  • An annular anti-friction reel bearing support 43 (FIG. 2) which projects concentrically with spindle 23 slightly outwardly from the floor 45 of the recess 15 provides a seat on which the flange 31 engages when said reel is disposed in operative position.
  • support 43 is shown as an upward projection in the well 15 from the housing of the spindle drive assembly 21.
  • a closure in the form of a flap 47 is hingedly or pivotally connected to each side of the reel flange 29.
  • a mounting or journalling lug 49 (FIG. 4) which may be of integral fabrication with flange 29 projects outwardly from the end portion of each side of said flange.
  • Each lug 49 serves as a mount for a hinge pin 51.
  • the opposite end portions of each flap 47 have a pair 'of recesses 53, respectively, in the upper or inner flap side to receive the lugs 49 from a corresponding side of flange 29.
  • Each recess 53 is proportioned to accommodate a biasing spring 55 which is disposed adjacent an associated lug 49 and coiled about a corresponding hinge pin extension.
  • the opposite ends of each spring 55 engage, respectively, an associated flange 29 and an adjoining flap 47, the springs 55 being coiled and arranged to bias the flaps to open condition.
  • the association or arrangement of the flaps and the reel flange 29 is such that under spring biasing action when the flaps are completely open, as illustrated in the dashed lines in FIGS. 1 and 2, said flaps will be disposed coplanar with said last flange and thereby permit web removal from chamber 32 as the reel is spindle-rotated in a playing direction.
  • FIGS. 1 and 2 A partially open condition of one of the flaps is illustrated in FIG. 4.
  • the flaps are arranged in overlapping end-to-end relationship with each flap extending normally to a pair of adjoining flaps.
  • the flaps are arranged in a general rectilinear association, substantially defining a square in the present embodiment when closed, with one end of each flap overlapping an adjoining end of one adjacent flap in a manner such that each flap has one overlapping end and one overlapped end.
  • each flap is proportioned in a manner such that what is considered the height of each flap is adequate to substantially completely close or cover the web chamber 32, as illustrated in solid line in FIG. 2. Obviously, more or less than the disclosed four flaps can be used, if desired.
  • An interlockable latch 57 which may be integral with flange 31 propects outwardly from a medial part of each flange side.
  • Each latch has a slightly enlarged or undercut head 59. (FIGS. 3 and 4), whereby a slight snap trough 61 is formed between latch head 59 and its flange 31.
  • Extending inwardly from what may be considered the lower or outer side of each flap 47 is a recess 63 (FIG. 3) which is disposed for snapping interlocking reception of a corresponding latch head as such flap is swung or moved from open to closed position.
  • Said reel may be proportioned for use on a conventional record tape player of the type normally accepting circular profiled reels.
  • the flaps will require manual unlatching by snapping them over the latch heads 59, all interlocking parts preferably being fabricated to yield easily.
  • the record glayer 11 may be modified to automatically unlateh the aps.
  • An integral boss 69 which is considered as projecting downwardly or outwardly from each flap, is proportioned to hang below said flat or plate 65 when such flap is closed. Each boss is proportioned for engagement with an adjacent cam surface 67 upon rotation of the reel. The cam surfaces are proportioned to apply outward pressure of unlatching magnitude on the closed flaps when engaged by rotating bosses 69, as illustrated in FIG. 4.
  • the plate (which corresponds to plate 65) is fashioned to provide only a single throw or cam projection 167. The latter is adapted to unlock all of the flaps successively as the reel 27 rotates to carry each flap past a single flap-unlocking station.
  • a reel generally designated 127 comprises what is considered an upper flange 129 and a lower flange 131, said flanges being parallel and spaced apart vertically or axially.
  • Spring-biased flaps 147 are hingedly connected to flange 129 in a manner which is shown as being the same as that for the connection of the flaps 47 to the flange 29. Flaps 147, however, are releasably secured in container-forming association by different means than are used to secure flaps 47.
  • each side of the lower flange 131 is cut away to provide a pair of spaced apart resilient fingers 163 extending to the edge of flange 131.
  • a recessed flat 173 extends between each pair of fingers.
  • An integral projection 169 extends from each flange 147 and is proportioned and arranged for frictional and releasable engagement between each pair of resilient fingers 163. The disposition of each flat 173 is such that when its associated projection 169 is fully engaged in its recess, in the manner illustrated in FIG. 6, to close the reel chamber, flaps 147 will be disposed normal to the flanges 129 and 131.
  • each part or boss 169 is seen to be adapted for engagement by a latch trip or cam surface 167 to disengage the flaps 147 from retained position.
  • a flap 247 is fabricated integrally with each of the sides of the upper reel flange 229 to which said flaps are hinged by means of marginal lines of thinned material 251.
  • the character of the material is such that the flaps 247 are biased toward the plane of the flange 229.
  • the thinned material facilitates bending of the flaps to condition them normally to the reel flanges 229 and 231 to closed position by manipulation from the dashed line to the solid line position of FIG. 9.
  • a medial part of the inner edge portion of each thereof is fashioned with a groove 249.
  • a leaf or band spring 253 is associated with each flap 247 and has one end portion suitably connected by a fastener, such as a rivet 255, to the reel 229.
