The description relates to device retention assemblies. One example can include a bucket having an open end and defining a volume that contains electronic components. The example can also include a lid positioned over the open end of the bucket. A retention assembly can be configured to bias the lid against the bucket to seal the open end. The retention assembly can include a tab that is secured to the lid with a fastener that extends through the retention assembly into the lid without extending completely through the lid and does not contact the bucket.

A canister including a lid and storage canister. The lid incorporates a gasket that is overmolded onto the lid during its manufacture. The gasket is exposed on both the upper and lower surfaces of the lid in order to provide a non-slip surface at the top portion of the lid and a sealing surface at the bottom of the lid for sealing a storage canister.

The present invention relates to a packing unit in which a sealing function of the container unit is improved and a lid unit can be firmly fixed to the container unit, and a sealed container having it, when storing a variety of contents in a container unit. To this end, the sealed container includes a container unit having a containing space to contain contents, a lid unit opening and closing the containing space provided in the container unit, a packing unit sealing between the container unit and the lid unit, and a rotating and tightening unit formed to interlock when the lid unit is moved and rotated toward the container unit.

A container cover for storage container includes a rotary device, an outer cover member, an inner cover member, a first guide block, second guide block, a pumping piston and a piston seat so arranged that when the rotary device is driven by a user to rotate the first guide block, guide rods of the first guide block are moved along a first continuous wave-shaped track of the second guide block, causing the second guide block and the pumping piston to move alternatively up and to further pump air out of the storage container through an air-pimping hole of the piston seat to create a negative pressure. Further, a first spring member an upper rail seat can be provided to balance the movement of the pumping piston and to stabilize the rotation of the first and second guide blocks. A relief valve rod can be selectively used for giving a visual indication indicative of the presence of a negative pressure in the storage container.
