  Hereinafter, embodiments of a PET bottle cap according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a cap, and FIG. 2 is an overall view when the cap is attached to a plastic bottle.

  As shown in FIGS. 1 and 2, the PET bottle cap 1 according to the present embodiment is attached to the inner side surface 1 b so that it can be screwed with a screw portion formed on the mouth portion 5 a of the commercially available PET bottle 5. A threaded portion 1c is formed. Moreover, the cap 1 is provided with the hook part 3 which is a holding means formed integrally with the main body of the cap 1 on the inner top surface 1a. The hook portion 3 is formed in a ring shape having an insertion portion 3a for inserting the hanging portion 7a of the tea bag 7, and the insertion portion 3a is closed by the retained elasticity. Further, as shown in FIG. 1, the insertion portion 3 a has a bent portion 3 b in order to facilitate insertion of the hanging portion 7 a of the tea bag 7.

  Here, the hook portion 3 is formed so as to protrude from the opening surface 1e of the cap 1 body so that the insertion portion 3a can attach and detach the tea bag 7 at a position outside the opening surface 1e of the cap 1 body.

  Moreover, what is necessary is just to use the material normally used for the cap of a PET bottle as the material of the cap 1, For example, a polypropylene etc. can be mentioned.

  As shown in FIG. 2, the tea bag 7 includes a hanging portion 7 a, and the hanging portion 7 a is configured to be hooked on the ring-shaped hook portion 3. In the present embodiment, the hanging portion 7a is a string that forms a ring. Here, the hanging portion 7a may be formed as a hanging portion 3a by providing a hole in itself instead of the string. In this case, as shown in FIG. 3, it is preferable that the hook portion 3 has a sufficient length and the tea bag 7 is positioned near the center of the plastic bottle 5.

  Next, a method of using the cap 1 having the above configuration will be described with reference to FIGS.

  First, as shown in FIG. 1, the hook part 3 is formed in a ring shape by the insertion part 3a being closed by its retained elasticity. Here, the insertion portion 3a is manually opened against the urging force of the retained elasticity, or the insertion portion 3a is opened by pushing the suspension portion 7a of the tea bag 7, so that the suspension portion of the tea bag 7 is opened. 7a is passed through the hook portion 3 closed in a ring shape. By doing so, as shown in FIG. 4, the hanging portion 7 a is hooked on the ring-shaped hook portion 3, and the tea bag 7 is suspended from the cap 1. In addition, since the insertion part 3a of the hook part 3 is configured to be positioned below the opening surface 1e of the main body of the cap 1, the hanging part 7a is easily hooked to the hook part 3.

  And the tea bag 7 is inserted from the opening part 5a of the plastic bottle 5, and water or hot water is continuously put into the plastic bottle 5 from the opening part 5a. Thereafter, as shown in FIG. 2, the inside of the plastic bottle 5 is sealed by screwing the cap 1 into the mouth portion 5 a of the plastic bottle 5. Note that the tea bag 7 may be inserted into the plastic bottle 5 after water or hot water is placed in the plastic bottle 5. Here, since the hook part 3 is formed in a ring shape by closing the insertion part due to its retained elasticity, the hanging part 7 a can be hooked on the liquid material filling the PET bottle 5. It will not come off.

  The tea bottle 5 containing the water or hot water and the tea bag 7 is left as it is for a predetermined time or shaken to sufficiently extract tea components from the tea bag 7 to make tea in the plastic bottle 5. . Here, when the tea bag 7 from which tea components are sufficiently extracted is no longer necessary, when the cap 1 is removed, the tea bag 7 is taken out from the PET bottle 5 because the hanging portion 7a is hooked on the hook portion 3. It is. And the insertion part 3a is opened by the method mentioned above, and the tea bag 7 is removed from the cap 1 by removing the hanging part 7a from the hook part 3. FIG.
