摘要:
A cartridge usable in a viscous-material dispenser includes a cylinder, a plunger in the cylinder, and a plurality of ribs extending radially from an outer surface of the plunger to an inner surface of the cylinder. The ribs are circumferentially separated by a plurality of clearances, and the ribs and the clearances extend in an axial direction. Each of the plurality of clearances is defined by two adjacent ribs. The ribs and clearances are configured to allow the venting of gas through the clearances during a beginning of a cartridge filling operation and to impede the movement of the viscous material through the clearances during a remainder of the cartridge filling operation such that, at an end of the cartridge filling operation, the ribs and bodies of the viscous material in the clearances form an airtight seal between the plunger and the cylinder.

A paint transfer system for both automatically and manually transferring paint from a paint container directly to a paint brush including a paint container member, a pump mechanism, and a paint brush apparatus coupled together in fluid communication wherein the paint brush apparatus includes a paint brush having a bladder member or housing member positioned and located within the paint brush adjacent to or within its bristle members as well as an optional valve control member for controlling and distributing the flow of paint to the bristle members. In some embodiments, a remote controller is positioned between the paint brush apparatus and the paint container member for allowing a user to selectively activate the flow of paint from the paint container to the paint brush apparatus. A variety of different pumping mechanisms are utilized for transferring paint from the paint container member to the paint brush apparatus.

Provided are methods and systems for applying materials at interface areas formed by fasteners and parts. Specifically, a material is delivered to an interface area such that at least a portion of a fastener remains free from this material. The interface area may be sealed such that the material is contained within that area. As such, a controlled amount of the material is dispensed in a precise location. An applicator used for this process may include a housing and inner guide slidably disposed within this housing. The material may be delivered through an annular flow channel between the housing and inner guide. The inner guide may be sealed against and, in some embodiments, centered with respect to the fastener. The housing may be sealed with respect to the part and, in some embodiments, may be rotated with respect to the part to redistribute the material at the interface area.

A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

One example of the present disclosure relates to a daubing device for applying viscous material to a fastener. The daubing device comprises a housing comprising a first internal face and a second internal face, separated from the first internal face by a longitudinal distance L. The daubing device further comprises a dispenser between the first internal face and the second internal face of the housing. The dispenser comprises a flexible wall. The daubing device also comprises a pressure-application device between the dispenser and the second internal face of the housing.

A cartridge (12) for a viscous-material dispenser includes a plunger (10) that is slidable within a cylinder (18). A seal body (104) forms between an outer circumferential surface (82) of the plunger and an inner circumferential surface (84) of the cylinder when a viscous material flows into a radial tubular clearance (106) that continuously extends both axially and circumferentially between the outer circumferential surface and the inner circumferential surface. Ridges (100) may be formed on the outer circumferential surface of the plunger to guide the inflowing viscous material and facilitate the formation of the seal body.
摘要:
A sealant tube for use in a pneumatic sealant gun for reducing or eliminating air bubbles in the sealant being dispensed. The sealant tube may fit within a hollow sleeve of the pneumatic sealant gun and contains sealant and a slidable plunger. The tube body may include an inner surface, an outer surface opposite the inner surface, a first opening, a second opening opposite the first opening, and pressure release openings formed through the tube body, such that air from a pressurized air source flows into the tube body and between the tube body and the hollow sleeve during use of the pneumatic sealant gun, equalizing pressure on the inner surface and the outer surface of the tube body. A seal or gasket may also be located proximate the second opening of the tube body, for forming an airtight seal between the hollow sleeve and the tube body.
摘要:
A dispensing apparatus includes two cylindrical sleeves, two flexible film pack bags disposed within the sleeves, the two film pack bags having an integrally formed rigid face plate bonded therewith, the face plate having a discharge nosepiece integrally formed therewith, the discharge nosepiece having a partition internally configured to maintain separate flow streams from the film pack bags. Two shuttles are slidingly disposed in the sleeves. Push rods are disposed in operable communication with the shuttles. At least one piston is disposed in operable communication with the push rods, the piston configured to drive the push rods. A holder is disposed proximate a front end of the sleeves, the holder configured to restrain the face plate during dispensing of a flowable material. A mixer is configured to be in fluid communication with flow streams from the film pack bags. A material applicator is disposed in fluid communication with the mixer.
摘要:
An improved applicator for applying resin adhesive to a crease in fabric or an article of textile such as clothing in which a nozzle is located at the distal front end of the cartridge and a guide is located behind a receiver head. The receiver head is attached to the rear end of the cartridge.
摘要:
A system and method for dispensing sprayable material such as paint and other liquefied products. The system includes a dispenser such as a marking stick or other commercially available dispenser. The dispenser is configured to accept a container housed inside a cartridge and filled with sprayable material. The sprayable material is sprayed through a valve and spray tip at one end of the cartridge. An electrically powered motor assembly is removably coupled to the cartridge. The motor is used to power a pump that is incorporated in the cartridge to draw the sprayable material from the container. The material is pumped from the container and delivered through a tube to a spray head. The pressure generated by the pump inside the container and the tube are sufficient to spray the product through the valve and spray tip when valve is opened.
