Description

ni ed Patent PAN CARTON" RussellJaHennessey and kobertvMafDunning, St. Paul, Mimn, assignors to Waldorf Paper Ptroducts Company, a corporation of Minnesota Application June 22, 1955, Serial.No.'517,177
2 Claims. (Cl. 206-46) This invention relates to an improvement in pan carton and deals particularly with a sleeve for containing a pan of merchandise.
In recent years considerable merchandise has been sold in pan-shaped containers made either of metal foil or of somewhat more rigid material. For example, chicken pies in a frozen state have been packaged and sold in pan-type foil packages. Other such pies which need not be kept under refrigeration are sold in pantype receptacles having hermetically sealed covers. It is with this type of receptacle that the present invention is particularly useful.
An object of the present invention lies in the provision of a sleeve for containing a pan-shaped object having a recessed upper end or top closure. The sleeve includes a pair of opposed flaps which are bent out of the plane of the sleeve top and into the recessed end to hold the receptacle from sliding from either end of the sleeve.
A further feature of the present invention resides in the provision of a sleeve which fits tightly about the pan. The receptacles are usually tapered in form, the bottom of the receptacle being of substantially shorter radius than the receptacle top. When a pan of this type is closed within a rectangular sleeve, the top and bottom walls tend to bow upwardly and downwardly, respectively, due to the fact that the lower portion of the receptacle does not extend the full width of the sleeve. In the present arrangement the sleeve is constructed to taper inwardly at the bottom so as to more nearly fit the contour of the receptacle and therefore to fit more properly about the receptacle.
These and other objects and novel features of our invention will be more clearly and fully set forth in the following specification and claims.
In the drawings forming a part of the specification:
Figure l is a perspective view of the sleeve with the receptacle in place therein.
Figure 2 is a sectional view through the sleeve and receptacle showing the manner in which the flaps hold the receptacle in the sleeve.
Figure 3 is a sectional view through the sleeve showing the manner in which the sleeve tends to follow the contour of the receptacle.
Figure 4 is a diagrammatic view of the blank from which the sleeve is formed.
With reference to Figure 4 of the drawing the sleeve is shown as including a side wall panel having connected thereto along a fold line 11 a glue flap 12. A second side wall portion 13 is foldably connected to the side wall panel 10 by a fold line 14. A fold line 15 connects the side wall portion 13 with a bottom panel 16. The bottom panel 16 is foldably connected along a fold line 17 to a side wall portion 19. This side wall portion 19 is foldably connected along a fold line 20 to a second side wall portion 21. This second side wall portion 21 is foldably connected along a fold line 22 to the top panel 23.
When the carton is formed, the sleeve is folded along 2,904,170. Patentedasept. 1 5, 1959 the fold line 1 4 so that the side wall portion 10- and the glue flap 12overlie the. side wall portion 1 3 and the bottom panel- 16. The sleeve is also folded along.
fold lines 14 and 22' while. the. various. panels are folded:
flat upon. one another.
The: top panel 23-includes.apairvof spaced flaps 242 and? 2.5. I Theflap 24-is defined by any arcuate out line. 26,-, short parallel side cuts 27 and 29, and a fold line 30 which is parallel to a side edge of the sleeve. The flap 25 is similarly formed with an inner arcuate cut line 31 connecting parallel short cut lines 32 and 33, the ends of which are joined by a fold line 34.
The fold lines 30 and 34 are parallel and the cut lines 26 and 31 are approximately of equal radius to the inner surface of the recessed top of the receptacle 35 which is enclosed within the sleeve. Usually these arcuate cut lines defining the ends of the flaps 24 and 25 are located at short distances inwardly from the opposite edges 36 and 37 of the sleeve blank.
The receptacle 35 is a pan-shaped structure having a bottom panel 39 and a tapered peripheral wall 40 extend ing upwardly and outwardly therefrom. A cover 41 comprises a disc-shape body having a chime or a groove 42 about its periphery which encloses the upper edge of the side wall 40' in the customary manner. The top 41 is therefore recessed and the bead or chime 42 extends upwardly about the periphery of the cover to form a cylindrical shoulder against which the arcuate ends of the flaps 24 and 25 may engage, as is indicated in Figure 2 of the drawings.
The bottom panel 16 of the sleeve is of approximately the width of the diameter of the bottom 39 of the receptacle. The top panel 23 is approximately equal to the outer diameter of the top of the receptacle. Therefore, as the receptacle is inserted into the sleeve, the connected side wall panels 10, 13 and 19', 21 tend to straighten out toward a common plane. In view of the fact that there is a tendency for the carton stock to remain flat, this action exerts somewhat of a tension upon the top and bottom panels tending to hold them parallel. Furthermore, the connected panels forming each side wall can fold nearer to a common plane to compensate for slight variations in the depths of the receptacle. This structure tends to hold the top and bottom panels parallel and from bowing away from the container. When the same receptacle is placed in a rectangular sleeve, the bottom panel tends to bow downwardly as there is nothing to hold this bottom panel to its full width. This action tends to make the cover panel somewhat loose and permits it to bow upwardly. This bowing is to a large extent eliminated by the particular package arrangement illustrated.
In accordance with the patent statutes, we have described the principles of construction and operation of our pan carton, and while we have endeavored to set forth the best embodiment thereof, we desire to have it understood that changes may be made within the scope of the following claims without departing from the spirit of our invention.
We claim:
1. A can sleeve in combination with a receptacle having top of one diameter, a bottom of smaller diameter, and tapered side walls, the sleeve including a top panel overlying the receptacle top and of substantially equal width thereto, parallel side wall panels hingedly connected to opposite edges of said top panel, the top of said receptacle engaging said side walls and tending to hold them parallel, a bottom panel of a width substantially equal to the diameter of said receptacle bottom, and downwardly' and inwardly extending connecting panels connec i g the lower. edges of said sidewalls to opposite edges of said bottom panel, the combined height of said side wall panels and connecting panels being substantially greater, thanthe length of the tapered side walls of'said.
receptacle, whereby folding said connected side wall panels and connecting panels into common planes will increasethe distance between said top and bottom panels to simplify insertion and removal of said receptacles.
2. The structure of claim 1 and in which said receptacle top is recessed, and including tab means cut from the body of said top panel and folded thereto along parallel fold lines parallel to' the sleeve ends, said tabs being folded to underlie portions of said top panel and to extend outwardly from the fold lines toward the nearest sleeve end, the ends of said tabs engaging in the recessed top of the receptacle.
