Paint tester and methods of testing paint using the paint tester. The paint tester having a sealed receptacle containing paint, a foam applicator, and a seal cutter. The methods comprising rotating the seal cutter with respect to the receptacle until one or more teeth will cut into and break a seal on the receptacle, applying inward pressure to an exterior surface of a receptacle wall causing paint to flow from the receptacle through a channel exit of the receptacle, through a conduit defined in the seal cutter, out a conduit exit encircled by crenulations, through pores in the applicator, and onto an exterior surface of the applicator, and touching the exterior surface of the applicator to a surface upon which paint is desired.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.

A tamper-evident closure (1) for a container, the closure comprising: a shell comprising a first shell part (3A) and a second shell part (3B); and a tamper-evident overcap, the overcap comprising a cap (4A) which is fixed to the exterior of the first shell part and a tamper-evident member (4B) which is releasably connected to the cap (4A) and releasably located around the exterior of at least part of the second shell part (3B), such that the first and second shell parts (3A, 3B) cannot be separated unless the member (4B) is released, and thereafter the cap (4A) is removable together with the first shell part (3A).

Disclosed is a metallic cover cap for sealing a metallic bottle, comprising a gasket provided with a flat central zone and an annular zone which includes an outer rim and an inner rim that are separated by a notch, such that the outer rim extends axially, continues circumferentially, and includes: a first surface; a second surface with a flat portion and a concave portion radially opposite the notch; and a third flat surface that extends between the first and second surfaces, and the inner rim extends axially, continues circumferentially and spaced radially inwards of the first rim, and includes: a first flat surface opposite and perpendicular to the flat zone; a second concave surface radially opposite the notch; and a third flat surface between the first and second surfaces that is inclined toward the notch.

A capsule for covering the top of a bottle includes a lower portion configured to wrap about a neck of the bottle, an upper portion connected to the lower portion and configured to be removed from the lower portion to expose a top of the neck, and a trench formed about a periphery of an upper edge of the lower portion. An assembly used to form the trench in the capsule includes a housing, and a blade extending outwardly from the housing.

An end cap which is prepared for being fastened, especially attached, to an especially pipe socket-type connecting port of a cartridge-shaped receptacle and in a mounted state serves for sealing the connecting port, including a top surface portion, a shell surface portion being connected, especially perpendicularly and cylindrically, to the top surface portion, and a flange portion connected to the shell surface portion, the flange portion including and/or forming a sealing portion, by which the end cap can be fixed and sealed to the cartridge-shaped receptacle, and a predetermined breaking/tearing portion, at which the end cap tears and/or breaks in a predefined manner when the end cap is removed from the cartridge-shaped receptacle.

A bottle-shaped can includes a cap having an excellent sealing ability but easy to be opened. A top section includes a leading end section as an upper end of a neck portion, a diametrically-largest section formed beneath the leading end section, a diametrically-shrunk section extending downwardly from the diametrically-largest section, and an outer circumferential wall section extending downwardly from the diametrically-shrunk section. The leading end section, the diametrically-largest section, and diametrically-shrunk section form a smooth curved surface. A curvature of the diametrically-largest section in a cross-section is zero or negative value, given that a curvature of the diametrically-shrunk section is positive value. A flexion section is formed between the diametrically-shrunk section and the outer circumferential wall section. The outer diameter of the outer circumferential wall section in which the curvature is zero or negative value is larger than an outer diameter of the flexion section.

A biodegradable container including a unitary polymeric body element having a top portion and a cylindrical body portion. The top portion has a cylindrical neck wherein the cylindrical neck defines an inner surface and an outer surface. The container further includes a polymeric bottom element welded to the cylindrical body portion of the unitary polymeric body element. A polymeric cap defines an internal rim configured to be received by the inner surface of the cylindrical neck. The polymeric cap includes an external cover having an interior surface which may be tapered so that the outer surface of the cylindrical neck and the interior surface of the external cover form an inner seal. The interior surface of the external cover may also form an outer seal with the outer surface of the cylindrical neck when the polymeric cap is in a closed position.

A container closure and methods are disclosed for providing visible evidence of removal of the closure from a container after installation by a manufacturer. The closure includes tamper evidence bridges comprising small tabs of material that extend from a bottom-most edge of the closure to a tamper evidence ledge of the container. The bridges break when the closure is rotated relative to the tamper evidence ledge, thereby providing readily visible evidence that the closure has been removed after installation by the manufacturer. In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.
