Definitions
- a peristaltic pump 10 is shown in block form, which includes a motor 12, a shaft 14, and head (or heads) 16. Head or heads 16 engage a molded tube 18. The head or heads 16 squeeze the tube 18 (against a back or opposing head or heads) and push fluid in the desired direction.
- the fluid comes from a supply 20, which may be a bag of fluid, such as a plastic bag used in a bag- in-box beverage system, or a pharmaceutical bag, used for pharmaceuticals or other fluids.
- the supply 20 generally includes a supply fitment 22 that is coupled to a tube fitment 24 through any of several known approaches.
- tube fitments cause inlet pump flow restrictions, as it is difficult to stretch an extruded tube over a wide tube fitment.
- the flow restriction issue is particularly important in pumping relatively high viscosity liquids, such as, without limitation, orange juice concentrate, wherein inlet flow restrictions can significantly affect desired flow rates.
- the expanded diameter section 32 may be formed in other processes as well, such as, without limitation, with an expansion mandrel inserted into the tube 18.
- the tube 18 may be ejected from the mold system by any suitable approach.
- One approach is to inject a gas through a gas port 54, which allows gas (such as, without limitation, air) to flow through the end of the core 40 to eject the molded tube 18.
- FIGURES 5 and 6 are cross sectional views of another embodiment of a system for molding a tube 18 according to the teachings of present invention.
- the tube 18 is molded around a fitment 24.
- FIGURE 5 shows the molding system in the closed position
- FIGURE 6 illustrates it in the open position, with the tube 18 ready to be ejected.
- the fitment 24 may be of any suitable material, including, without limitation, plastic or metal.
