A pair of annular seal lips 23 are concentrically provided on the outer peripheral edge portion of the lower surface of the top wall 22, and these seal lips 23 elastically contact the surface of the sealing material 2, thereby the lid main body portion. The space between the cup 20 and the cup-like container 1 is liquid-tightly sealed to prevent the beverage from leaking out.

  A drinking wall 24 is provided integrally with the top wall 22. The drinking mouth wall 24 is formed in a wall shape that protrudes upward from the top wall 22, and the protrusion height from the top wall 22 in a predetermined circumferential range (the left portion in FIGS. 1 and 2) is different. Is higher than the part. The high portion of the drinking mouth wall 24 forms a drinking mouth for the beverage that flows out of the cup-shaped container 1.

  The top wall 22 is provided with an outlet 25 for allowing the beverage to flow out from the cup-shaped container 1 to the outside. The outflow port 25 is formed as a notch hole having a predetermined width obtained by notching a part of the top wall 22, and opens along a portion of the drinking wall 24 that forms the drinking mouth. Therefore, the beverage that has flowed out of the cup-shaped container 1 can flow through the outlet 25 to the portion constituting the drinking mouth of the drinking mouth wall 24.

  The opening tool 30 is for opening the sealing material 2 of the cup-shaped container 1. The opening tool 30 includes a cutting blade member 31 and an operation piece 32.

  The cutting blade member 31 has a substantially rectangular support plate portion 31a and a cutting blade portion 31b provided integrally at the tip of the support plate portion 31a. The support plate portion 31a is vertically arranged so as to protrude upward from the top wall 22, and a lower end portion of the support plate portion 31a extends in a direction perpendicular to the support plate portion 31a (parallel to the top wall 22). The connecting portion 33 is provided integrally. Hinge portions 34 are provided on both sides of the connecting portion 33, and the cutting blade member 31 is connected to the top wall 22 by these hinge portions 34. The cutting edge portion 31b is formed in a triangular shape with a sharp tip, and is provided so as to protrude in a direction orthogonal to the support plate portion 31a. In addition, the code | symbol 31c is a rib which supports the cutting blade part 31b. The cutting blade member 31 is rotatable about the hinge portion 34, and is rotated from the initial position shown in FIGS. 1 and 2 to the opening position shown in FIGS. Can move. By rotating the cutting blade member 31 to the opening position, the sealing material 2 can be cut and opened by the cutting blade portion 31b, and an outflow hole through which the beverage can flow out can be formed in the sealing material 2.

  The operation piece 32 is a part that performs an operation for rotating the cutting blade member 31. The operation piece 32 is formed in a plate shape whose front end is divided into two forks, and has an angle different from that of the support plate portion 31a of the cutting blade member 31 (in the illustrated case, the support plate portion 31a or the outlet is gradually increased toward the upper side). Projecting obliquely upward from the top wall 22 at an angle away from 25). When the cutting blade member 31 is in the initial position, the upper end of the cutting blade member 31 and the upper end of the operation piece 32 are both lower than the upper end of the drinking mouth wall 24. A pair of locking portions 32a is provided on the distal end side of the operation piece 32, and a semicircular cutout portion 32b is formed between the locking portions 32a. The notch 32b is not limited to a semicircular shape, and may be a rectangular shape, for example. The operation piece 32 is integrally connected to the opposite side across the hinge portion 34 of the cutting blade member 31 via the connecting portion 33 on the base end side, and can be rotated integrally with the cutting blade member 31. It has become. Therefore, the user can cut and open the sealing material 2 by rotating the cutting blade member 31 from the initial position to the opening position by pulling up the operation piece 32.

  The pair of locking portions 32 a are each formed in a plate shape that bends at a predetermined angle with respect to the operation piece 32 and curves with a curvature corresponding to the curved shape of the drinking mouth wall 24. When the operation piece 32 rotates together with the cutting blade member 31 to a position where the cutting blade member 31 is set to the opening position, the pair of locking portions 32 a are locked to the upper end of the drinking mouth wall 24. At this time, for example, the pair of locking portions 32 a are in a state where they are strongly abutted against the upper end of the drinking mouth wall 24 and are fixed to the upper end of the drinking mouth wall 24 in an elastically deformed state so that the angle with respect to the operation piece 32 increases. It is said. Therefore, after the cutting blade member 31 is rotated to the opening position by the operation piece 32 to cut and open the sealing material 2, the pair of locking portions 32 a are locked to the upper end of the drinking mouth wall 24, thereby operating the operation piece. 32 can be held in the opening position. In addition, a pair of latching | locking part 32a can also be set as the structure engaged with the upper end of the drinking mouth wall 24 in the state which does not elastically deform.

  In addition, the width of the pair of locking portions 32 a of the notch portion 32 b of the operation piece 32 is wider than the width of the portion along the drinking mouth wall 24 of the outlet 25. That is, in a state where the pair of locking portions 32 a is locked to the upper end of the drinking mouth wall 24 and the operation piece 32 is held in the opening position together with the cutting blade member 31, the notch portion 32 b at a position along the drinking mouth wall 24. Is wider than the width of the portion along the drinking mouth wall 24 of the outlet 25. Therefore, the beverage that has flowed out from the cut and opened cup-like container 1 through the outlet 25 to the drinking mouth wall 24 can flow out without touching the operation piece 32.

  The top wall 22 is provided with a convex wall portion 22c that is provided in a stepped manner higher than the other portions by a pair of standing walls 22b. A portion of the convex wall portion 22c protruding from the pair of standing walls 22b with an arcuate end surface is an elastic support portion 22d, and a piercing protrusion 26 protruding downward is formed on the lower surface of the elastic support portion 22d. It is provided integrally. The elastic support portion 22d functions as a cantilever, and can be elastically deformed toward the sealing material 2 by being pushed downward. The piercing protrusion 26 has a sharp tip, and when the pressed elastic support portion 22d is elastically deformed downward by a predetermined amount, the piercing protrusion 26 may pierce the sealing material 2 and make a hole in the sealing material 2. it can.

  Next, a procedure for opening the sealing material 2 of the cup-shaped container 1 by the lid 10 with the opening tool having such a configuration will be described.

  As shown in FIGS. 1 and 2, the opening 1a of the cup-shaped container 1 is sealed with the sealing material 2 during distribution, and the cutting blade member 31 of the opening tool 30 is in the initial position. . In addition, at the time of distribution etc., you may make it mount | wear with the overcap which covers the said cover body 10 with an opening tool in the further outer side of the cover body 10 with an opening tool. By attaching such an overcap, it is possible to prevent the lid body 10 with the opening tool from becoming dirty during distribution and to make the lid body 10 with the opening tool more sanitary.

  When the operation piece 32 of the opening tool 30 is pulled up, the cutting blade member 31 rotates together with the operation piece 32 from the initial position toward the opening position. 3 and 4, when the cutting blade member 31 reaches the opening position, the sealing material 2 is cut and opened by the cutting blade portion 31b, and an outflow hole through which the beverage flows out is formed in the sealing material 2. Is done. Therefore, by inclining the cup-shaped container 1 with a mouth attached to the mouthpiece wall 24, the beverage can flow out from the cup-shaped container 1 through the outlet 25 to the mouthpiece wall 24 and drink.

  At this time, when the cutting blade member 31 rotates to the opening position, the pair of locking portions 32a of the operation piece 32 are locked to the upper end of the drinking mouth wall 24, and the operation piece 32 is held at the opening position. The operation piece 32 does not get in the way when drinking a beverage. Therefore, the lid 10 with the opening tool can be easily drinkable.

  Further, the notch 32b provided between the pair of locking portions 32a of the operation piece 32 held at the opening position has a width along the drinking mouth wall 24 of the outlet 25 at a position along the drinking mouth wall 24. Since it is formed wider than the width at the position, it is possible to make it difficult for the beverage flowing out from the cup-shaped container 1 to the drinking mouth wall 24 to touch the portion touched by the finger when the operation piece 32 is pulled up. Therefore, it is possible to drink the beverage without touching the portion touched by the finger when the operation piece 32 is pulled up, and the lid body 10 with the opening tool can be made more sanitary.

  When the cup-like container 1 to which the lid 10 with the opening tool is attached is heated by a heating device such as a microwave oven before the sealing material 2 is opened, the elastic support portion 22d is pushed down to pierce the cup-like container 1 A hole for pressure relief can be formed in the sealing material 2 by the protrusion 26. Thus, by making a hole for pressure relief in the sealing material 2 in advance before heating, it is possible to prevent the cup-shaped container 1 from rupturing due to an increase in internal pressure during heating.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above-described embodiment, the cutting blade member 31 is rotatably connected to the top wall 22 by the pair of hinge portions 34 provided on both sides of the support plate portion 31a. As long as the cutting blade member 31 can be pivotably connected to the top wall 22, for example, as shown in FIG. The cutting blade member 31 may be rotatably connected to the top wall 22 by a thin film-like hinge portion 34 provided between the both side projecting portions on the end side and the top wall 22.

  In addition, the shape of the cutting blade member 31 is not limited to the above shape, and may be any other shape as long as the sealing member 2 can be cut and opened by rotating around the hinge portion 34 as a fulcrum.

  Further, the shape of the pair of locking portions 32 a of the operation piece 32 can be variously changed as long as it can be locked to the upper end of the drinking mouth wall 24.
