  However, an overcap for a cup for over-the-counter sales cannot be directly used as an overcap for a cup beverage.

  When this is diverted to a cup having a sealing lid, it is necessary to remove and reattach the overcap when opening, and an opening device for opening the sealing lid is also required. In addition, in the case of a cup beverage adjusted and sold by a beverage manufacturer, there is a seal lid that covers the opening at the upper end of the cup in order to put it on the distribution line, so means for opening the seal lid is required when drinking However, when the contents are heated, the opening means must not come into contact with the opening means when the internal pressure of the cup rises and the seal cover swells, and the seal cover should not be damaged. In addition, when the contents are hot hot drinks or colored drinks, the operation of opening the seal lid is particularly smooth and smooth to prevent accidents where the contents undulate due to vibration during opening and overflow from the cup. It is desirable that it can be performed.

Although it is possible for a cold beverage to use a straw as an opening device, it is dangerous to drink a hot beverage, so it cannot be used.
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 comes into contact with the seal lid to make an incision, but these auxiliary jigs have the cutter blade pointed downward toward the seal lid, so the seal lid is swollen and the blade edge There is a risk of damaging the seal lid when touching.

  Further, the seal lid is initially opened at the peripheral portion, and is sequentially cut toward the center and opened. 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 jig shown in Patent Document 3 has a complicated structure such as a support member made of a porous member and is expensive, and has a simpler structure and a lower cost. Development of an opening assist jig that can be individually attached is desired.

  Because of this, it is possible to easily and quietly and smoothly form the drinking mouth and air inlet on the seal lid for cup beverages adjusted by the manufacturer, and also open the opening jig without the risk of damaging the seal lid when not opened. Is intended to provide.
