[0010]

FIG. 2 shows an example of a first type of plastic cup container according to the present invention, and is an enlarged sectional view showing a main part thereof.

As shown in FIG. 1, this plastic cup container has a cup body, a lid screwed to the cup body, and a straw attached through the lid. 1 is also provided with a handle handle as shown in FIG.

In FIG. 2, reference numeral 10 denotes a lid, and above the lid 10, a mounting portion 30 for mounting the straw 20 is provided. In the illustrated example, a ring-shaped protruding wall 11 is provided around the opening of the lid 10, and the mounting portion 30 is fixed in a state where the peripheral portion 31 is fitted on the outer periphery of the protruding wall 11. Then, the cap 40 is fitted to the peripheral portion 31 of the mounting portion 30. The cap 40 is provided with a straw 20 protruding from the lid 10.
And is integrally attached to a lower end of a side portion of the peripheral portion 31 of the attachment portion 30 via a soft hinge 41.

The sealing cap 40 is desirably transparent or translucent so that the straw 20 inside can be seen. In addition, the cap 4 via the soft resin hinge 41 is used.
The attachment of 0 may be performed by a known two-color molding method.

The straw 20 is not a single piece as in the prior art, but is fitted to a straw main portion 21 fixed to the mounting portion 30 and hanging in the cup body so as to be rotatable with the mounting portion 30. And a straw opening 22 projecting obliquely upward. In the illustrated example, the straw main part 21 is inserted and fixed to the outside of the lower part of the stepped cylindrical part 32 at the center of the mounting part 30, and the straw mouth part 22 is fixed.
Is fitted inside the upper part of the stepped cylindrical portion 32, and is rotatable by engagement of a ridge on the outer peripheral surface of the straw opening 22 with a groove on the inner peripheral surface of the cylindrical portion 32.

Here, the cap 40 is connected to the straw opening 2.
The cap 2 can be capped when tilted toward the hinge 41, but cannot be capped when tilted to the opposite side. Further, a ventilation hole 23 is provided at the lower end of the straw opening 22, and a ventilation hole 33 is also provided above the stepped cylindrical portion 32 of the mounting portion 30.
Only when tilted toward the hinge 41 of the cap 40
The two ventilation holes 23 and 33 are connected so that the inside of the straw and the inside of the cup body communicate with each other.

When a hot drink is contained in the cup in the closed state shown in FIG. 2, the internal pressure is increased. In this state, when the cap 40 is removed from the mounting portion 30, the air hole of the straw opening 22 is formed. 23 and cylindrical part 32 of mounting part 30
Is communicated with the vent hole 33, air escapes and the internal pressure drops. Therefore, even when the lid 10 is set in a closed state, for example, when preparing milk using hot water, the internal pressure can be reduced at the same time as the operation of removing the cap 40 when drinking.

After the cap 40 is removed, when drinking the contents, as shown in FIG.
Turn to the opposite side of 1 to make it easy to drink. By this operation, the communication between the ventilation hole 23 of the straw opening 22 and the ventilation hole 33 of the cylindrical portion 32 of the mounting portion is cut off,
Will be in a closed state, and you will be able to suck and drink the contents. Further, even after drinking, the cap 40 cannot be put on in this state, so that the straw opening 22 is always rotated to return to the original position. By this operation, the middle of the straw 20 communicates with the inside of the cup main body, so that the inner pressure can be released next time.

FIG. 4 shows an example of a second type of plastic cup container according to the present invention, and is an enlarged sectional view showing a main part thereof.

As shown in FIG. 1, this plastic cup container has a cup body, a lid screwed to the cup body, and a straw attached through the lid. 1 is also provided with a handle handle as shown in FIG.

In FIG. 4, reference numeral 10 denotes a lid. Above the lid 10, a mounting portion 60 for mounting a straw 50 is provided through a central through hole. In the illustrated example, a ring-shaped protruding wall 11 is provided around the opening of the lid 10, and the mounting portion 60 is fixed in a state in which a peripheral portion 61 is fitted on the outer periphery of the protruding wall 11. And
The cap 70 is fitted to the peripheral 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.
Peripheral portion 61 of mounting portion 60 via soft hinge 71
Are integrally attached to the lower end of the side.

This sealing cap 70 is desirably transparent or translucent so that the straw 50 inside can be seen. Further, the cap 7 via the soft resin hinge 71 is provided.
The attachment of 0 may be performed by a known two-color molding method.

The straw 50 is not a single straw as in the prior art, but is inserted into a through-hole 62 of a mounting portion 60 so as to be movable up and down with a constant stroke, and is inserted into a lower portion of the straw opening 51. A straw main part 52 is fixed and hangs down in the cup body. In the illustrated example, the straw mouth 51 has a spherical projection 51a at the top and a step-like projection 51b at the bottom, and the spherical projection 51a contacts the upper part of the mounting part 60 to move downward. Is restricted, and the upward movement is restricted by the step-like projection 51b abutting on the lower portion of the mounting portion 60 (see FIG. 5).

A ventilation hole 51c is provided between the spherical projection 51a and the stepped projection 51b in the straw mouth 51.
When the straw port 51 is at the lower position of the stroke (see FIG. 4), it communicates with the inside of the cup body, and when the straw port 51 is at the upper position (see FIG. 5), Communication with the main body is cut off.

In the illustrated example, the cap 70 is shaped so that it can be capped when the straw opening 51 is at the lower position of the stroke and cannot be capped when it is at the upper position. Furthermore, when capping is performed, the hemispherical projection 70 a inside the cap 70 closes the upper opening of the straw opening 51. For this reason, when the cap 70 is covered, the contents are prevented from overflowing into the cap 70.

When a hot drink is contained in the cup in the closed state shown in FIG. 4, the internal pressure is increased. When the cap 70 is removed from the mounting portion 60 in this state, the ventilation hole of the straw opening 51 is opened. Since 51c communicates with the inside of the cup body, the air escapes and the internal pressure decreases. Therefore, even when the lid 10 is set in a closed state, for example, when preparing milk using hot water, the internal pressure can be reduced at the same time as the operation of removing the cap 70 when drinking.

When the contents are to be drunk after the cap 70 has been removed, the straw opening 51 is lifted as shown in FIG. By this operation, the communication between the ventilation hole 51c of the straw opening 51 and the inside of the cup body is cut off, and the middle of the straw 50 is closed, so that the contents can be sucked and drunk. Further, after drinking, since the cap 70 cannot be put on in this state, the straw mouth portion 51 is necessarily 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 time the internal pressure is released.

[0027]

Since the present invention is configured as described above, the following effects can be obtained.

In the plastic cup container according to the first aspect, since the vent hole is opened at the same time as the cap is removed, it is possible to prevent the hot drink from being blown out of the straw and, as a matter of course, the operation is performed once. It is sure that it can be done. When the cap is put on, it is necessary to turn the straw opening to close the ventilation hole, so that the internal pressure can be released next time. In addition, since the structure is simpler than the conventional one, cleaning is easy, and
Product cost can be reduced.

In the plastic cup container according to the second aspect, since the vent hole is opened at the same time when the cap is removed, it is possible to prevent the hot beverage from being blown out of the straw and, of course, the operation is performed once. It is sure that it can be done. In addition, since the structure is simpler than that of the related art, the cleaning is easy and the product cost can be reduced.

According to the plastic cup container according to the third aspect, the shape of the cap is such that it can be capped when the straw mouth is at the lower position of the stroke and cannot be capped when it is at the upper position. It is necessary to press down the straw opening to close the ventilation hole when putting on, so that it is possible to prepare for the next release of the internal pressure without forgetting.
