Stretchable Protective Liners

Abstract

A liner to prevent damage to a portion of a fragile item, including at least its rim, includes a stretchable u-shaped ring edge member into which the rim of a fragile item may be inserted, and which frictionally engages the rim by contacting both the inner and outer surface of the fragile item adjacent the rim. The liner, in another variation, also includes a fabric covering that may be removably attached to the edge member and which stretches to cover the outer surface of the fragile item along with the rim. The liner or portions thereof comprise a dishwasher safe material which may have a mesh structure, so the liner can be left on during washing.

DETAILED DESCRIPTION OF THE INVENTION

[0023] In the Brief Summary of the Invention above, the Detailed Description of the Invention, the Claims, and in the accompanying drawings, reference is made to particular features of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a claim, that feature can also be used, to the extent possible, in other aspects and embodiments of the invention, and in the invention generally.

[0024] The term comprises and grammatical equivalents thereof are used herein to mean that other components, ingredients, steps, etc. are optionally present. For example, an article comprising (or which comprises) components A, B. and C can consist of (i.e., contain only) components A, B, and C, or can contain not only components A. B, and C but also one or more other components. Further, the term fragile items is used herein to mean dishware, bakeware, cookware, fine china, tableware, and the like of any shape or size made of or with a breakable material. To the extent a specific piece or type of fragile item is identified herein, it is understood that such identification also includes all other pieces or types of fragile items to the extent possible.

[0025] Here, a protective liner 10 for fragile items 20, including dishware and bakeware, to prevent breakage, chips, and cracks is provided. The liner 10 loop may be designed in several different shapes, similar to the shapes most commonly associated with specific pieces and types of fragile items 20, such as circular for cups, plates and bowls, and oval and/or rectangular for serving dishes and bakeware, etc. It is contemplated that the construction and design of the liner 10 is such that a single liner 10 may be used interchangeably for a variety of sizes and types of fragile items 20 with and without handles 30, including dishware, bakeware, and glassware. For example, a circular loop shaped liner 10 may be designed to be approximately 3 inches in diameter at rest; this same liner 10 may be stretched to attach to the rim 22 of a drinking glass that is approximately 4 inches in diameter, subsequently removed from the drinking glass and further stretched and attached to the rim 22 of a bowl that is approximately 6 inches in diameter. Furthermore, such a circular loop shaped liner 10 may also be designed to stretch over and attach to handles 30 adjacent to the rim 22 of the bowl, in addition to the rim 22 itself. Although the liner 10 may not have an infinite stretching ability, it is contemplated that the liner 10 may stretch at least several inches beyond its resting size to accommodate a variety of fragile items 20.

[0026] In a preferred embodiment, the liner 10 is constructed of a shock-absorbing viscoelastic polymer, such as silicone rubber, allowing it to stretch and conform to a multitude of different sizes and shapes. Examples of these viscoelastic polymers include Akton, Sorbothane, and Vistik. A viscoelastic material can be pushed, pressed, and stretched into a desired shape. That shape is then maintained until the material is removed and reshaped, thus allowing for a single protective liner 10 to accommodate a variety of shapes and sizes of fragile items 20. This type of material is also dishwasher safe and sufficiently heat resistant for use in an oven.

[0027] Further, in additional embodiments, it is foreseen that all or a portion of the liner 10 material may be solid and non-porous in structure or have a mesh structure comprising interlaced strands forming a porous mesh, as desired and as in FIGS. 5b, 5c, and 8. A liner 10 material having a porous mesh structure has the benefit of allowing cleaning of the covered surface of the fragile item 20 without removal of the liner 10 and without the unintended collection of water between the liner 10 and the covered surface of the fragile item 20. However, a liner 10 material having a solid non-porous structure has the benefit of providing the maximum protection to the covered fragile item 20. Consequently, a liner 10 comprising materials having both structures along various portions may provide a desired aggregation or balance of these benefits.

[0028] FIG. 1 illustrates a first embodiment of the present invention, whereby a stretchable, protective liner 10 comprising an edge member 12 is provided. When cross-sectioned, the edge member 12 is preferably designed in a U-shape or C-shapeas shown in FIG. 2for easily fitting over and frictionally engaging the upper rim 22 of a fragile item 20, like a bowl, drinking glass, or other dishware, without need of any additional attachment means, such as clamps suction cups, or the like. This first embodiment protects the rims/edges 22 of fragile items 20, like dishware and glassware, from breaks, chips, and cracks, as in FIGS. 7, 8, 9a, and 9b. Traditionally, when dishes are stacked and stored, the outer surface 24 of one dish will contact the inner surface of another dishas in FIG. 7; or, the bottom 28 of one dish will rest upon the rim 22 of another dishas in FIG. 8. It is not uncommon for dishes to chip and crack when stacked and stored in this manner. However, when a series of dishes are fitted with these protective liners 10 and subsequently stacked for storage, these liners 10 provide cushioning and protection when one dish contacts another dish, as shown in FIGS. 7 and 8. In addition, it is foreseen that these protective liners 10 may be fitted over and frictionally engage handles 30 adjacent the rim 22, in addition to the rim 22 itself, as in FIG. 9b.

[0029] Furthermore, this first embodiment may remain on a fragile item 20 while it is being washed, both by hand or in a dishwasher. It is common for glasses and dishes to collide or hit one another in a dishwasher, particularly if the dishwasher is full, resulting in cracks and chipped edges 22. Thereby, the present invention may provide cushioning and protection to such fragile items 20 during washing. Additionally, as stated previously, the liner 10particularly the edge member 12may also be constructed of a material having a mesh structure, thereby allowing for more effective cleaning of the covered fragile item 20 and reducing the likelihood that water from washing will collect between the fragile item 20 and edge member 12.

[0030] In a second embodiment, the liner 10 may also comprise a stretchable, cushioning fabric covering 14 attached to the inner portion of the viscoelastic edge member 12, as shown in FIGS. 3 and 4. The fabric covering 14 may be permanently or removably attached to the edge member 12. The edge member 12 may be removably attached to the fabric covering 14 through complementary hook and hoop fastener assemblies, snap fit or traditional buttons, interlocking tab and pocket segments, or the like. There are many means for removably attaching such segments and one skilled in the art will recognize that any suitable means for providing removable attachment may be employed. Whether permanently or removably attached, the edge member 12 may be attached to the fabric covering 14 in such a way that the covering 14 is pulled and stretched around the outer surface 24 of a fragile item 20including the outer sides 26, any handles 30, and bottom 28as the edge member 12 fits over and frictionally engages the upper lip or rim 22 thereof. For example, a baking dish may be centered on top of the fabric covering 14 attached to an edge member 12 of such a liner 10 and the fabric covering 14 may then be stretched around the outer sides 26 of the dish as the edge member 12 is pulled up and fitted around the rim 22 thereof, as shown in FIGS. 5a. 5b, 5c, and 6. In this way, the outer surface 24, including the sides 26, any handles 30 (as in FIG. 5b), and bottom 28 of a fragile item 20, as well as the upper rim 22, may be cushioned and protected during use and storage.

[0031] Further, this second embodiment may be preferred for use during long-term storage of fragile items 20, for packing such during a move, or for storage of such that are exceptionally fragile or valuable, such as fine china and crystal. FIG. 6 shows plates 20 covered with such a liner 10 stacked together so it can be seen that no plate 20 contacts another without some portion of the liner 10 therebetween to cushion such contact. Also, while it is foreseen that the fabric covering 14 may cover handles 30 (as in FIG. 5b), it is also possible that in additional embodiments the fabric covering 14 may also have handle members 16 attached on the outside thereof, as in FIG. 5c. Thereby, a fragile item 20 not having handles 30 may be protected and provided with handle members 16 to facilitate easier transport.

[0032] Although it is preferable to remove this second embodiment prior to washing so that the outer surface 24 of a fragile item 20 may be cleaned without any interference, it is foreseen that this second embodiment may also remain on a fragile item 20 while it is being washed, both by hand or in a dishwasher. Thereby, the present invention may provide enhanced cushioning and protection to such fragile items 20 during washing than that of the first embodiment. Additionally, the fabric covering 14in place of or addition to the edge member 12may also be constructed of a material having a mesh structure, in addition to being dishwasher safe, thereby allowing for more effective cleaning of the covered fragile item 20 with the liner 10 still on and reducing the likelihood that water from washing will collect between the fragile item 20 and fabric covering 14.

[0033] Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein. All features disclosed in this specification may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features. Further, it is not necessary for all embodiments of the invention to have all the advantages of the invention or fulfill all the purposes of the invention.
