The tips of the end extension sections of the strap are processed to form a closed terminal. The strap can be selectively retracted back into the receiving space inside the cap.

TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to a strap receivable water kettle cap, and more particularly to a structure that provides a function of shoulder carrying water kettle and is capable of fast receiving the carrying strap in the kettle cap.

DESCRIPTION OF THE PRIOR ART

A water kettle is easy to carry and allows a user to drink water in any desired time and due to the drive resulting from rising of “green” spirit for environmental protection, people get more frequently carrying a water kettle to contain drinking water when they are going to school and work, do exercises, or even travelling. A conventional water kettle is provided with a carrying strap that allows a user to carry the water kettle with a hand or a shoulder for easy access. However, it is generally impossible for shoulder carrying of water kettle if a user is doing certain activities, such as cycling, mountain climbing, and rock climbing; or in cases where the user wishes to place the water kettle in a side pocket of a backpack, the carrying strap becomes troublesome to the user. Although in some water kettles, the carrying strap is designed to attach to the kettle through releasable buckle, so that the strap, when not being used, can be easily removed from the kettle. However, such designs make the use of the water kettle inconvenient and may also cause undesired loss of the strap, or the strap may be simply left in home and cannot be used when the kettle user gets out. Apparently, the conventional strap of water kettle is not a perfect one and further improvements are needed.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a strap receivable water kettle cap, which allows fast retraction and concealment of a strap that is provided for shoulder carrying through an operation of rotating a rotary ring attached to a cap so as to realize fast retraction and storage and provide easy and practical use.

To achieve the above objective, the present invention provides a strap receivable water kettle cap, which comprises a cap that is coupleable to a water kettle, a rotary ring mounted to a bottom of the cap, and a strap. The cap has a side wall forming an elongate slot. The rotary ring has an upper portion forming a diameter reduced vertical wall. The vertical wall and the side wall of the cap form therebetween a receiving space. The vertical wall forms an extension and retention section, which structurally comprises at least two parallel slits to allow the strap to extend through parallel slits to be retained thereby. The strap is received in the receiving space and extends through the extension and retention section, and further extends through the slot formed in the side wall of the cap to have end extension sections of the strap projecting outside the cap. The end extension sections of the strap are processed to form a closed terminal. As such, a user may use the strap to carry the water kettle on his or her body. When the user does not need to carry the kettle, the rotary ring mounted to the bottom of the cap can be rotated to retract the strap back into and conceal in the receiving space of the cap to thereby realize fast retraction and storage of the strap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring toFIGS. 1-3, the present invention provides a strap receivable water kettle cap, which generally comprises a cap10, a rotary ring20that is attached to a bottom of the cap10, and a strap30.

The cap10is attachable to a kettle mouth41of a water kettle40. In the instant embodiment, the cap10forms therein an internal thread11(seeFIG. 2a) for direct threading engagement with the water kettle40of which the kettle mouth41forms a mateable external thread42. The cap10has a top forming a retention seat12and the retention seat12has a bottom forming a water outlet13extending therethrough. The retention seat12is structured to receive a suck nozzle50to attach thereto in such a way that the suck nozzle50has a central hole corresponding to the water outlet13to allow a suck of water by a user. The present invention further provides an elongate slot15that is formed through a side wall14of the cap10. The cap10has a bottom rim forming a raised rib16. The cap10forms coupling means on an inside surface of the side wall14, whereby the cap10is coupleable to the rotary ring20with the coupling means. In the embodiment illustrated, the coupling means comprises a plurality of pawls17, and the cap uses the pawls17to engage a coupling seat26that is formed on a lower edge of an inside surface of the rotary ring20. As shown inFIG. 2a, in the instant embodiment of the present invention, a connection wall18is formed between adjacent ones of the pawls17so that the pawls17may be reduced in vertical dimension but structurally strengthened. Further, the connection wall18and the side wall14may form therebetween a space for accommodating the strap.

In the embodiment illustrated, the rotary ring20has an upper portion forming a diameter reduced vertical wall21, and as shown in the drawings, the vertical wall is made in the form of a circle of circumferential wall. The vertical wall21forms therein an extension and retention section22. In the embodiment illustrated, the extension and retention section22comprises two parallel and spaced slits, whereby the strap30may be put through the two parallel slits with two ends to be retained thereby. The vertical wall21has a lower end where a recessed step23is formed. Formed in the step23is a groove24corresponding to the raised rib16of the cap10, whereby in assembling, the raised rib16is fit into the groove24and the pawls17of the cap10are set in engagement with the coupling seat26formed on the lower edge of the inside surface of the rotary ring20to couple them together (seeFIG. 3) in such a way that the cap10and the rotary ring20are relatively rotatable with respect to each other and the vertical wall21of the rotary ring20and the side wall14of the cap10form therebetween a receiving space A (seeFIG. 3). The receiving space A formed between the cap10and the rotary ring20is delimited by the side wall14and the vertical wall21. Alternatively, in other feasible embodiments that are not illustrated herein, the vertical wall21may not be set in the form of a full circle or in a closed form and, with the pawls17set in engagement with the coupling seat26of the cap10, the pawls17and the side wall14form therebetween a receiving space A, which may similarly serve as a space for receiving and accommodating the strap30therein. Further, the rotary ring20has an outer circumference forming a roughened section25for easy rotation of the rotary ring20. Further, the extension and retention section22may be alternatively structured to comprise more than two parallel slits, such as three or four slits, and this also allows the strap30to sequentially and curvedly extend through all the parallel slits to similarly achieve the result of securing an end of the strap.

In the embodiment illustrated, the vertical wall is set in the form of a full circle of circumferential wall21and the vertical wall forms the extension and retention section22, yet the vertical wall may alternatively be structured as an incomplete circle of circumferential wall and may comprise simply a short segment of vertical wall in which the extension and retention section22is formed. Under this arrangement, when the pawls17are put in engagement with the coupling seat26of the cap10, the pawls17can form a receiving space A with respect to the side wall14.

The strap30is received in the receiving space A defined between the cap10and the rotary ring20and extends through the slits of the extension and retention section22of the rotary ring20to have an inner terminal thereof retained thereby (seeFIG. 2b). The ends of the strap30are further put through the slot15formed in the side wall14of the cap10to allow end extension sections of the strap to extend outside the cap10. In the instant embodiment, tips of the end extension sections of the strap30are set outside the cap10and are folded over each other and sewn together to form a closed outer terminal, whereby the outer terminal provides a stopping function for the strap30for being blocked outside the slot15of the cap10. Further, in other embodiments, the tips of the strap30may alternatively be fixed with thermal pressing or bonded to decorative buckling member or pull tab, or female and male buttons respectively provided on ends.

Further, in practical use, the strap30can be withdrawn by just a small length to be sufficient to fit over the wrist of a user and may then be securely attached to the wrist by rotating the rotary ring20to retract and tighten the strap. This avoids the embarrassing situation that an excessive length of the strap makes it easily gets off the wrist.

Referring toFIGS. 4 and 5, to use the present invention, a user simply rotates the rotary ring20attached to the bottom of the cap10to retract and wind backward the strap30into the receiving space A inside the cap10for being concealed therein. On the other hand, to extend the strap30for shoulder carrying, a user simply pull the tips of the end extensions of the strap30to fast unwind the concealed strap30for being carried on the shoulder of the user.

In summary, the present invention provides the following advantages:

(1) The present invention allows the strap to be fast retracted for being concealed and stored or to be directly pulled off for use, so that the present invention eliminates the drawbacks of inconvenience of repeated mounting and removing a shoulder strap for the conventional water kettles.

(2) The present invention allows the strap to be stowed inside the cap so that the present invention effectively eliminates the potential concern of losing the strap.

(3) The present invention allows a use, in carrying the water kettle, to selectively take shoulder carrying of the water kettle or to simply stow the strap.

Apparently, the present invention actually achieves the desired objective by providing a strap receivable water kettle cap, which realizes the advantage of convenience of use and adaptive applications in different ways of use.
