Definitions

  • Packages and methods for their manufacture are described herein and, in particular, packages having a plurality of individually sealed compartments, such as for confectionery products.
  • a gum package is a blister pack removably contained in a cardboard sleeve and including a first layer with thermoformed pockets for containing individual pellets and a second layer of film sealed to the first layer to cover the pockets. Pressing on the blister pack from the first layer side toward the second layer can cause the gum piece to rupture the second layer to form an opening through which the gum can be removed for consumption.
  • a disadvantage of such blister packs is the use of at least two different types of materials and increased number of steps for manufacture. This can undesirably increase complexity and cost of the manufacturing process.
  • the consumer before a user can press on the blister pack to remove a piece of gum, the consumer has to first remove the blister pack from its paperboard sleeve, adding an extra step for the consumer during the opening of the package.
  • the packages described herein include a plurality of individually sealed compartments, optionally formed from a single web of film.
  • Each of the compartments includes a line of weakness that can be ruptured by pushing on the film material and the gum piece toward the line of weakness.
  • the line of weakness advantageously provides the compartments with a hinged flap that opens in response to a force being applied by a consumer and remains attached to remainder of the film after opening.
  • the hinged flap may provide a tamper-evidence feature for the package and may be configured to make a snapping or other audible noise upon initial opening along the line of weakness.
  • the individually sealed compartments are separable from each other to permit a user to discard empty compartments after the food product is removed.
  • the used gum may be placed in the empty compartment to permit the user to discard both the used gum and the empty compartment.
  • a package comprises a plurality of individually sealed compartments.
  • Each of the compartments contains a food product in an interior defined between a back panel sealed to a front panel about the interior.
  • the front panel includes a flap detachable from adjacent portions of the front panel along a flap line of weakness to form an access opening configured to permit removal of the food product from the interior of the compartment.
  • the flap line of weakness may have first and second spaced ends intersecting a free edge portion of the package about which the flap is configured to pivot to form the access opening and the flap line of weakness extends from the first and second ends thereof toward an opposite edge portion of the package.

  • This deviation of the back panel 32 of the compartment 12 permits the force being applied by the consumer to be indirectly applied, via the interior surface 38 of the back panel 32 , to the food product 90 , and causes the food product 90 to exert a force in the direction toward the front panel 34 .
  • the force exerted by the food product 90 onto the interior surface 42 of the front panel 34 along the flap 26 causes the flap 26 to separate from adjacent portions of the front panel 34 along the flap line of weakness 24 .

It is to be appreciated that the tear in the flap line of weakness 24 may also initiate at either one or, simultaneously, at both of the portions 24 a and 24 b of the flap line of weakness 24 .
  • the flap line of weakness 24 may be configured such that the portion 24 c requires less tensile force to rupture than the portions 24 a and 24 b of the flap line of weakness 24 , thus ensuring that the flap line of weakness 24 preferentially ruptures initially at the portion 24 c.
  • the flap 26 provides a consumer with a visual indication of the degree of opening of the compartment 12 of the package 10 as shown in FIGS. 3 and 5 .

  • the package 1000 is not illustrated as having compartment lines of weakness 22 , 23 , and 25 similar to the package 10 , it will be appreciated that the package 1000 may be provided with compartment lines of weakness that permit any of the compartments 1012 of the package 1000 to be completely separated from the package 1000 individually and discarded.
  • the package 1000 is shown with an optional removable area 1099 and the package 10 is shown without such a removable area, it will be appreciated that the package 10 or any other package described herein may include a removable area similar to the removable area 1099 .
  • the removable area 1099 of the package 1000 may be separated from the package to expose an opening to permit the package 1000 to be placed on a hanging display rack at a convenience store or supermarket.
  • the package 1000 may be in a form of front and rear panels 1083 and 1085 sealed to each other along one or more edges by end seals 1089 being formed from a material selected to provide a detachable attachment of the front and rear panels 1083 and 1085 such that the package 1000 may be opened from the closed configuration of FIG. 25 to the extended configuration of FIG. 26 by movement of the front and rear panels 1083 and 1085 of the package 1000 away from each other.
  • the package may also include a closure flap 1095 non-detachably attached to a portion of the rear panel 1085 by a seal 1081 or an adhesive and including a line of weakness 1087 that permits portions of the closure flap 1095 to separate from each other along the line of weakness 1087 when the package 1000 is initially opened and moved from the position of FIG.
  • closure flap 1095 and the line of weakness 1087 thus provide a tamper-evidence feature for the package 1000 such that the partial detachment of the closure flap 1095 would visually indicate to a consumer that the package 1000 has been previously opened or tampered with.
  • the compartments 1012 of the package 1000 may be opened substantially the same way as the compartments 12 , 212 , and 412 of the packages 10 , 200 , and 400 in response to an application of force by a consumer to a panel of the package 1000 to force a flap 1026 of a compartment 1012 of the flexible package 1000 to separate from adjacent portions of the compartment 1012 along a flap line of weakness 1024 and move to an open position to provide the consumer with access to the food product 90 retained in the compartment 1012 .

  • the shape and orientation of the flap line of weakness 1024 may be selected from various alternatives that may be selected, for example, to facilitate the ease of the opening of the compartments 1012 of the package 1000 by the consumers, or to provide a visual indication of where the compartment 1012 may be opened, or just to provide a visually pleasing design.
  • FIGS. 31B-31E Some possible alternatives of the shapes and orientations of the flap lines of weakness 1024 of the compartment 1012 of the package 1000 are shown in FIGS. 31B-31E . In the embodiment shown in FIG.
  • the flap line of weakness 1024 includes first and second segments 1024 a and 1024 b each having end portions 1025 and 1027 that are hook shaped, which may restrict unintended propagation of a tear along the flap line of weakness 1024 beyond the endpoints 1025 and 1027 .
  • one of the segments 1024 b of the flap line of weakness 1024 having the hook-shaped portions 1025 b and 1027 b may be shorter than the other one of the segments 1024 a of the of the flap line of weakness 1024 having the hook-shaped portions 1025 a and 1027 a such that the flap line of weakness 1024 may preferentially tear initially at the segment 1024 a rather than the segment 1024 b when the consumer applies an opening force to the compartment 1012 .
  • the package 1000 may be similar to the package 400 of FIGS. 19 and 20 in that the compartments 1012 of the package 1000 include thermoformed pockets 1080 .
  • compartments 1012 of the package 1000 may alternatively be formed without the thermoformed pockets 1080 similarly to the compartments 12 of the package 10 .
