[0014]
The straw 20 is not a single one as in the prior art, but is attached to the attachment portion 30 and drooped into the cup body with a straw main portion 21 fitted into the attachment portion 30 in a rotatable state and obliquely upward. It is comprised by the straw mouth part 22 which protrudes. In the illustrated example, the upper inner straw main portion 21 is fixed by the insertion state to the lower outer side of the stepped cylindrical portion component 32 in the center of the attachment portion 30, also the straw hole portion 22 stepped cylindrical portion content of 32 fitted into, and is rotatable state by the engagement of the groove of the inner peripheral surface of the outer circumferential surface of the protruding cylindrical portion content of 32 of the straw hole portion 22.
[0015]
Here, the cap 40 can be capped when the straw port portion 22 is tilted toward the hinge 41, but cannot be capped when the straw port portion 22 is tilted to the opposite side. Further, the vent hole 23 provided at a lower end of the straw hole 22, also on top of the stepped cylindrical portion content of 32 of the attachment portion 30 is provided with vents 33, straw port portion 22 of the hinge 41 of the cap 40 Only when it is inclined in the direction, the two vent holes 23 and 33 are connected so that the inside of the straw communicates with the inside of the cup body.
[0016]
When a hot drink is contained in the cup in the sealed state shown in FIG. 2, the internal pressure increases, but when the cap 40 is removed from the attachment portion 30 in this state, the cup is attached to the vent hole 23 of the straw port portion 22. since the vent hole 33 of the cylindrical portion content of 32 parts 30 are communicated, pressure drops escaping air. Therefore, even when the lid 10 is set in a hermetically sealed state when the milk is prepared using hot water, the internal pressure can be lowered simultaneously with the operation of removing the cap 40 when drinking.
[0017]
After drinking the cap 40, when drinking the contents, the straw mouth part 22 is rotated to the opposite side of the hinge 41 as shown in FIG. This operation, communication between the vent hole 33 of the cylindrical portion worth 32 of the attachment portion ventilation hole 23 of the straw hole portion 22 is cut off, ready to halfway closed the straw 20 will be able to吸飲the contents . In addition, even after having finished drinking, since the cap 40 cannot be put on in this state, the straw port portion 22 is always rotated and returned to the original position. By this operation, the middle of the straw 20 communicates with the inside of the cup body, and prepares for the next internal pressure release.
[0018]
FIG. 4 shows an example of a second type plastic cup container according to the present invention, and is a cross-sectional view showing an enlarged main part thereof.
[0019]
This plastic cup container has a cup body, a lid body screwed into the cup body, and a straw attached through the lid body, as shown in FIG. It has a structure with a handle like that.
[0020]
In FIG. 4, reference numeral 10 denotes a lid, and an attachment portion 60 for attaching the straw 50 through a central cylindrical portion is provided above the lid 10. In the illustrated example, a ring-shaped protruding wall 11 is provided around the opening of the lid body 10, and the attachment portion 60 is fixed in a state where the peripheral edge portion 61 is fitted to the outer periphery of the protruding wall 11. Then, the cap 70 is fitted to the peripheral edge portion 61 of the mounting portion 60. The cap 70 covers the tip of the straw 50 protruding from the lid 10 in a sealed state, and is integrally attached to the lower end of the side portion of the peripheral portion 61 of the attachment portion 60 via a soft hinge 71.
[0021]
The sealing cap 70 is preferably transparent or translucent so that the straw 50 in the inside can be seen. The cap 70 can be attached through the soft resin hinge 71 by a known two-color molding method.
[0022]
The straw 50 is not a single one as in the prior art, but is fitted and fixed to a straw mouth portion 51 that is fitted in a cylindrical portion 62 of the attachment portion 60 so as to be movable up and down with a fixed stroke, and to a lower portion of the straw mouth portion 51. It is comprised by the straw main part 52 drooping in a cup main body. In the illustrated example, the straw mouth portion 51 has a spherical protrusion 51 a at the upper portion and a stepped protrusion 51 b at the lower portion, and the spherical protrusion 51 a moves downward by contacting the upper portion of the attachment portion 60. Is restricted, and the upward movement is restricted by the stepped protrusion 51b abutting against the lower portion of the mounting portion 60 (see FIG. 5).
[0023]
A vent hole 51c is provided between the spherical protrusion 51a and the stepped protrusion 51b in the straw mouth 51, and the cup body when the straw mouth 51 is at the lower position of the stroke (see FIG. 4). communication between the cup body at the inner side of the cylindrical portion 62 communicates, also when in the upper position (see FIG. 5) is adapted to be broken within.
[0024]
In the illustrated example, the cap 70 has a shape that can be capped when the straw mouth portion 51 is at the lower position of the stroke and cannot be capped when the straw mouth portion 51 is at the upper position. Further, when capping, the hemispherical projection 70a inside the cap 70 closes the upper opening of the straw port 51. For this reason, when the cap 70 is put on, the contents are prevented from overflowing into the cap 70.
[0025]
When a hot drink is contained in the cup in the sealed state shown in FIG. 4, the internal pressure is increased, but when the cap 70 is removed from the attachment portion 60 in this state, the vent hole 51 c of the straw port portion 51 is connected to the cup. Because it communicates with the body, air escapes and internal pressure decreases. Therefore, even when the lid 10 is set in a hermetically sealed state when milk is prepared using hot hot water, the internal pressure can be lowered simultaneously with the operation of removing the cap 70 when drinking.
[0026]
After drinking the cap 70, when drinking the contents, as shown in FIG. 5, the straw mouth part 51 is lifted to make it easy to drink. By this operation, the communication between the vent hole 51c of the straw port 51 and the inside of the cup body is cut off, the middle of the straw 50 is closed, and the contents can be sucked. In addition, after drinking, since the cap 70 cannot be put on in this state, the straw mouth part 51 is always pushed down to return to the original position. By this operation, the middle of the straw 50 communicates with the inside of the cup body, so that the next internal pressure release is prepared.
[0027]
