Description

[Detailed Description of the Invention] This invention relates to an improvement of a two-stage retractable straw for beverages in a beverage container that combines a large-diameter pipe and a small-diameter pipe. Most conventional beverage straws are formed of a single long, thin tubular body. Such a beverage straw made of a single tubular body must be at least longer than the depth of the beverage container. However, a long straw is not preferable because it is inconvenient to store, carry, transport, and attach to the container. For the above reasons, a two-stage retractable straw for beverages has been developed that is made of a large-diameter pipe and a small-diameter pipe, with the small-diameter pipe inserted into the large-diameter pipe. An example of such a two-stage retractable straw for beverages has a structure as shown in Figure 1. That is, Fig. 1 is a cross-sectional view showing an enlarged portion of a two-stage retractable straw for beverages, in which 1 is a large-diameter pipe, and 2 is a small-diameter pipe with an outer diameter slightly smaller than the inner diameter of the large-diameter pipe 1. As shown in the figure, the small-diameter pipe 2 is inserted into the large-diameter pipe 1 to form a two-stage retractable structure. Also, the tip 2a of the small-diameter pipe 2 on the side inserted into the large-diameter pipe 1 is shaped like a trumpet, for example, and the small-diameter pipe 2 is inserted into the large-diameter pipe 1.
When the small diameter pipe 2 is inserted into the large diameter pipe 1, the expanded portion presses against the inner wall of the large diameter pipe 1, so that the small diameter pipe 2 does not easily fall out of the large diameter pipe 1 under its own weight. This two-stage retractable straw for beverages can be made convenient for storage, carrying, etc. by moving the small diameter pipe 2 relative to the large diameter pipe 1 to shorten the overall length.
When sucking drinking water, the small diameter pipe 2 is stretched to increase the overall length. Another example of a two-stage retractable straw for drinking is the one shown in Fig. 2. That is, the tip portion 3a of the large diameter pipe 3 is formed slightly thinner than the other portions, and the inner wall surface of this tip portion 3a is lightly in contact with the outer wall surface of the small diameter pipe 4, so that both pipes 3, 4 can slide against each other. In the two-stage retractable straw for drinking shown in Fig. 2, the tip portion 3a of the large diameter pipe 3 contacts and slides against the small diameter pipe 4, so that both pipes can be in a stable state both when and after they are extended or retracted. The two-stage retractable straw for drinking as described above has almost the same appearance, with only the diameters of the two pipes being different. Moreover, although the thickness of each pipe is shown as thick in Figs. 1 and 2, it is actually quite thin,
Therefore, it is generally not immediately noticeable whether it is a two-stage straw or a single straw. Therefore, it is considered that the small diameter pipe is not pulled out when using it, and is used in a short length. In addition, when assembling such a two-stage retractable straw for beverages, it is difficult to immediately distinguish whether the large diameter pipe is the small diameter pipe, which is not preferable for assembling work. The present invention has been made in consideration of the above-mentioned circumstances, and provides a two-stage retractable straw for beverages in a beverage container, which makes it easy to distinguish the two pipes during assembling work by making the appearance of the large diameter pipe and the small diameter pipe different colors, and also makes it possible to improve the aesthetics of the combined pipes. The details of the two-stage retractable straw of the present invention will be explained below based on the embodiment. Figure 3 is a perspective view of an embodiment of the present invention, in which 11 is a large diameter pipe and 12 is a small diameter pipe that are combined in a retractable manner, and has the same or similar structure as that of Figure 1 or Figure 2, for example. In this drinking straw, the large diameter pipe 1 is red and the small diameter pipe 12 is white. By giving the large diameter pipe 11 and the small diameter pipe 12 different colors in this way, it is implied that the straw is a two-stage retractable type, and the small diameter pipe 12 can be pulled out for use. This is also preferable as it makes it easy to distinguish when combining the two pipes. Furthermore, the colors of the two pipes, red and white, are just one example, and a desirable aesthetic appearance can be presented by selecting the right color. Instead of giving the large diameter pipe and the small diameter pipe different colors as in the above embodiment, the same color with different shades may be used. Furthermore, one of the pipes may not be colored,
Different color combinations are also possible by leaving the color of the material as it is and coloring only the other. In this case, half the amount of coloring material is required. In order to form the two-stage telescopic straw of this invention, which combines pipes of different colors, the pipes of each diameter may be colored when they are formed by means of, for example, extrusion molding. Even when forming a two-stage telescopic straw that is not colored as shown in Figure 1 or Figure 2, the large-diameter pipe and the small-diameter pipe are formed separately and then combined. Therefore, when making each pipe, materials containing coloring materials or colored materials can be used, so the manufacturing process does not change at all. Furthermore, if the color of one of the materials is to be used as it is, only the other one needs to be colored. The material of this drinking straw is synthetic resin. As explained above, the two-stage telescopic straw of this invention has different colors for the large-diameter pipe and the small-diameter pipe, which suggests that it is a two-stage telescopic straw, making it extremely convenient to use. In addition, the assembly work becomes easier. It is also effective in terms of aesthetics. Moreover, the pipe can be manufactured without adding any special steps to the manufacture of uncolored pipes.
