Abstract

A package to facilitate the use of squeeze bottles and other dispensers, particularly in the food service industry. The invention is directed to, in particular, a combined bottle pouch and food product, which includes a pouch having a peelable primary seal area and lines of weakness for ready opening of the pouch. The lines of weakness, or other area(s) of weakness, can be formed in a flap or membrane, which together with the area of weakness forms a secondary seal for the pouch. The flap or membrane is preferably sealed to the walls of the pouch. Preferably, the combined pouch and food product also includes a bottle closure.
The product of the invention facilitates the use of squeeze bottles for products such as mayonnaise and other dressings in food service by permitting sale of a combined bottle pouch and food product to the busy eating establishment. The eating establishment can simply insert the pouch into the squeeze bottle or other dispenser, open the primary seal on the pouch, and fasten a bottle closure onto the squeeze bottle. The squeeze bottle is then ready to dispense the product.
