The problem partly removed; is made more acute in many retail stores wherein floor FIG. 4 is a side and top perspective view of the box space is fairly well utilized so that it is difficult to install 20 mounted on a shelf; additional shelving or counter space. This lack of shelf FIG. 5 is a plan view to reduced scale of a one-piece or counter space makes it particularly difficult to have box blank that may be used in forming the box of FIGS. new and relatively untested articles prominently displayed. 14. The problems outlined above are solved and further The embodiment of the invention as illustrated in FIGS. advantages are obtained with the provision of the novel, 25 1 to 5 comprises a generally rectangular box 10, of rela inexpensive box construction of this invention which is also referred to herein as a shelf extender. In general, this box which is of paper or equivalent construction, is of tively light and ?exible paper material or the equivalent. The rectangular box 10 which for the present purpose is elongated and relatively shallow has a bottom 12, a front rectangular form and provided with a cover flap having 30 14, a back 16, opposed sides or ends 18, 18, rear side pressure sensitive features.

This arrangement of the ad 50 strip 36. The blank, as shown in FIG. 5, may be formed of any hesive strip does not interfere with the printed surface suitable sheet material such as cardboard, metal foil, containing advertising matter or instructions; also, the stiffened fabric, treated papers and the like. The pres pressure sensitive adhesive holds on to the box much bet sure sensitive ‘adhesive means 34 can be that of a tape ter by being applied to the inside of the flap since as is (as shown in FIG. 1) having pressure sensitive adhesive conventional with many paper boxes, the outside or ex posed surfaces thereof are coated to improve the appear ance of the box whereas the paper in the inner part of the box is uncoated and provides a better surface for the adhesive; still another integral panel on the cover ?ap 55 means on both sides and which has been secured to the panel 32 or the pressure sensitive adhesive can be ap plied directly to the panel 32. The masking strip 36 is preferably made somewhat longer than the pressure sensi tive adhesive means 34 so that a projecting end of the beyond the pressure sensitive adhesive carrying panel can 60 masking strip may be conveniently grasped for tearing give support to the back portion of the box both for pre the same away from the adhesive layer. The masking venting the box from tilting on counters whose thickness strip 36 may be made of holland cloth, glassine, parch is not equal to or greater than that of the back wall of the box and also to assist certain types of box construction in holding together. Additional objects of the invention are to provide a box of this kind with a readily detachable masking strip on the exposed pressure sensitive adhesive so that the ment paper and the like which will adhere to the adhesive 65 coating, but will readily peel therefrom. The shelf extender of this invention can be sturdily mounted and can easily support up to about 5.5 pounds of articles when the box is one such as described in FIGS. 1-5 wherein the box has internal dimensions of 10 inches box may be conveniently handled as an article of man between the sides (width); 4 inches between the front and ufacture which can act as an extender of the shelf space 70 without interfering with the articles displayed on the shelf to which it is attached nor obstructing the view of articles back (length) and wherein the front is 1.5 inches high and the back is about 2.75 inches high. In a box of aomgoaa.v those dimensions the adhesive containing panel is about 1.75 inches long and about 9.75 inches wide with a sub stantial area of the inside surface of the panel 32 covered with the pressure sensitive adhesive means 34. It is pref erable that the paper be about 0.03 of an inch in thickness when it possesses the above mentioned dimensions. Of course, the shelf extender can be larger or smaller in its various dimensions from those speci?cally mentioned 4 cover ?ap panel 52 is equal to the length of the adhesive carrying cover ?ap panel 32. The masking strip 36 is then removed from the pressure sensitive adhesive means 34 and the shelf extender box 10 is ready for attachment to the shelf 8. The attachment to the shelf is preferably accomplished by ?rst lining up in adjacent relationship the top of the marginal cover ?ap panel 26 with the top of the shelf 8, as in FIG. 4 and then bending outwardly and downwardly the panels 32 and 52, after the masking herein. The fact that the pressure sensitive ‘adhesive is on the inside of the cover ?ap permits greater weights to 10 strip 36 has been removed, and subsequently applying be supported by the box than if the pressure sensitive ad pressure with the hand to the ?rst cover ?ap panel 52 to attach the box as‘shown in FIG. 4. What is claimed is: hesive were on the outside of the cover flap. The pres sure sensitive adhesive means can be operable over a wide temperature range such as down to freezing and up to about 150° F. Other blanks than that which is shown in FIG. 5 can also be used in this invention provided that they employ a cover ?ap‘ such as that shown by nu meral 24.
