A device for dispensing a fluid product, comprising a rigid cylindrical body having a vertical main axis, a rigid piston which is oriented essentially horizontally and which can slide vertically inside the body, and an upper extraction wall which closes the upper end of the body. According to the invention, the body, the piston and the upper wall define a space that is intended to be filled with the product to be dispensed. In addition, the upper wall comprises a slotted cover that can open in order to connect the space to the exterior. The upper wall is elastically deformable and can deform into the space when a pressure is exerted manually on the upper wall, so as to increase the pressure inside the space and cause the slotted cover to open.

A resiliently deformable member for use in an apparatus for dispensing a viscous material from a container, such as an apparatus consisting of a container for holding the viscous material and a dispensing gun. The resiliently deformable member has a relaxed state and a compressed state. In use, the resiliently deformable member applies a force between the container and the dispensing gun to modulate the flow of the material from the container.

An electronic cigarette vaporizer that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the resistance of the heating element and (ii) uses an inference of temperature derived from that resistance as a control input. The temperature of the heating element may be inferred from data stored in the electronics module that has been empirically obtained for a specific heating element design. The electronics module controls the power delivered to the heating element to ensure that it is no higher than approximately 130 C., plus an error tolerance.

An electronic cigarette vaporizer that includes an air pressure valve or device to enable excess air to escape from an e-liquid reservoir in the vaporizer during pressurized filling of the vaporizer with e-liquid. If the vaporizer includes a ceramic cell, then the air pressure device is the wall of the ceramic cell and the reservoir is the chamber arranged outside of the external wall of the ceramic cell.

A paint dispenser that continuously dispenses paint to a paintbrush is described herein. In one embodiment, the paint dispenser can comprise a body and a fastening device. The body can be capable of containing paint. The body can comprise a paint tube, and a button. The paint tube can be at the front end section of the body. The paint tube can comprise an opening wherein the paint can be dispensed. The button on the body can be capable of controlling the flow of the paint from the container to a paintbrush. The fastening device can be capable of mounting the body to the paintbrush.

A deodorant dispensing apparatus including a reusable product dispenser and a deodorant refill cartridge releasably coupled to the reusable product dispenser. The reusable product dispenser includes a cylindrical housing, a base, a telescope, and a spring. The base is rotatably coupled to the cylindrical housing and operably coupled to the telescope. The spring is operably coupled to a spring holster of the base and the telescope. The deodorant refill cartridge includes a refill barrel and refill plunger. The refill plunger is rotatably coupled to the refill barrel, which retains a deodorant product therein. The refill barrel includes a latching mechanism for releasably coupling the refill barrel to the reusable product dispenser.

A delivery system having a telescoping spring is used to drive a plunger. The telescoping spring includes a nested inner spring that uses the unused volume on the inside of an outer spring. The telescoping spring has a staged release of each spring. The inner spring is connected to a non-anchored end of the outer spring, and rides within a container located within an inner dimension of the outer spring. The spring constant K of each spring can be the same or different. The delivery system can be fully mechanical or implemented as a smart delivery system under electronic control.

An electronic cigarette vaporizer includes a heating element, an air pressure sensor and a microcontroller; the microcontroller stores, processes or determines the extent of each inhalation using signals from the air pressure sensor. The microcontroller can calculate the approximate e-liquid consumption from the extent of each inhalation or provide data that enables an external processor to calculate approximate e-liquid consumption. The extent of an inhalation is a function of one or more of: duration; peak flow rate; average flow rate.

An electronic cigarette vaporizer is not dis-assembled for filling with e-liquid, but is instead filled from a user-replaceable e-liquid cartridge. The vaporizer includes a front section comprising a wick and heating assembly but no e-liquid cartridge, the front section being removably fitted to a body of the vaporizer to enable a replacement front section to be used once the original wick or heating element starts to degrade, that replacement front section being supplied to the end-user with no e-liquid in it.
