A dispensing head for a supply tube that enables material to be evenly applied adjacent to the peripheral edge of a thin structure, such as a vehicle door. The dispensing head has a first end with a first opening and a second end with a discharge opening. A guide extends from the second end. The guide includes a descending element and a lateral foot element, wherein the bottom surface of the second end, the descending element, and the lateral foot element define three sides of an open gap space. The dispensing head is attached to a supply tube. The thin structure is positioned within the guide. The hook shaped guide positions the discharge opening a set distance from the application surface on the thin structure. The guide is moved along the peripheral edge where the material can be dispensed evenly at a set distance from the peripheral edge.

An applicator is proposed comprising an outer sleeve having a cylindrical inner surface and a receiving space for a flowable substance to be applied and an inner sleeve which can be displaced in the outer sleeve and in which a frangible ampule containing the flowable substance is disposed and which has an opening connecting an interior of the inner sleeve to the receiving space of the outer sleeve and an activation means upon whose activation the ampule breaks.

A dispense tip receives material from a material source and applies the material to a substrate. The dispense tip includes a hub having a body that defines a proximal end, a distal end opposite the proximal end along a central axis, a passage extending through the body, an inner surface facing the passage, and at least three radial features each extending 360 degrees about the central axis and radially into the body from the inner surface. The dispense tip also includes a tube defining a central passage extending therethrough, where the tube is at least partially received within the passage such that the central passage of the tube is in fluid communication with the passage, and an adhesive is disposed between the tube and the inner surface of the hub. The adhesive is received within the at least three radial features and secures the tube to the hub.

A system is disclosed for producing a mixture to deliver to a treatment site. The system can include a first chamber with an inner cavity including a first constituent and an outer cavity concentric with the first cavity and including a second constituent. A partition can be openable and separate the first and second cavities. A second chamber can include a third constituent and be concentric with the first chamber. Moving the first chamber and/or the second chamber relative to the other can cause the partition to open so that the first constituent and the second constituent mix with each other to form a first mixture. Applying a force to the system can cause the first mixture and the third constituent to egress through distal portions of the first and second chambers and mix together to form the mixture for delivery to the treatment site.

A cutter and a caulking gun having the same are provided. The cutter is configured to be connected to a caulking gun having a connecting member which is disposed on the caulking gun and includes a first assembling portion. The cutter includes a main body including a base and a cutting portion connected with the base, the cutting portion includes a cutting blade, and the base includes a second assembling portion configured to be detachably connected with the first assembling portion.

A compound applicator includes a nozzle assembly including a nozzle opening and a plug movable relative to the nozzle opening between a first position in which the nozzle assembly is in a closed state, and a second position in which the nozzle assembly is in an open state, a spring configured to bias the plug into the first position, a cylinder configured to receive and store a compound material, a main housing, a handle rotatable relative to the main housing, a pull rod having a first end coupled with the plug, and an input mechanism located at least partially within the handle and/or the main housing and configured to convert rotational motion of the handle into axial movement of the pull rod, thereby moving the plug from the first position toward the second position. The spring pulls the pull rod such that the pull rod is biased into tension.

A disposable roof coating applicator includes a nozzle that is attached to a collar. The nozzle and collar are selectively attachable to a body that has an interior space and is formed by at least one side wall having an exterior wall and an interior wall. The coating applicator also includes a plunger that is movably disposed within the interior space of the body. The coating applicator may include a locking mechanism about the applicator's collar that selectively engages a stud provided on the body's exterior surface, selectively locking and unlocking the nozzle and collar assembly to the body. The disposable roof coating applicator is configured and otherwise designed to take in, store and transport approximately ½ to 2 gallons of viscous material to a roof seam before neatly and uniformly expelling the viscous material to the seam or joint.

A method of applying a two-part dental sealant is described comprising providing a syringe device (1) comprising a cartridge (10) including first and second chamber. The first chamber contains a first part of a dental sealant comprising a (meth)acrylate resin and an oxidizing curing agent. The second chamber contains a second part of a dental sealant comprising a (meth)acrylate resin and a reducing curing agent that reacts with the oxidizing curing agent of the first chamber. The first and/or second part of the dental sealant further comprise a single component or multiple components that neutralize acid and promote remineralization. The syringe device comprises a dispensing nozzle (17) comprising a static mixer and an outlet at one end of the cartridge and a plunger (20) at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.

Storage and mixing systems and methods for pasty multicomponent polymethylmethacrylate bone cements, the systems and methods comprise a first tubular cartridge with a first cylindrical internal space containing a first starting component, a first dispensing plunger, a second tubular cartridge that is arranged within the first tubular cartridge. The external wall of the second cartridge touches against the internal wall of the first cartridge and is attached to the internal wall of the first cartridge, whereby the second cartridge contains a second starting component and has a second dispensing plunger arranged in it, whereby a pressing device with a clamping edge for compressing the second cartridge that can be propelled axially in the internal space of the first cartridge is arranged, as seen from the cartridge head, behind the first dispensing plunger and the second dispensing plunger. The pressing device can be propelled appropriately in the direction of the cartridge head such that the second cartridge is being progressively compressed axially during the motion of the pressing device such that, in the process, the first dispensing plunger and the second dispensing plunger are propelled in the direction of the cartridge head.

The present invention relates to a system of converting dispensing packs with two or more compartments with a fixed volume to modified ratio dispensing packs or dispensing packs with one compartment to multiple compartment dispensing packs using modified compressible foam or fibre inserts.
