PSP (Polystyrene paper) sealing paper is a sealing paper coated with sealing wax on a synthetic paper extruded in the form of thin plate of expandable polystyrene. When the PSP sealing paper is squeezed into the opening of the container, the opening of the container is sealed due to the stickiness of the sealing wax, so that the food inside the container is easily preserved.

However, in order that the sealing by the PSP sealing paper is completely performed and the airtightness of the inside of the container is maintained, the sealing paper must be squeezed at a certain pressure or higher.

However, there is no method for confirming whether or not the sealing of the conventional PSP sealing is possible except the transparency of the pressing surface. In addition, the transparency of the pressed surface indicates only that the sealing paper undergoes pressure on the pressed surface, and is not an indicator for determining whether or not the pressing is performed with a pressure equal to or higher than the pressure at which the sealing is performed, There was a problem that was not particularly clear.

Conventionally, in order to open a container sealed by a PSP sealing paper, the pressed PSP sealing paper is again peeled and opened. However, such a method has a problem that it is uncomfortable to the user, creates a non-clean appearance, and causes discomfort.

1, a lead 100 according to a first preferred embodiment of the present invention is constructed with a PSP sealing paper and a pressure sensitive paper, and the PSP sealing paper includes a synthetic paper 120 and a sealing wax layer 110 A sealing wax layer 110 is formed on the lower surface of the synthetic paper 120 formed by extruding foamed polystyrene into a thin plate shape and the developing agent film 140 is coated on the lower surface of the pressure- And the microcapsules 130 are applied. Such PSP sealing papers and pressure reducing papers are well known.

The lead sheet 100 is in the form of a laminate in which the above-described pressure-sensitive paper is laminated and adhered to the above-described PSP sealing paper, and the upper surface of the pressure-sensitive paper is stuck to the lower surface of the PSP sealing paper.

When the known PSP sealing paper is covered with the opening of the container and the pressure is applied, the airtightness can be maintained by adhering to the opening of the container by the sealing wax. However, in order to solve this problem, there is no way to confirm whether or not the sealing material is sealed. In order to solve this problem, the lead sheet 100 according to the first embodiment of the present invention adhered pressure sensitive paper to the PSP sealing paper.

The decompression paper keeps the color of its normal color while it is discolored when the pressure is applied, so that it can detect the applied pressure. When a microcapsule 130 is broken due to a pressure applied to the microcapsule 130, a coloring agent is adsorbed on the coloring film 140 to cause a reaction.

The lid sheet 100 according to the second preferred embodiment of the present invention differs from the first embodiment in the configuration of the depressurized sheet only in the lead sheet 100 according to the second embodiment, The microcapsule 130 and the starch column 160 are embedded in the colorant film 140. When the microcapsules 130 are protected by the starch pillars 160 and the pressure suitable for sealing is applied, the microcapsules 130 are broken and the coloring agent is adsorbed on the film of the developer 140, It is only discolored and can sense pressure.

The lead 100 is stuck to the case 200 in a state in which the opening is covered, and then the pressure is applied by an external force. Therefore, the bottom surface of the PSP sealing paper located below the lead paper 100, that is, the sealing wax layer 110 is pressed against the upper surface of the outer wall.

When the pressure is more than the minimum pressure at which the sealing can be performed, the decompression paper responds and discoloration occurs in the pressing portion 170. When the pressure is less than the minimum pressure, the microcapsules 130 do not break and the coloring agent does not react with the color developing agent, so that discoloration does not occur.

As shown in FIG. 3, the inner surface of the lead 100 may have an easy cut structure 180 formed thereon. The cut structure 180 is formed by irradiating a film with a laser. In the portion irradiated with the laser, the strength of the film is weak and can be easily detached.

The cut-off structure 180 in the preferred embodiment of the present invention is configured such that when a portion of the lead 100 is torn along the cut-off structure 180 with a circular closed curve structure, do.

When the inner food is discharged through the outlet formed by the easy cut structure 180 in the case of a tablet (tablet), a sphere (ring), or a capsule type medicine, it can be discharged neatly and this structure may be aesthetically pleasing.

Hereinafter, a food container according to an embodiment of the present invention will be described. FIG. 4 is an exploded perspective view showing a food container according to a preferred embodiment of the present invention, and FIG. 5 is a vertical sectional view showing a cap portion of a food container according to a preferred embodiment of the present invention.

A food container according to a preferred embodiment of the present invention comprises a lid 100, a case 200, and a cap 300. The structure of the lead pile 100 and the case 200 and the coupling relation thereof have been described above, and therefore will not be described.

5, the cap 300 is composed of a body 340 and a guide hole 320. The upper part of the body 340 is a cylindrical part and the lower part is a housing part which is provided with a peripheral edge of the inner wall near the lower end of the housing. The cap screw portion 350 is formed. On the upper surface, a pusher 311 of a punching device 310 and a punching retaining portion 322 of a guide hole 320 are formed.

The cap screw portion 350 of the cap 300 and the case screw portion 210 of the case 200 mate together with the cap screw 300, And the case 200 are combined.

When the cap 300 and the case 200 are coupled, the bottom surface of the cylindrical portion of the cap 300 is positioned near or in contact with the upper surface of the lead 100.

A guide hole 320 is formed at the center of the cylindrical portion of the cap 300. A punching retaining portion 322 is formed at an upper portion of the guide hole 320 and a spring retaining portion 324 is formed at a lower portion thereof. The diameters of the respective retaining portions 322 and 324 are smaller than the diameters of the guide holes 320. [

The punching tool 310 and the spring 330 are housed in the guide hole 320. The punching tool 310 includes a punching blade 312 having an inclined lower end and a cylindrical shape And a presser 311. The spring 330 is configured to surround the punching blade 312 with a known spring.
