Title:
DELIVERY CONTAINER
Document Type and Number:
WIPO Patent Application WO/2001/038194
Kind Code:
A1
Abstract:
A delivery container using a laminated bottle having a peeling inner layer capable of being manufactured without increasing the number of processes, eliminating the need for providing a valve to close vent ports by properly controlling the volume of air flowing through the vent ports to a clearance between the inner and outer layers, simplifying a structure, and reducing a cost, wherein the vent ports provided only in the outer layer of the laminated bottle are kept open at all times, and the vent ports are formed of those holes smaller in opening area than that of the delivery port so that, when an outer layer body part is squeezed so as to pressurize the air present between the outer and inner layers, the liquid in the bottle can be delivered from a delivery port of a cap by an air pressure pressing the inner layer from the surrounding.
