7 ENVELOPES Filed Oct. 22, 1965 r /NVNTOR 090/? E. HANSON AGENT United States Patent Ofiice 3,369,732 Patented Feb. 20, 1968 3,369,732 ENVELOPES Bror E. Hanson, 3 Bellingham Road, Worcester, Mass. 01606 Filed Oct. 22, 1965, Ser. No. 500,511 1 Claim. (Cl. 229-68) ABSTRACT OF THE DISCLOSURE An envelope suitable for use as an insert in a magazine or other bound publication is provided. A line of perforations extends parallel and close to one end of the envelope and defines a binding portion which may be fixed to the bound edge of the publication and from which the remainder of the envelope may easily be detached by tearing along the perforations. Inwardly of the line of perforations is a line of adhesive which joins the front panel to the back panel of the envelope so that after detaching such remainder from the binding portion the edge adjacent the perforations remains sealed.

This invention relates to envelopes to be used in binding into magazines, periodicals, catalogues, or similar bound publications for the convenient use of recipients of the bound publications in responding to advertisements or the like appearing therein.

An object of the invention is to provide a completely formed envelope which is very simple in construction and can be made on ordinary envelope making equipment.

Another object is to form an ordinary envelope in a certain manner whereby one end thereof may be incorporated in the binding of the magazine, and a complete unmutilated envelope may be removed by simply tearing it out without disrupting the binding of the magazine.

Another Object is to provide a bind-in envelope which may be bound in publications without the provisions of specially designed flaps, extensions, etc.

Still another object is to provide an envelope which is conventional in style and efiicient in its use.

With the foregoing and other objects in view which will appear hereinafter, the invention resides in the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawings but it is to be understood that changes in the form, proportions, and details of construction may be resorted to that come within the scope of the appended claim.

In the drawings wherein like numerals of reference designate corresponding parts throughout the several views:

FIGURE 1 illustrates an envelope according to this invention bound into a publication.

FIGURE 2 illustrates the blank from which the envelope according to this invention is made.

FIGURE 3 illustrates the folded envelope made from the blank shown in FIGURE 2.

Referring in detail to the drawing, denotes the publication having bound edge 12 into which envelope 14 is inserted. Envelope 14 is inserted between any desired adjacent pages P and P; and is preferably of a size and mounted in a position such that the edges of the envelope are entirely within the bounds of the publication.

In FIGURE 2, 16 denotes the unfolded blank from which the envelope 14 is made. The blank comprises a central panel 18 and side flaps 20 and 22 foldable along lines 24 and 26 respectively. Bottom flap 28 is foldable along a bottom fold line 30 to complete the pocket, and the top flap 32 is a sealing flap which is foldable along a top fold line 34 to close and seal the envelope. When the envelope blank is folded to form an envelope, as shown in FIG. 3, the central panel 18 comprises the front panel of the envelope and the side flaps 20 and 22 and bottom flap 28 together comprise the back panel of the envelope.

Before folding the flaps on the blank 16, a strip of adhesive 36 is applied along a line generally parallel to the fold line 24 and spaced a short distance therefrom. The strip of adhesive 36 may be applied either to the central panel 18 or the side flap 20. In this instance it is applied to the central panel 18. When the side flap 20 is folded over onto the central panel 18, the adhesive strip 36 results in a line of connection between the central panel 18 and the side flap 20. Since the side flap forms part of the back panel of the envelope, there is, in elfect, adhesive connection between the front and back panels of the envelope along a line parallel to the edge formed by fold line 24.

Just outward from the line of adhesive 36 is a weakened line 40 of perforations or the like, extending through both the front and back panels of the envelope. This line of perforations may be formed either in the blank before the envelope is formed, or in the completed envelope after the flap is folded over onto the central panel 18. If the perforations are formed in the unfolded blank, then, of course, two parallel lines of perforation 40, equidistant from fold line 24 must be formed. the blank 16 is folded in the normal way, i.e., first the side flaps 20 and 22 are folded, then bottom flap 28 is folded and adhesively connected to side flaps 20 and 22 to form a pocket.

The line of perforations 40 should be spaced just far enough away from the edge 24 to permit the binding portion 42 to be secured in the publication in order to leave as much of the envelope usable on a pocket as possible. That is, as shown in FIG. 3, the line of perforations 40 is so located that the length of the binding portion 42, as measured from the line 40 to the left hand end of the envelope is at least several times smaller than the length of the remainder of the envelope as measured from the line 40 to the other or right hand end of the envelope. The adhesive strip 36 is placed immediately inward from the line of perforations 40.

The invention is not limited to the precise form shown in the drawings, i.e., to envelopes made from rhombic shaped blanks. The invention is equally effective with die cut blanks. It should be clear from the foregoing description and drawings that the envelope is bound in the periodical by means of the end portion 42, defined from the pocket portion by the line of perforations 40. When it is desired to use the envelope, it is simply separated by tearing along the weakened line 40.

The present invention thus provides a simple, easily I constructed envelope which is conventional in form and which is easily used. It will be understood that various changes in the details, materials, steps and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the scope of the invention as expressed in the appended claim.

I claim:

1. An article suitable for use as an insert in a bound publication comprising an envelope formed from a single blank including a central panel, two side flaps, a bottom flap and a top flap, said two side flaps being folded respectively along two parallel end fold lines into overlying relationship with said central panel and said bottom flap being folded along a bottom fold line into overlying relationship with said central panel, said bottom flap being adhered to said two side flaps to form a back panel for said envelope and said central panelcomprising a front panel for said envelope, said envelope having a line of perforations spaced from and generally parallel to one end thereof, said po-rforations extending through both said front and back panels of said envelope and on said back panel said line having a major portion of its length located solely on an associated one of said side flaps, and means connecting said front and back panels together immediately inwardly from said line of perforations, the portion of said envelope located outwardly of said line of perforations serving as a binding portion for attaching said envelope to the binding of a publication such as aforesaid and having a length, as measured from said line of perforations to said one end of said envelope, at least several times smaller than the length of the remainder of said envelope as measured from said line of perforations to the other end of said envelope.
