Abstract

An envelope structure with a stiffening device for the transformation into a box for containing different articles, obtained from a plane outlined shaped, provided with ribbing for folding, so as to turn into a box of parallelepiped, trapezoidal or any other shape, stiffened and therefore made functional by the inward folding of elements called tabs which, with their tension, allow to keep open lateral folding of said envelope; a front flap pliable into a housing pocket further strengthens the obtained container which may also receive articles of considerable weight, and for closing the obtained structure.

Description

AN ENVELOPE STRUCTURE WITH A STIFFENING DEVICE

The present invention concerns an envelope structure with a stiffening device for transforming it into a box for containing different articles.

Envelopes out of paper, plastified paper or out of other materials are already well known and they are widely used for containing dresses, shoes, food and all other possible purchases of the modern market.

The aim of the present invention consists in realizing a structure of an envelope of new and original conception that may be transformed, due to its special features, into a rigid box of considerable functionality and aesthetic impact.

The aim set forth is reached by means of an envelope structure obtained from a plane outlined shape, provided with ribbing for folding, so as to turn into a box of parallelepiped, trapezoidal or any other shape, stiffened and therefore made functional by the inward folding of elements called tabs which, with their tension, allow to keep open lateral foldings of said envelope. A flirtlier feature of the present invention consists of tl e presence of a pliable front flap and of a corresponding pocket into which said flap is housed so as to strengthen the obtained container which may receive also articles of considerable weight, and for closing the obtained structure.

The advantage of tl e transformation of a soft envelope into a rigid box that may contain also cumbersome and heavy articles, are evident.

The present invention will be described more in detail hereinbelow relating to tlie enclosed drawings in which some embodiments are shown.

Figure 1 shows a plane shaped structure according to tlie present invention provided with ribbing, out of paper, plastified paper or other suitable material, from which, following to folding and gluing, shown in figure 2, tl e finally resulting box is obtained, shown in an axonometric transparent view in figure 3.

Figures 4 and 5 show a variant of the structure according to tlie present invention with a double handle with two small snares, internally blocked by knots.

Figures 6 and 7 show a variant with a double handle with only one small snare. Figure 8 shows a box without any handle.

Figure 9 shows tlie upper part of a variant of a plane shape, with a closing tongue, used in the shaped and closed box of figure 10, and in double use in figure 11.

Figures 12 and 13 show a closing variant of tlie front flap, respectively with one or two bows.

In a furtlier variant, figures 14 and 15 a single or double lozenge lock.

Figure 16 shows three possible variants of tl e shape of tl e front flap.

Figure 17 shows a structure provided with ribbons on tl e flap and on tl e front surface, for closing with a bow.

Figures 18 and 19 show two shape variants of the front flap.

The enclosed figures show an envelope structure according to tl e present invention with a stiffening device for transforming it into a box for different articles, obtained from a plane shape 1 out of paper, plastified paper or other suitable material, shaped and ribbed in such a way as to be folded and glued for forming a container box 2, comprising: a front flap 3, pliable inside a pocket 4 for obtaining tl e closing of the box; two lateral tabs 5, pliable inwardly so as to stiffen the bendings 6 of the folding; - a strengthening element 7 out of cardboard or plastic material or other material that may be inwardly or outwardly applied to an upper structure 8 for strengthening tlie handles with small snares 9 with bows 11, or of other kind.

The handle of the structure according to the present invention may be realized with a small cord or with a cotton or satin ribbon, or with a small pipe and straps out of plastic or twisted paper or leather or any other material that may be grasped, with variable thickness, dimension, length and colours; it may be internally kept or not with knots, adliesive paper or glue or in any other way suitable for tlie purpose.

The holes 10 on the reinforcing material 7, for passing the handle material, may be round or cut or of any other suitable shape and they may also have reinforcing eyelets or similar, our of metal or similar material.

In the variants shown in figures 10 and 11, the external tongue 12, shaped by tlie punch of the front flap 3 or applied separately, may receive tlie adliesive label of die user. The tongues for fixing said pocket 4 to said foldings may be glued or riveted or fixed in any other way.

For what concerns tl e variant shown in figures 12 and 13, tl e ribbon 13 may be out of cotton, satin, acrylic, paper, raffia, string or similar materials of any height, colour and length suitable, and tlie fastening may be performed with two or more ribbons or similar, generic or with a personalized wording, of variable thickness, width, length and colours, and may be applied by cutting or similar, fixed internally or in other way.

Furthermore, according to tlie variants shown in figures 14 and 15, tl e fastening of tl e structure according to tl e present invention may be obtained with one or two lozenges 14 of rigid paper material, fixed at the centre with metal - but not only - rivets 15, with diffeent measures and shapes: oval, round, square, as a lozenge and in any way suitable for the use, blocked internally but not only, in any way suitable for tl e purpose.

The closing flaps 16 may have angle shapes A and B or a round shape C, with the same functionality.

Finally, tlie fastening may be performed with ribbons 17, glued and liable with said flap 3, and with ribbons 18, bound to tl e structure for tl e realization of single or double bows. Relating to figures 18 and 19, the shape of the outer part may be smooth or punched with different mouldings or with a multiple grapliic image, aestlietically and functionally suitable for tl e purpose, and with a shape curved D or multi-lobed E.
