CONTAINER THAT IS INVERTED ON ITS PROPERTY WHEN EMPTYING, WITHOUT CONNECTION IN THE NEXT TO ITS MEDIUM POINT TO AN EXTERIOR PACKAGING, TYPE BOTTLE OF SPREAD

摘要

An inner receptacle is provided which is adapted to be used with a resilient squeeze bottle. The inner receptacle includes a flexible bag and includes a mechanism for causing the flexible bag to invert upon itself about its midpoint without requiring attachment of the inner receptacle to the squeeze bottle. The inversion enables substantially all of the product within the receptacle to be dispensed. One preferred mechanism for causing inversion is a support frame which resembles a bird cage. This support frame may be located inside or outside the top half of the flexible bag. Such inner receptacles offer special advantages when utilized with reusable squeeze bottles. The reusable squeeze bottles may be oval and include an opening at the top which accommodates the dispensing opening of the inner receptacle and an opening at the bottom and through which the entire inner receptacle may pass. An end plate is utilized to seal the bottom end of the squeeze bottle. One preferred squeeze bottle includes an inner sleeve and an outer sleeve which enables replacement of the inner receptacle while manipulating only one closure element.
