Description

Triple straw {Triple straw}

The present invention relates to a straw, and more particularly, to a three-stage straw to prevent the separation phenomenon between each member constituting the straw to facilitate the storage and use of the straw.

In general, the beverage container is attached to the outer surface of the container forming a cup or pack form, so that you do not have to carry a straw when purchasing a drink, and also easy to store the straw. At this time, in order to attach the straw to the outside of the container, the straw was overlapped once, the straw was used two-stage straw shorter than the length of the beverage container.

However, when the conventional two-stage straw is attached to the outer surface of the container, the straw protrudes out of the beverage container, and even if a little rubbing or impact is applied, the attached straw falls and the straw is easily lost. There was a hassle to attach a straw to the container.

In addition, in order to solve the above problems, it is proposed to configure the straw in three stages as described in Republic of Korea Utility Model Publication No. 20-0325352 to further reduce the length to be stored inside the lid of the container.

In this case, the third stage straw has a first connecting portion 400 for connecting the first member 100 and the second member 200, and a second connecting the second member 200 and the third member 300. It includes a connection portion 500, the first and second connection portion 400, 500 is provided with a first and second locking jaw 410, 510, respectively, each connection portion 400, 500 to use a straw When it is removed, it is designed to prevent it from being pushed in the reverse direction.

However, the conventional three-stage straw prevents the second member 200 from being drawn out to the upper portion of the first member 100 by the bent portion 110 formed at the upper end of the first member 100 when adjusting the length. Although the third member 300 is relatively small in diameter and does not have a configuration to control the third member 300 to the outside through the upper portion of the second member 200 and the first member 100. There is a fear that a safety accident that protrudes and the third member 300 is caught on the user's neck.

Therefore, the present invention has been devised to solve the conventional problems as described above, an object of the present invention is to form a third member by integrally extending the first inclined end on the upper end of the second member constituting the straw, It is possible to control the separation between each member, as well as to provide a three-stage straw that can be easily stored and used straw.
