Description

[Detailed description of the invention] The present invention is designed to be attached to a container, and the lid is elastically engaged with an engagement groove provided at the opening edge of the main body, thereby sealing the inside of the main body and making it easy to fit and remove the lid. This is what I did.

Therefore, the present invention consists of a rectangular main body and a lid, at least one of which is flexible, the main body is provided with a flange at the opening edge, and an engaging groove is formed on the flange by an inwardly directed jaw protruding from the flange. The jaw is formed with a relief part in the radial direction at the corner of the opening edge, and the lid has a flange facing the flange of the main body on the outer periphery and a convex part corresponding to the relief part of the jaw of the main body. The container has a structure in which the dimension between the flange end and the convex end substantially matches the dimension between the engagement grooves of the main body with which they are engaged.

Examples of the present invention will be described in detail below with reference to the drawings. Here, we will explain a case in which the main body and the lid are separate and independent, but a type of container that can be opened and closed by connecting the two on one side may also be used. 1 is a rectangular main body, and 2 is a rectangular lid, both of which are made of synthetic resin and have flexibility. The main body 1 has a tsuba 11 on the edge of the opening 0.
a, 11b, 11c and 11d, and inward jaws 12a, 12b, 12c and 12d protruding from the outer periphery of these collars 11a to 11d.
Engagement grooves 13a, 13b, 13c and 13
d, and these jaws have diagonally outward relief parts 15a, 15b, 15c and 15 at corner parts 14a, 14b, 14c and 14d of the edge of opening 0.
d is formed. The planar shape of these relief parts may be any suitable shape, but in the drawing they are arcuate.
In addition, the engaging grooves 13a to 13d are shallow and the jaws 12a to 1
Grooves 13a to 13d at relief parts 15a to 15d of 2d.
If these grooves 13a to 1 disappear,
3d also has grooves 16a corresponding to the relief parts 15a to 15d.
It is preferable to form ~16d. The lid 2 has a flange 21a on the outer periphery that faces the flange 11a to 11d of the main body 1,
21b, 21c and 21d. Although these flanges 21a to 21d cannot be clearly recognized when the lid 2 is flat, they correspond to portions facing the flanges 11a to 11d, respectively. Corner part 2 of this lid 2
4a, 24b, 24c and 24d are formed with convex portions 25a, 25b, 25c and 25d corresponding to the relief portions 15a to 15d of the jaws 12a to 12d of the main body 1. Although the planar shape of these convex portions may be arbitrary, in the drawing, they are arcuate. Therefore, the dimension W between the ends of the flange 21a and 21c of the lid 2, and the dimension W between the flange 21b and 21d.
End-to-end dimension l and convex portions 25a and 25c, 25b and 2
5d, the end-to-end dimension d is the end-to-end dimension of the engaging grooves 13a and 13c of the main body 1, which are respectively engaged, and the grooves 13b and 13.
d Dimension between ends and grooves 16 at relief parts 15a to 15d
a and 16c, and 16b and 16d, so that when the lid 2 is placed on the main body 1, the outer edges of the flanges 21a to 21d of the lid 2 are close to the jaws 12, respectively.
It is pressed by a to 12d to tightly close the opening 0.

In the drawings, reference numeral 18 designates a recess provided in the center of the jaw 12a on one side, and reference numeral 28 designates a knob provided on the flange 21a of the lid 2 at a position that fits the recess 18.

In the illustrated container, an item to be stored is placed in the main body 1, and the lid 2 is tilted so that the tab 28 is located upward.
5c, convex portions 25b and 2 at both ends of the collar 21c of the lid 2.
5c and this collar 21c to the groove 13c of the jaw 12c, so that the knob part 28 is in the concave part 1.
8. Press down the lid 2 in the direction that it fits into the lid 8. Convex portion 25b
and 25c gradually fit into the grooves 16b and 16c of the escape parts 15b and 15c while rotating together with the lid 2, and the collar 21c also fits into the groove 13c. The flanges 21b and 21d at both ends of the lid 2 are connected to the jaws 12b and 1, respectively.
2d springs outward or deforms itself inward, or both deform and finally fit into the grooves 13b and 13d. Similarly, the convex portions 25a and 25d
are fitted into the grooves 16a and 16d of the escape parts 15a and 15d, respectively, and the collar 21a is fitted into the groove 13a. Finally, the tab 28 is fitted into the recess 18, and the lid 2 is tightly fitted onto the main body 1.

When removing the lid 2, if there is a knob 28, pinch it and pry it open, and if there is not, pressurize the lid 2 or the main body 1 to deform it. In either case, lid 2
The collars 21a to 21d and the grooves 13a to 13d of the main body 1
Engagement and convex portions 25a to 25d and relief portions 15a to
Since the grooves 16a to 16d of 15d are disengaged,
Both will be free.

According to the present invention, the flange on the outer periphery of the lid engages with the engagement groove provided on the opening edge of the main body to seal the inside, making opening and closing operations easy. Since a relief part is provided on the side and a convex part that fits the relief part is provided on the lid side, the mating operation can be done smoothly by rotating the lid.Moreover, in the mated state, this convex part fits into the relief part. It has various effects, such as being able to properly seal the inside.
