Further, by inserting the pull tab c4 into the slit 34, the intermediate unit 3 is firmly fixed to the beverage can C.

(Action)
Next, the state in which the main body unit 2 and the intermediate unit 3 are attached to the beverage can C will be described with reference to FIG. 7, and the operation thereof will be described. First, the intermediate unit 3 is fitted into the drinking spout c2 of the beverage can C. Specifically, the base of the pull tab c4 is inserted into the slit 34, and the insertion tongue portion 33 is inserted between the lid portion c3 and the pull tab c4. Then, the hooking arm portion 32 on the opposite side is hooked on the upper edge c1 and fixed. Then, since the intermediate unit 3 is in close contact with the drinking port c2 of the beverage can C without a gap, only the tubular portion 31 is in a state where the inside and the outside of the beverage can C are communicated with each other.

Next, the main body unit 2 is placed over the intermediate unit 3 so as to cover it. That is, the ridge 21b of the fitting portion 21 of the main body unit 2 is hooked on the upper edge c1 of the beverage can C and fixed. Here, by aligning the position of the recess 21a with the position where the intermediate unit 3 is installed in the upper edge c1, the intermediate unit 3 (the hooking arm portion 32) is accommodated (fitted) in the recess 21a. Become. When the positions are aligned in this way, the tubular portion 31 of the intermediate unit 3 is automatically inserted into the through hole 23a of the partition wall 23 of the main body unit 2 without a gap.

In this way, the suction device 1 for the beverage can is completed. Alternatively, after that, the suction device 1 for a beverage can is completed by screwing and fixing the nipple unit 4 (see FIGS. 1 and 2) (see FIGS. 1 and 2) not shown to the mounting portion 22 of the main body unit 2. In this state, even if the beverage can C is tilted, the beverage does not leak into the gap between the partition wall portion 23 and the lid portion c3. Beverages can be drunk via the nipple unit 4 in order.

(effect)
Next, the effects of the suction device 1 for beverage cans of this embodiment will be listed and described.

(1) As described above, the suction device 1 for a beverage can of the present embodiment has a fitting portion 21 fitted to the upper edge c1 of the beverage can C, and an inner space and a through hole of the fitting portion 21. A main body unit 2 integrally having a cylindrical mounting portion 22 to which the nipple unit (4) is mounted, which communicates via 23a; one end is fitted to the drinking port c2 of the beverage can C. And an intermediate unit 3 having a tubular portion 31 whose other end is fitted into the through hole 23a; With such a configuration, the suction device 1 for a beverage can can be used after being attached to a commercially available beverage can C.

Further, in this embodiment, the provision of the intermediate unit 3 prevents the surface of the lid portion c3 from coming into contact with the beverage, which is extremely hygienic. That is, by directly connecting (contacting and connecting) the main body unit 2 and the drinking spout c2 by the tubular portion 31 of the intermediate unit 3, the beverage does not come into contact with the surface of the lid portion c3.

(2) The intermediate unit 3 is located on the opposite side of the hooking arm portion 32 hooked to the upper edge c1 of the beverage can C and the hooking arm portion 32, and the lid portion c3 and the pull tab c4 of the beverage can. Further has an insertion tongue portion 33 to be inserted into the gap between the two. Therefore, by fixing the opposite first end and the second end of the intermediate unit 3 to the beverage can C, the intermediate unit 3 can be accurately and surely arranged at the position of the drinking spout c2. Further, by fixing the two opposing points, the intermediate unit 3 can be firmly fixed to the beverage can C.

(3) Further, the intermediate unit 3 is formed with a slit 34 into which the pull tab c4 of the beverage can C is inserted. Therefore, the pull tab c4 does not hinder the positioning and fixing of the intermediate unit 3. Further, if the base of the pull tab c4 is inserted into the slit 34, the intermediate unit 3 can be more firmly fixed to the beverage can C.

(4) Further, as will be described later with reference to FIG. 10, the main body unit 2 further has a tubular hole 23b that communicates with the through hole 23a and extends toward the intermediate unit 3, and the tubular portion 31 of the intermediate unit 3 has a tubular portion 31. It is preferable that it is inserted into the cylinder hole 23b. With such a configuration, the lap lengths of the intermediate units 3 become longer, so that leakage is less likely to occur, the cylinder portion 31 of the intermediate unit 3 is more easily deformed, and it is easier to align with the cylinder hole 23b. This has the advantage of reducing wasted space.

(5) Further, since the planar shape of the intermediate unit 3 is wider than the drinking spout c2 of the beverage can C and is formed so as to cover the entire drinking spout c2, the intermediate unit 3 is placed at a predetermined position. If arranged, the leakage of the beverage can be surely prevented. Furthermore, the shape of the drinking spout c2 differs depending on the beverage can C, and by forming the intermediate unit 3 widely in this way, the difference in shape can be absorbed.

(6) Further, since the recess 21a for accommodating the intermediate unit 3 is formed in the fitting portion 21 of the main body unit 2, this does not hinder even when the intermediate unit 3 is installed. In addition, the main body unit 2 can be firmly fixed to the beverage can C. Conversely, without the recess 21a, it becomes difficult to fix the main body unit 2 to the beverage can C with the intermediate unit 3 installed.

(7) Further, by further providing the nipple unit 4 to be attached to the attachment portion 22 of the main body unit 2, the suction device 1 for a beverage can can be used immediately without separately purchasing and preparing the nipple unit 4. Can be done.

(8) Further, since the nipple unit 4 is detachably screwed to the mounting portion 22 of the main body unit 2, the nipple unit 4 should be prepared even when the nipple unit 4 is worn out. For example, the suction device 1 for beverage cans can be continuously used.

(9) Further, if the main body unit 2 is formed into a plurality of types having mounting portions (22) having different diameters corresponding to the nipple units (4) having a plurality of diameters and can be replaced. , Various types of nipple units (4) can be adapted.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes to the extent that the gist of the present invention is not deviated are made in the present invention. included.

For example, in the embodiment, a relatively large diameter type having a diameter substantially the same as the diameter of the beverage can C as the diameter of the nipple unit 4 has been described, but the diameter is not limited to this. Specifically, as shown in FIGS. 8 to 9, the present invention can also be applied to a type of nipple unit 4 having a diameter smaller than the diameter of the beverage can C. In this case, the suction device 1A for a beverage can may include a main body unit 2A having a slightly smaller diameter of the mounting portion 22. As described above, it is preferable to prepare various types of main body units according to the size of the nipple unit 4.

Further, in the embodiment, the case where the main body unit 2, the intermediate unit 3, and the nipple unit 4 are provided as the configuration of the suction device 1 for the beverage can has been described, but the present invention is not limited to this, and the nipple unit 4 is sold separately. It does not have to be included in the set.

Further, the form of the suction device 1B for a beverage can as shown in FIG. 10 is also possible. In the suction device 1B for a beverage can, the cylindrical hole 23b as a through hole formed in the partition wall portion 23 of the main body unit 2 extends in a cylindrical shape (the inner surface is tapered), and the tubular portion 31 of the intermediate unit 3 is long. Elongates (the outer surface is tapered). The cylinder hole 23b and the cylinder portion 31 are configured to wrap each other with a sufficient length. With such a configuration, the lap lengths of the intermediate units 3 become longer, so that leakage is less likely to occur, the cylinder portion 31 of the intermediate unit 3 is more easily deformed, and it is easier to align with the cylinder hole 23b. This has the advantage of reducing wasted space.

In the embodiment and the modified example of FIG. 10, the case where the intermediate unit 3 has the hook arm portion 32 and the slit 34 has been described, but the present invention is not limited to this, and the intermediate unit 3 has the drinking spout c2. It suffices as long as the main body unit 2 (2A) can be connected, and the hook arm portion 32 and the slit 34 may not be provided.
