Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an openable/closable container made of a synthetic resin cabinet whose main body and lid are integrally connected by a hinge and can be opened and closed.

2. Description of the Related Art Containers in which the main body and lid of a cabinet constituting a container are integrally constructed by a hinge portion and can be opened and closed have been used in the past, examples of which are shown in FIGS. 5 and 6. A conventional example will be explained below based on FIGS. 5 and 6.

In the figure, 1 is the cabinet body, 2 is the lid body,
It is integrally formed with a hinge part 3 provided on the negative side thereof, and can be opened and closed by this hinge part 3. And the above body 1
and a side portion 1a of the lid body 2 facing the hinge portion 3;
2a, by forming an engaging part 1b and a locking part 2b and locking them as shown in FIG.
The lid can be closed and maintained in that state. That is, when the lid body 2 is rotated in the direction of the arrow in the state shown in FIG. It can be easily locked by deforming it.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, if the depth of engagement of the locking portion 2b with the engaging portion 1b is made shallow, the locked state may be caused by accidental contact with the main body 1 or the lid 2 of the container. If it is made too deep, it will become hard and difficult to open and close.

Furthermore, when attempting to integrally mold the main body 1, lid body 2, and hinge part 3 with a mold, a side core is not used because the engaging part 1b and the locking part 2b are perpendicular to the direction of mold removal. The problem was that it was necessary and difficult to make.

In view of the conventional problems, the present invention integrates the main body and the lid with a hinge part, and also forms the locking part and the engaging part integrally, so that they can be reliably locked and can be opened and closed easily. The object of this invention is to provide an openable container that can be easily manufactured using a mold.

Means for Solving the Problems The openable and closable container of the present invention comprises a main body and a lid made of the same material, each of which has opposing surfaces open and can be freely opened and closed using one part as a hinge, and a lid of the main body. A closing band part made of the same material as described above and integrally extending from the main body on the other side opposite to the one side part provided with the hinge part and having a locking part at the tip, and a lid facing the closing band part. an engaging part provided near the edge of the upper surface of the body so that the locking part is locked, and the closing band part is provided with a first bending hinge part at a connecting part with the side part of the main body. In addition, a second hinge portion is provided at a portion facing the upper edge of the side portion of the lid body, and the above-mentioned locking portion is provided at the tip of the second bending hinge portion so that the lid body can be engaged while being bent toward the top surface side. It is configured to be locked in the joint.

Effects According to the present invention, the main body and the lid can be freely opened and closed around the hinge part, and the closing band part integrally provided on the open side of the main body is connected to the first. While being bent by the second bending hinge part, when the lid is closed, the locking part can be bent to the top surface of the side edge of the lid body, and the locking part can be locked to the engaging part. When opening the lid, the lid can be opened by pinching up the tip of the closing band.

EXAMPLES Hereinafter, examples of the present invention will be explained in detail based on FIGS. 1 to 4, which show examples.

In the figure, 10 is the main body of the cabinet constituting the container, 11 is the lid, and both 10 and 11 are integrally connected with one part as a hinge part 12, and are configured to be openable and closable around the hinge part 12. ing. Approximately in the center of the lower edge of the side wall 10a facing the hinge portion 12 side of the main body 10, a closure band portion 13 is formed integrally with the main body 10 from the same material. A stop portion 14 is provided. Furthermore, the closure band portion 13 is provided with a first bending hinge portion 13a formed thinly at the connection portion with the main body 10.
Further, the second bending hinge portion 13b is formed in the portion where the locking portion 14 is left. On the other hand, the lid 11. On the upper surface near the upper edge of the side wall 11a facing the hinge portion 12 (III), there is a locking portion 1 provided on the closing band portion 13.
4 forms an engaging portion 15 to be locked. Furthermore, when the closing band portion 13 is bent in the direction of the arrow around the first bending hinge portion 13a, the side walls 10a and lla have a
Grooves 10b and 11b are formed to accommodate the closure band 13. Here, when the closure band part 13 is bent in the direction of the arrow around the first bending hinge part 13a, the second
The bending hinge portion 13b is formed so as to face the upper edge portion 11c of the side wall 11a of the lid body 11. Further, the locking portion 14 is formed with a bulging portion 14a and a hollow portion 14b. On the other hand, the engaging portion 15 has a hole diameter smaller than the diameter of the bulging portion 14a of the locking portion 14, and when inserting and locking the locking portion 14 into the locking portion 15, The portion 14 is elastically deformed and inserted. Further, a recess 16 is formed in the vicinity of the engaging portion 15, which can be used as a finger insertion portion when hooking a finger on the tip edge 13c of the closing band portion 13 in the locked state and pinching it up to open it. There is.

The hinge portion 12, as shown in FIGS. 3 and 4,
Rear side wall 10d of main body 10 and rear side wall lid of lid body 11
between the connecting piece 12a and the first thin hinge 12b.
and a second hinge thin wall 12c, and the connecting piece 12a forms a part of the rear side wall in the closed state together with the side wall 10d and the lid. Note that 12d indicates a through hole, which is formed between the side wall 10d, the lid and the connecting piece 12a, and between the hinge thin walls 12b, 12b and 12C212c.

The containers constructed as described above are all made of the same synthetic resin material and are integrally molded using a mold, and the molding is performed in the open state shown in FIG. 3. Therefore, the cost of the mold itself can be significantly reduced, and the manufacturing process can also be greatly simplified.

Effects of the Invention As explained above, the present invention is a container consisting of a main body and a lid body which are integrally constructed so as to be openable and closable around a hinge part, and which extend integrally from the main body and have a locking part at the tip. It includes a band portion and an engaging portion formed near the upper edge of the lid body opposite to the locking portion, and the locking portion is engaged while bending the bending hinge portion provided on the closing band portion. It is configured so that it can be locked in the joint, and when closing the lid on the main body, it can be locked easily and reliably by a simple operation of bending and locking the closing band. . Furthermore, the lid can be opened easily by pinching up the tip of the closing band and opening the lid. Furthermore, since the closure band can be formed integrally with the main body and lid while being bendable via the bending hinge, molding it is easy and the cost of the mold itself can be reduced. In addition to being able to significantly reduce
The manufacturing process can also be greatly simplified, which has great effects.
