[0002] At present, the design of packaging boxes often fails to fully consider the issue of children's safety, especially for products containing chemical cleaning ingredients such as laundry detergent beads. Laundry detergent beads, as an innovative form of detergent, are wrapped in a water-soluble film on the outside and contain high-concentration detergent ingredients. The appearance design often combines soft texture and bright colors, and the shape is similar to candy or other edible snacks, which undoubtedly increases the appeal to children. It is very easy for children to mistake it for candy or food, which in turn leads to accidental ingestion, resulting in serious health risks.

[0003] In order to solve the above problems, the prior art has proposed a packaging box with a lock structure, which requires a relatively complex unlocking gesture to open the packaging box, effectively preventing children from accidentally opening it and obtaining the potentially harmful substances contained therein.

[0032] Reference Figure 1-Figure 9 An embodiment of the utility model provides a packaging box, comprising a box body 2 and a box cover 1 which are covered together, two elastic locking structures 3 are provided between the side walls of the box body 2 and the side walls of the box cover 1, and the two elastic locking structures 3 are arranged opposite to each other; wherein, two avoidance portions 4 are provided on the side walls of the box body 2 and / or the box cover 1 for respectively avoiding the two elastic locking structures 3.

[0033] Reference Figure 1 and Figure 2 as well as Figure 3Specifically, the box body 2 is a paper box structure, and the box body 2 can be in various shapes, such as a rectangular body, a circular cylinder, an elliptical cylinder, a triangular body, a polygonal body or other special-shaped box bodies 2. The shape of the cover body is adapted to the shape of the box body 2. For example, the box body 2 is a rectangular body, and the box cover 1 is a rectangular cover. The two elastic locking structures 3 are respectively located on the opposite sides of the packaging box, for example, on the two sides of the short side of the rectangular packaging box, and on the two sides of the diameter direction of the circular packaging box. The two elastic locking structures 3 are arranged opposite to each other, which is convenient for pressing with two fingers of one hand. The avoidance portion 4 can be a through hole or a notch. The avoidance portion 4 avoids the elastic locking structure 3, that is, the position of the avoidance portion 4 corresponds to the position of the elastic locking structure 3, so that the elastic locking structure 3 can be exposed, so that the fingers can pass through the avoidance portion 4 and directly press the elastic locking structure 3. The avoidance portion 4 can be provided on the side wall of the box cover 1, or on the side wall of the box body 2, or on the side walls of both the box body 2 and the box cover 1, depending on actual needs. The elastic locking structure 3 has a variety of specific structural forms, and no matter what form it is, as long as it can achieve elastic pressing to unlock and elastic resetting to lock, it is not limited here.

[0034] By implementing this embodiment, since the avoidance portion 4 is provided for the elastic locking structure 3, the finger of an adult can directly pass through the avoidance portion 4 to press the elastic locking structure 3. The elastic locking structure 3 is directly subjected to force, so a light press can produce a large ground deformation, and it is not necessary to apply a large pressing force to unlock. When unlocking, only the thumb and middle finger of one hand need to pass through the two avoidance portions 4 to press the two elastic locking structures 3 to unlock, so that the box cover 1 can be opened with one hand, the operation is simple, and the success rate of opening the box cover 1 at one time is high, ensuring that the children are restricted from opening the package without affecting the use of adults, and the adults can use it conveniently.

[0035] Reference Figure 4In one embodiment, the elastic locking structure 3 includes an elastic locking portion 31 and an undercut portion 32, one of which is disposed on the side wall of the box cover 1, and the other is disposed on the side wall of the box body 2, the elastic locking portion 31 and the undercut portion 32 are engaged and locked with each other, and the elastic locking portion 31 is exposed from the avoidance portion 4. Specifically, the elastic locking structure 3 is composed of two parts, including the elastic locking portion 31 and the undercut portion 32. When locked, the undercut portion 32 is on the top and the elastic locking portion 31 is on the bottom, and the upper side of the elastic locking portion 31 is engaged with the lower side of the undercut portion 32, so that the box body 2 and the box cover 1 are locked in the vertical direction, and the box body 2 cannot be opened upward. Specifically, the elastic locking portion 31 can be arranged on the side wall of the box cover 1 or on the side wall of the box body 2, and similarly, the undercut portion 32 can be arranged on the side wall of the box cover 1 or on the side wall of the box body 2. For example, the elastic locking portion 31 is arranged on the outer side wall of the box body 2, and the undercut portion 32 is arranged on the inner side wall of the box cover 1. For another example, the elastic locking portion 31 is arranged on the inner side wall of the box body 2, and the undercut portion 32 is arranged on the outer side wall of the box cover 1. Among them, the elastic locking portion 31 is a control component of the elastic locking structure 3, and the elastic locking portion 31 has a certain elasticity. When the elastic locking portion 31 is pressed and deformed, it is disengaged from the undercut portion 32 and unlocked, and when the elastic locking portion 31 is elastically reset, it resumes the engagement and locking with the undercut portion 32. Therefore, the avoidance portion 4 can avoid part of the elastic locking portion 31 of the elastic locking structure 3, and the elastic locking portion 31 is exposed from the avoidance portion 4, so that an adult's finger can pass through the avoidance portion 4 and press the elastic locking portion 31 to achieve unlocking.

[0036] Reference Figure 4 and Figure 5In one embodiment, the box cover 1 includes an outer cover 11 and an inner frame 12, wherein the outer cover 11 covers the top of the box body 2, the inner frame 12 is arranged on the side of the outer cover 11 facing the inside of the box body 2 and is accommodated in the inside of the box body 2, the elastic locking portion 31 is arranged on the outer frame wall of the inner frame 12, and the undercut portion 32 is arranged on the inner side wall of the box body 2. Specifically, the side of the outer cover 11 facing the inside of the box body 2 is the covering surface of the outer cover 11, the inner frame 12 is arranged on the covering surface of the outer cover 11, the upper end of the inner frame 12 is connected to the covering surface, and the shape of the inner frame 12 matches the shape of the box body 2. For example, the box body 2 is a rectangular box body 2, and the inner frame 12 is a rectangular frame. There is a gap between the side wall of the outer cover 11 and the frame wall of the inner frame 12. When the box cover 1 covers the box body 2, the side wall of the box body 2 is inserted into the gap, and the inner frame 12 is accommodated in the box body 2. From outside to inside, the side wall of the box cover 1 is at the outermost side, the side wall of the box body 2 is in the middle, and the frame wall of the inner frame 12 is at the innermost side. The inner side wall of the box body 2 is opposite to the outer frame wall of the inner frame 12, the undercut portion 32 is arranged on the inner side wall of the box body 2, and the elastic locking portion 31 is arranged on the outer frame wall of the inner frame 12, the undercut portion 32 is relatively close to the upper side, and the elastic locking portion 31 is relatively close to the lower side. Through the present embodiment, the elastic locking portion 31 is arranged on the inner frame 12, so that the inner frame 12, as a part of the outer cover 11, can be embedded in the box body 2 to form a tighter fit, and with the elastic locking portion 31, additional clamping force can be generated when the cover is closed, thereby enhancing the sealing effect of the package and preventing external dust and other pollutants from entering; and the structure of the inner frame 12 can provide additional support, so that the outer cover 11 is more stable in the closed state and reduces shaking during use; in addition, the design of the inner frame 12 can also protect the side wall of the outer cover 11 from direct wear or impact, thereby extending the service life of the packaging box. At the same time, suitable materials for the inner frame 12 can also increase impact resistance.

[0037] Reference Figure 5In this embodiment, the elastic locking portion 31 is formed by folding the lower edge of the inner frame 12 upwards, and the elastic locking portion 31 has an angle with the outer frame wall of the inner frame 12 in a natural state; when the elastic locking portion 31 is pressed against the outer frame wall of the inner frame 12, the elastic locking portion 31 is disengaged and unlocked from the undercut portion 32; when the elastic locking portion 31 is reset and rebounded, the elastic locking portion 31 and the undercut portion 32 are locked up and down. Specifically, the elastic locking portion 31 is an outer flange structure of the inner frame 12, folded upwards from the middle of the lower edge of the inner frame 12, and the elastic locking portion 31 is turned up to the outer frame wall of the inner frame 12. Since the material of the paper box is relatively soft, the elastic locking part 31 has a certain elasticity, so it is difficult for the elastic locking part 31 to be folded to fit closely with the outer frame wall of the inner frame 12. The elastic locking part 31 and the outer frame wall of the inner frame 12 will form an angle. When the angle is zero, the elastic locking part 31 is attached to the outer frame wall of the inner frame 12. The range of the angle can be, for example, zero to ten degrees, which is not limited here. When locking, the finger passes through the avoidance part 4 to press the elastic locking part 31, and the elastic locking part 31 is deformed to fit the outer frame wall of the inner frame 12, the angle becomes zero, and the elastic locking part 31 is staggered with the undercut part 32, thereby unlocking. When the finger is released, the elastic locking part 31 recovers the deformation, the angle increases, and the elastic locking part 31 and the undercut part 32 are engaged with each other, thereby locking.

[0038] Continue to refer to Figure 5 In a specific implementation, the elastic locking portion 31 includes a buckling body 311 and a pressing body 312. The lower side of the buckling body 311 is connected to the lower edge of the inner frame 12, and the middle of the upper side of the buckling body 311 is connected to the pressing body 312. The pressing body 312 extends in a direction away from the lower edge of the inner frame 12, and the pressing body 312 is exposed in the avoidance portion 4. Specifically, the elastic locking portion 31 is a convex structure as a whole, and the convex part is the pressing body 312. Since the elastic locking portion 31 is formed by folding upward, and the pressing body 312 extends upward from the middle of the buckling body 311, the pressing body 312 is closer to the upper surface of the box cover 1. In this way, the fingers do not need to extend too far down, and the fingers can easily press the pressing body 312, thereby improving the convenience of opening the box.

[0039] Reference Figure 6 and Figure 7In a specific implementation, the inverted portion 32 includes a first inverted body 321 and a second inverted body 322, and the first inverted body 321 and the second inverted body 322 are arranged at intervals on the inner side wall of the box body 2; when the elastic locking portion 31 and the inverted portion 32 are locked up and down, the first inverted body 321 and the second inverted body 322 are respectively located on both sides of the pressing body 312, and the lower sides of the first inverted body 321 and the second inverted body 322 are respectively engaged with the upper side of the snap-fit ​​body 311. Specifically, since the elastic locking portion 31 is provided with a pressing body 312, the pressing body 312 separates the snap-fit ​​body 311, so that the upper side of the snap-fit ​​body 311 is divided into two left and right sections. In order to ensure the reliability of locking, the first inverted body 321 and the second inverted body 322 are provided in this embodiment, and the first inverted body 321 and the second inverted body 322 are arranged at intervals and located on both sides of the avoidance portion 4. When the box body 2 and the box cover 1 are locked together, the first inverted body 321 and the second inverted body 322 are located on both sides of the pressing body 312, the lower side of the first inverted body 321 abuts against the upper side of the left section of the buckling body 311, and the lower side of the second inverted body 322 abuts against the upper side of the right section of the buckling body 311. By providing two inverted bodies to engage with the buckling part, more points of engagement are added, and the reliability of locking is improved.

[0040] contrast Figure 5 and Figure 6 / Figure 7In one embodiment, the side wall of the outer cover 11 is arranged around the inner frame 12, and the inner side wall of the outer cover 11 abuts against the elastic locking portion 31 to limit the angle between the elastic locking portion 31 and the outer frame wall of the inner frame 12, and the avoidance portion 4 is provided on the outer cover 11 and the box body 2. Specifically, since the elastic locking portion 31 is formed by folding upward, when the box cover 1 is opened, the elastic locking portion 31 is exposed, and it is easy to accidentally touch the elastic locking portion 31 to turn it outward. If the elastic locking portion 31 is turned outward too much, it is necessary to fold the elastic locking portion 31 back before use, which is not beautiful. After long-term use, its elasticity is easy to fail. Therefore, in order to prevent the elastic locking portion 31 from turning outward, in this embodiment, the side wall of the outer cover 11 is extended downward to be flush with the inner frame 12 body or lower than the lower edge of the inner frame 12 body, so that the side wall of the outer cover 11 surrounds the inner frame 12 and wraps the outer periphery of the entire inner frame 12. Since the side wall of the outer cover 11 wraps the entire inner frame 12, it is necessary to provide the avoidance portion 4 on the side wall of the outer cover 11 and the box body 2 so that the fingers can touch the elastic locking portion 31. In this way, the outward turning angle of the elastic locking portion 31 on the inner frame 12 will be limited by the side wall of the outer cover 11, the inner side wall of the outer cover 11 abuts against the elastic locking portion 31, and the elastic locking portion 31 is limited between the inner side wall of the outer cover 11 and the outer frame wall of the inner frame 12, and the angle between the elastic locking portion 31 and the outer frame wall of the inner frame 12 is fixed. In this way, the outward turning of the elastic locking portion 31 is avoided, the reliability of locking is improved, and the service life is extended.

[0041] Reference Figure 8 In one embodiment, a frame surface 13 is provided on a side of the inner frame 12 close to the outer cover 11, and a bonding edge 131 is formed on the frame surface 13 extending toward the outer side of the inner frame 12, and the bonding edge 131 is bonded to a side of the outer cover 11 facing the inside of the box body 2. Specifically, in order to realize the assembly of the inner frame 12 and the outer cover 11, the inner frame 12 is designed to be an integrated structure, and the upper end of the inner frame 12 has a frame surface 13, and a plurality of bonding edges 131 extending toward the outer side of the inner frame 12 are cut out of the edge of the frame surface 13, and the frame surface 13 is bonded to the covering surface of the outer cover 11 through the bonding edge 131, thereby realizing the assembly of the inner frame 12 and the outer cover 11.

[0042] In another embodiment, an adhesive strip (not shown in the figure) is provided between the outer frame wall of the inner frame 12 and the inner wall of the outer cover 11, and the outer frame wall of the inner frame 12 and the inner wall of the outer cover 11 are both bonded to the adhesive strip. Specifically, in order to realize the assembly of the inner frame 12 and the outer cover 11, an adhesive strip can also be used for bonding. During assembly, both sides of the adhesive strip are coated with glue, one side of the adhesive strip is bonded to the inner wall of the outer cover 11, and the other side of the adhesive strip is bonded to the outer frame wall of the inner frame 12, thereby realizing the assembly of the inner frame 12 and the outer cover 11.

[0043] Reference Fig. 9 In one embodiment, a limiting portion 14 is provided in the inner frame 12, and the end surface of the limiting portion 14 and the elastic locking portion 31 are arranged back to back relative to the inner frame 12, and the end surface of the limiting portion 14 abuts against the inner frame wall of the inner frame 12. Specifically, after long-term use, the elastic locking portion 31 is pressed too many times, the inner frame 12 is deformed, and the elastic locking portion 31 is easily invalidated, in order to extend its service life. In this embodiment, a limiting portion 14 is provided in the inner frame 12, and the limiting portion 14 can be provided on the frame surface 13 of the inner frame 12, and can also be provided on the covering surface of the outer cover 11. The limiting portion 14 can be a triangular structure or a rectangular structure, which is not limited here. The elastic locking portion 31 will cause the inner frame 12 to deform when pressed. The elastic locking portion 31 is pressed toward the inner side of the inner frame 12. Therefore, the limiting portion 14 is arranged in the inner frame 12, and the end face of the limiting portion 14 is used to support the position of the inner frame 12 opposite to the elastic locking portion 31. In this way, when the elastic locking portion 31 is pressed toward the inner side of the inner frame 12 to cause the inner frame 12 to deform, the end face of the limiting portion 14 can support the inner frame 12, thereby reducing the deformation degree of the inner frame 12, thereby avoiding failure of the elastic locking portion 31.

[0044] In one embodiment, the distance between the two elastic locking structures 3 is 90mm-110mm. Specifically, according to the comparison of the palm size of adults and children, the spacing between the two elastic locking structures 3 is designed to be between 90mm and 110mm. For example, the spacing between the two elastic locking structures 3 is 90mm, the spacing between the two elastic locking structures 3 is 110mm, and the spacing between the two elastic locking structures 3 is 100mm. Of course, it is understandable that it can also be other numerical ranges. The spacing between the two elastic locking structures 3 needs to be moderate. If it is too large, it is not convenient for adults to press with one hand, and if it is too small, there is a hidden danger of opening for children. Therefore, through the above-mentioned distance range, it is ensured that adults can press the elastic locking structures 3 on both sides of the box cover 1 with one hand at the same time, grab the box body with one hand, and open the packaging box at one time; while children's hands are small and cannot press the elastic locking structures 3 on both sides at the same time, thereby ensuring that children cannot open the packaging box.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
