Even with windows, however, some packagesfdoV not permit a satisfactory view to f.t he. .n side ofthe package. For example, "bacon is commonly stacked in shingle form before. being wrapped and pack 2.121 n URE4 wherein the inspection aphas been removed to :expand thev windowl area an'd per'rnit bett'erfinsperction of thecontentsof the package; FIGURE'E isa perspective view ofa r modifiedv carton FIGURE 7 `i s a' perspective view of the cartonof FIG- URE 6jwhereinthe inspection'naps of the carton have been 'liftedt permit'bette'r inspection of'the contents of the packagei j FIGURE 8 is aplan view of another modified carton; '"'FIGURE'Q 'is a perspective view of the cartonl of FIG- URE 8 illustrating the inspection Vhap being lifted toper f nit better inspection of the contents of the package. Referringagain'to the drawings'andnore particularly to'FIGURE 1 lthefprefsent invention provdes'a blankfl of sheet material, preferably polyethylene coated paper board, which `is suitably cut and scoredto form, when folded, acarton'. f` The blank 1 illustrated in FIGURE 1 includes a top p anel or wall 2 connected to a bottom panel 3 by a side Wall 4 and scored lines 5 and 6. Another side wa1l7 -The present invention rr`elates`lto packagegand 'more and its associated glue vflap 8 provide for closing the walls of the carton together as best shown in FIGURES 2 and 3. Suitable panels 9-12 and dust flaps 13-16 provideend closures for the carton.
f The top pane1'2 of the carton has a central portion cut away to form a window opening 17. A window 18 aged. When seen through a package window,' a fu 1l view v of the bacon is.;b locked becausein shingle stakingthe bacon slices obscure each other and the top bacon slice occurs below the window level and is out of sight.
The present invention vprovides a carton especially constructed so that the contents Lo'fFthe 'package may be exposed to satisfactory viewing. With bacon, -for example, the present invention provides for I iftingthe 4portion of the carton bordering the window s tha t the top. bacbn slice can be observed. i
Accordingly, an object of the present 'invention is to M provide a carton having a structure to permit better viewing of the contents of the package. i
Another object of the present invention is to provide a carton having a window whe-rein the carton structure bordering the window can be lifted to permit a consumer to inspect the interior of the package.
Other and further objects will become apparent upon an understanding of the illustrative embodiments about to be described or `will be apparent to one skilled in the art on employment of the invention.
A preferred embodiment of the present invention has been chosen for purposes of illustrating the principles of the present invention and is set forth in the drawings wherein:
FIGURE 1 is a plan view of a blank of sheet material having a window area, which when erected, form a carton according to the present invention;
FIGURE 2 is a perspective view of a carton formed from the blank of FIGURE 1 and having an end closure in the open position =for receiving a product such as bacon;
FIGURE 3 is a section view taken along line 3 3 of FIGURE 2 illustrating in particular the position of the carton window with respect to the top and side walls of the carton;
FIGURE 4 is a perspective view of a carton corresponding to FIGURE 2 which has been filled and sealed to form a package;
FIGURE 5 is a perspective view of the carton o'f FIG- 'of suitable transparent material, like cellophane, isse- 'cured as by a suitable adhesive 19 to the top panel 2 and the side wall 4 over the window opening 17..
It will be observed that the window 18 is adhered to both the top panel 2 and the adjoining side wall 4. That is to say, adhesive bonds the window to a portion of the top panel bordering .the window opening 17 and to the lside wall 4. An inspection ,tlap 20 is connected. by a scored'linef21 to the top edge of the side wall 4 and I by` lines of weakness 22 to the top panel- 2.
FIGURE 2 illustrates the blank 1 afterit hasvbeen folded into the form of a carton. The glue ap 8 .has been adhered to the top panel 2 and one end closure 23 has been formed. The other end .closure 24 ofthe carton in FIGURE 2 is open to receive a Iproduct 25 such as bacon (FIGURE 4). FIGURES 2 and 3 illustrate the position of the windowv 18 and the adhesive areas 19 with respect to the top and side walls of the carton. As best shown in FIG- URE 3 there is no adhesive between the window 18 and the inspection flap 20. Therefore, the inspection ap 20 may be lifted away from the window 18 to permit inspection thereunder. As shown in FIGURE 5 the inspection flap 20 may `be torn along the lines of weak ness 22 to permit better viewing of the product 25 inside the package, particularly the area under the inspection flap 20.
A modified form of the invention is illustrated in FIG- URES 6 and 7. The carton 26 illustrated in FIGURE 6 may be made from a blank 1 identical to that shown in FIGURE 1 except for the arrangement of the inspection flaps 27 and 28. As shown in FIGURES 6 and 7, the window 18 is adhered by an adhesive 19 to the top panel 2 and side wall 4 of the carton 26. The window 18 is covered by an upper inspection flap 27 connected to the top panel 2 by a scored line 29 and by a line of weakness 30. The lower inspection ap 28 is connected to the upper edge of the side wall by a scored line 5 and to the top panel 2 by lines of weakness 22. If desired, a line of weakness 31 may interconnect the inspection aps 27 and 28. Neither the upper nor the lower inspection flaps are connected to the window. The inspection flaps may be lifted as in FIGURE 7 to expose the product 25 to inspection.
FIGURES 8 and 9 illustrate a further modification of thefpresent inventiomThe carton 32 in FIGURES 8 and 9 may be made from the blank 1 of FIGURE 1 and is characterized by a single inspection flap 33 which covers the entire window opening-17. As shown in FIGURE 10, theinspection flap'33 is hingedly connected by a scored line S to the top edge of the side wall 4 and is defined by lines of weakness34 and 35 to permit easy separation and lifting of the inspection flap 33. The window 18 is connected to the top panel 2 and side wall 4 of the modification of FIGURES 9 and 10 in the same manner as the window 18 is secured to the embodiments of FIGURES 1 through 5 and 6 and 7. The inspection ap 33 may be separated along the lines of weakness 34 and 35 and pivoted about the scored line 5to expose the contents of the package.
It will be apparent that applicant has provided a new and useful package having greater consumer appeal in that it permits inspection of the contents of a package and which has special utility in packaging bacon.
