管子挤压装置

The consistency of the contents of a tube or sachet is fundamental to its ease of removal from the packaging when required. Many ready made convenience sauces and condiments can be found in sachet portions for quick and easy use. Similarly, many personal care creams and toothpastes are packaged in tubes for quick and easy removal and application whilst providing an ideal solution for long-term storage until all of the contents have been used. The removal of the contents relies upon the consumer squeezing the packaging. Assuming the orifice size remains constant, the force to squeeze the packaging depends largely on the consistency of the e.g. paste/cream. A new device (the Sachet/Tube Extrusion Rig) has been developed which allows the positioning of the end of a sachet or tube between two rollers. The packaging end is clamped with a grip which pulls the tube upwards through the rollers when the test is commenced and hence the contents of the sachet or tube are forced to extruded out of the orifice. The higher the force obtained during this test the more difficult a consumer would find to squeeze out their required amount.
