Description

TECHNICAL FIELD

The present disclosure belongs to the field of storage boxes, and specifically relates to a storage box for personal private items such as breast pasties, underwear, or other personal private items.

BACKGROUND

Existing storage boxes, particularly those designed for storing personal items such as breast pasties, underwear, or other private articles, generally suffer from the following issues.

Firstly, these storage boxes are only used for storing items, and their function is single. Secondly, after use, breast pasties may have sweat, dust, hairs, bacteria, and other contaminants attached to them. Cleaning is required after use, and if not cleaned promptly, the stickiness of the breast pasties will be significantly reduced. Generally, breast pasties need to be dried before they can be stored in the storage box, but existing storage boxes do not have a drying function, requiring users to find a hanger or a suitable place to dry the breast pasties. Thirdly, as breast pasties are personal items for intimate areas of women, it is unhygienic to dry them without a dedicated hanger. Lastly, if the breast pasties are placed in an inappropriate position or angle after cleaning, water droplets may easily remain on the surface, making it difficult to dry.

The storage box of the present disclosure has the following advantages or beneficial effects.

Firstly, in addition to its normal storage function, this storage box also features multiple functions such as drying and supporting. Breast pasties that have been used or cleaned can be hung vertically on the drying support member, facilitating quick drying.

Secondly, after cleaning, there is no need to look for another hanger to dry the breast pasties. By opening the drying support member of the storage box, it can be used to dry the breast pasties, making it convenient to use and not occupying space.

Thirdly, using the drying support device built into the storage box for drying can serve as a personal exclusive hanger, ensuring cleanliness and hygiene. At the same time, when the breast pasties are supported on the drying support member, any residual water droplets on their surface can flow into the storage box and be easily discarded, preventing the drying area from getting wet or dirty.

Fourthly, the drying support member is cleverly cooperated with the shaft sleeve mechanism, as well as the upper cover and the lower cover, to stand upright and be supported on the storage box. As the drying support member must rotate synchronously with either the upper cover or the lower cover when returning to its original position, the upper cover and the lower cover, due to their own weight, create a certain moment arm and torque with the key shaft. Furthermore, the rotation limiting portion inside the shaft sleeve mechanism and the keys on the corresponding adaptation section of the drying support member provide resistance, preventing the key shaft from rotating easily, and consequently, the drying support member from rotating easily. When the drying support member is in its working state and standing upright on the storage box, it will not easily fall over. This rotating support structure of the drying support member is compact, ingenious, stable, and reliable.

Fifthly, if the angle between the upper cover and the lower cover does not exceed 90 degrees when opening the storage box, the drying support member remains in its closed position, which does not interfere with the removal or placement of breast pasties or other items.

Lastly, the drying support member of the storage box shares one key shaft with the upper cover and the lower cover, and the drying support member is integrated with the upper cover and the lower cover of the storage box, making the entire structure of the storage box compact, ingenious, stable, and reliable.

Corresponding keys are arranged at the corresponding positions in the circumferential direction of the shaft body 410 for mating with the upper cover shaft sleeve 12, the lower cover shaft sleeve 21a, and the drying support member shaft sleeve 32.

To facilitate the explanation and understanding of the transmission and mating relationship between the key shaft 41 and the upper cover shaft sleeve 12, the lower cover shaft sleeve 21a, and the drying support member shaft sleeve 32, the key shaft 41 can be divided into a plurality of adaptation sections. As shown in FIG. 18, in this embodiment, the key shaft 41 comprises a lower cover shaft sleeve adaptation section 411a, an upper cover shaft sleeve adaptation section 412, and a drying support member shaft sleeve adaptation section 413. The lower cover shaft sleeve adaptation section 411a is matched with the lower cover shaft sleeve 21a, the upper cover shaft sleeve adaptation section 412 is matched with the upper cover shaft sleeve 12, and the drying support member shaft sleeve adaptation section 413 is matched with the drying support member shaft sleeve 32. The upper cover 1 is rotatably connected to the upper cover shaft sleeve adaptation section 412 of the key shaft 41 via the upper cover shaft sleeve 12, and the lower cover 2 is rotatably connected to the lower cover shaft sleeve adaptation section 411a of the key shaft 41 via the lower cover shaft sleeve 21a, thus allowing the upper cover 1 and the lower cover 2 to be rotatably connected through the key shaft 41.

The lower cover shaft sleeve adaptation section 411a of the key shaft 41 comprises an outer lower cover shaft sleeve adaptation section 411 matched with the outer lower cover shaft sleeve 22, the outer lower cover shaft sleeve adaptation section 411 is provided with an outer lower cover key 411b, a number of the outer lower cover key 411b is two, the two outer lower cover keys 411b are respectively a first outer lower cover key 4111 and a second outer lower cover key 4112, and the two outer lower cover keys 411b are used for being matched with the outer lower cover shaft sleeve 22, the first outer lower cover key 4111 is located at a position of 180 degrees in a circumferential direction of the key shaft 41, and the second outer lower cover key 4112 is located at a position of 270 degrees in the circumferential direction of the key shaft 41.

The upper cover shaft sleeve adaptation section 412 is provided with an upper cover key 412a, a number of the upper cover key 412a is two, the two upper cover keys 412a are respectively a first upper cover key 4121 and a second upper cover key 4122, and the two upper cover keys 412a are used for being matched with the upper cover shaft sleeve 12, the first upper cover key 4121 is located at a position of 90 degrees in the circumferential direction of the key shaft 41, and the second upper cover key 4122 is located at a position of 180 degrees in the circumferential direction of the key shaft 41.

At least one of the drying support member key 4131 is provided on the drying support member shaft sleeve adaptation section 413, located at the circumferential positions of 90 degrees, 180 degrees, 270 degrees, or 0 degrees of the key shaft 41, and the drying support member key 4131 is used for being matched with the drying support member key groove 322 of the drying support member shaft sleeve 32.

In the embodiment, since four drying support member key grooves 322 are formed in the drying support member shaft sleeve 32, four drying support member keys 4131 are arranged on the drying support member shaft sleeve adaptation section 413 and matched with the four drying support member key grooves 322, the four drying support member keys 4131 are located at the positions of 0 degrees, 90 degrees, 180 degrees and 270 degrees in the circumferential direction of the key shaft 41 respectively, so that the key shaft 41 can drive the drying support member 3 to rotate synchronously, and the assembling structures of the four drying support member keys 4131 and the four drying support member key grooves 322 are more stable, reliable and durable. It can be understood that the drying support member key groove 322 cannot be provided at a position of 0 degrees in the circumferential direction of the drying support member shaft hole 321, and the drying support member key 4131 cannot be provided at a position of 0 degrees in the circumferential direction of the drying support member shaft sleeve adaptation section 413 of the key shaft 41. The drying support member 3 is sleeved on the drying support member shaft sleeve adaptation section 413 of the key shaft 41 via the drying support member shaft sleeve 32, and the drying support member key 4131 penetrates into the drying support member key groove 322 to form a transmission matching relationship with the drying support member key groove 322, so that the drying support member 3 and the key shaft 41 rotate synchronously.

In the embodiment, the lower cover shaft sleeve 21a further comprises an inner lower cover shaft sleeve 23, and correspondingly, the key shaft 41 further comprises an inner lower cover shaft sleeve adaptation section 414 matched with the inner lower cover shaft sleeve 23, so that the structure between the whole shaft sleeve mechanism 4 and the drying support member 3 is more compact, stable and durable.

The inner lower cover shaft sleeve 23 is completely the same as the outer lower cover shaft sleeve 22, and only the inner lower cover shaft sleeve 23 is located at the position closer to the center line of the inner side of the lower cover 2. In the embodiment, the upper cover shaft sleeve 12 is located between the inner lower cover shaft sleeve 23 and the outer lower cover shaft sleeve 22, so that the structure is more compact and stable.

The storage box further comprises a handle 6. The key shaft 41 further comprises a handle adaptation section 415 for mounting the handle 6. No key is provided on the handle adaptation section 415, facilitating free rotation of the handle 6 around the key shaft 41 without being restrained by a key.

The lock box mechanism 5 comprises a lock cover buckling portion 51, a lock cover 52 and a lock cover rotating shaft portion 53, the lock cover buckling portion 51 is provided on the upper cover 1, the lock cover rotating shaft portion 53 is provided on the lower cover 2, the lock cover rotating shaft portion 53 is provided with a lock cover rotating shaft 531, and the lock cover 52 is rotatably connected to the lower cover 2 via the lock cover rotating shaft 531 on the lock cover rotating shaft portion 53.

The handle 6 is provided with a handle shaft sleeve 61 used for sleeving the key shaft 41, a handle shaft hole 611 matched with the handle adaptation section 415 is formed in the handle shaft sleeve 61, and an inner side wall of the handle shaft hole 611 is provided with a plurality of handle key grooves 612. Each handle key groove 612 is used for allowing a key on the key shaft 41 to pass through when the key shaft 41 is installed or removed. In the embodiment, four handle key grooves 612 are formed in the inner side wall of the handle shaft hole 611, and the four handle key grooves 612 are arranged in the positions of 0 degrees, 90 degrees, 180 degrees and 270 degrees in the circumferential direction of the handle shaft hole 611 in a cross shape, so that when the handle 6 is sleeved on the key shaft 41, the handle 6 and the key shaft 41 do not interfere. The end, away from the handle shaft sleeve 61, of the handle is a free end 62. When the storage box is completely opened and the drying support member 3 is in a vertical state, the handle 6 is located in a gap between the upper cover 1 and the lower cover 2, and a set distance H (as shown in FIGS. 12 and 13) is arranged between an end surface of the free end 62 of the handle 6 and either an end surface of the upper cover or an end surface of the lower cover. This ensures that the handle does not interfere with the operation and use of the storage box.

In the embodiment, to facilitate manufacturing and ensure the entire storage box is compact, stable, reliable, and durable, the keys on the key shaft are integrally formed with the key shaft; the upper cover shaft sleeve is integrally formed with the upper cover body, the lower cover shaft sleeve is integrally formed with the lower cover body, and the drying support member body is integrally formed with the drying support member shaft sleeve.

In use, with the closed position of the storage box designated as the initial position and the lower cover 2 serving as the stationary reference, if the upper cover 1 is used to open the storage box, the angle between the upper cover 1 and the lower cover 2 is 0 degrees, and the angle between the drying support member 3 and the lower cover 2 is also 0 degrees, meaning the initial position of the drying support member 3 is horizontal.

When the upper cover 1 is opened, due to the gravity of the lower cover 2 or the presence of items such as breast pads inside, the lower cover 2 remains stationary, allowing the upper cover 1 to rotate around the key shaft 41 in the opening direction. Before the upper cover 1 reaches the critical position, the upper cover 1 does not drive the key shaft 41 to rotate due to the presence of the upper key shaft avoiding hole 123 in the upper cover shaft sleeve 12.

When the upper cover 1 reaches the critical position (as shown in FIG. 14), the angle between the upper cover 1 and the lower cover 2 is 90 degrees. If the upper cover 1 continues to rotate, it will come into contact with the first upper cover key 4121 through the upper first rotation limiting portion 124, driving the key shaft 41 to rotate and, in turn, the drying support member 3 to rotate synchronously until the upper cover 1 reaches the final position. At this point, the second outer lower cover key 4112 on the outer lower cover shaft sleeve adaptation section 411 comes into contact with the lower first rotation limiting portion 224 inside the outer lower cover shaft sleeve, stopping the rotation of the key shaft 41. The angle between the upper cover 1 and the lower cover 2 is 180 degrees, the storage box reaches its maximum opening angle, and is fully open or in the working state. Simultaneously, the drying support member 3 also rotates to its final position, with an angle of 90 degrees between the drying support member 3 and the lower cover 2 (as shown in FIG. 12 or 13). The drying support member 3 reaches its maximum opening angle, is fully open or in the working state, and is in the supporting position, i.e., it is vertical.

Due to the gravity of the upper cover 1 and the lower cover 2, there is a certain force arm and torque relative to the key shaft, and since the key shaft 41 is limited by the upper first rotation limiting portion 124 and the lower first rotation limiting portion 224, it cannot rotate freely. This also prevents the drying support member 3, which rotates synchronously with the key shaft 41, from rotating freely, keeping it stationary or in the working state in the supporting position. In other words, the drying support member 3 is vertically supported on the storage box using the shaft sleeve mechanism 4.

To return the upper cover 1 or the drying support member 3 from the final position to the initial position, i.e., to change the angle between the upper cover 1 and the lower cover 2 from 180 degrees to 0 degrees, and the angle between the drying support member 3 and the lower cover 2 from 90 degrees to 0 degrees, the upper cover 1 can be rotated around the key shaft 41 in the closing direction.

When the upper cover 1 rotates from the final position in the closing direction, it will drive the drying support member 3 to rotate. When the upper cover 1 returns to the critical position, the angle between the upper cover 1 and the lower cover 2 is 90 degrees, and the drying support member 3 rotates back to its initial or closed position, i.e., the angle between the drying support member 3 and the lower cover 2 is 0 degrees. After this, the upper cover 1 continues to rotate in the closing direction, and the drying support member 3, having already returned to its original position, remains in the closed position. When the upper cover 1 continues to rotate until the angle between the upper cover 1 and the lower cover 2 returns to 0 degrees, it returns to the initial or closed position.

Similarly, if the lower cover 2 is used to open the storage box, with the upper cover 1 serving as the stationary reference, the angle between the upper cover 1 and the lower cover 2 is 0 degrees, and the angle between the drying support member 3 and the lower cover 2 is also 0 degrees, indicating that the initial position of the drying support member 3 is horizontal.

When the lower cover 2 is opened, due to the gravity of the upper cover 1 or the presence of items such as breast pads inside, the lower cover 2 remains stationary, allowing the lower cover 2 to rotate around the key shaft 41 in the opening direction. Before the lower cover 2 reaches the critical position, the lower cover 2 does not drive the key shaft 41 to rotate due to the presence of the lower key shaft avoiding hole 223 in the lower cover shaft sleeve.

When the lower cover 2 reaches the critical position, the angle between the lower cover and the upper cover is 90 degrees. If the lower cover 2 continues to rotate, it will come into contact with the second outer lower cover key 4112 through the lower first rotation limiting portion 224, driving the key shaft 41 to rotate and, in turn, the drying support member 3 to rotate synchronously until the lower cover 2 reaches the final position. At this point, the first upper cover key 4121 on the upper cover shaft sleeve adaptation section 412 comes into contact with the upper first rotation limiting portion 124 inside the upper cover shaft sleeve 12, stopping the rotation of the key shaft 41. The angle between the lower cover 2 and the upper cover 1 is 180 degrees, the storage box reaches its maximum opening angle, and is fully open or in the working state. Simultaneously, the drying support member 3 also rotates to its final position, with an angle of 90 degrees between the drying support member 3 and the lower cover 2 (as shown in FIG. 12 or 13). The drying support member 3 reaches its maximum opening angle, is fully open or in the working state, and is in the supporting position, i.e., it is vertical.

Due to the gravity of the upper cover 1 and the lower cover 2, there is a certain force arm and torque relative to the key shaft, and since the key shaft 41 is limited by the lower first rotation limiting portion 224 and the upper first rotation limiting portion 124, it cannot rotate freely. This also prevents the drying support member 3, which rotates synchronously with the key shaft 41, from rotating freely, keeping it stationary or in the working state in the supporting position. In other words, the drying support member 3 is vertically supported on the storage box using the shaft sleeve mechanism 4.

To return the lower cover 2 or the drying support member 3 from the final position to the initial position, i.e., to change the angle between the lower cover 2 and the upper cover 1 from 180 degrees to 0 degrees, and the angle between the drying support member 3 and the upper cover 1 from 90 degrees to 0 degrees, the lower cover 2 can be rotated around the key shaft 41 in the closing direction.

When the lower cover 2 rotates from the final position, it will drive the drying support member 3 to rotate. When the lower cover 2 returns to the critical position, the angle between the lower cover 2 and the upper cover 1 is 90 degrees, and the drying support member 3 rotates back to its initial or closed position, i.e., the angle between the drying support member 3 and the upper cover 1 is 0 degrees. After this, the lower cover 2 continues to rotate in the closing direction, and the drying support member 3, having already returned to its original position, remains in the closed position. When the lower cover 2 continues to rotate until the angle between the lower cover 2 and the upper cover 1 returns to 0 degrees, it returns to the initial or closed position.

It should be noted that if the angle between the upper cover 1 and the lower cover 2 does not exceed 90 degrees when opening the storage box, the drying support member 3 remains in its closed position, which does not interfere with the removal or placement of breast pasties or other items in the storage box.
