Description

Improved straw

This creation is about an improved straw with a suction function and a detachable set.

The straw is an indispensable daily necessities in the life of the user. The user can place the straw in a liquid such as a beverage or water inside the beverage cup or the container, and the hollow wall of the tube wall closed by the straw and having an opening at both ends. The structure allows the user to draw a liquid such as a beverage or water from various beverage cups or containers, and a liquid such as a beverage or water can enter the mouth of the user from the inside of the container along the inside of the straw tube wall.

However, in recent years, with the rise of environmental awareness, the common plastic straws that are discarded after one-time use have become a problem of environmental pollution. In order to reduce the problems caused by disposable plastic straws, the demand for repeated use of straws has increased, and there are reusable straws made of stainless steel and the like. However, the conventional straw has a slender closed tubular structure, which makes it difficult for the user to clean the inside of the straw, which is liable to cause bacterial growth and is not conducive to repeated use of the straw. The conventional stainless steel straw has a long brush that can be inserted into the inside of the straw to wash, but the long brush is not convenient to carry, and the inside of the straw can not be brushed by a common short brush, and there is still a problem of inconvenient cleaning.

The main purpose of the present invention is to provide an improved straw, which solves the problem that the existing straw can only be cleaned by using a long brush or the like due to its elongated closed structure, and the cleaning is inconvenient.

In order to achieve the purpose of the previous disclosure, the improved straw proposed by this creation includes:  An inner tube having an open end formed at each end thereof, the inner side of the inner tube forming an inner groove, and respectively communicating the inner portion of the inner tube and the two open ends of the inner tube, the inner groove Forming a groove edge on each side, wherein the inner groove is located at the same height and the sides of the groove are respectively connected with a line at the same height of the inner tube, and an angle between the two lines is greater than 0 degrees and less than 180 degrees;  An outer tube has an open end formed at each end of the outer tube, and an outer groove is formed on a side of the outer tube, and communicates with an inner portion of the outer tube and the open end of the outer tube respectively, the outer groove The sides are respectively formed with a groove edge, and the outer groove is located at the same height and the sides of the groove are respectively connected with a line at the same height of the outer tube, and an angle of more than 0 degrees and less than 180 degrees is formed between the two lines. The inner tube is detachably inserted into the inner tube, so that the outer groove of the outer tube and the inner groove of the inner tube are arranged in a staggered manner, so that the inner groove of the inner tube can be closed by the wall of the outer tube to form A hollow tube body having an opening at both ends.  

The advantage of this creation is that, because it comprises a detachable inner tube and an outer tube, the user can arrange the grooves in the inner tube by the grooves outside the outer tube and the inner grooves of the inner tube. It is closed by the wall of the outer tube, so that the inner tube and the outer tube are combined into a straw having a suction function. When the inside of the straw is to be cleaned, the user can take advantage of the general practice by pushing or pulling the inner tube or by pulling the inner tube out of the outer tube to remove the inner tube from the inside of the outer tube. The short brush passes through the inner groove on the inner tube and the outer groove on the outer tube to clean the inside of the inner tube and the outer tube. Compared with the conventional straw, the tool can only be used by a long brush or the like. It can be cleaned, and the improved straw of this creation effectively improves the convenience of cleaning the inside of the straw.

In the preferred embodiment of the present invention, the inner tube 10 is detachably inserted into the outer tube 20, and the outer groove 20 and the inner groove 12 of the inner tube 10 are arranged in a staggered manner. The inner groove 12 of the inner tube 10 can be closed by the tube wall of the outer tube 20, and a hollow tube body having an opening at both ends can be formed, and can be put into a liquid such as a beverage inside a container such as a beverage cup for suction.

As shown in FIG. 3 to FIG. 5, a groove edge 121 is formed on each side of the inner groove 12, and the groove sides 121 of the inner groove 12 at the same height are respectively connected with the center of the inner tube 10 at the same height. An angle θ2 greater than 0 degrees and less than 180 degrees is formed between the two lines, and a groove edge 221 is formed on each side of the outer groove 22, and the outer groove 22 is located at the same height on both sides of the groove 221 and the outer tube respectively 20 is located at the center of the same height and is formed into a line. An angle θ1 greater than 0 degrees and less than 180 degrees is formed between the two lines, and the outer tube 20 is outside the groove 22 as long as the inner tube 10 is inserted inside the outer tube 20. The grooves 12 in the inner tube 10 are arranged offset from each other such that the inner groove 12 of the inner tube 10 can be closed by the tube wall of the outer tube 20, and a hollow tube body having an opening at both ends is formed, and the angle θ1 and the angle θ2 are formed. The sizes may be the same or different, and as shown in FIG. 5, the angles θ1 and the angles θ2 are different.

As shown in FIG. 1 and FIG. 2, in the preferred embodiment of the present invention, the groove edges 121 on both sides of the inner groove 10 of the inner tube 10 are respectively straight segments, and the outer tube 20 is on both sides of the groove 22 The groove edges 221 are respectively straight segments. In another preferred embodiment, as shown in FIG. 6 and FIG. 7 , the groove sides 121 on both sides of the inner groove 10 of the inner tube 10 respectively have a curved line segment, and the outer tube 20 has grooves on both sides of the groove 22 . The sides 221 are each a curved line segment.

In a preferred embodiment of the present invention, the inventive improved straw can also form a spoon portion that projects outwardly at one of the open ends of the inner tube 10 or the outer tube 20.

As shown in FIG. 8 and FIG. 9, in another preferred embodiment of the present invention, the inner tube 10 and the outer tube 20 are both conical tubes.
