BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a package for a series of products, of the type comprising a pliant wrapper, especially of elongate general shape, including a folded and sealed sheet.
Known packages of this type are especially intended for prepackaged products which may, for example, be ailments, such as strips of chewing gum, cheese slices, biscuits or bars of chocolate, or else chip cards. The wrapper contains these products and may be constituted by a rolled-up or folded sheet, for example made of paper or of a complex produced, for example, by the association of a plastic film, of paper and of aluminium (or by the combination of two of these); this sheet surrounds and then envelops a stack of the said products in order to form a cylinder held together by adhesively bonding one longitudinal edge of the sheet to the opposite longitudinal edge; the ends of the cylinder are held in position, folded, by sealing, for example by adhesive bonding, in order for one to form the end wall and the other the lid of the wrapper.
In order to open a package, the lid of the wrapper is, for example, torn and unfolded; when a tear strip is provided for this purpose in proximity to the lid over a circumference of the cylinder of the wrapper, this strip is preferably torn and the lid completely and permanently removed.
Such a package is very economical for commonly consumed products and highly advantageous since it allows them to be preserved grouped together in the wrapper and available, at any moment, for dispensing and consumption.
However, as soon as the wrapper of a package of this type has been opened, it can no longer be closed up again in a secure manner and/or it is permanently without a lid; this wrapper therefore runs the risk, at any moment, of allowing the remaining products that it contains to escape, which represents a serious drawback. This is particularly annoying when the package whose wrapper is already opened is left in the pocket of an article of clothing, in a bag or a case, or else in the glove compartment of a vehicle. The remaining products that it contains may then become dispersed with other objects.
SUMMARY OF THE INVENTION
The object of the present invention is to preserve the integrity of the contents of the wrapper of the package after the wrapper has been opened, including after taking out one or more products from the open wrapper, while at the same time preserving the economical and advantageous character of this type of package.
To this end, the subject of the invention is a package of the aforementioned type, characterized in that a means of temporary adhesion of the products to be packaged is interposed between the wrapper and each of the products.
This package may include one or more of the following characteristics: that is aligned with a sealed area of the wrapper; closed by a lid, especially one that cannot be closed again after opening, the other end closed by folding and sealing, serving as the end wall for the wrapper, the means of temporary adhesion of the products to be packaged is interposed between the end wall of the wrapper and the adjacent end of each of the products; elongate shape; adheres to the wrapper; pressure-activable cold-setting adhesive type; type.
The subject of the invention is also a method of producing a package as defined hereinabove.
In a first embodiment, this method, of the type comprising: sheet; and sealing, especially by adhesive bonding, the said sheet thus closing up this wrapper at least partially, wrapper, a step (c) of depositing a means of temporary adhesion on that face of the said sheet intended to constitute the inside face of the wrapper, and in that, during the sealing step (b), the means of adhesion is activated at the same time as the sealing of the wrapper.
When the formation of the wrapper at step (b) includes a step of sealing, especially by adhesive bonding, the opposite edges of the said sheet closing up the circumference of the wrapper blank, and a step of folding and sealing, especially by adhesive b
