Description

Technical Field

[0001] This utility model relates to the field of packaging bottle manufacturing technology, specifically a paper-plastic packaging bottle. Background Technology

[0002] In daily life, liquid items such as hand sanitizer and serums, as well as lotion-like products such as shower gel and body lotion, are mostly packaged in bottles. Common packaging bottles, depending on the material, include glass bottles and plastic bottles, with plastic bottles being more widely used due to their lighter weight.

[0003] Since the aforementioned hand sanitizers, serums, shower gels, and body lotions are applied directly to human skin, the safety requirements for the plastics used in their packaging bottles are high, resulting in higher manufacturing costs. Furthermore, the extensive use of plastic products pollutes the environment. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and disclose to the public a paper-plastic packaging bottle with a reasonable structure. It adopts a double-layer structure, with the outer layer made of paper material and the inner layer made of plastic material, which is conducive to reducing manufacturing costs. The outer paper material allows for more diverse printing processes, which is conducive to improving the aesthetics of product packaging.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A paper-plastic packaging bottle includes a packaging bottle body, the packaging bottle body including a plastic bottle body, a pump head assembly mounted on the plastic bottle body, a paper outer shell detachably disposed on the plastic bottle body, and a paper outer cap adapted to the paper outer shell disposed on the pump head assembly.

[0007] Further optimization measures for this technical solution are as follows:

[0008] As an improvement, the paper cover fits into the paper shell.

[0009] As an improvement, a limiting part is provided on the outer surface of the paper outer cover. The limiting part can limit the insertion depth of the paper outer cover and prevent the top surface of the paper outer cover from squeezing the pump head assembly and causing accidental leakage.

[0010] As an improvement, the paper outer shell has a cylindrical structure, and correspondingly, the paper cover also has a cylindrical structure.

[0011] As an improvement, the paper outer shell includes a paper outer shell body, a paper inner liner fixed inside the paper outer shell body, and a retaining ring fixed to the paper inner liner. The retaining ring is provided with several elastic parts. Using the retaining ring with elastic parts to fix the pump head assembly facilitates assembly and disassembly.

[0012] As an improvement, the paper outer shell has a square column structure, and correspondingly, the paper cover also has a square column structure.

[0013] As an improvement, the upper end of the paper outer shell is provided with a locking slot, on which the pump head assembly locks. This locking is achieved using the deformation of the paper material itself.

[0014] As an improvement, the plastic bottle body is a plastic vacuum bottle.

[0015] As an improvement, the plastic bottle body is a soft plastic tube with a sealed bottom.

[0016] The advantages of this utility model compared with the prior art are:

[0017] This utility model discloses a paper-plastic packaging bottle with a reasonable structure. It employs a double-layer structure: the inner layer, which contacts the stored contents, is made of plastic, while the outer layer is made of paper. This not only reduces manufacturing costs but also decreases the amount of plastic used, making it more environmentally friendly. The outer paper material allows for more sophisticated printing processes, enhancing the aesthetics of the product packaging. The plastic bottle body and paper outer shell are detachable, facilitating waste sorting and further promoting environmental protection. Attached Figure Description
