fig1 shows a rectangular blank 10 of stiff paper or cardboard of a kind well - known for use in conventional glue traps . the blank is divided into two halves by a central perforated fold line 12 . on one surface ( the inner surface ) of each half of the blank there is a rectangular layer of very sticky glue , defined by lines 14 . glues suitable for use in traps of this nature are well - known the art and the selection of a particular glue is not a part of the instant invention and need not be described herein in detail . the glue layers are covered by a common sheet of release paper indicated by line 16 . surrounding the central area of the blank , which includes the glue layers and release paper , is a tear - away border portion , shown shaded , which is defined by perforated lines 18 , 20 and 22 . the inner surface of the blank is provided with adhesive , of any suitable kind known in the art , along the shaded border portion , so that when the blank is folded along line 12 &# 39 ;, the two halves of the blank will be permanently adhered together over the entire shaded area . in the non - shaded areas of the border portion of the blank there are formed suspension apertures 24 , 26 of unequal size for suspending the completed package from a display hook or the like and glue dots 25 for holding the non - shaded areas together . generally , the display printing will be placed on the side of the package having the small - size suspension aperture 24 , so that if there is any misalignment of the apertures , this will not be evident to a consumer viewing the display side of the package . the blank is folded along line 12 to form the package 10 &# 39 ; shown in fig2 and the shaded border areas become permanently adhered together while the non - shaded areas are adhered together by the glue dots . it is understood that the outer surface of the blank and package will be provided with printed matter ( not shown ) such as instructions for use , trade names , advertising and the like . to form the package 10 &# 39 ; into a glue trap , the permanently adhered border region of the package 10 &# 39 ; is torn away along lines 18 , 20 and the package is then unfolded , breaking apart the glue dots 25 , to expose the release paper - covered glue areas . if desired , the trap can be divided into two glue boards by tearing along line 12 . the blank 30 shown in fig3 is of similar materials to blank 10 and is designed to form two separate tent - like glue traps 31 as shown in fig5 . again , the blank is divided into two halves by a perforated fold and tear line 32 . each half of the blank again has a rectangular glue layer on its inner surface , indicated in each case by a dotted line 34 . the glue layers are covered by a common sheet of release paper indicated by line 36 . in this embodiment , the blank also has transverse fold lines 38 , 40 dividing each half of the blank into three foldable panels . again , a border area of the blank , shown shaded , and defined by tear - away perforation lines 46 - 58 is provided with adhesive on the inner surface of the blank . die - cut tabs 42 are formed between lines 48 , 50 and 52 , 50 and complimentary interfitting tabs 44 are formed at the opposite end of the blank . suspension apertures 60 , 62 of unequal size are again provided , in this case in the tear - away portion of the border region . blank 30 is folded along line 32 to form a glue trap package 30 &# 39 ; as shown in fig4 with opposite portions of the blank forming the shaded border area being permanently adhered together . again , the outer surface of the blank may be printed with suitable display material . to form the package into two traps 31 , the glued border region is torn away along lines 46 - 58 and the package is unfolded and separated along line 32 after removal of the release paper covering the glue areas . each half of the remaining blank will have a shape as shown in fig3 with the shaded areas removed , and each half of the blank can then be formed into a trap 31 ( fig5 ) by folding along lines 38 , 40 and by inter - engaging the tabs 42 , 44 . while only preferred embodiments of the invention have been described herein in detail , the invention is not limited thereby and modifications can be made within the scope of the attached claims .
disposable glue traps for catching rodents such as rats or mice are formed by sheets of folded paper or cardboard each provided with a glue layer . each folded sheet has a self - adherent tear - away border so that a trap forms its own packaging , thereby dispensing with the need for separate outer packaging materials .
