Description

[Detailed Description of the Invention] This invention relates to a container, particularly a container whose lid can be easily attached and detached.

BACKGROUND ART Containers in which a container body and a lid are connected to each other by a single edge are conventionally known.

To prevent the lid from opening easily in these types of containers, there are methods that use rubber bands, adhesive tape, etc., and methods that engage the lid with the container body. There is the inconvenience of having to prepare bands, adhesive tape, etc. separately.

Therefore, there is a need for containers that are easy to engage, easy to open for transportation and other purposes, and easy to open for product removal.

For this reason, there are containers that have a dovetail-shaped protrusion on the flange of the lid and a dovetail-shaped engagement recess on the flange of the container body so that the two can be freely engaged and detached (for example, Showa 52-43
570), according to such a structure, since the protruding piece is engaged with the recess while being bent downward against its elasticity, bending stress is concentrated on the protruding piece, and on the contrary, it is applied to both sides of the protruding piece. The flange of the lid is curved upwards, making it difficult for the flange of the lid to come into close contact with the flange of the container.

Since the engagement area between the protrusion and the recess is narrow, it also has the disadvantage that it easily comes off.

The object of this invention is to provide a container that eliminates the above-mentioned drawbacks.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The container of this invention is molded from synthetic resin such as expanded polystyrene, and has one side edge of a lid 2 integrally connected to one side edge of a container body 1 at a connecting portion 3.

Although the illustrated lid 2 has approximately the same depth as the container body 1, the size, shape, depth, etc. of the container body 1 and the lid 2 are appropriately selected depending on the contents to be stored.

Flanges 15 are provided on the opening edges of the main body 1 and the lid 2, respectively.
15' are provided, and in particular, the part of the collar 15, 15' facing the connecting part 3 is formed wider than the other part, and the engaging part 4, 4' is formed in this part.

The engaging part 4 of the main body 1 has two notch gaps 9, 9 in the collar 15.
', and is divided into a central flange 10 and both side flange parts 5.51, and a rising step part 13.degree. Locking pieces 6, 6' are provided therebetween.

The central flange 10 is formed into a trapezoid whose inner edge is longer than its outer edge by providing the cut gaps 9, 9' obliquely in the same plane in the direction of both corners.

Furthermore, the locking pieces 6, 6' are formed into a trapezoid whose outer edge is longer than the inner edge, and by providing a notch 16.16' on the inner edge, the locking pieces 6, 6' have a stepped portion 13°13. ′ part is flexible.

Note that the rising height of the step portions 13, 13' is approximately equal to the thickness of the collar 15.

Next, the engaging part 4' of the lid 2 consists of the same central flange part 7 and both side flange parts 12, 12', but in this case the locking piece 8
, 8' are provided on both sides of the central flange 1 via recessed step portions 14.14', and are bendable by providing notches 17.17' on the inside thereof, and the locking pieces 8, 8
Cut gaps 11, 11' are provided between the flange 7 and the flange portions 7 on both sides.

To engage the engaging parts 4, 4' constructed as described above, first insert one of the locking pieces 8 of the lid 2 into the lower surface of the locking piece 6 through the gap 9 of one side of the main body 1 (see Fig. 2). reference).

In this case, the locking pieces 6 and 8 are inserted into each other after the lid 2 and the main body 1 are slightly shifted in opposite directions, but the lid 2 and the main body 1 are easily shifted due to slight deformation of the connecting part 3. .

In this manner, with the locking pieces 6 and 8 inserted into each other, the other locking pieces 6' and 8' are not in the inserted state as shown in FIG. By pushing in the locking piece 8' in the direction of the arrow, the locking piece 6' on the main body is bent as shown by the chain line, and conversely, the locking piece 6' on the main body is placed on the upper side, and the locking piece 8' on the lid is placed on the lower side. When the two locking pieces 6/, 8/ are turned to the side, as shown in FIG. 3, the locking pieces 6/, 8/ are also inserted in the same way as in the case described above, and the main body 1 and the lid 2 are engaged with each other.

In the engaged state, the engagement will not come off even if either the lid 2 or the main body 1 applies force to the other in the horizontal or vertical direction.

However, when the lid 2 is strongly pulled upward, the locking pieces 8, 8 of the lid 2
' is bent downward and the locking piece 6.6' of the main body 1 is bent upward, so that the engagement is released and the contents can be taken out.

Although FIG. 3 shows that there is a gap 16 between the collars 15 and 15', this gap 16 has been eliminated and 41
5 and 15' may be formed so that they fit exactly together.

As can be seen from the above description, the parts directly involved in the engagement between the main body 1 and the lid 2 are the flanges 5 and 5' on both sides of the main body 1.
and its locking pieces 6, 6', and in the case of the lid 2, the central flange 7 and its locking pieces 8, 8'; There is no direct relationship.

Therefore, in the main body 1, the center flange 10 is omitted, and the distance t between the locking pieces 6, 6' is set to be such that the center flange 7 of the lid 2 can be received.
, 12' may be omitted.

However, the central flange 10 of the main body 1 and the side flange 12 of the lid 2,
12' has the effect of reinforcing the entire flange by overlapping with the opposing flange 7°5.5'.

In addition, the step portions 13, 13 of each locking piece 6, 6', 8, 8'
'.

The provision of 14.14'v makes it easy to insert, and in the engaged state, the entire flange becomes flat as shown in FIG. 3, making it difficult to come off, and also has the advantage of being favorable in terms of appearance.

Furthermore, the central flange portions 10, 7 and the locking pieces 6°6',
The shapes of 8 and 8' do not necessarily have to be trapezoidal as shown in the figure, but the cut gaps 9, 9', 11, and 11' are formed at right angles to the side edges of the main body 1 and the lid 2, and the central flange parts 10, 7
The locking pieces 6, 6', 8, 8' may be formed in a rectangular shape, but it is better to form the locking pieces 6, 6', 8, 8' in a trapezoidal shape as shown in the figure.
8, 8' becomes easy to base.

As described above, the container of this invention has the locking pieces 6 and 6' provided on both side flanges 5 and 5' of the container body 1, and the locking pieces 8 and 8 provided on the center flanges 7 of the lid 2, respectively. 8' are inserted one above the other, and the lid 2 is engaged with the container body 1, so it can be easily engaged and will not come off due to external forces applied during transportation etc. .

Further, when the lid 2 is pulled upward, it is disengaged, so that it can be opened easily.

Furthermore, since the locking parts 6, 6' and 8, 8' are provided through the stepped parts 13, 13' and 14, 14', respectively, they can be easily inserted, and in the engaged state, the flange of the lid 2 can be easily inserted. Part 12
, 12' and the flange 5° 5' of the container body 1 can be easily aligned flatly, and the engagement area can be sufficiently large, so that it is difficult for them to come off.
