The Receiving Bottle's Neck
A wide spout pointed at a narrow bottle neck can turn a simple refill into an unnecessarily messy task. The pouch may hold the correct quantity and close securely, yet its dispensing outlet may be poorly suited to the container the customer is trying to fill.
For refill products, the receiving container should influence the spout before the pouch's final shape is established.
Custom Spouted Pouches combine a flexible pouch body with an attached dispensing fitment and a compatible cap. They are used for liquids, concentrates, sauces, gels and other products that benefit from directed pouring or repeated dispensing.
Unlike an ordinary tear-open pouch, the spout establishes a permanent outlet.
Its internal diameter, external dimensions and position influence how the product leaves the package. These decisions also affect filling equipment, closure selection and the surrounding pouch construction.
The Receiving Opening
A refill intended for an existing bottle needs an outlet appropriate for that bottle's opening.
The spout should support controlled transfer without requiring the customer to hold the pouch in an awkward position.
For a narrow receiving container, a smaller outlet may improve pouring control. However, a very small outlet can restrict the flow of thicker products.
The appropriate fitment depends on the actual formulation and intended transfer method.
The receiving bottle's neck also affects how close the pouch can be positioned during pouring. A large cap assembly or projecting pouch corner may prevent the outlet from approaching the opening comfortably.
These dimensions should be considered together rather than selecting the fitment solely by its nominal diameter.
Pouring Versus Squeezing
A spout intended for gravity pouring may need different characteristics from one used with a squeezable pouch.
A free-flowing liquid can leave the package as it is tilted. A thicker product may require pressure on the flexible body.
For squeeze dispensing, the film construction and pouch shape must allow the intended deformation without compromising the seals or fitment attachment.
The customer should also be able to control the amount dispensed.
A large opening may be suitable for transferring an entire refill into a bottle but less appropriate for dispensing a small amount directly into the hand.
The intended use determines the outlet.
