This invention generally relates to containers and more particularly to containers for holding large numbers of small products such as smokeless tobacco or small candy pieces.
Containers for storing products are generally well known in the art. One particular example where containers are used to store products is the use of a container to store 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.
Typically, the user will pinch the product between the thumb and a forefinger to accumulate product and remove it from the can. Unfortunately, as the product is used, the product settles to the bottom of the can making it more difficult to pinch and remove from the can. The settling effect of product within a container is not unique to smokeless tobacco. This may also occur with small product such as for example, small candy pieces including mints, small chocolates, hard coated chocolates or gums.
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.
In one aspect, the invention provides a container comprising a lid, a container bottom and a compactor. The compactor is positioned within a cavity of the container bottom and adjusts a size of a storage portion of the cavity. The adjustment of the size of the storage portion reduces the volume in which stored product can be distributed to cause the product to collect, accumulate and/or compact.
In one particular embodiment, the lid engages the compactor such that the user can adjust the relative position of the lid and the container bottom to adjust the position of the compactor. In additional embodiments, the compactor and container bottom may have cooperating indexing structure to maintain the position of the compactor after it has been adjusted by the user. However, the indexing structure is only sufficiently secure that the user can then again adjust the position of the compactor when desired.
In another embodiment of the present invention a container is provided that includes a compactor arrangement within the cavity defining a storage portion of the cavity, the compactor arrangement at least partially selectively movable relative to the container bottom to adjust the size of the storage portion of the cavity.
In another implementation of the invention, a method of compacting loose products contained within a container is provided. The method comprising the step of selectively adjusting a storage portion of a cavity of the container to reduce the size of the cavity in which the loose product is stored.
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.
With further reference to
Prior to sale, the container 10 may be held together by aesthetically pleasing band type labels which may contain a company's logo or name, or other designs (not shown), which may also provide for sealing the container during storage to maximize the shelf-life of the product stored within the container 10. Upon removal of or tearing of the label, a consumer is able to remove and reattach the lid 12 as many times as desired so as to be able to access the products stored in the container 10.
As illustrated in
With reference to
The top wall 24 of the illustrated embodiment includes a circular recessed inner portion 23 typically for locating advertising labels; other embodiments of the invention may not necessarily include the recessed inner portion. The outer surfaces of the top wall 24 or cylindrical skirt may be sufficiently textured such as by including stippling, ribs, grooves, dimples, projections, etc. to facilitate easy gripping of the lid 12.
Referring to
The skirt 26 of the lid 12 projects downwardly from the top wall 24 and has a diameter large enough to receive a top end of the sidewall 48 of the bottom 16. The skirt 26 includes an inwardly extending bead 36, which engages cooperating structure of the bottom 16 to releasably secure the lid 12 in place. The bead 36 is continuous around the entire inner surface 38 of the skirt 26, however in other embodiments this may not necessarily be the case and could be formed from a plurality of nibs or bead segments. Alternatively, a groove could be provided that receives a bead formed on the container bottom 16.
The bottom 16 of the container comprises a circular bottom wall 46 with a cylindrical sidewall 48 formed integrally with and extending from the bottom wall 46 forming cavity 17. As illustrated in
In other embodiments of the invention, the bottom wall may take on other shapes, such as the rectangular shape illustrated in the embodiment of
As illustrated in
Returning to
The recessed neck portion 58 further contains an outwardly extending bead 60 extending from an outer surface 61. The bead 60 interacts with corresponding bead 36 of lid 12. The bead 60 continues uninterrupted around the entire outer surface 61 of the neck portion 58. However in other embodiments of the illustrated invention, this may not be the case and bead 60 may be formed by a plurality of projections. The interaction of bead 60 and bead 36 allows the lid 12 to be releasably connected to the bottom 16.
In this embodiment, the inner surface 64 of the sidewall 48 is smooth to facilitate easy turning of the compactor 14 placed within it.
In preferred embodiments, illustrated in
In this embodiment, the bottom wall 46 of the bottom 16 includes an upwardly projecting integrally formed compactor wall 62 (see
The compactor wall 62 is generally rectangular in shape and extends from inner surface 52 of the bottom wall 46. The compactor wall 62 preferably has a height similar to the height of sidewall 48. Further, the compactor wall 62 extends radially from a central location of the container bottom 16. In a preferred embodiment, the compactor wall 62 does not radially contact the central location or center point so as to facilitate rotation of the compactor 14. Further, the compactor wall 62 and sidewall 48 preferably form a gap 63 radially therebetween to accommodate the cylindrical wall 70 of the compactor 14. This gap 63 permits the compactor 14 to be axially inserted into container bottom 16 without axial interference between the sidewall 70 and compactor wall 62.
The compactor 14 of the container 10 comprises a cylindrical wall 70 and a compactor blade 72. The wall 70 has an outer diameter small enough to provide a clearance to allow it to rest within the sidewall 48 of the bottom 16 and the skirt 26 of the lid 12. The wall 70 also has a thickness that is small enough that will allow it to rest within the recessed outer portion of the inner surface 52 of the bottom 16, and still allow angular movement within the bottom 16.
With reference to
With the lid removed, the compactor 14 in this embodiment floats axially in the bottom 16 of the container 10. However, as indicated previously, in other embodiments, the compactor 14 may contain an outwardly extending bead 80 to axially maintain the compactor 14 within container bottom 16. With reference to
Returning again to
The ability to rotate the compactor 14 relative to bottom 16 is illustrated in
With reference to
As illustrated in the progression from
Once the product becomes too shallow or sufficiently unpacked in this new orientation of the compactor blade 72 relative to compactor wall 62 (see
With reference to
This interaction of the indexing structure, i.e. ribs/serrations 84, 86 provides some engagement between the bottom 16 and compactor 14 to maintain the compactor 14 in a desired indexed location, and more particularly compactor blade 72. However, the engagement therebetween will be less than that of the lid 12 and the compactor 14, such that the user can still facilitate movement between the compactor 14 and bottom 16 when the lid 12 is turned. In this embodiment, the indexing structures radially engage one another.
Similarly, in other embodiments as illustrated in
Alternatively, the indexing structure could be formed radially inward from sidewall 70 and could be formed by compactor blade 72 and interact with corresponding structure formed in bottom wall 46.
However, the arrangement illustrated in
A further embodiment of a container 200 according to the teachings of the present invention is illustrated in
The container includes a compactor 214 for adjusting the storage volume of the cavity defined by the bottom 216 of the container 200. The compactor 214 can be moved axially along the container bottom 216 to collect and pack product stored within the container bottom 216, much like compactor 14 of previous embodiments. However, rather than rotating about a central axis, this compactor 214 moves axially.
In this embodiment, a handle 218 of the compactor 214 extends axially through a slot 220 defined in the lid 212. The handle 218 can be grasped by the user to bias the compactor along or parallel to longitudinal axis 217 of the container 212.
The compactor 214 also includes a compactor blade 272 that actually separates cavity 219 of the container bottom 216 into a storage volume (i.e. the section that includes product) and an empty volume (the section that is void of any product), like compactor blade 72 of the previous embodiments.
The handle 218 is operably coupled to compactor blade 272 to facilitate positioning the compactor blade 272. In the illustrated embodiment, handle 218 and compactor blade 272 are separate components. However, in alternative embodiments, the two components may be integrally formed in a unitary one-piece body.
Further, the compactor 214 may include indexing structure like the prior embodiments to maintain the axial position of the compactor 214 relative to the container bottom 216 and container lid 212 when the container 200 is not being accessed by a user.
The two part configuration of the illustrated embodiment facilitates easier removal of the lid 212. However, alternative configurations of the handle 218 may be implemented to facilitate arrangements where the entire compactor 214 remains with the container bottom 216 when the lid 212 is removed therefrom.
This embodiment illustrates, that other structures may be used, other than the lid, to manipulate the position of the compactor relative to the container bottom of the container. Further, a compactor need not necessarily be able to be manipulated when the lid is attached to the container bottom. For example, a container may only include a container bottom such as container bottom 216 and a compactor blade 272 but have a solid lid. In such an arrangement, the user must push the compactor blade 272 by hand when the lid is removed from the container.
