Abstract: A method for sealing and cutting of a flexible material for forming a flexible container comprising a product volume and at least one structural support volume can include feeding at least two flexible material into a sealing apparatus comprising a sealing surface and an opposed anvil surface; contacting a seam region of the at least two flexible material with the sealing surface to form a seal in the seam region and cut the seal to form a seam in a single unit operation. The seal defines one or both of at least a portion of a boundary of the product volume and at least a portion of a boundary of the at least one structural support volume.

Abstract: Cleaning sheets comprise an additive that is selected to enhance the pick up and retention of particulate material from surfaces, while minimizing the amount of residue left on the surface being cleaned. If the type of additive and level of additive on the cleaning sheet are not carefully selected, the sheet will leave a residue on the surface being cleaned resulting in filming and streaking of the surface that is unacceptable to consumers. The additive is preferably selected from the group consisting of a wax, an oil, and mixtures thereof. Cleaning implements comprise a mop head having a resilient bottom surface, a portion of which preferably has a substantially smooth curved profile or crown which engages a removable cleaning sheet.

Abstract: A sprayer with a water purifier, a valve system, and a selector switch for the same are disclosed. In one non-limiting embodiment, when the sprayer is in use, the sprayer includes a purifier for purifying water. The sprayer may be compact and ergonomic. The sprayer may include a valve system that provides a selection of water flow paths and/or nozzles or other output mechanisms for the sprayer, and a selector switch for controlling the valve system. In certain embodiments, the sprayer is provided with a multiple position selector switch that can be controlled by one of the operator's fingers, or by the operator's thumb so that the operator can use the sprayer and select the sprayer setting with one hand.
