A device for dispensing a liquid from a container is disclosed, comprising: an engine, comprising a nozzle and a pump for transferring liquid from the container to the nozzle; a trigger, moveable between a first position and a second position, connected to the pump for actuating the pump when brought from the first to the second position, and connecting means, for connecting the engine to the container characterized by
a slider with at least one restricting element, slideable between a non-restricting position, in which the trigger is moveable between the first and second position, and a restricting position, in which the at least one restricting element restricts the movement of the trigger between the first and the second position.

A connection system between a dispensing head and a bottle of a trigger dispensing device includes a skirt having a seat configured as an inlet on an inner surface, and a neck having a rib protruding from an outer surface. In a relative assembled position, the rib is angularly aligned with the seat while, outside of the relative assembled position, the rib constitutes an impediment to axial insertion of the skirt on the neck.

According to some illustrative embodiments, an angularly adjustable spray nozzle is employed that includes: a base section having a water flow path extending lengthwise there-through; a head section aligned at an end of the base section and rotatably mounted to the base section; wherein a flow path through the base section is inclined at an angle to a flow path through the head section such that when the head section is rotated a predetermined extent relative to the base section, the spray device is moved between a substantially straight configuration of the head section with respect to the base section and an angular configuration of the head section with respect to the base section; wherein the head section includes a rotatable turret assembly having a plurality of selectable spray type discharge ports and a sleeve to which the rotatable turret assembly is mounted, the rotatable turret assembly including labels on a periphery thereof corresponding to respective ones of the selectable spray type discharge ports, and the sleeve having a plurality of windows through which the labels are viewed when aligned; and wherein the spray device is configured such that when the spray device is oriented in a generally horizontal use position a respective one of the labels corresponding to a selected spray type is displayed within a respective one of the windows that is located at a top side of the sleeve whether the spray device is in the substantially straight configuration or in the angular configuration.

A bayonet connection structure between a container mouth portion and a cap is disclosed. The cap includes multiple slip prevention claws spaced apart from each other. One of the slip prevention claws is elastically displaceable in a radial direction. A rotation prevention projection is provided between the elastically-displaceable slip prevention claw and the other slip prevention claws. The mouth portion has a hollow cylindrical portion with an outer circumferential surface provided with multiple slip prevention claw (SPC) engagement portions for the slip prevention claws. The SPC engagement portions are as many as the slip prevention claws. Each of the SPC engagement portions has an end in a clockwise direction provided with a rotation prevention stopper. The mouth portion includes a rotation prevention rib to be got over by the rotation prevention projection of the cap when the cap is rotated.

A vessel cap of cosmetics includes a coupling member formed on an inner circumferential surface thereof with a female screw part such that the female screw part is engaged with a male screw part formed on an outer circumferential surface of an opening formed in an upper portion of a vessel which receives liquid-phase contents, a spuit tube which is coupled to the coupling member to suck and discharge the contents received in the vessel, and a pumping unit of the spuit tube, which sucks the contents into the spuit tube after inserting the spuit tube into the vessel in a state that internal air of the spuit tube is partially discharged. The spuit tube is inserted into high-viscosity and liquid-phase contents received in the vessel after the internal air is discharged from the spuit tube, thereby previously preventing the discharged air from being introduced into the spuit tube.

A head (4) of a trigger dispensing device for liquids includes an auxiliary body (30) for the connection with a neck (10) of a bottle (2). The auxiliary body (30) includes a closure base (32) suitable to close a mouth (13′) of the bottle (2) and dual constraints suitable to snap-engage with the neck (10) forming between the auxiliary body (30) and the neck (10) a constraint both to the relative rotation and to the separation thereof.

A connection system between a head and a bottle of a trigger dispensing device includes a main skirt having a first flexible tab and a neck (2b) having a first sloping plane and a first pocket. The first flexible tab extends circumferentially from a first end to a second end, and the first end is joined to an annular wall by a closing wall. The system also provides for an auxiliary window obtained through the annular wall of the main skirt, and a rigid auxiliary tooth of the neck, suitable to snap into the auxiliary window.

The present invention provides an improved pump assembly incorporating a liquid pump and an air pump and which pump includes a flexible annular diaphragm member coaxially about a piston-forming element forming a component with the liquid pump.

A product dispenser is provided that includes a container within a shell, and a pump and insert for dispensing the product. A spring biases the container and pump away from the tip of the shell. The bottom of the container is pushed up relative to the shell to activate the pump, thereby dispensing the product.
