1. Field of the Invention
-
This invention relates to a lid of a canteen, particularly to one having a drinking spout removing from a cap without being touched, enabling a user to drink liquid in the canteen conveniently and hygienically.
-
2. Description of the Prior Art
-
Commonly, in order to prevent liquid (such as water, juices or beverages) slopping when a canteen is tilted, a lid is employed to close or screw up with an opening of the canteen. When a user is to drink the liquid in the canteen, he (she) has to take off the lid first before drinking, not so convenient in use. Thus, as shown in FIGS. 1 and 2, an improved conventional lid with a drinking spout has been devised to overcome the defect mentioned previously. It is provided with a cap 10 and a drinking spout 13. Deeply cut in a top of the cap 10 is a recess 11 that is provided with an exit 110 bored in the bottom and a pivotal hole 111 formed in two sidewalls respectively. A groove 12 is also dug in the top of the cap 10 to communicate with the recess 11, with a depth shorter than that of the recess 11. An air hole 120 is bored in the bottom of the groove 12. The drinking spout 13 is pivotally engaged with the recess 11, provided with a passage 130, a revolving portion 131 formed at a lower end, a pivotal projection 132 formed at two sides of the revolving portion 131 respectively, and a blocking bar 133 projected from one sidewall for being correspondingly inserted in the air hole 120. The lid is used to close up a main body 14, with the exit 110 connected with a straw 15. When a user is to drink the liquid in the main body 14, he (she) needs to use a finger touching a free end of the drinking spout 13 to push it up. By the time, with the pivotal projections 132 functioning as an axis, the drinking spout 13 is removed from the groove 12 of the cap 10, with the passage 130 of the drinking spout 13 exactly corresponding to the exit 110 in the recess 11 of the cap 10. Then the liquid in the main body 14 can be drank out through the drinking spout 13. However, using a finger to directly touch and push the drinking spout 13 can aptly contaminate the drinking spout 13 by bacteria on the finger, possible to affect health. Moreover, the drinking spout 13 is also easy to be contaminated and dusted as it is exposed to the air without any protection.

The drinking spout 3 is pivotally set in the accommodating groove 200 of the pivotal base 20, provided with a lengthwise passage 30, a walking projection 31 and a pivotal projection 32 extended from two sidewalls respectively, and a waterproof washer 33 installed in the recess 202.
-
The pulling member 4 is pivotally installed on the pivotal base 20, provided with a pivotal ear 40 formed at two sides of the bottom respectively, a pivotal hole 41 bored in each of the pivotal ears 40 for being inserted with a pivot 410, and a sliding groove 42 cut in two corresponding sides respectively. A first notch 43 is formed at the bottom of each of the sliding grooves 42 and a second notch 44 is formed at the top of each of the sliding grooves 42. The bottom surface of the second notch 44 is formed inclined. The pulling member 4 is additionally provided with a round concave 45 formed at two corresponding outside walls respectively, and a lateral fixing ridge 46 formed at the top inner wall to engage with the engagement slot 271 of the pivotal base 20.
-
The pressing member 5 is assembled in the opening 24 of the pivotal base 20, provided with a locking member 50 located at the top to engage with the engaging groove 25 of the locking portion 23, a through hole 51 bored in the bottom, a locking groove 52, a torsion spring 53, and a bolt 54 inserted in the bolt holes 260 of the pivotal ears 26, the torsion spring 53 and the through hole 51.
-
In assembling, as shown in FIGS. 3-5, the waterproof washer 33 is first put in the recess 202 of the pivotal base 20 of the cap 2 and then the drinking spout 3 is installed in the accommodating groove 200 of the pivotal base 20, with the pivotal connecting projections 32 respectively fitted in the positioning grooves 201 so that the drinking spout 3 is pivotally combined with the cap 2, able to be turned to stay in the accommodating groove 200. Next the pulling member 4 is pivotally connected with the connecting base 22, with the pivotal ears 40 outwardly attached to the connecting base 22 and the pivotal hole 220 of the pivotal ear 22 exactly aligned to the pivotal holes 41 of the pulling member 4. The pivot 410 is successively inserted in the pivotal hole 220 and the pivotal holes 41 so that the pulling member 4 is pivotally connected with the connecting base 22. The pulling member 4 can be swayed to get close to the drinking spout 3 to enable the walking projections 31 to move through the second notches 44 to move into the sliding grooves 42, as shown in FIG. 10, so that the pulling member 4 can cover on the drinking spout 3, as shown in FIG. 5. The fixing projection 46 of the pulling member 4 is next forced slightly to lock in the engagement slot 271 of the recessed notch 27, making the pulling member 4 positioned on the pivotal base 20 of the cap 2. Then the torsion spring 53 is established between the pivotal ears 26 of the pivotal base 20, with one end resting on the upper surface of the cap 2. The pressing member 5 is placed in the opening 24 under the locking portion 23 of the pivotal base 20, with the torsion spring 53 attaching on one side of the pressing member 5 to correspond to the through hole 51 of the pressing member 5 and having another end confined in the locking groove 52 of the pressing member. Finally the bolt 54 is inserted through the bolt holes 260 of the pivotal ears 26 and the through hole 51, with the locking portion 50 of the pressing member 5 engaged with the engaging groove 25 of the locking portion 23, making the pressing member 5 fixed with the pivotal base 20. Thus, the assembly of the lid is finished.
-
In using, as shown in FIGS. 5˜10, the cap 2 is first screwed together with a canteen body 60 and a straw 61 is jointed with the projecting bar 21 of the cap 2 to extend down to the bottom of the canteen body 60. When a user wants to drink liquid (water, juice or beverages) in the canteen body 60, he (she) just needs to keep fingers holding the round concaves 45 at two sides of the pulling member 4 to outwardly pull the upper portion of the pulling member 4. While the pulling member 4 is pulled outwards, with the pivot 410 used as an axis, the drinking spout 3 is to be spontaneously moved owing to the walking projections 31 restricted in the sliding grooves 42. And as shown in FIG. 6, the drinking spout 3 is to outward by means of the pivotal projections 32 functioning as axes. As the drinking spout 3 is driven by the pulling member 4 to contact the inclined surface 221 of the connecting base 22, it is to stop moving, with the bottom of the passage 30 of the drinking spout 3 facing the through hole 210 of the cap 2, as shown in FIG. 7. Then the pulling member 4 is further pulled down to force the walking projections 31 to move out of the first notches 43, enabling the drinking spout 3 freed from the pulling member 4 so that the pulling member 4 can move down further by itself independent from the drinking spout 3, as shown in FIG. 8. By the time, a user can start drinking the liquid flowing through the straw from the canteen body 60 by using the drinking spout 3. According to the processes described above, the drinking spout 3 can be properly positioned for a user to drink without being touched by fingers. On the contrary, if the drinking spout 3 is to be stored, pushing the pulling member 4 upward is the only job. When the pulling member 4 is pushed sufficiently close to the drinking spout 3, the walking projections 31 of the drinking spout 3 are to move through the first notches 43 into the sliding grooves 42 of the pulling member 4, as shown in FIG. 7. And the drinking spout 3 is to be driven by the pulling member 4 to move upward until being completely sheltered when the pulling member 4 is further pulled upwards, as shown in FIGS. 5 and 6. Thus, the drinking spout 3 is never to be touched no matter whether it is pulled out for drinking or sheltered for storing, used conveniently and hygienically.
-
Besides, It is to be noted that suppose the drinking spout 3 is incidentally pulled upward to rest in a stored status shown in FIG. 9, a user just needs to push the pulling member 4 toward the drinking spout 3 so as to enable the walking projections 31 to move from the second notches 44 into the sliding grooves 42, as shown in FIG. 10. The pulling member 4 can be also engaged with the pivotal base 20 to protect the drinking spout 3.
-
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
