Multiple disc trays have angled stored discs to provide maximum storage space and strength with minimal tray material.
A new multiple disc holder has a thin plastic tray having rectangular outer sides and ends. Outward extending rims are formed on lower edges of the outer sides and ends. A paperboard base is attached to the outward extending rims. Upper surfaces extending inward from the outer sides and ends. Segmental inner end surfaces and opposite segmental inner side surfaces extend downward from the upper surfaces. Recessed finger well surfaces extend outward between the segmental inner end surfaces and adjacent opposite segmental inner side surfaces. Disc-supporting opposite ledges extend inward from lower edges of the segmental inner end surfaces and the opposite segmental inner side surfaces. A lower surface extends inward from the ledges.
The disc-supporting ledges are arranged in first and second opposite pairs. Ledges in the first opposite pair of ledges are parallel to the lower surface. Ledges in the second opposite pair are sloped upward and inward from one end of the tray toward a center.
A disc-retaining rosette is provided in the lower surface concentric with opposite segmental opposite inner side surfaces and an adjacent segmental inner end surface.
A flap is formed in the lower surface extending inward from a hinge on the lower surface near a segmental inner end wall. A disc-retaining rosette extends upward from the flap. At least one extension extends downward from the flap near the hinge for raising the flap above the lower surface.
Inward and downward sloped walls extend downward and inward from upper surfaces near corners of the tray between outer side and end surfaces and inner segmented surfaces for rigidifying the tray and forming bottom surfaces for attachment to a paperboard base.
The outer sides and ends of the tray are sloped inward and upward and the segmental end and side surfaces are sloped inward and downward for rigidity and stacking. The outward extending rims attached to lower edges of the outer sides and ends are spaced for separating and stacking.
A paperboard has a base secured to the rims and extending under the lower surface to a lower crease. The paperboard extends upward in a spine to an upper crease. The paperboard extends from the upper crease over the upper surfaces of the tray as a cover.
The tray, its surfaces and elements are constructed as a single vacuumed-formed sheet.
A disc holder has upward and inward sloping outer side and end surfaces. Upper surfaces extend inward from the outer surfaces. Opposite segmental inner end surfaces slope downward and inward from inner edges of the upper surfaces. First and second opposite segmental pairs of inner side surfaces slope downward and inward from inner edges of the upper surfaces. Segmental lower ledges extend inward from lower edges of the opposite segmental inner end and side surfaces. The ledges on a first pair of opposite segmental sides are horizontal. The ledges on a second pair of opposite segmental sides are sloped upward from an end toward a center of the tray. Disc retainers are provided on the tray.
A hinged flap is formed on a bottom of the tray and extends inward toward a center of the tray. A first rosette is positioned on the tray between the first pair of opposite edges. The second rosette is positioned on the flap between the second pair of sloped segmental ledges.
A disc holder tray has sides, ends and a disc-holding well formed with inner opposite ends, paired inner curved opposite sides, and lower ledges on the curved opposite sides, the ledges on a first pair of opposite curved sides being horizontal, and the ledges on a second pair of opposite curved sides being positioned upward toward a center of the tray, and disc retainers on the tray.
A hinged flap is formed on a bottom of the tray and extends inward toward a center of the tray. The disc retainers comprise first and second disc-holding rosettes, the first rosette being positioned on the tray between the first pair of opposite curved sides, and the second rosette being positioned on the flap between the second pair of opposite curved sides.
Disc retainers are integrated in the curved inner side surfaces and spaced upward above the ledges.
Further disc retainers are integrated in the inner end surfaces.
Inner curved side surfaces are interrupted by vertical separations into relatively long portions near ends of the tray and relatively short portions near a center of the tray, and the retainers are formed in the relatively short portions.
Printed jackets and trays are attached with spots of adhesive material. The trays are easily detached from printed jackets for separate recycling of the plastic trays and paper jackets.
All surfaces of the jackets are printed with colorful attractive graphics, including the surfaces to which the trays are attached and the spines.
The jackets are die cut and creased from card stock. Two spaced inner flaps are glued to insides of the cover and base. A third half-panel flap is folded inward from an outer edge of the cover and is glued to an inward-folded small flap on the bottom of the cover, forming a pocket to receive literature and pamphlets concerning the discs.
Trays are formed with rectangular sloping outer walls with flat outward extending rims which are useful in unstacking trays and locating trays on jacket bases. Tops of the trays are flat. Sloping inner walls have larger segmental walls at longitudinal ends of the trays. Finger recesses having sloping walls at corners of the trays terminate the segmental walls.
Two or more slightly shorter opposite side segmental sloping walls intersect at longitudinal centers of the tray sides or at points along the trays when more than two discs are accommodated.
The opposite side segmental walls have rims which keep major surfaces of the discs from contacting the trays or each other.
At least two of the opposite side segments have sloped rims or ramps which support discs on an angle to the flat bases of the trays.
One form of the trays has self-formed flexible rosettes radially centered between two opposite side segmental walls. At least one flap is formed from the tray bottoms. The flaps have self-formed flexible rosettes radially centered between two opposite side segmental walls. The flaps bend to accommodate and hold discs on the sloped rims or ramps of the opposite side segmental walls. The flaps bend sufficiently so that a disc connected to a flap need not be removed to access and remove a disc on another rosette.
The retainers in the rosettes are small wedge-shaped retainers sloping downward and radially outward and then inward and downward so that the wedge-shaped retainers overlie inner openings in discs which are held between the retainers and the bases of the rosettes.
Surfaces of the rosettes below the retainers cooperate with the opposite side segmental surfaces to keep the discs centered in the trays.
Small semi-cylindrical protrusions between the attached ends of the flaps and the rosettes on the flaps contact the jacket to keep free ends of the flaps raised and separated from lower discs.
Outer areas of the trays between the end segmental walls and finger wells and the outer end surfaces have sloped wall end recesses for increasing rigidity of the thin trays. Rigidity of the trays is increased by attachment of the trays to the bases of the paperboard stock jackets, by the end recesses and by the sloped walls of the thin trays.
One form of the invention uses no rosettes. Wedge shaped retainers are provided in the segmental walls. The sloping bottoms of the retainers are spaced upward from the rims and ramps a distance equivalent to the thickness of the discs. Removing or inserting discs from and into the trays causes the wedge shaped retainers to deform elastically outward the thin walls in the area of the retainers. The retainers then snap inward, holding the discs or being ready to tip outward when inserting a disc.
These and further and other objects and features of the invention are apparent in the disclosure, which includes the above and ongoing written specification, with the claims and the drawings.
Referring to the drawings, trays 10, 12 and 14 are formed with rectangular sloping outer walls 11 with flat outward extending rims 13 which are useful in unstacking trays and locating trays on jacket bases. Tops 15 of the trays are flat. Sloping inner walls 17 have larger segmental walls 21, 22 with inward extending ledges or rims 28, 48 at longitudinal ends 23 of the trays 10, 12 and 14. Finger recesses 25, having sloping walls 27 at corners of the trays, terminate the segmental walls 21, 22, 31, 33, 35, 37. Bases 29 of the trays 10 are flat.
Two or more slightly shorter opposite side segmental sloping walls 31, 33, 35, 37 intersect at longitudinal centers 39 of the tray sides 41 or at opposite points along the tray sides, when more than two discs are accommodated.
The sloping segmental end wall 22 and opposite side segmental walls 31, 33 have ledges or rims 28, 43, 45 which keep major surfaces of the discs from contacting the bases 29 of the trays 10, 12 and 14.
At least two of the opposite side segmental walls 35, 37 and end segmental walls 22 have sloped ramps 47, 49, 48 which support discs at an angle to the flat bases 29 of the trays 10, 12 and 14.
Outer areas 51 of the trays between the end segmental walls 21, 22 and finger wells 25 and the outer end surfaces 53 have sloped wall end recesses 55 for increasing rigidity of the thin trays 10, 12 and 14. Rigidity of the trays is created by the end recesses 55 and by the sloped outer walls 11, and sloped inner curved segmental walls 21, 22, 31, 33, 35, 37, and sloped finger recess walls 27, which form trusses in the thin trays and by attachment 120 of the trays 10, 12 and 14 to the bases 110 of the card stock paper jackets 100 as shown in
