For the purpose of illustration and not for the purpose of limiting the scope of the disclosure, the following detailed description describes beverage containers (e.g., glass beverage bottles) as disposed within the carton embodiments. In this specification, the terms “lower,” “bottom,” “upper” and “top” indicate orientations determined in relation to fully erected and upright cartons.
The carton blank 3 has a longitudinal axis L1 and a lateral axis L2. In the illustrated embodiment, the blank 3 comprises a top panel 10 foldably connected to a first side panel 20 at a first lateral fold line 21. A bottom panel 30 is foldably connected to the first side panel 20 at a second lateral fold line 31. A second side panel 40 is foldably connected to the bottom panel 30 at a third lateral fold line 41. In the illustrated embodiment, the blank 3 includes an attachment flap 50 foldably connected to the top panel 10 at a fourth lateral fold line 52. Any of the top and bottom panels 10, 30 and the first and second side panels 20, 40 can be otherwise shaped, arranged, configured, or omitted, without departing from the disclosure. For example, the blank 3 can alternatively include two top panels cooperating to form a top of the carton 5 or two bottom panels cooperating to form a bottom of the carton. Additionally, the attachment flap 50 could be foldably connected to the second side panel 40 in an alternative embodiment.
The top panel 10 is foldably connected to a first top end flap 12 and a second top end flap 14. The first side panel 20 is foldably connected to a first side end flap 22 and a second side end flap 24. The bottom panel 30 is foldably connected to a first bottom end flap 32 and a second bottom end flap 34. The second side panel 40 is foldably connected to a first side end flap 42 and a second side end flap 44. When the carton 5 is erected, the top and bottom end flaps 12 and 32 and side end flaps 22 and 42 close the first end 51 (
In one embodiment, the top and bottom end flaps 12 and 32 and side end flaps 22 and 42 extend along a first marginal area of the blank 3, and are foldably connected at a first longitudinal fold line 62 that extends along the length of the blank. In the illustrated embodiment, the top and bottom end flaps 14 and 34 and side end flaps 24 and 44 extend along a second marginal area of the blank 3, and are foldably connected at a second longitudinal fold line 64 that also extends along the length of the blank. The longitudinal fold lines 62, 64 may be, for example, substantially straight, or offset at one or more locations to account for blank thickness or for other factors.
In one embodiment, the side end flaps 22, 24 each include a compression tab 25, 26 respectively foldably connected thereto at a lateral fold line 27, 28 respectively. In the illustrated embodiment, the compression tabs 25, 26 are at least partially defined by oblique cut lines 29, 36 extending from fold lines 27, 28 to a respective top edge of the side end flaps 22, 24. Similarly, side end flaps 42, 44 each include compression tabs 43, 45 foldably connected thereto at lateral fold lines 47, 46 respectively, and being at least partially defined by oblique cut lines 49, 48, in a respective side end flap 42, 44, respectively, extending therefrom. Alternatively, the oblique cut lines 29, 36, 48, 49 could be otherwise shaped, arranged, and/or configured. Also, the oblique cut lines 29, 36, 48, 49 could be tear lines or other lines of weakening without departing from this disclosure.
According to the illustrated embodiment, the dispenser 7 comprises a dispenser pattern 54 including a dispenser panel 55 and a tear line 56 in at least the top panel 10. The dispenser panel 55 is separable from the top panel along the tear line 56 to form a dispenser opening (not shown) to provide access to the containers C within the carton. The tear line 56 forms first and second portions 58, 59 and an access panel 57 located at approximately the center of the top panel 10. The access panel 57 is removable to create an access opening capable of receiving a hand, fingers, or other apparatus to provide access to the dispenser portions 58, 59.
As shown in
In the illustrated embodiment, the insert blank 203 includes a first side flap 237 foldably connected to the central panel 206 at a lateral fold line 239 and a second side flap 241 foldably connected to the central panel 206 at a lateral fold line 243. In one embodiment, the second side flap 241 comprises a first portion 245 that is foldably connected to the central panel 206 at the fold line 243, a second portion 247 foldably connected to the first portion 245 at a lateral fold line 249. Each of the first portion 245 and second portion 247, are each independently positionable at respective fold lines 243, 249.
As shown in
As shown in
In accordance with the exemplary embodiment, the carton blank 3 with insert blank 203 can be further erected into the carton 5 by folding along fold lines 21, 31, 41, and 52 and adhering the attachment flap 50 to the second side panel 40 to form an open-ended sleeve 300 (
As shown in
In the illustrated embodiment, as the reinforcing end flap 212 and the top end flap 12 are downwardly folded, the shoulder 305 contacts the exterior surfaces of the compression tabs 25, 43 to fold the compression tabs along the respective fold lines 27, 47 into the interior space 301 (
As shown in
In one embodiment, the inwardly folded compression tabs 25, 43, 26, 45 can engage an underside of a rim or cap CP of the containers C adjacent the respective ends 51, 53 to further help secure the containers from movement. Additionally, the engagement of the compression tabs 25, 43, 26, 45 against the caps CP can help restrain the side end flaps 22, 42, 24, 44 when the end flaps are selectively glued together when closing the ends 51, 53 of the carton 5. When closing the first end 51, for example, portions of the top end flap 12 can be glued to portions of the side end flaps 22, 42. As the top end flap 12 is pressed against the side end flaps 22, 42 during gluing, the compression tabs 25, 43 can push against the caps CP of the containers C adjacent the end 51 to support the side end flaps 22, 42. Accordingly, the compression tabs 25, 43 allow the compression of glue between the top end flap 12 against the side end flaps 22, 42 by providing a firm base against which the top end flap can be pressed to sufficiently squeeze the glue between the top end flap and the side end flaps. Similarly, the tabs 26, 45 can help support the side end flaps 24, 44 during the compression of glue between the top end flap 14 and side end flaps 24, 44 at the second end 53 of the carton 5.
The handle 11 can be used to grasp the carton 5 by pressing against the elongate handle flap 131 to provide a handle opening in the closed first end 51 of the carton 5. Similarly, the handle 111 can be used to grasp the carton 5 at the closed second end 53. As shown in
The dispenser 7 can be opened by separating the dispenser panel 55 from the top panel 10 to access to the containers C in the carton. The dispenser panel 55 can be adhered to the dispenser panel 250 of the insert blank 203 so that the dispenser panels 55, 250 are upwardly folded together to create a dispenser opening for accessing the containers C. The dispenser panels 55, 250 could be otherwise shaped, arranged, configured, and/or activated, without departing from the disclosure.
As shown in
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.
