A container closure. The closure comprises a pressure closure assembly and an outer release shell configured to be coupled thereto. The assembly comprises a relief valve and an inner shell having a base wall, a pressure relief slot, and an outer skirt extending away from the base wall and including first and second portions. The release shell includes a first portion having a base wall configured to overlap a portion of the inner shell base wall, and a tab corresponding to the slot of the inner shell. The first portion further includes an outer skirt extending away from the first portion base wall and configured to wrap around the first portion of the outer skirt. The release shell further includes a second portion having a base wall configured to overlap a portion of the inner shell base wall, and an outer skirt extending away from the second portion base wall.

A receptacle forming a chamber partially filled with an active substance, wherein the receptacle is a body and a cap which closes the body. The cap includes a top wall with a first main side facing an interior of the chamber and a skirt formed with the first main side of the top wall. The body includes a bottom wall and a sidewall. The skirt and the sidewall surround one another in contact with each other. The walls surrounding the chamber include the bottom wall, the top wall and either the skirt or the sidewall. At least one ventilation path is provided between the skirt and the sidewall, such that the ventilation path connects the chamber with the outside atmosphere.

An example lid assembly can include a lid and a slider. The lid can include a wall defining a recess. The slider can be configured to slide in the recess and can be configured to move between a closed position where the slider covers the opening to aid in preventing spilling of contents of the container, and an opened position where the slider uncovers the opening such that the contents may be poured from the container. The slider can be configured to be removable from the lid and can be replaced back on the lid. Additionally, the slider can be formed from upper and lower sled elements that are magnetically coupled to one another.

A removable container for powder or liquid includes a housing, a spilling mechanism and a bypass element. The housing hangs within a bottle and is capable of storing powder within the bottle while being sealed from a precursor liquid held within the bottle. The spilling mechanism enables the powder to spill out of the housing and into the precursor liquid and the bypass element provides the precursor liquid out of the bottle without mixing with the stored powder.
