Container with tamper-evidence, reclosure feature
Abstract
A container formed from an integral blank with a configuration
having a top section and a bottom section attached to each other by
a first line of weakness such that upon the application of
sufficient pressure, the first line of weakness breaks the
attachment of the top section from the bottom section. Upon
breaking the attachment, a cover is formed from the top section
that is hingedly attached to the bottom section at the rear wall
panel. A releasable locking device having a first locking member on
the cover is attached by a second line of weakness to a second
locking member on the front wall portion. The first locking member
and second locking member is in an aligned relationship such that
when the second line of weakness is broken, the cover pivotally
moves to the open position and a recess is formed between the front
panel and side panels and the inner body portion. When the cover
pivotally moves from the open position to the closed position, the
first locking member and the second locking member engage to secure
the inner body portion with cover in a closed relationship.
Optionally, an audible sound is emitted when the first locking
member engages with the second locking member.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to folding carton containers.
More particularly, it is concerned with a sealed container having a
hinged cover that may be opened and subsequently reclosed, i.e.,
"flip-top." Reclosure engages locking members that not only secures
the cover to the container, but results in an audible noise as
well. Additionally, the container includes a tamper-evidence
feature.
BACKGROUND OF THE INVENTION
[0002] Flip top containers are known in the art. Such containers
include a cover or top that is hingedly connected to the top edge
of a wall of the container. It is also known that such containers
may provide various locking mechanisms or devices for securing the
cover to the container after the cover has been initially opened.
In other words, after the seal affixing the cover to the container
has been broken, the locking mechanism holds the cover in a closed
position. Some representative containers of this type are
illustratively disclosed in U.S. Pat. Nos. 3,191,848, 3,378,188,
3,893,614, Re 26,471, 3,294,309, 3,295,742, and 4,215,783.
[0003] Although numerous flip-top containers have been proposed,
most suffer from various disadvantages and shortcomings. Such
disadvantages include complexity of carton making equipment
required and difficulty in opening the cover due to, e.g., tearing,
ripping, bowing, and the like, poor protection of the contents of
the container during transportation and warehouse stacking,
unsatisfactory engagement of locking members because the attachment
of the locking members is too loose or too tight, which can result
in the displacement of product to the outside of the container.
[0004] Thus, as seen, there is a need for a flip-top container that
provides adequate protection during transportation and storage, yet
easily and cleanly opens. What is also needed is a flip-top
container that offers not only a reclosable cover, but provides
tamper-evidence protection as well.
SUMMARY OF THE INVENTION
[0005] A container formed from an integral blank with a
configuration having a top section and a bottom section attached to
each other by a first line of weakness such that upon the
application of sufficient pressure, the first line of weakness
breaks the attachment of the top section from the bottom section.
Upon breaking the attachment, a cover is formed from the top
section that is hingedly attached to the bottom section at the rear
wall panel. A releasable locking device having a first locking
member on the cover is attached by a second line of weakness to a
second locking member on the front wall portion. The first locking
member and second locking member is in an aligned relationship such
that when the second line of weakness is broken, the cover
pivotally moves to the open position and a recess is formed between
the front panel and side panels and the inner body portion. When
the cover pivotally moves from the open position to the closed
position, the first locking member and the second locking member
engage to secure the inner body portion with cover in a closed
relationship. Optionally, an audible sound is emitted when the
first locking member engages with the second locking member.

2.
DETAILED DESCRIPTION OF THE INVENTION
[0010] According to the present invention, a flip-top container is
provided that is formed from an integral, e.g., a single, blank.
The container has bottom, front, rear, and side panels, and a cover
or top. Locking members are provided at the upper edge of the front
wall panel and on the corresponding inner surface of the cover. The
locking members on the wall panel and the cover are in cooperative
relationship to one another to retain the cover in a closed
position after opening.
[0011] The present invention also relates to a unopened flip-top
container having top and bottom sections affixed or linked to one
another by a continuous line of weakness, wherein the container top
section can be pivoted about an integral hinge formed with the rear
wall panel of the bottom section, i.e., hingedly attached. Opening
the unopened container is preferably begun by lifting a grasping
member, which is located on the cover. Opening an unopened
container for the first time results in breaking the continuous
line of weakness between the top and bottom sections, thereby
creating a cover that is hingedly attached to an upper edge of the
rear panel of the container. Thus, any break or other discontinuity
along the continuous line of weakness between the top and bottom
sections, before the container is opened for the first time,
provides an indication of possible package tampering.
[0012] After the container is initially opened, the hingedly
attached cover is maintained in closed position using at least one
locking mechanism or means. Such locking means has a first locking
member and a second locking member, as described more fully below.
Preferably, the separate locking members are initially joined
together by a continuous line of weakness that is broken upon the
initial opening of the cover. After the initial opening and
henceforth, the first and second locking members engage upon
closing, preferably emitting an audible snap sound.
[0013] Referring to FIG. 1, an integral blank 10 as shown is
suitably cut and scored to form container 12 (shown in FIGS. 2 and
3) according to the present invention. Blank 10 includes front wall
panel 20 connected to first cover portion 104 and first bottom
portion 114 by crease score lines 24 and 26, respectively; first
side wall panel 40 connected to second cover portion 102 and second
bottom portion 112 by crease score lines 44 and 46, respectively;
second side wall panel 50 connected to third cover portion 106 and
third bottom portion 116 by crease score lines 54 and 56,
respectively; and back wall panel 30 connected to fourth cover
portion 108 and fourth bottom portion 118 by hinge score line 34
and crease score line 36, respectively. In one embodiment, crease
score lines 44, 46, 24, 26, 54, 56, and 36 and hinge score line 34
are fold lines that have at least one perforation to facilitate the
articulation between the respective cover portions and container
panels.
[0014] First side wall panel 40 is connected to front wall panel 20
by crease line 48. Front wall panel 20 is connected to second side
wall panel 50 by crease line 28. Second side wall panel 50 is
connected to back wall panel 30 by crease line 58.
[0015] Although not required, front cover panel 104 may have a
larger surface area than cover portions 102 and 106. Additionally,
forth cover portion 108 may have edges that are angled and extend
upwardly toward its central portion for connecting to first cover
portion 104. Such connection may be by any known method, such as
adhesive gluing, stapling, heat sealing, hot melt, and the
like.
[0016] Container top section 100 (shown in FIGS. 2 and 3) is formed
from cover portions 102, 104, 106, and 108. Container bottom
section 110 is formed from bottom portions 112, 114, 116, and 118.
Container cover portions and container bottom portions can also be
referred to as flaps.
[0017] As depicted in FIG. 1, inner wall portions 42, 22, and 52
have corresponding first portions 42a, 22a, and 52a, respectively,
and second portions, 42b, 22b, and 52b, opposite thereof,
respectively. Upon folding of the blank 10, first portions, 42a,
22a, and 52a, respectively, contact and are securely attached to
the inner surfaces of first side wall panel 40, front wall panel 20
and second side wall panel 50, respectively. Consequently, second
portions, 42b, 22b, and 52b form the interior upper portion 65 of
container 12, as shown in FIG. 3. Recesses or slot openings 43 and
45 are provided at the lower portion of crease fold lines 148 and
128 to provide flexibility to inner wall portions 22, 42, and 52
when attached to the inner surfaces of first side wall panel 40,
front wall panel 20, and second side wall panel 50, respectively.
In one embodiment, inner wall portions 22, 42 and 52 are secured to
panels 20, 40, and 50, respectively, by any means of attachment,
including, but not limited to, adhesive gluing, stapling, heat
sealing, hot melt, and the like.
[0018] Attached to first inner wall portion 22 is locking device 80
having first and second locking members 82 and 84, respectively,
and lines of weakness 84d, 86, and 88. First locking member 82 may
have reinforcing portion 90a that may be substantially the same
shape as grasping member 90. In FIGS. 1-3, reinforcing portion 90a
and grasping member 90 are represented as ovoid in configuration
but may have other shapes or configurations as well. For example,
grasping member 90 may be circular, straight, or sigmoidal-shaped,
and the like. Additionally, grasping member 90 may be a cut-out
area, that is, material is removed in certain shapes such as
ovoids, circles, square, and the like. Reinforcing portion 90a may
be the same general shape as grasping member 90 and may be slightly
smaller than grasping member 90. Upon attachment to the inner
surface of front wall panel 20, reinforcing portion 90a overlays
grasping member 90 and reinforces the grasping member when the user
initially opens cover 100 (see FIG. 3).
[0019] In an embodiment, first and second locking members 82 and
84, respectively, are located centrally, but any placement may be
used as well. Second locking member 84 includes crease score line
84a, upper edge 85 and sides 84b and 84c. Upper edge 85, which can
be straight, sigmoidal-shaped, and the like, is affixed to first
locking member 82 prior to initial container opening by line of
weakness 84d. While it is preferred that second locking member 84
be integral with first inner wall portion 22, crease score line 84a
may optionally include at least one partial cut on the outer edges.
Spaces 87 and 89 represent area wherein material has been removed
from first locking member 82 and sides 84b and 84c. In a one
embodiment, upon initial opening of the container, second locking
member 84 articulates along crease score line 84a. Upon closing
cover 100, second locking member 84 engages with first locking
member 82, which is attached to front wall panel 20, resulting in
an audible sound, e.g., a click or a snap.
[0020] In an embodiment, folding of the blank into a container is
made by running integral blank 10 print surface 15 down with 102,
104, 106 and 108 leading into the machine. Inner wall portion 52
and inner wall portion 22 are plowed inwards to inner wall portion
42 and back panel 30 along crease fold line 148. Locking device 80
along with locking member 84 are folded together onto inner wall
portion 22 along lines of weakness 86, 84a and 88. Adhesive, e.g.,
hot melt or cold adhesive, is applied to inner wall portion inner
wall portion 22 such that the lines, dots, or spots of adhesive do
not interfere with line of weakness 70. Simultaneously, adhesive
spots are applied to the non-printed side 17 of locking device 80.
The integral blank 10 is then plowed inwards along crease line 58.
Adhesive is then applied to print surface 15 of inner wall portion
42 just below the line of weakness 70. Adhesive is also applied to
manufactures joint 41. First side wall panel 40 is folded inwards
along crease line 48 to complete folding the container.
[0021] As previously mentioned, container top section 100 (shown in
FIGS. 2 and 3) is formed from cover portions 102, 104, 106, and 108
and container bottom section 110 is formed from bottom portions
112, 114, 116, and 118. In a one embodiment, upon folding, portions
102 and 106 are first articulated inwardly with fourth portion 108
being articulated next. Adhesive, or other attachment means, is
placed on the print surface 15 of cover portions 102, 106, and 108.
First cover portion 104 is articulated inwardly such that first
cover portion 104 is secured to cover portions 102, 106, and 108.
Cover portions 102 and 106 are initially articulated toward the
inner portion of container along crease score lines 44 and 54,
respectively. Fourth cover portion 108 and first cover portion 104
are articulated inwardly along crease score lines 24 and 34,
respectively. In the one embodiment, outer surface of fourth cover
portion 108 is then affixed to inner surface of cover portions 102,
104, and 106. Container bottom section 110 (seen in FIGS. 2 and 3)
is formed from bottom portions 112, 114, 116, and 118. Bottom
portions 112 and 116 are articulated inwardly along crease score
lines 46 and 56, respectively. In one embodiment, side portions 112
and 116 have a smaller surface area than bottom portions 114 and
118 and outer portion of fourth bottom portion 118 is secured to
the inner surface of front bottom portion 114.
[0022] FIG. 2 shows container 12 fully assembled and unopened.
Except for opening area 94, container top section 100 forms a
smooth, continuous surface with container bottom section 110. Upon
the initial opening of container by lifting top section 100 and
separating from container bottom section 110, a slight recess is
formed between wall panels 40, 20, and 50 with second inner wall
portions 42b, 22b, and 52b (recess shown in FIG. 3).
[0023] Container 12 has two continuous lines of weakness 60 and 70.
As seen in FIG. 1, line of weakness 60 extends from the
intersection of first side wall panel 40 and second cover panel 102
furthest away from front wall panel 20 across crease line 48 and
ending at opening area 94, which is formed about grasping member
90. Likewise, line of weakness 70 extends from the intersection of
second side wall panel 50 and third cover portion 106 furthest away
from front wall panel 20 across crease line 28 and ending at
opening area 94 formed about grasping member 90. While lines of
weakness 60 and 70 may be a straight, sigmoid or otherwise shaped,
in one embodiment, the lines of weakness 60 and 70 are curved.
[0024] In addition, lines of weakness 60 and 70 may be
perforations, slits, or alternating from slits to perforations, or
vice versa, or they may be glue spots corresponding with half-cuts
between the inner wall and outer cover. As seen in FIGS. 1, 2, and
4, line of weakness 70 alternates from slit portion 72 to
perforation portion 73 to slit portion 74 to perforation 75 and to
slit portion 76. Similarly, FIG. 1 shows line of weakness 60
alternating from slit portion 62 to perforation portion 63 to slit
portion 64 to perforation 65, and to slit portion 66. While lines
of weakness 60 and 70 have symmetrical alternation of perforations
and slits as compared to each other, such symmetry is not
required.
[0025] Nonetheless, in one embodiment, lines of weakness 60 and 70
have substantially constant resistances to separation along their
length. For example, if the continuous line of weakness 60 is a
scored line, then it is of constant depth and density.
Alternatively, if the continuous line of weakness 60 is a
perforated line, the dimensions of the perforation components and
the land components residing between adjacent perforation
components may or may not be constant. This can be seen more
readily in FIG. 4. Properties of the continuous lines of weakness
60 and 70 may vary slightly in the corners of the container to
impart strength properties and facilitate opening by the
consumer.
[0026] Continuous lines of weakness 60 and 70 can be made using any
known mechanical means, such as scoring or perforating; chemical
means, such as chemical etching; physical means, such as a laser;
or combinations thereof. Each continuous line of weakness 60 and 70
can be a single line, or alternatively a series of lines, such as
those that make up a tear strip configuration.
[0027] FIG. 4 is an enlarged view of area 200 of FIG. 2,
illustrating one embodiment of the continuous line of weakness 70
having perforation components 96 and land components 98. While only
continuous line of weakness 70 is shown in this view, it is
understood that continuous line of weakness 60 may be equivalent to
continuous line of weakness 70.
[0028] The dimensions of perforation component 96 and land
component 98 are preferably adjusted to the material selected in
order to ensure protection of the articles prior to initially
opening the container top section 100, while also allowing easy and
clean opening of the container. In one embodiment, perforation
component 96 represents an elongated separation that extends along
line of weakness 70 between land component 98. A plurality of
perforation components 96 extend along the continuous line of
weakness 70 are preferably about 1.5 to about 25 millimeters in
length, more preferably about 3 to about 4 millimeters in length. A
plurality of land components 98, preferably adjacent to at least
one perforation component 96, along the continuous line of weakness
70 are preferably from about 1 to about 4 millimeters in length.
Smaller lands often result in failure during container folding and
filling. Slit portions 72, 74 and 76 are preferably about from
about 10 mm to about 20 mm respectively. Longer slit portions are
preferred over shorter slit portions to minimize the force to
initially open the container. Combinations of perforation, land,
and slit areas will vary for containers of varying sizes and
materials. While not required, it is nonetheless preferred that a
slit portion is located in line of weakness 70 closed to top
section 100. While the preceding has described line of weakness 70,
it is understood that line of weakness 60 is similar. Breaking or
severing continuous lines of weakness 60 and 70 allows for opening
container 12 into two portions, cover 100 and bottom section 110
wherein cover 100 is hingedly attached to bottom section 110, hence
creating a flip-top container. By lifting cover 100, articles
contained in container 12 can be displayed, i.e, viewed, or
dispensed.
[0029] As seen in FIG. 3, when container 12 is assembled, first
locking member 82 is affixed to the top of the inner surface front
wall panel 20. Second locking member 84 is hingedly connected to
crease score line 84a of first wall portion 22 and articulates into
juxtaposition with second surface 22b. In FIG. 3, upper edge 85 of
second locking member 84 is disengaged from first locking member 82
by breaking of line of weakness 84d when cover section 100 is
lifted during initial container opening.
[0030] Grasping member 90 can be optionally employed to aid in
separating container top section 100 from container bottom section
110. Preferably, at least one grasping member 90 is employed such
that separation of top section 100 from bottom section 110 is
commenced from a central position upon lifting or grasping and
pulling grasping member 90. More preferably, grasping member 90 is
positioned substantially adjacent to lines of weakness 60 and 70.
Thus, grasping member 90 can be engaged and begin separating
container top section 100 from container bottom section 110 in a
single step. Grasping member 90 is defined by flexible line of
weakness 92. After initial opening of the container, flexible line
of weakness 92 may exhibit a slight resiliency that results in
grasping member 90 bowing outwards away for outer surface of front
wall panel 20. This bowing assists in facilitating opening of
container top section 100 from container bottom section 110.
Additionally, the bowing helps to prevent tearing about grasping
member 90.
[0031] Grasping member 90 should be of sufficient size and geometry
to readily receive at least the tip of one human finger.
Alternately, grasping member 90 may be removed. Various other
tools, such as a hook, could be inserted into grasping member 90
for separating container top section 100 from container bottom
section 110. Because the initial opening of the container requires
some force to tear or the lines of weakness, it may be desirable to
construct grasping member 90 from a heavy or rigid material to
prevent tearing upon the initial opening of the container. In one
embodiment, the first locking member 82, including tabular portion
90a, is adhered to the inner surface of front wall panel 20 to
provide thickness and support. In one embodiment, grasping member
90 is of ovoid shape, but may be any convex shape, concave shape,
or a combination thereof. It has been found that augmenting the
functionality of grasping member 90 may be accomplished by
implementing scores at either or both side ends of grasping member
90. Additionally, it is preferred for ease of use that opening area
94 separate grasping member 90 from outer front wall panel 20.
[0032] A representative, non-limiting list of materials useful in
constructing the container includes corrugated board (polymeric,
paper, and the like), paperboard, paper laminations, chipboard,
polymeric sheeting, foam board, and combinations thereof,
preferably the material is paperboard. Preferred paperboard is 16
pt or 250 g/m.sup.2 paperboard, solid bleach sulfate (SBS) or
recycled paperboard. Preferably, corrugated board comprises E-flute
corrugations.
[0033] Types of adhesive useful in the present invention include
hot melt or cold glue adhesives known in the industry and can be
applied by any known method, including but not limited to spraying,
rolling, or transfer methods.
[0034] The container of the present invention is useful for
shipping, storing, and displaying a wide range of articles,
