Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention is further described with reference to the accompanying drawings and examples.

As shown in fig. 1-6, in one embodiment of the present invention, the packaging container includes a container body 10, a cover body 20 connected to the container body 10, and a snap sleeve 30 disposed between the container body 10 and the cover body 20. The container body 10 is formed by a blow molding process, and the cover body 20 and the snap sleeve 30 are formed by an injection molding process. A neck finish 11 with an upward opening 12 is arranged on the top surface of the container body 10; a socket 32 for the neck finish 11 to pass through is formed in the center of the snap-fit sleeve 30, the socket 32 is externally sleeved on the neck finish 11, and the snap-fit sleeve 30 is attached to the top surface of the container body 10 and fixed to the container body 10. A blocking block 33 is formed on the upper surface of the snap sleeve 30, an elastic pressing portion 21 is formed on the side wall of the cover body 20, and when the cover body 20 and the container body 10 are screwed tightly, the blocking block 33 and the elastic pressing portion 21 are matched to block the cover body 20 from screwing out.

As shown in fig. 7-8, when the cover 10 needs to be opened, the elastic pressing portion 21 needs to be pressed, the elastic pressing portion 21 is forced to separate the elastic pressing portion 21 and the stopper 33, and the cover 10 is rotated to open the cover 10. When a child wants to open the lid 10, the child cannot exert enough force on the elastic pressing portion 21 to separate the elastic pressing portion 21 and the blocking piece 33 from each other due to the limitation of strength of the child and the size of the hand, and at this time, the blocking piece 33 and the elastic pressing portion 21 continue to cooperate to block the lid 20 from being unscrewed, so that the child cannot open the lid 10, and the child can be prevented from eating the food in the container body 20 by mistake.

The packaging container in the embodiment of the invention comprises a container body 10, a cover body 20 and a buckle sleeve 30, wherein a stop block 33 is arranged on the buckle sleeve 30, and the container body 10 and the buckle sleeve 30 are formed separately, so that the condition that the container body 10 has poor stop point blow molding in the blow molding process is avoided, and the problem that the container body 10 has poor stop point blow molding in the forming process in the prior art is solved.

As shown in fig. 2 and 6, a plurality of fixing blocks 34 are arranged at the edge of the sleeve opening 32 of the snap-fit sleeve 30, and a plurality of fixing slots 14 which are matched and clamped with the fixing blocks 34 are arranged on the outer wall of the neck finish 11. When the snap sleeve 30 is sleeved on the neck finish 11, the fixed blocks 34 are correspondingly placed into the fixed slots 14, so that the snap sleeve 30 is fixedly connected with the container body 10.

As shown in fig. 2 and 4, the outer wall of the neck finish 11 is provided with a clamping groove 13, a connecting portion 22 connected to the neck finish 11 in a matching manner is arranged inside the cover body 20, and the inner wall of the connecting portion 22 is provided with a clamping tooth 23 matched to the clamping groove 13. The clamping teeth 23 and the clamping grooves 13 enable the cover body 20 and the container body 10 to be clamped in a rotating mode. In other embodiments of the present invention, the cap 20 is screwed with the container body 10; specifically, the outer wall of the neck finish 11 is provided with an external thread, and the inner wall of the connecting portion 22 is provided with an internal thread which is in threaded connection with the external thread.

As shown in fig. 3, the side wall of the cover body 20 is provided with 2 elastic pressing portions 21, and the 2 elastic pressing portions 21 are correspondingly arranged on two sides of the cover body 20. The upper end surface of the elastic pressing portion 21 is connected with the outer side surface of the cover body 20, a notch 25 is formed between the lower end surface and two side surfaces of the elastic pressing portion 21 and the outer side surface of the cover body 20, and the elastic pressing portion 21 has certain elasticity due to the notch 25. In some preferred embodiments of the present invention, an inwardly recessed depression 24 is formed on the surface of the cover body 20 corresponding to the elastic pressing portion 21. The concave portion 24 is provided to facilitate the user to apply force to press the elastic pressing portion 21.

As shown in fig. 4 and 5, a latch 211 is formed on a lower end surface of the elastic pressing portion 21, the latch 211 is provided with a guide surface 212 that is consistent with a rotation direction of the cover body 20 when being screwed in, and the guide surface 212 is an inclined plane or an arc surface; the latch 211 is provided with a blocking plane 213 at the other end thereof corresponding to the guide plane 212.

When the cap 20 is screwed in (the cap 20 and the container body 10 are screwed together), the stopper 33 slides along the guide surface 212 and presses the latch 211 inwards under the guidance of the guide surface 212, and the cap 20 is screwed in until the stopper 33 reaches the other end (one end of the stopper plane 213) of the latch 211, at which time, the cap 20 and the container body 10 are screwed in and the cap 20 cannot be screwed in; since the stopper 33 moves to one end of the stopping plane 213, the latch 211 is no longer pressed by the stopper 33 and rebounds outward, and when the cap body 10 is unscrewed, the latch 211 is stopped by the stopping plane 213 and cannot move forward continuously, thereby stopping the unscrewing of the cap body 20 and ensuring the stable capping of the cap body 10 and the container body 20. When the pressing panel 212 is pressed by hand, the pressing panel 212 is forced to drive the latch 211 to move inward, the latch 211 is no longer blocked by the blocking plane 213, and the cover 10 can be opened by rotating the cover 10.

As shown in fig. 9, the back surface of the container body 10 is provided with finger pressing positions 15, in this embodiment, the number of the finger pressing positions 15 is 2, when the cover body 10 needs to be opened or screwed, the container body 10 can be stably held by a hand as long as fingers are placed in any one of the finger pressing positions 15, so that slipping can be prevented, and the cover body 10 can be opened or screwed better.

The foregoing is considered as illustrative of the preferred embodiments of the invention and is not to be construed as limiting the invention in any way. Various equivalent changes and modifications can be made by those skilled in the art based on the above embodiments, and all equivalent changes and modifications within the scope of the claims should fall within the protection scope of the present invention.
