Description

Combined Telescopic Straw

The utility model relates to a combined telescopic straw, which is suitable for a can or a full-open bottle body and a packaged liquid container product, and belongs to daily necessities and the like.

Although the existing pop-top cans or packaged liquid containers have the effect of being convenient to carry and contain liquid, in actual use, most of them need to be sucked by inserting straws. The general straws are mostly unsterilized, and are attached to the box surface of the package or are packaged in paper bags, that is, straight tubes or snake-shaped variable heads. Putting it into a container for use, thus deriving the derivative problem of "hand contact type secondary pollution", there is no good solution so far.

The utility model combined telescopic suction pipe, its invention purpose is exactly in order to solve above-mentioned existing problem, and the purpose of its design is to replace existing suction pipe with built-in telescopic suction pipe. The combined telescopic straw is a kind that can be placed inside the pop can, and the straw can automatically stretch out when the mouth of the pop can is opened, and has good elastic effect and smooth sucking effect.

Further illustrate the design scheme and the technical characteristics of this utility model below in conjunction with accompanying drawing.

See Fig. 1, the three-dimensional system exploded view of suction pipe, and 10 in this figure is outer sleeve; As shown in Figure 1, the utility model combined telescopic suction pipe is made up of suction pipe 20; Wherein, the suction pipe 20 can be made of a hollow straight pipe by hard PP (polypropylene) material, and the flexible coil 30 can be made of a plurality of continuous annular patterns by elastic PE (polyethylene), and its top can be formed with the suction pipe 20 The socket mouth 31 that the end fits, and the telescopic flexible tube 30 only forms openings on the top and bottom surfaces, and the peripheral positions are all in a closed state, and the upper end of the outer sleeve 10 forms a tube body of a narrowing part 11, which can be used for the suction pipe 20 The flexible flexible tube 30 is inserted into the bottom end of the outer sleeve 10 and only the suction tube 20 protrudes from the upper end, and the outer diameter of the flexible flexible tube 30 is slightly smaller than the inner diameter of the outer sleeve 10 in a stretched state.

After the above-mentioned structural parts are combined, as shown in Figure 3, when the suction pipe 20 has not been subjected to external pressure, it is filled in the entire outer casing 10 due to the stretching elasticity of the flexible flexible tube 30 itself. When the flexible flexible tube 30 is squeezed relatively When the compression is in a compressed state, and the flexible flexible tube 30 is one-third of the length after compression, the outer ring surface of the flexible flexible tube 30 is also slightly expanded so that the inner wall surface of the outer sleeve 10 is in a slightly tight fit. Depending on the state, at this point, the outer sleeve 10 can be properly positioned without any shaking or up and down displacement due to liquid delivery. And when the external force of the suction pipe 20 disappears, the suction pipe 20 can be stretched out relatively by virtue of the recovery elasticity of the telescopic coiled tube 30 itself to return to the state as shown in FIG. 3 .

As shown in Fig. 4, the combined telescopic straw of the present invention can be squeezed and packaged between the tank body 70 and the screw cap 71 directly through high-temperature sterilization. The adjacent annular parts are only compressed, so there is no problem of interlocking and hindering elasticity, and when the screw cap 71 is taken out (as shown in Figure 5), the suction pipe 20 can be stretched by the elastic expansion of the aforementioned telescopic coil 30. Automatically protruding outwards, so as to provide the effect of being convenient to absorb the internal beverage. In the same way, the utility model can be used in the tank body of the pop-top can shown in FIG. 6 .

Referring to the above-mentioned state in which the suction pipe 20 is extended as shown in FIG. In terms of location, the utility model overcomes the shortcomings of the existing telescopic straws due to the high opening position resulting in air leakage and poor airtight effect, and the combined telescopic straw provides better sucking effect.

Advantage and effect of the present utility model are:

As shown in Fig. 4, under the compressed state of the telescopic suction tube, the outer diameter of the telescopic coil 30 is slightly expanded to obtain a better abutting position with the outer tube 10, which can further solve the problem of the arbitrary positioning of the outer tube 10 during transportation. The problem of shaking or shifting up and down can also achieve the effect of properly positioning the outer sleeve 10 . Obviously, the invention of this utility model is not only different from the products of the prior art in terms of structure, but more importantly, because of its ingenious design, it is especially equipped with a telescopic snake tube, which is elastic and closed, and not only provides a smooth sucking effect ; It also has a good airtight and air-tight effect, so that the outer sleeve can obtain proper positioning without any fastening steps. In addition, the utility model can adopt acid and alkali resistant materials, which has the advantage of durable preservation.

Example:

Please refer to Fig. 4 and Fig. 5 for a plan view of the first embodiment of the present utility model, wherein as shown in Fig. 4, the combined telescopic suction pipe is sealed in the liquid tank, and the telescopic suction pipe is in a compressed state at this moment. Figure 5 shows that after opening the bottle cap, the straw part will automatically pop out of the bottle mouth, that is, it can be used for sucking. The structure and mutual configuration of the combined telescopic straw are described in the design plan:

See Fig. 1, the three-dimensional system exploded view of suction pipe, and 10 in this figure is outer sleeve; As shown in Figure 1, the utility model combined telescopic suction pipe is made up of suction pipe 20; Wherein, the suction pipe 20 can be made of a hard PP material as a hollow straight pipe, and the telescopic coil 30 can be made of elastic PE material in the form of a plurality of continuous rings, and the top end forms a socket 31 that can fit with the end of the suction pipe 20 , and the flexible flexible tube 30 only forms openings on the top and bottom surfaces, and the peripheral position is closed, and the upper end of the outer sleeve 10 forms a tube body of a narrowing part 11, which can be used for the suction pipe 20 and the flexible flexible tube 30 by the outer sleeve 10 The bottom end is inserted and only the suction pipe 20 protrudes from the upper end, and the outer diameter of the telescopic flexible tube 30 is slightly smaller than the inner diameter of the outer sleeve 10 in a stretched state.

After the above-mentioned structural parts are combined, as shown in Figure 3, when the suction pipe 20 has not been subjected to external pressure, it is filled in the entire outer casing 10 due to the stretching elasticity of the flexible flexible tube 30 itself. When the flexible flexible tube 30 is squeezed relatively When the compression is in a compressed state, and the flexible flexible tube 30 is one-third of the length after compression, the outer ring surface of the flexible flexible tube 30 is also slightly expanded so that the inner wall surface of the outer sleeve 10 is in a slightly tight fit. Depending on the state, at this point, the outer sleeve 10 can be properly positioned without any shaking or up and down displacement due to liquid delivery. And when the external force of the suction pipe 20 disappears, the suction pipe 20 can be stretched out relatively by virtue of the recovery elasticity of the telescopic coiled tube 30 itself to return to the state as shown in FIG. 3 . Fig. 4, Fig. 5 are exactly the embodiment by above-mentioned design.

Fig. 6 is another embodiment of the combined telescopic straw used in a can.
