CONTAINER WITH MEANS FOR LOCKING THE LID
Abstract
A container having means for easily locking and unlocking the
lid of the container. The lid sits on a ledge of the container
body. A side wall of the container body extends above the lid and
has a relief which extends above the lid also. A locking tab on the

Claims
What is claimed is:
1. In a container having a body and a lid, the improvement
comprising
a ledge on said container body, said lid resting on said ledge,
said lid being hinged to said body,
a container wall extending above said lid,
a relief in said upstanding wall, said relief extending above said
lid,
a locking tab hinged to said lid and extendable upwardly into said
relief to lock said lid to said body.
2. The container of claim 1 in which the side edges of said lid are
hinged to said body and said lid is divided longitudinally.
3. In a container having a body and a lid, the improvement
comprising
a ledge on said container body, said lid resting on said ledge,
stacking cleats on said container body extending above said
lid,
a relief in the inner face of said stacking cleat, said relief
extending above said lid,
said lid being relieved at said stacking cleat, and
a locking tab hinged to said lid from the inner edge of said lid
relief and extendable upwardly into said stacking cleat relief to
lock said lid to said body.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
Means for locking a lid on a container.
2. Description of the Prior Art
Kieckhefer U.S. Pat. No. 2,622,785 which issued Dec. 23, 1952,
George U.S. Pat. No. 2,736,487 which issued Feb. 28, 1956, and
Reynolds U.S. Pat. No. 3,095,137 which issued June 25, 1963
disclose various locking combinations for lids.
In Kieckhefer a spring wire on an outside flap of the lid is biased
into an aperture on the outer side wall. Reynolds discloses a
downwardly extending flange on the lid which extends into the
container. It has locking tabs 32 which fit into apertures on the
inner face of the container. George discloses dovetailing segments
on the top of the end walls and the ends of the lid. Two different
styles are disclosed.
BRIEF SUMMARY OF THE INVENTION
Means for easily locking and unlocking the lid of a container. The
lid sits on a ledge of the container and has locking tabs which fit
into a relief on a side wall of the container body. The relief and
the side wall extend above the lid. The locking tab extends
upwardly into the aperture and frictionally engages the top and
back of the relief to lock the lid in place. The tab may be pulled
from the aperture to unlock the lid.

DETAILED DESCRIPTION OF THE DRAWINGS
The container 100 is formed by folding the body 40 around the end
panels 20.
The end panels are formed from end wall blank 10. The blank, FIG.
3, is divided by a single score line 11 and double score line 12
into a center panel 13, an inner panel 14 and an outer panel 15.
Glue stripes 16 on the inner and outer panels 14 and 15 adhere
these panels to the center panel 13 to form the end panel 20.
The end panel 20 has stacking cleats 21 on its upper edge, and
reliefs 22 on its lower edge for reception of the stacking cleats
of the container below. The cleats are formed by the tabs 23, 24,
and 25 on panels 13, 14, and 15 respectively. Two of these tabs--24
and 25--are formed by reliefs 26 at the edges of the blank and
aperture 27 in the center of the blank. The stacking cleat reliefs
are formed by the aperture 28 in panels 13 and 14, and the relief
29 in the edge of panel 15. The opposing edges of the apertures 28
and the edge of the relief 29 are aligned in the end panel 20 to
form the relief 22.
The aperture 30 in both the tab 24 and its associated inner panel
14 forms a locking relief in the end wall. The tab 23 on the inner
panel 13 is the back of the locking relief 30.
The container body 40 is formed from blank 41, divided by
longitudinal score lines 42 and 43 into a bottom panel 44, side
walls 45 and lid panels 46. The body 40 is attached to the end
panels 20 by the bottom flanges 47 and side flanges 48 which are
hinged to the bottom panel 44 and side walls 45 by score line 49.
Apertures 50 in the bottom panel 44 are aligned with the cleat
reliefs 22 in the end walls.
An inner liner 60 may be provided. It is formed from blank 61. The
longitudinal score lines 62 divide it into a bottom panel 63 and
side walls 64. The apertures 65 in the side walls 64 are aligned
with the apertures 51 in the side walls 45 of the container body
and the reliefs 66 of the liner are aligned with the apertures 52
of the body 40. These apertures are provided in produce containers
to allow the passage of air through the container.
In the formed container the lids 46 are bent downwardly around
score lines 43 until they rest on the ledges 70 formed by the upper
edge of the end panels. The lids have reliefs 71 which accommodate
the stacking cleats 21. A locking tab 72 is hinged to the inner
edge of the relief 71 by score line 73. When the lid is closed the
locking tab 72 is placed in the locking relief 30 and frictionally
engages the relief top and back to hold the lid in place. The lid
may be opened by pulling the tab 72 from the aperture.
Although the box has been described in terms of a lid hinged to the
side walls it can also be used for a removable lid.
