Definitions

• the invention relates to a packaging of the type comprising a flexible internal pocket and a rigid external envelope. It also relates to a process for producing such packaging.
• Packages of the type already known include an internal plastic bag intended to receive a content to be packaged and provided at the point of an opening with a removable or displaceable closure system and, surrounding this pocket, an external envelope produced from a cardboard or equivalent form, cut, folded and secured to itself.
• packages such as those conventionally used for grouping a few unit packages of beer, soft drinks, dairy products, etc.
• the outer envelope has the form of a tubular jacket. It is relatively flexible and deformable, by nature, while being stretched over the individual packaging grouped together. These packages are themselves rigid and allow the tension of the external envelope ensuring the desired maintenance.
• Packages are also known which consist of flexible plastic bags, possibly provided with a transverse bottom but without an external envelope.
• Such packaging has the disadvantage of having a certain fragility, of being inconvenient to store, to present, of only allowing the position of decorative, commercial, advertising mentions with difficulty.
• the invention aims to propose a packaging of the type comprising a flexible and deformable internal pocket intended to receive a content to be packaged and an external envelope surrounding the pocket. More specifically, the invention aims to reduce the costs of manufacturing such packaging, whether it be the materials used or the packaging process itself.
• the packaging can be easily dissociated, after use, into two different parts, one formed by the pocket and the other formed by the external envelope. This dissociation allows a specific treatment of these two parts of different nature in accordance with the requirements of ecology.
• Another goal is to provide some tension permanent pocket to avoid any retention of the contents in folds forming a trap.
• Another aim is that the contents of the bag can be used in a fragmented manner.
• Another object is also to avoid maneuvers for extracting the closure, such as those known for crates. Another goal is that the packaging has large and rewarding surfaces for the position of decorations, commercial or advertising mentions. Another object is also to be able to give the packaging a shape reminiscent of that of a container such as a container of injected-blown plastic. Another object is that the packaging can be handled easily and that its use is practical. Finally, another aim is to allow the pocket to be seen and therefore the degree of filling thereof with the contents.
• packaging of the type comprising:
• a flexible and deformable internal pocket intended to receive a content to be packaged and provided at the point of an opening with a base forming a neck and with which is associated a removable or displaceable closure cap,
• the outer envelope comprises towards its top, opposite a bottom situated transversely to the main axis of the packaging, one or more cutouts or indentations of imprisonment of the base and, in the vicinity of these, a handling handle;
• the means for securing the external envelope on itself and the pocket on the external envelope are removable or destructible so as to cease to be effective under the action of sufficient manual constraints to destroy the packaging thus allowing its dissociation into two distinct parts, namely the pocket and the envelope.
