Description

Spring storage and access packaging container unit, container and storage and access method

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority from and is based on a Chinese patent application filed with the State Intellectual Property Office of China on September 21, 2023, with application number: 202311221404.9, and the name of the invention: "A spring storage and access packaging container unit, container and method". The content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0003] The present application relates to the field of spring packaging, and in particular to a spring storage and retrieval packaging container unit, container and method. Background Art

[0004] Spring packaging boxes on the market primarily feature compartmentalized boxes. For example, CN207684180U uses a support frame and partitions to divide the space into four quadrants, each housing a spring. The partitions and baffles increase the space required for spring packaging. CN201999334U, on the other hand, places multiple springs end-to-end on a long paper strip before packaging. This direct contact between the springs reduces wasted packaging space. However, this solution only folds back the ends of the paper strip to prevent the springs from detaching. This leaves the springs naturally long, and thus fails to effectively save packaging space.

[0005] Combining the two solutions above, we can place multiple springs end-to-end in a long, rectangular packaging container and compress them, effectively saving packaging space. However, traditional packaging tubes are often closed at one end and open at the other, or open at both ends. The open end requires a lid to close. If a spring is placed in a packaging container and compressed, the compressed spring will tend to return to its original length and pop out of the open end of the packaging tube, requiring additional pressure to close the tube. The same is true when opening the lid to retrieve items: the compressed spring will pop out directly from the open end, making it impossible to remove them in a controlled manner. Therefore, traditional long, rectangular packaging containers are not suitable for compressed storage and retrieval of springs.

[0006] Summary of the Invention

[0007] The main technical problem to be solved by the present application is that the long strip packaging container is not suitable for compressing the spring to put it in and take it out.

[0008] In order to solve the above technical problems, the present application improves the structure of the packaging container and, in the first aspect, provides a spring storage and access packaging container unit. The box body of the spring storage and access packaging container unit is long and narrow, and the bottom of the box body is an opening. The cross-section of the box body is slightly larger than the cross-section of the spring. A spring removal opening is provided on the side surface of the top end of the box body, and an end cover or a one-way paddle is provided on the bottom of the box body.

[0009] The above technical solution sets the spring removal opening of the spring storage and packaging container unit on the top side of the box body. The direction of the spring's elastic force is mainly upward or downward along the long axis of the box body, and the path for removing the spring from the spring removal opening is perpendicular to the long axis of the box body. Therefore, when the spring removal opening is in the open state, the spring is not easily ejected by the elastic force, and the spring can be removed in a controlled manner.

[0010] Furthermore, the bottom surface of the box body is provided with a one-way pick extending toward the inside of the box body, and one end of the one-way pick (200) can be rotated toward or away from the box wall. In the above scheme, when the spring is pressed into the box body from the bottom surface of the box body, the one-way pick undergoes forward deformation and sticks to the box wall. When the spring leaves the one-way pick, the one-way pick returns to its original shape and prevents the spring in the box body from leaving the box body through the spring removal opening.

[0011] Furthermore, the one-way paddle forms an acute angle with the box body, and when the spring enters the box body, the swing angle of the one-way paddle decreases.

[0012] Furthermore, the one-way paddle is integrally formed with the box body. In the above solution, the spring-loaded packaging container unit has the advantage of a simple structure.

[0013] Furthermore, one end of the one-way paddle, which is close to the bottom surface of the box body, extends to form a connecting wall, which is connected to the outer wall of the bottom side of the box body. The connection methods of the connecting wall and the outer wall of the bottom side of the box body mentioned in the above technical solution include but are not limited to snap connection, plug connection, thread connection, sleeve connection and bonding.

[0014] Furthermore, the connecting walls of the multiple one-way paddles are connected to form an annular structure, which is sleeved onto the outer wall of the bottom side of the box body and has an interference fit with the bottom side of the box body. In this technical solution, the abutment of the annular structure with the outer wall of the bottom side of the box body further prevents the one-way paddles from reverse deformation, thereby providing a high level of structural reliability. In addition, the position of the multiple one-way paddles and the annular structure is relatively fixed, and the annular structure has an interference fit with the bottom side of the box body, which has the advantages of easy installation, simple structure and stability.

[0015] Furthermore, the box body is provided with a removal cover that covers the spring removal opening when the spring removal opening is closed. In the above technical solution, the removal cover prevents the spring from leaving the box body through the spring removal opening when it is not needed. The removal cover can be integrally formed with the box body, or it can be a cover plate mounted on the box body via a slide rail, or a cylinder mounted on the outer wall of the top side of the box body.

[0016] In a second aspect, the present application also provides a spring storage and packaging container comprising at least two of the aforementioned spring storage and packaging container units. This spring storage and packaging container offers the advantage of enabling controlled insertion and removal of springs. Furthermore, when a large number of springs are present, placing the springs in multiple, individually movable spring storage and packaging container units effectively reduces the weight of each spring storage and packaging container unit, making storage and handling more convenient. Furthermore, the multiple spring storage and packaging container units can be assembled or disassembled.

[0017] On the third aspect, the present application provides another spring storage and access packaging container unit, the box body of the spring storage and access packaging container unit is prismatic, the bottom surface of the box body is an opening, the cross-section of the box body is slightly larger than the cross-section of the spring, and the top side of the box body extends to form two opposite extension surfaces, the two extension surfaces are connected to form a second top surface and a spring removal opening is formed on the adjacent surfaces of the two extension surfaces, and the bottom surface of the box body is provided with an end cover or a one-way paddle.

[0018] Furthermore, the top side surface of the box body adjacent to the extended surface extends upward to form two first top surfaces, and the two first top surfaces can connect and close the top surface of the box body.

[0019] Furthermore, the second top surface can be separated into two connecting surfaces.

[0020] Furthermore, a one-way paddle extending toward the interior of the box body is provided at the bottom end of the box body. The one-way paddle can only deform in the forward direction and cannot deform in the reverse direction. In the above solution, when the spring is pressed into the box body from the bottom end, the one-way paddle deforms in the forward direction. When the spring leaves the one-way paddle, the one-way paddle returns to its original shape and prevents the spring in the box body from leaving the box body through the spring removal opening.

[0021] Furthermore, the one-way paddle forms an acute angle with the box body, and when the spring enters the box body, the swing angle of the one-way paddle decreases.

[0022] Furthermore, the one-way paddle is integrally formed with the box body.

[0023] Furthermore, one end of the one-way paddle, which is close to the bottom surface of the box body, extends to form a connecting wall, which is connected to the outer wall of the bottom end side of the outer side surface of the box body. The connection methods of the connecting wall and the outer wall of the bottom end side of the box body mentioned in the above technical solution include but are not limited to snap connection, plug connection, thread connection, sleeve connection and bonding.

[0024] Furthermore, the connecting walls of the multiple one-way paddles are connected to form an annular structure, which is sleeved onto the outer wall of the bottom side of the box body and has an interference fit with the bottom side of the box body. In this technical solution, the abutment of the annular structure with the outer wall of the bottom side of the box body further prevents the one-way paddles from reverse deformation, thereby providing a high level of structural reliability. In addition, the position of the multiple one-way paddles and the annular structure is relatively fixed, and the annular structure has an interference fit with the bottom side of the box body, which has the advantages of easy installation, simple structure and stability.

[0025] In a fourth aspect, the present application provides a spring storage and packaging container comprising at least two of the aforementioned spring storage and packaging container units. This spring storage and packaging container has the advantage of enabling controlled insertion and removal of springs. Furthermore, when a large number of springs are present, placing the springs in multiple, individually movable spring storage and packaging container units effectively reduces the weight of each spring storage and packaging container unit, making storage and handling more convenient. Furthermore, the multiple spring storage and packaging container units can be assembled and disassembled.

[0026] In a fifth aspect, the present application provides a spring access packaging method, comprising a spring access packaging container unit, wherein the box body of the spring access packaging container unit is in an elongated shape, the bottom surface of the box body is an opening, the bottom surface of the box body is provided with a one-way paddle extending toward the interior of the box body, and a spring removal opening is provided on the side surface of the top of the box body;

[0027] When the springs need to be put in, insert them from the bottom of the box body, and the springs are loaded in a single row in sequence;

[0028] When the spring needs to be taken out, the spring taking-out opening is opened and the spring at the top is taken out. The spring at the top is pushed to the spring taking-out opening by the elastic force, and then the spring is taken out from the spring taking-out opening.

[0029] In a sixth aspect, the present application provides another spring access packaging method, comprising a spring access packaging container unit, wherein the box body of the spring access packaging container unit is prismatic, the bottom surface of the box body is an opening, the bottom surface of the box body is provided with a one-way paddle extending inwardly of the box body, and two opposing extended surfaces are extended from the top side of the box body, the extended surfaces are connected to form a second top surface, and a spring removal opening is formed on adjacent surfaces of the two extended surfaces;

[0030] When the spring needs to be placed, bend the extended surface into the box body and close the top surface of the box body, insert the spring from the bottom surface of the box body, and the springs are installed in a single row in sequence;

[0031] When the spring needs to be taken out, the two extended surfaces are unfolded to form a second top surface, and the adjacent surfaces of the extended surfaces form a spring taking-out opening, and the spring is taken out from the spring taking-out opening.

[0032] Compared with the existing technology, this application has the following beneficial effects:

[0033] 1. By forming a spring removal opening on the top side wall of the box body or forming a spring removal opening on the adjacent surface of the extended surface, the path of the spring leaving the spring storage and access packaging container unit from the spring removal opening is perpendicular to the long axis of the spring storage and access packaging container unit, and the spring is not easily ejected by elastic force, thereby achieving controllable removal of the spring.

[0034] 2. In some possible implementations, a one-way paddle is provided on the bottom of the box body, which can prevent the spring from popping out from the bottom of the box body when the spring is inserted, thereby achieving controllable insertion of the spring.

DETAILED DESCRIPTION

[0053] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0054] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0055] In this application, "slightly larger" means that the cross-section of the box body 100 can cover the maximum cross-section of the spring 500 and the cross-sectional area of ​​the box body 100 is no more than 30% of the maximum cross-sectional area of ​​the spring 500. If the cross-sectional area of ​​the box body 100 is greater than 30% of the maximum cross-sectional area of ​​the spring 500, the spring 500 may bend or tilt away from the longitudinal axis of the box body 100 after entering the box body 100, causing the two springs 500 to become laterally blocked within the box body 100 and unable to move from the bottom to the top of the box body under the action of elastic force. Preferably, the cross-sectional area of ​​the box body is greater than 10% of the cross-sectional area of ​​the spring.

[0056] In this application, “upper” as a directional word refers to the direction along the long axis of the box body 100 from the bottom surface 110 of the box body to the top surface 130 of the box body, and “lower” as a directional word refers to the direction along the long axis of the box body 100 from the top surface 130 of the box body to the bottom surface 110 of the box body.

[0057] Example 1

[0058] The box body 100 of the spring storage and access packaging container unit provided in Example 1 is an integrally molded plastic part. Figure 1 is a three-dimensional structural diagram of the spring storage and access packaging container unit provided in Example 1. As shown in the figure, the box body 100 of the spring storage and access packaging container unit is a quadrangular prism, the top surface of the box body is closed, and a spring removal opening 141 is provided on the top side surface 140 of the box body, and a removal cover 142 is provided on the spring removal opening 141.

[0059] FIG2 is a longitudinal cross-sectional view of the spring-loaded packaging container unit provided in Example 1, and FIG3 is a bottom view of the spring-loaded packaging container unit provided in Example 1. As can be seen from the figure, the inner wall of the bottom side surface 120 of the box body is provided with four one-way paddles 200. One end of the one-way paddles 200, which is close to the bottom surface 110 of the box body, extends to form a connecting wall 210. The connecting wall 210 is connected to the inner wall of the bottom side surface 120 of the box body (in other possible implementations, the connecting wall 210 can also be connected to the outer wall of the side surface of the bottom side 120 of the box body). As can be seen from FIG2, the one-way paddles 200 extend into the interior of the box body 100 and form an acute angle with the box body 100, and can approach the box wall direction of the top surface 130 of the box body.

[0060] Example 2

[0061] The following is a second embodiment of the spring storage and retrieval process of the spring storage and retrieval packaging container of the first embodiment, which will be described in conjunction with Figures 4 to 8.

[0062] Figures 4 to 6 are schematic diagrams of the process of placing the spring 500 into the container. When the spring 500 needs to be placed:

[0063] The spring 500 is inserted from the bottom surface 110 of the box body. After the spring 500 contacts the one-way pick 200, it squeezes the one-way pick 200 to cause it to deform in a forward direction with a smaller acute angle or expand toward the wall end of the box body. Then, the spring 500 leaves the one-way pick 200 and slides toward the top surface 130 of the box body.

[0064] Multiple springs 500 are connected end to end and installed in a single row. As the number of springs 500 gradually increases, the springs 500 begin to be compressed. The spring 500 at the bottom of the box body 100 abuts against the one-way paddle 200. Since the one-way paddle 200 is squeezed in the reverse direction, the paddle rotates away from the side wall of the box body, shrinking the entrance, and the spring 500 cannot leave the box body 100 from the bottom surface 110 of the box body.

[0065] FIG7-FIG8 are schematic diagrams showing the process of removing the spring 500 from the container. When the spring 500 needs to be removed:

[0066] Pull out the box cover 142 to expose the side opening 141 of the box body, and take out the spring 500 at the top from the spring removal opening 141. After that, although the number of springs 500 decreases, the springs 500 are gradually released, and the top spring 500 is pushed to the spring removal opening 141 under the action of elastic force. Repeat the above operation until all the required springs 500 are taken out.

[0067] Example 3

[0068] Referring to Figures 9 to 11, Figure 9 is a three-dimensional structural diagram of the spring storage and access packaging container unit provided in Example 3. The box body 100 of the spring storage and access packaging container unit is cylindrical, with a closed top surface 130. A spring removal opening 141 is provided on the top side surface 140 of the box body, and the spring removal opening 141 is covered with a removal cover 142. Four one-way paddles 200 are provided on the bottom surface 110 of the box body (see Figure 10). The one-way paddles 200 extend from one end near the bottom surface 110 of the box body to form a connecting wall 210. The four one-way paddles 200 are connected to the connecting wall 210 and can be integrated with the box body or form an annular separate structural component that is sleeved on the outer wall of the bottom side surface 120 of the box body.

[0069] Figure 10 is a longitudinal cross-sectional view of the spring storage and access packaging container unit provided in Example 3, and Figure 11 is a bottom view of the spring storage and access packaging container unit provided in Example 3. It can be seen from the figure that the one-way paddle 200 extends into the interior of the box body 100 and forms an acute angle with the box body 100. The multiple one-way paddles 200 of this embodiment are spaced equally and do not interfere with each other. Under this arrangement, when the one-way paddle 200 is subjected to pressure, the force on the one-way paddle 200 and the annular structure is relatively uniform, which is beneficial to improving the durability of the one-way paddle 200.

[0070] Example 4

[0071] Figure 12 is a three-dimensional structural diagram of the spring storage and retrieval packaging container unit provided in Example 4. The box body 100 of the spring storage and retrieval packaging container unit is an octagonal prism, the top surface 130 of the box body is closed, and a spring removal opening 141 is provided on the top side surface 140 of the box body. The spring removal opening 141 is covered with a removal cover 142, and the removal cover 142 is directly opened on the box body 100 and is integrally formed with the box body 100.

[0072] FIG13 is a longitudinal cross-sectional view of a spring-loaded packaging container unit according to a fourth embodiment, and FIG14 is a bottom view of the spring-loaded packaging container unit according to a fourth embodiment. As can be seen from the figure, eight one-way paddles 200 are provided on the bottom side 120 of the box body. The one-way paddles 200 extend from one end near the bottom 110 of the box body to form a connecting wall 210. The one-way paddles 200 extend from one end near the bottom 110 of the box body to form a connecting wall 210. The connecting wall 210 is bonded to the inner wall of the bottom side 120 of the box body. The one-way paddles 200 extend into the interior of the box body 100 and form an acute angle with the box body 100. The eight one-way paddles 200 of this embodiment do not interfere with each other.

[0073] Example 5

[0074] FIG15 is a schematic diagram of the unfolding of the spring storage and access packaging container unit provided in Example 5. As shown in the figure, the spring storage and access packaging container unit is a cardboard after unfolding (in other possible implementations, the spring storage and access packaging container unit can also be a plastic sheet). Adhesive surfaces are provided on both sides of the cardboard. By adhering the two adhesive surfaces to each other, a spring strip storage and access packaging container unit can be obtained. Among them, the box body 100 of the spring storage and access packaging container unit of Example 5 is a quadrangular prism, the bottom surface of the box body is an opening (not shown in the figure), and the top side surface 140 of the box body extends to form two opposing extension surfaces 300. The ends of the two extension surfaces 300 away from the box body 100 are provided with connecting surfaces 311. The two connecting surfaces 311 can be connected to the second top surface 310 through an insert and form a spring removal opening 141 below the adjacent surfaces of the two connecting surfaces 311 (the second top surface 310 and the spring removal opening 141 are not shown in the figure, please refer to FIG18). Two opposite first top surfaces 400 are further extended and formed above the top side surface 140 of the box body and adjacent to the extension surface 300 . The two first top surfaces 400 can be connected by inserting pieces or other means.

[0075] Four one-way paddles 200 are provided on the bottom side 120 of the box body (in FIG. 15 , the one-way paddles are in an unfolded state and not yet extended into the box body). One end of the one-way paddles 200, near the bottom side 110 of the box body, extends to form a connecting wall 210 (not shown; see FIG. 16 ). A limiting latch 211 is provided on the connecting wall 210, and a slot 121 corresponding to the limiting latch 211 is provided on the bottom side 120 of the box body. The one-way paddles 200 are connected to the bottom side 120 of the box body through the matching limiting latch 211 and the slot 121. A fold 600 is provided on the extension surface 300 and between the extension surface 300 and the top side 140 of the box body. The extension surface 300 can be bent inwardly of the box body 100 along the fold 600.

[0076] Figure 16 is a longitudinal cross-sectional view of the spring storage and access packaging container unit provided in Example 5 when the extension surface 300 is in a bent state. Figure 17 is an enlarged view of part A in Figure 16. At this time, the one-way paddle 200 extends into the interior of the box body 100 and forms an acute angle with the box body 100. The extension surface 300 is bent inside the box body 100, and the top surface 130 of the box body is closed by the first top surface 400.

[0077] 18 is a longitudinal cross-sectional view of the spring storage and retrieval packaging container unit provided in the fifth embodiment when the extension surface 300 is in an expanded state. The first top surface is opened, and the extension surface 300 is expanded to form a second top surface 310 , exposing the spring removal opening 141 .

[0078] Example 6

[0079] The following describes the spring storage and retrieval packaging container unit of the fifth embodiment in conjunction with Figures 19 to 24 to illustrate the spring storage and packaging method and the spring retrieval process, which is the sixth embodiment.

[0080] FIG19-FIG20 are schematic diagrams showing the process of placing the spring 500 into the container. When placing the spring 500:

[0081] The extension surface 300 is bent inwardly of the box body 100 and closes the box body top surface 130 . At this time, the box body top surface 130 is in a closed state. Therefore, the spring 500 cannot leave the box body 100 from the box body top surface 130 after entering the box body 100 .

[0082] The spring 500 is inserted from the bottom surface 110 of the box body. After the spring 500 contacts the one-way paddle 200, it squeezes the one-way paddle 200 to cause it to deform in a forward direction with a smaller acute angle. Then, the spring 500 leaves the one-way paddle 200 and slides toward the side of the top surface 130 of the box body.

[0083] Multiple springs 500 are installed in a single row in sequence. As the number of springs 500 gradually increases, the springs 500 begin to be compressed, and the spring 500 at the bottom of the box body 100 abuts against the one-way paddle 200. Since the opening at the end of the one-way paddle 200 is reversed and narrowed, the spring 500 cannot leave the box body 100 from the bottom surface 110 of the box body.

[0084] Figures 21 to 23 are schematic diagrams showing the process of placing the spring 500 into the container and removing the spring 500:

[0085] The two connected first top surfaces 400 are separated, the expansion surface 300 is unfolded, and the connecting surface 311 forms the second top surface 310. A spring removal opening 141 is also formed on the adjacent lower side of the expansion surface 300. At the same time, as the expansion surface 400 is unfolded, the total length of the spring storage and packaging container unit increases, the spring 500 is released, and the spring 500 located at the top is pushed to the spring removal opening 141 under the action of the elastic force, and the topmost spring 500 is removed from the spring removal opening 141.
