Description:
SUMMARY AND BACKGROUND OF INVENTION
This invention relates to an improvement in blanks for folding cartons. One aspect of the invention relates to improvements in folding cartons made from such blanks.
It is well known to provide certain types of containers with drawers or trays. The simple match box for wooden matches is an example, where a tray is slidably mounted inside a sleeve.
The present invention provides a one piece carton made from a single blank having a container portion and a drawer portion all formed from the single blank. The present invention also provides tamper proof construction or tamper detection means because the integrity of a seal has to be broken in order to gain access to the contents of the carton.
Preferred material for the present invention is paper or paperboard, preferably that having good folding qualities, and may be either coated or uncoated.
An object of the present invention is to provide a one piece folding carton having a container and a drawer portion. Another object of the invention is to provide a blank suitable for such a container.
Other objects, advantages and features will become apparent from the following specification and claims when read in conjunction with the drawings wherein:
FIG. 1 is a top view of a blank from which the present folding carton is to be made with glue patterns and embossing as seen from the inside of the blank or carton;
FIG. 2 is a side cross section of a fully erected carton showing the drawer partly extended or pulled out and as seen along section 2--2 of FIG. 4 were the carton fully assembled;
FIG. 3 is a schematic side view of the carton showing the manner in which certain panels are folded to provide the container and drawer;
FIG. 4 is a partly assembled and erected carton showing the panel folding sequence and other important particulars; and
FIG. 5 is an isometric view of the carton of FIG. 2 with the tab removed.
Referring first to FIG. 1, the blank 1 has a plurality of panels foldably connected to each other by score lines. The panels of the present blank comprise as seen from left to right in FIG. 1 an opening panel 2, front panel 3, top outside panel 4, back panel 5, bottom outside panel 7, drawer inside front panel 8, drawer top 9, and inside glue flap 10 respectively separated from and hingedly connected to each other by the parallel score lines (from left to right) 12, 14, 15, 16, 17, 18 and 19. Two longitudinal or side score lines 20, 21 extend lengthwise of the blank and separate the aforesaid panels 12 . . . 19 from a variety of side flaps and panels foldably connected thereto by one or another of the longitudinal score lines. Thus the two longitudinal scores respectively provide hinge connections on each side of the front panel 3 for outside flaps 22; on each side of the top outside panel 4 top glue flaps 23; on each side of the back panel 5 a glue flap 24; and on bottom or drawer panel 7 a drawer inner flap 25; on each side of the drawer inside front panel 8 a drawer outer front flap 26; and on each side of the drawer top 9 a drawer top side flap 27.
It should be apparent from FIG. 1 taken with the other drawings, the longitudinal or side score lines 20, 21 actually define the elements of sides of the carton.
The opening panel 2 is separated by a score line 33 preferably into two tabs, an outermost lifting tab 30 at the free edge and a glue tab 31 between the lifting tab and front panel. It is preferably removably connected between the front and bottom panels, thus the score line 12 is preferably a cut score or other type of weakness line so that the opening panel may be torn off for purposes described below.
The glue tab 31 is glued to the back of the bottom panel as viewed in FIG. 1, preferably using a plurality of spots of glue 32 each shown located within or registered with tearaway area 34 on panel 7, i.e., an area or areas surrounded by cutscores or perforation lines which will give way without severely damaging the appearance of the finished container when the opening panel is torn off.
Each of the top glue flaps 23 has an embossed area 35 as shown in FIG. 1. Assuming FIG. 1 is the inside of the carton blank, the embossed area is depressed as there viewed whereby the other side of the blank, which represents the outside of the carton, has the raised portion resulting from the embossment. The raised part 35 protrudes outwardly toward the viewer as seen in FIG. 4 enough to be in the same plane approximately as the outer surface of flaps 24 thus enhancing the adhesion to both of them of outside flaps 22.
The front edges 40 of the top glue flaps 23 are separated from the outside flaps 22 by a cutaway portion instead of merely a slit in order to provide the requisite mechanical clearance for the drawer to operate within the container portion as best seen in FIG. 2. Each back glue flap 24 has on the end adjacent the top panel 4 a cut out 41 for the embossment 35 (FIG. 4) to be received in upon erection.
The top panel has an operating or fingerhold 42 preferably a round hole cut in the middle thereof for purposes which will be described.
The drawer inner flaps 25 and drawer front flaps 26 are each cut away in the area that would be along their common score line. This also provides a desirable amount of mechanical clearance for ease of operating the drawer in and out of the container.
A dispensing window 43 is cut at least in one of the drawer front panel and bottom panel, but preferably is cut so as to straddle the score line 17 shared by the last two mentioned panels. In the illustrated embodiment, the dispensing window extends the full width of the front panel in order to facilitate removal of whatever the contents may be from the drawer.
The drawer top side flaps 27 are likewise cut away fore and aft as at 44 to provide mechanical clearance.
Referring first to FIG. 3, when the carton is erected glue 51 is first applied to the area 51 at the top end of the back panel and the glue flap is then adhered to said back panel. Glue can alternatively be applied to the surfaces and panels that are described as being glued to the panels above described as initially receiving the glue. Glue includes any suitable adhesive.
Note that the "wrap-around" arrangement of the panels provides a drawer movable in and out of the container but which is integral therewith by reason of certain panels being commonly shared, e.g. the back and bottom panels 5, 7. The drawer top 9 swings about the hinge at score 19 to permit and help to limit drawer motion.
Once the panels have been glued together as shown in FIG. 3 (at 51 and 32,34) the various flaps and side panels must then be folded in the sequence discernible from FIG. 4 where the top glue flaps 23, drawer inner flaps 25 and top side flaps 27 are first folded, then the back glue flaps 24 are folded, and finally the outside flaps 22 folded and glued.
The purpose of the embossed areas 35 is to provide a raised region so the glue patterns 53 on the outside flaps will more readily engage the outside flap with both the top glue flap (at the embossment) and with the back glue flap. Ideally the embossment raises the glue surface of the top glue flap by an amount equal to the thickness of the material.
In the normal industrial use of this invenion, all glue except that in areas 53 on the outside flaps 22 is applied at the factory and the blank is folded and glued in the fashion described above for FIG. 3 without any of the side flaps being glued. Later, at the customer's factory after goods have been placed inside the box, glue is applied to the outside flaps in the areas 53 and the requisite folding and sealing is then done as shown in FIG. 4 in order to make a complete package.
When first erected, e.g., as after FIG. 4 is completed, the drawer cannot be moved out of the carton. The structure is rigid because opening tab 2 is securely glued in place preventing drawer movement and thereby giving a tamper proof container.
In use, the opening tab 2 is removed by tearing it away along the line of weakness 12, which can involve pulling the lifting tab and thereby breaking the glue 32 in the tearaway areas 34. When that is done the drawer can be moved in and out of the container by inserting one's finger in the hole 42 and pushing back and forth or alternatively by grabbing hold of the dispensing window 43 as exposed by tearing away the opening flap and pulling the drawer out, or a combination of both opening means may be employed.
Observe that the side flaps 22 are so glued that the various drawer top, front and side flaps 24, 25, 26, 27 do not become secured to anything. Only the outside, top glue and back glue flaps 22, 23, 24 are glued to each other thus constituting what I prefer to call container sides assemblies. The drawer sides (flaps 24 . . . 27) underlap the side assemblies and are not adhered or secured to anything except by sole reason of the hinged connections along their score lines to their respective supporting panels at the drawer front top and bottom: these flaps must be free to enable the drawer to move in and out of the container.
