Container
SUMMARY OF THE INVENTION 
     The present invention is directed to a novel collapsible container having side walls connected to a bottom wall. A top wall is integral with a first side wall by way of a fold line. The top wall has a first panel generally perpendicular to said first side wall and a second panel generally parallel to a second side wall which is opposite said first side wall. The second side wall is longer than the first side wall by a distance corresponding generally to the length of said second panel. At least one blocking ear is provided on a third side wall for holding the top wall panels in said disposition. 
     It is an object of the present invention to provide a novel multi-purpose collapsible container. 
     It is a further object of the present invention to provide a collapsible container which may be used for retrieving animal excrement. 
     It is another object of the present invention to provide a collapsible container which can be made from a single sheet of paperboard and which is easily erected by the user and having positive locking means for retaining the container in a closed disposition. 
     Other objects will appear hereinafter.

     Referring to the drawings in detail, wherein like numerals indicate like elements, there is shown in FIG. 1 a container in accordance with the present invention designated generally as 10. The container 10 has a plurality of interconnected side walls 12, 14, 16 and 18. Each side wall is connected to an adjacent side wall by a score line 17 so as to facilitate folding one side wall with respect to the next adjacent side wall. 
     The container 10 includes a bottom wall designated generally as 19 and which will be described in greater detail hereinafter. The container 10 also includes a top wall designated generally as 20. The top wall 20 is comprised of panels 22 and 24 interconnected by a score line or perforated line 28. Panel 22 is connected to the side wall 12 by a score line or perforation line 26. The side wall 16 is longer than the side wall 12 by a distance corresponding generally to the height of panel 22. See FIG. 2. 
     A slot 30 is provided at the intersection of side walls 14 and 16 at the upper end thereof. A slot 32 is provided at the intersection of side walls 16 and 18 at the upper end thereof. See FIG. 1. Panel 24 has tabs 34 and 36 on opposite ends thereof. When the container 10 is assembled, tab 34 will be disposed in slot 30 and tab 36 will be disposed in slot 32. 
     Side wall 14 is provided with an ear 38. Ear 38 is delineated by way of score line or perforation line 40 and is generally triangular in shape. Ear 38 has a tab 42 along one side edge thereof. 
     Side wall 18 has an ear 44 which is generally triangular in shape and delineated by way of fold line or perforation line 46. Ear 44 has a tab 48 along one side edge. 
     Panel 22 of the top wall 20 has a slot 50 along one side edge and a slot 52 along an opposite side edge. The slots 50, 52 are adjacent and extend from the line 28. See FIG. 2. Tab 48 is produced when slot 50 is cut. 
     If desired, the upper edge of side wall 16 may be provided with serrations 54. When the container 10 is used in connection with retrieval of animal excrement, it may be provided with an integral scoop 56. Scoop 56 is integral along one side edge with the side wall 12 and is delineated by the fold or perforation line 58. If desired, scoop 56 may be provided with a longitudinally extending score line 60 to facilitate bending the scoop 56. Scoop 56 is of a size generally corresponding to the size of side wall 12. 
     Referring to FIG. 2, there is illustrated a one piece blank in plan view and from which the container 10 is assembled. A tab 62 is provided integral with a side edge of side wall 14 and is delineated by way of the score line or perforation line 66. Adhesive 64 is provided on one surface of the tab 62. When assembling the container 10, the adhesive 64 on one face of the tab 62 will be bonded to an inner surface of side wall 12 along and adjacent to the line 58. 
     The bottom wall 19 of the container is comprised of four panels with each panel being integral with one of the side walls 12, 14, 16 and 18. Referring to the lower end of FIG. 2, a panel 68 is connected to the side wall 12 by a fold line or perforation line 70. Panel 68 has a tab 74, a locking portion 76, and an angled edge 77 extending from locking portion 76. Panel 68 has an angled edge 72. The angled edges 72, 77 are mutually perpendicular and are each at an angle of approximately 45° with respect to line 70. 
     A panel 78 is integral with the side wall 18 and is connected thereto by a fold line or perforation line 80. Panel 78 is generally a right triangle divided in half by way of a fold line or perforation line 82. Line 82 delineates one side edge of portion 84 having adhesive thereon. The adhesive on portion 84 is to be attached to the end of panel 68 remote from the angled edge 72. 
     The panel 86 is connected to side wall 16 by way of a fold line or perforation line 90. Panel 86 has a locking portion 88 and an angled edge 89 extending therefrom. Panel 86 has a portion 94 delineated along one side edge by the fold line or perforation line 92. Portion 94 has adhesive thereon and is adapted to overlie and join panel 86 to a panel 96. 
     A panel 96 is connected to side wall 14 by way of fold line or perforation line 98. Panel 96 is generally a right triangle and has a portion 102 delineated along one edge by way of the fold line or perforation line 100. Portions 94 and 102 are of the same size and are to be joined to one another. 
     When assembling the blank as shown in FIG. 2 into a collapsed container as shown in FIG. 6, the adhesive on tab 62 is joined to the inner surface of side wall 12, the adhesive on portion 84 is joined to the adjacent portion of panel 68, and the adhesive on portion 94 is joined to portion 102. In order to erect the collapsed container from the disposition shown in FIG. 6 to the disposition shown in FIG. 1, it is only necessary to apply inwardly directed pressure at points A and B. See FIG. 7. Continued application of such pressure causes edges 77 and 89 to slide along one another until the locking portions 77 and 88 interlock. 
     The container 10 is now in condition for filling. When the container 10 is used for retrieving animal excrement, the scoop 56 is torn off along line 58. The container is held in the disposition shown in FIG. 1. The serrations 54 act as a rake. The excrement is scooped into the container 10 and thereafter the scoop 56 is also introduced into the container 10. 
     To close the container 10, the top wall 20 is pressed inwardly until panel 22 is generally perpendicular to the side wall 12 and side wall 16. Panel 24 will overlie side wall 16. Tab 34 will enter slot 30 and tab 36 will enter slot 32. When the tabs 34, 36 bottom out in their respective slots, panel 22 will be perpendicular to the side walls 12 and 16. As a result of the tabs 34, 36 and their related slots, panel 22 of the top wall 20 cannot be pushed into the container beyond its position perpendicular to the side walls 12 and 16. 
     Thereafter, the ears 38 and 44 are bent inwardly as shown in FIG. 4. After tab 42 on ear 38 enters slot 50 and tab 48 on ear 44 enters slot 52, the container 10 is locked in a closed disposition whereby the top wall cannot accidentally pop open. Thereafter, the container 10 when used for retrieving animal excrement may be deposited in the nearest trash can. 
     The container of the present invention is characterized by the one piece construction which facilitates rapid manufacture at low cost and the easy to erect feature with respect to the bottom wall whereby no panels are required to be manipulated by the user. Further, there is a positive locking feature with respect to the top wall as described above and illustrated in the drawings. 
     The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention.
