Problems solved by technology

[0002] Compared with fresh milk, yogurt is fermented, so its nutrients are more easily absorbed by the human body, and it is more suitable for people with lactose intolerance, but the shelf life of yogurt is only 14-21 days, and it must be stored in the cold chain. Its production and sales have caused great restrictions
Although commercially available yogurt machines and other products allow people to make homemade yogurt, there are many operating steps and problems such as cleaning after use.
Can't fully adapt to the fast-paced life of today's society

Embodiment Construction

[0009] The virtual weld processing adopts the virtual weld welding equipment disclosed in Chinese patent CN200620087996.5

[0010] Such as figure 1 As shown, the dimensions of the rectangular packaging bag used are 10cm×15cm, and the virtual weld seam is close to the corner 2 of the bag. During production, the upper and lower ends of the packaging bag are sealed by heat and pressure respectively, and then the virtual weld seam 3 is welded on the bag. Seam 3 is a V-shaped line, and the two endpoints 3.1 and 3.2 are respectively located on the sides 4.1 and 4.2 of the packaging bag. The bottom angle α of the V-shaped virtual weld is 60°, and the angle bisector of the bottom angle is on the diagonal line of the packaging bag. It is 1.5cm away from the corner 2 of the bag. During the packaging operation, the liquid storage chamber 2.1 can be filled with milk and sealed; the yogurt starter can be added to the storage chamber 2.2 and sealed; the packaged milk can be obtained.

Abstract

The invention discloses a packaging bag with a V-shaped cold solder joint seam. The packaging bag with the V-shaped cold solder joint seam is characterized in that The V-shaped cold solder joint seam (3) close to a corner (2) of a rectangular packaging bag body (1) partitions the packaging bag body (1) into a storage cavity (2.1) and a storage cavity (2.2), two endpoints (3.1 and 3.2) of the V-shaped cold solder joint seam (3) are positioned at edges (4.1 and 4.2) of the packaging bag body (1) respectively, and an opening of the V-shaped cold solder joint seam (3) faces the corner (2) of the rectangular packaging bag body (1). A base angle (alpha) of the V-shaped cold solder joint seam (3) is 45-60 degrees. The distance from the base angle (3.3) of the V-shaped cold solder joint seam (3) to the corner (2) of the rectangular packaging bag body (1) is at most 10% of the length of the diagonal line of the rectangular packaging bag body (1).

Description

field of invention [0001] The invention relates to a food package, especially a package of dairy products. Background technique [0002] Compared with fresh milk, yogurt is fermented, so its nutrients are more easily absorbed by the human body, and it is more suitable for people with lactose intolerance, but the shelf life of yogurt is only 14-21 days, and it must be stored in the cold chain. Its production and sales have caused great restrictions. However, commercially available yogurt machines and other products allow people to make homemade yogurt, but there are many operating steps and problems such as cleaning after use. Can not fully adapt to the fast-paced life of today's society. Contents of the invention [0003] The invention provides a packaging bag for packaging milk, which is characterized in that the packaging bag (1) is rectangular, and there is a storage space separated by a V-shaped virtual weld (3) near the corner (2) of the packaging bag. Cavity (2.1)...
