Description

  The present invention relates to a straw, and more particularly to a straw having an improved structure.

  As shown in FIG. 1, a conventional straw used for sucking liquid in a container or cerebrospinal fluid of cooked animal long bones is composed of a plastic tube 20 having a fluid passage 21 in the center. The straw generally has a diameter of about 0.5 cm, and when sucking a drink such as yogurt or tapioca milk tea, a diameter of 1.5 cm is relatively preferable.

  The working principle of a straw capable of sucking drinks and foods is to suck up and carry drinks and foods by making the internal atmospheric pressure smaller than the external atmospheric pressure. Specifically, the pressure in the straw is reduced by sucking out a portion of the air in the straw. At this time, since the external atmospheric pressure is larger than the atmospheric pressure in the straw, the weight of the atmospheric pressure presses and raises the liquid in the straw. When the suction of the air in the straw is stopped, the gas in the straw and the external gas become united, that is, the gas pressure in the straw and the external atmospheric pressure are the same. The liquid in the straw cannot rise, and the liquid in the straw drops. On the other hand, when sucking a drink with a straw with a hole in the wall, if the hole in the wall of the straw comes into contact with the atmospheric pressure, the gas in the straw and the external gas become one, and the gas pressure in the straw and the external atmosphere Since the pressure is the same, it is difficult to draw liquid from the container.

  In the 19th century America, many people enjoyed refreshing cocktails. At that time, I used to suck a cocktail with a hollow straw to avoid getting a cold cocktail. However, straw is not only easy to break, but it also moves to the cocktail. On the other hand, the straw made by the cigarette manufacturer Marvin Stone from a spiral of paper is hard to break and does not taste unpleasant. Thus, paper straws are often used when drinking other soft drinks in addition to cocktails.

  Since then, plastic products have become widespread, and flexibility, appearance, and manufacturing convenience are superior to paper straws, and instead of paper straws, they have evolved into plastic straws that are commonly seen today.

  On the other hand, tapioca, salmon, and pulp are often added to drinks to meet the diversification of drinks required by modern people. The well-known straw has a bottom that comes into contact with the bottom of the container, so tapioca, strawberries, and pulp that have settled on the bottom of the container are not sucked into the straw, but are clogged in the opening of the straw and block the straw.

  In addition, when drinking fruit tea with added fruit slices, the fruit slices in the fruit tea cannot be sucked out with a straw. In other words, the fruit slice cannot be taken out without drinking the drink. Therefore, it is very difficult to take out the fruit slice in the drink with a known straw.

  The present invention can solve the problem that by improving the structure of the straw, the solid matter in the drink is well packed in a known straw, and it cannot be taken up even if a relatively large solid matter such as a fruit slice in the drink is stabbed. The main purpose is to provide straws.

  In order to solve the above-described problems, a straw with an improved structure includes a straw body.

The straw body is made of a plastic material, has a hollow cylindrical shape, and has a plurality of forks at one end and a plurality of openings located therebetween. The fork has a main body and a tip. One end of the main body is connected to the straw main body, and the other end is connected to the tip, so that the overall widths match. The tip has an arc shape.

  In a relatively preferred embodiment, the fork has a plurality of teeth on the edge.

  In a relatively preferred embodiment, the openings are two in number and are located on opposite sides along the radial direction of the straw body. The fork has two numbers and is located on opposite sides along the radial direction of the straw body.

  In a relatively preferred embodiment, the fork has a number of four and is located two on opposite sides along the radial direction of the straw body. The opening has two first openings and two second openings. The two first openings are disposed on opposite sides along the radial direction of the straw body, and are located between the two forks on different sides. The two second openings are located on opposite sides along the radial direction of the straw body, and are located between the two forks on the same side.

  In a relatively preferred embodiment, the two first openings are formed larger than the two second openings.

  In a relatively preferred embodiment, the opening has a bottom that is arcuate.

  In a relatively preferred embodiment, the opening has a maximum depth between 1 and 2 times the inner diameter of the straw body.

  Due to the structural features described above, it is possible to solve the problem that a solid material in a drink is clogged in a known straw opening, and that a relatively large solid material such as a fruit slice in a drink cannot be picked up. .
