Abstract
A dispenser (10) for dispensing flowable materials has a container (12) having an outer wall (16) and a membrane (34) collectively defining a first chamber (18) configured to contain a flowable material. The membrane (34) extends from the outer wall (16) at an angle. The membrane (34) has a thickness and a weld seam (40), and the weld seam (40) has a thickness less than the thickness of the membrane (34).
Claims29
A container assembly comprising:
- a first container having an outer wall and a first membrane collectively defining a first chamber configured to contain a first flowable material, the first membrane extending from the outer wall at an angle, the first membrane having a first weld seam;
- and
- a second container configured to hold a second flowable material, the second container having a second membrane having a second weld seam, wherein the second container is contained within the first chamber of the first container, wherein the second container is rupturable along the second weld seam and configured such that the second flowable material can mix with the first flowable material to form a mixture to be selectively dispensed from the container assembly.
A container assembly comprising:
- a first container having a first outer wall and a first membrane collectively defining a first chamber configured to contain a first flowable material, the first membrane having a first weld seam, the first weld seam having a thickness less than a thickness of the first membrane;
- and
- a second container having a second outer wall and a second membrane configured to hold a second flowable material, the second membrane having a second weld seam, the second weld seam having a thickness less than a thickness of the second membrane, wherein the second container is contained within the first chamber of the first container, wherein one of the first membrane and the second membrane extends from a respective outer wall at an angle to form a conical membrane, wherein the second container is rupturable along the second weld seam and configured such that the second flowable material can mix with the first flowable material to form a mixture to be selectively dispensed from the container assembly upon rupture of the first weld seam.
A membrane for a dispenser having a chamber containing a flowable material, the membrane comprising:
- a web of material configured to seal the chamber, the web of material being generally conically-shaped, the web having a thickness and a weld seam, the weld seam having a thickness less than the thickness of the web.
A dispenser for dispensing a flowable material, the dispenser comprising:
- a container having an outer wall and a membrane collectively defining a first chamber configured to contain a flowable material,
- the membrane extending from the outer wall at an acute angle, the membrane having thickness and a weld seam, the weld seam having a thickness less than the thickness of the membrane.
A one-piece dispenser for dispensing a flowable material, the dispenser comprising:
- a container having an outer wall and a membrane collectively defining a first chamber configured to contain a flowable material,
- the membrane being conically-shaped and the membrane extending from the outer wall, the membrane having thickness and a weld seam, the weld seam having a thickness less than the thickness of the membrane, wherein the container and membrane are integral with one another.
