Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to greeting cards and particularly
to musical greeting cards. More particularly, a musical greeting
card is described which is of modern and durable construction and
relatively inexpensive to manufacture.
2. Description of the Prior Art
The greeting card industry has enjoyed rapid growth in recent
years. It is well known that there is a market for almost any type
of greeting card, whether it is sentimental or humorous, or simply
to mark an occasion.
In order to satisfy the market and to provide a competitive product
it is necessary that greeting cards have the advantages of modern
and durable construction. Modern construction is necessary so as to
take advantage of the cost reduction aspects of newer materials and
processes. Durable construction is an important advantage when it
is considered that greeting cards are more often than not
transported via mail and parcel services and frequently become
memorablia saved through the years, with both events occurring
under less than optimum conditions.
Prior art greeting cards of the type described have not had the
aforenoted advantages. They have generally been of non-durable
materials with minimum structural attributes and a relatively high
degree of expendibility.
SUMMARY OF THE INVENTION
This invention contemplates a greeting card including a unitary
member which is vacuum formed from a suitable plastic. A natural
hinge separates front and back covers whereby the card is opened
and closed. The inside area of the back cover includes an
open-topped box like member and the inside area of the front cover
includes a platform member which is received in interference fit
relation by the box like member to maintain the card closed. The
platform member supports a resiliently biased decoration which is
compressed when the card is maintained closed and pops-up when the
card is opened as by pressing against the interference fit. A music
box or like mechanism is arranged with the box-like member and
includes a protruding actuating arm which is released when the card
is opened to engage the mechanism. Decorative panels are supported
by the outside areas of the front and back covers.
One object of this invention is to provide a greeting card of the
type described which is of durable construction and is economical
to manufacture.
Another object of this invention is to provide a greeting card of
the type described which is formed from a unitary member having a
natural hinge separating front and back covers and for closing and
opening the card.
Another object of this invention is to provide means whereby the
front and back covers communicate in interference fit relation for
maintaining said covers closed.
Another object of this invention is to provide a resiliently biased
decorative member supported by the front cover and arranged to
pop-up when the card is opened.
Another object of this invention is to arrange a music box or like
mechanism so as to be actuated when the card is opened.
Another object of this invention is to provide decorative panels on
the front and back covers.
The foregoing and other objects and advantages of the invention
will appear more fully hereinafter from a consideration of the
detailed description which follows, taken together with the
accompanying drawings wherein several embodiments of the invention
are illustrated by way of example. It is to be expressly
understood, however, that the drawings are for illustration
purposes only and are not to be construed as defining the limits of

DESCRIPTION OF THE INVENTION
FIG. 1 show the greeting card of the invention as comprising a
unitary flexible plastic member 2 having front and back covers 4
and 6, respectively. Front cover 4 carries a platform 8 on its
inside surface and back cover 6 carries an open-topped box like
member 10 on its inside surface. Front and back covers 4 and 6 are
separated by a plurality of parallel, transversely extending
indentations or reductions in thickness, commonly referred to in
the art as strike lines and designated by the numeral 12.
Unitary member 2, including platform 8, box 10 and strike line 12,
is vacuum formed from a suitable plastic which may be of the
polycarbonate family. A material marketed by the General Electric
Co. under the trade designation "Lexan" is suitable for the
purposes described. Vacuum forming of plastics is a process well
known in the art. It will suffice to say for purposes of the
present invention that the process includes providing a form
corresponding to the desired end product over which a thin sheet of
the selected plastic is placed. Under appropriate conditions of
heat a vacuum is drawn, whereupon the plastic assumes the shape of
the form. The process is particularly adaptable for providing
shallow dish or tray-like members such as the present invention as
shown in the drawings.
When member 2, which is preferably about .015 inches thick in the
areas adjacent platform 8 and box 10, and which thickness is
reduced to about .012 inches at strike lines 12, is folded along
the strike lines a natural hinge at 14 is formed as shown in FIG.
2. It will now be understood that hinge 14 facilitates closing
member 2 whereupon platform 8 and box 10 are brought into alignment
as shown in FIG. 5 for purposes which will be hereinafter
described. Rather than use strike lines 12 to provide natural hinge
14, the desired result may be achieved by providing a continuous
transversely extending area 15 reduced in thickness to about .012
inches as best shown in FIG. 5.
Platform 8 and box 10 are dimensioned so that when member 2 is
closed through hinge 14 as shown in FIGS. 2 and 5, the platform
communicates with the box in interference fit relation. The
arrangement is such that slight hand pressure is effective for
snapping the platform and box together, whereupon the greeting card
of the invention is maintained closed as best shown in FIG. 6.
In this connection it is noted that front edge 10A of box 10 has
formed therein a groove or notch 16 as shown in FIGS. 1, 2, 6 and
7. It will be understood that when it is desired to open the
greeting card the finger or thumb of the viewer is inserted in
notch 16 for exerting a pressure to unsnap platform 8 and box 10,
with the card being thereupon opened by taking advantage of natural
hinge 14.
With further reference to FIG. 1, a bottom surface 10B of box 10
may carry a suitable greeting or message such as the seasonal
greeting which is shown, for purposes of illustration, in the
figure. Likewise, top surface 8A of platform 8 supports a suitable
decorative member such as, for purposes of illustration, an
artificial floral arrangement 18. Floral arrangement 18 is
resiliently supported by platform 8 and is arranged to pop-up when
the greeting card of the invention is opened as heretofore noted.
This feature of the invention will be more fully explained with
reference to FIGS. 3 and 4.
A music box or similar mechanism 20 is carried by box 10 as shown
in FIG. 1. Mechanism 20 is shown, for purposes of illustration, as
carried by upper edge 10C of box 10, it being within the scope of
the invention to carry the mechanism at any other suitable part of
the box as well as on platform 8. Mechanism 20 may be of the
commercially available miniature type which is inactive when arm 22
is depressed as by closing the greeting card of the invention as
heretofore noted, whereby the inside surface of cover 4 depresses
the arm. When the card is opened arm 22 extends and mechanism 20 is
actuated to emit an appropriate tune or sound as the case may be.
While mechanism 20 has been described as formed into box 10, an
alternate arrangement is to provide a recess along the edge of the
box, and into which recess mechanism 20 is snapped as will be
understood by those skilled in the art.
With reference to FIGS. 2, 5 and 6, the outside surface of covers 4
and 6 carry panel members 24 and 28. At least panel 28 may be
decorative or carry a suitable message as shown in the figures. The
panels may be cemented to the respective surfaces of the card
covers, or alternately, may be of a thermoplastic material and heat
sealed to said surfaces as will now be understood.
Returning now to the feature of the invention wherein decorative
member 18 is resiliently supported so as to pop-up when the card is
opened, FIG. 3 shows one embodiment of this feature. A plastic tab
30 about .012 inches thick is formed integral with platform 8 and
extends angularly therefrom in contilever fashion as shown in the
figure and normally supports member 18, which may be suitably
mounted to arm 30 as by cementing or the like, away from the
platform. With the greeting card of the invention closed as
heretofore noted, member 18 is received by box 10 and tab 30 is
biased when platform 8 nearly bottoms in the box to draw member 18
toward the platform. Upon opening the greeting card of the
invention, as by separating platform 8 and box 10 by using finger
notch 16, arm 30 and member 18 spring away from the platform so
that member 18, in effect, pops-up.
An alternate arrangement of this feature of the invention is shown
in FIG. 4 wherein a boss 32 is formed on platform 8. The boss
carries a conventional coil type spring 34 which may be in the boss
or subsequently assembled therein. The compression and extension of
spring 34 upon the closing and opening of the greeting card of the
invention as heretofore described provides the aforenoted pop-up
action.
It will now be seen that the invention as described satisfies the
objects hereunto set forth. The greeting card of the invention is
formed from a unitary flexible plastic member which has a natural
hinge arrangement for opening and closing the card. Platform and
box members carried on opposite sides of the card communicate in
interference fit relation to maintain the card closed, and a music
box mechanism is actuated upon opening the card as by separating
the platform and box members. A resiliently supported decorative
member is arranged to pop-up when the card is so opened. The
greeting card of the invention takes advantage of modern materials
and processes and is of durable construction and economical to
manufacture, and is thus a distinct improvement over greeting cards
of the type now known in the art.
Although several embodiments of the invention have been illustrated
and described in detail, it is to be expressly understood that the
invention is not limited thereto. Various changes may also be made
in the design and arrangement of the parts without departing from
the spirit and scope of the invention as will be understood by
those skilled in the art. For example, although the invention has
been described with platform 8 on cover 4 and box 10 on cover 6, it
is equally within the scope of the invention that the platform and
box be carried by the opposite covers, respectively.
