The present disclosure relates to containers and methods of use thereof. More particularly, the disclosure relates to packaging for products made or derived from tobacco, or that otherwise incorporate tobacco, and are intended for human consumption in a smokeless form.
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 a wide variety of consumer products, including smokeless tobacco-related products.
Tobacco may be enjoyed in a so-called “smokeless” form. Particularly popular smokeless tobacco products are employed by inserting some form of processed tobacco or tobacco-containing formulation into the mouth of the user. See for example, the types of smokeless tobacco formulations, ingredients, and processing methodologies set forth in U.S. Pat. No. 1,376,586 to Schwartz; U.S. Pat. No. 3,696,917 to Levi; U.S. Pat. No. 4,513,756 to Pittman et al.; U.S. Pat. No. 4,528,993 to Sensabaugh, Jr. et al.; U.S. Pat. No. 4,624,269 to Story et al.; U.S. Pat. No. 4,991,599 to Tibbetts; U.S. Pat.

Nos. 2004/0020503 to Williams; 2005/0115580 to Quinter et al.; 2005/0244521 to Strickland et al.; 2006/0191548 to Strickland et al.; 2007/0062549 to Holton, Jr. et al.; 2008/0029116 to Robinson et al.; 2008/0029117 to Mua et al.; 2008/0173317 to Robinson et al.; 2008/0196730 to Engstrom et al.; 2008/0209586 to Neilsen et al.; 2008/0305216 to Crawford et al.; 2009/0065013 to Essen et al.; 2009/0293889 to Kumar et al.; and 2010/0291245 to Gao et al.; PCT Pub. Nos. WO 04/095959 to Arnarp et al.; and WO 10/132,444 to Atchley; each of which is incorporated herein by reference.
Representative smokeless tobacco products that have been marketed include those referred to as CAMEL Snus, CAMEL Orbs, CAMEL Strips and CAMEL Sticks by R. J. Reynolds Tobacco Company; GRIZZLY moist tobacco, KODIAK moist tobacco, LEVI GARRETT loose tobacco and TAYLOR'S PRIDE loose tobacco by American Snuff Company, LLC; KAYAK moist snuff and CHATTANOOGA CHEW chewing tobacco by Swisher International, Inc.; REDMAN chewing tobacco by Pinkerton Tobacco Co. LP; COPENHAGEN moist tobacco, COPENHAGEN Pouches, SKOAL Bandits, SKOAL Pouches, RED SEAL long cut and REVEL Mint Tobacco Packs by U.S. Smokeless Tobacco Company; and MARLBORO Snus and Taboka by Philip Morris USA.
Representative types of snuff products, commonly referred to as “snus,” are manufactured in Europe, particularly in Sweden, by or through companies such as Swedish Match AB, Fiedler & Lundgren AB, Gustavus AB, Skandinavisk Tobakskompagni A/S and Rocker Production AB. Snus products available in the U.S.A. are marketed under the trade names such as CAMEL Snus Frost, CAMEL Snus Original and CAMEL Snus Spice by R. J. Reynolds Tobacco Company.
Snus products, such as CAMEL Snus Original, are commonly supplied in small teabag-like pouches. The pouches are typically a nonwoven fleece material, and contain about 0.4 to 1.5 grams of pasteurized tobacco. These products typically remain in a user's mouth for about 10-30 minutes. Unlike certain other smokeless tobacco products, snus does not require expectoration by the user.
Snus products have been packaged in tins, “pucks” or “pots” that are manufactured from metal or plastic such as those disclosed in U.S. Pat. No. 4,098,421 to Foster and U.S. Pat. No. 4,190,170 to Boyd, and U.S. Patent Pub. Nos. 2010/0065076 to Bergstrom et al.; and 2010/0065077 to Lofgreen-Ohrn et al.; each of which is incorporated by reference herein.
A 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. In other instances, venting within the enclosure formed by the container may be needed for properly storing a product.
It would thus be desirable to provide an improved packaging for smokeless tobacco products and the like, wherein the packaging is aesthetically pleasing and provides various advantageous features, such as protection from environmental effects by venting the container.
The present disclosure provides a container that, in certain embodiments, combines aesthetics and environmental protection of a product, and which can be provided in a convenient handheld size. The type and form of the product to be stored can vary.
In one embodiment, the container of the disclosure comprises a body having a bottom wall and a side wall. The bottom wall and the side wall define an internal storage compartment adapted for storage of a plurality of units of a product. The side wall has an outer peripheral surface. A rib structure is engaged with the body about the outer peripheral surface of the side wall and extends outwardly therefrom. A cover is configured to be removably engaged with the body. The cover includes a top wall and a peripheral flange having an inner surface. The inner surface is substantially smooth and is configured to interact with the rib structure when the cover is received over the outer peripheral surface of the side wall so as to form an interference fit.
In another aspect, the disclosure provides a container comprising a polymeric body having a bottom wall and a cylindrical side wall. The bottom wall and the side wall define an internal storage compartment adapted for storage of a plurality of units of a product. The side wall has an outer peripheral surface. A circumferential rib structure is integrally formed with the polymeric body about the outer peripheral surface of the side wall and extends radially outwardly therefrom. The rib structure comprising a plurality of ribs extending circumferentially about the outer peripheral surface of the side wall. The ribs are spaced apart so as to form channels therebetween for facilitating venting. A metallic cover is configured to be removably engaged with the polymeric body. The metallic cover includes a top wall and a peripheral flange having a cylindrical inner surface. The cylindrical inner surface is substantially smooth and is configured to interact with the rib structure when the metallic cover is received over the outer peripheral surface of the side wall so as to form an interference fit.
In yet another aspect, the disclosure provides a polymeric body having a bottom wall and a cylindrical side wall having an edge. The bottom wall and the side wall define an internal storage compartment adapted for storage of a plurality of units of a product. The internal storage compartment has an opening thereto adjacent to the edge of the side wall, wherein an outer peripheral surface of the side wall comprises a neck region of reduced diameter proximal to the edge of the side wall such that the side wall defines a lip. A circumferential rib structure is integrally formed with the polymeric body about the outer peripheral surface of the side wall in the neck region and projects radially outwardly therefrom. The rib structure includes a plurality of rib segments extending circumferentially about the outer peripheral surface of the side wall. The rib segments are spaced apart so as to form vent channels therebetween and each rib segment includes a rib wall projecting radially from the outer peripheral surface of the body and a rib projection projecting radially from the rib wall. Each vent channel is at least partially defined by adjacent rib walls and the outer peripheral surface of the side wall of the body. A metallic cover is configured to be removably engaged with the polymeric body. The metallic cover has a top wall and a peripheral flange having a cylindrical inner surface. The cylindrical inner surface is substantially smooth and is configured to interact with the rib structure when the metallic cover is received over the neck region of the side wall so as to form an interference fit, and wherein the metallic cover is configured to abut the lip of the side wall of the body when the metallic cover is fully seated on the body.
These and other features, aspects, and advantages of the disclosure 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 disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present disclosure now will be described more fully hereinafter with reference to certain preferred aspects. These aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the aspects set forth herein; rather, these aspects 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 any solid products, but are particularly well-suited for products designed for oral consumption. Exemplary consumable products that are often packaged in such containers include a wide variety of consumer products, including tobacco products in smokeless form.
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. Further, exemplary tobacco products include tobacco formulations in a loose form such as, for example, a moist snuff product. Exemplary loose form tobacco used with the containers of the present disclosure may include tobacco formulations associated with, for example, commercially available GRIZZLY moist tobacco products and KODIAK moist tobacco products that are marketed by American Snuff Company, LLC.
Exemplary smokeless tobacco compositions that can be packaged in the containers of the present disclosure are set forth in, for example, U.S. Pat. No. 1,376,586 to Schwartz; U.S. Pat. No. 3,368,567 to Speer; U.S. Pat. No. 4,513,756 to Pittman et al.; U.S. Pat. No. 4,606,357 to Dusek et al; U.S. Pat. No. 4,821,749 to Toft et al.; U.S. Pat. No. 5,167,244 to Kjerstad; U.S. Pat. No. 5,387,416 to White; U.S. Pat. No. 6,668,839 to Williams; U.S. Pat. No. 7,810,507 to Dube et al.; U.S. Pat. No. 7,819,124 to Strickland et al.; U.S. Patent Pub. Nos. 2005/0244521 to Strickland et al.; 2006/0191548 to Strickland et al.; and 2008/0029116 to Robinson et al. 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 U.S. Patent Pub. Nos. 2004/0217024 and 2006/0118589 to Arnarp et al.; and 2009/0014450 to Bjorkholm; and PCT Pub. Nos. 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 disclosure 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, U.S. Pat. No. 7,861,728 to Holton et al., which is incorporated by reference herein in its entirety.
The tobacco formulation can be contained within a container, such as a pouch or bag, such as is the type commonly used for the manufacture of snus types of products (e.g., a sealed, moisture permeable pouch that is sometimes referred to as a “portion”). A representative moisture permeable pouch can be composed of a “fleece” type of material. The tobacco formulation is in turn contained within a package, such as the containers of the present disclosure described more fully hereinbelow. The package is sealed tightly, and is composed of a suitable material, such that the atmospheric conditions within that sealed package are modified and/or controlled. That is, the sealed package can provide a good barrier that inhibits the passage of compositions such as moisture and oxygen therethrough. In addition, the atmosphere within the sealed package can be further modified by introducing a selected gaseous species (e.g., nitrogen, argon, or a mixture thereof) into the package prior to sealing or by drawing a vacuum therein (vacuum sealing). As such, the atmospheric conditions to which the tobacco composition is exposed are controlled during conditions of preparation, packing, storage and handling.
An exemplary pouch may be manufactured from materials, and in such a manner, such that during use by the user, the pouch undergoes a controlled dispersion or dissolution. Such pouch materials may have the form of a mesh, screen, perforated paper, permeable fabric, or the like. For example, pouch material manufactured from a mesh-like form of rice paper, or perforated rice paper, may dissolve in the mouth of the user. As a result, the pouch and tobacco formulation each may undergo complete dispersion within the mouth of the user during normal conditions of use, and hence the pouch and tobacco formulation both may be ingested by the user. Other exemplary pouch materials may be manufactured using water dispersible film forming materials (e.g., binding agents such as alginates, carboxymethylcellulose, xanthan gum, pullulan, and the like), as well as those materials in combination with materials such as ground cellulosics (e.g., fine particle size wood pulp). Preferred pouch materials, though water dispersible or dissolvable, may be designed and manufactured such that under conditions of normal use, a significant amount of the tobacco formulation contents permeate through the pouch material prior to the time that the pouch undergoes loss of its physical integrity. If desired, flavoring ingredients, disintegration aids, and other desired components, may be incorporated within, or applied to, the pouch material. Descriptions of various components of snus products and components thereof also are set forth in U.S. Pat. Pub. No. 2004/0118422 to Lundin et al., which is incorporated herein by reference. See, also, for example, U.S. Pat. No. 4,607,479 to Linden; U.S. Pat. No. 4,631,899 to Nielsen; U.S. Pat. No. 5,346,734 to Wydick et al.; and U.S. Pat. No. 6,162,516 to Derr, and U.S. Pat. Pub. No. 2005/0061339 to Hansson et al.; each of which is incorporated herein by reference. See, also, the representative types of pouches, and pouch material or fleece, set forth in U.S. Pat. No. 5,167,244 to Kjerstad, which is incorporated herein by reference. Snus products can be manufactured using equipment such as that available as SB 51-1/T, SBL 50 and SB 53-2/T from Merz Verpackungmaschinen GmBH. G.D SpA out of Italy also supplies tobacco pouching equipment. Snus pouches can be provided as individual pouches, or a plurality of pouches and can be connected or linked together (e.g., in an end-to-end manner) such that a single pouch or individual portion can be readily removed for use from a one-piece strand or matrix of pouches.
The shape of the outer surface of the containers of the disclosure 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 disclosure 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 disclosure. However, in preferred embodiments, the containers of the disclosure can be described as having a cylindrical size suitable for handheld manipulation and operation. Exemplary dimensions for such handheld cylindrical embodiments include diameters in the range of about 50 mm to about 100 mm, and more typically about 60 mm to about 80 mm. Exemplary wall thicknesses include the range of about 0.5 mm to about 1.5 mm, and more typically about 0.8 mm to about 1.4 mm. Exemplary depths for handheld container embodiments of the present disclosure range from about 5 mm to about 50 mm, more typically about 8 mm to about 30 mm, and most often about 15 mm to about 25 mm. An exemplary general outward appearance of the container is that used for commercially available GRIZZLY and KODIAK products that are marketed by American Snuff Company, LLC.
The number of solid product units stored in the containers of the disclosure 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 cover 40 may be provided for enclosing the units of product within the internal storage compartment 26. In this regard, the cover 40 is typically removably secured to the body 20 by a snap-fit or an interference fit. As shown in
The material of construction of the container 10 can 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 a preferred embodiment, the body 20 is formed from a polymeric material, while the cover 40 is formed from a metallic material such as, for example, aluminum or tinplate. Such a configuration is advantageous in that it provides an aesthetically appealing appearance by using a metallic cover 40 (which is typically stamped), while also allowing the body to be less expensively produced using, for example, an injection molding process. In this manner, a rib structure (as further described below) may be more easily and less expensively applied to the body 20 (i.e., via plastic injection molding instead of metallic stamping). Exemplary covers formed from metallic materials are those used for commercially available CAMEL Snuff, GRIZZLY and KODIAK products that are marketed by American Snuff Company, LLC. Exemplary bodies are those that incorporate polymeric materials such as those types of materials used for the same products.
As particularly shown in
Each rib segment 62 is separated from the next adjacent rib segment 62 by a vent channel 64. Each rib segment 62 may include a rib wall 66 and a rib projection 68. In some instances, as shown in
In some instances, the rib structure 60 may be positioned adjacent to the lip 32, wherein the top edge 38 of the side wall 24 can engage the surface 36 of the lip 32 in such a manner that the outer peripheral surface 28 of the body 20 is substantially flush with the outer surface 48 of the cover 40. In other words, in some instances, the peripheral flange 44 of the cover 40 may not be deflected by the rib structure 60 to such a degree that causes the peripheral flange 44 to extend beyond the lip 32.
The rib projections 68 project radially outward from the outer peripheral surface 28 and the neck region 34 (when provided). Although the rib projections 38 are shown in spaced relation to the top edge 38 of the body 20, the position of the rib projections may vary in relation to the top edge, meaning the rib projection could be moved closer or further away from the top edge without departing from the present disclosure. In some instances, the rib projections 68 have a substantially arcuate or rounded profile, although other configurations may also be employed, such as, for example, a configuration in which the rib projection 68 terminates at a substantially sharp edge (not shown) outward of the outer peripheral surface 28. As shown in
Exemplary dimensions for the rib projections 62 include heights in the range of about 0.05 millimeters to about 0.25 millimeters, and widths in the range of about 1 millimeter to about 1.5 millimeters. As used herein, height refers to the major dimension of the rib projection that extends from the outer peripheral surface 28, as indicated by reference character A (
As part of the final packaging process, once the containers of the disclosure are filled with the desired product, the containers can be sealed with a circumferential label or wrapper of a pervious or impervious material. The label or wrapping material useful in accordance with the present disclosure can vary. Typically, the selection of the packaging label or wrapper is dependent upon factors such as aesthetics, desired barrier properties (e.g., so as to provide protection from exposure to oxygen, or so as to provide protection from loss of moisture), or the like.
Many modifications and other aspects of the disclosure set forth herein will come to mind to one skilled in the art to which the disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosure is not to be limited to the specific aspects disclosed and that modifications and other aspects 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.
