The blade holding portion 25 forms an angle smaller than 90 ° formed by the center line of the cup-shaped container 2 and the perforation 22 formed in the innermost portion of the recess 21 of the overcap body 6. When the finger hook member 26 rotates around the hinge 10 to a position that substantially coincides with the perforation 22, a content outlet 28 is formed between the edge of the front end of the perforation 22.

  An index 31 indicating an operation procedure or an operation method is provided on the surface above the finger hook member 26. The index 31 is configured by unevenness or a plane figure, and can be visually recognized or touched by an operator.

  As shown in FIG. 10, the cutting blade 24, the cutting blade holding member 25, the finger hook member 26, and the standing wall 74 are reinforced by mutual reinforcement ribs 32, 33, and 34.

  The peripheral wall 15 of the overcap body 6 is formed around the periphery of the top plate 16, and the configuration of the portion 35 facing the tip of the perforation 22 is different from that of the other portion 36. The portion that faces the mouthpiece is a mouthpiece that touches the mouth, and this portion has a liquid passage 37 that has a bowl-like shape in which the inner peripheral surface is recessed outward from the other portion, and from the other peripheral wall 15 Also, a high outflow guide wall 38 is formed. The outflow guide wall 38 has a solid single wall structure. On the other hand, the other portion 36 has a uniform double-wall structure having a uniform thickness over the entire circumference and a hollow double structure.

  From the side edge of the perforation 22, a stopper piece 41 projects in a tongue shape inwardly. The stopper piece 41 can interfere with the finger hook member 26 that has reached the perforation 22, and the interference prevents the finger hook member 26 from passing through the perforation 22 and entering the cup-shaped container 2 side.

  The operation of the overcap 1a configured as described above is as follows.

  As shown in FIGS. 11 and 12, when the finger hooking member 26 of the incising member 7 is pushed up with a finger according to the index 31, the finger hooking member 26 and the cutting blade 24 integrated therewith rotate around the hinge 10.

When the cup-shaped container 2 is tilted with the mouth in this state, the content liquid flows out from the outlet port 28 and is poured out through the gap 42 between the edge of the perforation 22 and the outer edge of the finger hook member 26. It is guided to the liquid passage 37 of the spilled guide wall 38 and sent out for drinking.

  13 to 21 show an overcap 1b according to a second embodiment of the present invention.

  In the overcap 1b according to the second embodiment, an air hole forming member 51 only for forming an air circulation hole is provided separately from the cutting member 7 of the overcap 1a according to the first embodiment. .

In other words, a circular opening 52 is formed in the top plate 16, and the air hole forming member 51 is supported through the support member 53 therein. The air hole forming member 51 has a push button portion 54 at the top, and a piercing needle 55 projects downward from the lower surface of the push button portion 54. The piercing needle 55 has a sharp cutting edge 56 that can be opened by piercing the seal lid 5 at the lower end. Further, a groove is formed on the side surface of the puncture needle 55 from the lower end to directly below the push button portion 54, and this groove constitutes an air flow passage 57. The upper end portion of the air flow passage 57 is closed to form a lateral opening. The piercing needle 55 can be made hollow and the hollow portion can be used as the air flow passage 57.
The support member 53 has thin hinges 61 at both ends, and the support member 53 itself is configured to function as a leaf spring, and is formed integrally with the top plate 16 and the air hole forming member 51.

  The operation of forming air holes in the overcap 1b configured as described above is as follows.

  The air hole is formed by an operation different from the formation of the opening by the cutting member 7. If this air hole is formed, air circulates from there, so there is no need to ensure air circulation at the opening portion by the incision portion 7, so that the perforation 22 and the incision member passing therethrough can be made small.

  As the air hole forming operation, the push button portion 54 of the air hole forming member 51 is pushed down.

  The pushed-down push button portion 54 is lowered by the support member 53 having a leaf spring function being inverted, and the tip of the cutting blade 56 provided on the lower surface of the push button portion 54 pierces the seal lid and enters the container. The air hole forming member 51 maintains the posture in which the piercing needle 55 (cutting blade 56) is pierced into the seal lid, but the air flows through the air flow passage 57 formed in the piercing needle 55 and is used for air flow. A passage is formed.

In the illustrated example, since the upper end of the air flow passage 57 opens outward, even if the internal pressure in the cup container increases and a splash phenomenon occurs in which the content liquid blows out at the time of opening, the blowout is directly directed to the operator. It doesn't blow away.
The overcap 1b configured as described above has an air hole forming member having a stab blade member that can pierce the seal lid, so that the air hole can be easily formed and the content can be smoothly poured out. Can do.
In addition, since the air flow passage is formed in the piercing needle, air can smoothly flow into the cup even when the piercing needle is stuck into the seal lid.
Furthermore, since the puncture needle is supported by a support member having a leaf spring function, the posture can be stably maintained before and after piercing the seal lid. In addition, it is possible to clearly indicate to the user which posture (position) the push button 54 is in.
The air hole forming member 51 and the supporting member 57 can be used in other types of overcaps having other types of cutting members. For example, in the overcap disclosed in FIG. 1 of Patent Document 2 shown above, a strap hinge type air hole forming member using the cutting member 8 as an air hole forming member and the strap hinge 34 as a supporting member and the supporting member are the cutting members. However, instead of the strap hinge type air hole forming member and support member, a leaf spring type air hole forming member 51 and support member 57 may be used.
22 to 26 show an overcap 1c according to a third embodiment of the present invention.
The overcap 1c includes an overcap body 6c that can be attached to a cup-type container, and a cutting member 7c that is integrally connected to the overcap body 6c via a hinge 10c.
The overcap body 6c has a cover 11c covering the upper end of the cup-type container and an attachment skirt 12c for attaching the cover 11c to the cup-shaped container in the direction of the center line 14c of the overcap body 6c via the shoulder 13c. Concentrically and continuously. The cover 11c has a cylindrical peripheral wall 15c and a top plate 16c that closes the lower end thereof.
The overcap body 6c has a recess 21c above the top plate 16c at a central position, and a peripheral wall 15c that surrounds the recess 21c and rises around the center line 14c.
A perforation 22c is formed at an edge corresponding to one end of the top plate 16c in the diametrical direction just before the outflow guide wall 38c of the peripheral wall 15c. The perforation 22c is a hole used as a hole for circulating the content liquid in the cup-type container or a hole for circulating the breathing air. On both sides of the perforation 22c, the top plate 16c is raised upward to form a raised portion 23c.
The raised portion 23c is composed of a downward slope portion 71c near the outflow guide wall portion 38c and an upward slope portion 72c near the opposite side, and a boundary line 73c between the downward slope portion 71c and the upward slope portion 72c is the highest. The boundary line 73c is located on the side of the boundary between the finger hanging member 26c of the incision member 7c described later and the standing wall 74c. Both the downward slope 71c and the upward slope 72c are slightly higher in the portion near the outer peripheral wall 15c than in the portion near the inner perforation 22c.
The raised portion 23c is located along the cutting member 7c, has a function as a guard that prevents the cutting member 7c from coming into contact with other objects and being damaged, and the contents flowing out from the perforations 22c are It suppresses the flow in the lateral direction and exerts the function of concentrating the flow in the oral cavity of the drinker.
A cutting member 7c is disposed in the perforation 22c, and is connected to the top plate 16c via a hinge 10c at the base end. The hinge 10c is formed to be thin.

  The cutting member 7c can be displaced through the perforation 22c by rotating around the hinge 10c.

  The incising member 7c has a cutting edge 24c through which the seal lid 5c can be incised, a cutting edge holding member 25c from which the cutting edge 24c projects, and a standing wall that rises upward from the vicinity of the proximal end near the hinge 10c of the cutting edge holding member 25c. 74c and the standing wall 74c are connected in the vicinity thereof, and the other end is connected to the hinge, and includes a finger hook member 26c capable of receiving a pressing force for rotating the cutting member 7c.

  The cutting blade 24c protrudes downward from the lower surface of the distal end portion of the cutting blade holding member 25c. The cutting blade 24c has a sharp lower end and can cut the seal lid 5c.

The cutting edge holding member 25c has a shape substantially similar to the perforation 22c in plan view, but the size is slightly smaller than the perforation 22c, and a gap is formed between the edge of the perforation 22c when placed in the perforation 22c. Is done.
The finger hook member 26c has a plate shape, is located above the cutting blade holding member 25c, and is fixed to the cutting blade holding portion 25c through the standing wall 74 at the distal end portion. The blade holding part 25 c forms an angle smaller than 90 ° with respect to the center line of the cup-shaped container 2. When the finger hook member 26c is rotated around the hinge 10c to a position substantially coinciding with the perforation 22c, an outlet port 28c for the contents is formed between the edge of the front end of the perforation 22c.

  An index 31c indicating an operation procedure or an operation method is provided on the surface above the finger hook member 26c. The index 31c is composed of unevenness and a plane figure, and can be visually recognized or touched by the operator.

As shown in FIG. 23, the connection between the standing wall 74c and the cutting blade holding member 25c is reinforced by the reinforcing rib 32c on the upper surface of the cutting member 7c, and the cutting blade 24c and the cutting blade holding member 25c are formed on the lower surface of the cutting member 7c. The standing wall 74c and the finger hook member 26c are reinforced by the reinforcing ribs 33c and 34c.
As shown in FIG. 25, two types of stopper structures, that is, a passage prevention stopper structure 75c and a return prevention stopper structure 76c are provided between the cutting member 7c and the perforation 22c.
The passage preventing stopper structure 75c is provided with a plate-like stopper piece 77c projecting laterally from the finger hook member 26c at the base end portion of the incising member 7c. A reinforcing rib 78c is provided between the finger hook member 26c and the stopper piece 77c to connect and reinforce them.
When the incising member 7c is pushed into the perforation 22c as an incising operation, it is a stopper structure for preventing the incising member 7c from excessively passing the perforation 22c and entering the cup-type container, and a return preventing stopper structure 76c. On the contrary, the cutting member 7c pushed into the perforation 22c does not stop in the perforation 22c due to the elastic recovery of the hinge 10c, and does not return to the original direction from the perforation 22c. It is a stopper structure to prevent it.
In the passage preventing stopper structure 75c, the stopper 82c protrudes from the side surface 8c of the raised portion 23c facing the perforation 22c toward the inside of the perforation 22c. In the return prevention stopper structure 76c, the stopper 83c extends from the same side surface 81c to the inside of the perforation 22. Protrusively toward.
Both of these stoppers 82c and 83c protrude to a position where they interfere with the finger hook member 26 when the finger hook member 26 enters the perforation 22c as an incision operation.
The stopper 82c for preventing passage has a large protruding amount from the side surface 81c of the raised portion 23c, a large thickness, and a large rigidity. Therefore, even when the stopper 82c abuts on the stopper piece 77c of the incising member 7c, the stopper piece Since 77c does not get over the stopper 82c, the movement of the cutting member 7c is stopped at a position coinciding with the perforation 22c. On the other hand, the stopper 83c of the return prevention stopper structure 76c has a small protrusion amount, a small thickness, a small rigidity, and a structure that easily causes elastic bending. Therefore, when the cutting member 7c is incised, When the stopper piece 77c comes into contact with the stopper 83c for preventing return, the stopper 83c can be elastically bent so as to get over the return preventing stopper 76c and reach the position coincident with the perforation 22, but in this case, the stopper structure for preventing return is provided. Since 76c is elastically restored to its original state, the restored stopper 76c abuts against the stopper piece 77c of the cutting member 7c to prevent the cutting member 7c from returning and returning.

  As shown in FIG. 26, when the finger hook member 26c of the incising member 7 is pushed up with the finger according to the index 31c, the finger hook member 26c and the cutting blade 24c integrated with the finger hook member 26c rotate around the hinge 10c and descend, The cutting blade 24c incises the seal lid 5, and the outflow port 28c opens. When the finger hook member 26c coincides with the height of the perforation 22c, the finger hook member 26c is restrained by the stoppers 82c and 83c at the edge of the perforation 22c to maintain the posture, and the opening of the outflow port 28c is completed. When the cup-shaped container is tilted at the mouth in this state, the content liquid flows out from the outflow port 28c and is poured out through the gap 42c between the edge of the perforation 22c and the outer edge of the finger hook member 26c and can be drunk.

The overcap 1c also has an incision member for incising the seal lid. However, since the incision member has a finger hook member fixed to the blade member in addition to the blade member, the operation of the blade member is easy, and as a result, the drinking mouth The formation of air holes is easy. Since the cutting member is integral with the overcap body, the structure of the overcap is simplified. Since the overcap has an outflow guide wall that rises upward, it functions as a mouthpiece when drinking, and it is extremely easy to drink the contents. In addition, since the finger hook member fixed to the incision member is inclined at a predetermined angle, the user can easily guess and understand the direction in which the finger hook member is pushed down, and the incision operation of the seal lid is easy. .
In addition, since the tilt angle of the finger hook member is 90 ° or less, the function of pointing the direction of pushing down the finger hook member is exhibited.
Further, since a visible or tactile indicator is provided on the finger hook member, the contents of the operation can be understood more clearly. In this case, the finger hook member itself is inclined at a constant angle, and the side surface of the finger hook member provided with the index can be clearly seen from above, so that the understanding of the operation content is certain.
Furthermore, since the finger hook member covers the cutting blade holding member and only the finger hook member can be seen from above, it is possible to simplify the process of necessary operations and make the operator understand and to make the operator uneasy. Never give.
In addition, since the stopper piece protrudes inward from the edge of the perforation and interferes with the finger hook member that has reached the perforation, a position where the finger hook member is flush with the perforation is secured, and the shape of the outlet of the contents is Since it is in a constant and stable state, the content flow is stabilized.
In addition, since the outflow guide wall has a single wall structure, the mouth feel as a drinking mouth is good, and the occurrence of a liquid reservoir during pouring can be prevented.
Moreover, since the inner wall surface of the outflow guide wall is on the outer side, the inner wall surface has a bowl-like shape, and the contents can be consumed smoothly.

27 to 29 show overcaps 1d, 1e, and 1f according to the fourth, fifth, and sixth embodiments.
The features common to these overcaps 1d, 1e, and 1f are that the cylindrical peripheral wall 15 of the cover portion 11 is level over the entire circumference around the center line 14, and stretches inward from the side edge of the perforation 22. When the width of the stopper piece 41 to be extended is increased and the finger hook members 26d, 26e, 26f that have reached the perforation 22 interfere with each other, the finger hook members 26d, 26e, 26f pass through the perforation 22 and enter the cup-shaped container 2 side.
