Definitions
- the invention is a continuation-in-part of our patent application Ser. No. 710,302 filed Mar. 4, 1968 now abandoned, and relates to a regular slotted shippingcarton provided with end-loading and top-opening features.
- the outer free edges of the front top wall panels of the carton abut and are connected by the manufacturers joint.
- the novel end closure includes top wall flaps free of connection with other closure flaps but maintained in place by contact with the inner surface of the front and rear wall flaps which are adhesively connected to the bottom wall flaps.
- top wall closure flaps are not adhesively connected to the adjacent closure flaps, the top wall panel and the top wall closure flaps may be removed by breaking the manufacturers seal and pivoting the top wall panel about its hinged connection with the rear wall panel. Ready access to the goods packaged in the carton is had through openings provided between the front and rear wall closure flaps.
- One embodiment of this invention provides such manufacturers with an end-loading, top-opening shipping carton which will dispense with the necessity and inclination of grocery clerks to use knives for opening the carton and another embodiment provides protection for the goods as a glue panel is severed in order to gain entry to the carton thus providing both manufacturers and the store owners with the attendant savings.
- the instant invention relates only to a shipping carton made from a regular slotted carton blank.
- the manner in which the end closure is effected provides a new and unusual result in that a regular slotted carton may be quickly and easily opened without fear of cutting the product packages.
- this invention involves a regular slotted carton blank, it may be handled by any conventional case loading and sealing equipment adapted for regular slotted cartons.
- FIG. 1 is a plan view of the outside face of a foldable blank from which the embodiment of the carton of FIGS. 1-6 is formed.
- FIG. 2 is a fragmentary perspective view of the blank of FIG. 1 erected to a tubular configuration and ready to be loaded.
- FIG. 3 is a fragmentary perspective view depicting the first step of closing the embodiment of FIGS. 1-6.
- FIG. 4 is a fragmentary perspective view of the carton of FIG. 3 in a sealed condition and the initial opening step of breaking the tear-strip seal.
- FIG. 5 is a fragmentary perspective view of the carton with the tear-strip seal completely broken and the top wall panel being pivoted about its rear edge during the opening process.
- FIG. 7 is a fragmentary plan view of a foldable blank from which the alternate embodiment of FIGS. 7-11 is formed.
- FIG. 8 is a fragmentary perspective view of the blank of FIG. 7 erected to a tubular configuration and ready to be loaded.
- FIG. 9 is a fragmentary perspective view of the carton of FIGS. 7-11 after the manufacturers seal has been broken and the top panel partially lifted.
- FIG. 10 is a fragmentary end elevation view of the carton in the area of the manufacturers seal.
- FIG. 11 is a fragmentary end elevation view similar to FIG. 10 after the manufacturers seal has been severed and the top wall panel partially lifted.
- the carton blank generally designated by reference numeral 20 as shown in FIG. 1 includes top wall panel 21, rear wall panel 22, bottom wall panel 23 and front wall panel 24 foldably connected in series relation by lines of scoring 26-28 inclusive.
- Top wall closure fiaps 41 and 42 are provided with cutouts 35 also for a reason to be hereinafter explained.
- FIGS. 2-5 depict the carton in progressive stages of erection, closing and opening. Since the invention relates to a carton having identical closures at each end which are easily closed and opened, the description shall follow the chronological stages of closing and opening one end only.
- Tear-strip tape 50 comprises adhesive backing 51 and a heavy tear string 52. Tear-strip tape of this type is generally known and is preferred, however, it is conceived other easyopening seals may be substituted therefore.
- glue areas 33 and 34 extend over approximately the lower 50% of the front and rear wall closure flaps 43 and 47.
- the end closure of the embodiment of FIGS. 3-5 is affected by first folding the top and bottom wall closure flaps 41 and 45 to a closed position as shown in FIG. 3.
- glue is applied to glue areas 34 and 33 on front and rear wall closure flaps 47 and 43 respectively.
- flaps 47 and 43 it may be applied to bottom wall flap 45 with similar results.
- Front and rear wall closure flaps 47 and 43 are then infolded to the position shown in FIG. 4, and pressure is applied to affect a firm adhesive connection between bottom wall flap 45 and the front and rear wall flaps. It will be noted that the top wall flap 41 is free of any adhesive connection with the adjacent front and rear wall closure flaps.
- the container With the container in the loaded and sealed position as shown in FIG. 4, the container is ready to be shipped or stored.
- the carton has all the attributes of a regular slotted carton, the front and rear wall closure flaps provide a vertical column for stacking strength as does the vertically aligned top and bottom wall closure flaps.
- top wall flap 41 is not connected to either of the adjacent closure flaps, the top wall panel 21 may be readily removed by lifting its outer free edge 31 (see FIG. thus pivoting top wall panel 21 about perforated score connection 26.
- Cut-out 35 has been provided in the front edge of the top wall closure flaps to prevent the flaps from binding against the front wall panel as the top wall panel is pivoted about hinged connection 26. Cut-out 35 may be of any configuration, for example the angular configuration of FIGS. 7-11, as long as enough material is removed from the front edge of the flaps to prevent binding. The cut-out must not, however, extend beyond the 4 outer free edge 64 (FIG. 5) of flap 47 as the product packages would be exposed.
- top wall panel may be completely removed from the carton by tearing along perforated score connection 26. This is however, unnecessary to the price marking and removal of the product packages from the carton and therefore optional.
- the product packages 66 are exposed and readily available when the top wall panel is removed. This enables the manufacturer to place his product packages in the shipping carton such that the tops of the packages are exposed and thus, may be easily price marked by a grocery clerk before the product packages are removed from the shipping carton.
- FIG. 6 depicts a modificaion of the embodiment of FIGS. 1-5 in a view similar to that of FIG. 4.
- This modification comprises an end closure whereby bottom wall flap 45 is adhered to the outer surface of front and rear wall closure flaps 47 and 43 instead of the inner surface as in the carton shown in FIG. 4.
- top wall flap 41 is adjacent the inner face of the front and rear wall closure flaps 47 and 43.
- glue may be applied to either the bottom wall flap or the front and rear wall flaps to effect the adhesive seal.
- FIGS. 7-11 depict an alternative embodiment of the invention whereby the tear-strip tape seal of the embodiment of FIGS. l6 has been replaced by a glue flap hingedly connected to the outer free edge of the top wall panel.
- the glue flap is adhesively connected along a substantial portion of its inner surface to the adjacent front wall panel, however, there is a glue-free area immediately above the adhesive connection such that the glue flap may be severed thus providing entry to the carton.
- the adjacent front wall panel protects the packaged goods from the severing instrument as the glue flap is being severed.
- FIG. 7 a portion of the blank of the alternative embodiment is shown and it includes top wall panel 121, top wall flaps 141 and 142.
- Glue flap 171 is hingedly connected to front wall panel 121 by line of scoring 131.
- the inner surface of glue flap 171 includes glue area 173 and glue-free area 174 between the glue area and the hinge connection 131.
- FIG. 8 shows the blank of FIG. 7 in a tubular configuration with glue flap 171 adhesively connected to the front wall panel thus providing the manufacturers seal for the container.
- FIG. 10 further illustrates the manufacturers seal with glue flap 171 adhesively connected to the front wall panel in area of adhesive connection 173 and the glue-free area 174.
- FIG. 9 depicts the closure flap pattern of this embodiment which is identical to that of FIG. 6, explained above. Further, FIG. 9 shows how the top panel may be removed in a manner similar to that of FIG. once the glue flap 171 has been severed adjacent glue-free area 174. FIG. 11 further illustrates this feature showing glue flap 171 severed above the area of adhesive connection 173 which remains intact as the top panel is removed.
