[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Figure 1 An exploded view of an exemplary packaging structure 100 consistent with some embodiments of the present invention is shown. See also Figure 1 The packaging structure 100 includes a top cover 110, a base 120, and a child lock structure 130. The top cover includes a mating structure 111. The top cover 110 and the base 120 can be snapped together, for example, along... Figure 1As shown in the diagram, the top cover 110 and the base 120 are fastened together in the vertical direction, and the packaged item is accommodated between the top cover 110 and the base 120. In some embodiments, the base 120 includes a stepped structure, and the outer surface of the top cover 110 is flush with the stepped structure, which helps to improve the structural stability of the packaging structure 100.

[0023] The child lock structure 130 is connected to the base 120. For example, in some embodiments, the child lock structure 130 and the base 120 are fixedly connected by snap-fit, adhesive, interference fit, or other methods. Alternatively, in some embodiments, the child lock structure 130 and the base 120 can be detachably connected; for example, the base 120 includes a cavity 121, and the child lock structure 130 is inserted into the cavity 121 of the base 120. According to a preferred embodiment of the present invention, the child lock structure 130 is at least partially located inside the cavity 121, which can limit and protect the child lock structure 130, thereby improving the structural stability of the child lock structure 130.

[0024] See Figure 1 The child lock structure 130 includes a pressing part 131 and an elastic part 132. The pressing part 131 and the mating structure 111 are positioned correspondingly, and the pressing part 131 can engage with the mating structure 111 to lock the upper cover 110 and the base 120. In some embodiments, the pressing part 131 can penetrate the mating structure 111. For example, the mating structure 111 includes a second through hole penetrating the upper cover 110, and the pressing part 131 extends from the location of the second through hole to the outer side of the upper cover 110, engaging with the mating structure 111. In some embodiments, the pressing part 131 protrudes from the outer surface of the upper cover 110 at the location of the second through hole. Further, the protruding dimension of the pressing part 131 is approximately 1-4 mm, for example, 3 mm.

[0025] Alternatively, in some embodiments, the mating structure 111 includes structures such as countersunk holes, slots, and wedge-shaped surfaces provided on the inner side of the upper cover 110, and the pressing part 131 is located inside the upper cover 110 and abuts against the mating structure 111 to lock the upper cover 110 and the base 120.

[0026] With the top cover 110 and base 120 locked, the packaged item is locked inside the packaging structure 100 and cannot be removed, thus realizing the child lock function of the packaging structure 100 to prevent children from accidentally opening it and to protect children. When it is necessary to remove the packaged item inside the packaging structure 100, the pressing part 131 and the cooperating structure 111 are unlocked to open the packaging structure 100.

[0027] Specifically, in some embodiments, the pressing part 131 and the elastic part 132 are connected. When the pressing part 131 is pressed and moves relative to the mating structure 111, the elastic part 132 undergoes elastic deformation. For example, the pressing part 131 may be pressed back into the interior of the top cover 110 and disengage from the second through hole. Alternatively, in some embodiments, the pressing part 131 may disengage from structures such as countersunk holes, slots, or wedge-shaped surfaces to unlock the top cover 110 and the base 120, opening the packaging structure 100. After opening the packaging structure 100, the elastic part 132 rebounds, driving the pressing part 131 to penetrate the mating structure 111, or driving the pressing part 131 to abut against the mating structure 111, so that the top cover 110 and the base 120 are locked again. The elastic deformation of the elastic part 132 can support multiple opening and locking of the packaging structure 100, enabling reuse.

[0028] In this embodiment, the pressing part 131 and the elastic part 132 are integrally formed. In some embodiments, the pulp is integrally formed into a paper tray, constituting the pressing part 131 and the elastic part 132. Preferably, the pulp structure is adjusted to improve the elasticity of the paper tray and meet the elasticity requirements of the elastic part 132. Alternatively, in some embodiments, the pressing part 131 and the elastic part 132 can be made by folding cardboard blanks. According to a preferred embodiment of the present invention, the child lock structure 130, the top cover 110, and the base 120 are made of similar materials, which helps to reduce the types of materials, lower processing costs, and facilitate the recycling of the packaging structure 100 materials.

[0029] In this embodiment of the invention, the pressing part 131 in the child lock structure 130 and the cooperating structure 111 in the upper cover 110 cooperate with each other to lock and unlock the upper cover 110 and the base 120, reducing the risk of children accidentally opening the packaging structure 100 and protecting children. Meanwhile, the elastic part 132 allows the child lock structure 130 to be reused repeatedly. Furthermore, in this embodiment, the pressing part 131 and the elastic part 132 are integrally formed, resulting in a simple structure for the child lock structure 130, which simplifies the process and reduces material and processing costs. In a preferred embodiment, the child lock structure 130, the upper cover 110, and the base 120 are made of similar materials, such as paper, which helps reduce the difficulty of recycling the packaging structure 100 and improves environmental friendliness.

[0030] According to a preferred embodiment of the present invention, the child lock structure 130 further includes a first sidewall 133. See also... Figure 1 and Figure 2 A pressing part 131 is disposed on the first sidewall 133 and protrudes relative to the first sidewall 133. The first sidewall 133 is located on the outer periphery of the child lock structure 130, the first sidewall 133 surrounds the child lock structure 130, or the first sidewall 133 covers a portion of the outer periphery of the child lock structure 130.

[0031] In this embodiment, the first sidewall 133 is elastic, and part or all of the structure in the first sidewall 133 constitutes the elastic portion 132 described in the foregoing embodiments. Specifically, in some embodiments, the portion of the first sidewall 133 connected to the pressing portion 131 constitutes the elastic portion 132. Alternatively, in some embodiments, the entire first sidewall 133 constitutes the elastic portion 132. The elastic deformation mode of the elastic portion 132 will be described in detail in subsequent embodiments.

[0032] See Figure 1 In some embodiments, the first sidewall 133 is located on the outer periphery of the child lock structure 130, and the first sidewall 133 has a gap 134 within the outer periphery of the child lock structure 130. When the pressing part 131 is pressed and the elastic part 132 undergoes elastic deformation, the first sidewalls 133 move closer to each other at the location of the gap 134.

[0033] For example, in some embodiments, the gap 134 can limit the elastic deformation of the elastic portion 132. The portion of the first sidewall 133 connected to the pressing portion 131 moves toward the interior of the child lock structure 130 when the pressing portion 131 is pressed, and the pressing direction of the pressing portion 131 is approximately perpendicular to the end face of the gap 134. When the pressing portion 131 is pressed, the first sidewalls 133 move closer to each other at the location of the gap 134 until they abut. The gap 134 can limit the elastic deformation of the elastic portion 132, reducing the risk of structural damage. According to a preferred embodiment of the present invention, the width of the gap 134 within the outer periphery of the child lock structure 130 is approximately 3-6 mm, for example, 5 mm. Specifically, the width of the gap 134 can be determined based on the size of the pressing portion 131, the wall thickness of the top cover 110, and the material of the child lock structure 130.

[0034] In some embodiments, the portion of the first sidewall 133 connected to the pressing portion 131 moves toward the interior of the child lock structure 130 when the pressing portion 131 is pressed, and the pressing direction of the pressing portion 131 is approximately parallel to the end face of the gap 134. The elastic portion 132 generally forms a cantilever structure, and when the pressing portion 131 is pressed, the position where the elastic portion 132 is connected to the pressing portion 131 moves toward the interior of the child lock structure 130, and the first sidewalls 133 are misaligned at the position of the gap 134.

[0035] See Figure 1 and Figure 2 According to a preferred embodiment of the present invention, the base 120 includes a first through hole 122, and when the packaging structure 100 is closed, the first through hole 122 and the mating structure 111 are positioned correspondingly. For example, in some embodiments, the mating structure 111 includes a second through hole, and when the top cover 110 and the base 120 are fastened together, the first through hole 122 and the second through hole are aligned.

[0036] In this embodiment, the base 120 includes a cavity 121, and a first through hole 122 is located on and penetrates the side wall of the cavity 121. The child lock structure 130 is at least partially located inside the cavity 121. The pressing part 131 penetrates the first through hole 122 on the base 120 so that the pressing part 131 can engage with the mating structure 111. In this embodiment, the cavity 121 can limit and protect the child lock structure 130, and the first through hole 122 can guide the movement direction of the pressing part 131, which is beneficial to improving the structural stability of the child lock structure 130. Furthermore, in some embodiments, the first through hole 122 can position the pressing part 131 to prevent the child lock structure 130 from malfunctioning. When the pressing part 131 is pressed, the pressing part 131 disengages from the mating structure 111, and the pressing part 131 is confined inside the first through hole 122, reducing the risk that the pressing part 131 cannot be reset.

[0037] According to a preferred embodiment of the present invention, the first sidewall 133 of the child lock structure 130 is close to the inner surface of the cavity 121, or the first sidewall 133 is in contact with the inner surface of the cavity 121. In this embodiment, the inner surface of the cavity 121 can guide the direction of elastic deformation of the elastic part 132. At the same time, the structural strength of the cavity 121 can improve the impact and pressure resistance of the child lock structure 130, and improve the stability of the child lock structure 130.

[0038] Figure 3 A schematic diagram of the child lock structure 130 unfolded is shown. See also Figure 3 In some embodiments, the child lock structure 130 can be made by folding the same blank, in which the first sidewall 133 and the pressing part 131 are integrally formed. According to a preferred embodiment of the present invention, the child lock structure 130 is made by bending a paper tray formed from pulp, for example... Figure 3 A paper tray formed from pulp is shown, with its two ends bent relative to each other to form a first sidewall 133. Furthermore, the paper tray has a certain degree of elasticity, allowing the elastic part 132 to drive the pressing part 131 to spring back to its original position. Preferably, by adjusting the pulp material, the elasticity of the formed paper tray can be improved to meet different usage requirements.

[0039] See Figure 1 and Figure 3 In a preferred embodiment of the present invention, the child lock structure 130 further includes a top cover 135, which is partially connected to the first side wall 133, and the top cover 135 and the first side wall 133 are integrally formed.

[0040] See Figure 2According to a preferred embodiment of the present invention, the top cover 135 encloses the cavity 121 in the base 120 near the upper cover 110. The top cover 135 and the upper cover 110 together define a receiving space 112, in which the packaged item can be accommodated. In this embodiment, the top cover 135 can isolate the packaged item from the cavity 121 in the base 120, reducing the impact of the packaged item on the child lock structure 130 and improving the stability of the child lock structure 130.

[0041] Furthermore, in a preferred embodiment of this invention, the top cover 135 further includes a limiting groove 136. In this embodiment, the limiting groove 136 is recessed towards the base 120, and the position of the limiting groove 136 avoids the position of the pressing part 131. The shape of the limiting groove 136 matches the shape of the packaged item; for example, a portion of the packaged item can be inserted into the interior of the limiting groove 136. In this embodiment, the limiting groove 136 can limit the position of the packaged item in the receiving space 112, reducing the shaking of the packaged item, and isolating it from the pressing part 131, reducing the impact of the packaged item on the pressing part 131. In some embodiments, the inner surface of the top cover 110 may be provided with a filling structure that matches the shape of the packaged item, further defining the position of the packaged item in the receiving space 112.

[0042] Figure 4 and Figure 5 A schematic diagram of an exemplary packaging structure 100 consistent with other embodiments of the present invention is shown. See also Figure 4 and Figure 5 In this embodiment, the child lock structure 130 includes a first sidewall 133, which is located on the outer periphery of the child lock structure 130 and is continuous within the outer periphery of the child lock structure 130. For example, the first sidewall 133 is generally annular and can be fixed by bending the blank to connect the ends. In this embodiment, part or all of the structure of the first sidewall 133 constitutes the elastic part 132 described in the previous embodiment. Further, when the elastic part 132 undergoes elastic deformation, the first sidewall 133 is recessed towards the interior of the child lock structure 130. In some embodiments, the first sidewall 133 may also be broken or have a seam within the outer periphery of the child lock structure 130. Specifically, the child lock structure 130 is formed by bending a blank made of pulp, and the first sidewall 133 can be integrally formed as a circumferentially continuous structure, or it can be fixedly connected end to end after bending or at the seam position.

[0043] See Figure 4The child lock structure 130 has a cavity inside. When the pressing part 131 is pressed, the first side wall 133 is recessed toward the cavity inside the child lock structure 130. In this embodiment, the first side wall 133 is elastic and forms an elastic part 132. After the pressure acting on the pressing part 131 is released, the elastic part 132 rebounds so that the pressing part 131 is reset.

[0044] Furthermore, according to a preferred embodiment of the present invention, the child lock structure 130 or the base 120 has a limiting structure 123. See also Figure 5 The limiting structure 123 is disposed on the base 120. Specifically, in some embodiments, the base 120 includes a cavity 121, and the first sidewall 133 of the child lock structure 130 is close to or abuts the inner side of the cavity 121. The limiting structure 123 is located inside the cavity and within the cavity of the child lock structure 130. When the pressing part 131 is pressed and the first sidewall 133 is recessed toward the inside of the child lock structure 130, the limiting structure 123 can limit the recess stroke of the first sidewall 133 and limit the elastic deformation of the elastic part 132, thereby reducing the risk of damage or failure of the child lock structure 130. Preferably, in some embodiments, the limiting structure 123 can have a certain degree of elasticity. For example, the limiting structure 123 is connected to the bottom surface of the base 120 to form a cantilever structure.

[0045] Finally, it should be noted that the above descriptions are merely embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
