Description

TECHNICAL FIELD OF THE DISCLOSURE

This embodiment relates in general to straws for drinks. More specifically, the preferred embodiment relates to straws that can be opened up or unfolded for wash after use and then closed for reuse.

BACKGROUND OF THE INVENTION

Straws are used in everyday life for the purpose of sucking up liquid, such as water and drinks. Due to the large use of disposable plastic straws in modern life, resulting in increasingly serious environmental problems and health problems, has aroused high concern and attention of all sectors of the society.

The invention of this straw (also refers as the pipette) is designed to turn the straw into one of reusable tableware, thereby reducing or even avoiding the use of disposable plastic straws, reducing their negative impact on the environment and health, and improving people's lives. Reducing the amount of disposable plastic straws is one of the most effective ways to reduce the damage of plastic waste to the nature.

To solve the problem of cleaning and disinfecting the inside of the straw when the straw is reused, it becomes safe tableware that can be handled in the dishwasher or other automated cleaning and disinfection equipment.

When the straw is no longer a fast-moving consumer goods (FMCG), but a reusable tableware, we have the condition to adopt a more durable and human health-friendly material, to solve the industrial residues caused by disposable plastic straws and the harmful effects of chemical substances on human health in the event of heat.

It is documented that the first known modern straws for drinking purposes were made by the Sumerians several thousand years ago. The earlier straws were made of gold. They were used for drinking beer in order to avoid the solid byproducts of fermentation that sink to the bottom. The rye grass straws were used in 1800s because they were cheap and soft, but they had tendency to turn to mush in liquid. The wax paper straws were patented in 1888 to avoid the rye grass straws' problems.

Straw is the use of the principle of atmospheric pressure. Using the suction of the air in the inner part of the straw resulting in a small tube pressure. In order to balance the pressure, the pressure outside the tube forcing liquid pressure into the suction tube. This results in the liquid surface rise. Continuing to suck the straw, one can make the liquid to rise continuously and achieve the drinking purpose.

Assuming that the power of the sucking straw can be infinitely large, the height of the liquid level in the straw tube is determined by the strength of the tube wall. Assuming that the strength of the pipe wall can be infinite, then the height limit of the liquid level rise in the pipe is the level at which the atmospheric pressure can be pressed out. A standard atmospheric pressure, the height limit of mercury rise is 76 cm and the height limit of water rise is about 1033.6 cm. The above laws are assumed to be good air tightness of the pipe wall, non-leakage of the case Occurs. Since the length of the drink straw used in daily life is only between 10 cm to 40 cm, the height of the liquid level in the tube that the sucking beverage needs to reach is much lower than the above limit value. Therefore, the pipe wall does not need high air tightness requirement. In fact, after experiment, even if we in a 20 cm long diameter of 5 mm beverage straw above the level of the water cup two 1 mm diameter holes, still do not affect the use of straws. We can use A straw to drink water, and suck the drink when inhaled some bubbles. It is shown that the beverage straw is not high in air tightness. So long as it can improve the processing precision of the pipe wall of the tube, even if the pipe wall of the tube has a connecting seam, it can be used as the existing seamless straw.

Design a beverage straw that can be unfolded, re-used again, and easy to clean inside. The main issue is to solve two problems. First of all, since the straw is designed to be opened up or unfolded to clean and disinfect the internal structure. A method needs to be used to allow the straw to be reassembled into a tubular form, and solving the connection problem from “flat” or “curved” re-assembled into a “tubular” form. This design needs to be simple, effective, easy to manufacture and easy to use. This part of the design is call “Folding and Reassemble Design.” Secondly, choose durable and environmentally friendly materials to manufacture the straws. This part of design is called “material selection.”

Because of the protection of environment and creation of a durable tableware, use the “Folding and Reassemble Design” of the straw as a novel straw design is the key of the invention described in this patent application.

SUMMARY OF THE INVENTION

The invention has several different embodiments to achieve the goal of having the Folding and Reassemble Design of the straws.

The invention has several embodiments to achieve the goal of having a washable and reusable straw. The straw is made of any semi-rigid materials. The straw material needs to tolerate a relatively high temperature, such as steam temperature, in order for high-enough temperature to disinfect the straw after it is washed. The straw material needs also to be flexible enough to be opened at the connective joint or hinge of the straw.

A typical embodiment of the invention is a straw with an elongated tube body, a closeable opening, and a pair of tabs. The opening is along the longitudinal wall of the straw. The opening has two edges along the opening. The straw can be closed by pushing the tabs along with the edges of the opening toward each other. The tabs are affixed on the edges of the opening with one tab on each edge. Each tab is affixed to a position on one edge slightly different from the other tab's affixed position. This positioning scheme is to ensure an easy separation of the tabs, thereby separating the edges of the opening from each other. The tabs can have variety of different shapes such as square, rectangle, triangle, etc.

The straw wall has a predetermined thickness. Depending upon the size of the straw, the thickness of the wall can be in a range approximately from 0.5 mm to 4 mm.

A straw has a connective joint, an interlock mechanism at the edges of the opening, and another interlock mechanism close to the connective joint. The connective joint can also be called as a hinge. The connective joint connects two half straw together when the straw is in an opened state. The thickness of the straw wall at the connective joint is thinner than the rest of the straw wall, so that the straw can be easily opened and closed. The connective joint can have many different designs.

The interlock mechanism is designed to seal the opening. The interlock mechanism is along the edges of the opening. The interlock mechanism can be two notched members matching to each other to seal the edge of the opening by snapping the two notched members together.
