Description




BACKGROUND OF THE INVENTION




1. Field of the Invention:




This invention in general relates to article containers, and more particularly, to an article container which can help prevent a contained article from being easily stolen.




2. Description of Related Art:




Discs, such as CDs or DVDs, are typically contained in a flat box when they are displayed in a shop for sale or rent. Conventional disc boxes, however would allow the contained discs to be easily stolen.




One solution to the foregoing problem is to adhere theft-warning magnetic tags to the boxes. One drawback to this solution, however, is that the thieves could nevertheless open the boxes and steal the contained discs.




In view of this drawback, there exists a need for a disc box that can help prevent the contained articles from being easily stolen.




SUMMARY OF THE INVENTION




It is therefore an objective of this invention to provide an anti-theft container that can help prevent contained articles from being easily stolen.




In accordance with the foregoing and other objectives, the invention proposes a new container structure. The anti-theft container of the invention includes a casing having an access opening for placing an article therein. Further, the anti-theft container includes a locking member which has a substantially L-shaped cross section with a blocking piece which can be pulled backwards covering the access opening of the casing, and a slidable member mounted on the casing, capable of locking the locking member in position to the access opening when being installed in position, and allowing the locking member to be pulled backwards from the access opening when not fixed in position. Moreover, the anti-theft container of the invention includes a structure which has no backwards pulling movement capable of preventing the readily-installed slidable member from being pulled backwards; and an unlocking piece capable of disengaging the readily-installed slidable member from the structure which has no backwards pulling movement when being inserted in position.




The anti-theft container of the invention can help prevent the article contained therein from being stolen. With the invention, the article contained in this anti-theft container can be taken out only by using a special unlocking piece held by the owner. The invention can therefore effectively protect the contained article against theft.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




In accordance with the invention, several preferred embodiments are disclosed in the following with reference to the drawings.




First Preferred Embodiment




The first preferred embodiment of the anti-theft container of the invention is disclosed in the following with reference to

FIGS. 1-3

.




As shown, the anti-theft container includes a casing A having a hollowed space defined by a top plate


2


, a bottom plate


3


, and two sidewalls


4


. The casing A is used to hold an article


100


which can be accessed via an access opening


1


.




The top plate


2


of the casing A is formed with a guide slot


6


on which a slidable member


7


is installed. The slidable member


7


is an integral body of an elongated piece


10


and two side walls


11


having inwardly protruded portions


12


. The guide slot


6


includes oppositely arranged upright walls


8


whose outer sides are formed with slits


9


in which the inwardly protruded portions


12


of the side walls


11


of the slidable member


7


can be fitted to allow the slidable member


7


to move along the top plate


2


of the casing A.




In the embodiment of

FIG. 1

, the slidable member


7


is mounted on the top plate


2


of the casing A; but it can also be mounted on the side wall


4


.




The anti-theft container further includes a locking member


13


whose cross-section is substantially L-shaped. The locking member


13


is installed on the top plate


2


where the slidable member


7


is installed. The locking member


13


is formed with a blocking piece


14


and a stopper


19


. The blocking piece


14


is normally positioned in such a manner so as to block the access opening


1


of the casing A to prevent the article


100


contained in the casing A from being taken out. The locking member


13


is formed with a peg


15


, and correspondingly, the top plate


2


is formed with a hole


16


to accept the peg


15


, allowing the locking member


13


to be fitted onto the top plate


2


by means of this peg-and-hole structure.




The slidable member


7


is formed with a protruded portion


17


on the front end thereof. As shown in

FIG. 2

, when the slidable member


7


is pushed to the extreme end, i.e., when it is entirely positioned on the top plate


2


, the slidable member


7


is stopped by the stopper


19


and its protruded portion


17


is engaged with the locking member


13


, thereby locking the locking member


13


in position.




As shown in

FIG. 3

, when the slidable member


7


is pulled backwards, it unlocks the locking member


13


, thus allowing the locking member


13


to be flipped up by the user's finger to draw the blocking piece


14


away from the access opening


1


of the casing A. This allows the user to take out the article


100


via the access opening


1


which the blocking piece


14


no longer blocks.




When the article


100


is put back into the casing A, the user can put the blocking piece


14


in front of the access opening


1


and then push the slidable member


7


forwards to lock the locking member


13


, and thus the blocking piece


14


, in position, as illustrated in FIG.


2


. This prevents the article


100


, contained in the casing A, from being taken out.




Since the user is required to simultaneously use one hand to pull the slidable member


7


backwards and the other hand to flip up the blocking piece


14


, the article


100


is difficult to remove. Therefore, the invention can help prevent the article


100


from being easily stolen.




Second Preferred Embodiment




As shown in

FIGS. 2 and 3

, the anti-theft container of the invention can be additionally formed with a hinged portion


20


in the back surface of the locking member


13


near the rear end of the locking member


13


. This hinged portion


20


can be, for example, a groove structure having a substantially V-shaped cross section.




The forming of the hinged portion


20


allows the locking member


13


to be more effortlessly flipped up to open the access opening


1


.




Third Preferred Embodiment




In accordance with the third preferred embodiment, the anti-theft container of the invention further includes the use of an unlocking piece


21


which is insertable into the receptacle portion


22


defined between the slidable member


7


and the top plate


2


. Further, the anti-theft container of the invention is formed with a structure


23


which has no backwards pulling movement and includes a plurality of upward-bent portions


25


on the top plate


2


and a plurality of corresponding stopper portions


24


on the slidable member


7


. When the unlocking piece


21


is entirely inserted into the receptacle portion


22


, it can flatten the upward-bent portion


25


of structure


23


which can not be pulled backwards, thereby allowing the slidable member


7


to be now pulled backwards.




With the foregoing structure, the slidable member


7


can be fixed in position on the top plate


2


by the structure


23


which prevents a backwards pull, so that the locking member


13


can be prevented from being flipped up to allow the article


100


contained in the casing A to be taken out. When the user desires to take out the article


100


, he can simply insert the unlocking piece


21


into the receptacle portion


22


so as to disengage the upward-bent portion


25


of structure


23


, which prevents a backwards pull, from the stopper


24


, thus allowing the unlocking piece


21


to be pulled backwards to allow the blocking piece


14


of the locking member


13


to be flipped up.




Fourth Preferred Embodiment




As shown in

FIGS. 1-8

in this embodiment, the anti-theft container of the invention is further formed with a stopper structure


31


in the receptacle portion


22


and a corresponding escaping structure


32


on the unlocking piece


21


.




The stopper structure


31


includes a protruded portion on the back side of the elongated piece


10


of the slidable member


7


and another protruded portion


31


in the middle of the back side of the slidable member


7


. The escape structure


32


on the unlocking piece


21


is a fork-like structure having a cutaway portion


33


separating a first finger


34


and a second finger


35


which is greater in length than the first finger


34


. The stopper structure


31


can be fitted in the cutaway portion


33


. During the course of inserting the unlocking piece


21


, it will be stopped by the stopper structure


31


. At this position, the first finger


34


has its front end abutted on the upward-bent portion


25


, while the second finger


35


has its front end urged against the upward-bent portion


25


, as illustrated in FIG.


6


. As a result, the stopper


24


is disengaged from the upward-bent portion


25


.




Further, as shown in

FIG. 7

, when the unlocking piece


21


is inserted in position, the escape structure


32


is substantially aligned to the two upward-bent portions


25


, and the front end of the first finger


34


urges against the upward-bent portion


25


to cause the upward-bent portion


25


to bend inwards. Moreover, the second finger


35


urges a bend inwards by the slanted surface


36


of the front stopper structure


31


and thereby an abutment on the upward-bent portion


25


. The unlocking piece


21


is preferably made of resin so as to provide elasticity to the first finger


34


and the second finger


35


to allow them to be easily bendable.




The forgoing provision can further help prevent the anti-theft container of the invention from being easily opened up.




Fifth Preferred Embodiment




Referring to

FIGS. 9

,


10


, and


11


, in this embodiment, the locking member


13


is integrally formed with the casing A. Further, two slits


41


are formed in the top plate


2


, with the part between these two slits


41


serving as the locking member


13


.




Moreover, a hinged portion


20


is formed near the rear end of the locking member


13


to allow the blocking piece


14


to be easily bendable when the blocking piece


14


is being pulled backwards.




The blocking piece


14


can be elongated so as to allow the blocking piece


14


to be urged by the article


100


when the article


100


is being pulled out of the casing A. This provision allows the locking member


13


to be pulled backwards without having to be pulled by the blocking piece


14


.




Sixth Preferred Embodiment




Referring to

FIGS. 12

,


13


,


14


, and


15


, in this embodiment, the locking member


13


can be restored to its original position when it is not pressed by the slidable member


7


. This can be achieved by forming the locking member


13


into a elastically curved shape.




As shown in

FIG. 12

, when the slidable member


7


is pulled backwards, the locking member


13


allows the blocking piece


14


to be withdrawn from the access opening


1


without requiring the user to do it by hand.




As shown in

FIG. 13

, when the slidable member


7


is moved forwards, it can urge against the locking member


13


and thereby flatten the locking member


13


into a biased state.




Alternatively, the restorable capability of the locking member


13


can be achieved by providing a spring


42


between the locking member


13


and the top plate


2


, as shown in

FIGS. 14 and 15

. Further, a plurality of crosswise grooves


44


can be formed on the back side of the locking member


13


, which can help reduce the resistance of the locking member


13


against the slidable member


7


.




Seventh Preferred Embodiment




Referring to

FIGS. 16

,


17


,


18


,


19


, and


20


, in this embodiment, the anti-theft container of the invention includes an insertion member


52


having an anchoring structure


55


. The insertion member


52


is insertable through a guide structure


51


formed on opposite ends of the access opening


1


. After being inserted in position, the insertion member


52


can not be pulled backwards due to its anchoring structure


55


being fitted in and stopped by the recessed portion


54


. A blocking piece


53


is provided at the front end of the guide structure


51


in front of the insertion member


52


for the purpose of preventing the article


100


contained in the casing A from being taken out through the access opening


1


.




As shown in

FIG. 18

, when the insertion member


52


is inserted into the guide structure


51


, the blocking piece


53


will be urged to close the access opening


1


; and meanwhile, the anchoring structure


55


is fitted into the recessed portion


54


, as shown in

FIG. 17

, whereby the insertion member


52


is prevented from being pulled backwards, allowing the blocking piece


53


to be fixed in position in front of the access opening


1


, thus preventing the article


100


contained in the casing A from being withdrawn to the outside.




To allow the insertion member


52


to be pulled backwards, the user can insert an unlocking piece


56


into the guide structure


51


. The unlocking piece


56


is an elongated piece having a tapered recessed portion


57


formed in the front end thereof. During the course of insertion, the tapered recessed portion


57


can first disengage the anchoring structure


55


from the recessed portion


54


and then push against the anchoring structure


55


to thereby push the insertion member


52


backwards. After the insertion member


52


is pulled backwards, the article


100


can then be withdrawn from the casing A.




Further, as shown in

FIG. 20

, in the case of the insertion member


52


being formed with grooves


44


, the blocking piece


53


can be pulled backwards from the access opening


1


once the unlocking piece


56


is inserted in position, thereby uncovering the access opening


1


, allowing the article


100


to be withdrawn from the casing A.
