変形部を係合させたものである。``Prior art'' Once the storage distribution outlet is opened, it is difficult to return to the original closed state, so-called a seal that guarantees that no opening occurs during the product distribution process. As a cap, for example, the device disclosed in Japanese Unexamined Utility Model Publication No. 55-6275 is known. This invention involves tightly fitting an annular wall hanging down from the lower surface of the top plate of a sealing stopper into the spout of a stopper body that is irremovably fitted into a bottle opening, and then turning the entire lower edge of the ring wall into a spout. A heated rod inserted into the inside of the spout from below is used to forcibly expand and deform the spout, and the deformed portion is engaged with the lower surface of the peripheral edge of the spout.

て硬化することで更に増大する。"Problems to be Solved by the Invention" The synthetic resin sealing cap of the conventional example described above requires cooling time because it is forcibly expanded by pressing a hot rod into the lower part of the ring wall 7 and being thermally deformed. The cooling time becomes a loss time, which increases the working time, and since it is difficult to control the temperature of the hot rod, the ring wall 7 may melt and weld to the plug body due to the heat. There were cases where the sealing stopper became discolored due to heat and spoiled its appearance. Furthermore, since the ring wall of the sealing stopper that is thermally deformed returns to its original shape somewhat due to heat radiation after heating, a gap is likely to be formed between the ring wall and the spout of the main body of the stopper, thus impairing the sealing and sealing functions. In addition, since the deformed portion is formed over the entire lower part of the ring wall, the deformed portion has a high rigidity, making it difficult to remove the sealing stopper when opening the seal. This difficulty in removal is further exacerbated by the physical properties of the lower part of the ring wall changing and hardening due to heating.

るようにしたものである。 In this case, after fitting the cylindrical portion 7 of the closing plate 8 into the outflow hole 5 of the cap main body 1, a part of the outer circumferential wall portion of the lower part of the cylindrical portion 7 is cut and raised and deformed by pouring, and the deformed portion is shaped as described above. By engaging with the lower surface of the peripheral edge of the outflow hole, it has an excellent sealing function and can be easily removed.

封印キヤツプを形成させた。"Means for solving the problem" A protrusion 2 is attached to the inner surface of the peripheral wall 4 hanging from the periphery of the top wall 3, so that the protrusion 2 is irremovably fitted into the groove provided around the outer surface of the mouth and neck of the container body. At the same time, there is a cap main body 1 made of thermoplastic resin with a stored material outlet hole 5 bored in the top wall, and a cap body 1 made of thermoplastic resin with a stored material outlet hole 5 formed therein, and a cap body 1 having a larger outer diameter than the outflow hole, which is inserted onto the top wall 3 with the stored material outlet hole closed. At the same time as placing the plate part 6, the cylindrical part 7 hanging from the back surface of the plate part is tightly fitted into the outflow hole, and a part of the outer peripheral wall of the lower part of the cylindrical part is cut and raised. A sealing cap was formed by the closing plate 8 with the knob piece 9 whose cast-deformed portion was engaged with the lower surface of the peripheral edge of the outflow hole.

して嵌合出来ない。"Function" As shown in FIG. 3, the sealing cap according to the present invention tightly fits the cylindrical part 7 hanging from the back surface of the plate part 6 of the closing plate 8 into the outflow hole 5 of the main body 1 of the cap, and The upper end of the jig 10 is fitted into the cylindrical part 7, and the cylindrical body 12 fitted on the outer surface of the jig 10 and having a blade 11 on the inner periphery of the upper end is pushed up to be cut and driven. As a result, a part of the outer circumferential wall portion of the lower portion of the cylindrical portion 7 is formed into a cast deformed portion 7a, and the cast deformed portion 7a is engaged with the lower surface of the peripheral edge of the outflow hole. Moreover, if the knob piece 9 is held and pulled up, the casting deformation portion 7a is elastically deformed and the closing plate 8 can be removed. The cast deformed portion 7a interferes and cannot be fitted.

is attached to the inner surface of the lower end of the peripheral wall 4 that hangs down from the peripheral edge of the top wall 3. Further, a large storage material outlet hole 5 is bored in the top wall 3. The intermediate portion 3b between the outflow hole side peripheral wall portion 3a and the outer peripheral portion 3c of the top wall 3 is preferably made to stand up in a tapered shape diagonally upward and inward as shown in the figure.

The plate portion 6 has an outer diameter larger than that of the outflow hole, and a portion of the plate portion is formed into a knob piece 9 to protrude laterally. The lower part of the cylindrical part 7 fitted into the outflow hole is
A part of the outer circumferential wall portion is cut and raised, and the cast deformed portion 7a is engaged with the lower surface of the peripheral edge of the outflow hole.

い。"Effect of the invention" The present invention has the above-mentioned configuration, and when the knob piece 9 is pulled up, the casting deformation portion 7a is elastically deformed, so that the closing plate 8 can be removed. The outflow hole 5 of the cap main body 1 as before

価に製作することができる。 Since the cast deformed portion 7a is not thermally deformed as in the conventional case, the above-mentioned conventional drawbacks can be wiped out and the sealing effect can be enhanced. It is formed by cutting and raising a part of the outer circumferential wall of the lower part of the part 7 and deforming it by pouring, rather than deforming the entire cylindrical part as in the conventional case, so the removal of the closing plate 8 is easy. Since both the main body of the cap and the closing plate are made of thermoplastic synthetic resin, the casting deformation can be achieved by simply pushing up the bladed cylinder from below to engage the lower surface of the periphery of the outflow hole as described above. In this way, the sealing cap according to the present invention can be manufactured at low cost.
