System and method for displaying, vending and controlling inventory of valuable articles such as pre-recorded videotape cassettes

In an area accessible to browsing customers, at least one multiple-compartment display rack is provided. Each cell in the display rack removably receives an open-ended transparent plastic envelope containing a display card preferably printed with photographics, artwork and verbal indicia unique to a particular valuable article or service which is potentially available. Filed in series with the display card so as to have an end which protrudes further from the envelope mouth than the display card are a number of cards (from one to a plurality) which are tokens of units of the particular article or service, plus an additional card. Each of the first mentioned cards contains on its protruding end a consumer instruction, such as "TAKE CARD TO REGISTER", and elsewhere on its body, the title of the particular article to service. The additional card bears as its flag a consoling legend, such as "SORRY I'M RENTED". At the check-out register, the card of the first type is exchanged for the actual boxed pre-recorded video cassette or other particular article or service, and each first-type card so exchanged may be temporarily placed as a token in the inaccessible-to-customers supply area for inventory control purposes, until the rented article is returned, a restocking inventory is taken, or the like. The display rack thus acts as a more compact analog of the inaccessible supply than would a display rack of empty boxes for the articles or the like.

BACKGROUND OF THE INVENTION 
It is a common practice in urban stores specializing in the sale of 
pre-recorded audio tapes, for the self-service display racks through which 
customers are invited to browse, to contain empty cassette boxes which 
boxes bear as an inner wrapper (if they are transparent), or as an outer 
label (if they are opaque), the, very album cover with which the 
publisher has supplied the pre-recorded audio cassette. Each album cover 
typically contains photographs and/or artwork and verbal graphics which 
are distinctive of the particular recording and not only act as 
informative material for the potential customers, but also permit 
potential customers to quickly pick out recordings which they have come to 
recognize by having previously seen the same album covers as reproduced in 
display advertising in newspapers and in other print and electronic media. 
Under the conventional system which usually pertains in such shops, the 
actual pre-recorded cassettes are stored out-of-sight, i.e. under the 
counter near the check-out register. The intending customer takes the 
empty but labeled box from the display rack and brings it to the register, 
where the store employee fills it with the respective cassette from the 
storage place, at the same time posting an inventory control entry, e.g. 
via the check-out register as the sale is made and/or by simultaneously 
removing to an inventoring site some token of the sold item from the 
storage place. 
While such a system is likely to be very acceptable for a store which is 
primarily devoted to sales of pre-recorded audio cassetes or the like, it 
is deemed to be impractical for stores in which selling space is at a 
premium, particularly but not necessarily where the merchandise is bulky, 
the store wishes to stock multiple copies of many of the items, and the 
items are being rented, leased or lent, rather than being sold. 
Although the invention which has been made for solving the drawbacks of 
available systems was particularly devised as a way of renting 
pre-recorded videocassettes from display racks accessible to customers in 
convenience stores, it should be apparent following absorption of the 
disclosure of the present invention, that it could be used in the vending 
of other articles (such as rental tools) and services (such as seating for 
events in a theater, arena or stadium). 
SUMMARY OF THE INVENTION 
In an area accessible to browsing customers, at least one 
multiple-compartment display rack is provided. Each cell in the display 
rack removably receives an open-ended transparent plastic envelope 
containing a display card preferably printed with photographics, artwork 
and verbal indicia unique to a particular valuable article or service 
which is potentially available. Filed in series with the display card so 
as to have an end which protrudes further from the envelope mouth than the 
display card are a number of cards (from one to a plurality) which are 
tokens of units of the particular article or service, plus an additional 
card. Each of the first mentioned cards contains on its protruding end a 
consumer instruction, such as "TAKE CARD TO REGISTER", and elsewhere on 
its body, the title of the particular article or service. The additional 
card bears as its flag a consoling legend, such as "SORRY I,M RENTED". At 
the check-out register, the card of the first type is exchanged for the 
actual boxed pre-recorded video cassette or other particular article or 
service, and each first-type card so exchanged may be temporarily placed 
as a token in the inaccessible-to-customers supply area for inventory 
control purposes, until the rented article is returned, a restocking 
inventory is taken, or the like. The display rack thus acts as a more 
compact analog of the inaccessible supply than would a display rack of 
empty boxes for the articles or the like. 
The principles of the invention will be further discussed with reference to 
the drawings wherein a preferred embodiment is shown. The specifics 
illustrated in the drawings are intended to exemplify, rather than limit, 
aspects of the invention as defined in the claims.

DETAILED DESCRIPTION 
FIG. 1 shows in schematic view a store 10 having a self-service sales area 
12 which is accessible to customers, e.g. through an entrance 14. The 
store 10 is shown further provided with a check-out counter 16 having a 
register 18 for recording sales and holding change and payments received 
from customers. The check-out counter 16 typically separates the sales 
area 12 from a clerking area 18' to which the customers do not have direct 
access. Typically, the check-out counter 16 contains or encloses a behind- 
or an under-counter area, some portions of which may be used for display, 
as at 20, and other portions of which, generally indicated at 22 may be 
used for storage which is accessible to the clerks but not to the 
customers. Out on the sales floor, shelving, racks, bins and the like, 
generally indicated at 24 are typically provided stocked with goods for 
sale for self-service shopping by customers, who select their intending 
purchases and take them to the clerk at the check-out counter 16. 
In practicing the present invention, the self-service sales area 12 
accessible to customers is provided with one or more display racks 26 
having cells 28 for display packets 30. 
Each cell 28 is so constructed as to be generally vertically-elongated, 
front-facially substantially unobstructed to view, upwardly open, and 
provided with a holding means which is structured to permit substantially 
unobstructed view of the contents of the cell throughout substantially the 
full height of the cell, or at least throughout a substantial portion 
thereof. For instance, the front wall, opposite sidewalls and bottom wall 
of the cell, as well as most of the perimeter of its upwardly open mouth 
may be formed by a molded sheet of transparent plastic material 32, molded 
with an integral out-turned flange 34 which is secured, as at 36, to the 
backing wall 38, which also forms the back of each cell 28 and the 
remainder of the perimeter of its upwardly open mouth 40. Although the 
display rack 26 is shown being a vertically sided unit that is mounted on 
a pedestal 42 for manual rotation about a vertical axis, it may be 
one-sided, banked, wall-mounted or provided similarly to virtually any 
display rack meant for displaying individually accessible visible cells to 
store customers or the like, e.g. of the types conventionally used for 
displaying packets of garden seeds, sewing notions, recipe and nutrition 
booklets, employee time cards and the like. 
Each cell 28 is shown removably containing a respective enveloped packet 44 
which corresponds to a specific model of article or service which is 
availabe for purchase (sale or rent) at the store. (For convenience in 
discussion, it will be assumed that the rack 26 relates to the rental of 
pre-recorded video cassettes, and the reader will be expected to 
generalize an understanding of the principles of the invention from this 
specific but non-limitative example.) 
A typical enveloped packet 44 is shown in front elevational view in FIG. 3, 
and an exploded perspective view of it is shown in FIG. 4. 
The unit 44 will be seen to include an upwardly open, generally flat 
envelope 46, typically constituted by front and rear sheets 48, 50 of 
transparent, flexible plastic material, e.g. polyvinylchloride, 
polyethyleneterephthalate or the like, thermally welded to one another 
along three corresponding edges, as at 52, so as to leave an upwardly open 
mouth 54 defined between unseamed upper edges 56, 58 of the sheets 48, 50. 
(Alternatively, either or both sheets could be made partly or wholly of 
opaque plastic material, in which case the display cards (to be described) 
could be fastened on the outside face or faces of these envelopes, rather 
than sleeved within them, with the result of perhaps making it more 
difficult to reuse the envelopes.) 
Within the envelope 46 are shown contained a front display card 60 and a 
rear display card 62 which, typically, are the very cards which the 
publishers of the pre-recorded video cassettes provide as front and rear 
display cards for the boxes in which their products are furnished to the 
store. Typically, a front display card contains a logo-type of vignette or 
still from the movie, play or other work on which the video is based, 
its title, the names of characters, actors, songs or the like which appear 
in the work, and often credits, the publisher's name and/or logo, a 
copyright notice and other symbols, e.g. indicating that the soundtrack 
has been processed by a particular branded technique, or that the work is 
encoded with captions visible on command for hearing-impaired or 
language-limited persons whose viewing sets are suitably equipped. 
Typically a rear display card contains other vignettes, graphics, a 
synopsis of plot, comments of critics, other information and logography. 
Use of a rear display card is preferred but not essential to practicing 
the present invention. When desired, use of the rear display card may be 
omitted. By preference, the pocket 64 provided by the envelope 46 is at 
least as deep as the front and rear display cards 60, 62 are tall, so as 
to minimise the chance that, contrary to plan, the intending customer will 
withdraw either of these cards from the envelope 46. 
In each full packet, sandwiched between the front and rear display cards 60 
and 62 is at least one specific article token card 66, the number of such 
cards corresponding identically to the total number of copies of the 
particular title of pre-recorded cassette or the like which the store 
presently has in its inventory, available to be rented out to customers. 
Each card 66 includes an upper end marginal portion which protrudes upwards 
out of the envelope, past the upper end of the front display card 60, by 
virtue of its being taller than the card 60, e.g. so as to display a 
horizontal band 68 which contains an inviting instructional command, e.g. 
TAKE ME TO THE REGISTER, and a protruding tab 70 which is subject to being 
easily grasped for pulling the respective token card 66 individually from 
the packet while leaving all else behind. By preference, the cards 60, 62, 
66 are made of sufficiently slippery-surfaced stock on their mutally 
facing surfaces as to make it easy for an untutored intending customer to 
withdraw only one card 66, as intended, while leaving all the other cards 
behind in the envelope 46. 
The enveloped packet 44 preferably further contains an additional, 
consolation card 72, which also protrudes above the upper edge of the 
front display card 60 and bears in an upper end band 74 a conciliatory 
message, e.g. SORRY, I'M RENTED. (In practice, the card 72 need not be a 
separate card, if the rear display card 62 is provided with an upper 
extension of its forwardly facing inner face 76 that is provided with the 
flag 74.) 
In use, each cell of the display rack is stocked with an enveloped packet 
44 containing a packet of cards relating to a specific pre-recorded video 
program as to which the store has at least one cassette available for 
rent. In most instances, the store will have one, two, three or four 
copies of that cassette available, so that in addition to the respective 
front display card 60, and the rear display card 62 (and/or the additional 
card 72, as explained above), the packet will contain, sandwiched between 
the aforementioned cards, the appropriate numbers of token cards 66. Each 
token card has printed on its body a title or stock number which will 
permit the store clerk to match it with a specific title or item. An 
intending customer will browse through the display rack, perhaps looking 
at several of the enveloped packets, perhaps temporarily lifting any of 
the enveloped packets, as a unit, out of the respective cells in order to 
look at the rearwardly facing outer faces of the rear display cards 62. 
Finally, the intending customer withdraws one or more TAKE ME TO THE 
REGISTER-flagged token cards bearing on the bodies the titles or stock 
numbers for corresponding specific movies he or she wants to rent and 
takes them to the clerk at the check-out stand (often along with other 
intending purchases such as milk, bread, soda and cat food), and goes 
through a familiar check-out process. In the course of this process, the 
clerk, upon reaching the token card or cards exchanges them for the 
respective actual cassette or cassettes held in reserve in the supply 
area, e.g. behind the counter at 80 that is inaccessible to the customer, 
Information about the customer and/or the transaction may be recorded on 
or attached to the card 66 which has been exchanged. Accordingly, as the 
system is in use, the display stand couples only with movies of which the 
store has one or more copies actually in stock, an invitation ("TAKE ME TO 
THE REGISTER") to the intending customer, and issues only in connection 
with movies of which the store temporarily has no copies in stock, an 
apology ("SORRY, I'M RENTED"). The display rack, in use, thus represents a 
precise, compact physical analog of what cassettes are in the supply area 
80. And the store's behind-counter file of exchanged cards 66 represents a 
precise, compact physical analog of what cassettes are presently rented 
out. The latter file is easily periodically checked in order to contact 
customers in regard to overdue rental returns. When a rented cassette is 
returned, the clerk may easily return the respective card 66 to the 
respective envelope 46 and the respective cassette to the supply area 80. 
As new cassettes are acquired and old ones are withdrawn from rental, 
packets and supplies are correspondingly updated, with the clear plastic 
envelopes being re-used to the extend feasible. 
It should now be apparent that the system for displaying, vending and 
controlling inventory of valuable articles such as pre-recorded videotape 
cassettes as described hereinabove, possesses each of the attributes set 
forth in the specification under the heading "Summary of the Invention" 
hereinbefore. Because it can be modified to some extent without departing 
from the principles thereof as they have been outlined and explained in 
this specification, the present invention should be understood as 
encompassing all such modifications as are within the spirit and scope of 
the following claims.
