The present invention provides a personal vaporizer apparatus having a holding cartridge for storing a pressurized mixture. The holding cartridge contains a bottom end and an outlet end. The bottom end may contain a refill valve. The outlet end gets threaded unto a pressure regulating mechanism having a first valve. The pressurized mixture exits through the valve into a discharge channel, where the mixture exits through the mouthpiece in form of vapor. The holding cartridge may be replaced, with the rest of the device remaining intact. The pressurized mixture may be introduced into the external contain directly. The entire operation of the personal vaporizer apparatus is mechanical requiring no electronic power source to fuel operation.

A perforable container cap having a top surface that includes a central aperture covered by a membrane that is thin, relative to the thickness of the rest of the cap structure, and, therefore, relatively easy to pierce or puncture with a sampling tube or needle. Embodiments of the container cap may include a membrane comprising a thin plastic, rubber or foil.

A chemical reservoir assembly may include a reservoir containing a liquid chemical and a closure sealing off an outlet opening of the reservoir. The closure can include a top wall having an access opening and a sealing disc positioned under the top wall and across the access opening. The sealing disc may include a vent opening positioned under the top wall and offset from the access opening. The sealing disc can be fixedly positioned relative to the top wall and include a compressible material configured to compress in response to a discharge device being inserted into the access opening and pressing against the compressible material. In response to the force of the discharge device, the compressible material can compress to open a venting pathway from the access opening through the at least one vent opening.

A souvenir apparatus is provided for capturing and retaining air from a particular location. The apparatus includes a vessel containing a vacuum and an activating arrangement configured to allow air to be sucked into the vessel from the location where the device is activated. The activating arrangement can be provided with audible and/or visible indicators to show that the apparatus has been activated. A cover can optionally be affixed to the top of the apparatus as a decorative feature and/or to provide an air-tight seal after activation. Adhesive labels and/or writeable surfaces can be provided on the apparatus to indicate the location, date, and/or other information pertaining to where/when the apparatus was activated.
