ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention concerns packaging. It is more particularly concerned with parallelepiped-shaped packages or boxes for products such as bottles, but also prismatic and even cylindrical packages and boxes.
2. Description of the Prior Art
The present invention consists in a simple and economical new package offering technical and commercial advantages over existing products.
SUMMARY OF THE INVENTION
The present invention consists in a package comprising a first wall forming a blank of the package adapted to be folded to produce a three-dimensional package, and a second wall welded or glued to the surface of at least one inside panel or face of the first wall of the package to create a double wall on that face to define a peripheral container.
Accordingly, each side panel and the bottom panel and the lid panel of the package may have the double-wall structure forming a peripheral container into which an associated product can be loaded or inserted. This advantageously enables the packaging and marketing or distribution of samples of a number of other products in addition to the main product which is purchased by the consumer.
It is also clear that the peripheral containers, once filled and closed, advantageously protect the main product.
Providing the peripheral containers on an inside panel or face of the package means that the exterior appearance of the main packaging does not need to be modified.
In a preferred embodiment, the second wall is fixed to the first wall to create a sealed area able to receive fluid products.
One or more cavities are thus provided, defined by fillable double wall structures, also referred to as peripheral containers.
Accordingly, the package is easy to use and low in cost because it requires only cutting or blanking out and heat-welding or gluing operations.
This is particularly advantageous in the cosmetics field in particular, since means for carrying out these steps are readily available.
In a preferred embodiment of the invention the second wall is made of a flexible material, preferably a plastics material. It can, alternatively, be made of metal, cardboard or multilayer composite materials.
In a preferred embodiment the peripheral containers each form one panel of the package which can be separated from other panels when the package has been opened. Accordingly, at least one peripheral container is separated from other panels or peripheral containers to obtain a separate sachet or packet containing the auxiliary product or sample, which is the equivalent of taking apart the original package.
In one particular embodiment, the bending lines in the outside wall along which it is bent to form the main package include lines of perforations or weakness to enable the peripheral containers constituting the panels of the initial package to be separated.
In one embodiment the bending lines are adapted to severe or tear along a weakened line of the sheet material.
This feature takes advantage of a fact that merely by folding the package into its parallelepiped or prismatic shape, weakened lines are formed at edges in the sheet material defining the panels of the package along which it is easy to tear the sheet material.
In one embodiment the package includes on the inside wall peripheral container opening starter means to facilitate opening of the peripheral containers and access the auxiliary products therein.
In a preferred embodiment the package includes a coating on the inside surface of one first wall compatible with and impervious to liquid, solid or gaseous auxiliary products, to be contained in the double-walled structures.This ensures any damage to the outer wall of the main package by the sample(s) in the peripheral wall enclosure(s).
The invention is also directed to a method of manufacturing packaging adapted to contain a main product and one or more auxiliary products, including the following operations:
cutting out a blank forming a first or outside wall of a package from semi-rigid sheet materials, the blank incorporating folding lines,
cutting out a blank forming a second or inside wall from a flexible sheet material,
assembling the inside wall to the outside wall along at least one assembly line to form the contour of at least one peripheral container,
filling and then sealing the at least one of the peripheral container, and
bending the resulting assembly of the finished second walls to form the packaging for the main product.
The invention is also directed to a method of packaging a main product comprising an operation of forming the package as set out hereinabove and operations of loading an auxiliary product into at least one peripheral container, closing the at least one peripheral container once filled and bending the walls along the bending lines to form a box for the main product.
The following description and drawings show clearly the aims and advantages of the invention. It is clear that the description is given by way of example only and is not limiting on the invention.
