The inner surface of the attachment part 110 has a screw shape similar to the inner surface of a general PET bottle cap, and can be attached to the PET bottle by turning it.

  The liquid passage portion 112 is provided on the side far from the lid portion 120 and the hinge portion 130. On the other hand, the air passage portion 114 is provided on the side close to the lid portion 120 and the hinge portion 130. In a state where the plastic bottle cap 100 is attached to the plastic bottle (FIG. 4), when the liquid is poured from the plastic bottle, the liquid is poured from the opposite side of the hinge portion 130. Therefore, the liquid passage part 112 is provided on the side far from the lid part 120 and the hinge part 130, and the air passage part 114 is provided on the side near the lid part 120 and the hinge part 130.

  As shown in FIGS. 1 to 3, the air passage portion 114 is made of a tubular member and allows air to pass inside and outside the PET bottle. The member of the air passage part 114 can be made of, for example, polypropylene resin (PP resin) similarly to the straw. The tip of the air passage portion 114 on the side inserted into the plastic bottle forms an inclined surface as shown in FIG. This can prevent the liquid from flowing into the air passage portion 114 when pouring the liquid from the plastic bottle.

  The button 116 functions together with the lock portion 122 on the lid portion 120 side to constitute an opening / closing mechanism for the lid portion 120. When the plastic bottle is not used, the lid portion 120 is closed, and the lock portion 122 and the button 116 are engaged to lock the lid portion 120 in the closed state. When the plastic bottle is used, the engagement between the lock portion 122 and the button 116 is released by pressing the button 116. The lid part 120 is opened by the elastic force of the hinge part 130.

(Cover 120)
As shown in FIGS. 1 to 3, the lid part 120 is provided integrally with the attachment part 110 via the hinge part 130. The lid part 120 is closed when the plastic bottle is not used, and covers the liquid passage part 112 and the air passage part 114. By providing such a lid 120, it is possible to prevent liquid from spilling from the plastic bottle. Moreover, the liquid passage part and the air passage part can be kept hygienic when the plastic bottle is stored.

  The lid part 120 is provided with a lock part 122. As described above, the lock part 122 functions together with the button 116 on the attachment part 110 side to constitute an opening / closing mechanism for the lid part 120.

(Hinge part 130)
As shown in FIGS. 1 to 3, the hinge part 130 integrally connects the attachment part 110 and the lid part 120. The spring constituting the hinge part 130 has a natural length when the lid part 120 is opened. By doing in this way, when the cover part 120 is in the closed state, the cover part 120 is opened by the elastic force of the hinge part 130 by pushing the button 116.

  The pet bottle cap 100 according to the present embodiment has been described above with reference to FIGS. FIG. 4 is a diagram showing a state in which the PET bottle cap 100 is attached to the PET bottle 200, and shows a state in which the lid 120 is closed when the PET bottle 200 is not used.

  When the plastic bottle 200 of FIG. 4 is used, the lid 120 can be opened by pressing the button 116 of the attachment unit 110 as described above. Then, the liquid can be poured from the plastic bottle 200 by tilting the plastic bottle 200 away from the hinge portion 130 (right side of the paper). By providing the PET bottle cap 100 with the air passage portion 114 (FIGS. 1 to 3), an appropriate amount of air can be circulated into the PET bottle 200, and liquid can be poured easily from the PET bottle 200.

  As described above, according to the present embodiment, the tubular air passage portion 114 is provided in parallel with the liquid passage portion 112, so that when the liquid is poured from a plastic bottle into a glass or the like, the inclination of the plastic bottle 200 is increased. Air can be sent into the plastic bottle 200 from the air passage portion 114 without being aware of the angle. In this way, it is possible to easily pour the liquid from the plastic bottle.

  Moreover, it is possible to prevent liquid from spilling from the plastic bottle 200 by providing the lid 120 and covering the liquid passage part 112 and the air passage part 114 when the plastic bottle 200 is not used. Moreover, the liquid passage part 112 and the air passage part 114 can be kept hygienic.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope described in the claims for utility model registration, and these are naturally within the technical scope of the present invention. It is understood.

  For example, in the above-described embodiment, the configuration in which the attachment portion 110 includes the lid portion 120 via the hinge portion 130 has been described, but the present invention is not limited to this. The main feature of the present invention is that a tubular air passage portion 114 for allowing air to pass inside and outside the PET bottle is provided. Therefore, the lid part 120 and the hinge part 130 are not necessarily indispensable components, and may be a cap for a plastic bottle including only the attachment part 110. Moreover, when providing a cover part, the hinge part which connects a cover part, etc., these may be arbitrary structures.

  Further, in the above-described embodiment, the configuration has been described in which the button 116 is provided on the attachment portion 110, the lock portion 122 is provided on the lid portion 120, and the lid portion 120 can be opened by pressing the button 116. It is not limited to this. An arbitrary configuration can be adopted for the opening / closing mechanism of the lid 120.

  The present invention can be used for a PET bottle cap attached to a PET bottle.
