Example 1

As shown in Figures 1 and 2,

In the present invention, the safety box that can prevent opening by infants includes:

A rectangular paper pulp outer box (1) and an inner box inlet and outlet opening (10) provided at one end of the paper pulp outer box (1). The paper pulp outer box 1 is made of paper plant fiber material. Paper pulp outer box is environmentally friendly and degradable.

The two buckle holes are respectively arranged on both sides of the paper pulp outer box 1; The buckle hole 11 is a square hole.

Paper pulp inner box made of paper plant fiber material (2). Paper pulp inner box is environmentally friendly and degradable.

The paper pulp inner box (2) enters the paper pulp outer box (1) through the inner box inlet and outlet openings (10), and the buckles 20 protruding outwardly have buckle holes ( The wall thickness of the buckles 20 buckled one by one through 11) and projecting outwardly is equal to the wall thickness of the paper pulp inner box 2 .

The same wall thickness can make the inner box more beautiful while facilitating processing and manufacturing.

As shown in Figure 3,

The two buckles 20 protruding outward are reversely deformed inward by an external force to force the buckle 20 protruding outwardly to be separated from the buckle hole 11 and push the paper pulp inner box 2 . The buckle 20 protruding outward is buckled in the buckle hole 11 to achieve mutual locking of the paper pulp outer box and the paper pulp inner box, which means that the infant accidentally opens the paper pulp inner box and puts the paper pulp inner box into the box. Avoid eating foods or medicines.

Optimally, the buckle hole 11 provided on one edge of the paper pulp outer box 1 and the buckle hole 11 provided on the other side edge of the paper pulp outer box 1 are staggered back and forth;

The outwardly projecting buckle 20 provided on one edge of the pulp outer box 1 and the outwardly projecting buckle 20 provided on the other side edge of the pulp outer box 1 are alternately arranged back and forth. When the paper pulp inner box 2 enters the paper pulp outer box 1 , the buckle 20 protruding outward is buckled in the buckle hole 11 .

The distributed dislocation includes a buckle protruding outwardly positioned asymmetrically, and a plurality of outwardly protruding buckles 20, etc. having an edge that can prevent the outwardly protruding buckle 20 from being easily pushed and pulled out. It can form an open blocking effect. When the paper pulp inner box is pushed to the closed end, the left and right outwardly protruding buckles are automatically buckled into the paper pulp outer box, and the paper pulp inner box is completely and completely accommodated in the paper pulp outer box, which means that children's fingers Avoid digging or biting with your teeth.

In addition, the buckles projecting outwardly to the left and right are specially arranged at relatively long intervals rather than in a straight line. Since the hand of the infant is small, it is difficult to simultaneously press the buckle protruding outward, so that it can be prevented from being pulled out by the infant.

As shown in Figures 1, 2 and 4,

The buckle 20 protruding outward is inclined inwardly from the upper opening of the paper pulp inner box 2 toward the bottom, and on the inner side of the buckle 20 protruding outward, the inclination of the buckle 20 protruding outwardly An inclined groove 21 having an inclined direction coincident with the direction is formed.

The design of the inclined groove achieves the release of the deformation pressure and can rebound freely after release, while the inclined outwardly projecting buckle 20 facilitates pressing inward to quickly extract the paper pulp inner box.

The upper end of the buckle 20 protruding outward protrudes out of the outer opening of the buckle hole 11 , and the upper end of the inclined groove 21 communicates with the outside. This structure can achieve locking and prevent free spillage. Second, the communication with the outside enables air communication between the inside and the outside, thereby preventing the formation of a seal that makes it difficult to take out the paper pulp inner box.

Also, there is a gap between the inner top of the paper pulp outer box 1 and the upper open end face of the paper pulp inner box 2 . Similarly, the gap can prevent the formation of a seal that makes the paper pulp inner box difficult to remove.

Specifically, the outwardly projecting buckle 20 includes an outwardly convex side edge portion (I) 201 adjacent to one end of the inner box inlet and outlet openings 10 . An angle I of 90° is formed between the outer surface of the outwardly projecting side edge portion (I) 201 and the side edge of the paper pulp inner box 2 . The angle I is the outwardly projecting side edge portion (I) on the hole wall of the buckle hole ( I) facilitates the locking of the 201 .

The outwardly projecting side edge portion (II) 202 moves away from the outwardly projecting side edge portion (I) 201 . An angle II greater than 90° is formed between the outer surface of the outwardly projecting side edge portion (II) 202 and the side edge of the paper pulp inner box 2 . Preferably, the angle II is greater than 90° and less than 180°.

The outwardly projecting side edge portions (II) 202 are at an angle at which the paper pulp inner box can be easily inserted into the paper pulp outer box, that is, the outwardly projecting side edge portions (II) 202 are disposed at the time of insertion. serves as a guide.

The width of the outwardly projecting side edge portion (I) 201 gradually decreases from the upper opening of the paper pulp inner box 2 toward the bottom, and the width of the outwardly projecting side edge portion (II) 202 is It gradually decreases from the upper opening of the paper pulp inner box 2 to the bottom. This width structure of the design improves the structural strength of the outwardly projecting buckle without compromising the deformability of the outwardly projecting buckle. In addition, the above-described structure not only realizes the self-locking function but also reduces the contact area between the outwardly projecting side edge portion (I) 201 and the corresponding hole wall of the buckle hole. The main effect of reducing the contact area is that the box inside the paper pulp can be easily pulled out later.

The width of the outwardly projecting side edge portion (II) 202 gradually narrows from the upper opening of the paper pulp inner box 2 toward the bottom, and the corresponding hole wall of the buckle hole and the outwardly projecting side edge portion ( A contact line is formed between II) 202, which makes it easy to take out the paper pulp inner box from the paper pulp outer box.

The buckle protruding outwardly further includes an inclined portion 203 , and one edge of the inclined portion 203 is one edge of the outwardly projecting side edge portion (I) 201 away from the paper pulp inner box 2 . and the other side edge of the inclined portion 203 is connected with one edge of the side edge portion (II) 202 protruding outwardly away from the paper pulp inner box 2 . The bottom side of the inclined portion 203 is connected with the bottom side edge of the pulp inner box 2 to form the aforementioned inclined groove 21, and the groove depth of the inclined groove 21 is the side edge portion protruding outward ( It gradually decreases from I) (201) to the outwardly projecting side edge portion (II) (202). The unequal depth design of the groove depth facilitates release deformation during the deformation process and supports structural strength. That is, the deformation of the outwardly protruding side edge portion (I) 201 is the greatest, and the deformation of the outwardly protruding side edge portion (II) 202 is the outwardly protruding side edge portion (I) 201 . less than the deformation of

Further, the depth of the inclined groove 21 is designed to easily insert the paper pulp inner box into the paper pulp outer box to achieve quick assembly.

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 facilitates the pressing of the buckle 20 protruding outward, thereby preventing the incorrect pressing position caused by the absence of a pressing point and the failure to smoothly pull out the paper pulp inner box.

An angle III smaller than 90° is formed between the inner surface of the side edge portion 201 protruding outward and the inner surface of the inclined portion 203, and the side edge portion (II) 202 and the inclined portion protruding outwardly An angle IV greater than 90° is formed between the inner surfaces of 203 .

As shown in Figure 5,

The design of the angle facilitates deformation and facilitates restoration after deformation.

A closing portion 12 is arranged at one end of the paper pulp outer box 1 away from the inner box inlet and outlet openings 10 , and an inner box discharge hole 13 is arranged at the closed portion 12 so that the paper pulp interior This allows the box to come out easily. The closure portion 12 may limit the position of the box inside the paper pulp after insertion.

As shown in Figures 1 to 5,

Second, the buckle hole 11 is a square hole, and the outer surface of the outwardly projecting side edge portion (I) 201 coincides with the corresponding hole wall surface of the square hole. An angle II between 120° and 170° is formed between the outer surface of the outwardly projecting side edge portion (II) 202 and the side edge of the paper pulp inner box 2, and the outwardly projecting side edge portion (II) The outer surface of 202 is line contact with the corresponding hole wall surface of the square hole.
