Description

RADIATOR CAP SAFETY COVER TECHNICAL FIELD
The disclosure of the present patent application relates to the vehicle radiator caps, and particularly to a radiator cap safety cover that deflects hot steam and liquid droplets expelled from an overheated radiator when the radiator cap is removed.
BACKGROUND ART
When a radiator cap is removed from an overheated vehicle radiator, steam and heated droplets of coolant are expelled from the radiator at high speed. The heat of the steam and droplets is typically sufficient to cause severe burns to any skin exposed to the heated fluid stream. Although it is very common to use a rag when removing a radiator cap, the fabric of the rag provides minimal protection to the user, partially because of its porous nature and partially because its coverage is typically little greater than the diameter of the radiator cap, leaving a wide angular span for the fluid that is not blocked at all. Conventional radiator caps are not provided with any additional covering or shielding for protecting the user from accidental bums. Thus, a radiator cap safety cover solving the aforementioned problems is desired.
DISCLOSURE OF INVENTION
The radiator cap safety cover is a thermally insulating cover for a radiator cap that is shaped to deflect hot steam and liquid droplets expelled from an overheated radiator when the radiator cap is removed. The radiator cap safety cover includes a central portion, an annular wall, and an annular flange. The annular wall has opposed upper and lower ends, and the upper end being secured to the perimeter of the central portion. The annular flange is secured to the lower end of the annular wall and extends outwardly therefrom. The annular flange includes first, second and third portions, where the first portion extends substantially parallel to the central portion, the second portion is angled with respect to the first portion, and the third portion is angled with respect to both the first portion and the second portion. The central portion and the annular wall define a central cavity adapted for receiving the radiator cap.
The central portion, the annular wall and the annular flange are all made from a resilient and thermally insulating material, thus not only providing protection for the user, but also allowing for the radiator cap safety cover to securely and releasably cover and receive the radiator cap. When not in a deformed state (such as when the radiator cap is being received or removed), the central portion is substantially planar. The central portion may be formed as a planar circular disc.
A first angle between the first portion and the second portion of the annular flange is greater than a second angle between the second portion and the third portion of the annular flange. Thus, the combination of the first and second portions shields the user from the steam and droplets of radiator coolant and provides some deflection thereof, and the combination of the second and third portions deflects the steam and droplets downward, away from the user’s hand, torso and face.
Additionally, a gripping member may be secured to the upper surface of the central portion, providing the user with leverage for twisting and removing the radiator cap from the radiator. An annular rim may be further secured to the lower end of the annular wall and extend inward therefrom, thus providing secure gripping for the bottom edge of the radiator cap when the radiator cap is received within the central cavity of the radiator cap safety cover. The central portion, the annular wall, the annular flange, the gripping member and the annular rim may all be integrally formed as a single molded article formed from the thermally insulating and resilient material.
These and other features of the present subject matter will become readily apparent upon further review of the following specification.

BEST MODES FOR CARRYING OUT THE INVENTION
The radiator cap safety cover 10 is a thermally insulating heat-resistant cover for a radiator cap C, and is shaped to deflect hot steam and liquid droplets expelled from an overheated radiator when the radiator cap C is removed. As shown in Figs. 1 and 2, the radiator cap safety cover 10 includes a central portion 12, an annular wall 14, and an annular flange 32. It should be understood that the overall configuration and relative dimensions of the central portion 12, annular wall 14 and annular flange 32 are shown for exemplary purposes only. It should be further understood that the radiator cap C is shown for exemplary purposes only, and that radiator cap safety cover 10 may be used with any conventional style of radiator cap C. The annular wall 14 has opposed upper and lower ends 16, 18, respectively, and the upper end 16 is secured to the perimeter 34 of the central portion 12. The annular flange 32 is secured to the lower end 18 of the annular wall 14 and extends outward therefrom.
As best seen in Fig. 2, the annular flange 32 includes first, second and third annular portions 24, 26, 28, respectively, where the first portion 24 extends substantially parallel to the central portion 12 (i.e., horizontally in the particular orientation of Fig. 2), the second portion 26 is angled with respect to the first portion 24, and the third portion 28 is angled with respect to both the first portion 24 and the second portion 26. The central portion 12 and the annular wall 14 define a central cavity 20 adapted for installation over and covering the radiator cap C. The central portion 12, the annular wall 14 and the annular flange 32 are all made from a resilient and thermally insulating heat-resistant material, thus not only providing protection for the user when gripping a hot radiator cap, but also allowing for the radiator cap safety cover 10 to securely and releasably grip and cover the radiator cap C. When not in a deformed state (such as when the radiator cap C is being received or removed), the central portion 12 is substantially planar. The central portion 12 may be formed as a planar circular disc, as in the example of Fig. 1.
A first angle a between the first portion 24 and the second portion 26 of the annular flange 32 is greater than a second angle P between the second portion 26 and the third portion 28 of the annular flange 32. Thus, the combination of the first and second portions 24, 26 shields the user from the steam and droplets of radiator coolant and provides some deflection thereof, and the combination of the second and third portions 26, 28 deflects the steam and droplets downward, away from the user’s hand, torso and face.
Additionally, a gripping member 22 may be secured to the upper surface 36 of the central portion 12, providing the user with leverage for twisting and removing the radiator cap C from the radiator. It should be understood that the elongated, bar-like gripping member 22 shown in Fig. 1 is shown for exemplary purposes only, and that the gripping member 22 may have any suitable dimensions and configuration.
An annular rim 30 may be further secured to the lower end 18 of the annular wall 14 and extend inwardly therefrom, thus providing secure gripping for the bottom edge of the radiator cap C when the radiator cap C is encased within the central cavity 20 of the radiator cap safety cover 10. The central portion 12, the annular wall 14, the annular flange 32, the gripping member 22 and the annular rim 30 may all be integrally formed as a single, molded article formed from the thermally insulating heat-resistant and resilient material. It is to be understood that the radiator cap safety cover is not limited to the specific embodiments described above, but encompasses any and all embodiments within the scope of the generic language of the following claims enabled by the embodiments described herein, or otherwise shown in the drawings or described above in terms sufficient to enable one of ordinary skill in the art to make and use the claimed subject matter.
