[Conventional technology]

Conventionally, in a container made of a foam synthetic resin container body and a lid body, in which the lid body is rotatably and freely attached to the container body, one side when the both lids are closed Stick tape over or mold integrally with the container body with the lid open, and while hot, push the member with the V-shaped tip at the boundary between the two as shown in Fig. 6. There is one in which a hinge portion for bending a thin film is provided at the boundary between the two.

[Problems to be solved by the device]

However, in order to attach the lid body to the container body in such a manner that the tape can be attached to the container body in such a manner that the tape body can be pivotally and freely opened, the lid body is once placed on the container body, and the tape cut into a required length is roughly attached. After sticking it over the container body and lid at the desired site, or after cutting the tape to the required length,
Similarly, it is necessary to attach it across the container body and the lid at a desired portion. For this reason, not only is it time-consuming to work, but the container body and lid are only joined together via a tape, so there is a problem of tape peeling and it is not suitable for repeated use. However, there is a problem that it cannot be used stably for a long period of time. In addition, if the hinge part is provided after the container body and the lid are integrally molded, the mold may be complicated or upsized, and further, the thin film hinge part is likely to be damaged. Also, there is a problem that it cannot be used stably for a long period of time.

In view of such conventional problems, the foam synthetic resin container according to the present invention has been made, and the lid can be easily attached to the container body so as to be rotatable and open. The purpose is to enable stable use over a period of time.

〔Example〕

The details of the foamed synthetic resin container according to the present invention will be further described with reference to the accompanying drawings.

An example of such a container is shown in FIG. 1 and FIG. 2. In this figure, 1 is a box-shaped container body made of foamed synthetic resin and having an open upper surface, which is a box-shaped container body. Shown is a plate-like lid made of the same foam synthetic resin that closes the upper opening of the container body 1. Further, in this container, since the lid body 2 is attached to the container body 1 so as to be rotatable and open, a shaft portion 3 serving as a rotation fulcrum is integrally provided on the lid body 2 side, and the shaft portion is provided on the container body 1. A shaft support port 4 is provided which allows the lid body 2 to be pivotally operated by rotatably supporting the interior of the lid body 3. The shaft portion 3 has a plate-shaped neck portion 5 formed in a required length at substantially the center of one long side of the outer peripheral edge which is a joint portion of the lid body 2 with the container body 1 when the lid is closed. It is formed into a cylindrical shape having substantially the same length and an outer diameter larger than its thickness, and is formed integrally with the neck portion 5 from the lid body 2. Further, when the lid is closed on one long side facing the shaft portion 3 of the lid 2 at the upper end of the side wall 6 serving as a joint portion with the lid 2 of the container body 1, the lid body is attached to the upper end of the sidewall 6 of the container body 1. In a depth relation in which the outer peripheral edge of 2 is in a state of being laid up, the shaft support port 4 having a circular cross section for rotatably internally supporting the shaft portion 3 is almost the same as or longer than the length of the shaft portion 3, Moreover, the inner diameter thereof is substantially the same as or larger than the outer diameter of the shaft portion 3 and is provided on the joint side in an open state through the communication port 7 having a width narrower than the inner diameter. Then, the container body 1 provided with the shaft support port 4
In order to allow the lid body 2 to be opened over the entire length of the upper end of the side wall 6 on the long side of the neck portion, a portion corresponding to the back of the neck portion 5 is opened to the rear side thereof and the joint side of the container body 1 and the lid body 2. As shown in the drawing, the rotation guide recess 8 of the lid body 2 is provided by notching the inclined surface 9 as shown in the drawing. Here, this inclined surface 9 is the lid 2
When increasing the opening angle of, increase the gradient,
Also, when the opening angle is made smaller, the gradient is made smaller. Further, even if the slope is not changed, the whole portion of the lid 2 protruding from the neck 5 as shown by the alternate long and short dash line in FIG. It is possible to adjust the opening angle of the lid body 2.

Then, in such a container, the shaft portion 3 provided on the lid body 2 side is fitted into the shaft support port 4 provided on the container body 1 side to rotate the lid body 2 on the container body 1 as follows. It is installed freely. First, the shaft portion 3 is applied to the communication port 7, and the shaft portion 3 is pressed toward the shaft support port 4. Then, due to the elasticity of the foamed synthetic resin and the shape in which both sides of the communication port 7 are free ends, both sides of the communication port 7 are elastically deformed, and the shaft portion 3 having a diameter larger than the opening width thereof passes. This enables the shaft portion 3 to be introduced into the shaft support port 4 by forced fitting. Then, after the shaft portion 3 is fitted into the shaft support port 4, the shaft portion 3 is locked by the edge of the narrowed communication port 7 to prevent the shaft portion 3 from coming off, and the lid body 2 is repeated. Even if it is opened, there is no danger of it coming off.

In addition to the embodiment shown in FIGS. 1 and 2, FIG.
As shown in (b), a hemispherical convex portion 10 is provided on both sides in the length direction of the shaft portion 3 or on one side (not shown) so that the length of the shaft portion 3 is longer than the length of the neck portion 5. Moreover, a retaining structure 12 is provided in which the convex portion 10 is fitted into a hemispherical concave portion 11 provided on both sides or one side in the length direction facing the shaft supporting port 4 and the shaft portion 3 and the shaft supporting port 4. It can also be formed between. As the retaining structure 12, a hemispherical convex portion 10 provided on one of the end portions of the shaft portion 3 or the shaft support 4 in the length direction.
It is also possible to use the one that is elastically deformed without providing the concave portion 11 on the other side. Alternatively, the retaining structure 12 may be provided by roughening one or both of the ends of the shaft portion 3 or the shaft support 4 in the longitudinal direction.

Further, the rotation guide recess 8 for allowing the lid 2 to be opened is also formed on the inclined surface 9 as shown in FIGS. 1 and 2, and as shown in FIG. It is also possible to form the stepped surface 13 that is stepped down from the joint portion of the first lid 2 with the lid 2. The rotation guide recess 8 may be formed so as to partially cover not only the back of the neck 5 but also the back of the shaft support port 4 as shown in FIG.

In addition, as shown in FIG. 5, it is possible to provide the shaft portion 3 and the neck portion 5 on the container body 1 side and the shaft support port 4 and the communication port 7 on the lid body 2 side.

Further, the shaft support port 4 and the communication port 7 are provided so as to be opened on the outer surface of the side wall 6 of the container body 1 and the side end of the lid body 2, and the shaft portion 3 and the neck portion 5 are slid from the opening end to move the shaft portion 3 It is also possible to fit it in the shaft support port.

Further, it is possible to provide two or more shafts 3 and necks 5.

Further, the container body 1 or the lid 2 as a whole or a part thereof may be formed such that one of the shaft portion 3 and the shaft support port 4 forming portion has a hard foam density and the other has a soft foam density. By doing so, the shaft portion 3 and the shaft support port 4 are less likely to be worn even if the lid body 2 is frequently rotated, and stable use can be achieved for a long period of time.

[Effect of device]

In the airtight container according to the present invention as described above, the shaft portion provided through the neck on one of the joints when the container body and the lid are opened is connected to the shaft support port provided on the other. The lid can be attached to the container body so as to be rotatable and open by forcibly fitting or slidingly fitting through, and the attaching work becomes easy. In addition, since the rotation opening operation of the lid is supported by the shaft portion installed in the shaft support port, it can be used stably for a long period of time.

Furthermore, since the container body and the lid can be molded separately, the mold does not become complicated or large.
