Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a container with a simple sealing function.

``Prior Art'' Conventionally, containers such as ice cream containers or similarly simple food containers have not been provided with a sealing function. Some containers have lids fixed to the container body by heat welding.

``Problems to be solved by the invention'' In the case of the above-mentioned thermal welding, welding equipment is required and assembly is also large-scale.

The object of the present invention is to obtain a container with a simple sealing function that can be formed by simply pushing the lid into the container body manually.

"Means for Solving Problems" In the present invention, an outward flange 2 is provided from the upper edge of the container body 1, and an engaging shaft 4 having a large diameter head 3 extends from at least both upper surfaces of the outward flange 2. . It has a hole 7 through which it can pass, and this hole 7
It has a structure in which engaging holes 9, 9 are formed on both inner sides, through which a pair of spring strips 8, 8, shaped like the seams of a baseball, are curved and protrude toward the other side.

"Operation" In the above, the lid 5 is closed after storing the required contents in the container body 1. In this case, the engaging holes 9, 9 of the lid 5 are aligned with the engaging shafts 4, 4, and the lid 5 is closed. A pair of spring strips 8, 8 are forced onto the engagement shaft 4 through the large diameter head 3 so that the engagement shaft 4 passes through the hole 7 of the engagement hole 9. Then, the spring strips 8, 8 are returned to the small diameter shaft portion position on the lower surface of the head 3, and engaged with the engagement shaft 4.

In this state, there is no way to push the spring strips 8, 8 apart against their elasticity, so the lid 5
In order to open the lid, the lid 5 must be forcibly pulled down at the engaging holes 9, and the spring strips 8, 8 must be cut. That is, a sealing function can be obtained.

"Example" In this example, a food container for storing food such as ice cream is shown as a container.

The container body 1 has a round, deep-dish shape, and the outward flange 2 has a step-like shape in which the outer half is higher, and the lid 5 is designed so that it can be automatically closed and installed in a predetermined position. Both sides of this outward flange 2 are slightly expanded in an arc shape, and engagement shafts 4, 4 are provided at these portions.

Although the engaging shafts 4, 4 are formed into a cylindrical shape by projecting the outward flange 2 itself upward, they may be solid bodies. The heads 3 of the engagement shafts 4, 4 have an inclined circumferential surface that gradually becomes thicker downward, and have a rounded top and an angular lower circumferential edge, and have a pair of spring strips. It has a shape that allows it to be easily pushed and inserted between 8 and 8, and cannot be removed once it has penetrated. Incidentally, it is more effective if the lower end peripheral edge of the head 3 of the engagement shaft 4 is made into an acute angle as shown in FIG. Further, in the illustrated example, the engaging shafts 4, 4 are provided at two locations on both sides, but they may be provided at three locations at 120 degree intervals, or at four locations at 90 degree intervals.

The outward flange 6 of the lid 5 has a stepped shape that corresponds to the outward flange 2 on the container body 1 side, and knobs 10 are provided on both sides of the engaging holes 9. , 10, the lid 5 is forcibly pulled up and opened so that the spring strips 8, 8 can be cut.

Each of the above parts is molded and manufactured from synthetic resin material.

"Effects of the Invention" As described above, in the present invention, an engaging shaft 4 having a large-diameter head 3 on the outward flange 2 is provided on the container body 1 side.
On the lid 5 side, an engaging hole 9 with a pair of spring strips 8, 8 like the seams of a baseball is formed in the outward facing flange 6, and when the lid 5 is attached, this engaging hole 9 is opened.
, the engagement shaft 4 is forcibly expanded between the spring strips 8, 8.
Since the spring strips 8, 8 are returned and engaged at the small diameter part of the lower surface of the head 3, a sealing function that cannot be opened unless the spring strips 8, 8 are broken is obtained, and quality assurance is achieved. becomes possible. However, the sealing function of the lever can be formed by simply pushing it manually, and no special forming equipment is required, so it is convenient and easy to form.
