Description

The present invention relates to a pouring container that pours out the contents by tilting the container.

Conventionally, a pouring container for pouring out the contents by tilting the container and having a structure for separating the air flowing in with the pouring from the contents is known.
For example, an injection adapter (stable injection) having an intake hole (air intake port 5) and a communication hole (wine outlet port 8) and having an isolation film (bag-shaped diaphragm 1) connected to the intake hole (air intake port 5). A pouring container in which a container) is attached to a pouring outlet of a pouring container so that a separating film (bag-shaped diaphragm 1) is housed in the pouring container is known in Patent Document 1. The pouring container known in Patent Document 1 further has a check valve (ball 6, ball stopper 7) at the tip of the communication hole (wine outlet 8), and the contents can be obtained by tilting the pouring container. When the (wine 10) is taken out, the air that is about to flow into the pouring container is taken in through the intake hole (air intake port 5), so that the isolation film (bag-shaped diaphragm 1) inflates due to the air taken in and the pouring container. It fills the space where the contents (wine 10) are taken out. As a result, air does not come into direct contact with the contents (wine 10) remaining in the pouring container, deterioration of the contents (wine 10) can be prevented, and the communication hole (wine outlet 8) can be prevented from deteriorating. Since air does not pass through the wine, it is possible to prevent pulsation when the contents (wine 10) are taken out.

Patent Publication No. 2-57567

However, the dispensing container known in Patent Document 1 still has room for improvement. That is, since the isolation film (bag-shaped diaphragm 1) is provided on the dispensing adapter (stable dispenser), the isolation film (bag-shaped diaphragm 1) that swells by taking in air covers the area around the mouth of the dispensing container. There was a risk of blocking and hindering the removal of the contents (wine 10).

When the pouring adapter (stable pouring device) is attached before filling the content (wine 10), the content (wine) is provided through the communication hole (wine outlet 8) provided in the pouring adapter (stable pouring device). Since 10) is filled, it takes longer than filling without the pouring adapter (stable pouring device) attached, and there is a risk that the production speed may decrease.
In addition, when the pouring adapter (stable pouring device) is attached after filling the contents (wine 10), the amount of the pouring adapter (stable pouring device) and the isolation film (bag-shaped diaphragm 1) that enter the pouring container is increased. There is a risk that the contents (wine 10) will overflow from the pouring container, and even if the contents (wine 10) are filled in an amount that does not overflow in advance, the creases of the shrinking isolation film (bag-shaped diaphragm 1) There was a risk that air would be caught in the contents (wine 10) and mixed in the contents (wine 10).

In addition, since the communication hole (wine outlet 8) has a small diameter and the container needs to be tilted greatly when the content (wine 10) is taken out, if a very small amount of the content (wine 10) is to be taken out, a pouring container is used. There was a risk that more than the required amount of contents (wine 10) would be taken out only by adjusting the tilting angle.

The present invention solves these problems. With a simple structure, the isolation film does not hinder the removal of the contents, and the filling speed is reduced or the contents leak from the pouring container at the time of plugging. The purpose is to provide a pouring container that is free of charge.

The pouring container of the present invention has a mouth portion provided with a spout for pouring out the contents, a body portion extending downward from the mouth portion, and a bottom portion extending downward from the body portion. A pouring container for pouring out contents by tilting, the bottom of which has an intake hole and an intake valve capable of opening and closing the intake hole, and the pouring container is provided through the intake hole. It further has an isolation film that communicates with the outside to form an air chamber , the bottom portion having a bottom wall portion and a bottom surface connected to the lower end of the bottom wall portion, and the bottom surface has a convex bottom surface that rises upward. A portion is formed, and the intake valve can be opened so as to allow the inflow of outside air from the intake hole to the air chamber, and can be closed so as to prevent the outflow of gas from the intake hole to the outside of the container. It is a check valve, and the isolation film is connected to the top surface of the intake valve near the center of the isolation film, and the outer peripheral edge portion of the isolation film is all around the rising portion of the bottom wall portion from the bottom surface. By being connected over , the above-mentioned problem is solved.

According to the injection container according to claim 1, the intake hole and the intake valve that can open and close the intake hole are provided at the bottom, and are isolated so as to communicate with the outside through the intake hole to form an air chamber. By further holding the film, the isolation film is provided in the dispensing container before filling the contents without interfering with the mouth of the dispensing container and hindering the filling of the contents. Therefore, even if the mouth of the pouring container is plugged, the contents will not overflow.
In addition, when the contents are taken out from the pouring container, the voids generated in the pouring container due to the contents being taken out are filled by taking in outside air from the intake hole into the air chamber, so that the mouth of the pouring container is filled. Air flows in from the air, and the contents do not come into direct contact with the air, so that deterioration of the contents can be prevented.
In addition, since the intake hole is provided with an intake valve that is a check valve that can open and close the intake hole, the intake valve is closed when the required amount of contents has been taken out and the pouring container is left to stand. As a result, even if the contents press the swollen isolation film, the air in the air chamber does not flow out of the injection container from the intake hole.
Further, by forming a bottom convex portion that rises upward on the bottom surface of the bottom portion, a concave space can be provided on the lower surface side of the bottom surface, whereby the intake valve is positioned so as not to protrude below the lower end of the bottom surface. Since it can be provided, the pouring container can be stably upright without interfering with the intake valve, and erroneous operation of the intake valve can be prevented.
Further, since the isolation film is connected to the bottom, the contents do not stay under the isolation film, and it is possible to prevent the flow path from being blocked by the isolation film when the contents are taken out.
Further, since the isolation film is connected to the intake valve, the contents of the incompressible fluid always exist near the intake valve, and when the contents are taken out from the pouring container, the intake valve of the isolation film is used. Since the part connected to the air intake valve quickly follows the movement of the contents and operates the intake valve in the opening direction quickly, until the intake air is started in the air chamber as compared with the case where the isolation film is not connected to the intake valve. Response speed can be improved.
In addition, since the outer peripheral edge of the isolation film is connected to the rising portion of the bottom wall portion from the bottom surface over the entire circumference, a large gap for the contents to slip under the isolation film does not occur, and the pouring container is used. Even if the contents inside are reduced, the isolation film does not further block the flow path for taking out the contents, and the entire amount of the contents can be surely taken out from the pouring container.

According to the configuration according to claim 2 , the intake valve includes a pressure plate formed in a flat plate shape having a diameter larger than that of the intake hole, and a sliding portion that protrudes from the center of the pressure plate and allows the intake hole to slide. Since it has an urging member that urges the pressure plate and the sliding part in the closing direction, the intake valve functions as a check valve, and when the required amount of contents is taken out, the urging member causes it. By closing the air intake hole quickly, even if the contents press the isolation film, it is possible to prevent the air in the air chamber from flowing out of the pouring container.

According to the configuration according to claim 3 , at least the portion including the bottom portion is configured as a separate body from the portion including the mouth portion, and therefore, when the isolation film or the intake valve is attached to the bottom portion, the portion passes through the narrow mouth portion. It can be attached directly to the bottom without any effort.

According to the fourth aspect, since the outer peripheral surface of the sliding portion is provided with a ventilation groove extending from the pressure plate in the projecting direction, intake air can be taken more quickly.

According to the configuration of claim 5 , the tip of the sliding portion is provided with an opening button having a diameter larger than that of the intake hole and capable of pressing the intake valve from the outside of the intake hole in the opening direction. By pressing the opening button when filling the contents, the contents can be sufficiently filled in the pouring container while discharging the air in the air chamber.

According to the configuration of claim 6 , the spout is provided with a spout adapter that fits into the spout, and the spout adapter communicates with the inside and outside of the spout container and has a diameter smaller than the inner diameter of the spout. Since the communication holes are provided, it is possible to prevent the inflow of air from the communication holes when taking out the contents.

Further, a notch 133 is formed at the end of the engaging cylinder 135 on the intake hole 125 side of the opening button 132.

As shown in FIG. 5, the inside of the pouring container 100 is provided with a storage chamber 115 for filling and storing the contents S and an air chamber 116 for holding the outside air A taken in from the intake hole 125. The air chamber 116 is separated from the air chamber 116 by an isolation film 117 formed in the form of a thin film.
In the isolation film 117, the vicinity of the center is connected to the top surface of the pressure plate 127, and the outer peripheral edge portion is connected to the rising portion of the bottom wall portion 121 from the bottom surface 123 over the entire circumference. The connection method between the two is preferably adhesion or welding.

Next, the filling of the content S into the pouring container 100 will be described with reference to FIG.
First, the filling nozzle (not shown) is aligned with the spout 112 of the mouth portion 111, and the content S is filled into the storage chamber 115 of the pouring container 100 as shown in FIG. 6A.
At this time, the pouring adapter 140 is not yet attached to the pouring outlet 112, and the pouring outlet 112 has a larger opening than the communication hole 141, so that the content S can be filled quickly.

Further, since the lower connection portion 114 is press-fitted with the upper connection portion 122 to connect the boundary between the container upper portion 110 and the bottom portion 120 without a gap between the container upper portion 110 and the bottom portion 120, the pouring container 100 Even if the content S is filled inside, the content S does not leak out of the pouring container 100 from the connection portion between the top 110 and the bottom 120 of the container.
Further, when the outside air A has flowed into the air chamber 116 before the content S is filled, the filled content is filled by pressing and opening the opening button 132 of the intake valve 126 during the filling of the content S. The air chamber 116 is pressed through the isolation film 117 by the object S, and the excess outside air A in the air chamber 116 can be discharged from the intake hole 125 to the outside of the pouring container 100. As shown in FIG. 6B, a predetermined amount can be discharged. The contents S of the above can be reliably filled in the storage chamber 115 without overflowing to the outside of the pouring container 100.

After filling the storage chamber 115 with a predetermined amount of the content S, as shown in FIG. 6C, the pouring adapter 140 and the sealing stopper 142 are fitted to the pouring outlet 112 to fill the pouring container 100. The filling of the contents S and the sealing of the pouring container 100 are completed.

Next, the removal of the content S from the pouring container 100 will be described with reference to FIG. 7. For the sake of explanation, the drawing of the pouring container 100 as it is left standing is used.
First, when the sealing stopper 142 is removed from the pouring adapter 140 and the pouring container 100 is tilted, the content S passes through the communication hole 141 by its own weight and is taken out of the pouring container 100.

At this time, since the inside of the pouring container 100 is in a negative pressure state due to the extraction of the contents S, a force for sucking the outside air A is generated, but the pouring outlet 112 narrows the opening area by the communication hole 141. Since the intake valve 126 is opened by the force that tries to suck the outside air A, the outside air A does not flow into the storage chamber 115 from the mouth 111 side, and as shown in FIG. 7A, air does not flow into the storage chamber 115. The outside air A flows into the chamber 116 only through the intake hole 125 (ventilation groove 130) of the bottom 120.
As a result, since the outside air A does not come into direct contact with the contents S in the storage chamber 115, deterioration of the contents S in the storage chamber 115 can be prevented.

Further, since the central portion of the isolation film 117 is connected to the pressure plate 127, when the content S is an incompressible liquid, the content S always exists up to the vicinity of the pressure plate 127, and the content S is poured. When the container 100 is taken out of the container 100, the pressure plate 127 quickly follows the movement of the content S through the isolation film 117 to quickly operate the intake valve 126 in the opening direction.
As a result, the response speed until the start of intake air into the air chamber 116 can be improved as compared with the case where the isolation film 117 is not connected to the pressure plate 127.
Further, an annular closing ring 128 projecting downward is provided on the outer peripheral edge of the pressure plate 127 of the intake valve 126, and the sliding portion 129 of the intake valve 126 faces the protruding direction from the pressure plate 127. Since the ventilation groove 130 is provided, the intake hole 125 is opened by the ventilation groove 130, and the intake valve 126 can be opened and closed only in the contact state between the closing ring 128 and the bottom convex portion 124. , The intake valve 126 can be opened and closed more quickly with respect to the operation of the pressure plate 127.

Further, after the intake valve 126 is opened, the outside air A is quickly replenished from the intake hole 125 (vent groove 130) every time the content S is taken out, so that the inflow of the outside air A from the communication hole 141 can be prevented more reliably. , It is possible to prevent pulsation when the content S is taken out.
Further, since the notch 133 is provided at the end of the engaging cylinder 135 on the intake hole 125 side of the opening button 132, even if the bottom convex portion 124 and the opening button 132 are in close contact with each other during intake, the opening button 132 is cut. It is possible to take in air from the notch 133 to the air chamber 116, and it is possible to prevent the outside air A from being taken into the storage chamber 115 from the communication hole 141 due to an unexpected blockage of the intake valve 126 such as pushing the opening button 132 too much. ..

When the content S is further taken out of the pouring container 100, as shown in FIG. 7B, the isolation film 117 is inflated by the taken-in outside air A, so that the volume of the storage chamber 115 is reduced and the volume of the air chamber 116 is reduced. The volume expands.
At this time, the isolation film 117 is connected to the top surface of the pressure plate 127 near the center and the outer peripheral edge portion is connected to the rising portion of the bottom wall portion 121 from the bottom surface 123 over the entire circumference. Since a large gap for the contents S to slip under the 117 does not occur, the isolation film 117 blocks the flow path for taking out the contents S even if the contents S in the pouring container 100 are reduced. The entire amount of the content S can be reliably taken out from the pouring container 100.

Further, even when the entire amount of the content S is stored in the storage chamber 115 without being taken out from the pouring container 100, the content S presses the air chamber 116 through the isolation film 117, as shown in FIG. 7 (c). As shown, the intake valve 126 is urged in the closing direction by the urging force of the closing spring 131 and the weight of the content S received by the pressure plate 127 through the isolation film 117 unless the opening button 132 is continuously pressed. Therefore, the outside air A that has flowed into the air chamber 116 stays in the air chamber 116 and holds the volume of the air chamber 116.
As a result, the volume of the storage chamber 115 does not increase, and even if the pouring container 100 in which the content S remains is left standing without fitting the sealing plug 142, the inside of the storage chamber 115 through the communication hole 141. The outside air A is not taken into the air.

The required amount of the content S is taken out from the pouring container 100, the pouring container 100 is allowed to stand, and then the communication hole 141 is press-fitted into the communication hole 141 to close the communication hole 141, and then the content. Until the opportunity to take out S, the contents S in the storage chamber 115 can be safely stored without touching the outside air A.
