In one embodiment, the blank 3 includes the upper patch or upper liner 130a that is adhesively attached to the blank by upper glue lines 140 or other adhesive (FIG. 1). The upper liner 130a substantially covers the dispensing features of the blank 3 including the openings 112a, 114a, dispenser panels 202, 204, 206, 208, 210, at least portions of the dispenser tabs 80, 82, and at least a portion of the second end top flap 52. As shown in FIG. 1, the window portions 112b, 114b of the upper liner 130a overlap the respective openings 112a, 114a in the second end panel 50 and the side panels 30, 70 to form the window features 16, 17. The upper glue lines 140 at least partially seal off the area around the window portions 112b, 114b of the upper liner 130a to help prevent any product in the carton 5 from exiting the carton through the window features 16, 17. In one embodiment, the upper liner 130a is a patch of color accented PVDC material, which can be viewed at the window features 16, 17 to help indicate that the carton 5 includes the upper liner 130a for helping to reduce sifting and clumping of the product when dispensing through the dispenser 200. Alternatively, the liner could comprise other suitable materials. Further, the upper liner 130a could be transparent or translucent without departing from the disclosure. Also, the upper liner 130a, could be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
In the embodiment of FIG. 1, the lower patch or lower liner 130b is adhesively attached to the blank 3 by lower glue lines 160 or other suitable adhesive. The indicator portion 116b of the lower liner 130b covers the opening 116a in the end panel 50 to form the indicator window feature 18. The glue lines 160 can at least partially form a seal around the indicator portion 116b of the lower liner 130b to help prevent any product in the carton 5 from exiting the carton through the indicator window feature 18. In one embodiment, the end panel 50 includes a protrusion 210 that extends into the opening 116a. The blank 3 can include indicia (not shown) that is adjacent the protrusion 210 for warning a user that the carton 5 is nearly empty when the product level is at or below the protrusion 210, for example. In one embodiment, the lower liner 130b is a clear polymeric material such as cellophane or other suitable material so that the level of product in the carton 5 can be viewed through the indicator window feature 18. The opening 116a, the indicator portion 116b of the lower liner 130b, the protrusion 210, and the optional indicia are features of the blank 3 that at least partially form an indicator 220 of the carton 5. The liner 130b could be partially transparent, translucent, or non-transparent without departing from the disclosure. Also, the lower liner 130b, could be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
According to one exemplary method of construction, the carton 5 may be erected by folding the blank 3 about the lateral fold lines 31, 51, 71, 91 so that the attachment flap 90 is adhesively secured to or otherwise attached to the first side panel 10, and the blank 3 is formed into a generally open-ended sleeve with an interior 150 (FIG. 2A). Prior to forming the open-ended sleeve, the upper liner 130a and lower liner 130b have been attached to the blank 3 by respective glue lines or patterns 140, 160. In one embodiment the bottom of the partially erected carton 5 can be closed by folding the bottom flaps 14, 34, 54, 74 inwardly, to at least partially overlap the bottom end flaps and close the bottom end 92 of the carton 5.
A product such as a flowable material (e.g., cereal, rice, oatmeal, detergent, soap, etc.) may be placed in the interior space of the partially formed carton 5. The product can be placed in a bag or directly in the partially formed container without departing from the disclosure.
After filling the carton 5 with a product, the top 88 of the carton 5 is closed by folding and at least partially overlapping the top flaps 12, 32, 52, 72. As shown in FIG. 2B, the first side top flap 32 overlaps the second side top flap 72 with the second portion 81 of the end flap 32 being in face-to-face contact the second portion 85 of the second side top flap 72. The overlapped second portions 81, 85 of the side top flaps 32, 72 close a rear portion 89 of the top 88 of the carton (FIGS. 2B and 3). The dispenser tabs 80, 82 can be sized such that the edge margins of the dispenser taps partially overlap. Next, the second end top flap 52 is downwardly folded to fully close the top 88 of the carton 5. The erected carton 5 is shown in FIG. 3. As the side top flaps 32, 72 are folded over the top end 88, the portions of the upper liner 130a that overlap the dispenser tabs 80, 82 are also downwardly folded. Accordingly, the portions of the upper liner 130a that overlap the reclosable lid portion 57 of the second end top flap 52 are folded into a triangular shape (FIG. 2B). The configuration of the dispenser tabs 80, 82 and the reclosable lid portion 57 helps to form a gusset 132 of overlapped portions of the upper liner 130a, which can help to reduce leaking of the product through the dispenser 200, for example. The reclosable lid portion 57 of the second end top flap 52 overlaps the dispenser tabs 80, 82, and the distal portion 59 of the second end top flap 52 can be adhesively attached to or otherwise secured to the second portion 81 of the first side top flap 32. The second end top flap 52 and the dispenser tabs 80, 82 of the dispenser 200 are configured to close a front portion 87 of the top of the carton 5 (FIG. 3).
The dispenser 200 is positionable between an initially closed position (FIG. 3) and an open or dispensing position (FIG. 4) that provides access to the products held in the carton 5. Additionally, the dispenser 200 includes features that allow the dispenser to be closed (e.g., reclosed) after access to the products is no longer needed (FIG. 5). FIG. 3 illustrates the erected carton 5 with the dispenser 200 in the initially closed position, and FIG. 4 illustrates the carton 5 with the dispenser 200 being activated and opened. To activate the dispenser 200, the tear strip 100 is first torn and removed so that the reclosable lid portion 57 of the second end top flap 52 is free from attachment to the distal portion 59 of the second end top flap 52, wherein the distal portion 59 is adhesively attached to the first side top flap 32. After removing the tear strip 100, the reclosable lid portion 57 can be pivoted upward about fold line 62 allowing access to the dispenser tabs 80, 82. The dispenser tabs 80, 82 can be separated from the respective second portions 81, 85 of the respective side top flaps 32, 72 by tearing at the respective tear lines 84, 86. After separating the dispenser tabs 80, 82 from the respective second portions 81, 85 of the respective side top flaps 32, 72, the dispenser tabs 80, 82 can be upwardly folded so that the dispenser 200 is in the open or dispensing position of the carton 5 (FIG. 4). The product held in the interior 150 of the carton 5 can be poured or removed from the carton in the open or dispensing position of the dispenser 200.
As shown in FIG. 4, when the dispenser 200 is opened, the dispenser panels 202, 204, 206, 208, 210 can be flexed to position the dispenser in a position that facilitates removal of product from the carton 5. For example, the dispenser pattern can be flexed and/or squeezed to form a spout, or to otherwise help direct the product through the dispenser 200 when pouring. The dispenser panels 202, 204, 208, 210 can fold with respect to one another and with respect to the side panels 30, 70 and the end panel 50. Additionally, the reclosable lid portion 57 of the second end top flap 52 can fold along the lateral dispenser fold line 53 so that the reclosable lid portion 57 has a generally V-shaped cross-section. The upper liner 130a extends from the interior 150 of the carton 5 through the dispenser 200, overlapping the portions of the side panels 30, 70 adjacent the dispenser 200, the upper portion of the second end panel 50, and at least a portion of each of the reclosable lid portion 57 and the dispenser tabs 80, 82. Accordingly, the upper liner 130a can help guide the product from the interior 150 through the dispenser 200 as it is poured from the carton, and the upper liner can help to improve sift resistance and reduce clumping and bridging of the product in the dispenser 200.
As shown in FIG. 5, after removal of the product, the dispenser 200 can be closed by first downwardly folding the dispenser tabs 80, 82 and then downwardly folding the reclosable lid portion 57. The protrusion 55 on the reclosable lid portion 57 is sized and positioned to engage and/or interlock with the protrusion 98 of the second portion 81 of the first side top flap 32. The reclosable lid portion 57 can be retained in the reclosed position of the dispenser 200 by pressing down on the protrusion 55 such that the protrusion is forced past the protrusion 98. The protrusion 98 then overlaps and engages the protrusion 55 and helps to prevent the lid portion from being upwardly folded. Similarly to when the top end 88 is initially closed, the closing the dispenser 200 can reform the gusset 132 in the upper liner 130a. For example, as the dispenser tabs 80, 82 are folded downwardly the portions of the upper liner 130a that overlap the dispenser tabs 80, 82 are also folded downwardly, and the portions of the upper liner 130a are overlapped in a triangle shape overlapping the reclosable lid portion 57 (similar to FIG. 2B). Accordingly, the gusset 132 can help to reduce leaking of the product through the reclosed dispenser 200.
The dispenser 200 can be reopened by pushing down on the protrusion 98 to release the protrusion 55 and the reclosable lid portion 57 so that the reclosable lid portion can be upwardly folded. The dispenser tabs 80, 82 can be upwardly folded so that the dispenser 200 is configured in the dispensing position of FIG. 4.
The dispenser 200 can be opened, reclosed, and reopened by various other steps or methods other than those described herein. Further, the steps of opening, reclosing, and reopening the dispenser described herein can be modified, changed, and/or omitted without departing from the disclosure.
The level of product in the carton 5 can be monitored by viewing the indicator 220 of the carton. As product is used, the level of material will be indicated through the indicator window feature 18 in the end panel 50. The protrusion 210 can help to indicate to a user that the carton 5 is nearly empty when the material level is at or below the protrusion 210, and that more product should be purchased.

As shown in FIG. 10, the lateral fold line 658 is connected to the oblique fold lines 614, 616 at respective curved fold lines 619, 621, which can be free from connection to the lateral fold lines 51, 71. Alternatively, the fold lines 619, 621 could be otherwise positioned. The dispenser 607 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
The blanks according to the present disclosure can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blanks can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blanks may then be coated with a varnish to protect any information printed on the blank. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. In accordance with the above-described embodiments, the blanks may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blanks can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton to function at least generally as described herein. The blanks can also be laminated or coated with one or more sheet-like materials at selected panels or panel sections.
In accordance with the above-described embodiments of the present disclosure, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present disclosure, fold lines include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed portion in the material along the desired line of weakness; a cut that extends partially into a 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; and various combinations of these features.
As an example, a tear line can include: a slit that extends partially into the material along the desired line of weakness, and/or a series of spaced apart slits that extend partially into and/or completely through the material along the desired line of weakness, or various combinations of these features. As a more specific example, one type tear line is in the form of a series of spaced apart slits that extend completely through the material, with adjacent slits being spaced apart slightly so that a nick (e.g., a small somewhat bridging-like piece of the material) is defined between the adjacent slits for typically temporarily connecting the material across the tear line. The nicks are broken during tearing along the tear line. The nicks typically are a relatively small percentage of the tear line, and alternatively the nicks can be omitted from or torn in a tear line such that the tear line is a continuous cut line. That is, it is within the scope of the present disclosure for each of the tear lines to be replaced with a continuous slit, or the like. For example, a cut line can be a continuous slit or could be wider than a slit without departing from the present disclosure.
The above embodiments may be described as having one or more panels adhered together by glue during erection of the carton embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place.
The foregoing description of the disclosure illustrates and describes various embodiments. As various changes could be made in the above construction without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Furthermore, the scope of the present disclosure covers various modifications, combinations, alterations, etc., of the above-described embodiments that are within the scope of the claims. Additionally, the disclosure shows and describes only selected embodiments of the disclosure, but the disclosure is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments of the disclosure.
