BACKGROUND OF THE INVENTION
The present invention relates to a water bottle with a mouthpiece, and particularly to a coil spring for biasing a mouthpiece member. In addition, the water bottle with a drinking mouth may be called a water bottle with a straw.
[0002]
[Prior art]
In general, a water bottle with a drinking mouth provided with a drinking mouth with a cap with a lid is widely used. This water bottle is generally provided with a penetrating portion in a stopper fitted to the opening of the water bottle main body, and a spout member is inserted through the penetrating portion with a certain stroke so as to move up and down, and is inserted into a lower end portion of the spout member. A tube is connected, and the lower end of the tube is suspended inside the water bottle body. The upper end portion of the coil spring fitted to the outer periphery of the mouthpiece member is supported by the spring receiving portion of the mouthpiece member, and the lower end portion is supported by the penetrating portion so that the mouthpiece member protrudes in the protruding direction. An urging force is applied, and the drinking mouth member is immersed against the urging force by a lid attached to the stopper. When the user opens the lid, the mouthpiece member rises by a certain stroke due to the urging force of the coil spring, so the user should attach the mouth directly to the mouthpiece and suck the beverage inside the water bottle body. (For example, refer to Patent Document 1 and Patent Document 2).
[0003]
The lower end portion of the coil spring is supported directly at the penetrating portion of the plug as in Patent Document 1 and supported at the penetrating portion of the plug via an O-ring that also serves as a seal as in Patent Document 2. There is something.

[Problems to be solved by the invention]
In the water bottle as described above, the portion of the stopper is liable to become dirty due to attachment of tea astringency etc., and therefore it is recommended that the user frequently disassemble and clean. In the disassembly and cleaning, as in Patent Document 1, in the case where the lower end portion of the coil spring is directly supported by the penetrating portion of the plug, when the tap member is pulled out from the plug, the coil spring is pulled out of the tap member. There is a risk that it may be lost. In addition, as disclosed in Patent Document 2, the lower end of the coil spring supported by the O-ring has an advantage that it is difficult to pull out, but when the coil spring is extracted and cleaned, it is necessary to remove the O-ring, It is complicated because it is necessary to put it back to its original state after completion, and the O-ring may be lost at that time.
[0006]
Therefore, the present invention does not easily disengage the coil spring when disassembling, and can be easily disassembled and cleaned by attaching the coil spring to the drinking mouth member without using other members. It is another object of the present invention to provide a drinking water bottle with no risk of losing parts.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a penetrating portion in a stopper fitted in an opening of a water bottle body, and moves a drinking mouth member communicating with the inside of the water bottle through the penetrating portion with a certain stroke. The upper end portion of the coil spring fitted through the outer periphery of the mouthpiece member is supported by the spring receiving portion of the mouthpiece member, and the lower end portion is supported by the penetrating portion, thereby the mouthpiece member. In the water bottle with a mouthpiece, which is provided with a biasing force in a protruding direction and pushes down the mouthpiece member against the biasing force by a lid attached to the stopper, the coil is attached to the spring receiving portion of the mouthpiece member. The structure which provided the engaging part of the upper end part of the spring was employ | adopted.
[0008]
According to said structure, since the upper end part of a coil spring is engaged with the drinking mouth member, even if this drinking mouth member is extracted from a stopper, a coil spring does not remove easily. Further, when it is necessary to remove it, it is only necessary to disengage it, and other parts such as the O-ring are unnecessary, so there is no risk of losing the parts.
[0009]
As the structure of the engagement portion, a configuration in which an engagement protrusion larger than the natural inner diameter of the coil spring is provided on the outer peripheral surface of the spring receiving portion can be adopted. According to this configuration, the upper end of the coil spring is engaged with the engaging protrusion in a state where the diameter of the coil spring is elastically expanded. Can be removed.
[0010]
In addition, the structure which provided the engaging groove of the diameter smaller than the internal diameter of the natural state of the said coil spring between the said engaging protrusion and the said spring receiving part can be taken. In this case, the upper end portion of the coil spring passes over the engaging protrusion and fits into the engaging groove, so that it is more difficult to come off, but it can be easily removed by pulling with a force that is sufficient to release from the engaging groove. .
