A sealable container system contains a body and a lid assembly. The body includes an internal volume defined by a bottom and side wall(s) and divot(s) with a cavity at an upper edge of and in an inside surface of the side wall. The lid assembly includes a lid with outer and inner walls at its bottom side with a channel in-between. A gasket couples to the lid with a wall portion residing within the channel and a lip outside the channel. When the lid assembly is pressed into the body, the lip of the gasket abuts the divots and forms a gap with the side wall, where air in the internal volume exits through the gap. When the lip travels past the divots, the lip fully seats against the inside surface of the side wall, and negative air pressure is imparted to the internal volume of the body.

A low-profile dust collector assembly incorporates a low-profile cyclonic separator into a lid for a dust collection bucket. An outer lid ring can be formed of coffers that add strength to the lid and also reduce swirl in the air below the lid. The cyclonic separator has a shell rising from an inner circumference of the lid ring and has a horizontal inlet tube and central vertical outlet tube. A baffle for the separator includes a baffle plate fitted within the inner circumference and a turret of vertical members arranged with a top ring that fits onto the outlet tube. This compact arrangement has improved performance in airflow and dust separation. A spring clamp assists in fitting onto buckets over a range of diameters, and a pair of circumferential gaskets at right angles to one another form an air-tight seal.

A pulp-molded cup lid with a leakproof structure is introduced in accordance to the present invention. The leakproof structure is constructed jointly by both of an annular hook and a bulger of an annularly peaked saddle, and an upward-bent bottom of an annularly caved channel, all of which are located respectively at different standard position angles to jointly clamp an annular roll side of a cup body in a manner of making the annular roll side being tightly snapped-on, water-sealed and movement-restricted within a movement-restricting space of the annularly peaked saddle, thereby effectively preventing a fluid, stored within the cup body, from spillover, wherein the standard position angle where the bulger is located is an acute angle.

A forming structure for the internal snap ring of a pulp molded cup lid is disclosed. When manufacturing the pulp molded cup lid, the pulp suction mold sucks a pulp layer and sends it to a hot press upper mold for clamping and squeezing to shape the pulp layer into a primary blank, meanwhile producing an internal snap ring part on the primary blank. After subsequent hot pressing and shaping, the finished product of a pulp molded cup lid will have an integral internal snap ring structure. Comparing with the prior art, the present invention omits a second operation (processing), and the preparation of a mold for the second operation (processing). Therefore, the present invention can save manufacturing cost and time.
