A contents container includes an inner container assembly which accommodates contents and discharges the contents to the outside by application of pressure, and an outer container assembly which accommodates the inner container assembly, wherein the outer container assembly may comprise: an outer container provided so as to surround at least a portion of the inner container assembly; a connection part which connects the outer container and the inner container assembly, and raises and lowers the inner container assembly by being raised and lowered along the outer container when rotated; and a rotation part which raises and lowers the connection part by a rotation operation.

A piston for a reservoir of a dispenser of a fluid product without air intake, and presenting a central axis X includes both sealing means and also guiding means. The sealing means extend in a plane orthogonal to the axis X and define a single external sealing line in a closed loop, distal from the axis X, capable of coming into contact with an inner wall of the reservoir 10. The guiding means include a base from which extends one or more tabs with free ends defining external guide points, distal from the axis X, capable of coming into contact with the inner wall of the reservoir.

A cartridge system for delivering an aqueous solution made with a mixture of an active material and a liquid medium, where the cartridge system includes a bottle-shaped container and a pump fastened to a neck of the container, where the container is filled with the liquid medium. The container includes a cartridge and an intake tube of the pump sealingly inserted in an upper side of the cartridge, where the active material is supplied to the cartridge through the intake tube. The cartridge is sealed from an exterior by a piston or a stopper, where the piston or stopper is movably arranged in a wall of the cartridge and configured to enter into an interior of the cartridge under reduced pressure produced by the pump and opens to the exterior of the cartridge so that the active material is mixable with the liquid medium.

Systems and methods are discussed herein for an optimal approach for wireless emergency alerting within cells of wireless communication networks by using a careful estimation of a true effective radius of each cell/sector to eliminate broadcasts falling short of alert area boundaries (with users in such gaps in coverage not receiving an alert despite being in the designated alert area). By utilizing true provisioning information of each cell/sector that is at least partly within the alert area boundaries to understand the true effective radii of particular cell sectors can be selected for broadcast of the alert such that the entire alert area is covered for broadcasting of the alert without excessive over-broadcasting, e.g., broadcasting excessively beyond the alert area boundaries. Alerts can then be broadcast within each selected cell sector.

Structures for retaining one or more accessory tools to a caulking gun are disclosed. The accessory tools include spatulas, utility knives, hangers, handles, and flashlights. In one embodiment, the retention structure is a mounting rail affixed to an elongate strap forming a portion of a carriage assembly of the caulking gun. The mounting rail includes a plurality of alternating projections and grooves extending along its length for removably mounting the accessory tool. The mounting rail includes a retention portion to securely attach the mounting rail to the dispensing device. The retention portion includes a pair of opposed legs extending from a central body, each leg including an inwardly facing pocket to engage and contain therein lateral edges of the elongate strap.

A pump dispenser includes an air cylinder, an air piston provided in the air cylinder to reciprocate, a liquid cylinder, a liquid piston provided in the liquid cylinder to reciprocate, a mixing chamber having a communication hole in an upper wall thereof and provided on the secondary side of the air piston and the liquid piston to mix a liquid material and air supplied by reciprocation of the air piston and the liquid piston, a porous body provided on the secondary side of the mixing chamber, and a nozzle including a flow path formed on the secondary side of the porous body and a discharge hole whose opening area is smaller than an opening area of the flow path to reciprocate thereby to cause the air piston and the liquid piston to reciprocate.

Aiming to provide an alternative method for dispensing pasty products loaded into a wide range of package massively used today throughout the world, the present invention for dispensing system for hollow round packages generally relates to the field of dispensing devices designed to preferably dispense pasty products that are currently loaded into packages made from the most diverse materials and that can be replaced by ecologically suitable hollow round packages which are produced as from recyclable materials such as aluminum, cardboard and/or any other structure viable for this purpose.
