Definitions

  • the present disclosure generally relates to product packaging. More specifically, the present disclosure relates to child-resistant packaging for storing regulated products therein.
  • Regulated products are generally required to be sold and stored in child-resistant packaging so that children cannot access the contents therein.
  • pre-rolls pre-rolled joints
  • Pre-rolls are convenient in that a user does not need to roll their own joint in order to smoke cannabis.
  • Pre-rolls are generally sold individually or in groups of two to ten. Individually sold pre-rolls are typically packaged in plastic tubes having a child-resistant lid, similar to those used for prescription pill bottles. Groups of pre-rolls, however, are typically sold in packaging similar to that used for cigarettes - i.e. a pack in which a plurality of pre-rolls may be stored.
  • the child-resistant features used for the pre-roll packages are considerably different from those used for the individually sold pre-rolls.
  • the pre-roll packages may be outfitted with child-resistant features that are single-use in that, once the packaging is opened, the child-resistant feature will no longer function (e.g. the package may be perforated such that the top may be torn off).
  • some pre-roll packages include a plastic insert having tabs that extend out of apertures formed in the package that may be depressed in order to allow the plastic insert to be removed.
  • such configurations complicate manufacturing, as multiple types of materials are required to produce a single package. Further, after multiple uses, the plastic insert may become permanently deformed, making it difficult even for adults to remove the insert from the package.
  • the present disclosure recognizes that there are problems with existing child-resistant packaging for regulated products, including those for containing cannabis products.
  • the present disclosure relates to a child-resistant package for a regulated product, the package comprising: a housing having an open end, a plurality of release tabs formed in a wall thereof, and a locking edge defined on an inside surface thereof; and an insert for containing the regulated product slidably received through the open end of the housing, the insert having: an openable end for accessing the regulated product, the openable end openable when the insert is at least partially removed from the housing; and a locking tab positioned on an outside surface of the insert having a plurality of ends that are each aligned with one of the plurality of release tabs, the locking tab biased such that each of the plurality of ends contact the locking edge when sliding the insert out of the housing without depressing the plurality of release tabs.
  • the present disclosure relates to use of the child-resistant package described herein for storing a regulated product.
  • the regulated product may comprise one or more cannabis products.
  • the present disclosure generally relates to child-resistant packaging and, in particular, to child-resistant packaging for a regulated product.
  • the child-resistant packages of the present disclosure afford a number of advantages over conventional packages.
  • the child-resistant packages may be used multiple times without affecting their usability.
  • some conventional child-resistant packages such as those having a plastic insert defining deformable tabs, may become permanently deformed after multiple uses, which may make it more difficult to access the regulated product contained therein or, in some cases, may make it so that a child can easily slide the insert out of the package.
  • the child-resistant packages of the present disclosure may be manufactured with relative ease.
  • the child-resistant packages may be formed of a simple two-piece construction.
  • each piece of the two-piece construction may advantageously be formed of the same material.
  • Such configurations significantly simplify the manufacturing process, which may greatly reduce the costs associated with the production of the child-resistant packages.
  • the manufacturing processes may be readily upscaled to industrially relevant levels, meaning that the child-resistant packages of the present disclosure are not limited to smaller-scale applications (e.g. craft cannabis products).
  • conventional child-resistant packaging for regulated products may comprise multiple pieces that are each formed of a different material, which complicates the manufacturing process significantly.
  • child-resistant packages of the present disclosure may be biodegradable.
  • conventional child-resistant packaging may include one or more plastic components.
  • product packaging for regulated products such as cannabis products is often not disposed of properly.
  • a package that is biodegradable may be particularly advantageous, as, in the event that it is not properly disposed of, it will at least degrade over time without having any potentially environmentally harmful components such as plastics, metals, and the like remain.
  • the present disclosure relates to a child-resistant package for a regulated product, the package comprising: a housing having an open end, a plurality of release tabs formed in a wall thereof, and a locking edge defined on an inside surface thereof; and an insert for containing the regulated product slidably received through the open end of the housing, the insert having: an openable end for accessing the regulated product, the openable end openable when the insert is at least partially removed from the housing; and a locking tab positioned on an outside surface of the insert having a plurality of ends that are each aligned with one of the plurality of release tabs, the locking tab biased such that each of the plurality of ends contact the locking edge when sliding the insert out of the housing without depressing the plurality of release tabs.
  • regulated product refers to a consumer product that is regulated in some capacity by a government agency.
  • regulated products include tobacco products, cannabis products, pharmaceuticals, and the like.
  • child-resistant package or “child-resistant packaging” means a packaging product that is configured to be difficult for children to open but readily openable by adults to reduce the likelihood that children may access the contents contained therein.
  • housing refers to a component of the child-resistant package that slidably receives the insert therein.
  • the housing has a body with at least one open end, through which the insert is slidably received.
  • the body of the housing may be any suitable shape such as, for example, a rectangular prism. In such configurations, the body may have a front wall and a back wall that are larger than the sidewalls thereof.
  • the housing also has a locking edge defined on an inside surface of its body.
  • locking edge refers to a feature of the housing used to prevent the insert from being removed once received therein.
  • the locking edge extends from the inside surface of the housing such that the locking tab of the insert can contact it when a user attempts to remove the insert from the housing, thereby stopping the insert from moving any further.
  • the locking edge may be formed using a number of configurations.
  • the housing also has a plurality of release tabs formed in a wall thereof.
  • release tabs refer to portions of the body of the housing that may be depressed to, in turn, depress the ends of a locking tab of the insert to thereby allow the insert to be removed from the housing (e.g. by pulling the insert out of the housing).
  • the release tabs may be formed by cutting the tabs into the body of the housing, for example.
  • the release tabs may be formed in the wall of the housing by marking them thereon.
  • the release tabs are aligned with the ends of the locking tab of the insert such that depressing the release tabs depresses the ends of the locking tab, as will be described below.
  • the release tabs are also positioned close enough to the locking edge that the locking tab cannot return to its initial position before passing the locking edge when a user attempts to remove the insert from the housing while depressing the release tabs.
  • insert refers to a component of the child-resistant package that is configured to contain therein the regulated product and to be slidably received within the housing.
  • the insert has a body with an openable end for accessing the regulated product contained therein when the insert is at least partially removed from the housing. That is, the openable end is not openable when it is positioned within the housing.
  • the body of the insert is generally the same shape as the housing so that it may be readily received therein and so that the locking tab of the insert may be easily aligned with the release tabs of the housing.
  • the insert also has a locking tab positioned on an outside surface thereof.
  • the locking tab has a plurality of ends and is biased such that its ends will abut the locking edge when attempting to pull the insert out of the housing without depressing the release tabs, thus preventing the insert from being removed.
  • the ends of the locking tab are aligned with the release tabs of the housing such that depressing the release tabs also depresses the ends of the locking tab. Because of the bias, after the locking tab has been moved away from the release tabs (e.g. while removing the insert from the housing) or after the release tabs are no longer depressed, it will return to its initial position. Further, as will be discussed below, the locking tab is generally arranged such that is does not prevent the insert from being slid into the housing.
  • depressing the release tabs of the housing depresses the ends of the locking tab such that they do not contact the locking edge when pulling the insert out of the housing, thereby allowing the insert to be removed.
  • the insert may then be slid back into the housing, at which point the locking tab will return to its initial position to render the package child-resistant.
  • the child-resistant package 10 comprises a housing 20 and an insert 30 slidably received within the housing 20.
  • the housing 20 has an open end though which the insert 30 is slidably received.
  • the open end of the housing 20 may have cut-outs 29 formed therein to facilitate the removal of the insert 30 from the housing 20 by exposing a portion of the insert 30 for a user to grip while pulling the insert 30 out of the housing 20.
  • the cut-outs 29 may be formed in the sidewalls of the housing 20, as shown in FIG. 1 .
  • the cut-outs 29 may be formed in the front and back walls of the housing 20.
  • the cut-outs 29 may be formed in a combination of front, back, or sidewalls of the housing 20.
  • the cut-outs 29 are curvilinear, but other shapes are possible and are contemplated.
  • the cut-outs 29 may be generally square-shaped.
  • the housing 20 also has a plurality of release tabs 22 formed in a wall thereof.
  • the plurality of release tabs 22 comprises two tabs; however, other numbers of release tabs 22 may be used if so desired.
  • the housing 20 may comprise one or more additional release tabs (not shown) in another side thereof, such as a sidewall.
  • the plurality of release tabs 22 may be formed by cutting them into the housing 20, as shown in FIG. 2 . In such embodiments, the cut portion of the housing 20 that defines the release tabs 22 is depressible into the housing 20, while the uncut portions provide a slight bias away from the insert 30 so that the release tabs do not remain depressed after use.
  • the release tabs 22 may otherwise be marked on the housing 20 but not cut into the housing 20. The marked release tabs 22 indicate the portions of the housing 20 for a user to depress.
  • the release tabs 22 may be shaped in order to facilitate their pressing by the fingers of a user. That is, the release tabs 22 may be dimensioned large enough so that they are easy to depress by adult fingers. For example, in some embodiments, the release tabs 22 may have a width of about 7.5 mm to about 15 mm. In some embodiments, the release tabs 22 have a length of about 5.0 mm to about 10 mm. Further, it is noted that, while the release tabs 22 are a generally rounded shape in the illustrated embodiment, other shapes are possible and are contemplated. In some embodiments, the release tabs 22 may be generally squared.
  • the release tabs 22 are generally horizontally aligned. However, other arrangements are possible and are contemplated. For example, in some embodiments, the release tabs 22 may be aligned generally vertically, diagonally, etc.
  • the housing 20 also comprises a locking edge 24, as shown in FIG. 3 .
  • the locking edge 24 provides a surface for a locking tab 32 of the insert 30 (see FIG. 4 ) to abut in order to prevent the insert 30 from being removed from the housing 20.
  • the locking edge 24 may be a piece of material adhered to the inside surface of the housing 20.
  • the locking edge 24 may be formed by cutting a section of housing 20 and bending the section downwardly into the housing 20 such that it may abut the locking tab 32 of the insert 30 when attempting to slide the insert out of the housing 20.
  • the locking edge 24 is defined by an inner panel 26.
  • the inner panel 26 is a separate piece of material adhered to the housing 20.
  • the inner panel 26 is a portion of the housing 20 folded and adhered to an inside surface thereof.
  • the inner panel 26 has a recess 28 formed therein that defines an additional locking edge 24a.
  • the additional locking edge 24a may prevent the insert 30 from being completely removable from the housing 20.
  • the locking tab 32 in operation, when the insert 30 is being slid out of the housing 20, the locking tab 32 will return to its initial position as it moves away from the depressed release tabs 22, at which point the locking tab 32 is capable of contacting the additional locking edge 24a. As shown in FIG. 3 , the locking edge 24a is positioned above the locking edge 24. Thus, after the locking tab 32 returns to its initial position, the locking tab 32 will then abut the additional locking edge 24a, thereby preventing the insert 30 from being further removed from the housing 20.
  • the locking tab 32 may be slid back out of the recess 28 without abutting another edge thereof, thereby allowing the insert 30 to be easily pushed back into the housing 20.
  • Such embodiments may be beneficial, as a user is prevented from completely removing and subsequently losing the insert 30, which may affect the child-resistance of the package 10.
  • the recess 28 has a generally rectangular shape, any shape is possible so long as the recess 28 still defines the additional locking edge 24a.
  • the locking edge 24 and, if present, the locking edge 24a have a height that allows the locking tab 32 to contact them when not depressed by the release tabs 22.
  • the locking edges 24, 24a may have about a height of about 0.1 mm to about 1 mm.
  • the illustrated embodiment shows the locking edges 24, 24a extending across a majority of width of the housing 20, such a configuration is not required. Rather, the locking edges 24, 24a may be functional as long as they extend along enough of the width of the housing 20 that they are contactable by each end of the locking tab 32.
  • the locking edge 24 is positioned close enough to the release tabs 22 that the locking tab 32 cannot return to its initial position before passing thereover when a user attempts to remove the insert 30 while depressing the release tabs 22. In some embodiments, the locking edge 24 is positioned about 0.1 mm to about 3 mm away from the release tabs 22.
  • the insert 30 has an openable end 36 for accessing the regulated product contained therein.
  • the openable end 36 is only openable when the insert 30 is at least partially removed from the housing 20, as shown in FIG. 5 .
  • the openable end 36 may be hingedly openable, as in the illustrated embodiment, in which the openable end 36 hinges away from the body of the insert 30 to allow access to the contents thereof.
  • the openable end 36 if the insert 30 is not at least partially removed from the housing 20, the openable end 36 cannot open, as a portion of the openable end 36 abuts an inside surface of the housing 20, thereby preventing it from hinging open.
  • the insert 30 also has the locking tab 32 positioned on an outside surface thereof.
  • the locking tab 32 if not depressed via the release tabs 22, prevents the insert 30 from being slidably removed from the housing 20.
  • the locking tab 32 comprises a plurality of ends 34 and is biased such that, when not depressed by the release tabs 22, the plurality of ends 34 will contact the locking edge 24 when attempting to slide the insert 30 out of the housing 20, thereby preventing the insert 30 from being removed from the housing 20.
  • the biasing of the locking tab 32 may result in the locking tab 32 being angled towards the top of the insert 30 such that it forms an acute angle with the wall of the insert 30.
  • Such configurations may be beneficial, as the insert 30 may be easily slid back into the housing 20 without the locking tab 32 abutting features of the housing 20 such as the recess 28 to prevent the receiving of the insert 30.
  • the number of ends 34 of the locking tab 32 may correspond to the number of release tabs 22.
  • each release tab 22 depresses an end 34 so that the locking tab 32 may pass below the locking edge 24 when the insert is being slid out of the housing 20.
  • one release tab 22 may be configured to depress more than one end 34 of the locking tab 32.
  • the locking tab 32 is formed of a separate piece of material that is adhered to the insert 30.
  • the locking tab 32 is formed from the same piece of material as the insert 30 (e.g. cut into the insert 30 in the same manner as the release tabs 22 and the housing 20 described above) and folded upwards towards the top of the insert 30 so that the locking tab 32 is biased to abut the locking edge 24 when the insert 30 is being removed from the housing 20.
  • Such a configuration is used in the embodiment illustrated in FIG. 4 and beneficially allows the insert 30 to be formed of only a single piece of material.
  • the ends 34 of the locking tab 32 may be spaced away from each other. Such configurations may be beneficial, as depressing only one of the ends 34 will not result in the entire locking tab 32 being depressed, which may increase the child-resistance of the package 10. Further, as shown in the embodiment illustrated in FIG. 4 , the ends 34 of the locking tab 32 may be generally square with a curvilinear edge bridging the two ends 34. However, the ends 34 may be any other suitable shape, so long as they have sufficient surface area to be depressed by the release tabs 22.
  • the insert 30 may define two or more internal compartments 38 for containing multiple regulated products separately therein, as shown in FIG. 5 .
  • the compartments 38 may be defined by a separate piece of material positioned in the insert 30.
  • the compartments 38 may be defined by a portion of the insert 30 folded into itself. Such configurations may be beneficial, as the compartments 38 and insert 30 may be formed using only a single piece of material.
  • FIG. 4 has two internal compartments 38 defined within the insert 30, there may be 3, 4, 5, 6, or more internal compartments 38 defined within the insert 30, if so desired.
  • each of the housing 20 and the insert 30 may each be independently formed of a paperboard material. In some embodiments, each of the housing 20 and the insert 30 may be coated with a cellophane. Thus, as previously described herein, the housing 20 and the insert 30, and, as a result, the package 10, may be biodegradable.
  • the housing 20, the insert 30, or a combination thereof may be reinforced with a reinforcement material such as a foil, a plastic, or the like.
  • the reinforcement material may be a biodegradable plastic.
  • Suitable biodegradable plastics include polylactic acids (PLAs), polyhydroxyalkanoates (PHAs), complexed starches, and the like.
  • the housing 20 and the insert 30 may be formed of a single piece of material such that the resulting package 10 has a simple two-piece construction.
  • each of the housing 20 and the insert 30 may be formed of a single piece of paperboard material that has been folded to form the components thereof.
  • FIG. 6 and FIG. 7 show, respectively, examples of non-constructed paperboard blanks of the housing 20 and the insert 30.
  • blades refer to pieces of material that have been cut such that they can be subsequently folded into a selected component. The blanks may be cut into appropriate shapes using any suitable industrial equipment, such as a die. In FIG. 6 and FIG.
  • the blanks may be folded along the dashed lines to form the housing 20 and the insert 30. Folded portions may be adjoined using any suitable industrial adhesive such as a hot-melt glue or a cold glue. It is noted that features such as the release tabs 22 and the locking tab 32 that may be cut into the housing 20 or insert 30 may be marked on the blanks and cut into the respective components after folding or, alternatively, may be cut into the blanks prior to folding.
  • FIG. 7 also illustrates an optional inner frame 40.
  • the inner frame 40 may be a separate piece that is adherable into the insert 30 to provide additional structural support thereto.
  • the inner frame 40 may also define one or more of the internal compartments 38.
  • the inner frame 40 may comprise one or more tabs 42 for maintaining the openable end 36 in a closed position after pulling the insert 30 out of the housing 20.
  • the one or more tabs 42 may be formed in the inner frame 40 along portions that are to be folded to define the edges thereof, as shown in FIG. 7 . After folding, the one or more tabs 42 will extend out beyond the now-defined edge such that they capable of contacting an inner portion of the openable end 36 when in a closed position to thereby maintain the openable end 36 in the closed position via a friction fit.
  • FIG. 6 and FIG. 7 each show only one example of blanks for forming the housing 20 and insert 30, other configurations of blanks are possible and are contemplated.
