Abstract: The invention is a single use container having an outer enclosure and an inner compartment isolated therefrom and is advantageous for the machine washing of laundry using detergent compositions having mutually incompatible constituents. Through an opening, the inner compartment receives a constituent of a detergent composition, such as a peroxidic additive. The outer enclosure receives another constituent of the detergent composition through a separate opening. For storage and for sale, a hood crowns the upper part of the container sealing the openings of the enclosure and compartment, thereby isolating the constituents of the enclosure and compartment. With the hood removed, the container is inserted into the drum of a washing machine. Simultaneous and gradual release of the constituents within the enclosure and compartment occurs during the washing operation.

Abstract: An improvement to a wide mouth container for powdered or granular products is disclosed. Attached to the neck of the container in a spaced relationship are two flat, lens-shaped projections having opposed surfaces generally normal to the container axis. Between the projections a dispensing slot is formed which is useful to effect dispensing by pouring. Alternatively, the size and spacing of the projections allows a spoon to be inserted into the container neck for dispensing the product. The projections do not interfere with the sealing means which closes the container.

Abstract: A reclosable dispensing package which has a thin plastic fitment mounted over a cutout area in the closure flaps of a seal end carton. The fitment is affixed to the outer (last-folded) major flap. When the carton is flattened tubular form, the caliper of the fitment-equipped closure flaps is minimized by providing a second cutout area in the inner (first-folded) major flap, sized and located to receive a projecting end of the fitment therein. Minimizing caliper permits shipment in more compact form and enables packing machine operators to place greater numbers of cartons in the machine hoppers.

Abstract: An improved cutting sleeve for the removal of flash from thermoplastic containers is disclosed. When used in conjunction with a blow-pin the cutting sleeve is movable relative to the blow-pin. In a preferred embodiment the cutting sleeve comprises two portions of different diameter. Use of the cutting sleeve results in an improved finish of the container neck.

Abstract: A dispenser for a product is described which incorporates a follower piston slidably mounted therewithin. The dispenser comprises an axially extending bore of a tubular container body for housing a product to be dispensed and having an upper end from which the product is dispensed and an open lower end. The follower piston is slidably mounted within the lower end of the bore of the container body to support the product thereabove. The piston is constructed of resilient material and comprises a face portion adapted to contact the product and a peripherally attached sidewall. The sidewall further comprises at least one integral peripheral contact band conforming to the shape of the cross section of the bore, and is adapted to virtually resiliently extend or contract in response to axial forces exerted on the face portion with such change in length resulting in an inversely proportional virtual change in lateral dimension of the peripheral contact band.
