Abstract: A one-piece container closure with a collar, stiff planar triangular leaflets attached by linear hinges to the collar, and thin flexible foldable webs attached to and extending between the leaflets. The leaflets are flat with the webs folded beneath in closed closure position. The leaflets are pivoted upwardly with webs unfolded therebetween in open position. An integral cap is attached to the collar by a snap-action bow-tie hinge. A central pin on the cap seals with the leaflets when the cap is closed. The closure is integrally molded in open position with raised leaflets and unfolded webs, leaflets then being lowered and the webs folded to closed position while the closure is still warm, the cap then being closed, and the closed closure then being annealed to establish the elastic positional memory of the leaflets and hinges in the closed position when product is not being dispensed through the closure.

Abstract: A multi-cavity dispensing container is provided for the co-extrusion of at least two flowable materials. The container includes a refill cartridge and a reusable base. The cartridge contains a pair of separate parallel cylinders within which are carried the flowable materials. At a lower end of each cylinder is a piston head. The lower surface of the piston head is configured as a hollow recess. The reusable base is formed with a pair of separate parallel piston support posts. These posts are characterized by a central hub surrounded with at least two outwardly projecting arms. Tops of the posts can readily engage within the recesses of the piston heads. Consequently the refill cartridge and reusable base can be readily engaged and disengaged from one another.

Abstract: A dispensing package is provided with a container and a cap. The cap includes a mechanism to fittingly engage across an open end of the container, a top portion defined by a deck, a skirt wall surrounding the deck, at least one dispensing orifice formed in the deck, a locking aperture with a wide and a narrow area preferably in a T-shape, a lid hingedly attached to the deck, a flexible post projecting downwardly from the lid, and a release mechanism along the skirt. The flexible post has an enlarged section at an end thereof which can lockingly engage underneath landings that define wide and narrow areas of the locking aperture. A flexible area along the skirt can be pushed inward against the enlarged section of the post to dislodge same from underneath the landings thereby opening the lid.

Abstract: A swab dispenser system is provided that includes a reusable outer receptacle and a replaceable refill container insertable therewithin. The outer receptacle is formed with a fin projecting vertically upwardly and centrally positioned on the bottom panel of the receptacle. The fin has a horizontal length greater than a width thereof. The refill container on its bottom wall also includes a fin. The fin of the refill container has a hollow interior for form-fittingly receiving the fin projecting upwardly from the receptacle bottom panel. Function of the fin is to allow a consumer to properly orient the refill container when placing same into the receptacle. The fin also functions to direct swabs into a proper arrangement when they are being factory filled into the container. Furthermore, the position and geometry of the fin maximizes the number of swabs fillable into the container.
