Description

[Detailed explanation of the invention] (a) Field of application This invention is designed to prevent the intrusion of foreign matter such as flies, aphids, and dust into the dispensing channel of a pot that keeps cooling water or hot water cold or hot when it is not in use after dispensing the liquid. The present invention relates to a lid opening/closing mechanism that prevents.

(b) Prior art The conventionally used lid opening/closing mechanism for the spout channel is a lid opening/closing mechanism using the lid's own weight, a lid opening/closing mechanism using a weight attached to the lid, or a lid opening/closing mechanism that uses a weight attached to the lid, or a lid opening/closing mechanism that moves the lid up and down when the stopper is screwed. There are two types of lid opening/closing mechanism: a lid opening/closing mechanism based on a dimensional difference, and a lid opening/closing mechanism based on a horizontal dimensional difference using an eccentric cam formed at the upper end of the plug.

However, the lid opening/closing mechanism using the lid's own weight and the lid opening/closing mechanism using a weight attached to the lid are simple, but the opening/closing operation depends on parts with small mass, so the operation is difficult. It is slow and unreliable, and is now not widely used.

In addition, the lid opening/closing mechanism is based on the vertical dimension difference when the plug is screwed on, and the lid opening/closing mechanism is based on the horizontal dimension difference created by an eccentric cam formed at the top end of the plug, which operate quickly and reliably. Therefore, this mechanism is currently used in most cases. However, in this mechanism, when converting the linear motion of the stopper into the rotational motion of the lid, the conversion is always done via a converter, and the mechanism is complicated.

(c) Purpose of the invention Therefore, this invention allows the rotational movement of the stopper to be directly actuated by the rotational movement of the lid, allowing the lid to open and close quickly and reliably without using a converter, and to perform the operation smoothly. The object of the present invention is to provide a lid opening/closing mechanism for a pot spouting path, which has a simplified mechanism.

(d) Structure of the device A pot comprising a spout having a communicating spout at the mouth of a thermos bottle and a spout having a spout forming a spout for guiding the liquid poured out from the spout to the outside. In the step, a spiral strip of the cap is screwed onto a spiral strip of the mouthpiece so that the cap for opening and closing the spout is movable in the vertical direction, and a lid for closing the tip of the spout is provided. It is rotatably biased in the opening direction and pivotally attached to the mouthpiece, and when the spout is closed at the bottom of the stopper, an operating projection is provided at the top of the stopper at a position corresponding to the operating part of the lid. a piece is provided to appropriately protrude from the spiral strip, and the operating portion at the rear end of the lid body has a circumferential surface with the same radius of rotation as the operating protrusion piece of the plug body;
Furthermore, the lid opening/closing mechanism of the pot dispensing channel is characterized in that an attacking surface is formed on the entry side of the operating protrusion of the plug, and the lid is closed by rotation of the plug in the closing direction.

(e) Effects of the invention According to this invention, the rotational movement of the stopper is directly activated by the rotational movement of the lid, so that the lid can be opened and closed quickly and reliably without using a converter, and the operation can be performed smoothly. Because the mechanism is capable of
To provide a clean product that is inexpensive, durable, and can forever prevent the intrusion of foreign substances such as flies, oilseeds, and dust.

(F) Embodiment of the invention An embodiment of the invention will be described in detail below based on the drawings.

The drawing shows the lid opening/closing mechanism of the pot spouting channel, and in FIG. A spouting passage 5 for guiding the discharged liquid to the outside of the pot 4 is integrally and continuously protruded from the outer circumferential wall and the bottom of the bottomed cylinder.

In addition, the mouthpiece 1 has a heat insulating bottle 6 attached to the bottom of its inner circumferential wall.
A spout 3 communicating with the spout 7 is bored, and a spiral strip 9 is provided on the inner circumferential wall of the spout 3 to open and close the spout 3 by vertical movement when the plug 8 is screwed and rotated. A small diameter portion 10 with a screw threaded thereon, and a large diameter portion 12 for storing (loosely fitting) the operating protrusion 11 formed on the top of the plug 8 in the inner circumferential wall when the spout 3 is closed with the plug 8. are provided for each.

On both sides of the rear upper end of the spouting channel 5, there is a lid body 1 which will be described later.
Lid body pivoting protrusion 1 for rotatably pivoting 3
4, 14 and spring mounting protrusions 16, 1 for mounting a spring 15 that always urges the lid body 13 toward the open side.
6 are provided protruding from each.

The stopper 8 has a spiral strip 17 on its circumferential surface, and when the spout 3 is closed at the bottom of the stopper 8, the stopper 8
An actuating protrusion 11 is provided at the upper part of the cover body 13 at a position corresponding to the actuating portion 18 so as to appropriately protrude from the spiral strip 17. In addition, since the actuating protrusion 11 of the stopper 8 is provided so as to appropriately protrude from the spiral strip 17 of the stopper 8, when the stopper 8 is rotated in the closing direction, the helical thread 17 of the stopper 8 is moved from the operating surface of the cover 13. 18 will not be interfered with.

The lid 13 has an L-shaped front end and is disposed to cover the spouting path 5 from an upper position of the spouting path 5. In addition, the lid body 13 has lid pivot holes 19, 19 protruding from both sides of the rear end, which are rotatably pivoted to the lid pivot attachment protrusions 14, 14 of the spouting channel 5, and spring mounting protrusions are inserted from below. Spring 15 attached to 16, 16
is always biased toward the open side.

The opening/closing operation of the lid 13 is controlled by the engagement and disengagement of the actuating portion 18 of the lid 13 and the actuating protrusion 11 of the stopper 8.
That is, when the stopper 8 is moved upward or removed, the operating portion 18 of the cover 13 and the actuating protrusion 11 of the stopper 8 are disengaged from each other as shown in FIG. The body 13 is rotated about the lid pivot holes 14, 14 to the open state by the bias of the spring 15. Therefore, the tip of the lid body 13 is opened, and the operating portion 18 at the rear end moves toward the center of the mouthpiece 1.

As shown in FIG. 3, the operating portion 18 at the rear end of the lid body 13 has a circumferential surface with the same radius as the rotation radius of the operating protrusion 11 of the plug body 8. , forming an attacking surface 20 for smoothly engaging them.

To use the pot 4 configured as described above, pour the object to be kept warm into the pot 4 and rotate the stopper 8 in the closing direction. The actuating protrusion 11 is received by the receiving surface 20 of the actuating portion 18 of the lid body 13 and enters the engaged state.

Furthermore, due to the rotation of the plug body 8, the operating protrusion 1 of the plug body 8
1 also presses the actuating part 18 of the lid 13 against the spring 15, rotates the lid 13 in the closing direction, and opens the spouting path 5.
This state is maintained until the spout 3 is completely closed.

As described in detail above, the pot dispensing channel lid opening/closing mechanism of the present invention instantly and reliably closes the dispensing channel 5 immediately before closing the stopper 8 and spout 3 to prevent the intrusion of foreign matter such as flies, oilseeds, and dust. It is possible to provide products that are preventive, hygienic, and inexpensive.
