Abstract

<P>PROBLEM TO BE SOLVED: To provide a cap which allows a ring the cap remaining on a PET bottle body to be removed easily at the first opening of the cap. <P>SOLUTION: A ring 3 is linked to a cap 1 via a link portion 4. Although a conventional connection 2 is broken at the first opening of the cap 1, the ring 3 and the cap 1 are not separated apart but are removed together from a PET bottle 8. When a ring connection 5 is formed on part of the ring, the ring 3 is divided easily. When an assist hook 6 is formed on the ring, the assist hook is fixed by finger tips to help breaking the ring connection 5. In this manner, the ring 3 is removed easily from the PET bottle 8. After removal of the ring 3 from the PET bottle, the cap 1 can be separated from the ring via a cut-divide portion 7 formed on the link portion 4 to allow reuse of the cap 1 only. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a cap for PET bottles that increases the separation and recovery rate, characterized by removing the ring under the cap remaining in the PET bottle main body after opening the cap of the PET bottle.

In the separate collection of used PET bottles, it is difficult to remove the ring under the cap. Therefore, the PET bottle is often collected with the ring under the cap attached.

JP 2006-176204 A

  In the separate collection of used PET bottles, after opening the PET bottle cap, the problem of the ring under the cap remaining in the PET bottle body can be easily removed at the first opening. Let it be an issue.

  Conventionally, the ring part (3) remaining under the cap part (1) of the PET bottle and the cap part (1) remaining after opening is connected by providing the linkage part (4) and is cut at the first opening. The cap part (1) and the ring part (3) can be simultaneously removed from the plastic bottle part (8) without being separated by the mold connecting part (2). When the ring part (3) is provided with a notched ring connection part (5) in a part of the ring part, the ring part (3) is easily divided, and when the auxiliary hook (6) is provided. By fixing the auxiliary hook (6) with a fingertip and opening it, the cutting of the ring connecting portion (5) is assisted, and the ring portion (3) is easily removed from the PET bottle body. After removing from the plastic bottle body, the cap part (1) and the ring part (3) can be separated by the cut part (7) provided in the linkage part (4), so only the cap part (1) is re-installed. A cap for PET bottles that increases the separation recovery rate, characterized by being usable.

  The present invention eliminates the inconvenience of cutting the ring part (3) under the cap after opening the cap part (1) of the plastic bottle with a tool or removing it with a fingertip, and recycling the resource garbage. It is the effect of the present invention that facilitates the separation and collection in the environment, and the purpose is to achieve a recycling effect including environmental and resource problems.

Embodiments of the present invention will be described below.
Since the cap part (1) and the ring part (3) are removed in a state of being linked at the time of initial opening, the linkage part (4) needs to be strong enough not to be separated at the time of initial opening, and the ring connecting part (5) Since it is divided at the time of opening, it is desirable to have a strength that can be divided, and the conventional connection part (2) of the PET bottle cap currently distributed is weaker than the ring connection part (5). When it is necessary to attach the cap portion (1), it is desirable that the cap portion (1) has such a strength that it can be torn off by manually applying force from the cut portion (7) of the linkage portion (4). Further, when the sizes and strengths of the parts in all drawings are compared, they are not necessarily proportional, and may be equivalent or reversed.

  Further, when the ring connection portion (5) is difficult to be divided at the time of opening, it is desirable to continue the opening while pressing the auxiliary hook (6) with a finger.

  Furthermore, when the ring part is relatively easy to come off due to the shape of the ring stopper below the threaded part of the PET bottle mouth and the slide stopper on the inside of the ring part, as shown in the form diagram of FIG. A conventional unbroken ring that excludes 5) and the auxiliary hook (6) may be used. Moreover, the form which excluded only the auxiliary hook (6) from FIG. 1 may be sufficient.

  FIG. 1 is a perspective view showing a first embodiment of the present invention. As shown in the figure, the plastic bottle cap of the present invention has a cap part (1), a conventional connection part (2), a ring part (3), a ring connection part (5) that links the ring part, an auxiliary hook (6), And the link part (4) which links a cap part (1) and a ring part (3), and the slit part (7) are comprised.

FIG. 5 shows a state where the cap of FIG. 1 is attached to a plastic bottle. 6, 7 and 8 show the use state of the cap. FIG. 6 shows a state in which a finger is attached to the auxiliary hook (6) of the ring portion (3) and the ring connection portion (5) having a vertical cut is assisted by pressing with the finger. Thus, it is easy to remove the ring portion (3). 7 and 8 show a state after opening and a use state. By rotating the cap part (1) for opening, the ring part (3) attached so as not to be lifted from the mouth part of the plastic bottle is rotated with the cap while the conventional connection part (2) Although it cut | disconnects and it divides | segments into a cap part (1) and a ring part (3), it is opened with connecting by providing a connection part (4). By providing the ring connecting portion (5) with a vertical cut in the ring portion (3), the ring portion (3) is cut when the cap is opened, and the ring portion is easily removed. Moreover, the cutting | disconnection of a ring connection part (5) is assisted by pressing down an auxiliary | assistant hook (6) with the fingertip of one hand other than the hand which opens a cap.

  FIG. 2 is a perspective view showing a second embodiment of the present invention. As shown in the drawing, this is an embodiment characterized in that the cut of the ring connecting portion (5) is inclined rightward from the upper right to the lower left.

  FIG. 3 is a perspective view showing a third embodiment of the present invention. As shown in the drawing, this is an embodiment characterized in that the cut of the ring connecting portion (5) is inclined leftward from the upper left to the lower right.

  FIG. 4 is a perspective view showing a fourth embodiment of the present invention. As shown in the figure, this is an embodiment characterized in that it is a conventional continuous ring without a ring connection portion (5) and an auxiliary hook (6). This is the shape of a ring stopper under the threaded part of the PET bottle mouth and a slide stopper on the inside of the ring part. If the ring part is relatively easy to come off, the ring connecting part (5) and the auxiliary hook (6 ) May not be provided. In that case, since only the linkage part (4) and the cutting part (7) are required, the structure can be simplified and the cost can be reduced.
