Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is intended to smoothly pour the content liquid such as beer or juice, which is attached to the neck of the container body and stored in the container body. The present invention relates to a pouring plug of a non-directional type (a type in which either side of the pouring plug may be faced down when pouring) and a simple opening lid with a pouring plug having a simple opening function.

(Prior Art) Conventionally, as means for smoothly pouring liquid such as beer or juice contained in a container body, for example, Japanese Utility Model Publication No. 57-46450 and Japanese Utility Model Publication No. 57-63097 are known. There is known a spout having an spout and an air suction port as described in US Pat.

Before pouring out the liquid inside the container body, these spouts are used by replacing the sealing lid on the mouth and neck of the container body with the sealing lid on the neck and neck of the container body removed. A cylindrical sealing wall portion for tightly fitting in the rear opening portion and a flange portion for preventing excessive insertion are provided.

On the other hand, it serves as a guide when pouring out the content liquid, and as a means for facilitating pouring of the pouring liquid in the intended direction without scattering, it protrudes upward from the inside of the sealing wall part above the collar part. A spout pipe is provided. An air suction pipe having a diameter smaller than that of the spout pipe is provided on one side inside the spout pipe from the tip of the spout pipe to a position further below the lower end of the spout pipe. This air suction pipe absorbs outside air through the air suction pipe into the container when the pressure inside the container becomes negative due to the decrease of the liquid content during pouring, so the pulsation of the liquid is buffered and the container smoothly flows. It can be poured out.

In addition, before pouring out, a pouring plug which is previously attached to the neck of the container body is proposed in Japanese Utility Model Publication No. 58-12756, even if it is not replaced with a sealing lid attached to the neck of the container body. There is.

This pouring plug is provided with a cylindrical plug body portion fitted in the opening portion of the mouth neck portion (bottle mouth), and a flange portion that engages with a locking portion on the outside of the bottle mouth for preventing disengagement, A spout pipe extending upward from the lower end of the plug body is provided.

This pouring pipe is formed in a substantially semi-circular cross-section, and when the content liquid is poured out by providing an outwardly inclined dovetail (guide) on the arc-shaped side surface of the upper end opening of the pouring pipe. With the mouthpiece side facing downward, it serves as a guide so that the pouring liquid can be poured in the desired direction without scattering. Further, a lid piece is provided on the straight side surface of the pouring pipe upper end opening opposite to the mouthpiece so that the upper end opening can be easily sealed.

In the embodiment, an outer lid such as a crown is capped on the outside of the pouring plug to ensure hermeticity during transportation.

It should be noted that this pouring plug is not provided with an air intake port that functions to buffer the pulsation of the pouring liquid.

(Problems to be solved by the invention) However, the pouring plugs disclosed in Japanese Utility Model Publication No. 57-46450 and Japanese Utility Model Publication No. 57-63097 have the following problems.
This is troublesome because the consumer has to replace the sealed lid that is pre-mounted on the neck of the container body.

Further, these pouring stoppers are troublesome to operate because it is necessary to tilt the container so that the air suction pipe side provided on one side inside the pouring pipe is the upper side when pouring out the content liquid. is there.
Incidentally, if the container is tilted so that the air suction pipe side is on the lower side for pouring, the content liquid pulsates greatly.

Further, since the pouring plug disclosed in Japanese Utility Model Publication No. 58-12756 does not have an air intake port, a large pulsation will occur if the pouring amount of the content liquid is increased, and when pouring out. It is troublesome because it is necessary to incline the container so that the drinking cup is always on the lower side. When the container is tilted so that the drinking mouth is on the upper side or the lateral side, the pouring direction is uncertain and the pouring liquid is scattered.

The present invention solves the above-mentioned problems of the prior art, that is, which side of the pouring stopper is used when pouring out the content liquid without requiring a troublesome replacement of the lid before the pouring operation of the content liquid. It is an object of the present invention to provide a simple opening lid with a pouring plug that allows smooth pouring of a content liquid even when the container is tilted downward so as not to pulsate greatly.

(Means for Solving Problems) In order to achieve the above object, the simple opening lid with a pouring stopper of the present invention is attached to the neck of the container body, and a circular opening score is provided on the top. A lid having a simple opening mechanism having a tab fixed at one end to a portion surrounded by the opening score; and a resin-integrally-molded pouring plug mounted inside the lid. A spout plug is formed between the upper neck portion of the container body and the lid body, and a sealing portion is formed inside the sealing portion and extends inward from a cylindrical side wall portion and a lower end of the side wall portion. A concave partition wall portion formed of an annular bottom wall, and erected from a bottom wall inner edge portion of the concave partition wall portion,
A cylindrical opening nozzle having a horizontal upper end, and two or more gas / liquid combined openings are provided at sufficient intervals in the lower part of the side wall of the concave partition wall portion. The circular opening score, the cylindrical side wall of the concave partition wall portion, and the cylindrical opening nozzle are concentric circles centered on the center of the lid, and the circular opening score is the cylindrical opening nozzle. It is characterized in that it is located on the outer side than the outer surface of.

(Operation) In the present invention, the spout is preliminarily mounted inside the lid, and the top of the lid is provided with the simple opening mechanism portion including the tab and the circular opening score. Since the consumer operates this tab to break the score part, remove the part surrounded by the score and open it, the content liquid is ready to be poured out.

Also, the cylindrical side wall of the concave partition wall portion of the pouring plug and the cylindrical opening nozzle are concentric circles, and since both are separated by the annular bottom wall of the concave partition wall portion, the inner wall surface of the cylindrical side wall Between the outer surface of the cylindrical opening nozzle and the entire circumference, there is a space of the same width which serves as a content liquid discharge passage or an air suction passage.

Further, in the present invention, the circular shape of the opening score is concentric with the cylindrical opening nozzle, and has a larger diameter than that of the cylindrical opening nozzle, and functions as an outside air inlet into the container and a content liquid outlet to the outside of the container. Since the combined gas-liquid port is provided at the bottom of the side wall of the concave partition wall with sufficient space, the consumer tilted the container so that which side of the pouring plug was facing down. Also, at least one gas-liquid combined port serves as an intake port for sucking outside air into the container from the opening formed in the lid through the space between the opening nozzle and the side wall of the concave partition wall. As a result, the pulsation of the pouring content liquid is buffered and the pouring is performed smoothly.

At this time, even if the content liquid flows out toward the opening nozzle side from the gas-liquid combined opening located on the lower side, the content liquid also flows out from the opening nozzle, so both flows are near the opening of the lid. As a result of merging and unifying, the scattering of the pouring liquid is buffered.

(Embodiment) FIGS. 1 to 4 are views showing a state in which the mouth opening / neck portion of a container body is covered with the simple opening lid with a pouring plug according to the embodiment of the present invention. It is suitable for the lid of the dispensing container for carbonated beverages such as.

First, the structure of the simple opening lid will be described with reference to FIGS. 1 to 3.

This simple opening lid is composed of a lid body 2 which is capped by a screw 4 formed on an outer peripheral portion of a neck portion 1 of a container body, and the lid body 2.
And the spout plug 3 mounted inside by adhesive bonding.

The lid 2 is formed of a plastically deformable metal, and a safety band portion 5 is formed at a lower end of a skirt portion 6 which is screwed and attached to the thread 4 of the container body neck portion 1. . In addition, a lid body 2 that covers the mouth of the neck 1 of the container body
For the purpose of simple opening, the top 7 of the
In addition, the raised portion 11 is formed on the outer peripheral portion of the simple opening mechanism portion 10 for the purpose of protecting the simple opening mechanism portion 10 and preventing upward deformation (bulging) due to the internal pressure of the container. There is. The simple opening mechanism section 10 has a circular opening score 8 concentrically provided with respect to the center of the top section 7.
Is formed by forming a broken portion surrounded by a ring tab 9, and the ring tab 9 is pulled up to remove the broken portion surrounded by the circular opening score 8. The central portion of the top portion 7 of the second portion 2 can be circularly opened.

The spout plug 3 is made of synthetic resin so as to be elastically deformable, and is formed inside the sealing part 13 and a sealing part 13 that is pressed and contacted between the upper neck 12 of the container body and the lid 2. And a concave partition wall portion 14 including an annular bottom wall extending inward from the lower end of the cylindrical side wall 141.
Further, as shown in the sectional view of FIG. 3, at the lower end of the side wall 141 of the concave partition wall portion 14, gas-liquid combined openings 15 are formed at equal intervals, and the concave partition wall portion is formed. At the center of the bottom portion 142 of the portion 14, a cylindrical opening nozzle 17 having a horizontal upper end and a height close to the top portion 7 of the lid 2 is provided upright.
As is clear from the drawing, the cylinders forming the side wall 141 and the opening nozzle 17 are concentric circles. Further, the outer diameter of the opening nozzle 17 is formed smaller than the diameter of the circular opening score 8 of the lid body 2 so that the pouring and suction of the content liquid stored in the container body can be performed without any trouble. There is.

In addition, the spout 3 has a sealing portion 13 and a protruding portion of the lid 2.
11 is adhered to the inner surface of the container, and the lid 2 is attached to the container body neck 1
The sealing portion 13 is appropriately deformed and clamped between the upper neck 12 of the container body and the inner surface of the raised portion 11 of the lid 2 by being screwed onto.

In addition to the bonding, the spout 3 may be attached to the lid body 2 by, for example, a protrusion-like locking ring that protrudes inward from the upper portion of the lid body skirt portion 6.
18 may be provided and the protruding locking ring 18 may be engaged with the sealing outer peripheral edge portion 19 of the spout plug 3.

Next, the operation of the embodiment will be described.

As described above, in the simple opening lid with pouring plug of the present embodiment, the lid body 2 has the circular opening score 8 on the top portion 7 and one end of the ring tab 9 at the break portion surrounded by the opening score 8. Since there is a simple opening mechanism portion 10 to which is fixed and the pouring plug 3 is attached inside the lid body 2 in advance, the consumer is formed on the top portion 7 of the lid body 2 when pouring out the content liquid. It suffices to pull up the ring tab 9 with a fingertip and remove the broken portion surrounded by the opening score 8. As a result, a circular opening 20 larger than the diameter of the outer surface of the opening nozzle 17 is formed in the lid 2.

After that, when the consumer tilts the container body mouth / neck portion 1 downward toward a cup or the like, at least one of the four gas-liquid combined openings 15 is moved upward as shown by an arrow a in FIG. Since at least one of them is located on the lower side, the content liquid is a gas-liquid combined port located on the lower side of the pouring plug 3.
It flows from 15 between the side wall 141 of the concave partition 14 and the opening nozzle 17. Then, the content liquid hits the side wall of the opening nozzle 17 to buffer the flow, and the side wall 141 of the concave partition 14 is formed.
It is poured out of the container from the opening 20 of the lid 2 through the space between the opening nozzle 17 and the opening nozzle 17. At the same time, as shown by the arrow b in FIG. 4, the content liquid also flows into the inside of the opening nozzle 17 and is discharged from the opening 20 of the lid 2 to the outside of the container through the opening nozzle 17. At this time, the side wall 141 of the concave partition 14 and the opening nozzle 1
The content liquid flowing out from between 7 and the content liquid flowing out from the inside of the opening nozzle 17 merge near the opening 20 of the lid body 2 and the flow is unified, so that the content liquid scatters. Is buffered.

On the other hand, when the pressure inside the container becomes negative due to the pouring of the content liquid, the outside air that has passed from the opening 20 between the side wall 141 and the opening nozzle 17 moves upward as shown by an arrow c in FIG. It is inhaled from a part of the gas-liquid combined opening 15 located. Therefore, the pulsation is greatly reduced, and the content liquid can be smoothly poured out continuously.

That is, since the opening nozzle 17 of this example has a cylindrical shape and the upper end is horizontal, it cannot be seen from the outside which side should be the lower side to incline the container, but the outer peripheral surface of the opening nozzle 17 and the concave partition wall The space between the inner peripheral surface of the side wall 141 has the same width over the entire circumference, and also has a gas-liquid communication port that serves as an outside air suction port into the container and a content liquid outlet port to the outside of the container. Since four 15 are provided at equal intervals on the lower part of the side wall 141, no matter which side the consumer inclines with the bottom side, the container is positioned above and serves as the outside air intake port, which is also a gas-liquid combination. Since the through-hole 15 exists and the gas-liquid combined opening 15 which is located on the lower side and serves as the content liquid outlet, the consumer does not need to consider which side should be down.

Since the pouring plug 3 is always attached to the neck 1 of the container body integrally with the lid body 2, there is no risk of loss. Also,
When the container body is reused, the manufacturer collects the container, loosens the screw from the collected container body neck 1 and removes the lid body 2 with the pouring plug 3 attached, and reuses the container body. However, since the sealing portion 13 of the spout 3 serves as a cushioning material to prevent damage to the upper neck 12 of the container body,
The sealing performance can be maintained until reuse. Also,
It is inexpensive because no separate sealing material is required.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and even if there is a design change or the like within the scope not departing from the gist of the present invention, it is included in the present invention. Be done.

For example, in the embodiment, the gas-liquid port of the pouring plug is formed at four locations of the concave partition wall portion at equal intervals, but it may be formed at two or three locations with sufficient spacing, or five You may form in more than one place.

In addition, in the embodiment, the lid is attached to the neck of the container main body by screwing, but by forming a groove on one side and a protrusion on the other side, it is possible to attach by fitting. Good.

Further, the side wall of the concave partition wall portion and the opening nozzle are more effective and more desirable in buffering the scattering and pulsation of the content liquid as they are formed higher.

(Effects of the Invention) As described above, in the simple opening lid with pouring plug of the present invention, the pouring plug is mounted inside the lid body having the simple opening mechanism. The operation at the time is just a simple operation of opening the simple opening mechanism part of the lid top part, and there is no fear of loss of the pouring plug.

Further, since the lid body and the pouring plug after opening are not shaped so as to have a direction such that which side should be tilted downward, it is easy and convenient for consumers to use.

Furthermore, even if the consumer tilts the container with either side of the pouring plug facing downward, pulsation and scattering at the time of pouring the content liquid can be buffered.
