Description

"FINGER TAB" FIELD OF THE INVENTION

[0001] The present invention relates to a box comprising a finger flap for an openable rim.

BACKGROUND OF THE INVENTION

[0002] Rectangular boxes that contain, for example, a tube of toothpaste, are ubiquitous. Users often open the box to access the contents of the box from either end (that is, the smallest dimension on the sides). Users report frustration when opening a side panel and additional frustration at having to sometimes shake the box to push the contents out of the box (given the relatively small opening that is provided by the side panel). There is a need for users to access the toothpaste tube contained in the cardboard box more easily. In addition, there is a need for manufacturers to present a special packaging and opening experience to users to provide a special product and experience.

[0003] In the approach to solve the need is the use of a flange that is on one or more sides of the box, that is, along the length. In one example, the rim extends across the top and front sides of the box. The use of a finger flap occurs to initiate the opening of the rim. However, the finger flap must be relatively easy to open by the user, however, it must have sufficient structural integrity not to be opened prematurely (for example, during manufacture, transportation or handling). If the finger flap opens prematurely, the potential user may see the entire product in a negative way, either due to lack of quality or because it opens allowing contaminants to enter the box. However, if the finger tab is difficult to open, the user may be frustrated by the experience of the packaging and may see the entire product negatively due to lack of quality.

SUMMARY OF THE INVENTION

[0004] The present invention is based on the surprising discovery, at least in part, that a finger flap comprising a first intersection, the first intersection being formed by a first half-cut perforated line that crosses a first perforation that it is at least 1 mm in length, provides the finger flap that is easy to open by the user, but does not open prematurely (under typical conditions of transport and handling). Consequently, an aspect of the invention provides a box comprising a finger flap to initiate the opening of a flange, the finger flap comprising a first intersection, the first intersection being formed by a first perforated line of medium cut that crosses a first perforation. Another aspect provides a method for opening a box which comprises the step of pressing the finger inward with the finger inward to hold and then opening the rim of the box to expose the inside of the box. Another aspect provides the use of a flap for the finger to open a rim of a box, the rim can be opened from a front side and from a contiguous top side, which is easy to open by the user, however, it does not open prematurely (under typical conditions of transport and handling).

[0005] These and other aspects, as well as characteristics and advantages of specific modalities, will become evident to those skilled in the art, from the reading of the present revelation.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The following text presents a broad description of numerous different modalities of the present revelation. The detailed description should only be interpreted as an example, and it does not describe all possible modalities, since the description of all possible modalities is impractical, if not impossible. It should be understood that any resource, characteristic, component, composition, ingredient, product, step or methodology described herein can be totally or partially deleted, combined with, or replaced by any other resource, characteristic, component, composition, ingredient, product, step or methodology described here. Numerous alternative modalities may be implemented with the use of current technology or technology developed after the date of filing this patent, which would still be within the scope of the claims.

[0017] Figure 1 is a perspective view of a box (1) comprising a finger flap (3) to initiate the opening of a flange (5). A longitudinal geometric axis (1) runs along the length of the box (10). The box is preferably rectangular, preferably made of cardboard and preferably has dimensions that are typical of those that contain oral care products, such as toothpaste. For example, the toothpaste tube may contain 5 g to 300 g of toothpaste, preferably 80 g to 250 g; examples without limitation include 90 g, 140 g and 300 g of toothpaste.

[0018] The rim (5) is preferably made of cardboard, and more preferably, the box (1) is made of cardboard.

Cardboard has a density of 50 g / m2 to 700 g / m2, preferably 100 g / m2 to 600 g / m2, more preferably 200 g / m2 to 500 g / m2, most preferably 300 g / m2 to 400 g / m2. The cardboard can be 100% virgin material, 100% recycled material, or a combination thereof, preferably the cardboard is virgin material.

The six-sided rectangular box (1) has the following dimensions: a box length (3) (measured along the longitudinal geometric axis (10)) is 10 cm to 40 cm, preferably 18 cm to 30 cm.

The width of the box (1) is 3 cm to 9 cm, preferably 4 cm to 8 cm.

The height of the box (3) is 2 cm to 8 cm, preferably 3 cm to 7 cm.

The internal volume of the box (1), when devoid of content, is 300 cm3 to 900 cm3, preferably 400 cm3 to 800 cm3. Although not shown, the box preferably contains a mouth care product (eg toothbrush, toothpaste, combination thereof) in the internal volume, most preferably the mouth care product is a tube of toothpaste.

The rim (5) of the box (1) is formed as part of the front side (4) and the top side (2), the front and top sides (4, 2) being contiguous.

The front and top sides (2) are along the longitudinal geometric axis (10). These sides (4, 2) are distinguished from the left and right end sides (18, 8), which are in a plane orthogonal to the longitudinal geometric axis (10). The finger flap (3), or more specifically the finger flap body (2), is located on the front side (4), preferably located in the middle third of the length or width dimension (on the front side (4) )), more preferably, both length and width dimensions (on the front side (4)). The edge (5) is defined by a first perforated line (11) and a second perforated line (12) which are opposite each other. Preferably, the box (1) has bilateral symmetry along an orthogonal plane and at a midpoint for the longitudinal geometric axis (10). It is in this plane of bilateral symmetry that the first and second lines of symmetry (11, 12) are opposite to each other. There is a folding edge (14), between the top side interface (2) and the rear side (16), which is hinged to the rim (5) by opening. The rear side (16) is opposite to the front side (4). The top side (2) is between the rear side (16) and the front side (4). The first perforated line (11) and the second perforated line (12) converge on the front side (4) for the finger tab (3). The rim (5) can occupy from 60% to 100%, preferably from 70% to 95% of the surface area on the top side (2) of the box (1). In addition, the flange (5) can additionally occupy 15% to 95%, preferably 20 to 90% of the surface area on the front side (4) of the housing (1). The rim (5) extends contiguously from the top and front sides (2, 4).

[0019] The user presses with a finger (that is, with a finger) the finger flap (3) inwards (towards the inside of the box (1) to break the pressing flap from the front side (4) to hold an edge, now exposed, of the edge (5) and pull the edge (5) that breaks the first and second perforated lines (11, 12) to expose the inside of the box (5) and the product contained therein ( for example, the mouth care product, such as a toothpaste tube (not shown). The rim (5) can be opened from the front side (4) and the contiguous top side (2). (3) and the rim (2) are easy to open by the user, however, they do not open prematurely (under typical conditions of transport and handling).

[0020] Without wishing to be bound by theory, this relatively central location of the finger flap (3) can help in the balance between ease of opening and robust integrity (during typical transport and handling) given the observation that pressure, upon opening from the flap to the finger, it will generally be the same along the front side of the box (in relation to being tilted towards an edge). In addition, this need for balance is particularly pronounced in the cardboard, given the relatively minimal thickness and properties of the cardboard material.

[0021] With respect to Figure 2, the left and right perforated lines (11, 12) have at least a portion of a half cut perforated line close to the first and second intersections (31, 32), respectively. The perforated line can include any suitable type which includes, for example, perforation lines, die cut lines, or marking line, to facilitate the opening of the flange (5). Preferably, the entire left and right perforated lines (11, 12) are half cut perforated line from the folding edge (14) to the first and second intersections (31, 32). A "half-cut perforation line" means a perforation line formed when a first die that has a first blade cuts the precursor of the cardboard box (for example, the cardboard) to about half its thickness and a second opposite die that has a second blade also cuts the precursor of the cardboard box to about half its thickness.

The cuts made by the respective blades are made in a transversal direction in relation to the thickness of the precursor of the cardboard box.

The cuts (for the first and second blades) are not made directly opposite each other, but instead, at a distance of 2 mm to 10 mm, preferably from 3 mm to 8 mm, with more preferably from 4 mm to 7 mm, alternatively about 4 mm, 5 mm or 6 mm.

Consequently, each cut line (from the first and second blades) will generally imitate the other (but at the indicated distances). The user, when unfolding and opening the flange (5), delaminates the box precursor between the two opposite cut lines (from the half cut perforation line). In one example, the precursor to the cardboard box is cardboard weighing 350 grams per square meter.

Preferably, the lengths of the first and second half-cut perforated lines (11, 12) are each independently at least 1 cm, preferably at least 2 cm, more preferably at least 3 cm, as measured at from each respective first and second intersection points (31, 32). A person skilled in the art will understand that the distances between the first and second blades (for example, 5 mm) will converge (ie, distances between blades will decrease) as the perforated line (11, 12) meets the first and second intersections (31, 32), respectively.

An advantage of a half-perforated line is the smooth finish provided on the surface of the box (1), thereby providing designs and artwork that appear to be of a high quality, different than it would be if it were available otherwise from other types perforated lines that otherwise deform the smooth finish of the cardboard.

[0022] The finger flap (5) which comprises a first intersection (31) is formed by a first half-cut perforated line (11) which crosses a first perforation (21), wherein the first perforation has at least 2 mm. Similarly, a second intersection (32) is formed by a second half-cut perforated line (12) that crosses a second perforation (22). The first and second intersections (31, 32) are opposite to each other. At least one connection (7A) occurs between the first and second perforations (21, 22) to form a first perforation line (41). "Perforation" made a cut through the thickness of one side, that is, cardboard, of the box (1). Preferably, the cut is made at an angle perpendicular to the lateral surface. "Bonding" means that portion of the side, that is, cardboard, along the perforation line, which is not cut. A perforation line can be linear or arched or a combination thereof.

[0023] Preferably, the length of the first perforation (21) is from 2 mm to 7 mm, preferably greater than 2 mm to 5 mm, more preferably from 2.5 mm to 4.5 mm. Examples without limitation include 3, 3.5, 3.8, 4.1, 4.5 mm in length. Preferably, the length of the second perforation (22) is at least 2 mm, preferably from 2 mm to 7 mm, more preferably greater than 2 mm to 5 mm, more preferably 2.5 mm to 4, 5 mm. Examples without limitation include 3, 3.5, 3.8, 4.1, 4.5 mm in length.

Based on observation from comparative samples (discussed below) and without wishing to be bound by theory, the length of the first and second perforations (21, 22) and that of the intersection of the first and second intersections (31, 32) are important factors in the finger flap (3) that demonstrate the balance between ease of opening and prevention of premature opening (typical transport and handling).

[0024] The first perforation line (41) can additionally comprise a plurality of additional perforations (70A to 70E), preferably from 2 to 16 additional perforations, more preferably from 3 to 8 additional perforations. Preferably each of the plurality of additional perforations (70A to 70E) is, independently, from 0.5 mm to 6 mm, preferably from 1 to 5 mm, more preferably 2 to 4 mm in length. Preferably, each of the plurality of additional perforations (70A to 70E) has the same length. In the example without limitation illustrated in Figure 2, there are a total of seven perforations (ie, first, second (21, 22) that are 3.8 mm in length; and additional perforations (70A to 70E)) that each have , 3 mm in length.

[0025] Preferably, the length of the at least one connection (7A) is 0.1 mm to 3 mm, preferably 0.3 mm to 2 mm, more preferably 0.5 mm to 1.5 mm , most preferably from 0.7 mm to 1.3 mm. Preferably, the first perforation line (41) additionally comprises a plurality of additional connections (7B to 7F). Such plurality of additional bonds (7B to 7F) can be from 2 to 18 additional bonds, more preferably from 3 to 9 additional bonds. Preferably, each of the plurality of additional connections (7B to 7F) is independently 0.1 mm to 3 mm, preferably 0.3 mm to 2 mm, more preferably 0.5 mm to 1.5 mm in length. In an example without limitation illustrated in Figure 2, there are a total of six connections (7A to 7F) (from the first perforation line (41) each is 1 mm in length.

[0026] The linear distance between the first intersection (31) and the second intersection (32) is 10 mm to 70 mm, preferably 20 mm to 50 mm, more preferably 24 mm to 34 mm. For example, the distance between the first intersection (31) and the second intersection (32) is 25, 26, 27, 28, 28.6, 29, 30 or 31 mm, preferably 28.6 mm. The first perforation line (41) between the first and the second intersections (31, 32) is substantially linear, preferably linear.

[0027] Preferably, the finger tab (3) additionally comprises a third perforation (33) which crosses at the first intersection (31), and more preferably a fourth perforation (44) which crosses at the second intersection (32). At least a second connection (9A) is between the third and fourth perforations (33, 44, respectively) to form a second perforation line (42). Preferably, the first perforation line (41) is close to the lip (5) while the second perforation line (42) is distal to the lip (5) (i.e., close to a non-lip region (6)). Preferably, the second perforation line (42) is non-linear, preferably arcuate. Arc can have constant radius or inconstant radius. A regular arc has a constant radius. More preferably, the second perforation line (32) is a regular arc having a radius from 10 mm to 30 mm, preferably from 12 mm to 24 mm, more preferably from 15 mm to 21 mm; the central point of the radius being on the edge (5). Examples without radius limitation are 16, 17, 18, 18.4, 19 or 20 mm.

[0028] The second perforation line (42) additionally preferably comprises a plurality of additional connections (9B to 9E), preferably from 2 to 12 additional connections, more preferably from 3 to 5 additional connections. Preferably, each of the plurality of additional connections is independently 0.1 mm to 6 mm, preferably 0.2 mm to 2 mm, more preferably 0.5 mm to 1.5 mm in length (the length being measured along the second drilling line). For example, if the second perforation line is arched, then the length is measured along the arc. In the example without limitation shown in Figure 2, there are a total of 5 connections, that is, 9A to 9E (from the second perforation line (42)) each is 1 mm in length (along the arc).

[0029] The second perforation line (42) additionally preferably comprises a plurality of perforations (90A to 90D), preferably from 2 to 12 additional perforations, more preferably from 3 to 5 additional perforations. Preferably, each of the plurality of additional perforations is independently 4 mm to 7 mm, preferably 4.5 mm to 6.5 mm, more preferably 5 mm to 6 mm in length (being length is measured along the second drilling line). The additional perforation may have a length, as an example without limitation, of 4 mm, 5 mm, 5.5 mm, 6 mm, or 7 mm. The second perforation line (42) has a length of 15 mm to 50 mm, preferably from 20 mm to 45 mm, more preferably from 28 mm to 38 mm. Examples without limiting this length are 30 mm, 33 mm, 33.8 mm and 36 mm. The length is measured along the second perforation line (42). For example, if the second perforation line (42) is arched, then the length is measured along the arc. In the example without limitation shown in Figure 2, there are a total of seven perforations (ie, first, second (21, 22) each are 3.8 mm; and additional perforations (70A to 70E)) that each have 3 mm in length).

[0030] Angles are formed at the first and second intersections (31, 32). A first alpha angle (51) will be formed on the rim (5) between the first half-cut perforated line (11) and the first perforation (21), and be 120 degrees to 200 degrees, preferably 140 degrees to 180 degrees , more preferably from 150 degrees to 175 degrees. Similarly, a second alpha angle (52) is preferably formed at the rim (5) between the second half-cut perforated line (12) and the second perforation (22), and is preferably 140 degrees to 190 degrees from 150 degrees to 180 degrees, more preferably from 160 degrees to 175 degrees. Preferably, the first and the second alpha angles (51, 52) are the same. In the example without limitation, the first alpha angle (51) and the second alpha angle (52) are each 150, 160, 170, 180 or 190 degrees, preferably 170 degrees.

[0031] A first beta angle (61) is formed between the first half-cut perforated line (11) and the third perforation (33), and is 110 degrees to 170 degrees, preferably 120 degrees to 160 degrees, with more preferably 130 degrees to 150 degrees. Similarly, a second beta angle (62) is preferably formed between the second half-cut perforated line (12) and the fourth perforation (44), and is 110 degrees to 170 degrees, preferably 120 degrees to 160 degrees , more preferably 130 degrees to 150 degrees. Preferably, the first and second beta angles (61, 62) are the same. In the example without limitation, the first beta angle (61) and the second beta angle (62) are each 120, 130, 140, 150 or 160 degrees, preferably 140 degrees.

[0032] A first theta angle (71) is formed between the first perforation (21) and the third perforation (33), and is 10 degrees to 70 degrees, preferably 20 degrees to 60 degrees, more preferably 30 degrees to 50 degrees. Similarly, a second theta angle (72) is preferably formed between the second perforation (22) and the fourth perforation (44), and is 10 degrees to 70 degrees, preferably 20 degrees to 60 degrees, with more preferably 30 to 50 degrees. Preferably, the first and second theta angles (71, 72) are the same. In an example without limitation, the first theta angle (71) and the second theta angle (72) are each 30, 40, 50, 60 or 70 degrees, preferably 50 degrees.

[0033] The sum of the first alpha angle (51), first beta angle (61) and first theta angle (71) is equal to 360 degrees. If present, the sum of the second alpha angle (51), second beta angle (61) and second theta angle (71) is also equal to 360 degrees. Preferably, the finger tab (3) has bilateral symmetry (in an orthogonal plane and a midpoint for the longitudinal geometric axis (10)).

[0034] A body (2) of the finger flap (3) can be defined by the circumscribed portion between the first and the second intersection points (31, 32) and the first and second perforation lines (41, 42) . Thus, the body (2) preferably has an area of 60 mm2 to 210 mm2, preferably from 90 mm2 to 180 mm2, more preferably from 110 mm2 to 160 mm2. Examples without limiting the body area (2) of the flap to the finger (3) include 110 mm2, 120 mm2, 130 mm2, 140 mm2, 150 mm2, or 160 mm2. Examples

[0035] User data (through consumer testing) that compares the box of the invention and that of comparative examples are summarized. Stacking transport tests for the invention box are also summarized. The box comprising the finger tab of Figures 1 and 2 is an example of the present invention. The box of the invention is compared to the comparative examples (A to G) of Figures 4 to 9. The dimensions of the box (229 mm x 55 mm x 44 mm), the type of cardboard (ie 350 g / m2) of material virgin, and half-cut perforated line (opposite blades separated by 5 mm) that define the rim, are the same for each of the boxes (that is, of the invention and comparative), except for the finger flap.

[0036] The finger flap (3) of the invention of Figure 2 comprises a first intersection (31) formed by a first half-cut perforated line (11) that crosses a first perforation (21) with the perforation having 3, 8 mm long and the connection immediately adjacent (7A) to the first hole (21) is 1 mm long. A second intersection (32) is formed by a second half-cut perforated line (12) which crosses a second perforation (22) which is 3.8 mm in length. A connection (7F) immediately adjacent to the second perforation (22) is 1 mm in length. A first (linear) perforation line (41) is between said first and second intersections (31, 32). The first perforation line (41) has five more perforations (70A to 70E), each of which is about 3 mm in length; and the linear perforation line (41) has a total of six connections (7A to 7F), each of which is about 1 mm in length. The finger tab of the invention (3) of Figure 2 also has a second (arcuate) perforation line (42), in which the third perforation line (33) and the fourth perforation line (44) cross the first intersection (31) and the second intersection (32), respectively.

[0037] A stacking test and transport tests (two types) are conducted on this box of the invention and the finger tab has remained intact despite the compression and other stresses associated with these tests. A transport test is aimed at mass production. Several carton packages (for example, for a retail customer) are stacked in a truck container and then transported by truck from one location to another, and then the boxes are inspected for premature opening. Another transportation test is an ISTA e-commerce test. Results of these tests indicate that the boxes of the invention did not open prematurely.

[0038] Figure 3 is a tab for the comparative finger (103). A first intersection (131) is formed by a first half-cut perforated line (111) that crosses a score line (141). Notably, there are no perforations or connections on the scoring line (142). A score line is made by pressing a thin metal edge (but not a sharp knife) on the cardboard so that a compressed crease is formed to facilitate folding / hanging. A second intersection (132) is formed by a second half-cut perforated line (112) that crosses said scoring line (141). The score line (141) is between said first and second intersections (131, 132). The finger tab (103) of example A in the present invention also has a (arcuate) perforation line (142), wherein the third perforation line (133) and the fourth perforation line (144) cross the first intersection (131) and the second intersection (132), respectively. This perforation line (142) in example A is analogous to the second perforation line (43) in the example of the invention. The perforation line (142) has a total of six perforations (133, 190A to 190D, 144) each are 4.8 mm in length (measured along the arc) and a total of five connections (109A to 109E) between them, each one being 1 mm in length (measured along the arc). Results indicate that users (through consumer testing) are not able to easily push the flap onto their finger to open the rim. The scoring line provides a very large barrier for users. Consequently, comparative example A in Figure 3 demonstrates the importance of having a first perforation line and a first perforation of at least 1 mm in length.

[0039] Figure 4 is another tab for the comparative finger (203) B. The first and second perforated half-cut lines (211, 212) are analogous to those of the invention (of Figure 2). However, there is notably neither a first intersection nor a second intersection. The first perforation line (241) is essentially a single perforation in the middle third of the first perforation line (241) and connections (207A, 207B) at either end of the first perforation line (241). The second perforation line (242) of this comparative example B is analogous to the second perforation line of the finger flap of the invention except that the third and fourth perforations (233, 244) do not cross what would otherwise be way, the first and second intersections. Results indicate that users (through consumer testing) are not able to easily push the flap onto their finger to open the rim. Consequently, comparative example B in Figure 4 demonstrates the importance of having a first (and second) intersection (or intersections). In addition, the connections (207A, 207B) of the first drilling line (241) are likely to be an additional barrier to ease of opening.

[0040] Figure 5 is another tab for the comparative finger (303) C. Example C is analogous to the previous example B, however, the dimensions of the connections (309A to 309E) and perforations (333, 390A to 390D, 344) second drilling line (342) are different. The first and the second half-cut perforated lines (311, 312) are analogous to those of the invention (of Figure 2). However, there is notably neither a first intersection nor a second intersection. The first perforation line (341) is essentially a single perforation in the middle third of the first perforation line (341) and a connection (307A, 307B) on either side of the first perforation line (341). The second perforation line (341) has a total of six perforations (333, 390A to 390D, 344), each of which is about 4 mm in length (measured along the arc) and a total of five connections (309A to 309E) between these perforations, each of which is about 2 mm in length (with respect to 1 mm, compared to example B). Results indicate that users (through consumer testing) are not able to easily push the flap onto their finger to open the rim. Consequently, comparative example B in Figure 4 demonstrates the importance of having a first (and second) intersection (or intersections). In addition, the connections (207A, 207B) are probably an additional barrier to ease of opening. The greater distance of the connections on the second drilling line also provides a greater additional barrier (compared to example B above).

[0041] Figure 6 is another tab for the comparative finger (403) D. Example D has neither a first intersection nor a second intersection. The first (linear) perforation line (441) and the second (arcuate) perforation line (442) fail to intersect with each other and fail to intersect with the respective half-cut perforated lines (411, 412). There is a gap of about 1 mm at either end of the first perforation line (441) to otherwise cross any respective end of the second perforation line (442). In addition, the first and second half-cut perforated lines (411, 412) also each have a span of about 1 mm to otherwise cross any respective end of the second perforation line (442). The first drilling line (441) has a total of six perforations (421, 470A to 470D, 422), each of which is about 2.8 mm in length, and a total of five connections (407A to 407E) between them, each of which is about 2 mm in length. The second (arcuate) perforation line (442) has a total of five perforations (433, 490A at 490C, 444) each are about 5.2 mm in length (along the arch), and a total of four connections (409A to 409D) between them, each of which is about 2 mm in length (along the arch). Results indicate that users (through consumer testing) are not able to easily push the flap onto their finger to open the rim. Consequently, comparative example D in Figure 6 demonstrates the importance of having a first (and second) intersection (or intersections). In addition, the connection distance of the first drilling line is comparatively longer by 2 mm, which can provide an additional barrier for ease of opening. In addition, the connection distance of the second perforation is also comparatively longer by 2 mm, which can also provide an additional barrier for ease of opening.

[0042] Figure 7 is another tab for the comparative finger (503) E. Example E does not have a first intersection or a second intersection. The first (linear) perforation line (541) fails to cross the second (arcuate) perforation line (542). There is a gap of about 1 mm at either end of the first perforation line (541) to otherwise cross any respective end of the second perforation line (542). In addition, the first and second half-cut perforated lines (511, 512) also each have a span of about 1 mm to otherwise cross any respective end of the second perforation line (542). The first perforation line (541) has a total of six perforations (521, 570A to 570D, 522), each of which is about 2.8 mm in length, and a total of five connections (507A to 507E) between them, each of which is 2 mm in length. The second (arcuate) perforation line (542) has a total of six perforations (533, 590A to 590D, 544) each is about 4.8 mm in length (along the arch), and a total of five connections (509A to 509E) between them, each of which is 1 mm in length (along the arc). Results indicate that users (through consumer testing) are not able to easily push the flap onto their finger to open the rim. Consequently, comparative example E in Figure 7 demonstrates the importance of having a first (and second) intersection (or intersections). In addition, the connection distance of the first drilling line is comparatively longer by 2 mm, which can provide an additional barrier for ease of opening.

[0043] Figure 8 is another tab for the comparative finger (603) F. Example F has neither a first intersection nor a second intersection. The first (linear) drilling line (641) fails to cross the second (arched) drilling line (642). There is a gap of about 1 mm at either end of the first perforation line (641) to otherwise cross any respective end of the second perforation line (642). In addition, the first and second half-cut perforated lines

(611, 612) also each have a span of about 1 mm to otherwise cross any respective end of the second perforation line (642). The first perforation line (641) has a total of six perforations (621, 670A to 670D, 622) each are about 2.8 mm in length, and a total of five connections (607A to 607E) between them, being that each one is 2 mm in length. The second (arcuate) perforation line (642) has a total of six perforations (633, 690A to 690D, 644), each is about 4 mm in length (along the arch), and a total of five connections ( 609A to 609E) between them, each of which is 2 mm in length (along the arch). Results indicate that users (through consumer testing) are not able to easily push the flap onto their finger to open the rim. Consequently, comparative example F in Figure 8 demonstrates the importance of having a first (and second) intersection (or intersections). In addition, the connection distance of the first drilling line is comparatively longer by 2 mm, which can provide an additional barrier for ease of opening. In addition, the connection distance of the second perforation is also comparatively longer by 2 mm, which can also provide an additional barrier for ease of opening.

[0044] Figure 9 is another tab for the comparative finger (703) G. Example G has neither a first intersection nor a second intersection. The first (linear) drill line (741) fails to cross the second (arcuate) drill line (742). There is a gap of about 0.8 mm at either end of the first perforation line (741) to otherwise cross any respective end of the second perforation line (742). In addition, the first and second half-cut perforated lines (711, 712) also each have a span of about 1 mm to otherwise cross any respective end of the second perforation line (742). The first perforation line (741) has a total of seven perforations (721, 770A to 770E, 722), each is 3 mm in length, and a total of six connections (707A to 707F) between them, each of which has 1 mm in length. The second (arcuate) perforation line (742) has a total of six perforations (733, 790A to 790D, 744), each about 4.8 mm in length (along the arch), and a total of five connections (709A to 709E) between them, each one 1 mm long (along the arc). Results indicate that users (through consumer testing) are not able to easily push the flap onto their finger to open the rim. Consequently, comparative example G in Figure 9 demonstrates the importance of having a first (and second) intersection (or intersections).

[0045] In short, the example of the invention in Figure 2 demonstrates the ease of opening (in comparison with the comparative examples A-G), however, it also does not open prematurely during typical transport and handling conditions.
