Abstract: A bottle assembly is provided including a bottle having an end portion with a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided including a base member and a sealing member. The sealing member is movable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.

Abstract: An aspect of the invention provides a container closure for a container comprising a body portion having a first end configured for attachment to a container and a second end configured to allow content of the container to exit the container closure, a reservoir positioned within the body portion between the first and second ends thereof and an actuable seal that is moveable between a first configuration in which the reservoir is sealed and a second configuration in which the actuable seal is moved in the direction of the second end of the body portion to create a gap between the actuable seal and second end of the body portion, wherein the actuable seal is moveable between the first configuration and second configuration by a plunger extending from the first end of the body portion to the second end of the body portion and wherein the actuable seal engages a surface of the reservoir when in the first configuration.

Abstract: A smoking substitute system and device comprising a heater apparatus for a heat not burn smoking substitute device, the heater apparatus comprising a solid blade-type heating element adapted for insertion into a consumable for the heat not burn smoking device, wherein the heating element has a multi-sectional cross section comprising at least two sections, each of the sections having a surface normal vector with a direction; and wherein the directions of the surface normal vectors are non-parallel.

Abstract: According to a first embodiment, the valve assembly comprises a first arm having a first valve portion and a second arm having a second valve portion. The valve assembly is foldable from an unfolded state to a folded state, such that the first valve portion engages with the second valve portion. According to a second embodiment, the valve assembly comprises a liquid inlet, a liquid outlet, a conduit, a blocking member, and a flexible member arranged to seal against the blocking member. The conduit comprises at least one bend and is arranged such that fluid may flow from the liquid inlet, past the bend and through the liquid outlet to at least indirectly impinge the flexible member.
