    Abstract: Pre-moistened wipes that include one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like are described. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes are specifically tailored to include a pore size distribution characterized by pores having a size from 300 μm to 400 μm, which is larger than the pore distribution characteristics of existing wipes. Such characteristics increase release of a quaternary ammonium compound to a target surface, providing improved microefficacy, without the need for any cationic biocide release agents such as latex or a cationic salt.

    Abstract: Plastic containers exhibiting reduced plastic resin usage, while maintaining a specific gravity of below 1.0, so as to allow their quick and easy separation using floatation techniques during recycling. Within a layer or portion some of the plastic resin of the container body may be replaced with an inorganic mineral filler material, while within another layer or portion of the plastic container, the plastic material (e.g., polyethylene, polypropylene) may be foamed. The fraction of mineral filler material that may be included within the polyethylene may thus be increased beyond that previously possible while maintaining the specific gravity below 1.0, by also foaming a layer or portion of the polymeric material, so as to create voids therein. This allows significantly less resin material to be employed, while maintaining strength characteristics of the plastic container so as to be at least comparable to existing plastic containers not including such mineral filler materials.

    Abstract: The present invention is for wipe dispensers for dispensing interconnected wipes. An exemplary wipes dispenser may include a container body and a removable lid forming an interior region into which a plurality of interconnected wipes may be disposed. Pulling on a lead end of a lead wipe causes a following wipe to also be pulled and follow the lead wipe. The removable lid may cover a portion of a container aperture (e.g., an open top of the container body). A landing member in the lid covers a portion of the container aperture by extending from a top rim of the container body toward the middle of the interior region. The landing member may form an angle with a substantially vertical exterior wall of the container, where the formed angle may be less than 90°. In an embodiment, the landing member may include a concavely shaped portion. The landing member may include one or more fingers.

    Abstract: In one example, a wipe dispensing system includes a housing that defines an internal wipe storage area, a lid rotatably connected to the housing, a fluid reservoir disposed within the housing, and a pump in fluid communication with the fluid reservoir. A fluid discharge manifold is in fluid communication with the pump and is arranged proximate to a portion of a wipe dispensing path. The lid is operably disposed with respect to the pump such that depression of the lid causes discharge of fluid from the pump through the fluid discharge manifold, and also causes partial dispensation of a wipe from the housing.

    Abstract: A spray dispensing device including a first chamber defined by a container, a bladder contained within the first chamber that houses a fluid composition (e.g., a bleach composition), and an actuator in fluid communication with the first chamber so as to allow dispensing of the fluid composition from the bladder when the actuator is actuated (e.g., pressed). A pressurized composition may be contained within a second chamber, which acts as a pressure control device. The pressure of the pressurized composition may be in a range of from about 70 psi to about 150 psi. An outlet valve may provide selective fluid communication between the pressure control device (i.e., the second chamber) and the first chamber.

    Abstract: The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency. Also provided are means to form stable associative polyelectrolyte complexes in aqueous solutions having R values from about 0.10 to 20, including near stoichiometric R values approaching 1, being the ratio of charged groups present on the component polyelectrolytes employed.
