The present disclosure generally relates to a carton for containing and dispensing contents, such a carton that may have a reclosable fitment, and a reclosable fitment for a carton.
One aspect of this disclosure is the provision of a carton for containing and dispensing contents, and a fitment may optionally be mounted to an outer chamfered corner of the carton for being opened and closed to respectively provide and restrict access to the contents of the carton. The fitment may be molded of polymer material.
In one aspect of this disclosure, the carton comprises a plurality of panels respectively foldably connected to one another, and the plurality of panels extends around an interior of the carton. The plurality of panels may include opposite first and second major side panels, opposite first and second minor side panels that are each smaller than the first and second major side panels, a bottom panel at least partially closing a bottom end of the carton, a top panel at least partially closing a top end of the carton, and an oblique panel at least partially defining the chamfered corner of the carton. The oblique panel may extend between the first and second major side panels, the oblique panel may extend between the top panel and the first minor side panel, and the oblique panel may extend obliquely relative to each of the first and second major side panels, the first and second minor side panels, and the top and bottom panels. A dispenser (e.g., a hole) may be defined in the chamfered corner (e.g., in the oblique panel), for use in dispensing contents from the interior of the carton. When the carton is in combination with the fitment, the fitment may be mounted to the chamfered corner of the carton so that the fitment is for use in dispensing contents from the interior of the carton by way of the dispenser.
The carton may be erected from a blank in which a respective one of the minor panels has first and second edges that are opposite from one another, and third and fourth edges that are opposite from one another, wherein the third and fourth edges extend crosswise to the first and second edges. The oblique panel of the carton may be referred as a dispenser panel in the blank, and the dispenser panel is connected to the third edge of the respective minor panel by a fold line. The first and second major panels are respectively foldably connected to the first and second edges of the respective minor panel. Each of the first and second major side panels comprises an oblique edge, wherein the oblique edges extend outwardly from proximate respective ends of the fold line, and the oblique edges extending divergently with respect to one another in an outward direction away from the fold line. The dispenser panel is positioned between the oblique edges.
The carton may be partially erected from the blank, so that the opposite first and second major side panels are substantially parallel to one another and respectively extend from opposite edges of the minor side panels. The dispenser panel may be folded inwardly relative to the respective minor side panel, toward the oblique edges of the major side panels, so that the dispenser panel extends obliquely and at least partially defines the chamfered corner of the carton. As examples, the dispenser panel may be attached to outer surfaces of the major side panels by way of mounting flaps or mounting pleats foldably connected to the opposite edges of the dispenser panel, or in any other suitable manner.
According to one aspect of this disclosure, a base of the fitment may comprise a plurality of walls defining a rearwardly open receptacle for receiving the chamfered corner of the carton. The plurality of walls may extend around a passageway, and the passageway may extend through the base from the receptacle to a front opening of the passageway. A lid for opening and closing the front opening to the passageway may be removably connected to the base by a connector, such as a flexible hinge.
The fitment may be mounted to the chamfered corner of the carton, such as by causing relative movement between the carton and the fitment so that the chamfered corner is received in the rearward receptacle of the fitment. The fitment may optionally include one or more inwardly protruding mounting members that may engage in one or more holes and/or behind one or more edges of the carton. More specifically, the mounting member(s) may engage behind one or more panels (e.g., the mounting flaps or mounting pleats) of the carton for restricting the fitment from being pulled off of the chamfered corner of the carton.
The foregoing presents a simplified summary of some aspects of this disclosure in order to provide a basic understanding. The foregoing summary is not extensive and is not intended to identify key or critical elements of the invention or to delineate the scope of the invention. The purpose of the foregoing summary is to present some concepts of this disclosure in a simplified form as a prelude to the more detailed description that is presented later. For example, other aspects will become apparent from the following.
Having described some aspects of this disclosure in general terms, reference will now be made to the accompanying drawings, which illustrate exemplary embodiments of this disclosure, are not necessarily drawn to scale and may be schematic, and wherein:
Referring now in greater detail to the drawings, in which like numerals may refer to like parts throughout the several views, exemplary embodiments are described in the following.
The blank 3 has a longitudinal axis L1 and a lateral axis L2. The blank 3 has a first major side panel 10 foldably connected to a first minor side panel 30 at a first lateral fold line 11, a second major side panel 50 foldably connected to the first minor side panel 30 at a second lateral fold line 31, and a second minor side panel 70 foldably connected to the second major side panel 50 at a third lateral fold line 51. An attachment flap 90 is foldably connected to the second minor side panel 70 at a fourth lateral fold line 91, although the attachment flap may be foldably attached to the first major side panel 10, or at any other suitable location.
The first major side panel 10 is foldably connected to a top flap 16 and a bottom flap 18. The first minor side panel 30 is foldably connected to a mount assembly 300 and a bottom flap 38. The second major side panel 50 is foldably connected to a top flap 56 and a bottom flap 58. The second minor side panel 70 is foldably connected to a top flap 76 and a bottom flap 78. The top flaps 16, 56, 76 extend along a first or top marginal area of the blank 3. Top flap 16 is foldably connected to first major side panel 10 at a first longitudinally extending fold line 14. The mount assembly 300 is foldably connected to first minor side panel 30 at a second longitudinally extending fold line 33a. Top flap 56 is foldably connected to second major side panel 50, and top end flap 76 is foldably connected to second minor side panel 70, at a third longitudinally extending fold line 54. The bottom flaps 18, 38, 58, 78 extend along a second or bottom marginal area of the blank 3, and may be foldably connected along a fourth longitudinally extending fold line 64.
The first, second, third and fourth longitudinal fold lines 14, 33a, 54, 64 may be, for example, generally straight lines of disruption. Alternatively, the fold lines 14, 33a, 54, 64 may be offset at one or more locations to account for, for example, blank thickness or other factors. When the carton 5 (
The first major side panel 10 has an oblique edge 93 and the second major side panel 50 has an oblique edge 95. The oblique edge 93 extends between the fold lines 14, 33a. The oblique edge 95 extends between the fold lines 33a, 54. The upper regions of the oblique edges 93, 95 are immediately adjacent wide holes through the blank 3, whereas the lower regions of the oblique edges 93, 95 are merely separated from the mount assembly 300 by respective slits or other suitable cuts.
As will be discussed in greater detail below, when the blank 3 is erected into the carton 5 (
Referring to
In accordance with the first embodiment, when the liner 97 is included, it may be laminated or otherwise attached to the mount assembly 300, such as by way of adhesive material that is in close proximity to, and circumscribes, the dispenser opening 83, so that the dispenser opening 83 is fully closed by the liner 97. As will be discussed in greater detail below, after the carton 5 (
Optionally, the liner 97 and/or blank 3 includes feature(s) that seek to aid in the manual opening of the dispenser opening 83. For example, the liner 97 may include a line of weakening 89 (e.g., tear line) that is proximate to and shaped substantially similarly to the periphery of the dispenser opening 83. The line of weakening 89 may be in the form of kiss cut(s) and/or a series of perforations (e.g., micro-perforations) that typically do not extend through the entire thickness of the liner 97, so that the line of weakening does not (e.g., substantially does not) define open passageways that extend through the entire thickness of the liner 97. Accordingly and in accordance with the first embodiment, prior to tearing along the line of weakening 89, the line of weakening 89 does not (substantially does not) degrade the barrier function provided by the liner 97. The line of weakening 89 may be formed by laser scoring, die cutting, heat stamping, or any other suitable method.
In accordance with the first embodiment, in addition to the dispenser opening 83 being closed by the predetermined portion of the liner 97 that extends across the dispenser opening 83, at least some of the portion of the liner 97 that that extends across the dispenser opening 83 may optionally have a reinforcement 68 mounted thereto. For example, the reinforcement 68 may be a portion of the blank 3 that is not removed from the dispenser opening 83 when the dispenser opening is formed. More specifically and in accordance with the first embodiment, the reinforcement 68 is a central portion of the dispenser panel 36. In this regard, the reinforcement 68 may be connected to and/or separated from a remaining portion of the dispenser panel 36 by a disruption, or more particularly a line of disruption 69, such as a tear line and/or a slit. As shown in
In
As mentioned previously, the liner 97 may be omitted. As another alternative, only a portion of the liner 97 may be included, such as that portion that is mounted to and associated with the mount assembly 300, and that portion of the liner may be referred to as a patch. Those of ordinary skill in the art will understand that it is well known to mount a liner and/or patch to a carton blank. Accordingly, the liner 97 may be constructed of any suitable material, and may be mounted to the blank 3 in any suitable manner. For example, the liner 97 or patch may be mounted to the blank 3 through the use of a “window machine” (e.g., a machine for mounting patches, windows (e.g., clear polymer films), or the like, to carton blanks). This mounting may be carried out through laminating, the use of adhesive material and/or in any other suitable manner.
When the liner 97 is included, the fixed connections (e.g., adhesive material) between the blank 3 and the liner 97 are typically arranged in a manner that allows the blank 3 to be erected into the carton 5 (
One example of a method of forming the carton 5 (
The top of the carton 5 may be closed by inwardly folding the top flap 76, and then inwardly folding the top flaps 16, 56, so that these top flaps at least partially overlap one another. Adhesive material, or any other suitable fastening mechanism, may be applied to secure the top flaps 16, 56, 76 in their closed configuration. As at least partially shown in
The mount assembly 300 is erected to close a front portion 108 of the top of the carton 5. The mount assembly 300 is folded inwardly about fold line 33a so that the dispenser panel 36 abuts each of the oblique edges 93, 95 of the first and second major side panels 10, 50, and the front edges of the top flaps 16, 56 (e.g., the front edge of the top end panel of the carton 5). In this configuration, the dispenser panel 36 extends obliquely (e.g., the dispenser panel is an oblique panel) and the dispenser panel at least partially defines the chamfered corner of the carton 5. The dispenser panel 36 is typically connected to one or more of the major side panels 10, 50 and the top end panel of the carton 5 to retain the dispenser panel in its oblique configuration. More specifically, the mount assembly 300 is further erected by folding the mounting flaps 81, 85, 88 inwardly relative to the dispenser panel 36. As partially shown in
At this point in the assembly process, both the lower end of the carton 5 and the lower end of the bag formed from the liner 97 are open. Product(s) such as food products (not shown) or any other suitable contents may be placed into the bag formed from the liner 97 by way of its open end. Then, the open end of the bag formed from the liner 97 may be sealed closed, such as by forming a pinch seal, fin seal, foldover seal and/or any other suitable seal in that end of the bag. The seals by which the liner 97 is formed into the bag/closed bag may be formed in any suitable manner. For example, the seals may be formed through the use of adhesive material (e.g., glue and/or a hot melt or sonically activatable adhesive material).
The bottom of the carton 5 can be closed by folding the bottom flaps 38, 78 inwardly, followed by folding the bottom flaps 18, 58 inwardly, so that the bottom flaps at least partially overlap one another. Adhesive material, or any other suitable fastening mechanism, may be applied to secure the bottom flaps 18, 38, 58, 78 in their closed configuration. One or more of the inwardly folded bottom flaps 18, 38, 58, 78 may be characterized as forming a bottom panel or bottom end panel of the carton 5, and the bottom end panel of the carton may be constructed in any suitable manner. The bottom end panel closes the bottom end of the carton 5, or more generally the bottom end panel at least partially closes the bottom end of the carton. That is, even if the bottom end panel does not fully close the bottom end of the carton 5, the liner 97, when present, may fully enclose the contents of the carton. Alternatively, the bottom end of the liner 97 and carton 5 may be closed first, following by filling the bag formed from the liner at its open upper end, and then closing the upper end of the bag and the carton.
The base 202 of the fitment 200 may optionally include side flanges 223, 227 extending upwardly from oblique edges of the side walls 203, 205, respectively. The hinge 208 is flexible for allowing the lid 210 to be moved relative to the opening 213 between an open configuration, which is shown in
The fitment 200 typically includes a releasable locking mechanism for releasably securing the lid 210 in the closed configuration. In accordance with the first embodiment, the locking mechanism defines a releasable interference fit/press fit/friction fit, or the like, between the base 202 and the lid 210. For example and as best understood with reference to
The plurality of walls 203, 204, 205, 206 of the base 202 define a rearwardly open mounting receptacle of the fitment 200, and the rearwardly open mounting receptacle is for receiving the chamfered corner of the carton 5. The walls 203, 204, 205, 206 extend around a passageway that extends through the base 202, and the passageway extends from the mounting receptacle to the front opening 213 of the passageway.
Referring also to
The fitment 200 may be mounted to the chamfered corner of the carton 5 by way of relative movement between the carton and the fitment, such that the chamfered corner is received in the rearward mounting receptacle of the fitment. For example, when the rearward mounting receptacle of the base 202 of the fitment 200 is pushed onto the erected mount assembly 300/obliquely configured, front, upper, chamfered corner of the carton 5, the base continues to slide farther onto the chamfered corner defined by the mount assembly until the inner surfaces of both the lower and upper walls 204, 206 of the base 202 fully and snuggly abut the respective portions of the carton 5 in a manner that arrests the relative movement between the carton and the base of the fitment. At substantially the same time as the arresting, the ends of the mounting protrusions 209 that are closest to the opening 213 respectively move past and engage the edges of the mounting flaps 81, 88 that are farthest from the dispenser panel 36. The respective engagement between these ends of the mounting protrusions 209 and these edges of the mounting flaps 81, 88 restricts, or at least inhibits, the base 202 of the fitment 200 from being moved relative to (e.g., being pulled off of) the chamfered corner of the carton 5 such that the base of the fitment is substantially fixedly mounted onto the chamfered corner. For each pair of mounting protrusions 209 shown in
Alternatively or in addition, adhesive material may be positioned between the base 202 of the fitment 200 and the chamfered corner of the carton 5 for holding them together, and/or any other suitable fastening mechanisms may be used between the base and the chamfered corner of the carton 5. For example and in accordance with the first embodiment, adhesive material in combination with the interaction between the ends of the mounting protrusions 209 and the edges of the mounting flaps 81, 88 fixedly connects the base 202 of the fitment 200 to the chamfered corner of the carton 5. Alternatively, there may be any other suitable connection(s) between the base 202 of the fitment 200 and the chamfered corner of the carton 5, and these connection(s) may be releasable, such as if it is desired to reuse the fitment 200 or separate it from the carton for recycling purposes, or the like.
One example of a method of using carton 5 (
When the user desires to access contents within the bag, which is formed by the liner 97 within the carton 5, the lid 210 of the fitment 200 may be manually opened relative to the base 202 of the fitment (e.g., see
Then, the portion of the liner 89 that obstructs the dispenser opening 83 may be removed from dispenser opening 83. More specifically and in accordance with the first embodiment, the user may open the dispenser opening 83 by inserting a finger through the portion of the liner 97 that extends across the dispenser opening 83 and is adjacent to the reinforcement 68, to initiate tearing along the line of weakening 89. Then, the user may arrange the inserted finger behind the reinforcement 68, and pull outwardly to complete the tearing along the line of weakening 89 to remove the reinforcement and the portion of the liner bound by the line of weakening from the dispenser opening 83.
With the fitment's opening 83 and the dispenser opening 213 both opened, contents of the bag within the carton 5 may be poured from the bag/carton 5 by way of the openings 83, 213. After some of the contents have been poured from the carton 5, the lid 210 of the fitment 200 can be returned to its closed configuration (
The fitment 200 may be reopened and closed numerous times, for accessing the remainder of the contents of the carton 5. The reclosable fitment 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 fitment described herein can be modified, changed, and/or omitted without departing from the disclosure.
In accordance with the third embodiment, the blank 403 and carton 405 and/or fitment 200, 202′ may include additional and/or different mounting features that seek to aid in the mounting of the fitment to the erected mount assembly 407/chamfered corner of the carton 405. For example and in accordance with the third embodiment, the first minor side panel 30 includes a mounting feature that may be in the form of a disruption, such as a mounting hole or slot 32, or other cut out or the like, for receiving a corresponding mounting feature (e.g., mounting protrusion) that may be formed integrally with and protrude inwardly from the inner surface of the lower front wall 204, 204′ of the fitment 200, 200′. That is, a mounting protrusion that is shaped like and is smaller than the mounting slot 32 may protrude inwardly from the inner surface of the lower front wall 204, 204′ of the fitment 200, 200′ for being received in the mounting slot, so that the mounting protrusion is engaged to an edge of the slot for restricting the fitment 200, 202′ from being pulled off of the chamfered corner of the carton 5. Alternatively or in addition, the first and second embodiments may include the mounting features of the third embodiment, and vice versa, and a variety of other mounting features are also within the scope of this disclosure.
In accordance with the fourth embodiment, the mount assembly 507 has four web or pleat panels 508, 509, 510, 511. The pleat panel 508 is partially defined by the lateral fold line 31 and oblique fold line 517. The pleat panel 509 is partially defined by lateral fold line 11 and oblique fold line 519. The pleat panel 510 is partially defined by the oblique fold line 517 and an oblique fold line 521. The pleat panel 511 is partially defined by the oblique fold line 519 and an oblique fold line 523. The pleat panel 508 is foldably connected to the dispenser panel 36 by lateral fold line 31, and to pleat panel 510 by oblique fold line 517. The pleat panel 509 is foldably connected to the dispenser panel 36 by lateral fold line 11, and to pleat panel 511 by oblique fold line 519. The pleat panel 510 is foldably connected to the second major side panel 50 by oblique fold line 521 and to pleat panel 508 by oblique fold line 517. The pleat panel 511 is foldably connected to the first major side panel 10 by oblique fold line 523, and to pleat panel 509 by oblique fold line 519.
The mount assembly 507 of the fourth embodiment may be erected as discussed above for the mount assembly 300 of the first embodiment, except that as the dispenser panel 36 of the fourth embodiment is folded inwardly about the fold line 33a, the pleat panels 508, 509, 510, 511 are folded outwardly and rearwardly, and the inwardly oriented faces of the pleat panels 510, 511 are respectively attached to (e.g., glued to or otherwise adhesively attached to, or attached in any other suitable manner) to the outwardly oriented faces of the side panels 50, 10, so that the pleat panels 508, 510 are in opposing face-to-face contact with one another, and the pleat panels 509, 511 are in opposing face-to-face contact with one another. Optionally, there may be adhesive material at these face-to-face contacts between the pleat panels, or the like. The combination of the foldably connected/rearward edges of the pleat panels 508, 510 and the combination of the foldably connected/rearward edges of the pleat panels 509, 511 are typically for engaging the respective ends of the mounting protrusions 209 (
The pleat panels 508, 510 may together be referred to as a pleat. Similarly, the pleat panels 509, 511 may together be referred to as a pleat. Differently configured pleats and pleat panels 508, 509, 510, 511 may be used. Alternatively, the first through third embodiments may include the pleat panels 508, 509, 510, 511/mount assembly 507 of the fourth embodiment, and vice versa, and a variety of other pleat panels/mounting flaps/mount assemblies are also within the scope of this disclosure.
In accordance with one aspect of this disclosure, the dispenser panel 36 comprises opposite edges, and there are one or more panels (e.g., the side mounting flaps 81, 88 of
In accordance with the fifth embodiment, the mount assembly 607 has side mounting flaps 608, 610 and a top mounting flap 609 that are respectively foldably connected to the dispenser panel 36 at fold lines 33b, 33c, 87. The side and top mounting flaps 608, 610, 609 may be characterized as being wings, or wing-like flaps. The side mounting flaps 608, 610 are respectively separated from the side panels 10, 50 by cuts that are more specifically in the form of oblique slits 611, 613. Alternatively, the first through fourth embodiments may include side and top mounting flaps 608, 610, 609/the mount assembly 607 of the fifth embodiment, and vice versa, and a variety of other mounting flaps/mount assemblies are also within the scope of this disclosure.
In accordance with the sixth embodiment, a liner 797 may be mounted to the blank 703 as shown in
In accordance with the seventh embodiment, the dispenser opening 883 is substantially in the shape of a pentagon, although the dispenser opening may define a variety of different shapes. Also in accordance with the seventh embodiment, the side mounting flaps 881, 888 are respectively foldably connected to oblique edges of the side panels 10, 50 by oblique fold lines 833, 834; and separated from the dispenser panel 836 by cuts or slits 836, 838, respectively.
Alternatively, the fitments 200, 200′ may be omitted or replaced with any other suitable type of fitments or pour spouts, such as reclosable fitments and reclosable pour spouts, that may be mounted to the chamfered corner/mount assembly 300, 407, 507, 607 at any suitable time, such as before and/or after the respective blank is erected. For example, the entire disclosure of each of the following documents is incorporated herein by reference: U.S. Pat. Nos. 6,152,360; 5,429,297; 5,102,485 and 4,846,915; and U.S. Patent Application Publication No. 2006/0255109. Also for example, suitable polymeric reclosable fitments and/or polymeric reclosable pour spouts may be available from Roberts PolyPro, Inc. of Charlotte, N.C. 28273
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, 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 a line 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 of 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.
