Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a so-called pop-up water bottle in which a straw protrudes during drinking.

(Prior art) This type of water bottle is published in Utility Model No. 58-8098 and No. 58-8098.
As seen in No. 11722, etc., it generally has a built-in straw, and the straw performs the pop-up using spring force. On the other hand, due to structural needs, there were some models that had a straw separate from the mouthpiece and the inside of the water bottle, but in order to prevent the straw from accidentally coming off, the straw did not come off easily and commercially available straws could not be used. It's getting old. However, when children use the straw, they may chew on it, making the straw unusable even if the main body itself is intact. Also, straws inside water bottles can become unsanitary if not taken care of.

(Technical Problem) Therefore, the present invention solves the above problems by making at least the mouthpiece side of the straw removable and replaceable, and by making the straw pop-up possible with an elastic member. To provide a water bottle with a straw that has improved operability by having a structure that allows for smoother operation.

(Technical Means) In order to achieve the above-mentioned object, the present invention provides an elastic member 1 for extruding a straw that has a hollow interior and exerts an elastic restoring force in the direction of extension when compressed when not in use. The straws 3 and 4 are installed in the guide 2 of the telescopic member 1 in a removable and replaceable manner in the upper and lower mounting ports 5 and 12 at both ends of the telescopic member 1, and when the upper straw 3 is installed, the upper mounting port 5 of the telescopic member 1 is removed. while fixing the spring receiver 18 to the guide 2, attaching the fixing member 15 of the telescopic member to the lower end opening of the guide 2;
A spring 6 that assists the restoring force of the elastic member 1 is provided between the spring receiver 18 and the fixed member 15.

(Function of the invention) In the present invention, the upper straw 3 is connected to the attachment port 5 provided at the upper part of the telescopic member 1 for extruding straws, so if the upper straw 3 is damaged or the whole is dirty, it can be attached. It can be separated from the openings 5 and 12 and replaced with another straw such as a commercially available straw. Since the elastic member 1 provided with the straws 3 and 4 is configured to exert an elastic restoring force when compressed when not in use, the elasticity can be used to push out the straw, and the elastic member 1 also has an elastic restoring force. Since the spring 6 that assists the force is provided, even if the restoring force of the elastic member 1 changes due to low temperature or changes over time, there is little change in the protruding action of the straw.

(Example) The water bottle of the example is made of synthetic resin and consists of a cylindrical container member 7 and a substantially hemispherical lid member 8 attached to its opening, and both members 7 and 8 are formed at the respective opening ends. They are assembled by a male screw 7a and a female screw 8a. Reference numeral 9 denotes an attachment portion of the packing 10 formed deep inside the lid member 8, and 11 denotes a hanging portion formed within the lid, which fits into the opening of the container member 7 and contributes to improved sealing performance.

The extensible member 1 for extruding a straw in the embodiment is made of synthetic resin and has an elastic cylindrical bellows shape, and has attachment ports 5 and 1 protruding from both upper and lower ends.
2 are integrally molded. For this reason, the attachment ports 5 and 12 are made into tapered tubular shapes that become smaller in diameter toward the tips, making it easier to attach the straws 3 and 4, and also making it possible to use commercially available straws with slightly different diameters by absorbing the difference in diameter. ing. The specific connection structure for preventing the attachment ports 5, 12 and the upper and lower straws 3, 4 from being pulled out can be arbitrarily designed. 5a and 12a indicate the neck. The guide 2 that supports the telescopic member 1 has a cylindrical shape with a length that can accommodate the telescopic member 1, has a small diameter portion 13 for inserting a straw at the tip, and has a screw 14 on the outer periphery of the proximal end. A member 15 for fixing the lower end of the telescopic member 1 is screwed onto the screw 14 with a screw 16, and the neck portion 12a is fitted into a hole 17 provided in the lower end fixing member 15, so that the telescopic member 1 is attached. 18 is a spring receiver, 19 is its hole, and the spring receiver 18 is the other neck portion 5a of the elastic member 1.
Since the spring 6 is fitted and attached to the lower end fixing member 15 and the spring receiver 18, the spring 6 is compressed between the lower end fixing member 15 and the spring receiver 18, and assists the elastic member 1 to recover and expand. 20 is a bellows-shaped bent part formed in the middle of the lower straw 4, and the lower straw 4 is always in contact with the bottom of the container member 7.
It supports the expansion and contraction mechanism of the straw 3. Reference numeral 21 denotes an upper straw outlet opening opened above the lid member 7, and 22 denotes a small lid detachably attached to the pipe portion.
It is attached and detached by means of engagement means with the outer periphery of the tube part. The engaging means of the embodiment is of a twist type and consists of two hook-shaped protrusions 23, 23 and protrusions 24, 24 on the small lid 22 side that engage with the hook-shaped protrusions 23, 23, and the protrusions 24 are stopped by the vertical stripes 23a. 25 is a plug ring fixed to the small lid 22;
26 is a connecting ring fixed to the straw outlet 21, 27 is a chain connecting both rings 25 and 26,
Further, 28 is a protrusion for fixing the connecting ring 26.

Therefore, when the small lid 22 is removed, the upper straw 3 protrudes according to the length of the elastic member 1 in its natural state due to the release of the straw extrusion elastic member 1 and its assisting spring 6. At this time, the upper straw 3 operates smoothly due to the elastic restoring force of the elastic member 1 and the spring 6. By strengthening and lengthening the spring 6, it is possible to extend the elastic member 1 beyond its natural length.
The reverse is also possible.

(Effects of the invention) The present invention is constructed as described above, and even if the upper straw 3 protruding from the water bottle is damaged or the upper and lower straws 3, 4 become dirty, they can be replaced. The elastic member has the flexibility of being able to replace one or both of the upper straws 3 as needed, and is economical and particularly suitable for children as it can use a commercially available straw. 1 and a spring 6 to assist the restoring action, the straw pops up very smoothly, and the elastic member 1 with a serpentine structure may become hard at low temperatures, and the material may deteriorate if used for a long time. There is also a gender, but
The device of the present invention is equipped with a spring 6, so even if such a situation occurs, the straw can be smoothly ejected, and since the spring 6 is attached using the detachable structure of the upper straw 3, the number of parts can be reduced. Since it does not increase in number and the structure does not become complicated, it has the effect of improving operability.
