  However, the cover cap for cups for over-the-counter sales cannot be directly used as an overcap for cup beverages. When this is diverted to a cup having a seal lid, it is necessary to remove and reattach the overcap when opening, and an opening device is also required. In the case of a factory-adjusted beverage cup, a sealing lid is present at the upper end of the cup, so that means for opening the sealing lid is required when drinking. Moreover, when the contents are hot hot drinks or colored drinks, the operation of opening the seal lid is particularly smooth and smooth to eliminate accidents where the contents spill out of the cup due to vibration at the time of opening. It is desirable that it can be performed.

  As an auxiliary jig for incising the seal lid to form a drinking mouth, there are those described in Patent Documents 2 and 3, but in these jigs, the cutter is connected to the overcap attached to the upper end of the cup via a hinge. The cutter swings and contacts with the seal lid to make an incision.

  The incised mouth is small at the initial opening around the seal lid and large at the center of the seal lid at the end of the incision, so a sufficient amount will flow into the lips unless the cup is tilted too much. Absent.

  In particular, the opening assisting jig disclosed in Patent Document 3 has a top plate (12) for the purpose of completely and smoothly opening a sealing lid made of a film in which the opening edge of the cup-type container is adhered. The notch part (16) is formed in this, and it has the structure which provided the support member which has a cutting blade part (30) so that a displacement was possible. The support member (22) is a porous member, and is formed in a fan shape having a horizontal inner end (22a) and an arc-shaped outer end (22b).

  The inner end 22 a is connected to the vertical support wall 18 of the top plate 12 via a hinge 24, and the outer end 22 b is connected to the inclined inner wall 20 of the top plate 12 via a bridge 26.

  However, the opening assisting tool disclosed in Patent Document 3 has a complicated structure such as a support member made of a porous member, and has a high cost. The development of an opening aid that can be attached to the skin is desired.

  Because of this, it is possible to easily and quietly and smoothly form a drinking mouth and air inlet on the seal lid of a cup beverage adjusted by the manufacturer, and it can be used as a mouthpiece when drinking. An object of the present invention is to provide a cup-shaped container opening assisting jig.

Corresponding to this purpose, the cup-type container opening assistance jig of the present invention is a cup-type container opening auxiliary jig to be attached to a cup-type container having an incisible seal lid for closing the upper end opening,
An overcap that can be liquid-tightly attached to a cup-type container, and a cutter that is displaceably connected to the overcap and that can incise the seal lid,
The overcap has a liquid passage through which liquid contents can flow and an air passage through which air can flow as a common passage or as another passage,
The cutter is connected to the overcap by a reversing hinge. When the overcap is mounted on the cup-type container, the cutting blade is sealed from the reference position where the cutter is not in contact with the seal lid. The incision position for incising the lid is displaceable by inversion of the inversion hinge.

In the opening aid for a cup-type container according to claim 1, the cutter is connected to the overcap body by a reversing hinge, and is displaced only in two positions: a reference position that is not in contact with the seal lid and an incision position in which the seal lid is opened. Since it takes a fixed posture, there is no accident that it touches the seal lid and damages it when not incised,
Further, since the seal lid is not completely incised at the time of incision, and the incomplete incision is not caused, the drinking mouth can be sized according to a plan suitable for suitable outflow of the content liquid.

In addition, since the incision operation only has to be pushed down linearly with fingers, the incision operation is very simple, the incision operation can be performed smoothly and smoothly, and the content liquid is not vibrated.
The cutter that has completed the incision operation enters the inside of the overcap and is held at the position of the inside of the overcap by the inversion hinge, so that the cutter does not hit the lips and become an obstacle when drinking.

  In the opening assistance jig for cup-shaped containers according to claim 2, since the shape of the cutter blade corresponds to the shape of the drinking mouth formed by the incision, the incised drinking mouth is always It becomes the shape as designed and the content flow rate as designed can be obtained.

  In the opening assistance jig for cup-shaped containers according to claim 3, since the reversing hinge is an all-around hinge, the positioning of the cutter is reliable.

  In the opening assistance jig for cup-shaped containers according to claim 4, since the cutters of various shapes, types, and various support types can be used in combination, the opening assistance jig can be easily designed.

  In the opening aid for cup-type containers described in claim 5, since the cutter itself serves as a drinking mouth for drinking the contents, the structure of the overcap can be simplified.

  In the cup-type container opening assisting jig according to the sixth aspect, since the cutting blade of the cutter is made up of a large number of small sharp cutting blade pieces, the incision of the seal lid is extremely smooth.

  In the opening aid for cup-type containers described in claim 7, the cutter is provided with reinforcing ribs or pleats to increase the rigidity, so that the incision of the seal lid is very smooth.

  In the opening assistance jig for cup-shaped containers described in claim 8, since the cutter is configured as a separate member from the overcap, the range of selection of materials for the cutter can be widened.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings showing the best mode for carrying out the invention.
1 and 2, 1a is the opening assisting jig of the present invention, and the opening assisting jig 1a is used by being attached to the upper end of the cup-type container 2.

  A flange 3 is formed around the upper end of the cup-shaped container 2, and the inside of the cup-shaped container 2 is opened to form an open opening 4. The open opening 4 is a film-like sealing lid 5 heat-sealed to the flange 3. Closed with. This seal lid 5 is an object of incision by the opening assisting jig 1a of the present invention.

  The opening assisting jig 1a includes an overcap 6 that can be attached to the cup-type container 2 and a cutter 7 that is supported by the overcap 6 so as to be displaceable. The cutter 7 and the overcap 6 are connected via an inversion hinge 8.

  The material of the overcap 6 is made of plastic such as polypropylene, paper, or composite material. For example, if the material is made of plastic, injection molding or the like can be employed.

  The cutter 7 is made of the same material when configured integrally with the overcap 6, and is made of the same material or different materials when configured as a separate member.

  The overcap 6 has a cover 11 covering the upper end of the cup-shaped container 2 and an attachment skirt 12 for attaching the cover 11 to the cup-shaped container 2 through the shoulder 13 and the center line of the opening assisting jig 1a. Concentric and continuous in 14 directions. The cover 11 has a cylindrical tube portion 15 and a top plate 16 that closes the upper end thereof.

  The attachment skirt 12 has a locking part 19 protruding around the center line 14 in the direction of the center line 14, and this locking part 19 cooperates with the shoulder 13 when the overcap 6 is attached to the cup type container 2. The flange 3 and the overcap 6 are fixed by sandwiching the flange 3 of the cup-type container 2.

  At this time, the lower surface of the shoulder 13 and the upper surface of the flange 3 are in liquid-tight contact, and the inner surface of the mounting skirt 12 and the outer peripheral end surface of the flange 3 are in liquid-tight contact. The tool 1a and the cup-shaped container 2 can be liquid-tightly mounted.

  A cutter 7 is attached to the top plate 16 of the overcap 6. That is, an oval depression 17 is formed in a portion near the center of the circular top plate 16.

  The oval recess 17 is eccentric with respect to the center line 14 of the circular top plate 16 and is offset to some side. As a result, an annular flat surface 18 formed by the top plate 16 is formed around the recess 17 like a bank of the recess 17.

  As a result of the eccentricity of the recess 17, the cylindrical mounting cylinder 21 falls on the portion 18 a having the narrowest width, depending on the position in the circumferential direction of the annular plane 18. A cutter 7 is connected to the lower end portion of the mounting cylinder 21 through an inversion hinge.

  In this embodiment, the overcap 6, the reverse hinge 8, and the cutter 7 are integrally formed. The cutter 7 has a cylindrical shape and has a liquid passage 25 along the center line 14. The upper end 26 of the cutter 7 is connected to the inner peripheral edge 27 of the reversing hinge 22.

A cutting edge portion 28 is formed at the lower end of the cutter 7. A cutting blade 31 is formed on the cutting blade portion 28 with a sharp tip facing downward. The cutter 7 may be a cylindrical body having a non-circular cross section such as an elliptical cylinder or a polygonal cylinder as long as the liquid passage 25 can be formed.
The cutting blade portion 28 may be configured by the single annular cutting blade 31 as described above, but in addition to this, as shown in FIG. 4, along the displacement direction which is the direction of the center line 24 of the cutter 23. A plurality of cutting blade pieces 33 arranged with a slit 32 formed therebetween may be formed, or, as shown in FIG. 5, the lower end of the cutting blade portion 28 of the cutter 7 is formed of a fine cutting blade piece 33b. The blade 31 may be configured, and further, the cutting blade 31 is disposed so as to be inclined with respect to the center line 24 so that when the cutting blade 31 cuts the seal lid, the force is concentrated on the cutting portion. Also good.

  In addition, as shown in FIG. 5, the cutter 7 may be reinforced by providing ribs 35 or pleats along the direction of the center line 24 on the inner peripheral surface or outer peripheral surface of the cutter 7. Further, as shown in FIG. 6, the cutter 7 may be configured such that the base portion 34 and the cutting blade portion 28 are formed as separate members, and the cutting blade portion 28 is formed in a separate process and attached to the base portion 34.

  The cutter 7 is connected to the overcap 6 via a reversing hinge 22. The reversing hinge 22 has an annular plate shape, and is connected to the upper end 26 of the cutter 7 at the inner peripheral edge 27 via an inner bent portion 38, and overcaps at the outer peripheral edge 41 via an outer bent portion 42. 6 to the attachment cylinder 21. However, in addition to the annular plate shape, the inversion hinge is configured in a non-circular and polygonal ring plate shape according to the above-described various shapes of the cutter.

  When a force is applied in the direction of the center line 24, the reversing hinge 22 is reversed with the outer bent portion 42 as a center by elastic deformation, and a normal position 43 shown in FIG. 2 and a reversing position 44 shown in FIG. Can be displaced in two positions.

  When the reversing hinge 22 is in the normal position 43, the cutting blade 31 of the cutter 7 is in a position isolated from the seal lid 5, and when the reversing hinge 22 is in the reversing position 44, the cutting blade 31 of the cutter 7 holds the seal lid 5. The changing position of the cutter 7 by the reversal of the reversing hinge 22 is adjusted so as to be a completely incised position.

The operation of the opening assisting jig 1a configured as described above is as follows.
The opening assisting jig 1a is attached to the upper end of the cup-shaped container 2 in a state where the contents are filled and the opening opening at the upper end is closed by the seal lid 5. If the opening assisting jig 1 a is placed on the upper end of the cup-shaped container 2 and pressed slightly downward, the flange 19 of the cup-shaped container 2 is placed between the engaging portion 19 of the mounting skirt 12 of the overcap 6 and the shoulder 13. 3 is mounted in a liquid-tight manner.

  Next, as an operation of incising the seal lid 5 of the cup-shaped container 2, when the cutter 7 is pushed in the direction of the center line 24 from above, the reversing hinge 22 is reversed, and accordingly the cutter 7 is lowered and the sealing lid 5 is lowered. , The cutting blade 31 cuts the seal lid 5, and the outlet 45 is formed in the seal lid 5.

  In this state, when the cup-shaped container 2 is tilted with the lip applied to the sandwiched width portion 18a of the top plate 16 of the overcap 6 as a drinking operation, the contents flow out through the outlet 45 where the contents are incised and the liquid passage 25 of the cutter 7. Can drink. At this time, the breathing air also flows through the liquid passage 25 of the cutter 7 in the reverse direction and flows into the cup-type container 2.

In this opening assist jig 1a, the cutter maintains a fixed position and posture by the action of the reversing hinge 22, and even when the contents are drunk, it does not get in the way of the lips and the liquid passage 25 of the cutter is the contents. Since it functions as a fixed guide to the contents, the flow of contents is stable and smooth.
7 to 9 show an opening assisting jig 1b according to another embodiment of the present invention. The opening assisting jig 1b can cut two holes in the seal lid 5 of the cup-shaped container 2, and correspondingly, the cutter is cut into the seal lid 5 in that the cutters 7a and 7b are provided. This is different from the opening assisting jig 1a having one hole (outlet 45) and one cutter 7.

  That is, the opening assisting jig 1 b includes two cutters 7 a and 7 b on the overcap 6. The cutters 7 a and 7 b have substantially the same structure as the cutter 7. The opening assisting jig 1b forms an outlet 45 for contents in one of the two cutters 7a and 7b and the seal lid 5, and forms an air inlet 46 for breathing with the other cutter 7b. can do.

In this way, when the outlet and the air inlet are formed separately, a large amount of air is introduced through the air inlet to facilitate breathing, so that smooth outflow of the contents is possible even if the outlet is small. . Since the shape of the air inlet 46 formed in the seal lid 5 may be different from the shape of the outlet 45, it is needless to say that the configuration of the cutter 7b may be different from the configuration of the cutter 7a.
As is apparent from the above description, according to the present invention, a drinking mouth and an air inlet can be easily and quietly and smoothly formed on the seal lid, and used by being attached to a cup container as a mouthpiece for drinking. An opening assisting jig for a cup-shaped container that can be obtained can be obtained.
