A projecting piece 26 projecting toward the center side is connected to the frame 20 so as to be continuous with the joint portion 23.
A spout 27 is formed on the projecting piece 26. A portion of the projecting piece 26 on the tip side of the spout 27 is a recess 28.

On the other hand, as shown in FIGS. 1 and 4, the cover plate 21 is made of a laminated paperboard having a polyethylene film bonded to the inner surface thereof, and a U-shaped notch is formed in the substantial center thereof. 31 is formed.
Then, the cutting guide portion 32 is formed so as to extend from both ends of the cut 31 to the outer peripheral side portion of the lid plate 21. The area surrounded by the U-shaped cut 31 is the pull tab 33.

In the above-mentioned structure, the lid plate 2 made of paper is used.
Reference numeral 1 denotes an upper surface of the frame 20, which is bonded or glued or bonded to a portion inside the ring-shaped fitting portion 22 by a joint portion 23. At this time, the lid plate 21 is similarly joined to the peripheral portion of the projecting piece 26. It should be noted here that the inner surface of the pull tab 33 is on the tip side of the projecting piece 26 and not the recess 28.
It is that the part of is not glued.

After the lid plate 21 is joined to the frame 20 in this manner, the lid plate 21 is fitted into the upper opening of the container 10 filled with the contents, for example, the beverage as shown in FIG. At this time, the ring-shaped fitting portion 22 of the frame 20 is fitted to the flange 11 of the container 10. Then, if necessary, the ring-shaped fitting portion 22 is heat-sealed with the flange 11. As a result, the upper opening of the container 10 is closed by the lid. In such a state, the beverage filled in the container is provided for physical distribution.

When drinking a beverage filled in such a container, as shown in FIG. 10, the portion of the pull tab 33 surrounded by the U-shaped cut 31 of the lid plate 21 is pushed with a finger. The portion of the pull tab 33 is not glued or adhered to the surface of the projecting piece 26 of the frame 20, and the recess 28 is formed on the lower side thereof. It will be lifted by its existence. Therefore, by grasping the tip end of the lifted pull tab 33 with a finger and pulling it upward, the cutting guide portion 32 continuous with the pull tab 33 is broken as shown in FIG. 7.

Thus, pulling the pull tab 33, the lid plate 2
When a part of 1 is cut and removed by the cutting guide portion 32, the spout 2 formed on the projecting piece 26 of the frame 20
7 will be exposed and opened. Therefore, it becomes possible to pour and drink the beverage in the container through the opening 27.

According to such a lid structure of the container, it is composed of the frame 20 made of synthetic resin and the lid plate 21 made of paperboard, which is different from the conventional aluminum foil laminate sheet, molding lid, drop lid and the like. It is possible to give a high-class feeling to the product, and it becomes a simple container with a high-class image. Further, when the pull tab 33 is pulled, only the spout 27 of the projecting piece 26 is opened, and the entire upper opening of the container 10 is not opened.

When the pull tab 33 is pulled to break a part of the lid plate 21, the exposed surface of the protruding piece 26 at the peripheral portion of the spout 27 has been covered by the lid plate 21 until then. The periphery of the spout 27 is less likely to be soiled,
For this reason, it becomes possible to hygienically drink the beverage inside.

The main body of such a lid is the lid plate 21.
The frame 20 is made of synthetic resin, and only the outer peripheral side is formed. Therefore, the amount of synthetic resin used is reduced. This makes it possible to provide a lid that can be easily incinerated and discarded.

Next, a second embodiment will be described with reference to FIGS. In this embodiment, an outer peripheral wall 37 is formed on the outer peripheral portion of the frame 20 in place of the ring-shaped fitting portion 22. The outer peripheral wall 37 has a relatively low height, and has a size slightly larger than the thickness of the flange 11 of the container 10 as shown in FIG. The outer peripheral surface of the flange 11 of the container 10 is fitted to the inner peripheral surface of the outer peripheral wall 37.

The outer peripheral wall 37 on the outer peripheral side of the frame 20 projects upward to form ribs 38. That is, the frame 20 has ribs 3 on the outer peripheral side of the joint portion 23.
8 are formed. The lid plate 21 is joined to the upper surface of the joining portion 23 which is the inner peripheral side of the rib 38. Therefore, according to such a frame 20, the diameter of the cover plate 21 is slightly larger than that of the first embodiment. The other structure is the same as that of the first embodiment.

Therefore, the lid of the container having such a structure is also
By using the concave portion 28 of the projecting piece 26 to press the portion of the pull tab 33 with a finger to raise the tip portion, and pulling the tip portion of the pull tab 33 with a finger to pick it, the lid plate 21 as shown in FIGS. 11 and 12. The region surrounded by the cutting guide portion 32 is broken. Therefore, the spout 27 of the projecting piece 26 of the frame 20 is exposed.
It is possible to pour out the beverage in the container through.

According to this structure, since the lid plate 21 extends to the inner circumference of the rib 38 at the outer peripheral side of the lid,
It becomes possible to cover a wider area with the cover plate 21. Therefore, when the opening 27 is opened to expose the spout 27 as shown in FIG. 12, a portion of a wider region which has been covered by the lid plate 21 until now is exposed. As a result, it becomes possible to sanitarily drink the beverage inside.

Next, a third embodiment will be described with reference to FIGS. In this embodiment, the spout 27 is formed on the projecting piece 26 of the frame 20, but no recess is provided on the tip side thereof. A step portion 42 is formed on the upper surface of the ring-shaped fitting portion 22 of the frame 20 so as to correspond to the spout 27, and the step portion 42 is slightly lower than the other portions.

Further, in this embodiment, the lid plate 21 is provided with a pull tab 33 so as to project to the outer peripheral side, and
The cutting guide portion 32 is formed so as to extend in an arc shape from the root portion thereof. Such a lid plate 21 is combined with the frame 20 as shown in FIG. 16, and the lid plate 21 closes the spout 27 of the projecting piece 26 of the frame 20 and the pull tab 33 is received in the step portion 42. It is adapted to be combined with the frame 20 in the state.

When a beverage in the container 10 whose upper opening is closed by such a lid is to be drunk, as shown in FIG. 17, the lid protruding toward the outer peripheral side through the step portion 42 of the ring-shaped fitting portion 22 of the frame 20. The pull tab 33 of the plate 21 may be pulled. When the pull tab 33 is picked up with a finger and pulled, the cover plate 21 is broken at the cutting guide portion 32 as shown in FIG.
Therefore, the spout 27 formed on the projecting piece 26 of the frame 20 is exposed, and it becomes possible to drink the beverage therein through the spout 27.

With such a structure as well, it is possible to provide a lid which can give a high-class feeling and can be partially opened. Further, it is possible to previously cover the part that comes into contact with the lips when drinking with the pull tab 33, so that the part that comes into contact with the lips is not contaminated and the structure becomes hygienic.

Next, a fourth embodiment will be described with reference to FIGS. In this embodiment, the pull tab 45 is connected to the frame 20 side instead of the cover plate 21. Moreover, since the spout is not formed from the beginning, the protrusion 26
The cutting guide portion 49 is formed on the surface, and the spout is formed only when this portion is broken.

As shown in FIGS. 19 to 21, the frame 20 is provided with a substantially rectangular projecting piece 26. A substantially central portion of the projecting piece 26 is composed of a concave portion 28, and a cutting guide portion 49 is formed so as to surround the concave portion 28. Further, a cap 45 which also serves as a pull tab is continuously provided via a connecting portion 48 so as to be connected to the inside of the region cut by the cutting guide portion 49. A projecting portion 46 projecting downward is formed substantially in the center of the cap 45, and the projecting portion 46 is substantially aligned with the recess 28 of the projecting piece 26 as shown in FIG. A projecting piece 47 is formed at the end of the cap 45, and the projecting piece 47 is aligned with the step 42.

The lid plate 21 joined to the frame 20 having such a structure is provided with a U-shaped notch 53, and the notch 53 is located outside the cutting guide portion 49 of the projecting piece 26. The lid plate 21 is glued or bonded to the joint portion 23 of the frame 20 and the protruding piece 26 to be joined.

Such a lid is attached as shown in FIG. 22 so as to close the upper opening of the simple container 10 filled with the beverage. The flange 11 and the frame 20 of the container 10
The fitting is achieved by the fitting structure of the outer peripheral wall 37 formed on the outer peripheral side of the frame 20 and the flange 11.

When drinking the beverage in the container 10 thus combined, as shown in FIG. 23, the pull tab 45 which also serves as a cap is rotated upward by the projecting piece 47. Since the connecting portion 48 has a hinge structure, the pull tab 45 can be easily rotated. After that, by pulling the pull tab 45 and pulling it upward, the portion of the cutting guide portion 49 of the projecting piece 26 is broken as shown in FIG. Therefore, the outer peripheral side portion of the concave portion 28 of the projecting piece 26 is broken and removed, and the spout is formed. Therefore, it becomes possible to pour out the beverage therein through such a spout.

In such a structure, the opening portion is not the lid plate 21 made of paperboard but the frame 2 made of an injection molded body.
Since it is performed in the portion of the protruding piece 26 of 0, the opening structure has a higher quality. Moreover, since the portion to be opened is completely covered by the cap 45 which also serves as the pull tab, the portion around the spout is less likely to be contaminated, which results in a more hygienic opening structure.

Next, a fifth embodiment will be described with reference to FIGS. In the container of this embodiment, a cutting guide portion 49 is formed on the projecting piece 26 of the frame 20 so as to surround the recess 28, and the connecting portion 48 is projected so as to be connected to the region cut by the cutting guiding portion. It is provided at the root side of 26 and on the outer peripheral side, and this connecting portion 48 is connected to the cap 45. A protrusion 47 is formed on the outer peripheral portion of the cap 45, and the protrusion 47 forms the rib 3 at the upper end of the outer peripheral wall of the frame 20 on the outer peripheral side.
It is adapted to be received in the stepped portion 42 of 8.

On the other hand, the lid plate 21 is provided with a notch 53 so as to be joined to the projecting piece 26 outside the cutting guide portion 49 of the projecting piece 26.

Container 10 closed by such a lid
When drinking the beverage therein, as shown in FIG. 29, the pull tab 45 which also serves as a cap is rotated around the connecting portion 48 and raised. After that, when the pull tab 45 is picked up and pulled upward, the projecting piece 2 connected through the connecting portion 48.
An area inside the cutting guide portion 49 of 6 is broken and removed by the cutting guide portion 49, thereby forming a spout. Therefore, it becomes possible to drink the beverage therein through such a spout.

Even with such a structure, it is possible to provide a high-class lid capable of partially opening. Moreover, since the lid formed by cutting the cutting guide portion 49 is closed from above by the cap 45, the surrounding area is not polluted and especially the portion where the lips come into contact is kept clean. The hygienic opening structure becomes possible.
