Description

[Detailed description of the invention] Industrial field of application The present invention involves screwing a convex threaded part onto a concave threaded part fixed to the outer case using a fixing fitting, and fixing the container using this convex threaded part. This relates to fixing fittings for thermos flasks, etc.

Conventional technology Conventionally, when it comes to fixing containers such as thermos flasks, Jikkosho
47-9731 using a bottom cover and an inner bottle holder, or by notches provided in the fixing metal fittings 21 on both sides of the winding part 7 of the outer case 6 as shown in FIGS. 4 and 5. There was something that hit the hook part 23.

Problems that the invention aims to solve: However, in the case of the former, high processing precision is required for the bottom cover and the inner bottle holder, and the structure is complex.
In addition, in the case of the latter, since the metal plate on either the left or right side of the winding part 7 winds up the other metal plate, the winding part 7 has a gentle step on the riding side, and a right angle on the winding side. A step occurs, and the edge 24 of the hook 23
Because it was slippery and could not be fixed on the riding side, it was fixed only on the winding side, so when fixing the container through the concave screw part 5, it could only be fixed against the force from either the left or right side where the convex screw part pushes up the container. First, it is very inconvenient when attaching or removing containers, etc., and there are also disadvantages in that attachment or detachment becomes impossible.

Means for Solving the Problems The present invention has been made to eliminate the above-mentioned drawbacks, and the object is to provide a fixing fitting that is simple in structure and that can reliably attach and detach containers. For this purpose, two hooks are provided on the fixing metal fitting, one at the top and one at the bottom. It is designed so that it can be fixed to the fixing fitting even by rotation of the holder.

By doing this, the fixing bracket can be easily attached to the outer case and can be fixed against both left and right forces on the concave threaded part, allowing the convex threaded part to rotate without any hindrance. It is.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The configuration of this embodiment is as shown in FIGS. 1, 2, and 3. In the figure, 1 is a container such as a thermos flask, which is abutted against a mouth part 3 through a gasket 2 at the upper part and supported by an outer case 6 through a convex screw part 4 and a concave screw part 5 at the lower part. It has the following. The outer case 6 is made by rolling one metal plate into a cylindrical shape and then rolling one metal plate around the other metal plate to form a rolled part 7 and joining them as shown in FIG. It is something that exists. Also, on either the left or right side of the winding part 7, one metal plate forms a gentle step that rides on the other metal plate, and on the other side, one metal plate rides on the other metal plate. It is a wrap-around, forming a right-angled step. Reference numeral 8 denotes a groove, which is formed over the entire circumference of the bottom of the container 1, and is a portion where the upper convex portion 10 of the convex screw component 4 abuts over the entire circumference to push the container 1 upward. A convex screw 11 is provided all around the circumference of the convex screw component 4, and this convex screw 11 is a part that is screwed into the concave screw 12 of the concave screw component 5. Reference numeral 13 denotes a bottom curled portion, which is provided at the lower end of the inside of the outer case 6, on which the concave threaded part 5 is attached and is pressed down by the downward force from the convex threaded part 4 and the container 1. Reference numeral 14 denotes a convex portion, which is provided on the concave screw component 5, and a convex portion 2 provided on a flat plate-shaped fixing metal fitting 16 that is attached to the outer case 6 with a mounting screw 15.
This is a portion that fits between the cut and raised portions 17. 1
Reference numeral 8 denotes hook portions, which are formed by cutting and bending at two locations above and below the mounting screw 15 in the fixing fitting 16, and the edge portion 19 at the tip of the hook portion 18 is
It has a configuration in which it abuts against a stepped portion of the winding side 20 having a right-angled step of the outer case 6.

Next, the effects of this embodiment will be described.

Container 1 using fixture 16 according to this embodiment
For fixing, first rotate the convex screw part 4 and push up the container 1 until the seal 2 of the upper mouth part 3 joins the container 1 in a watertight manner. At this time, the concave screw component 5 to which the convex screw component 4 is rotated tries to rotate together with the convex screw component 4, but the convex portion 14 of the convex screw component 5
Because it fits into the cut and raised part 17 of the fixing metal fitting 16, the edge part 1 at the tip of the hooking part 18 of the fixing metal fitting 16
9 is abutted against the winding portion 7 of the outer case 6 which has a step at a right angle. Furthermore, since a mounting screw 15 is provided between the hook portions 18 and the fixing bracket 16 is fixed to the outer case 6, the upper hook portion of the concave screw component 5 cannot be rotated to the right. By 18,
With respect to rotation to the left, the hook portions 18 at the lower portions are in a fixed state, and the concave threaded part 5 does not rotate with the rotation of the convex threaded part 4.

Effects of the invention As described above, according to the invention, the upper and lower two hooks provided on the fixing bracket are provided on the winding side of the winding part of the outer case, which has a step at right angles. The parts do not move all at once when the convex screw part is rotated to the left or right, and the container can be reliably installed and removed, making it easy to assemble and repair thermos bottles, etc. , an extremely large effect can be expected.
