Description

A kind of preparation method of composite anti-blocking straw

technical field

The invention relates to a preparation method of a composite anti-blocking straw.

Background technique

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.

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

The technical problem to be solved by the present invention is to provide a method for preparing a composite anti-blocking straw, which is easy to implement and easy to prepare, and can ensure smooth liquid absorption.

The technical solution of the invention is as follows:

A kind of preparation method of composite anti-blocking straw, is characterized in that, comprises the following steps:

Step 1: prepare the main pipe (1) and the auxiliary pipe (2);

The process of preparing the secondary pipe is: opening at least one row of vent holes (3) under the pipe wall of the pipe body along the axial direction of the pipe body; each row of vent holes includes a plurality of vent holes; the length of the secondary pipe is smaller than the length of the main pipe;

Step 2: Apply glue on the outer wall of the main pipe or the auxiliary pipe, and glue the main pipe and the auxiliary pipe side by side; and the lower ends of the main pipe and the auxiliary pipe are flush, and the top of the main pipe is higher than the top of the auxiliary pipe.

The preparation method of the composite anti-blocking straw also includes step 3: cutting the lower section of the bonded main pipe and auxiliary pipe obliquely to form an oblique incision.

A plurality of ventilation holes in each row of ventilation holes are arranged at equal intervals, and spread all over the tube wall of the secondary tube along the axial direction of the secondary tube.

The air holes are arranged in 2 rows symmetrically with respect to the axis of the secondary pipe. [In this way, when bonding the main pipe and the auxiliary pipe, it can be guaranteed that all the two sets of holes will not be blocked]

The inner diameter of the auxiliary pipe is smaller than or equal to the inner diameter of the main pipe.

The inner diameter of the auxiliary pipe is 1/2 or 1/3 of the inner diameter of the main pipe.

In the preparation process of the auxiliary pipe, first prepare a pipe body without vent holes on the outer wall, then use a puncher to punch holes at equal intervals on the pipe body, and then cut the pipe body into multiple sections, each section is the said auxiliary pipe . This is a method with high efficiency and high degree of automation. The preparation of the pipe body, drilling and cutting are all completed by machinery and assembly line. The main pipe is also prepared by first preparing the pipe body and then cutting it into multiple sections.

The upper end of the auxiliary pipe is sealed to prevent dust from falling in.

Beneficial effect:

The preparation method of the composite anti-blocking suction pipe of the present invention adopts very simple steps, and the preparation of the main pipe and the auxiliary pipe and the oblique incision at the bottom end can be implemented in an automated and mechanized manner, and the efficiency is high.

It is preferable to adopt two rows of ventilation holes, and only one perforation can form two rows of perforations, which is easy to implement.

In addition, the composite anti-blocking straw uses the auxiliary pipe with multiple ventilation holes to make the inside and outside of the box guide the air when using this straw to suck the beverage in the box, avoiding the pressure difference between the inside and outside of the box, thus making it possible to absorb liquid smoother.

The ventilation holes are evenly arranged, beautiful in shape, and spread all over the pipe wall of the secondary pipe along the axial direction of the secondary pipe, in order to ensure that not all the holes are blocked by the liquid in the box, and to facilitate the mass production of the ventilation holes on the secondary pipe.

The length of the main pipe is greater than the length of the auxiliary pipe; and the top of the main pipe is higher than the top of the auxiliary pipe, which is convenient for the user to suck the drink. Otherwise, if the upper ends of the main pipe and the auxiliary pipe are flush, it is easy to inhale some air when drinking the drink.

Diagonal cuts at the bottom of the primary and secondary tubes allow the bottom of the compound anti-block straw to form a sharp end for puncturing the seal of the boxed drink.

All in all, the preparation method of the composite anti-blocking straw is ingeniously conceived, and the prepared composite anti-blocking straw can provide great convenience for consumers of boxed beverages.

Detailed ways

The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment:

Embodiment 1: As shown in Fig. 1-4, a kind of preparation method of composite anti-blocking straw, is characterized in that, comprises the following steps:

The process of preparing the auxiliary pipe is: opening at least one row of ventilation holes 3 along the axis direction of the pipe body under the pipe wall of the pipe body; each row of ventilation holes includes a plurality of ventilation holes; the length of the auxiliary pipe is smaller than the length of the main pipe;

Step 2: Apply glue on the outer wall of the main pipe or the auxiliary pipe, and glue the main pipe and the auxiliary pipe side by side; and the lower ends of the main pipe and the auxiliary pipe are flush, and the top of the main pipe is higher than the top of the auxiliary pipe;

Step 3: Cut off the lower section of the bonded main pipe and auxiliary pipe obliquely to form an oblique incision.

A plurality of ventilation holes in each row of ventilation holes are arranged at equal intervals, and spread all over the tube wall of the secondary tube along the axial direction of the secondary tube.

The air holes are arranged in 2 rows symmetrically with respect to the axis of the secondary pipe. In this way, when the main pipe and the auxiliary pipe are bonded, it can be guaranteed that the two groups of holes will not be completely blocked, and only one perforation can form two rows of perforations, which is easy to implement.

The inner diameter of the auxiliary pipe is smaller than or equal to the inner diameter of the main pipe.
