A cap apparatus includes a cap body and a valve body. The valve body includes an upper portion, a lower portion, and a stem intermediately disposed between the upper portion and the lower portion, the valve body including a bore formed therein having concentric alignment to and traversing the upper portion and the stem, and the valve body including a perforation formed therein having concentric alignment to and traversing the stem and the lower portion. The perforation forms a substantially impermeable seal within the valve body. The cap body includes an aperture in coaxial alignment with the bore and the perforation. The inner surface of the cap body includes multiple internal threads.

A sealed container, comprising a container and a container cover. The container cover comprises a cover body; the lower side of the cover body is provided with a movable base; elastic sealing members are provided between the movable base and the cover body; the elastic sealing members are connected to the cover body or the movable base; when the movable base is moved upward, the outer edges of the elastic sealing members are deformed outward, so that the elastic sealing members form sealing portions between the movable base and the container, to seal the container cover and the container; the upper side of the container cover is provided with an opening and closing mechanism; the opening and closing mechanism comprises a rotary switch and a sliding cover.

An air-tight storage container system has a container having an open top and a container closure unit configured to be placed over the top. The closure unit has a series of stacked, interlocking components, including a handle member, a flexible deformable gasket member, a snap inner piece, and a bottom member. When these closure unit components are interconnected and the closure unit itself is positioned atop the container, the closure unit is pushed and rotated, held within the container to establish an air-tight seal within the container.

A self-sealing container, used for transferring one or more air sensitive samples between vacuum systems, includes a housing with a cavity that holds the sample(s), and a lid disposed on top of the housing. The lid is configured to interface with the housing to form a seal over the cavity when the lid is closed. At least two flexure systems, each coupled to the housing and the lid, are disposed on opposing sides of the housing. The flexure systems apply forces to the lid that move the lid horizontally and vertically above the housing, into an open position. A pneumatic actuator, movably coupled to the housing and the lid, that is actuated by a change in ambient pressure. When actuated, it applies forces that move the lid horizontally and vertically to the closed position, in opposition to and in excess of the forces applied by the flexure systems.

Aspects of the present invention disclose and describe embodiment containers for displaying, visualizing, and aroma sampling botanical materialssuch as tea, cannabis, and the like including a container body, lid, and lenswhich may have various shapes. In a preferred embodiment, the lid is shaped to define a recessed area with scent openings permitting aroma sampling of a sample contained within. A removable plug is shaped to fit within the recessed area of the lid. The container body and lid, with the removable plug fit within the lid, and form an airtight chamber within. A botanical sample may be visualized through the lens.

Pressure relief blow out plugs for a container are disclosed as well as methods of using the same. One disclosed method involves providing a glass container that comprises a base and a body extending away from the base. The base includes a wall that defines a pressure relief passage. The method also involves inserting a pressure relief blow out into the pressure relief passage to seal the passage. The plug comprises a first inboard flange extending radially outwardly from the plug body, a stem, and a second inboard flange extending radially outwardly from the plug body and being spaced apart from the first inboard flange by a stem. The first inboard flange includes a first outboard sealing surface that provides an axial seal against the wall of the base of the glass container, and the second inboard flange including a circumferentially interrupted outboard facing retention portion the defines vent gaps.

A re-closable vent for a container closure which requires no pre-formed holes in the closure deck, provides a tamper-evident feature, and provides simple rotation of a cap structure to open and a vent after punching out a frangible deck section.

A cap, a method of using a cap, and a system for using the cap. The cap is capable of being fitted to a bottle. The cap includes a transfer port; and a vent port. The vent port includes a membrane and a valve.

A display container for botanical samples includes: (a) an enclosure including a container body having an open top and a lid detachably mounted to the container body and covering the open top. The container body and the lid enclose an interior chamber for storing a botanical sample. The lid has a transparent viewing section extending over the interior chamber for viewing the botanical sample. The display container further includes (b) one or more scent ports extending through the lid between the chamber and environment. The one or more scent ports are spaced apart from the transparent viewing section. The display container further includes (c) a plug mounted to the lid and sealing the one or more scent ports. At least a portion of the plug is movable away from the lid to expose the one or more scent ports for sampling an aroma of the botanical sample.

A container lid having a panel with an opening for emptying a container, where formed on two opposite walls of the said opening are guides declining towards the bottom surface of the panel, and further having a slide piece with catches formed on the top surface of the slide piece declining towards the top surface of the slide piece, said slide piece further featuring a pull tab, where the said catches are fitted slidingly in the said guides, where the pull tab is formed on the top surface of the slide piece, and where a recess to accommodate the slide piece is formed on the bottom surface of the panel around the opening for emptying the container.
