Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a fish box, and more particularly to the structure of a fish box made of foamed resin that can maintain the freshness of fish well.

(Conventional example) Fish boxes made of foamed resin are widely used. However, this type of foamed resin also has poor fusion between powders during foaming, which creates communication holes between the inside and outside, making it easy for air to circulate inside and outside, resulting in poor insulation properties, which makes it easy for the ice inside to melt. In addition, there were other problems such as melted water leaking outside, reducing the freshness of the stored fish, and making the surface of the fish apt to become crusty. In addition, since the surface of this type of foamed resin is porous and rough, fish meat and fish blood can easily penetrate into the interior and attract odors and dirt, and such odors and dirt cannot be completely removed even with careful cleaning. It was something I couldn't do. For this reason, these seed fish boxes tend to be discarded after one use rather than being used many times, resulting in extremely high fish box costs.

(Purpose of the invention) This invention is a foamed resin fish that has insulation properties to prevent ice from melting, and also prevents melted ice from leaking out of the box to keep fish fresh for a long time. The primary purpose is to provide boxes. A second object of the present invention is to provide a fish box made of foamed resin, which is resistant to fish odor and dirt and can be easily cleaned and used many times even if it is contaminated with fish odor and dirt.

(Summary of the invention) The present invention attaches a synthetic resin film to the inner wall surface of a bottomed cylindrical box made of foamed resin, and attaches the upper end of the synthetic resin film to the box, excluding the side ends. It is connected to the upper end surface of. With this configuration, the internal and external communication holes that are created when the box is molded and foamed are shielded with a synthetic resin film, ensuring insulation and making it difficult for ice to melt, while also preventing melted water from leaking out of the box. This prevents the fish from becoming dry, keeping the fish fresh for a long time, and preventing the surface of the fish from becoming dry. In addition, by attaching a synthetic resin film, it is difficult for fish odor and dirt to adhere, and even if these adhere, it can be easily washed and removed. By not adhering to the end face, air between the film and the wall inside the box can be removed.
so that it can easily escape from the side end to the outside,
This makes it easier to store fish.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a fish box 1 according to the present invention being assembled, and FIG. 2 is a perspective view, in which 2 is a bottomed cylindrical box made of foamed resin, and 3 is the inside of the box 2. It is a box-shaped synthetic resin film that is inserted into a container and attached to its inner wall. A notch 4 is formed at the upper corner of the film 3, and the upper end 3a of the film 3 can be bent freely. Reference numeral 7 denotes an adhesive applied to a portion of the upper end 3a excluding the side end 31a. The film 3 is inserted into the box 2, its upper end 3a is bent outward and brought into contact with the upper end surface 2a of the box 2, and is bonded by pressing the hot plate 5 onto it. be done. This heating plate 5 is formed by incorporating heating wires 6 inside the iron plate. When the hot plate 5 is pressed against the upper end 3a, the foamed resin undergoes secondary foaming and becomes a rough surface with unevenness (see the enlarged view of the part in Figure 3). The portion 3a is firmly adhered to the upper end surface 2a. In this way, the film 3 has only its upper end 3a connected to the upper end surface 2a of the box body 2.
By adhering it to the inner wall of the box body 2, it can be easily attached to the inner wall surface of the box body 2 with good workability.

Since the fish box 1 formed as described above has the film 3 attached to its inner wall surface, the internal and external communication holes that were created due to poor fusion between the powder during molding and foaming of the box body 2 are covered with the film. completely shielded by 3,
Therefore, insulation and water leakage prevention properties are completely ensured. Furthermore, by attaching the film 3, fish odor and dirt are difficult to adhere to, and even if they do adhere, they can be easily washed away. Further, in order to simplify the formation of the fish box 1, the film 3 only has its upper end 3a attached to the box body 2.
The film 3 is bonded to the upper end surface 2a, and therefore air tends to enter the space T between the inner wall surface of the box body 2 and the film 3, but such air easily escapes from the side end 31a to which it is not bonded. Can be leaked (second
(See arrows in Figures and Figure 3).

(Effects of the invention) As explained above, the fish box according to the invention has a synthetic resin film 3 attached to the inner wall surface of the box body 2 made of foamed resin and having a cylindrical shape with a bottom.
a is adhered to the upper end surface 2a of the box body 2 except for the side ends 31a, so that the internal and external communication holes created during molding and foaming of the box body 2 are completely shielded by the film 3, and therefore Because it has excellent insulation properties, ice does not easily melt, and melted water does not leak outside, allowing the fish to stay fresh for a long time and preventing the surface of the fish from becoming crusty. Also film 3
By attaching it, fish odors and dirt are less likely to adhere, and even if they do adhere, they can be easily cleaned and removed. Furthermore, since only the upper end 3a of the film 3 is adhered to the upper end surface 2a of the box body 2, the film 3
is easy to install inside the box body 2, and even if air enters the space T created by doing so, it can easily flow out from the non-adhesive side end 31a, making it easy to store fish. It has various effects such as ease of use.
