any suitable means.
The locking members 32 are longer than the
width of the cover or closure 20 so that the bev
eled ends 38 extend completely into the groove
broken to show a groove and one of the seals 55 28 when the members 32 are positioned by cor
ping case according to my invention, partially
responding, adjacent stops 40 transversely of the
removal from the stop and, locking members so
that the container can be opened and the con
cover or closure (as illustrated in Fig. 1), the
stops arranged on the closure or cover relatively
tents removed, whereupon the container may be
to the locking members to accomplish this.
For convenience in the manufacture of the corn
tainer, the locking grooves 28 are arranged along
the sides l6 extending from one end of the con
tainer or case to the other end thereof, though
it will be understood that these grooves need only
be long enough and properly spaced to permit
the entry therein in looking position of the bev
eled ends 38 of the locking members 32.
In operation, after the box or shipping is
packed and the cover or closure locked in posi
tion by swinging the beveled ends 38 of the mem
bers 32 into the groove 28, whereupon’ the case or
container will not be opened unless the members
are purposely moved into a position such as illus
trated in Fig. 5.
In order to prevent tampering with the case
and unauthorized removal of its contents during
transit, I provide means for looking a member 32
to a stop 40, in the container closing position il
lustrated in Fig. 1.
A comparatively inexpensive construction to
accomplish this is to provide an opening 42 in
each stop 48 and a corresponding opening 44 in
each member 32, the openings being brought into
parallel alignment upon bringing home against
its corresponding stop 40 a member 32. A catch
member 46, such as a U-shaped staple, one leg
48 of which is arranged in the stop member open
ing 42 and the other leg 50 of which is arranged
in the aligned opening 44 of the corresponding
locking member 32, prevents these members from
being moved into the position illustrated in Fig.
5, whereat the ends 38 have been moved out of the
grooves 28 to thereby permit removal of the cover
or closure 20 from the container or case.
This catch member or lock 46 may then be
sealed as by the metal or paper seal 52, which
covers and holds the catch member or look in
position and which seal is preferably cemented
to the stop and locking members. Should the
seals be removed or in any way broken or dam
closed, as described, the catch member or look
rescaled so that it will not be lost and the con
tainer returned to the shipper for reuse.
It will now be recognized that I have provided
a shipping container or packing case which will
in no way be damaged when it is opened to re
move its contents, even though it had been sealed
to prevent tampering therewith or unauthorized
removal of its contents, so that it may be used
again and again, as desired, making possible for
its construction heretofor unused relatively ex
pensive and durable materials.
While I have described in speci?c detail the
construction of an embodiment of my invention,
I do not intend to be limited thereto but intend
to claim the invention as broadly as the following
claim and the state of the prior art will permit,
since changes in the construction details thereof
will now readily occur to those skilled in the art.
I claim:
A shipping case comprising a bottom, end walls,
side walls and a removable closure therefor, said
side walls having grooves therein, locking mem
bers pivotally secured to the closure, stop mem
bers ?xed to the closure and extending sub
stantially at right angles to the grooves upon
arranging the closure in the case, each of said
locking members to be swung about its pivot into
locking position against a stop member with the
ends or” the locking member inserted in a said
roove, each of said stop and locking members
having holes therein, the mouth of the hole in a
stop member lying in the same horizontal line as
the mouth of the hole in the locking member upon
bringing the locking member against a stop mem
ber, a U-shaped member, the legs of which com
pletely and removably extend into a hole in the
stop member and into the hole of the correspond—
ing locking member, the element of said U-shaped
member connecting the legs thereof being posi
tioned on and against the top of the stop mem~
ber and corresponding locking member and a ?at
sealing member secured to the surface of the stop
member and corresponding locking member and
extending partially thereover to partially cover

possible tampering with the contents that had
