Abstract

The present disclosure provides a device. In an embodiment, a device for dispensing a fluid under pressure is provided and includes:
(A) a flexible container comprising four panels, each panel formed from a flexible multilayer film composed of one or more polymeric materials, the four panels forming
(i) a body, and (ii) a neck;
(B) a fitment comprising a top portion and a base, the base composed of a polymeric material, the base sealed in the neck; (C) a sleeve bag on valve assembly (SBoV) comprising
(i) a valve housing, (ii) a core tube attached to the valve housing, (iii) a bag around the core tube, the bag attached to the valve housing, (iv) a sleeve surrounding the bag and the core tube, and (v) a valve seat;
(D) the SBoV inserted through the fitment and located in the body; and (E) the valve seat attached to the fitment.

First claim

The invention claimed is:

1. A device for dispensing a fluid under pressure comprising:
(A) a flexible container comprising four panels, each panel formed from a flexible multilayer film composed of one or more polymeric materials, the four panels forming
(i) a body, and
(ii) a neck;

(B) a fitment comprising a top portion and a base, the base composed of a polymeric material, the base sealed in the neck;
(C) a sleeve bag on valve assembly (SBoV) comprising
(i) a valve housing,
(ii) a core tube attached to the valve housing,
(iii) a bag around the core tube, the bag attached to the valve housing,
(iv) a sleeve surrounding the bag and the core tube, and
(v) a valve seat;

(D) the SBoV inserted through the fitment and located in the body; and
(E) the valve seat attached to the fitment.

2. The device of claim 1 wherein the flexible container is a large volume flexible container.

3. The device of claim 1 wherein the flexible container comprises a front panel, a back panel, a first gusset panel, a second gusset panel, and a bottom segment; and
the panels and the bottom segment support the flexible container in an upright position when the bag contains a fluid composition for dispensing.

4. The device of claim 1 wherein the flexible container comprises a plurality of peripheral heat seals.

5. The device of claim 1 wherein the flexible container has a length (L) and a width (Wi), and the flexible container has a L:Wi ratio from 1.0 to 5.0.

6. The device of claim 1 wherein the bag has an expanded volume from 0.5 L to 30 L.

7. The device of claim 1 wherein the sleeve has an unexpanded thickness from 3.0 mm to 20.0 mm and the sleeve, at 400% elongation, has a tensile modulus of at least 20 MPa.

8. The device of claim 1 wherein the bag has an expanded volume from 0.5 L to 30.0 L, and the sleeve has an unexpanded thickness from 3.0 mm to 20.0 mm.

9. The device of claim 1 wherein the fitment base has a circular cross section with a diameter (d) and a wall thickness (WT), wherein the d/WT ratio (in mm) is from 5 to 450.

10. The device of claim 1 wherein the flexible container comprises at least one handle.

11. The device of claim 1 comprising a retaining ring for securing the valve seat to the fitment.

12. The device of claim 11 wherein the valve seat is sandwiched within a threaded engagement between the retaining ring and the fitment.

13. The device of claim 11 wherein the valve seat is sandwiched within a snap-on engagement between the retaining ring and the fitment.

14. The device of claim 1 wherein the bag contains a fluid composition.

15. The device of claim 1 wherein the volume amount of the fluid composition present in the bag is from 70% to 95% the volume of the flexible container.

16. The device of claim 1 where the flexible multilayer film has a thickness from 100 μm to 400 μm.

17. The device of claim 1 wherein the fitment base has a wall thickness from 0.15 mm to 2.0 mm.

18. The device of claim 1 wherein the bag is refillable.
