The invention relates to a dispenser 20 for the spray delivery of a preparation 18. The dispenser comprises: a reservoir 22 suitable for containing the preparation 18, a mechanical pump 24, a load chamber 26, a nozzle 28 having a delivery axis, and a delivery cone 30 having an axis. The mechanical pump is able, whenever operated: to take a predetermined amount of preparation from the reservoir, to supply said amount of preparation to the load chamber upstream of the nozzle, and to create a delivery pressure in the load chamber. The nozzle is able to deliver said amount of preparation in the form of an aerosol spray 180. The dispenser according to the invention is characterized in that the delivery cone comprises, in the proximity of the nozzle, at least one through-hole 320 suitable for putting the inside of the delivery cone into communication with the surrounding environment.

Disclosed herein are various embodiments of a pump mechanism comprising a rigid structure having an open end and a closed end, a plunger disposed in the open end of the rigid structure, and a flexible, fluid-proof sheet of material attached to an inner wall of the rigid structure and bonded to the head of the plunger such as to form a fluid barrier between the interior of the rigid structure and the plunger. Movement of the plunger toward the closed end of the rigid structure causes a rolling corner to be formed between the head of the plunger and the rigid structure and a fluid contained within the pump chamber to be forced out of the pump chamber via a fluid port defined in the closed end of the rigid structure.

A trigger sprayer having a venting system including a piston bore and a vent bore at least partially contained therein, the vent bore including at least one vent port; a piston and vent piston are moveably seated in the piston bore and vent bore, respectfully, the vent piston including at least one annular seal and a vent path port, the vent path port and vent port in gaseous communication when the vent piston is actuated and moved over the vent port.

A drink container and related methods are disclosed hereon. A method of making a drink container includes (a) providing a beverage bottle for holding a beverage for human consumption; (b) forming a threaded mouth in the beverage bottle, the threaded mouth meeting government safety standards for drink containers; (c) providing a removable cap; (d) forming a threaded recess in the removable cap, the threaded recess meeting government safety standards for caps for drink containers, the removable cap further having a sprayer and a dip tube; and (f) threading the removable cap onto the beverage bottle and causing the dip tube to extend into the beverage bottle.

A chemical resistant elastomeric cap that can be secured to the head of a pump type liquid dispenser with a delivery nozzle that can be used to seal off the dispenser nozzle to prevent fluid dripping from the end of the nozzle and to prevent air from reaching the end of the nozzle to dry fluid in the nozzle outlet orifice and/or the nozzle tip. The cap is one piece and has an attachment ring of elastomeric material than can to fitted around the dispenser head to retain the cap with the dispenser and the attach bottle whether the cap is fitted over the nozzle or free from the nozzle.

The invention is intended for the organization of an automated process for spraying of liquid means of chemical treatment from unmanned vehicles, for example, in precise farming systems. The invention provides the use of a replaceable, marked and hermetically sealed liquid subsystem with integrated pumping chambers in a spraying device together with an integrated self-diagnosis system allowing to ensure personnel safety and the accounting of the resources of main components of the spraying device. All this in combination enables to create fully automated spraying systems.

A method for evaluating the pump actuation for a pump dispenser that comprises two sub-units which can be moved manually towards one another and a pump which has a pump chamber that can be made smaller by moving the sub-units from a first end position into an actuated second end position. The force with which the sub-units are moved towards one another is detected by a force sensor during movement of the sub-units. The curve over time of the detected force is evaluated such that an increase in force is identified which is characteristic for reaching the actuated second end position. Depending on whether the increase in force was detected, a signal which is characteristic for the result is haptically, acoustically and/or visually output and/or transmitted via a wireless interface to an external display apparatus, by means of an output device.

Disclosed are self-sealing actuators and pumps for distributing fluids such as personal care products. The actuator can include a nozzle having an outlet that is opens and closes via movement of a plug. A limit rod is configured to engage with the plug and upon actuation the assembly opens a passage for the fluid to flow through an inner channel of the limit rod and to the outlet. Upon de-actuation, the assembly closes the passage sealing the fluid within a closed environment to prevent degradation and caking. Actuators and pumps as described protect the performance of active ingredients within the fluid and prevent the nozzle and outlet from blocking with dried or caked fluid.

A spray bottle assembly includes a bottle having a neck, and a spray head assembly having a base cap configured to removably attach to the neck. The base cap has a feature that rotationally locks the base cap relative to the neck to constrain the spray head assembly in a predetermined plane. A multi-label system for a spray bottle includes: at least one strip, the strip including connected labels with differing information printed on each side, each label including a ring for positioning on a neck of the spray bottle. A pumping mechanism for a spray bottle includes: a unibody plunger having a sleeve section that variably inverts and overlaps an end thereof thus defining an internal volume that varies with the disposition of the sleeve section relative to the end. A pivoting head section that allows servicing of functional seal components.
