Description

Cup with straw

Technical Field

The utility model relates to daily necessities, in particular to a cup for containing beverage.

Background

The yoghourt is popular among people as a delicious and nutrient beverage. However, many packages in the market are not suitable due to the sticky property of the yogurt, and a large amount of yogurt often remains after drinking the yogurt, which becomes a trouble for most consumers: if only a common straw is relied on, the yoghourt is always remained on the cup wall and the cup bottom and can not be removed cleanly; yogurt on the cup lid is also often overlooked as the lid is dropped into the trash can. These situations are very common and this annoyance is experienced by many people around us. The residual yogurt not only causes a great deal of waste, but also affects sanitation (for example, the residual yogurt in the cup smells in hot days).

In addition, the straw can be quickly drunk by people to serve yoghourt, but wall-hanging yoghourt always exists on dead corners of the package, and the straw cannot be cleanly removed, so that a large amount of waste is caused. Although the spoon can scrape off part of the wall hanging, the time for using the spoon is long, and the drinking speed is influenced. In addition, the hydrophobic property of the existing straw is not obvious, so that the yoghourt or other beverages on the straw cannot smoothly and quickly slide down, and certain improvement needs to be carried out on the material of the straw.

Therefore, there is a strong need in the art to develop an innovative package that allows consumers to enjoy the delicateness of food while enjoying the convenience of a humanized package, while avoiding waste of beverage and environmental pollution by improving the structure of the straw.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a convenient yoghourt cup which is convenient for yoghourt without hanging on a wall, so that the food waste is reduced, and consumers can enjoy the convenience brought by humanized packaging while enjoying delicious food.

The utility model provides a cup with a straw, which comprises a straw 1, a cup body 2 and a cup cover 4, wherein one end of the straw 1 extends out of the cup cover 4, the other end of the straw 1 extends into the bottom of the cup body, and one end of the straw 1 on the cup cover 4 is detachably fixed with a button 3; the cup cover 4 is provided with a through hole, the straw 1 penetrates through the through hole, and the button 3 can drive the straw 1 to rotate.

A plurality of bulges are arranged on the outer side of one end of the straw 1, and pits corresponding to the bulges are arranged on the inner side of the button 3, so that one end of the straw 1 is clamped with the button 3; the button 3 can drive the straw 1 to rotate along the inner side of the cup body.

The cup bottom comprises a cup bottom outer layer 22 and a cup bottom inner layer 21, wherein the cup bottom outer layer 22 is a plane, and the cup bottom inner layer is a part of a spherical surface.

The curve of each cross section of the cup bottom inner layer 21 is the fastest curve.

The cup is characterized in that the suction pipe 1 comprises a suction pipe main body provided with a plurality of joints 13, the suction pipe main body is made of polypropylene plastics, the surface of the suction pipe main body is provided with an etched micro-nano structure, and the micro-nano structure is covered with a hydrophobic coating.

The hydrophobic coating is a mixed wax coating of palm wax and beeswax.

The joint 13 is arranged at 3-5 positions on the sucker body, and the joint 13 can freely adjust the bending degree of the sucker body, so that the sucker body is attached to the cup cover and the cup body of the cup.

The joint 13 has a bellows structure.

The opening of one end 12 in the cup body of the straw main body is an inclined opening.

In the cup, the cup cover part attached to the sucker body is provided with a plurality of broken line-shaped tearing lines 41 formed by cutting off point cuts along the outer edge of the sucker.

The cup is a yogurt cup.

The outer part of the cup is in a square column shape, a cylinder shape or a rectangular column shape. Preferably, the cup is cylindrical.

The yoghourt package or the cup is designed into a cylinder shape, the base of the cup is hollow, the outer layer of the cup is round and is a plane, and the stability of the cup is guaranteed. And the inner layer of the bottom of the cup is replaced by a curved surface taking the fastest curve as a generatrix, so that the yoghourt is expected to slide down more quickly. The steepest curve is the locus of any point on the circumference of a circle when the circle is rolled along a straight line (no slip). The shape of the fastest curve is a curve, the initial speed is nearly vertical acceleration, the object obtains the capability of rapidly passing the horizontal displacement of the second half, and the average speed is fastest. Suppose that the radius of the circle determining the steepest curve is r_2，The radius of the cross section of the bottom of the cylindrical cup is r, which determines the circumference of the circle of the steepest curve (i.e. 2 Π r as shown in FIG. 2)₂) The steepest curve, i.e. radius r, is the diameter of the cup bottom (i.e. 2r as shown in figure 2)₂The locus of any point of the circle of (a). A knob is newly added in the center of the cup cover, and a polypropylene suction pipe is clamped in the knob. The straw is attached to the curve of the cup body, and can scrape off the yoghourt on the cup wall, the cup bottom and the cup cover by rotating the knob. By imitating the hydrophobic surface of lotus leaf which can 'self-clean', the micro-nano structure array is etched on the surface of the suction pipe, and then the micro-nano structure array is placedHydrophobicity of large polypropylene. A plurality of dotted tearing lines formed by cutting points are arranged in the yoghourt cup cover, and the cup cover can be easily torn off only by pinching the knob and straightening the straw upwards. Then the blocked straw is pulled out from the knob to drink the yoghourt.

Through the design, the problem of wall hanging of the yoghourt can be effectively solved, waste is reduced, and the yoghourt can be more conveniently drunk.

The utility model also adopts a straw with higher hydrophobic performance and a plurality of adjustable curvatures.

The thickness of the mixed wax coating is 10-300 microns, and about 20-100 microns is optimal.

In order to save space and reduce the residual rate of the yoghourt, the yoghourt cup is designed into a cylindrical shape by the inventor. In order to make the yoghourt flow more quickly and smoothly, the element of the fastest curve is added into the cup body. The steepest curve is also called steepest descent line and is a curve. The swiss mathematician Johann Bernoulli has first demonstrated that on a curve, an object can move with the fastest speed from one fixed point to another point not vertically below it under the influence of gravity. This was subsequently confirmed by members of the newton, lebeniz and bernoulli families. The line is added when the cup body is designed, so that the flow of liquid in the cup can be accelerated.

The inventor has made an improvement over the original flat cup bottom, using a steepest curve to construct the cup bottom. The curve starts to accelerate approximately vertically, so that the object can rapidly pass through the horizontal displacement in the second half, and the average speed is fastest. Assuming that the radius of the circle determining the steepest curve is r_2，The radius of the cross section of the bottom of the cylindrical cup is r, which determines the circumference of the circle of the steepest curve (i.e. 2 Π r as shown in FIG. 2)₂) The steepest curve, i.e. radius r, is the diameter of the cup bottom (i.e. 2r as shown in figure 2)₂The locus of any point of the circle of (a). Calculated, radius r of the circle of the steepest curve₂The radius r/pi of the cup bottom is determined, and the radius r of the circle of the steepest curve can be obtained by confirming the diameter of the cup bottom₂This curve can then be drawn.

Note that: since r participates in the calculation of pi, an accurate value cannot be obtained, and the r is close to pi as much as possible in the calculation.

The straw can let the people drink the acidophilus milk fast, can always have the wall built-up acidophilus milk on the dead angle of packing, and the straw can't be got rid of cleanly, can cause a large amount of wastes. Although the spoon can scrape off part of the wall hanging, the time for using the spoon is long, and the drinking speed is influenced. In order to reduce the cost and the use time of the user, the inventor chooses to innovate the straw at the same time.

The straw is firmer and harder than the common yoghourt straw, and one end of the straw is clamped in the knob at the center of the cup cover and can rotate along with the rotation of the knob. The straw has three joints that can twist, can be fixed, and the curve of laminating wall of cup and bowl cover can scrape the remaining acidophilus milk of wall of cup, bottom of cup and bowl cover along with rotatory knob. In addition, the yoghourt cup cover is also provided with a dotted line, the cup cover can be easily opened along the dotted line, so that after the yoghourt is scraped, the cup cover can be opened along the texture as long as the knob is pinched and pulled up by hands. Before drinking, the exposed part of the straw is adjusted, and the knob buckled on the straw is pulled off.

After scraping off the yogurt on the cup wall, a lot of yogurt remains on the straw. The straw is made of a common polypropylene plastic (non-toxic) as a yogurt cup, and although the surface energy is low (the excess energy of the surface particles relative to the internal particles), the hydrophobic properties are not significant. Therefore, in order to make the yogurt on the straw slide down smoothly and quickly, certain improvement needs to be made on the material of the straw.

1. Improvements in or relating to

Micro-nano etching is firstly carried out on the surface of the suction pipe, and the hydrophobicity of the polypropylene is amplified.

Secondly, spraying a special hydrophobic coating on the surface of the suction pipe. Since the straw is in direct contact with the food, the classic hydrophobic coating contains fluorine, is toxic and is not suitable for use. According to the research of scientists, wax acetone emulsion (acetone smell causes discomfort, but is nontoxic and can be volatilized) can be prepared by using palm wax and beeswax, and the yoghourt can not stick to a straw and can slide off more quickly and smoothly after the coating is sprayed on the straw.

2. Principle of

The surface of the solid is rough and uneven (no completely smooth surface exists), and when the liquid meets the solid with weak hydrophobicity, grooves which can fill the surface of the solid are formed, so that the direct solid-liquid contact is formed, and the Wenzel state is called. However, when the surface of a solid is more hydrophobic, the surface is not filled with liquid alone, but a gas cushion is formed between the solid and the liquid, which causes the solid-liquid contact to become a solid-gas-liquid contact, called a "Cassie state". Under the Cassie state, the air cushion holds up the liquid and can amplify the hydrophilicity and the hydrophobicity of the solid surface. The etching of the micro-nano structure can construct a Cassie state on the surface of the suction pipe, form an air cushion and amplify the hydrophobicity of the polypropylene plastic.

The wax acetone emulsion prepared from palm wax and beeswax is sprayed on the surface of a solid according to a specific pressure, so that a layer of low-surface-energy substance can be formed, the hydrophobicity of polypropylene plastic is enlarged, the polypropylene plastic is combined with a micro-nano structure, the contact angle between liquid and the solid is reduced, and the required effect is achieved. Experiments by researchers at the Colorado State University, CSU for short, have shown the reliability of this method in detail in the paper Superhydrophic Coatings with electronic Materials (Wei Wang, Karsten Lockwood, Lewis M. Boyd, Matthew D. Davidson, Sanli Movafaghi, Hamed Vahabi, Salman R. Khetani, and arc K. Kota-2016.7.12).

In conclusion, the problem that drinks such as yoghourt are stuck on a straw can be effectively solved by combining the etching of the micro-nano structure and the spraying of the wax acetone emulsion. In addition, a plurality of joints are arranged, such as the bellows part, the straw body can be bent and rotated in different directions, so that the straw is not easy to slide off the container, and in addition, the straw can be suitable for different shapes of the container and is attached to the inner wall of the container.
