DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a container 10 is illustrated. As will be explained more fully below, the container 10 is preferably dimensioned and designed to be compatible with a hand and, more specifically, the palm of a hand. The container 10 is uncomplicated to open and close and is, preferably, easily manipulated between closed and open positions (and back again) using a finger and/or thumb. Further, the container 10 is able to repeatedly alternatively dispense and store products such as consumable tablets. By way of example, such consumable tablets include, but are not limited to, candy, gum, mints, pills, and the like. As shown in FIG. 1, the container 10 comprises a base 12, a cover 14, a slider 16 (a.k.a., a door), and a storage area 18 disposed within the container.

The generally rectangular base 12 includes a bottom 20, front and back walls 22, 24, and a pair of side walls 26, 28. As shown, the bottom 20 is generally planar or flat. The front and back walls 22, 24 generally extend upwardly from the bottom 20 proximate a bottom periphery 30 and terminate in distal ends 32, 34. In the illustrated embodiment, the front and back walls 22, 24 are integrally formed with the bottom 20. Also, where the front and back walls 22, 24 are joined with the bottom 20 the base 12 is generally radiused to form a smooth, rounded surface. As shown, the front and back walls 22, 24 are generally transverse to, and spaced apart from each other by, the bottom 20.

The side walls 26, 28 also generally extend upwardly from the bottom 20 proximate the bottom periphery 30 and terminate in distal ends 36, 38. In the illustrated embodiment, the side walls 26, 28 are integrally formed with the bottom 20. Also, where the side walls 26, 28 are joined with the bottom 20 the base 12 is generally radiused to form a smooth, rounded surface. As shown, the side walls 26, 28 are generally transverse to the bottom 20, transverse to the front and back walls 22, 24, and spaced apart from each other by the bottom. As such, the base 12 generally forms a lower portion 40 of the storage area 18. The base 12 is preferably formed from plastic and is molded. However, a variety of other materials may be possible.

The generally rectangular cover 14 includes a top 42, front and back walls 44, 46, and a pair of side walls 48, 50. The front and back walls 44, 46 generally extend downwardly from the top 42 proximate a top periphery 52 and terminate in distal ends 54, 56. In the illustrated embodiment, the front and back walls 44, 46 are integrally formed with the top 42. Also, where the front and back walls 44, 46 are joined with the top 42 the cover 14 is generally radiused to form a smooth, rounded surface. As shown, the front and back walls 44, 46 are generally transverse to, and spaced apart from each other by, the top 42.

The side walls 48, 50 also generally extend downwardly from the top 42 proximate the top periphery 52 and terminate in distal ends 58, 60. In the illustrated embodiment, the side walls 48, 50 are integrally formed with the top 42. Also, where the side walls 48, 50 are joined with the top 42 the cover 14 is generally radiused to form a smooth, rounded surface. As shown, the side walls 48, 50 are generally transverse to the top 42, transverse to the front and back walls 44, 46, and spaced apart from each other by the top 42. The cover 14 generally forms an upper portion 62 of the storage area 18. In addition, the cover 14 is preferably formed from plastic and is molded. However, a variety of materials may be possible.

When operably coupled together, the base 12 and the cover 14 collectively form the storage area 18 found inside the container 10 of FIG. 1. The base 12 and the cover 14 are operably coupled together in a variety of different ways as well known to those skilled in the art. For example, in one embodiment, the base 12 and the cover 14 are operably coupled together by a friction fit (i.e., interference fit) and by mating axial flanges which may include interlocking snaps. As shown in FIG. 5, an interlocking mechanism 39 including pins 41 and barrels 43 may also be used in the alternative or in addition to other methods of securing the base 12 and cover 14. The base 12 and the cover 14 may be molded as separate parts of as a single, folded-over part whereby the base and the cover are unitarily connected together by a living hinge. Where the living hinge is used, a latch assembly is often employed to keep the cover and the base secured together. In yet another embodiment, the base 12 and the cover 14 are operably coupled by an adhesive, through ultrasonic bonding, and the like.

The base 12 and cover 14 preferably are permanently snapped together and thus not manually removable except with tool or extraordinary force. However, if a consumer desires to have ready access to the entire contents of the container 10, the base 12 and the cover can be releasably secured to each other. Preferably, the base 12 and the cover 14 are joined such that outer surfaces 64 of the container 10 between the top and bottom peripheries 52, 30 are generally smooth.

Still referring to FIG. 1, the top 42 of the cover 14 includes a generally rectangular recess 66 surrounded by a border 68. An upwardly-facing surface 70 of the top 42 within the recess 66 is disposed vertically below a top surface 72 of the border 68. Front and back recess walls 74, 76 and recess side walls 78, 80. The recess front and back walls 74, 76 and the recess side walls 78, 80 are generally transverse to each other and to the surfaces 70, 72. The recess 66 also preferably includes a recess bottom wall 71.

The top 42 also includes a pair of elongate, linear slots 82, which may be located in the recess 66. As shown, the slots 82 are formed within the recess 66 and through the top 42 proximate an intersection of the recess side walls 78, 80 and the upwardly-facing surface 70 of the recess 66. The slots 82 are generally parallel to each other and centrally located within the recess 66 between the recess front and back walls 74, 76. The slots 82 pass entirely through the top 42 and open up to the upper portion 62 of the storage area 18 within the container 10. Thus, no holes other than the dispensing port 88 may be in the top 42 and this avoids interference between the slider 16 and the contents of the container 10 held within the storage area 18 during movement of the slider.

As illustrated in FIG. 2, in another embodiment the top 42 includes a pair of tracks 86 instead of slots 82. The tracks 86 are generally formed in the top 42 in a location similar to that of the slots 82 depicted in FIG. 1. However, the tracks 86 extend into the recess side walls 78, 80 and do not open up to the storage area 18.

Referring back to FIG. 1, the top 42 of the cover 14 includes a dispensing port 88. The dispensing port 88 is formed through the top 42 within the recess 66 and opens up to the storage area 18 within the container 10. The dispensing port 88 is sized, dimensioned, and otherwise configured to easily dispense the consumable tablets (not shown) held within the storage area 10 when the dispensing port is uncovered, as will be more fully explained below.

In the illustrated embodiment, the dispensing port 88 is located near the front wall 44 of the cover 14 and, in particular, proximate an intersection of one of the recess side walls 80 and recess front wall 74. In other words, the dispensing port 88 is generally situated in a corner of the recess 66. Also, in the illustrated embodiment, the dispensing port 88 is depicted as having a circular shape. However, other shapes are suitably employed such as, for example, square, rectangular, elliptical, triangular, and the like.

As depicted in FIG. 1, the slider 16 is generally rectangular, yet has rounded corners 90. The slider 90 is preferably formed from metal. Advantageously, this provides the look, design options, and lithography printing options available with metal (that are not available with plastic) while at the same time permitting a simple to mold plastic container 10 (not including the slider 16). When the slider is formed from metal, portions of the front and back ends 92, 94 and sides 96 of the slider 16 are folded over and/or crimped to ensure a smooth outer periphery 98 known as a safety edge. Other materials, including plastic, may be used for the slider 16.

In one embodiment as shown in FIG. 3, a bottom surface 100 of the slider 16 is coated or treated with a substance or material 102 (a portion of which has been removed for the purpose of illustration) having a reduced coefficient of friction relative to sheet metal. For example, the bottom surface 100 is coated with polytetrafluorethylene (PTFE), overlaid with a smooth finishing paint, and the like. In another embodiment, the material 102 overlaying the bottom surface 100 is in the form of a sheet or layer. The layer is held in place by the folded over and/or crimped portions of the front and back ends 92, 94 and sides 96 described above. If desired, an adhesive substance may alternatively or additionally be employed to secure the material 102 to the bottom surface. In addition to reducing drag between the slider 16 and surfaces the that slider moves over, as will be explained more fully below, the reduced friction material 102 permits the slider to have a more uniform overall thickness 104 from the top surface 106 of the slider to a bottom surface 108 of the material 102. In this manner, the crimped edges noted above will not substantially engage the surface 70.

Referring back to FIG. 1, the top surface 106 of the slider 16 includes a knurl 110 (or pattern of knurls) formed thereon and projecting upwardly away from the top surface. The knurl 110 provides a raised surface that permits a finger or thumb to grip the otherwise planar top surface 106 of the slider 16. As will be more fully explained below, the knurl 110 is employed when moving the slider 16 relative to the cover 14. In lieu of or in addition to the knurl 110, in one embodiment a de-bossed nib projecting downwardly into slider 16 away from the surface 106 with a corresponding recess on the surface 70 of the cover 14 could also be used to keep the container closed.

In one embodiment the top surface 106 of the slider 16 includes a lithographic image or print formed thereon. Again, this is an advantage of using metal for the slider 16. In the event plastic is used for the slider 16, the top surface 106 carries a label secured to the top surface by an adhesive. The image, print, and/or label is employed for marketing reasons to make the container 10 more aesthetically pleasing to a consumer and to convey information to the consumer about the contents.

The slider 16 also includes guide members 112, 114 that are integrally formed with the remainder of the slider. As illustrated in FIG. 5, the guide members 112, 114 begin proximate the sides 96 of the slider 16 and extend generally downwardly away from the bottom surface 100. The guide members 112, 114 are disposed approximately centrally between a front and back ends 92, 94 of the slider 16. To isolate or protect product within the storage area 18, the base 12 includes ribs 95 that project upwardly from the base within the lower storage area 40 as shown in FIGS. 1 and 5. The ribs 95 are generally parallel to the side walls 26, 28 and are unitarily formed with the base 12.

When the container 10 is fully assembled, the slider 16 is generally disposed within the recess 66 found in the top 42 of the cover 14. In that regard, with the exception of the knurl 110, the top surface 106 of the slider 16 is substantially coplanar with the border 72. In one embodiment, the top surface 106 of the slider 16, not including the knurl 110, does not project above the top surface 72 of the border 68. In another embodiment, the top surface 106 of the slider 16, not including the knurl 110, projects about one sixteenth of an inch or less above the top surface 72 of the border 68. Also, in one embodiment a rear portion of the border 72 is removed such that the back wall 76 is eliminated. Therefore, if the slots 82 or tracks 86 are of sufficient length, the slider 16 may be slid rearwardly until a portion of the slider projects outwardly and extends past the back wall 46 of the cover.

Further, as shown in FIG. 1, a width 116 of the slider 16 generally corresponds to a width 118 of the recess 66. However, a length 120 of the slider 16 is less than a length 122 of the recess 66. In fact, the difference between the two lengths 120, 122 is approximately equal to a diameter 124 (or largest expanse) of the dispensing port 88.

In addition, the slider 16 is operably coupled to the cover 14 such that the slider is able to move back forth within the recess 66 toward and away from the front and back recess walls 74, 76. As depicted in FIGS. 4 and 5, in one embodiment the guide members 112, 114 of the slider 16 pass through the slots 82 in the cover 14 and extend into the storage area 18. As shown, the ends 126, 128 of the guide members 112, 114 are curled, folded, crimped, bent or otherwise configured to keep the slider 16 and the cover 14 secured together while still permitting relative movement between the two.

In the embodiment depicted in FIG. 6, the ends 130, 132 (a.k.a., extended safety edges) of the guide members 112, 114 of the slider 16 extend into and engage the tracks 86 to operably couple the slider to the cover 14. In such an embodiment, the ends 130, 132 of the guide members 112, 114 do not enter the storage area 18 and, as a result, have no direct contact with the consumable tablets temporarily stored therein. Even so, the slider 16 is still able to translate back and forth within the recess 66 or relative to the cover 14.

In operation, when the slider 16 and the container 10 are in the closed position as shown in FIG. 7, the front end 92 of the slider 16 is positioned proximate the front recess wall 74. As such, a forward portion of the slider 16 covers the dispensing port 88 (FIG. 1) and prevents the consumable tablets held within the storage area 18 from being dispensed. As shown, a portion of the recess 66 behind the slider 16 is exposed.

To transition the slider 16 and the container 10 into the open position as shown in FIG. 8, the user of the container engages the knurl 110 on the top surface 106 of the slider 16 with a thumb or finger and applies a biasing force directed toward the back recess wall 76. When the biasing force exceeds the force of friction between the bottom surface 100 of the slider 16 (or the bottom surface 108 of the reduced friction material 102), the slider 16 begins to move toward the back recess wall 76. After the slider 16 has traveled a sufficient distance, the dispensing port 88 is exposed. Therefore, the dispensing port 88 is permitted to controllably dispense the consumable tablets held within the storage area 18.

To move the slider 16 back to the closed position, the user of the container again engages the knurl 110 on the top surface 106 of the slider 16 with a thumb or finger and applies a biasing force directed toward the front recess wall 74 (as shown by biasing force arrow 156 in FIGS. 4 and 8). When the biasing force exceeds the force of friction between the bottom surface 100 of the slider 16 (or the bottom surface 108 of the reduced friction layer 102), the slider 16 begins to move toward the front recess wall 74. After the slider 16 has traveled a sufficient distance, the dispensing port 88 is once again covered. Therefore, the dispensing port 88 is again prevented from dispensing the consumable tablets held within the storage area 18.

In one embodiment, as the slider 16 is transitioned between the open and closed positions, the slider employs the recess front wall 74, the recess back wall 76, a wall 134 within the slot 82 (see FIG. 4), and/or a wall 136 within the track 86 (see FIG. 2) as a stop to prevent further travel of the slider within the recess. The different potential stops are used either alone or in combination.

Also, in one embodiment friction is able to maintain the slider in either the closed position of FIG. 7 or the open position of FIG. 8 (or somewhere in between) after the slider 16 has been manipulated into those positions by the consumer. In other words, the friction existing between the slider 16 and the cover 14 is sufficient to prevent the slider from freely moving back and forth within the recess 66 until an external biasing force is exerted upon the knurl 110 by the consumer.

To provide hand-held ergonomic features suitable for typical tablet containers, and with reference to FIG. 8, the container 10 may have a length 138 from the front 140 to the back 142 of between about two and about four inches, a width 144 from one side 146 to an opposing side 148 of between about one and about three inches, and/or a thickness 150 from top 152 to bottom 154 of between about one quarter inch to about one inch.
