Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reclosable cup, and provides a completely novel and easy-to-open cup that has never existed before.

[Conventional technology]

Conventionally, as shown in FIGS. 1 and 2, aseptically packaged cups, etc., of a cup body A made of plastic or the like having a flange 1, a part of the flange 1 is extended to form a gripping piece 2. A half-cut line 3 is made in the gripping piece 2 from the lower surface side, and the cover plate 4 is heat-sealed from the flange 1 to the gripping piece 2. When opening, the gripping piece 3 is made at the outside of the half-cutting line 3. The piece 2 and the lid plate 4 are grasped and folded up in the direction of arrow P, the pinched piece 2 is cut at the half-cut line 3, and further pulled in the direction of arrow P, as shown in FIG. 3. Lid plate 4
Generally, an easy-to-open cup is used in which the cup is opened by peeling it from the flange 1, but such a conventional cup has the disadvantage that once it is opened, it cannot be reclosed.

[Problem that the invention attempts to solve]

The problem that the present invention seeks to solve is to provide a reclosable, easy-to-open cup.

[Means for solving problems]

As a result of research to solve the above problems, the inventor of the present invention has developed a device that has a flange, and a part of the flange is formed wider than the other flange area, so that part of the flange is used as a gripping piece. The cup consists of a plastic cup body and a lid plate, and the lid plate is heat-sealed to the flange surface of the plastic cup body. By providing a thin line part and a thin line part reaching the outer edge of the flange from both ends of the thin line part, by gripping the gripping piece and pulling it upward, the thin line part along the inner edge of the flange and the thin line part can be removed. A part of the flange can be cut and separated from both ends along the thin line part that reaches the outer edge of the flange, and a part of the cover plate can be peeled off from the flange to open it. It has been discovered that it is possible to reclose the cut end surface of the flange portion outside the cut portion by surrounding and locking the cut end surface of the flange portion inside the cut portion, and based on this knowledge, the present invention has been developed. This is the completed version.

The reclosable cup of the present invention has a plastic cup body having a flange, a portion of the flange being wider than the other flange area, and a portion of the flange serving as a gripping piece, and a lid plate. It consists of
In a cup that is heat-sealed to the flange surface of the plastic cup body, the lid plate passes through at least the circumferential center of the wide flange area, and extends from a thin line portion along the inner edge of the flange and both ends of the thin line portion. A thin line portion is provided when the outer edge of the flange is reached.

[Effect]

The concave cut end surface of the flange part outside the cut part cut along the thin line part along the inner edge of the flange will become the convex cut end face of the flange part inside the cut part when the cover plate is returned to its original position before opening. The concave cut end surface is surrounded by and locked to the convex cut end surface.

〔Example〕

To explain one embodiment of the present invention using the diagram, the fourth embodiment is as follows.
The figure is a perspective view of the components of the reclosable cup according to the present invention.

It consists of a plastic cup body A having a flange 1 and a part of the flange 1 made wider than other flange areas so that a part of the flange serves as a gripping piece 2, and a lid plate 4, The lid plate 4 is a cup that is heat-sealed to one side of the flange of the plastic cup body A, and has a curved thin line portion 5 that passes through at least the circumferential center of the wide flange area and along the inner edge a of the flange. A linear thin line portion 6 is provided from both ends of the thin line portion 5 to reach the outer edge of the flange. The thin line portion 5 along the inner edge a of the flange and the thin line portion 6 extending from both ends of the thin line portion 5 to the outer edge b of the flange are for cutting the flange 1 along the thin line portions 5 and 6 during use. Therefore, the thin wire portions 5 and 6 are formed thinner than other portions of the flange 1. Further, in order to facilitate cutting of the flange 1 along the thin wire portions 5 and 6, it is desirable to use a relatively brittle plastic such as polyvinyl chloride or polystyrene as the material of the cup body A.

In use, as shown in Fig. 5, by gripping the gripping piece 2 and pulling it upward, the thin line portion 5 along the inner edge of the flange and both ends of the thin line portion along the inner edge of the flange are attached to the outer edge of the flange. The thin line portion 6 reaching the opening is cut to open the lid plate 4. After removing the desired amount of contents, return the cover plate 4 to its original position, and the cut end surface of the outer flange portion of the thin line portion 5 along the inner edge of the flange will be aligned with the cut end surface of the inner flange portion of the thin line portion 5 along the inner edge of the flange. The top surface of the cup body A can be completely reclosed by encircling locking.

[Effect of idea]

Since the present invention has the above-mentioned structure, it can be reclosed, the contents can be dispensed, and there is no need to prepare a separate cap for re-closing, which contributes to cost savings. It has remarkable effects.

Claims (1)

[Scope of utility model registration request] It consists of a plastic cup body A having a flange 1 and a part of the flange 1 made wider than the other flange area so that a part of the flange 1 serves as a gripping piece 2, and a lid plate 4. In the cup that is heat-sealed to the first flange surface of the plastic cup body A, the lid plate 4 passes through at least the circumferential center of the wide flange area and is connected to the thin line portion 5 along the inner edge a of the flange. Thin line parts 6 are provided that reach the outer edge of the flange from both ends of the thin line part 5, and by gripping the gripping piece 2 and pulling it upward, the thin line part 5 along the inner edge a of the flange and the thin line part 5 are removed. A part of the flange can be cut and separated along the linear thin line part 6 reaching the outer edge b of the flange from both ends, and a part of the cover plate 4 can be peeled off from the flange to open the cover plate 4. By returning to the original position before opening, the cut end surface on the lid plate 4 side cut along the thin line portion 5 along the inner edge a of the flange and the cut end surface on the outside of the flange portion on the plastic cup A side are surrounded and locked. A reclosable cup characterized in that it is configured so that it can be reclosed by opening the cup.
