Safety-Lock Structure for Packaging Box
The present application discloses a container for preventing children from opening, including a cover body and a container body having a neck finish. The neck finish is provided with external threads, and the cover body is provided with internal threads. The side wall of the cover body is provided with at least two pressing portions, and the inner wall of each pressing portion is provided with a flexible snap. The upper end surface of the container body is provided with a blocking portion corresponding to each flexible snap. When the cover body and the container body are screwed tightly, the flexible snap and the blocking portion are engaged with each other.
The present application is a continuation application of International Application No. PCT/CN2019/092474 filed on Jun. 24, 2019, which claims priority of Chinese Patent Application No. 201822071631.9 filed on Dec. 10, 2018. The contents of the applications are incorporated herein by reference in their entireties.
TECHNICAL FIELDThe present application relates to the field of container technology, and more particularly to a safety-lock structure for a packaging box.
BACKGROUNDThe existing containers generally comprise a container body and a cover body covering the container body. After opening the cover body, the liquid or some scattered particles filled in the container can be poured out; when the container is filled with small or corrosive particles, the container can be easily opened by children, hence causes ingestion by mistake.
SUMMARY OF THE APPLICATIONAn object of the present application is to provide a safety-lock structure for a packaging box by solving the disadvantages of the prior art.
A technical solution of the present application is:
A safety-lock structure for packaging box includes a cover body and a container body with a neck finish, the neck finish has an open mouth, an outer wall of the neck finish is provided with external threads, an inner wall of the cover body is provided with internal threads in thread connection with the external threads; a side wall of the cover body is provided with at least two pressing portions, an inner wall of each pressing portions is provided with a flexible snap, an upper end surface of the container body is provided with a blocking portion that corresponds to each flexible snap. The flexible snaps and the blocking portions are engaged with each other after the cover body and the container body are screwed tightly to each other.
In a preferred solution, the surface of the cover body is recessed inward and provided with recessed portions, and the inner side wall of the recessed portion forms the pressing portion, and the flexible snap is disposed on the inner side wall of the recessed portion and is close to the center of the cover body.
In a preferred solution, a slit groove is provided between the bottom part of the recessed portion and the pressing portion.
In a preferred solution, each flexible snap includes a base portion, and a flexible block disposed on a lower surface of the base portion and adjacent to a side of the base portion; a notch snap groove is formed between the flexible block and the other side of the base portion, the blocking portion and the notch snap groove are engaged with each other after the cover body and the container body are screwed tightly to each other.
In a preferred solution, each flexible block is provided with a guiding piece which is in the same direction as the rotating direction of the internal threads. When the cover body and the container body are being screwed tightly together, the blocking portion slides along the guiding piece and snaps into the notch snap groove.
In a preferred solution, the number of the flexible snaps is 2, and the 2 flexible snaps are disposed opposite to each other on the inner wall of the cover body.
In combination with the above technical solutions, the present application has the following beneficial effects: when the cover body needs to be opened, it requires to hold the container body by one hand, and press the pressing portions by the other hand, so that the flexible snaps and the blocking portions are separated from each other, then rotate the cover body at the same time to open the cover body. Due to the limitations of the size of children's hands, children are not able to press the two pressing portions with one hand, thus they cannot open the cover body, therefore, it can prevent children from eating the contents of the container body; during the process of tightening the cover body and the container body, the blocking portions slide into the notch snap grooves and are engaged with the notch snap grooves, so that the cover body stably covers the container body.
The above description is only an overview of the technical solutions of the present application, and the technical means of the present application can be more clearly understood, and can be implemented in accordance with the contents of the specification, and the above and other objects, features and advantages of the present application can be more clearly understood by the detailed preferred embodiments described hereinafter, with reference to the accompanying drawings.
To clarify the idea and purpose of the present application, the present application will be further described with reference to the accompanying drawings and specific embodiments.
