Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a dispensing container that is used by squeezing the container and pouring out or spraying the contents.

[Prior art]

This type of dispensing container is equipped with a content outlet pipe that reaches the bottom of the container at the content outlet provided at the mouth of the container, and when the container is squeezed, the content liquid is pushed up to the outlet via the outlet pipe and poured out. Some are made to come out or be sprayed. This thing is
There is an advantage that the liquid content can be poured out while the container is in an upright position.

However, if such a dispensing container is used to contain a liquid containing a substance such as sodium hypochlorite that splits over time and generates gas as a component, such as toilet cleaner or mold remover, storage problems may occur. The internal pressure of the container increases due to the decomposed gas, and when the container is opened to use the liquid inside, the contents will squirt out due to the internal pressure, and the contents may get into the user's eyes or may come into contact with the user's skin, clothing, etc. There was a risk of it getting stuck.

In order to deal with such problems, the present inventor first published Utility Application No. 59-62354 (Japanese Utility Model Application No. 175057-1987).
proposed a cap with a contents pouring mechanism.

As shown in FIG. 17, this cap with a contents pouring mechanism is slidable along the surface of a cap body 52 provided with an internal pressure adjustment hole 51 and a contents outlet hole 52, and a cap body 53. The container is provided with a variable position stopper 54 which closes the internal pressure adjustment hole 51 and the content outlet hole 52 of the cap body 53 when the container is in the closed state, and the variable position stopper 54 is provided with a through hole 55. When the container is opened, the portion of the cap body 53 where the contents outlet hole 52 is provided communicates with the through hole 55 of the variable displacement stopper 54, and the contents outlet hole 52 is opened to the outside air, and the container is opened. At the initial stage of operation, the internal pressure adjustment hole 51 of the cap body 53 is once communicated with the through hole 55 of the variable position stopper 54. According to this cap, while the variable position stopper 54 is displaced from the closed position to the open position, the internal pressure adjustment hole 51 of the cap body 53 and the variable position stopper 54
The through hole 55 communicates with the outside air and the upper space of the container, and decomposition gas is released and the inside of the container becomes atmospheric pressure, so the contents do not blow out before squeezing, making it safe. be.

[The problem that the idea aims to solve]

However, in this cap, if some of the poured contents remains in the through hole 55, the through hole 55 and the internal pressure adjustment hole 51 will be removed by the next opening operation.
Concerns were raised that the remaining contents could be blown away by decomposition gas inside the container when the container was opened.

This idea was made in view of the above circumstances,
It is an object of the present invention to provide a pouring container with improved safety by releasing decomposed gas without going through a channel through which the contents are led out.

[Means to solve the problem]

The dispensing container of this invention consists of a cap provided with an air vent and a liquid inlet, a container main body containing liquid inside and having the cap attached to the mouth, and a container that slides along the surface of the cap. The opening/closing member is composed of an opening/closing member that is freely provided and is provided with an air vent closing part that closes the air vent of the cap when the container is in a closed state, and a liquid injection opening closing part that closes the liquid injection port. An air vent outside air communication portion is formed between the air vent closing portion and the liquid filling port closing portion of the cap, and the air vent outside air communication portion temporarily communicates the air vent of the cap with the outside air at the initial stage of opening the container. A liquid inlet outside air communication part is formed on the side opposite to the air vent outside air communication part across the liquid inlet closed portion, and communicates the liquid inlet of the cap with the outside air when the container is opened.

[Effect]

However, in such a dispensing container, in the closed state, the opening/closing member closes the liquid inlet and air vent of the cap, so that the liquid inside the container body and the generated gas cannot flow out from the container. do not have.

Then, when the opening/closing member is slid along the surface of the cap in order to pour out the liquid inside the container, the air vent outside air communication part and the air vent temporarily communicate with each other, and the inside of the container body is temporarily opened through them. communicates with the atmosphere. At this time, the gas present inside the container body is immediately released to the atmosphere.

Then, when the opening/closing member is further slid, the air vent is closed again, and the liquid inlet is brought into an open state in which it is opened via the outlet outside air communication section. By squeezing the container body in this state, the pressed liquid content is poured out through the injection port.

〔Example〕

Figures 1 to 4 show an example of the pouring container of this invention.

In FIGS. 1 and 2, reference numeral 1 indicates a container body, and this container body 1 has a bottomed cylindrical shape with an upper portion having a predetermined length and a somewhat reduced diameter. An annular groove 1a is formed on the outer periphery of the upper end of the reduced diameter upper part of the container body 1, and a cap 2 is attached to this groove 1a.

This cap 2 is made of synthetic resin such as polyethylene or polypropylene and is molded into a substantially hemispherical appearance, and the diameter of the circular bottom surface 3 is made equal to the outer diameter of the opening end of the container body 1. Further, a cylindrical hem 4 is formed at the peripheral edge of the bottom surface 3 of the cap 2 and extends downward for a predetermined length, and the lower end of this hem 4 is provided with the groove 1a of the opening of the container body 1. An annular protrusion 4a that engages with is formed. The cap 2 is penetrated from the top to the center of the bottom surface 3, and the container body 1
An air vent 5 is provided which communicates with the inside of the tank. A plug portion 6 is formed at the upper end opening of the air vent 5 and is slightly enlarged in diameter from the top of the cap 2 to a predetermined depth. Further, the cap 2 is provided with a perforation for a predetermined length horizontally from a predetermined position on the outer peripheral surface located at the upper part of the hem portion 4 toward the center, and the tip thereof is opened downward toward the bottom surface 3. A liquid injection port 7 is formed. The inner diameter of the opening 8 of the liquid inlet 7 on the outer peripheral surface side of the cap 2 is approximately equal to the inner diameter of the plug 6 of the air vent 5. On the other hand, a cylindrical portion 9 that protrudes downward by a predetermined length is formed at the periphery of the opening of the liquid inlet 7 on the bottom surface 3 side, and the lower end of the cylindrical portion 9 is near the bottom of the container body 1. The upper end of the content liquid outlet pipe 10 that reaches up to this point is fitted. Furthermore, the above cap 2
A locking recess 11 having the same diameter as the inner diameter of the opening 8 and a predetermined depth is formed at a position diametrically symmetrical to the opening 8 of the liquid injection port 7 on the outer peripheral surface of the liquid injection port 7. There is. As a result, the opening 8 of the liquid injection port 7
The locking recesses 11 are arranged in a line on the outer peripheral surface of the cap 2 in a semicircular arc with the plug 6 of the air vent 5 as its apex. The cap 2 is provided with an opening/closing member 12 for opening or closing the air vent 5 and liquid inlet 7.

This opening/closing member 12 is formed in the shape of a spherical plate that covers a little more than half of the area of the outer peripheral surface of the cap 2, and is provided with a slight gap between it and the outer peripheral surface of the cap 2. Here, the opening/closing member 12 is provided on the outer circumferential surface of the cap 2, with both narrow ends 13, 13 facing in a diametric direction perpendicular to a diametric direction connecting the opening 8 and the recess 11 on the outer circumferential surface. It is being In the opening/closing member 12, in the above position, projections 14, 14 protruding inward from the inner surfaces of both end portions 13, 13 are inserted into holes 15, 15 formed on the outer peripheral surface of the cap 2. . As a result, the opening/closing member 12 uses the protrusions 14, 14 as fulcrums, and the center line of its wide center is aligned with the opening 8 and the locking recess 11 of the stopper 6.
The cap 2 is rotatable along the outer peripheral surface of the cap 2 so as to trace the semicircular arc shape formed by the cap 2 from above. On the lower surface of the wide central part of the opening/closing member 12, the opening and closing member 12 bulges inward at both ends in the rotational direction, and the liquid filling port 7 is opened when the container is in the closed state shown in FIG. A plug body 16 as a liquid inlet closing part that closes the part 8 and a plug body 17 as an air vent closing part that closes the plug part 6 of the air vent port 5.
is formed. An air vent outside air communication portion 60 communicating with outside air is formed between these plugs 16 and 17. In addition, this opening/closing member 1
The space outward from the end edge on the stopper 16 side of No. 2 is defined as a liquid inlet closing portion 61. Further, at the center of the upper surface of the opening/closing member 12, a non-slip portion 18 whose surface is roughened is formed.

However, in such a dispensing container, in the closed state as shown in FIG.
6 and 17 close the opening 8 of the spout 7 of the cap 2 and the stopper 6 of the air vent 5, so that the liquid content and generated gas in the container body 1 do not flow out from the container.

Then, when the opening/closing member 12 is rotated in the direction shown by the arrow in the figure as shown in FIG. 3 in order to pour out the liquid inside the container body 1, the stoppers 16 and 17 are moved between the opening 8 and the stopper. At the same time as leaving 6,
The air vent 5 communicates with the outside air via the air vent outside air communication section 60. As a result, the inside of the container body 1 communicates with the atmosphere via the air vent port 5 and the liquid injection port 7. At this time, the gas generated inside the container body 1 presses the content liquid with a higher viscosity and before being discharged from the liquid injection port 7, the gas is discharged from the air vent 5 as shown by the dotted line arrow in the figure.
It is suddenly opened to the atmosphere.

Then, the opening/closing member 12 is further rotated to open the fourth opening/closing member 12.
As shown in the figure, the plug 17 is engaged in the locking recess 11. Then, the other plug body 16 closes the plug portion 6 of the air vent 5. As a result, the container body 1
The space above the internal contents is closed. On the other hand, the liquid filling port 7 is opened via the liquid filling port outside air communication portion 61, and the container body 1 is placed in an open state. By squeezing the container body 1 in this state, the pressed liquid content is poured out from the opening 8 through the injection port 7.

In this way, in the case of the above-mentioned dispensing container, the opening/closing member 12 is rotated from the closed state of the container body 1 to open the container body 1 at the initial stage of the operation. Since the air vent 5 is open to the atmosphere, the gas generated inside is released from the air vent 5 to the atmosphere. Therefore, before the container body 1 is squeezed, the liquid content will not be spouted out from the liquid inlet 7 due to the gas generated inside.

In this container, the air vent 5 is also
is communicated with the outside air, and the liquid inlet 7 is connected to the outside air communication part 6 of the liquid inlet on the opposite side to the outside air communication part 60 of the air outlet.
1, the liquid inlet 7 and the air vent 5 are communicated with the outside air through separate routes while the opening/closing member is slid. Therefore, it is possible to completely eliminate the conventionally feared accident in which the remaining liquid content flies out when air is removed.

[Other Examples]

FIG. 5 shows a second example of the pouring container of this invention. In the cap 19 of this example, an opening/closing member 20 formed by forming a spherical plate in an L-shape at a predetermined position on its outer circumferential surface is rotatable about a rotation shaft 21 provided at the intersection of its two sides. It is provided. Plugs 24 and 25 are provided on the lower surface of each tip on two sides of the opening/closing member 20 to block the liquid inlet 22 and the air vent 23 provided at the corresponding positions of the cap 19, respectively.
is formed. And these plug bodies 24, 25
The part between the two is an air vent outside air communication part 60. Further, a space on the opposite side from the vent outside air communication section 60 across the stopper 24 that closes the liquid inlet 22 is defined as a liquid inlet outside air communication section 61 . On the other hand, a locking recess 26 is formed on the surface of the cap 19 at a position symmetrical to the liquid injection port 22 with respect to the rotation shaft 21. In the dispensing container of this example, by rotating the opening/closing member 20 by 90 degrees clockwise from the closed state shown in FIG. are opened at the same time, and the gas with good fluidity is discharged first before the content liquid, and then the plug 25 is locked in the locking recess 26, and the plug 24 seals the air vent 23. The structure is such that only the liquid injection port 22 is in an open state.

FIGS. 6 and 7 show a third embodiment of this invention. In this dispensing container, a rectangular parallelepiped opening/closing member 28 slides in the longitudinal direction on the flat top surface 27 of the cap. It is set freely. Plugs 31 and 32 are formed on the lower surface of the opening/closing member 28 to close the liquid inlet 29 and the air vent 30, respectively, which are formed along the longitudinal direction of the cap upper surface 27. The space between the plugs 31 and 32 is an air vent outside air communication section 60. Further, a space on the opposite side of the plug body 31 from the vent outside air communication section 60 is defined as a liquid inlet outside air communication section 61 .

In this container, by sliding the opening/closing member 28 in the direction of the arrow in the figure from the closed state shown in FIG.
The liquid injection port 29 and the air vent 30 are simultaneously opened and air is vented, and the air vent 30 is closed by the stopper 31 at the same time as the open state shown in FIG.

8 and 9 show a fourth example of this invention, and FIGS. 10 and 11 show a fifth example, respectively. In the dispensing containers of these examples, grooves are formed on the outer periphery of the cap 33 formed in a cylindrical shape, one along the vertical direction and the other along the circumferential direction, and an opening/closing member is installed in each of these grooves. 34 and 35 are slidably attached. And both of these opening/closing members 34, 3
5, these plugs close the liquid inlet 36 and the air vent 37 in the closed state, and the opening/closing member 3
4 and 35, both of them are opened once and the air is vented, and then they are opened and the liquid injection port 36 is opened.
The structure is such that only the liquid injection port 36 is opened, and the plug 38 that used to close the liquid injection port 36 closes the ventilation port 37.

Also, Figures 12 to 14 are the sixth figures of this invention.
The dispensing container of this example has an opening/closing member 40 having an elliptical columnar appearance on the upper surface of the cap 39.
is rotatable in the horizontal direction via a rotation shaft 41. In this opening/closing member 40, plugs 44 and 45 respectively close the spout 42 and the air vent 43 of the cap 39 in the closed state. Also, the plug body 44
The space between and 45 is an air vent outside air communication section 60. Further, a space outside the end surface of the stopper 44 on the opposite side from the stopper 45 is used as a spout outside air communication section 61 .

By rotating the opening/closing member 40, this container temporarily opens both the air vent 43 and the spout 42 to vent air, and then enters the open state. The structure is such that 46 is closed.

Therefore, even with the dispensing containers shown in the second to sixth examples, it is possible to obtain the same functions and effects as those shown in the first example.

In the first embodiment, the liquid content outlet tube 10 is inserted directly into the cylindrical part 9 at the bottom of the liquid injection port 7, and when the container body 1 is squeezed, the liquid content is poured out in liquid form. The present invention is not limited to this, and the content liquid outlet pipe 10 may be inserted into the cylindrical portion 9 via a spacer 48 having a groove-shaped jet channel 47 on the inner circumferential surface as shown in FIG. 15, or as shown in FIG. 16. A porous body (for example, a porous material such as a sintered polymer, a mesh, a sponge body, etc.) 49 may be further provided on the top of the above-mentioned spacer 48. Unfortunately, in the case of the one shown in FIG. 15 above, when the container body 1 is squeezed, the gas in the space above the pressed container body 1 is blown out from the fumarole passages 47 into the cylindrical part 9. The liquid can be dispensed in the form of a mist. In addition, in the case of the one shown in FIG. 16, if an activator is mixed in the content liquid, the gas blown from the spacer 48 will cause the content liquid to bubble when it passes through the porous body 49. It can be poured out in a form.

[Effect of idea]

As explained above, the dispensing container of this invention consists of a cap provided with an air vent and a liquid inlet, a container main body containing the liquid inside and having the cap attached to the mouth, and the cap. an opening/closing member that is slidably provided along the surface and is provided with an air vent closing portion that closes the air vent of the cap when the container is in a closed state, and a liquid filling port closing portion that closes the liquid filling port; An air vent outside air communication is provided between the air vent closing portion and the liquid filling port closing portion of the opening/closing member for temporarily communicating the air vent opening of the cap with the outside air at the initial stage of opening the container. As the section is formed,
A liquid inlet outside air communication part is formed on the side opposite to the air vent outside air communication part across the liquid inlet closed portion, and communicates the liquid inlet of the cap with the outside air when the container is opened.

Therefore, according to this dispensing container, even if the content liquid is composed of a substance that decomposes over time and generates gas, the gas inside is released to the atmosphere from the vent port when the container is opened. , the liquid content will not spout out from the injection port.

In addition, in this container, the air vent is communicated with the outside air via the air vent outside air communication part between the air vent closing part and the liquid filling port blocking part, and the liquid injection port is opposite to the air vent outside air communication part. Since the liquid inlet and the air vent are communicated with the outside air through the outside air communication portion on the side, the liquid inlet and the air vent are communicated with the outside air through separate routes as the opening/closing member slides. Therefore, it is possible to completely eliminate the conventionally feared accident in which the remaining liquid content flies out during air removal.
