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.




An embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which:

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.
