This invention generally relates to containers and more particularly to containers for smokeless tobacco.
Loose tobacco and related tobacco products are typically packaged and sold in disc-shaped containers. In many cases, the containers comprise a metal lid seated upon either a metal, plastic or cardboard can. Often, a band-type label is adhesively secured over the seam between the lid and can to securely fasten the lid and the can. The band type label also typically will positively impact the freshness of the product. The label also typically includes print, images, and information regarding the tobacco product for a potential customer.
Conventionally, the lid includes a relatively flat top portion and a surrounding skirt. The skirt terminates in a cut edge. Considering that lids are often formed from metal (plastic lids are also common), a metal edge has the potential to be relatively sharp. If the sharp edges are not properly made smooth, a purchaser of the container may potentially risk suffering a laceration in one of their fingers when prying the lid from the can using the edges. The interface between the can and the lid typically will have a snap fit to facilitate removal and attachment of the lid and the can. The interface between the lid and the can affects breathability and therefore freshness of the tobacco product contained therein. Thus, the interface between the lid and the can may include multiple configurations.
Unfortunately, the use of plastic or cardboard for forming the components of the can make the can look cheap or flimsy. However, forming a can entirely from metal can be difficult to connect the lid to the can and to provide a good repeatable connection between the lid and the can. The present invention is directed towards improvements over the state of the art.
The present invention has several aspects that may be claimed and stand as patentable independently and individually or in combination with other aspects, including but not limited to the following aspects and embodiments.
In embodiment, the invention provides a tobacco container comprising a lid, a container body and a liner. The liner releasably connects the lid to the container body. Each of the lid and container body receive and connect to the liner.
In a preferable implementation, the lid and the container body are formed of metal while the liner is formed of a self-supporting plastic.
In a further preferred implementation, the liner connects the container body and lid to one another without the two components contacting each other.
In yet another embodiment, a liner for a tobacco container is provided that includes a liner body and means for connecting a container lid to the liner and means for connecting a container body to the liner. The liner body includes a closed end wall and an annular sidewall extending from the closed end wall. The means for connecting a container lid to the liner are independent of the means for connecting a container body to the liner.
Other embodiments of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
Referring to
The container 10 may include features that make the container more aesthetically pleasing such as, for example, color, images or prints, labels, embossing, and the like. The container 10 may also be secured together by, for example, a band-type adhesive label during a packaging process. After the label has been broken, the container 10 may be repeatedly opened and closed such that the consumer may access, as often as desired, a chosen amount of the contents stored in the container 10.
As shown in
With reference to
In one embodiment, the upper end 19 of the liner 15 engages the inner surface 25 of lid 14 and provides a seal therebetween to assist in maintaining the freshness of the products stored in the container 10. In a preferred embodiment, inner surfaces of the lid 14 are coated with a gold phenolic finish. Even so, in other embodiments other types of coatings or finishes may be applied to, or formed on, these interior surfaces.
As depicted in
Referring back to
Sidewall 20 extends circumferentially around lid top 16 and downward generally perpendicularly from lid top 16.
With further reference to
The bead 38 progresses circumferentially and continuously around the entire side wall 20 of the lid 14. Therefore, as the bead 38 extends around the lid 14, the bead is unbroken and uninterrupted. Even so, in another embodiment the bead 38 may be intermittently formed such that the side wall 20 is, at discrete locations, planar all the way from shoulder 18 to just above a bottom 50 of the hem 40. In such embodiments, a thin column or portion of the side wall 20 is not bowed inwardly and instead appears flat when viewed from outside the container 10.
The hem 40 is generally a distal portion 52 of the side wall 20 folded inwardly adjacent an intermediate portion 54 of the side wall. In other words, the distal portion 52 is curled inwardly toward the lid top 16 to be in contact or almost contact with the inner surface of the remainder of the side wall 20. In the illustrated embodiment, the distal portion 52 and the intermediate portion 54 are illustrated slightly spaced apart from each other to form channel 56 between the two portions of the side wall. In the illustrated embodiment, because the hem 40 is a folded piece of metal, the hem generally need not be smoothed, ground, buffed, or otherwise machined to eliminate the terminating cut edge. The hem 40 naturally possesses a bottom 50 that is rounded and smooth. By creating a safety edge at the bottom 50 of the lid 14 through folding instead of otherwise machining as noted above, the lid may be more quickly, easily, and cost-effectively fabricated.
More features and aspects of the lid 14 can be found in co-pending U.S. patent application Ser. No. 11/680,333, entitled “Lid For A Tobacco Can” filed on Feb. 28, 2007 and assigned to the assignee of the instant application, the teachings and disclosures of which are hereby incorporated herein by reference thereto.
Referring to
The circular bottom 58 of the container body 12 includes a recessed portion 64 that is positioned radially inward from sidewall 60.
A rolled over portion 66 forms a distal end of sidewall 60. The rolled over portion 66 is formed from the distal portion of sidewall 60 opposite the circular bottom 58. The rolled over portion 66 is rolled radially inwardly and typically has a diameter of between about 0.025 and 0.065 inch and most preferably about 0.05 inch.
Referring to
The top portion 72 is received by lid 14 and more particularly in cavity 22. The bottom portion 74 is received by container body 12 and more particularly in cavity 62.
The top portion 72 includes a radially outward extending rib 78 (a.k.a., bead lock) that extends around sidewall 70. In one embodiment, rib 78 is intermittently formed such that top portion 72 is, at discrete locations, planar all the way from shoulder 18 to intermediate portion 76 to distal upper end 19. Thus, the rib 78 has a plurality of segments that are angularly spaced apart forming gaps 80 therebetween. These gaps 80 assist in venting air from the lid 14 as the lid 14 is secured to the liner 15. Even so, in another embodiment, the rib 78 may be unbroken and uninterrupted.
The bottom portion 74 includes a plurality of projections 82 extending angularly about the center point 26 of the container 10. The illustrated embodiment includes three such projections 82 angularly spaced about center point 26 forming gaps 85 therebetween. Even so, in another embodiment, the plurality of projections 82 may be replaced by a single continuous projection that extends around sidewall 70 unbroken and uninterrupted.
The projections 82 include a bottom surface 84 that extends at an angle β of between 15 degrees and 45 degrees and is preferably about 30 degrees. The projections also include a catch surface 86 facing axially away from circular bottom 68. The catch surface 86 axially engages the rolled over portion 66 of container body 12 to secure the container body 12 to the liner 15. Preferably, the catch surface 86 is generally perpendicular to sidewall 70 and is generally planar. The catch surface 86 typically extends between about 0.01 and 0.04 inches from the outer surface of the bottom portion 74 of sidewall 70, but preferably extends between about 0.02 and 0.03 inches from the outer surface of the bottom portion 74.
Further yet, bottom portion 74 can optionally include one or more axially extending ribs 88 that assist in spacing the container body 12 from the outer surface of sidewall 70 so as to provide a vent for expelling air as the liner 15 is inserted into cavity 62 of the container body 12.
With reference to
The liner 15 secures the lid 14 to the container body 12 without the container body 12 needing to directly contact the lid 14.
Rolled over portion 66 and the plurality of projections 82 provide a first cooperating catch arrangement for securing the container body 12 to the bottom portion 74 of liner 15. The rolled over portion 66 axially engages the catch surfaces 86 of the plurality of projections 82 to prevent or oppose axial removal of the liner 15 from container body 12.
Similarly, bead 38 and rib 78 provide a second cooperating catch arrangement for securing lid 14 to the top portion 72 of liner 15. The bead 38 axially engages the rib 78 to prevent or oppose axial removal of the lid 14 from liner 15.
Preferably, the engagement between bead 38 and rib 78 provides for releasable securement of lid 14 to liner 15 such that the lid 14 can be repeatably secured to and removed from liner 15. This allows the consumer to open the container 10 to remove product therefrom as desired and then to close the container 10 to secure the contents therein when finished accessing the product.
Additionally, the securement between the lid 14 and liner 15 can be overcome by a lower axial loading than the securement between the container body 12 and liner 15. As such, when a consumer is holding the container 10 by the container body 12, the consumer can remove the lid 14 by axially pulling on the lid 14 without the container body 12 being removed from the liner 15.
Top portion 72 of sidewall 70 includes several segments. A tapered segment 90 extends axially between upper end 19 and rib 78. The tapered segment 90 has an outer surface 91 that is tapered at an angle α that is between about 5 degrees and 15 degrees, but is preferably about 7 to 8 degrees, relative to inner surface 92. Inner surface 92 is preferably generally parallel to an axis running orthogonal between the lid top 16 and the circular bottom 68. The tapered configuration of tapered segment 90 assists in mounting the lid 14 to the liner 15. However, in other embodiments, the tapered segment need not be included.
An extension segment 94 extends axially between the end of the intermediate portion 76 of sidewall 70 and the bottom of rib 78. The extension segment 94, in one embodiment has a constant thickness. In an alternative embodiment, the extension segment 94 and the tapered segment 90 are merely a continuous tapered portion of sidewall 70 that merely includes a rib 78 that separates the portion into different portions.
The inclusion of intermediate portion 76 offsets the top portion 72 radially from the bottom portion 74. The intermediate portion 76 and projections 82 define relief zones 95 axially therebetween for receiving the rolled over portion 66 when the lid 14 is mounted to the liner 15.
The container body 12 preferably engages the liner 15 such that limited to no axial slop is provided therebetween. More particularly, the liner 15 preferably cannot move axially relative to the container body 12 when the container 10 is fully assembled.
With reference to
The compression lip 96 of the illustrated embodiment is a plurality of segments that form an annular hub. However, the gaps between adjacent segments of the compression lip provide venting for permitting air to escape as the liner 15 and container body 12 are secured together. However, in other embodiments the compression lip could be formed from a continuous uninterrupted segment. Further yet, the compression lip need not be circular in shape and could merely be a plurality of axially extending nibs or projections that contact the bottom wall 58 of container body 12.
As illustrated, the compression lip 96 extends axially from the outer surface 97 of the circular bottom 68 a distance D1 of between about 0.04 inch to about 0.1 inch, however, other lengths could be incorporated. Further, the compression lip 96 preferably tapers as it extends away from circular bottom 68 from a wider base portion 98 to a narrower tip 99. The taper promotes more consistent flexure of the compression lip 96 and the rigidity of the compression lip 96 increases the more the compression lip is flexed.
When the container body 12 is connected to the liner 15, the compression lip 96 is preferably biased against the inner surface of circular bottom 58 and, at least, resiliently deformed. By resiliently deforming compression lip 96, the catch surfaces 86 of projections 82 are biased into rolled over portion 66 of the container body 12. In one embodiment, the amount of biasing provided by the compression lip 96 and engagement between the rolled over portion 66 and sidewall 70 of the liner 15 is sufficient to prevent rotation of the liner 15 relative to the container body 12. It is meant by “to prevent rotation”, to mean that more than mere simple rotation by a user of the liner 15 relative to the container body 12 is required to cause relative rotation between the two components, such as for example more than 2 inch-lbs of torque.
