The containment system includes a lid having a gasket and a first threaded connection, one or more insertable receptacles having a flange which includes nesting geometry, and a jar having a second threaded connection, wherein the lid and the jar connect via the first threaded connection and the second threaded connection. In some configurations, the flange(s) of the insertable receptacle(s) are disposable between the gasket and a top lip of the jar when the lid and the jar are connected.

The invention relates to a glass vessel having at least one wall and manufactured from a base material which is an alkali-containing silicate glass. It is a feature of the glass vessel that at least a surface layer is enriched in potassium and depleted of sodium and/or lithium, while an inner layer, especially one directly adjoining the surface layer, is not enriched in potassium and not depleted of sodium and/or lithium, and that the glass vessel has compressive stress up to a compressive stress depth and tensile stress beyond the compressive stress depth, wherein the tensile stress rises with increasing depth up to a tensile stress maximum within the inner layer and/or wherein the progression of the tensile stress as a function of depth does not have a linear section and/or wherein the progression of the tensile stress as a function of depth does not have a section in which tensile stress is constant.

An airtight container including a container body having a neck with an opening at one end, a cap having inside a portion having a convex lower end side and attaches to the neck, and a packing. A vertical cross-section of a mouth of the opening forms an upwardly convex curve. The packing has a first concave portion formed on the outer rim of the upper surface, a second concave portion formed on the lower surface sharing a bottom with the first concave portion, and a bent portion radially outboard of the center of the packing and radially inboard of the first and second concave portions are formed, to generate stress that widens the first concave portion and narrows the second concave portion when the cap is attached and the inner surface of the second concave portion is contacted against the mouth of the opening of the neck.

A storage unit is for storing products that can be affected by humidity, particularly tea. An outer container has a closed outer wall, an upper side on which the outer container is open and has an upper edge, and a lower side on which a closed bottom is arranged. An inner container has an inner space for receiving the product that can be affected by humidity, a wall surface provided with a number of air-exchange openings, a filling opening, a sealing edge defining the filling opening, and a closed bottom. The inner container is reversibly placed in the outer container, the filling opening of the inner container being upwardly oriented towards the upper side of the outer container.

A self-standing packaging container capable of achieving both strength and disposability even if the container has a wide mouth is provided. A container according to the present invention includes: a container body that has an opening part at an upper end of a tubular member; an annular member that is bonded to the upper end of the tubular member; and a lid member that seals the opening part to be openable and closable. The container body has a bottom surface member that is bonded to the tubular member at a bottom surface part of the tubular member. The tubular member is constituted by a flexible laminated body of three or more layers including a barrier layer and a resin layer. The lid member is coupled to the annular member by any of a hinge, fitting, and a screw to be openable and closable.
