Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing lid for a container placed on a container and capable of easily switching between a closed state and an open state, and a container provided with the opening / closing lid.

[0002]

2. Description of the Related Art For example, like an oden insulated container for over-the-counter sales, an oden seed and soup are stored on an insulated container.
2. Description of the Related Art A container is known in which a lid member having a peripheral side wall is placed, and a store clerk or a customer sells a product while freely opening and closing the lid. The lid, which is independent of the peripheral side wall, requires a space around the lid to temporarily put the lid when opened. Desired.

[0003] As a structure of such a container lid, Japanese Utility Model Publication No. 59-1970 discloses a special hinge structure, which allows the container to be fully opened without leaning the lid against a surrounding wall or the like. In addition, there is described that the lid body can be self-standingly held in a stable posture when almost fully opened.

[0004]

However, the above-mentioned opening / closing lid structure basically requires the restoring force of the elastically deformed member.
This is to maintain the posture of the lid body, and there is a disadvantage that the hinge portion is liable to crack or break when an uneven load is applied when the lid is opened and closed. Further, there is also a disadvantage that the structure of the hinge portion is complicated and manufacturing is not easy. Furthermore, the lid body is a single piece, and requires a large space upward when released, and a person who intends to open the lid before opening the lid fully needs to operate the lid for a long distance with the tip of the lid. . Further, it is not easy to separate the lid main body from the container side, and in some cases, the hinge may be broken at the time of separation.

An object of the present invention is to eliminate the above-mentioned disadvantages in a container opening / closing lid in which a peripheral side wall and a top plate as a lid main body are not freely separated.
More specifically, for a container that has a configuration in which the top plate, which is the lid body, can be held upright when fully opened, has a simple configuration, is easy to open and close, and is not easily broken, and is easy to manufacture. And a container provided with such an opening / closing lid. Another object of the present invention is to provide an opening / closing lid for a container, which requires a small space for opening and closing the top plate, and which is extremely easy to open and close, and a container provided with such an opening / closing lid. It is in.

[0006]

According to the present invention, there is provided an opening / closing lid for a container, which comprises a peripheral side wall placed on a container, and one side end of the peripheral side wall. It consists of a top plate that can be opened and closed freely with the side as a pivot point, and the top plate is divided into two and connected so that it can be folded in the middle by hinges,
When fully opened, the top plate can stand up and bend in the middle, and can maintain that posture on the pivot point side.

In this opening / closing lid, the top plate, which is the lid body, is composed of two members connected so as to be able to be folded in half, so that the upper space required when fully opened is only required to be half of the total length of the top plate. It is particularly effective as an opening / closing lid for a container mainly used in a limited space such as a container for over-the-counter sales. Further, when the top plate is opened, the top plate may be rotated by holding a portion near the pivot point side of the top plate in a hand, so that a store clerk or a customer needs less operation when opening the top plate. Further, since the self-posture is held at the pivot point side position in the folded state, the posture holding state is stabilized, and there is no unexpected closing due to disturbance.

In a preferred embodiment, the top plate is pivotally supported on the peripheral side wall so as to be detachable therefrom. In this embodiment, for example, when the top plate becomes dirty, it can be easily removed and washed, which is extremely effective in the case of a food insulation container sold in stores. In another preferred aspect, the two-piece top plate is composed of a frame and a transparent plate detachably attached to the frame. In this case, it is possible to check the articles stored in the container with the top plate closed, which is similarly effective in the case of a heat-insulating container for over-the-counter sales. In addition, when the transparent plate becomes opaque due to scratches or dirt, it is possible to return to the original state by replacing only the transparent plate with a new one without replacing the entire openable lid, which can reduce cost Becomes The transparent plate alone can be taken out and washed.

In addition, by using a transparent plate, it is possible to store not only a lid for an oden heat insulating container but also a product which is desirably stored in a high-temperature and high-humidity environment, such as food such as anman, meat and shumamai. As the lid of the thermal insulation container when displaying and selling, the opening / closing lid for the container according to the present invention can be effectively used.

[0010] In a preferred embodiment, the top plate has a pivot shaft and a guide rod at one end, and a peripheral side wall has a bearing hole for accommodating the pivot shaft of the top plate, and the guide rod slides. And an arc-shaped guide groove having the bearing hole as a center point. One end of the guide groove is located slightly behind a vertical plane including the bearing hole, and the guide rod is provided. Abuts against the one end of the arc-shaped guide groove so that the top plate can stand up and hold the posture in a bent state.
According to this aspect, the folded top plate can stably hold its own posture in a state of being slightly inclined backward.
Therefore, it is possible to reliably prevent the top plate from moving in the closing direction due to unexpected disturbance.

The present invention also provides a container provided with the above-mentioned opening / closing lid. Such a container is effective for use as a container for merchandise sales at stores, due to the characteristics of the above-mentioned opening / closing lid.

As described above, in the lid 100, the top plate 50 can be attached to and detached from the peripheral side wall 10 in a state where the top plate 50 is folded in half (center folded). This is advantageous in both handling and operability. Moreover, in the upper space where the opening and closing of the top plate 50 is narrow,
There is also an advantage that the movement can be performed with a small moving amount.

In this embodiment, openings 12d and 14d as ventilation holes are formed in the peripheral side wall 10, and the top plate 50
Also, a vent formed of semicircular notches 53 is formed in the center of the hole. Therefore, this opening / closing lid 100
Is particularly suitable for use as an opening / closing lid for a container under conditions where a large amount of water vapor is generated, such as the Oden heat retaining container 1 shown in FIG. In that case, it is preferable that the food (oden) inside the container can be seen through from the outside. for that reason,
The peripheral wall 10 and the top plate 50 are preferably made of a transparent resin material such as polycarbonate or heat-resistant polymethyl methacrylate. However, for example, when used as a lid of a heat insulation container for oden, the inner surface of the opening / closing lid 100, particularly the inner surface of the top plate 50, tends to become dirty due to steam or the fat or oil of food. In this opening / closing lid 100, the top plate 50 can be easily removed from the peripheral side wall 10, so that cleaning is easy.

Further, the top plate 50 is such that the transparent plate 70 is
1, and it is also possible to remove and clean only the transparent plate 70 as shown in FIG.

The above description is a preferred embodiment of the opening / closing lid for a container and the container provided with the opening / closing lid according to the present invention, and there are many other modifications. The upper edges of the left and right side plates are mountain-shaped in order to promote the drop of moisture condensed on the back surface, and the upper edges of the left and right side plates may be flat depending on the use environment. In some cases, the holes 53 and 12d for venting the vapor formed in the top plate 20 and the peripheral side wall are unnecessary. The top plate 20 is composed of a frame 51 and a transparent plate 70 inserted therein.
It is not indispensable to configure it with another member, and it may be formed as an integral member.
