STORAGE AND DISPLAY DEVICE FOR PACKING RINGS BACKGROUND OF THE INVENTION For many users and distributors of packing rings it is desirable to have a storage and/or display container for the same. Preferably the container should provide for storing various sizes of rings and with means for keeping the sizes, segregated. Moreover it is desirable to provide for any desired selection of sizes and with means to alter the selection at any time.

In previous containers for these purposes it has been difficult to provide convenient means for storing selective sizes of rings wherein the size selection may readily be altered. Moreover, such previous containers did not provide stable support forhinged sections when open.

SUMMARY OF THE INVENTION The present invention provides a storage and display device for packing rings in which rings of various sizes are mounted on pegs of corresponding sizes and the pegs are removably attached to a slotted support plate contained within a box. The attachment means for each peg includes an axial projection that extends through a slot in the support plate and a tongue that engages the underside of the support plate in one rotative position of the peg to prevent detachment of the peg until the peg is rotated to another position in which the tongue is aligned with the slot whereby it may pass therethrough.

The box includes a closure panel with a flat base to support the panel in an upright position and also includes a base panel upon which the support plate is mounted and the base panel is so hinged to the closure panel that it is coplanar with the flat base of the closure panel when the box is open to provide stability. The device is preferably made with two base panels hinged to a common intermediate closure panel so as to form a double box.

DESCRIPTION FIG. I is a perspective view of a double box form of the device with both boxes open.

FIG. 2 is an end view with one box open and the other closed.

FIG. 3 is a front view showing both boxes closed.

FIG. 4 is a partial cross section on lines 4-4 of FIG. 1 showing a peg in a rotative position in which it is locked in the box.

FIG. 5 is a view like FIG. 4 but showing the peg in a rotative position in which it may be removed.

FIG. 6 is a bottom end view ofa peg.

The device 10 includes an intermediate closure panel 11 having recesses 12, 13 on opposite sides thereof and separated by a wall 14. At its upper end the closure panel has a handle 15 by means of which the device 10 may be carried and at its lower end it has a flat base portion 16 attached to the main body portion ofclosure panel II by a web 17.

Hinged as at 21 to one side of closure panel 11 is a base panel 20. Another base panel 23 is similarly hinged to the other side ofclosure panel 11.

Base panel includes a bottom panel 22 and side panels 24, 25, 26 and 27. Spaced from bottom panel 22 is a support plate 28 that has a series of slots 29 therein. Support plate 28 is affixed to base panel 20 by cementing or any other convenient means.

A series of pegs 31 are removably attachable to support plate 28. These pegs may be of various diameters according to the diameters of packing rings that are to be mounted thereon. For example, FIG. 4 shows a peg 31 upon which O-ring packings 30 are mounted. The inside diameter of the O-rings is a close fit with the diameter of the peg and at its upper end the peg has a small bead 39 for retaining the O-rings. Being elastomeric, the O-rings can be readily stretched to pass over bead 39.

Each peg 31 has at its lower end a radially projecting annular flange 32, an axially projecting portion 33 and a tongue 34. As shown in FIG. 6, the axial projection 33 is preferably cylindrical with two flatted sides 36, 37. The cylindrical diameter is substantially the same as the width of slots 29 and the distance across the flats 36, 37 is somewhat less.

Tongue 34 has a width slightly less than the width of slots 29 and a length that is greater than the slot width. Tongue 34 is spaced from flange 32 a distance the same as or slightly less than the thickness of support plate 28. The pegs, as well as the other portions of the display device, are perferably made of molded plastic and tongue 34 will yield somewhat so that when it is spaced from flange 32 a distance slightly less than the thickness of support plate 28 it will yield or bend down slightly during rotation to the FIG. 4 position to receive sup port plate 28 between it and flange 32 and thus be frictionally held in such rotative position.

Flange 32 has a tab 35 radially projecting in the same direction as the lengthwise dimension of tongue 34 so as to indicate the orientation of tongue 34 when the peg is in position on support plate 28.

To attach a peg 31 to support plate 28. the peg is rotated until the lengthwise dimension of tongue 34 is the in the same directionas slot 29 and the tongue is then passed through the slot as shown in FIG. 5. The peg is then rotated so that the length dimension of tongue 34 is crosswise of the slot 29, as shown in FIG. 4. In this position the tongue is underneath portions of support plate 28 to lock peg 31 thereto and tongue 34 and flange 32 are frictionally engaged with support plate 28 to prevent inadvertent rotation ofthe peg to the release position.

As shown in FIG. 2, base portion 16 of closure panel II is located so that when either of base panels 20, 23 are opened to a horizontal position the bottom faces of such base panels 20, 23 are coplanar with the bottom face of base portion 16. This provides for stable positioning and support of closure panel II in its upright position when either of the base panels 20, 23 are in their horizontal or open position.

We claim:

I. A device for storing and displaying rings comprising a base panel, a support plate mounted on the base panel in spaced relation thereto, the support plate having a slot therein, a peg rotatably mounted on the support plate, the peg having a bottom surface in contact with the upper side of the support plate and having an axial projection extending through the slot, the projection having a laterally extending tongue of a length such that it engages the underside of the support plate to prevent removal of the peg from the support plate when the peg has a first rotative position relative to the slot, said axial projection in cross section having a dimension in one direction that is substantially the same as the slot width and such dimension is transverse to the slot when the peg is in said first rotative position whereby the projection engages the sides of the slot to prevent appreciable movement of the peg laterally of the slot.

2. The device of claim I in which the peg has an indicator means above the support plate to indicate the rotative position of the tongue.

3. The device of claim 1 in which the projection is of a length to provide a friction fit of the tongue against the underside of the support plate.
