Description

Degradable and recyclable double-arranged straw for beverage packaging

Technical Field

The utility model relates to a degradable recoverable double-arranged straw for beverage packaging.

Background

In 12 months 2018, the european union passed the most stringent laws with history for disposable plastic articles: the use of disposable plastic straws, cutlery, swabs, etc. has been totally banned since 2021 and has been replaced by more environmentally friendly materials. To comply with the global "plastic restriction" hot tide, companies like food and beverage jumbo, mcdonald, starbucks, dirigious, paulika, etc., have successively committed to gradually stop the use of disposable plastic straws and have begun to attempt to use paper straws. However, when the disposable plastic straw is in contact with liquid drinks, the paper straw is inevitably subjected to the phenomena of damp bending deformation, adhesion of the inner wall of the straw, insufficient suction force, even dissolution and the like, so that the user experience and the use safety cause strong reverberation of consumers, and even more than 50 thousands of people have been willing to use the disposable plastic straw again. The disposable plastic straw which cannot be naturally degraded is banned, so that the sensory experience of consumers is improved, merchants or consumers are promoted to actively purchase and use environment-friendly products, and the plastic straw is a necessary condition for environmental protection problem to enter virtuous circle.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims at solving the problems of deformation, adhesion of the inner wall of the pipe, insufficient suction and even dissolution of the environment-friendly paper straw when the contact time with the liquid drink is longer, and providing a degradable recoverable double-arrangement straw for drink packaging.

The utility model discloses a realize through following technical characteristic: a degradable and recyclable double-position straw for beverage packaging comprises a silica gel plug, an external straw chute, an external straw, an internal straw guide shaft, an internal straw and a valve sample port, wherein the silica gel plug comprises a soft plug and a cover film, the soft plug is in sealing fit with the external straw, the external straw is sleeved with the internal straw, and the external straw chute and the internal straw guide shaft realize relative movement; the built-in suction pipe is fixedly arranged at one corner inside the drink package, the upper port of the built-in suction pipe is open, and the lower port of the built-in suction pipe is valve-shaped and is close to the bottom of the drink package; the beverage packaging device is characterized in that an arc-shaped limiting groove is formed in the upper portion of the beverage package, one end of the arc-shaped limiting groove is arc-shaped and tangent to the outer edge of the cover film, and the other end of the arc-shaped limiting groove is fixed to the side face of the beverage package in a folding mode.

Further, the protruding part of the first half cover film on the silica gel plug is internally tangent to the arc end of the arc limiting groove, the curvature radius of the protruding part is smaller than that of the arc limiting groove, the lower half soft plug is in interference fit with the external suction pipe, and the silica gel plug is flush with the upper surface of the arc limiting groove.

The internal suction pipe and the external suction pipe are both of a structure with a thick upper part and a thin lower part. The arc radius of the guide shaft of the built-in suction pipe is gradually increased from bottom to top, and the radius of the sliding groove of the external suction pipe sliding groove is uniform and slightly smaller than the maximum value of the radius of the guide shaft of the built-in suction pipe.

The lower port of the valve sample of the built-in suction pipe adopts a four-piece structure, and the central polymerization part is a four-cusp valve sample hole.

The arc-shaped limiting groove can be turned over and opened to form a filling opening, and can be folded into a triangle to be sealed and fixed on the side surface of the beverage package when being sealed.

The whole recoverable silica gel material that adopts of silica gel stopper, external straw adopt degradable paper, and degradable polylactic acid drenches membrane paper is all adopted with the drink package to built-in straw.

A degradable recoverable double suction pipe for beverage package, its application method lies in:

during pouring, the arc-shaped limiting groove is turned over and opened to form a large pouring opening, the upper portion of the pouring opening is in flow speed contrast with the upper end opening of the sealed straw through air flow, the pressure intensity of the pouring opening is reduced, pressure difference is formed to enable the heights of the inner liquid surface and the outer liquid surface of the straw to be different, liquid is prevented from infiltrating the external straw, and one-way outflow of the liquid in the straw is guaranteed through the valve-shaped port at the lower end of the straw.

When the sliding chute slides upwards to the position with the same arc radius of the guide shaft, the built-in suction pipe and the external suction pipe are in a clamping state, the silica gel plug is pulled out, the valve port is opened inwards, liquid in the box enters the suction pipe, and the inner liquid and the outer liquid are same in plane and can be drunk.

Compared with the prior art, the utility model the advantage lie in: (1) the built-in suction pipe is integrated with the beverage packaging structure, so that the raw material and processing cost can be effectively reduced, and the problems of bending deformation and inner wall adhesion of the paper suction pipe after the paper suction pipe is contacted with the beverage liquid for a long time are avoided; (2) the inner and outer suction pipes are both of a structure with thick upper parts and thin lower parts, so that the liquid can be sucked more quickly and massively under a certain pressure, and the problems of insufficient suction and dissolution of the paper suction pipe caused by long-time contact during drinking are effectively solved; (3) the external straw and the liquid can be always separated by controlling the air flow of the perfusion environment during the non-drinking period, the unnecessary contact time of the paper external straw and the liquid is obviously reduced, and the problem that the paper straw is dissolved during the non-drinking period is solved; (4) the arc radius of the guide shaft of the built-in suction pipe is gradually increased from bottom to top, the diameter of the sliding chute of the built-in suction pipe is uniform and slightly smaller than the maximum radius value of the guide shaft of the built-in suction pipe, and the sliding chute of the built-in suction pipe is blocked at the same radius position while generating relative sliding, so that the pulling-out and fixing of the built-in suction pipe and the pulling-out of the silica gel plug can be simultaneously completed, the use of a consumer is facilitated, and the problem that the suction pipe; (5) the internal and external straw sleeves are embedded and fixed inside the beverage package, so that the straw is prevented from being lost, and the cost and the environmental burden are increased without independent packaging; (6) the lower port of the valve sample adopts a four-piece structure, and the central polymerization part is a four-cusp sample hole, so that the one-way rapid circulation of liquid during the filling and drinking periods is effectively ensured; (7) the built-in straw and the beverage package all adopt degradable polylactic acid to drench membrane paper, and external straw adopts degradable paper, and the silica gel stopper adopts recoverable silica gel material, has realized the green circulation of whole materials and is convenient for categorised the recovery.
