Abstract
The invention relates to a system for dispensing face masks. The system includes a stack of masks arranged within an interior of a container. The container has a dispensing opening therein for the withdrawal of a single or a specific plurality of masks. The ties of the masks within the stack are arranged so that they extend along the interior walls of the container and rest upon the furthest surface of the mask furthest away from the dispensing opening.
Description




BACKGROUND




The invention relates to face mask dispensers. Current face masks are typically dispensed from the top of an opened container. Due at least in part to the manner in which the masks are loaded into the dispenser the face mask ties often become entangled. Typically this results in the dispense of numerous masks when only one was intended. Often times the dispensing of multiple masks results in product waste and time delay. In the case of surgical masks, where sterility is at issue, removal of each mask from the dispenser potentially contaminates the mask and makes it unsuitable for use in surgery. Therefore when multiple masks are inadvertently dispensed, the additional masks being at risk of contamination should not be returned to the dispenser. Moreover, untangling the ties of individual masks from one another could result in valuable time wasted in a surgical setting. Additionally, since the masks are normally dispensed from the top of an open container, the top mask is often exposed to the environment each time the box is opened.




As such, what is needed is a face mask dispenser that can dependably and easily dispense the required number of face masks from a dispenser thereby minimizing the risk of exposing inadvertently disposed face masks to contamination. Additionally, it is desirable to minimize contamination of the stack of masks remaining within the interior of the dispenser as well.




SUMMARY OF THE INVENTION




As such, one aspect of the present invention discloses a dispensing system for individual planar shaped face masks from a stack of such masks. The dispensing system may include a container having a top, a bottom, and a plurality of walls that define an interior space. Additionally, a plurality of individual planar shaped face masks are included. Each mask may have a shape retaining element for conforming the mask to a user's face and a plurality of ties for securing the mask to the user's face. Each mask may be arranged in stacked relation with respect to an adjacent mask with the ties from substantially all of the masks disposed upon an uppermost surface of an uppermost mask in the stack. The container may have a dispensing opening having a length, a height, and a widened region defined in a lowermost portion of one of the plurality of walls. The length of the dispensing opening substantially corresponds to the length of the face mask and the height substantially corresponds to the thickness of the face mask. The plurality of face masks may be positioned so that the shape retaining element of each face mask is disposed proximal to the wall having the dispensing opening. A bottommost face mask of the stack is substantially aligned with the dispensing opening in a dispensing position and the widened region provides a location for the user to grip the bottommost mask proximal to the shape retaining element for extraction from the interior space of the container.




Another aspect of the present invention provides a dispensing system for dispensing individual face masks from a stack of such masks. The system includes a plurality of flat, rectangular, face masks each having a thickness, a length, and a width. Each mask has a shape retaining element and a flexible tie extending from each corner of the mask. The plurality of masks are arranged in stacked relation with the shape retaining element of each mask superposed with that of an adjacent mask and the flexible ties from each comer of each mask are generally mingled with the flexible ties from corresponding comers of the masks in the stack. The system also includes a container for storing and dispensing the plurality of masks. The container has a top, a bottom, a front wall, a back wall, and side walls that in combination define an interior space. The front wall may include a dispensing opening located at a bottommost portion of the front wall proximal to the bottom wall. The dispensing opening may have a length that corresponds about to the length of an individual mask, may have a height that corresponds about to the thickness of an individual mask, and may have a larger open region intersecting with the dispenser opening. The stack of masks are loaded into the interior space of the container so that the shape retaining element is disposed proximal the front wall such that the plurality of ties extend generally in an upward direction along the walls of the container from the bottom of the container toward the top of the container and at least partially rest upon an uppermost surface of the uppermost mask in the stack. The larger open region provides access to the bottommost mask for withdrawal from the interior of the container.




Another aspect of the present invention provides a dispensing system for dispensing face masks from a stack of such masks. The system includes a plurality of flat face masks each having a first and second surface, a thickness, a length, a width, and a plurality of flexible ties extending therefrom. The plurality of masks are arranged in stacked relation with the flexible ties of each mask generally mingled with the flexible ties of other masks in the stack. The system also includes a container for storing and dispensing the plurality of masks. The container has a plurality of walls defining an interior space and a dispensing opening located in at least one of the walls for dispensing face masks from the interior space. The dispensing opening has a length corresponding about to the length of the mask and a height corresponding about to the thickness of at least one mask. The stack of masks are loaded into the interior space of the container with the plurality of ties extending generally perpendicular to at least one mask surface, away from the dispenser opening and at least partially adjacent to at least one wall within the interior space.

DESCRIPTION OF THE INVENTION




The present invention and its advantages are best understood by referring to the drawings, like numerals being used for like and corresponding parts of the various drawings.




With reference to

FIG. 1

, the present invention provides a dispensing system


10


for dispensing face masks


12


from a container


14


. In certain embodiments such as that shown in

FIG. 2

, the face masks


12


may be flat and rectangular in profile. Each face mask


12


may have a length “L


1


”, a width “W


1


”, and a thickness “T


1


” (as depicted on FIG.


4


). Additionally, each face mask


12


comprises a first surface


16


and a second surface


18


. One of the two surfaces


16


,


18


is intended to be placed against a user's face and is to be referred to as an inner surface


20


. Likewise the remaining surface is to be referred to as an outer surface


22


and is intended to face away from the user toward the environment.




Additionally some manner for securing the face mask


12


to the user's face should be provided. In certain embodiments, a plurality of flexible ties


24


may be provided to perform this function. These ties


24


may be attached to the face mask


12


in any number of fashions including but not limited to adhesive, ultrasonic bonding, thermal bonding, and/or stitching. The ties


24


may be formed into the face mask


12


itself and/or may be threaded through suitable pathways contained in the face mask


12


(not shown).




In certain embodiments, such as shown in

FIG. 2

, these ties


24


may be attached to the face mask


12


such that ends


26


extend from the face mask


12


. Other embodiments envision attaching the tie


24


to the face mask


12


by one end


26


enabling the other end


26


to extend from the face mask


12


. Looking still to

FIG. 2

, it may be seen that in one embodiment the face mask


12


is generally rectangular in shape having corners


28


and opposing edges


30


and


32


. In such an embodiment the ties


24


may be positioned such that at least a portion of a tie


24


extends from each corner of the face mask


12


. The ties


24


themselves may be, for example, attached to opposing edges


30


of the face mask


12


.




In certain embodiments, the face mask


12


comprises a shape retaining element


34


for conforming the mask to the user's nose. The shape retaining element


34


may be a conformable wire, strip of metal, or some other element capable of being bent into a shape and generally able to retain that shape. Many versions of shape retaining elements for face masks are known by and available to those skilled in the art.




Looking now to

FIG. 3

, one example of the container


14


is shown. In this particular embodiment it can be seen that the container


14


comprises a plurality of walls which define an interior space


36


. The walls may include a top


38


, a bottom


40


, a front


42


, a back


44


, and side walls


46


. The container


14


may be made of a variety of materials. Some embodiments may include cardboard, paperboard, plastics, metals, as well as other rigid and semi-rigid materials. One possible embodiment as depicted in

FIG. 3

contemplates that the container


14


be disposable once the face mask supply is exhausted and therefore a stiff paperboard container would be suitable for this purpose. Other embodiments, not shown, may include permanent containers, including for example wall mounted units.




Looking still to

FIG. 3

, a dispensing opening


48


is provided in at least one of the walls of the container


14


. In some embodiments the dispensing opening


48


is provided in the front


42


proximal to the top


38


or bottom


40


. The dispensing opening


48


enables a user to access and remove at least one of the face masks


12


contained within the interior space


36


. The dispensing opening


48


has a length “L


2


” and a height “H


2


”. In many embodiments, the length “L


2


” of the opening


42


corresponds generally to the length “L


1


” of any one of the face masks


12


. The height “H


2


” may generally correspond to the thickness “T


1


” of at least one of the face masks


12


. However, in the event the container


14


is designed to dispense a plurality of masks


12


simultaneously, the height “H


2


” would be sized accordingly as understood by those skilled in the art.




Some embodiments of container


14


comprise a widened region or larger open region


50


that partially or fully overlaps some portion of the dispensing opening


48


. In some embodiments, this region


50


may be centered horizontally, vertically, or both on the dispensing opening


48


. However, it may be positioned in any other fashion desired so that it partially or fully overlaps any portion of the dispensing opening


48


. Moreover a plurality of such regions


50


may be provided. One possible advantage provided by the addition of region or regions


50


is to enable a user to have easier access to a face mask or face masks within the container


14


.




Turning to

FIG. 4

it may be seen that the face masks


12


are arranged in-a stacked, aligned relation superposed one upon another to form stack


52


. In some arrangements, stacking of the masks


12


may be accomplished by orienting the inner surface


20


of each mask in the same direction so that the inner surface


20


of one mask


12


is in contact with the outer surface


22


of the next mask


12


. Further, some configurations provide that the masks


12


are arranged such that the shape retaining member


34


of each mask


12


is also stacked and superposed one upon another.




As can be seen in

FIG. 4

the flexible ties


24


of each mask


12


are generally allowed to mingle with one another upon formation of the stack


52


. The stack


52


may subsequently be loaded into the interior space


36


of the container


14


so that the plurality of ties


24


extend generally, for example, in an upward direction along the walls of the container


14


from the bottom


40


of the container


14


toward the top


38


of the container


14


and at least partially rest upon an uppermost surface of the uppermost mask


12


in the stack


52


. It would be understood by those skilled in the art that the direction in which the ties


24


lie is dependent upon how the masks


14


are loaded into the container


14


. In any event, in one embodiment, the plurality of ties


24


extend along the walls of the container


14


so that ends


26


lie upon the furthest surface


20


or


22


of the furthest mask


12


from the dispensing opening


48


.




Other embodiments contemplate a plurality of groups of stacked masks


12


. Each of these groups may subsequently assembled into the stack


52


. In this embodiment, the ties


24


of each group are placed so that the ends


26


of those ties


24


lie upon one surface


20


or


22


of one of the endmost masks


12


in the group. Therefore when the groups are formed into the stack


52


, some plurality of the ends


26


will be situated between masks


12


and others will be situated upon the furthest surface


20


or


22


of the furthest mask


12


from the dispensing opening


48


.




In some embodiments, the stack is oriented so that the shape retaining element


34


is disposed proximal the front wall


42


. In this embodiment, the dispensing opening


48


may also be on the front wall


42


. This configuration enables the user to grasp a face mask


12


by the shape retaining element


34


. An advantage to this configuration is that as the face mask


12


is withdrawn from the container


14


, the shape retaining element


34


is partially preshaped to fit the user's face during the extraction of the mask


12


from the dispenser


14


. As such the dispensing and first step of donning the face mask


12


are concurrent. Regardless of the manner in which the masks


12


are stacked within the container


14


, the dispensing opening


48


minimizes the exposure of the mask surfaces


20


and


22


to air contamination.




Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions, and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
