DETACHABLE STRAW
A straw has a tubular body, at least one connection tab, and an engagement assembly. The tubular body has a thickness, a through hole, and a cutout. The through hole is defined through the tubular body and has two openings defined respectively in two ends of the tubular body. The cutout is formed longitudinally in the tubular body to form two longitudinal surfaces on the tubular body respectively at two sides of the cutout. The at least one connection tab is formed on the tubular body and extends longitudinally along the tubular body. Each one of the at least one connection tab has a thickness smaller than the thickness of the tubular body. The engagement assembly is formed on the longitudinal surfaces on the tubular body to connect the longitudinal surfaces of the tubular body together.
The present invention relates to a straw, and more particularly to a detachable straw that can be detached easily for cleaning.
2. Description of Related ArtWith reference to
To clean the inner surface of the straw 60, the engagement block 61 and the engagement recess 63 are disengaged from each other, and the straw 60 is expanded to allow the inner surface of the straw 60 to be cleaned.
However, when the straw 60 is expanded, the straw 60 will rebound and cause the engagement block 61 and the engagement recess 63 to move toward each other due to the resilience of the straw 60. Therefore, to keep the straw 60 at the expanded condition is laborious, so to clean the conventional detachable straw 60 is inconvenient.
To overcome the shortcomings, the present invention tends to provide a detachable straw to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONThe main objective of the invention is to provide a detachable straw that is easily kept at an expanded condition and is convenient to be cleaned.
The straw has a tubular body, at least one connection tab, and an engagement assembly. The tubular body has a thickness, a through hole, and a cutout. The through hole is defined through the tubular body and has two openings defined respectively in two ends of the tubular body. The cutout is formed longitudinally in the tubular body to form two longitudinal surfaces on the tubular body respectively at two sides of the cutout. The at least one connection tab is formed on the tubular body and extends longitudinally along the tubular body. Each one of the at least one connection tab has a thickness smaller than the thickness of the tubular body. The engagement assembly is formed on the longitudinal surfaces on the tubular body to connect the longitudinal surfaces of the tubular body together.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The tubular body 10 has two ends, a thickness, a through hole 11, and a cutout 30. The through hole 11 is defined through the tubular body 10 and has two openings defined respectively in two ends of the tubular body 10. The cutout 30 is formed longitudinally in the tubular body 10 to form two longitudinal surfaces 31 on the tubular body 10 respectively at two sides of the cutout 30.
With further reference to
Alternatively, the tubular body 10 has at least one inner recess 15 defined in an inner surface of the through hole 11 to form the at least one connection tab 20 respectively. Each inner recess 15 has a width of 1 millimeter (mm) to 3 mm and is trapezoidal or rectangular in shape. Preferably, each inner recess 15 is trapezoidal in shape.
Alternatively, the tubular body 10 has at least one inner recess 15 and at least one outer recess 13 aligned respectively with the at least one inner recess 15. Each connection tab 20 is formed by a pair of aligned inner recess 15 and outer recess 13.
The engagement assembly 40 is formed on the two longitudinal surfaces 31 on the tubular body 10 to connect the two longitudinal surfaces 31 of the tubular body 10 together. Preferably, the engagement assembly 40 comprises a male engagement element 41 and a female engagement element 43 formed respectively on the two longitudinal surfaces 31. The male engagement element 41 may be a block formed longitudinally on the corresponding longitudinal surface 31 and extends to the two ends of the tubular body 10. The female engagement element 43 may be a recess formed longitudinally in the corresponding longitudinal surface 31 and extends to the two ends of the tubular body 10. The configurations of the engagement elements 41,43 are not limited in the present invention.
