Description
Technical Field
This invention relates, generally, to insulated cup holders. More particularly, it relates to an insulated cup holder with a flexible base member and a structure that relates breakage.
Background Art
Beverage cans are thin walled and it is well known that the temperature of a potable contained within a can changes quickly to ambient temperatures once such a can it taken from a controlled temperature storage location.
Moreover, cups with handles are also essentially uninsulated. Accordingly, inventors have devised quite a few different devices that serve to keep hot drinks hot and cold drinks cold.
A U.S. Design Patent to Bradley, U.S. Pat. No. D. 281,755, shows a holder for a drinking vessel that includes a flexible base member.
U.S. Pat. No. 2,803,366 to Forman shows a combination pot and holder that includes a shallow slot or cut-away portion that accommodates a lowermost portion of a handle for a coffee pot.
An insulated holder for a beverage can is shown in U.S. Pat. No. 3,013,691 to Prentice; further examples of insulated can or cup holders are shown in U.S. Pat. Nos. 3,302,427, 3,302,428, 4,383,422, 4,681,239 and 3,285,455.
One shortcoming of these earlier devices is their tendency to tip over easily. Another shortcoming is their inability to receive cups having handles. Still another limitation is that these earlier devices do not protect fragile beverage containers from damage; indeed, the insulated containers of the prior art are themselves easily breakable.
It is therefore apparent that there is a need for an insulated cup holder that is not easily tipped over and which may accommodate cups with handles. A need also exists for a cup holder that protects fragile beverage containers against breakage and which itself is substantially unbreakable.
The patents of the prior art, however, neither teach nor suggest how a cup holder not subject to the limitations of the prior art could be provided.
Disclosure of Invention
The long-standing but heretofore unfulfilled need for an improved insulated cup holder is now provided in the form of a device having a stable support means that resists tipping, a cup handle-receiving slot and a rigid frame member that guards fragile containers and which prevents the facile destruction of the device itself as well.
The stable support means includes a flexible bag means that is completely filled with particulate or granular matter of the type found in bean bag chairs or of other types, such as stone or other matter.
In a first embodiment, the flexible bag means is fixedly secured about its uppermost periphery to the bottom of a rigid, cylindrical in configuration frame member that is lined with a layer of insulation. The frame member has an imperforate bottom wall which cooperates with the flexible bag member to enclose the granular matter. A cup-engaging, rim-mounted cup supporting means holds a cup inserted into the open upper end of the device in spaced relation to the insulating material so that a small, insulating air space separates the cup from said insulating material.
In a second embodiment, a flexible bag means extends to the upper periphery of the container and the bag is completely filled with granular material. Thus, the granular bag filler surrounds the insulated frame member, thereby providing a double insulation means.
Where a fragile beverage container such as a styrofoam cup is inserted into the holder, any downwardly directed forces will be resisted by the rigid frame member, thereby extending the usable lifetime of the cup and that of the inventive device as well.
Where a cup of the type having a handle is desired to be insulated, the handle thereof is aligned with a slot formed in the device and the cup is slidably inserted thereinto.
The particles contained in the flexible bag means which depends to the frame member are free flowing; accordingly, when the device is placed upon an uneven surface, the flexible bottom wall of the bag member conforms to the contour of such surface. The uneven position of the bag bottom wall is not communicated to the rigid frame member due to the flowability of the particulate matter, i.e., the top layer of the particles may be level while the underlying mass of particles may be uneven. The flat bottom wall of the rigid frame member is simply placed in a level disposition by the user of the invention to conform the upper regions of particles to a level configuration, without regard to the uneven configuration of the lower regions of particles.
Another embodiment of the invention provides a frame member having an upwardly extending, non-insulated portion that enhances the protection of the insulation lining the balance of the frame member. The extension portion is externally threaded to screw-threadedly receive an internally threaded cup supporting means.
The primary object of this invention is therefore seen to include the provision of a tipping-resistant insulated container that may be placed on non-level surfaces.
Other objects of this invention relate to the provision of a handle-accommodating insulated container that has a rigid frame means which protects fragile containers when they are positioned therein and which preserves the structural integrity of the device as well.
The invention accordingly comprises the features of construction, combination of elements and arrangement of parts that will be exemplified in the descriptions set forth hereinafter and the scope of the invention will be set forth in the claims.

Best Modes for Carrying Out the Invention
Referring now to FIG. 1, it will there be seen that an illustrative embodiment of the present invention is designated by the reference numeral 10 as a whole. Device 10 includes a rigid, cylindrical in configuration frame member 12 that includes cylindrical sidewalls 14 and a flat, imperforate bottom wall 16.
The interior surface of sidewall 14 is lined with a layer of suitable insulating material 18 such as styrofoam. Material 18 is permanently bonded to frame 12 by a suitable adhesive, not shown. Reference numeral 19 denotes the cup-receiving cavity of this invention.
A cup-engaging and cup-centering member 20 is press fit to the upper rim of the device 10 as shown. Member 20 includes plural radially-inwardly directed flexible cup-supporting means, collectively designated 21, (FIG. 3) which transiently displace downwardly when a cup is slidably inserted into cavity 19 as shown in FIG. 2.
As shown in FIGS. 2, 6, 7 and 9, cup-supporting means 21 centers a slidably inserted cup member 22 with respect to cavity 19 so that an insulating area of dead air space 24 surrounds cup 22. In this manner, device 10 provides two types of insulation, i.e., that of insulating material 18 and that of airspace 24.
Frame member 12 is supported by a flexible support means, designated 26 as a whole. Support means or base member 26 includes a bag means fixedly secured, by a suitable means, to frame member 12 as shown; it is formed of a suitable flexible material such as leather, imitation leather, or the like. Base member 26 includes flexible sidewalls 28 and flexible bottom wall 30, all of said walls 28 and 30 being imperforate. The upper annular periphery of the bag means may be secured to the lowermost annular periphery of frame member 12 or the bag means may be attached as shown so that the granular material 32 is enclosed within the cavity 34 defined by the bag means 26.
Preferably, bag means 26 is completely filled with granular material 32 as shown in FIG. 1.
Accordingly, bottom wall 16 of frame 12 rests atop a level layer of particulate material 32 when the invention is in use.
Of particular interest is the uneven surface 36 upon which the device 10 is shown resting in FIG. 1. Flexible bottom wall 30 of bag means 26 conforms to the contour of the surface 36 as shown. Due to the presence of the granular material 32, this uneven contour is not transmitted to bottom wall 16 of rigid frame member 12. In this manner, device 10 has utility even when placed upon the most irregular of surfaces. Moreover, the weight of material 32 provides a high degree of stability to the device.
If device 10 is struck with a lateral blow, frame member 12 will shift position in response thereto, but it will not tip over, due to the weight and fluidity of the granular material.
To further enhance the non-slip characteristic of the device, a plurality of non-skid members 38 are fixedly secured to the exterior surface of bag bottom wall 30 a shown in FIG. 4.
If device 10 is stepped on or otherwise subjected to downwardly directed forces impinging thereagainst as denoted by the single-headed directional arrow 40 in FIG. 1, the soft styrofoam 18 will be guarded by the rigid frame member 12. Said frame 12 may be formed of any suitable rigid material, but it is preferably formed of a lightweight, high impact plastic.
Thus, frame 12 is seen to be an important feature of this invention.
The slot means 42 shown in the FIG. 1 embodiment is another important feature; it slidingly receives the handle portion of a cup of the type having a handle as shown in FIG. 2.
Referring now to FIG. 7, it will there be seen that still another embodiment of the invention is denoted by the reference numeral 44 as a whole. It differs from the embodiments described above in three important respects. As shown, rigid frame member 12 and the insulating material 18 are not co-extensive in this embodiment in that the cylindrical sidewalls 14 of frame 12 extend upwardly beyond the uppermost periphery of said insulation 18; specifically, reference numeral 46 denotes that portion of sidewalls 14 that extend beyond the uppermost periphery 18A of said insulating material 18.
Secondly, cup supporting or cup-centering member 20 is different in the embodiment of FIG. 7, and is denoted 21a. Specifically, cup supporting member 20A is internally threaded as at 48 and portion 46 of sidewall 14 is externally threaded as at 50 to screw-threadedly engage the same.
In this manner, the structural integrity of apparatus 44 is enhanced. It should be observed that insulation 18 could extend all the way to the top of frame portion 46, but it is believed that the styrofoam 18 is better protected by extending frame 12 sidewalls 14 as shown.
The third of the above-mentioned differences is the unbonded relationship between the insulating material 18 and the sidewalls of frame 12 in this embodiment. Not bonding styrofoam 18 to the interior sidewalls of frame 12 permits removal and replacement of such insulation 18 if it becomes damaged. Moreover, frame 12 can be used as a cup means should styrofoam 18 break and there be no replacement readily available therefor.
FIGS. 8 and 9 show embodiments where bag means 26 surrounds frame member 12 and is completely filled with granular material 32 as shown. This structure further increases the insulating properties of the container. In fact, container holders having both insulated material 18 and 32 were heretofore unknown. The insulation 18 of the earlier-described embodiments could also be provided in non-bonded form; thus, this invention is not restricted to bonded or unbonded insulating material.
The unique, flowable, weighted base member of this invention, together with the crush-resistant frame member and the other features of this invention, provide ample evidence that this invention has advanced the art of insulated cup holders.
