Rotate. At this time, the lid portion 42 is located above the lid base 10 UP. Further, at this time, the lid portion 42 is opened, and at least a portion of the first opening 11 and the second opening 13 are exposed.

When the user pushes the pushing part 41 further into the lower side LO, the opening/closing part 40 rotates to a position P4 where the plate surface direction of the opening/closing part 40 substantially matches the vertical direction V, as shown in FIG. 3(a). . At this time, the entire first opening 11 and second opening 13 are exposed.

Next, the opening/closing part 40 is further rotated to bring the upper UP surface of the lid base 10 and the upper UP surface of the lid part 42 at the first position P1 closer to each other. At this time, the lower LO surface of the lid base 10 and the lower LO surface of the push-in part 41 at the first position P1 also approach. The position of the opening/closing part 40 at this time is defined as position P5, as shown in FIG.

Next, the opening/closing part 40 is further rotated, and as shown in FIG. 3(b), the opening/closing part 40 is rotated to the second position P2. At this time, the upper UP surface of the lid base 10 and the upper UP surface of the lid part 42 at the first position P1 are in contact with each other. Further, the lower LO surface of the lid base 10 of the peripheral edge 11a of the first opening 11 is in contact with the lower LO surface of the push-in portion 41 at the first position P1.

After rotating the opening/closing part 40 to the second position P2, as shown in FIG. 3(b), the opening/closing part 40 is inserted into the holding notch 12 from the front side FR to the rear side RR and held.

FIG. 4 is a front view of the lid 100 with the opening/closing part 40 located at the second position P2. Before the opening/closing part 40 is inserted into the holding notch 12, the holding notch 12 is divided into two by the holding connecting part 12a, as shown in FIG. When inserting the opening/closing part 40 into the holding notch 12, the holding connecting part 12a is cut to release the division of the holding notch 12, and the holding notch 12 becomes large enough to insert the opening/closing part 40.

According to the lid body 100 of this embodiment, the opening/closing part 40 can be rotated by pushing the push-in part 41 into the lower side LO, and the lid part 42 can be opened to expose the first opening part 11 and the second opening part 13. Can be done. Moreover, when the opening/closing part 40 is located at the second position P2, the opening/closing part 40 can be held at the second position P2 by inserting the opening/closing part 40 into the holding notch 12. Before inserting the opening/closing part 40 into the holding notch 12, the holding notch 12 is divided into two by the holding connecting part 12a, thereby suppressing the formation of unnecessary holes in the lid body 100. Further, when the opening/closing part 40 is located at the first position P1, the pushing part 41 and the lid base 10 are connected by the pushing connection part 41a to prevent the opening/closing part 40 from rotating relative to the lid base 10, Only when necessary, the push-in connection part 41a can be cut and the opening/closing part 40 can be rotated to expose the first opening 11 and the second opening 13.

For example, in the lid body 100 that covers a cup filled with a beverage, the first opening 11 and the second opening 13 are covered by the opening/closing part 40, and the push-in connection part 41a connects the push-in part 41 and the lid base 10. Since the opening/closing part 40 does not rotate, the beverage is less likely to leak out of the cup. When the user drinks a beverage, the user pushes the push-in part 41 into the lower side LO and rotates the opening/closing part 40 to expose the first opening 11 and the second opening 13. The user can drink the beverage in the cup through the exposed first opening 11. Furthermore, by inserting and holding the opening/closing part 40 into the holding notch 12, the user can leave the first opening 11 exposed without pressing the opening/closing part 40 with his or her hand, and can easily drink the beverage. be able to. Furthermore, when the user drinks a beverage through the first opening 11, the second opening 13 is located near the user's nose, so the user cannot feel the aroma of the beverage through the second opening 13. can. For example, if the beverage filled in the cup covered by the lid 100 is coffee, the user can drink the coffee through the first opening 11 and also feel the aroma of the coffee through the second opening 13.

In addition, by pulling out the opening/closing part 40 from the holding notch 12 and making the opening/closing part 40 rotatable, the first opening 11 and the second opening 13 can be covered and closed by the opening/closing part 40 again. Since the lid part 42 covering the first opening part 11 rotates on the upper side UP of the lid base part 10, it does not come into direct contact with the beverage and is excellent in hygiene.

FIG. 13(b) is a cross-sectional view of the lid 100J and the cup 1 taken along the cross-sectional line AA in FIG. 13(a). Here, the central axis of the bottomed, substantially cylindrical cup 1 in the vertical direction V is the "central axis AX," the radial direction of the cup 1 is the "radial direction R," and the direction toward the central axis AX is the "radial direction R." The side opposite to the inside IN is defined as the "outside OU" in the radial direction R.

The outer fitting side wall portion 50a is formed of a single thin plate of paper or plastic, and includes a side wall portion 51, an outer fitting connection portion 52, and an outer fitting portion 53. The side wall portion 51 has a substantially cylindrical shape whose diameter is expanded toward the lower side LO. The outer peripheral edge of the lid base 10 and the peripheral edge of the upper side UP of the side wall part 51 are connected. The outer fitting connection portion 52 has a substantially annular shape with a plate surface direction substantially parallel to the radial direction R. The peripheral edge of the lower side LO of the side wall portion 51 and the inner peripheral edge of the outer fitting connection portion 52 are connected. The outer fitting portion 53 has a substantially cylindrical shape whose diameter is expanded toward the lower side LO. The outer periphery of the outer fitting connection part 52 and the periphery of the upper side UP of the outer fitting part 53 are connected.

The lid 100J may be formed from a single sheet of paper or a thin plate of plastic, or may be formed by connecting two or more thin sheets. Further, the lid body 100J may be formed by bending a thin plate by processing such as pressing, or may be formed by injection molding using resin.

Since the lid body 100J includes the outer fitting side wall portion 50a, by covering the cup 1 with the lid body 100J from the upper side UP and the outer side OU, the outer fitting connection portion 52 and the outer fitting portion 53 are fitted to the cup 1. Thus, the lid 100J can be connected to the cup 1.

(Modification 10)
In the above embodiment, the lid 100 includes the lid base 10, the first uncut portion 20, the second uncut portion 30, and the opening/closing portion 40, but the aspect of the lid is not limited to this.

FIG. 14(b) is a cross-sectional view of the lid 100K and the cup 1 taken along the cross-sectional line BB in FIG. 14(a). The inner fitting side wall portion 50b is formed of a single thin plate of paper or plastic, and has a substantially cylindrical shape whose diameter is reduced toward the lower side LO. The outer peripheral edge of the lid base 10 and the inner peripheral surface of the inner fitting side wall part 50b are connected.

The lid body 100K may be formed from a single sheet of paper or a thin plate of plastic, or may be formed by connecting two or more thin sheets. Further, the lid body 100K may be formed by bending a thin plate by processing such as pressing, or may be formed by injection molding using resin. For example, when the outer peripheral edge of the lid base 10 and the inner peripheral surface of the lower LO end of the inner fitting side wall 50b are connected, the lid 100K can be formed from a single thin plate.

When the lid 100K is inserted into the inner side IN of the cup 1 from the upper side UP in the cup 1 having an inner circumferential diameter that substantially matches the diameter of the outer circumferential surface of the inner fitting side wall 50b, the inner fitting side wall 50b and the cup 1 is reduced in diameter to the lower side LO, the lid 100K is fixed near the upper end UP of the cup 1, and the lid 100K can be connected to the cup 1.

The lid 100K may have a shape that allows the user to take the lid 100K out of the cup 1 by pinching it with his/her hand. For example, when the lid 100K is connected to the cup 1, a part of the inner fitting side wall 50b is connected so that a part of the inner fitting side wall 50b protrudes beyond the upper UP end of the cup 1. It may be extended to the upper side UP. The user can easily disconnect the lid 100K and the cup 1 by pinching the inner fitting side wall portion 50b that protrudes above the upper UP end of the cup 1 with his or her hands.

(Modification 11)
In the above embodiment, the lid 100 exposes the first opening 11 when the lid 42 opens upward, but the aspect of the lid is not limited to this.
