Problems to be solved by the invention

However, it is not possible to divert the cover caps for power stores for over-the-counter sales as power caps for factory-adjusted beverages. If this is diverted to a cup with a seal lid, it is necessary to remove and reattach the cap when the seal lid is opened when forming a drinking mouth, and a separate opening device may be required. . Also, in the case of a factory-adjusted beverage cup, there is a seal-lid at the top of the force cup, so a means for opening the seal bottle is required when drinking. Moreover, when the contents are hot hot drinks or colored drinks, the operation of opening the seal lid is particularly quiet in order to prevent accidents where the contents undulate due to vibration during opening operation and overflow from the forceps. It is desirable that it can be performed smoothly.

There are those described in Patent Document 1 as an opening device that forms a drinking mouth by incising the seal lid, but in these opening devices, the force cutter is attached to the overcap attached to the upper end of the forceps via the hinge. The cutter swings and comes into contact with the seal lid to make an incision. However, the seal lid also needs an air hole that allows air to pass through to improve the dispensing property of the contents, so it is necessary to take measures such as forming a large opening, resulting in the formation of a mouthpiece. It took a lot of power to operate.

The applicant has also proposed a new overcap (Patent Document 2).

This newly proposed overcap has an incision member with a cutting blade hinged to the top plate, and operates the finger-holding member to push the incision member into the seal lid to incise and make an incision. The hole is opened, and the outlet and the air hole can be formed with extremely simple operation, which is also very safe.

However, although this newly proposed overcap has an excellent effect in terms of opening operability compared to the conventional overcap, the procedure and method of operation are difficult to communicate to consumers. I found a problem.

The present invention has been made in view of the circumstances as described above, and it is easy to form an outlet and an air hole, and the structure is simple. The method is also intended to provide an overcap that is easy to understand and understand.

Means for solving the problem

Corresponding to this purpose, the overcap of the present invention is

An overcap for a sealing container in which an upper end opening is attached to a sealing container closed with a sealing lid and the sealing lid is cut open,

The overcap is.

An overcap body that can be attached to the sealing container and has a perforation formed in a part of the top plate, and an overcap body that is integrally formed in the perforation via a hinge on the overcap body. And at least one dissecting member displaceable

The incision member includes a blade member capable of incising the seal lid, and a finger hook member protruding at a certain angle with the blade member,

When the finger hook member is operated to displace the incision member to incise the seal ridge, a gap formed between the top plate of the overcap body and the incision member is a liquid or air flow hole. It is characterized by that.

Another overcap of the present invention is an overcap for a sealing container that is attached to a sealing container whose upper end opening is closed by a sealing lid and incises the sealing lid, The overcap is

When the finger cover member is operated to displace the incision member and the seal lid is incised, a gap formed between the top plate of the overcap body and the incision member becomes a liquid or air circulation hole,

The lower end of at least a part of the projecting portion having a wall-like rib that descends downward along the edge of the perforation and supported by the top plate, the cutting member projecting downward from the top plate The position is the same as or higher than the position of the lower end of the rib. Another overcap of this invention is

An overcap for a sealing container, in which an upper end opening in the vertical direction is attached to a sealing container closed with a sealing lid, and the sealing lid is cut open,

The overcap has a mounting skirt that can be attached to the sealed container and a cover having a top plate that is substantially perpendicular to the vertical direction and covers the upper end opening of the container.

A perforation is formed in the cover, and an incision member that is formed integrally with the top plate via a hinge at the edge of the perforation and is rotatable through the perforation with the hinge as a rotation center is provided. The cutting member includes a cutting blade capable of cutting the seal lid, and a cutting blade holding member formed by protruding the cutting blade;

A standing wall that rises upward from the vicinity of the proximal end near the hinge of the cutting blade holding member, a vicinity of the distal end of the standing wall and the other end of the standing wall are connected to the hinge, and the cutting member is rotated. A finger hook member capable of receiving a pressing force to move,

The cutting blade holding member and the finger hook member are each at a predetermined angle with a center line of the container, and when the finger hook member is rotated into the hole, the edge of the hole and the edge of the hole A gap through which liquid or air can flow is formed between the outer edge of the finger hook member

It is characterized by that.

The invention's effect The overcap according to claim 1 has an incision member for incising the seal lid, but the incision member has a finger hook member solid on the blade member in addition to the blade member, so that the operation of the blade member is easy. As a result, it is easy to form a mouth and an air hole. Since the cutting member is integrated with the overcap body, the overcap structure is simplified. In the incision operation, the finger-holding member reaches the perforation, but it is not necessary to insert the finger into the perforation so that the size of the perforation does not need to be so large and the size of the liquid passage is excessively large. Since there is nothing, the flow rate can be limited in hot beverages.

Further, when the finger hook member protruding above the blade member is provided, the operation of the blade member is further facilitated.

In the overcap described in claim 2, since the blade member protrudes above the top plate and further has a finger hook member protruding above the blade member, the operation of the blade member is further facilitated.

In the overcap according to claim 3, as the blade member, a cutting blade member capable of cutting the seal lid, a stab blade member capable of piercing the seal lid, and a pressing blade member capable of pushing off the seal lid, Can be selected according to the characteristics of the mouth and air hole.

In the overcap according to claim 4, since the blade member is a hinge that is continuous with the overcap body using a line-like hinge, a strap-like hinge, or a leaf spring-like hinge, the blade member according to the characteristics of the drinking mouth and the air hole The movement can be selected.

In the overcap according to claim 5, since the cutting blade member is connected by a line hinge and the stab blade member is connected by a strap-like hinge or a leaf spring-like hinge, it is possible to give each blade member an optimum movement. it can.

In addition, when two or one blade member is used, it can be selected according to the characteristics of the mouth and air holes, so that the mouth and air holes can be easily formed.

In the overcap described in claim 6, a liquid or air flow passage is formed between the perforation edge of the top plate and the edge of the finger hook member, so that it is suitable for hot liquid such as hot coffee. Therefore, the flow rate can be restricted and it is safe.

In the overcap described in claim 7, since the through-hole formed in the finger hook member serves as a liquid or gas passage, flow restriction is further facilitated. In the overcap according to claim 8, since the incision member is positioned after the incision by the locking unevenness and the depression, the drinking operation is stabilized.

In addition, when the ridge that is raised above the top plate is formed around the periphery of the top plate so that the incision member does not protrude above the ridge, the ridge is guarded. This makes it difficult to operate the cutting member.

According to the invention described in claim 9, the overcap described in claims 1 to 8 can be used without any trouble. That is, in the overcap according to any one of claims 1 to 11, when the stab blade member is attached by a strap-like hinge, the sharpness of the stab blade member is obtained when the overcap is attached to the seal container. The tip may be closest to the sealing lid. In this case, the overcap is heated at the store, etc., and the sealing lid is swollen. The seal member is close to the tip of the stab blade, for example, if it is dropped or if the seal container is turned upside down and the contents push the seal member and bulge it outward. If it appears, the strap-like hinge or leaf spring-like hinge will operate due to the impact of dropping, and the piercing blade member will inadvertently pierce the seal member and open. There will be fear. However, the improved overcap according to claim 9 has a strap-like hinge on the inner surface of the overcap that has a strap-like hinge or a protective rib that is equal to or higher than the tip position of the stab blade in a normally stopped state. By providing it at the strap base portion of the hinge, it is possible to avoid contact between the seal lid and the stab blade member and prevent the seal lid from being inadvertently opened.

In addition, when the cutting blade member, which is the cutting member, is attached to the overcap body by the line-shaped hinge, if the hinge line that serves as the rotation center of the cutting blade member during the cutting operation is provided close to the seal lid, Although the operability of the operation can be improved, if the installation position of the hinge line is lowered (closed to the seal lid side) in this way, the hinge line comes closer to the seal lid. However, since the hinge line is thin, it is difficult to withstand the drop impact. In particular, if the impact at the time of dropping is concentrated on the hinge line (stress concentration), the hinge line is likely to break. In addition, even if the gravity of the content liquid acts on the hinge line via the seal lid when dropped, the hinge line may break. However, the improved overcap described in claim 9 can prevent the hinge line from being damaged by avoiding contact between the seal lid and the cutting blade member by the protective rib arranged around the hinge line.

In addition, when the rib is formed around one edge or a part of one edge of the perforation, contact between the cutting member and the sealing lid can be surely avoided.

Further, when the protective ribs are formed so as to surround the line hinge or the stab blade member, it is possible to reliably avoid contact between them and the seal lid.

The overcap described in claim 10 has an incision member for incising the seal lid, and the incision member has a finger hook member fixed to the blade member in addition to the cutting blade holding member on which the cutting blade is formed. Since it is formed so as to make a predetermined angle with the center line of the container, the blade member can be operated easily as in the conventional product without increasing the size of the incision member so that the mouthpiece, Air holes can be easily formed. Since the cutting member is integrated with the overcap body, the structure for forming the overcap is simplified. It is easier for the user to 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, if a perforation that serves as a drinking mouth is formed near the outflow guide wall that rises at the periphery of the top plate, the contents can be drunk very easily. It is easier for the user to 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 the overcap according to claim 11, since the tilt angle of the finger hook member is 90 ° or less, the outflow guide wall portion having a predetermined height is easy to push down the finger hook member and has a predetermined height. In addition, the finger hook member can be guarded, and the blade member can be separated from the seal lid before the force incision to keep the blade member from damaging the seal lid.

In addition, when the cutting blade is provided close to the adjacent point between the perforation and the outflow guide wall, the hole of the seal lid to be incised is aligned with the tip of the perforation, and the outflow of the contents is smooth.

In the overcap described in claim 12, since the posture of the incision member is maintained in the perforation by the return prevention stopper, the incision member does not get in the way during drinking.

In addition, when the finger hook member that has entered the perforation covers the cutting blade holding member from above, the appearance of the overcap when drinking can be made functional and good after opening.

In the overcap according to claim 13, since the stopper piece projects inward from the edge of the perforation and interferes with the finger-holding member that has reached the perforation, the position where the finger-holding member is flush with the perforation Is ensured, and the shape of the outlet of the contents is constant and stable, so that the flow of the contents is stabilized. In addition, when the outflow guide wall has a single wall structure, the mouth feel as a drinking mouth is good, and it is possible to prevent the occurrence of a liquid reservoir during pouring.

In the overcap according to claim 14, since the raised portion guards the incision member, the breakage portion of the incision member can be prevented.

In the overcap described in claim 15, since the air introduction hole forming cutting blade is provided on the lower surface of the cutting blade holding member, when the cutting blade member is pushed down as an operation of cutting the seal lid, splash is prevented at the same time. An air introduction hole can be formed.

The overcap according to claim 16 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 contents can be smoothly poured out. Can do.

In addition, when an air flow passage is formed in the stab blade member, air can smoothly flow into the cup even when the stab blade member is pierced into the seal lid.

In the overcap according to claim 17, since the entrance at the upper end of the air flow passage of the stab blade member is formed outward, the pressure can be safely released even if a splash phenomenon occurs. be able to.

In the overcap according to claim 18, since the stab blade member is supported by the leaf spring and positioned at either the top dead center or the bottom dead center, the position of the stab blade can be easily confirmed, Therefore, it can be easily confirmed whether air holes are formed or not.

In the overcap according to claim 19, since the catching lip is provided on the upper surface or the lower surface of the incision member, the rigidity of the incision portion is increased, and the movement of the finger hook member can be well transmitted to the blade edge.

In the overcap described in claim 20, since the finger hook display mark is provided on the finger hook member, the incision operation can be easily performed without fail.

The overcap according to claim 21 has an incision member for incising the seal lid, and the incision member has a finger hook member fixed to the blade member in addition to the cutting blade holding member on which the cutting blade is formed. Since it is formed so as to form a predetermined angle with the center line of the container, the blade member can be operated easily as in the conventional product without excessively increasing the size of the cutting member. Mouth and air holes can be easily formed. Since the cutting member is integral with the overcap body, the structure for forming the overcap is also simplified. It is easier for the user to guess and understand the direction in which the finger hook member is pushed down, and the incision operation of the seal lid is easy. Brief Description of Drawings
