Safety-lock structure for packaging box

Abstract

The present application discloses a container for preventing children from opening, including a cover body (10) and a container body (20) having a neck finish (21). The neck finish (21) is provided with external threads, and the cover body (10) is provided with internal threads. The side wall of the cover body (10) is provided with at least two pressing portions (13), and the inner wall of each pressing portion (13) is provided with a flexible snap (11). The upper end surface of the container body (20) is provided with a blocking portion (23) corresponding to each flexible snap (11). When the cover body (10) and the container body (20) are screwed tightly, the flexible snaps (11) and the blocking portions (23) are engaged with each other. The advantages are that when the cover body (10) needs to be opened, it requires the container body (20) to be held by one hand, and the pressing portions (13) are pressed by the other hand, so that the flexible snaps (11) and the blocking portions (23) are separated from each other, and the cover body (10) is rotated, so that the cover body (10) can be opened. Due to the limitations of the size of children's hands, children cannot press the two pressing portions (13) with one hand, thus cannot open the cover body (10), this can prevent children from eating the contents of the container body (20). During the process of tightening the cover body (10) and the container body (20), the blocking portions (23) slide into and are engaged with the notch snap grooves (113), and the cover body (10) and the container body (20) are stably closed. (Fig 5.)

Description

Invention Title: A Safety Lock Structure for Packaging Boxes

[0001] This application is based on and claims priority to Chinese Patent Application No. 201822071631.9, filed on December 10, 2018, the entire contents of which are incorporated herein by reference.

[0002] Technical Field

[0003] This application relates to the field of container technology, and in particular to a safety locking structure for packaging boxes.

[0004] Background Technology

[0005] 5. Some containers generally consist of a container body and a lid that fits the container body. After opening the lid, the liquid or some loose items inside the container can be poured out. When the container contains small particles or corrosive substances, children can easily open the container, so children can easily ingest them by mistake.

[0006] Application content

[0007] The purpose of this application is to address the shortcomings of existing technologies and provide a security lock structure for packaging boxes.

[0008] One technical solution of this application:

[0009] A packaging box safety lock structure includes a lid and a container body with a neck opening. The neck opening has an opening and an external thread on its outer wall. The inner wall of the lid has an internal thread that is threaded to the external thread. The side wall of the lid has at least two pressing parts, and the inner wall of the pressing parts has an elastic buckle. The upper end face of the container body has a blocking part corresponding to the elastic buckle. When the lid and the container body are screwed together, the elastic buckle and the blocking part are locked together.

[0010] A preferred embodiment is that the surface of the cover is recessed inward, the inner wall of the recess forms the pressing part, and the elastic buckle is disposed on the inner wall of the recess and close to the center of the cover.

[0011] A preferred embodiment is that a notch is provided between the bottom of the recess and the pressing part.

[0012] A preferred embodiment is that the elastic buckle includes a base portion and an elastic block disposed on the lower surface of the base portion and close to one side of the base portion; a notch and groove are formed between the elastic block and the other side of the base portion, and when the cover and the container body are screwed together, the blocking portion and the notch and groove are locked together.

[0013] A preferred embodiment is that the elastic block is provided with a guide plate that is aligned with the rotation direction of the internal thread. When the cover and the container body are screwed together, the blocking part slides into the notch groove along the guide plate.

[0014] A preferred embodiment has two elastic buckles, which are arranged facing each other on the inner wall of the cover.

[0015] In summary, the beneficial effects of this application are as follows: When it is necessary to open the lid, one hand needs to hold the container body and the other hand needs to press the pressing part, so that the elastic buckle and the blocking part disengage from each other. At the same time, the lid can be rotated to open it. Due to the size limitation of children's hands, children cannot press both pressing parts with one hand and cannot open the lid, which can prevent children from accidentally swallowing the contents of the container body; During the process of tightening the lid and the container body, the blocking part slides into the notch and slot and locks with the notch and slot, so the lid and the container body are stably closed.

[0016] The above description is merely an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it according to the contents of the specification, and to make the above and other objects, features and advantages of this application more apparent, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0025] Detailed Implementation

[0026] To illustrate the ideas and objectives of this application, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0027] As shown in Figures 1 to 7, a packaging box safety lock structure includes a lid 10 and a container body 20 with a neck opening 21. The neck opening 21 has an opening 22, and the outer wall of the neck opening 21 is provided with external threads. The inner wall of the lid 10 is provided with internal threads that are threadedly connected to the external threads. The side wall is provided with at least two pressing parts 13. The inner wall of the pressing part 13 is provided with an elastic buckle 11. The upper end face of the container body 20 is provided with a blocking part 23 corresponding to the elastic buckle 11. When the lid 10 and the container body 20 are screwed together, the elastic buckle 11 and the blocking part 23 are locked together.

[0028] As shown in Figures 1 to 7, when it is necessary to open the lid 10, the pressing part 13 needs to be pressed to disengage the elastic buckle 11 from the blocking part 23. At the same time, the lid 10 can be rotated to open it. Due to the limitations of children's strength and hand size, children cannot open the lid 10, which can prevent children from accidentally eating the food in the container body 20. During the process of tightening the lid 10 and the container body 20, the elastic buckle 11 and the blocking part 23 are locked together, so the lid 10 and the container body 20 are stably closed.

[0029] As shown in Figures 1 to 7, the surface of the cover 10 is recessed inward with a recess 12. The inner wall of the recess 12 forms the pressing part 13, which is close to the center of the cover 10. An elastic buckle 11 is disposed on the inner wall of the recess 12 and close to the center of the cover 10. The recess 12 is close to the lower side of the cover 10. The cover 10, the pressing part 13 and the elastic buckle 11 are integrally formed, and the blocking part 23 is integrally formed with the container body 20.

[0030] As shown in Figures 1 to 7, a notch 14 is provided between the bottom 15 of the recessed part 12 and the pressing part 13, so the pressing part 13 has a certain elasticity, which makes it convenient for the elastic buckle 11 and the blocking part 23 to be locked together or disengaged.

[0031] As shown in Figures 1 to 7, the elastic buckle 11 includes a base portion 111 and an elastic block 112 disposed on the lower surface of the base portion 111 and close to one side of the base portion 111. The base portion 111 is fixedly connected to the inner wall of the pressing portion 13. A notch groove 113 is formed between the elastic block 112 and the other side of the base portion 111. The notch groove 113 is L-shaped. When the cover 10 and the container body 20 are screwed together, the blocking portion 23 slides into the notch groove 113, so that the blocking portion 23 and the notch groove 113 are locked together. Preferably, the elastic block 112 is provided with a guide piece 114 that is consistent with the rotation direction of the internal thread. The guide piece 114 has an arc-shaped structure. When the cover 10 and the container body 20 are screwed together, the blocking portion 23 slides into the notch groove 113 along the guide piece 114.

[0032] As shown in Figures 1 to 7, there are two pressing parts 13, which are arranged facing each other on the side wall of the lid 10; there are two elastic buckles 11, which are arranged facing each other on the inner wall of the lid 10; there are two blocking parts 23, which are arranged facing each other on the inner wall of the lid 10. When it is necessary to open the lid 10, press the pressing part 13 with your thumb and middle finger at the same time, so that the blocking part 23 disengages from the notch slot 113, and rotate the lid 10 to open it. Due to the limitations of children's strength and hand size, children cannot open the lid 10, which can prevent children from accidentally ingesting food in the container body 20; during the process of tightening the lid 10 and the container body 20, the elastic buckles 11 and the blocking parts 23 are locked together, so the lid 10 and the container body 20 are stably closed.

[0033] The above describes the specific embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application. Refinement is also considered within the scope of protection of this application. Invention Summary Technical issues Solution to the problem Beneficial effects of the invention
