The female screw 2c is screwed around a vertical cap axis Y0-Y0. Reference numeral 22 denotes a storage unit that stores the nozzle 3. The storage part 22 is formed in a cylindrical shape with a bottom, and the bottom part is located on the inner side 2 on the cap axis Y0-Y0.
a.

Reference numeral 22a denotes an insertion hole for the straw 11 provided on the bottom surface of the storage portion 22, and is provided on the inner surface 2a of the bottle cap 1.
To the outer side 2b. 22b is a claw portion bent inside the inner wall surface at the upper end of the storage portion 22, and 22c is a folded portion. The folded portion 22c has a folded shape, and has a non-slip function for suppressing the movement of the straw 11 inserted into the insertion hole 22a. Reference numeral 28 denotes a hinge portion provided at one end of the main body 2 to rotatably support the lid 4, and 29 denotes a locking portion formed at the other end of the cap shaft Y0-Y0.

On the other hand, the nozzle 3 has a large-diameter base 31 and a tapered suction opening 32 extending from the base 31 in a water-discharge cylindrical shape.
And Reference numeral 35 denotes a ridge provided on the outer periphery of the upper end of the base 31 of the nozzle 3 to prevent the nozzle 3 from coming off. Reference numeral 36 denotes a cylindrical groove formed at the end. The inner cylinder surrounded by the cylindrical groove 36 forms a connection portion with the straw 11. The inner cylinder surrounded by the cylindrical groove 36 formed in the base 31 has a straw 1
The upper end of 1 is firmly fitted so that it can be replaced, and the middle is inserted through the insertion hole 22a. For this reason, the insertion hole 22a
There is a slight difference in difficulty between the insertion and the withdrawal of the straw 11 inserted through the drawer, and a slight resistance is applied when the straw 11 is withdrawn.

In particular, the straw 11 is made of a silicon tube having a somewhat strong spring restoring force. Thus, the nozzle 3 housed in the housing part 22 of the main body 2
The cap axis Y is set so that the base 31 is within the cylinder of the storage section 22.
It can reciprocate along 0-Y0. 41 is lid 4
Is a hinge shaft that rotatably connects the hinge part to the hinge part 28 of the main body 2, and 42 is a locking piece on the other end side. The lid 4 is a hinge shaft 41
Is rotated by more than 180 degrees around the fulcrum to open the upper space of the main body 2, the locking pieces 42 are locked by the locking portions 29, and the space above the main body 2 is surrounded.

Next, the operation of the first embodiment will be described mainly with reference to FIG. FIG. 2 illustrates a case where the bottle cap 1 of the present invention is applied to a PET bottle. After removing the special cap put on the spout of the plastic bottle 12, the straw 1 connected to the base 31 of the nozzle 3 is removed.
Insert 1 into the spout. The female screw 2c of the bottle cap 1 in the closed state as shown in FIG. 1 is screwed into the male screw of the spout, and the packing 2e interposed on the contact surface with the spout is fastened and mounted. As a result, although not shown,
The lower end of the straw 11 inserted into the plastic bottle 12 is submerged in the internal liquid 13 with a margin.

When the inner liquid 13 is to be drunk, the locking between the locking piece 42 and the locking portion 29 is released, and the lid 4 is rotated clockwise about the hinge shaft 41 to open the upper part of the main body 2. . When the lid 4 is released, the restoring force of the straw 11 acts, and the base 31 is pushed up to the upper limit position of the straw 11 or the position where the ridge 35 comes into contact with the claw 22b, and the mouthpiece 32 projects. If the air in the protruding suction port 32 is sucked, the connected flow path becomes negative pressure, and the internal liquid 13 can be drunk. As shown in FIG. 2, since the protruding mouthpiece 32 is held in the vertical direction, there is no problem in sucking and drinking the internal liquid 13.

When the lid 4 is closed after drinking, the tip of the mouthpiece 32 is pressed against the inner wall of the lid 4, and the nozzle 3 is pushed down into the storage section 22. At this time, the straw 11 connected to the nozzle 3 is compressed because its movement is suppressed by the folded portion 22c provided on the inner peripheral surface of the insertion hole 22a. At this time, the compressed straw 11 is not pushed out to the outside by the insertion hole 22a, but is bent laterally as shown in FIG. Is automatically closed and blocked.

As shown in FIG. 1, the straw 11 is
Since the flow path is closed by being bent in a "one-letter shape" on the bottom surface of the PET bottle 1
Even if 2 falls down, the inner liquid 13 does not flow out.
According to the first embodiment, a spring for projecting the nozzle 3 is unnecessary, and a troublesome assembling operation can be omitted, and the number of parts and the number of assembling steps can be reduced, thereby contributing to cost reduction.

Further, since the nozzle 3 is covered with the lid 4 in the housed state, there is no contact with clothes or the like and no adhesion of dust, so that a sanitary state can be maintained. When dust or the like adheres and becomes dirty, the nozzle 3 can be pulled out from the storage portion 22 of the main body 2 and the easily dirty nozzle 3 can be easily and thoroughly washed in a separated state. Similarly, if necessary, the straw 11 and the packing 2e can be disassembled from the main body 2 and cleaned. Thus, by disassembling and cleaning, the bottle cap 1
Can be kept clean and can be used for a new plastic bottle 12.

Embodiment 2 FIG. 3 is a sectional view of a main part showing the configuration of the second embodiment. In FIG.
A recess formed on the inner surface of the cap shaft Y0-Y0,
44 is a plate packing. A material such as silicon having elasticity is used for the plate packing 44, and is detachably press-fitted into a recess 43 having a slightly smaller diameter. The press-fitted plate packing 44 is fitted on the same surface as the inner surface of the lid 4 or slightly lowered from the surface. Then, as shown in FIG.
Is pressed against the plate packing 44 so that the opening of the flow path is closed and the leakage of the internal liquid 13 is prevented. In this case, the "one-shaped" bent portion of the straw 11 does not necessarily have to block the flow path.

In both of the above embodiments, the present invention has been described by exemplifying a case in which the present invention is applied to a spout provided with a male screw of a plastic bottle filled with natural water or the like, but an alternative structure of a female screw is used. For example, the present invention can be applied to other bottles such as a water bottle and a baby bottle. Further, the shapes of the main body and the nozzle are not necessarily limited to the embodiment as long as they perform the same function.
