Abstract

<P>PROBLEM TO BE SOLVED: To provide a drink straw that by adding two vertical grooves facing to each other, even from end to end and having no cornered part, strength is provided to the overall straw and the tap is enlarged to achieve further usability. <P>SOLUTION: A tubular straw is provided with two grooves that have no cornered part from end to end on the opposite sides of the straw to form the cross section of the straw in a "gourd" or a "peanut" shape. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the shape of drinking straws.
[0002]
[Prior art]
There are many types of straws, such as those that have been processed like a bellows in the middle and bent to make them easier to drink, those that shrink in two steps, and those that have a spoon-shaped tip. Seems to be centered on a round cylindrical shape.
[0003]
[Problems to be solved by the invention]
In the case of a conventional straw with a rounded cylindrical end, if the material is a little hard, such as a 500 ml paper pack, the tip of the straw may be bent to insert it, or if the mouth is released from the straw during drinking and drinking, the inside of the pack When the air flowed into the room, a "squeaking sound" came out, and when the user suddenly squeezed the paper pack, a drink spewed out from the end of the straw.
[0004]
[Means for Solving the Problems]
Make the sides of the body evenly constricted from both directions so that both ends of the straw are gourd-shaped.
[0005]
【Example】
An example of use is shown in Figure 2.
[0006]
【The invention's effect】
The effect of the straw, which was devised this time and has a constricted cross section like a gourd, can be expected in cafeterias and restaurants as well as for paper packs. First of all, the same material as the conventional cylinder and the same thickness can be strengthened by vertically constricting it. (B) Therefore, it does not bend in the middle of the straw even when inserted into a hard paper pack. In addition, after inserting this constricted straw into the paper pack, lightly rotate the straw to the left and right with your fingertips to make the insertion opening on the paper pack circular (c), and between the constricted straw and the round hole of the paper pack. A gap is created. As a result, the outside air is sent into the pack through the gap at the same time as the sucking operation, and it is released from the unpleasantness of sucking and the danger of unexpected reverse injection due to the high airtightness. Also, in the case of a paper pack with an attached straw, even if the total thickness of the straw and the width of the straw is the same as before, the cross-sectional area of this straw is more than doubled. You can drink a lot with the sucking action. In addition, the wider width of the straw increases the area of the fingertip, which makes it easier to pinch, and improves the fit between the straw and the lips even when the straw is put in the mouth, enabling comfortable drinking. Also, since the cross section is non-circular, even if you accidentally drop it on a table in a restaurant, you do not have to worry about rolling down to the floor.
