Abstract
A medicament container including at least one sidewall and an extension is provided. The extension may be rigid in comparison to sidewalls that form the volume of the container. The extension may extend substantially into the volume of the container to a central region of the container. The container may include one or more ribs formed in the sidewalls to provide structural rigidity to the sidewalls.
Claims27
A medicament container comprising:
- a sidewall at least partially defining an interior volume of the medicament container;
- a spout for outflow of medicament from the interior volume of the medicament container, the spout being coupled to the sidewall;
- and
- an extension coupled to the spout and having a pair of opposing faces, the extension being disposed inside the interior volume of the medicament container and including a passage in fluid communication with the interior volume of the medicament container and the spout, the sidewall having a greater flexibility than the extension such that the medicament container has a collapsed state when empty and an expanded state when full,
- wherein the sidewall is configured to move as medicament flows out of the interior volume of the medicament container through the spout,
- wherein the extension has a first end adjacent the spout and a second end opposite the first end, the opposing faces of the extension tapering to an edge at the second end, and
- wherein a height of the extension measured from the first end to the second end along a central axis of the spout is at least one-fourth of a sidewall height, the sidewall height being measured along a dimension parallel to the central axis of the spout when the medicament container is in the expanded state.

- wherein the sidewall is configured to move as medicament flows out of the interior volume of the medicament container through the spout,
- wherein the extension comprises a first portion having a first end and a second portion having a second end, the first end being closer to the spout than the second end is to the spout, the passage having an opening at the second end, and
- wherein a cross-sectional area of the extension measured normal to a central axis of the spout is greater at the first portion than at the second portion, the cross-sectional area of the second portion decreasing along the central axis moving away from the spout such that the extension tapers towards the second end, the central axis being parallel to an outflow direction through the spout.
