A screw cap for sealing containers with threaded necks includes an outer body, having a cylindrical outer wall closed at one end by a circular lid and an interior neck seal adjacent to the circular lid. A female thread extends around an inner surface of the cylindrical outer wall. The female thread has a main portion having substantially uniform thickness, and an attachment portion having a thickness which is less than the thickness of the main portion. The female thread is attached to the inner surface of the cylindrical outer wall in the region of the attachment portion, and the attachment portion is configured to permit deflection of the female thread.

A seal and method of forming a seal for a resealable container includes a removable cap that is selectively received over a pour opening formed in a can body. A seal is adhered to the end wall of the cap and includes a continuous, first axial region extending outwardly from the inner surface of the cap. The seal first region is dimensioned for engagement with the opening in the container and sealing the container along an inner diameter thereof. Reduced on-torque/off-torque are required since the seal is formed on the inner diameter, and a down force is substantially reduced to assemble the cap to the container.

A screw cap container including a container main body and a screw cap. The container main body includes a mouth tubular portion, which is provided with slope screw portions. The slope screw portions include: upper screw protrusions disposed at three or more different positions; lower long screw protrusions having left end positions same as left end positions of the upper screw protrusions, and each having a length longer than a length of each upper screw protrusion; and oblique screw protrusions extending obliquely from right ends of the lower long screw protrusions and each being connected to a left end of a different one of the upper screw protrusions. The screw cap includes a top wall and an outer circumferential wall. The outer circumferential wall is provided with cap screw protrusions disposed in the same number as the number of the upper screw protrusions.

A container closure system for sealing a bag when the bag has been opening includes a bag that has a top end. The top end is open. A funnel is provided and the bag is selectively inserted through the funnel. A cap is removably coupled to the funnel such that the cap closes the bag.

A high quality child resistant container comprising a durable metallic reservoir and durable plastic metal cap. The child resistant container comprises a durable and rugged reservoir and similarly durable locking cap. The cap is secured to the reservoir by a threaded, or bayonet-style connection. Once installed on the reservoir, the cap is prevented from being easily removed by a child, due to child resistant features integrated in the design of the cap and reservoir. Also, a method of reducing friction between the sealing surfaces of a sealed container. Specifically between the reservoir, cap and seal of a container, which allows easier closing of containers which require a simultaneous compression and twist motion to close.

A container assembly including a container and a metallic closure. The container includes a polymeric body and a polymeric finish. The polymeric finish includes a plurality of threads. A lug lock is associated with each one of the plurality of threads. The metallic closure includes at least three metallic lugs configured to cooperate with the plurality of threads to couple the metallic closure to the polymeric finish.

A screw cap is aligned using a loading piston by a method for aligning the screw cap and the loading piston in relation to each other, and after alignment a method for screwing a screw cap onto a threaded neck portion of a packaging container is performed. The screw cap includes a base portion having a top and a bottom surface, and an annular portion raised from the base portion, the annular portion having an inner surface and an outer surface; and at least one first threaded portion arranged on the inner surface of the annular portion. The base portion includes engagement features, such that the screw cap is configured to engage a tool with at least one complementary engagement feature in a process of screwing the cap onto the container with the complementary threaded neck portion.

A device for detecting an analyte in a sample is provided, which comprises: a collecting chamber containing an opening for collecting a liquid sample; a detecting element for detecting an analyte in the liquid sample; and a lid for covering the opening of the collecting chamber. The device further comprises an indicating device thereon to indicate whether or not the lid covers at an appointed position. The operation of the device is very simple.

A container assembly including a container and a metallic closure. The container includes a polymeric body and a polymeric finish. The polymeric finish includes a plurality of threads. A lug lock is associated with each one of the plurality of threads. The metallic closure includes at least three metallic lugs configured to cooperate with the plurality of threads to couple the metallic closure to the polymeric finish.

A stackable container, including a body and a cap threadingly engageable with a neck portion of the body and having a vaulted interior and a top portion formed with a frustrum-shaped depression for snap-registered engagement with a base portion of a counterpart of the body, the cap further including handle projections and a skirt. Opposite stop structures prevent rotation of the cap relative to the body beyond predetermined threaded engagement; a detent releasably captures the body in the predetermined threaded engagement. A base portion of the body having inclined side walls facilitates rotation of the body with respect to the cap. The skirt guides the body into alignment with the cap. The base can have four of the side walls forming a square, the containers of a stack having any of four relative orientations. A consumable product such as a cosmetic can extend into the cap from the body.
