Problems solved by technology

[0003] The more common one is to use the above-mentioned various plastic materials to manufacture an inner container by injection blowing process, and then set a shell made of other plastic materials outside the inner container. The structure of the packaging bottle with this structure is complicated and the manufacturing cost is high.
[0004] There is also a packaging bottle that is also injection-molded using the above-mentioned various plastic materials. This packaging bottle directly contains cosmetics, eliminating the need for a shell structure, but it is necessary to open air holes at the bottom and set a piston in the bottle. The structure is also complicated. Manufacturing high cost
[0005] Another kind of packaging bottle with lower manufacturing cost and more commonly used is made of transparent PET, which is completed through a series of processes such as injection molding and blow molding. Due to the particularity of its process, most PET packaging bottles are of thin-walled structure. Poor strength, prone to uneven thickness, unattractive appearance, low-grade thin-wall structure, unable to meet the thick-wall requirements of high-end cosmetic packaging bottles;
[0006] Therefore, high-end cosmetics on the market generally use glass packaging bottles or PETG plastic bottles. PETG materials are expensive and not widely used; although the cost of glass bottles is low, they are fragile and heavy, and the transportation cost is relatively high.

Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] Such as figure 1 , 2 As shown, a cosmetic packaging container includes a cosmetic packaging container, including an upper bottle body, a lower bottle body 1 and a bottle cap 2, and the lower bottle body includes a mouth 11, a bottom 12 and an inner sidewall 13; specifically, The bottom 12 of the lower bottle body is a sealed structure, so the bottle body does not need a piston, and can directly contain cosmetics; the inner side wall 13 of the lower bottle body is formed by injection molding at one time, so the mouth size of the lower bottle body is the same as the size of the inner wall Or similar, similar means that the size of the mouth and the inner wall are not mu...

Abstract

The invention discloses a packaging container for cosmetics. The packaging container comprises an upper bottle body and a lower bottle body. The lower bottle body comprises a mouth portion, a sealed bottom and an inner side wall formed by one-time forming via injection technology. A discharge port used for decreasing the size of the mouth portion is formed in the upper bottle body and communicated with the mouth portion. The upper bottle body at least comprises an inner part piece including a body with the discharge port, a neck portion formed by extending upwards along the discharge port and an inner sealing wall at least matched with the inner side wall of the mouth portion in a sealing mode. The packaging container for cosmetics has following beneficial effects: by dividing a bottle body into an upper and a lower part, the purpose of decreasing the size of the mouth portion of the lower bottle body is fulfilled; the inner wall of the lower bottle body is formed by one-time forming via injection technology and is more manufactured conveniently in an energy-saving mode; the lower bottle body formed by one-time forming via injection technology has a uniform wall thickness and high strength and satisfies the packaging standard of high-end cosmetics; due to the fact that the sealing wall is matched with the inner side wall of the mouth portion of the lower bottle body, attractiveness and safety of using the container are ensured.

Description

technical field [0001] The invention belongs to the field of packaging containers, in particular to a cosmetic packaging container. Background technique [0002] Due to the special chemical composition of cosmetics, cosmetic bottles are mainly made of glass or opaque PP, PE or transparent PET, PETG and other plastic materials; the packaging bottles currently on the market are mainly as follows: [0003] The more common one is to use the above-mentioned various plastic materials to manufacture an inner container by injection blowing process, and then cover the inner container with a shell made of other plastic materials. The structure of the packaging bottle with this structure is complicated and the manufacturing cost is high. [0004] There is also a packaging bottle that is also injection-molded using the above-mentioned various plastic materials. This packaging bottle directly contains cosmetics, eliminating the need for a shell structure, but it is necessary to open air ...
