Abstract

A probe for dispensing a flowable material includes a body having a first end and a second and a passage extending therethrough. The probe has a first engagement portion configured to have a deformed state when the first end of the body is in contact with a dispensing component, and an undeformed state. The probe has a channel having a floor and two walls and is on the first engagement portion. The probe has a second engagement portion to frictionally fit within the dispensing component and to form a seal between the probe and the component. The probe has a locking groove to prevent movement of the probe relative to the dispensing component. In the undeformed state, the walls of the channel are spaced apart at a first distance, and in the deformed state, the walls are spaced apart at a second, smaller distance.

First claim

What is claimed:

1. A probe for dispensing a flowable material from a source, the probe comprising:
a body having a first end and a second end opposite the first end, the body defining a passage extending therethrough between the first end and the second end;
a first engagement portion configured to have an undeformed state and a deformed state, the first engagement portion being in the deformed state when the first end of the body is in contact with a dispensing component;
a channel having a floor and two walls opposite each other, the channel being disposed on the first engagement portion
a second engagement portion configured to frictionally fit within the dispensing component and to form a seal between the probe and the dispensing component; and
a locking groove configured to prevent movement of the probe relative to the dispensing component,
wherein when the first engagement portion is in the undeformed state, the two walls of the channel are spaced apart at a first distance, and when the first engagement portion is in the deformed state, the two walls are spaced apart at a second distance smaller than the first distance.

2. The probe of claim 1 , wherein the first end of the body is tapered.

3. The probe of claim 1 , further comprising a flange extending radially from the body.

4. The probe of claim 1 , further comprising a connection interface at the second end of the body, the connection interface being configured to engage with one or more dispensing components.

5. The probe of claim 1 , wherein the first engagement portion and the second engagement portion are separated by the locking groove.

6. The probe of claim 1 , further comprising a plurality of channels disposed radially around the first engagement portion, each channel of the plurality of channels extending between the first end of the body and the locking groove.

7. The probe of claim 1 , wherein the body defines a first wall thickness at the first engagement portion having the channel and a second wall thickness at the first engagement portion not having a channel, the first wall thickness being less than the second wall thickness.

8. The probe of claim 1 , wherein the body defines a third wall thickness of the second engagement portion, the third wall thickness being uniform along the entirety of the second engagement portion.

9. The probe of claim 1 , wherein the locking groove has a floor, a first wall disposed at a first angle relative to the floor, and a second wall disposed opposite the first wall and at a second angle relative to the floor, the first angle being larger than the second angle.

10. The probe of claim 1 , wherein the probe is a unitary piece and comprises plastic.

11. The probe of claim 1 , wherein the first engagement portion has a circular cross section when in the undeformed state and a non-circular cross section when in the deformed state.

12. The probe of claim 1 , wherein the second engagement portion is configured to create a fluid-tight seal when in contact with the dispensing component.

13. A method of connecting a probe to a dispensing component, the probe having a body with a first end and a second end opposite the first end and a passage extending therethrough, the probe further having a first engagement portion and a second engagement portion, the method comprises the steps of:
providing the dispensing component configured to receive the probe;
aligning the first end of the probe with the dispensing component;
moving the probe in a first direction towards the dispensing component;
contacting the dispensing component with the first engagement portion such that the first engagement portion deforms due to the contact with the dispensing component;
moving the probe in the first direction such that the second engagement portion contacts the dispensing component;
further moving the probe in the first direction such that a first locking bead on the dispensing component is moved into a locking groove defined on the probe; and
further moving the probe in the first direction such that the first locking bead is moved out of the locking groove and a second locking bead is moved into the locking groove.

14. The method of claim 13 , wherein the user applies a first amount of force to slidably contact the first engagement portion of the probe with the dispensing component and a second amount of force to slidably contact the second engagement portion of the probe, the first amount of force being less than the second amount of force.

15. The method of claim 13 , further comprising disconnecting the probe from the dispensing component such that the probe is not suitable to be re-connected to the dispensing component.
