Food Storage Unit

Abstract

A food storage unit provides a container and a cover which use an interference fit to snap the cover onto the container. The two engage with each other by a first lip (of the container) and a second lip (of the cover). The lips are configured to have an obtuse angle of 95 degrees, helping to create a better fit between the two. The second lip deforms when placed over the first lip; the resulting pressure and friction helps to seal the cover to the container. To help create a more secure attachment, a latching member is connected to the second lip. The latching member is positioned just below the first lip, such that the cover cannot be lifted straight up until a person manually moves the latching member away from the first lip. This helps prevent the cover from accidentally coming loose from the container.

Description

The current application claims a priority to the U.S. Provisional Patent application Ser. No. 62/239,074 filed on Oct. 8, 2015.

FIELD OF THE INVENTION

The present invention relates to storage containers. In particular, the present invention relates to a food container and cover with specifically angled lip components which prevent the cover from coming loose and detaching in unwanted circumstances.

BACKGROUND OF THE INVENTION

Food containers are devices used for the storage and transportation of food. These objects often incorporate the use of lids which attach over the top of the container in order to cover and preserve contents of the container for longer periods of time. The lid also serves to inhibit the buildup of harmful bacteria and prevent unwanted leakage. Tupperware (a colloquial name for food storage containers) and devices alike are often made of microwaveable plastic and commonly use various lip designs which allow lids to snap onto corresponding containers. Problems exist, however, as the lids often come loose and detach during unwanted circumstances. Most noticeably, this occurs during transportation, when containers are knocked around or when being heated up in microwaves, as the increase in temperature leads to material expansion and deformation.

It is therefore an objective of the present invention to introduce a new food container and lid device. The present invention includes uniquely shaped container and cover lips which snap together, but will not come loose due to various outwards sloping angles. The present invention is stackable, allowing multiple containers to be seated on top of each other, with tight snap-on covers (lids). The cover and container lips utilize stronger and thicker edges compared to other inventions, especially at the bottom where the cover locks in. Unlike other devices, the cover will not snap off when the container is heated up. Overall, the present invention is sturdy, safe, reliable, practical, and suited for mass production.

DETAIL DESCRIPTIONS OF THE INVENTION

All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

The present invention is a food storage unit that includes a food container 1 and cover 2. The present invention is uniquely shaped, such that the container 1 and cover 2 easily snap together in a secure fashion. Thanks to the angles and slopes of several components, the container 1 and cover 2 remain secured to each other, once attached. They do not accidentally loosen from each other during normal use. Of course a user can still easily separate the container 1 and cover 2 when desired by disengaging certain components of the container 1 and the cover 2. Further, the present invention is constructed to be stackable, allowing multiple containers (with attached covers 2) to be positioned atop each other into a vertical stack. It is noted that while the present invention is primarily intended to be used for the purpose of storing and transporting food or similar contents, the present invention may be utilized in other settings, situations, and scenarios. The container 1 is illustrated in FIG. 1-FIG. 3, the cover 2 in FIG. 4-FIG. 6, and their attachment via FIG. 7.

The present invention is a food receptacle with lid. The present invention comprises a container 1 and a cover 2. The cover 2 can be attached to the container 1 to create an enclosed region with the container 1. The container 1 comprises a base 11, a first lateral body 12, and a first lip 13. The cover 2 comprises a top surface 21, a second lateral body 22, and a second lip 23. The second lip 23 interfaces with the first lip 13 in a manner that supports attachment of the cover 2 to the container 1. Effectively, a snap connection allows the first lip 13 to interface with the second lip 23, resulting in attachment of the cover 2 to the container 1.

The basic operating principle of the present invention is the flexing of the cover 2 (more specifically the second lip 23) to fit to the container 1 (more specifically the first lip 13). When the cover 2 is attached atop the container 1, the sides of the cover 2 flex to match the contour of the container 1. This results in an interference fit (i.e. the snap connection earlier reference) between the cover 2 and container 1, which securely engages the cover 2 to the container 1 during storage and transport.

Further defining the container 1, the first lip 13 is perimetrically connected to the first lateral body 12. The first lateral body 12 itself is perimetrically connected to the base 11; this creates the basic structure of the container 1, allowing for items to be placed atop the base 11 within the first lateral body 12. The region bounded by the first lateral body 12 and the base 11 is a receptacle for contents, for example food or other items.

The first lip 13 allows the container 1 to receive a matching part from the cover 2 (i.e. the second lip 23) in order to secure the cover 2 to the container 1. Thus, the first lip 13 is preferably positioned at an upper end of the first lateral body 12. The base 11, conversely, is positioned at a lower end of the first lateral body 12. In short, the base 11 and the first lip 13 are positioned opposite each other across the first lateral body 12.

The first lip 13 itself comprises a channel 14, a first inner wall 15, a first outer wall 16, and a first ridge 17. The channel 14 is positioned adjacent to the first lateral body 12. The channel 14 is delineated by the first lateral body 12, a floor 18, and the first inner wall 15. The channel 14 serves as a receptacle for a corresponding component of the second lip 23, as later described.

As mentioned, the floor 18 and the first inner wall 15 delineate a part of the channel 14. The floor 18 is adjacently connected to the first lateral body 12. The first inner wall 16 is adjacently connected to the floor 18, opposite the first lateral body 12. Connected adjacent to the first inner wall 15, at a top edge, is the first ridge 17. The first ridge 17 is thus positioned opposite the floor 18 along the first inner wall 15. Further, the first ridge 17 is orientated away from the first inner wall 15, such that it protrudes away from the first inner wall 16 and first lateral body 12. Restated, the first ridge 17 is positioned adjacent to the first inner wall 15, opposite the floor 18. The first outer wall 16 is adjacently connected to the first ridge 17. The second outer wall 16 is positioned at the outermost area of the container 1; effectively, the first ridge 17 is connected between the first inner wall 15 and the first outer wall 16.

The above describes a basic configuration of components for the container 1 of the present invention. Different embodiments may be derived from this core setup, as later described.

Addressing the cover 2, the second lip 23 is adjacently and perimetrically connected around the second lateral body 22. The second lateral body 22 is likewise adjacently and perimetrically connected around the top surface 21. This results in the basic configuration for the cover 2. The top surface 21 serves to completely enclose an interior volume of a container 1 (when the cover 2 and the container 1 are in an attached configuration) while the second lip 23 enables attachment of the cover 2 to the container 1.

The second lip 23 is very similar to the first lip 13, in that the second lip 23 comprises a second inner wall 25, a second ridge 27, and a second outer wall 26. The second lip 23 also comprises a sealing insert 24, which interfaces with the channel 14 of the first lip 13. The sealing insert 24 is adjacently connected to the second lateral body 22. The sealing insert 24 is positioned exterior to the second lateral body 22, and just below a bottom edge of the second lateral body 22. In short, the sealing insert 24 is contoured to fit into the channel 14 of the first lip 13, allowing for the cover 2 to attach to the container 1.

The second inner wall 25 is adjacently connected to the sealing insert 24, opposite the second lateral body 22. Resultantly, the sealing insert 24 is positioned between the second lateral body 22 and the second inner wall 25. Paralleling the first lip 13, the second ridge 27 serves as a rim that connects the second outer wall 26 to the second inner wall 25. The second ridge 27 is adjacently connected to an upper edge of the second inner wall 25, opposite the sealing insert 24. The second outer wall 26 is offset from the second inner wall 25, the latter separated from the former by the second ridge 27. Thus, the second outer wall 26 is adjacently connected to the second ridge 27, at an end opposite the second inner wall 25.

In addition to the above components, the second lip 23 further comprises a latching member 28. This latching member 28 is adjacently connected to a bottom edge of the second outer wall 26. The latching member 28 presses against the first outer wall 15 of the container 1 to lock the cover 2 to the container 1, as later described.

The above describes a basic configuration of components for the cover 2 of the present invention. In combination with the basic configuration for the container 1, a user is able to attach and detach the cover 2 from the container 1. This supports storage and retrieval of foodstuffs, as well as other items that a person might wish to place within the container 1 of the present invention.

In the preferred embodiment, the various walls are offset are specific angles. More specifically, the first inner wall 15 is offset from the first ridge 17 by an obtuse angle 3 of 95 degrees. Correspondingly, the second inner wall 25 is angularly offset from the second ridge 27 by an obtuse angle 3 of 95 degrees.

Mirroring this, the first outer wall 16 is angularly offset from the first ridge 17 by an obtuse angle 3 of 95 degrees. The second outer wall 26, is also offset from the second ridge 27; however, this offset is at a right angle 4 (90 degrees) rather than an obtuse angle 3.

The preferred 95 and 90 degree offsets result in the inner walls and outer walls being orientated at a slight slant, relative to a supporting surface (e.g. a table), rather than perfectly perpendicular. Thus, the second lip 23 squeezes the first lip 13. This helps to securely attach the cover 2 to the container 1, creating an enclosed storage region interior to said container 1 and cover 2.

Another property of the present invention, when the cover 2 is attached to the container 1, is the second outer wall 26 being offset from the first outer wall 16. Put more simply, there is a small gap between the outside edge of the first lip 13 and the inside edge of the second lip 23.

In one possible embodiment, a base-receiving indent 29 is positioned into the top surface 21. This indent 29 is a depression that is sized to receive the base 11 of a similarly sized container 1. This feature enables “stacking” of the present invention, in which the base 11 of one container 1 is placed into the indent 29 of an adjacent cover 2.

While the illustrated embodiment shows the container 1 as having a circular shape, in other embodiments different shapes may be used. Regarding food storage, one of the most common alternatives are rectangularly shaped containers 1, but ultimately any shape may be used within the scope of the present invention.

Further, in alternative embodiments of the present invention, different values may be provided for the obtuse angles 3 previously referenced. For example, the first inner wall 15 may be angularly offset from the first ridge 17 by an obtuse angle 3 of 110 degrees, rather than 95 degrees. Other values for the obtuse angle 3 remain possible, as long as they are greater than 90 degrees and less than 180 degrees.

Addressing material construction for the present invention, a number of materials are suitable as long as they meet a few requirements. One requirement is a pliable construction for the cover 2, as it is necessary for the cover 2 to flex in order to fit onto the container 1. Also, as the present invention is primarily intended for food storage, the material used for the container 1 and the cover 2 is preferably food safe. As people often like to reheat stored food prior to consumption, in some embodiments it may be desirable to use a microwave-safe material for the container 1, the cover 2, or both.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
