Abstract

The invention of this straw is designed to turn the straw into one of reusable tableware, thereby reducing or even avoiding the use of disposable plastic straws, reducing their negative impact on the environment and health, and improving people's lives. Reducing the amount of disposable plastic straws is one of the most effective ways to reduce the damage of plastic waste to the nature. The straw in this invention has a pair of tabs affixed to the edge of the straw opening for easy opening of the straw.

Claims (36)

1. A washable and reusable straw comprises:

an elongated hollow tube, made of a semi-rigid material, with at least one closeable opening having two opposing edges along a tube longitudinal wall which has a predetermined thickness; at least one pair of tabs, one on each edge of the opening, affixed to slightly different positions of the edges for separating the opening apart;

a connective joint along the tube longitudinal wall on the opposing side of the opening allowing the tube open widely when the closeable opening being unclosed, where the connective joint has a thinner thickness than the predetermined thickness of the tube longitudinal wall;

wherein the opening can be closed for liquid passing through the tube where the tube can be opened for cleaning by pushing the tabs away from each other.

2. The straw of claim 1 , wherein the pair of tabs is perpendicularly affixed to different positions of the edges of the opening for separating the opening apart.

3. The straw of claim 1 , wherein the closeable opening is straight along the tube longitudinal wall.

4. The straw of claim 1 , wherein the elongated hollow tube has a cross-section shape selected from the group consisting of round, oval, square, rectangle, triangle, pentagon, hexagon and heart-shaped.

5. The straw of claim 1 , wherein the closeable opening can be magnetically closed by affixing opposite magnetized materials along each edge of the opening.

6. The straw of claim 1 , wherein the edges of the closeable opening further comprise: a groove along one edge of the closeable opening; and a convex member along the other edge of the closeable opening; wherein the convex member fits into the groove to securely close the opening.

7. The straw of claim 1 , wherein the edges of the closeable opening further comprise: a pair of an interlock mechanism wherein two edges of the closeable opening lock together to seal the opening.

8. A washable and reusable straw comprises:

an elongated hollow tube, made of a semi-rigid material, with at least one closeable opening having two opposing edges along a tube longitudinal wall which has a predetermined thickness;

at least one pair of tabs, one on each edge of the opening, affixed to slightly different positions of the edges for separating the opening apart;

a plurality of connective joints along the tube longitudinal wall equally situated on the side of the tube longitudinal wall allowing the pipette open widely when the closeable opening being unclosed, where the connective joints have thinner thicknesses than the predetermined thickness of the tube longitudinal wall;

wherein the opening can be closed for liquid passing through the tube where the tube can be opened for cleaning by pushing the tabs away from each other.

9. The straw of claim 8 , wherein the pair of tabs is perpendicularly affixed to different positions of the edges of the opening for separating the opening apart.

10. The straw of claim 8 , wherein the closeable opening is straight along the tube longitudinal wall.

11. The straw of claim 8 , wherein the elongated hollow tube has a cross-section shape selected from the group consisting of circle, oval, square, rectangle, triangle, pentagon, hexagon and heart-shaped.

12. The straw of claim 8 , wherein the closeable opening can be magnetically closed by affixing opposite magnetized materials along each edge of the opening.

13. The straw of claim 8 , wherein the edges of the closeable opening further comprise: a groove along one edge of the closeable opening; and a convex member along the other edge of the closeable opening; wherein the convex member fits into the groove to securely close the opening.

14. The straw of claim 8 , wherein the edges of the closeable opening further comprise: a pair of an interlock mechanism wherein two edges of the closeable opening lock together to seal the opening.

15. A washable and reusable straw comprises:

an elongated hollow tube, made of a semi-rigid material, with two closeable openings, which can be magnetically closed by affixing opposite magnetized materials along each edge of the openings, on the opposite side of a tube longitudinal wall, having two opposing edges along the tube longitudinal wall on each opening;

at least one pair of tabs, one on each edge of one opening, affixed to slightly different positions of the edges for separating the opening apart;

wherein the opening can be closed for liquid passing through the tube where the tube can be opened for cleaning by pushing the tabs away from each other.

16. A washable and reusable straw comprises:

an elongated hollow tube, made of a semi-rigid material, with two closeable openings on the opposite side of a tube longitudinal wall, having two opposing edges along the tube longitudinal wall on each opening, wherein the edges of the closeable openings further comprise:

a groove along each edge of the closeable openings; and

a convex member along the other edge of the closeable openings;

wherein the convex members fit into the grooves to securely close the opening;

at least one pair of tabs, one on each edge of one opening, affixed to slightly different positions of the edges for separating the opening apart;

wherein the opening can be closed for liquid passing through the tube where the tube can be opened for cleaning by pushing the tabs away from each other.
