Abstract: A dispenser for dispensing paste compositions comprising a piston movable in an emptying direction within a dispenser housing, and a stopper part for closing the piston adapted to be driven in sealing manner into the piston. A stopper seat is developed in the piston and the dispenser housing is evacuatable by an air vent zone located in the region of the stopper seat, the zone being defined by slots formed between the stopper seat and the stopper part which are interrupted by radial arms of the stopper part. The arms form two separate sections which lie one behind the other in axial direction, and which are separated from each other by a free space, and at least those arms which lie on a cross-sectional plane of one section are formed as tear-off arms.

One closure piece forms a lid having an outlet opening pre-sealed by a tear-off tab. The lid includes a skirt projecting into the jacket, and a gas vent opening which is open during the installation of the closure pieces to vent displaced gas, and is thereafter closed by securing an end of the tear-off tab thereover, or by deforming the lid material, or by placing a drop of hardenable plastic in the vent opening.

Abstract: A recipient having an axially upwardly open neck formed with at least one radially projecting neck thread is capped by fitting a circumferentially thermally shrinkable sleeve around a plug, fitting the plug into the open neck to block same, fitting the sleeve also around the neck over the neck thread, and heating the sleeve and thermally shrinking it circumferentially into tight engagement with the plug and with the neck and neck thread. The sleeve can be first fitted around the plug and then shrunk over the plug, after which the plug and sleeve are fitted together to the recipient, whereupon the sleeve is shrunk over the neck. Alternately the plug is fitted to the neck, then at the same time the sleeve is fitted around the plug and around the neck, and then the sleeve is heated to shrink it onto the plug and neck at the same time.

The disclosure is also of a novel method of assembling the closure of the invention in an air evacuated tubular container.

Abstract: An apparatus and method for automatically placing large plastic lids onto containers. Lids 24 are dispensed individually from magazine 11 onto slide 33. Each dispensed lid is individually retained at the bottom of the slide 33 for pickup by a container 41. The lid is urged onto the container by a pivoted roller 47 and further leveled by a roller 58 which is extended twice by a pneumatic piston to first contact a leading edge of the lid and to secondly contact a trailing edge of the lid. Thereafter a pneumatically operated lid securement means 61 comprising a convex plate 70' burps the air from beneath the lid and fully seats the lid on the container. The apparatus has various sensing means for sensing the depletion of lids from magazine 11, for sensing that a lid has been dispensed onto slide 33 and for sensing a container at the capping station. The sensing means control the various operations of the machine in proper sequence.

Abstract: An improved dispenser for cosmetic stick solids such as deodorants constructed to be filled in either normal or inverted position. This dispenser is cylindrical having walls of substantially uniform diameter, an open top, and substantially closed bottom. The dispenser is constructed so that the dispensing means is either pushed up manually, or propelled by a screw-mechanism. In the latter case a long screw is mounted in a central opening in the bottom, and continues along the axis of the cylinder. The cap of the dispenser may assume either of two forms, a snap-on type, or a screw-on type, each exhibiting an air-tight seal. The snap-cap is constructed to include a plurality of cams which operate in conjunction with similar members on the mouth of the cylindrical container to provide relative ease in opening and closing the snap-cap.The dispenser is designed to be filled in a conventional manner from the opening in the top, or, alternatively, from a hole in the bottom of the cylindrical container.
