The present invention relates in general to drinking tumblers for beverages.
It is common for drinking tumblers for beverages to include a cover to reduce spilling. It is also known for these covers to include a selectively closable spout. To reduce vacuum lock and improve flow from the spout, it is also known for these covers with spouts to also include a separate vent opening spaced from the spout. It has been found, however, that disturbing such a tumbler while closed and filled with hot beverage can result in a spray of hot liquid from the vent opening.
An object of the present invention is to provide a tumbler for a beverage which includes a cover having a selective closable spout and vent opening.
Another object of the present invention is to provide such a tumbler which further includes a vent shield to divert any spray from the vent opening.
A further object of the present invention is to provide such a tumbler wherein the vent shield is formed as a part of the spout closure.
These and other objects are achieved by a tumbler with vent shield.
The objects and features of the invention noted above are explained in more detail with reference to the drawings, in which like reference numerals denote like elements, and in which:
With reference to
As best shown by comparison of
The cover 14 also includes a spout cap 24 for selectively closing the spout opening 22. In particular, the spout cap 24 may be selectively moved from a closed configuration to an open configuration. This is meant in a general sense: in the closed configuration the spout opening 20 is blocked by the spout cap 24 sufficiently to reduce spilling of the beverage; in the open configuration spout opening is not blocked by spout cap 24 sufficiently to allow dispensing. There are a wide variety of spout caps known, and the present invention may be used with most if not all. The spout cap 24 could be completely removable from the cover 14; the spout cap 24 could be hinged to cover 14 along an axis in the plane of the cover 14 and pivot between configurations; the spout cap 24 could slide on cover 14 between configurations; the spout cap 24 could be rotatable mounted to cover 14 about an axis normal to cover 14 for oscillation or rotation between configurations. This last possibility is shown in the drawings.
The cover 14 includes a pin opening 26 spaced from the spout opening 22, and the spout cap 24 includes a frame 28 extending beyond the spout opening 22 to overly the pin opening 26. The spout cap 24 further includes a mounting pin 30 extending outward from the frame 28 and sized to be received in the pin opening 26. As may be seen, the mounting pin 30 may thus restrict movement of the spout cap 24 into oscillation or rotation about the axis of mounting pin 30 and thus allow movement between the open and closed configurations.
While the frame 28 could simply overly the spout opening 22 to define the closed configuration, in the preferred embodiment the spout cap 24 is sized to be closely received within the spout opening 22. More preferably, the spout cap 24, frame 28 and mounting pin 30 are all formed monolithically from an elastic material (such as silicone). In this way the spout cap could deform to elastically seal within the interior of spout opening 22 in the closed configuration as shown in
The cover 14 further includes a vent opening 32 spaced from the spout opening 22 in the direction towards the center of cover 14. This spacing in this direction is intended to raise the vent opening above the level of liquid as it is being dispensed by tipping of the tumbler body 12. In the preferred embodiment shown, the spout opening 22, pin opening 26 and vent opening 32 spaced along a straight line, with the pin opening 26 being interposed between the other two openings. It is also possible for the pin opening 26 to be located at the center point of the cover 14, as shown.
The main object of the present invention is to shield the vent opening 32. To this end, a vent shield 34 extends outward from the frame 28 so as to overly the vent opening 32 when the spout cap is in the closed configuration. Vent shield 34 takes the form of a cantilevered element, and may be spaced slightly from the vent opening 32. As may be envisioned, any spray exiting the vent opening 32 would impinge upon the vent shield 34 and be blocked from further outward travel. The liquid portion of the spray would either be redirected to the upper surface of the cover 14, not toward the user. While not required, it is preferred to have the vent shield 34 spaced from the vent opening 32. This spacing would allow the spray to exit safely, and thus reduce any pressure within the tumbler 10, eliminating any problems when the user manually opens the spout cap 24.
As a further feature, it is preferred that the upper surface of the cover 14 include a funnel depression 36 centered upon the vent opening 32. As noted, the liquid portion of any spray will be redirected toward the upper surface of the cover 14. The funnel depression 36 will direct any such liquid to flow by gravity to the vent opening 32 to thus reenter the tumbler body 12.
From the foregoing it will be seen that this invention is one well adapted to attain all ends and objects set forth above together with the other advantages which are inherent within its structure.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
Since many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth of shown in the accompanying drawings is to be interpreted as illustrative, and not in a limiting sense.
