Abstract: A novel method for containing materials in a container material adaptable to a wide variety of different materials including food products and household chemical products is described. The material utilized is intended to be a substitute for glass, plastic or metal containers, and comprises a resin hardened petroleum wax molded to form the container.

Abstract: The present invention provides a pilfer-proof resealable crown closure cap which has a top crown and a skirt depending from the top crown, the skirt having a pair of diametrically opposed slots therein, each slot extending substantially the full height of the skirt. Preferably, each of the slots has a generally inverted U-shaped configuration and the skirt is provided with rounded corners at the free marginal edges of the skirt and slots.

Abstract: A lever-actuated closure for bottles or the like containers is described which closure comprises a closing member sealingly mountable on an outlet orifice of the container, an actuating member having a manually operated gripper part and being hingedly mounted below the outlet orifice, and a connecting member hingedly attached to the actuating member and to the closing member at the outside thereof, which closure can be transferred, by means of the actuating member, from an open position, in which the closing member frees the outlet orifice, through elastic deformation of at least one of the parts of the closure via a dead-center position, in which the hinge axis of the actuating member and the two hinge axes of the connecting member are in a common plane, into a closed position, in which the closing member seals the outlet orifice, or vice versa from this closed position into the open position, the gripper part of the actuating member being, in the closed position, above the elastically deformed closing membe

Abstract: A plastic material closure member for a container, said closure member having a gripping portion and a substantially cylindrical sealing portion adjacent thereto, in which the sealing portion comprises a sealing wall and a centering member adjacent thereto, and in which the walls of the gripping portion, the centering member and the sealing wall are laterally deformable.

Abstract: A tamper-indicating closure combination consisting of a container having a circular neck and a twist-on cap therefor. The container neck has external interrupted thread sections with ratchet teeth on their under surfaces. The cap has similar, cooperating internal thread sections on the inner surface of its skirt with ratchet teeth on their upper surfaces. When the cap is turned onto the neck, the sets of ratchet teeth interengage and lock the cap against retrograde rotation. The cap also has a puller which is connected to the cap, a first section thereof being connected by frangible portions and a second section thereof being connected permanently to said cap. In order to remove the cap, the puller is broken away at the first section and then is pulled upwardly and outwardly relative to the container neck to disengage the cooperating sets of ratchet teeth. The cap is replaced by turning it onto the bottle neck for re-engaging the cooperating threads and ratchet teeth.

Abstract: A so-called child-resistant closure for a container containing a substance which may be injurious to the person, especially to a child of tender years, e.g. poisonous household items such as rat poison. The closure is desirably molded in one piece and comprises two principal parts, one part adapted to be engaged and disengaged with a pouring neck of the container, e.g. a screw threaded connection, to obturate the opening thereof and another part surrounding the first and angularly and/or translationally displaceable relative thereto. Each of the parts is respectively provided with cams and cam followers so arranged that when the outer or surrounding part is angularly displaced with respect to the inner or surrounded part, as by grasping and turning, and/or shifting linearly, the cams and followers are engaged to exert inward radial force to supplement normal grip of the closure on the container neck.

Abstract: A closure system for a medical liquid container having a dispensing outlet surrounded by a flange over which is fitted a plastic cap. The cap is externally threaded and has an outwardly-projecting brim at its lower end overlying the flange. The brim is sealed to the flange along an annular zone having an inner boundary defining an annular line of weakness, and an internally-threaded breakaway ring is threadedly disposed on the cap. The breakaway ring includes a plurality of circumferentially-spaced depending projections for stressing the brim along portions of the annular line of weakness and for initiating and propagating the rupture of the brim as the breakaway ring is screwed downwardly upon the cap.

Abstract: A closure of injection-moulded synthetic plastic material for a bottle or other receptacle, such closure comprising a tubular body having a throat insertable into the neck of the bottle and an integral fluid-tight diaphragm across the throat with an external gripping device by which the diaphragm can be torn off, wherein the gripping device is a ring separate from the watertight diaphragm but joined to the rim of the latter by means of a base connection which is also integrally moulded. The closure has an integrally moulded pouring spout, and a replaceable cap protecting the spout.
