Description

[Detailed description of the invention] Industrial application field The present invention relates to a safety vidro that increases safety in the event of breakage.

Conventional technology and problems Conventional Vidros, which have been known for a long time, are made of glass and have a bead-shaped part formed at the tip of the tube, and a membrane-like sound that bulges inward at the tip of the bead-shaped part. Hold the end of the tube in your mouth, breathe in and invert the sounding part to its outward bulging shape, then relax this breath and swell it back inward. It is designed to be reversed to its original shape and returned to its original shape, and to produce a sound when it is reversed.

The vidro's sounding part is made of a thin glass membrane, so if someone who doesn't know how to play the sound accidentally takes a strong breath, the sounding part may break and the pieces could be inhaled.

The purpose of the present invention is to prevent such dangers and to realize a safe vidro that prevents debris from being sucked into the mouth even when strongly sucked.

Means for Solving the Problems The present invention is made of glass, and has a bead-shaped part formed at the tip of the tube, and a membrane-like sounding part that bulges inward at the tip of the bead-shaped part. This safety vidro is characterized by having a small hole passage in the tube part to prevent debris from passing through when the sounding part is damaged due to strong suction by mistake.

Embodiments Hereinafter, embodiments illustrating the present invention will be described in detail.

In this safety vidro, a beaded part 2 is integrally formed at the tip of a tube part 1 made of glass, and a membrane-like sounding part 3 bulging inward is formed at the tip of this beaded part 2. When you put the end 4 in your mouth and breathe in, the sounding part 3 inverts to bulge outward as shown by the chain line in the figure, and when you relax your breath, it returns to its original state. I am learning to pronounce it. The above is the same as normal Vidro.

Furthermore, in this safety beadro, a passage member 6 made of heat-resistant plastic and having a small hole passage part 5 in the center is fitted into the contact part of the tube part 1 with the beaded part 2, and the surrounding area is changed by heat and held down. , is fixed.

Since this safety vidro has the above structure, even if the sounding part 3 is damaged due to strong suction by mistake, the fragments will not pass through the small hole passage part 5 and will not be sucked into the mouth, making it safe. .

In the example above, the small hole passage is made of heat-resistant plastic and fixed by thermally deforming the tube, but it can also be made of ordinary plastic and fixed with adhesive, or made of glass and fixed integrally with the tube. It can be formed by any method. Further, the mounting position of the small hole passage section may be arbitrary, such as at the connection part with the ball-shaped part, at the end of the pipe part, or at the middle position of the pipe part. Note that the position of the small hole passage may change the strength and reverberation of the sound, so it is desirable to select it appropriately. Experiments have shown that when the small hole passage is located at the connection part with the beaded part or at the end of the tube, the effect on sound is relatively small, especially when it is located at the connection part with the beaded part as in the example shown. This position is best because it is less noticeable in appearance.

Note that it goes without saying that the bead-shaped portion can be decorated by adding color and an uneven shape.

Effects of the invention As mentioned above, the safety vidro of this invention has a small hole passage in the tube, so even if the sounding part is damaged due to strong suction by mistake, debris will not be sucked in, making it safe. It is. In addition, it is easy to put into practical use because only a few changes are made to the normal Vidro.
