Description

Technical Field

[0001] The present invention relates to the field of spring packaging, and more particularly to a spring storage and retrieval packaging container unit, container and method. Background Art

[0002] The spring packaging boxes on the market are mainly compartmentalized boxes. For example, CN207684180U divides the space into four quadrants by supporting frames and partitions, and each space is filled with a spring. The partitions and baffles increase the space required for spring packaging. CN201999334U puts multiple springs end to end on a long paper strip, and then packs them. The direct contact between the springs reduces the space wasted by the packaging materials. However, this solution only folds the two ends of the long paper strip to prevent the spring from detaching from the long paper strip. The spring is in a natural state and is long, which still cannot effectively save packaging space.

[0003] Combining the above two solutions, we can put multiple springs end to end into a long strip packaging container and compress them. This method can effectively save packaging space. However, traditional packaging tubes are mostly structures with one end closed and the other end open or both ends open. The open end surface needs to be closed with a lid. If the spring is placed in a packaging container and compressed, the compressed spring will tend to restore its original length and pop out from the open end of the packaging tube. It is necessary to apply additional pressure to the spring to cover the packaging tube. The same is true when opening the lid to take out the object. The compressed spring will pop out directly from the open end and cannot be taken out in a controllable manner. Therefore, traditional long strip packaging containers are not suitable for compressed storage and retrieval of springs. Summary of the invention

[0004] The main technical problem 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.

[0005] In order to solve the above-mentioned 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 in the shape of an elongated strip and 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. 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 surface of the box body.

[0006] The above technical solution sets the spring removal opening of the spring storage and access packaging container unit on the top side of the box body. The direction of the elastic force of the spring 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 an open state, the spring is not easily ejected by the elastic force, and the spring can be removed in a controllable manner.

[0007] Furthermore, a one-way paddle extending toward the inside of the box body is provided on the bottom surface of the box body, and the one-way paddle can only be deformed in the forward direction and cannot be deformed in the reverse direction. In the above scheme, when the spring is pressed into the box body from the bottom surface of the box body, the one-way paddle is deformed in the forward direction, and 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.

[0008] 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.

[0009] Furthermore, the one-way paddle is integrally formed with the box body. In the above solution, the spring storage and access packaging container unit has the advantage of a simple structure.

[0010] Furthermore, one end of the one-way paddle close to the bottom surface of the box body extends to form a connecting wall, and the connecting wall is connected to the outer wall of the bottom side of the box body. The connection method of the connecting wall and the outer wall of the bottom side of the box body mentioned in the above technical solution includes but is not limited to snap connection, plug connection, thread connection, sleeve connection and bonding.

[0011] Furthermore, the connecting walls of the multiple one-way paddles are connected to form an annular structure, which is sleeved on the outer wall of the side surface of the bottom end of the box body and has an interference fit with the side surface of the bottom end of the box body. In the above technical solution, since the annular structure abuts against the outer wall of the side surface of the bottom end of the box body, it can further prevent the one-way paddle from reverse deformation, and has a higher structural reliability. In addition, the positions of the multiple one-way paddles and the annular structure are relatively fixed, and the annular structure has an interference fit with the side surface of the bottom end of the box body, which has the advantages of easy installation, simple structure and stability.

[0012] Furthermore, the box body is provided with a take-out cover, and when the spring take-out opening is closed, the take-out cover covers the spring take-out opening. In the above technical solution, the take-out cover can prevent the spring from leaving the box body from the spring take-out opening when it is not needed to be taken out. The take-out cover can be integrally formed with the box body, or can be a cover plate provided on the box body through a slide rail, or a cylinder sleeved on the outer wall of the top side of the box body, etc.

[0013] In a second aspect, the present application also provides a spring storage and retrieval packaging container, comprising at least two of the above-mentioned spring storage and retrieval packaging container units. The above-mentioned spring storage and retrieval packaging container has the advantage of being able to controllably place and take out springs. In addition, when there are a large number of springs, placing the springs in a plurality of separately movable spring storage and retrieval packaging container units can effectively reduce the weight of each spring storage and retrieval packaging container unit, making storage and transportation more convenient. Furthermore, a plurality of spring storage and retrieval packaging container units can be assembled or disassembled.

[0014] On the third aspect, the present application provides another spring storage and retrieval packaging container unit, the box body of the spring storage and retrieval packaging container unit is a prism, 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, 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.

[0015] 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.

[0016] Further, the second top surface can be separated into two connecting surfaces.

[0017] Furthermore, a one-way paddle extending toward the inside of the box body is provided at the bottom of the box body, and the one-way paddle can only be deformed in the forward direction and cannot be deformed in the reverse direction. In the above scheme, when the spring is pressed into the box body from the bottom of the box body, the one-way paddle is deformed in the forward direction, and 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.

[0018] 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.

[0019] Furthermore, the one-way paddle is integrally formed with the box body.

[0020] Furthermore, one end of the one-way paddle close to the bottom of the box body extends to form a connecting wall, and the connecting wall is connected to the outer wall of the bottom side of the outer side of the box body. The connection method of the connecting wall and the outer wall of the bottom side of the box body mentioned in the above technical solution includes but is not limited to snap connection, plug connection, thread connection, sleeve connection and bonding.

[0021] Furthermore, the connecting walls of the multiple one-way paddles are connected to form an annular structure, which is sleeved on the outer wall of the side surface of the bottom end of the box body and has an interference fit with the side surface of the bottom end of the box body. In the above technical solution, since the annular structure abuts against the outer wall of the side surface of the bottom end of the box body, it can further prevent the one-way paddle from reverse deformation, and has a higher structural reliability. In addition, the positions of the multiple one-way paddles and the annular structure are relatively fixed, and the annular structure has an interference fit with the side surface of the bottom end of the box body, which has the advantages of easy installation, simple structure and stability.

[0022] In a fourth aspect, the present application provides a spring storage and retrieval packaging container, comprising at least two of the above-mentioned spring storage and retrieval packaging container units. The above-mentioned spring storage and retrieval packaging container has the advantage of being able to controllably place and take out springs. In addition, when there are a large number of springs, placing the springs in a plurality of separately movable spring storage and retrieval packaging container units can effectively reduce the weight of each spring storage and retrieval packaging container unit, making storage and transportation more convenient. Furthermore, a plurality of spring storage and retrieval packaging container units can be assembled or disassembled.

[0023] In a fifth aspect, the present application provides a spring storage and retrieval packaging method, comprising a spring storage and retrieval packaging container unit, wherein the box body of the spring storage and retrieval packaging container unit is in an elongated strip 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 inside of the box body, and a spring removal opening is provided on the side surface of the top end of the box body;

[0024] When the spring needs to be put in, insert the spring from the bottom of the box body, and the springs are loaded in a single row in sequence;

[0025] When the spring needs to be taken out, the spring taking-out opening is opened, and the spring located 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.

[0027] When the spring needs to be put in, 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 loaded in a single row in sequence;

[0028] When the spring needs to be taken out, the two extended surfaces are unfolded to form a second top surface, so that 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.

[0029] Compared with the prior art, this application has the following beneficial effects:

[0030] 1. By opening 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, so that the spring can be removed in a controlled manner.

DETAILED DESCRIPTION

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0051] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0052] Slightly larger than in the present application means that the cross section of the box body 100 can cover the maximum cross section of the spring 500 and the cross section area of ​​the box body 100 is not larger than 30% of the maximum cross section area of ​​the spring 500. If the cross section area of ​​the box body 100 is larger than 30% of the maximum cross section area of ​​the spring 500, the spring 500 may bend or fall away from the long axis direction of the box body 100 after entering the box body 100, causing the two springs 500 to be blocked laterally in the box body 100 and unable to move from the bottom surface of the box body to the top surface of the box body under the action of elastic force. Preferably, the cross section of the box body is larger than 10% of the cross section area of ​​the spring.

[0053] In the present application, “upper” as a directional word refers to the direction from the bottom surface 110 of the box body to the top surface 130 of the box body along the long axis of the box body 100 , and “lower” as a directional word refers to the direction from the top surface 130 of the box body to the bottom surface 110 of the box body along the long axis of the box body 100 .

[0054] Embodiment 1

[0055] The box body 100 of the spring storage and access packaging container unit provided in the first embodiment is an integrally formed plastic part. Figure 1 This is a three-dimensional structural diagram of the spring storage and retrieval packaging container unit provided in Example 1. As shown in the figure, the box body 100 of the spring storage and retrieval packaging container unit is a quadrangular prism, the top surface of the box body (not shown in the figure) 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.

[0056] Figure 2 A longitudinal cross-sectional view of the spring access packaging container unit provided in the first embodiment, Figure 3 This is a bottom view of the spring storage and access packaging container unit provided in the first embodiment. It can be seen from the figure that 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 paddle 200 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). Figure 2 As can be seen in the figure, the one-way paddle 200 extends toward the inside of the box body 100 and forms an acute angle with the box body 100, and can be deformed in the direction of the top surface 130 of the box body.

[0057] Embodiment 2

[0058] The following is a spring storage and access packaging container unit of the first embodiment as a container combination. Figure 4-Figure 8 The spring storage and retrieval packaging method and the spring storage and retrieval process provided in the second embodiment are described.

[0059] Figure 4-Figure 6 The schematic diagram of the process of placing the spring 500 into the container is shown below. When the spring 500 needs to be placed into the container:

[0060] 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 a forward deformation with a reduced acute angle. Then, the spring 500 leaves the one-way paddle 200 and slides toward the top surface 130 of the box body.

[0061] A plurality of springs 500 are connected end to end and loaded 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 one-way paddle 200 cannot deform in the reverse direction, the spring 500 cannot leave the box body 100 from the bottom surface 110 of the box body.

[0062] Figure 7-Figure 8 The schematic diagram of the process of taking the spring 500 out of the container is shown in FIG. 1 . When the spring 500 needs to be taken out:

[0063] Open the removal cover 142 and remove the spring 500 at the top from the spring removal opening 141. Then, as the number of springs 500 decreases, the compression of the spring 500 gradually decreases, and the length of the spring 500 increases. The top spring 500 is pushed to the spring removal opening 141 under the action of elastic force. Repeat the above operation until all required springs 500 are removed.

[0064] Embodiment 3

The bottom surface 110 of the box body is provided with four one-way paddles 200 (not shown in the figure, see Fig.10 ), one end of the one-way paddle 200 close to the bottom surface 110 of the box body extends to form a connecting wall 210, and the four one-way paddles 200 connecting walls 210 are connected to form an annular structure that is sleeved on the outer wall of the bottom side surface 120 of the box body.

[0066] Fig.10 A longitudinal cross-sectional view of a spring access packaging container unit provided in Embodiment 3, Fig.11 This is a top 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 equally spaced 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.

The spring storage and access packaging container unit can be obtained by bonding the two adhesive surfaces to each other. Among them, the box body 100 of the spring storage and access packaging container unit of the fifth embodiment is a quadrangular prism, and 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 opposite 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 on 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 Fig.18 Two opposite first top surfaces 400 are formed extending above the top side surface 140 of the box body and adjacent to the extension surface 300 , and the two first top surfaces 400 can be connected by an insert.

[0072] The bottom side 120 of the box body is provided with four one-way paddles 200 (at Fig.15 In the figure, the one-way paddle is in the unfolded state and has not yet extended into the box body), and one end of the one-way paddle 200 close to the bottom surface 110 of the box body extends to form a connecting wall 210 (not shown in the figure, see Fig.16), a limit buckle 211 is provided on the connecting wall 210, and a slot 121 corresponding to the limit buckle 211 is provided on the bottom side 120 of the box body. The one-way paddle 200 is connected to the bottom side 120 of the box body through the cooperation between the limit buckle 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.

[0075] Embodiment 6

[0076] The following is a spring storage and access packaging container unit of Example 6 as a container combination. Figure 19-Figure 23 The spring storage and retrieval packaging method and the spring storage and retrieval process provided in the sixth embodiment are described.

[0077] Figure 19-20 The schematic diagram of the process of placing the spring 500 into the container is shown below. When the spring 500 needs to be placed into the container:

[0078] 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 .

[0079] 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 a forward deformation with a reduced acute angle. Then, the spring 500 leaves the one-way paddle 200 and slides toward the top surface 130 of the box body.

[0080] A plurality of springs 500 are connected end to end and loaded 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 one-way paddle 200 cannot deform in the reverse direction, the spring 500 cannot leave the box body 100 from the bottom surface 110 of the box body.

[0081] Figure 21-23 The schematic diagram of the process of putting the spring 500 into the container is shown below. When the spring 500 needs to be taken out:

[0082] The two first top surfaces 400 are separated, and after confirming that the connecting surfaces 311 of the two extended surfaces 300 are in a connected state, the extended surfaces 300 are unfolded, and the connecting surfaces 311 form the second top surface 310 and form a spring removal opening 141 on the adjacent surface of the extended surface 300. At the same time, as the extended surface 400 is unfolded, the total length of the spring storage and access packaging container unit increases, the compression amount of the spring 500 decreases, and the spring 500 at the top is pushed to the spring removal opening 141 under the action of the elastic force, and the spring 500 at the top is taken out from the spring removal opening 141.
