Description

[Detailed Description of the Invention] The present invention relates to an improvement of a two-stage telescopic suction pipe that combines a large-diameter pipe and a small-diameter pipe.

Most conventional suction pipes are formed from a single elongated cylindrical body. The length of such a single cylindrical suction pipe must be at least greater than the depth of the beverage container. However, long pipes are not preferred because they are inconvenient for storage, portability, transportation, attachment to containers, etc.

For the reasons mentioned above, a two-stage telescopic suction pipe was developed, which consists of a large-diameter pipe and a small-diameter pipe, and the small-diameter pipe is inserted into the large-diameter pipe.

An example of such a two-stage extensible suction pipe has a structure as shown in FIG. That is, FIG. 1 is an enlarged sectional view of a part of a two-stage telescopic suction pipe, in which 1 is a large diameter pipe, and 2 is a larger diameter pipe than the inner diameter of the large diameter pipe 1. This is a small diameter pipe having a slightly small outer diameter, and as shown in the figure, a small diameter pipe 2 is inserted into a large diameter pipe 1 to form a two-stage telescopic structure. Also, the tip 2a of the small diameter pipe 2 on the side inserted into the large diameter pipe 1 has a shape that is widened, for example, into a flap shape, so that when the small diameter pipe 2 is inserted into the large diameter pipe 1, this widened part becomes large. The small diameter pipe 2 is crimped onto the inner wall of the large diameter pipe 1, thereby preventing the small diameter pipe 2 from easily falling out from the large diameter pipe 1 under its own weight.

This two-stage telescoping suction pipe allows the small diameter pipe 2 to be moved relative to the large diameter pipe 1 to shorten the overall length for convenient storage, portability, etc., and also for drinking water etc. When suctioning, the small diameter pipe 2 is stretched to increase its overall length.

Another example of a two-stage retractable suction pipe has a structure as shown in FIG. That is, the tip portion 3a of the large-diameter pipe 3 is formed to be slightly thinner than the other portions, and the inner wall surface of this tip portion 3a lightly contacts the outer wall surface of the small-diameter pipe 4, so that both pipes 3 and 4 touch each other. It has a structure that allows it to slide. The two-stage expandable suction pipe shown in FIG. 2 has the tip portion 3a of the large diameter pipe 3 contacting and sliding with the small diameter pipe 4, so that even when both pipes are expanded and contracted, A stable state is possible after that.

The two-stage telescopic suction pipes described above have almost the same appearance, with the only difference being the diameter of the two pipes. Furthermore, although the wall thickness of each pipe is shown as thick in Figures 1 and 2, it is actually quite thin, which is why it is difficult to determine whether it is a two-stage pipe or a single pipe. Generally, people do not notice it immediately. Therefore, it is conceivable to use the small diameter pipe as it is without pulling it out when using it.

Furthermore, when such two-stage telescopic suction pipes are assembled, it is difficult to immediately distinguish between large diameter pipes and small diameter pipes, which is undesirable for the assembly work.

The present invention was developed in view of the above-mentioned circumstances, and it is possible to distinguish between the large diameter pipe and the small diameter pipe during assembly work, etc. by making the external appearance of the large diameter pipe and the small diameter pipe different colors. To provide a two-stage extensible suction pipe which is easy to use and also makes it possible to improve the aesthetic appearance of the combined pipes.

Hereinafter, the details of the two-stage telescopic suction pipe of the present invention will be explained based on embodiments. Third
The figure is a perspective view of an embodiment of the present invention, and in this figure, 11 is a large diameter pipe, 12 is a small diameter pipe, and these are telescopically combined. It has the same or similar structure. In this suction pipe, the large diameter pipe 11 is red and the small diameter pipe 12 is white.
By making the large-diameter pipe 11 and the small-diameter pipe 12 different colors in this way, it is possible to indicate that this pipe is a two-stage telescopic pipe and can be used by pulling out the small-diameter pipe 12. It will be implied. Also, it is preferable because it is easy to identify when combining both pipes. Further, the color of both pipes is red and white, which is just one example, and a desirable aesthetic appearance can be achieved by selecting the colors.

Instead of using different colors for the large-diameter pipe and the small-diameter pipe as in the above-described embodiment, the same color may be used with different shading. Furthermore, by leaving one pipe uncolored and coloring only the other pipe while making the most of the color of the material, different color combinations are possible. In this case, the amount of coloring material can be reduced to half.

In order to form the two-stage extensible suction pipe of the present invention that combines pipes of different colors, it is necessary to color the pipes of each diameter when forming them by means such as extrusion molding. good.

When forming an uncolored two-stage telescopic suction pipe as shown in FIGS. 1 and 2, a large-diameter pipe and a small-diameter pipe are molded separately and then combined. Therefore, when making each pipe, it is sufficient to use a material containing a coloring agent or a material that has already been colored, so the manufacturing process does not change at all. In addition, if you want to make the most of the color of the material on one side, it is only necessary to color the other side.

Materials for this suction pipe include synthetic resin,
Examples include paper.

As explained above, the two-stage telescopic suction pipe of the present invention uses different colors for the large diameter pipe and the small diameter pipe, which implies that it is a two-stage telescopic suction pipe. It is extremely convenient to use. Also, the combination work becomes easier. Furthermore, it is effective from an aesthetic point of view. Moreover, in manufacturing, it can be manufactured without adding any special steps other than the manufacture of uncolored pipes.
