BACKGROUND OF THE INVENTION

Field of the Invention

The invention relates generally to assistive devices for opening shopping bags, and more particularly to sanitary assistive devices worn on a user's finger for opening thin plastic shopping bags. Separating adjacent walls of plastic bags is a struggle for most people. The plastic bag walls are very thin and tend to stick together making it difficult for a user to obtain access to the inside of the bag. This leaves many shoppers frustrated. Some shoppers lick their fingers in an attempt to assist separation. This is very unsanitary and contributes to the spreading of germs.

Description of Related Art

Various forms of fingertip covers are available in the prior art. Most of these are manufactured from a rubber or silicone rubber and attempt to utilize small elastomeric projections from the surface to improve frictional capabilities for separating the back. This rarely works well. What is needed is a more effective bag wall separation device and a device that helps reduce the spreading of germs.

Select embodiments of the invention will now be described with reference to the Figures. Like numerals indicate like or corresponding elements throughout the several views and wherein various embodiments are separated by letters (i.e. 100, 100B, 100C). The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive way, simply because it is being utilized in conjunction with detailed description of certain specific embodiments of the invention. Furthermore, embodiments of the invention may include several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the invention described herein.
FIG. 1-5 depict views of a preferred embodiment of a novel sanitary assistive device. FIGS. 1-2 are perspective views, FIG. 3 is a side view, and FIGS. 4-7, 9 are cross-sectional views through central plane F. FIGS. 4, 6, 7 illustrates the sanitary assistive device 100 that includes tack 138 whereas FIG. 5 illustrates the device with tack 138 removed.
The sanitary assistive device 100 is worn on a user's finger as illustrated in FIG. 10 , to assist with opening thin plastic bags and as a sanitary barrier. In this embodiment, the sanitary assistive device 100 comprises an elongate tube body 114. The elongate tube body 114 comprises a proximal port axis (Axis A) extending centrally along the elongate tube body 114. On a distal end, the elongate tube body is enclosed by a distal wall 115 whereas a tube wall 118 forms the elongate tube body and has an inner face 120 formed thereon facing interior. Although it may assume other profiles such as polygons such as a hexagon, the inner face 120 in this embodiment is generally cylindrical and defines a finger space 122 sized for housing a user's finger. An outer face 124 is formed on the tube wall 118 and faces the exterior.
The elongate tube body 114 comprises a proximal face 126 at a proximal end and which extends between the inner face 120 and the outer face 124. A proximal port 128 extends through the proximal face 126 to provide entry for a user's finger to reside in finger space 122 from a proximal end. As illustrated here, a distal face 117 is formed on the distal wall 115 and faces distally, whereas, an end face 116 is formed on the distal wall 115 and faces proximally. A joint face 130 extends laterally partially through the elongate tube body 114 and again extends between the inner face 120 and outer face 124. The joint face 130 defines a joint port 132 laterally extending through a side of the elongate tube body 114. The joint port 132 is spaced towards a proximal end of the elongate tube body and is formed to accommodate an enlarged DIP joint as it rises during bending.
A tack face 134 (FIG. 5 ) defines a tack port 136 extending through a side of the elongate tube body between the inner face 120 and outer face 124. In preferred forms, the tack port 136 and the joint port 132 are positioned substantially on opposed sides of the elongate tube body 114. As illustrated in the Figures, the tack port 136 is spaced towards a distal end of the elongate tube body with the tack face 134 extending between the inner face 120 and outer face 124 of the elongate tube body. The tack port 136 comprises a central tack port axis (axis B) that is substantially perpendicular to the proximal port axis.
In some embodiments, the finger space 122 comprises a diameter smaller than a user's finger and can be stretched over a larger diameter thereby providing a frictional fit over the end of the finger. The elongate tube body is made from an elastomeric material such as a silicone.
A tack 138 comprising a T-shaped body 140 is housed in the tack port 136 in an assembled configuration. The T-shaped body 140 comprises an enlarged head 142. The enlarged head and stem in this embodiment are rounded as if turned on a lathe. Here, the enlarged head 142 is substantially flat. Tactile surface 146 is formed on the top of the enlarged head 142 and is opposed by a stop surface 146 on the opposing side of the enlarged head 142. The tactile surface is positioned in the assembled configuration to abut the user's finger pad of their distal phalange 104. The T-shaped body 140 comprises a stem 148 extending from the enlarged head 142. The stem 148 comprises an annular recess 150. The profile of the stem 148 complements the profile of the tack port 136 such that the stem can be pressed and seated therein. When seated in the tack port 136, the protruding tack port ridge 135 is seated within the annular recess 150 thereby retaining the tack 138 in the in the tack port. The T-shaped body 140 comprises a tip 152. As illustrated, the tip 152 extends beyond the outer face 124 of the elongate tube body 114 a distance E in an assembled configuration. This distance is just enough for the tip 152 to catch on one layer of a plastic bag when dragged across its surface. The tack is preferably made from a rigid material such as a polymer, or metal. Vibrations through the tack are transmitted to the user's finger pad of their distal phalange providing the user a sensitive sense of touch despite wearing the assistive device. The tack can also be used to perform tasks such as pressing buttons on a keypad.
As illustrated in the Figures, a tack flap 154 extends from the outer face 124 of the elongate tube body 114 from a position proximally adjacent the tack port 136. The tack flap 154 comprises a cover face 156 facing the outer face 124 and an exterior face 158 opposing the cover face 156. The tack flap 154 is biased whereby the cover face 156 covers the tip 152 of the tack 138 in a covered configuration. A user exposes the tip 152 of the tack 138 by retracting the tack flap 154 proximally in a retracted configuration. This is done for example, by rubbing the user's thumb proximately over the tack flap such that the tack flap moves from the position illustrated in FIG. 6 to the position illustrated in FIG. 7 .
A method of separating thin plastic bags utilizing a the novel sanitary assistive device described herein comprises the following steps (FIG. 11 ). Obtaining a sanitary assistive device as described in the previous paragraphs that includes an elongate tube body, a proximal port leading into a finger space, a joint port, a tack port with a T-shaped tack housed therein, and a tack flap extending over the tack port from an outer face of the elongate tube body (170). Sliding a user's finger through the proximal port such that it is fully seated in a finger space whereby the user's finger pad of their distal phalange is resting on a tactile surface of a tack housed in a finger port of the sanitary assistive device (172). Obtaining a thin plastic bag (174). Retract the tack flap, for example by placing the user's thumb over the tack flap retracting the tack flap proximally thereby exposing the tip of the tack (176). Placing the tip of the tack on an outer surface of the thin plastic bag and dragging such that the sides of the thin plastic bag separate to provide access to the inside of the bag (178).
