Preparation method of composite anti-blocking suction pipe

Abstract

The invention discloses a preparation method of a composite anti-blocking suction pipe. The preparation method comprises the following steps: step 1, preparing a main pipe (1) and an assistant pipe (2), wherein the process of preparing the assistant pipe is as follows: at least a row of vent holes (3) are formed in the pipe wall of a pipe body in the axis direction of the pipe body, a plurality of vent holes are included in each row of vent holes, and the assistant pipe is shorter than the main pipe; step 2. gluing on the outer wall of the main pipe or the assistant pipe, bonding the main pipe and the assistant pipe together side by side, enabling the lower ends of the main pipe and the assistant pipe to be flush with each other and the top end of the main pipe to be higher than that of the assistant pipe; step 3, obliquely cutting the lower sections of the main pipe and the assistant pipe bonded together to form a bevel cut. The vent holes in each row are formed at equal intervals and are distributed in the pipe wall of the assistant pipe in the axial direction of the assistant pipe. The preparation method of the composite anti-blocking suction pipe, disclosed by the invention, has the benefits that implementation is easy, the preparation is simple and convenient, and the smooth liquid suction can be effectively guaranteed by the composite anti-blocking suction pipe.

Description

technical field [0001] The invention relates to a preparation method of a composite anti-blocking straw. Background technique [0002] Existing straws are all single straws. When consumers taste boxed beverages, they first puncture the sealing layer on the top surface of the beverage with the short of straw to form a suction hole, and then extend the straw into the suction hole to absorb the beverage. [0003] Because the suction hole and the straw are often in close contact, the inside and outside of the box are not connected at the suction hole. Therefore, in the process of absorbing the beverage, as the liquid in the box decreases, the air pressure in the box decreases, forming a gap with the outside. Due to the pressure difference, it is difficult for consumers to suck the liquid in the clean box, or it is very laborious to suck the liquid. Therefore, it is necessary to design a new method of anti-blocking straw. Contents of the invention [0004] The technical proble...
