Abstract

A dispensable substance container may include a printing substance dispensing nozzle including a first material. The dispensable substance container an elongate body, including a wall, including a second material encompassing a cavity to contain a dispensable substance, and an attachment portion to attach the elongate body to the printing substance dispensing nozzle; and a structurally compromised portion of the elongate body extending along a length of the elongate body, wherein the elongate body and the attachment portion are to be severed along the structurally compromised portion by a pushrod moveable through the cavity to expel the dispensable substance out the dispensing nozzle.

First claim

What is claimed:

1. A dispensable printing substance container, comprising:
a printing substance dispensing nozzle comprising a first material;
an elongate body, comprising:
a wall, comprising a second material encompassing a cavity to contain a dispensable substance, and
an attachment portion to attach the elongate body to the printing substance dispensing nozzle; and
a structurally compromised portion of the elongate body extending along a length of the elongate body, wherein the elongate body and the attachment portion are to be severed along the structurally compromised portion by a pushrod moveable through the cavity to expel the dispensable substance out the dispensing nozzle.

2. The dispensable printing substance container of claim 1 , wherein the first material and the second material are separately recyclable.

3. The dispensable printing substance container of claim 1 , wherein the second material comprises a pulp fiber.

4. The dispensable printing substance container of claim 3 , wherein a face of the elongate body facing into the cavity is coated with a barrier material.

5. The dispensable substance container of claim 1 , wherein the structurally compromised portion of the elongate body is a structurally weakened portion of the wall of the elongate body.

6. The dispensable substance container of claim 1 , wherein a non-structurally compromised portion of the elongate body has a greater shear strength than the structurally compromised portion of the elongate body.

7. A system, comprising:
a dispensable printing substance container, including:
a printing substance dispensing nozzle comprising a first material;
an elongate body, comprising:
a wall, comprising a second material encompassing a cavity to contain a dispensable substance,
an attachment portion to attach the elongate body to the printing substance dispensing nozzle, and
a structurally compromised portion of the elongate body extending along a length of the elongate body and through the attachment portion of the elongate body, wherein the elongate body and the attachment portion are severable along the structurally compromised portion by a movement of a pushrod through the cavity; and

a pushrod, comprising a third material, moveable along the length of the elongate body through the cavity to expel the dispensable substance out the dispensing nozzle.

8. The system of claim 7 , wherein the pushrod includes a projection off a central body of the pushrod, wherein the projection is extendable through the wall of the elongate body when the central body of the pushrod is seated within the cavity of the elongate body.

9. The system of claim 8 , wherein the movement of the pushrod includes a stroke from a first end of the elongate body distal the attachment portion to a second end of the elongate body proximate the attachment portion.

10. The system of claim 9 , wherein the projection includes a bladed portion position-able at the structurally compromised portion of the elongate body to split the elongate body, including the attachment portion, into a plurality of segments along the structurally compromised portion, releasing the attachment between the elongate body and the printing substance dispensing nozzle, during the stroke.

11. The system of claim 10 , wherein each of the plurality of segments of the split elongate body are separable from the printing substance dispensing nozzle to release the pushrod from the cavity.

12. A device, comprising:
a printing substance dispensing nozzle;
an elongate body comprising:
a wall encompassing a cavity to contain a dispensable printing substance,
an attachment portion to attach the elongate body to the printing substance dispensing nozzle;
a structurally compromised portion of the wall extending longitudinally along a length of the elongate body; and

a pushrod, including:
a central body of the pushrod, to seat within the cavity, moveable longitudinally through the length of the elongate body to expel the dispensable printing substance out the printing substance dispensing nozzle, and
a projection from the central body to separate the elongate body, the pushrod, and the printing substance dispensing nozzle by introducing a gap into the structurally compromised portion of the wall and the attachment portion when the central body is moved through the cavity in response to a force applied to a handle outside of the wall and connected to the central body through the gap.

13. The device of claim 12 , wherein the elongate body is split into a plurality of portions when the central body is pushed to a first end of the elongate body and the dispensable printing substance is transferred out of the cavity.

14. The device of claim 12 , wherein the attachment portion is split into a plurality of portions releasing the attachment between the elongate body and the printing substance dispensing nozzle when the central body is pushed to a first end of the elongate body and the dispensable printing substance is transferred out of the cavity.

15. The device of claim 12 , wherein the attachment portion comprises a lip on an exterior surface of the wall, opposite the cavity, to engage a retention ledge on an interior wall of the printing substance dispensing nozzle.
