Abstract
A static mixing tip includes a static mixer, a housing and a body. A head space is between the housing and the static mixer, a sealing lip on the base of the static mixer seals between the base of the static mixer and the housing, and a venting element is on the sealing lip of the static mixer or the housing. The venting element provides gas flow communication between sides of the sealing lip, and a gaseous connection between the head space and an exterior ambient atmosphere such that gases trapped in the head space between the housing and the static mixer can escape during normal operation and operation of the static mixing tip.

A static mixing tip comprising:
- a static mixer having a base;
- a housing having a base (60) and a body;
- a head space disposed between the housing and the static mixer;
- a sealing lip disposed on the base of the static mixer to provide a seal between the base of the static mixer and the housing;
- and
- at least one venting element disposed on the sealing lip of the static mixer or the housing,
- the at least one venting element is configured to provide a gas flow communication between two sides of the sealing lip, and a gaseous connection between the head space and an exterior ambient atmosphere outside the static mixing tip such that a portion of gases trapped in the head space between the housing and the static mixer has a pathway to escape to the exterior ambient atmosphere during normal operation and operation of the static mixing tip.
A static mixer suitable for a static mixing tip, comprising:
- a base;
- a sealing lip in the form of a protruding ridge or rim or strip around a circumference of the base, the sealing lip at least one opening in a radial orientation through the sealing lip configured to enable a gas to pass through the sealing lip.
