A food-storage container includes a container body defining a storage area and a rim. A removable lid is connectable to the rim to seal the storage area. The lid defines a vent hole. A latch assembly of the container has a latch and a vent flap. The latch is pivotally attached to the lid and is configured to engage with the container body to secure the lid to the rim when in a latched position. The vent flap is pivotal relative to the latch between an open position in which the flap is spaced from the vent hole and a sealing position in which the flap seals the vent hole.

A locking mechanism for locking an upper cover of a container to a side plate of the container, the container comprising a base, the upper cover and the side plate, the upper cover being provided with an edge guard; the locking mechanism comprises a lock hole formed on the exterior of at least one of the side plate and a groove formed on the upper cover; an end of the locking element is mounted in the groove; the other end of the locking element is provided with a lock; the lock passes through the edge guard and extends into the locking hole in a direction perpendicular to a direction of the side plate to securely lock the upper cover to the side plate; the driving element is mounted in the groove and used to return element is mounted in the groove and used to return the mechanism, transportation and storage cost are reduced, and labor of operators is saved.

The present invention relates to a barrel lid, such as a wood wine barrel lid, that inhibits and withstands warping and/or deformation. In one embodiment, the anti-warping wine barrel head comprises a plurality of adjacent slats, a plurality of staves where at least one stave disposed between each pair of adjacent slats, a plurality of grooves disposed on a top and/or bottom surface of the barrel head where each groove is oriented at an angle with respect to the plurality of slats, and a plurality of rods disposed in the plurality of top and/or bottom surface grooves where at least one rod is disposed in each of the plurality of top and/or bottom surface grooves. In some embodiments, staves are double flanged or rectangular, and rods have a half-round cross-section or triangular cross-section. In other embodiments, a gasket may span the periphery of the barrel lid, for example, along a lip thereof. In some embodiments, a locking ring is utilized to secure wine barrel lid to the container or drum.

The technology disclosed herein includes methods and apparatus of a childproof storage container, which includes a lid and a base portion with seesaw-style latches. The seesaw-style latches are configured to unlock a childproof storage container in a locked position upon simultaneously release. Each seesaw-style latch may include a flared end. In a locked position, the childproof storage container may be unlocked and opened upon depression of the flared end of the seesaw-style latch, which rotates the seesaw-style latch from the lid. Each seesaw-style latch may include a standing rib to prevent over-rotation of each seesaw-style latch and/or a chamfer to facilitate closure. The base portion may include a base portion flange, which includes a plurality of female recesses to receive the plurality of male teeth of a lid flange. The base portion and the lid may include opposing walls that interlock during a closed position and/or a gasket for sealing.

A vacuum cleaner includes a canister defining a debris chamber, a lid mounted to a top of the canister, a debris inlet defined by one of the canister and the lid, and a lid latch rotatably connected to the canister. The lid latch is rotatable between a first position, in which the lid latch is disengaged from the lid, and a second position, in which the lid latch engages the lid to secure the lid to the canister. A bottom of the lid latch is spaced from an exterior surface of the canister to define a handle opening that allows a user to insert their fingers into the handle opening and grip the bottom of the lid latch.
