Description

Carton package for liquid consumable products and carton blank for carton package

Technical Field

The present invention relates to a carton package for a liquid consumable and a blank for a carton package.

Background

A wide variety of carton packages for liquid consumable products are currently used to accommodate a variety of different products and needs. The configuration and shape of the carton package has an impact in several aspects, such as ease of use, both in terms of handling of the package itself and the nature of the package and the degree to which the type of opening mechanism is coordinated with the characteristics of the different filled products. For example, highly viscous filled products may be more difficult to remove from the package, and often require more manipulation of the package to remove the final residue therefrom. A larger opening may facilitate such removal, but at the same time may reduce the degree of control in pouring the contents from the opening. The latter may be particularly disadvantageous in the case of the same packaging container being used for less viscous products, for example for cost-saving reasons. This can also be particularly troublesome for people with impaired motor skills or other disabilities that make it difficult to effectively remove the product. Thus, a trade-off is often required to find a compromise between easy handling of the package and its mechanical properties, resulting in overall performance of certain product categories being sub-optimal.

Disclosure of Invention

It is an object of the present invention to at least partially overcome one or more limitations of the prior art. In particular, it is an object of the present invention to provide a carton package and an associated blank for a carton package which allow easy removal of the filled product during use.

In a first aspect of the invention, this is achieved by a carton package for a liquid consumable comprising a top panel, a bottom panel, a body extending between the top panel and the bottom panel. The main body includes a front panel, a rear panel, a left panel, and a right panel, each of the front, rear, left, and right panels extending from the bottom panel to the top panel, the front panel connected to the top panel along a front top edge, the left panel connected to the top panel along a left top edge. The front top edge extends between the left and right panels and has a center point. The left top edge extends between the front panel and the rear panel and has a center point. The carton package includes an opening device disposed on the top panel, the opening device having a center point with an offset distance from a first line perpendicular to the front top edge and extending through its center point. The area of the top panel is greater than the area of the bottom panel.

In a second aspect of the invention, this is achieved by a carton blank for a carton package comprising a first longitudinal crease line defining a left front edge and a left top edge of the carton package, a second longitudinal crease line defining a front right edge and a right top edge of the carton package, a front panel portion, a rear panel portion, a left panel portion and a right panel portion. The carton blank includes a first transverse crease line including a first portion defining a front top edge, and a second portion at an opposite end of the first portion defining upper oblique side portions of the left and right panel portions of the carton package. The second portion of the first transverse crease line is angled relative to its first portion. The front panel portion is connected to the top panel portion along the front top edge. The front top edge extends between the first longitudinal crease line and the second longitudinal crease line and has a central point. The carton blank includes a removable opening portion disposed on the top panel portion, the removable opening portion having a center point with an offset distance from a first line perpendicular to the front top edge and extending through its center point.

Having an opening means with an off-centre position on the top panel whilst having the top panel with a larger area than the bottom panel facilitates removal of the filled product as a larger opening can be accommodated on the top panel whilst the offset position of the opening means improves the degree of control when pouring out the filled product.

Further examples of the invention are defined in the dependent claims, wherein features of the first aspect may be used to implement the second aspect and vice versa.

Other objects, features, aspects and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

Detailed Description

Specific examples of the present invention will now be described with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these examples are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The terminology used in the detailed description of the examples illustrated in the accompanying drawings is not intended to be limiting of the invention. In the drawings, like numbering represents like elements.

Fig. 1 is a schematic view of a carton package 100 for a liquid consumable, the carton package 100 comprising a top panel (T), a bottom panel (B) and a body 101 extending between the top panel (T) and the bottom panel (B). The main body 101 includes a Front Panel (FP), a rear panel (BP), a Left Panel (LP), and a Right Panel (RP). The Left Panel (LP) is shown in the front view of fig. 3. Each of the Front Panel (FP), the rear panel (BP), the Left Panel (LP) and the Right Panel (RP) extends from the bottom panel (B) to the top panel (T). The Front Panel (FP) is connected to the Top Panel (TP) along a Front Top Edge (FTE). The Left Panel (LP) is connected to the Top Panel (TP) along the Left Top Edge (LTE). The Right Panel (RP) is connected to the Top Panel (TP) along the Right Top Edge (RTE). Turning to the example of fig. 4, a Front Top Edge (FTE) extends between the Left Panel (LP) and the Right Panel (RP) and has a center point 102. The top left edge (LTE) extends between the Front Panel (FP) and the Back Panel (BP) and has a center point 103. The carton package 100 comprises an opening device 108 arranged on the top panel (T). The opening device 108 has a center point 109, the center point 109 having an offset distance 104 from a first line 105 that is perpendicular to the Front Top Edge (FTE) and extends through its center point 102, as shown in fig. 4. Thus, the opening device 108 is located on the top panel (T) with an offset distance 104 from the first centerline 105. Fig. 5a to 5f show different examples of such offsets, which will be described in further detail below. Further, the area of the top panel (T) is larger than the area of the bottom panel (B). Having the opening device 108 with an off-center position on the top panel (T) while having the top panel (T) with a larger area than the bottom panel (B) facilitates removal of the filled product because a larger opening can be accommodated in the top panel area while the offset position of the opening device improves the degree of control in pouring the filled product from the carton package 100. A synergistic effect of the advantageous properties is provided from the user's perspective, the user being able to remove the contents from the carton package 100 more quickly without compromising the degree of control in pouring the contents from the opening device 108. The offset position of the opening device 108 with respect to the first line 105 passing through the center point 102 of the Front Top Edge (FTE) allows to place the opening device 108 closer to the Left Panel (LP). Accordingly, while intuitively grasping the carton package 100 from the side by engaging (engaging) the Right Panel (RP), the contents can be conveniently poured from the opposite side, i.e., from the opening device 108 located near the Left Panel (LP). Thus improving the ease of handling when pouring the contents from the carton package 100. Grasping the carton package 100 from the right and subsequently pouring the contents from the carton package 100 by rotating the carton package 100 about the first line 105 is advantageous compared to rotating the carton package 100 about the indicated second line 107 (fig. 4). The latter rotation provides less stability during the pouring action. Thus, having the offset distance 104 towards the Left Top Edge (LTE) and the Right Panel (RP) as described above allows pouring the contents from the opening device 108 with a reduced risk of bringing the contents into contact with the top panel (T). In other words, the offset distance 104 reduces the distance between the opening device 108 and the Left Top Edge (LTE), thereby reducing the surface area of the top panel (T) between the opening device 108 and the Left Top Edge (LTE). The offset distance 104 also reduces the angle the carton package 100 needs to be rotated about the first line 105 in order to remove the remaining final contents of the carton package 100. In other words, the carton package 100 has to be rotated such that the contents flow through the packaging material of the carton package 100 extending between the opening device 108 and the Left Top Edge (LTE). Thus, reducing the above-mentioned distance will reduce the angle at which the carton package 100 needs to be rotated in order to empty the contents therefrom. Thus facilitating handling of the carton package 100.

The first line 105 may extend from the center point 102 to the opposite rear top edge (BTE) of the top panel (T) such that the first line 105 divides the total area of the top panel (T) into two parts, as shown in fig. 5 a. The opening device 108 covers the Opening Area (OA) of the top panel (T). The portion of the Open Area (OA) contained in the first part 111 of the above two parts may be in the range of 60-100%. For example, if the opening device 108 is located in the center of the first line 105 without the offset distance 104, half of the Open Area (OA) will be contained within the first portion 111. Thus, the opening means 108 may be offset with respect to the first line 105 such that a larger part of the Opening Area (OA) is comprised within the first portion 111. The first portion 111 of the top panel (T) is defined by a Left Top Edge (LTE), a first line 105, a Front Top Edge (FTE), and a rear top edge (BTE). Fig. 5a shows one example of the portion of the Open Area (OA) that overlaps with the first portion 111, and it will be appreciated that various portions in the range of 60-100% provide the advantageous benefits described above by facilitating pouring of the contents from the carton package 100. Fig. 4 and 5b show an example in which 100% of the Open Area (OA) is contained in the first portion 111. This may make it particularly convenient to pour the contents from the carton package 100, as the distance between the Left Top Edge (LTE) and the opening device 108 is further reduced. The offset distance 104, and the associated portion of the Open Area (OA) that overlaps the first portion 111, may be varied to optimize the handling of the carton package 100 for various types of carton package designs and filled products.

The center point 109 of the opening means 108 may have an offset distance 106 from a second line 107 perpendicular to the top left edge (LTE) and extending through its center point 103, as shown for example in fig. 4. Accordingly, the opening devices 108 may also be offset toward the Front Panel (FP) to further reduce the area of the top panel (T) extending between the opening devices 108 and the top left edge (LTE) and the top front edge (FTE) of the top panel (T). This allows for further facilitating pouring of the contents from the carton package 100 while minimizing the risk of the contents flowing onto the top panel (T) and minimizing the rotation of the carton package 100 about the first line 105 in order to empty the last contents remaining in the carton package 100. Thus, the user's control of pouring is improved, while the advantage of an increased size of the opening means 108, i.e. a faster removal of the content, can be utilized.

The second line 107 may extend from the central point 103 to the opposite Right Top Edge (RTE) of the top panel (T) such that the second line 107 divides the total area of the top panel (T) into two parts, as shown in fig. 5 c. The opening device 108 covers the Opening Area (OA) of the top panel (T). The portion of the Open Area (OA) contained in the first (112) of the two portions may be in the range of 60-100%. Thus, the opening means 108 may be offset with respect to the second line 107 such that a larger part of the Opening Area (OA) is contained within the first portion 112. The first portion 112 of the top panel (T) is defined by a Left Top Edge (LTE), a second line 107, a Front Top Edge (FTE), and a Right Top Edge (RTE). Fig. 5c shows one example of the portion of the Open Area (OA) that overlaps with the first portion 112, and it will be appreciated that various portions in the range of 60-100% provide the advantageous benefits described above by facilitating pouring of the contents from the carton package 100. Fig. 5d shows an example in which 100% of the Open Area (OA) is contained in the first portion 112. This may make it particularly convenient to pour the contents from the carton package 100, as the distance between the Front Top Edge (FTE) and the opening device 108 is further reduced. The offset distance 106, and the associated portion of the Open Area (OA) that overlaps the first portion 112, may be varied to optimize the handling of the carton package 100 for various types of carton package designs and filled products.

The first and

second lines

105, 107 may extend from the central point 102 and the central point 103, respectively, to intersect at the midpoint 110 of the top panel, such that the first and

second lines

105, 107 divide the total area of the top panel (T) into four portions, as shown in fig. 5 e. The opening device 108 covers the Opening Area (OA) of the top panel (T). The portion of the Open Area (OA) contained within the first portion 113 of the four portions may be in the range of 60-100%. Thus, the opening device 108 may be offset with respect to both the first and

second lines

105, 107 such that a larger portion of the Open Area (OA) is contained within the first portion 113. The first portion 113 of the top panel (T) is defined by a Left Top Edge (LTE), a first line 105, a second line 107, and a Front Top Edge (FTE). Fig. 5e shows one example of the portion of the Open Area (OA) that overlaps with the first portion 113, and it will be appreciated that various portions in the range of 60-100% provide the advantageous benefits described above by facilitating pouring of the contents from the carton package 100. Fig. 5f shows an example where 100% of the Open Area (OA) is contained in the first portion 113. This may make the pouring of contents from the carton package 100 particularly convenient as the distance between the Front Top Edge (FTE) and the opening device 108, and the distance between the Left Top Edge (LTE) and the opening device 108, is further reduced. The offset distances 104 and 106, and the associated portions of the Open Area (OA) that overlap the first portion 113, may be varied to optimize the handling of the carton package 100 for various types of carton package designs and filled products. It will be appreciated that the opening means 108 may be shifted into any of the

aforementioned portions

111, 112, 113 by varying amounts while providing the advantages described above. In some examples, the top panel (T) may be inclined toward the Front Panel (FP), as shown in fig. 2. In this case, the opening device 108 is advantageously arranged with an offset 106 towards the Front Top Edge (FTE) such that a limited or no portion of the opening device 108 extends above the rear top edge (BTE) of the carton package 100, as schematically shown in fig. 6. This reduces the risk of damaging the opening arrangement 108 during stacking and transport of e.g. carton packages 100.

Therefore, the height (h) of the Back Panel (BP) from the Back Bottom Edge (BBE) to the Back Top Edge (BTE)_b) Can be greater than the height (h) of the Front Panel (FP) from the Front Bottom Edge (FBE) to the Front Top Edge (FTE)_f) As shown in fig. 2. Having a sloping roof panel (T) also increases the area of the roof panel (T). The top panel (T) may thus accommodate a larger opening device 108 for faster removal of contents, particularly high viscosity contents, from the carton package 100. However, it is envisaged that the area of the top panel (T) which is greater than the area of the bottom panel (B) is provided by other configurations, for example by angling or bending any of the panels (FP, BP, LP, RP). However, the inclined top panel (T) may provide a particularly stable carton package 100, while allowing for an increased area of the top panel (T) and protection of the opening device 108.

The Front Top Edge (FTE) may be longer than the Left Top Edge (LTE), as shown in the example of fig. 4. This provides a narrower Right Panel (RP) and Left Panel (LP) relative to the Front Panel (FP) and rear panel (BP), which in turn provides a narrow and intuitive gripping portion of the carton package 100 where a user can place his hands when quickly engaged to grip the package 100. As described above, biasing the opening device 108 toward the opposing Left Panel (LP) by engaging the Right Panel (RP) with a grip allows for ease of pouring the contents of the carton package 100.

The carton package 100 may include at least one rounded edge 114 extending between the top panel (T) and the bottom panel (B), as shown in the example of fig. 9. The width of the rounded edge 114 may reach a maximum at the midpoint of the carton package 100 and then gradually decrease toward the top panel (T) and the bottom panel (B), as shown in fig. 9. The rounded edges 114 are used to facilitate grasping of the carton package 100 and manipulation of the shape of the package 100, such as compressing the carton package 100. The rounded edge 114 may be provided at any edge of the carton package extending from the bottom panel (B) to the top panel (T). Fig. 10 shows an example of a carton blank 200 having panel portions 114' for providing such rounded edges 114 of the packaging container 100.

Fig. 7a is a schematic illustration of a carton blank 200 for the carton package 100. The carton blank 200 includes a first longitudinal crease line 301 defining a Front Left Edge (FLE) and a Left Top Edge (LTE) of the carton package 100. The second longitudinal crease line 302 defines the Front Right Edge (FRE) and the Right Top Edge (RTE) of the carton package 100. The carton blank 200 includes a front panel portion (FP), a rear panel portion (BP), a left panel portion (LP), and a right panel portion (RP). The carton blank 200 further includes a first transverse crease line 303, the first transverse crease line 303 including a first portion 303' defining a Front Top Edge (FTE), and second portions 303 ", 303" ' at opposite ends of the first portion 303' defining upper oblique side portions of the left panel portion (LP) and the right panel portion (RP). The second portions 303 ", 303" 'of the first transverse crease line 303 are angled with respect to their first portions 303', as shown in fig. 7 a. The front panel part (FP) is connected to the top panel part (T) along a Front Top Edge (FTE)₁)。

FIG. 7b is the top panel portion (T) of the carton blank 200₁) Detailed view of (a). The Front Top Edge (FTE) extends between the first longitudinal crease line 301 and the second longitudinal crease line 302 and has a center point 102. The centre point 102 is shown in fig. 7 b. The carton blank 200 includes a top panel portion (T) disposed in the top panel portion₁) And a removable opening portion 108'. The removable opening portion 108' is for receiving the opening device 108. The removable opening portion 108 'has a center point 109' with an offset distance 104 from a first line 105 that is perpendicular to the Front Top Edge (FTE) and extends through its center point 102, as shown in fig. 7 b. Having the removable opening portion 108' arranged to have an offset distance 104 from the first line 105 through the center of the Front Top Edge (FTE) results in the formation of a carton package 100 wherein the blank 200 has the advantageous benefits as described above with respect to the carton package 100 and fig. 1-6. Angling the second portions 303 ", 303" ' of the first transverse crease line 303 relative to its first portion 303' provides the advantageous benefit of having an increased top area and cooperating with the offset opening portion 108', as described above with respect to the carton package 100.

FIGS. 8 a-8 f show the top panel portion (T)₁) Examples of (2). The first line 105 may extend from the above-mentioned center point 102 to the top panel part (T)₁) Such that the first line 102 connects the top panel portion (T) to the opposite rear top edge portion (BTE') of (a)₁) Is divided into two parts as shown in fig. 8 a. The removable opening portion 108' covers the top panel portion (T)₁) Is provided in the opening area (OA'). The portion of the opening area (OA') included in the first part 111 of the above two parts may be in the range of 60-100%. Fig. 8a shows one example of the portion of the opening area (OA') that overlaps the first portion 111, and it will be appreciated that various portions in the range of 60-100% provide the advantageous benefits described above by facilitating pouring of the contents from the carton package 100. Fig. 8b shows an example in which 100% of the open area (OA') is contained in the first portion 111. This may make pouring of the contents from the carton package 100 particularly convenient.

The center point 109 'of the removable opening portion 108' may have an offset distance 106 from a second line 107 perpendicular to the top left edge (LTE) and extending through its center point 103, as shown for example in fig. 8 c. Thus, the blank 200 provides an opening portion 108', which opening portion 108' is also offset towards the Front Panel (FP) of the carton package 100, as described above with respect to fig. 1-6.

The second line 107 may extend from the center point 103 to the top panel portion (T)₁) Such that the second line 107 divides the top panel portion (T)₁) Is divided into two parts as shown in fig. 8 c. The removable opening portion 108' covers the top panel portion (T)₁) Is provided in the opening area (OA'). The portion of the open area (OA') contained in the first part 112 of the aforementioned two parts may be in the range of 60-100%. Fig. 8c shows one example of the portion of the open area (OA') that overlaps the first portion 112, and it will be appreciated that various portions in the range of 60-100% provide the advantageous benefits described above by facilitating pouring of the contents from the carton package 100. Fig. 8d shows an example in which 100% of the open area (OA') is contained in the first portion 112. This may make pouring of the contents from the carton package 100 particularly convenient.

First and

second lines

105, 107 may extend from center point 102 and center point 103, respectively, to be on the top panel portion (T)₁) Such that the first line 105 and the second line 107 will be part of the top panel (T)₁) Is divided into four parts as shown in the example of fig. 8 e. The removable opening portion 108' covers the top panel portion (T)₁) Is provided in the opening area (OA'). The portion of the opening area (OA') included in the first portion 113 of the above-described four portions may be in the range of 60-100%. Fig. 8e shows one example of the portion of the opening area (OA') that overlaps the first portion 113, and it will be appreciated that various portions in the range of 60-100% provide the advantageous benefits described above by facilitating pouring of the contents from the carton package 100. Fig. 8f shows an example in which 100% of the open area (OA') is contained in the first portion 113. Since the distance between the Front Top Edge (FTE) and the opening portion 108', and the distance between the Left Top Edge (LTE) and the opening portion 108' are further reduced, this may beSo as to particularly facilitate pouring of the contents from the carton package 100.

Turning to fig. 7a, a right panel portion (RP) may extend between the first longitudinal crease line 301 and the third longitudinal crease line 304. The right panel part (RP) has a first length (h) along the third longitudinal crease line 304 between the first transverse crease line 303 and the second transverse crease line 305₁). In particular, second transverse crease line 305 defines a Front Bottom Edge (FBE) and a rear bottom edge (BBE) of package 11, as shown in fig. 1. The right panel part (RP) has a second length (h) along the first longitudinal crease line 301 between the first transverse crease line 303 and the second transverse crease line 305₂). First length (h)₁) May be longer than the second length (h)₂) Long as shown in fig. 7 a. Thus, the carton blank 200 is used to form a carton package 100 having a sloping top panel (T), as shown in fig. 2, with the advantageous benefits described above with respect to the carton package 100.

The Left Top Edge (LTE) may have a shorter length than the Front Top Edge (FTE), as shown for example in fig. 7 b. This allows the paperboard package 100 to have narrower Right (RP) and Left Panels (LP) relative to the Front (FP) and rear (BP) panels, which in turn provides a narrow and intuitive grip portion of the carton package 100 during use. As described above, biasing the opening device 108' toward the opposing Left Panel (LP) by engaging the Right Panel (RP) with a grip allows for ease of pouring the contents of the carton package 100.

The invention has been described above with reference to specific examples. However, other examples than the above are equally possible within the scope of the invention. The different features and steps of the invention may be combined in other combinations than those described. The scope of the invention is limited only by the appended claims.

More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the teachings of the present invention is/are used.
