Description

[Detailed Description of the Invention] This invention relates to a container with a lid, and aims to provide a container in which the container body and the lid can be easily and securely fitted together, and the container body and the lid can be used in common.

In conventional containers with lids, the fitting structure between the container body and the lid is such that a convex portion provided on one peripheral wall portion and a concave portion provided on the other peripheral wall portion are fitted into each other. There were many.

However, in the conventional fitting structure as described above, since the shape and structure of the fitting part between the container body and the lid are different, it is impossible to form both in the same shape and use the lid and the container body in common. This is not only inconvenient in manufacturing, but also an obstacle in reducing manufacturing costs.

Therefore, in this invention, the above-mentioned inconvenience can be solved, and it is also possible to provide something suitable for use.As for its structure, the container main body and the lid body are formed from halves of the same shape, and each A peripheral wall formed in a tapered shape that becomes smaller from the upper edge to the lower part of the half body is provided with a flange portion projecting outward from the peripheral wall that is thicker than the peripheral wall and extends around the entire upper edge of the peripheral wall that is inclined in the front-rear direction. The upper surface of the part is divided into a plurality of fitting parts, and each fitting part is divided into two into an inner and outer circumference, a convex part with an oblique end surface is formed on one side, a recessed part is formed on the other side, and the adjacent part is divided into two parts. In the fitting portions, the concave and convex portions are arranged so that the inner and outer circumferences are reversed, and the oblique end faces of the convex portions are formed to intersect with each other, and the planar shape of the flange portion is The fitting portions are formed symmetrically in the front, rear, left and right directions, and the corresponding fitting portions in the front, back, left and right directions are arranged such that their concave and convex portions are reversed on the inner and outer peripheries.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

In Figures 1 to 5, A is the half body that becomes the container body, and A' is the half body that is the lid. Both A and A' are formed in exactly the same shape and have a rectangular planar shape. , made of foamed polystyrene, etc.

In each half A, A', the upper edge of the peripheral wall 1 is sloped so that the height gradually differs in the front-rear direction.For example, in the case of FIGS. 1 and 2, in the container body A, the peripheral wall 1 is lower on the front side 1l has a high peripheral wall 1h on the back side, and conversely, the lid A' has a high peripheral wall 1h on the front side and a low peripheral wall 1l on the back side. Further, the entire peripheral wall 1 is formed in a tapered shape that becomes smaller from the upper edge to the lower part, and the halves A, A
They can be sequentially fitted and stacked (Fig. 5). At the upper edge of the peripheral wall 1 having an inclination in the front-rear direction, the peripheral wall 1
A flange portion 2 protruding outward from the peripheral wall 1 is provided around the entire circumference so as to be thicker than other portions.

Then, the upper surface of this flange portion 2 is connected to the container body A.
The upper surface of the flange portion 2 is connected to a plurality of fitting portions 3, 3...
Each fitting part 3 is divided into two parts, an inner circumference and an inner circumference, and one of the inner circumference side and the outer circumference side is formed as a convex part a, and the other side is formed as a concave part b, and the adjacent fitting parts 3, 3 are formed so that the arrangement of the concave and convex portions a and b is opposite to each other on the inner and outer peripheries, and the concave portion a and the convex portion b of each fitting portion 3 corresponding to each other on the container body A and the lid A' are and are covered with each other (Fig. 1).

Then, in the fitting parts 3, 3..., the shape of both end surfaces e, e of each convex part a is formed in an oblique shape, and the oblique end faces e of the convex parts a of adjacent fitting parts 3 bite into each other. It is shaped to intersect with difference. (8th
(See Figure 9, etc.)

Furthermore, the planar shape of the upper surface of the flange portion 2 and the division pattern of the fitting portions 3, 3, etc. are symmetrical in the front, rear, left, and right directions, and the uneven portions b, a of the fitting portions 3, 3 corresponding to each other in the front, rear, left, and right directions are symmetrical. The inner and outer circumferences are arranged to be opposite to each other.

That is, in the plan view of the halves A and A' (Fig. 3), when the rear half is folded back to the front half with the front and rear center line (X-X') as the boundary, the flange part 2 The external shapes and the division patterns of the fitting parts 3, 3... exactly overlap, and the corresponding uneven parts b and a of each fitting part 3, 3... are arranged in completely opposite directions on the front side and the back side. . Also, when the left half is folded back into the right half with the left and right center line (Y-Y') as the boundary, the outer shape of the flange portion 2 and the fitting portions 3, 3, . . . division pattern exactly overlap, as described above. Furthermore, the corresponding concave and convex portions b and a of each of the fitting portions 3, 3, . . . are arranged in completely opposite directions on the right and left sides.

To explain specifically in the illustrated embodiment,
A square flange portion 2 that is symmetrical in the front, rear, left, and right directions is divided into four fitting portions 3, 3... using the center part of the four sides as a dividing line, and one diagonal line of each fitting portion 3, 3... In the two upper fitting parts 3, 3, a convex part a is formed on the inner periphery side and a recess part b is formed on the outer periphery side. Two fitting parts 3, 3 located in
In contrast to the above, the concave portion b is formed on the inner circumferential side and the convex portion a is formed on the outer circumferential side, thereby satisfying each of the above-mentioned conditions. Note that the convex portion a in the figure is indicated by diagonal lines for convenience.

Therefore, as long as the above conditions are met, the planar shape of the upper surface of the flange portion 2 and the division pattern of the fitting portions 3, 3, etc. can be freely changed, and the planar shape of the flange portion 2 may be rectangular, diamond, or rectangular, in addition to the above-mentioned square. Hexagonal, circular (Figures 6 and 7), elliptical, etc.
It suffices if the shape is symmetrical in the front, back, left and right, and the fitting part 3,
In addition to the division pattern 3, which is equally divided into the four parts described above, it may also be divided into eight parts (Fig. 7) or more, and the sizes of the fitting parts 3, 3, etc. are not exactly the same, but may be long or short. Even if there are a mixture of fitting parts 3 having different sizes, it is possible to implement the fitting part 3 as long as the corresponding fitting parts 3 in the front, rear, left and right sides have the same shape (not shown).

In addition, the overall shape of the half bodies A, A' can be formed into any shape regardless of the planar shape of the flange portion 2, and the materials of the half bodies A, A' include polystyrene, polyethylene, polypropylene, etc. It is preferable to use foamed materials of various synthetic resins in terms of heat insulation and cushioning properties, and it is also possible to use non-foamed materials of the various synthetic resins mentioned above.

Prepare two halves A and A' having the above structure,
One is used in combination as the container body A and the other as the lid A', but at this time, the lower peripheral wall 1l of the container body A and the higher peripheral wall 1h of the lid A' face each other,
If the lids are fitted so that the high peripheral wall 1h side of the container body A and the low peripheral wall 1l side of the lid A' face each other,
The heights due to the inclination of the peripheral walls 1 of both A and A' are canceled out, and the upper and lower surfaces of the container as a whole become parallel, which is convenient for stacking the containers, etc. (see FIGS. 1 and 6). Also, unlike the above, if the lid A' is reversed and the high peripheral walls 1h and low peripheral walls 1l of the container body A and lid A' are facing each other and the lids are fitted together, the entire container will have an even more inclined top surface. This is convenient, for example, when tall and short items such as cakes of different sizes are mixed together as stored items (see FIG. 4).

According to the lidded container of this invention constructed as described above, the container main body and the lid are shared by halves of exactly the same shape, making it easy to manufacture and significantly reducing manufacturing costs. become.
Furthermore, the fitting structure provides a very tight fitting state.

That is, as a fitting structure, the upper surface of the flange part on the upper edge of the peripheral wall is divided into a plurality of fitting parts, and each fitting part is divided into two parts on the inner and outer peripheries to form an uneven part, and the uneven part connects with the container body. The lid can be tightly covered, and in particular, the planar shape of the flange part and the division pattern of the fitting part are made symmetrical in the front, back, left and right sides of the half body, and the fitting parts that correspond to each other in the front, back, left and right sides have their uneven parts. Since the inner and outer circumferences are arranged oppositely, even if the lid is reversed from front to back with respect to the container body, the fitting condition remains exactly the same and the lid can be tightly covered. Due to the inclination, the container as a whole can be used in two different shapes or modes of use: a container with parallel top and bottom surfaces and a container with a sloped top surface, making it even more convenient in terms of appearance and usage. This will increase its usefulness.

Furthermore, due to the inclination of the upper edge of the peripheral wall in the front-rear direction,
When displaying and selling stored items in a container body, by lowering the peripheral wall on the front side, the stored items are easy to see, the display effect on the appearance is good, and the stored items can be easily taken out. In addition, since the flange part is formed thicker than the peripheral wall, the width of the mating part can be made sufficiently thick even when the peripheral wall is thin, and a reliable mating state can be achieved. It also has the effect of saving materials by making it thinner.

Furthermore, since the peripheral wall is formed in a tapered shape that becomes smaller from the upper edge to the lower part, when transporting or storing the halves, it is possible to stack many halves and store them compactly. Rather than preparing a set of container bodies and lids with different sizes, any halves can be combined and used as a container body and lid, making removal even more convenient. Furthermore, since the end face of the convex part is formed in an oblique shape, the end face corner part of the convex part can be prevented from being damaged or chipped during use, especially during the operation of covering, and the cover can be fitted smoothly.
Moreover, even if there is a gap between the end faces of the convex parts of the lid and the container body that face each other when the lid is closed due to dimensional errors in the convex parts that occur during manufacturing, the end faces of the other convex parts that intersect with each other This prevents the gap from being closed and the formation of a large gap leading to the inside and outside of the container (Figure 9), making it suitable for storing items and giving it a good appearance. In the case of ice cream containers, etc., it is more suitable in terms of heat insulation inside and outside the container, has excellent heat insulation and cold insulation effects, is easy to handle, and has low manufacturing costs.
