A vacuum-drawing lid can include a base frame with a first one-way valve, a piston with a second one-way valve, and a cylindrical cam with a sinusoidal groove formed on an inner surface thereof to drive reciprocation of the piston as the cylindrical cam turns. Turning the cylindrical cam in a first direction can drive the piston to translate in a first direction and actuate the first valve. Turning the cylindrical cam in a second direction can drive the piston to translate in a second direction and actuate the second valve.

The present specification discloses a collapsible food container. The container includes a wall portion with an outer surface having a substantially smooth shape. The wall portion is configured to bend from raised position to a collapsed position, with the food container being used to retain food in the raised position and being collapsed for storage in the collapsed position.

Aspects of the present invention disclose and describe embodiment containers for displaying, visualizing, and aroma sampling botanical materialssuch as tea, cannabis, and the like including a container body, lid, and lenswhich may have various shapes. In a preferred embodiment, lid is shaped to define a recessed area with scent openings permitting aroma sampling of a sample contained within. A removable plug is shaped to fit within the recessed area of the lid. The container body and lid, with removable plug fit within the lid, form an airtight chamber within. A botanical sample may be visualized through the lens.

The disclosure provides a container lid including a resealable closure mechanism. The container lid includes a lid housing having a recess, a rim, an opening, and a connector portion. The container lid additionally contains a sliding actuator that moves in a first direction and a second direction. Further, the container lid has a sealing mechanism that moves in a third direction and a fourth direction, wherein the third direction and the fourth direction are in a plane of movement which is perpendicular to the first direction and the second direction.

A valve assembly for use on a food storage container including an opening formed in the lid member, at least one air hole formed adjacent thereto, a valve member extending through the lid opening having a portion thereof extending over the at least one air hole when the valve member is in its closed position, the valve member being movable to an open position wherein the portion of the valve member extending over the at least one air hole is at least partially uncovered from the at least one air hole when a vacuum is generated within the storage container, and a vacuum release button engageable with the valve member and movable from a first position wherein the valve member remains in its closed position to a second position wherein the valve member is moved to its open position for releasing the vacuum generated within the storage container.

The invention relates to a vacuum-sealed container comprising: a container body (10); a container cover (20) having hinge portions (22); a handle (30) comprising a pair of rotating cylinders (31) having first ends rotatably coupled to respective hinge portions (22) of the container cover (20) and having channels (34, 35) to communicate with the container body (10), a pair of elevating bars (36) coupled to second ends of respective rotating cylinders (31) to be able to move upward/downward, and a connecting bar (37) for connecting the elevating bars (36), a ventilation channel (38) formed in at least one rotating cylinder (31) or in the elevating bar (36); a first check valve (40) that opens/closes first ends of the channels (34, 35) of the handle (30) as the elevating bars (36) of the handle (30) move upward/downward; and a second check valve (50) that opens/closes the ventilation channel (38).

A beverage container closure or lid that is adapted for closing an open end of a beverage container. The lid is selectively couplable to the beverage container and includes a selectively openable stopper that when closed, creates a fluid-tight seal between the beverage container and the environment. The stopper may be selectively opened by a user by the user pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the user releases the button. Thus, a user may open and close the beverage container closure using a single hand without the need to remove the beverage container closure from the beverage container.

An easy-opening end closure that may also be reclosed, suitable for joining to a container. A cover panel is bonded around its perimeter to an end panel with a rotatable lever interposed between them. To open the closure, a user applies force to the rotating lever to move it axially around an attachment point and progressively debond the seal perimeter. In this process, latching mechanisms ensure uni-directional movement of the lever relative to the shutter and joining of the two components at the end of the rotational sweep.

An easy-opening end closure that may also be reclosed, suitable for joining to a container. A cover panel is bonded around its perimeter to an end panel with a rotatable lever interposed between them. To open the closure, a user applies force to the rotating lever to move it axially around an attachment point thereby engaging integrated mechanisms to progressively debond segments of the perimeter seal.

A pressure relief cap includes a body engageable with a container and rotatable about an axis for coupling or decoupling the body from the container. The pressure relief cap also includes a handle and a motion control mechanism operable to selectively couple the handle to the body. The motion control mechanism includes a clutch plate moveable between an engaged position in which the clutch plate permits torque transfer from the handle to the body, and a disengaged position in which the clutch plate inhibits torque transfer from the handle to the body. The pressure relief cap also includes a relief valve for releasing pressure in response to elevated pressure within the container.
