Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

FIG. 1 is a schematic view of a storage case according to an embodiment of the present invention; fig. 2 is an exploded view of the storage case 1 shown in fig. 1; fig. 3 is a partial sectional view of region a in fig. 1.

For convenience of description, the longitudinal direction of the storage box 1 is referred to as the x direction, the width direction of the storage box 1 is referred to as the y direction, and the height direction of the storage box 1 is referred to as the z direction.

Specifically, referring to fig. 1 and 2, the storage box 1 may include: the box body 11, the box body 11 may include a bottom wall 11a, a side wall 11b, and a receiving cavity 112 surrounded by the bottom wall 11a and the side wall 11b and having an opening 111.

For example, the side wall 11b may be disposed around the edge of the bottom wall 11a to form a closed structure, and enclose the accommodating cavity 112 together with the bottom wall 11 a. The accommodating cavity 112 is suitable for accommodating the stored objects. The side of the sidewall 11b not connected to the bottom wall 11a defines an opening 111, and a user can place a storage object into the accommodating cavity 112 through the opening 111 or take out the storage object from the accommodating cavity 112 through the opening 111.

Further, the storage box 1 further includes: a cover 12, the cover 12 being adapted to open or close the opening 111, a side of the cover 12 facing the opening 111 including a mounting portion 121.

For example, the mounting portion 121 may be disposed along an edge of the cover 12 and form a closed structure. The mounting portion 121 extends from the cover 12 toward the accommodating chamber 112 and extends toward the accommodating chamber 112 substantially in the direction opposite to the z direction.

The mounting portion 121 and the cover 12 may be integrally formed. Alternatively, the mounting portion 121 may be fixed to the cover 12 by bonding, splicing, mortise and tenon joining, or the like.

Further, the storage box 1 may further include: and the sealing element 13 is sleeved on the mounting part 121.

For example, the sealing member 13 is sleeved outside the mounting portion 121, which is a side of the mounting portion 121 facing the edge of the cover 12.

Further, when the cover 12 closes the opening 111, the mounting portion 121 protrudes into the accommodating chamber 112, and the sealing member 13 includes a sealing portion 131 between the inner surface 113 of the sidewall 11b and the mounting portion 121.

With the solution of the present embodiment, an improved storage box 1 can be provided, which provides a sealing performance, while the sealing member 13 is also easy to detach and install and easy to clean. When the lid 12 closes the case 11, the seal 13 is substantially located in the case 11, and the overall appearance is high. Specifically, the sealing member 13 is sleeved and connected with the mounting portion 121, and is easy to assemble and clean. Further, when the cover 12 closes the opening 111, the mounting portion 121 extends into the accommodating cavity 112, and the sealing member 13, particularly the sealing portion 131, is located on the inner side of the box body 11 as a whole, and is not directly exposed outside the box body 11, which is beneficial to the overall appearance of the product. The inner side of the box 11 is a side close to the accommodating chamber 112.

In one embodiment, the seal 13 may be visible from outside the storage box 1 when the lid 12 closes the box body 11. Thus, the user can confirm that the storage box 1 is a storage box with a sealing function without opening the storage box 1.

To this end, at least one of the case 11 and the cover 12 may be transparent. To improve the visibility of the seal 13, the seal 13 may have a color that is clearly distinguished from the case 11 or the lid 12.

It should be noted that, although the quadrangular cover 12, the box body 11 and the sealing member 13 are exemplarily illustrated in fig. 1 to 3, in practical applications, the shape of the storage box 1 may be adjusted as needed, such as an oval shape, a polygonal shape, and the like.

In one implementation, the sealing portion 131 is in interference fit with the sidewall 11b when the cover 12 closes the opening 111, so as to achieve a good sealing effect.

In one implementation, the sealing member 13 may be made of an elastic material to be retained to the mounting portion 121 by elastic deformation to prevent the sealing member 13 from being undesirably removed from the mounting portion 121 during ordinary use.

For example, the sealing member 13 may be made of silicone rubber to fix the sealing member 13 to the cover 12 by utilizing the easy deformation characteristic of silicone rubber.

In one embodiment, referring to fig. 2 and 3, the sealing portion 131 may be sleeved on the end 121a of the mounting portion 121 to be effectively pressed against the inner surface 113 of the sidewall 11b after the mounting portion 121 is inserted into the receiving cavity 112, so as to ensure a good sealing effect. The end 121a of the mounting portion 121 refers to an end of the mounting portion 121 away from the cover 12.

In one embodiment, with continued reference to FIG. 3, the sealing member 13 may include a root portion 132 spaced from the inner surface 113 of the sidewall 11b to reduce friction between the lid 12 and the housing 11 when the opening is opened, which may reduce resistance to removal of the lid 12 from the housing 11, and may facilitate opening and closing of the storage box 1. Further, since the sealing portion 131 is interference-fitted with the side wall 11b when the lid 12 closes the opening, the sealing performance is not affected.

Specifically, the pitch means that the root portion 132 does not contact the inner surface of the side wall 11 b.

In one embodiment, a step 133 may be formed between the sealing portion 131 and the root portion 132 to form a gap and enable the sealing portion 131 to effectively abut against the inner surface 113 of the sidewall 11b when the cover 12 closes the opening 111, thereby ensuring a sealing effect.

Specifically, the step 133 may extend obliquely to the opposite direction of the z-direction and the x-direction, as shown in fig. 3.

Alternatively, the step 133 may be a platform extending in the x-direction.

In one implementation, the thickness of the sealing portion 131 may be greater than the thickness of the root portion 132, such that the root portion 132 is spaced from the inner surface 113 of the sidewall 11b while the sealing portion 131 is in interference fit with the sidewall 11 b. Wherein, the thickness of the sealing part 131 refers to the width of the sealing part 131 along the x direction; the thickness of the root 132 refers to the width of the root 132 in the x-direction.

Further, the difference in thickness between the sealing portion 131 and the root portion 132 may be gradually varied. That is, the thickness of the seal 13 is gradually increased from the root portion 132 to the seal portion 131, as shown in fig. 3, so that the root portion 132 is gently transited to the seal portion 131.

In one implementation, with continued reference to fig. 2 and 3, a side of the mounting portion 121 near the rim of the cover 12 is recessed away from the rim to form a recess 122, and the sealing portion 131 is located outside the recess 122. Thus, the design of the recessed portion 122 is beneficial to ensure a firm bond between the sealing member 13 and the mounting portion 121, and to prevent the sealing member 13 from falling off the cover 12 during use. Further, the sealing portion 131 is located outside the recess 122 to ensure a good sealing effect.

Specifically, the recess 122 may be formed only by one side of the mounting portion 121 near the rim of the cover 12. That is, for the portion of the mounting portion 121 connected to the cover 12, the side of the mounting portion 121 facing the center of the cover 12 extends in the z direction, and the side of the mounting portion 121 facing the edge of the cover 12 is recessed inward to form a recessed portion 122.

Alternatively, the recess 122 may be formed by integrally recessing the portion of the mounting portion 121 connected to the cover 12 toward the center of the cover 12.

Further, the root 132 may be interference fit over the recess 122 to ensure that the seal 13 is securely mounted on the cap 12.

In one implementation, there is a non-zero spacing between the portion of the seal 13 located within the recess 122 and the inner surface 113 of the sidewall 11 b. The portion of the seal 13 located in the recess 122 thus forms the root portion 132, which is suitable for firmly fixing the seal 13 to the lid 12 on the one hand, and for reducing the resistance when opening the lid 12 on the other hand.

In one implementation, the sealing member 13 is disposed around the mounting portion 121 and forms a closed structure, wherein an area of a region surrounded by a portion of the sealing member 13 close to the cover 12 is smaller than an area of a region surrounded by the sealing portion 131.

Particularly, the closed structure is beneficial to the all-round sealed box body 11, and the sealing effect is ensured. The portion of the seal 3 adjacent to the lid 12 forms the root portion 132, and the smaller area of the surrounding area means that the portion of the seal 13 is spaced from the inner surface of the side wall 11b, making it possible to reduce the resistance of the lid 12. The large area of the area enclosed by the sealing portion 131 means that this portion of the sealing member 13 can be tightly pressed against the side wall 11b to ensure a good sealing effect.

The area of the region enclosed by the part of the sealing member 13 close to the cover 12 may refer to the area of the part of the structure in the plane formed by the x direction and the y direction. Similarly, the area of the region surrounded by the sealing portion 131 may refer to the area of the sealing portion 131 in the plane formed by the x direction and the y direction.

In one implementation, the cover 12 may include an abutting portion 123 abutting against the upper end surface 114 of the side wall 11b when the cover 12 closes the opening 111. The upper end surface 114 of the side wall 11b refers to an end surface of the side wall 11b on the side not connected to the bottom wall 11 a.

Specifically, the abutting portion 123 may substantially cover the upper end surface 114 of the side wall 11b, so as to have an air-isolating effect to some extent.

For example, the abutting portion 123 may be formed by slightly bending the edge of the cover 12 in the direction opposite to the z direction,

further, a gap 124 is formed between the mounting portion 121 and the abutting portion 123, and the sealing member 13 is located in the gap 124.

Therefore, when the cover 12 closes the opening 111, the sealing member 13 is enclosed in the box body 11 by the abutting portion 123 and the side wall 11b, and the whole sealing member 13 is not exposed outside the box body 11, which is beneficial to the overall beauty of the product. Since the abutting portion 123 is adapted to abut against the upper end surface 114 of the side wall 11b, and the mounting portion 121 extends downward from the side of the cover 12 facing the opening 111, the gap 124 between the mounting portion 121 and the abutting portion 123 is similar to an inverted L shape, and the structure is simple, dirt is not easily accumulated, and cleaning is also easy.

In one embodiment, the sealing element 13 may include a flange 134 attached to the lower surface 12a of the cover 12 and extending toward the retaining portion 123 to facilitate assembly of the sealing element 13 in place.

Specifically, the lower surface 12a of the cover 12, i.e., the side of the cover 12 facing the opening 111, i.e., the side where the mounting portion 121 is provided.

For example, during assembly, the root portion 132 is fitted over the recess 122 and the flange 134 is secured against the lower surface 12a of the lid 12. At this time, the sealing portion 131 located outside the recess 122 can be interference-fitted with the inner surface of the side wall 11b when the cover 12 closes the opening 111 to perform a sealing function.

In one implementation, the thickness of the sealing portion 131 increases in a direction away from the cover 12 (i.e., opposite the illustrated z-direction). Thereby, on the one hand, a sealing effect with the case 12 is ensured, and on the other hand, the sealing portion 131 with the gradually increasing thickness can form a structure similar to a bell mouth, and can play a certain guiding role when the cover 12 is covered.

For example, in the present embodiment, the tip 121a of the mounting portion 121 may be extended along the z-direction, with an interference fit with the sidewall 11b being ensured by the sealing portion 131 having a gradually increasing thickness.

In one implementation, when the cover 12 does not close the opening 111, there may be a gap 135 between the sealing portion 131 and the end 121a of the mounting portion 121. The storage box 1 can be opened and closed more easily, and the sealing piece 13 can be avoided in the opening and closing operation.

For example, in this embodiment, the seal 13 and the mounting portion 121 are loosely fitted together, the root portion 132 is fitted into the recess 122 with interference, and the sealing portion 131 extending downward is loosely fitted outside the end 121a of the mounting portion 121. When the cover 12 closes the opening 111, the sealing member 13 extends into the box body 11 along with the mounting portion 121, and during the extending process, the sealing portion 131 slightly moves towards the mounting portion 121 under the extrusion of the side wall 11b of the box body 11 until the abutting portion 123 abuts against the upper end surface 114 of the side wall 11 b. At this time, the sealing portion 131 is pressed between the tip 121a of the mounting portion 121 and the inner surface 113 of the sidewall 11b, and is pressed and deformed to perform a sealing function.

When the cover 12 closes the opening 111, the interval 135 between the sealing portion 131 and the tip 121a of the mounting portion 121 may disappear.

In one embodiment, the end 121a of the mounting portion 121 is angled toward the edge of the cover 12 in a direction away from the cover 12 (i.e., opposite the z direction shown) to form a flare to guide the cover 12 and facilitate assembly of the seal 13 to the mounting portion 121.

For example, the mounting portion 121 extends downward from the lower surface 12a of the cover 12 in the direction opposite to the z-direction for a certain distance, and then is bent in the direction of the edge of the cover 12 while continuing to extend downward, so as to form a bell-mouth structure at the end 121a of the mounting portion 121.

In one implementation, the thickness of the end 121a of the mounting portion 121 is tapered in a direction away from the cover (i.e., opposite the illustrated z-direction) to increase flexibility to facilitate mounting of the seal 13 and to facilitate demolding during the manufacturing stage. Further, it is also advantageous to avoid the seal member 13 from slipping down.

In one embodiment, a slope of a side 126 of the end 121a of the mounting portion 121 facing the sealing portion 13 to the edge of the cover 12 may be smaller than a slope of a side 127 of the end 121a of the mounting portion 121 facing away from the sealing portion 13 to the edge of the cover 12. Therefore, when the cover 12 closes the opening 111, the force applied to the mounting portion 121 is small, which is beneficial to prolonging the service life. In addition, the design having different slopes on both sides can also achieve the effect of gradually reducing the thickness of the end 121a of the mounting portion 121.

In one implementation, for the side 126 of the end 121a of the mounting portion 121 facing the sealing portion 13, the slope of the portion of the end 121a of the mounting portion 121 contacting the step 133 of the sealing member 13 may be substantially parallel to the extending direction of the step 133, so that the structure of the mounting portion 121 substantially conforms to the structure of the sealing member 13.

Further, with respect to the side 126 of the tip end 121a of the mounting portion 121 facing the sealing portion 13, a portion of the tip end 121a of the mounting portion 121 contacting the sealing portion 131 may be extended in the opposite direction to the z direction. Thereby, when the cover 12 closes the opening 111, the sealing portion 131 is largely pressed by the distal end 121a of the mounting portion 121 and the inner surface 113 of the sidewall 11b to obtain a better bee effect.

Further, in the opposite direction to the z direction, the side 127 of the end 121a of the mounting portion 121 facing away from the seal 13 may always slope towards the rim of the cover 12, with the slope remaining unchanged.

In one implementation, referring to fig. 4, the storage box 1 may be applied to a refrigerating and freezing storage scene such as a refrigerator 2. The storage box 1 provides sealing performance, and meanwhile, the sealing piece 13 is easy to detach and install and clean. When the lid 12 closes the case 11, the seal 13 is substantially located in the case 11, and the overall appearance is high.

Specifically, the refrigerator 2 may include a storage chamber 21, and a user may take the storage box 1 out of or into the storage chamber 21 as needed to extend the shelf life of stored goods using the sealing property of the storage box 1 and to facilitate prevention of taint.

Further, the refrigerator 2 may be provided with one or more brackets 22, and the storage box 1 may be carried in the storage chamber 1 through the brackets 22 to fully utilize the storage space in the storage chamber 21.

Further, the number of the storage boxes 1 placed in the refrigerator 2 may be plural. And the sizes and the volumes of the storage boxes 1 can be different, so that the storage box is suitable for the diversified storage requirements of users.

Further, the refrigerator 2 may further include a door (not shown) for exposing or closing the storage chamber 21.
