A closure device for a container having a container opening has a lid element for closing the container opening, a chamber associated with the lid element, and an inner housing. The chamber and the inner housing also have closure and opening devices corresponding to one another and which interact with one another so that a fluid housed in the chamber can exit into the container due to a movement of the lid element relative to the inner housing. The chamber has a free-projecting closure edge annularly surrounding a central axis of the chamber which, when in use, is positioned in the inner part of the container, and which interacts with the inner housing in the closed state. The inner housing forms a chamber base delimited by the closure edge. The chamber base is formed such that it slopes towards a free end of the closure edge.

Some embodiments are directed to a bodily fluid sample collection device for the collection of naturally expressed bodily fluids and include a cap engageable with a tube to close a mouth of the tube. The cap includes a chamber for containing a reagent. The tube defines at least partly a sample collection space for receiving the naturally expressed bodily fluid. The cap comprises first and second cap portions relatively movable with respect to each other. The first and second cap portions are configured such that, responsive to engagement of the cap on the tube, one of the cap portions is caused to move integrally relative to the other cap portion to open the chamber and permit fluid communication between the chamber and the sample collection space. The reagent in the chamber is thereby permitted to mix with the bodily fluid in the sample collection space. A method of organizing and processing samples is also described.

A modular flow monitoring package (MFMP) is provided for use in an additive delivery system. The MFMP may be manufactured as an add-on to be added to an existing additive delivery system, or may be incorporated into a cartridge or container structure. The MFMP includes a flow sensor for sensing flow of a base fluid and user actuator position sensors for sensing the position of one or more user actuated additive flow adjustment levers. A visual display, which may comprise an array of multi-color LED's may convey information to a user that is relevant to a user's use of the additive delivery system or the user's nutritional needs. Such information may include a current dosage of additive, being delivered, whether a recommended dosage of additive has been consumed, remaining life of a cartridge or supply of additive, and other data relative to health or performance monitoring.

An attachment for a beverage container may comprise a cap configured to attach to an opening in the beverage container. The cap comprises an opening. The attachment also comprises a tube passing through the cap. The opening in the cap is located proximate to a first end of the tube and a second end of the tube is configured to be located within the beverage container when the cap is attached to the beverage container, such that a beverage contained in the beverage container can flow through the tube and out of the opening in the cap. The attachment also comprises a container attached to the tube and configured to hold a liquid. The container comprises an opening to allow the liquid to flow from the container into the tube and out of the opening in the cap. The attachment also comprises a restrictor between the opening of the container and the tube to control and/or restrict the flow of the liquid from the container into the tube. The restrictor and the tube are configured such that the liquid begins to exit the opening in the cap before the beverage begins to exit the opening in the cap.

The present disclosure belongs to technical field of a powder-water mixing container, in particular to a powder-water integrated bottle. The powder-water integrated bottle comprises bottle body, convenient opening-closing toggle device for separating powder from water, bottle nozzle and bottle cap, wherein bottle body is movably connected with the bottom of the convenient opening-closing toggle device, the top end of convenient opening-closing toggle device is fixedly connected with bottle nozzle, the end's of bottle nozzle is rotatably connected with bottle cap, inner side of bottle cap is clamped with outer side of top end of bottle nozzle. The powder-water integrated bottle according to present disclosure is durable, capable of being used many times, avoiding large amount of waste, preventing unnecessary garbage from polluting environment, conveniently opening a powder-water mixing switch component in labor-saving manner through shifting block provided, suitable for the frail people like the elderly and children.

A closure device (210) for use on the neck (238) of a bottle comprises a cap member (236) having a side wall (237) adapted to be secured to the neck, a fluid chamber (260) fixed at its upper end to the cap member and having a bottom aperture (266) at its lower end, a housing (254) at least partially surrounding the fluid chamber and having a flange member (258) adapted to extend at least partially across the top of the container neck, and a plug member (264) fixed to the housing and sealingly engageable in the bottom aperture of the fluid chamber. The plug member (264) has a nozzle (274) therein, and the housing (254) is adapted to move relative to the cap member (236) between a first closed position of the closure device before securing to the neck of the bottle, in which the plug member (264) seals the bottom aperture (266) closed and the housing or cap member is engaged by a detent member (204) provided to prevent movement of the housing away from the cap member, and a second armed position in which the closure device is secured to the neck of the bottle, and in which the plug member (264) continues to seal the bottom aperture (266) closed and the flange member (258) or detent member (204) is deformed to a position in which the housing can no longer be engaged by the detent member (204). An internal rib (206) on the housing may engage with the detent member to prevent movement of the housing away from the cap member in the first closed position of the closure device. The detent member (204) may be deformable such that in the second armed position of the closure device the detent member is deformed to a position in which the internal rib can no longer be engaged by the detent member, to permit the closure device to move to a third firing position when the closure device is removed from the neck.

A cartridge pump according to the present invention includes: a housing unit connected to a container; a head unit rotatably provided in the housing unit; a storage unit provided in the head unit and having a storage space in which contents are stored; and a mixing operator configured to lead the contents in the storage unit into the container in cooperation with an operation of the head unit.

A cover for a medicine container is provided. The cover contains a deactivating material within it which can, upon release into a medicine container, deactivate and/or destroy a medicine within the container. The cover may have an automated release mechanism which controls release of the deactivating material into the medicine container.

An adjustable additive cartridge that provides adjustable metering of additive to a base fluid as the base fluid is flowing through the cartridge. A spout is mounted for limited rotation within a base element of the cartridge. Rotation of the spout results in varying degrees of flow of additive into a base fluid flow path through the cartridge. The cartridge may be used with a portable beverage container, such as a sports bottle or off-the-shelf water bottle. The supply of base fluid in a container used with the cartridge may be kept in an unmixed, pure state, and other cartridges, each having different additives (i.e., flavors) may be used interchangeably with the same base fluid supply. The cartridge allows a consumer/user to experience different additives, such as different flavors or supplement compositions, for a given supply of base liquid in a single container. A check valve on the cartridge prevents backflow of the base fluid. An integrated filter for filtering base fluid flowing into the cartridge may be provided. The additive cartridge may be sealed to provide for extended storage and to provide a user/consumer with evidence of integrity, quality and/or tampering prior to purchase and/or use. Visual and tactile indicators of the amount of additive being added to a base fluid may be provided. A container may retain a spare additive adjustable cartridge on the container.
