Abstract: A device is disclosed for delivering insecticidal gel and other fluids from an aerosol can. The device has a first arm that docks to the aerosol can top. A second arm pivots relative to the first arm and has an adaptor tube that deflects the valve and forms a leak-proof connection channel for product being delivered from the can. The tube can alternatively be connected to a piston type tube (to refill it), or it can be linked to a delivery straw to directly deliver the fluid.
Abstract: The present invention provides a pliable mop bucket insert, which can be adapted to fit various buckets and wringers with different geometries. The present invention also provides a device for receiving dirty washing liquid from a mop and containing clean washing liquid for wetting a mop separately, which includes a main container for containing the clean washing liquid, an insert being removably attached to the bucket for receiving the dirty liquid, and a wringer located inside the insert and supported by the bucket. A flexible bag is further provided with the insert to contain dirty washing liquid.
Abstract: This invention provides an aqueous coating composition, more particularly an aqueous floor finish composition, comprising water, at least one polymeric film forming agent, and a plasticizing agent, wherein the improvement comprises at least a portion of the plasticizing agent being at least one tertiary alkyl monocarboxylic acid having an average of from about 6 to 30 carbon atoms per molecule. Such compositions have one or more improved properties such as increased hardness as compared with the same compositions using only conventional plasticizers such as tributoxyethyl phosphate, improved wetting of the substrate by the composition during application, improved coating film leveling, improved multiple coat gloss development, and improved resistance to wear, black heel marking and scuffing.
Abstract: A port system for a blow molded intravenous solution container in which microbial contamination is prevented upon administration of the solution. The port system includes an integrally formed tube projecting outwardly from the container with a pierceable diaphragm positioned over the entry portion of the tube. Preferably, with respect to the tube entry portion, the diaphragm is concave, and may be made thinner in the center to facilitate proper placement of a piercing pin. In one embodiment, the port tube is inwardly flared adjacent the diaphragm so that as the piercing element is pushed through the diaphragm, the remnants of the pierced diaphragm can be pressed into the flared portion of the tube.
Abstract: A dual compartmented container containing a medicament in one compartment and a diluent in the other with an actuating piercing element operable from outside the container. Mixing of the medicament in one compartment with the diluent in the other is accomplished by moving the piercing element inwardly into the container to pierce a primary diaphragm which seals one of the compartments to outside atmosphere as well as a secondary diaphragm which seals the compartments from each other. The piercing element is constructed and arranged to afford fluid communication between the compartments after it pierces both diaphragms. Intermixing of the contents of the container can thereby be made internally thereof.
Abstract: A container for liquids, preferably sterile liquids comprises a hollow body constructed of plastic material having a plurality of tubular ports integrally formed and extending therefrom. Each port has a quantity of plastic material integrally formed as a diaphragm within the port so as to seal the container. In a preferred embodiment, at least one of the ports has a resealable septum sealed within it. The diaphragm is positioned between the septum and the liquid within the container so as to prevent deterioration of the resealable septum caused by exposure to the liquid. Both the resealable septum and the diaphragm are constructed of a material which is penetrable by a hypodermic needle for use in administering sterile solutions. A removable twist cap is integrally formed about and seals the end of each tubular port.
Abstract: A tamperproof sterile solution closure system which will permit the machine assembly of the closure cap to the container without engagement of the threads of the cap with the container threads. The screw type cap member has internal threading, a tear-away portion and a skirt portion. The container has an abutment surface for sealable contact with the skirt portion and in a position such that the threads in the cap and on the neck are not engaged. To activate the closure, a tear-away portion is removed which will allow the threads to engage. Simultaneously, a contact portion on the cap will engage a weakened flange in the neck to cause it to be separated. A projection extending from the cap is positioned in an annular recess in the cap to serve as a captive means for the separated dome portion of the cap for replacement purposes.
Abstract: A compartmented and collapsible container for sterile components which has at least one separate compartment for each component, yet will permit the intermixing of the components upon the breaking of a frangible member which separates the compartments. The compartmented container is specifically constructed for use with two solutions which are normally incompatible when mixed. The container herein described permits the two incompatible solutions to be sterilized in a disposable, flexible container. At the time of usage, the two materials can be readily intermixed in the same container and administered therefrom, such as with the usual intravenous administration equipment. An important feature of the container is a frangible member which is sealed to the container in a unique manner between the compartments, yet is readily fractured to permit the free flow of materials between the compartments.
Abstract: A disposable intravenous pump chamber assembly for an intravenous administration set which substantially reduces the problem of air bubble entrapment so that the amount of intravenous fluid delivered is effected in an accurate manner. The pump chamber assembly is specifically constructed to be utilized in conjunction with a diaphragm-type pump with external valving. The pump chamber cassette is held in the pump in a unique manner and includes a porting and fluid delivery arrangement which reduces the problem of air entrapment in the pump chamber.

Abstract: A disposable intravenous administration set for use with a single pump chamber wherein a primary and secondary set are combined into a single I.V. pump set. The dual capacity set would be utilized in conjunction with an I.V. pump having a capacity for at least two distinct flow rates. The primary and secondary portions of the set are interconnected through a Y-type backcheck valve in the usual manner with the secondary source of liquid placed at a higher level than that of the primary. With the secondary set connected to a secondary source of liquid the pump will be set at a flow rate faster than that for the primary set. After the secondary source of liquid is depleted, the primary source will then be administered as the pump will automatically convert to the slower flow rate.
Abstract: An apparatus which can clean powdered material from a filled pouch during a filling operation and at the same time introduce an inert atmosphere into the pouch prior to sealing. The apparatus includes a pair of wheel members mounted on a shaft for opposite rotation, the wheels having apertures which will eject inert gas in an opposing direction. The wheel members serve the dual function of blowing powdered material from the top of the filled pouch while at the same time introducing an inert atmosphere therein. The wheel assembly is especially suited for a high speed filling operation such as that commonly found in conjunction with a multiple stationed and rotatable filling apparatus.
Abstract: A clear, flexible, thermoplastic material capable of being processed into hollow shapes by conventional thermoplastic processing methods and subsequently autoclaved, comprises four components: from about 45 to 70% by weight of a polyolefin polypropylene, including its copolymers, admixed with from; about 5 to 25% by weight of an ethylene loweralkyl acrylate polymer from; about 10 to 40% by weight of a thermoplastic ethylene butylene block copolymer elastomer having terminal polystyrene blocks; and from 0 to 15% of a high-boiling point petroleum distillation byproduct as represented by mineral oil. The above material is particularly desirable for manufacturing medical liquid containers such as autoclavable, flexible, collapsible, intravenous solution containers.
