As shown in FIG. 1, the upper lid B includes a mounting tubular portion 5 that fits in a liquid-tight state with the flange portion 2 of the container body A, a peripheral wall 6 that is erected on the upper portion of the mounting tubular portion 5, and a peripheral wall 6. The top surface wall 7 is provided continuously on the inner circumference and is arranged above the sealing sheet 3.
A long substantially rectangular opening S that extends 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 portion 10 defined by an L-shaped groove 9 from the opening side surface 8. An opening blade C is provided.

The opening blade C has a substantially plate-like shape with the radial direction as the longitudinal direction as a whole, and the opening blade C has a cutting blade 11 that bends downward in the front part and fingers in the rear part so that the fingers can easily enter the lower surface. The gripping portion 12 is formed to be slightly higher, and both side end surfaces 13 are separated from the top surface wall 7 by a slight gap from the opening side surface 8 of the opening S.
The opening blade C has a blade portion 14 having a cutting blade 11 and an operation portion 15 having a grip portion 12 in front of the support portion 10 provided near the center in the longitudinal direction via a connecting mechanism described later. Are linked together.
Note that the grip portion 12 may have any shape as long as it can be easily grasped with fingers, and a hole for inserting fingers may be provided, and if the gap with the opening S is sufficiently large for inserting fingers. The entire operation unit 15 may have a flat plate shape.

The connecting mechanism of the opening blade C is provided on both sides of the opening blade C in the width direction, and includes a flexible deformable elastic plate 17 that connects a lower portion of the rear end of the blade portion 14 and a lower portion of the front end of the operating portion 15, and the elastic plate 17. It is composed of a pressing portion 16 provided on the side of the blade portion 14 and is integrally formed.
In this embodiment, the pressing portion 16 is provided on the blade portion 14 side of the elastic plate 17, but conversely, the pressing portion 16 may be provided on the operating portion 15 side, or the blade portion 14 side and the operating portion. It may be provided on both sides of the 15 side.
Since the connecting mechanism is configured as described above, when the pressing portion 16 of the blade portion 14 and the front end pressing surface 15a of the operating portion 15 are separated from each other and the blade portion 14 and the operating portion 15 are bent, The elastic plate 17 can be deformed until the pressing portion 16 of the blade portion 14 and the front end pressing surface 15a of the operating portion 15 contact each other, and the pressing portion 16 of the blade portion 14 and the front end pressing surface 15a of the operating portion 15 are 2 is in contact with each other, as shown in FIG. 2 (b), the linearly extended blade portion 14 and the operation portion 15 can be moved together.
Note that the connecting mechanism may be any mechanism as long as it has a predetermined strength and the blade portion 14 and the operating portion 15 can be in a bent state and an extended state as described above.

  When molding the opening blade C, as shown in FIG. 1 (b), the operating portion 15 is substantially horizontal, while as shown in FIG. 3 (a), the peripheral wall 6 and the blade portion shown by a solid line. In order to secure a distance d2 with the blade 14, the blade portion 14 is molded in a state of being inclined downward from the elastic plate 17 of the connecting mechanism.

As shown in FIG. 1, a pair of support portions 10 are provided outwardly from both end surfaces 13 in the vicinity of the center in the longitudinal direction of the opening blade C, and the pair of support portions 10 each have a thin hinge at the front upper end portion. It is rotatably connected to the top wall 7 by a portion 20.
In this embodiment, the hinge portion 20 is connected to the top wall 7 at the front upper end of the support portion 10. However, if the hinge blade 20 allows the opening blade C to rotate, the hinge portion 20 is not necessarily in front of the support portion 10. It does not need to be arranged at the rear side, and may be arranged at the rear side of the support portion 10.

A locking projection 21 is provided on the blade front end face 14a, and a locking rib 22 that horizontally projects with a predetermined length is formed on the opening front surface 18 of the top wall 7, and the upper lid B is opened after being molded. When the blade portion 14 is lifted up when the blade C is set in the opening S, the locking projection 21 is engaged with the locking rib 22 facing the front of the locking projection 21.
The locking projection 21 and the locking rib 22 constitute a locking portion of the present invention, and in this embodiment, the projections provided on the blade front end face 14a and the opening front face 18 are locked together. However, the blade front end face 14a and the opening front face 18 may be provided with a protrusion on either one and the other may be provided with a recess, or the protrusion may be provided on only one of them. It may be frictionally engaged with the other.
As described above, as the locking portion that locks the blade portion 14 and the opening front surface 18, as long as it can be locked to the opening front surface 18 of the opening S after molding the opening blade C, various locking portions can be used. It is possible to adopt a locking form.

In the operating portion 15 of the opening 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 erroneously applied to the operating portion 15. The opening blade C is prevented from rotating carelessly by dropping the container.
In this embodiment, the pair of weakening pieces 23 provided on both side end faces 13 are provided to prevent the unintentional rotation of the opening blade C. However, the top face wall facing the opening S is not limited to both side end faces 13. The weakening pieces 23 may be provided at appropriate positions of 7, and only one piece may be provided instead of the pair.

Further, on the lower surface of the operation portion 15, there is provided a cylindrical cutting blade cylinder 24 whose tip is cut obliquely.
Further, a cover cap (not shown) which is detachably attached to the upper lid B can be attached to the cup container with lid to prevent malfunction of the opening blade C before opening and keep the inside of the upper lid B clean.

Next, a use mode and an operation effect of the present embodiment will be described with reference to the drawings.
As shown in FIG. 1, the upper lid B and the opening blade C are manufactured by integral molding while the operating portion 15 is substantially horizontal while the blade portion 14 is inclined downward from the elastic plate 17 of the connecting mechanism. It
The opening blade C molded in the state shown by the solid line in FIG. 3 (a) lifts the front portion of the blade portion 14 and causes the elastic plate 17 to bend and deform, thereby causing the blade portion to move as shown in FIG. 3 (b). The locking protrusion 21 of the blade front end face 14 a can be engaged with the locking rib 22 of the opening front face 18 in a range in which the pressing portion 16 of 14 and the front end pressing surface 15 a of the operating portion 15 do not contact each other.
As a result, as shown in FIG. 2A, the unsealing blade C has a pair of fragile weakening pieces 23 formed between the both end surfaces 13 of the grip portion 12 and the opening side surface 8 facing the both end surfaces 13. In addition, since the peripheral wall 6 is close to the cutting blade 11 to prevent accidental hand contact, the opening blade C is kept in the state before opening without being rotated carelessly. It is supposed to be.

Next, in order to open the cup container with the lid, the operator grasps the gripping portion 12 with his / her fingers and pulls up the operating portion 15 from the state shown in FIG. 2A, and the side end surfaces 13 of the opening blade C and the top wall 7 are opened. The weakening piece 23 provided between the weakening piece 23 and the opening side surface 8 is broken, and the operating portion 15 starts rotating around the hinge portion 20 as a fulcrum while deforming the hinge portion 20 via the support portion 10.
Then, the operation portion 15 bends and deforms the elastic plate 17 as the connecting mechanism, and the front end pressing surface 15a contacts the pressing portion 16 of the blade portion 14, and the blade portion 14 and the operation portion 15 are linearly extended. In the integrated state, as shown by the solid line in FIG. 3C, the locking projection 21 of the blade front end face 14a is disengaged from the locking rib 22 of the opening front face 18, and the opening blade C is hinged. Starting to rotate around the portion 20 as a fulcrum, as shown in FIG. 2B, the cutting blade 11 pushes the sealing sheet 3 to open it.

After that, when the operation portion 15 is operated in the pushing-down direction so as to return it to the original position, the blade portion 14 tries to return the elastic plate 17 of the coupling mechanism to the state at the time of molding, and therefore is shown by a solid line in FIG. 3C. As described above, when the pressing portion 16 of the blade portion 14 and the front end pressing surface 15a of the operating portion 15 that have been in contact with each other start to separate from each other, the blade portion 14 bends the opening blade C with the elastic plate 17 as a fulcrum. To go.
Further, as the operation unit 15 is pushed down, as shown in FIG. 1B, the hinge unit 20 eliminates the deformation caused by the rotation of the operation unit 15, and thereafter the user releases the hand. Also, since the operating portion 15 in the horizontal state and the blade portion 14 in the downwardly inclined state are in the bent and stable state, it is possible to prevent the cutting blade 11 from being lifted up.

As described above, in the cup container with a lid of the present embodiment, even when the length from the hinge portion 20 of the opening blade C to the cutting blade 11 is brought close to the peripheral wall 6, as shown by the solid line in FIG. By molding the portion 14 in a state of being inclined downward with respect to the operation portion 15, it is possible to secure a sufficient distance d2 between the blade portion 14 and the peripheral wall 6, and it is possible to reduce the load on the mold. .
Further, the opening position of the sealing sheet 3 by the opening blade C is as shown in FIG. 3C, the cutting blade 11 shown by the solid line of this embodiment has a peripheral wall more than the cutting blade 31 shown by the two-dot chain line of the conventional example. Since it can be close to 6, the remaining amount of the contents can be reduced.
Further, since the upper lid B can be integrally molded with the opening blade C with synthetic resin, the container can be molded easily and can be a clean container.

Since the cup container with a lid of the present embodiment has an opening blade for breaking the sealing sheet on the upper lid, the container can be opened easily and cleanly, so it can be widely used as a container for filling beverages, foods, etc. You can
In particular, the cup container with a lid of the present embodiment, when pouring out the contents, the opening blade can be opened at a position closer to the peripheral wall of the upper lid, so that the beverage can be drunk with the lips directly, such as coffee or tea. It is a suitable container applied to such uses.
