Abstract

The present disclosure is directed to bottles that are configured to undergo a controlled collapse in response to pressure being placed on the front and rear walls manually by a user, vacuum forces acting inside the bottle during a tube feeding process, or both. The bottles include a rigid hanging element that is molded into an access channel provided on the base of the bottle, such that the top and sides of the hanging element are fixedly connected with a surface of the container. Due to the presence of the hanging element, the bottle includes hinge lines focus the collapse in the central area of the bottle between the hanging element and the shoulder of the bottle. Accordingly, the present bottles provide both a rigid hanging element and walls that collapse in a controlled manner.

First claim

1 . A collapsible bottle comprising:
a base; a neck that defines an opening; a front wall; a rear wall; left and right side walls, each of the left and right side walls comprising
a rounded shoulder region that transitions to the neck,
a lower transition region that transitions into the base, and
a central region positioned between the rounded shoulder region and the lower transition region, the central region comprising a first panel and a second panel, the first and second panels being divided by a substantially vertical central hinge,
the first panel being divided from the front wall by a front hinge, and
the second panel being divided from the rear wall by a rear hinge;
wherein, when pressure is placed on the front and rear walls of the bottle, the front hinge line flexes inward, the rear hinge line flexes inward, and the central hinge flexes outward, such that the front and rear walls collapse toward one another with the central hinge being pushed outward away from the front and rear walls.

2 . The collapsible bottle of claim 1 , wherein the first panel is angled inward from the central hinge toward the front hinge and the second panel is angled inward from the central hinge toward the rear hinge.

3 . The collapsible bottle of claim 2 , wherein the angle formed between the first and second panels by the central hinge is between about 140 degrees and about 175 degrees, alternatively between about 145 degrees and about 170 degrees, alternatively between about 150 degrees and about 170 degrees.

4 . The collapsible bottle of claim 2 , wherein the center hinge fades toward the top of the central region such that each of the left and right side walls has a curved cross-section adjacent the rounded shoulder region.

5 . The collapsible bottle of claim 2 , wherein each of the front hinge and the rear hinge comprises an outward-projecting rib.

6 . The collapsible bottle of claim 5 , wherein the rib of the front hinge comprises an apex, a convex portion that transitions from the apex into the front wall, and a concave portion that transitions from the apex into the first panel; and
the rib of the rear hinge comprises an apex, a convex portion that transitions from the apex into the rear wall, and a concave portion that transitions from the apex into the second panel.

7 . The collapsible bottle of claim 6 , wherein each of the front and rear hinges has
(a) an outer curvature between about 135 degrees and about 165 degrees, optionally between about 140 degrees and about 160 degrees; (b) an inner curvature between about 140 degrees and about 180 degrees, alternatively between about 145 degrees and about 175 degrees; or (c) both a and b.

8 . The collapsible bottle of claim 6 , wherein the central, front, and rear hinges each fades toward the top of the central region such that each of the left and right side walls has a continuously curved cross-section adjacent the rounded shoulder region.

9 . The collapsible bottle of claim 1 , wherein each of the front and rear walls has an upper arched region.

10 . The collapsible bottle of claim 1 , wherein the bottle comprises a hanging element configured for the bottle to be suspended in an upside-down orientation.

11 . The collapsible bottle of claim 10 , wherein the hanging element comprises a tab having a hanging aperture, optionally a circular hanging aperture.

12 . The collapsible bottle of claim 11 , wherein the tab is positioned in an access channel that spans between the front and rear wall.

13 . The collapsible bottle of claim 12 , wherein the access channel extends upward from the base, dividing the base of the bottle into independent right and left portions, wherein the upper edge of the tab, the right edge of the tab, and the left edge of the tab are each integrally connected with a surface that defines the access opening.

14 . The collapsible bottle of claim 13 , wherein a lower edge of the tab is positioned upward of a standing surface of the base.

15 . The collapsible bottle of claim 13 , wherein the access channel has a first width at the front and rear walls and a second width at the tab, the first width being greater than the second width.

16 . The collapsible bottle of claim 15 , wherein the first width is at between 120% and 150% greater than the second width.

17 . The collapsible bottle of claim 1 , wherein the bottle has a tilt angle of at least 12 degrees, optionally at least 15 degrees, optionally at least 17 degrees.

18 . The collapsible bottle of claim 1 , wherein the base of the bottle does not deform during the collapse.

19 . The collapsible bottle of claim 1 , wherein the bottle is configured to collapse when emptied through a vented cap at a rate of (i) 300 mL/hr or (ii) both 150 mL/hr and 300 mL/hr.

20 . The collapsible bottle of claim 1 , wherein the bottle is configured to not collapse when emptied through a vented cap at a rate of (i) 150 mL/hr or (ii) both 150 mL/hr and 300 mL/hr.
