Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a water storage container such as a pot.

(B) Prior art A water storage container for storing water, hot water, etc. is equipped with a lid that closes the opening of the container to prevent dirt from entering and to prevent the contents from suddenly leaking out when the main body falls over. Has a body. Additionally, this lid can keep hot water in the container.

By the way, a typical example of this type of water/hot water storage pot is the so-called jar-type pot, but it was
As in Publication No. 59-33309, the lid is pivoted to one side of the main body so that it can rotate freely, and when the lid is closed, the locking body provided on the lid side engages with the locking groove on the main body side. .

However, when opening the lid by rotating it,
The operation became troublesome because it required both hands to hold the knob of the lid with one hand and push the button for releasing the locking body with the other hand. In addition, when removing the lid, it is difficult to remove the pivot, and the pivot pin on the lid that makes up the pivot may break, or the pivot base that locks the pivot pin may be deformed or broken. There was a drawback.

(c) Problems to be solved by the invention The object of the invention is to configure the lid covering the opening of the container to be detachable and to allow the lid to be easily attached and detached with one hand.

(d) Means for solving the problem The present invention provides a frame, a container, a frame cover that fixes the upper periphery of the frame and the periphery of the opening of the container, and a lid that has a knob and covers the opening of the container. A button that constantly protrudes outward from the side wall of the knob due to a plurality of engagement grooves and springs provided at appropriate positions on the inner wall of the frame cover, and a lock that protrudes from the outer wall of the lid body in conjunction with the button. The structure includes a locking device consisting of a stop protrusion.

(E) Function When removing the lid, hold the knob while pressing the button with one hand, resist the spring to remove the locking protrusion from the engagement groove, and then lift the knob to remove it.

(f) Embodiments Examples of the present invention will be described based on the drawings. 1
2 is a cylindrical frame; 2 is a bottomed cylindrical container housed and fixed inside the frame; and a flange 4 extending outward from the periphery of an upper opening 3 is provided.
Reference numeral 5 denotes a ring-shaped frame cover made of synthetic resin that fits the upper peripheral edge of the frame 1 and the lower surface of the flange 4 to fix the frame 1 and the container 2, and has a plurality of engagement grooves on the opposing inner walls, respectively. 6, 6, 6,
6 is provided with an engagement recess 7 on one side. Reference numeral 8 denotes a lid body that is housed inside the frame cover 5 and covers the opening 3 of the container 2, and includes an upper plate 10 integrally molded with a hollow knob 9 projecting upward at the center of the upper surface, and a lower part of the upper plate. A lower plate 1 is fixed to the upper plate to form a space 11 therebetween and has a positioning protrusion 12 on one side.
3 and an inner lid 14 which is detachably attached below the lower plate. The inner lid 14 is provided with an engaging rod 15 projecting upwardly at the center of its upper surface, and a ring-shaped packing 16 is fitted and fixed on the outer peripheral edge. 17 is a rubber bushing fitted and fixed to the center of the lower plate 13; 18, 18 are insertion holes drilled in the side wall of the knob 9; 19, 19, 19, 19;
20 is a support plate screwed and fixed to the lower surface of the upper plate 10, and each includes a plurality of parallel guide pieces 21, 21. , 21, 21 are integrally molded. 22, 22 are a pair of operating bodies housed in the space 11, and inside there are a plurality of pins 23, 23,
23, 23 and the insertion hole 18 located inside the knob 9,
Buttons 24, 24 protruding from 18 and the insertion hole 1
9, 19, 19, 19, and the lower surface of the tip side is tapered downward from the outside to the inside.
A plurality of locking protrusions 26, 26, 26, 26 having numbers 5, 25, 25, 25 are integrally molded. 2
7, 27 are the guide pieces 21, 21, 21, 21
The pins 23, 23, 23, 2 are arranged in between and at both ends.
3 is inserted to urge the buttons 24, 24 to protrude outward from the side wall of the knob 9 and the locking protrusions 26, 26, 26, 26 to protrude from the outer wall of the lid body 8. are doing.

In this way, the engagement grooves 6, 6, 6, 6 and the operating body 2
2, 22 and springs 27, 27 are the locking device 2.
8.

Next, we will discuss the operation. When removing the lid 8 to fill water into the container 2, press the button 24 with one hand.
24 is pressed inward against the springs 27, 27, the locking protrusions 26, 26, 26, 26 are disengaged from the engagement grooves 6, 6, 6, 6, and the knob 9 is lifted up in that state.

When attaching the lid 8, place the protrusion 12 of the lid 8 into the engagement recess 7 of the frame cover 5, and store it inside the frame cover 5 while pushing the buttons 24, 24 inward with one hand. , After storing, press button 24,
When released from 24, the locking protrusions 26, 26, 26, 26
are projected by the springs 27, 27 and engaged with the engagement grooves 6, 6, 6, 6. In this engaged state, the center portion of the inner lid 14 is pressed down by the rubber bushing 17, and this pressing force causes the inner lid 14 to be pushed down.
Packing 16 on the outer peripheral edge of flange 4 is in close contact with the upper surface of flange 4. Therefore, the upper plate 10 and the lower plate 13 are pushed up by the elastic force of the packing 16 and the elastic force of the rubber bushing 17, and the upper surfaces of the locking protrusions 26, 26, 26, 26 and the engagement groove 6,
The upper portions of the inner walls of 6, 6, and 6 abut and are securely engaged.

The taper of the locking protrusion is such that when the lid is housed in the frame cover without sufficiently pressing the button, the operating body comes into contact with the inner wall of the frame cover and moves the operating body inward.

(g) Effects of the device As described above, the present invention provides a button inside the lid that always projects outward from the side wall of the knob, and a locking protrusion that projects from the outside wall of the lid in conjunction with the button. When closing the opening of the container, the locking protrusion engages with the engagement groove provided on the inner wall of the frame cover, so hold the knob with one hand to ensure that the locking protrusion and the engagement groove The lid can be removed by uncoupling it and lifting it up. In addition, compared to the conventional case in which the lid is rotatably supported on the main body, it is easier to attach and detach, and there is no chance of the pivot being broken. Furthermore, because the locking protrusion is provided on the lid and the engagement groove is provided on the frame cover, there is no protruding part on the main body side, which is cleaned most often, making cleaning easier, and the locking protrusion engages with the frame cover. Therefore, there is no thermal deformation as it is separated from containers that reach high temperatures like water heaters. Further, since the lid body is maintained in the closed state by the engagement between the plurality of engagement grooves and the locking protrusions, no rattling occurs after the lid is closed.
