EASY-TO-CLEAN DRINKING STRAW
An easy-to-clean drinking straw include a C-section tube having a slot and a resilient sheet with its front end combined with an inner edge of the slot as a unity. The resilient sheet is such configured that when rolled up toward the slot from its rear end and pressed into the C-section tube through the slot, the resilient sheet becomes tubular and gets positioned in the C-Section tube, and upon release of the pressing force applied thereto, the resilient sheet shows unfolding tendency due to its own resilience and thereby fits closely the inner wall of the C-section tube, so as to form the drinking straw. For cleaning, the resilient sheet rolled up and positioned in the C-section tube is pulled out through the slot of the C-section tube, and then the resilient sheet automatically unfolds and returns to a sheet due to its own resilience.
The present invention relates to easy-to-clean drinking straws, and more particularly to drinking straws that can be cleaned easily.
2. Description of Related ArtIt has become a worldwide trend to ban the use of plastic drinking straws. As results of initiatives promoted by environmental groups, many regions and countries such as EU, UK, India, Canada, US and Singapore have legislated against using plastic drinking straws.
Thus, when buying and having drinks outside, consumers have to bring their own reusable drinking straws, and there are now reusable drinking straws made of different materials on the market for consumers to choose.
However, while the existing reusable drinking straws are different from the plastic drinking straws in terms of material, they are structurally unchanged, which means they are still tubes with small diameters and not easy to clean. For washing such a drinking straw, a small brush has to be used to scrub the inner wall of the tube, and since visual check is relatively difficult, the cleaning result is not necessarily satisfactory.
In addition, in view that such a reusable drinking straw is designed for portable use, the small cleaning brush undesirable adds a burden and cause inconvenience to users, making users unwilling to carry the cleaning brush with them.
In this case, after use, the reusable drinking straw can be only roughly washed with water. Once the drinking straw is not properly cleaned at its inner wall, pathogenic bacteria can grow rapidly and sicken a user using the contaminated straw.
In view of the shortcomings of the prior art, the inventor uses his years of experience to invent a drinking straw that is suitable for repeated use and is easy to clean after use.
The invention as well as a preferred mode of use, further objectives and advantages thereof will be best understood by reference to the following detailed description of illustrative embodiments when read in conjunction with the accompanying drawings.
BRIEF SUMMARY OF THE INVENTIONThe present invention provides an easy-to-clean drinking straw, which has a rigid C-section tube and a resilient sheet whose front end is combined with the inner edge of the slot of the rigid C-section tube as a unity.
Particularly, the resilient sheet is such configured that its rear end can be rolled up toward the slot of the C-section tube, and pressed into the slot of the C-section tube. The rolled up, tubular resilient sheet then shows unfolding tendency due to its own resilience when the pressing force is released, so as to abut against and fit closely the inner wall of the C-section tube, thereby forming the drinking straw.
For cleaning the drinking straw, the rolled-up, tabular resilient sheet is pulled out from the C-section tube where it is positioned through the slot of the C-section tube. Then the resilient sheet unfolds on its own resilience, so that the C-section tube and the resilient sheet can be both cleaned thoroughly.

Claims
1. An easy-to-clean drinking straw comprising: a C-section tube and a resilient sheet, wherein the C-section tube has a slot whose inner edge is combined with a font end of the resilient sheet as a unity; and
- the resilient sheet being such configured that when rolled up toward the slot of the C-section tube from its rear end and pressed into the C-section tube through the slot, the resilient sheet becomes tubular and gets positioned in the C-Section tube, and upon release of pressing force applied thereto, the resilient sheet shows unfolding tendency due to its own resilience and thereby abuts against and fits closely an inner wall of the C-section tube, so as to form the drinking straw.
2. An easy-to-clean drinking straw comprising: a C-section tube and a resilient sheet, wherein the C-section tube has a slot whose inner edge is combined with a font end of the resilient sheet as a unity;
- the resilient sheet having its rear end formed with a raised edge; and
- the resilient sheet being such configured that when rolled up toward the slot of the C-section tube from its rear end and pressed into the C-section tube through the slot, the resilient sheet becomes tubular and gets positioned in the C-Section tube, and upon release of pressing force applied thereto, the resilient sheet shows unfolding tendency due to its own resilience and thereby abuts against and fits closely an inner wall of the C-section tube, so as to form the drinking straw.
3. An easy-to-clean drinking straw comprising: a C-section tube and a resilient sheet, wherein the C-section tube has a slot whose inner edge is combined with a font end of the resilient sheet as a unity;
