Problems solved by technology

[0003] The high-barrier bottle is provided with a barrier interlayer inside the bottle body, which effectively avoids the impact of light, air and moisture on the shelf life of the contents. The barrier material is molded inside the bottle body by blow molding to form a barrier interlayer. However, when the barrier interlayer is blown, there is a certain amount of air inside the bottle body, resulting in insufficient fit between the barrier interlayer and the bottle body. There are some air bubbles between the body, which not only affects the appearance, but also affects the inner volume of the container
[0004] When producing containers that require transparency such as mineral water bottles, the barrier interlayer often affects the transparency of the bottle body, so the barrier material needs to be stretched, and the barrier interlayer can be placed inside the bottle body by extrusion blowing technology, but in this way Not only will it cause the barrier interlayer to not fit well with the bottle body after forming, but it will also be more cumbersome to manufacture

Embodiment 1

[0031] Embodiment one: if Figure 1 to Figure 6 As shown, a method for assembling a packaging bottle with an inner bag is carried out in sequence as follows: the first step: assembling parts; the second step: sealing; the third step: vacuuming; the fourth step: unfolding the inner bag 3; The fifth step: cutting.

[0032] Step 1: Assembling the parts; the vacuum tank 2 includes a first driver, the first driver is connected to the outer bottle 1, first the outer bottle 1 of the packaging bottle is installed in the vacuum tank 2 through the first driver, and the vacuum tank 2 The top of the top has a supporting surface, the supporting surface is provided with a sealing ring 6, the outer bottle 1 has a flange portion 7, the flange portion 7 is located on the sealing ring 6, and a seal is formed between the outer bottle 1 and the sealing ring 6, so that The inner cavity of the vacuum tank 2 is isolated from the atmosphere, and the outer wall of the inner bag 3 has a plurality of r...

Embodiment 2

[0038] Embodiment 2: The structure and principle of this embodiment are basically the same as that of Embodiment 1, and the basic similarities will not be described repeatedly, only the differences are described, and the differences lie in: the first step: assembling parts; vacuum tank 2 Including the first driving part, the first driving part is connected with the outer bottle 1, first the inner bag 3 is installed in the bottle mouth of the outer bottle 1, and then the outer bottle 1 of the packaging bottle is installed in the vacuum tank 2 through the first driving part.

Embodiment 3

[0039] Embodiment 3: The structure and principle of this embodiment are basically the same as those of Embodiment 1. The basic similarities will not be described redundantly, and only the differences will be described. The differences are as follows: Figure 7 As shown, the both sides of the inner bag 3 are rolled up and installed in the mouth of the outer bottle 1.

Abstract

The invention provides a method for assembling a packaging bottle with an inner bag, and belongs to the technical field of packaging containers. The problems that an existing blocking interlayer and a bottle body cannot be completely attached, and the assembling method is complex are solved. The assembling method of the packaging bottle with the inner bag sequentially comprises the following steps that firstly, components are assembled; step 2, sealing; thirdly, vacuumizing is conducted; fourthly, the inner bag is unfolded; and 5, blanking is conducted. According to the assembling method of the packaging bottle with the inner bag, the inner bag is unfolded and attached to the inner wall of the packaging bottle through the air pressure difference between the interior of the inner bag and the interior of the packaging bottle, so that the packaging bottle with the inner bag is obtained, the attractiveness is improved, the internal volume of a container is not affected, and the method is few in step and low in cost. And the packaging bottle with the inner bag can be efficiently and simply obtained.

Description

technical field [0001] The invention belongs to the technical field of packaging containers, and relates to an assembly method of a packaging bottle, in particular to an assembly method of a packaging bottle with an inner bag. Background technique [0002] Plastic bottles are mainly plastic containers that are blown, squeezed or injection molded through plastic molds. In the field of packaging, high barrier bottles are often used when packaging food, solvents and chemicals, especially in the food industry. It is used in aseptic packaging, hot canning, packaging meat and condiments, etc., to ensure that the food is not easy to deteriorate. [0003] The high-barrier bottle is provided with a barrier interlayer inside the bottle body, which effectively avoids the impact of light, air and moisture on the shelf life of the contents. The barrier material is molded inside the bottle body by blow molding to form a barrier interlayer. However, when the barrier interlayer is blown, t...
