FR2612887A1 - Reversible postal envelope with hermetic closure - Google Patents

Abstract

The invention relates to a device making it possible to use a postal envelope for two postings and allowing the appearance for each one of these postings of only the address and stamps, the other address being hidden. In both cases the envelope is hermetically sealed </H0> It is composed of five main parts: a send panel 1, a median panel 2 and a return panel 3. The references 1 and 3 being provided with a closing flap 4 and 5, for the first posting 16, 18 and 5 are folded onto the panel 3 and the latter onto the panel 2, then the assembly which is glued by the glued margins 19, 20, 21. For the return, the panels 1 and 2 having been stripped from the margins 19, 20, 21 by the unsealing, are folded in the direction 1 onto 2 onto 3. Then the envelope is closed by the glued margins 16 and 18 and the flap 5. A variant intended for a single posting is obtained by eliminating references 16, 5 and 18, the panel 3 being folded onto 2 and then closed as mentioned above.

Description

Hermetically sealed reversible postal fold
Mail items folded into three parts are traditionally closed laterally or longitudinally, which leaves one or two sides open, thereby presenting a risk of entanglement in the machines during the automatic processing of the mail.

In addition, letters, letter cards, envelopes and postcards do not present, on the same medium, a means of paid reply.

The device according to the invention makes it possible to remedy these drawbacks. I1 in fact comprises two closure systems hermetically closing the fold; one at 11 outward, the other on the return, while concealing the return addressing and stamping on the outward journey, and vice versa.

According to a preferred embodiment, the means is a rectangular sheet of paper (or other desired) (for example) divided by folding and perforations, into three main parts forming flaps of desired dimensions making up the body of the fold and carrying the two sides on the front. subscriptions and stamps, the rest being available for correspondence or otherwise. The envelope can also be used as an envelope if necessary, and thus contain a message which can be kept by the recipient.

Figure 1, board 1/4, shows the back of the fold before folding.

Figure 2, plate 2/4, shows the bending in progress.

Figure 3, same board, the fold closed for initial shipment.

Figure 4, board 3/4, shows the fold having been opened.

Figure 5, same board, shows the closed fold to perform the second routing.

Figure 6, plate 4/4, shows a variant of the fold.

The device according to figure 1, pl. 1/4, represents the fold in its constituent parts, designated according to the following references 1- upper flap 2- middle flap 3- lower flap
The desired dimensions of the three shutters are delimited by the references 7 - 8 - 14 -15; which are alignments of perfotations, and the references II - 12 -, which are axes of pivoting of the flaps.

They can be traced, repressed or dotted with perforations. They are located at the desired spacing values.

The flap 4 is provided with a line of perforations 6, parallel to 7 and 10; which is a pivot axis parallel to 6 and 7 which are equidistant from it.

The marks 19-20-21, are glued margins, they meet to form a continuous strip limited by the axis II
Reference 2 is a flap delimited by references 11-12 and 14-15. These margins may not have pasted titles.

3
The shutter mark 1X3 is similar to shutter 1.

The flap 5 is similar to the flap ia except that its glued margins 16-18 are discontinuous.

Figure 2 of plate 2 shows the fold being folded, the flap 5. The margins 1o- 18, are folded beforehand on the shutter 3 and the whole will be folded on the shutter 1. The flap 4 will be folded along the axis 10, then glued according to Figure 3 which has the marks 6 and 7 juxtaposed. The mail is ready for the first shipment.

Figure 4 3/4 board, shows the fold having been opened after reception, by ablation of the glued margins 1, 20, 21 e Only the flaps 1 and 2 remain
For return routing (or other destination), shutter 1 is folded along axis II onto shutter 2 then the assembly onto shutter 3 along axis 12. FIG. 5 shows the fold ready for the second routing. The margins 16 and 18 then the flap 5 folded along the axis. Which juxtaposes the marks 8 and 9. The reference 21 appearing in Figures 5 and 5 represents the margin 21 which remained stuck to the front of the flap 2 after unstealing the fold
Figure 6, of the sheet 4/4, shows a variant of the fold intended for a single routing. This variant is obtained by removing the marks 5, 16, 18, from the sheet 1/4 and following. Component 3 remaining alone, but to which it can add a benchmark component 22.

The flaps will preferably be of decreasing height from flap 2
The envelope, which can also be used as an envelope, is useful, among other things, for philatelic correspondence by the fact that the end result is to present on the front of sections 1 and 3, two subscriptions and related stamps.

Part 2 and the back can receive texts and illustrations.

The means of industrial implementation are those of the paper industry

Claims (1)

1- Device constituting a means of correspondence carrying out two routes without the possibility of confusion between the outward and return subscriptions, the two not being able to enter simultaneously visible, the visualization of one resulting from the concealment of the other. For this purpose the fold is divided into three main parts: an upper flap 1 1/4 board, a middle flap 2, a lower flap 3. These flaps being delimited by alignments of perforations 7, 8, 14, 15 and folding axes 11 and 12. Flap 1 is equipped with a closing flap 4, flap 3 with a closing flap 5 and sticky margins 16 and 18 2- Device according to claim 1 characterized in that, for the first routing, the flap 5 is folded over the flap 3 along the line of perforations 8 3- Device according to claim 1 or claim 2, characterized in that the mark 6 of the flap 4, plate 2/4, figures 2 and 3, pivoting when the fold is closed, on the mark 10 is juxtaposed with the mark 7 thus constituting with the margins 19, 20, 21 a hermetic closure, but easy to unseal, by constituting, Figure 3, a margin with tear perforations, easy gripping 4- Device according to claim 1, characterized in that the flap 3 of Figure 4, plate 3/4, (in confiou- ration second routing) receives flaps 1 and 2 folded on top of each other along the axes It and 12 The marks 16 and 18, figure 5 are glued on the shutter 2, then the flap 5. The marks 8 and 9 are juxtaposed by pivoting about the axis 12. After gluing, the closure is airtight. 5- Device according to any one of claims characterized in that the deletion of the marks 5, 16, 18 according to Figure 6, board 4/4, allows for a hermetic fold single routing. The shutter 3 (possibly extended by a suite 22) is folded, by pivoting along the axis 12, on the shutter 2 and closed by the flap with the same effects as described in claim 2 and the same convenience of opening by the arrangement of the margins figure 7 marks 6, 7 and 15, 18
