The present invention relates to a tumbler for enabling an additive stored in a storage space to be added, in a fixed amount, to drinking water by a pumping means such that a user can drink the drinking water, and the present invention comprises: a drinking water tray of which an upper part is opened, and a lower end is shielded so as to form, on the inner side thereof, a storage space for storing drinking water or a beverage; an additive storage tray of which an upper part is opened, and a lower end is shielded so as to form a storage space in which an additive, to be drunk by being added to water, is stored.

A universal closure valve adapter attachable to a neck wall of a first container that forms a periphery of an opening having a diameter. The universal closure valve adapter includes a closure valve assembly that is attachable to a closure valve assembly of a second container. A flange transversely extending from the closure valve assembly of the first container. The flange includes a plurality of tank neck engagement assemblies. Each of the plurality of tank neck engagement assemblies are spaced apart from each other about the flange.

Devices and methods for removing oxidizable stains are provided. In one example, a device includes a device body having an opening and an internal space disposed therein. The device body includes a wall that at least partially surrounds the internal space. At least part of the wall is a flexible wall. A frangible wall separates the internal space into a first chamber and a second chamber. One or more solid components are disposed in the first chamber and include an active oxygen component. Water is disposed in the second chamber. A bleach activator component forms part of the one or more solid components or is included with water. The device is configured such that when a force is applied to strain the flexible wall, the frangible wall breaks to allow contact between water and the one or more solid components to form a peracid solution.

A concentrate container that is coupled to a drinking container having an output for discharging a drink is proposed. The concentrate container has a chamber in which a concentrate is kept, an outlet through which a concentrate is put into the drinking container, and a container mouth for discharging a liquid mixture of the concentrate and a drink to the outside when the drinking container and the concentrate container are combined. The inner diameter of the concentrate container outlet is determined to be fitted on the drinking container outlet, a thread is formed inside the concentrate container outlet, and the thread is engaged with a thread of the drinking container outlet.

Device including a bottle having two open ends and a central body receiving a first product, one end of the bottle has an orifice receiving a stopper which contains a second product to be mixed with the first, another end of the bottle has an orifice receiving a removable cap provided for withdrawing the mixture after removal of the cap.

The present invention provides a mixing container manufactured through injection molding, comprising: a material receiving part having an outlet, a receiving space, an open lower side, and a clamp coupling part; a bottle end which covers the open lower side of the material receiving part and has a coupling part formed inside the bottle end, a first sealing film, a sealing means, and a stop means; and a bottle end clamp which is coupled with the clamp coupling part to prevent separation of the bottle end and has a coupling part, and a bottle end separation prevention part. A mixing container can be manufactured by an assembly process alone, thereby simplifying the manufacturing process, and allowing easy disassembly of assembly of components to facilitate recycling thereof and prevent environmental pollution.

A system for connecting containers which is intended for the temporary assembly of a first and a second container, said connection system comprising a closing sleeve, provided with a first part suitable for being mounted on the first container, and said closing sleeve also being provided with a second part which is suitable for allowing the temporary mounting of the opening of the second container and a membrane separating said first and said second part of said closing sleeve, said membrane being suitable for being perforated by the second container during the mounting of the latter on the second part of the closing sleeve, characterised in that said connection system comprises a lid intended for closing off the second part of the closing sleeve before the connection system is used, said lid and said closing sleeve being obtained by means of a simultaneous method of moulding by injection of at least one plastic material, the lid being mounted on the second part of the closing sleeve once the lid and the closing sleeve have exited their respective moulds.

The present disclosure provides a feeding container device, including a bottle body having a bottle inner cavity, a first cover body at least partially disposed inside the bottle inner cavity and fixedly connected to the bottle body, a second cover body at least partially disposed inside the bottle inner cavity and having a cover inner cavity, a sealing ring disposed inside the bottle inner cavity and blocking the cover inner cavity, and a feeding device fixedly connected to the second cover body, the second cover body is mounted to the bottle body, the sealing ring is detachably connected to the second cover body and abuts the first cover body; when the second cover body moves away from the bottle body, the first cover body causes the sealing ring to separate from the second cover body, and the first sealed chamber communicates with the second sealed chamber.

A mixing cup for mixing and dispensing a mixed beverage is described. The mixing cup is designed to attach externally to a primary container that holds a primary liquid. The mixing cup contains a secondary liquid in fluid separation from the primary liquid until the two liquids are mixed, as a result of the user drawing the primary liquid from the primary container, in a mixing chamber of the mixing cup and the mixture is dispensed to the user. The flow of the secondary liquid into the mixing chamber may be adjustable by the user.

A cap assembly for a refill container, including an interface member and a movable sealing element retained in the interface member. The interface member may include a socket, a conduit arranged inside the socket forming a discharge opening, and a connecting wall extending between the socket and the conduit. The interface member may further include at least one abutment element arranged inside the conduit, the abutment element cooperating with the sealing element to position it in a closed position in which the discharge opening is sealed. The sealing element may include a body with a first end including a cap. The body and/or the cap may include a lateral wall with a sealing surface arranged inside the conduit.
