Abstract

A carton includes a spout dispenser formed in a top panel of the carton. The spout dispenser is formed from a spout section of a side top flap adhered to an end top flap. Pivoting the spout section away from the top panel causes part of the end top flap to be pulled through an aperture through which product can be dispensed.

Description

BACKGROUND

The present invention relates to a carton according to the preamble of claim 1. Moreover, it relates to a blank as defined in the preamble of claim 9 and to a method of dispensing product from carton.
Dispensing cartons are known. Such cartons typically have a top panel formed from flaps that are separable to open the top of the carton. The contents of the carton can then be dispensed from the open carton top. Such cartons, however, typically are not easily closed once opened, and may not provide for easy dispensing of the carton contents.
One solution to this problem is to include a pivotable dispenser that can be opened for dispensing the carton contents and then closed for storage. Conventional pivotable dispensers, however, may be difficult to open and/or to place in a dispensing configuration. Many conventional dispensers also require a metal or plastic insert spout piece to form the dispensing portion of the carton, which may increase costs and/or complexity of manufacture.
A carton of the generic type as defined in the preamble of claim 1, which carton has a pivotable dispenser, is known from US 4,168,003 A . This carton has a removable cover strip in the second side top flap. After removal of said cover strip the dispenser structure formed in the first end top flap is exposed for being opened through the aperture in the first side flap.
The present invention aims at improving the prior art carton in terms of handling and reliability of the dispensing structure.

SUMMARY

The object set out above is achieved by a carton as defined in claim 1, by a blank as defined in claim 9 and by a method as defined in claim 13, respectively.
According to a first aspect of the invention, a carton comprises particularly a first side panel, a first end panel, a second side panel, a second end panel, a bottom panel and a top panel. The top panel comprises a first end top flap, a first side top flap overlying the first end top flap and having an aperture formed therein, and a second side top flap overlying the first side top flap. The first end top flap is adhered to the underside of the second side top flap through the aperture in the first side top flap. A plurality of lines of disruption in the second side top flap define in part a pivotable dispenser in the top panel.
Thus, the pivotable dispenser may be placed in a dispensing configuration by breaching the plurality of lines of disruption in the second side top flap and pulling the dispenser open. An access flap can be defined in the dispenser to allow a user to insert a finger into the top panel and thereby access the dispenser. Accessing and opening the dispenser can be performed using a relatively simple motion.
According to a second aspect of the invention, the first end top flap can include a spout section having wing portions. The wing portions can engage inside edges of the aperture in the first side top flap to secure the dispenser in the dispensing configuration. Locking cuts may be formed in the top panel in which the wing portions can be removably engaged to further secure the dispenser in the dispensing configuration. The dispenser can be closed by pressing the dispenser back into the top panel.
According to a third aspect of the invention, the spout dispenser can be formed from the top flaps of the carton such that no additional inserts or pieces etc. are required.
Other aspects, features, and details of the present invention can be more completely understood by reference to the following detailed description, taken in conjunction with the drawings and from the appended claims.

DETAILED DESCRIPTION

The present invention generally relates to dispensing or pour features for cartons. The present invention can be used, for example, in cartons that contain articles or other products such as, for example, food and beverages. The articles can also include particulate products such as, for example, rice, beans, sugar, and other pourable dry products. In this specification, the relative terms "bottom," "side," "end," and "top" may indicate orientations determined in relation to fully erected and upright cartons.
FIG. 1 is a plan view of a blank 8 used to form a carton 190 having a pivotable spout dispenser 160 (illustrated in FIGS. 3A and 3B ) according to a first embodiment of the invention. The blank 8 comprises a first side panel 10, a first end panel 20 connected to the first side panel 10 at a first transverse fold line 21, a second side panel 30 foldably connected to the first end panel 20 at a second transverse fold line 31, and a second end panel 40 foldably connected to the second side panel 30 at a third transverse fold line 41. An adhesive panel 50 may be foldably connected to the first side panel 10 at a fourth transverse fold line 51.
The first side panel 10 is foldably connected to a first side top flap 12 and a first side bottom flap 14. The first end panel 20 is foldably connected to a first end top flap 22 and a first end bottom flap 24. The second side panel 30 is foldably connected to a second side top flap 32 and a second side bottom flap 34. The second end panel 40 is foldably connected to a second end top flap 42 and a second end bottom flap 44. The top flaps 12, 22, 32, 42 extend along a first or top marginal portion of the blank 8, and may be foldably connected along a first longitudinal fold line 62. The bottom flaps 14, 24, 34, 44 extend along a second or bottom marginal portion of the blank 8, and may be foldably connected along a second longitudinal fold line 64. The longitudinal fold lines 62, 64 may be straight fold lines, or may be offset at one or more locations to account for, for example, blank thickness. When the carton 190 is erected, the top flaps 12, 22, 32, 42 close a first or top opening of the carton 190, and the bottom flaps 14, 24, 34, 44 close a second or bottom opening of the carton 190.
A spout dispenser pattern 100 is formed in the blank 8. According to an aspect of the invention, the spout dispenser pattern 100 includes lines of disruption formed in the first side top flap 12, the first end top flap 22, and the second side top flap 32. The spout dispenser pattern 100 defines the pivotable spout dispenser 160 in the erected carton 190 ( FIGS. 3A and 3B ).
Referring to FIG. 1 , the spout dispenser pattern 100 includes an aperture 110 formed from a plurality of lines of disruption in the first side top flap 12. The aperture 110 is defined by spaced side cut lines 112, an end cut line 114, and an arcuate end cut line 116. The cut lines 112 define shoulders 118 on either side of the aperture 110. The cut lines 112, 114, 116 of the exemplary embodiment define the opening or aperture 110 in the first side top flap 12. Alternatively, the lines 112,114, 116 could be breachable lines of disruption (e.g. tear lines) in the flap 12 defining a knockout panel (not illustrated). The knockout panel could be removed during erection of the blank 8.
In the first top end flap 22, a pair of dogleg-shaped cut-crease lines 128 (e.g., fold lines) extend from a distal end of the flap 22 to the first longitudinal fold line 62. A longitudinally extending cut-crease fold line 130 extends through a medial portion of the first top end flap 22 and across the cut-crease lines 128. The lines 128, 130 define a central portion 120, first and second wing portions 122, and a base 124 in the first end top flap 22. The central portion 120 is foldably connected to the base 124 at the fold line 130. At the first end top flap 22, the longitudinal fold line 62 can include a cut-crease section 132.
In the second side top flap 32, a spout section 138 is defined by a plurality of lines of disruption. The spout section 138 includes a central spout portion 140 and first and second wing portions 142 defined by dogleg-shaped interior side cut-crease lines 148 (e.g., fold lines), spaced exterior side cut-space lines 149 (e.g., tear lines), and a laterally extending end fold line 152. An access flap 144 is defined by an arcuate cut-space line 145 (e.g., tear line) connecting the side cut-space lines 149 and a lateral fold line 150. Oblique locking cuts 154 extend outwardly from the exterior side cut-space lines 149.
The lines 128, 130, 148 may be formed from, for example, cut-crease lines having 100% cuts (i.e., cuts that extend through the entire blank) in FIG. 1 , or partial cuts may also be used. Cut-space lines, for example, may also be used to form the lines 128, 130, 148. The lines 145, 149 are breachable lines of disruption that may be, for example, cut-space lines having 100% cuts or partial cuts. Cut-crease lines, for example, may also be used to form the lines 145, 149.
An exemplary process of erecting the carton 190 will be discussed with reference to FIGS. 1 and 2 . Referring to FIG. 1 , adhesive may be applied to the exterior side of the adhesive panel 50 and/or to the interior side of the second end flap 40. The blank 8 is folded about the transverse fold lines 21 and 41 to bring the exterior side of the adhesive flap 50 into contact with the interior or underside of the second end panel 40. The panels 40, 50 are thereby adhered together. The resulting article is then "opened" to have a generally closed tubular structure.
In order to close the top of the carton, adhesive is applied to the exterior side of the first end top flap 22 between the dogleg shaped cut-crease lines 128 and/or to the interior or underside of the spout section 138 of the second side top flap 32, between the dogleg shaped interior side cut-crease lines 148. Adhesive may also be applied to the underside of part of or the entirety of the exterior side of the first side top flap 12 except in the area of the shoulders 118. Alternatively or in addition to adhesive applied to the first side top flap 12, adhesive may be applied to the entirety of or part of the underside of the second side top flap 32 outside of the area defined by the lines 145, 149, 152, and so that the shoulders 118 are not adhered to the second side top flap 32. Adhesive may be applied to the entirety of or part of the upper surface of the second end top flap 42.
The top flaps 12, 22, 32, 42 may be closed by folding the first and second end top flaps 22, 42 down as shown in FIG. 2 . The first side top flap 12 is then folded over onto the end top flaps 22, 42 so that the side flap 12 overlies the end flaps 22, 42. The first side top flap 12 may be adhered to the second end top flap 42 at any desired location or locations. The underside of the first side top flap 12 may be adhered to the upper side of the first end top flap 22 in the area of the base 124.
The second side top flap 32 is folded over the first side top flap 12 so that the flap 32 overlies the flap 12. The underside of the second side top flap 32 may be adhered to the exterior or upper side of the first side top flap 12 in areas outside of the spout section 138. The upper or exterior side of the central portion 120 may be adhered to the underside of the central spout portion 140 of the second side top flap 32 through the aperture 110.
The bottom flaps 14, 24, 34, 44 may then be folded and adhered together to close the bottom of the carton. The resultant carton 190 is illustrated in FIGS. 3A and 3B . Dispensable product may be loaded into the carton 190 before closing both ends of the carton. If the contents of the carton 190 are to be held within a bag or other vessel, the bag (not shown) may be inserted into the partially closed carton before closing both ends of the carton.
Referring to FIGS. 3A and 3B , the top flaps 12, 22, 32, 42 are adhered together to form a top panel 170, and the bottom flaps 14, 24, 34, 44 are adhered together to form a bottom panel 180. The dispenser pattern 100 (illustrated in FIG. 1 ) in the top flaps 12, 22, 32 defines a pivotably (e.g., hingedly or foldably) attached spout dispenser 160 in the top panel 170. FIG. 4 is a top plan view of a portion of the top panel 170 illustrating the pivotable dispenser 160 in detail. As shown in FIG. 4 , the dispenser 160 can be formed entirely from the top flaps 12, 22, 32 comprising the top panel 170.
Referring to FIGS. 1-4 , the shape of the central portion 120 in the first end top flap 22 generally corresponds to the shape of the central spout portion 140 of the spout section 138, and the upper surface of the central portion 120 is adhered to the underside of the central spout portion 140 through the aperture 110 in the first end top flap 12. The wings 122 of the first end top flap 22 may remain unadhered to any other part of the carton 190.
FIGS. 5-7 illustrate an exemplary process of opening of the dispenser 160. Referring to FIG. 5 , a user inserts a finger, tool or other object into the top panel 170 at the access flap 144. The top panel 170 tears along the arcuate breachable line 145 as the access flap 144 is pressed inwardly.
Referring to FIG. 6 , the top panel 170 is further torn along the breachable lines 149 as the central spout portion 140 and wing portions 142 in the second side top panel 32 are pivoted outwardly about the fold line 152. The central portion 120 in the first end top flap 22 is adhered to the central spout portion 140 and the portion of the first end top flap 22 beyond the fold line 130 also pivots outwardly. This movement pulls the central portion 120 of the first end top flap 22 through the aperture 110 in the first side top panel 12. At the same time, contact with the sides of the aperture 110 causes the wings 122 in the first end top flap 22 to be folded inwardly at the lines 128 with respect to the central portion 120.
FIG. 7 illustrates the pivotable spout dispenser 160 opened and in its dispensing configuration, thereby forming a dispenser opening 165. Friction between the wings 122 and the interior edges of the aperture 110 serves to maintain the dispenser 160 in its dispensing configuration. If desired, the spout dispenser 160 can be pivoted open further so that the wings 122 engage the locking cuts 154. The pivotable dispenser 160 can be reclosed by simply pushing the dispenser 160 back towards the top panel 170. The shoulders 118 at each side of the aperture 110 project inwardly to partially occlude the aperture 110, and abut the wing portions 142 to prevent the dispenser 160 from being pressed too far in through the aperture 110.
According to the above-described embodiments, cartons can be provided with dispensers that are simple in construction, and that are easily opened and reclosed. The carton provides a relatively simple, one-step action for opening and dispensing product from the carton. The spout dispenser is formed from the top flaps of the carton and no additional inserts or pieces are required.
In the exemplary embodiment discussed above, the blank is formed from clay coated newsprint (CCN). In general, the blank may be constructed of paperboard, having a thickness of 0.3556 mm (caliper of at least about 14), so that it is heavier and more rigid than ordinary paper. The blank, and thus the carton, can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton to function at least generally as described above.
The first and second sides of the blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images. The blank may then be coated with a varnish to protect any information printed on the blank. The blank may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. The blank can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
In accordance with the exemplary embodiments, a fold line can be any substantially linear, although not necessarily straight, form of weakening or disruption in a blank that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present invention, fold lines include: score lines, creases, cuts that extend partially into a material along a desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness, and various combinations of these features.
For purposes of the description presented herein, the term "line of disruption" can be used to generally refer to either a crease line, a tear line, or a fold line formed in the material (or a combination of at least one tear line, fold line, etc.). A breachable line of disruption is a line of disruption that is intended to be breached during ordinary use of the carton. An example of a breachable line of disruption is a tear line.
A tear line can be any form of weakening that facilitates tearing therealong. Specifically, but not for the purpose of narrowing the scope of the present invention, tear lines include: a cut that extends partially into the material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness, or various combinations of these features.
The term "line" as used herein includes not only straight lines, but also other types of lines such as curved, curvilinear or angularly displaced lines.
The above embodiments may be described as having one or more panels adhered together by glue. The term "glue" is intended to encompass all manner of adhesives commonly used to secure paperboard carton panels in place.
In the present specification, a "panel" or "flap" need not be flat or otherwise planar. A "panel" or "flap" can, for example, comprise a plurality of interconnected generally flat or planar sections.
It will be understood by those skilled in the art that while the present invention has been discussed above with reference to preferred embodiments, various additions, modifications, and variations can be made thereto without departing from scope of the present invention as set forth in the following claims.
