JPS5822934Y2 - Synthetic resin container with lid - Google Patents

Description

[Detailed description of the invention] The present invention is a container with a lid made of synthetic resin used for transportation of agricultural products, etc., in which the lid is attached to a rectangular basket-like container. This invention relates to improvements to facilitate and ensure adhesion.

As described in Japanese Utility Model Publication No. 53-53633, etc., this type of container with a lid has an outwardly bent edge around the upper end surface of the container, and a downwardly bent edge around the side edge of the lid. At the same time, a protruding piece of a constant width is provided at the lower end of the downwardly bent edge to form an inward sideways protruding piece, and the protruding piece is engaged with the lower end of the outwardly bent edge while the lid is attached to the container. It is configured to maintain the adhered state.

However, as mentioned above, since the protruding piece protrudes inward to a certain width, its entire tip comes into contact with the outwardly bent edge when the lid is attached to the container.
There is a drawback that the lid cannot be attached unless pushed in with strong force.
For this reason, workability was extremely poor when handling a large number of containers.

Therefore, the present invention has been improved so that the width of the protruding piece is gradually narrowed in one direction so that the lid can be attached easily and reliably with extremely light force.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a square cage-like container formed by integral molding of synthetic resin, and has four circumferential side walls 2... outwardly bent edges 3 at the upper ends thereof, and A hanging edge 4 is provided hanging at the tip of the curved edge 3.

5 is a lid that is attached to the container 1 in a lid-like manner,
A concave portion 6 that fits into the outwardly bent edge 3 is provided around the four circumferential side ends, and furthermore, the tip of the concave portion 6 is connected to the hanging forest, 4 at the outer end of the concave portion 6.
A downwardly bent edge 7 is provided around the periphery so as to substantially coincide with the tip of the holder.

8... are a pair of protruding pieces provided at the tips of the downward bent edges 7a, 7a which are opposed to each other among the downward bent edges 7, and project inwardly and laterally, and each The width of each of the protruding □ pieces 8 is gradually narrowed toward the inside of the lid 5, and is formed in a shape.

Note that 9...;... are arch-shaped legs that are protruding inside the concave portion 6 at each corner of the lower surface of the lid 5, and serve as spacers when stacking the lids. let

10... is a tag attachment hole bored in the concave portion '6.

Further, reference numeral 11... is a reinforcing rib that is bent inwardly on the four circumferential side walls 2... to reinforce the container 1, and a concave portion 6 provided on the lid body 5. The rib 11...
Widened portions 12 are provided in accordance with the concave curves of....

Next, to explain the operation, the lid 5 is placed on the container 1 containing fruits and vegetables, etc., and the concave portions 6 provided at the four circumferential ends are pressed to engage the outwardly bent edges 3, and at the same time each protrusion The piece 8 is engaged with the lower end of the depending edge 4.

In this case, each protruding piece 8 is formed so that its width is gradually narrowed toward the inside of the lid body 5, as shown in an enlarged view in FIG. The sides can be slid to engage the lower end of the depending edge 4.

Once engaged, the engaged state can be maintained reliably around the wide portion.

As described above, the container with a lid of the present invention has a projecting piece provided laterally inward at the tip of the downwardly bent edge provided at the circumferential end of the lid body, and the width of the protruding piece is gradually narrowed toward one side. By pressing the lid with extremely light force, it is possible to easily and reliably attach the lid to the lid.

Therefore, the work of attaching the lid becomes easy, and the workability is significantly improved, especially when handling a large number of containers, and the intended purpose can be fully achieved.
