[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin liquid pouring cap with a so-called pull ring.

[0002]

2. Description of the Related Art A cap with a pull ring is known. The cap has inner and outer peripheral walls which are fitted to the inner and outer surfaces of the mouth-neck portion from the inner and outer peripheral edges of the flange-shaped top wall to be placed on the upper end surface of the container body and neck portion, and the inner wall of the top wall has an inner peripheral edge. The output cylinder is erected, and the inner surface of the inner peripheral wall is closed with a bottom plate, and a part of the bottom plate is formed as an elongated break portion by forming a thin break line. A pull ring is provided with the ring positioned horizontally in the discharge tube. A cap provided separately can be fitted to the cap.

[0003]

In the conventional cap with a pull ring, the pull ring is strongly pulled upward to remove the broken portion of the cap bottom plate, and the trace for removing the broken portion forms a liquid discharge hole. However, since the bottom plate is horizontal with respect to the inner peripheral wall, and therefore the liquid discharge hole opened in the bottom plate is also horizontal, when the container body fitted with the cap is suddenly tilted, the The liquid in the container may jump out of the pouring hole, and contaminate the surroundings.

In the present invention, the liquid discharge hole is formed to be vertically long to prevent the liquid from escaping, and the cap is provided with a lid for opening and closing the discharge cylinder of the cap via an elastic reversing mechanism. By being attached, the opening and closing of the injection cylinder is facilitated, and the lid is kept open by elastic reversal of the lid so that the lid does not become an obstacle when the liquid is poured.

[0005]

The inner and outer peripheral walls 4 and 5 to be fitted to the inner and outer surfaces of the mouth-neck portion are provided vertically from the inner and outer peripheral edges of the flange-shaped top wall 3 placed on the upper end surface of the mouth and neck portion of the container body. And the cap body 1 that rises the pouring cylinder 6 from the inner peripheral edge of the top wall.
And a lid 18 for opening and closing the upper surface of the cap body, which is attached to the rear portion of the outer peripheral wall 5 via an elastic reversing mechanism 19, and the inner surface of the inner peripheral wall 4 is placed inside the upper portion of the inner peripheral wall. A bottom plate 8 having a recess in at least the first half thereof and connecting the upper end of a vertical wall 10 rising from the outer edge of the bottom wall 9 to the inner edge of the protrusion via an overhang plate 7 projecting inward from the periphery. Blockage,
And a vertically elongated first removing portion enclosing the front portion of the vertical wall and the front portion of the concave bottom wall connected to the lower end of the front portion together with a thin break line 12.
13, from the bottom wall portion of the concave portion of the first removing portion, and the second removing portion 14 in which a rear part of the bottom plate portion 8 is thinned.
The first and second rod portions 15 and 16 are erected, respectively, and a finger-hanging piece 17 for pulling out both rod portions is positioned between the upper ends of the both rod portions in the above-mentioned pouring cylinder 6 and erected. It was integrally molded with a resin material.

[0006]

[Function] From the state of FIG.
By removing the first and second removing portions 13 and 14 at the lower ends of the first and second rod portions 15 and 16, the discharge hole 30 and the outside air suction hole 31 are opened as shown in FIGS. Make a hole. The pouring hole 30 has a longitudinal section L
It has a vertical wall opening portion 30a and a bottom wall opening portion 30b, so that when the container body fitted with the cap is tilted so that the front portion of the mouth and neck is downward, the container body becomes The liquid that enters the mouth and neck from the inside of the container is first exposed to the vertical wall opening 30a.
, Then through the bottom wall opening 30b of the spout, and the two flows passing through the two openings collide and merge into the spout cylinder 6 and be spouted. . When the liquid is poured out, the lid 18 is located substantially upright with respect to the cap body 1, but is attached to the rear part of the cap body outer peripheral wall 5 via the elastic inversion mechanism 19, The liquid does not fall forward of the dispensing cylinder 6 and does not hinder the liquid dispensing.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a cap body which has inner and outer peripheral walls 4 and 5 fitted from the inner and outer peripheral edges of a flange-shaped top wall 3 to be placed on the upper end surface of a container mouth and neck portion 2 to the inner and outer surfaces of the mouth and neck portion. The pouring cylinder 6 is vertically erected, and its upper end is expanded outward from the inner peripheral edge of the top wall. The inner surface of the inner peripheral wall 4 is closed by a bottom plate portion 8 via an overhanging plate 7 projecting downward and inward from the upper end of the inner peripheral wall. The bottom plate has a recess in at least the front half thereof, and a vertical wall 10 stands upright from the outer edge of the bottom wall 9 of the recess to connect the upper end to the inner edge of the overhang plate 7. In the illustrated example, the front half of the bottom plate portion is provided with an inclined plate 11 to form a concave portion. The front portion of the vertical wall and the front portion of the concave bottom wall connected to the lower end of the front portion are both surrounded by a thin break line 12 to form a vertically elongated first removing portion 13, and a rear part of the bottom plate portion 8 is thinned. As the second removing unit 14,
First and second rod portions 15 and 16 are erected from the bottom wall portion of the first removing portion and the second removing portion 14, respectively, and a finger hook 17 for pulling out both rod portions is erected between the upper ends of these two rod portions. I do. As shown in the figure, the finger hook is a ring, and the front and rear portions of the ring are connected to the upper ends of both rod portions, and the ring is provided horizontally with respect to the pouring cylinder and positioned in the pouring cylinder. Good.

It is desirable that the front portion of the bottom wall of the first removing portion 13 is formed as small as possible. Reference numeral 18 denotes a lid that opens and closes the upper surface of the cap body 1 and is attached to the rear portion of the outer peripheral wall 5 via an elastic inversion mechanism 19. The elastic reversing mechanism may be a so-called three-point hinge other than the elastic reversing plates provided as a pair of left and right as shown in the illustrated example, or may be various known examples.

A ridge 3a for engaging the lid is provided in the front half of the top wall 3 between the outer edge of the top wall and the pouring cylinder 6, and the outer edge of the ridge when the lid is closed is formed. A fitting groove 20 is provided on the inner surface of the front half of the peripheral wall of the lid.

The entire cap is integrally formed of a synthetic resin material. The integral molding can be performed in the open state of FIG.

[0011]

[Effects of the Invention] Since the present invention has the above-described configuration, the finger hook 17
By pulling up, the discharge hole 30 and the outside air suction hole 31 are opened, and the discharge hole 30 has an L-shaped longitudinal section, and the cap is fitted so that the lid 18 attached to the rear portion of the cap body does not interfere. When the container body is tilted so that the front of the combined container body neck and neck faces downward, the flow of liquid flowing through the vertical wall opening 30a and the flow of liquid flowing through the bottom wall opening 30b are reduced. The flow collides with the flow and the merged liquid is discharged, so that the discharged liquid does not jump out of the discharge cylinder 6 as in the related art. In addition, since the lid 18 is attached to the rear portion of the outer peripheral wall 5 of the cap body via the elastic reversing mechanism 19, the lid does not move from the open position to the closed position unintentionally, and the liquid is discharged. Therefore, when the container body is tilted, the lid body is inadvertently moved and touches the liquid to be poured, so that the liquid to be poured is not scattered and the surrounding area is not polluted.
