Description
BACKGROUND OF THE INVENTION
The present invention relates generally to display containers and
more particularly to improved mechanism for opening and closing
such containers.
In the packaging industry, it has for some time been desirable to
provide a pleasingly aesthetic package that could be utilized as a
display container for merchandising the articles enclosed therein.
Various types of packaging devices that are capable of being used
as a display container are presently in existence.
However, because of the extensive competition in various areas of
merchandising, manufacturers are constantly striving to gain a
competitive advantage not only by producing more desirable type of
articles, but also by encasing the articles in more attractive and
durable containers.
SUMMARY OF THE INVENTION
The present invention provides an extremely attractive and durable
container that can be utilized for shipping merchandise from a
manufacturing operation to a retail establishment and also can be
utilized for displaying the article to prospective purchasers. The
container includes a cover that is movable between opened and
closed positions by an actuator which also positively holds and
locks the cover in either of the two positions relative to the
container. The article to be displayed -- as, for example, a
wristwatch -- is secured to the inside of the cover in a manner
that will bring the article into view when the cover is swung to
its open position.
In the illustrated embodiment of the invention, the container cover
is pivoted on a main body and is movable between open and closed
positions by an actuator that is recipprocally supported on the
main body of the container. A pair of surfaces are respectively
defined on the actuator and the cover that cooperate with each
other (1) to lock the cover to the body in either a closed or an
open position, and (2) to move the cover between closed and open
positions while the actuator is moved between extreme positions.
For this purpose, the cooperating surfaces have drive means along
an intermediate portion of the cooperating surfaces and locking
means on opposite ends of the drive means. The locking means
include a portion of each of the surfaces on the cover and the
actuator that are in extended contacting engagement with each other
when the actuator and the cover are in either of the extreme
positions. IN addition, if desired, additional locking means in the
form of a projection and recess respectively defined on the
actuator and the cover provide additional locking of the cover
relative to the container in either of the two extreme
positions.
In one embodiment, the actuator is an elongated member that is
reciprocated along a planar path on the container body and has a
substantially flat or planar surface acting as one of the
cooperating surfaces referred to above. The other cooperating
surface is carried by the cover, and is substantially U-shaped in
configuration and has planar end portions that are in extended
engagement with the planar surface of the actuator when the cover
is in either of the extreme positions. The drive means includes a
rack and pinion arrangement located respectively on the
intermediate portion of the planar surface of the actuator and on
the intermediate portion of the surface on the cover.
In an alternative embodiment, the actuating member is reciprocated
by being pivoted about a fixed axis on the main body, with the
cooperating surface on the actuator being arcuate or convex in
configuration. In this embodiment, the end portions of the surface
on the cover are concave and have a configuration corresponding to
the configuration of the convex surface. The drive means in this
embodiment is again in the form of a rack on the actuator, with a
pinion located between the elongated concave surfaces on the
cover.

DETAILED DESCRIPTION
While this invention is susceptible of embodiment in many different
forms, there is shown in the drawings and will herein be described
in detail two specific embodiments, with the understanding that the
present disclosure is to be considered as an exemplification of the
principles of the invention and is not intended to limit the
invention to the embodiments illustrated.
FIG. 1 of the drawings shows a container 10 consisting of a main
body 12 and a cover or tray 14. As best seen in FIGS. 2 and 3, the
cover is pivotally supported by a pair of pivot projections or pins
18 (only one being shown) that are rotatably supported in recesses
20 (one being shown) defined in the end walls of the container body
12. As shown in FIG. 2, the pins 18 project from opposite ends of
the cover 14 at a location centrally between the two side edges 22
of the cover. Thus, the cover can be pivoted from a closed position
shown by the phantom line in FIG. 2 to an open position that is
180.degree. from the closed position.
According to the present invention, the means for pivoting the
cover 14 relative to the main body 12 of the container 10 is
capable of (1) moving the cover between the two extreme positions,
and (2) maintaining the cover in either of the open or closed
positions.
For this purpose, an actuator 30 is supported for reciprocal
movement on the main body 12 of the container. IN FIG. 2, the
actuator 30 includes an elongaged main body portion 32 that has an
actuating lug 34 extending therefrom and received through an
elongated slot 36 in the end wall of the container 12. The actuator
30 is guided for reciprocation between extreme positions along a
substantially planar path by an elongated rib 38 intergral with the
end wall of the container and received in an elongaged recess 40
defined in the main wall 32 of the actuator 30. In addition, the
upper portion of the actuator is supported between the container
body and the cover and has an elongated slot 39 through which the
pin 18 extends.
The actuator 30 further includes a rack 42 integral with the main
body 32 and the rack has an elongated or flat surface 43 thereon. A
plurality of gear teeth 44 are defined on an intermediate portion
of the surface 43 and the gear teeth extend above the elongated
planar or flat end portions 46 and 48 of the elongated surface
43.
The means for pivoting the cover further includes a pinion element
50 supported on the pivot means or pin 18 and integrally formed as
part of the cover 14. The element 50 has a continuous substantially
U-shaped surface 52 on the periphery thereof with gear teeth 54 on
an intermediate arcuate portion of the surface and substantially
flat planar end portions 56 and 58.
In the closed position for the cover 14, the planar or elongated
end portions 48 and 58 of the surfaces 43 and 52, respectively are
in extended contacting engagement with each other to provide a
locking means for maintaining the cover in the closed position. In
order to open the cover, it is only necessary to grasp the lug 34
and slide the lug along the elongated slot 36 in the direction of
the arrow shown in FIG. 2. During the initial movement of the
actuator, the planar end portion 48 of the surface 43 will be slid
relative to the cooperating elongated planar end portion 58 of the
surface 52 on the pinion element 50. However, as the intermediate
portion of the surface 43, with the projecting gear teeth 44,
approaches the pinion element 50, the first of the gear teeth will
engage the gear teeth 54 on the pinion element 50 of cover 12 and
cause a pivotal movement of the cover about the pivot pins or means
18.
Since the intermediate portion of the surface 52 is substantially
semi-circular in configuration and has a plurality of gear teeth 54
thereon, the meshing engagement of the teeth 44 and 54 will cause
substantially 180.degree. of pivotal movement of the cover as the
actuator 30 is being moved to the left as viewed in FIG. 2. When
the cover has been rotated 180.degree., the surface 56 on the cover
will be in extended engagement with the surface 46 on the actuator
to define the second locking means adjacent the opposite end of the
intermediate portion of the cooperating surfaces 43 and 52 to
maintain the cover in the open position.
From the above description, it will be appreciated that the
surfaces 43 and 52 are cooperating surfaces on the actuator and the
cover, respectively, and the gear teeth 44 and 54 define drive
means on an intermediate portion of the cooperating surfaces for
moving the cover between open and closed positions in response to
reciprocal movement of the actuator relative to the cover. In
addition, the flat, planar end portions 46 and 48 on the surface 43
and the flat planar end portions 56 and 58 on the surface 52 define
elongated cooperating surface portions that are in extended
engagement when the actuator and cover are in either of the extreme
positions to positively maintain the cover in the respective
positions. Thus, the actuating means for the cover may broadly be
termed a rack and pinion arrangement with locking surfaces on
opposite ends of each of the rack and the pinion.
While the cooperating locking surfaces 46, 56 and 48,58 provide a
locking means for maintaining the cover in either position, it may
be desirable in certain instances to provide a more positive
interlock between the cover and the main body of the container for
either of the two positions for the cover.
Thus, according to another aspect of the invention, the first and
second locking means further includes a pair of projections 60 and
62 on the actuator adjacent opposite ends of the elongated surface
43 and means, in the form of a recess 64, on the pinion element for
receiving one of the projections when the actuator and the cover
are in either of the extreme positions. The cooperating projections
and recess provide a positive interlock between the cover and the
actuator when they are in the extreme positions, while the initial
movement of the actuator will cause the projection 60 or 62 to
slide out of the recess 64 and allow subsequent pivotal movement of
the cover and element in response to further sliding or reciprocal
movement of the actuator.
A slightly modified embodiment of the present invention is
disclosed in FIG. 4. Since the various elements forming the
actuating means are substantially identical, like reference
numerals have been applied with the addition of 100 to each of the
reference numerals.
In the modified embodiment, the actuator 130 has a main body 132
with a tapered portion 170 tapering substantially to a point
received in a recess 172 formed in an upwardly extending projection
174 on the lower wall of the main body 112. The elongated surface
143 is substantially arcuate in configuration and defines a rack
having the gear teeth 144 along an intermediate portion of the
surface 143 with the opposite ends 146 and 148 being convex in
configuration. The elongated surfaces 156 and 158 on the pinion
element 150 are concave in configuration and correspond to the
configuration of the convex surfaces 146 and 148.
In the modified embodiment of FIG. 4, the projections 160 and 162
are integral extensions extending upwardly above the elongated
surface 143 adjacent opposite ends thereof and cooperate with two
recesses 164 defined in the remaining edge of the pinion element
150. Since the operation of the modified embodiment of the
invention shown in FIG. 4 is identical in connection with that
described in FIG. 3, it is believed that no description of the
operation is necessary.
While two recesses 164 have been shown in connection with the
embodiment of FIG. 4 for receiving the projection projections 160
and 162, it will be appreciated that the projections may be located
and arranged as shown in FIG. 5 where a single recess 164a can
receive either of the projections 160 or 162.
The present display container provides a sturdy container which can
readily be held in a closed position for shipment and which can be
stored in any retail store in a closed position. Whenever it is
desired to display the contents therein, the merchant need only
manipulate the lug or lever to open the container and expose the
contents supported in the cover.
It should be noted that while the present invention has been
described in connection with a container where the cover supports
the contents and is rotated substantially 180.degree. to expose the
contents in the cover, various modifications are considered within
the spirit of this invention. For example, the cover could readily
be pivoted adjacent one of the edges 22 and rotated approximately
90.degree. between the closed and open positions. With such a
modification, the elongated surfaces 56 and 58 on the element 50
would be located at a 90.degree. angle relative to each other,
while the intermediate portion 54 would encompass approximately a
90.degree. segment with the gear teeth defined thereon.
