Description

Novel suction tube

Technical Field

The utility model relates to a food package field especially relates to a novel straw that can inhale milk tea and pearl in step.

Background

At present, the daily consumption of milk tea in China is 4 cups, and the data of various cities such as Beijing, Shanghai, Hangzhou and the like are displayed as 30 cups. However, compared with the number of 150 cups consumed in Taiwan and hong Kong, the milk tea market in China still has wide space. The use of a proper straw is not only elegant, but also provides a convenient, comfortable and safe feeling for the drinker. Therefore, the problem that the existing straw is unsatisfactory is solved, and the magic pearl milk tea straw has great market potential and brings greater economic benefits for merchants.

Chinese patent No. CN201160735, a straw, discloses a straw, which comprises a tube body; the tube body is a hollow cylinder and is provided with an outer surface, two ends and a plurality of spacing parts, and the spacing parts are formed on the outer surface at intervals and extend from one end to the other end of the tube body; several embedded layers extending from one end to the other end of the pipe body and having two side edges, wherein the side edges are respectively connected with one side of a spacing part, so that the embedded layers and the spacing part are arranged on the outer surface of the pipe body at intervals, and the arc length of the radial surface of the embedded layers is not less than that of the spacing part. The patent can only be diversified in appearance and can attract people and stimulate the desire of eating of users.

However, the suction tubes in the prior art have the defects that the milk tea is completely drunk and a large amount of pearls are left at the bottom of the cup.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a novel straw that can inhale milk tea and pearl in step. The novel suction pipe comprises a straight pipe part and a funnel part; the inner diameter of the funnel part is increased from the narrow-mouth end to the wide-mouth end;

The following briefly describes the usage and performance of the novel straw of the present invention.

In an embodiment, will the utility model discloses a novel straw inserts the multi-functional bowl cover of buckle closure type (common bowl cover that is on the bowl cover on the market simultaneously has the milky tea round hole and the little flat hole of coffee), contains pearl milky tea in the cup, siphons away partial air to the port of straight tube portion 1, will cause intraductal pressure to diminish, and for balanced atmospheric pressure, atmospheric pressure will force intraductal liquid and pearl to rise. When the suction stops, the liquid in the tube drops and the pressure returns to equilibrium. There are a plurality of little triangle-shaped breachs wide-mouth end 2.2 below, can avoid straw and bottom of cup airtight too tight, lead to the outside liquid of funnel portion to flow in, cause the interior vacuum of straw, influence the convenient degree of sucking.

Comparative experiments were carried out using the novel pipettes of examples 1-4 with a commercially available cylindrical pipette having an internal diameter of 1.1 cm. The specific experimental methods and results are as follows:

1. making pearl milk tea

Actual measurement of 6 well-known pearl milk tea on the market, as shown in fig. 2 and 3, a cup of 590 ml of Huang crown Huang tea contains 51 pearls (11.57 ml of milk tea per pearl on average); while a cup of 390 ml nanyang tea shop milk tea contains 150 pearls (average 2.6 ml per pearl milk tea). Comprehensively considering: the total liquid portion of six cups of milk tea is 3030 ml, the total number of pearls is 823, and the average corresponding proportion is 3030 ÷ 823 ═ 3.68 (ml/granule)

According to the proportion of milk tea on the market, the milk tea with 5 cups and 600ml is prepared, and each 28-30ml of milk tea with 8 pearls (the diameter is 0.9 cm) (hereinafter referred to as experimental milk tea).

2. The 4 suction tubes of examples 1-4 and one suction tube of the prior art are adopted to respectively suck a cup of experimental milk tea, the number of the pearls remained after all the milk tea is sucked is counted, and the result is as follows: the pipette of example 1 left 5 pearls last, the pipette of example 2 left 6 pearls last, the pipette of example 3 left 5 pearls last, the pipette of example 4 left 4 pearls last, and the pipette of the prior art left 20 pearls last. Thus, using the 4 straws of examples 1-4, the number of remaining bottoms of pearls was significantly less than the prior art straws.

Performance testing of the pipette of example 4

1. Area checking

The projected area of a pearl with a diameter of 0.9cm is: pi r²＝3.14×0.45×0.45＝0.64cm²。

The funnel part 2 is a round table structure which is continuously narrowed, so that the diameter of a circle with the height of 0.9cm is 2.64 cm, and the area of the circle is pi R²＝3.14×1.32×1.32＝5.47cm²(ii) a Then 5.47cm²/0.64cm²That is, the straw of example 4 may be used as 8.5 piecesSo as to simultaneously cover 8.5 pearls (the whole is 8) with the diameter of 0.9 cm.

2. And (3) volume checking calculation:

1. the pipette of example 4, wherein the straight tube part 1 having an internal diameter of 1.1cm and a height of 20.5cm can hold a liquid of π r²H＝3.14×0.55×0.55×20.5＝19.47ml；

2. In the straw of example 4, the narrow end 2.1 of the funnel part 2 has a diameter of 1.1cm, the wide end 2.2 has a diameter of 3.5cm and a height of 2.5 cm. 1/3 pi h (R) is obtained according to the volume calculation formula of the circular truncated cone²+r²+R×r)＝1/3×3.14×2.5×(1.75×1.75+0.55×0.55+1.75×0.55)＝11.32ml；

3. The volume occupied by 8 pearls covered by the funnel part 2 is 8 multiplied by 4/3 pi r³＝8×4/3×3.14×0.45×0.45×0.45＝3.05ml。

The volume of liquid after 8 pearls of 0.9cm diameter are sucked up by the pipette of example 4 is about 28 ml.

The amount of milk tea drunk by adults is 28-30ml, and according to the analysis, the straw in the embodiment 4 can suck 8 pearls with 28-30ml milk tea per mouth, and finally, the milk tea and the pearls are almost consumed at the same time.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
