Abstract
A breakaway coupling assembly includes a male coupling and a female coupling. The male coupling includes ribs that flex portions of the female coupling as an insert of the male coupling is positioned within the female coupling. Once the insert of male coupling is positioned into the female coupling a predefined distance, the ribs snap into a circumferential retention groove of the female coupling to secure the male coupling to the female coupling and form a fluid seal. The male coupling is decoupled from the female coupling by pinching the female coupling to release the ribs from the retention groove.
Claims17
A breakaway coupling assembly, comprising:
- a male coupling including an insert section and a post section, and defining a first male coupling aperture and a second male coupling aperture connected by a male coupling internal channel, the insert section including a sealing gasket and a plurality of ribs, each including a snap-action surface;
- and
- a female coupling including a receptacle section and a female coupling post section, and defining a mechanically deformable first female coupling aperture and a second female coupling aperture connected by a female coupling internal channel, the receptacle section defining an insertion cavity including a sealing surface, a rib retention groove, and a retention surface;
- wherein, upon insertion of the male coupling insert section into the insertion cavity, the plurality of ribs deforms the first female coupling aperture and the retention surface engages with the first retention surface to draw the plurality of ribs into the rib retention groove, and the sealing gasket engages the sealing surface to form a continuous fluid flow path for fluid to flow between the male coupling internal channel and the female coupling internal channel;
- and
- wherein the first female coupling aperture forms a complete circular periphery shape, and, upon insertion, the plurality of ribs forces the first female coupling aperture to form an elliptical periphery shape.

A female breakaway coupling, comprising:
- a receptacle section defining an insertion cavity including a sealing surface, a rib retention groove, and a retention surface;
- a female coupling post section;
- and
- a mechanically deformable first female coupling aperture and a second female coupling aperture connected by a female coupling internal channel;
- wherein, upon insertion of a male breakaway coupling insert section into the insertion cavity, a plurality of ribs of the male breakaway coupling deforms the first female coupling aperture and the retention surface engages with a first retention surface of the male breakaway coupling to draw the plurality of ribs into the rib retention groove, and a sealing gasket of the male breakaway coupling engages the sealing surface to form a continuous fluid flow path for fluid to flow between the male breakaway coupling and the female coupling internal channel;
- and
- wherein the first female coupling aperture forms a complete circular periphery shape, and, upon insertion, the plurality of ribs forces the first female coupling aperture to form an elliptical periphery shape.

A method of coupling a male coupling to a female coupling to form a breakaway coupling assembly, the method comprising:
- providing a male coupling including an insert section and a post section, and defining a first male coupling aperture and a second male coupling aperture connected by a male coupling internal channel, the insert section including a sealing gasket and a plurality of ribs, each including a snap-action surface;
- and
- providing a female coupling including a receptacle section and a female coupling post section, and defining a mechanically deformable first female coupling aperture and a second female coupling aperture connected by a female coupling internal channel, the receptacle section defining an insertion cavity including a sealing surface, a rib retention groove, and a retention surface, wherein the first female coupling aperture forms a complete circular periphery shape;
- inserting the male coupling insert section into the insertion cavity;
- and
- allowing the plurality of ribs to deform the first female coupling aperture so that the first female coupling aperture forms an elliptical periphery shape and the retention surface engages with the first retention surface to draw the plurality of ribs into the rib retention groove, and the sealing gasket engages the sealing surface to form a continuous fluid flow path for fluid to flow between the male coupling internal channel and the female coupling internal channel.
