Abstract

A disposable and conformal liner that completely and internally seals a container and an associated lid. The container has a bottom portion and two pair of side portions. The two pair of side portions of the container extend upwardly from the bottom portion of the container to a rim, and are attached to each other adjacently. The disposable and conformal liner includes a bottom section, two pair of side wall sections, and a pair of flap sections. The two pair of side wall sections extend upwardly from respective sides of the bottom section and are continuous with each other adjacently, so as to form a box-like main body. The box-like body is conformingly received in the container. The pair of flap sections extend from an opposing pair of side wall sections to free ends. The free end of one flap section is folded onto itself and is bonded thereat so as to form a reinforced strip, leaving a remaining portion of the one flap section a same size as the other flap section.

Description

BACKGROUND OF THE INVENTION

Field of the Invention

The embodiments of the present invention relate to a liner, and more particularly, the embodiments of the present invention relate to a disposable and conformal liner for completely and internally sealing a container and an associated lid.

Description of the Prior Art

With RVs having limited space and water, cleanup of plastic storage containers is always an issue.
Not only is there a need to overcome this problem, the embodiments of the present invention are both useful and necessary in every household that uses plastic storage containers for leftovers or takes them work/school/gym, parties.
Splatter is caused in a microwave when just the bowl is heated in the microwave and the lid is off. Food can suffer from freezer burn. Containers, such, as a Tupperware plastic storage container, can become stained by foods and become unclean.
Lid portions of the containers are not reconfigurable into different sizes from square to rectangular, etc.
The container or the lid do not work like gaskets when the lid is placed on the container, thus keeping the food fresher for less time.
The liners do not come in different sizes to accommodate different sized containers.
Numerous innovations for container liners have been provided in the prior art, which will be described below in chronological order to show advancement in the art, and which are incorporated herein in their entirety by reference thereto. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the embodiments of the present invention, in that they do not teach a disposable and conformal liner for completely and internally sealing a plastic storage container and an associated lid. For example:

U.S. Pat. No. 3,933,263 to Frew et al

U.S. Pat. No. 3,933,263—issued to Frew et al. on Jan. 20, 1976 in U.S. class 215 and subclass 12.1—teaches a container having a disposable liner of a flexible plastic composition. The liner incorporates an elasticized overlap to cooperate with one or more ridges on the container in holding it in place while in use.

U.S. Pat. No. 4,122,973 to Ahern

U.S. Pat. No. 4,122,973—issued to Ahern on Oct. 31, 1978 in U.S. class 220 and subclass 495.02—teaches a re-use and extended use paint bucket of conventional form and proportions by disposable, thin, and internal fluid-tight liners that are vacuum-formed from relatively thick thermoplastic sheet material. Each liner has, exceedingly thin bottom and side walls, but is self-sustaining in shape because of circular stiffening by a thick upper rim shaped to snap-lock with, and overhang, the bucket rim, and also because of longitudinal stiffening imparted by several inwardly-projecting hemicylindrical ribs disposed along the side walls where they will serve as vents, which facilitate insertion and removal of the close-fitting bucket liner.

U.S. Pat. No. 5,402,906 to Brown et al

U.S. Pat. No. 5,402,906—issued to Brown et al. on Apr. 4, 1995 in U.S. class 426 and subclass 106—teaches a packaging system for fresh produce, such as, fresh lettuce and the like food products. The packaging system relies upon a quadrilaterally shaped and fairly rigid paperboard container having more than four corner portions therein and with an inner liner used for the storage and transport of the produce, such as, lettuce heads. In a preferred embodiment, the containers are octagonal shaped with four rectangular shaped elongate walls connected at their corner portions by four relatively short angularly located connecting walls. Portions of these containers, and, particularly, the side walls are capable of being reused. Moreover, they are adapted for storage and transport in stacked relationship and also fit upon conventional pallets.

The covering includes a flexible sheet of predetermined size and thickness and has a rectangular grid of weakened lines to provide rectilinear yield lines extending in a first direction and in a second direction at right angles to the first direction to enable tearing by hand along selected ones to the grid lines as a tear in a first direction. The sheet has individual perforations extending completely through its thickness and located at the points of intersection of the axes of the weakened lines. The perforations facilitate changes in the direction of a tear at a selected point of intersection and to extend the tear in the second direction so as to achieve a desired size of sheet. The weakened lines further include tear lines extending diagonally between perforations to facilitate changes in the direction of tearing and to provide relieved corners to better fit into locations, such as, the corners of drawers, enclosed shelves, etc. The covering sheet has an adhesive layer, such as, a pressure-sensitive adhesive on its reverse surface, and with the perforations extending also through the adhesive layer and through a release medium covering the adhesive layer face of the sheet. The perforations may include a reticulated series of through-cut and micro-perforations arranged in oriented relation with the edges of the sheet. The release medium is a removable sheet on the reverse face covering the adhesive layer or it is applied in covering relation with the obverse face of the sheet when the covering sheet is supplied in rolled and self-wound form usually upon a cardboard cylinder.

U.S. Pat. No. 6,679,398 to O'Brien

U.S. Pat. No. 6,679,398—issued to O'Brien on Jan. 20, 2004 in U.S. class 220 and subclass 495.02—teaches a paint container liner system including disposable liners and an open container for receiving at least one of the disposable liners. The liners are sized and configured to fit into the inside of the container and around the rim of the container.

Referring now to the figures, and particularly FIG. 1, the disposable and conformal liner of the embodiments of the present invention is shown generally at 10 for completely and internally sealing a container 12 and an associated lid 14, wherein the container 12 has a bottom portion 16 with a shape and size and two pair of side portions 18 with shapes and sizes, and wherein the two pair of side portions of the container 12 extend upwardly from the bottom portion 16 of the container to a rim 20 and are attached to each other adjacently.
It is to be understood that the container 12 is a plastic storage container, such as, but not limited to, Tupperware®, of any shape and size.

The Overall Configuration of the Disposable and Conformal Liner 10

The overall configuration of the disposable and conformal liner 10 can best be seen in FIGS. 2 and 3, and as such, will be discussed with reference thereto.
The disposable and conformal liner 10 is one-piece and comprises a bottom section 22, two pair of side wall sections 24, and a pair of flap sections 26. The two pair of side wall sections 24 extend upwardly from respective sides of the bottom section 22 and are continuous with each other adjacently so as to form a box-like main body 28 for being conformingly received by the container 12. The pair of flap sections 26 extend from an opposing pair of side wall sections 24 to free ends 30. The free end 30 of one flap section 26 is folded onto itself and is bonded thereat so as to form a reinforced strip 32, leaving a remaining portion 34 of the one flap section 26 a same size as the other flap section 26.
It is to be understood that the one flap section 26 can be folded and bonded onto itself from either the top or the bottom of the one flap 26.

The Specific Configuration of the Bottom Section 22

The specific configuration of the bottom section 22 can best be seen in FIGS. 2 and 3, and as such, will be discussed with reference thereto.
The bottom 16 has a size and a shape defined by a perimeter 36 and is for substantially matching the size and shape of, and for conformingly overlying, the bottom 16 of the container 12.

The Specific Configuration of the Two Pair of Side Wall Sections 24

The specific configuration of the two pair of side wall sections 24 can best be seen in FIGS. 2 and 3, and as such, will be discussed with reference thereto.
The two pair of side wall sections 24 extend upwardly from the perimeter 36 of the bottom 16 to a top 38, in which the tops 38 of a pair of opposing side wall sections 24 are for overlapping the rim 20 of the container 12 so as to form a gasket 40 when the lid 14 is pressed applied onto the container 12 for the purpose of fully covering contents of the container 24, and have shapes and sizes for substantially matching the shapes and sizes of, and for conformingly overlying, the two pair of side portions 18 of the container 12.

The Specific Configuration of the Pair of Flaps 36

The specific configuration of the pair of flaps 36 can best be seen in FIGS. 2-4, and as such, will be discussed with reference thereto.
The pair of flaps 36 have end portions 42 and extend foldingly from the tops 38 of the other two opposing side wall sections 24, and when in a no-use position, drape freely downwardly (FIG. 3), and when in a in-use position, fold inwardly over contents of the container 12, with the free ends 30 of the other pair of opposing side wall sections 24 overlapping each other with the reinforced strip 32 of the free ends 30 of the other two opposing side wall sections 24 being on the underneath (FIG. 4), and with the end portions 42 being for overlapping the rim 20 of the container 12 so as to contribute to the gasket 40 when the lid 14 is pressed applied onto the container 12 for the purpose of fully covering contents of the container 24.
The liner is placed in the plastic storage container and holds an item to be stored within without the contents making contact with the Tupperware type plastic storage container.
The liners are shaped and sized to fit specific Tupperware type plastic storage containers; in this way the plastic storage containers can be used as the packaging (placing the liners within the plastic storage containers). Obviously, the liners can be sold separately as replacements.
The problems the liner solves include:

- Eliminating staining of plastic storage containers and lids;
- Reducing odors;
- The contents and liner can be removed from the plastic storage container eliminating washing the plastic storage containers thereby saving water;
- Saved food lasts longer;
- Eliminating grease from entering drain/septic;
- Protecting against freezer burn by forming an additional barrier;
- The liners are microwave safe;
- BPA free; and
- Recyclable.
