Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.

The present embodiment relates to a disposable pipette, as shown in fig. 1 and 2, comprising: support frame 1, flexible outer tube 2 and connecting piece. Wherein, support frame 1 sets up in flexible outer tube 2, and support frame 1 is used for strengthening the intensity of flexible outer tube 2 to avoid the condition of warping in the liquid because straw intensity is not enough. The flexible outer pipe 2 is fixed at the head end and the tail end of the support frame 1 through connecting pieces, the flexible outer pipe 2 is made of metal foils, the metal foils are wound along the periphery of the support frame 1, and the parts of the metal foils, which are in contact with each other, are fixed through the connecting pieces.

In the embodiment, the flexible outer tube 2 is formed by winding a sheet metal foil around the periphery of the support frame 1 by one circle, the contact parts are connected by a connecting piece, and the connecting piece is a food-grade glue coating. Preferably, the metal foil is a stainless steel foil, and the material of the support frame 1 is the same as that of the metal foil, so as to facilitate recycling. It should be noted that, under the condition of ensuring the strength of the disposable straw, the distance between the coils on the support frame 1 is set as large as possible, so as to reduce the weight and save the production cost. In other embodiments, the flexible outer tube 2 is formed by winding a sheet metal foil around the support frame 1 for more than one turn; the metal foil can also be in a band shape, and the band-shaped metal foil is wound for a plurality of circles along the periphery of the support frame to form a flexible outer tube 2; the metal foil can also be aluminum or other food-grade antirust metals.

As shown in fig. 1 and 3, the flexible outer tube 2 is provided with a folded portion 3, and the folded portion 3 is used for extending along the axial direction to prolong the disposable pipette. The support frame 1 is set to be in a spring shape, and the coils corresponding to the folding parts 3 on the support frame 1 are densely arranged, so that the flexible outer tube 2 can be conveniently stretched or bent. In this embodiment, the supporting frame 1 is a spring formed by a spiral cylindrical metal strip, the end of the cylindrical metal strip extends to the side far away from the sucking end and then is folded back and welded to the inner ring of the spring to form a V-shaped reinforcing rib 4, and the reinforcing rib 4 is used for reinforcing the strength of the supporting frame so as to facilitate the insertion of the disposable straw into the beverage box. In other embodiments, the support frame 1 is formed by spirally forming a hollow cylindrical, square or flat through metal strip, when the support frame 1 is formed by spirally forming the square metal strip, the contact area between the disposable suction tube wall and the hot drink suction tube is increased, the heat dissipation of the hot drink is facilitated, and the risk of burning the mouth of a user is reduced to a certain extent.

The sucking end of the disposable straw is provided with a smooth part 5, and the smooth part 5 is used for preventing a user from being accidentally cut by the flexible outer tube 2 when sucking. Preferably, the smooth part 5 is a part of the flexible outer tube 2 which is folded towards the inner ring of the support frame 1 near the sucking end and then fixed by a fixing piece. One end of the flexible outer tube 2, which is far away from the smooth part 5, is folded towards the inner ring of the support frame 1 and then fixed on the inner wall of the support frame 1 through a fixing piece. The fixing piece is a food-grade glue coating.

The working principle of the utility model is as follows: when in use, the straw is inserted into liquid, and then the liquid can be sucked. In the use process, when the length of the suction pipe needs to be prolonged, the disposable suction pipe can be stretched from two sides of the folding part 3, so that the densely arranged parts of the spiral rings on the support frame 1 are deformed, and meanwhile, the folding part 3 is stretched, so that the length of the suction pipe is prolonged; when the straw is required to be bent, the folding part 3 is stretched and bent, and the straw has the advantages of recycling, bending and stable shape.

The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
