Folding Box with Decorative Tab

Abstract

A re-closable folding box of cardboard with at least one closure is made available, which can be closed by machine without the need to glue the closing elements. The closure comprises a cover flap with a decorative tab, the inside surface of which comprises first retaining means, and second retaining means formed on a body panel. The second retaining means engages with the first retaining means in the closed state of the closure in such a way that the closure is held closed by the force of friction, wherein the decorative tab covers the first and second retaining means.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority based on German patent application DE 20 2008 002 483.8, filed Feb. 22, 2008.FIELD OF THE INVENTION[0002]The invention pertains to a re-closable folding box with an invisible closure without adhesive.BACKGROUND[0003]Folding boxes are playing an ever increasing role in the packaging area of high-value products such as creams and perfumes. So that the folding box can be brought into harmony with the claim to quality of the product in the package, ever stricter requirements are being imposed on the external appearance of the packaging. One of these requirements is to provide the closure of the re-closable folding box with an attractive decorative tab.[0004]Known folding boxes with a decorative tab use a rubber band, for example, to keep the box closed. This rubber band holds the decorative tab in such a way that the closure is not visible from the outside when the box is in the closed state. It is also possibl...

AI Technical Summary

Benefits of technology

[0007]It is an object of the present invention to provide an improved re-closable folding box with a decorative tab which satisfies the aesthetic requirements in question, which can be handled easily and quickly like a conventional folding box during assembly, and which does not need any additional closing means or gluing.

[0011]According to one aspect of the invention the second retaining means is formed as a tongue and the transition area between the edge of the body panel and the tongue comprises open areas, which enable the first retaining means to be guided along the tongue. This has the result that the tongue can be formed out of the cardboard blank by suitable provision of score lines on, and cuts in, the body panel, thus eliminating the need for additional elements. The cuts, that is, the lateral boundaries of the tongue, are preferably dimensioned in such a way that they are somewhat longer than the width of the retaining tab. In this way, the length of the engaging surface of the tongue can be adjusted to suit the width of the retaining tabs.

[0013]According to one aspect of the invention the blank of the inventive folding box consists of a single piece of material. Thus the folding box with decorative tab can be prefabricated by providing it with score lines, by cutting it to size, and by pre-gluing it in such a way that the packaging of the product and the closing of the folding box can be accomplished easily and at low cost by means of known packaging machines in the plant of the producer of the product.

Problems solved by technology

All of these known closure elements suffer from the disadvantage that, after the product has been introduced into the folding box package, an additional packaging step is required to attach them.

This prolongs the packaging process, increases the amount of material used, and thus leads to higher production costs.
