A straw with an easily cleanable interior, comprising: an outer tubular wall; a non-flat inner pipe wall; and a channel defined by the non-planar inner tube wall; the inner pipe wall has several raised parts for the user to press and rub the outer pipe wall to rub the raised parts to the surface of the inner pipe wall so as to eliminate the adhered matter effectively.

Description

Straw with easy-to-clean interior

Technical Field

The utility model relates to the technical field of straws, in particular to a straw with an easy-to-clean interior.

Background

Given the increasing strictness of environmental regulations, plastic straws have been used in many countries to restrict or prohibit their disposal.

In order to comply with regulations, it is known to make disposable straws from environmentally friendly materials, such as paper or corn flour. However, the discarded straws still produce a large amount of waste due to the large consumption of straws.

In addition, a straw assembly has been proposed to facilitate cleaning of the interior. For example, taiwan patent I674868 discloses a detachable straw, which is mainly composed of two magnetic half-tubes and a buckle ring. However, the detachable straw disclosed in the patent has problems of high cost and easy dislocation during assembly.

To solve the above problems, there is a need in the art for a novel straw structure that is easy to clean inside.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a straw, which has a plurality of protrusions on an inner wall of the straw, so that a user can press and rub an outer wall of the straw to rub the protrusions against a surface of the inner wall, thereby effectively removing the adhered substance on the inner wall.

Another objective of the present invention is to disclose a straw that can be folded and stored in a box.

To achieve the above object, an easy-to-clean straw is provided, which comprises:

an outer tubular wall;

a non-flat inner pipe wall; and

a channel defined by the non-planar inner tube wall;

the inner pipe wall has several raised parts for the user to press and rub the outer pipe wall to rub the raised parts to the surface of the inner pipe wall so as to eliminate the adhered matter effectively.

In a possible embodiment, the pipette may be made of silicone or TPE (thermoplastic elastomer).

In one embodiment, the protrusions are triangular in shape.

In one embodiment, the protrusion is square.

In one embodiment, the protrusion is semi-circular.

In one embodiment, the protrusion has a polygonal shape.

In possible embodiments, the outer tube wall may have a circular cross-sectional appearance or a textured cross-sectional appearance.

In order to better understand the above and other aspects of the present invention, the following detailed description of the embodiments is made with reference to the accompanying drawings:

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, fig. 1 is an external view of an embodiment of an easy-to-clean internal straw according to the present invention; FIG. 2 is another schematic external view of the easy-to-clean internal straw of FIG. 1; and FIG. 3 is a cross-sectional view of the easy-to-clean internal straw of FIG. 1.

As shown in FIG. 1, the easy-to-clean internal straw has an outer tubular wall 100, a non-flat inner tubular wall 110 and a channel 120. In addition, the straw provided in this embodiment may be made of silicone or TPE (thermoplastic elastomer) so that it is flexible and can be conveniently stored in a small box.

The outer tube wall 100 may be a flat surface with a circular cross-sectional appearance or a textured surface with a non-circular cross-sectional appearance, wherein the non-circular cross-sectional appearance may be a heart, flower, or other geometric shape.

The non-flat inner pipe wall 110 is annularly provided with a plurality of protrusions 111, in this embodiment, the protrusions 111 are triangular.

A channel 120 is defined by the non-flat inner tube wall 111 for passage of fluid.

The utility model provides a straw with easy cleaning inside, which has the following principle: the plurality of protrusions 111 are disposed around the inner pipe wall 110 for allowing a user to rub the protrusions 111 against the surface of the inner pipe wall 110 by squeezing and rubbing the outer pipe wall 100, so as to effectively remove the adhesive on the inner pipe wall 110.

In light of the above description, the present invention further provides other embodiments of the protrusion 111 on the inner pipe wall 110. Please refer to fig. 4, which is a cross-sectional view of another embodiment of the easy-to-clean internal straw according to the present invention, wherein the protrusion 111 is square; referring to fig. 5, which is a cross-sectional view of another embodiment of the easy-to-clean internal straw according to the present invention, the protrusion 111 is in a semicircular shape. In addition, the protrusion 111 provided in the present invention may have a polygonal shape.

By the design disclosed above, the present invention has the following advantages:

1. the straw provided by the utility model can be provided with a plurality of protrusions on the inner pipe wall of the straw, so that a user can press and rub the outer pipe wall of the straw flexibly to enable the plurality of protrusions to rub the surface of the inner pipe wall, thereby effectively removing the attached matters on the non-flat inner pipe wall.

2. The straw provided by the utility model can be folded and contained in a box body.

In summary, although the present invention has been described with reference to the embodiments, the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the present invention should be determined by the scope of the appended claims.
