In this case, it is excellent in that it is locked in the engaged state and does not come off unexpectedly, but the mechanical resistance when engaging and disengaging the elastic engagement piece or engager from the protrusion or groove is large, and It is cumbersome to operate.

The present invention solves such conventional problems and also
The purpose is to provide sufficient attachment that will not come off unexpectedly, even without using a lock.

``Means for Solving the Problems'' In the present invention, an inner cap 31 and an outer cap 32 are fitted vertically and slidably, and the inner cap 31 has a short peripheral wall 313 hanging from the periphery of the top wall 311.
At the same time, a plurality of elastic engagement pieces 314 that engage with the engagement protrusions 14 of the bottle neck 13 are hung from the peripheral wall so as to be elastically deformable in bending, and further tongues are provided from these elastic engagement pieces. The outer cap 32 is provided with a long circumferential wall 322 that extends further downward from the lower end of each of the tongue pieces 315 from the periphery of the top wall 321, and the outer cap 32 is connected to the inner cap. At the same time, each elastic engagement piece 314 and each tongue piece 31 are fitted to the outside of the peripheral wall 313 so as to be vertically slidable.
Furthermore, the upper end of each of the tongue pieces 3 is loosely fitted on the outside of the outer cap 32, and the upper end is fitted inside the lower end of the peripheral wall 322 of the outer cap 32.
A guide tube inserted into the lower end of 15 is provided,
The lower end of the guide cylinder is supported by the lower end of the peripheral wall 322 of the outer cap via a flange 331, and a floating ring 34 is provided on the outer periphery of the guide cylinder, the upper edge of which is formed into a tapered surface 341 corresponding to the lower end of each tongue piece 315. It is characterized by being equipped so that it can be slid up and down.

``Function'' With the above structure, when initially attaching the cap 3 to the neck of the bottle, it is sufficient to place the cap 3 over the bottle neck 11 and push down the outer cap 32, which allows the entire cap to be attached. Descend and
Each elastic engagement piece 314 of the inner cap 31 rides over and engages with the engagement protrusion 14 of the bottle neck 13, and at the same time,
Among them, a cap 31 closes the bottle opening 11.

Next, when removing the cap 3, it is sufficient to pull the outer cap 32 upwards, and as a result, the floating ring 34 slides into the inside of each tongue piece 315 of the inner cap 31 with the tapered surface 341, and each tongue piece is removed. 315, and therefore each elastic engagement piece 3
Each tongue piece 315 and the elastic engagement piece 314 are pushed outward against the elastic force of the inner cap 31 , and each elastic engagement piece is disengaged from the engagement protrusion 14 . also rises, and the whole body passes upward.

The second and subsequent installations of the cap 3 can be done in the same way as the first time, but from the second time onwards,
At the time of removal, the floating ring 34 fits into each tongue piece 315 as described above, and each elastic engagement piece 314 opens outward together with each tongue piece, so that the cap 3 is fitted without resistance and continues. By pushing down the outer cap 32, the floating ring 34 comes out downward from each tongue piece 315 and is released from the restraint, and each elastic engagement piece 3
Each tongue piece 315 and each elastic engagement piece 314 return inward due to the elasticity of 14, and each elastic engagement piece engages with the engagement protrusion 14 of the bottle neck 13 to ensure the attached state. , the inner cap 31 closes the bottle opening 11.

"Example" The illustrated embodiment will be described below.

In the figure, 1 is a bottle, 2 is a spouting stopper fitted to the mouth of the bottle, and 3 is a cap detachably attached to the mouth of the bottle, and these are made of synthetic resin as appropriate.

The bottle 1 has an engaging groove 12 around the outer periphery of the mouth 11, a neck 13 connected to the mouth, which has a slightly larger diameter and is relatively long, and has a neck 13 on the outer periphery of the upper end of the neck. An engaging protrusion 14 is provided around the periphery.

The pouring stopper 2 has inner and outer peripheral walls 2 on the peripheral edge of the top wall 21.
2 and 23, and the inner and outer peripheral walls are connected to the mouth part 11.
The inner edge of the outer peripheral wall 23 is connected to the engaging edge 2.
4, which is engaged with the engagement groove 12 on the outer periphery of the mouth, and a spout 25 is bored in the center of the top wall 21.

Cap 3 has an inner cap 31 and an outer cap 3.
2 so that they can slide vertically, and the inner cap 31
In this method, a protrusion 312 that fits with the spout 25 is protruded from the center of the inner surface of the top wall 311, and an extremely short circumferential wall 313 is provided hanging from the periphery of the top wall 311, and the outer edge of the circumferential wall is formed into a protruding edge. , a plurality of elastic engagement pieces 314 that engage with the engagement protrusion 14 of the bottle neck 13 are hung from the lower surface of the peripheral wall excluding the protruding edge so as to be elastically deformable in bending, and from the lower end of these elastic engagement pieces Further, a tongue piece 315 with meat removed inside is vertically provided, and
The outer cap 32 is provided with a long circumferential wall 322 that extends further downward from the periphery of the top wall 321 than the lower ends of the respective tongues 315, and the outer cap 32 is provided with a long circumferential wall 322 that extends further downward from the lower end of each of the tongues 315.
13 in a slidable manner, and at the same time, it is loosely fitted to the outside of each of the elastic engagement pieces 314 and the tongue pieces 315.

Furthermore, a short guide tube is provided inside the lower end of the peripheral wall 322 of the outer cap 32, the upper end of which is inserted into the lower end of each tongue piece 315, and the guide tube is integrally protruded from the lower end of the guide tube. A floating ring 34 is fitted and supported on the lower end of the peripheral wall 322 of the outer cap via a flange 331, and has an upper edge formed in a tapered surface 341 corresponding to the lower end of each tongue piece 315 on the outer periphery of the guide cylinder.
A stopper 332 for preventing the floating ring from coming off is provided on the outer edge of the upper end of the guide cylinder. Note that the floating ring 34 is forced to fit over the stopper 332.

This structure is similar to the above, and produces the above-mentioned effect, but in this case, in particular, when attaching the cap 3, the protrusion 312 hanging down from the top wall 311 of the inner cap 31 fits into the bottle opening 11. The spout 25 is fitted into the spout 25 of the spout tap 2 to close it.

Also, when attaching the cap 3 for the second time and thereafter, the stopper 33 provided at the upper end of the guide tube 33
2 pushes down the floating ring 34 fitted in each tongue piece 315 as the outer cap 32 descends.

Note that the inner cap 31 is prevented from coming off by a flange 331 of the guide tube 33.

"Effect of the invention" According to the invention, when removing the cap 3,
It is sufficient to simply pull the outer cap 32 upward, and as a result, the floating ring 34 fits into each tongue piece 315 of the inner cap 31 and opens each tongue piece and each elastic engagement piece 314, so that each elastic The engaging piece 314 can be disengaged from the engaging protrusion 14 of the bottle neck 13 with almost no mechanical resistance, and can be removed very easily with a single operation.

Also, the cap 3 removed in this way
When reattaching the bottle, simply place the cap 3 over the bottle opening 11 and push down the outer cap 32. As a result, the floating ring 34 that was fitted inside each tongue piece 315 is pushed down. As each elastic engagement piece 314 returns inward by its own elasticity and engages with the engagement protrusion 14 of the bottle neck 13, this also occurs in a single operation with almost no mechanical resistance. It can be installed easily.

Therefore, the cap can be attached and detached very easily and easily with one hand and one touch by holding only the outer cap 32 and simply pulling it up or pushing it down, which is extremely convenient.

Furthermore, since each elastic engagement piece 314 is mechanically opened by fitting the floating ring 34, the elasticity of each elastic engagement piece 314 can be strengthened and strong engagement can be achieved.
Unexpected departures can be accurately eliminated.
