DETAILED DESCRIPTION

[0041] The following are specific embodiments of the invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figure 1 and Figure 2 As shown,

[0044] The present invention relates to a child-proof safety box comprising:

[0045] The pulp outer box 1 is rectangular in shape, with an inner box access opening 10 at one end. The pulp outer box 1 is made of pulp plant fiber material, which is environmentally friendly and degradable.

[0046] Snap holes 11 are respectively provided on both sides of the pulp outer box 1; the snap holes 11 are square holes.

[0047] The pulp inner box 2 is made of pulp plant fiber material, which is environmentally friendly and degradable.

[0048] The pulp inner box 2 enters the pulp outer box 1 from the inner box inlet and outlet opening 10, and both side edges of the pulp inner box 2 are respectively provided with convex clips 20 integrally formed with the pulp inner box 2, and the convex clips 20 are respectively buckled in the corresponding clip holes 11, and the wall thickness of the convex clips 20 is equal to the wall thickness of the pulp inner box 2.

[0049] Equal wall thickness can facilitate processing and manufacturing, and at the same time, can also produce a more beautiful inner box.

[0050] like Figure 3 As shown,

[0051] The two convex buckles 20 are deformed inwardly toward each other under the action of external force, thereby forcing the convex buckles 20 to disengage from the buckle holes 11 and push out the pulp inner box 2. The convex buckles 20 are buckled in the buckle holes 11, thereby realizing the mutual locking of the pulp outer box and the pulp inner box, and also preventing the food or medicine in the pulp inner box from being accidentally opened by a child and swallowed by mistake.

[0052] The structure is optimized, and the buckle holes 11 provided on one side of the pulp outer box 1 and the buckle holes 11 provided on the other side of the pulp outer box 1 are staggered in the front and back directions;

[0053] The protruding buckles 20 arranged on one side of the pulp inner box 2 and the protruding buckles 20 arranged on the other side of the pulp inner box 2 are staggered in front and back. When the pulp inner box 2 enters the pulp outer box 1, the protruding buckles 20 are buckled in the buckle holes 11.

[0054] The staggered distribution can form multiple blocking opening effects, including the asymmetrically positioned convex buckles 20 on the left and right sides and the inverted convex buckles 20 that are easy to enter and prevent from being pulled out. Once the pulp inner box is pushed in to the bottom, the convex buckles on the left and right sides will automatically buckle the pulp outer box, and the pulp inner box will be completely immersed in the outer box to prevent children from digging it out with their fingers or biting it with their teeth.

[0055] Furthermore, because the protruding buckles on the left and right sides are not in a straight line and are specially arranged at a greater distance, a child's small palm cannot press the buckles at the same time, thereby preventing the child from pulling it out.

[0056] like Figure 1 、 Figure 2 and Figure 4 As shown,

[0057] The outward convex buckle 20 is an outward convex buckle inclined inward from the upper opening of the pulp inner box 2 to the bottom thereof. An inclined groove 21 is formed on the inner side of the outward convex buckle 20 , with the inclined direction being consistent with the inclined direction of the outward convex buckle 20 .

[0058] The design of the inclined groove can realize the release of deformation pressure and free rebound after release, while the inclined protruding buckle 20 can be easily pressed inward to realize the rapid extraction of the pulp inner box.

[0059] The upper end of the protruding buckle 20 protrudes from the outer opening of the buckle hole 11, and the upper end of the inclined groove 21 is connected to the outside. This structure can achieve locking and prevent free falling. Secondly, the connection to the outside allows air to flow between the interior and the outside, which can prevent the difficulty of extracting the pulp inner box due to internal sealing.

[0060] Secondly, there is a gap between the inner top of the pulp outer box 1 and the upper open end face of the pulp inner box 2. Similarly, the gap can also prevent the inner pulp box from being difficult to be extracted due to sealing.

[0061] Specifically, the convex snap 20 includes a convex side edge portion 201 near one end of the inner box inlet and outlet opening 10, and the outer surface of the convex side edge portion 201 and the side of the pulp inner box 2 form an angle equal to 90°. The two are distributed vertically, which can facilitate the convex side edge portion 201 to be locked on the hole wall surface of the snap hole, because the outer surface of the convex side edge portion 201 will coincide with the hole wall surface of the snap hole, that is, locking is achieved.

[0062] And the convex side portion 202 away from the convex side portion 1 201, the outer surface of the convex side portion 202 and the side of the pulp inner box 2 form an angle 2 greater than 90°. In the optimized solution, the angle 2 here is greater than 90° and less than 180°.

[0063] The second convex side portion 202 is at such an angle, which can facilitate the insertion of the inner pulp box into the outer pulp box, that is, the second convex side portion 202 plays a guiding role during insertion.

[0064] The width of the convex side portion 201 gradually decreases from the upper opening of the pulp inner box 2 to its bottom, and the width of the convex side portion 202 gradually decreases from the upper opening of the pulp inner box 2 to its bottom. Through the structural design of the above width, the structural strength of the convex buckle can be improved without losing the deformability of the convex buckle. In addition, the above structure can not only achieve the self-locking effect, but also reduce the contact area between the convex side portion 201 and the corresponding hole wall of the buckle hole. The main function of reducing the contact area is to facilitate the subsequent extraction of the pulp inner box.

[0065] The width of the second convex side portion 202 gradually decreases from the upper opening of the pulp inner box 2 to its bottom, and the corresponding hole wall surface of the snap hole and the second convex side portion 202 form a linear contact, which can facilitate the extraction of the pulp outer shell from the pulp inner box.

[0066] It also includes an inclined portion 203, one side of the inclined portion 203 is connected to a side of the convex side portion 201 away from the pulp inner box 2, the other side of the inclined portion 203 is connected to a side of the convex side portion 202 away from the pulp inner box 2, and the bottom side of the inclined portion 203 is connected to the bottom side of the pulp inner box 2 to form the above-mentioned inclined groove 21, and the groove depth of the inclined groove 21 gradually decreases from the side of the convex side portion 1 201 to the side of the convex side portion 202. The unequal groove depth design can facilitate the release of deformation and the structural strength support during the deformation process, that is, the deformation of the convex side portion 1 201 is the largest, and the deformation of the convex side portion 202 is smaller than the deformation of the convex side portion 1 201.

[0067] Secondly, the depth of the inclined groove 21 is designed to facilitate the insertion of the inner pulp box into the outer pulp box, thereby achieving rapid assembly.

[0068] The outer surface of the inclined portion 203 is an arc-shaped concave surface, and the inner surface of the inclined portion 203 is an arc-shaped convex surface. This design makes it easy to press the convex buckle 20, that is, to prevent the pulp inner box from being unable to be smoothly pulled out due to inaccurate pressing position caused by the lack of a pressing point.

[0069] The inner surface of the first convex side portion 201 and the inner surface of the inclined portion 203 form an angle 3 less than 90°, and the inner surface of the second convex side portion 202 and the inner surface of the inclined portion 203 form an angle 4 greater than 90°.

[0070] like Figure 5 As shown,

[0071] The angle design can facilitate deformation and also facilitate resetting after deformation.

[0072] A closing portion 12 and an inner box ejection hole 13 are provided on the end of the pulp outer box 1 away from the inner box inlet and outlet opening 10. The inner box ejection hole 13 is a semicircular hole, which can facilitate the ejection of the pulp inner box, and the closing portion 12 can realize the ultimate positioning of the pulp inner box after insertion.

[0073] like Figure 1-5 As shown,

[0074] Secondly, the snap hole 11 is a square hole, the outer surface of the convex side portion 201 is consistent with the corresponding hole wall of the square hole, the outer surface of the convex side portion 202 and the side of the pulp inner box 2 form an angle of 120-170°, and the outer surface of the convex side portion 202 and the corresponding hole wall of the square hole are in line contact.

[0075] The inner and outer boxes are set to a tight fit. The protruding buckles on the inner pulp box will naturally protrude outward and form a tight and difficult-to-move state with the outer pulp box. Even if the buckles on both sides can be pressed in at the same time, the inner box must be pushed out with the help of fingers from the push-out hole at the rear end.

[0076] In addition, the second convex side portion 202 is an arc-shaped convex side portion 202 in transverse cross-section, the outer surface of the second convex side portion 202 is an arc-shaped convex surface, the inner surface of the second convex side portion 202 is an arc-shaped concave surface, and the arc-shaped concave surface and the arc-shaped convex surface are adapted to each other inside and outside.

[0077] One side of the second convex side portion 202 is connected to one side of the inclined portion, and the other side of the second convex side portion 202 is connected to the pulp inner box 2 via the arc-shaped inner recess 22. The design of the arc-shaped inner recess 22 facilitates the insertion and removal of the pulp inner box into the outer pulp box. At the same time, the second convex side portion 202 and the arc-shaped inner recess 22 are in different directions and are connected to each other, which can achieve deformation during pressing and elastic deformation recovery.

[0078] In an optimized solution, the pulp inner box 2 and the outer convex buckle 20 are integrally formed by pressing pulp. The pulp inner box 2 is processed by a pulp inner box mold, and of course, the pulp outer box 1 is processed by a pulp outer box mold.

[0079] An inner arc chamfer 23 is provided inside the pulp inner box 2, and an outer arc chamfer 24 is provided on the outer bottom of the pulp inner box 2, which is concentric with the inner arc chamfer 23. The outer arc chamfer 24 facilitates the insertion of the pulp inner box into the pulp outer box, while the design of the inner arc chamfer 23 facilitates the processing and manufacturing of the pulp inner box 2.

[0080] A method for manually opening a child-resistant safety box comprises the following steps:

[0081] S1. Preparation: When the inner pulp box 2 is located in the outer pulp box 1 and both are in a locked state, one hand presses down on the outer pulp box 1 from above, and the fingers of one hand respectively contact the outer surfaces of the protruding buckles 20 on both sides of the inner pulp box 2. The fingers of the other hand extend into the inner box ejection hole and contact the outer surface of the end of the inner pulp box near the inner box ejection hole.

[0082] S2. Pressing inwards: The fingers that were in contact with the outer surface of the convex buckle in step S1 apply pressure inwards. At this time, the two staggered convex buckles are deformed inwards under the action of the inward pressure and the convex buckles are released from the buckle holes.

[0083] S3. Push out. When the outer convex buckle in step S2 is disengaged from the buckle hole, the finger that was in contact with the outer surface of one end of the pulp inner box near the inner box pushing-out hole in step S1 applies pressure to the inner box inlet and outlet opening 10 of the pulp outer box, thereby partially pushing the pulp inner box out to the outside of the inlet and outlet opening or completely separating the pulp inner box from the pulp outer box.

[0084] Example 2

[0085] The convex buckle 20 includes a convex side edge portion 201 near one end of the inner box inlet and outlet opening 10, the outer surface of the convex side edge portion 201 and the side of the pulp inner box 2 form an angle 1 greater than 90 degrees, and a convex side edge portion 202 away from the convex side edge portion 201, the outer surface of the convex side edge portion 202 and the side of the pulp inner box 2 form an angle 2 greater than 90 degrees, the width of the convex side edge portion 201 gradually decreases from the upper opening of the pulp inner box 2 to its bottom, and the width of the convex side edge portion 202 gradually decreases from the upper opening of the pulp inner box 2 to its bottom, and also includes an inclined portion 203, one side of the inclined portion 203 is connected to the convex side edge portion 201. 01 is away from one side of the pulp inner box 2, the other side of the inclined portion 203 is connected to the side of the convex side portion 202 away from the pulp inner box 2, and the bottom side of the inclined portion 203 is connected to the bottom side of the pulp inner box 2 to form the above-mentioned inclined groove 21, and the groove depth of the inclined groove 21 gradually decreases from the side of the convex side portion 1 201 to the side of the convex side portion 202, the inner surface of the convex side portion 1 201 and the inner surface of the inclined portion 203 form an angle 3 less than 90°, the inner surface of the convex side portion 202 and the inner surface of the inclined portion 203 form an angle 4 greater than 90°, and the angle 1 is smaller than the angle 2.
