ADVERTISING SHEET CARRIER
Abstract
A resilient card has upper and lower margins spaced to fit
snugly into the upper and lower flanges of a price tag channel in a
merchandising center. It serves to support a pack of detachable
advertising sheets. Its mid portion is anchored to the channel by a
strip of pressure sensitive adhesive which prevents the card from
flexing sufficiently to permit its anchored margins to escape from
the flanges.

engagement in the channel, the pack of sheets having a backing
element connected with said card independently of said tab.
6. A device according to claim 5 in which the tab is integrally
connected at its upper portions to the card and has its side and
bottom end portions severed from said card along lines within the
card area, the backing element being connected with the card below
the lower margin of said tab.
7. A device according to claim 1 in which the adhesive means
comprises a strip of pressure-sensitive adhesive extending across
the card and provided with a removable protective strip.
8. A device according to claim 7 which comprises a severed section
of an elongated assemblage of a plurality of like devices on which
said adhesive strip and protective strip extend substantially
continuously.
9. The combination with a price tag channel having a central
generally vertical web and upper and lower flanges spaced by said
web, of a display device having a resiliently flexible supporting
card provided with upper and lower margins engageable behind said
flanges and spaced more widely than the clearance between said
flanges and adapted to pass between said flanges for insertion and
removal only when said card is flexed, said card having an
intermediate adhesive portion in adhesive connection with the web
of said channel, such connection resisting the flexing of the card
and the card being sufficiently stiff to support the device when
unflexed, the said connection being substantially free of the
weight of said device.
Description
BACKGROUND OF INVENTION
It has been quite common to mount packs of advertising sheets on
supporting cards which are mounted adhesively on the edges of
display shelves. In general, the support for the cards and the pack
of sheets has been provided in whole or in part by adhesive
connection to the shelf or price tag channel. Such adhesive
connections tend to yield progressively over a period of time. The
instant device is regarded as an improvement because it relies
primarily on the stiffness of the card itself to provide the
support.
SUMMARY OF THE INVENTION
A resiliently flexible card on which a pack of advertising sheets
is mounted can be flexed for insertion behind the flanges of a
price tag channel and has means for adhesive connection with the
channel. The dimensions preclude insertion or removal of the card
without flexing it to bring its margins closer together than the
clearance between flanges. The adhesive has the primary or sole
function of holding the card against flexion. Reliance is placed on
the stiffness of the card to provide the necessary support for the
pack. In normal use, the adhesive is not subject to tension but
resists solely an outward flexion as distinguished from a bias
exerted vertically.
DESCRIPTION OF DRAWINGS
FIG. 1 is a view in front elevation of a card and pack embodying
the invention, portions of an adjacent pack being fragmentarily
illustrated.
FIG. 2 is a view in side elevation of the card and pack illustrated
in FIG. 1.
FIG. 3 is a view fragmentarily showing a shelf and price tag
channel in vertical section with a card and pack illustrated in
side elevation, the card being shown flexed for its attachment to
the channel.
FIG. 4 is a view similar to FIG. 3 showing the completed attachment
of the card to the channel.
DETAILED DESCRIPTION
It is conventional to mount a price tag channel 6 on the front edge
8 of a shelf 10. The channel 6 usually comprises a convoluted
central web 12 and marginal flanges 14 and 16 which are folded
toward each other.
A relatively stiff but thin and resiliently flexible card 20 is
adhesively attached to a pasteboard back 22 for the pack 24 of
advertising sheets 26, these being connected with each other and
with the back 22 by a layer 28 of glue.
Such cards have commonly been joined by a pressure-sensitive
adhesive either directly to the shelf or to the price tag channel
6. Since the price tag channel usually has a transversely
convoluted wall 12, the adhesive is usually coextensive with the
card or the like which carries the pack of sheets. If the weight of
the pack of sheets is sustained solely by such adhesive, the
adhesive tends to yield over a period of time and cannot,
therefore, be depended upon to provide continued support.
According to the present invention, the supporting card 20 has
upper and lower marginal edges 30 and 32 which are so spaced as to
fit snugly into the respective flanges 14 and 16 as shown in FIG.
4. The lower edge 32 may be made coextensive with the length of
card 20 but in the preferred construction the lower marginal edges
32 are provided by one or more tabs 34, three being illustrated in
FIG. 1. These tabs may optionally have hinge portions 35 connecting
them with the rest of the card.
The spacing of the upper and lower edges exceeds the clearance
between flanges 14 and 16 of the price tag channel. Consequently,
in order to engage edges 30 and 32 in the flanges 14 and 16, it is
necessary to flex the card or the tabs in the manner shown in FIG.
3. When the card and/or tabs is flexed, the edges will pass between
the flanges 14 and 16. When the card and/or tabs is flattened out
as indicated in FIG. 4, the edges are securely locked in flanges 14
and 16. All weight will then be supported by tabs 34.
The invention contemplates that the card and tabs will be anchored
in this flattened condition. For this purpose, a strip of
pressure-sensitive adhesive is provided at 36 on the back of the
card 20. As shown in FIG. 2, this is covered by a protective strip
38 which can be pulled off to expose the adhesive before the device
is mounted. As will clearly appear from comparison of FIGS. 3 and
4, the flattening of the card after the protective strip 38 has
been moved will cause the pressure-sensitive adhesive strip 36 to
adhere to the price tag channel 6.
The adhesive is not biased by the weight of the pack of sheets 24,
such weight being sustained entirely by that portion by the lower
margins 30 of tabs 25, or such other portions of card 20 as have
lower margins engaged in flange 14. The sole function of the
adhesive is to resist an outward flexing movement of the card 20
which might bring about the release of margins 30 and 32 from the
flanges of the price tag channel. Under these conditions, the
adhesive is not under tension and remains effective indefinitely
and the card provides adequate support for the pack of sheets until
all have been used.
At that time, manual flexing tension exerted on the card will
readily withdraw it from the channel 6, leaving the channel open
for insertion of a price tag or the supporting card for a
substitute pack of sheets.
As indicated in FIG. 1, devices embodying the invention can be made
in long series and subsequently severed into individual units A and
B by transverse severance as at 40.
