In addition, although the drinks, such as coffee and tea, are preferable as a content filled with the container main body A, it can fill and use various contents, such as foods other than a drink.

The upper lid B is connected to the flange portion 2 of the container body A in a liquid-tight state, the peripheral wall 6 standing on the upper portion of the mounting cylinder portion 5, and the inner periphery of the peripheral wall 6. The top surface wall 7 is arranged above the sealing sheet 3.
A substantially rectangular opening S that is long in the radial direction is formed in the top wall 7, and the opening S is connected to the top wall 7 by a support 10 that is partitioned from the opening side 8 by an L-shaped groove 9. An unsealing blade C is provided.

The unsealing blade C has a substantially plate shape as a whole with the radial direction as the longitudinal direction, and is formed slightly higher so that the cutting edge 11 bent downward at the front end and the finger can easily enter the lower surface at the rear end. The both side end surfaces 13 are separated from the top wall 7 by a slight gap in the opening S.
The opening blade C is in front of the support portion 10 provided in the vicinity of the center in the longitudinal direction, and the blade portion 14 having the cutting blade 11 and the operation portion 15 having the grip portion 12 are connected by an elastic inversion hinge mechanism. ing.
The grip portion 12 may be any shape that can be easily grasped by a finger, and may be provided with a hole for inserting a finger. If the gap with the opening S is sufficiently large to insert a finger, the entire operation portion 15 is flat. It does not matter if it is

The elastic reversing hinge mechanism for connecting the blade portion 14 and the operation portion 15 includes an elastic plate 16 provided at the center in the width direction of the opening blade C, and a pair of first hinge portions 17 provided at two locations on both sides of the elastic plate 16. And is integrally molded.
In this embodiment, the first hinge portions 17 are provided at two locations on both sides of the elastic plate 16, but conversely, the first hinge portion 17 is provided at the center and a pair of elastic plates 16 are provided on both sides thereof. Alternatively, each of the plurality of elastic plates 16 and the first hinge portion 17 may be provided at appropriate positions.

As shown in FIG. 3 (a), the elastic plate 16 is connected to the rear end upper part of the blade part 14 at the front end part 16a, and is connected to the front end upper part of the operation part 15 at the rear end part 16b. Is uniform and the cross-sectional shape is a dogleg shape.
The first hinge portion 17 is formed as a thin portion at the upper end portion that connects the blade portion 14 and the operation portion 15.
In this embodiment, the elastic plate 16 is connected at the upper end portion of the blade portion 14 and the operation portion 15, and the first hinge portion 17 is connected at the upper end portion of the blade portion 14 and the operation portion 15, As shown in FIG. 5B, the elastic reversing hinge mechanism is such that the first hinge portion 17 includes at least the front end portion 16a and the rear end portion 16b of the elastic plate 16, as shown in FIG. What is necessary is just to cross the ZZ line to connect at the time of rotation.
Further, the cross-sectional shape is not limited to this embodiment as long as the elastic plate 16 has a predetermined strength and can be elastically bent.

As shown in FIG. 2A, a pair of support portions 10 project outward from both side end surfaces 13 near the center in the longitudinal direction of the opening blade C.
As shown in FIG. 3 (b), the pair of support portions 10 are connected to the top wall 7 by a thin second hinge portion 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. However, the second hinge portion 20 is not necessarily arranged in front of the support portion 10 as long as it allows the opening blade C to rotate. Instead, it may be arranged behind the support portion 10.

On both side end surfaces 13 of the opening blade C, a fixed projection 21 is provided in front of the blade portion 14, and the front of the fixed projection 21 is chamfered.
A locking rib 22 that protrudes in the vertical direction with a predetermined length is formed on the opening side surface 8 of the top wall 7 that faces the front of the fixed protrusion 21. When the opening blade C rotates in the opening direction, the fixed protrusion 21 is engaged. It comes to match.
The locking rib 22 constitutes the locking portion of the present invention. As the locking portion, various locking modes can be used as long as it can prevent the opening blade C from rotating in the return direction. It is possible to adopt.

In the operation portion 15 of the opening blade C, a pair of breakable weakening pieces 23 are formed between the side 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 opening blade C is prevented from rotating carelessly by dropping the container.
In the present embodiment, the pair of weakening pieces 23 provided on the side end faces 13 is used as a means for preventing inadvertent rotation of the opening blade C. However, the top wall 7 facing the opening S is not limited to the side end faces 13. The weakening pieces 23 may be provided at appropriate positions of the above, and only one may be used instead of the pair.
Further, a cylindrical cutting cylinder 24 whose tip is cut obliquely is provided on the lower surface of the operation unit 15.

In this embodiment, the upper lid B is integrally formed of a synthetic resin, but the present invention is not limited to this, and other materials and manufacturing methods may be used.
Further, a cover cap (not shown) that can be attached to and detached from the upper lid B is attached to the cup container with the lid, so that the malfunction of the opening blade C before opening can be prevented, and the inside of the upper lid B can be kept clean.

Next, usage modes and operational effects of the present embodiment will be described with reference to the drawings.
As shown in FIG. 2, the unsealing blade C in a horizontal state before unsealing has a pair of weakened pieces 23 that can be broken between the both side end faces 13 of the grip portion 12 and the opening side faces 8 facing the both end faces 13. In addition to being formed, the peripheral wall 6 is close to the cutting blade 11 and prevents the hand from being touched by mistake, so that the unsealing blade C can be maintained in a horizontal state without rotating carelessly. ing.

When a finger is applied to the gripping part 12 from the state shown in FIG. 2 and the operation part 15 is pulled upward, the weakening piece 23 provided between the both side end faces 13 of the opening blade C and the opening side face 8 of the top wall 7 is 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 reversing hinge mechanism and the first hinge portion 17, the opening blade C is connected to the second portion via the support portion 10. While the hinge part 20 is deformed, the second hinge part 20 starts rotating around the fulcrum, and the cutting blade 11 pushes the sealing sheet 3 to open it.
Then, as shown in FIG. 4A, the unsealing blade C further rotates, and the fixed protrusion 21 of the blade portion 14 slidably contacts the locking rib 22 formed on the opening side surface 8, and further sealed. The opening of the sheet 3 is expanded.
At this time, the user feels a click feeling due to the fixed protrusion 21 getting over the locking rib 22 and can confirm that the opening operation is in the final stage.

Thereafter, when the operation portion 15 is operated in the push-down direction so as to return to the original position, the blade portion 14 is prevented from rotating because the fixed projection 21 is engaged with the locking rib 22 as shown in FIG. In addition, the operation unit 15 rotates about the second hinge unit 20 as a fulcrum and bends the opening blade C with the first hinge unit 17 as a fulcrum while being deformed so as to narrow the elastic plate 16.
As shown in FIG. 3A, the elastic plate 16 is not elastically deformed with the front end portion 16a and the rear end portion 16b being most open when the blade portion 14 and the operation portion 15 are in the extended state. When the operation portion 15 rotates downward and the blade portion 14 and the operation portion 15 are bent, the elastic plate 16 is elastically deformed and the front end portion 16a and the rear end portion 16b tend to narrow.
Further, when a force is applied to the operation unit 15, as shown in FIG. 5 (b), the first hinge unit 17 generates a Z-Z line connecting the front end 16a and the rear end 16b of the elastic plate 16. Since the blade portion 14 and the operation portion 15 are in a bent and stable state even after the user releases their hands by bending the elastic plate 16 beyond the elastic plate 16 side, the elastic plate 16 tends to spread. It is possible to prevent the operation unit 15 from rotating upward against the restoring force.

Thus, the cup container with a lid of the present embodiment rotates the unsealing blade C to open the sealing sheet 3 and then holds the blade portion 14 at the position rotated downward and is connected to the blade portion 14. Since only the operation portion 15 can be held in the return state before the opening operation by the elastic reversing hinge mechanism, after the container is opened, the blade portion 14 of the opening blade C becomes an obstacle when the contents are poured out. There is no.
Even when the user puts lips on the upper lid B and drinks the contents, the operation unit 15 of the opening blade C does not get in the way and is difficult to drink.
Further, since the upper lid B can be integrally formed with the opening blade C from a synthetic resin, it can be easily molded and can be a clean container.

The cup container with a lid of the present embodiment can be opened easily and cleanly because the upper lid has an opening blade that breaks the sealing sheet, so that it can be widely used as a container for filling beverages, foods, etc. Can do.
In particular, the cup container with a lid of the present embodiment has a simple structure so that the opening blade does not get in the way when the contents are poured out. It is a container suitable for application to.
