A storage bag includes at least one zipper profile provided adjacent to an opening to the interior of the bag. The at least one zipper profile has opposing closure elements that respectively interlock with each other. The storage bag also includes a slider with at least one opening member and at least one detent on at least one end of the bag. The at least one detent is configured to engage with the at least one opening member of the slider to provide a leak-proof end seal.

A zipper for a reclosable bag includes a first interlocking element, and a second interlocking element. The first interlocking element and the second interlocking element are configured to cooperate to selectively open and close the zipper. One or both of the first interlocking element and the second interlocking element are formed of at least 85% repulpable material.

Dual-closure weather barriers that are configured to selectively seal an opening of a bag or enclosure. When sealed, the dual-closure weather barrier is configured to prevent an ingress of water into an interior volume of the bag or enclosure. The dual-closure weather barrier includes an outer sealing mechanism configured to form an outer seal of the opening and an inner sealing mechanism configured to form an inner seal of the opening. The dual-closure weather barrier is configured to be selectively transitioned between a fully sealed configuration and an unsealed configuration. When the dual-closure weather barrier is disposed in the fully sealed configuration, the outer sealing mechanism forms the outer seal, the inner sealing mechanism forms the inner seal, and the outer seal is maintained spaced above and away from the inner seal and an upper surface of the fabric bag relative to the interior volume.

The present application discloses a paper packaging bag with a ziplock, which comprises two bag sheets formed by folding a paper material, a ziplock, and two paper connecting strips. The side edges of the two bag sheets are connected to form a containing cavity; the ziplock is fixed at an opening of the containing cavity via the two paper connecting strips. Wherein, each paper connecting strip comprises a paper strip, a hot-melt adhesive layer and a film layer. The hot-melt adhesive layer is used for hot-press bonding with the bag sheets, and the film layer is used for hot-press bonding with the ziplock. The paper packaging bag with a ziplock realizes the combination of the ziplock and the paper bag by means of the paper connecting strips, thereby improving the usage convenience of the paper packaging bag and achieving better environmental protection.

A power tool having a power tool housing, a motor, a tool moved relative to the housing by the motor, a fan rotated by the motor such that a fluid flow with debris generated by tool is moved into the fluid inlet by the fan and through the discharge outlet, and a filter that is removably attached to the power tool housing. The power tool housing includes a fluid inlet and a discharge outlet. The filter includes a filter media for separating the debris from the flow of fluid. The filter media defines a collection container for storing the debris. The filter also includes an opening through which the flow of fluid with the debris enters the collection container, and a valve that is moveable between a closed position, in which the opening is closed, and an open position, in which the opening is open. The valve includes a duckbill check valve.

A lock includes: a base, an accommodating slot arranged on the base, and a movable plate fitted in the accommodating slot; wherein at least one deformation block, which is configured to be jammed into the accommodating slot, is set on the movable plate; at least one restriction block, which is configured to be locked in the accommodating slot, is set on the movable plate; a lever plate is provided on the base, which is configured to release the deformation block and thus releasing the movable plate; the lever plate comprises a working part, a connecting part and a pressing part, wherein the connecting part is pivotally coupled to the base. The accommodating slot on an external side of the base is used to lock the movable plate, and the lock can be opened only by pressing the pressing part.
