The present invention is directed to a Hair Pigment Dispensing (HPD) device that may be connected to the internet and intended for professional hairstylists to prepare their hair color formulations. Hair dying is a process that can take several hours and requires precise measurements, high attention to detail, and informed decision making. Not to mention, hair dying requires a large inventory of products to be readily available to the hairstylist. The present invention aims to decrease errors in product measurement, inventory size, and time spent mixing hair color ingredients to improve the overall experience for both the hairstylist and the client. Furthermore, the present invention provides the advantage of storing data from various client mixtures either locally or within a cloud server so that a customer can receive uniform coloring.

The hunting-attractant dispenser is an apparatus that allows only the attractant solution, which is immediately consumed by an animal, to be accessed. The apparatus includes a supply tank, an attractant slot, a wheel, and an axle rod. The supply tank contains attractant solution. The attractant slot allows an animal to access the attractant solution within the supply tank. The wheel delivers attractant solution from within the supply tank to the tongue and the mouth of an animal. Moreover, the wheel allows an animal to engage the apparatus and drink the attractant solution. The axle rod allows the wheel to rotate. Moreover, the wheel allows the attractant solution to continuously cover the wheel as the wheel rotates. The apparatus further includes a first elongated mounting brace and a second elongated mounting brace, both of which stabilizes the apparatus onto the ground.

A diffuser outlet duct for a pressurized container fitted with a valve, equipped with: a passage between a first end and a second end. The first end is configured to collaborate with the valve of the pressurized container. The second end is configured for expelling the product contained in the pressurized container. The passage is defined by a first section, a second section, and a junction connecting the first section and the second section. The first section begins begins at the first end and terminates at the junction. The second section at the junction and terminates at the second end. The first section extends over a first length (l1), and the second section extends over a second length (l2) The second length is less than 10 mm, preferably less than 9 mm, more preferably less than 8 mm.

An auto-reset dose release firing system (101) and a method of using same. The system can include an a stored energy device (109); a first plunger (103) movable between first, second, and third positions, the first plunger configured to be operatively coupled to a medicament canister (51); and a second plunger (104) movable between first and second positions; the first and second plunger being movable with respect to one another and shaped to define an evacuable chamber (185) therebetween. The first plunger and the second plunger can move together from their respective first positions to their respective second positions, due to a reduced pressure in the chamber, to cause a dose release valve (54) to fire. After firing, air can be allowed to move into the chamber to allow the first plunger to move with respect to the second plunger to its third position to allow the dose release valve to reset.

A pressurized chemical theft deterrent device includes a locking portion and a shackle. The locking portion includes a locking mechanism. The shackle includes a shackle wall. The shackle is configured to house a chemical deterrent within the shackle wall. The chemical deterrent is pressurized while being housed inside the shackle such that a breach in the integrity of the shackle wall causes an aerosolized release of the chemical deterrent.

Exemplary embodiments of dispensers and refill units are disclosed herein. An exemplary refill unit for a soap, sanitizer or lotion includes a non-collapsing container. The non-collapsing container includes a neck. An annular projection is located at least partially on the neck. A one-way valve is located proximate the annular projection. The one-way valve allows air to flow into the non-collapsing container once the vacuum pressure in the container reaches the cracking pressure of the one-way valve and the one-way valve prevents liquid from flowing out of the annular projection. In addition, a pump for pumping the contents of the container out of the container is also included.

Several pressure cartridges and activation mechanism arrangements are disclosed which are configured to use less manual force to rupture the cartridge than current pressure cartridges and activation mechanisms. According to some embodiments, the activation mechanism requires lower manual activation force by using the pressure in the cartridge to do part of the rupturing work. The cartridge can be filled with compressed gas such as nitrogen and argon, or supercritical fluids such as carbon dioxide, and can be used to propel or operate several types of devices and mechanisms including medical drug auto-injectors, paintball guns, tire emergency inflation kits, and inflatable life vests.
