The present invention relates to containers and methods of use thereof. More particularly, the invention relates to containers that provide dispensing or dosing of the stored product.
Various types of containers for dispensing solid objects, particularly solid products intended for human consumption, are known in the art. Such containers are often characterized by a hand-held size that can be easily stored and transported. Exemplary consumable products that are often packaged in such containers include pharmaceutical compositions, oral tobacco products, snacks, mints, gums, breath strips, candy, and the like.
Certain consumable products, such as pharmaceutical products, require containers having a certain level of child resistance. Traditionally, pills have been packaged in a bottle having a cap that can only be removed by applying downward pressure while twisting the cap. However, this type of child resistance has certain disadvantages. For example, if a child does manage to open the bottle, immediate access is provided to the entire contents of the bottle. Further, if an adult user fails to place the cap in the properly secured position, there is no secondary mechanism for preventing access by a child.
Exemplary containers that provide a locking mechanism for enhancing child-resistance of a container can be found, for example, in U.S. Pat. No. 6,863,175 to Gelardi; U.S. Pat. No. 6,913,149 to Gelardi et al.; U.S. Pat. No. 6,976,576 to Intini; and U.S. Pat. No. 7,216,776 to Gelardi; U.S. Pat. Publication Nos. 2009/0223989 to Gelardi and 2009/0266837 to Gelardi et al.; and U.S. patent application Ser. Nos. 12/412,809 to Bailey et al.; 12/425,180 to Bailey et al.; and 12/685,819 to Bailey et al., which are incorporated herein by reference in their entirety.
In addition to child resistance, another desirable feature for certain containers is the ability to dispense a metered amount of a product. In other words, it can be highly desirable for the container to control dispensing such that only a defined number of stored product units, such as only a single unit, is dispensed each time the container is opened. Metered distribution of a product can be advantageous as a further level of child resistance as it prevents unrestricted access to the entire contents of the container, and as a means to improve sanitation because such a container negates the need to touch numerous units within the container in order to obtain a single desired unit.
Further, another desirable feature for certain containers is the protection of the product from environmental effects, particularly those effects that may degrade the product stored in the container. For example, in humid environments, moisture may invade the storage space housing the product, thereby damaging the product or otherwise rendering the product unusable.
There remains a need in the art for a container for storing and dispensing a product capable of combining various advantageous features, such as child resistance, moisture protection, metered dispensing, and convenient size.
The present invention provides a container that, in certain embodiments, combines child-resistance with moisture protection, and which can be provided in a convenient handheld size. The type and form of the product to be stored and dispensed can vary.
In one embodiment, the container of the invention comprises an outer casing body having a cavity therein. The outer casing body includes first and second portions cooperatively configured such that the outer casing body is capable of moving between a closed and locked position and a dispensing position. A dispensing tray is disposed within the cavity of the outer casing body and has an outer peripheral portion. The dispensing tray includes an internal storage compartment adapted for storage of a plurality of units of a product to be dispensed. The dispensing tray has a cover portion defining at least one dispensing aperture through which a stored unit of product is accessible when the outer casing body is in the dispensing position. A sealing member is operably engaged with one of the outer casing body and the dispensing tray. The sealing member is configured to interact with the other of the outer casing body and the dispensing tray to form a seal about the outer peripheral portion of the dispensing tray when the outer casing body is in the closed and locked position. A locking mechanism operably engaged with the outer casing body is configured to releasably lock the outer casing body in the closed and locked position.
In another aspect, the invention provides a method of dispensing at least one unit of a product from a container, the method comprising the steps of:
providing a container in a closed and locked position, the container comprising:
releasing the locking mechanism so as to effectuate separation of the first and second portions of the outer casing body to the dispensing position; and
removing at least one unit of product from the internal storage compartment.
In yet another aspect, the invention provides a method of sealing a product in a container, the method comprising the steps of:
providing a container in a dispensing position, the container comprising:
engaging the locking mechanism such that the first and second portions of the outer casing body enclose the dispensing tray and the sealing member sealingly engages the other of the outer casing body and the dispensing tray.
These and other features, aspects, and advantages of the invention will be apparent from a reading of the following detailed description together with the accompanying drawings, which are briefly described below.
Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present invention now will be described more fully hereinafter with reference to certain preferred embodiments. These embodiments 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. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms “a”, “an”, “the”, include plural referents unless the context clearly dictates otherwise.
The container embodiments described in the present application can be used to store and dispense any solid products, but are particularly well-suited for products designed for oral consumption. Exemplary consumable products include pharmaceutical products such as pills and tablets, cigarettes and other smoking products, smokeless tobacco products, candies, mints, gums and other confectionary products, snacks, and the like.
Exemplary tobacco products include pelletized tobacco products (e.g., compressed or molded pellets produced from powdered or processed tobacco, such as those formed into the general shape of a coin, cylinder, bean, pellet, sphere, orb, strip, obloid, cube, bead, or the like), extruded or cast pieces of tobacco (e.g., as strips, films or sheets, including multilayered films formed into a desired shape), products incorporating tobacco carried by a solid substrate (e.g., where substrate materials range from edible grains to inedible cellulosic sticks), extruded or formed tobacco-containing rods or sticks, tobacco-containing capsule-like materials having an outer shell region and an inner core region, straw-like (e.g., hollow formed) tobacco-containing shapes, sachets or packets containing tobacco (e.g., snus-like products), pieces of tobacco-containing gum, and the like.
Exemplary smokeless tobacco compositions that can be packaged in the containers of the invention are set forth in, for example, U.S. Pat. No. 1,376,586 to Schwartz; U.S. Pat.

Examples of tobacco-containing gum are set forth in U.S. Pat. No. 4,624,269 to Story et al.; U.S. Pat. No. 4,975,270 to Kehoe; and U.S. Pat. No. 4,802,498 to Ogren. Various manners or methods for packaging smokeless tobacco products are set forth in US 2004/0217024 and US 2006/0118589 to Arnarp et al.; WO 2005/016036 to Bjorkholm; WO 2006/034450 to Budd; WO 2007/017761 to Kutsch et al.; and WO 2007/067953 to Sheveley et al. All of the above-cited references are incorporated by reference herein in their entirety.
Smokeless tobacco compositions utilized as the product contained in the containers of the invention will often include such ingredients as tobacco (typically in particulate form), sweeteners, binders, colorants, pH adjusters, fillers, flavoring agents, disintegration aids, antioxidants, oral care additives, and preservatives. See, for example, US 2007/0186941 to Holton et al., which is incorporated by reference herein in its entirety.
The size and shape of the product to be stored and dispensed can vary. Exemplary product shapes include pills, tablets, spheres, orbs, strips, films, sheets, coins, cubes, beads, ovoids, obloids, cylinders, bean-shaped, sticks, or rods. Cross-sectional shape of the products can vary, and exemplary cross-sectional shapes include circles, squares, ovals, rectangles, and the like. The dimensions of the product will often vary depending on its shape. In one embodiment, the product is pellet or bean-shaped, and has a length and width in the range of about 3 mm to about 20 mm, more typically about 5 to about 12 mm. In another embodiment, the product is rod-shaped with a length in the range of about 50 to about 100 mm (more typically about 60 to about 80 mm) and a diameter of about 2 mm to about 8 mm (more typically about 3 mm to about 6 mm).
In one embodiment, the product is in the form of a flattened sheet or film. The sheet-like or film material typically has a shape that can be described as generally rectangular (optionally with rounded corners or edges), oval, triangular, or diamond-shaped. A generally rectangular sheet or film product will typically have a length in the range of about 20 to about 40 mm, more often about 25 to about 35 mm, and in some cases, between about 30 and about 35 mm (e.g., about 33 mm). The width of a generally rectangular sheet or film product will typically range from about 12 to about 28 mm, more often about 15 to about 25 mm, and in some cases, between about 18 and about 22 mm (e.g., about 20 mm). The thickness of the sheet or film product is typically within the range of about 0.05 to about 0.75 mm, more often about 0.1 to about 0.5 mm, and in some cases, between about 0.15 and about 0.25 mm. Sheet-shaped products are typically arranged in a stacked configuration within the storage compartment of the containers of the invention.
When the product is a smokeless tobacco composition, the sheet or film product can take a variety of forms, including films or sheets formed using tobacco reconstitution techniques known in the art. Alternatively, the sheet or film product can be in the form of so-called “edible films” or “orally dissolvable strips” that incorporate a tobacco component. Exemplary sheet or film materials are set forth in U.S. Pat. No. 5,587,172 to Cherukuri et al.; U.S. Pat. No. 5,733,577 to Myers et al.; U.S. Pat. No. 5,869,098 to Misra et al.; U.S. Pat. No. 5,871,781 to Myers et al.; U.S. Pat. No. 6,337,082 to Fuisz et al.; U.S. Pat. No. 6,596,298 to Leung et al.; U.S. Pat. No. 7,067,115 to Bess et al.; and U.S. Pat. No. 7,025,983 to Leung et al.; US 2004/0241242 to Fuisz et al.; US 2005/0244521 to Strickland et al.; US 2006/0039953 to Leung et al.; US 2006/0198873 to Chan et al.; US 2006/0204559 to Bess et al.; US 2007/0069416 to Yang et al.; US 2008/0029110 to Dube et al.; U.S. Ser. No. 11/781,641 to Mua et al. (2007); and U.S. Ser. No. 12/014,525 to Robinson et al. (2008), all of which are incorporated by reference herein in their entirety.
The shape of the outer surface of the containers of the invention can vary. Although the container embodiments illustrated in the drawings have certain contours, containers with other exterior surface designs could also be used. For example, the sides or edges of the containers of the invention could be flattened, rounded, or beveled, and the various surfaces or edges of the container exterior could be concave or convex. Further, the opposing sides, ends, or edges of the container can be parallel or non-parallel such that the container becomes narrower in one or more dimensions.
The dimensions of the containers described herein can vary without departing from the invention. However, in preferred embodiments, the containers of the invention can be described as having a size suitable for handheld manipulation and operation. Exemplary dimensions for such handheld embodiments include lengths in the range of about 25 mm to about 200 mm, more typically about 50 mm to about 150 mm, and most often about 80 mm to about 120 mm. Exemplary widths include the range of about 10 mm to about 100 mm, more typically about 20 mm to about 80 mm, and most often about 30 mm to about 60 mm. As used herein, length and width refer to the major dimensions of the container that define the major plane of the container. Exemplary depths for handheld container embodiments of the invention range from about 5 mm to about 50 mm, more typically about 8 mm to about 30 mm, and most often about 10 mm to about 20 mm.
The number of solid product units stored in the containers of the invention can also vary, depending on the size of the container and the size of the product units. Typically, the number of stored product units will vary from about 5 to about 100, more typically about 10 to about 50, and most often about 15 to about 30.
The material of construction of the container can also vary. Exemplary materials include metal, wood, and synthetic plastic materials. Polymeric materials that can be extruded and/or molded into desired shapes are typically utilized, such as polyethylene, polystyrene, polyamide, and the like.
In certain embodiments, the containers of the invention combine several advantageous features, such as child-resistance, moisture protection, and metered dispensing of a product. In particular, certain embodiments of the containers of the invention include a child-resistant locking mechanism that releasably locks a dispensing chamber of the container in a closed and locked position. The locking mechanism can be released and a product dispensed using a series of manipulations including, for example, depressing a locking button or flap and separating portions of the container to expose the product to be dispensed. The containers of the invention can provide moisture protection of the product by providing a sealing member for limiting moisture content within the container. The containers of the invention also provide, in certain embodiments, metered dispensing of the product by providing a dispensing pathway sized for passage of a single unit of the product so that only a single unit of product can enter a dispensing aperture at one time.
Certain preferred embodiments of the invention are described herein as referring to metered dispensing of a single unit of product, which can be, for example, a single consumable unit of a smokeless tobacco product, a single consumable unit of a confectionary or snack product, or a single dosage unit of a pharmaceutical product. However, the invention encompasses embodiments where the product is dispensed in greater amounts, such as a plurality of units. For example, the dispensing aperture and dispensing chamber described herein could be sized to provide space for more than one unit of product if desired.
In some embodiments, the outer casing body 100 may include a hinge portion 108 for hingedly coupling the first and second portions 104, 106 such that the outer casing body 100 can move between the closed and open positions. The hinge portion 108 may be integrally formed with the first and second portions 104, 106 such that the outer casing body is formed as a single unit. In other instances, the first and second portions 104, 106 may be discrete (separate) pieces that are hinged by a discrete hinge member (not shown). In another embodiment, the first and second portions 104, 106 may be discrete pieces that are not hinged, but still allow separation of the first and second portions 104, 106. That is, the first portion 104 may be entirely removable with respect to the second portion 106 so as to permit access to the cavity 102 defined thereby.
The outer casing body 100 may include a child resistance or locking mechanism, generally designated 500, to maintain the outer casing body 100 in a closed and locked position, as shown in
The container 10 further includes a dispensing tray 200 for storing a product to be dispensed. The dispensing tray 200 may be received within the cavity 102 of the outer casing body 100. In one embodiment, the dispensing tray 200 may be received within the second portion 106 of the outer casing body 100. The dispensing tray 200 may be permanently or temporarily coupled to the second portion 106. For example, the dispensing tray 200 may be securely coupled to second portion 106 via an interference fit or with an adhesive fastener, or otherwise by any appropriate fastening or coupling mechanism. In other instances, the dispensing tray 200 may be integrally formed with the outer casing body 100 as a single piece unit. In such instances, the dispensing tray 200 and the outer casing body 100 may not be separate and distinct pieces. Both the dispensing tray 200 and the outer casing body 100 can be constructed in multiple parts that are affixed together using any means known to the skilled artisan. In other instances, both the dispensing tray 200 and the outer casing body 100 could be formed as a single unitary structure. One or more open-ended slots 112 may be defined by the outer casing body 100 to facilitate removal of the dispensing tray 200 therefrom.
The dispensing tray 200 may include an internal storage compartment 202 for storage of a plurality of units 300 (
A cover plate or portion 250 may be provided for containing the units 300 within the internal storage compartment 202. In some instances, the cover portion 250 may be provided as a separate and discrete piece from the dispensing tray 200. The dispensing tray 200 may define a ledge 210, which, in some instances, may be substantially planar, for receiving the cover portion 250 in a recessed manner such that the dispensing tray 200 and the cover portion 250 form a substantially planar upper surface 212. The cover portion 250 may be secured to the dispensing tray 200 plate by any suitable mechanism, including, but not limited to, a press-fit, snap-fit, or interference fit. However, other methods for affixing these cover portion 250 and the dispensing tray 200 may be provided. In some instances, the dispensing tray may include a channel 220 configured to receive a lip portion 254 of the cover portion 250 (see
In some instances, the cover portion 250 may be opaque (
Embodiments of the present invention may also include a sealing member 400 for sealing the product within the container 10 and providing a moisture barrier to limit degradation of the product due to moisture or other environmental conditions. As shown in
In some instances, the sealing member 400 may be substantially configured as a ridge or rib-like structure, as particularly shown in
In other embodiments, the sealing member 400 may be provided about the peripheral portion 208 of the dispensing tray 200, as shown in
The outer casing body 100 shown in
The arm member 540 may be deflected inwardly toward the peripheral portion 208 of the dispensing tray 200 such that the arm member 540 may be received within the channel 542. The tab member 544 of the arm member 540 may extend through a slot 546 defined by the second portion 106 of the outer casing body 100. The tab member 544 is capable of sliding laterally within the slot 546 so as to release the locking mechanism 500 such that the container 10 can move between the locked and closed position and the dispensing position. That is, sliding the tab member 544 causes the arm member 540 to move laterally within the channel 542, thereby causing extension portions 545 to move into and out of an adjacent position with respect to the projecting members 504.
When adjacent to the projecting members 504, the extension portions 545 prevent the projecting members 504 from deflecting inwardly toward the dispensing tray 200, as shown in
As part of the final packaging process, once the dispensing containers of the invention are filled with the desired product, the containers can be over-wrapped or over-sealed with a film material, or shrink-wrapped with such a material. The outer packaging material useful in accordance with the present invention can vary. Typically, the selection of the packaging material is dependent upon factors such as aesthetics, transparency, comfort of handling, desired barrier properties (e.g., so as to provide protection from exposure to oxygen or radiation, or so as to provide protection from loss of moisture), or the like. The packaging material preferably has the form of a film, such as a laminated film (e.g., a co-extruded laminated film). Representative materials that can be used to provide components or layers of film materials or laminated films include polyvinyl chloride, ethylene vinyl acetate co-polymer, oriented polypropylene, linear low density polyethylene, polyvinylidene dichloride, polyester terephthalate, ethylene methacrylic acid co-polymer, metallacene linear low density polyethylene, cellulosic materials (e.g., cellophane), and the like. Exemplary packaging materials can be plastic/metal films, plastic/metal films that are paper coated, plastic laminate films, or the like. US 2008/0029116 to Robinson et al. discloses examples of suitable packaging materials.
Many modifications and other embodiments of the inventions set forth herein will come to mind to one skilled in the art to which these inventions pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
