BACKGROUND OF THE DISCLOSURE
1. Field of the Disclosure
The present disclosure relates to food storage. Particularly, the present disclosure relates to a food storage container having a bowl that connects to a lid and provides at least one of an audible, visual, and tactile indication to a user that the lid is properly sealed or attached to the bowl.
2. Description of the Related Art
Care for children requires transport and storage of food. Food containers may have a bowl with an opening to insert food for storage in the bowl, which opening is then closed or covered by a lid. Current food containers in the market are not able to indicate to a user if the food container has been properly sealed and, thus, is free from spilling once the lid is closed. Unwanted spills and leaks occur during transportation or when the bowl accidentally falls sideways during storage.
Accordingly, there is a need for a storage container, preferably ergonomic, that provides a user with at least one of an audible, visual, and tactile signal when the food storage container is securely sealed, which makes for a practical and secure food storage container that can be used on the go or at home.
SUMMARY OF THE DISCLOSURE
There is provided a food storage container that has a bowl and a lid that connects to the bowl when in a sealed or closed position. Upon movement of the bowl and lid into the closed position, at least one of an audible, visual, and tactile signal is generated, indicating to the user that the lid is securely and properly sealed onto the bowl.
The above-described and other features and advantages of the present disclosure will be appreciated and understood by those skilled in the art from the following detailed description, drawings, and appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings and, in particular, FIG. 1, an exemplary embodiment of a bowl 100 connected to a lid 200 according to the present disclosure is shown. Bowl 100 has a bowl wall 102. Bowl wall 102 has a convex shape, or chamfered hemisphere, to form, as shown in FIG. 2, an interior volume 104. Bowl 100 and lid 200, for example, are each made of plastic, such as polypropylene.
Referring to FIG. 2, bowl wall 102 has an inner surface 106 facing interior volume 104 and, as shown in FIG. 1, an outer surface 108 opposite interior volume 104. Bowl wall 102 has a bottom portion 110 that has a thickness greater than a middle portion 112 so that bottom portion 110 protrudes from middle portion 112. Bottom portion 110 may have a shape of a wave 114. Inner surface 106 is smooth. Inner surface 106 (not shown on FIG. 1) has a smooth curve 152 (not shown on FIG. 1) forming dome shape portion 150. Outer surface 108 has an indicator 116. Indicator 116, for example, has a shape of a triangle or arrowhead protruding from bowl wall 102.
Bowl wall 102 forms a rim 118 that is perpendicular to middle portion 112 of bowl wall 102. Rim 118 has a tongue 120 that protrudes from a remainder of rim 118. Tongue 120 bends downward toward bottom portion 110. Tongue 120 has a top surface 122 and a bottom surface 124, as shown in FIG. 3.
Referring to FIG. 1, tongue 120 has a connector 126. Connector 126 has a tab 128 that is cantilevered within an aperture 130 through tongue 120. Tab 128 has a first side 132 that connects to tongue 120 and a second side 134 opposite first side 132 that is free. Tab 128 has a top surface 136 and, as shown in FIG. 9, a bottom surface 138. Top surface 136 has a ramp 140 that protrudes therefrom.
Lid 200 has lid wall 202. Lid wall 202 has a top wall 204 and a side wall 206 that forms a curve with top wall 204 so that it is perpendicular thereto. Top wall 204 has an indentation 208. Indentation 208 has, for example, a circular shape that is sized complimentary to bottom of bowl 100 to align with another bowl having the same shape as bowl 100 to allow stacking of bowls when lid 200 is connected to bowl 100. Middle portion 208a may have a disk like window (not shown) that is hinged to middle portion 208a. The disk is imbedded within lid wall 202 when closed without causing a surface that protrudes outwards. The disk like window protects a label that can be inserted therein.
As shown in FIG. 1, side wall 206 has an exterior surface 212 and an interior surface 210 opposite exterior surface 212, as shown in FIG. 6. Referring to FIG. 6, exterior surface 212 has grippers 214 that protrude from lid wall 202. Grippers 214 facilitate gripping for moving or rotating lid 200 by hands of a user. Side wall 206 has an edge 216 between interior surface 210 and exterior surface 212. Protrusions 218 protrude from edge 216. Protrusions 218 have a shape, for example, of a hemisphere. Each protrusion 218 may have a triangle or arrowhead 217 that protrudes from exterior surface 212. The arrowhead has an apex that is in protrusion 218.
Referring to FIG. 3, bowl wall 102 has a top portion 142 on a side of rim 118 opposite middle portion 112. Top portion 142 has bowl threads 144 on outer surface 108. Each bowl thread 144 slants from a top edge 146 towards rim 118 and has a stop 148 at an end of each thread 144 closest to rim 118. Stop 148 is a protrusion that extends from thread 144 towards rim 118. Bowl wall 102 has a dome shape portion 150 to rest bowl 100 on a surface.
Referring to FIG. 4, connector 126 has tab 128 that is cantilevered within aperture 130 through tongue 120. Aperture 130 is U-shaped. Tab 128 has first side 132 that connects to tongue 120 and second side 134 opposite first side 132 that is free. Tab 128 has top surface 136 that has ramp 140 that protrudes therefrom. Tab 128 has a third side 154 and a fourth side 156 opposite third side 154. Ramp 140 increases in height, as measured from top surface 136 of tab 128 to a top surface 155 of ramp 140, from fourth side 156 to third side 154.
Referring to FIG. 5, top wall 204 forms a curved portion 220 with side wall 206. Edge 216 may have four protrusions 218 spaced around a circumference thereof.
Referring to FIG. 6, interior surface 210 of lid 200 has lid threads 222. Lid threads 222 protrude from interior surface 210. Lid threads 222 are straight and slightly slanted towards edge 216. Lid 200 has an inner wall 224 parallel to side wall 206 having a space 226 therebetween.
Referring to FIGS. 7-10, to connect lid 200 to bowl 100, a user aligns any one of protrusions 218 with indicator 116. By aligning one protrusion 218 with indicator 116, each lid thread 222 is between two adjacent bowl threads 144, and lid threads 222 are spaced away from bowl threads 144 so that lid 200 may be moved toward bowl 100 until protrusions 218 abut rim 118. Lid 200 may then be rotated. If lid is rotated in a first direction 302, counterclockwise as shown in FIGS. 1-11, each lid thread 222 will abut one stop 148 and further rotation of lid 200 will be prevented. If lid 200 is rotated in a second direction 304, clockwise as shown in FIGS. 1-11, each lid thread 222 will pass under bowl threads 144 so that bowl threads 144 are each between one lid thread 222 and top wall 204. During rotation in second direction 304, one protrusion 218a interferes with ramp 140. The protrusion 218a moves over ramp 140 from a smaller height 140a of ramp 140 on fourth side 156 to a larger height 140b of the ramp on third side 154, as shown by dashed line 157 in FIG. 7. Bowl threads 144 apply a force to lid 200 so that once protrusion 218a has passed over ramp 140, as shown in the solid lines of FIG. 7, lid 200 contacts or “strikes” bowl 100 with such force that an audible sound or “click” is generated. Once protrusion 218a has passed over ramp 140, each lid thread 244 also abuts one stop 148. Tab 128 may also be a resilient material so that the protrusion 218a deflects tab 128 from an initial position moving ramp 140 away from lid 200 through aperture 130. Once protrusion 218a has passed over ramp 140, the resilient material of tab 128 rebounds back to the initial position. The larger height 140b of ramp 140 and stops 148 maintain the protrusion 218a in place adjacent ramp 140, and bowl threads 144 maintain lid 200 connected to bowl 100, as shown in FIG. 7, in a closed position.
Referring to FIG. 11, when lid 200 is connected to bowl 100, inner wall 224 abuts inner surface 106 to seal interior volume 104.
When bowl 100 and lid 200 are in the closed position, as shown in FIG. 7, lid 200 can be disconnected from bowl 100 by rotating lid 200 in first direction 302 so that protrusion 218a passes over ramp 140 and either one protrusion 218 aligns with indicator 116 or each lid thread 222 abuts one stop 148 preventing further rotation of lid 200. When one protrusion 218 aligns with indicator 116 or each lid thread 222 abuts one stop 148, each lid thread 222 is between two adjacent bowl threads 144, and lid threads 222 are spaced away from bowl threads 144 so that lid 200 may be moved away from bowl 100 to disconnect lid 200 from bowl 100.
Bowl 100 and lid 200 are ergonomic. Significantly, an audible sound or signal is given when lid 200 is securely connected to bowl 100. This audible sound or signal makes for a practical indicator to the user that the food storage container is securely closed. Clearly, this feature is valuable for the user on the go or at home. Bowl 100 and lid 200 keep food securely contained in interior volume 104 without unwanted spillage. Bowl 100 and lid 200, in comparison to current food storage containers, improves the way food or snacks are transported, and improves the way they are stored at home, by the audible cue and also the visual and tactile indications that the lid is properly closed so that the bowl is sealed. Bowl 100 and lid 200 solve the problem of the unknown improper closure that results in the unwanted spills and leaks during transportation or when the bowl accidentally falls sideways during refrigerator storage.
It should also be recognized that the terms “first”, “second”, “third”, “upper”, “lower”, and the like may be used herein to modify various elements. These modifiers do not imply a spatial, sequential, or hierarchical order to the modified elements unless specifically stated.
While the present disclosure has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the scope thereof.
