Abstract

The present disclosure provides a container for dispensing a liquid from the container. The container includes a flexible body having a closed top and an open bottom and a base attached to the open bottom of the body. The body and base define a chamber for holding a liquid. The base includes a floor and a peripheral rim extending below the floor. A nozzle extends from the floor. A closure slidingly engages with the nozzle. The closure includes a panel-cap having an aperture through which the liquid is dispensed.

First claim

The invention claimed is:

1. A container comprising:
a flexible body having a closed top and an open bottom, the body defining a chamber for holding a liquid, the flexible body constructed from two multilayer flexible films, each multilayer film having an innermost seal layer and an outermost print layer;
a base attached to the open bottom of the body, the base comprising a floor and a peripheral rim extending below the floor, a nozzle centrally located on the floor and extending from the floor, the nozzle surrounded by the peripheral rim;
the multilayer films sealed along a peripheral seal extending from a first side of the base, along an upper portion of the body, and to a second side of the base;
a closure slidingly engaged with the nozzle, the closure comprising a panel-cap having an aperture through which the liquid is dispensed, the panel-cap having a bottom surface with a length and a width, and the panel-cap length is greater than the panel-cap width; and
the container is a hinge-free tottle container comprising from 90 wt % to 100 wt % ethylene-based polymer.

2. The container of claim 1 wherein the panel-cap has an area that is at least 15% of a footprint area defined by the peripheral rim.

3. The container of claim 1 wherein the closure has a closed position wherein a tip of the nozzle matingly engages with the aperture and blocks fluid flow through the aperture.

4. The container of claim 1 wherein the closure has an open position wherein a gap is present between a tip of the nozzle and the aperture, permitting fluid flow through the aperture.

5. The container of claim 1 wherein the body comprises an upper heat seal portion, the upper heat seal portion comprising a hole for hanging the container from a support structure.

6. The container of claim 1 wherein the peripheral rim defines a footprint having an eye-shape; and the panel-cap has an eye-shape that matches the eye-shape of the peripheral rim footprint.

7. The container of claim 1 wherein a top surface of the panel-cap defines a fingerhold for a user.

8. The container of claim 1 wherein a height of the container is from 15 times to 30 times greater than a height of the base.

9. The container of claim 1 wherein the bottom surface of the panel-cap is coplanar with a bottom surface of the rim when the closure is in the closed position.

10. The container of claim 1 wherein the closure has an open position wherein the panel-cap extends beyond the peripheral rim and placing the base on a support surface moves the closure to a closed position.

11. The container of claim 1 wherein the body has a surface roughness, Ra, from 0.2 to 0.8.

12. The container of claim 1 wherein the panel-cap has a thickness from 1.0 mm to 3.0 mm.

13. The container of claim 1 wherein each multilayer film comprises an innermost layer comprising linear low density polyethylene and an outermost print layer comprising a polyester.

14. The container of claim 1 wherein each multilayer film has a thickness from 25 microns to 125 microns.

15. The container of claim 1 wherein the cross-section of the body is greater than the cross-section of the base.
