Abstract
ABSTRACT OF THE DISCLOSURE
A record sleeve for a phonograph record is formed by folding a paper or other flexible web along a transverse fold line so to provide top and bottom panels which are bond-ed together by elongated beads of adhesive material previous-ly applied to one surface of the web generally along two opposed side edges thereof but slightly inwardly of those edges. Before folding, information is usually printed on the outer surface of the web and, after the two panels have been bonded together by the adhesive material, they are trimmed outwardly of the adhesive to eliminate printing bleed. The reduced thickness of the outwardly extending bonded seams permits a less loose fit of the sleeve containing a record in a conventional outer jacket.

~03775S
he present invention relates to the packaging of phonograph records and more particularly to novel sleeves for phonograph records, a method for the manufacture of such sleeves and to certain novel combinations of such sleeves with record discs and outer jackets.
BACKGROUND OF THE INVENTION
The packaging of phonograph records customarily ;- t employs an outer package of relatively stiff card material known as a jacket, and an inner packaging liner of paper or thin plastic stock and usually known as a sleeve.
The dimensional tolerances of the jacket must be !' maintained within quite strict limits so that, on the one hand, they will provide adequate protection for the records and, on the other hand, they will be capable of being received ` in existing display cabinets and shelving in retail outlets.
The jacket is, therefore, a relatively expensive piece of packaging, and is provided with a decorative and usually highly artistic printed surface. The interior of the jacket however i8 usually left untreated and consequently, an additional paper liner is usually provided. Such a liner or sleeve is slipped over the record before the record in such a liner is inserted into the jacket. In this way, the relatively delicate sides of the record are protected against possible scratching or burring by the relatively abrasive inner surfaces of the jacket.
In the past, the liner or sleeve has usually been a simple paper envelope which is left plain without any decora-tion. In some cases, it has been attempted to provide a decorative or printed finish on such a sleeve but various difficulties have, however, arisen. The known sleeves have ~o li usually been made in the fashion of simple paper envelopes consisting of front and back panels, with two side flaps ~;
on the front panel which are folded around the back panel ; and glued onto the outer surface of that back panel. In addition, conventionally a small cut-out or indentation has been formed in the free edge of the front panel of such a sleeve so that the record may be more easily grasped with the fingers and removed from the sleeve.
It is also known that the printing of an artistic or decorative design or any other information on such a paper !, envelope or sleeve presents certain problems. Such printing, in order to have a high quality appearance, must necessarily be carefully registered, and the folding of the side flaps and the front and ba~k panels must then be carried out along exact pre-determined lines. In addition, the folding and gluing of the ~ ;
glue flaps over the outer surface of the back panel will tend to obscure portions of any printing on that back panel and will ¦
thus impair the appearance of the back panel.
Another problem which arises when printing a t . . o relatively low cost item such as a record sleeve results from the fact that the printing, cutting, folding and gluing of the sleeve must be carried out at very high speeds. In such high speed printing on paper stock, generally in roll form, a small ; marginal area known as the "bleed" is left and this must afterwards be cut off since it would otherwise spoil the appearance of the product.
Additionally, the use of side flaps to hoId the sleeve together requires that either the printing area covers the flaps, or that the flaps are left blank. In either case ths "bleed" area alongside the printing creates difficulties.
,. . .
~ ,-..
.,' ., ~0~1~7q55 Thus, either som~ of the bleed, ie. along the side flaps, cannot be cut off at all, or alternativel~ a much larger area of paper stock must be covered with printing, and a relatively large marginal area cut off so as to leave the side flaps extending outwardly from the rest of the blank.
!' In this case however the cutting away of such large marginal areas destroys the oringinal printed image or t pattern and is, therefore, unacceptable. ¦~
In addition, folding and gluing of the side flaps of such a sleeve must be carried out with great precision in order to avoid obscuring parts of the printing.
Thus, while it is probably technically feasible to apply printing and artwork on the front and back panels of a conventional record sleeve having such glued flaps, as a practical matter such a procedure is too expensive and is, - therefore uneconomical.
Another problem results from the fact that the stan- !
dard dimensions adopted in the recording industry create un-desirable characteristics for the overall package.
Thus the standard twelve inch long-playing record as presently marketed has a diameter of about 11 7/8".
Standard record jackets as presently used measure about 12 3/8" by 12 3/8" square.
Such a jacket is usually made with two glue flaps on one of its two panels folded internally and glued to the inner face of its opposite panel.
Assuming that the record is protected within the jacket by a simple paper envelope or sleeve having glued flaps, this means that there will inevitably be a certain degree of free play between the edges of the sleeve and the inner limits . . .
..... . , . ~.. ,, .... ~
/
; 1~377S~ , of the jacket. Such free play will amount to between 1/4n ~t and 3/8" depending upon the thickness of the card stock used in the jacket, the thickness formed by the card where it is folded over around the edge of the jacket and the thickness of the sleeve.
; A purchaser handling a record in such a jacket will, therefore, be conscious of a slight movement of the record with-in the jacket if the jacket is shaken for example. Movement across the surface of the record is in fact undesirable since almost any material may contain impurities which may cause burrs or scratches on the delicate surface of the record. No attempt has heretofore been made, however, to provide the record paskage in which a record is as far as possible securely held against such sliding movement within the jacket.
The fact that the slight degree of movement of records in existing jackets may or may not in fact cause any surface damage is believed to be irrelevant. It is believed that this factor is essentially a psychological one, ie. that it is un-desirable for the prospective purchaser to be given any cause, even an imaginary cause, for concern as to the condition of the record within the package.
In the past however, this degree of clearance and free play has been assumed to be essential in order to permit the record to be slid in its sleeve readily into and out of the package.

The pre-~ent invention provides a record sleeve which can be printed on both its front and back panels, for examp~e, with a decorative, informative or artistic appearance, and in ,:
which the two side edges of its panels are glued or otherwise ., :
~037755 adhesively bonded face to face along marginal strips, with-out the use of side flaps.

In this way the special die cutting step, formerly required to provide glue flaps and a finger recess, is no longer needed.
The printing, folding, gluing and cutting operations - can then be carried out at much higher speeds and in a contin-uous sequence.
Preferably the marginal strips formed by the elongated beads of adhesive material have widths of between about 1% and
2~ of the overall width of the sleeve, and thicknesses only slightly more than the thic~ness of the two panels of paper - 20 stock. In this way, the free space along two sides of the sleeve is at least partially filled up without producing a binding action on the edges of the record which would otherwise prevent it from being slid into and out of that sleeve.
In addition to providing a novel record sleeve, this invention also provides a novel combination of such a sleeve with a record removably disposed therein, a novel combination of such a record-containing sleeve disposed in a novel manner within - a conventional record jacket, and a novel method for the manu-facture of a record sleeve.

DESCRIPTION OF THE PREFERRED EMBODIMENT
.,- . . :
Referring first to Figure 1 of the accompanying draw--~ ings, it will be seen that the invention in general relates to the packaging of records, of the type in which a record shown at R is packaged in a protective jacket indicated generally at 10, and with an inner lining or sleeve 12, fitting within the jacket at 10.
- ~he jacket 10 comprises front and back panels 14 and .' . :
., ~ .
' . . : ..... : .
:
1~)37755 16, joined along one edge by a common fold line 18, and joined along two side edges by means of internal glue flaps s 20 (see Figure 5).
The jacket 10 is usually printed on both panels 14 and 16 with a highly decorative design or artwork, and with lyrics or biographical material relating to the author or per-formers. As such, jackets 10 are essentially conventional and well known in the art. i~
As described above, the packaging of records conven- 1 ;
10tionally has employed a liner or record sleeve fitting within the jacket 10, for protecting the record R. The typical prior art sleeve consisted of a simple paper envelope having front and back panels and glue flaps extending outwardly from the front panel, and folded around the exterior of the back panel and glued thereto so as to provide a rectangular or square envelope closed on three sides. In addition, such a known ~leeve typically had a finger recess cut out of one of its panels so that the record could be grasped more easily.
. . .
Such a prior art sleeve containing a record usually 20fitted fairly loosely within its jacket 10 and, in particular, did not completely fill the space within the jacket 10, par-ticularly in the region of the internally folded glue flaps ' 20 (Figure 5) of the jacket 10 where, in any event, the space between the top and bottom panels within the jacket 10 tends to be somewhat more restricted.
In accordance with the invention, therefore, there is provided an improved form of record sleeve generally shown at 12. The sleeve 12 will be seen to comprise a front panel 22 and a back panel 24. The front and back panels 22 and 24 30are joined along a common fold line 26 ~see Figure 2) which is .
~037755 1~ ~
positioned so as to provide a front panel 22 which is slightly shorter than the back panel 24 thereby leaving a marginal edge portion 24a of the back panel 24 extending beyond the edge of the front panel 22.
The dlmensions of front panel 22 are such that its length from the fold line 26 to the opposite edge 27 is slightly less than the diameter of the record R, and the back panel 24 has a length equal to, or slightly longer than the diameter of the record R. In this way, an edge portion of the record R will appear to project beyond the edge 27 of the front panel 22, thereby making it easier to grasp the record with the fingers.
In thiY way, it is no longer necessary to die cut out a finger recess and such cutting step is, therefore, ; avoided, thereby speeding up the manufacture of the sleeve 12.
It will also be noted that the record sleeve 12 does not employ glue flaps. Instead, the two side edges of the panels 22 and 24 are glued face to face. This is achieved , in the following manner. As best shown in Figures 2 and 3, a relatively narrow elongated bead of liquid adhesive 28, is applied to the upper face of the front panel 22 longitudinally along both side edges 30 of the front panel 22. -The beads 28 are spaced inwardly from the side limits of the panel 22 for reasons yet to be described. The adhesive 28 is ~ m of any suitable type but~ preferably is one having a relatively short curing time, and may typically be of the hot melt type. I
The back panel 24 is left free of any adhesive I -material. When the panels 22 and 24 are folded along the fold line 26, and the side edge portions 30 and 32 are brought together and pressure i8 applied in that region, the beads 28 '~.
8 ~ ~
10377S5 t of adhesive material will be squeezed and flattened into 3 wider bands 28a ~Figure 4) and will then bond the panels 22 and 24 together.
In this way, the edge portions 30 and 32 of the p~nels 22 and 24 and the thin layer of adhesive 28a there-; between together form sleeve 12 and those portions have ~, thicknesses only very slightly greater than the thickness of the two panels 22 and 24 themselves.
The panels 22 and 24 are usefully initially somewhat wider than the width re~uired for the finished record sleeve 12. They can then be printed by any suitable and conventional high speed printing technique on their outwardly directed sur-., ~ . .
faces with such printing leaving marginal areas or "bleedn portions along the outwardly directed surfaces of the side ?
edges 30 and 32. Such bleed areas present an unsightly appear-; ance. Accordingly, in the manufacture of the sleeve according to the novel method of this invention, the outer margins of the side edge portions 30 and 32 are cut off to eliminate such bleed areas. Such a marginal bleed area is indicated in Figure 3 as having a width dimension "a". Such marginal bleed - portion is shown in phantom only in Figure 4 since by that time in the production operation it has already been removed.
In addition, Figure 3 and 4 illustrate the bead 28 of glue having an initial width as indicated at "b", and a final width as indicated at "c" after pressure has been applied.
In accordance with the invention, it is desirable that the final width dimension "c" of each bead of adhesive material shall be between 1% and 2~ of the overall width of the sleeve as indicated at "w" in Figure 1. In this way, a semi-rigid laminate edge portion is provided along each side , 1:
_ g ~.
,- ~ ,: .
~ ~0377S5 edge of the sleeve 12, which edge portion extends at least partially into the side edges of the jacket 10, in the region of the overlapping glue flaps 20 as shown in Figure 5. Such a jacket 10 is then more or less substantially filled by the side edges of the sleeve without, however, impairing the ability :~ of the sleeve 12 containing the record R to be slid readily into and out of the jacket 10.
~ In addition, the laminate marginal areas, since they ; are only slightly thicker than the total thickness of the two panels of the sleeve and since the record R cannot move into such marginal areas, fill the side edges of the jacket while, at the same time, restraining the record R from moving into such side edges of the jacket. So, they serve to retain it securely in - position so that the ability of the record R to move within the ~ ;
jacket or sleeve is almost entirely eliminated.
The dimensioning of the marginal areas is found, as already indicated preferably to be within from about 1% to about t 2% of the overall width of the sleeve. If the width of the - .
marginal area increases substantially beyond this limit then it -might become easily deformed or crumpled up so that it would no longer perform its intended function, and would, in fact, obstruct the insertion of the sleeve 12 into the jacket 10. ;
On the other hand, if the marginal area were much less than l~
of the width of the sleeve, then the bonding achieved by the glue layer 28a might be inadequate and the sleeve might ea~ily rupture.
., .
It should, however, be appreciated that the selection ~,~
of a suitable width for each elongated bead of adhesive material 28a (after flattening) will be dependent upon such factors as the flexibility of the material from which the sleeve panels 22 ~;
.. r ,.
. .
~ .
~037755 .
and 24 are formed and the final rigidity of the adhesive material itself.
~-. According to a further feature of the invention ;: the bonded laminate edge seams 30 - 32 of the sleeve 12 may be provided with indentations or crimping, such as the lengthwise crimping 34 shown in Figure 7.
This will have the effect of further improving the bonding action of the adhesive, and will also improve -the ~ . .
.` rigidity of the edge seams.
Having described what is believed to be the best mode . by which the invention may be performed, it will be seen that .l the invention may be particularly defined as follows:
¦ A method of manufacturing a record sleeve of pre-determined length and width which comprises the steps of, forming a web of flexible material with a predetermined length . and width the width being greater than the width of the sleeve, : applying printing on said web on one surface thereof extending ~; from one side edge to~:the other side edge, with marginal bleed portions adjacent said side edges, applying a pair of elongated : 20 beads of adhesive material in essentially equal lengths on the other surface of said web in spaced apart parallel relation along : said side edges thereof commencing at one end of said web and . spaced inwardly from said edges whereby to leave peripheral portions of said side edges outwardly of said beads which are free of adhesive material, said beads having a length less than one-half . that of the length of said weh, folding said web along a fold line extending transversely between said side edges thereof . adjacent to the termination of said beads so to provide a first : longer panel overlying a second shorter panel carrying said ; 30 beads of adhesive, applying pressure to said first panel in .. :~

registration with said beads whereby to squeeze and flatten same causing said adhesive material to flow at least partially into said peripheral portions and procuring mutual bonding of said -first and second panels along said side edges by said adhesive material, and, cutting off marginal strips of said bonded first and second panels along said side edges to remove part of said peripheral portions, and said bleed areas of said printing, whereby to define said predetermined width of said sleeve.
The invention further comprises a method haviny the foregoing features wherein the glue beads each have a final width, after flattening and cutting, of between one and two percent of the width of said panel between said beads.
The foregoing is a description of a preferred embodi-ment of the invention which is given here by way of example only. The invention is not to be taken as limited to any of the specific features as described, but comprehends all such .
- variations thereof as come within the scope of the appended claims.

In accordance with the invention, therefore, there is provided an improved form of record sleeve generally shown at 12. The sleeve 12 will be seen to comprise a front panel 22 and a back panel 24. The front and back panels 22 and 24 30are joined along a common fold line 26 ~see Figure 2) which is .
~037755 1~ ~
positioned so as to provide a front panel 22 which is slightly shorter than the back panel 24 thereby leaving a marginal edge portion 24a of the back panel 24 extending beyond the edge of the front panel 22.
The dlmensions of front panel 22 are such that its length from the fold line 26 to the opposite edge 27 is slightly less than the diameter of the record R, and the back panel 24 has a length equal to, or slightly longer than the diameter of the record R. In this way, an edge portion of the record R will appear to project beyond the edge 27 of the front panel 22, thereby making it easier to grasp the record with the fingers.
In thiY way, it is no longer necessary to die cut out a finger recess and such cutting step is, therefore, ; avoided, thereby speeding up the manufacture of the sleeve 12.
It will also be noted that the record sleeve 12 does not employ glue flaps. Instead, the two side edges of the panels 22 and 24 are glued face to face. This is achieved , in the following manner. As best shown in Figures 2 and 3, a relatively narrow elongated bead of liquid adhesive 28, is applied to the upper face of the front panel 22 longitudinally along both side edges 30 of the front panel 22. -The beads 28 are spaced inwardly from the side limits of the panel 22 for reasons yet to be described. The adhesive 28 is ~ m of any suitable type but~ preferably is one having a relatively short curing time, and may typically be of the hot melt type. I
The back panel 24 is left free of any adhesive I -material. When the panels 22 and 24 are folded along the fold line 26, and the side edge portions 30 and 32 are brought together and pressure i8 applied in that region, the beads 28 '~.
8 ~ ~
10377S5 t of adhesive material will be squeezed and flattened into 3 wider bands 28a ~Figure 4) and will then bond the panels 22 and 24 together.
In this way, the edge portions 30 and 32 of the p~nels 22 and 24 and the thin layer of adhesive 28a there-; between together form sleeve 12 and those portions have ~, thicknesses only very slightly greater than the thickness of the two panels 22 and 24 themselves.
The panels 22 and 24 are usefully initially somewhat wider than the width re~uired for the finished record sleeve 12. They can then be printed by any suitable and conventional high speed printing technique on their outwardly directed sur-., ~ . .
faces with such printing leaving marginal areas or "bleedn portions along the outwardly directed surfaces of the side ?
edges 30 and 32. Such bleed areas present an unsightly appear-; ance. Accordingly, in the manufacture of the sleeve according to the novel method of this invention, the outer margins of the side edge portions 30 and 32 are cut off to eliminate such bleed areas. Such a marginal bleed area is indicated in Figure 3 as having a width dimension "a". Such marginal bleed - portion is shown in phantom only in Figure 4 since by that time in the production operation it has already been removed.
In addition, Figure 3 and 4 illustrate the bead 28 of glue having an initial width as indicated at "b", and a final width as indicated at "c" after pressure has been applied.
In accordance with the invention, it is desirable that the final width dimension "c" of each bead of adhesive material shall be between 1% and 2~ of the overall width of the sleeve as indicated at "w" in Figure 1. In this way, a semi-rigid laminate edge portion is provided along each side , 1:

,- ~ ,: .
~ ~0377S5 edge of the sleeve 12, which edge portion extends at least partially into the side edges of the jacket 10, in the region of the overlapping glue flaps 20 as shown in Figure 5. Such a jacket 10 is then more or less substantially filled by the side edges of the sleeve without, however, impairing the ability :~ of the sleeve 12 containing the record R to be slid readily into and out of the jacket 10.
~ In addition, the laminate marginal areas, since they ; are only slightly thicker than the total thickness of the two panels of the sleeve and since the record R cannot move into such marginal areas, fill the side edges of the jacket while, at the same time, restraining the record R from moving into such side edges of the jacket. So, they serve to retain it securely in - position so that the ability of the record R to move within the ~ ;
jacket or sleeve is almost entirely eliminated.
The dimensioning of the marginal areas is found, as already indicated preferably to be within from about 1% to about t 2% of the overall width of the sleeve. If the width of the - .
marginal area increases substantially beyond this limit then it -might become easily deformed or crumpled up so that it would no longer perform its intended function, and would, in fact, obstruct the insertion of the sleeve 12 into the jacket 10. ;
On the other hand, if the marginal area were much less than l~
of the width of the sleeve, then the bonding achieved by the glue layer 28a might be inadequate and the sleeve might ea~ily rupture.
., .
It should, however, be appreciated that the selection ~,~
of a suitable width for each elongated bead of adhesive material 28a (after flattening) will be dependent upon such factors as the flexibility of the material from which the sleeve panels 22 ~;
.. r ,.

and 24 are formed and the final rigidity of the adhesive material itself.
~-. According to a further feature of the invention ;: the bonded laminate edge seams 30 - 32 of the sleeve 12 may be provided with indentations or crimping, such as the lengthwise crimping 34 shown in Figure 7.
This will have the effect of further improving the bonding action of the adhesive, and will also improve -the ~ . .
.` rigidity of the edge seams.
Having described what is believed to be the best mode . by which the invention may be performed, it will be seen that .l the invention may be particularly defined as follows:
