DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded container made of a foamed synthetic resin used for a vegetable box, a fish box, and the like, and more particularly to the molded container suitable for pre-cooling in a refrigerator.

[0002]

2. Description of the Related Art Conventionally, foamed synthetic resin containers such as fish boxes and vegetable boxes have been widely used for storing fish and vegetables and storing them in a refrigerator. Therefore, if you check the contents and try to find out the internal state of the contents, you have to open the lid and check the contents. Therefore, a small window is partially provided in a lid or the like in order to visually recognize the contents of the container.

[0003]

However, in the case where the small window is provided in the lid or the like as described above, even if the contents stored in the inside can be visually recognized, the molded container only by opening and closing the lid stores vegetables and the like. To pre-cool in the refrigerator
The lid had to be closed, and even if it was placed in a refrigerator, the effect of cold air circulation in the refrigerator could not be obtained due to the heat insulation property of the molded container, and the loss in refrigeration efficiency was inevitable.

[0004] The present invention addresses the above-mentioned situation and finds a combination of sliding and locking of the lid. It is an object of the present invention to enhance the pre-cooling effect by distribution, improve the refrigeration efficiency, and facilitate the visual recognition of the contents.

[0005]

That is, a feature of the molded container according to the present invention that meets the above-mentioned object is that a rectangular foam synthetic resin having a bottom surface and side walls rising from the outer periphery of the bottom surface and having an open top surface. A container body, and a rectangular lid member for closing the upper surface opening of the container body. The upper surface of one of the opposite side walls of the container body and the opposing surface of the lid member corresponding to the upper surface are fitted to each other. The container has a structure in which a lockable portion is provided, and both sides of the other opposite side wall of the container body and the lid member corresponding to the side wall are provided with a structure capable of sliding with each other.

According to a second aspect of the present invention, the above-mentioned molded container is further improved, and the upper portion of the side wall of the container body, which has a structure capable of engaging and sliding with each other, and the side portions of the lid member with respect to the upper portion. In the joint portion, a ventilation gap for communicating the inside and outside of the container body at a required sliding position is provided at a shifted position.

[0007]

The molded container according to the present invention accommodates fish, vegetables and the like in the refrigeration stage before freezing, releases the locking between the lid member and the container body, and slightly displaces the lid member. First, check the contents and place them in the refrigerator.When the refrigerator is put into the refrigerator, the cool air in the refrigerator flows into the container through the communication gap due to the displacement, bringing the fish, vegetables, etc. contained in the container closer to the refrigeration temperature, before freezing. Pre-cooling is effectively performed.

When the predetermined pre-cooling is completed and the process proceeds to the next step, the container is taken out of the refrigerator, and the mating stoppers are fitted to each other by reversing the displaced portions, and The inside is sealed, and kept in a refrigerated state under heat insulation and transferred to a freezing process or a use stage.

As described above, the contents are confirmed by shifting the lid member, the flow of the cool air into the container is improved, and the effect of promoting the heat insulation effect of the outside by the locking after the removal is exhibited.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 3 show the opening, closing and sliding modes of a molded container according to a first embodiment of the present invention. In these figures, reference numeral 1 denotes a bottom surface and side walls rising from the outer periphery of the bottom surface. And a box-shaped container body 2 made of a foamed synthetic resin such as a square-shaped expanded polystyrene having an open upper surface, a lid member 2 for closing the upper surface opening of the container body 1,
A locking portion that fits and locks the upper surface of one of the two opposite side walls of the container body 1 and the opposing surface of the lid member 2 corresponding to the upper surface. At the left and right sides of the stoppers 5 and 6, locking portions 7 and 8 are provided by means of left and right convex and concave hooks.

Here, the unevenness fitted to each other may be an unevenness extending over the entire length of the side wall, an unevenness having an appropriately short length divided into a plurality of portions, or a plurality of unevenness scattered in spots. Anything can be used as long as it secures the locking between the cover member 1 and the cover member 2 and holds and fixes the inside of the container in a closed state from the outside. Further, the present invention is not limited to the illustrated concave-convex locking, and may be appropriately deformed as long as similar locking and fixing can be obtained.

On the other hand, 3 and 4 are the container body 1 and the lid member 2
On the other side wall different from the side wall on which the locking portions 5, 6, 7, 8 are provided, the container body 1 can slide upward on the container body 1 side, and can slide on the lower or lower inner surface on the lid member 2 side. The sliding member is provided as described above. In the illustrated example, the sliding member is a sliding portion formed by fitting and sliding of the ridge and the groove, and a sliding structure is formed by fitting and sliding of the two.

In the illustrated molded container, the sliding portion does not extend over the entire length of the lid member 2 in the lateral direction on the downward side wall of the lid member 2 and a slight gap a is left at one end. This is because the lid member 3 has a role as a stopper that defines a range when the lid member 3 is slid with respect to the container body 1. The size of the gap a is appropriately selected in consideration of the content confirmation and the effectiveness of the inflow of cool air.

Thus, the vegetables, fish, etc. are stored in the container body 1, completely closed by the lid member, and transported from the site.
Alternatively, when receiving the containers, such as vegetables and fish, which are completely shipped and sent to the site, respectively, when placing the containers in the refrigerator, displacing the cover member 2 within a required range, the contents, and It is confirmed whether it is in such a state. When the refrigerator is placed in the refrigerator with the lid member shifted, the cool air in the refrigerator flows from the shifted gap to cool the contents.

Next, when the pre-cooled fish, vegetables and the like are frozen or taken out of the refrigerator and transported to another place, the shifted state is returned to the original state, and if the locking portion is locked, the heat insulating container is obtained. Cold air is maintained and efficiency is improved.

FIGS. 4 and 5 show a second embodiment of the molded container according to the present invention, which comprises a foamed synthetic resin container main body 1 and a lid member 2 for closing the upper opening of the container main body. A pair of engaging portions 5, 6, 7, which can be fitted to each other on an upper surface of one of the two opposite side walls 1 and an opposing surface of a lid member corresponding to the upper surface;
8 are provided, and structures 3 and 4 that can be engaged with each other and slidable are provided on the upper portion of the opposite side wall of the container body and on both side portions of the lid member corresponding to the upper portion of the side wall. This is the same as in the first embodiment, but in the second embodiment, the sliding member 3 on the upper side wall of the container body 1 and the corresponding sliding members 4 on both sides of the lid member 2 are further provided with a predetermined lid member 2. The air gaps 9 and 10 are provided so as to be shifted from each other so that the inside and outside of the container can be communicated by the sliding when sliding in the range. In this case, the lid member 2 is slid so that the outside of the gap at one end due to the sliding displacement, and furthermore, the ventilation between the inside and the outside of the container body 1 by the communication of the ventilation gaps 9 and 10 between the container body 1 and the lid member 2. The exchange becomes active, and the pre-cooling effect by refrigeration can be further improved.

Although the specific embodiment of the molded container of the present invention has been described above, the present invention is not limited to the above description, and it is needless to say that the present invention can be appropriately modified without departing from the purpose thereof.

[0019]

As described above, according to the present invention, in a molded container comprising a rectangular foamed synthetic resin container body and a lid member, an upper surface of one of both side walls facing the container body and a lid member corresponding to the upper surface. In addition to the above-mentioned structure, a locking portion that can be fitted to each other is provided on the opposite surface of the container body, and a structure that is slidable on both sides of the other opposite side wall of the container body and the lid member corresponding to the side wall is provided. In order to view the contents stored inside only by opening and closing the lid member, the lid must be opened, and for ventilation with the outside, it is necessary to open the lid or provide a window or hole in the lid member, There is a drawback in the heat retention effect, and no one that can simultaneously satisfy the requirements of both the efficient air circulation such as pre-cooling in the refrigerator and the visual recognition of the contents was not found, but the present invention shifts the position by sliding the lid member. Only the contents Since the visual recognition can be easily performed and the cool air can be easily circulated through the gap of the shifted portion as a shifted state, there is a practical effect that can satisfy both of the above requirements at the same time. When it is not displaced, it can be securely locked by the locking portion to sufficiently maintain the heat insulation and heat retention in the container, so that the pre-cooling effect as in the case of pre-cooling in the refrigerator prior to freezing and the effect of promoting the refrigeration efficiency thereafter Is extremely large and has a remarkable advantage as compared with the conventional molding container.
