Abstract
An outlet portion for nasal rinsers includes an outlet end, a connection end and a nozzle shaped channel, showing a restriction and an expanded outlet, in between.
Claims11
An outlet portion (1) for a nasal rinser, comprising:
- an outlet end (2), a connection end (3) and a nozzle shaped channel (4) between the outlet and connection ends configured for use as an outlet portion of a nasal rinser,
- the outlet end, the connection end, and the nozzle shaped channel being a unitary structure of one material,
- the nozzle shaped channel (4) having an internal hourglass shape comprising a channel restriction section (5) and an expanded channel outlet section (6), wherein,
- the outlet end terminates with a distal end of the expanded channel outlet section,
- the expanded channel outlet section expands toward the outlet end with a maximum interior diameter of the expanded channel outlet section being located at the distal end of the outlet end,
- in use, when a liquid entering the connection end is pressed through the restriction section, a pressure will increase when the liquid passes through the restriction section and a velocity increase when the liquid reaches the expanded channel outlet section so that the liquid leaves the outlet end under turbulent flow so that the liquid fills out a nasal cavity while avoiding a jet spraying directly on a mucous membrane of the nasal cavity,
- the nozzle shaped channel is housed in an enlarged circumferential portion (12) shaped to seal against edges of an interior of a user's nostril,
- an exterior of the enlarged circumference portion (12) is droplet or balloon shaped,
- an inner diameter of the expanded channel outlet section (6) is greater than an inner diameter of the channel restriction section (5),
- the connection end comprises an interior portion shaped to fit onto a conical tip,
- the connection end, the nozzle shaped channel, and the outlet end together define a straight passageway extending through a longitudinal axis from the outlet end to the connection end, and
- a largest cross-sectional exterior diameter of the connection end being less than a largest cross-sectional exterior diameter of the enlarged circumferential portion (12).

An outlet portion (1) for a nasal rinser, comprising:
- a longitudinal axis and a channel extending throughout the longitudinal axis from a channel inlet (3) terminating a first distal end of the channel to a channel outlet (2) terminating a second, opposite distal end of the channel;
- the entirety of the outlet portion being a unitary structure of one material,
- an enlarged circumferential portion (12) housing an nozzle shaped channel portion (4) and including the channel outlet (2),
- the nozzle shaped channel portion (4) comprising a restriction section (5) connecting to an expanded channel outlet section (6) that expands towards and terminates at the distal end of the channel outlet (2) with the expanded channel outlet section increasing in interior diameter toward the second, distal end of the channel so that a maximum interior diameter of the expanded channel outlet section is located at the second, distalmost end of the channel,
- the nozzle shaped channel portion (4) being located in a part of the channel nearer the channel outlet than the channel inlet;
- and
- a connection end (3) connected to the enlarged circumferential portion (12) and including the channel inlet, the connection end comprising an interior portion shaped to fit onto a conical tip, wherein,
- a largest cross-sectional exterior diameter of the connection end is less than a largest cross-sectional exterior diameter of the enlarged circumferential portion (12),
- in use, when a liquid entering the connection end is pressed through the restriction section, a pressure will increase when the liquid passes through the restriction section and a velocity increase when the liquid reaches the expanded channel outlet section so that the liquid leaves the outlet end under turbulent flow so that the liquid fills out a nasal cavity while avoiding a jet spraying directly on a mucous membrane of the nasal cavity,
- the nozzle shaped channel portion is located within an end portion having a droplet or balloon exterior shape, and said outlet portion is configured for use as an outlet portion of a nasal rinser.

- an enlarged circumferential portion (12) housing a nozzle shaped channel portion (4) and including the channel outlet (2),
- the entirety of the outlet portion being a unitary structure of one material,
- the nozzle shaped channel portion (4) comprising a restriction section (5), the nozzle shaped channel portion (4) being located in apart of the channel nearer the channel outlet than the channel inlet,
- the restriction section (5) connecting to an expanded channel outlet section (6) that expands towards and terminates at the distalmost end of the channel outlet (2) with the expanded channel outlet section increasing in interior diameter toward the second, distal end of the channel so that a maximum interior diameter of the expanded channel outlet section is located at the second, distalmost end of the channel;
- and
- a connection end (3) connected to the enlarged circumferential portion (12) and including the channel inlet, the connection end comprising an interior portion shaped to fit onto a conical tip, wherein,
- a largest cross-sectional exterior diameter of the connection end is less than a largest cross-sectional exterior diameter of the enlarged circumferential portion (12),
- in use, when a liquid entering the connection end is pressed through the restriction section, a pressure will increase when the liquid passes through the restriction section and a velocity increase when the liquid reaches the expanded channel outlet section so that the liquid leaves the outlet end under turbulent flow so that the liquid fills out a nasal cavity while avoiding a jet spraying directly on a mucous membrane of the nasal cavity,
- the nozzle shaped channel portion is located within an end portion having a droplet or balloon exterior shape, and
- said outlet portion is configured for use as an outlet portion of a nasal rinser.
