Description

  The present invention relates to a lid used by being mounted on a kerosene container that can be carried by a person and stored therein, in which the container is tilted and discharged without replacing the lid with a discharging nozzle when the liquid inside the container is discharged. The present invention relates to a structure of a lid having a function of stably performing the pouring.

  There are three types of kerosene containers sold domestically that can be transported by humans, with three capacities of 10 liters, 18 liters and 20 liters, and are mainly made of polyethylene for the purpose of transporting and storing as described above. .

  A structure with a grip on the top and one or more injection outlets beside the grip is common.For convenience in transportation, storage and pouring, the front, flat and side shapes are generally rectangular. Shapes are standardized and are being produced and distributed.

  Containers used for transporting and storing such liquids were originally metal containers that were widely used for transporting and storing oils and chemicals, etc. In order to prevent the corrosion of containers, reduce production costs by mass production, and increase strength, etc., the shapes, capacities, and coloring of containers according to various types of liquids, such as drinking water and drainage, are currently made. Has been put to practical use. A kerosene container is one example.

  Since the kerosene container is intended to contain kerosene, which is a dangerous substance, in order to realize safety, easy transportation and efficient storage, etc., its shape, dimensions, structure and Durability and the like are standardized by JIS.

  As an example, among the 20-litre kerosene containers currently sold in Japan, the one that is widely used is a slightly vertically elongated rounded rectangular shape, which has a grip on the top as described above, and both sides. Has two injection outlets having the same diameter. When the container is placed on the floor, one of the inlets and outlets is vertically upward and the other is obliquely upward.

  The advantage of providing two inlets and outlets of the container is that air can be easily circulated when the liquid is injected into and out of the container, so that the liquid can be smoothly injected and discharged.

  Also, of the two injection outlets provided in the container described above, one of the injection outlets has a shape and structure in which the injection outlet is obliquely upward. This is because the contents can be easily poured out without requiring a large inclination angle when lifting by holding the grip and the container bottom by hand.

  On the other hand, the other injection outlet is oriented vertically upwards because when the container is placed on the floor and the liquid is injected from the lubrication facility of a gas station or another container, the liquid can be easily injected vertically upwards. This is because it is easy to install and use a pump when discharging a liquid from the container using a commercially available pump for discharging.

  The reason why there are many products in which the two inlets and outlets of the container have the same diameter is that both the inlets and outlets can be freely exchanged and used for the outlet nozzle and lid under the same conditions due to the convenience of injection and pouring. .

  On the other hand, the lid of the container is frequently consumed due to deterioration as compared with the main body, and it is necessary to replace the internal gasket or the lid itself with a new one at any time in order to keep the degree of sealing of the container high. In addition, damage due to breakage or loss of the lid or the nozzle for pouring sometimes occurs. At this time, if all of them can be attached and detached in the same size, the minimum number of missing parts may be replenished, which is advantageous in terms of maintenance.

  In the kerosene container having the above-described shape and structure, when the liquid in the container is poured out, depending on the method of pouring, spillage or the like may occur, which may hinder transfer to another container. .

  For example, when a liquid is poured out by attaching a detachable discharging nozzle to the injection outlet of the container, as described above, a person has a gripper at the top of the container and tilts the container in a manner to support the bottom. According to the dispensing method, the liquid can be completely discharged without the liquid remaining in the container, and if the receiving container is provided, the filling operation can be performed without dripping into the container.

  On the other hand, it is not possible for a child, an old man, a woman, or a sick person to lift a container full of contents, tilt the container, and perform the dispensing work while maintaining the posture for a considerable time using a dispensing nozzle. Have difficulty. In such a case, as a frequently practiced method, there is a method in which a pouring pump is separately prepared, and the pouring operation is performed while the container is installed at a certain place.

  At this time, since it is premised that the pouring operation is performed without using the pouring nozzle from the beginning, the work often starts without preparing the pouring nozzle separately.

  However, as a general structural problem of the pump, when the dispensing limit is reached, liquid remains at the bottom of the container. And, in a situation where you do not have a dispensing nozzle attached to the container, as a practical measure, tilt the container directly without attaching the dispensing nozzle and pour out the remaining liquid from the injection outlet to another container. May be transferred to

  At that time, for example, in a general kerosene plastic tank container of 20 liters, even if a person tilts by supporting it and tries to dispense the residual liquid while carefully adjusting the inclination angle, the amount of the liquid suddenly discharged, It is difficult to instantaneously control and limit the speed or splashing of the liquid to be discharged, which not only causes spillage to the vicinity and overflow from the inlet of the receiving container, but also kerosene. It is known that this would waste fuel.

  Because, when the opening of the receiving container is equal to or smaller than the injection outlet of the container to be poured, when the container to be poured is tilted, a large amount of liquid unintended by the worker may be instantaneously wide or wide. This is because it is not possible to properly inject into the receiving container by being spouted from the spout so as to scatter.

  On the other hand, when transferring to a container such as a bucket with a wide opening of the receiving container, the liquid once entering the receiving container may jump or scatter in the container due to the momentum from the situation described above. As a result, it may come out of the container through the wide opening.

  Such a phenomenon that a large amount of liquid is suddenly wide and a part of it is poured out from the spout so that it scatters is easy even if a person tries to dispense by carefully tilting the container by experience measurement. And the amount of liquid wasted due to spills is small compared to the liquid amount of the entire container. Spills out of the liquid ".

  In short, due to the inclination of the container, the residual liquid moves from the bottom of the container all at once to the injection outlet through the side of the container, and during that time, the liquid that has reached the vicinity of the injection outlet without speed buffering or quantitative movement restriction is high. The kinetic energy reaches the recess at the corner of the container in front of the injection outlet, and turbulence when passing through it, some of which are ejected while scattered wide-angle by jumping up, and others are kept in power It is poured out at once.

  In addition, the reason for the rapid large amount of discharge is that the liquid that has moved as a wide path on the side of the container due to the inclination of the container is discharged at an increased flow rate when passing through a narrow portion near the injection outlet, The inconstant flow is closely related to the structure of the container, for example, when the liquid is dispensed, the dispensing width is changed instantaneously and quickly, with the diameter of the injection outlet being the maximum width.

  Looking back, in use of the container, the dispensing nozzle is basically a dedicated component for dispensing liquid, and is one of detachable components. At the time of mounting, the container cannot maintain the hermeticity, so that it is not suitable for transportation and storage except for simple transportation and very short-term storage. As a matter of course, a general screw-type lid having a high hermeticity is generally used for transporting and storing the liquid.

  In other words, when the contents of the container are kerosene in particular, the lid is a part of the container that is indispensable for transportation and storage, and it is a part that is always used by being attached to the container, Since the nozzle is a part that is used by replacing the lid at the time of pouring, the situation where the nozzle for pouring is not prepared at the time of pouring is more frequent than the situation where there is no lid at the work site .

  On the other hand, the kerosene container is tilted by hand, so that it is easy to pour out the liquid inside.Therefore, after using the above-mentioned pouring pump, the kerosene container becomes lighter without attaching the pouring nozzle. It is a common practice in life to lift a container, tilt it, and pour the remaining liquid directly from the spout. If the pouring by that method becomes an appropriate operation, the convenience in life will be improved, and if the content is kerosene, there is no doubt that one step will be taken to counter the waste of fuel.

  By the way, in spite of the above problems, the shape and structure of the spout or its lid under the condition that the container is inclined and the liquid is poured out without installing the nozzle for pouring There are relatively few prior arts invented or devised. Accordingly, prior art documents published in the outline of a method of discharging liquid from a container are listed below and summarized.

  For example, in Patent Literature 1, since the residual liquid concentrates at the inclined portion of the bottom of the container and at the designated location of the suction pipe of the pump for pouring at the bottom of the container, the liquid remaining by the pouring pump is less left unsucked, An approach is shown that requires little subsequent liquid dispensing.

  In addition, for example, in Patent Literature 2, after the use of the above-described pouring pump, the liquid is discharged from a faucet-shaped liquid outlet provided at a lower portion of the container, so that the residual liquid remains in a state where the container is installed. The ways in which it can be dispensed are indicated.

  In addition, for example, in Patent Document 3, the container has a projection-like pouring outlet having a closed lid at the lower portion of the side surface of the container. Is provided so as to be invisible so as to protect the fore-edge which becomes a projection. In addition, there is disclosed a method for enabling the liquid to be discharged from the lower side of the container while preventing the protrusion on the side surface of the container from hindering transportation and storage.

  In addition, for example, in Patent Literature 4, when a liquid is dispensed by tilting the container, a method of dispensing the liquid by inclining the container by attaching a “funnel lid” instead of attaching the dispensing nozzle is described. It is shown.

  In addition, for example, Patent Document 5 discloses a method in which a sealing-type lid is provided at the tip of a pouring nozzle mounted on a container to maintain the sealing property of the container.

  In addition, for example, Patent Literature 6 discloses a lid in which a spout can be selected according to the amount of liquid to be discharged into the container by a two-stage screw-type lid in which a lid of the container has a two-stage structure having a convex shape.

  In addition, there is a product with a simple water supply cock on a lid of a commercially available water supply plastic tank.

Japanese Industrial Standard (JIS Z1710: 2012 Body 01 Polyethylene can for kerosene) Blow molded polyethylene containers for kerosine

  The problem to be solved in the present application is that in a kerosene container that can be transported and stored by a person, when the liquid inside the container is poured out by tilting the container, it is stable without separately mounting an injection nozzle at the injection outlet. It is an object of the present invention to provide a lid of a container which has a built-in spout having a structure and a function capable of effectively discharging liquid from the container and which maintains the hermeticity and strength of a conventional lid.

  First of all, the meaning of "can stably discharge liquid from the container" means that the liquid to be poured can be prevented from suddenly increasing rapidly and in large quantities, and that the liquid can be prevented from being scattered at a wide angle. , And that the width of the liquid to be dispensed can be limited within a certain range.

  For example, in Patent Literatures 1, 2, and 3, it is possible to reduce the unsucked liquid by a pump, and to allow subsequent liquid pouring from a small opening provided at the lower part of the container as shown in Patent Literatures 2 and 3. It is. The method is different from the method of solving the problem of the present application in that the operation of injecting the liquid by tilting the container is not required.

  In addition, for example, since the spout present at the lower part of the container in Patent Documents 2 and 3 has a structure that is always in contact with the liquid inside, the pressure inside the container during the transportation or storage of the liquid, the deterioration of the gasket, etc. However, there is a problem in maintaining the hermeticity, in which liquid leakage easily occurs from the site. In addition, the method differs from the method of solving the problem of the present application in that it does not involve the operation of injecting the liquid by inclining the container as in Patent Document 1.

 In addition, for example, in Patent Literature 4, although performing the liquid pouring operation by inclining the container without using the pouring nozzle is consistent with the prerequisite for the solution of the problem to be solved in the present application described later, it is difficult to transport and store the liquid. The method of exchanging the lid with a funnel-covered lid, attaching and pouring, has no clear difference from the conventional method of replacing the lid with a pouring nozzle, attaching and pouring work, I can't solve it.

  In addition, for example, in Patent Document 5, the sealing performance is improved by providing a lid at the tip of the pouring nozzle, and by replacing it with a normal lid, it is possible to transport and store it while attached to a container. The outlet nozzle is always attached to the container. However, there is a problem that it is necessary to maintain “the strength of the lid” to be described later in order to function as a lid of a highly airtight container while maintaining the flexibility of the pouring nozzle.

  For example, if the method according to Patent Document 6 is applied to a lid of a kerosene container, the width of the flow which is a part of securing the hermeticity of the lid and stabilizing the flow at the time of discharging the liquid, which is part of the problem of the present application, is described. May be restricted. However, when such a lid is mounted on the container and tilted, the problem of the present application cannot be solved because the lid does not have a buffer function for restricting the flow velocity of the liquid to be poured and the sudden discharge due to the turbulence of the liquid.

  In addition, there is a product with a simple liquid pouring cock in the lid of a commercially available water supply plastic tank and the attached lid of an 18 liter can of soy sauce, which are the same as those exemplified in Patent Documents 2 and 3. In addition, since there is a problem in securing the tightness and strength of the lid relating to measures against liquid leakage during transportation and storage, the problem of the present application cannot be solved at present because the lid is not suitable for a component serving as a lid of a kerosene container.

  By the way, according to Japanese Industrial Standards shown in Non-Patent Document 1, regarding the “polyethylene can for kerosene”, one of the purposes of maintaining safety, sealing property and durability is to determine the diameter and number of injection ports, and a lid is a gasket. Standards have been established to maintain the hermeticity of the interior of the vehicle and to conduct a lid strength test and the like.

  In addition, regarding the location of the inlet and outlet and the detailed shape of the lid that are not specified in the specification, the product has a shape and structure that can withstand the strength test in consideration of economy and safety when using the product as far as it is commercialized It seems that what they are doing is becoming common sense in the industry.

  The problem in the present application and the current state of the prior art have been described above.

  In order to solve the above-described problems, the present application incorporates a highly sealed and strong spout used for ordinary transportation and storage of a kerosene container, based on the above various prior arts. The ability to perform the pouring operation using the lid, to mitigate the sudden and large volume of the liquid to be poured when pouring the liquid by tilting the container, and to limit the width of the liquid to be poured A spout that has a structure and function that can stabilize the pouring of the liquid discharged from the kerosene container by stabilizing the flow, making it constant flow, and narrowing the width by suppressing the spout that scatters at a wide angle. It is an object of the present invention to provide a lid for a kerosene container having a built-in.

  The main means adopted by the present application is characterized by having the following configuration, function and effect.

As shown in Claim 1, the basic structure of the entire lid , including the original lid, the small lid, and the buffer filter , shall be used for the lid to be mounted on a kerosene container that can be carried by a person and store the contents .
The main lid, the small lid and, if necessary, the lid to be used in the third and subsequent stages are provided in a multi-stage form,
A convex small spout that can be screwed into the small lid is provided on the original lid.
Has a built-in gasket to maintain the tightness of the small spout,
A smooth flow path that smoothes the convex step is provided inside, and
A buffer filter is installed at the boundary with the kerosene container, and the buffer filter
So that the total area of the small holes is larger than the cross-sectional area of the small spout
With the structure provided, the width can be reduced by extracting the liquid from the small outlet on the step
To use a small lid with a built-in gasket to seal the small spout.
To maintain the tightness of the entire lid more, smooth flow path smoothing the convex step inside the lid
Turbulence when the liquid passes through the location toward the dispensing outlet
Control the generation and install a buffer filter at the boundary with the kerosene container.
Then, the flow rate of the liquid moving in the kerosene container toward the injection outlet is restricted, and the liquid is transferred.
Turbulence generated in the kerosene container during operation
Temporary storage of liquid in the smooth channel due to the difference between the amount of liquid passing and the amount of liquid discharged from the small pouring outlet
With a function to achieve a constant flow of liquid discharged from the small pouring outlet
Solve the problem.

According to the second aspect of the present invention, the small spout outlet is surrounded by a wall extending the height of the original lid, and the structure and function of protecting the small lid and the small spout by the height and thickness of the wall are provided. In order to solve the problem, the external strength of the lid and the small spout of the kerosene container described in claim 1 is maintained.

The lid of the kerosene container referred to in claim 1 has a threaded groove on the inside and an original lid that is aligned with the injection outlet of the kerosene container, and has a thickness of the same material, which is equal to or greater than that of the original lid, so as to overlap the original lid. It is basically composed of a small spout with a screw groove on the outside that protrudes in a shape, and a small lid with a built-in gasket that functions to fit into the small spout. It is characterized in that it has a structure in which a smaller spout is superimposed in the same manner.

  At this time, the planar arrangement of the small spouts provided in a multi-stage shape on the base lid is concentric with the opening of the base lid.

  Further, the buffer filter according to claim 1 is disposed at a boundary between the inlet and the outlet of the kerosene container and the lid, the filter being a first buffer filter composed of a flat plate having a plurality of small holes, and smaller than the first buffer filter. A second buffer filter having a flat plate or a hole at a position where liquid cannot pass linearly from the hole of the first buffer filter, which is disposed in parallel with a certain space on the spout side, and the same is necessary hereinafter Is a multi-stage filter that adds the number of filters according to.

  The first buffer filter has a structure in which the total area of the plurality of small holes is slightly larger than the cross-sectional area of the small spout.

Also the smoothing passage in the claims 1, located between the buffer filter and a small spout, lighting
The flow path is characterized in that corners are removed from the corners of the inner wall generated by the steps caused by the shape of the lid of the oil container and smoothed.

By the way , the base lid , the small lid, and the lids used after the third step as required in the kerosene container lid shown in this application are all screw-in and gasket built-in, and have the same structure as the conventionally used kerosene container lid. It has a mounting structure, and the small spout and the spouts in the third and subsequent stages that are installed as necessary have a thickness equal to or greater than the original lid.

Next, due to the effect of the kerosene container lid of the present invention in the transportation and storage of the kerosene container , and the inclination of the kerosene container during liquid injection, the liquid moves through the kerosene container to reach the small spout and the buffer described above. The effects of the filter, smooth flow path, and small spout will be described sequentially.

First, the kerosene container lid presented in this application has the same mounting structure as that of the conventionally used kerosene container lid, which is screwed and built-in gasket as described above, and the pipe that forms the small discharge port is the original lid. Having a thickness equal to or greater than that of the cover has the effect of maintaining the tightness and internal strength of the entire lid and preventing liquid leakage due to the internal pressure of the container during transportation and storage.

  Next, in the kerosene pouring operation, the liquid that moves inside the kerosene container due to the inclination of the kerosene container and reaches the injection outlet increases its flow velocity at the initial stage of the movement, and flows when passing through the concave wall surface inside the container just before the injection outlet. Depending on the shape of the road, a part of the road may be scattered or waved by jumping, causing turbulence, and the other part of the road may be sudden. Then, depending on the amount of liquid remaining in the container, a large amount of liquid may temporarily head toward the injection port with the same tendency.

  The liquid at that time is first passed through a first buffer filter having a plurality of small holes of the buffer filter inscribed in the lid, thereby limiting the flow rate. Then, the liquid that has passed through the small holes of the filter collides with the wall surface of the second buffer filter and reaches the smooth flow path, whereby the velocity and turbulence are suppressed and the flow is made static. However, when the static flow of the second buffer filter is insufficient, the static flow can be promoted by providing a third buffer filter parallel to the second buffer filter on the small spout outlet side.

When the liquid is passed through the smooth flow path, the above-described static flow is maintained by passing the liquid through the smooth surface of the flow path, and the sudden flow is suppressed by guiding the liquid to the small outlet. In addition, since liquid within a certain width that matches the width of the small pouring outlet can be discharged to the outside, it is compared with the liquid that is discharged from the filling outlet of the kerosene container without the lid of the kerosene container shown in this application . At this time, the liquid to be poured can be narrowed.

  Further, if the liquid is continuously discharged from the small outlet, the liquid is temporarily stored in the smooth flow path gradually due to the supply-demand relationship between the liquid passing through the hole of the outer buffer filter and the amount of liquid discharged from the small outlet. Therefore, there is an effect that the liquid which has been made to flow at a constant flow rate is discharged from the outlet.

  In addition, with the provision of the buffer filter described above, the liquid temporarily stored in the smooth flow path is reduced in pressure received from the residual liquid in the container, and can maintain the pressure. Until the pressure decreases after passing through, a constant flow at the time of pouring can be maintained.

  On the other hand, in the second aspect, the small spout is surrounded by a wall extending the height of the original lid, and the height and the thickness of the wall make the small lid and the small lid mainly due to an external force applied to the lid from the horizontal direction. By providing a role of a protective wall for avoiding breakage of the spout, the structure is made to be able to oppose external force, thereby maintaining the external strength of the small lid and the small spout.

According to claim 1 of the present application, in the lid designed to be installed in the kerosene container can store contents were transported person, to achieve narrowing of the pouring liquid by its structure, the tube forming small spout By having a thickness equal to or greater than the original lid and using a small lid with a built-in gasket to seal the small spout, it is possible to maintain the tightness and internal strength of the entire lid. By the function of the buffer filter provided inside the lid, the flow velocity and the flow rate of the liquid moving in the container can be restricted, and the turbulent flow generated in the container can be reduced. Then, the force applied to the liquid stored in the smooth channel can be made constant. Further, due to the structure of the smooth flow path, turbulence of the liquid passing through the location can be suppressed. Due to these effects, it is possible to realize static and constant flow of the liquid discharged from the small pouring outlet.

  According to the second aspect of the present invention, a structure is provided in which the periphery of the small spout is surrounded by a wall extending from the height of the original cover, and the small lid and the small spout are protected by the height and thickness of the wall. Thus, the external strength of the lid can be maintained.

External view of kerosene container two-stage lid Sectional view of kerosene container two-stage lid Buffer filter Liquid flow in the multistage lid during pouring

  A mobile phone for carrying out the present application will be described below. In the present embodiment, a 20-liter plastic tank for kerosene is used as the container.

FIG. 1 shows an example of a kerosene container lid with a two-stage lid in the present application. In (a) which is a plan view, a small lid 101a is provided concentrically with the original lid 102a mounted on the container, and a small lid protection wall 103a is arranged around the small lid 101a. In (b) which is a front view, the height of the original lid 102b is increased by the small lid protection wall 103b which is an extension of the height of the original lid 102b.
The height of the protective wall is equal to the height when b is completely mounted, and the thickness of the protective wall is set to be three times the pipe thickness of the small spout to surround the small lid 101b. Therefore, the presence of the small lid 101b cannot be confirmed from the horizontal direction.

  FIG. 2A is a plan view of the two-stage lid in the present application, and FIG. A two-stage lid provided with a convex small spout 209b into which a small lid 201b containing a gasket can be screwed, on the original lid 202b, and the original lid 202b is a female screwed portion 204b which matches the screwed convex portion of the plastic tank injection outlet. And a gasket 212b for sealing, and has a structure in which the inside reaches a small outlet 209b through a smooth flow path 205b. Then, a buffer filter composed of the first buffer filter 206b, the second buffer filter 207b, and the fixed spacer 208b is disposed at the lower part of the original cover at the boundary with the kerosene container.

  FIG. 3 is a side view (a) of the buffer filter described above and a plan view (b) of the buffer filter viewed from the first buffer filter 306a side. The first buffer filter 306b and the second buffer filter 307b are arranged concentrically in a plane, have a double structure in which both buffer filters are fixed to each other by a fixing spacer 308a, and a fixed space is provided between the two filters. Further, as shown in FIG. 2B, the first buffer filter 206b is installed and fixed at the buffer filter installation site 211b inside the original lid. The first buffer filter 306b of FIG. 3B has a structure in which a plurality of small holes 309b are uniformly provided, and the total area thereof is 1.5 times the cross-sectional area of the small spout 209b shown in FIG. . Further, the second buffer filter in this example has a structure having no hole.

  When transporting using the kerosene container according to the present example, the projecting portion of the small lid 201b shown in FIG. 2 is hidden by the small lid protecting wall 203b, so that it does not hinder the transportation, and also when loading and unloading to a truck or the like. In addition, even when the bottom or side surface of another container comes into contact with the small lid protective wall 203b of the lid of the container and an external force is applied to the entire lid, the small lid 201b is not contacted with the projecting portion of the small lid 201b. By protecting, the external strength of the lid could be maintained. Also, in the case of a change in the internal pressure of the container due to a temperature change or the like during the storage of kerosene, the ejection or leakage of the liquid near the female screw 204b inside the base lid and near the gasket in the small lid 201b corresponding to the male screw at the kerosene container inlet / outlet is not affected. It was possible to keep a sealed state without any. Further, there was no crack in the lid due to internal pressure or the like in the container, and there was no liquid leakage from the lid surface due to the crack, and the internal strength could be maintained.

  Next, when the kerosene container 405 in this example is inclined to inject a liquid, the inclination angle of the container is substantially as shown in FIG. The liquid that moves in the kerosene container 405 due to the inclination of the kerosene container 405 and reaches the injection outlet reduces its flow velocity due to the quantitative passage restriction in the hole of the first buffer filter 402 and the effect of collision with the second buffer filter 406, and All of the turbulent liquid, which is scattered by jumping and wave-like generated when passing through the inner wall surface 408 of the container in front of the container injection outlet, also passes through the hole of the first buffer filter 402 and Was mitigated by a collision. Thereby, the flow of the liquid could be made static.

  When the liquid that has been made to flow is passed through the smooth flow path 403 and passes through the smooth surface of the flow path, it is guided to the small spout 407 while maintaining the above-mentioned static flow. It was possible to suppress sudden pouring due to a high liquid pressure. Also, the liquid within a certain width matching the width of the small pouring outlet 407 could be poured out. As compared with the liquid discharged from the injection outlet of the kerosene container without mounting the two-stage lid in this example, the width of the discharged liquid could be reduced.

  Further, when the liquid pouring from the small pouring outlet 407 continues for a while, the supply and demand relationship between the liquid passing through the hole of the first buffer filter 402 and the amount of the liquid 404 pouring out from the small pouring outlet 407 gradually smoothes the liquid. The effect of temporarily storing the liquid in the channel 403 was observed. As a result, it is possible to realize a constant flow liquid discharge that is not interrupted from the discharge port 407.

  Note that, due to the effects of the above-described buffer filters 402 and 406, the pressure temporarily received from the residual liquid 401 in the container is reduced in the liquid temporarily stored in the smooth flow path 403, and it is possible to maintain the pressure. Until all of the liquid inside passes through the first buffer filter 402 and its pressure decreases, the static and constant flow of the liquid discharged from the small discharge port 407 can be maintained, and then the liquid is gradually discharged. The liquid could be reduced to complete the dispense without dripping.
