene resin plate member was used in Example 1-4, an acrylonitrile-butadiene-styrene resin plate member was used in Example 1-5, a polyvinyl chloride plate member was used in Example 1-6, a methacrylic resin plate member was used in Example 1-7, and a polyethylene terephthalate plate member was used in Example 1-8. Note that none of the adhesive members 14 used in Examples 1-1 to 1-8 were foamed plastics.

[0025] For Comparative Examples 1-1 to 1-3, except that the adhesive member was changed, the adhesive member was placed inside the container 11 in the same manner as in Examples 1-1 to 1-8, and the adhesiveness of live sea urchins was confirmed. For the adhesive member, a urethane sponge was used in Comparative Example 1-1, a wooden (cedar) plate member was used in Comparative Example 1-2, and a stainless steel plate member was used in Comparative Example 1-3.

[0026] The results of the adhesiveness of live sea urchins M are shown in Table 1. Adhesion was judged as follows: x if the sea urchins did not adhere to the adhesive member 14 and moved when the container 11 was shaken, o if the sea urchins did not come off when the container 11 was shaken but all of the sea urchins could be peeled off from the adhesive member 14 with bare hands, and ◎ if some sea urchins did not come off even when shaken and could not be peeled off even with bare hands.

[0027] [Table 1]

[0028] As shown in Table 1, in Examples 1-1 to 1-8 in which a plastic member other than foamed plastic was used as the adhesive member 14, it was confirmed that live sea urchins M adhered to the adhesive member 14. Among them, it was found that the polyethylene plate member of Example 1-1, the polypropylene plate member of Example 1-2, and the acrylonitrile-styrene resin plate member of Example 1-4 adhered better and were more preferable. In contrast, it was found that the adhesiveness was poor in Comparative Example 1-1 in which a urethane sponge of foamed plastic was used, Comparative Example 1-2 in which a wooden plate member was used, and Comparative Example 1-3 in which a metal plate member was used.

[0029] (Examples 2-1 and 2-2) A bag-shaped member 15 was placed inside the container 11, and an adhesive member 14 was placed inside the bag-shaped member 15 so that the adhesive member 14 was in contact with the bottom 12A and the side 12B of the container 11 via the bag-shaped member 15. A plate-shaped member made of polypropylene, not foamed plastic, was used for the adhesive member 14. Next, live sea urchins M and seawater were placed inside the adhesive member 14, and in Example 2-1, oxygen was blown into the seawater, and in Example 2-2, oxygen was not blown into the bag-shaped member 15 and the bag-shaped member 15 was closed. That is, oxygen was sealed in the bag-shaped member 15 in Example 2-1, and oxygen was not sealed in the bag-shaped member 15 in Example 2-2. After leaving it for two days, the condition of the live sea urchins M was observed. If all individuals had died after two days, the survival was evaluated as ×, if all individuals were alive but weakened such as spines coming off was observed, the survival was evaluated as ◯, and if all individuals were alive and no weakening was observed, the survival was evaluated as ◎. The results are shown in Table 2.

[0030] [Table 2]

[0031] As shown in Table 2, the survival of live sea urchins M was confirmed in each Example. Among them, it was found that the sea urchins M survived in a better condition in Example 2-1 in which oxygen was enclosed, which was more preferable.

[0032] Although the present invention has been described above with reference to the embodiment, the present invention is not limited to the above embodiment and can be modified in various ways. For example, in the above embodiment, each component is specifically described, but it is not necessary to include all components, and other components may be included. Also, the specific configuration of each component is shown as an example, and may be different. [Industrial Applicability]
