The insertion part insertion groove 21 with 22 is formed.

As a fifth embodiment, the bottle cap 1 is composed of a side portion 3 and an upper surface portion 2, and the side portion 3 is provided with a pull handle 5 having a hole 4 in the side portion 3 as a connecting portion 6. 3 and a support part connecting surface 47 is formed on the supporting part 42 having the protrusion 43 with the cutting line 41 on both sides between the connecting part 6, and the supporting part 42 and the supporting part connecting surface. Reinforcing part insertion groove 25 having a reinforcing part catching groove 26 between the upper surface part 2 and the stopper upper surface part 24 is treated as a space part 44 in the side part 3 of the portion where the 47 is located. In the cutting and the upper surface portion (2) and the cutting portion 27 and the perforation portion 48, the cutting portion 27 is connected to the side cutting portion 28 formed on both sides of the connecting portion 6, The inner wall of the side portion (3) has a locking projection (32) on the outer wall of the locking jaw 29 and the stopper 31 and the insertion groove 30 is formed between the locking projection (29) and the circular projection (32).

In assembling the reinforcement part 49 with the locking ring projection 46 in the main body, the anti-counterfeiting frame 51 is provided in the reinforcing part 49 as the cutting ring 50 and the cutting ring 50 upward. It is formed.

As a sixth embodiment, in assembling the reinforcement part 52 in the reinforcement part insertion groove, the outer end face of the reinforcement part 52 is in close contact with the upper side of the cutout part 27 formed in the main body.

As a seventh embodiment, the protrusion 43 formed on the lower side of the support part 42 is formed to a length sufficient to cover the bottleneck upper surface exposed to the space 44 during assembly.

As an eighth embodiment, the space portion 44 formed in the side portion 3 is formed in the shape of a wide wedge, and the support portion 42 is connected to the upper surface and the pull ring portion, but the support portion 42 has a wider inner side than the outer side. It is. In the figure, reference numeral 100 is a bottleneck. Referring to the effects of the present invention made as described above are as follows. The bottle cap 1 configured as described above is covered with the upper portion of the bottleneck 100 in the state as shown in FIG. 3 when the upper portion of the bottle cap 1 is placed on the upper side of the inlet of the bottleneck 100. When applied, the stopper 16 is inserted into the bottleneck 100 and the locking jaw 12 is to be caught to the outside of the bottleneck 100.

At this time, the stopper 16 exhibits an artificial intelligence function in which the annular protrusion 18 is elastically contracted or closely adhered to the inner diameter of the bottleneck due to the sealing part 23 formed by the insertion part 14 made of a relatively strong material. Will be done.

In this way, the synthetic resin bottle cap is firstly pushed downward by the continuous series of mechanical devices, and the pull handle is in a straight line with the bottle cap side part 3. 7) This protrusion (8) is over and will not be returned to its original position as shown in Figure 4 to maintain a straight line up and down with the side of the bottle cap.

When removing the bottle cap as shown in Fig. 4, insert the finger into the hole 4 of the pull handle 5, and pull the pull handle upwards, so that the projection operator 7 of the pull handle 5 If the pulley 8 is pulled out of the protrusion 8 in this state and the pull handle is pulled upward, as shown by the dotted line, the side cutout part 11 and the cutout part 10 are cut off, and the stopper 16 from the side part 3 is partially integrated. When upwardly pulled, the stopper 16 portion is completely removed from the bottleneck.

Also, since the stopper 16 is made of a relatively soft soft resin, the plug 16 has excellent sealing properties. The bottom of the stopper 19 has a plurality of reinforcing parts 20. The contents of the stopper 16 are either carbonic acid or batanic acid. Regardless, there is no closed end where the plug top surface 19 swells or descends.

In another embodiment, the present invention is novel in terms of securing the pull handle 5, in which the lower end of the reinforcing portion 34 side 38 of the first sixth portion is adjacent to the connecting portion 6, and then the first method and the first method. When pressing the upper surface in the state in which the bottle cap (1) is located in the upper portion of the bottleneck (100), the pull portion (5) becomes the bottleneck (100) as the connecting portion (6) as shown in FIG. Will be attached to.

At the time of opening, when the pull handle 5 is lifted up, the side part 38 is raised while the cutting part 40 of the connection part 6 is cut off, and the side part cutting part 28 and the upper part cutting part 27 are pulled out more. Cut off the stopper 31 is to be separated from the bottleneck.

As a third embodiment (see FIGS. 8-10), when the bottle cap 1 is placed on the bottleneck 100 in the same state as in FIG. 10 (8), and the upper surface portion is pressed, the stopper 31 is inside the bottleneck. Being inserted into the locking jaw 29 is caught in the outer diameter of the bottleneck, at the same time the support portion 42 is raised up by the top of the bottleneck at the same time, the protrusion 43 is in this process much more like the ninth by the bottleneck The pull handle 5 naturally sticks to the bottleneck.

When opening, the support portion 42 is lifted up when the pull handle 5 is lifted up, and when the pull continues in this state, the side cutting portion 28 and the cutting portion 27 are cut off so that the stopper 31 is separated from the bottleneck. Will be.

As a fourth embodiment, similar to the third embodiment, but the singular point is excellent in sealing because the plug 16 is soft, which is close to the top of the bottleneck 100 in addition to the circular protrusion 18. It is because it adheres closely.

As a fifth embodiment, the peculiarity of the present invention is to satisfy the structure of the mold in order to show the hook shape of the locking jaw 29, and the perforated part 48 is formed in the upper surface part 2. In this relationship, the bottle cap 1 is firmly fixed to the bottleneck 100, and the reinforcement 49 is upper part of the bottle cap 1 to protect the perforation part 48 formed for the shape of the hooking jaw 29. I covered it.

When the bottle cap 1 is covered in the same state as in FIG. 13, the bottle cap 1 is placed on the bottleneck 100 and then pressed, and the cap 31 is inserted into the bottleneck and simultaneously caught. (29) is also caught on the outer diameter of the bottleneck, at this time the hook portion of the locking jaw 29 is contracted contractively and is in close contact with the outer diameter of the bottleneck.

In addition, as shown in FIG. 15, the pull handle 5 has the support part connecting surface 47 also made by the support part 42 as shown in FIG. 15 in the process of the protrusion 43 being upward and upward by the upper end of the bottleneck. At this time, the pull handle 5 is an angle located in the bottleneck, depending on the protruding area of the protrusion 43.

When opening, the pull handle 5 is pulled out, and then the side cutout 28 is cut first, and when the pull is continued, the cutout 50 of the reinforcement 49 is cut and the cutout 27 of the upper surface is simultaneously cut off. Will be opened bottle cap (1).

As a sixth embodiment (see also FIG. 16), the peculiarity of the present invention is that the reinforcing portion 52 protects the cutout portion 27 of the main body.

Since the outer end portion of the reinforcing portion 52 protects a part of the cutting portion 27 from the upper side, there is no fear that the cutting portion 27 will be broken during insertion, and the outer end portion of the reinforcing portion 52 may also be cut out when inserted. 27) opened in such a way as to be opened in the manner stated above.

As a seventh embodiment, the present invention, as shown in FIG. 18, when the bottle cap 1 is assembled to the bottleneck 100, the protrusion 43 is pulsed by the bottleneck outer diameter so that the pull handle 5 is different from the bottleneck. There is a characteristic attached.

As an eighth embodiment, when the support part 42 is pushed to the side part in the same state as in FIG. 19, the support part 42 is inserted into the space part 44 and the pull handle 5 is the bottleneck 100 as shown in FIG. ) To stick to.

As described above, the present invention relates to a one-touch bottle cap that can achieve a perfect function even with pure synthetic resin.
