していた。2. Description of the Related Art Conventionally, cups used for ice cream or the like have a structure in which contents are put into a paper cup, the opening is covered with a film-like inner lid, and an outer lid is further provided for protection. In particular, the inner lid has effects such as prevention of drying of the contents, protection of the contents, and flattening of the surface of the contents. For example, as shown in FIG. 2, the cup provided with the inner lid includes a paper cup 2 and a lid 1 having a bent portion 6. The bent portion 6 contacts the inner surface of the paper cup 2, and is bent by the seal head 4. The part 6 was adhered to the inner surface of the paper cup 2 to form a paper cup with a lid. Here, it is necessary to have a function to improve the sealing property between the lid 1 and the inner surface of the paper cup 2 and a function to easily open the lid 1 during use. In order to obtain a structure having these two functions, a release agent (such as silicon) is applied to the inner surface of the upper portion of the paper cup 2 so that the upper portion of the bent portion 6 of the lid 1 does not adhere to the inner surface of the paper cup 2. Was easy to peel off near the end.

When the outer lid is attached to the rim, the release agent may protrude, cause a defective seal, or may not be attached.

FIG. 1 is an explanatory view of one embodiment of the present invention, and is an explanatory view showing a cross-section of a paper cup 2, a lid 1, an adhesive portion 5, and a position of a seal head 4 at the time of bonding. According to the present invention, the bent portion 6 of the lid 1 having the bent portion 6 formed around it is brought into contact with the inner surface of the opening of the paper cup 2 formed in advance, and heated and pressed by the seal head 4 to form the adhesive portion 5. It is a paper cup with a closed lid. At this time, the taper “a” of the opening of the paper cup 2 is larger than the taper “b” of the bent portion 6 at the portion above the middle portion of the portion of the lid 1 in contact with the bent portion 6. As a result, since the paper cup 2 and the bent portion 6 of the lid 1 are configured as described above, when they are bonded by the seal head 4, the bent portion 6 of the lid 1, the lid 1, and the inner surface of the paper cup 2 are bent. Since only the lower portion of the portion 6 is bonded and the upper portion is not bonded, the contact area with the paper cup 2 is reduced, and the bonding portion 5
, The releasability between the lid 1 and the paper cup 2 is improved.

A paper cup having an opening was formed by a cup forming machine using a body material made of PE material and a bottom member. A top curl portion curled outward is formed at the upper end of the paper cup. In addition, the taper of the body was formed so that the taper above the middle of the portion where the lid was bonded was larger than below the middle of the portion where the lid was bonded.

る。[0008] After that, the ice cream fluid was filled into a paper cup by a filling machine, and a lid having a concave section and a bent portion formed around it was dropped and heat-sealed with a heated heat head, and the paper cup was closed. As a result of this closing, as shown in FIG. 1, the folded portion of the paper cup 2 and the lid adheres to the inner surface of the paper cup only below the folded portion, and the upper portion of the folded portion does not adhere to the inner surface of the paper cup.

果があり、採用できる。According to the present invention, since the taper of the paper cup is provided by a mold, it can be molded with good stability, so that the adhesive area with the bent portion of the lid is stable, the sealing property is good, and the silicon coating by the conventional method is applied. No instability such as uneven coating. Further, since no silicone coating is applied, even if the outer lid is provided, there is no adverse effect on the sealing performance. Although the cup body has a truncated cone shape in the embodiment, the same effect can be obtained by adopting a cylindrical shape.
