Description

Bendable straw

Technical Field

The utility model relates to a straw for beverage especially relates to a straw of can buckling.

Background

Liquid foods, such as milk and yogurt, and semi-liquid foods, such as fruit juices, are widely sold in small volume packaging containers. The packaging container is used to protect the food product throughout the value chain during transport and handling. The top of the small-volume liquid beverage package is generally provided with a round hole-shaped weak area, the number of layers of packaging materials in the weak area is small, the thickness of the packaging materials in the weak area is small, and a consumer can puncture the weak area by using a suction pipe to form an opening on the liquid beverage package for drinking.

With the continuous increase of the consumption of liquid beverages and the increasing production demand of straws, plastic straws widely used at present are difficult to degrade and metabolize under natural conditions, and a large amount of waste plastic straws cause heavy burden to the environment. The use of environmentally friendly degradable materials for manufacturing drinking straws has become an urgent task. At present, the produced environmental protection straw is generally a degradable paper straw or a PLA (polylactic acid) straw.

In liquid beverage packages, the drinking straw is usually individually packaged and affixed to the beverage package. For ease of use, the length of the straw is to a certain extent longer than the height of the beverage package or its diagonal. For this reason, the straw attached to the beverage package often employs a two-piece straw or a flexible straw. Due to process limitation, the paper suction pipe used in the market at present is mostly a straight pipe or two sections of straight pipes which need to be assembled by consumers before use; the PLA straw is made of starch of various plants and has good biodegradability, but the PLA straw has high brittleness and poor toughness and is difficult to be made into a bendable straw.

Detailed Description

the technical means adopted by the present invention to achieve the predetermined object will be further described below with reference to the drawings and preferred embodiments of the present invention.

Fig. 1 and fig. 2 are schematic diagrams illustrating an exploded state and a bent state of a bendable straw according to an embodiment of the present invention. The straw is sequentially provided with a first part 1, a second part 2 and a third part 3 from top to bottom in use, wherein the first part 1 is one end of the straw which is directly contacted with a consumer, the third part 3 is one end of the straw which is directly contacted with a beverage, and the second part 2 is arranged between the first part 1 and the third part 3. The first part 1 and the third part 3 of the suction tube are both straight tubes, the length of the first part 1 is smaller than the length of the third part 3, and the length ratio of the first part 1 to the third part 3 is preferably 1:3 or 1: 4. The second part 2 of the straw is a bendable pipe, the second part 2 is made of a soft structure or the second part 2 is processed, so that the bendable pipe can be bent in any direction within the range of 0-360 degrees, and the angle of the bendable pipe can be adjusted freely when a consumer uses the straw.

The first part 1, the second part 2 and the third part 3 of the straw are fixedly connected, all the parts are bonded by using an adhesive, the parts cannot move relatively after being bonded, and the adhesive is an environment-friendly nontoxic food-grade adhesive. In fig. 1, the bonding site 4 is a bonding site between the first portion 1 and the second portion 2, and the bonding site 5 is a bonding site between the second portion 2 and the third portion 3, which are not drawn to scale for clarity of illustration and generally have a thickness of not more than 1 mm. The first part 1 and the second part 2 of the straw can be integrated and then bonded with the third part 3 by adhesive; or the third part 3 and the second part 2 of the straw are integrated and then bonded with the first part 1 by using an adhesive, as long as at least one part of the components of the straw is a straight pipe, and at least one other part of the components of the straw is a bendable pipe.

The first part 1, the second part 2 and the third part 3 of the straw can be made of the same material or different materials respectively, and the materials of the parts of the straw are preferably made of food-grade degradable environment-friendly materials, such as degradable food-grade plastics, degradable food-grade rubber, degradable food-grade biological materials or degradable food-grade paper materials. For example, the third part 3 and the first part 1 of the straw are made of degradable food-grade paper materials or degradable PLA materials, different patterns or figures can be printed on the outer sides of the pipe bodies of the third part 3 and the first part 1, and the bendable pipe of the second part 2 is made of folded paper materials with a thinner thickness or other food-grade materials with higher toughness.

Fig. 3 is a schematic view illustrating a bent state of a straw according to another embodiment of the present invention. In figure 3 the second portion 2 of the drinking straw is provided with indentations 6, preferably the indentations 6 have a width of 0.5-2mm, a spacing of 1-3mm between the indentations 6 and a number of 3-15 indentations 6. The indentation 6 is typically performed on the second portion 2 using an indentation apparatus, such as an indentation on the second portion 2 made of a paper material. The pulp from which the second portion 2 is made comprises cellulose having a high freeness and long fibers, the majority of the fiber length of which is equal to or greater than 5mm, the longer fibers and high freeness allowing a higher degree of network formation, so that the paper tube made has a higher material strength while maintaining a high elasticity. The paper tube is a tubular paper tube which is formed by winding multiple layers of thin paper on a winding device, each layer is adhered to the adjacent layer, the thickness of the paper used by the paper tube is 0.05-0.45mm, the number of the layers of the paper tube is generally 3-8, and the wall thickness of the paper tube is generally 0.15-3 mm. The indentation equipment is provided with a stripe core rod and a corresponding embossing roller, the stripe core rod extends into the paper tube to drive the paper tube to rotate around the axis of the paper tube, and the embossing roller is pressed into the surface of the paper tube from top to bottom to form an indentation on the surface of the paper tube. In order to be able to produce different types of flexible paper tubes with the same device, the marking device is provided with replaceable strip mandrels and embossing rollers with different strip numbers, intervals and depths. The indentation is generally carried out before the paper tube is dried, and the paper tube still keeps high residual humidity, so that the tube body does not become hard and brittle, and the indentation is easily formed on the paper tube. In fig. 3, the first part 1 and the second part 2 of the straw are of an integral structure, and the bonding site 5 is the bonding site between the integral structure and the third part 3 of the straw.

Fig. 4 is a schematic view illustrating a usage state of a straw according to another embodiment of the present invention. In figure 4 the second portion 2 of the straw has a zigzag or wave-shaped compressed fold configuration which allows the second portion 2 to be bent or extended. The compressed folded structure of the second part 2 may be formed by moulding from degradable food grade plastics; or the paper tube after indentation is compressed and folded by the folding device, the indentation depth of the indentation which needs to be folded is generally deeper, and the indentation distance is narrower. The end of the third part 3 can be a flat head or a pointed head; when the third part 3 terminates in a pointed end, the angle of the chamfer is preferably between 30 and 45 degrees to the axis of the third part 3. The end parts of the suction pipe are all round and have the same diameter, so that the whole thickness of the adhered suction pipe is kept consistent.

The utility model discloses a straw of can buckling specially adapted liquid beverage packing, but the utility model discloses be not limited to this, the utility model discloses also be applicable to the product of other packagings simultaneously, for example the product in the aspect of food, medicine.
