Abstract: A method of loading stacked strainers in a dispenser while minimizing strainer contamination is disclosed. The method includes providing a stack of strainers that is enclosed in a protective material to form a pod, placing the pod within a dispenser, and removing the protective material from the pod of strainers while the strainers are in the dispenser. The strainers dispensed from the thus loaded dispenser avoid being contamination during loading. The protective material may be perforated to facilitate removal from the stack, and include an extended portion to be grasped during removal from the dispenser.

Abstract: An improved liner is provided for use with a liquid container system for a spray gun. The liquid container system includes a cup, a ring disposed on a lip of the cup, the liner which is supported within the cup by the ring, and a lid which closes the open end of the liner and connects to the spray gun. The liner includes an open end, a closed end opposed to the open end, and one or more longitudinally-extending stiffening ribs that extend across an apex of the liner closed end.

Abstract: A liquid container assembly for a spray gun can include a ring, a collapsible liner, and a lid for closing the open end of the liner. The ring can include a peripheral flange, a ring recess, an inner wall, and at least one rib segment extending from the inner wall. The collapsible liner can include a liner side wall formed with an open end and a liner lip at the open end. The liner can be is insertable through the ring such that the liner lip is received and supported by the ring recess. Further, the liner can be collapsible during use as liquid is removed from the liner. The lid can include at least one tab that can extend from an outer circumference of the lid. The tabs can engage the rib segments to threadably attach to the ring.

Abstract: A liquid container system for a spray gun. The container system includes an outer cup, a collapsible liner for holding a liquid to be sprayed, and a lid for closing the liner. A mounting ring may be used in the cup to make locking engagement with the lid. A lip at the open end of the liner is supported by the mounting ring. A removable lid with a liquid outlet is inserted into the mounting ring, clamping the liner lip to the mounting ring and providing for leak-free operation of the system. Alternatively, the lid may include a cylindrical portion for making sealing engagement with the open end of the liner and projection threads for locking the cup. An adapter connects the liquid outlet of the lid to the spray gun. A collar may facilitate locking engagement of the adapter with the lid.

Abstract: A connector system for attaching a liquid container to a spray gun includes a lid with a liquid outlet and an adapter that connects the outlet with the liquid inlet port of the gun. The lid includes interlocking tab assemblies for releasably attaching the adapter to the lid. The connector system combines with an outer cup, a ring for insertion into the mouth of the cup and a collapsible liner for insertion into the ring to form a liquid container system. The ring includes internal threads that cooperate with a peripheral flange on the lid to lock the lid to the ring, securing the lip of the liner. The lid includes a flexible gasket to form a liquid tight seal with the liner. The lid-liner-ring forms a liquid tight unit that may be inserted into and removed from the outer cup while containing a fluid such as paint.

Abstract: A flat-folding mask includes a filter layer forming a rim. The filter layer has first and second side panels extending from the rim. A substantially centrally located front panel bridges the first and second side panels, the front panel being substantially flat. The filter layer further includes a fused portion that is seamless and spaced from the rim. Triangular pleats may add support to the side walls and increase the effective filtration area of the mask.

Abstract: A one-way fluid valve may include a valve base having a central portion with a post and an outer portion having a seat, a diaphragm having a central portion with an opening for receiving the post of the valve base, the diaphragm having a diameter of at least about 1.375 inches, and a cover having a retainer for securing the diaphragm to the valve base at the central portion of the valve base.

Abstract: A respirator system has a vapor filter which includes a body for holding a vapor filter media, a first integral male connector for attachment to a particle filter, and a second integral female connector on an opposing side for connecting to a respirator mask. The particle filter has a complementary female connector and the mask has a complementary male connector for attachment to the vapor filter body. Alternately, a circumferential lip of the vapor filter and a sealing surface or a retainer sealingly attach a particle filter pad to the vapor filter. A method of assembly includes providing a vapor filter with an integral connector for attaching to a particle filter, providing a complementary connector and connecting the vapor filter to the particle filter.

Abstract: A strainer blank comprises a flat sheet having a plurality of cutouts including a cutout adapted to define a strainer portion at the apex of a cone formed from the blank. Strainer material positioned over the cutouts defines a convex rear end at the apex which is folded during formation of the conical strainer to form a multi-ply elongated seam which adds strength and provides a surface area for adhesively uniting the strainer material.

Abstract: A blade scraper has a hand grip casing with a blade storage compartment and a slide mounted in a chamber of the casing for holding a razor blade and permitting retraction of the razor blade into an inoperative position and sliding movement to an operative position with the blade in a scraping position exposed outside of the chamber. A pressure sensitive locking button acts to lock the blade in the inoperative position or the exposed position. A safety button is interconnected with the slide so that pressure must be applied to two actuating buttons in order to expose the blade thus making it difficult for small children to accidentally place the scraper in a mode of operation dangerous for handling. The slide carries a safety dowel for locking the blade compartment when the blade is locked in its inoperative position.
