The present disclosure relates to a metering and mixing device including a cartridge holder (1) and a cartridge (2). A surface-to-surface, and also positive and non-positive connection exists between the cartridge and the holder. The present disclosure also relates to a method for coating substrates with two- or multicomponent coating media, in which the metering and mixing device is used.

The invention relates to devices and methods of a puncturing nozzle head for safe and efficient release of fluid when used in assembly with a caulking device or any other fluid dispensing devices. The puncturing nozzle head is disposed over a barrel of the caulking device as a cap. The puncturing nozzle head is formed of a dispensing tube with a base plate. For example, the dispensing tube may be a conical shaped tube extending from the base plate. A plurality of puncturing rods may be disposed at an inner surface of the base plate. For example, the puncturing rods are configured to puncture a sausage pack containing caulking material which is loaded into the barrel of the caulking device. A nozzle head lock ring is provided to lock the nozzle head in position to the barrel.

A side-by-side cartridge assembly for dispensing a first fluid and a second fluid includes a first cartridge body and a second cartridge body having first and second cartridge coupling elements, respectively. The first cartridge body extends along an axial direction and has a radial boundary or periphery transverse to the axial direction. The first cartridge has a first neck portion of a neck, and the second cartridge has a second neck portion of the neck. The first neck portion projects from the first cartridge body such that the first neck portion is within the radial boundary or periphery of the first cartridge. As such, the first cartridge coupling element operatively connects to the second cartridge coupling element to secure the first cartridge to the second cartridge and form the neck for discharging a first fluid and a second fluid.

Described are metering dispensers having a body configured to hold a flowable composition in a chamber, a drive screw coupled to the body, and a plunger threadingly coupled to the drive screw. The plunger includes at least two annular lips that form a fluid seal with the chamber as the plunger travels along the drive screw through the chamber. A base is rotationally coupled to the body with a cam that contacts at least one tab extending externally from the body so that the tab enters at least one low point on the cam by traveling over a trailing edge of the low point, and the trailing edge then prevents the tab from exiting the low point in the direction of the trailing edge.

The present disclosure relates to an application system comprising a cartridge having at least one container with a respective outlet, and a closure element that can sealingly close the outlet of the at least one container when the cartridge is in the delivery state. When in the storage state, the cartridge sealingly closes the closure element. When the cartridge is in the state of use, the closure element can be removed therefrom and an accessory can be connected to the outlet of the at least one container. According to the invention, the cartridge or the closure element comprises, in the delivery state, a connecting element which cannot be removed without being damaged, and the cartridge or the closure element, in the storage state, is connected via a connecting element that cannot be removed without being damaged, to a closure element or the cartridge.

An example fluid applicator device includes an applicator assembly, and a reservoir assembly configured to store a fluid and is rotatable, relative to the applicator assembly, to control a valve mechanism that controls a flow of the fluid from the reservoir assembly to the applicator assembly, wherein the applicator assembly is configured to apply the fluid to a surface.

An adhesive deliver apparatus includes: a separable holder having a flexible press region thereon and comprising an interior receiving chamber for placing the adhesive tube; a support tube having a substantially elongated shape and comprising a proximal end and a distal end; a connector connected with the proximal end of the support tube and arranged to operably connect with a nozzle of the adhesive tube; and an inner tube positioned within the support tube and comprising an inlet end connected with the connector and an outlet end approximating to the distal end of the support tube; wherein when the press region is pressed to cause an interior surface of the press region to press the adhesive tube, the adhesive fluid will be squeezed out from the adhesive tube and transmitted through the inner tube from the inlet end to the outlet end.

An adhesive deliver apparatus includes: a holder; an adhesive tube, containing an adhesive fluid and positioned inside the holder, wherein the adhesive tube comprises a nozzle and a nozzle seal formed on the nozzle; a support tube comprising a proximal end and a distal end; a connector, arranged to operably connect with the proximal end of the support tube; and an inner tube, positioned within the support tube and comprising an inlet end connected with the connector and an outlet end approximating to the distal end of the support tube. When the connector is inserted into the holder, a portion of the connector would break through the nozzle seal. When the holder is pressed, the adhesive fluid will be squeezed out from the adhesive tube and transmitted through the inner tube from the inlet end to the outlet end.
