Embodiment 1

[0045] A squeeze bottle with a pouch, such as Figure 3-8 As shown, it includes an inner bag 3, a bottle body 22 and a pump head 1 connected to the bottle body 22;

[0046] The inner bag 3 is located in the bottle body 22, the opening of the inner bag 3 is connected with the opening of the bottle body 22, and the bottom of the bottle body 22 has a through hole III 23 communicating with the outside;

[0047] The minimum elastic modulus of the material of the bottle body 22 is not less than 850MPa, and it is mainly composed of the inner layer of the bottle and the outer layer of the bottle. The inner layer of the bottle is made of PP material, and the outer layer of the bottle is made of PP soft touch material. The inner material of the bottle is not bonded to EVOH, the thickness of the inner layer of the bottle is 0.2mm, and the thickness of the outer layer of the bottle is 0.6mm;

[0048] The inner bag 3 includes an EVOH layer and an LDPE layer located on the outermost side o...

Embodiment 2

[0062] A press bottle with bag, which is basically the same as Example 1, the difference lies in the thickness of each layer of the bottle body and the inner bag, the thickness of the inner layer of the bottle is 0.3mm, the thickness of the outer layer of the bottle is 0.3mm, and the thickness of the EVOH layer The thickness of the LDPE layer is 0.1mm, and the thickness of the layer formed by the adhesive is 0.01mm.

Embodiment 3

[0064] A press bottle with bag, which is basically the same as Example 1, except that the thickness of each layer of the bottle body and the inner bag is different, the thickness of the inner layer of the bottle is 0.1mm, the thickness of the outer layer of the bottle is 1mm, and the thickness of the EVOH layer is 0.07mm, the thickness of the LDPE layer is 0.2mm, and the thickness of the layer formed by the adhesive is 0.02mm.

Abstract

The invention discloses a pressing bottle with a bag, which comprises an inner bag, a bottle body and a pump head connected with the bottle body; the inner bag is located in the bottle body, and the opening of the inner bag is connected with the opening of the bottle body; The minimum elastic modulus of the bottle body is not less than 850MPa and the inner wall of the bottle is not bonded to EVOH; the inner bag includes EVOH layer and LDPE layer, and the EVOH layer and LDPE layer are bonded by adhesive, EVOH The layer is located on the outermost side of the inner bag; the air will not enter the inner bag from the outside of the bottle when the pump head is pressed and rebounded. The present invention has less use residue and good user experience; it can isolate the contents in the bottle and improve the quality and shelf life of the contents; it has unique design, simplified structure, low cost, and the shape and size of the bottle body is controllable and beautiful; after use The bottle body is separated from the inner bag, and there is no residual content in the bottle body, which can be recycled directly, which is energy-saving and environmentally friendly, and has great application prospects.

Description

technical field [0001] The invention belongs to the technical field of packaging, relates to a press bottle with a bag, in particular to a press bottle with a bag which has less residue, can isolate the content in the bottle and has a simple structure. Background technique [0002] With the development of society and the continuous enrichment of people's material life, people's requirements for the quality of life are getting higher and higher. Press bottle is a common packaging tool, which is mostly used as a packaging bottle for skin care and cosmetic products such as water, lotion, and isolation, or daily care products such as shampoo and shower gel. figure 1 As shown, it is mainly composed of a bottle body and a pressing pump head. The principle of use is that by pressing the pump head, air enters the bottle body through the pump head, and at the same time, the air squeezes the contents in the bottle to squeeze out the contents. It mainly has the following two major def...
