A gas absorption box includes a box body, at least one gas absorption member and an outer housing assembly, the box body has an accommodating cavity; the gas absorption member is elastic and is provided with a first inner cavity, and the first inner cavity is in communication with the outside of the box body; and the outer housing assembly is arranged in the accommodating cavity and is elastically connected to the box body, and the outer housing assembly has a second inner cavity for accommodating a gas absorbent, the second inner cavity being in communication with the first inner cavity, and the gas absorption member being capable of absorbing gas for the second inner cavity. When battery powder or some positive-electrode materials for batteries are transported, hydrogen generated by the battery powder or some positive-electrode materials for batteries gathers towards the upper portion of a ton bag.

There are provided a check valve structure that not only prevents backflow of fluid but does not discharge fluid for unintended pressure in a correct direction, and a squeeze container using the check valve structure. A squeeze container includes a container and a nozzle member attached to an opening of the container. The nozzle member is provided with a check valve structure that is closed in an unloaded state, and that blocks a flow of fluid from downstream and allows a flow of fluid from upstream. The check valve structure is opened when an elastic valve element elastically deforms in two stages due to pressure of fluid from upstream (container).

A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. First an outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform, and the preforms connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET. To prevent mutual bonding during molding of the second, a non-stick coating can be sprayed on a surface portion of the first preform prior to molding, the second. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded.

The present invention relates to a closure for bottles with means for evidencing a first use when it is in nominal conditions, i.e., fitted on the mouth of the bottle. The closure contains at least one spout (5), a plug (6) of the spout and a cap (3). The present invention allows evidencing the first opening of the closure due to the internal configuration of the closure changing. This change modifies the internal configuration and allows one or more visual changes in the device. The change in the internal configuration is based on modifying the position of an annular band (7) arranged between the plug and cap.

An aerosol valve with a refill prevention mechanism is provided. The valve has a valve stem disposed in a valve housing that defines an inner chamber. The valve stem has upper passage in an upper portion of the valve stem that is provided with a flexible resilient member. The flexible resilient member is compressed on an orifice or aperture communicating with the housing to create a seal and prevent filling in an open position when pressure in the upper passage is greater than a pressure in the inner chamber. The flexible resilient member is deflected away from the orifice or the aperture when pressure in the upper passage is less than a pressure in the inner chamber to allow dispensing of a product.

An element for an aerosol-generating system, a cartridge for an aerosol-generating system, and an aerosol-generating system, wherein the element, the cartridge and the aerosol-generating system each include a storage portion for storing an aerosol-forming substrate and a manually operated disabling mechanism for rendering the element, the cartridge, or the aerosol-generating system irreversibly inoperable. The element, the cartridge, and the aerosol-generating system may include an aerosol generator and one or more air passages. The disabling mechanism may be configured to render at least one of the storage portion, the aerosol generator, and the one or more air passages irreversibly inoperable.
