DETAILED DESCRIPTION

[0028] Figs. lAto II shows the different views of the container 10 of an embodiment of this disclosure. The container 10 includes a compressible portion 110 and a container base 120. The compressible portion 110 is connected to the container base 120. The height of the compressible portion 110 is adjustable according to the need of a user. The container base 120 may be made by a different material that is not compressible or not substantially compressible. The compressible portion 110 includes a bellow body 111, and the bellow body 111 includes at least two convolutions 112, 113. Each convolution has a first living hinge 114 (such as a crest of the convolution) and a sidewall 115. A second living hinge 116 (such as a root of two convolutions) is positioned between the two convolutions 112, 113. The second living hinge 116 is defined at the intersection of the convolutions 112, 113. The container 10 may have multiple convolutions, such as seven, or less or more, convolutions. Exemplarily, the top and the bottom of the compressible portion 110 each has a half of a convolution, and there are six convolutions between the top and bottom half convolutions. Further, the compressible portion 110 and the container base 120 can be made of silicone. The container base 120 can also be made of polypropylene or other material that has a rigidity higher than silicone.

[0029] The bellow body 111 further includes at least one moveable bump structure 210. The bump structure 210 is positioned between the two convolutions 112, 113 to space two first living hinges 114 apart. In this embodiment, the container 10 includes seven moveable bump structures 210 as an example. The bump structure 210 is movable between an outer position (as shown in Fig. 1) and an inner position (when a user has pushed the bump structure inwards, as shown in Fig. 1G) relative to a container interior 11. The bellow body 111 may include multiple duplicated layers. For example, the bellow body 111 may have multiple bump structures 210, which are positioned between two convolutions of the bellow body 111. As shown in Fig. 1 A as an example, there are seven bump structures in the compressible portion 110. It should be noted that the bump structure 210 is not necessarily a rounded structure. It can be a raised structure with any shape, such as, for example, a rectangular bump, a triangle bump, or a tent-shaped bump. Figs. 4A and 4B are illustrative cross- sectional views of the bump structure 210.

[0030] Additionally, the bump structures 210 are provided at two opposite sides of the compressible portion 110. In other implementations, the bump structures 210 can be provided on one side, two adjacent sides, three sides, or even all sides of the compressible portion 110. The length or size of the bump structures 210 at the different sides of the compressible portion 110 can be different. For example, the bump structures 210 on a shorter side of the compressible portion 110 may be shorter than bump structures 210 on a longer side of the compressible portion 110, or vice versa. Further, the bump structures 210 can be provided between every convolution (as shown in the Fig. 1A) or every two, three, or more convolutions. The bump structures 210 can distribute unevenly within one side of the compressible portion 110, and the bump structures 210 can have different distributions among different sides of the compressible portion 110.

[0031] Specifically, when the bump structure 210 is the an outer position as shown in Fig. 1, the bump structure 210 provides support to the adjacent convolutions and helps the container 10 to maintain the height of the compressible portion 110. When a user wants to compress the compressible portion 110 to reduce the overall height of the container 10, the user can push a certain amount of bump structures 210 inwards toward the container interior 11. Once a bump structure 210 is pressed inwards, the adjacent convolutions can be folded or compressed more easily. For example, a user can push all the seven bump structures inwards and to fully compress the compressible portion 110. Likewise, a user can choose to push only two, three, or five bump structures 210 inwards to reduce the height of the compressible portion 110 by a smaller amount. Figs. IF and 1G show the front views of the container 10. In Fig. 1G some bump structures 210 are indented and some are not. It should be noted that, in this embodiment, the bump structure 210 can be situated in two stable positions, the inner position or the outer position, based on the rigidity of the material of the bump structures 210, such as silicone.

[0032] Further, when the bump structure 210 is pushed inwards toward the container interior 11, the side wall (which may be connected to two adjacent first living hinges 114) of the movable bump structure 210 can be coplanar or roughly coplanar with the sidewalls 115 of the convolutions 112 and 113 as shown in Fig. 1G. On the other hand, the surface of the movable bump structure 210 can have an offset with the surface of the sidewalls 115 of the convolutions 112 and 113 when the movable bump structure 210 is indented.

[0033] Likewise, a user can push the indented bump structures 210 outwards to use the bump structures 210 to maintain the rigidity of the compressible portion 110. In an implementation, when a user expand the compressible portion 110, the bump structures 210 may pop out automatically due to the tension of the material of the compressible portion 110.

[0034] As shown in Fig. 1A, the movable bump structure may include a third living hinge 212 (such as, but not limited to, a fold, a cease, a channel, and/or a cutout) on an inner surface of the bump structure 210, and the third living hinge 212 allows the movable bump structure 210 to be indented along with the third living hinge 212. Exemplarily, the third living hinge 212 aligns with the at least one second living hinge 116 of the bellow body 111. The third living hinge 212 may extend from one end of the sidewall of the bump structure 210 to the other end of the bump structure 210. The third living hinge 212 may, exemplarily, be situated in the middle of the inner surface of the bump structure 210 and may divide the sidewall of the bump structure 210 into an upper sidewall and a lower sidewall. The upper sidewall and the lower sidewall can pivot on the third living hinge 212 when a user pushes the bump structure 210. Further, the movable bump structure 210 includes two end walls 214 at two opposite ends of the sidewall of the bump structure 210. The two end walls are connected to the sidewalls 115 of the two convolutions 112, 113 and the second living hinge 116. Each of the two end walls 214 defines three tips 216, the three tips 216 is respectively connected to the first living hinges 114 and the second living hinge 116. In one implementation, the sidewall of the bump structure 210 has a higher rigidity that the sidewall 115 of the compressible portion 110. Further in one implementation, the sidewall of the bump structure 210 is thicker than the sidewalls 115 of the convolutions 112, 113. Further in one implementation, the sidewall of the bump structure 210 is thinner than the sidewalls 115 of the convolutions 112, 113.

[0035] As shown in Fig. 1A and Fig. IE, the container 10 further comprise a lid base 310 connected to the compressible portion 110. The lid base 310 is configured to receive a lid 320. In one implementation, the lid base 310 is a frame to be affixed on the top of the container 10. The lid base 310 may have a higher rigidity than the compressible portion 110 and the container base 120. The lid base includes a hinge 312, and the lid 320 is pivotally connected to the hinge 312. The lid 320 is detachable from the lid base 310. The hinge 312 defines an opening 315 to receive a pivot 322 of the lid 320, and the opening 315 faces away from the lid base 310. Exemplarily, the lid 320 can rotate for approximately 270 degrees, and the lid 320 can be made of polypropylene. The lid base 310 further includes a protrusion 319 (as shown in Fig. IE), and the protrusion 319 is used to engage with the lid 320 to secure the lid 320 in a closed status. The lid 320 may have a corresponding protrusion or a concave 321 (as shown in Fig. IF) that fits with the protrusion 319 to engage with the protrusion 319. [0036] Additionally, as shown in Figs. 2A, 2B, and 2C, the lid base 310 includes a first skirt 314. The compressible portion 110 includes a gasket 117 and a second skirt 118. The gasket 117, the first skirt 314, and the second skirt 118 stack with each other sequentially. The gasket 117 touches the protrusion 324 on the bottom surface of the lid 320 when the lid 320 is closed. The gasket 117 and the lid 320, specifically the protrusion 324, seal the main opening of the container 10. Exemplarily, the gasket 117 and the protrusion 324 (as shown in Fig. 2D) on the lid are contoured to each other. Further, the gasket 117 is contoured with the lid base 310. The gasket 117 and the protrusion 324 may each form a closed loop.

[0037] Additionally as shown in Fig. 2C, the first skirt 314 forms one or more through holes 316 on the lid base 310, and the gasket 117 and the second skirt 118 are connected to each other by one or more connecting parts 317 in the through holes 316. The through holes 316 may be distributed around the periphery of the lid base 310. The connecting parts 317 are formed by a molding process, such that the gasket 117 and the second skirt 118 are formed together with the same material, such as silicone. The lid base 310 is thereby affixed with the gasket 117 and the second skirt 118 with the connection of the first skirt 314 with the gasket 117 and the second skirt 118. The lid base 310 is thereby affixed with the compressible portion 110.

[0038] For manufacturing, the container 10 can, for example, be made by an insert molding process. Specifically, the lid base 310 can be prepared first by a molding process, such as an injection molding. The lid base 310 can be made of polypropylene. Then, the body of the container 10, such as the container base 120 and the compressible portion 110, can be affixed together with the lid base 310 by insert molding. The container base 120 and the compressible portion 110 therefore can be formed in the same molding process. The lid base 310 has a wall 318, and the wall 318 surrounds the first skirt 314, the gasket 117, and the second skirt 118. That is, the geometry of the lid base 310 is larger than the compressible portion 110 and the container base 120.

[0039] In one embodiment as shown in Figs. 3A to 3F, the container 10 includes at least one valve or vent 400, such as a one-way valve or vent. When the container 10 is compressed, the valve 400 can discharge the air in the container 10 in reaction to the force is exerted on the container 10. Otherwise, the valve 400 remains closed when there is no sufficient air pressure from the container interior 11 to open the value, such that the air outside the container 10 does not easily enter the container 10. As an example, the food stored therein can thereby be preserved better.

[0040] Exemplarily, the valve or vent 400 can be configured as part of the compressible portion 110. For example, the valve 400 can be situated underneath the second skirt 118 of the compressible portion 110. The valve 400 can be situated next to the inner surface of the wall 318 of the lid base 310. The valve 400 may include a rib 424 and a pair of leaflets 420. The pair of leaflets 420 extend from the rib oppositely, and a thickness of each of the leaflets 420 gradually reduces along with the leaflet 420 in a direction extending away from the rib 424. Specifically, the end of the leaflet 420 attached to the rib 424 has the largest thickness, and the end of the leaflet 420 opposite to the rib 424 has the smallest thickness. The leaflet 420 can be in a shape of a triangular prism or a trapezoidal prism. This design facilitates the leaflet 420 to deform to allow the air to pass the valve 400 and discharge. The valve 400 and the leaflet 420 can be made of silicone to provide proper flexibility. The valve 400 and the leaflet 420 can be formed during the same molding process as the compressible portion 110. [0041] Further, the lid base 310 may define at least one channel 410 (as shown in Fig. 3C). The channel includes a first branch 412 and a second branch 414, where the first branch 412 and the second branch 414 are substantially perpendicular to each other. The first branch 412 defines an opening 416 of the channel 410 to the container interior 11, and the second branch 414 stacks with the pair of leaflets 420 of the valve 400. Exemplarily, the container 10 has two channels 410, which form two openings 416. The channels 410 can be in a T shape. When the air in the container interior 11 flows into the opening 416, the air flows along the first branch 412. Then the air is diverted into two paths when the air reaches the end of the first branch 412. The air then enters the second branch 414. The second branch 414 overlaps with the leaflets 420, such that when the pressure in the container exceeds a certain threshold, the air in the container 10 will push the leaflets 420 to deform and will be discharged as the valve 400 is opened. Otherwise, the leaflets 420 remain their original position when there is no sufficient air pressure from the container interior 11 to deform the leaflets 420, such that the air outside the container 10 does not easily enter the container 10. As an example, the food stored therein can thereby be preserved better.

[0042] In one embodiment, the first branch 412 aligns with the rib 424, and the second branch 414 aligns with the leaflet 420. Further, the leaflet 420 may extend outwards over the end of the second branch 414 to ensure that the second branch 414 is fully covered by the leaflet 420. That is, the length of the second branch 414 is smaller than the total length of the two leaflets 420 and the rib 424 along the longitudinal axis of the second branch 414.

[0043] In one embodiment, a ratio (H1/H2) of a height of the compressible portion 110 (HI) to a height of the container base 120 (H2), when the compressible portion 110 is fully expanded, is less than 2.0. In another embodiment, the ratio is less than 1.9. In still another embodiment, the ratio is less than 1.5 or 1.0. Further, in one embodiment, a ratio of the height of the container 10, when the compressible portion 110 is full compressed, to the height of the container 10, when the compressible portion 110 is fully expanded, is more than 40%, 45%, 50%, 55%, or 60%.

[0044] One embodiment of this disclosure provides a container, which comprises a lid base 310 and a compressible portion 110. The lid base 310 has a channel and is configured to receive a lid 320. The compressible portion 110 is connected to the lid base 310, and the compressible portion 110 includes a one-way valve in air communication with the channel. The components of this container of this embodiment can be selectively adopted in the implementation disclosed above.

[0045] One embodiment of this disclosure provides a container. The container comprises a lid base and a body. The lid base is configured to receive a lid and includes a first skirt 314. The body includes a gasket 117 and a second skirt 118. The gasket 117, the first skirt 314, and the second skirt 118 stack with each other sequentially. The body may include a compressible portion 110 and a container base 120. The components of this container of this embodiment can be selectively adopted in the implementation disclosed above.

[0046] As shown in Fig. 5 A and Fig. 5B, the above implementation can be implemented in containers of different sizes. The container may have a different length, width, and/or height as to the container 10. Likewise, the shape of the containers of this disclosure can be, for example, square, rectangular, circular, or any other shape, without departing from the scope of the present disclosure.
