In the present embodiment, the elastic plate 16 is connected at the upper end of the blade 14 and the operation unit 15, and the first hinge 17 is connected at the upper end of the blade 14 and the operation unit 15, The connection site does not necessarily have to be the upper end, and as shown in FIG. 5 (b), in the elastic reverse hinge mechanism, the first hinge 17 at least includes the front end 16a and the rear end 16b of the elastic plate 16. What is necessary is just to cross at the time of turning on the Z-Z line to be connected.
Further, as long as the elastic plate 16 has a predetermined strength and can be elastically bent, the cross-sectional shape is not limited to this embodiment.

As shown to Fig.2 (a), in the longitudinal direction center vicinity of the opening blade C, a pair of support part 10 is protrudingly provided outward from the both-sides end surface 13. As shown in FIG.
As shown in FIG. 3 (b), the pair of support portions 10 is continuously connected to the top wall 7 by the thin second hinge portions 20 at the front upper end portion.
The second hinge portion 20 is connected to the top wall 7 at the front upper end portion of the support portion 10, but if it allows rotation of the opening blade C, the second hinge portion 20 needs to be always disposed in front of the support portion 10 Instead, it may be disposed behind the support portion 10.

On both end surfaces 13 of the unsealing blade C, a fixing projection 21 is provided in front of the blade portion 14, and the corner is chamfered in front of the fixing projection 21.
A locking rib 22 which protrudes vertically in a predetermined length is formed on the opening side 8 of the top wall 7 facing the front of the fixed protrusion 21. When the unsealing blade C rotates in the unsealing direction, the fixed protrusion 21 engages. It is supposed to match.
Although the locking rib 22 constitutes the locking portion of the present invention, various locking forms may be used as long as the locking portion can prevent rotation of the unsealing blade C in the return direction. It is possible to adopt.

In the operation portion 15 of the unsealing blade C, a pair of breakable weakening pieces 23 are formed between the both end surfaces 13 and the opening side surface 8 facing the both end surfaces 13, and a force is applied to the operation portion 15 by mistake. The container is dropped, and the opening blade C is prevented from rotating carelessly.
In the present embodiment, the pair of weakening pieces 23 provided on the both end faces 13 is used to prevent the careless rotation of the unsealing blade C, but the top wall 7 faces the opening S as well as the both end faces 13. The weakening pieces 23 may be provided at appropriate places in the above, or only one may be provided instead of a pair.
Further, on the lower surface of the operation unit 15, a cylindrical cutting blade cylinder 24 whose tip is obliquely cut is provided.

In the present embodiment, the upper lid B is integrally molded of a synthetic resin, but the present invention is not limited to this, and other materials and manufacturing methods may be used.
In addition, a cover cap (not shown) that can be attached and removed to the upper lid B can be attached to the lidded cup container to prevent a malfunction of the opening blade C before opening and keep the inside of the upper lid B clean.

Next, usage modes and effects of the present embodiment will be described with reference to the drawings.
As shown in FIG. 2, the opening blade C in the horizontal state before opening has a pair of breakable weakening pieces 23 between the end faces 13 on both sides of the grip 12 and the opening side 8 facing the end faces 13 on both sides. Since it is formed and the peripheral wall 6 is close to the cutting blade 11 to prevent it from being touched by mistake, the unsealing blade C is maintained in the horizontal state without rotating inadvertently. ing.

From the state shown in FIG. 2, when the operating portion 15 is pulled up by putting fingers on the gripping portion 12, the weakening pieces 23 provided between the both end surfaces 13 of the opening blade C and the opening side surface 8 of the top wall 7 are broken. Since the blade portion 14 and the operation portion 15 are connected in an extended state by the elastic plate 16 as the elastic reverse hinge mechanism and the first hinge portion 17, the unsealing blade C is secondly connected via the support portion 10. While the hinge portion 20 is being deformed, the rotation is started around the second hinge portion 20, and the cutting blade 11 pushes the sealing sheet 3 to open it.
Then, as shown in FIG. 4 (a), the unsealing blade C is further rotated, and the fixed projection 21 of the blade portion 14 slides over the locking rib 22 formed on the opening side surface 8 and gets over, and further sealing is performed. Expand the sheet 3 opening.
At this time, it is possible to confirm to the user that a click feeling is transmitted due to the fixing projection 21 getting over the locking rib 22, and that the opening operation is at the final stage.

Thereafter, when the operation portion 15 is operated in the push-down direction so as to return the original position, the blade portion 14 is engaged with the locking rib 22 and blocked in rotation, as shown in FIG. The operation unit 15 rotates the second hinge 20 as a fulcrum, and bends the unsealing blade C with the first hinge 17 as a fulcrum while deforming the elastic plate 16 so as to narrow it.
As shown in FIG. 3A, when the blade portion 14 and the operation portion 15 are in the extended state, the elastic plate 16 is not elastically deformed in a state in which the front end portion 16a and the rear end portion 16b are most opened. When the operation portion 15 rotates downward and the blade portion 14 and the operation portion 15 bend, the elastic plate 16 elastically deforms and the front end portion 16a and the rear end portion 16b tend to narrow.
Furthermore, when a force is applied to the operation portion 15, as shown in FIG. 5B, the first hinge portion 17 is a Z-Z line connecting the front end portion 16a and the rear end portion 16b of the elastic plate 16 By bending to a point where it enters the elastic plate 16 side after that, even if the user releases the hand, the blade portion 14 and the operation portion 15 are in a bent and stable state, so that the elastic plate 16 may spread. Against the restoring force, it is possible to prevent the operating unit 15 from rotating upward.

As described above, the lidded cup container of the present embodiment rotates the unsealing blade C to break open the sealing sheet 3 and holds the blade portion 14 at the position rotated downward and is connected to the blade portion 14 Since only the operation unit 15 can be held in the return state before the opening operation by the elastic reverse hinge mechanism, the blade portion 14 of the opening blade C interferes with the dispensing of the contents after the container is opened. There is no
In addition, even when the user puts a lip on the upper lid B and drinks the contents, the operation unit 15 of the opening blade C does not hit the face and does not interfere with drinking.
Furthermore, since the upper lid B can be integrally molded with the unsealing blade C by a synthetic resin, the upper lid B can be easily molded into a clean container.

The lidded cup container of the present embodiment has an opening blade for breaking the sealing sheet on the upper lid, so that the container can be opened easily and cleanly, so that it can be widely used as a container for filling beverages, foods and the like. Can.
In particular, the lidded cup container of the present embodiment has a simple structure such that the opening blade does not interfere with the pouring of the contents, and thus the use of a drink such as coffee or black tea which is directly worn with a lip Is a container suitable for application to
