A nozzle for a spray gun, in particular a paint spray gun, has at least one material nozzle having a hollow portion for the passage of material to be sprayed; a material outlet opening; and a disk element extending radially from the material nozzle and having at least one passage opening. The nozzle has at least one first baffle disk which is arranged on the disk element and has an inner and an outer circumference. The first baffle disk is arranged on the disk element directly, in particular without a sealing element arranged inbetween. The disadvantages that separate sealing elements have to be specially produced and may be lost or damaged, can thereby be avoided. The nozzle according to the disclosure and related nozzle sets, paint spray guns and methods for producing nozzles are functionally reliable, have only few individual parts and a compact design and are quiet.

A portable device for checking wind direction discharges a visible, and optionally scented, vapor stream into the atmosphere in a well-defined reference direction. In some embodiments, the device includes a power source, a vessel having an internal plenum chamber storing a volume of air, a reservoir containing a vaporizable agent, a vaporizing element associated with the vaporizable agent, and a pressure switch. The vessel is deformable to generate an airflow that operates the pressure switch to temporarily connect the power source to the vaporizing element, thereby energizing the vaporizing element to generate vapor. The airflow also carries the vapor into the atmosphere as a visible vapor stream flowing in the reference direction. The reservoir and vaporizing element may be carried in a cartridge removably mounted on the device. Other embodiments operate similarly, but use alternative means for generating gaseous flow to operate the switch and/or carry vapor into the atmosphere.

An extensible pesticide applicator is provided enabling application of both liquid and powdered insecticides to distal, out-of-reach areas. An extensible pole has a distal and a proximal end for manual wielding whereby a pair of nozzles is deployable proximal an out-of-reach habitat. Pressurization of ambient atmosphere into the extensible pole is enabled by a pump member and timed release of the pressurized ambient atmosphere to forcibly eject powdered and alternately liquid pesticide from the distal end is enabled by manual action effected to depress a trigger member. Direct application of pesticide is thereby enabled to distal and out-of-reach habitat without a user coming into proximity with the habitat or the pesticide released.

A device (10) for packaging and dispensing a product comprises a container (12), a moveable piston (16) mounted inside the container (12) and delimiting one compartment (22) containing the product, and a dispensing member (14) mounted on the container (12) and comprising at least one outlet orifice (24) in communication with the compartment (22). The device (10) further comprises a pump system (18) mounted on the container (12) axially on the side opposite to the dispensing member (14) and comprising a push-button (28). Said pump system (18) is configured so that exerting a pressure on the push-button (28) results in a forward displacement of the piston (16) inside the container (12) towards the dispensing member (14) and subsequent releasing of said push-button (28) results in a backward displacement of said piston (16) away from said dispensing member (14).

Perfume compositions having controlled spatio-temporal olfactory profiles are described. The disclosure also relates also to a method of measuring said spatial-temporal olfactory profiles of said compositions.

The present invention disclosed herein relates to a container for discharging powder, in particular, a container for discharging powder having a structure wherein a discharging hole of a button part and a connecting hole of a stem are connected or dislocated according to rotation directions, and an opening/closing member is inserted into the stem inside the button part and ascends/descends according to a rotation of the button part, and thereby opens/closes a movement hole of the stem, such that it will solve inconvenience problems such as attaching/detaching the opening/closing member whenever using as well as prevent a risk of losing the opening/closing member, thereby providing user convenience.
