As this container, a paper container such as a paper cup is generally used. After carrying the contents, the opening is sealed with a lid material such as aluminum foil for carrying.
As described above, when sealing with the lid material, the seam portion where the paper base material is overlapped remains on the top of the paper container as it is, and a step is generated, so that perfect adhesion between the lid material and the top of the paper container cannot be obtained. It was difficult to achieve a good seal.

かった。[0003] In order to improve the sealing performance of the lid material by sealing, a plastic ring formed in advance is applied to the opening of the top of the paper container by ultrasonic waves or the like, as shown in JP-B-63-24464. Paper containers bonded by means have been proposed and put into practical use. The paper container with this plastic ring has the strength of the opening and the sealing part has no steps, so not only can a good sealing performance be achieved, but also the structure considering the openability is possible, and the liquid can be filled. It was a suitable container to do. That is, the paper container,
A paper container such as a paper cup formed in advance and a plastic ring formed so as to match the opening of the paper container are combined and bonded by means of ultrasonic waves or the like to manufacture. As described above, since each member is manufactured separately and manufactured by combining them, the manufacturing process is complicated and the container is expensive. That is, the overlapping portion of the trunk of the paper container, the joining portion formed by winding the trunk and the bottom plate,
In order to protect with a resin layer made of the same molten plastic as the top part, it had to be provided as a separate member in a separate step.

チックリング付紙容器１０が知られている。Therefore, as shown in FIG. 3A, a paper container such as a paper cup is used as a container in which the top end surface 15a is exposed and the overlapping portion 11a of the body 11 can be protected simultaneously with molding. , A paper container body formed by winding and integrating a bottom plate 12 and a body 11 on both sides of which a plastic layer is laminated is placed in an injection mold, and after the mold is closed, molten plastic is injected. Top 15a of
Protective materials 16 and 14 made of a resin layer are integrally formed around the plastic ring 15, the overlapped portion 11 a of the body portion 11, and the joined portion 17 formed by winding the bottom plate 12 and the body portion 11, so that the contents are formed. There is known a paper container 10 with a plastic ring having improved storage stability.

In such a case, the gas barrier properties near the plastic ring 15 and the top 15a of the paper cup and the vicinity of the joint are low, and the preservability of the contents may be reduced. As shown in FIG. 4, in a container body in which a plastic ring 15 is provided in a normal paper cup having a top curl 15b on the top, a top curl 1 is provided.
There has been a problem that the thickness of the flange portion f including the portion 5b becomes thick, and the mechanical aptitude at the time of filling the contents decreases. Therefore, the present invention has been made to solve the above-mentioned problem, and a pre-curl is applied to the top of a paper cup, this paper cup is placed in an injection molding die, molten plastic is injected, and a paper cup member is provided on the back side of the flange portion. The object of the present invention is to provide a composite cup which has a strong and excellent moldability.

A composite cup having a paper cup member up to the back side of the flange portion f of the plastic ring 15 is obtained by inserting and holding a paper cup having a pre-curl p at the top end of the plastic ring 15 in an injection mold and injecting molten plastic. It is. That is, as shown in FIG. 1, a container such as a paper cup having a pre-curl p applied to the top is placed in an injection mold, and molten plastic is injected into the mold and a plastic is placed around the top pre-curl p. The ring 15, the protective material 16 of the overlapping portion 11 a of the body 11, the protective material 14 of the joint 17 between the body 11 and the bottom plate 12, and the stopper for stacking the container at the lower end of the protective material 16. A certain projection piece k is simultaneously injection-molded.

られた。As described above, the present invention has the following effects. In other words, by using a paper cup with a pre-curl applied to the top of the body, a plastic ring is molded on this pre-curl.Thus, the thickness of the flange can be reduced, and the flange can be molded widely. In addition, since there is no portion formed only of the molten plastic in the body of the container, it is strong even if it is thin, and when filling the contents, suitability for a filling machine, gas barrier properties such as oxygen, and light shielding properties are improved. In addition, this composite cup has remarkably improved strength against impacts received from the lateral direction. In addition, when the plastic ring formed on the top is injection-molded with a transparent resin, a composite cup excellent in design such that a pattern or the like applied to the top surface of the pre-curl of the paper cup can be seen from the top of the cup. was gotten.
