Description

[Detailed Description of the Invention] Technical Field This invention relates to a latch device for sealed bottles.

Prior Art A latching device for a sealed bottle includes: an annular band fitted into an annular groove in the neck of a bottle body; a lid support member rotatably attached to the band; and a lid supporting member attached to the band. It is generally comprised of a tightening lever that locks the lid support and presses the lid of the bottle supported by the lid support onto the bottle body. As this type of latching device, there are Utility Model 17262, Utility Model 53-157050, Utility Model 53-157051, etc., but the straps of these latching devices are elongated as shown in Figure 5. A strip-shaped strap 41 is bent and protruded in a U-shape at its center to provide a mounting portion 41a, and is further formed into an annular shape to fit into an annular groove provided at the neck of the bottle body. I had become able to do it. Furthermore, both ends 4
1b were bent outwards from each other and extended parallel to each other.

Problems that the invention is intended to solve However, in order to form this metal band, it is necessary to bend the mounting portion 41a of the metal band 41 into a U-shape as described above, and to form the entire band into an approximately ring shape. Although this can be done automatically with a high-quality automatic forming machine, it is not simple, and this type of automatic forming machine also has the disadvantage of being expensive.

Furthermore, as in the conventional example shown in FIG.
An M in which a connecting fitting 42 having engagement holes 42a is fitted on both sides of the end 41b of the M, or an M in which both ends are bent inward as in the conventional example shown in FIG.
The one in which the letter-shaped connecting fittings 46 are engaged with both ends 41b of the band plate 41 is used when tightening the lid (not shown) with the tightening lever 44.
When the caps move away from each other, they do not return and the strip plate 41 lifts up from the annular groove (not shown) in the bottle body, resulting in a disadvantage that the adhesion of the lid to the bottle body becomes weak. .

Purpose The purpose of this invention is to eliminate the above-mentioned drawbacks,
By forming the band with a pair of band plates, the forming of the band plate can be automated extremely easily, and by attaching tension springs to both opposing ends, the lid can be tightened even when the bottle body of the lid is tightened. An object of the present invention is to provide a latching device for a sealed bottle that can maintain close contact with the bottle.
