  • 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.

    DETAILED DESCRIPTION OF THE SPECIFIC EMBODIMENTS
  • 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.
  • As shown in FIG. 1 to FIG. 7, a safety-lock structure for a packaging box includes a cover body 10 and a container body 20 with a neck finish 21, the neck finish 21 has an opening 22 , the outer wall of the neck finish 21 is provided with external threads; the inner wall of the cover body 10 is provided with internal threads which are in screw connection with the external threads, and the side wall is provided with at least two pressing portions 13; 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 that corresponds to each flexible snap 11. When the cover body 10 and the container body 20 are screwed tightly to each other, the flexible snaps 11 are engaged with the blocking portions 23.
  • As shown in FIG. 1 to FIG. 7 , when the cover body 10 needs to be opened, it requires to press the pressing portions 13 , so that the flexible snaps 11 and the blocking portions 23 are separated from each other, and rotate the cover body 10 at the same time to open the cover body 10. Due to the limitations of children's strength and the size of their hands, children cannot open the cover body 10, hence children can be prevented from ingesting the food in the container body 20; during the tightening of the cover body 10 and the container body 20, the flexible snaps 11 and the blocking portions 23 are engaged with each other, so that the cover body 10 and the container body 20 are stably closed.
  • As shown in FIG. 1 to FIG. 7, the surface of the cover body 10 is recessed inward and provided with recessed portions 12, and the inner side wall of the recessed portion 12 forms the pressing portion 13, and the pressing portion 13 is adjacent to the center of the cover body 10, the recessed portions 12 are adjacent to the lower side of the cover body 10. The cover body 10, the pressing portions 13 and the flexible snaps 11 are integrally formed, and the blocking portions 23 are integrally formed with the container body 20.
  • As shown in FIG. 1 to FIG. 7, a slit groove 14 is provided between the bottom portion 15 of the recessed portion 12 and the pressing portion 13, so that the pressing portion 13 has certain elasticity, facilitating the flexible snap 11 and the blocking portion 23 to be engaged with or separated from each other.
  • As shown in FIG. 1 to FIG. 7, each flexible snap 11 includes a base portion 111, and a flexible block 112 disposed on a lower surface of the base portion 111 and adjacent 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 snap groove 113 is formed between the flexible block 112 and the other side of the base portion 111. The notch snap groove 113 is in an L shape. When the cover body 10 and the container body 20 are screwed tightly to each other, the blocking portions 23 slide into the notch snap grooves 113, hence the blocking portions 23 are engaged with the notch snap grooves 113. Preferably, the flexible blocks 112 are provided with guiding pieces 114 which are in the same direction as the rotating direction of the internal threads. The guiding pieces 114 have an arc-shaped structure. When the cover body 10 and the container body 20 are being screwed tightly together, the blocking portions 23 slide along the guiding pieces 114 and snap into the notch snap grooves 113.
  • As shown in FIG. 1 to FIG. 7, the number of the pressing portions 13 is two, and the two pressing portions 13 are disposed opposite to each other on the side wall of the cover body 10; the number of the flexible snaps 11 is two, and the two flexible snaps 11 are disposed opposite to each other on the inner wall of the cover body 10. The number of the blocking portions 23 is two, and the two blocking portions 23 are disposed opposite to each other on the inner wall of the cover body 10. When the cover body 10 needs to be opened, the pressing portions 13 are simultaneously pressed by the thumb and the middle finger, so that the blocking portions 23 are separated from the notch snap grooves 113, and at the same time the cover body 10 is rotated, so that the cover body 10 can be opened. Due to the limitations of children's strength and the size of their hands, children cannot open the cover body 10, hence can be prevented from ingesting the food in the container body 20; during the tightening of the cover body 10 and the container body 20, the flexible snaps 11 and the blocking portions 23 are engaged with each other, so that the cover body 10 and the container body 20 are stably closed.
  • The above is a specific embodiment of the present application. It should be noted that those skilled in the art can also make improvements and refinements without departing from the scope of the appended claims.
