Abstract
A storage case comprises a top portion and bottom portion adapted to abut each other in a closed position. A locking strip is mounted on an edge of the closed storage case. The top portion and bottom portion receive the locking strip. The storage case comprises formations receivable by said locking member such that said locking member and said storage case is in a locked position.
Description
This invention relates to a storage case. More particularly but not exclusively this invention relates to a lockable storage case for use with video tapes, compact discs, cassettes, computer games etc.
It is known to provide the cases of saleable items such as videos and compact discs with security devices to attempt to dissuade a potential thief from stealing. Such devices include plastic clips which may only be removed by a tool at the cashiers desk. These devices tend to be bulky and inhibit attractive display of the products.
A large number of retailers display only the cases of the products and store the actual products e.g. videos, in a secure location only accessible by store personnel. However, this requires more retail space and is time consuming when a customer wishes to make a purchase.
Another security device is a label which activates a security system when the product, to which it is applied, passes through the exit of the store. Such labels may, however, be easily peeled off the product.
EP-A-0 589 551 discloses a storage case having first and second leaves that are hingeable between a closed position in which portions of the leaves abut one another; and an open position. The leaves define a hollow interior of the storage case that is accessible, when the case is in its open position, for insertion and removal of articles.
The abutting portions of the leaves define a wall that includes a lock for locking the leaves in the closed position. The lock includes an elongate recess and a detachable locking member.
The abutting portions include grooves that are engageable by correspondingly shaped grooves formed on the locking member. Deflectable tabs, accessible via slots in the locking member, engage formations on the locking member when the latter is slid along the grooves to a locking position.
The arrangement of EP-A-0 589 551 suffers two main disadvantages.
The first is that the interengaging grooves on the abutting portions and the locking member mean that the locking member is exposed on the exterior of the storage case during use. Consequently it is easy for a thief to prise the locking member off the storage case, or otherwise render it inoperative.
Secondly the use of slots in the locking member, to provide access to the deflectable tabs, means that any unlocking tool must slide with the locking member as the latter is removed from the storage case. Consequently there is a risk of the unlocking tool moving out of engagement with the tabs before the locking member is completely unlocked.
EP-A-0 653 534 discloses another locking arrangement in which a U-shaped locking member encloses the abutting portions of the storage case.
The U-shaped member is in two parts, that are engageable with one another to define the U-shape. One of the parts of the U-shaped member includes formations that are engageable with deflectable tabs on the storage case.
The locking member of EP-A-0 653 534 suffers the same disadvantages as the EP-a-0 589 551 arrangement, because the locking member is exposed on the exterior of the storage case; and because an unlocking tool must pass through apertures in a moveable component in order to release the deflectable tabs.
In both the prior art arrangements the presence of deflectable tabs on the storage case complicates manufacture of the case and potentially shortens the life of the case.
According to the invention there is provided a storage case as defined in claim
1
.
Further, advantageous features of the invention are defined in the dependent claims.
In a storage case in accordance with the invention the locking member is releasable but it is intended that the locking member can only be readily released to unlock a locked storage case by use of a special tool. It is intended that such a tool will be available only to those authorised to have access to the contents of the storage case.

In the following description the embodiment of
FIGS. 1
to
10
do not form part of the invention but are described for purposes of illustrating some principles of the invention.
Referring to
FIGS. 1
to
4
, a storage case shown generally at
10
comprises a top portion
12
and a base portion
14
. The top and base portions
12
,
14
are formed as a single piece plastic moulding and are hinged about closed edge
16
. The storage case itself comprises an internal hollow rectangular storage portion (not shown) suitable for receiving a video tape.
The opening edge
18
of the case
10
is formed with a strip
20
. This strip
20
is formed with a dovetail portion
22
and is formed in two halves
21
,
23
. The top half
21
is attached to the top portion
12
of the storage case and the bottom half
23
is likewise attached to the bottom half
14
. In the storage case closed position as shown in
FIG. 1
both halves
21
,
23
of the locking strip
20
abut each other along their lengths. A removable L-shaped locking spline
24
is formed with a dovetail shaped slot
26
corresponding to the dovetail portion
22
of the storage case
10
.
Flexible locking clips
28
are formed on the inside of the L-shaped locking spline
24
. These locking clips
28
are adapted to be securely fitted within corresponding slots
30
.
In use the locking spline
24
is slid onto the locking strip
20
via its open end
32
and the dovetail slot
26
and portion
22
. Once the locking strip
24
is in place the locking clips
28
are press fitted into the receiving slots
30
to provide secure location of the spline
24
on the storage case
10
.
Once the locking strip is in its secured position, the contents of the case are not accessible unless the strip
24
is removed by the use of tool adapted to fit into the slots
30
and push the clips
28
out of the slots
30
hence removing the locking strip
24
. Such a tool (not shown) would, in use, only be available, for example, to the cashier.
A second embodiment is shown in
FIGS. 4 and 5
of the drawings. Referring to these drawings, storage case
10
comprises an opening edge
18
. This edge
18
is formed with a locking strip
33
formed in two portions
34
,
36
. Top portion
34
is mounted on the top opening half
12
of the storage case
10
and lower portion
36
is formed on the bottom opening half
14
. When the storage case is in the closed position the halves of the locking strip
33
abut each other.
Locking strip
33
is formed with a groove
38
in its top portion and a groove
40
formed in its bottom portion. These groves are shaped so as to be capable of receiving corresponding U shaped portions
44
,
46
of locking spline
42
. Locking spline
42
is formed in two halves
48
,
50
. Each half
48
,
50
is formed with a flexible locking clip
52
.
In use each half of the spline
42
is positioned over a different end of the strips
32
. The two halves are pushed together until the flexible locking clips
52
are securely retained in corresponding locking slots
54
. The locking spline halves may only be removed by use of a tool (not shown) formed to locate in locking slots
54
to push the clips
52
out of position.
Referring to
FIGS. 6
to
8
a storage case
10
again comprises top and base portions
12
,
14
. Opening edge
18
is formed with a number of L shaped clips
56
. These clips
56
are alternately mounted on the opening edges of top and bottom halves
12
,
14
of the storage case
10
.
A locking plate
58
comprises two locating walls
60
and a number of rectangular formations
62
. Each formation
62
comprises a triangle shaped tooth
64
each shaped to be received in corresponding slots
65
formed in clips
56
. In use the locking plate is slid onto the opening edge of the storage case, over the slips
56
. The teeth
64
are located in their corresponding slots
65
in a snap fit operation. Once in position on the storage case
10
the locking plate
58
forms a neat flush fit with the video storage case
10
.
The locking plate
58
, once in position on the storage case
10
, may only be removed by depression of the teeth
64
using a suitable removal tool (not shown).
Now referring to
FIGS. 9 and 10
a storage case
10
is formed with a number of L shaped clips
66
. At one end of the opening edge
18
of the storage case, locating members
68
are formed. These enable the locking plate
70
to be slit onto the storage case. Locking plate
70
is formed with a number of teeth
72
, corresponding to the number of clips
66
. The locking plate
70
is also formed with two flexible clips
174
.
In use the locking plate
70
is slit onto the opening edge of the storage case and each tooth
72
is located behind a corresponding L shaped clip
66
. The flexible clips
174
slide over the locating members and position the locking plate in a snap fit type operation.
Once the locking plate
70
is in position on the storage case
10
, the flexible clips
74
abut the locating members
68
thus preventing movement of the locking plate in a direction parallel to the edge
18
of the storage case
10
. The teeth
72
abut their corresponding clips
66
thus preventing the locking plate from being removed in a direction perpendicular to edge
18
. Thus removal of the locking plate is difficult without the use of a spacial tool to depress flexible clips
174
.
Now referring to
FIGS. 11
to
13
, storage case
10
according to the invention comprises a top portion
12
and a base portion
14
. The opening edge
18
of the storage case
10
is formed with a moulded end strip. This end strip is formed in two halves
74
,
76
. When the storage case
10
is in the closed and unlocked position as shown in
FIG. 11
the two halves
74
,
76
abut each other to form a hollow section
80
. Each half comprises a number of slots
78
and an opening cut out portion
82
to provide easy access for a thumb or a finger when opening. Slot
80
is formed to receive locking member in the form of plate
84
as shown in FIG.
12
. Locking plate
84
is formed with a number of teeth
86
.
In use the locking plate
84
is slid into the opening
80
of a closed storage case
10
thus ensuring the locking plate
84
cannot be withdrawn without use of a special tool. Teeth
86
are located within their corresponding slots
78
thus ensuring the case
10
remains in a closed position. The locking plate
84
may be removed by depression of the teeth
86
from their slots by use of a suitable tool An example of a suitable tool
88
is shown in
FIGS. 14 and 15
. A locked storage case with the locking plate
84
in position is shown in FIG.
13
.
When removing the locking plate all the locking teeth
86
are depressed simultaneously by the action of protrusions
90
of the locking tool. Thus the teeth
86
disengage from the case
10
. The locking plate
84
may be withdrawn longitudinally through aperture
92
of the locking tool
88
and the protrusions
90
fill the slots
78
of the storage case.
Advantageously the positioning of the locking plate over one edge of the storage case prevents access unless by use of a release tool. Thus contents of the storage cases are provided with improved security. The locking plates
84
are formed as splines engaging with tabs
93
positioned on both sides of the storage case hence preventing access to the storage case
10
without the use of such a special tool to depress relevant formations of each embodiment of the invention. It is also envisaged that the storage case and locking mechanism of the present invention may be suitable for use as a tamper proof “evidence” case for criminal investigation work.
