ABSTRACT:
BACKGROUND OF THE PRESENT INVENTION
1. Field of the Present Invention
The present invention relates to a drinking straw, and more particularly to a drinking straw that can selectively provide a vibrating convoluted part when sucking liquid through the straw.
2. Description of Related Arts
Conventional drinking straws have been manufactured of plain coated paper and plastic material and it is know to provide drinking straws of transparent plastic materials with convoluted parts between the upper and lower ends of the straw. These convoluted parts do not enhance the drinking capability of the straw but are present as decorative features. And, a dynamic function by the vibration in itself is more interesting and attractive in its usage and appearance, so as to increase the sales potential of the straws.
SUMMARY OF THE PRESENT INVENTION
It is an object of the present invention to provide a new form of such decorative and dynamic drinking straw. In accordance with the invention, a drinking straw is provided, which comprises a straw, a fixed collar, and a moveable collar. The straw has an upper part having an open upper end for reception in the mouth of a user, a lower part having an open lower end for immersion in a liquid to be sucked through the straw by the user, a convoluted part provided between the upper and lower parts a passageway extending through the fix collar and a side wall of the lower part in cooperation with the embodiment of the moveable collar, and means for selectively closing and opening the passageway, whereby when the passageway is in an opening position inside the moveable collar, air is sucked into the straw through the passageway when liquid is sucked through the straw by the user, thereby to create vibrations in the convoluted part of the straw.
