GARR@ GRAMOPHONE RECORD SLEEVE Filed Oct. 23, 1962 United States Patent O 3,116,870 GRAMHNE RECORD SLEEVE Norman .lohn Garrod, 107 Westhail Road, l/Varlingham, England Fiied Oct. 23, 1962, Ser. No. 232,555 Ciaims priority, application Great Britain Get. 23, 1961 6 Claims. (Cl. 229-68) The present invention relates to an envelope type packet suitable inter alia for the reception of gramophone records. Such packages are frequently referred to as record sleeves and will hereinafter be referred to as sleeves which expression shall not in this specification be limited specifically to gramophone record sleeves.

In our co-pending application No. 1914, now Patent No. 3,061,171, there is described and claimed a sleeve formed from two separate pieces of sheet material joined around three edges so that the front of the sleeve can be made of a different material from, and have a different finish to the back. In the construction shown and claimed in this co-pending application the front and back pieces of material were joined around the edges on three sides by the ilap or aps extending from one of the covering sheets applied to one of the sides of the sleeve. Such a construction gives a suitably strong edge if the iiap is made of sutiiciently stout material and in the case of gramophone record sleeves this has usually comprised good quality paper laminated with plastic film such as a transparent cellulose acetate lm.

An object of the present invention is to provide a construction of sleeve in which the joins between two adjacent edges of sheet material is made and reinforced without the requirement of having a strong overlapping material covering the edges of the sheet material and the marginal portions adjacent thereto.

According tov the present invention a sleeve for receiving a gramophone record and similar dat articles has a sleeve edge formed by a marginal extension of one of the faces of the sleeve folded back upon itself to form the edge of the sleeve, the other face of the sleeve being cut short so that its edge lies close to and in the same plane as the folded marginal extension, there being provided between the two edges a closing sheet-like element which is adhered to the inner face of one of the edges and the outer face of the other edge. Conveniently the closing element is a strip or sheet of paper plastic or like material.

Normally the material passing between the join comprises an all over sheet which serves also to carry printed matter on that side of the sleeve. Conveniently, the edge and the marginal portions may be covered by material which may comprise the flap of a sheet secured to the other side of the sleeve and in the case of record sleeves may constitute the front of the sleeve and carry pictorial and/ or writing matter.

The invention will now be described with reference to the accompanying drawings in which:

FIGURE 1 shows diagrammatically and in cross-section a fragmentary portion of one edge of a sleeve suitable for gramophone records; and

FIGURE 2 shows in section one stage in the assembly of the sleeve.

Referring to FIGURE 1 which shows a cross-section of one edge of a record sleeve the body of the sleeve comprises a front sheet 1 and a back sheet of chipboard.

Sheets

1 and 2 may be two separate sheets or they may comprise one sheet of chip-board folded to form one edge. The edges of the sleeve not formed by a fold between the

sheets

1 and 2 are formed by extending the edge of the sheet 1 beyond the required ultimate dimensions of the sleeve so as to form a marginal portion 3 and sheet 2 is cut short of the required dimensions of the

sleeve

3,1%,870 Patented Jan. 7, 1964 ICC by an amount equal to or slightly greater than the Width of the marginal portion 3. To assist folding the sheet 1 may be cut partially or scored as at 4. The sheet 2 is assembled with the sheet 1 as shown in FIGURE 2 and a thinner sheet for example of paper 5 of the size of the ultimate sleeve is applied to the sheet 2 and may be glued thereto, so that the marginal portion of the sheet 5 extends up to or nearly up to the point of fold.

The face 6 of the marginal portion 3 after having an adhesive applied thereto is then turned over to form the fold to the position shown in FIGURE l so that it adheres to the face of the paper sheet 5. In this way the marginal portion 3 is held in position and any adhesive surplus to requirements is prevented from leaking into the fold and causing sticking of the inside faces of the front and back of the sleeve. The normal flap 8, forming an extension of the facing sheet 7 is folded over the edge and secured down to the back of the sleeve to cover the join between the portion 3 and the edge of the sheet 2 and also to reinforce the edge. In view of the fact the edge of the sleeve, which is where the sleeve is most likely to distort, is reinforced by forming it from the folded Inarginal portion of sheet 1 the ap 8 does not require to be of any specific or special strength. However, if reinforcement is required along the edge then the liap 8 can be adhered around the edge by means of a polyvinyl or like adhesive which when set provides a plastic reinforce- Each edge of the sleeve may, if desired, be constructed in this manner and whilst it is normal for the front sheet to be extended marginally to form the fold it will be realised that on one or more of the edges of the rear sheet may be extended and the front sheet cut short. The sheet 5 may, if desired, consist merely of a strip of paper or other suitable material which is adhered marginally to the sheet which is cut short so as to extend between the edges of the front sheet and the back sheet of chip-board in the manner described with reference to FIGURES 1 and 2.

In addition to the great advantage afforded by the present invention so far as the reinforcing of the edges is concerned it has been found that by being able to fix down the marginal portion 3 this can be reduced to a minimum width. When the sleeve is used as a record sleeve this has the advantage that the join between the marginal portion 3 and the sheet 2 does not lie upon the playing portion of the record which, if it did, might damage the delicate playing grooves of the record. Furthermore, the sheet 5 extending into the inside of the sleeve at the marginal edge portion acts as a flashing and prevents any adhesive squeezed out from between it and the inside face of the marginal portion 3 leaking into the inside of the sleeve to stick the inside faces of the sleeve together.

By means of the present invention the strength of the edge does not rely largely upon the strength of the Hap S as it has done heretofore in known constructions where the overlapping iap 8 constitutes the sole join between the front and back sheets. In such prior constructions it has been proposed to reinforce such a join by gluing a further strip of material over the edge portion. This, however, is expensive in that it occupies a separate operation in the manufacture of such sleeves.

Furthermore, since the operations necessary to form a sleeve `do not involve overlapping material to form the join the invention may be used in the construction of sleeves in which the llap 8 is eliminated. In such cases the join 'between the marginal portion 3 and the sheet 2 may if desired be covered by a narrow strip of material, for example, a strip of glued paper. This enables the front `sheet to be eliminated and the chip-board 1 can where desired, carry pictorial or other matter. Alternatively, the edge may be covered by a strip of material.

Whilst the invention has been described specifically with reference to a sleeve in which the body comprises a front or back of chip-board it will be realised that the invention can be `applied to any other form of sleeve constructed from sheet material.
