It must be interpreted with meaning and concept consistent with the technical idea of the present invention according to the principle that it can be done.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent the entire technical idea of the present invention, so various equivalents can be substituted for them at the time of filing the present application. It should be understood that there may be variations.

[rope( ROPP ) cap's composition]

The rope (ROPP) cap according to the present invention includes a main body 100 and a skirt 200, as shown in [FIGS. 5] to [FIG. 7]. And the main body 100 and the skirt 200 are connected by a bridge 210. At this time, a long slot 220 is formed between the bridges 210 in the rotation direction of the main body 100, and the skirt 200 A split 230 is formed in the width direction.

In particular, the slot 220 is formed so that both edges facing each other are curved inward, so that when the main body 100 and the skirt 200 are separated, the ROPP cap can be opened safely by preventing hands from being cut by the edges. It was made to exist.

In addition, the split 230 is formed to contact one end of one slot 220, so that defects do not occur when manufacturing the ROPP cap, and it can be easily separated between the slot 220 and the split 230 with a small amount of force. The ROPP cap can be opened easily and conveniently by tearing it easily and in a designated direction.

At this time, the extension section 231 connecting the slot 220 and the split 230 extends in the direction in which the main body 100 rotates and then extends in the width direction of the skirt 200 to form an overall “L” shape. By configuring it to use the existing ROPP cap device as is, the shape of the blade forming the split 230 is changed, making it easy to manufacture and use safely.

In addition, the extension section 231 is formed in a round shape, so that when force is applied to the main body 100 to rotate, it is naturally cut and broken along the extension section 231 in the slot 220, making it easy to remove the ROPP cap with little force. It is open and safe to use.

Hereinafter, this configuration will be described in more detail with reference to the attached drawings.

go. main body

As shown in [FIGS. 5] to [FIG. 7], the main body 100 is configured to be screwed to a container such as a bottle to block the entrance. This body 100 is manufactured in a shape similar to the entrance part of the container, and has a female thread on the inside for fastening by a screw fastening method, an airtight material on the inner side to maintain airtightness with the container, and a ROPP cap on the outer edge. Kernels are formed to prevent slipping.

In this main body 100, as shown in [FIG. 5] to [FIG. 7], a ring-shaped skirt 200 is connected to the bridge 210 so that the main body 100 cannot be opened without being forcibly rotated. It is composed.

me. skirt

The skirt 200 is formed by forming several slots 220 long in the direction of rotation of the main body 100 at the entrance portion of the main body 100 described above, as shown in [FIGS. 5] to [FIG. 7]. . At this time, the skirt 200 is formed in a ring shape connected to a bridge 210, which will be described later, and the ring shape is cut based on a split 230, which will be described later, and is attached to the main body 100 in the form of a strip to separate the ROPP cap. make it possible This skirt 200 includes a bridge 210, a slot 220, and a split 230.

1. Bridges and slots

Several slots 220 are formed along an imaginary circumference in the lower part of the main body 100, as shown in [FIGS. 5] to [FIG. 7]. At this time, a portion connecting the main body 100 and the skirt 200 located below it between the two adjacent slots 220 forms a bridge 210. Accordingly, when the bridge 210 is rotated in place by applying force to the main body 100, the bridge 210 between the slots 220 is easily cut by receiving the force, to the extent that the ROPP cap can be easily opened in a container such as a bottle. It is desirable to form it with the width and number of .

In particular, the slot 220 is preferably formed so that the edges facing each other on both sides are curved inward, as shown in [FIG. 5]. This means that when the ROPP cap is opened, the slot 220 is separated in the longitudinal direction and both edges are divided. At this time, there is a risk that the separated edges may cause injury to the user's fingers or palm. Accordingly, the purpose is to round the edges, which can cause injury, so that the ROPP cap can be used safely without injury even if it is opened. Of course, as it is formed to be curved like this, the curved part may get caught in the forming roller, but it can be easily removed from the forming roller by forcibly pulling it out using pneumatic pressure or the like.

2. split

The split 230 is formed long along the width direction of the skirt 200 described above, as shown in [FIGS. 5] to [FIG. 7]. At this time, the split 230 can be used by opening the ROPP cap by causing the ring-shaped skirt 200 to be cut and separated into a strip shape by rotating the fixed main body 100. let it be To this end, the split 230 is cut into a portion of the thickness of the skirt 200, and when the main body 100 is rotated, the split 230 connected to the main body 100 by the bridge 210 becomes a slot (as described later). 220), it is desirable to configure it so that it can be easily cut and separated.

This split 230 is formed so that one side is connected to one end of one slot 220, as shown in [FIGS. 5] to [FIG. 7]. This is because the split 230 is formed in part of the thickness of the skirt 200, and the skirt 200 is attached to the main body 100 as a whole when manufacturing the ROPP cap, resulting in manufacturing defects such as deformation or tearing. While preventing this, when force is applied to the main body 100 to open the ROPP cap, the force is easily transmitted from one end of the slot 220 to the split 230 and is cut, forming a ring-shaped skirt 200. This is to allow the ROPP cap to be easily opened by changing into a strip shape.

In particular, in a preferred embodiment of the present invention, the split 230 extends from one end of the slot 220 in the direction in which the main body 100 rotates, as shown in [FIG. 5], and then extends to the width of the skirt 200. The extension section 231 bent in the direction, that is, the extension section 231, can be formed to have an 'ㄱ' shape. This is because the split 230 is usually formed to be located between two neighboring slots 220, so it can be easily manufactured and safely used by changing only the blade shape that forms the split 230 while using existing equipment. This is to make it possible.

In addition, in a preferred embodiment of the present invention, the split 230 can be formed to round the above-described extension section 231, as shown in [FIG. 6]. This is because the force applied when opening the ROPP cap by applying force to the main body 100 is cut into the shape of this extension section 231 and the cut extends to the split 230, so that the cut portion is as shown in [Figure 5]. This is to make it safer to use by making it round rather than sharp.

And in a preferred embodiment of the present invention, the split 230 may be formed to be long in the width direction of the skirt 200 right at one end of the slot 220, as shown in [FIG. 7]. At this time, the split 230 can be easily manufactured by slightly adjusting the mounting position of the blade forming the split 230 in an existing manufacturing device and extending its formation length so that it can reach the slot 220.

As described above, in the present invention, both edges of the slot are curved inward, thereby preventing safety accidents such as cuts to the hand at the edge of the main body entrance when the ROFF cap is opened. In addition, as the split forms an extension section that extends to one end of the slot, the skirt can be easily separated along this extension section even if a small force is applied when opening the ROPP cap and can be used safely.
