Abstract: Disclosed is various embodiments of a self-heating or self-cooling container with a number of improved features in overcoming the problems associated with existing containers, including, but not limited to, an improved breaking device designed to maximize the mixture and reaction between different reactants, an insulating lip to prevent heat loss in the heating process, a simple and efficient design of the container, and enhancements in manufacturing and assembling a self-heating or self-cooling container.

Abstract: The invention comprises a transparent, molded undercap which fits over the open end of a lipstick type case from which a lipstick or other similar waxy mass is propelled and which engages the shoulder of the case normally engaged by the lipstick cap when it is in place. The undercap is sized to fit snuggly within the lipstick cap yet permit the cap to be removed while the undercap remains in place over the lipstick. Preferably, the open end of the undercap has a size and shape which is substantially identical to that of the cap so as to form an even closure with the lipstick case whereby a tamper indicating or resistant means, such as an adhesive tape or a shrink band, may be applied across the juncture between the undercap and the case to secure the undercap in place and seal the lipstick. In this manner, the lipstick cap may be removed from the lipstick case to view the lipstick while the undercap remains in place to protect the lipstick.

Abstract: A blister package for a cosmetic article is disclosed which provides a means to include and protect an applicator while permitting the viewing of the cosmetic. The package comprises a support panel on which are mounted first and second blisters adapted to confine a cosmetic applicator and article, respectively. The first blister is mountable on the support panel confining the applicator and providing support for the cosmetic article while protecting the applicator from crushing and contamination. The second blister is mountable over the first blister, and the cosmetic article supported thereon, in a manner which allows the cosmetic article to be opened and the cosmetic therein viewed while preventing access to the cosmetic.

Abstract: An improved applicator for soft materials includes a cartridge section and a relatively rotatable body section, the soft material being contained within the cartridge section and a plunger being provided to advance the soft material. The improvement resides in providing an assembly within the applicator body to prevent the inadvertent separation of the cartridge section from the body section. In a preferred embodiment, this assembly comprises a clutch means between the rotatable body section and the plunger whereby rotation of the body is transmitted to the plunger to advance and retract the plunger and associated soft material, the clutch means being designed so as to disengage before the plunger is retracted to the point at which it would forcibly separate the cartridge from the body.

Abstract: An improved cosmetic package, particularly for eye make-up such as mascara, comprising a container, a cap having an applicator extendable into the container and a wiping body within the neck of the container. The package is particularly suited for applicators having an irregular cross-section and provides for threaded cooperation between the cap and container by a construction wherein the cap and applicator are relatively rotatable about their common longitudinal axis. An alternative construction provides for the applicator to be fixed within the cap and the wiping body to be relatively rotatable with the container about their common longitudinal axis. These constructions allow applicators with irregular cross-sections to be used in containers where the cap and container attach by means of cooperating threads.

Abstract: The actuating lever of the dispenser has a rigid valve flap integral therewith which covers the spout outlet to close the same when the actuating lever is in its normal, undepressed position but which then lifts off the outlet to open the same when the lever is depressed in a pumping stroke. One embodiment employs a reciprocable pumping piston at one end of the dispenser body and a free-floating take-up piston at the opposite end of the body which responds to the evacuationof material within the pump chamber to take up the space otherwise occupied by the evacuated product. Another embodiment utilizes a pumping piston which starts at the lower end of the dispenser body and is progressively drawn up toward the opposite end during successive pumping strokes by a rod connected to the actuating lever.

Abstract: The plunger of the pump has a radially extending lug near its upper end which can be inserted down into a notch in the stationary pump collar when the plunger is fully depressed, so that when the plunger is then rotated in a clockwise direction relative to the collar, the lug is brought under an overhanging ledge on the collar to releasably lock the plunger in its fully depressed position. In order to deter unlocking, the lug of the plunger and the interior wall of the collar are provided with mutually interengageable structures that permit the lug to be rotated substantially without significant resistance into a final or fully locked up position against a shoulder beneath the ledge but to be held in such fully locked up position against unlocking movement unless substantial, counterclockwise-directed force is applied.

Abstract: The pump is clamped to the top wall of a container closure by a pair of opposed, upper and lower clamping surfaces on the pump body which position the body to project down into the container. The lower clamping surface takes the form of a circular flange which is integral with the pump body and which is itself normally clamped between the top wall of the closure and the upper edge of the neck of the container when the neck is only slightly larger than the pump body, thereby preventing rotation of the body when the pump plunger is rotated to either lock or unlock the same from a fully depressed, stored position. When the pump is used on a large closure having a wide neck whose upper edge therefore fails to clamp against the pump flange, the pump body will nonetheless be held immobile by a series of flat surfaces therearound which matingly interlock with complimentally configured flat edges in the closure opening through which the pump body extends.

Abstract: The plunger of the pump has an axial lock by which the plunger can be locked down in its fully depressed position during periods of non-use and a rotary lock for preventing inadvertent rotation of the plunger out of its locked down mode. The rotary lock includes a pair of yieldably spreadable arms which circle the collar of the pump and latch against one another in overlapping, embracing relationship so that the lock is held tightly on the collar against rotation relative thereto. A locking bar integral with the arms and of essentially rigid construction projects up out of the plane of curvature of the arms and has a saddle-like notch at its uppermost tip which complementally receives a portion of the spout associated with the discharge head of the plunger, thereby rendering the plunger rotatively immobile relative to the collar.

Abstract: The plunger may be locked down after a full depression stroke so that the overall height of the pump assembly and the container with which it is associated can be significantly reduced. A special valve component loosely encircling the plunger and slidable with friction along the interior surface of the barrel is initially positioned during factory assembly in a closed position covering vents in the sidewall of the barrel, thereby blocking the undesirable ingress of liquid into the barrel above the piston should the container be laid on its side during shipment or other handling. Upon the first unlocking upstroke of the plunger to its extended position, a shoulder on the plunger lifts the valve to an open position so the vents can function properly to introduce ambient air into the container replacing pumped-out product.
