In one aspect, the invention provides a fluid dispenser comprising a housing configured to receive a means for pressurizing and a disposable fluid bag, and a nozzle towards a distal end. A means for flow control comprising a tubular body whose longitudinal axis coincides with the longitudinal axis of the nozzle having a diameter that tapers from the side distal to the nozzle towards the nozzle is provided. The tubular body is configured to move along its longitudinal axis such that a volume of a gap between the tubular body and the nozzle is varied thus controlling the flow rate. Further, an adapter configured to be fitted onto the nozzle capable of receiving at least one applicator is provided. The fluid dispenser of the invention is capable of being used in a variety of situations in a facile manner, replacing several different devices to be used for individual applications.

A blister pack may include a containing body with an opening; and a lid sealed over the opening and provided with a weakening pattern, wherein a width of the lid at the weakening pattern is thinner that a width of the lid elsewhere, and wherein the lid is configured to burst at the weakening pattern when the blister pack is subjected to pressure, so as to allow liquid content inside the containing body to be discharged out of the blister pack through the burst weakening pattern. A blister pack holder is also disclosed.

The present invention surrounds a dispenser and means for dispensing viscous fluids, such as those associated with cannabis extracted compounds. More particularly, the dispenser of the present invention is a one-handed controlled dispenser device for viscous fluids with a replaceable cartridge to allow a user to selectively install and use different cartridges containing different fluids as desired or as needed.

The present disclosure provides an environment-friendly press bottle integrated with a bellows spring and equipped with an outer shell, comprising: an inner bottle of which the lower end is integrated with the upper end of a bellows spring; the lower end of the bellows spring is a closed structure; the upper end of the inner bottle is necked to form a connector; the aperture in the middle of the connector is fitted with a nozzle; a step that fits onto the connector and limits its position is disposed on the central outer side of the nozzle; an annular flange that snaps into the corresponding position on the inner surface of the connector is disposed on the outer side of the lower end of the nozzle, and external threads are provided on the outer surface of the connector; a cover lid is provided with internal threads and is connected to the external threads of the connector; the inner bottle is tightly nested in the outer bottle that serves as an outer shell. The present disclosure integrates the body of the inner bottle with the bellows spring, which significantly simplifies the structure, increases effective volume, saves material, and guarantees recycle of all parts of the device when the content is exhausted. The device is particularly suitable for the packaging of cosmetic products in lotion form.

A paint dispenser is described. In one embodiment, the paint dispenser can comprise a paint tube and a body. The paint tube can comprise an opening. The body can connect with the paint tube. The body can be capable of containing paint dispensable from the opening. Further, the body can comprise a pair of rail tracks, a pair of rack tracks, a pair of rails, a pair of racks, a pair of pinions, a pair of grips, a pair of axes, a pair of torsion spring, and a button. Each of the rails can be mounted within each of the rail tracks. Each of the racks can be mounted within each of the rack tracks. The pair of pinions can be at the center of middle layer of the body such that each of the pair of racks can come in contact with the outer edges of each pinion.

A container is provided, including a tubular body having an open first end and a second end defining a receptacle to receive an elongate storage unit; and a retaining frame within the receptacle to receive and retain the unit, movable between a first configuration to engage a retaining surface of the unit to retain it within the receptacle, and a second configuration in which it is released from engagement with the frame for removal from the container, the frame including a supporting rim circumscribing the first end; and a flexible tab depending from the rim and projecting radially into the receptacle, such that in the first configuration a distal end of the tab is configured to engage the retaining surface, and when the frame is moved from the first to the second configuration, the tab is bent towards a peripheral wall of the body and away from the retaining surface.

A self-priming-pump-equipped packaging bottle includes a tubular bottle body containing therein an upper seal assembly, a lower seal assembly, and piston from top to bottom. The upper and lower seal assemblies and the tubular bottle body form a closed material-feeding chamber. The lower seal assembly, the piston, and the tubular bottle body form a closed material-storing chamber. The lower seal assembly primarily has a seal seat with a through hole and an elastic sealing gasket covering the through hole from above. The upper seal assembly has an umbrella-shaped member, a hollow material-feeding column, a support post, and an end sealing cap. The end sealing cap is fixed in the umbrella-shaped member through the support post. The hollow material-feeding column's bottom surface, the support post, and the end sealing cap form a material outlet. The umbrella-shaped member lower end is in interference fit with the seal seat.

The present invention provides a plunger (20) for a dispenser, the plunger including a large diameter body portion (23) provided with ring-shaped contact surfaces (24, 25) that contact an inner wall surface of a syringe, a rear opening (26) formed in a backside of the large diameter body portion (23), and a small diameter body portion (22) provided with a front opening (28), wherein the front opening (28) is formed in a size allowing a liquid material to be directly pressed by pressurized air, and allowing at least the plunger (20) to move following a fall in water head position, which is caused with discharge and consumption of the liquid material. With those features, the liquid material can be prevented from adhering to the inner wall surface of the syringe, and the liquid material in the syringe can be prevented from flowing backwards.

A flowable material dispenser including a barrel defining a cylindrical interior volume for holding a flexible material bag containing a flowable material. A nozzle is attached to the first end of the barrel for discharging the flowable material through a nozzle hole; and a closure is disposed on the second end. A center nut disposed on the closure holds a threaded drive rod threadably and rotatably inserted in the center nut. The drive rod includes an inner end and an outer end. Drive structure for imparting rotational forces to the drive rod moves the drive rod reciprocally and axially within the cylindrical interior volume of the barrel to twist and wring out flowable material contained within the flexible material bag.
