Abstract

The use of plastic bottles is a way of long-term storage and drinking. Plastic bottles have many conveniences, but when one drink is divided into several times, every time the lid is opened and closed, it is difficult to forget or discard it.

The same applies to other containers with lids and bodies, but in general, plastic bottles that are consumed a lot have inconveniences in lids when drinking, and only the body is discarded when discarded. It can also cause problems. This paper focuses on this, so that when the lid is opened, the lid will open on the main body, but it will not be completely removed, so there is no risk of losing the lid. It is structurally improved so that it does not occur, so there is no interference with touching the mouth when drinking a drink, and there are various conveniences. The present invention can be widely applied to bottles having similar structures as well as beverage bottles.

Description

Plastic Bottle Cap {PET BOTTLE CAP}

Looking at the lid structure of the presently distributed plastic bottle 201 has a structure that is not completely separated because the top cap 101 and the lower ring 103 is connected to each other even after opening the lid. However, the upper cap 101 and the lower ring 103 are separated from each other, so that the lid is almost uncomfortable because the lips reach the lid when drinking a drink. This is most often the case. The lower ring 103 which functions to hold the lid on the plastic bottle 201 and the locking jaw 301 is also not machined in a completely integral columnar structure for this reason and is processed to be easily cut in the middle of the ring.

In other words, the top cap 101 and the bottom ring 103 of almost all plastic bottles 201 are completely separated from the plastic bottles 201 at the same time the lid is opened. Therefore, the lid is often lost when dividing and drinking several times, which has the disadvantage that it is not completely collected when collected for recycling. In addition, in the process of filling a plastic bottle with a drink and sealing the lid, in the prior art, the connection part connecting the upper cap 101 and the lower ring 103 is vulnerable and is often broken.

The present invention is identical in appearance to the lid of the everyday plastic bottle 201. Now, the plastic bottle 201 has the same structure as the upper cap 101 and the lower ring 103, but the middle ring 102 in the middle of the upper cap 101 and the lower ring 103, the lower ring 103 is The point is fixed to the locking jaw 301 of the plastic bottle 201 in one circle and the intermediate ring 102 is connected to the upper cap 101 in series so that it is never separated. .

Even when manufacturing the mold, there is no difficulty in manufacturing since the middle ring 102 is inserted in the same structure as the current lid and occupies a little width in the middle. There is no need to make a tool, so it can be applied directly in the field. Also in the production of beverages, the tip 105 is rotated in the direction of insertion during the sealing of the lid and the tip 105 at the protruding portion of the starting point 104 when the lid is closed. Since the protruding portion of the hook is caught and sealed, almost all the forces are concentrated in this portion, so that less force is applied to the stick 203, so that it is not broken and the defects are reduced, thereby contributing to the reduction of the production cost. You can say it is big.

2 is a cross-sectional view showing a three-dimensional state of the lid of the present invention and the state of the lid when assembled to the plastic bottle 201 as the top cap 101, the lower ring 103, the middle ring 102, the assembled state of each part You can compare

Figure 3 is enlarged to facilitate understanding the circular portion 401 in Figure 2 shows a bar 203 connecting the upper cap 101, the middle ring 102, the lower ring 103.

Figure 4 shows the completed form of the upper cap 101, the middle ring 102, the lower ring 103 in a three-dimensional state of the present invention as viewed from the front and back, respectively.

5 is an example of application when the intermediate connecting portion of the present invention is manufactured in left and right symmetry, but in FIG. 3, only one line is formed in the middle connecting string.

In Figure 1, the structure of the general lid is composed of the structure of the upper cap 101 and the lower ring 103, but the subject here is a circular ring-shaped middle ring in the middle of the upper cap 101 and the lower ring 103 ( Insert 102 and cut one circular middle ring 102 and connect one end to the starting point 104 in connection with the top cap 101, and the other end to the end point 105 and the lower ring 103 and By connecting so as not to be separated to perform the function as a connecting string connecting the upper cap 101 and the lower ring 103.

2 is a cross-sectional view of the right side is to be easily compared with the three-dimensional shape of the lid drawn on the left side as the lid is assembled to the plastic bottle 201.

The upper cap 101 is a cylindrical tube having a structure in which one side is blocked, and has an internal threaded portion 106 that can be inserted into the plastic bottle 201 on the inner side thereof, and a male threaded portion 204 on the upper end of the plastic bottle 201 assembled therewith. Forming and forming a hooking jaw 301 encircled in a circular state to protrude below the male screw portion 204, the locking jaw 301 is a cap top cap 101 and the middle ring 102, the bottom ring In the state of Fig. 4, which is not separated from each other, 103 is forcibly inserted and closed while being closed. Here, a small trapezoidal protrusion 202 formed in a plurality of circumferential directions inside the lower ring 103 has a plastic bottle. The protrusion 202 is caught by the locking jaw 301 while being inserted into the lower portion of the locking jaw 301 of the 201 to complete the assembly. When the top cap 101 is rotated in the opposite direction when the lid is closed and the bottom ring 103 is separated, the bottom ring 103 is caught by the locking jaw 301 and is positioned as it is, and only the top cap 101 is separated. . At this time, the thin cap connecting the upper cap 101, the middle ring 102, and the lower ring 103 is separated while the rod-shaped bar 203 is cut.

3 is an enlarged circular portion of FIG. 2, wherein the middle ring 102 located in the middle of the upper cap 101 and the lower ring 103 is positioned at the center as shown in the figure, and the lid is forcedly inserted into the plastic bottle 201. Before the shape is thin, supporting the upper and lower portions cut respectively, the bar-shaped stick 203 is formed in a circular shape in the circumferential direction, the upper cap 101 and the intermediate ring 102, the intermediate ring 102 And the lower ring 103 is configured to connect.

The lower ring 103, which is prevented from being detached by being caught by the catching jaw 301 located below the upper male thread part 204 of the plastic bottle 201, has a circular ring shape that is not cut and a small trapezoid inside the circle. The flat projections 202 are embedded at regular intervals in the circumferential direction, and the protrusions 202 are flexibly bent at the latching jaw 301 when the lid is inserted into the plastic bottle 201 with a flexible state having elasticity. It is inserted into the cut, and after a while, the cap is fixed to the plastic bottle 201 by being caught in the locking jaw 301 while being unfolded in its original state due to its elasticity.

Figure 4 is a three-dimensional lid as a completed form of the present invention, when the lid is opened for drinking beverage, the top cap 101 is lifted up along the screw while the rod 203 connected to the intermediate ring 102 is The upper cap 101 and the intermediate ring 102, the intermediate ring 102 and the lower ring 103 are cut off. The left side shows the shape of the middle ring 102 portion of the middle ring 102 and the starting point 104 connected to the top cap 101 and the end point 105 connected to the lower ring 103. The curved incision line 107 is clearly shown when the lid is opened in the plastic bottle, and the right incision line 107 is constantly shown without the bent connection portion as seen from the left side.

5 is an example of applying the present invention in another form, if the present invention is designed with the middle ring 102 as one, Figure 5 is applied with two connecting straps acting as the middle ring 102 as shown in Figure 4 It can be seen that the connection portion connecting the upper cap 101 and the intermediate ring 102, the intermediate ring 102 and the lower ring 103 to be applied is different in FIG. In this case, the principle and structure are the same, but when the upper cap 101 is separated from the lower ring 103, the middle ring 102 is not connected to one connecting line as shown in FIG. It is symmetrically formed in semicircle and connected by two connecting lines.

When the present invention is applied, the process of separating the plastic bottle 201 body and the lid is applied to all the plastic bottle 201 drinking while opening and closing the lid frequently, as well as carrying a bottle, such as a bottle filled with bottled water, drinking water Only the body is collected and the small lid is not neglected because it is not neglected, but it can solve the garbage problem, and even if you use the lid several times, because the top cap 101 is attached to the plastic bottle, there is no worry of losing it, and the lid is convenient. You can use the container hygienically without placing it in a separate place or storing it separately, and can be conveniently used in that it can be safely and hygienically drinked without worrying about the lid during the process of drinking a drink.
