Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a watering can cap used to reuse a used plastic bottle as a watering can.

[0002]

[Prior art]

 As caps for using used PET bottles as watering cans, those described in Utility Model Registration No. 3022886 and Utility Model Registration No. 3033827 have been proposed.

[0003] Each cap is connected to a screw portion provided at the mouth of the PET bottle, and is provided with a screw cylinder screwed to the screw portion. Then, many small-diameter holes are opened in the cap, and water is discharged from these holes. The latter cap is provided with an air intake pipe that penetrates the cap, so that when used as a watering can, air can be taken into the PET bottle to enable continuous use.

[0004]

[Problems to be solved by the invention]

 This type of conventional cap is screwed into a threaded part of a plastic bottle. However, currently two types of diameters are used in the mouth of PET bottles in Japan, so in order to adapt to these two types of diameters, the diameter of the screw cylinder of the cap is also two types. Things needed to be easy.

In a conventional watering cap, two types of screw cylinders having different diameters are provided on the upper and lower sides to support plastic bottles of different diameters. Was. In addition, if the accuracy of the screw cylinder is inferior, water may leak from the screw portion. Therefore, when screw cylinders of two different diameters are provided on the upper and lower sides, there has been a problem such as an increase in manufacturing cost, such as a need for these screw cylinders to have a somewhat high degree of accuracy.

[0006] In addition, in the case where the air intake pipe penetrating through the cap is provided, it can be used continuously as a watering can, but it is necessary to insert a long air intake pipe into the inside of the plastic bottle. In addition, the time and effort required for mounting was further troublesome. In addition, when the cap is attached or detached, there is a problem in strength such that the air intake pipe may come off the cap body.

Furthermore, in order to repeatedly use a used plastic bottle as a watering can, it is necessary to constantly supply water to the plastic bottle. However, since the diameter of the PET bottle is almost the same as the diameter of the household tap for water supply, it is not a convenient size for refilling the PET bottle with water. Therefore, when used as a watering can, the work of replenishing the water was troublesome.

Therefore, the present invention has been devised in order to solve the above-mentioned problem, and it is extremely easy to mount the plastic bottle to the mouth and to easily supply water to the plastic bottle. It is an object of the present invention to provide a watering can cap that can be used.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, a first means of the present invention is to form a cylindrical body 10 having an insertion port 11 inserted into the mouth 2 of the plastic bottle 1 and a discharge port 12 expanding at the tip of the mouth 2. The cap body 20 is provided with a cap body 20 which is detachably attached to the discharge port 12 of the cylindrical body 10. I have provided an entrance.

The second means is to provide a tapered outer peripheral surface of the insertion opening 11 to form a cylindrical shape in which an end of the insertion opening 11 is narrowed, and to form a band-shaped flat surface along the longitudinal direction of the outer surface of the insertion opening 11. A portion 13 is provided, and a gap formed between the inner peripheral surface of the mouth portion 2 of the plastic bottle 1 and the flat portion 13 of the insertion port 11 is defined as an air inlet 3.

The cap member 20 of the third means is connected to the cylindrical body 10 by a connecting member 30 provided on the side of the cylindrical body 10 opposite to the flat portion 13, and the connecting member 30 is tilted when the watering can is used. Mark.

A fourth means is a means for solving the problem in that the diameter of the outlet 12 is expanded so as to be larger than the diameter of the water tap.

[0013]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The structure of the cap of the present invention comprises a cylindrical body 10, a cap body 20, and a connecting member 30 (see FIG. 1).

The cylindrical body 10 has a cylindrical shape in which an insertion port 11 is provided at one end and a discharge port 12 is provided at the other end. The insertion port 11 is a portion to be inserted into the mouth portion 2 of the plastic bottle 1 and is tapered, and is formed in a cylindrical shape with a narrowed end (see FIG. 2). The tapered outer peripheral surface of the insertion port 11 and the inner peripheral surface of the mouth portion 2 of the plastic bottle 1 are fitted to each other to form a sealed state (see FIG. 1). Further, the tapered outer peripheral surface can correspond to the mouth portion 2 having different diameters of the plastic bottle 1.

Further, a band-shaped flat portion 13 is provided along the longitudinal direction of the outer surface of the insertion port 11 (see FIG. 3). The gap formed between the inner peripheral surface of the mouth portion 2 of the plastic bottle 1 and the flat portion 13 of the insertion port 11 is used as the air inlet 3. The air intake 3 formed by the flat portion 13 is used such that the air intake 3 is positioned on the upper surface of the cylindrical body 10 when the watering cap is tilted during use. No water is discharged from the intake 3 (see FIG. 1). In addition, a connector 30 described later is used as a mark so that the air inlet 3 is always located on the upper surface of the cylindrical body 10.

The outlet 12 is a portion for discharging water from the inside of the plastic bottle 1. The outlet 12 spreads at the tip of the mouth portion 2 of the plastic bottle 1, and a cap body 20 is detachably attached to the outlet 12 (FIG. 3). reference). By expanding and forming the diameter of the discharge port 12 so as to be larger than the diameter of the tap, it becomes possible to directly supply the PET bottle 1 from the tap with the PET bottle 1 placed. In this case, if the diameter of the discharge port 12 is formed to a diameter of at least 25 mm to 35 mm, replenishment can be reliably performed.

The cap body 20 is detachably attached to the discharge port 12, and has a large number of small-diameter discharge holes 21 formed in a plate surface 22 of the cap body 20 (see FIG. 4). When the cap body 20 is attached to the discharge port 12 and the PET bottle 1 is tilted, the plastic bottle 1 is drained from the discharge hole 21 into multiple strips like a watering can. Although the illustrated cap body 20 has a shape that is externally fitted to the outer surface of the outlet 12, it may have a shape that is forcibly fitted to the inner surface of the outlet 12, and the shape of the plate surface 22 may also be different. The shape of the cap body 20 is not limited to the illustrated example because it can be arbitrarily changed.

The cap body 20 is connected to the cylindrical body 10 by a connector 30 (see FIG. 1). The connecting tool 30 is provided on the side surface of the cylindrical body 10 opposite to the flat portion 13, and serves as a mark indicating the tilt direction of the plastic bottle 1 when using a watering can. That is, when the plastic bottle 1 is inclined to the connecting tool 30, the connecting tool 30 is located on the lower surface of the tubular body 10. Then, at the same time, the flat portion 13 is located on the upper surface of the cylindrical body 10, and as a result, the air intake 3 is opened on the upper side surface of the cylindrical body 10, so that normal use can be performed. Although the illustrated connection tool 30 has a substantially string shape, the connection tool 30 can be changed to another shape as long as the cap body 20 and the cylindrical body 10 can be detachably connected. In addition, since the connecting tool 30 is used as a mark, it is desirable that the connecting tool 30 has a shape that is as visible as possible, as in the illustrated example.

In the drawing, reference numeral 14 denotes a reinforcing flange formed on the side surface of the discharge port 12, and reference numeral 23 denotes a contact flange formed on an opening edge of the cap body 20 (see FIG. 3). . When the cap body 20 is fitted into the outlet 12, the contact flange 23 is brought into contact with the reinforcing flange 14 to enhance the sealing performance. In addition, by providing the above-described string-shaped connecting member 30 between the side edges of the reinforcing flange 14 and the contact flange 23, the position of the connecting member 30 is made more conspicuous (see FIG. 1).

[Effect of the invention]

 The present invention has achieved the original object by being configured as described above.

That is, a cylindrical body 10 having an insertion port 11 inserted into the mouth portion 2 of the plastic bottle 1 and a discharge port 12 expanding at the tip of the mouth portion 2 is formed. The cap body 20 is provided with a detachable cap 20, a large number of small-diameter discharge holes 21 are formed in the cap body 20, and the air inlet 3 is provided on the outer surface of the insertion opening 11 of the cylindrical body 10. By simply inserting the insertion opening 11 of the cylindrical body 10 into the opening 2, the mounting can be easily performed, and the water can be continuously discharged.

Further, since the outer peripheral surface of the insertion port 11 is tapered to form a cylindrical shape in which the end of the insertion port 11 is narrowed, the different diameter 2 of the PET bottle 1 can be used without the user's awareness. Can be made to correspond. Further, a band-shaped flat portion 13 is provided along the longitudinal direction of the outer surface of the insertion opening 11, and a gap formed between the inner peripheral surface of the opening 2 of the plastic bottle 1 and the flat portion 13 of the insertion opening 11. Since the air inlet 3 is used, the manufacturing is easier and the strength is superior to that using a conventional air inlet pipe.

Further, the cap body 20 is connected to the cylindrical body 10 by a connecting member 30 provided on the side of the cylindrical body 10 opposite to the flat portion 13, and the connecting member 30 is a mark indicating an inclination direction when a watering can is used. By doing so, normal use without water leakage is possible no matter who uses it.

Since the diameter of the outlet 12 is expanded so as to be larger than the diameter of the tap, it is possible to easily supply water into the plastic bottle.

As described above, according to the present invention, various useful effects such as extremely easy attachment of the plastic bottle to the mouth and easy supply of water into the plastic bottle can be achieved. To play.
