Detailed Description of the Preferred Embodiments
Referring first to Figure 1, there is shown a blank 10 forming a carton or multi-sleeve booklet
for holding a plurality of articles, for example information discs or the like, made from one or more blanks of paperboard or similar foldable sheet material for example plastics material. Each sleeve comprises a front panel and a back panel which are preferably secured together. The blank 10 comprises a plurality of front panels 12, 14, 16, 18, 20 and 22 arranged in series. In this embodiment, front panels 12, 16, and 20 are hingedly connected to front panels 14, 18 and 22 respectively along fold lines 24, 27, and 30 and front panels 14, 18 are separated from front panels 16 and 20 respectively by cut lines 26 and 28.
There further comprises a plurality of back panels 32, 34, 36, 38, 40 and 42 positioned in series adjacent their respective front panels 12, 14, 16, 18, 20, 22 and hingedly connected thereto along a common longitudinal fold line 54. In this embodiment, back panels 34, 36; 38, 40 are hingedly connected together along fold lines 46 and 50 respectively: fold lines 46 and 50 are co-extensive with cut lines 26 and 28. It will be seen from Figure 1 that back panel 32 is separated from back panel 34 by cut line 44 and likewise, back panels 36 and 40 are separated from back panels 38 and 42 respectively by cut lines 48 and 52.
In another class of embodiments a plurality of panels may be hingedly connected together in series to form in alternating sequence: the front panel of one sleeve being hingedly connected to the back panel of the next adjacent sleeve and so forth. There may further comprise a second set of panels adjacent to and hingedly connected to the panels folded in series. The second set of panels may form the corresponding one of either the front or back panels. Preferably, each of the second set of panels is separated from the adjacent panels in the second set by cut lines. The panels may be folded in "accordion like" fashion, as hereinafter
described. It is envisaged that other modifications can be made, for example the remaining features described below may be incorporated into the class of embodiments described in the preceding paragraph without departing from the scope of invention.
It will be seen from Figure 1 that there may further comprise a plurality of apertures 62 interrupting cut lines 26 and 28 and struck from front panels 14, 16 and 18, 20. The apertures 62 are adapted to provide a display face to show part of a disc contained in the or each sleeve, as shown in Figure 4. The apertures 62 may further comprise one or more recesses 64 to allow a user access to a disc contained in the sleeve, when in use. Optionally, the back panels 32 to 42 may extend beyond the disc contained in the or each sleeve to provide support and to protect the disc should the sleeve be accidentally dropped.
Securing means is provided to secure the front and back panels 12 to 22; 32 to 42 of each sleeve together: in this embodiment the securing means comprises a plurality of side flaps 56 hingedly connected to a side edge of corresponding front panels 12 to 22 along a common longitudinal fold line 58. Adjacent side flaps 56 are preferably separated by cut lines 60.
There may further comprise a spine panel for hingedly connecting the sleeves together. Figure 1 shows a spine panel 66 intermediate back panels 40 and 42 and hingedly connected to the back panel 42 of an outermost sleeve 84 (Figures 3 and 4) along transverse fold line 68. The spine panel 66 is formed from the back panel 40 of a sleeve adjacent to the outermost sleeve 84 and is so constructed to be securably joined to the back panel 32 of the opposed outermost sleeve 82 (Figures 3 and 4) formed by front and back panels 12 and 32 described below. In this embodiment, spine panel 66 comprises second fold line 70 to define a securing flap adjacent the end edge of the outer spine panel 66.
It is envisaged that the size and/or shape of the sleeve can be altered according to manufacturing or user requirements. For example, the height or width of the panels can be increased or decreased according to the size of disc to be held by the sleeve.
The construction the carton is illustrated with reference to Figures 2, 3 and 4: as described above, suitable securing means is used to connect the front and back panels 12 to 22; 32 to 42 of each sleeve. In this embodiment, glue is first applied adjacent the free side edges shown as reference 74 of back panels 32 to 42. Furthermore, glue 74 is applied to the glue flap of spine panel 66, as shown in Figure 2. Thereafter, side flaps 56 are folded about longitudinal fold line 58 in direction A, so that the inner faces of side flaps 56 are moved into face contacting relationship with respective front panels 12 to 22. Back panels 32 to 42 are folded about longitudinal fold line 54 in direction B into face contacting relationship with the outer faces of side flaps 56 and are secured together by glue 74 or other means known in the art.
To form the multi-sleeve booklet 80, the part formed carton is folded in an "accordion like" fashion shown in Figures 3 and 4: whereby the outermost sleeve 82 formed from panels 32 and 12 are folded about fold line 24 and into face contacting relationship with the adjacent sleeve formed from panels 14 and 34 such that, panels 12 and 14 are juxtaposed. The next adjacent sleeve formed from panels 16 and 36 are folded about fold line 46 so that the sleeves formed from panels 14, 34 and 16, 36 respectively are folded into face contacting relationship
with each other. Preferably, the faces of back panels 34 and 36 are placed in face contacting relationship and are secured together by glue or other means known in the art, shown in Figure 4.
Thereafter, the sleeve formed from panels 18 and 38 is folded about fold line 27 into face contacting relationship with the adjacent sleeve formed from panels 16 and 36 with front panels 18 and 16 in juxtaposed relationship. Likewise, sleeves formed from panels 18, 38 and 20, 40 respectively are brought into face contact relationship with each other by folding about fold line 50 so that back panels 38 and 40 may be secured together. The outermost sleeve 84 formed from panels 22 and 42 is folded about fold line 30 so that front panels 20 and 22 come into face contacting relationship with each other. Thus, the carton is constructed as shown in Figure 3 with the disc pockets or sleeves being connected together to define the upper edges 86 and the lower edges 88 of the booklet 80.
Thereafter, the outer spine panel 66 is folded about fold lines 68 and 70 such that the glue flap is brought into abutment with the outer panel 32 of the opposing outermost sleeve 82 formed from front and back panels 12 and 32. Thus, the carton is in the set up condition shown in Figure 4 and can be supplied to the user to provide a multi-sleeve booklet for disc or other like objects.
Beneficially in those embodiments where the board is coated on one side or where printed matter is applied to one side only, the folding process hereinbefore described provides a
booklet in which the coated printed sides are exposed on all of the outer surfaces. It is envisaged that the carton of the present invention can be formed by a series of sequential folding and gluing operations which can be formed in a straight line machine so that the carton is not required to be rotated or inverted to complete its construction. The folding processes are not limited to that described below and can be altered according to particular manufacturing requirements.
It is desirable for cartons containing information discs to be enclosed to protect the or each disc. Furthermore, the carton should preferably be reclosable to allow it to be re-used. In one class of embodiments, there may comprise an outer sleeve 81 shown in Figure 5 so constructed to be used in conjunction with the multi-sleeve booklet 80 of the embodiments described above. The outer sleeve 81 can keep the booklets in a closed condition and prevent unwanted removal of the discs. As shown in Figures 6A and 6B, the multi-sleeve booklet 80 is inserted into the open end of the tubular structure of the outer sleeve 81 through aperture 83 and can be held in place by suitable securing means known in the art.
Advantageously, the embodiment of the invention hereinbefore described provides a structure that is sufficiently strong to retain articles and to provide an integral base. The use of paperboard material provides a degradable alternative to known sleeves formed from plastic material and the sleeves made from paperboard can include printed matter for marketing purposes.
It will be recognised that as used herein, directional references such as "top", "base", "end", and "side" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that hinged connection can be formed from one or more of one of the following, a score line, a frangible line or a fold line, without departing from the scope of invention.
The present invention and its preferred embodiment relate to a carton or multi-sleeve booklet which is shaped to provide satisfactory rigidity to hold items such as compact discs with a degree of flexibility. The shape of the blank minimises the amount of paperboard required for the carton. The carton can be constructed from a flat collapsed condition to a position of use by hand or automatic machinery. It is anticipated that the invention can be modified, without departing from the scope of invention, for example, the panels of the blank of the invention may be arranged such that the front panels are hingedly connected together in series and corresponding back panels being connected to respective front panels, but otherwise separated from adjacent back panels. Thus, the individual fold lines connecting all the sleeves together are formed in series rather than out of alignment with the front and back panels being connected alternately in series, without departing from the scope of invention.
