FR2783805A1 - Rapid opening arrangement for paper envelopes comprises opening string attached to gripping point formed as pre-cut that is integral envelope format. - Google Patents

Abstract

The arrangement uses an opening string (1) that acts as a cutter and is located on the fold of the flap of the envelope. The string is teminated at the end of the envelope, at the center of a pre-cut semi-circle (2) on either the left side, or another side of the envelope. After closing the gripping point is integrated is integrated into the format of the envelope that may have the classic shape, or have a band attached (3).

Description

-1- The present invention relates to a device for easily opening,

  quickly, cleanly and without instrument envelopes of all sizes, by the use of biodegradable products and allows a

  optional advertising on the envelope.

  The envelope opening system is often manual or

  is carried out using various instruments, such as: paper cutter, opener

  letter or whatever. It turns out that these means are not without risk of

  deteriorate, the contents of the envelope.

  The device proposed according to the invention overcomes the above drawbacks, by allowing envelopes to be opened without any utensils and with little effort, while ensuring security of protection for the documents inserted. the entire fold of the flap, a seam in cotton, silk or linen thread

(figure 1).

  The main interest of this invention is to use as a

  paper cutter, this seam made on the fold of the envelope flap.

  Thus each needle hole can be considered as a stitching serving as a precut and reducing the pulling force of the chain.

of wire at the opening (figure 3).

  The principle of opening the envelope is facilitated by the precut of a gripping point; made by stitching (sewing without

  wire) at the front left corner of the top of the envelope.

  This grip point (FIG. 3) drawn in the form of a quarter of a circle (closed envelope), or of a semicircle (open envelope), is identified by a color different from that of the envelope or another mark, and

  integrates into its central axis the beginning or the end of sewing with thread.

  This invention can be used on envelopes of already existing format, or on envelopes specially designed according to the following indications: the initial length of the format chosen for the interior content, is lengthened by approximately 1 cm. This added surface forms a strip on the left side of the envelope and is intended to integrate the opening grip corner (Figure 3). The headbands

  front and rear are glued together from the manufacturing of the envelope.

  The documents inserted, can therefore in no case slip into

  this unusable part of the envelope.

  -2- While being an integral part of the envelope, this strip is

  reserved as support for the detachable corner and for possible advertising.

  In all cases, it remains independent of its content (Figure 3).

  The interest of this banner is first of all to protect the documents, and to be able to detach the quarter-round opening, without any precaution,

  being guaranteed not to damage the documents contained.

  This strip (the width of the quarter round, or more), drawn on the

  outside on the front of the envelope, can become an advertising medium.

  It will be positioned either to the left or to the right of the envelope, but for more effective advertising, it is better to

  in case, prefer it on the opposite side to the stamps.

  For the sake of aesthetics, the stitching of front stitches is carried out without knots and on the right side of the envelope. So the back of the seam

  only appears on the inside of the fold of the flap.

  In the absence of cotton, linen or silk, excluding the notion

  environment, it can be used polyamide wire or other.

  Add the inviolability of the envelope, because the opening is destructive. -3- The attached figures illustrate the invention Figure 1 shows the back of a conventional envelope with addition

of the banner.

  The seam (1) makes a straight cut reinforced by the thread, above and below the fold of the flap. At the end of the pre-cut semicircle (2), the seam ends or begins. Therefore, after closing, when gripping between

  thumb and index finger, the thread is held.

  On the right, the strip, the inner part of the envelope that cannot be used because it is glued, prevents mail in envelopes from being damaged when opened. Figure 2 shows the front of the envelope before closing. The seam (1) in straight stitch, the loops thus being inside the

envelope flap.

  The pre-cut semicircle (2), identified by a color, or other is

located on the banner.

  The banner (3) advertising support, is preferably located at

left of the envelope.

  Figure 3 shows the opening system by cutting the corner (2) (in a tearing situation) .It allows by a lateral movement of the

  hand, the clean and fast opening of the envelope (1).

Claims (6)

Claims   1 - Device for quickly and safely opening the envelopes (envelopes of paper intended to receive a letter, a document, etc., def. Dict. Encyclopédique Larousse). This device is characterized in that it comprises an opening thread (1) in the form of a seam, on the fold of the envelope flap. This wire ends at the end of the envelope, in the center of a pre-cut semicircle on the left or other part of it (2). After closing the envelope, the gripping point can be integrated into the format of the   classic envelopes or with headband (3).   2 - The device according to claim 1, characterized in that the seam (1) is in normal straight stitch or similar tension adapted to the type of envelope of all dimensions (simple, lined with foam, cells or others).   3 - Device according to claims 1 and 2 characterized in that   that the possible strip (3) of the envelope is formed of two surfaces   pasted not usable for its content.   4 - Device according to any one of claims   previous characterized in that the front side of this strip allows a advertising printing.   5 - Device according to any one of the preceding claims   characterized in that the gripping of the opening corner of the envelope is facilitated by the pre-cutting of a semicircle including   at its central axis the start or end point of the sewing thread.   6 - Device according to any one of the preceding claims   by the fact that the seam can be made of cotton, silk or linen thread used to respect the environment (or polyamide in other cases). These threads can be single-colored, of alternating or assembled colors.
