ORAL CARE INSTRUMENT AND PACKAGE THEREFORE

FIELD OF THE INVENTION

The present invention pertains to a personal hygiene device, more particularly to a personal hygiene device including a force indication system and a package therefore.

BACKGROUND OF THE INVENTION

The utilization of toothbrushes to clean one's teeth has long been known. During the brushing process, a user generally applies a force to the brush which is applied against the teeth and gums by the cleaning elements of the toothbrush. A minimum level of force must be applied to remove plaque and debris; however, high levels of force may have negative health consequences for an individual. For example, issues such as gum irritation, or over periods of time, gum recession or tooth enamel abrasion may occur. Unfortunately, the presence of these issues may exacerbate a contributing factor to the issues, i.e. high brushing force. Because some users may feel that these issues stem from poor cleaning, in an effort to correct the issues the users may apply even more force during brushing which in turn may cause more gum irritation and/or gum recession or tooth enamel abrasion.

In order to avoid or mitigate these issues, dental professionals may recommend the use of a soft bristled toothbrush. However, the use of a soft bristled toothbrush does not preclude the application of high brushing forces to the oral cavity. Furthermore, it is extremely difficult for an individual, when brushing, to determine the optimal force required for cleaning. While a user may apply a minimum level of force to enable cleaning, feeling the level at which the force is too high is difficult. In addition, studies have shown that the cleaning ability of a toothbrush may in fact be reduced if brushing force is increased to too high a level.

There are currently brushes on the market which provide feedback to the user regarding the application of too much pressure during brushing. However, without the ability to test these products on shelf, the consumer may purchase one of these available toothbrushes and realize only after the purchase that the feedback provided is insufficient or not desired.

Accordingly, a need exists for a personal hygiene implement which signals to the user when too high a brushing force is being applied which is in packaging which allows the user to test the brush on the store shelf.

As used herein, “oral hygiene implement” refers to any device which can be utilized for the purposes of oral hygiene. Some suitable examples of such devices include toothbrushes (both manual and power), flossers (both manual and power), water picks, and the like.

Description:

For ease of explanation, the oral hygiene implement described hereafter shall be a manual toothbrush; however, as stated above, an oral hygiene implement constructed in accordance with the present invention is not limited to a manual toothbrush construction. Additionally, the packaging embodiments described hereafter are equally applicable to blades, razors, other personal hygiene implements, or the like.

The packaging described herein can allow a consumer to test the visual indication provided by a toothbrush without removal of the toothbrush from the package. For example, for the toothbrushes that provide a visible indication to the user that too much brushing force is being applied, a consumer can trigger the visible indication while the toothbrush is in the package via an application force which simulates a brushing force. The triggering of the visible indication can provide the consumer with some insight as to whether the visible indication is adequate and also provide some insight to the user on the functionality of the toothbrush.

There several types of packaging platforms which can be utilized for the display packages of the present invention. One example is a blister pack. The blister pack comprises a laminated structure which includes an at least partially transparent/translucent blister. The blister is attached to a backer. The blister comprises a cavity which receives the toothbrush such that the toothbrush is positioned between the blister and the backer.

Another example is a clamshell pack. The clamshell pack comprises a laminated structure similar to the blister pack. However, the clamshell pack comprises a front blister which is at least partially transparent and/or translucent and a back blister which may similarly be at least partially transparent and/or translucent. Both the front blister and the back blister have a portion of a cavity such that when combined, the cavity portions form the entire cavity in which the toothbrush resides. Additional packaging platforms are described hereafter.

As shown in FIG. 1A, a display package 100 may comprise a toothbrush 10 and a package body 110. The toothbrush comprises a handle 12, a head 14, and a neck 16 extending between the handle 12 and the head 14. A contact element field 20 extends from a first surface 14A of the head 14. The toothbrush 10 may comprise a distal end 80 and a proximal end 90. A tongue cleaner, soft tissue cleanser, massaging element, or the like, may be disposed on a second surface 14B of the head 14. The contact element field 20, the tongue cleaners, soft tissue cleansers, massaging elements, or the like, are discussed hereafter.

An indication element 30 may be disposed between the handle 12 and the head 14. The indication element 30 may provide a visible signal to a user for at least one of a plurality of conditions. For example, the visible signal may be provided when a user has brushed for an adequate amount of time, e.g. two minutes, when the toothbrush needs to be replaced, and/or when the user is applying too much force when brushing.

The handle 12 may comprise a power supply which is in electrical communication with the indication element 30. A switch may be positioned between the power supply and the indication element 30 such that in a non-use condition, the switch is in a first position which is open such that the indication element 30 is not supplied power from the power supply. In contrast, when a force 199 is applied to the head 14 and/or neck 16 is experienced by the toothbrush 10 exceeds a threshold value, the switch may move to a second position. In the second position, the switch may close thereby allowing power from the power supply to the indication element 30.

The package body 110 which covers the toothbrush 10, at least in part, may be, at least in part, translucent and/or transparent. The package body 110 may comprise a flexible portion 119 and a non-flexible portion(s) 130, 131. As shown, the flexible portion 119 may be disposed between the non-flexible portions 130 (adjacent the distal end 80 of the toothbrush 10) and 131 (adjacent the proximal end 90 of the toothbrush 10).

The package body 110 may comprise a first face 110A and a second face 110B. As shown, the first face 110A and the second face 110B within the location of the flexible portion 119 may each comprise a rugose area 120, 122. The rugose area(s) 120, 122 may facilitate the application of a force to the head 14 and/or neck 16 through the package body 110 to place the switch in the second position thereby energizing the indication element 30. Embodiments are contemplated where the first face 110A comprises the rugose area, e.g. the first rugose area 120 and the second face 110B does not comprise a rugose area. Embodiments are contemplated where the second face 110B comprises the rugose area, e.g. the second rugose area 122 and the first face 110A does not comprise a rugose area. The flexible portion 119 may comprise the rugose area(s) while the non-flexible portions may not comprise rugose area(s).

The placement of the rugose area, the number of ridges in the rugose area depends largely on the position of the brush within the package body 100. For example, if the brush is primarily positioned within a cavity in the first face 110A, then the second face 110B may not require a rugose area. Alternatively, where the brush is primarily positioned within a cavity in the second face 110B, then the first face 110A may not require a rugose area.

As shown in FIG. 1B, the first rugose area 120 may comprise a plurality of ridges 120A, 120B, and 120C. The ridges 120A, 120B, 120C may have adjacent faces which are angled from each other at a first angle 121. The first angle 121 may be about 60 degrees. Any suitable angle may be utilized. For example, the first angle 121 in some embodiments may be between about 0 and about 100 degrees. In some embodiments, the first angle 121 may be greater than about 0 degrees, greater than about 10 degrees, greater than about 15 degrees, greater than about 20 degrees, greater than about 25 degrees, greater than about 30 degrees, greater than about 40 degrees, greater than about 50 degrees, greater than about 60 degrees, greater than about 70 degrees, greater than about 80 degrees, greater than about 90 degrees, less than about 100 degrees, less than about 90 degrees, less than about 80 degrees, less than about 70 degrees, less than about 60 degrees, less than about 50 degrees, less than about 40 degrees, less than about 30 degrees, less than about 20 degrees, less than about 10 degrees, or any number or any range within the values provided.

The second face 110B may comprise the second rugose area 122 which comprises a plurality of ridges 122A and 122B. The ridges 122A and 122B may have adjacent faces which are angled from each other at a second angle 123. The second angle 123 may be less than the first angle 121. In some embodiments, the second angle 123 may be between about 0 degrees to about 100 degrees. The second angle 123 may have the values provided above as described with regard to the first angle 121.

Referring back to the first rugose area 120, the ridges 120A, 120B, and/or 120C, may have a first height 125 of about 2 mm. The first height 125 may be any suitable value. For example, the first height 125 may be between about 0.5 to 10 mm. In some embodiments, the first height 125 may be greater than about 0.5 mm, greater than about 1.0 mm, greater than about 1.5 mm, greater than about 2.0 mm, greater than about 3.0 mm, greater than about 4.0 mm, greater than about 5.0 mm, greater than about 6.0 mm, greater than about 7.0 mm, greater than about 8.0 mm, greater than about 9.0 mm, or less than about 10.0 mm, less than about 9.0 mm, less than about 8.0 mm, less than about 7.0 mm, less than about 6.0 mm, less than about 5.0 mm, less than about 4.0 mm, less than about 3.0 mm, less than about 2.0 mm, less than about 1.0 mm, or any number or range within the values provided.

Regarding the second rugose area 122, the ridges 122A and 122B may have a second height 127 of about 2 mm. The second height 127 may be any suitable value. For example, the second height 127 may be about 0.5 to about 10 mm. The second height 127 may have the same heights as described heretofore with regard to the first height 125.

As shown in FIG. 1B, the first rugose area 120 may comprise more ridges than the second rugose area 122. Additionally, the ridges of the first rugose area 120 may be longitudinally offset from the ridges in the second rugose area 122. As discussed previously, the inclusion of a rugose area may be dependent upon the depth of the cavity in the first face or second face. For those embodiments where the cavity in which the brush is placed is deep, additional ridges may be required to ensure that that portion of the package with the deep cavity has flexibility.

Referring to FIG. 1C, in some embodiments, one or more of the ridges 120A, 120B, 120C may extend in a lateral direction toward lateral edges 190A and 190B of the package body 110. The extension of the ridges 120A, 120B, and/or 120C may provide a visual cue to the consumer that the toothbrush 10 has some flexibility.

Referring to FIGS. 1D and 1E, the ridges 120A, 120B, 120C, may be configured in any suitable manner. For example, the ridges may comprise a triangular shape. In contrast, the ridges 120A, 120B, and/or 120C may comprise a non-standard shape. For example, instead of a narrow tip, the ridges 120A, 120B, and/or 120C may comprise a rounded tip. In some embodiments, the first face 120A and/or the second face 120B may be thermoformed. In such embodiments, the ridges may have a rounded tip. The rounded tip may ensure that during processing the mold over which the plastic is deformed does not punch through the plastic material.

As shown in FIG. 1F, the ridges 120A, 120B, and 120C, may be configured to provide a unique visual effect to the consumer. For example, the ridges 120A, 120B, and/or 120C, may comprise an offset end which is oriented toward the head 14 or toward the handle. As shown, the ridge 120A comprises offset ends 151 positioned on either side of a transverse portion 150. The offset ends 151 may be oriented toward the head 14. Additionally, as shown, the ridge 120C may comprise offset ends 149 positioned on either side of a transverse portion 147. The offset ends 149 may be oriented toward the handle 12. Although not shown, the ridge 120B may comprise an offset end, e.g 149, 151, or a plurality thereof. Additionally, embodiments are contemplated where at least one of the ridges 120A, 120B, and/or 120C comprises a plurality of offset ends which include an offset end 149 and an offset end 151.

Referring now to FIGS. 1A, 1B, and 1F, for those embodiments where the indication element 30 is positioned such that when energized in the display package 100, the indication element 30 provides a visible output through the second face 110B, the ridges 122A and/or 122B in the second rugose area 122 may be configured similar to the ridges 120A, 120B, and/or 120C, discussed above.

As discussed previously, embodiments are contemplated where the first face 110A and/or the second face 110B comprise a rugose area. For those embodiments which utilize a clamshell package platform, the first face 110A and/or the second face 110B may comprise a rugose area. In contrast, for those embodiments which utilize a blister package platform, the first face 110A may have a rugose area, while the second face 110B does not include a rugose area.

As shown in FIG. 2, a display package 200 may comprise a package body 210 and the toothbrush 10. The package body 210 encapsulates, at least in part, the toothbrush 10. The package body 210 includes a first portion 240 and a second portion 250. In between the first portion 240 and the second portion 250, the package body 210 may comprise a plurality of recesses 260 which, in some embodiments, may extend from lateral edge 290A inboard and from lateral edge 290B inboard. The package body 210 may additionally comprise a plurality of light channels 230 which transmit light from the indication element 30. The light channels 230 may extend to lateral edges 290A/290B of the display package 200 from adjacent the indication element 30.

The display package 200 may be configured such that a consumer can grasp the first portion 240 and the second portion 250 and bend either the first portion 240 or the second portion 250 with respect to the other. The bending of the display package 200 can simulate an applied brushing force which exceeds a first threshold thereby placing the switch in the second position, and therefore energizing the indication element 30. In embodiments where the indication element comprises a light source, e.g. LED, the light channels 230 can provide a unique visual perspective to the consumer.

Embodiments are contemplated where the display package 200 comprises light channels 230 on a first face 211A and/or on a second face opposite the first face 211A. For those embodiments where the indication element 30 is limited to providing visual indication through the second face, the light channels 230 on the second face can provide a unique visual effect for the consumer. The display package 200 can be realized by using either the blister package platform or the clamshell platform.

Referring to FIG. 3, a display package 300 may comprise a package body 310 which encapsulates, at least in part, the toothbrush 10 as described heretofore. The package body 310 comprises a first portion 340 and a second portion 350. The first portion 340 may be configured to flex, bend, with respect to the second portion 350. In order to move the switch to the second position, a user can apply a force 399 to the contact element field 20 of the toothbrush 10. Alternatively, or in conjunction with the force 399, a user can apply a force 398 to the neck 16 of the toothbrush 10. When the applied force 399 and/or 398, simulate an applied brushing force which exceeds a first threshold, then the switch is moved to the second position and the indication element 30 becomes energized.

As shown, the package body 310 may further comprise an opening 360 which, at least in part, surrounds the head 14 of the toothbrush 10. The opening 360 extends from a first face 310A through a second face opposite the first face 310A. The package body 310 may further comprise indicia providing visual indication to a consumer as to where the force should be applied that causes the switch to move to the second position. For example, in some embodiments, the package body 310 may comprise indicia adjacent the contact element field 20. In some embodiments, the package body 310 may comprise indicia adjacent the neck 16. In some embodiments, the package body 310 comprises indicia which indicate multiple sites upon which a force could be applied to move the switch to the second position. The display package 300 can be realized by using either the blister package platform or the clamshell platform.

Referring to FIGS. 4A and 4B, a display package 400 has a package body 410 which encapsulates, at least in part, the toothbrush 10. The package body 410 comprises an opening 460 adjacent the head 14, a first portion 450, and a second portion 440. The opening 460 is positioned in the second portion 440. The opening 460 can allow the head 14 and neck 16 pivot with respect to a portion of the package body 410. The handle 12 may be fixed within the package body 410 such that the handle 12 does not rotate with respect to the first portion 450 of the package body 410.

As shown, the package body 410 may comprise a first blister 411, a second blister 412, and an intermediate member 413 positioned between the first blister 411 and the second blister 412. The opening 460 may extend through the intermediate member 413 such that in the opening 460, the first blister 411 and the second blister 412 are joined to each other. Additionally, adjacent a first side 461 of the opening 460, the first blister 411 and/or the second blister 412 may comprise a built in fulcrum allowing the first blister 411 and/or the second blister 412 to bend with respect to the first portion 450.

The display package 400 can be realized by using either the blister package platform or the clamshell platform. However, with regard to the blister package platform, it is important to note that as shown in FIG. 4B, the first blister 411 and the second blister 412 may form a first surface 410A and a second surface 410B, opposite the first surface 410A, of the package body 410. In contrast, the backer, as described previously for the blister package platform, typically forms the equivalent of the second surface 410A.

In another embodiment, an opening may be positioned differently than shown in FIGS. 4A and 4B. As shown in FIGS. 5A and 5B, a display package 500 comprises a package body 510 that at least partially encapsulates the toothbrush 10. The package body 510 may comprise an opening 560 that is positioned near the indication element 30 of the toothbrush 10. The package body 510 has a first portion 550 and a second portion 540. The package body 510 may further comprise a first blister 510A, a second blister 510B, and a backer 520.

As shown, in the first portion 550, the backer 520 may form at least a portion of a front surface 511A which covers the handle 12 of the toothbrush 10. Opposite the front surface 511A, a back surface 511B may be formed by a first blister 510A. Between the first portion 550 and the second portion 540, the package body 510 may transition such that the front surface 511A, adjacent the opening 560, declines toward the back surface 511B. In doing so, a portion of the toothbrush 10 becomes visible to the consumer when viewing the front surface 511A.

In the second section 540, the front surface 511A may be formed by the backer 520 and by a second blister 510B. The decline of the first surface 511A toward the second surface 511B can allow the second portion 540 to bend with respect to the first portion 550, thereby allowing the consumer to move the switch to the second position to illuminate the indication element 30 within the package body 510.

In such embodiments, an application indicator 570 may be placed on the second blister 510B adjacent the contact elements 20. The application indicator 570 may provide visual indication to the consumer as to where the application of force should occur on the package body 510 in order to energize the indication element 30. In some embodiments, an application indicator may be placed adjacent the neck 16. In some embodiments, a plurality of application indicators may be provided. For example, the application indicator 570 as described above may be provided, and additionally, an application indicator positioned adjacent the neck 16 may be provided.

The display package 500 can be realized by using the blister package platform. The package can comprise rugose areas.

As shown in FIG. 6, a display package 600 may comprise a package body 610 which encapsulates, at least in part, the toothbrush 10. As shown, the package body 610 may comprise a plurality of openings 660A and 660B which are positioned on either side of the toothbrush 10 adjacent the indication element 30. The display package 600 can be realized by using either the blister package platform or the clamshell platform.

For those embodiments utilizing the blister pack platform, the openings 660A and 660B may extend through the blister and/or the backer. For those embodiments utilizing the clamshell pack platform, the openings 660A and 660B may extend through the first blister and/or the second blister.

The openings 660A and 660B may allow a second portion 640 of the package body 610 to bend with regard to a first portion 650 of the package body 610. Additionally, the openings 660A and 660B can provide visual indication to the consumer that the display package 600, including the package body 610 and the toothbrush 10 are flexible in nature.

The openings 660A and 660B may comprise any suitable shape. For example, as shown, the openings 660A and 660B may comprise zig-zags, circles, squares, rectangles, polygons, the like, and combinations thereof, which are either discrete or a plurality of such openings could be joined together to collectively form an opening.

As shown in FIG. 7, a display package 700 comprises a package body 710 encapsulating, at least in part, the toothbrush 10. The package body 710 may comprise a plurality of openings 760A and 760B which are positioned adjacent the indication element 30.
