Description

[Detailed Description of the Invention] The present invention relates to a cap that is fitted into the mouth of a bottle or the like to properly maintain the dispensing state when dispensing liquid.

This type of stopper lid is generally used separately from the outer cap, which is the original lid, but it is designed to be fitted together with the outer cap from the beginning or to be fitted later after use.

In actual use, this prevents the liquid content from gushing out and overflowing the socket, or preventing a large amount of liquid from flowing out at once.

Conventionally, typical examples of this type of stopper lid are shown in FIGS. 1 and 2. The stopper lid A in FIG. A flange is formed on the periphery of the ceiling of the inner cylinder to provide an annular gap.

Although this stopper lid A has a protruding flange that prevents the spouting liquid to some extent, the path from the outflow hole to the annular gap is straight, and the gap between the outer wall opening and the inner cylinder Since the liquid is wide, there is a risk that the liquid may flow from the outflow hole to the annular gap and be directly disturbed and poured out.Also, the filtrate that is poured out from the outflow hole along the inner surface of the outer wall opening may also flow into the liquid path. Since the flow is linear and there is nothing to limit the momentum, the wave width of the outflow is wide.
However, there is a risk that it may fly out due to turbulent flow.

On the other hand, the stopper lid shown in Fig. 2 (Japanese Utility Model Publication No. 53-55355) has an outer circumferential wall and an inner cylinder close to each other, and has a plurality of outflow holes in the bottom of the inner cylinder. It is.

Although the outflow hole of this stopper lid opens to the side, the liquid does not directly gush out, but once the liquid has flowed out of the outflow hole, its force is not suppressed and is poured out over a wide area. It has some drawbacks.

In particular, when the bottle is tilted, the liquid flowing out from the upper half of the plurality of outflow holes passes through the outer surface of the inner cylinder and moves toward the outer peripheral wall, which narrows the width of the liquid. It has the disadvantage of being poured out without any problems.

The present invention aims to eliminate the above-mentioned conventional drawbacks and provide a stopper lid with stable pouring amount and pouring condition.

To explain the embodiment, reference numeral 1 denotes an outer circumferential wall, which is open upward, and the diameter of the outer circumferential surface 1a and inner circumferential surface 1b increases slightly upward.

Reference numeral 2 denotes a flange edge formed at the upper end of the outer circumferential wall 1, and the flange edge 2 and the outer circumferential surface 1a of the outer circumferential wall 1 are seated in close contact with, for example, the upper surface of the mouth part and the inner circumferential surface of the bottle 3, respectively. There is.

One or several protrusions 4 are provided on the inner circumferential surface 1b of the outer circumferential wall 1.

Reference numeral 5 denotes an inner cylinder, which is continuous with the outer circumferential wall 1 via a narrow annular bottom 6.

Therefore, the inner cylinder 5 and the outer circumferential wall 1 have a gap 7 in which they are close to each other at the lower stile portion.

The inner cylinder 5 has a tapered shape whose diameter decreases toward the top, and has a top wall 5a, and the inside thereof is hollow and continuous with the space inside the bottle.

A suitable number of outflow holes 8 are provided in the lower sill portion of the inner cylinder 5 at equal positions on the circumference.

This outflow hole 8 faces the inner circumferential surface 1b of the outer circumferential wall 1.

On the other hand, one to several protrusions 9 are provided on the outer peripheral surface 5b of the inner cylinder 5.

The relationship between the protrusions 9 and the protrusions 4 will be further described later.

Reference numeral 10 denotes vertical ribs integrally formed between the lower stile of the inner cylinder 5 and the outer circumferential wall 1, and an appropriate number of ribs are provided in a balanced manner on the circumference.

The vertical ribs 10 mutually reinforce the inner cylinder 5 and the outer peripheral wall 1.

The relationship between the protrusions 4 on the outer peripheral wall 1 and the protrusions 9 on the inner cylinder 5 is such that, in the case of the embodiment, the protrusions 4 are formed at a position slightly recessed from the upper end of the inner peripheral surface 1b of the outer peripheral wall 1; The stripes 9 are formed near the upper end of the outer peripheral surface 5b of the inner cylinder 5, and are mutually arranged so that the protrusions 4 are positioned forward of the protrusions 9 in the pouring direction.

While maintaining this arrangement condition, each of the protrusions 4 and 9 can be appropriately moved and formed.

The lid is integrally molded from synthetic resin or the like with appropriate strength and elasticity.

Next, to explain the action, the bottle 3 with the stopper cap attached now.
When the bottle 3 is tilted as shown in FIG. 5, the liquid in the bottle 3 flows out through several outflow holes 8.

At this time, from the outflow hole 8a located below the inclined inner cylinder 5, the content liquid changes its flow direction toward the outer peripheral wall 1 side as shown by the arrow A, and flows out with the outflow amount being appropriately suppressed. It migrates along the inner circumferential surface 1b of the outer circumferential wall 1, and after being once dammed by the protruding stripes 4, one strip is stably poured.

On the other hand, liquid also flows out from the outflow hole 8b located on the side other than the lower outflow hole 8a or in the upper half of the outflow hole 8, but this liquid flows to the outer periphery of the inner cylinder 5 as shown by the arrow B. After flowing along the surface 5b, the flow direction is changed to the direction of gravity by hitting the protrusion 9, and after moving along the inner circumferential surface 1b, it is temporarily stopped by the protrusion 4, and the single stream is similarly stabilized. A pouring is made.

The present invention has the above-mentioned configuration, in which protrusions are provided on the inner circumferential surface of the outer circumferential wall and on the outer circumferential surface of the inner cylinder, and the protrusions on the outer circumferential wall side are closer to the spout than the protrusions on the inner cylinder side. Because of this provision, the flow rate and momentum of the liquid flowing out from the outflow hole is suppressed, and even if some liquid flows along the surface of the inner cylinder, the flow path is changed to the direction of gravity by the protrusion of the inner cylinder, and eventually the liquid flows toward the outer peripheral wall. The inner surface will be transferred to the spout side, and the flow will be temporarily stopped by the protrusion on the outer peripheral wall provided near the spout, so the flow force will be further suppressed, and the synergistic effect of the two will further increase the flow. It has the effect of being finally poured out with a single stable trajectory.

In addition, according to the present invention, since liquid dispensing can be controlled reliably, it is particularly effective for caps whose total length cannot be increased, and even if they can be made large, the caps can be made smaller, making it economical in terms of the amount of resin, etc. be.
