The cup container with a lid according to the present embodiment includes a container main body A and an upper lid B that is mounted so as to cover the mouth 1 of the container main body A. The upper lid B is integrally provided with an opening blade C.
In the following description, it is assumed that the upper direction is “up”, the lower direction is “lower”, the left direction is “front”, and the right direction is “rear”, as viewed in FIG.

As shown in FIG. 2, the container main body A has a sealing sheet 3 on the flange portion 2 provided around the periphery of the mouth portion 1 in order to seal the inside of the container after the contents are filled from the mouth portion 1. It is stuck.
In addition, although the drinks, such as coffee and tea, are preferable as a content with which the container main body A is filled, various contents, such as foods other than a drink, can also be filled and utilized.

As shown in FIG. 1, the upper lid B includes a mounting cylinder portion 5 that fits in a liquid-tight state with the flange portion 2 of the container main body A, a peripheral wall 6 that is erected on the top of the mounting cylinder portion 5, And a top wall 7 arranged on the inner periphery and disposed above the sealing sheet 3.
The top wall 7 is formed with a long, substantially rectangular opening S that traverses in the radial direction. 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 opening blade C is provided.

The opening blade C has a substantially plate shape as a whole with the radial direction as the longitudinal direction. The opening blade C has a cutting blade 11 that bends downward at the front and a finger at the rear so that the fingers can easily enter the lower surface. The both side end surfaces 13 are spaced apart from the opening side surface 8 of the opening S by a slight gap.
The unsealing 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 via a coupling mechanism described later. Are connected.
The grip portion 12 may have any shape as long as it can be easily grasped with a finger, and may be provided with a hole for inserting the finger, and if the gap with the opening S is sufficiently large to insert the finger. The entire operation unit 15 may be flat.

The connecting mechanism of the unsealing blade C is provided on both sides in the width direction of the unsealing blade C. It consists of a pressing portion 16 provided on the blade portion 14 side, 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 operation portion 15 side, or the blade portion 14 side and the operation portion. It may be provided on both sides on the 15 side.
Since it is configured as described above, the connecting mechanism is configured such that the pressing portion 16 of the blade portion 14 and the front end pressing surface 15a of the operation portion 15 are separated and the blade portion 14 and the operation 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 operation portion 15 come into contact with each other, and the pressing portion 16 of the blade portion 14 and the front end pressing surface 15a of the operation portion 15 2 are in contact with each other, as shown in FIG. 2B, the blade portion 14 and the operation portion 15 that are linearly extended can be moved together.
Note that the coupling mechanism may be any mechanism as long as it has a predetermined strength and the blade portion 14 and the operation portion 15 can be bent and extended as described above.

  When molding the opening blade C, the operation portion 15 is substantially horizontal as shown in FIG. 1B, whereas the blade portion indicated by the peripheral wall 6 and a solid line as shown in FIG. 3A. In order to ensure the distance d2 with respect to 14, the blade portion 14 is molded in a state inclined downward from the elastic plate 17 of the coupling mechanism.

As shown in FIG. 1, a pair of support portions 10 project outwardly from both side end surfaces 13 near the longitudinal center of the opening blade C, and the pair of support portions 10 are thin hinges at the front upper end portions, respectively. A portion 20 is connected to the top wall 7 so as to be rotatable.
In this embodiment, the hinge portion 20 is connected to the top wall 7 at the front upper end portion of the support portion 10. However, the hinge portion 20 is not necessarily in front of the support portion 10 as long as the opening blade C is allowed to rotate. It is not necessary to be disposed in the rear, and it may be disposed behind the support portion 10.

A locking protrusion 21 is provided on the blade front end surface 14a, and a locking rib 22 protruding in the horizontal direction with a predetermined length is formed on the opening front surface 18 of the top wall 7 and is opened after the upper lid B is molded. When the blade 14 is lifted upward when setting the blade C in the opening S, the locking protrusion 21 is engaged with a locking rib 22 facing the front of the locking protrusion 21.
The locking projection 21 and the locking rib 22 constitute the locking portion of the present invention. In this embodiment, the locking protrusion 21 and the locking rib 22 are locked by the protrusions provided on the blade front end surface 14a and the opening front surface 18. However, either one of the blade front end surface 14a and the front opening 18 may be provided with a protrusion and the other may be provided with a recess, or only one of them may be provided with a protrusion. You may make it friction-engage with the other.
As described above, as a locking portion for locking the blade portion 14 and the opening front surface 18, various types can be used as long as the opening blade C can be locked to the opening front surface 18 of the opening S after molding. It is possible to adopt a locking form.

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 surfaces 13 are used to prevent inadvertent rotation of the unsealing blade C, but the top wall facing the opening S is not limited to the side end surfaces 13. The weakening piece 23 may be provided at an appropriate place of 7, and only one may be provided instead of the pair.

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

Next, usage modes and operational effects 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 in a state where the operation portion 15 is substantially horizontal, while the blade portion 14 is inclined downward from the elastic plate 17 of the coupling mechanism. The
The unsealing 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 bends and deforms the elastic plate 17, thereby forming the blade portion as shown in FIG. 3 (b). The locking protrusions 21 of the blade front end surface 14a can be engaged with the locking ribs 22 of the opening front surface 18 within a range where the 14 pressing portions 16 and the front end pressing surface 15a of the operation portion 15 do not contact each other.
Thereby, as shown to Fig.2 (a), the unsealing blade C forms a pair of breakable weakening pieces 23 between the both side end surfaces 13 of the holding part 12 and the opening side surface 8 which faces both side end surfaces 13. In addition, since the peripheral wall 6 is close to the cutting blade 11 and prevents the hand from being accidentally touched, the opening blade C is kept in the state before opening without rotating carelessly. It is supposed to be.

Next, in order to open the cup container with the lid, when the finger is applied to the gripping part 12 and the operation part 15 is pulled upward from the state shown in FIG. 2A, both side end faces 13 of the opening blade C and the top wall 7 The weakening piece 23 provided between the opening side surface 8 and the opening portion 8 is broken, and the operation portion 15 starts rotating around the hinge portion 20 as a fulcrum while deforming the hinge portion 20 via the support portion 10.
Then, while the operation unit 15 bends and deforms the elastic plate 17 as the coupling mechanism, the front end pressing surface 15a comes into contact with the pressing unit 16 of the blade unit 14, and the blade unit 14 and the operation unit 15 extend linearly. As shown by the solid line in FIG. 3C, the locking projection 21 of the blade front end surface 14a is detached from the locking rib 22 of the opening front surface 18, and the opening blade C is hinged. As shown in FIG. 2 (b), the cutting blade 11 pushes the sealing sheet 3 and opens it as shown in FIG. 2 (b).

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 shown by a solid line in FIG. 3C because the elastic plate 17 of the coupling mechanism attempts to return to the state at the time of molding. As described above, when the pressing portion 16 of the blade portion 14 that has been in contact with the front end pressing surface 15a of the operation portion 15 begins to separate, the blade portion 14 bends the opening blade C with the elastic plate 17 as a fulcrum. To go.
When the operation unit 15 is further pushed down, as shown in FIG. 1B, the hinge unit 20 is released from the deformation caused by the rotation of the operation unit 15, and then the user releases the hand. However, since the operating portion 15 in the horizontal state and the blade portion 14 in the downward inclined state are in a bent and stable state, the cutting blade 11 can be prevented from lifting upward.

Thus, even if the length from the hinge part 20 of the opening blade C to the cutting blade 11 is brought close to the peripheral wall 6, the cup container with a lid according to the present embodiment has a blade as shown by the solid line in FIG. By molding the portion 14 in a state inclined downward with respect to the operation portion 15, a sufficient distance d2 between the blade portion 14 and the peripheral wall 6 can be ensured, and the load on the mold can be reduced. .
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 in this embodiment is more peripheral than the cutting blade 31 shown by the two-dot chain line of the conventional example. 6, the remaining amount of contents can be reduced.
Furthermore, since the upper lid B can be integrally molded with the opening blade C from a synthetic resin, it can be molded easily and cleanly.

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, since the cup container with a lid of this embodiment can be opened at a position where the unsealing blade is closer to the peripheral wall of the upper lid when the contents are poured out, it is a beverage such as coffee or tea with a direct lip. It is a suitable container applied to uses such as.
