Abstract

A flexible pouch with a tube spout fitment and removable cap. The flexible pouch has a panel with an aperture and a tube spout fitment that extends through the aperture. The tube spout fitment has a first circumferential ridge with a first diameter and a second circumferential ridge with a second diameter. Also, the second diameter is larger than the first diameter. A dispensing cap is attached to the tube spout fitment. The dispensing cap has a first temporary snap position fitting over the first circumferential ridge of the tube spout fitment and a second permanent snap position fitting over the second circumferential ridge. In this manner, the dispensing cap can be temporarily attached to the pouch during storage, shipping and the like, removed prior to filling the flexible pouch with product, and then permanently attached after the pouch has been filled with product.

First claim

I claim:

1. A process for filling a flexible pouch with a product, the process comprising:
providing the flexible pouch, the flexible pouch having:
a panel with an aperture; and
a spout fitment extending through said aperture, the spout fitment having a base sealed to the panel and a distal end spaced apart from the base;
the spout fitment also having a first circumferential ridge with a first diameter proximate the distal end and a second circumferential ridge with a second diameter proximate the base, the second diameter being larger than the first diameter; and
a dispensing cap having an opening for product to flow through, the dispensing cap having a first temporary snap position fitting over the first circumferential ridge and a second permanent snap position fitting over the second circumferential ridge, the dispensing cap attached to the spout fitment over the first circumferential ridge in the first temporary snap position;

removing the dispensing cap in the first temporary snap position from the spot fitment;
filling the flexible pouch with the product through the spout fitment; and
re-attaching the dispensing cap onto the spout fitment such that an internal ridge of the dispensing cap is over the second circumferential ridge in the second permanent snap position, the dispensing cap in the second permanent snap position being permanently attached to the spout fitment and providing opening and closing of the flexible pouch for the product to flow from the flexible pouch and through the dispensing cap when the dispensing cap is in an open position and not flow from the flexible pouch when the dispensing cap is in a closed position.

2. The process of claim 1 , further including storing the flexible pouch with the dispensing cap in the first temporary snap position for a predetermined amount of time before removing the dispensing cap, filling the flexible pouch with the product through the spout fitment with the dispensing cap removed, re-attaching the dispensing cap onto the spout fitment in the second permanent snap position, the dispensing cap in the second permanent snap position providing the opening of the flexible pouch for the product to flow from the pouch and through the dispensing cap.

3. The process of claim 1 , further including shipping the flexible pouch with the dispensing cap in the first temporary snap position from one location to another location before removing the dispensing cap, filling the flexible pouch with the product through the spout fitment with the dispensing cap removed and re-attaching the dispensing cap onto the spout fitment in the second permanent snap position, the dispensing cap in the permanent snap position providing the opening of the flexible pouch for the product to flow from the pouch and through the dispensing cap.

4. The process of claim 1 , wherein the dispensing cap has an internal ridge, the internal ridge having the first temporary snap position fitting over the first circumferential ridge and the second permanent snap position fitting over the second circumferential ridge.

5. The process of claim 4 , wherein the internal ridge is attached to the spout fitment over the first circumferential ridge in the first temporary snap position.

6. The process of claim 1 , wherein the dispensing cap comprises a turn tab for moving the dispensing cap between the open position and the closed position.

7. A process for filling a flexible pouch with a product, the process comprising:
mounting a fitment to a portion of the flexible pouch;
mounting a dispensing cap in a first temporary position onto the fitment for transporting of the pouch, the dispensing cap having an opening for product to flow through;
removing the dispensing cap from the fitment;
filling the flexible pouch with a product through the fitment; and
replacing the dispensing cap onto the fitment in a second permanent position and engaging a lock portion of the fitment, the dispensing cap in the second permanent snap position being permanently attached to the spout fitment and providing opening and closing of the flexible pouch for the product to flow from the pouch and through the dispensing cap when the dispensing cap is in an open position and not flow from the flexible pouch when the dispensing cap is in a closed position.

8. The process of claim 7 , wherein the fitment has a first circumferential ridge with a first diameter proximate a distal end of the fitment and a second circumferential ridge with a second diameter proximate a base of the fitment, the second diameter being larger than the first diameter.

9. The process of claim 8 , wherein the dispensing cap is fitting over the first circumferential ridge while in the first temporary position and is fitting over the second circumferential ridge while in the second permanent position.

10. The process of claim 7 , wherein the dispensing cap comprises a turn tab for moving the dispensing cap between the open position and the closed position.
