JP2002002740A - Container with easily peelable lid seal - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a container in which a force required to peel a lid seal can be reduced, and there is no fear of spilling the liquid content, etc., when the lid seal is unsealed. SOLUTION: The lid seal of the container can be unsealed by a small force using the principle of leverage not by peeling off the lid seal but by winding the lid seal by a winding plate 3 and a lever 4.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container formed of a synthetic resin or the like and mainly used for storing condensed milk, syrup, etc., and which is hermetically sealed with a lid seal by means of a so-called heat seal or the like.

[0002]

In the conventional container, it is necessary to apply a large force to both fingertips in order to peel off the lid seal, and there is a possibility that the content liquid may be spilled. An object of the present invention is to solve this inconvenience by providing a container in which the lid seal can be peeled off with a small force.

[0003]

Means for Solving the Problems Instead of peeling off the lid seal, the lid seal is rolled up with a small force by the principle of leverage by winding it up with a plate-like small piece for winding it up and its knob or lever. Configure the container to allow

[0004]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A take-up plate 3 and a lever 4 formed on an extension of a flange 2 of a container body 1 shown in FIG. I do. The lid seal 7 covers the sealing ring 8 for sealing the contents of the container body and reaches the winding plate and is firmly joined to the fixing area 9.

When the lid seal 7 is opened, a force is applied to the tip of the lever 4 to break the connecting portion 6, and then the winding plate 3 is rotated by half while bending and breaking the connecting portion 5. If the rotation is further continued, the lid seal 7 can be peeled off from the sealing ring 8 as shown in FIG.

Guide projections 10 shown in FIG. 3 are formed at both ends of the take-up plate 3, and are guides for accurately guiding the take-up direction when the take-up plate starts to rotate beyond half a rotation when opened. .

FIG. 4 shows a winding width expanding portion 11 for expanding the winding width when the winding plate 3 rotates more than one rotation.

[0008]

According to the present invention, since the lid seal can be peeled off with a small force by the principle of leverage as compared with the conventional container, there is no danger of spilling the contents. In addition, the present invention can be implemented without making significant changes to the manufacturing process and materials of this type of conventional container,
Industrially beneficial.
