Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a synthetic resin lid and a synthetic resin container using the same.

[0002]

2. Description of the Related Art In the case of a conventional synthetic resin lid or container, in order to improve the appearance of the stored product, in the case of a square or substantially square shape, at least one set of peripheral side heights is required. It has been devised so that the product can be viewed as three-dimensionally as possible by giving a difference in height.

However, if a difference in height is given to the height of the peripheral side portion, taking a lid 50 shaped as shown in FIG. 6 as an example, when a large number of these lids 50 are stacked, the peripheral side portions 51, 52 are formed. Because of the height of the stack, the stacking state is unlikely to be vertical, and the stacking state is inevitably inclined to the lower side as shown in FIG. 7, and the peripheral parts 53 and 54 are formed with protrusions 55 and 56 for preventing overlap. Even projecting part 5
When the members 5 and 56 are in the same position, they actually fit each other, and the inclined state is still not improved, and the collapse state in the stack state is apt to occur, so that it is difficult to supply to the automatic packaging apparatus and it is difficult to handle. .

[0004] The same applies to the case where the above-mentioned lid-shaped one is used as a container. However, another example of a container 60 is shown in FIG.
In the case of a shape in which the height of the pair of opposed surfaces is formed with a height and the opening angle with respect to the height of the bottom surface 63 is larger than a right angle, both of the height due to the height difference are provided. Although the angles α ₁ and α ₂ of the peripheral side of were made equal to make it easy to remove the mold during molding,
In this case, since the opening angles β and γ with respect to the bottom surface are different,
In the case of stacking, the stacking state is easily inclined toward the peripheral side on the side where the opening angle is large and the height difference is low, as shown in FIG. 9. Had been requested.

[0005]

Therefore, in order to solve these problems, the present invention has been made to surely realize a vertically stable stack state.

[0006]

According to the present invention, there is provided a lid made of a synthetic resin which solves the above-mentioned problems.
As described in the above, the peripheral side part raised from the peripheral part that can be put on the peripheral part of the container having a square or substantially rectangular shape and the top plate part following this are formed, and a pair of the peripheral parts facing each other is formed. A synthetic resin lid that is formed to be inclined with respect to the top plate with a height difference, and at least one set of opposing peripheral sides of a plurality of opposing peripheral sides. The protrusions for stacking are formed from the outside to the peripheral edge of the lid, and the positions of the protrusions are set in the lids that are stacked so that the upper surface of the protrusion contacts the inner peripheral surface of the other lid that is stacked. It is characterized in that the distance between the lids to be stacked is changed by a protrusion so that the lids are sequentially stacked in a vertical state.

According to the first aspect of the present invention, even when a large number of sheets are stacked, the protruding portions for stacking surely keep the gap between the lids and prevent the lids from being inclined and stacked. The stacking is performed vertically, so that the stack collapse phenomenon can be eliminated and the supply to the automatic packaging device and the like can be stabilized. Further, according to the present invention, as described in claim 2, the lid is formed in a rectangular shape, the height difference of the peripheral side portion is attached to a pair of long sides, and the protruding portion for stacking is formed on the long side. It is characterized in that it is formed as a lower peripheral side of the side and a pair of peripheral sides on the shorter side, so that a difference in height is always given to the peripheral side, and And the point that the whole lid easily tilts during stacking can be reliably prevented by the protruding portion for the stack formed on the lower peripheral side on the long side, which is convenient for maintaining the stacking state in the vertical state It is.

Next, if a small protrusion is further formed below the stack protrusion, the small protrusion contacts the inner surface of the peripheral side surface of the lower lid on which the small protrusion is stacked. It can work more effectively by preventing inclination when stacking. Further, according to the present invention, as described in claim 4, a container combined using the lid according to claim 1 or claim 2, wherein
A pair of opposing heights is formed with a height difference, and the opening angle with respect to the bottom surface of the peripheral side portion with the height difference is wider than a right angle and formed at the same opening angle. In this case, it is possible to maintain a very vertical stable stack state even in such a container.

It is also possible to use the above-mentioned lid as a container and the container as a lid inverted.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of the lid A according to the present invention, and FIG. 2 shows a stacked state.
The lid A has a rectangular or substantially rectangular shape, and in the case of the figure, the lid A has a substantially rectangular shape, in which three sides are linear and one side forms a large arc, more specifically, a substantially rectangular lid shape. ,
Peripheral parts 10, 11, 12, which can be placed on peripheral part b of container B
13, the peripheral side parts 14, 15, 16, 17 are formed, and a top plate part 18 following them is formed.

[0011] Of the above-mentioned peripheral side portions, a height difference H, h is added to the height of a pair of peripheral side portions 16, 17 facing each other so as to be inclined with respect to the top plate portion 18. Then, of the peripheral side portions, at least the protruding portion 1 for the stack extends from the outside of the pair of peripheral side portions 16 and 17 facing each other to the peripheral edge portions 12 and 13.
9a and 19b are formed respectively, and in the case of the drawing, the protruding portion 19 for stacking is also formed on the lower peripheral side portion 11 among the long sides of the rectangle.
c is formed. Further, the projections 19a, 19b,
The positions of the protruding portions 19a, 19b, and 19c are changed between the lids A, A that are stacked so that the upper surface of 19c abuts the inner surface of the peripheral edge of the other lid A that is stacked. The position change prevents the projections from fitting together, and the gaps between the stacked lids are held by the projections 19a, 19b, 19c, and the lids A, A,...
Are sequentially stacked in a vertical state (FIG. 2).
reference).

In particular, a small projection 30 is provided below the projection 19c.
This small projection 30 abuts on the inner surface of the peripheral side portion of the lower lid, and acts more effectively to prevent inclination during stacking. Next, FIG. 3 shows a container (container main body) B used in combination with the lid A, and FIG. 4 shows a stacked state of the container B.

The container B is formed such that the height of a pair of opposed peripheral side portions 22, 23 among the peripheral side portions 20, 21, 22, 23 raised from the bottom surface 25 is different in height. . The opening angles β and γ of the peripheral side portions 22 and 23 with the height difference with respect to the bottom surface 25 are larger than a right angle and are formed at the same opening angle. It is possible to prevent the stack state from tilting to a certain lower side, easily maintain a stable vertical stack state, and prevent the collapse of the load in the stack state (see FIG. 4).

The above-described lid A is used as a container (main body), and the above-described container B is used as a lid, so that the stable stacking effect, which is a feature of the combination, is completely changed by the reverse usage. Making either or both a transparent synthetic resin or a foamed resin is a technical content that can be freely selected in any of the embodiments.
