Description

Beverage pouch with spout tear-off sticker

This creation is related to the structure of the beverage container, especially a beverage bag with an easy-to-tear sticker for the mouth.

There are many known beverage packaging methods, the most common of which is the use of Tetra Pak (generally refers to all packaging products produced by Tetra Pak "Tetra Pak", about 70% of the typical Tetra Pak packaging is paper, and it also contains Glue and aluminum foil. In addition to the plastic cover of the bottle mouth, a typical Tetra Pak has a total of 7 layers of structure. From the surface layer to the inside: glue (polyethylene, PE), printing layer, paper, adhesive glue (polyethylene) , aluminum foil, adhesive glue (polyethylene), glue (polyethylene). Due to the 7-layer structure of Tetra Pak, it has the ability to block ultraviolet rays, the overall structural strength is good, and it has good fresh-keeping ability for beverages or foods. Or food types, the preservation ability can reach several months or even 12 months. Generally speaking, Tetra Pak milk that has been sterilized by ultra-high temperature can be stored for 30-60 days in a perfect refrigerated environment (below 7°C). However, considering various factors such as circulation, sales, and home environment, dairy manufacturers set the shelf life at about 10 days. If it is the shelf life of Tetra Pak long-lasting milk, it can even be as long as 12 months. However, the use of The packaging cost of Lebao is high. For some low-priced beverage manufacturers, the use of high-cost packaging will increase the price of the product, thereby reducing the competitiveness of the product.

Another widely used beverage packaging method is to use plastic bags (such as plastic bags made of polyethylene (PE) and polypropylene (PP)), because the manufacturing cost of plastic bags is very low, and plastic bags are very suitable for automatic continuous production operation, on a known beverage production line, rolls of plastic The bags are continuously fed into the automatic filling and packaging machine for beverages, combined with thermal fusion or ultrasonic fusion, the automatic filling and packaging of beverages can be quickly completed. Therefore, plastic bags are widely used in low-cost Beverage packaging; however, plastic bags do not have the ability to block ultraviolet rays or block ultraviolet rays, and the ability to keep beverages fresh is not as good as Tetra Pak, so they are not suitable for packaging beverages that require higher freshness conditions, such as milk packaged in plastic bags , the shelf life will be greatly reduced to a few days, or even less than a week (7 days); on the other hand, plastic bags that are simply sealed by thermal fusion or ultrasonic fusion are extremely inconvenient to open. Especially when the user directly disassembles the plastic bag for beverage with bare hands, it is easy to spill the beverage while tearing the plastic bag, causing inconvenience to the user.

The main purpose of the present invention is to provide a beverage bag with good fresh-keeping ability, low cost and easy to use, which has an easy-to-tear sticker at the mouth.

In order to achieve the above-mentioned purpose, the preferred embodiment structure of the beverage bag with the easy-to-tear sticker at the mouth of the creation includes:

A three-layer paper bag is an airtight bag made of three layers of paper, wherein the structure of the three layers of paper includes: a first waterproof paper layer, a second waterproof paper layer and an aluminum foil paper layer, the first waterproof paper layer, the second waterproof paper layer and the aluminum foil paper layer are overlapped and pasted together, the aluminum foil paper layer is between the first waterproof paper layer and the second waterproof paper layer, the first waterproof paper layer is used as the outer layer of the beverage bag, and the second waterproof paper layer is The paper layer is used as the inner layer of the beverage bag, and the predetermined position of the three-layer paper bag is provided with a cross-shaped cut that penetrates the three-layer paper; and

An easy-to-tear sticker, its structure includes: a sealing portion, and a force application portion extending outward from the edge of the sealing portion, the sealing portion is bonded to the outside of the three-layer paper bag by at least two concentric annular adhesive lines On the side surface, the annular bonding line surrounds the periphery of the cross-shaped incision.

In this invention, there is an embodiment of the beverage bag with the easy-to-tear sticker for the mouth, wherein the cross-shaped incision is flat and formed by cross-shaped continuous cutting or punching.

In an embodiment of the beverage bag with the easy-to-tear sticker for the mouth of the invention, the cross-shaped incision is a discontinuous line segment or a crack formed by a zigzag line segment.

In this invention, there is an embodiment of the beverage bag with the easy-to-tear sticker for the mouth, wherein the shape of the sealing portion of the easy-tear sticker is circular.

In an embodiment of the drink bag with the easy-to-tear sticker for the mouth of the creation, the three-layer paper bag is a closed bag with three sealing edges, and the three sealing edges include: a first seal A sealing edge, a second sealing edge, and a third sealing edge; wherein the left and right sides of the three layers of paper are bonded to each other to form the first sealing edge and form a tubular body, and the opening at one axial end of the tubular body is bonded to form the second sealing edge. For the sealing edge, the opening at the other axial end of the tubular body is bonded to form a third sealing edge.

In an embodiment of the beverage bag with a mouthpiece tear-off sticker in this invention, the first sealing edge, the second sealing edge and the third sealing edge are bonded by means of thermal fusion or ultrasonic fusion Sealing edge formed by three layers of paper.

The beverage bag with the easy-to-tear sticker on the mouth of this creation is suitable for beverage packaging, especially for beverages that require better fresh-keeping ability. The advantages and effects of this creation are:

1. Good freshness preservation ability; compared with ordinary plastic bags used for packaging beverages, this creation uses three-layer paper to make the main bag body of the beverage bag. The aluminum foil paper layer has the ability to block ultraviolet rays and has better freshness preservation ability.

2. Reduce the packaging cost; compared with the Tetra Pak with 7-layer structure, this creation uses three-layer paper to make the main bag body of the beverage bag, which can reduce the packaging cost.

3. Easy to use; this creation has a beverage bag with an easy-to-tear sticker for the mouth, and a cross-shaped incision that penetrates the three-layer paper is provided at the predetermined position of the three-layer paper bag as the drinking mouth of the beverage or the insertion port of the straw, and in ten An easy-tear sticker is affixed to the glyph cutout, and it is convenient to drink or pour out the beverage as long as the easy-tear sticker is torn off during use.
