Abstract
A non-pressurized fluid reservoir for a vehicle coolant system includes a bottle configured to store fluid. The bottle has a neck defining an inner circumferential surface that is devoid of threads. The reservoir further includes a cap having a lid and a shank extending from the lid. The shank has an outer circumferential surface and with a spiral ramp supported on the outer circumferential surface to encircle a portion of the shank. The shank is receivable within the neck with the spiral ramp adjacent to the inner circumferential surface to mitigate fluid leaks through the neck.
Claims16
A non-pressurized fluid reservoir for a vehicle coolant system comprising:
- a bottle configured to store fluid, the bottle having a neck defining an inner circumferential surface that is devoid of threads;
- and a cap having a lid and a shank extending from the lid, the shank having an outer circumferential surface and having a spiral ramp, wherein the spiral ramp includes a first end proximal to the lid and a second end distal to the lid, the spiral ramp supported on the outer circumferential surface to encircle a portion of the shank, wherein the shank is receivable within the neck with the spiral ramp disposed against the neck and adjacent to the inner circumferential surface to mitigate fluid leaks through the neck.
A non-pressurized vehicle cooling system comprising:
- a coolant loop;
- a bottle in fluid communication with the coolant loop, the bottle having a neck and a porous medium that extends over an end of the neck to suppress fluid flow from the bottle into the neck, wherein the neck defines an inner circumferential surface that is devoid of threads;
- and a cap having a lid and a shank extending from the lid, the shank having an outer circumferential surface and having a spiral ramp supported on the outer circumferential surface to encircle a portion of the shank, wherein the shank is receivable within the neck with the spiral ramp adjacent to the inner circumferential surface to mitigate fluid leaks through the neck.
A non-pressurized fluid reservoir for a vehicle coolant system comprising:
- a bottle configured to store fluid, the bottle having a top defining a neck and a sidewall joined to the top by a rolled edge configured to redirect fluid downwardly, wherein the rolled edge is formed around the complete perimeter of the bottle, and a top portion of the rolled edge is higher than an upper most portion of the top;
- and
- a cap connectable to the neck such that an interior of the bottle is in fluid communication with the atmosphere, wherein the neck defines an inner circumferential surface that is devoid of threads, and wherein the cap has a lid and a shank extending from the lid, the shank having an outer circumferential surface and having a spiral ramp supported on the outer circumferential surface to encircle a portion of the shank, wherein the shank is receivable within the neck with the spiral ramp adjacent to the inner circumferential surface to mitigate fluid leaks through the neck.
