Description

[Detailed explanation of the invention] This invention is a gas mat (aluminum foil saucer for gas stoves)
Regarding packaging containers, the lid can be easily fitted onto the container body, and
The purpose is to make it difficult for the lid to come off and at the same time to make it easy to open the lid.

Among conventional gas mat packaging containers, gas mat packaging containers with a central opening have a structure in which a lid fits into the central opening and outer periphery of the container body. It takes time to fit the parts in order.

Moreover, if the fit is strong, it will be difficult to open the lid, making it inconvenient to take out the gas mat.

On the other hand, if you want to make it easier to open the lid, you have to make the fit looser, which creates a contradiction in that the lid is more likely to come off.

In the end, the conventional product still had the disadvantage that it was difficult to open the lid or that the lid was easy to come off.

In order to solve the above-mentioned drawbacks, the present invention has been designed to fit the lid to the container body in a manner that prevents it from coming off at the inner peripheral edge of the central opening of the container body, and to have a shape-retaining peripheral wall that expands toward the outside for guiding the outer peripheral edge of the lid. is fitted onto the outer circumferential wall of the container body to provide a gap for opening the cover between at least the lower edge portion of the shape-retaining circumferential wall and the outer circumferential wall, making it easy to fit the lid and also make it easy to open the lid. .

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

As shown in FIG. 1, the gas mat packaging container P has a substantially square shape in plan view, and circular openings 3a and 3b are provided at the center of the container body 1 and lid 2, which are each formed separately. It is being

As shown in the vertical cross-sectional front view of the gas mat packaging container P in FIG. Joint part 4
is inserted from above into the fitted portion 5 formed on the inner circumferential edge of the opening 3b of the container body 1 and is internally locked.

When this insertion is removed, the inner circumferential surface of the tapered guide portion 4a extending from the lower edge of the locking fitting portion 4 comes into contact with the arcuate slope of the fitting portion 5, and the locking fitting is completed. The mating portion 4 is guided and deformed toward the inner periphery while fitting into the mating portion 5 .

After the fitting, the locking fitting part 4 is locked at the tip of the fitted part 5 to prevent it from coming out.

On the other hand, from the outer peripheral edge of the lid 2, there is a shape-retaining peripheral wall 6 that expands toward the end.
is extended downward, and this is the outer peripheral wall 7 of the container body 1.
is fitted externally.

Here, the upper edge of the shape-retaining peripheral wall 6 is fitted into the outer edge 7a of the outer peripheral wall 7 in abutting manner, but at least the lower edge 6a of the shape-retaining peripheral wall 6
A gap for opening the lid is provided between the outer circumferential wall 7 and the outer peripheral wall 7, so that it is easy to place a finger on the lid when opening the lid.

When the container body 1 is covered, the inner circumferential surface of the shape-retaining circumferential wall 6 that flares out comes into contact with and is guided by the outer edge 7a of the outer circumferential wall 7, so that the container body 1 can be closed smoothly and effortlessly.

When taking out the gas pine hM from the packaging container P, hold the packaging container P with one hand through the opening portions 3a and 3b, and insert the finger of the other hand into the gap for opening the lid to remove the shape-retaining peripheral wall 6. When the shape-retaining peripheral wall 6 is easily removed from the outer peripheral wall 7 and a large moment is applied to the locking fitting part 4, the locking fitting part 4 is pulled up diagonally upward on the outer peripheral side. It will be removed from the

The packaging containers P are formed in a cross-sectional shape that allows them to be stacked in multiple stages, as shown by imaginary lines.

The container body 1 and the lid 2 are made of a yellow transparent synthetic resin material (vinyl chloride, etc.).

In this case, the metallic of the gas mat M inside and the yellow of the container give the appearance of a golden metallic, increasing the commercial value.

Hereinafter, a modification of the embodiment described above will be described.

(1) As shown in Figure 3, the shape-retaining peripheral wall 6 is connected to the outer peripheral wall 7.
The lid 2 is extended further downward to increase the interval for opening the lid, making it easier to open the lid 2.

(2) As shown in FIG. 4, the locking fitting part 4, which has an angular cross section, is internally fitted into the fitted part 5, which has an angular cross section.

(3) As shown in FIG. 5, the guide portion/locking fitting portion 4 having a 3-shaped cross section is fitted and locked into the fitting portion 5 which is flared toward the end.

Since the present invention is configured as described above, it has the following effects.

The narrow opening in the center of the packaging container [one inner edge forms a locking fitting part and a fitting part on the lid and the container body, respectively, so you can just hold it between the skewers of your left and right hands and push it. , the lid can be fitted easily and quickly, and the lid can be efficiently closed in a manner that prevents it from coming off.

Moreover, on the outer circumferential side, the lid fits smoothly without interfering with the container body due to the guiding action of the shape-retaining peripheral wall.

In other words, the lid can be placed on the container body very easily.

Moreover, since the locking fitting part is fitted into the fitted part in a non-removable manner, there is no fear that the lid will come off even when packaging containers containing gas mats are hung vertically and displayed in a store.

In addition, since there is a space between the lower edge of the shape-retaining peripheral wall and the outer peripheral wall for opening the lid, you can easily put your finger on the shape-retaining peripheral wall of the lid from here, and the force required to open the lid with your fingers is reduced. Since the force is increased by the lever principle, the locking fitting part can be easily separated from the fitted part, so that the lid can be opened easily and quickly.
