This invention relates to protective article carriers, and more particularly to a carrier for bottles and other containers that protects such container against damage from impact and or vibration, is adaptable to multiple container sizes, and is collapsible for easy transport and storage when not in use.
Protective covers and carriers for fragile articles, such as bottles, are known in the art. Some such covers may include, for instance, inflatable bags that when inflated provide one or more air pockets around the article. Unfortunately, however, such inflatable bags are typically not easy to use, are bulky in appearance, and are unsuitable for storage in a cooler. Likewise, tote bags made of various materials, including neoprene, have been provided, and while they may provide a more stylish appearance, they typically provide minimal impact protection for the fragile article, and should the article break, typically do nothing to contain the breakage.
The invention relates to a protective sleeve for fragile articles, and more particularly to a collapsible, aesthetically pleasing, impact-protective sleeve for fragile articles, which protective sleeve may be optionally adapted for submersion in a cooler or fluid-filled container without wetting the article.
According to embodiments of the invention, a primary structural component of the protective sleeve is molded foam panels having pillars integrally molded thereon.

The following description is of particular embodiments of the invention, set out to enable one to practice an implementation of the invention, and is not intended to limit the preferred embodiment, but to serve as a particular example thereof. Those skilled in the art should appreciate that they may readily use the concepts and specific embodiments disclosed herein as a basis for modifying or designing other articles and systems for carrying out the same purposes of the present invention. Those skilled in the art should also realize that such equivalent assemblies do not depart from the spirit and scope of the invention in its broadest form.
As shown in the perspective view of
In order to provide shock protection for the bottle, sleeve 100 is preferably comprised primarily of an impact resistant material. In certain embodiments, such impact resistant material may comprise relatively low viscosity or low durometer polymeric materials such as polymeric gel materials, and more particularly viscoelastic polymeric materials or “gels” as described in copending and commonly owned U.S. patent application Ser. No. 12/423,174 and U.S. patent application Ser. No. 12/102,859, the specifications of which are incorporated herein in their entireties. In other embodiments, such impact resistant material may comprises rate dependent foams, such as those available from Rogers Corporation under the brand names PORON® and PORON XRD®, both of which are open cell, microcellular polyurethane foams, as further described in U.S. patent Application Ser. No. 13/271,594, the specification of which is incorporated herein in its entirety.
As shown in
In addition to such foam material, and again with reference to
More particularly, and with reference now to
In a particularly preferred embodiment, the dimensions of panels 122, and thus of fully assembled sleeve 100, are optimally configured so as to allow sleeve 100 to contain a bottle having a diameter of approximately 2.7 inches to approximately 3.5 inches, and a height of approximately 11.5 inches to approximately 13 inches.
In some embodiments, stretch fabric sections 112 and 114 may not be included. In this case, the flexibility of the impact resistant material that comprises foam panels 120 may be sufficient to receive and accommodate bottles or other containers of varying sizes by stretching the material along the length and diameter of the sleeve when used with larger bottles.
Hollow cup 106 may be sewn, glued, laminated, or otherwise fastened to end cap 120, and hub 108 may be sewn, glued, laminated, or otherwise fastened to end cap 104. Each end cap is then preferably removable attached to sleeve 100 through the use of clip bands 130. More particularly, clip bands 130 are preferably glued, sewn, or otherwise affixed to rectangular panels 122 at clip band sewing flanges 132, each of which is preferably 2 inches tall and ⅜ inches wide, and which are permanently affixed to rectangular panels 122. Each clip band 130 is then attached to either end cap 102 or end cap 104. In order to allow for the removal of end cap 102 and/or end cap 104, clip bands 130 may be sufficiently flexible so as simply allow a user to temporarily displace one of the end caps from the end of sleeve 100 and, once a bottle or other container has been inserted in or removed from the sleeve 100, replace the end cap, allowing the tension in clip bands 130 to hold the end cap in place. Alternatively, select ones of clip bands 130 may be removably attached to its respective end cap, such as by use of hook and loop fastening material, snaps, or other similarly configured connectors, whereby detaching such removable portions of clip bands 130 from its respective end cap will allow displacement of at least that portion of the end cap from sleeve 100, again allowing insertion of a bottle into sleeve 100 or removal of a bottle therefrom. Once the bottle is so inserted or removed, the end cap may be replaced and clip bands 130 reattached to such end cap to hold it in place on sleeve 100.
Preferably, and as shown in
While the foregoing assembly comprises a generally cylindrical form, it is of note that when a bottle or other container is not positioned within sleeve 100 and end caps 102 and 104 are removed therefrom, the entirety of the assembly is collapsible into a generally flat structure having a thickness no greater than the thickness of two body panels 120. Thus, such sleeve is capable of providing significant impact and vibration resistance when a bottle or other container is positioned within sleeve 100, but likewise may be easily collapsed into an easily transportable package when not in use.
In order to keep sleeve 100 waterproof, a protective waterproof film or other treatment is applied to foam panels 120 using such waterproofing materials as are readily available and known to those skilled in the art. Similarly, stretch fabric portions 112 and 114 may likewise be treated with a protective, waterproof film or other waterproofing treatment as are readily available and known to those skilled in the art.
In an alternative embodiment, several of the above-described components may be provided in the form of a case configured for transporting multiple bottles or other containers while providing impact and vibration resistance. More particularly, a generally rectangular box may be provided as an outer container sized to fit multiple bottles or other containers. In this embodiment, body panels 120 may be sandwiched between and affixed to an exterior, preferably vinyl layer and an interior, preferably fabric layer to form a rectangular box, each side of which includes a shock and vibration resistant body panel 120 to provide protection for the contents of the box. A plurality of hollow cups 106 and aligned hubs 108 may, either alone or with end cap assemblies similar in configuration to end caps 102 and 104, be positioned along an interior side of the top of the box and an interior side of the bottom of the box, thus forming pairs each of which may position a bottle or other container positioned within the box. Optionally, the plurality of hollow cups 106 and aligned hubs 108 may be removable attached to the interior surfaces of the box, such as by hook and loop fastening materials, snaps, or similarly configured connectors. Moreover, so as to further protect the plurality of bottles or other containers so positioned within the box, accordion inserts may also be provided to separate the bottles from one another. In that case, the accordion inserts are preferably formed of the same hexagonal foam used for inserts 120, thus providing further impact and vibration protection to the bottles positioned within the box.
