  • Patent number: 11168821
    Abstract: An adapter for connecting a separated-outlet fluid cartridge to a single-inlet static mixer includes a locking portion and a connecting portion. The locking portion has at least one locking element to lockingly engage the mixer housing so as to inhibit rotation between the locking portion and the housing. The connecting portion is received within the locking portion and has first and second fluid inlet members to be coupled to respective first and second fluid outlets of the cartridge for receiving fluid from the cartridge, and a fluid outlet member is sealingly coupled to the mixer for directing fluid into the mixer. The locking portion is selectively rotatable about the connecting portion between unlocked and locked positions relative to the cartridge when the connecting portion is coupled to the cartridge. Consequently, the adapter advantageously enables dispensing with a separated-outlet fluid cartridge in combination with a single-inlet static mixer.

  • Patent number: 11040369
    Abstract: 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.

  • Patent number: 10641423
    Abstract: An adapter for connecting a separated-outlet fluid cartridge to a single-inlet static mixer includes a lock mechanism and a lock release mechanism. The adapter includes a connection portion that engages the mixer. The lock mechanism has at least one snap arm that lockingly engages the cartridge in a snap fit manner so as to secure the adapter to the cartridge in fluid communication. When in the locked position, separate fluids are evacuated from the cartridge into the mixer where they are mixed prior to dispensing. The lock release mechanism quickly and easily unlocks the at least one snap arm from the cartridge for allowing a user to separate the adapter from the cartridge. The adapter sealing engages with both the mixer and the cartridge so that fluid flowing from the cartridge to the mixer does not leak.

  • Patent number: 10427114
    Abstract: A flow shifter baffle for mixing a fluid flow having at least two components, a static mixer, and method of mixing are described. The flow shifter baffle includes a double divider wall element adjacent to a leading edge and a plurality of occluding walls coupled to the double divider wall element. The double divider wall element includes first and second generally parallel walls which extend across the entire transverse flow cross-section. The double divider wall element is configured to divide the fluid flow into a central flow portion and first and second peripheral flow portions. This division of the fluid flow using the double divider wall element and the plurality of occluding walls improves the mixing of separate components by producing a greater number of layers with less jumbling of the layers, when a layered composition of multiple components is delivered into the flow shifter baffle.
