The present utility model relates to a new structural arrangement for various packages and to various package opening systems which can be used with any compatible package, and pertains to the technical field of packages in general, providing very advantageous, practical, reliable and functional results, with the greater objective of allowing packages to be recycled, preserving the environment and nature, which is a general practice worldwide by large companies which look after their image. The package comprises a body (10) shaped as a bottle, provided with an inner flexible tube (11) with a bent upper end, forming an inverted U, the upper portion (12) of which is kept in the vertical position outside the bottleneck, a stopper (14) being also provided at the liquid outlet (13); the body (10) and the tube (11) are closed by a lid (15) provided with a vertical projection (16) that forms an inner channel for housing the upper portion (12). Other arrangements are provided in structural variants.

A foam generator for compression receptacles is configured such that liquid contents pumped by an internal pressure as a result of directly compressing a compression receptacle, having the liquid contents stored therein, are mixed with air in a gas-liquid mixing chamber and, at the same time, directly discharged in the form of foam. Accordingly, the foam generator not only is capable of preventing the corruption of the liquid contents, which are not in contact with any separate metal member, but also further improves product responsiveness, since the contents are instantly discharged in the form of foam by compressing the compression receptacle.

Aspects of the disclosure generally relate to lids for water bottles and water bottles having the same. The lid includes a lid body, a mouth piece coupled to the lid body, and a valve formed in the lid body. The valve is actuatable to selectively allow fluid flow therethrough. The disclosed water bottles include the preceding lid. The disclosed water bottles can be filled with a fluid without removing a lid from the water bottles.

A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.

A liquid container includes a container body including an inner space formed to accommodate a liquid therein and an opening formed at a top thereof to allow the liquid to flow into the inner space, an outer cap including a liquid port fastened to the opening and connected to the inner space, an inner cap inserted into the liquid port and fastened to the outer cap to open and close the liquid port to selectively connect the inner space to an outside, and a stopper fastened to the inner cap, protruding in an outward-radial direction to be held by a bottom end of the outer cap to limit a movement distance of the inner cap, and formed of an elastic material to allow the inner cap to be separable from the outer cap by a certain external force applied to the inner cap.

A plastic soft tube with a cap structure able to control outflow includes a tube main body, a main body connector having an outlet, and an outer cap. The main body connector is provided with an inner cap and a middle cap fitted on the inner cap. The inner cap includes a protruding post. The protruding post has a first passageway. A lower end of the protruding post is connected with a protrusion for the first passageway selectively to communicate with the outlet or not to communicate with the outlet. The middle cap has a post hole corresponding to the protruding post. The middle cap and the inner cap are movably mated with each other. When the middle cap is turned, the inner cap is brought to move up and down relative to the main body connector for controlling the outflow of the liquid or paste.

A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.

A closure assembly for a container filled or fillable with a pourable product includes at least a lid having a first rim, a ring member having a second rim facing the first rim and one or more coupling elements, each one being connected to the first rim and to the second rim. Each coupling element comprises at least one respective intermediate portion, one respective first curved portion connected to the first rim and the intermediate portion and one respective second curved portion connected to the second rim and the intermediate portion. The intermediate portion is inclined with respect to the first rim and/or the second rim.
