Definitions
- This invention involves a container for preserving liquid or gelatinous material inside. It especially relates to structures of a lid equipped with a discharge mouth that guides fluid from the inside to the outside and to a container equipped with the lid.
- the conventional structure of a container for preserving liquid or gelatinous material fails to prevent air from flowing into the inside of the container, especially when the fluid content is discharged through the discharge mouth. This causes the content to become oxidized, and the remnant of the content remaining around the discharge mouth cannot be prevented from entering the inside of the container, resulting in degradation or deterioration of the content of the container.
- Patent Document 1 JP Patent No. 3492600
- Patent Document 2 JP Utility Model Publication No. 58-021399
- an inflow of air intends to be checked by a valve which can be opened or closed depending on a pressure level of the inside of the container.
- the valve can open with increased pressure inside of the container, for instance, when a user manually puts pressure on the container outer shell made of flexible material, and can close when he or she releases the pressure.
- the container structure listed in Patent Document 1 comprises a tubular outer shell of a container that made of flexible material with a discharge mouth, an inside plug that shuts the discharge mouth with the central part protruding toward the outside, passages equipped with the inside plug that connect the inside of the container to the outside, and a nozzle portion surrounding part of the discharge mouth, made of elastic resin or rubber, and intimately contacted with the outside surface of the inside plug.
- the addition of pressure to the container shell increases a level of the inside pressure of the container that results in the nozzle portion swelling as a result of its elasticity, making space between the inside plug and the nozzle portion that causes the contained fluid to discharge.
- Patent Document 1 works as such.
- the elasticity of the nozzle portion material enables the discharge mouth to open and close.
- the characteristic of the invention depends only on the elasticity of the nozzle portion material.
- the elasticity alone is not sufficient to produce between the plug and the nozzle portion a space to help fluids be discharged from the container.
- the elasticity in turn prevents the nozzle portion from having sufficient intensity to secure airtightness. Airtightness could be incurred when an unintentional handling of the nozzle portion mistakenly triggers the nozzle part to deform or get disconnected.
- the nozzle portion of the container has the V-curve area, which in practice makes it impossible to automatically return to the original position after making the discharge mouth open.
- a lid portion is equipped with the neck portion of the container that closes the opening of the neck, comprising a cylinder with a discharge mouth in the center, and a plug equipped with a piston intimately contacted from inside of the cylinder.
- the plug and the piston remain raised up from below inside toward the discharge mouth.
- the addition of pressure to the container shell increases an internal pressure level of the container that results in the piston moving away from the mouth owning to the pressure inside of the container, triggering fluids to discharge with the plug detached from the discharge mouth. With the pressure inside of the container decreased, the cylinder returns to the original position, causing the plug to close the discharge mouth.
- the structure is complex and costly to produce, and there is a possibility that fluids may remain in a space between the cylinder and the piston, preventing a normal operation or causing irregularities.
- Patent Document 1 is structured to require pressure to be added on the outer shell of the container in order to make contained fluid to discharge through the discharge mouth
- its utility value as a container for storing kinds of liqueur, soy sauce or edible oil is limited, because those kinds fluid are usually contained in a solid glass bottle, a plastic bottle or a tin can, which require a tilt of a container in order to discharge the fluids out.
- the structure also may cause irregularities in case a content of the container includes granulated solid material, such as dressing, as some granules may remain in the area between the outside surface of the inside plug and the inside surface of the nozzle portion resulting in obstructing an intimate contact, thus damaging airtightness.
- Patent Document 3 JP Patent Publication No. 2007-326581
- the container listed in Patent Document 3 is equipped with a beak nozzle functioning to check the reverse flow of fluid.
- the container shell keeps a degree of elasticity as it is made of laminated films. If a user were to put excessive pressure on the container shell, this may cause the liquid content to splash out from the discharge mouth, thus spotting the user's clothes or surroundings. Some remaining liquid can stay around the discharge mouth. A tumbled container may cause an undesired flow out of the content, resulting in loss of fluid and soiling the environment.
- This invention is made for the purpose of solving these problems of such conventional containers.
- An embodiment of this invention is characterized by the following description. It has a container inside that forms an internal space for storing fluids, a container outer shell that has an opening guiding the fluids from the internal space to outside, and a lid portion that covers the discharge opening of the container outer shell and shuts a discharge opening or mouth through which the fluids are discharged.
- the lid portion comprises a space connecting to a neck of the container, a plug contacting with the discharge mouth from the inside for closing the discharge mouth of the container leading to the outside, and a disk-form spring sustaining the plug.
- the spring helps the plug move toward the inside with the inner pressure of the container increased, and helps the plug move toward the outside to close the discharge mouth with the inner pressure of the container decreased.
- the discharge mouth is usually in a closed state with the plug under pressure from inside of the container.
- An addition of pressure on the container shell causes the plug to move toward inside, thus opening the discharge mouth.
- a release of pressure helps the plug return to the original position, resulting in closing the discharge mouth, which can prevent fluid contents from degenerating or deteriorating because it shuts out fresh air and checks a reverse flow of fluid contents.
- the container can be equipped with a stopper in the lid portion for regulating movements of the plug.
- the container can also be equipped with a manually operative lever in the lid portion, which makes either movement of the plug toward the inside or toward the outside.
- the discharge mouth can be configured cylinder-like or conical so that the discharge opening protrudes toward outside of the container.
- a container inside forms an internal space for storing fluids
- a container outer shell has a discharge mouth guiding fluids from the internal space of the container inside to the outside, and a lid that covers an opening of the container outer shell and shuts the discharge mouth through which fluid material is discharged.
- the lid portion has a discharge hole.
- a thin film forms a tubular portion or tube that is usually flattened with one end of the film connected to the discharge hole of the lid and the other end forms the discharge mouth.
- the container is characterized by the discharge mouth guiding fluid from the inside to the outside.
- the discharge mouth as put upright, is in a closed position as the tube remains flattened, and when a user tilts the container in order to discharge fluid content, the weight of fluid content forms pressure that causes the discharge mouth to open and the content to be discharged.
- the discharge mouth returns to its closed state with the tube again getting flattened.
- This closed state of the discharge mouth can prevent the fluid content from degrading or deteriorating due to an inflow of air and the halt of reversal flow of the fluid.
- the tube as made from a flexible thin film, can be flattened with granules remaining in the tube.
- the container can be equipped with an inner bag that has an internal space for storing fluids inside of the container.
- a space is formed between the inner bag and the inside of the container outer shell, and the space can be linked to outside air.
- the container can be equipped with an internal space for storing air, and the space can be linked to outside air.
- the container can be equipped with an absorbing material for absorbing residuals of fluids remaining around the discharge mouth.
- the container can be equipped with a pump mechanism in the lid portion or the container body that helps increase pressure inside of the container.
- the container can be equipped with the surface of the lid portion being coated with an oxygen-proof thin film that is made of plastic or metal in order to prevent oxygen from entering the inside of the container.
- the lid portion can comprise a space connecting to a neck of the container, a plug contacting with a discharge mouth from the inside for closing the discharge mouth of the container leading to the outside, and a disk-form spring sustaining the plug.
- the spring helps the plug move toward the inside with the inner pressure of the container increased, and helps the plug move toward the outside to close the mouth of the container with the inner pressure of the container decreased.
- the lid portion covers the opening of the container outer shell and shuts the discharge mouth through which fluid material is discharged.
- the lid portion has a discharge hole.
- a thin film that forms a tubular shape that is usually flattened with one end of the film connected to the discharge hole of the lid and the other end connecting to the discharge mouth.
- the discharge mouth guides fluid from the inside to the outside.
- it can be equipped with an inner bag for storing air.
- the plug when the pressure of the container is lowered, the plug returns to its original shape and closely fits to the discharge port, thus causing a closed state and preventing the new entry of outside air and the reverse flow of the liquid substance once discharged outside. Therefore, the deterioration of the substance inside of the container can be checked.
- the discharge mouth and surroundings can safely and easily be put into cleaning operations as the discharge mouth is in a closed state, making it possible to keep it clean.
- the pressure added by the content is quickly lowered and the outlet portion returns to its original shape.
- the relative inner surface is brought into close contact and the discharge mouth closes, thus making it possible to prevent the new entry of outside air and the reverse flow of the liquid substance once discharged outside. Therefore, the deterioration of the substance in the container can be prevented.
- the discharge mouth and its surroundings are cleaned after the content is taken out, the work can safely and easily be put into cleaning operations as the discharge mouth is in a closed state, making it possible to keep it clean.

- FIG. 3 is a view showing an opened state of the discharge mouth 7 of the liquid substance storage container.
- the liquid storage container shown in FIG. 1 is a tube-like container equipped with a tube-like container shell 6 and a lid portion.
- the container shell 6 is equipped with a flexible containing portion 6 b and an opening portion 6 a .
- the containing portion 6 b is formed into a bag having inner space closed to the inside.
- the inner space is filled with a liquid or a liquid substance such as a gel.
- the opening portion 6 a is provided in an end portion of the containing portion 6 b and is connected to the inner space formed by the containing portion.
- the lid body 5 is installed in a way to close the opening portion 6 a .
- matching screws are formed for joining.
- the lid body 5 is formed in a tube. At one end portion in the direction to take out the content, the inner lid 2 is installed and at the other end (the side of the opening portion 6 a ), a bottom plate 20 is provided, thus forming a space inside the lid body 5 .
- a circular or polygonal column form for the plug 3 is provided.
- the outside of a wavy spring portion 8 radially spreads from a specified position at the outer periphery of the plug 3 and is fixed to the inner wall of the lid body 5 .
- the inner lid 2 is provided with the discharge mouth 7 . Normally, a protruding portion of the plug 3 is in close contact with the inner lid 2 in the form to block the discharge mouth 7 from the inside.
- the protruding portion of the 3 can be moved in a direction away from the discharge mouth 7 owing to functions of the wavy spring portion 8 , thereby opening and closing the discharge mouth 7 .
- the internal space of the lid body 5 is separated into a first chamber 17 and a second chamber 18 by the wavy spring portion 8 of the plug 3 .
- the first chamber 17 is connected to the containing portion 6 b through an outflow hole 19 and the second chamber 18 is connected to outside air through an air port or hole 4 of the lid body 5 .
- the containing portion 6 b is pressurized to discharge a liquid substance as the content
- the content in the containing portion 6 a moves to the first chamber 17 through the outflow hole 19 .
- the wavy spring portion 8 is deformed and the portion in contact with the discharge mouth 7 of the plug 3 moves in a direction away from the discharge mouth 7 , thereby opening the discharge mouth 7 , and the content is discharged from the discharge mouth 7 .
- the plug 3 returns to its original form due to the elastic restoring force of the wavy spring portion 8 . Since the second chamber 18 is connected to outside air through the air hole 4 , the air pressure in the second chamber is always same as that of the outside air, and so it does not prevent the deforming/moving of the plug 3 .
- the content going outside through the discharge mouth 7 does not reverse and outside air does not flow into the discharge mouth 7 .
- the surface surrounding the discharge mouth 7 of the inner lid 2 and the surface at the end of the plug 3 continuously form one surface, and since there is no irregularity or clearance on the surfaces, the structure helps keep the area from being contaminated, and the area can be kept clean as cleaning is easily done.
- the container can be washed in water, and if the content is oily substance, the container can be washed with cleaning solution suitable for the content, and the cleaning solution or contaminant will not enter through the discharge mouth 7 .
- the surface of the inner lid 2 and the end surface of the plug 3 are formed to become one planar surface when the lid is in a closed state, it will be best suited for taking the content using a fingertip, a glass rod, a spoon, a chopsticks or a brush. It is also a good idea to form one concave surface in the surface of the inner lid 2 and the end surface of the plug 3 and check the color, odor or volume by temporarily accumulating the content there. It is also good to mark graduations on the surface of the inner lid 2 so that the volume can be easily measured when the content is to be discharged.
- the content is skin lotion or cream to be directly applied on the skin
- various shapes can be formed to meet purposes by, for example, forming one convex surface in the surface of the inner lid 2 and the end surface of the plug 3 so that the content can be easily applied directly to the skin.
- FIG. 4 is a figure to explain Embodiment 3.
- Embodiment 3 provides an inner bag 14 , a space 14 b between the container shell 6 and the inner bag 14 , and an air hole 12 of the container shell 6 .
- the inner bag 14 remains deformed for the same volume as that of the content discharged, but the outer shape of the container shell 6 returns to its original shape by taking in the outside air into the space 14 b through the air hole 12 by its restoring force.
- the containing portion 6 b restores its original shape even after the content is discharged, and the beauty of the container will not be lost until the content is used out. Since the containing portion 6 b always maintains same shape, the operation is easy when the content is taken out by manually grasping the container shell 6 .
- FIGS. 5 , 6 and 7 are drawings to explain Embodiment 4.
- the basic structure is same as that of each embodiment described above, but a stopper 11 is added in addition to the structure of each embodiment described above.
- FIG. 5 shows the state of the plug 3 fixed in close contact with the discharge mouth 7 in a normal state (when closed).
- FIG. 6 shows a state of the fixing of the plug 3 released by moving the stopper 11 .
- FIG. 7 shows the discharge mouth 7 opened after the pressure is applied to the containing portion 6 b when the plug 3 is released and the discharge mouth 7 of the plug 3 is moved in the direction of the central portion in contact with the discharge port of the plug 3 in a direction away from the discharge mouth 7 due to the pressure of the content.
- the moving can be assisted by moving the stopper 11 to its original position.
- the stopper 11 of a slide type, but the stopper shape and mechanism can be of any shape so long as the motion of the plug 3 is assisted or controlled with fingertips.
- the stopper 11 in FIGS. 5 and 6 assists the moving of the plug 3 only in the direction for close contact with the discharge mouth 7 , but it is possible to assist reciprocating movement. In such a case, however, it should be noted that the content will reverse if the discharge mouth 7 is opened when the pressure in the container is lower than the pressure outside the container.
- FIG. 8 is a drawing to explain Embodiment 5.
- the outer shape of the discharge mouth 7 of the inner lid 2 which was flat in the case of each embodiment described above ( FIGS. 1 to 7 ), is formed extruding tubular or drill-like toward the takeout direction of the content from the side of the lid body 5 .
- the shape is convenient when the content is directly transferred to a desired place from the discharge mouth 7 .
- an auxiliary device for delicate working for example, attaching a decorative shape such as waveform on the content surface when the content is discharged.
- Embodiment 6 the basic structure is same as that of each embodiment described above but a difference is that the lid body 5 is provided with a pump mechanism.
- FIGS. 9 , 10 and 11 are drawings to show the composition of Embodiment 6.
- a pump mechanism is installed between the inner lid 2 and the bottom plate 20 .
- the pump mechanism is equipped with the first chamber 17 , the second chamber 18 , a pressure portion formed of a pump elastic portion 21 and a pushbutton 22 , and a check valve 16 .
- the check valve 16 is installed in the outflow hole 19 and the pressure portion is provided on the side surface of the lid body 5 .
- the pressure portion consists of the pump elastic portion 21 of a wavy spring type extruding from the side of the lid body 5 , which can repeatedly deflect/deform, and the pushbutton 22 , thicker than the pump elastic portion 21 and provided at the end portion of the pump elastic portion 21 .
- the check valve 16 is normally closed, and when the pushbutton 22 is pressed with a finger, the pressure in the first chamber 17 of the lid increases. By this pressure, the portion in contact with the discharge mouth 7 of the plug 3 is moved in the direction to leave the discharge mouth 7 , and the discharge mouth 7 is opened, thus pushing out the content.
- the pushbutton 22 is released, the pushbutton 22 is returned to its original position by the elastic restoring force of the pump elastic portion 21 , the first chamber 17 becomes negative in pressure, the plug 3 returns to its original shape, the discharge mouth 17 closes, the check valve 16 opens, and the content in the container shell 6 is moved into the first chamber 17 .
- a balloon portion 15 consisting of an elastic body to connect to the first chamber 17 against the lid body 5 .
- the balloon portion 15 is crushed to discharge the content from the discharge mouth 7 , and by releasing the pressure to the balloon portion 15 , the content is moved into the first chamber 17 from the container shell 6 .
- the container may not be flexible.
- the container shell 6 can be made with hard glass or metal. It is also possible to set the discharge amount each time the balloon portion 15 is crushed and discharge the content while easily measuring the discharge amount by the number of crushing times of the balloon portion 15 . It is convenient for a seasoning or a pharmaceutical to be taken out by measuring the discharge amount when in use. It is also possible to install the balloon portion 15 with an air check valve 23 in the air hole 12 of the container as shown in FIG. 11 . It is possible to control the discharge amount of the content by controlling the air amount to flow into the space 14 b between the container and inner bag by means of the balloon portion 15 .
- FIG. 12 is a drawing to show the composition of Embodiment 7. As shown in FIG. 12 , a thin film 24 of plastic or metal with high oxygen barrier property is attached, or a thin film is formed by plating, evaporating or applying.
- the material of the container shell 6 conventionally a material of multilayered construction with high oxygen barrier property is used to prevent oxygen permeability, but for the lid portion, the opening of the container is closed by attaching an aluminum seal to it, thus preventing oxygen permeability before unsealing. For this reason, if the material of the lid portion is polyethylene with low oxygen barrier property, the oxygen preventive function is low even in the state where the lid closed after the aluminum seal is unsealed and removed.
- the oxygen permeability can be prevented by means of the thin film 24 with high oxygen barrier property for the inner lid 2 and the lid body 5 .
- the oxygen preventive function can be strengthened even when the lid portion is formed with a material such as polyethylene or polypropylene conventionally and normally used, which relatively easily allows the oxygen to pass.
- Embodiment 8 is explained below while referring to the drawings.
- the same symbols are used for explaining.

Abstract
A fluid storage container includes a container body provided with an interior space for storing a fluid and an opening for guiding the fluid from the interior space to the outside. A lid covers the opening of the container and is provided with a discharge opening for the fluid. The discharge opening is configured so that the discharge opening is normally in a closed state, sealed by a plug, but is set to an open state when extracting the fluid from the container body. Thus, outside air and impurities are prevented from entering the container, which prevents the degradation of the contents of the container and thereby drastically increases the lifespan of the contents.
Description
- This invention involves a container for preserving liquid or gelatinous material inside. It especially relates to structures of a lid equipped with a discharge mouth that guides fluid from the inside to the outside and to a container equipped with the lid.
- The conventional structure of a container for preserving liquid or gelatinous material fails to prevent air from flowing into the inside of the container, especially when the fluid content is discharged through the discharge mouth. This causes the content to become oxidized, and the remnant of the content remaining around the discharge mouth cannot be prevented from entering the inside of the container, resulting in degradation or deterioration of the content of the container.
- As for the structure of a container to prevent an inflow of air, there are container structures listed in Patent Document 1 (JP Patent No. 3492600) and Patent Document 2 (JP Utility Model Publication No. 58-021399). In either model, an inflow of air intends to be checked by a valve which can be opened or closed depending on a pressure level of the inside of the container. The valve can open with increased pressure inside of the container, for instance, when a user manually puts pressure on the container outer shell made of flexible material, and can close when he or she releases the pressure.
- The container structure listed in
Patent Document 1 comprises a tubular outer shell of a container that made of flexible material with a discharge mouth, an inside plug that shuts the discharge mouth with the central part protruding toward the outside, passages equipped with the inside plug that connect the inside of the container to the outside, and a nozzle portion surrounding part of the discharge mouth, made of elastic resin or rubber, and intimately contacted with the outside surface of the inside plug. - The addition of pressure to the container shell increases a level of the inside pressure of the container that results in the nozzle portion swelling as a result of its elasticity, making space between the inside plug and the nozzle portion that causes the contained fluid to discharge.
- A halt to giving pressure, owning to rebounding power produced by a deficit of pressure inside the container, helps the swelled nozzle portion recover to the original position getting intimately contacted with the surface of the inside plug. The structure referred to
Patent Document 1 works as such. - According to the first embodiment of the invention listed in
Patent Document 1, the elasticity of the nozzle portion material enables the discharge mouth to open and close. The characteristic of the invention depends only on the elasticity of the nozzle portion material. The elasticity alone is not sufficient to produce between the plug and the nozzle portion a space to help fluids be discharged from the container. The elasticity in turn prevents the nozzle portion from having sufficient intensity to secure airtightness. Airtightness could be incurred when an unintentional handling of the nozzle portion mistakenly triggers the nozzle part to deform or get disconnected. - According to the second embodiment of the invention listed in
Patent Document 1, the nozzle portion of the container has the V-curve area, which in practice makes it impossible to automatically return to the original position after making the discharge mouth open. - In addition, with the invention listed in
Patent Document 2, a lid portion is equipped with the neck portion of the container that closes the opening of the neck, comprising a cylinder with a discharge mouth in the center, and a plug equipped with a piston intimately contacted from inside of the cylinder. The plug and the piston remain raised up from below inside toward the discharge mouth. The addition of pressure to the container shell increases an internal pressure level of the container that results in the piston moving away from the mouth owning to the pressure inside of the container, triggering fluids to discharge with the plug detached from the discharge mouth. With the pressure inside of the container decreased, the cylinder returns to the original position, causing the plug to close the discharge mouth. The structure is complex and costly to produce, and there is a possibility that fluids may remain in a space between the cylinder and the piston, preventing a normal operation or causing irregularities. - Moreover, as the container listed either in
Patent Document 1 orPatent Document 2 is structured to require pressure to be added on the outer shell of the container in order to make contained fluid to discharge through the discharge mouth, its utility value as a container for storing kinds of liqueur, soy sauce or edible oil, is limited, because those kinds fluid are usually contained in a solid glass bottle, a plastic bottle or a tin can, which require a tilt of a container in order to discharge the fluids out. The structure also may cause irregularities in case a content of the container includes granulated solid material, such as dressing, as some granules may remain in the area between the outside surface of the inside plug and the inside surface of the nozzle portion resulting in obstructing an intimate contact, thus damaging airtightness. - The container listed in Patent Document 3 (JP Patent Publication No. 2007-326581) is equipped with a beak nozzle functioning to check the reverse flow of fluid. The container shell keeps a degree of elasticity as it is made of laminated films. If a user were to put excessive pressure on the container shell, this may cause the liquid content to splash out from the discharge mouth, thus spotting the user's clothes or surroundings. Some remaining liquid can stay around the discharge mouth. A tumbled container may cause an undesired flow out of the content, resulting in loss of fluid and soiling the environment.
- This invention is made for the purpose of solving these problems of such conventional containers.
- An embodiment of this invention is characterized by the following description. It has a container inside that forms an internal space for storing fluids, a container outer shell that has an opening guiding the fluids from the internal space to outside, and a lid portion that covers the discharge opening of the container outer shell and shuts a discharge opening or mouth through which the fluids are discharged.
- The lid portion comprises a space connecting to a neck of the container, a plug contacting with the discharge mouth from the inside for closing the discharge mouth of the container leading to the outside, and a disk-form spring sustaining the plug. The spring helps the plug move toward the inside with the inner pressure of the container increased, and helps the plug move toward the outside to close the discharge mouth with the inner pressure of the container decreased.
- According to this embodiment, the discharge mouth is usually in a closed state with the plug under pressure from inside of the container. An addition of pressure on the container shell causes the plug to move toward inside, thus opening the discharge mouth. A release of pressure helps the plug return to the original position, resulting in closing the discharge mouth, which can prevent fluid contents from degenerating or deteriorating because it shuts out fresh air and checks a reverse flow of fluid contents. In need of cleaning the discharge mouth, it is easy to clean as the discharge mouth is in a closed position.
- In this embodiment of this invention, the container can be equipped with a stopper in the lid portion for regulating movements of the plug.
- In an embodiment of this invention, the container can also be equipped with a manually operative lever in the lid portion, which makes either movement of the plug toward the inside or toward the outside.
- In an embodiment of this invention, the discharge mouth can be configured cylinder-like or conical so that the discharge opening protrudes toward outside of the container.
- To achieve the purposes above, in another embodiment of this invention, a container inside forms an internal space for storing fluids, a container outer shell has a discharge mouth guiding fluids from the internal space of the container inside to the outside, and a lid that covers an opening of the container outer shell and shuts the discharge mouth through which fluid material is discharged. The lid portion has a discharge hole. A thin film forms a tubular portion or tube that is usually flattened with one end of the film connected to the discharge hole of the lid and the other end forms the discharge mouth. The container is characterized by the discharge mouth guiding fluid from the inside to the outside.
- According to this embodiment above, the discharge mouth, as put upright, is in a closed position as the tube remains flattened, and when a user tilts the container in order to discharge fluid content, the weight of fluid content forms pressure that causes the discharge mouth to open and the content to be discharged. When the container is returned to the original upright state, losing the pressure of the fluid content, the discharge mouth returns to its closed state with the tube again getting flattened. This closed state of the discharge mouth can prevent the fluid content from degrading or deteriorating due to an inflow of air and the halt of reversal flow of the fluid. Even in case where the fluid content includes a granulated substance, the tube, as made from a flexible thin film, can be flattened with granules remaining in the tube.
- In need of cleaning the discharge mouth, it is easy to clean as the discharge mouth is in a closed position, so it contributes to sanitation.
- According to this embodiment, the container can be equipped with an inner bag that has an internal space for storing fluids inside of the container. A space is formed between the inner bag and the inside of the container outer shell, and the space can be linked to outside air.
- According to this embodiment, the container can be equipped with an internal space for storing air, and the space can be linked to outside air.
- In addition, according to this embodiment, the container can be equipped with an absorbing material for absorbing residuals of fluids remaining around the discharge mouth.
- According to this embodiment, the container can be equipped with a pump mechanism in the lid portion or the container body that helps increase pressure inside of the container.
- According to this embodiment, the container can be equipped with the surface of the lid portion being coated with an oxygen-proof thin film that is made of plastic or metal in order to prevent oxygen from entering the inside of the container.
- To achieve the purposes above, in another embodiment of this invention, the lid portion can comprise a space connecting to a neck of the container, a plug contacting with a discharge mouth from the inside for closing the discharge mouth of the container leading to the outside, and a disk-form spring sustaining the plug. The spring helps the plug move toward the inside with the inner pressure of the container increased, and helps the plug move toward the outside to close the mouth of the container with the inner pressure of the container decreased.
- To achieve the purposes above, in another embodiment of this invention, the lid portion covers the opening of the container outer shell and shuts the discharge mouth through which fluid material is discharged. The lid portion has a discharge hole. A thin film that forms a tubular shape that is usually flattened with one end of the film connected to the discharge hole of the lid and the other end connecting to the discharge mouth. The discharge mouth guides fluid from the inside to the outside. In the embodiment of the invention concerning the lid portion, it can be equipped with an inner bag for storing air.
- According to an embodiment of this invention, when the pressure of the container is lowered, the plug returns to its original shape and closely fits to the discharge port, thus causing a closed state and preventing the new entry of outside air and the reverse flow of the liquid substance once discharged outside. Therefore, the deterioration of the substance inside of the container can be checked. The discharge mouth and surroundings can safely and easily be put into cleaning operations as the discharge mouth is in a closed state, making it possible to keep it clean.
- According to another embodiment of this invention, with the container put to a stand state, the pressure added by the content is quickly lowered and the outlet portion returns to its original shape. The relative inner surface is brought into close contact and the discharge mouth closes, thus making it possible to prevent the new entry of outside air and the reverse flow of the liquid substance once discharged outside. Therefore, the deterioration of the substance in the container can be prevented. When the discharge mouth and its surroundings are cleaned after the content is taken out, the work can safely and easily be put into cleaning operations as the discharge mouth is in a closed state, making it possible to keep it clean.

FIG. 1 is a cross-sectional view of a liquid substance storage container related to this embodiment.FIG. 2A is the circular dotted line part excerpt fromFIG. 1 showing a state with an outer cap orlid 1 removed. These views show adischarge mouth 7 in a closed state with aplug 3 in close contact with thedischarge mouth 7.FIG. 2B is a plan view of aninner lid 2.FIG. 2C is a plan view of theplug 3.FIG. 2D is a plan view of alid body 5.FIG. 3 is a view showing an opened state of thedischarge mouth 7 of the liquid substance storage container. - The liquid storage container shown in
FIG. 1 is a tube-like container equipped with a tube-like container shell 6 and a lid portion. Thecontainer shell 6 is equipped with a flexible containingportion 6 b and anopening portion 6 a. The containingportion 6 b is formed into a bag having inner space closed to the inside. The inner space is filled with a liquid or a liquid substance such as a gel. - The
opening portion 6 a is provided in an end portion of the containingportion 6 b and is connected to the inner space formed by the containing portion. - To the
opening portion 6 a of thecontainer 6, thelid body 5 is installed in a way to close theopening portion 6 a. For theconnection 10 of thecontainer 6 and thelid body 5, matching screws are formed for joining. - For the lid portion, the
lid body 5 is formed in a tube. At one end portion in the direction to take out the content, theinner lid 2 is installed and at the other end (the side of theopening portion 6 a), abottom plate 20 is provided, thus forming a space inside thelid body 5. - Near the center of the
lid body 5, a circular or polygonal column form for theplug 3 is provided. For theplug 3, the outside of awavy spring portion 8 radially spreads from a specified position at the outer periphery of theplug 3 and is fixed to the inner wall of thelid body 5. - The
inner lid 2 is provided with thedischarge mouth 7. Normally, a protruding portion of theplug 3 is in close contact with theinner lid 2 in the form to block thedischarge mouth 7 from the inside. - The protruding portion of the 3 can be moved in a direction away from the
discharge mouth 7 owing to functions of thewavy spring portion 8, thereby opening and closing thedischarge mouth 7. - The internal space of the
lid body 5 is separated into afirst chamber 17 and asecond chamber 18 by thewavy spring portion 8 of theplug 3. Thefirst chamber 17 is connected to the containingportion 6 b through anoutflow hole 19 and thesecond chamber 18 is connected to outside air through an air port orhole 4 of thelid body 5. - If the containing
portion 6 b is pressurized to discharge a liquid substance as the content, the content in the containingportion 6 a moves to thefirst chamber 17 through theoutflow hole 19. By means of the pressure of the content filled in thefirst chamber 17, thewavy spring portion 8 is deformed and the portion in contact with thedischarge mouth 7 of theplug 3 moves in a direction away from thedischarge mouth 7, thereby opening thedischarge mouth 7, and the content is discharged from thedischarge mouth 7. - If the pressure is removed from the containing
portion 6 b, the interior of the containingportion 6 b and thefirst chamber 17 are made negative by the force of the containingportion 6 b to return to the original form. - The
plug 3 returns to its original form due to the elastic restoring force of thewavy spring portion 8. Since thesecond chamber 18 is connected to outside air through theair hole 4, the air pressure in the second chamber is always same as that of the outside air, and so it does not prevent the deforming/moving of theplug 3. - As shown by these figures, the content going outside through the
discharge mouth 7 does not reverse and outside air does not flow into thedischarge mouth 7. - When the
discharge mouth 7 and its surrounding are in need of cleaning, there is no concern about remaining content or contaminant entering through thedischarge mouth 7 as thedischarge mouth 7 is tightly closed. - When in a closed state, the surface surrounding the
discharge mouth 7 of theinner lid 2 and the surface at the end of theplug 3 continuously form one surface, and since there is no irregularity or clearance on the surfaces, the structure helps keep the area from being contaminated, and the area can be kept clean as cleaning is easily done. - If the content is a water-soluble substance such as toothpaste, the container can be washed in water, and if the content is oily substance, the container can be washed with cleaning solution suitable for the content, and the cleaning solution or contaminant will not enter through the
discharge mouth 7. - If the surface of the
inner lid 2 and the end surface of theplug 3 are formed to become one planar surface when the lid is in a closed state, it will be best suited for taking the content using a fingertip, a glass rod, a spoon, a chopsticks or a brush. It is also a good idea to form one concave surface in the surface of theinner lid 2 and the end surface of theplug 3 and check the color, odor or volume by temporarily accumulating the content there. It is also good to mark graduations on the surface of theinner lid 2 so that the volume can be easily measured when the content is to be discharged. - If the content is skin lotion or cream to be directly applied on the skin, various shapes can be formed to meet purposes by, for example, forming one convex surface in the surface of the
inner lid 2 and the end surface of theplug 3 so that the content can be easily applied directly to the skin. - With this embodiment, not only the wave form but also other optimum shapes are formed by making the
wavy spring portion 8 inEmbodiment 1 using a flexible and elastic material. In such a case, it is also possible to install at a desired place a spring of a desired shape such as spiral or leaf to assist the force to direct theplug 3 toward thedischarge mouth 7. -
FIG. 4 is a figure to explainEmbodiment 3. In addition toEmbodiment 1,Embodiment 3 provides aninner bag 14, aspace 14 b between thecontainer shell 6 and theinner bag 14, and anair hole 12 of thecontainer shell 6. - If the pressure of the
container shell 6 is removed after the content is discharged, theinner bag 14 remains deformed for the same volume as that of the content discharged, but the outer shape of thecontainer shell 6 returns to its original shape by taking in the outside air into thespace 14 b through theair hole 12 by its restoring force. - Since no outside air enters the
inner bag 14, contact between the content and outside air is prevented and the initial shape is maintained for the outer shape of thecontainer shell 6. - When the content is taken out, pressure is applied by blocking the
air hole 12 with a finger. It is also possible to adopt a check-valve structure for theair hole 12 in advance. With the container of this embodiment, the containingportion 6 b restores its original shape even after the content is discharged, and the beauty of the container will not be lost until the content is used out. Since the containingportion 6 b always maintains same shape, the operation is easy when the content is taken out by manually grasping thecontainer shell 6. -
FIGS. 5 , 6 and 7 are drawings to explainEmbodiment 4. The basic structure is same as that of each embodiment described above, but astopper 11 is added in addition to the structure of each embodiment described above.FIG. 5 shows the state of theplug 3 fixed in close contact with thedischarge mouth 7 in a normal state (when closed).FIG. 6 shows a state of the fixing of theplug 3 released by moving thestopper 11.FIG. 7 shows thedischarge mouth 7 opened after the pressure is applied to the containingportion 6 b when theplug 3 is released and thedischarge mouth 7 of theplug 3 is moved in the direction of the central portion in contact with the discharge port of theplug 3 in a direction away from thedischarge mouth 7 due to the pressure of the content. - In the state of
FIG. 6 , thedischarge mouth 7 is blocked in close contact by the elastic restoring force to work toward thedischarge mouth 7 of theplug 3 in a normal state, but in the state ofFIG. 5 , theplug 3 is fixed by thestopper 11, thus ensuring a closed state. This arrangement is effective when a user wants to completely close the container when in need of carrying it outside or when the content is not used for a long period of time. - When it is difficult to move the
plug 3 to the position for close contact with thedischarge mouth 7 using only the elastic restoring force of theplug 3 when the content has high viscosity, the moving can be assisted by moving thestopper 11 to its original position. This makes it possible to store liquid substance of high viscosity. These figures show thestopper 11 of a slide type, but the stopper shape and mechanism can be of any shape so long as the motion of theplug 3 is assisted or controlled with fingertips. For example, thestopper 11 inFIGS. 5 and 6 assists the moving of theplug 3 only in the direction for close contact with thedischarge mouth 7, but it is possible to assist reciprocating movement. In such a case, however, it should be noted that the content will reverse if thedischarge mouth 7 is opened when the pressure in the container is lower than the pressure outside the container. -
FIG. 8 is a drawing to explainEmbodiment 5. WithEmbodiment 5, the outer shape of thedischarge mouth 7 of theinner lid 2, which was flat in the case of each embodiment described above (FIGS. 1 to 7 ), is formed extruding tubular or drill-like toward the takeout direction of the content from the side of thelid body 5. - The shape is convenient when the content is directly transferred to a desired place from the
discharge mouth 7. At the end portion of thedischarge mouth 7, it is possible to separately attach an auxiliary device for delicate working, for example, attaching a decorative shape such as waveform on the content surface when the content is discharged. - In
Embodiment 6, the basic structure is same as that of each embodiment described above but a difference is that thelid body 5 is provided with a pump mechanism.FIGS. 9 , 10 and 11 are drawings to show the composition ofEmbodiment 6. - In the example shown in
FIG. 9 , a pump mechanism is installed between theinner lid 2 and thebottom plate 20. The pump mechanism is equipped with thefirst chamber 17, thesecond chamber 18, a pressure portion formed of a pumpelastic portion 21 and apushbutton 22, and acheck valve 16. - The
check valve 16 is installed in theoutflow hole 19 and the pressure portion is provided on the side surface of thelid body 5. The pressure portion consists of the pumpelastic portion 21 of a wavy spring type extruding from the side of thelid body 5, which can repeatedly deflect/deform, and thepushbutton 22, thicker than the pumpelastic portion 21 and provided at the end portion of the pumpelastic portion 21. - The
check valve 16 is normally closed, and when thepushbutton 22 is pressed with a finger, the pressure in thefirst chamber 17 of the lid increases. By this pressure, the portion in contact with thedischarge mouth 7 of theplug 3 is moved in the direction to leave thedischarge mouth 7, and thedischarge mouth 7 is opened, thus pushing out the content. - If the
pushbutton 22 is released, thepushbutton 22 is returned to its original position by the elastic restoring force of the pumpelastic portion 21, thefirst chamber 17 becomes negative in pressure, theplug 3 returns to its original shape, thedischarge mouth 17 closes, thecheck valve 16 opens, and the content in thecontainer shell 6 is moved into thefirst chamber 17. - In the above explanation, the installation of a pressure portion on the side surface of the
lid body 5 is illustrated. Instead of the installation of a pressure portion, it is also possible to form the entire side wall of thelid body 5 with an elastic body. In such a case, the pump action described above is demonstrated by pushing or releasing the lid itself. - As shown in
FIG. 10 , it is also possible to include aballoon portion 15 consisting of an elastic body to connect to thefirst chamber 17 against thelid body 5. In this case, theballoon portion 15 is crushed to discharge the content from thedischarge mouth 7, and by releasing the pressure to theballoon portion 15, the content is moved into thefirst chamber 17 from thecontainer shell 6. - As described above, with this embodiment, it is not necessary to deform the
container shell 6 by applying pressure to the container. For this reason, in the case of the container provided with theinner bag 14 ofEmbodiment 2, the container may not be flexible. For example, thecontainer shell 6 can be made with hard glass or metal. It is also possible to set the discharge amount each time theballoon portion 15 is crushed and discharge the content while easily measuring the discharge amount by the number of crushing times of theballoon portion 15. It is convenient for a seasoning or a pharmaceutical to be taken out by measuring the discharge amount when in use. It is also possible to install theballoon portion 15 with anair check valve 23 in theair hole 12 of the container as shown inFIG. 11 . It is possible to control the discharge amount of the content by controlling the air amount to flow into thespace 14 b between the container and inner bag by means of theballoon portion 15. -
FIG. 12 is a drawing to show the composition ofEmbodiment 7. As shown inFIG. 12 , athin film 24 of plastic or metal with high oxygen barrier property is attached, or a thin film is formed by plating, evaporating or applying. - As for the material of the
container shell 6, conventionally a material of multilayered construction with high oxygen barrier property is used to prevent oxygen permeability, but for the lid portion, the opening of the container is closed by attaching an aluminum seal to it, thus preventing oxygen permeability before unsealing. For this reason, if the material of the lid portion is polyethylene with low oxygen barrier property, the oxygen preventive function is low even in the state where the lid closed after the aluminum seal is unsealed and removed. - In
Embodiment 7, the oxygen permeability can be prevented by means of thethin film 24 with high oxygen barrier property for theinner lid 2 and thelid body 5. The oxygen preventive function can be strengthened even when the lid portion is formed with a material such as polyethylene or polypropylene conventionally and normally used, which relatively easily allows the oxygen to pass. -
Embodiment 8 is explained below while referring to the drawings. For the same composition as that of each embodiment described above, the same symbols are used for explaining. -
FIG. 13 is a cross-sectional view near theopening portion 6 a of thecontainer shell 6 of the liquid substance storagecontainer concerning Embodiment 8.FIG. 14 is a cross-sectional view showing a state of thedischarge mouth 26 with theouter cap 1 shown inFIG. 13 removed.FIG. 15 is a plan view of theinner lid 2 inFIG. 14 .FIG. 16A is a plan view of thedischarge portion 25,FIG. 16B is a cross-sectional view as seen from the side of thedischarge portion 25,FIG. 16C is a cross-sectional view as seen from the side when thedischarge mouth 26 is opened, andFIG. 16D is a cross-sectional view of thedischarge portion 25 taken along line X-X ofFIG. 16C . - The liquid substance storage container of
Embodiment 8 is a bottle-like container equipped with a lid portion formed of the outer cap orlid 1, theinner lid 2 and the lid body 5), thecontainer shell 6 formed of theopening portion 6 a and the containingportion 6 b, thedischarge portion 25, and theinner bag 14. Inside theinner bag 14, a closedinner bag space 14 a is formed and in theinner bag space 14 a, a liquid or a liquid substance such as gel is filled. Theopening portion 6 a is provided at one end portion in the content discharge direction of the containingportion 6 b and the other end portion is connected to theinner bag space 14 a formed by theinner bag 14. Theopening portion 6 a ofEmbodiment 8 is cylindrical and an external thread is formed on the outside diameter. - The lid portion is installed in the form of blocking the
opening portion 6 a against thecontainer shell 6 and has theinner lid 2 in the form of partitioning the outside in the direction opposite to theopening portion 6 a.Inner lid 2 is equipped with thedischarge mouth 7 and theair inflow port 13. Thedischarge mouth 7 is connected to theinner bag space 14 a of theinner bag 14 via theopening portion 6 a. Theinner bag space 14 b between theinner bag 14 and the container outer wall, that is, the clearance between theinner bag space 14 a and the outer wall of the containingportion 6 b, is connected to outside air via theair inflow port 13. For theconnection 10 of thelid body 5, an external thread is formed on the inside diameter and joined to theopening portion 6 a. - The
discharge portion 25 is formed cylindrical with a flexible thin sheet, and one end portion of it is connected to thedischarge mouth 7 and has thedischarge mouth 26 at the other end portion. The inside of thedischarge portion 25 is connected to theinner space 14 a of theinner bag 14 via thedischarge mouth 7 and theopening portion 6 a. When the container stands, the relative surface on the cylindrical side of the thin sheet of thedischarge portion 25 is in close contact and thedischarge mouth 26 is closed. - If the
outer cap 1 is removed and thecontainer shell 6 is inclined in the content discharge direction to take out the liquid substance of the content, thedischarge portion 25 is radially spread from the center depending on the pressure of the moving content, and thedischarge mouth 26 is opened and the content is extracted. Outside air of the same volume as the content taken out flows into theinner space 14 b through theair inflow port 13. If thecontainer shell 6 is returned to the standing position, the pressure in thedischarge portion 25 is lost and thedischarge portion 25 is returned to its original shape where the relative inside of thedischarge portion 25 is brought into close contact so that thedischarge mouth 26 is blocked. - As described above, the
discharge mouth 26 is opened or closed interlocking with the movement of the content as thecontainer shell 6 is inclined, allowing only the extraction of the content, thus demonstrating the checking functions to prevent outside air and contaminant from entering through thedischarge mouth 26. - Even when the content is a liquid substance including granular solids, the
discharge portion 25, formed with flexible thin sheet which can be flexibly deformed, can block in close contact with the granular solids intact. In this case, thedischarge portion 25 from thedischarge mouth 7 to thedischarge mouth 26 may be made longer to strengthen the closing performance. - The liquid substance contained in the
inner space 14 a of theinner bag 14 is isolated from the air contained in theinner space 14 b by means of theinner bag 14. - Inside the
outer cap 1, an absorber (or cushion) 28 formed with a flexible material having high liquid absorbing property is installed, and when theouter cap 1 is closed, the sealing power of thedischarge mouth 25 and thedischarge mouth 7 is reinforced by the push pressure of theabsorber 28. Additionally, the sealing power of thedischarge mouth 26 and thedischarge mouth 7 may be increased by restricting the movement of the air in theinner space 14 b (the space between theinner bag 14 and the container outer wall) and the content in theinner space 14 a (the space in the inner bag 14) by blocking theair inflow port 13. - It is also possible to install the
absorber 28 in a removable way so that it can be removed as required and installed again after cleaning. This makes it easy to always keep clean the surrounding of thedischarge mouth 26. -
FIG. 17A shows a pen-tip type for thedischarge portion 25 as seen from the top of thedischarge mouth 26. If thecontainer shell 6 is slightly inclined when a small amount of the content is extracted, thedischarge mouth 26 is slightly opened like a clearance and a small amount of the content is extracted through the end portion of the pen-tip type along the pen-tip type edge of thedischarge mouth 26. If the inclination of thecontainer shell 6 is increased, thedischarge mouth 26 is opened in an O form (O type) and a maximum amount is extracted. If the content is a liquid substance with high viscosity or low fluidity, however, it may be difficult to make fine control of the extracted amount or obtain the effect of the pen-tip type. -
FIG. 17B shows that thedischarge mouth 26 is closed by fusing before it is opened and the end is manually torn and opened from the broken line portion Y when opening. This makes it possible to secure the airtightness before opening and also show the opened or closed state. To obtain an accurate shape of the discharge mouth, the tear portion may be provided with a flaw or thin portion to induce the tearing. - It is also possible to form the surface of the portion to support the
discharge portion 25 of thelid body 5 in such a way that the height gradually increases in the direction ofdischarge mouth 26 from the side of thedischarge mouth 7 when thecontainer shell 6 is in a standing position so that the content in thedischarge portion 25 induces liquid drawing under its own weight when thecontainer shell 6 is returned to a stand position. -
FIG. 19 is a drawing to explainEmbodiment 13. The basic composition is same as that of each embodiment described above, the only difference being that theair inflow port 13 is provided with an airinflow port lid 29 to be manually opened or closed. This makes it possible to extract the content only when the airinflow port lid 29 is pushed and opened with a finger so that the content will not flow out even when it is mistakenly turned over when the finger is released. - The basic composition of
Embodiment 14 is same as that of each embodiment described above, the only difference being that thelid body 1 is provided with a mechanism to control the discharge amount of the content by adjusting the inflow amount of outside air. In an example shown inFIG. 20 , theair inflow port 13 of thelid body 5 is linked with theballoon portion 15 as a simple pump mechanism to allow the entry of air of a fixed amount each action. - This makes it possible to take out the content of almost same volume as the inflow air while easily measuring, by crushing the
balloon portion 15 optional times. Since the pump mechanism forces the movement of outside air, the container can be used even for content with high viscosity and low fluidity. -
FIG. 18 is a cross-sectional view of a liquid substance storage container used to explainEmbodiment 15. In thisEmbodiment 15, the role of the space to contain the liquid substance of the content and the inflow air is reversed from that ofEmbodiment 8. The liquid substance is contained in theinner space 14 b between theinner bag 14 and the outer wall of the containingportion 6 b, and the inflow outside air is contained in theinner space 14 a in theinner bag 14. - The lid portion is installed in the form of blocking the
opening portion 6 a against thecontainer shell 6 and has theinner lid 2 in the form of partitioning the outside in the direction opposite to theopening portion 6 a. Theinner lid 2 is equipped with thedischarge mouth 7 and theair inflow port 13. Thedischarge mouth 7 is connected to theinner space 14 b via theopening portion 6 a, and theinner space 14 a is connected to outside air via theair inflow port 13. For theconnection 10 of thelid body 5, an internal thread is formed on the inside diameter and joined with theopening portion 6 a. - When the
container shell 6 is standing, the relative surface of the cylindrical inside of the thin sheet of thedischarge portion 25 is in close contact and thedischarge mouth 26 is closed. If theouter cap 1 is removed and thecontainer shell 6 is inclined in the direction of pouring the content to discharge the liquid substance of the content, thedischarge portion 25 is radially spread from the center under the pressure of the weight of the moving content and the content is extracted. The outside air of a same volume as that of the content taken out flows into theinner space 14 a in theinner bag 14 through theair inflow port 13 and is contained. If thecontainer shell 6 is returned to the standing position, the pressure in thedischarge portion 25 is lost, thedischarge portion 25 returns to its original shape, the relative inner surface ofdischarge portion 25 is brought into close contact, and thedischarge mouth 26 is closed. - As described above, the
discharge mouth 26 opens or closes interlocking with the movement of the content as the container inclines, allowing only the extraction of the content, thus demonstrating the check function to prevent the entry of outside air and contaminant through thedischarge mouth 26. Even when the content is liquid substance including granular solids, thedischarge portion 25 can close in close contact with the granular solids intact because it is formed with a flexible thin sheet that can flexibly deform. In this case, thedischarge portion 25 from thedischarge mouth 7 to thedischarge mouth 26 may be made longer. - The liquid substance contained in the
inner space 14 b is isolated from the air contained in theinner space 14 a by means of theinner bag 14. - Comparing
Embodiment 15 andEmbodiment 8, their advantages are explained below. The advantage ofEmbodiment 15 is that the lid portion and theinner bag 14 can be shared if the shape of theconnection 10 is common even when the shape of the containingportion 6 b is somewhat different, by forming the capacity of theinner bag 14 larger than the volume of the content. It is, therefore, possible for a consumer to attach to an optional container, after opening, the lid portion and theinner bag 14 having aconnection 11 suitable for the shape of the opening of the container. It is also possible for a seller of wine, for example, to propose a combination of the lid portion and theinner bag 14 for existing wine of a conventional container and for the consumer to attach it to the container when opening.FIG. 21 is a drawing of the lid portion and theinner bag 14 forEmbodiment 15. In this case, the inner bag may be folded or wadded. - If the capacity of the
container shell 6 is large, the size of theinner bag 14 also becomes large, but in such a case, it is possible to install inside theinner bag 14 a small tube of desired length formed with soft porous material so that theinner bag 14 is smoothly enlarged by inflowing air.Embodiment 15 is suitable when it is desired to reduce the initial investment per product type for multiple products of the content in small quantities. - On the other hand,
Embodiment 8 is suitable for large production and advantageous in terms of quality control of the container and cost (unit price). If the container is to be disposed of after the product is consumed, it is not necessary to clean the interior of thecontainer shell 6 once theinner bag 14 is removed, and it is, therefore, advantageous in recycling. - In this specification, the shape of the
container shell 6 is explained using a tube and bottle as an example, but containers of a box type or of a bag type may also be used. - In this specification, the fitting method is shown as the method of attaching the
outer cap 1 to thelid body 5, but this is an example. A hinge type, screw-in type, etc., may also be adopted. - In this specification, the screw-in type is used for the
connection 10 of thelid body 5 and thecontainer shell 6, but fitting type or fixing connection by thermal fusing may also be adopted. - As the material of the lid portion, various materials such as synthetic resin, metal, and carbon fiber are selectively used in consideration of the characteristic of the liquid substance to be stored and the use form. It is also possible to make the content difficult to stick or remain on the outside of the
discharge mouth 7 or thedischarge mouth 26 by attaching or applying in advance a substance repellent to the content to be stored. - The scope of the invention is not limited to the embodiments illustrated but includes all embodiments that can achieve the effects equivalent to the purposes of this invention. Furthermore, the scope of the invention includes various desired combinations of particular characteristics of all the characteristics disclosed.
- This invention can be effectively and properly utilized as liquid containers to internally store fluid substances including liquid and gel.
