  • Patent number: 5522942
    Abstract: A synergistic cleaning composition has been discovered comprising an aqueous solution a quaternary ammonium compound component; a nonionic surfactant component; and a glycol ether solvent. Surprisingly, the combination of the quaternary ammonium compound component, the nonionic surfactant component, and glycol ether solvent provides a synergistic effect where the cleaning composition functions with a low level of quaternary ammonium compound component while still maintaining at least one of the following desirable properties, as follows: an acceptable cleaning efficacy; a low level irritation or toxicity profile; and/or a broad spectrum antimicrobial activity.

  • Patent number: 5507389
    Abstract: A stackable container useful for containing premoistened wipes therein includes a bottom having a pair of circular recesses and a lid having a pair of circular projections in alignment with the circular recesses so that the container may stack with similar containers. Each container is twice as long as it is wide so that the containers may stack in a staggered configuration, extending either parallel or perpendicular with respect to one another. The lid of the container is unitary with a rim and pivots with respect to the rim on a living hinge. A raised floor with a gutter therearound is provided at the bottom of the container for supporting a stack of moist wipes, wherein the edges of the lowermost wipes remain immersed in moisture which pools in the gutter in order to keep the stack moist.

  • Patent number: 5496858
    Abstract: Aqueous disinfectant concentrate which includes succinic dialdehyde, glutaraldehyde and/or formaldehyde, one or more alcohols of limited water miscibility and optionally usual auxiliaries. By diluting with water, a working solution can be prepared from the concentrate. The advantages of the new disinfectant concentrate or disinfectant are the reduced development of odor, an improved material compatibility, an improved microbicidal effectiveness and a clearly increased storage-stability. Furthermore, the activation usual up until now with disinfectants based on aldehyde is superfluous. Preferred application fields are surface and instrument disinfection.

  • Patent number: 5433350
    Abstract: A pump apparatus for dispensing a selected one of a plurality of liquids includes a pump housing containing a pump which is fixed to a container having a plurality of compartments, each accessed by a separate dip tube. The dip tubes each communicate with bores through a base disposed at the top of the container. A thumb wheel with a single bore is rotated about a central access to align the single bore with the selected one of the dip tubes and the single bore is connected to the pump via a crank-shaped connecting tube. Preferably, the thumb wheel is accessed through a window in the pump housing and has indicia thereon to indicate which of the liquids has been selected for dispensing by the pump.
