A pouring spout sealing structure of an inside plug includes a sealing member including a bottom part for sealing an opening of a pouring spout of the inside plug, a peripheral wall rising from the peripheral edge of the bottom part, and a knob part extending from the peripheral wall, in which the sealing member is connected to the upper end of the opening of the pouring spout at the peripheral edge of the bottom part, the connected portion constitutes a thin part breakable by a certain pulling force, and the peripheral wall is inclined upwardly and outwardly from the opening of the pouring spout. The container pouring spout sealing structure achieves both sealability and easy opening properties, reduces number of parts and manufacturing steps, and is applicable to small containers such as cosmetic containers.

An oil tank cap adapted to be removably engaged with an oil tank having an oil storing space. The oil tank cap includes a cap body, an air seal, and an air valve. The cap body includes an outer casing, and a cap base being plastic and one-piece, and defining an accommodation space with the outer casing. The cap base has an annular seat portion that has at least one exhaust hole, a tube portion, a separation portion having at least one ventilation hole. The air seal has a protrusion portion, and an annular body that encircles the ventilation holes. The air valve is inserted into the tube portion, is connected airtightly to the air seal, and is operable to open or close for balancing pressure of the oil storing space and pressure of an external environment.

An oil tank cap is adapted to be removably engaged with an oil inlet of an oil tank. The oil tank cap includes a cap body that is one-piece, that is plastic, and that includes a cap portion adapted to be disposed outside the oil inlet, and a plug portion extending from the cap portion along a central axis of the cap body and adapted to extend into the oil inlet. The plug portion has a surrounding surface that surrounds the central axis of the cap body, a base surface, an accommodating slot extending through the surrounding surface, and at least one recess formed in the base surface, extending towards the cap portion, and being isolated from the accommodating slot. The oil tank cap further includes a spring strip that has a positioning portion disposed in the accommodating slot, and two abutting portions extending outwardly of the accommodating slot.

A closure cap for liquid containers, in particular for medicine bottles, includes a cover section, a screw collar arranged thereon with an internal thread for screwing onto an external thread of the liquid container, a functional insert, in particular a dropper or dosing insert, which can be detachably fixed in the closure cap by means of a base section for assembly purposes, and a snap connection between the closure cap and the functional insert, which snap connection is formed by an inwardly projecting bulge projection which runs at least in sections around the inner wall of the closure cap and a latching web which is arranged on the functional insert, is resilient in the radial direction, runs at least in sections around the base section and engages behind the bulge projection in an intermediate assembly position.

The description relates to device retention assemblies. One example can include a bucket having an open end and defining a volume that contains electronic components. The example can also include a lid positioned over the open end of the bucket. A retention assembly can be configured to bias the lid against the bucket to seal the open end. The retention assembly can include a tab that is secured to the lid with a fastener that extends through the retention assembly into the lid without extending completely through the lid and does not contact the bucket.

The embodiments of the present disclosure provide a stopper comprising a plug and a pierceable membrane, the plug including a cavity between a pierceable membrane and a lower opening. The pierceable membrane and the cavity can form a tortuous path that reduces interactions between the contents of the container and the ambient environment. The cavity can be bounded by a plastic insert disposed within the plug. The plastic insert can include insert walls, the lower opening, and an insert flange. The pierceable membrane can be bonded to an upper surface of the insert flange.

A closure assembly for filling a container under isolated conditions. The closure assembly includes a collar with internal threads for coupling with a finish of the container. A disc includes first coupling members for removably coupling with the collar. A liner is secured to the disc. The liner is seated on the finish of the container when the collar is coupled to the finish.

A closure system for refillable containers includes a closure ring with a central opening and an annular skirt with a tab, a flange adjacent to the central opening and an annular recess between the flange and a wall of the closure ring; a sealing member having a central portion with a diameter larger than the central opening and an annular flange, the flange fitting within the annular recess, an upper portion fitting within the central opening; a container neck with external screw threads that engage the internal screw threads, a locking ring with a notch defined by at least one ramp adjacent to the notch, the notch configured to accept and hold the tab as the closure ring is screwed onto the container neck; the sealing member compressed between the closure ring and the container neck when the closure ring is screwed onto the container neck.

A sealing cover for covering an opening of a barrel body includes an outer cover body, an inner cover body, an airtight ring and an operating member. The outer cover body includes two pivot connecting portions. The airtight ring is sleeved on an outer peripheral surface of the inner cover body. The operating member is pivotally connected to the pivot connecting portions and the inner cover body. The operating member is operable to pivot so as to drive movement of the inner cover body between a sealed position and an unsealed position. When at the sealed position, the airtight ring is deformed and airtightly pressed between the barrel body and the outer cover body. When at the unsealed position, the airtight ring restores to its original shape and is configured not to be pressed between the barrel body and the outer cover body.

A painting supplies storage device that prevents drying and settling of paint includes a container, which has an open top for addition of an open can of paint. A lid is selectively attachable to the container to sealably close the open top. A hole is axially positioned in the lid. A first rod is positioned through the hole and is rotationally and sealably attached to the lid. A lower end of the first rod is positioned proximate to a bottom of the container and its upper end protrudes from the lid. A plurality of paddles is attached to and extends from the first rod. A rotator assembly is attached to the upper end of the first rod to selectively rotate the first rod, whereby the paddles mix the paint. A shell, an upper facet of which is open, is attached to the container for stowage of one or more painting tools.
