AI Technical Summary
Existing medicine bottles are easily opened by children, posing a safety hazard, especially if parents do not notice in time, which may lead to accidental ingestion of medicine and adverse reactions.
A polypropylene medicine bottle assembly including an outer shell and a limiting unit was designed. The outer shell is provided with a groove and a bevel, and the limiting unit includes a U-shaped locking rod and a combination lock. The groove and bevel design prevents the medicine bottle from detaching from the outer shell, and the combination lock controls the opening of the medicine bottle.
This improves the protective effect of the medicine bottle, preventing children from opening it easily, reducing the risk of accidental ingestion of medicine, and enhancing safety.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bottle technology and relates to a polypropylene medicine bottle assembly. Background Technology
[0002] Medicine bottles are storage tools used to store medications. Every household stores some medicines for relieving daily symptoms or for patients. However, most medicine bottles have a twist-open mechanism. In families with children, children are relatively active and lack understanding of medicine bottles. If parents are not paying attention, they may play with the medicine bottle. During this process, the bottle may be damaged, causing the medicine to fall out. It may also be opened, leading to accidental ingestion of the medicine, which may cause adverse reactions. If not dealt with promptly, it may lead to damage to their health. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a medicine bottle assembly that offers good protection and is not easily opened.
[0004] The objective of this utility model can be achieved through the following technical solution: A polypropylene medicine bottle assembly, comprising a medicine bottle body, characterized in that it further comprises an outer shell for mounting the medicine bottle body, wherein an axially inwardly extending groove is provided on the upper end surface of the outer shell and slides in cooperation with the medicine bottle body, and an inclined surface is provided on the outer peripheral wall of the lower end of the outer shell, which connects the groove to the outside and facilitates the medicine bottle body to detach from the inclined surface of the outer shell, and a limiting unit is provided on the outer peripheral wall of the outer shell and connected thereto, which is used to limit the position of the medicine bottle body and prevent the medicine bottle body from detaching from the outer shell.
[0005] In the aforementioned polypropylene medicine bottle assembly, the limiting unit includes a combination lock with a locking bar and a combination dial. The locking bar is U-shaped, and the upper end of the locking bar is bent and fitted to the body of the medicine bottle, forming a U-shaped folded edge.
[0006] In the aforementioned polypropylene medicine bottle assembly, the inner wall of the outer shell located at the slide groove is provided with a plurality of positioning grooves spaced apart along its circumference, and the outer peripheral wall of the medicine bottle body located at the positioning groove is provided with a positioning block connected to and cooperating with the positioning groove.
[0007] Compared with existing technologies, this polypropylene medicine bottle assembly, through the setting of an outer shell and a limiting unit, provides better protection for the main body of the medicine bottle and makes it less likely for children to open. Attached Figure Description
[0008] Figure 1 This is a three-dimensional structural diagram of the polypropylene medicine bottle assembly.
[0009] In the picture, 1. the main body of the medicine bottle; 2. the outer shell; 3. the locking bar; 4. the combination lock. Detailed Implementation
[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0011] like Figure 1 As shown, this polypropylene medicine bottle assembly includes a medicine bottle body 1 and an outer shell 2 for mounting the medicine bottle body 1. The upper surface of the outer shell 2 has an axially inwardly extending groove that slides with the medicine bottle body 1. The lower end of the outer shell 2 has an inclined surface on its outer peripheral wall, which connects the groove to the outside and facilitates the medicine bottle body 1's disengagement from the inclined surface of the outer shell 2. This inclined surface extends from the outer peripheral wall of the outer shell 2 to its lower end. The outer peripheral wall of the outer shell 2 has a limiting unit connected to it, used to restrict the position of the medicine bottle body 1 and prevent it from disengaging from the outer shell 2. The limiting unit includes a combination lock 4 with a locking rod 3 and a combination dial. The locking rod 3 is U-shaped. The structure is designed such that the upper end of the locking rod 3 is bent and fitted with the main body of the medicine bottle 1 in a U-shape. When the locking rod 3 is locked with the combination lock 4, the folded edge fits into the main body of the medicine bottle 1. When needed, the combination dial is rotated to open the combination lock 4, allowing the locking rod 3 to be pulled upward and rotated circumferentially, thus allowing the main body of the medicine bottle 1 to detach from the outer shell 2. The inner wall of the outer shell 2 at the sliding groove has several positioning grooves spaced circumferentially. The outer wall of the main body of the medicine bottle 1 at the positioning groove has a positioning block connected to it and cooperating with the positioning groove. Through the positioning block, the main body of the medicine bottle 1 will not slip with the outer shell 2 when opened.
[0012] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0013] Although this document uses terms such as "etc." extensively, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
