JP-A-10-291549

  When using a container with a spout as described above, in certain fields, it may be desired to prevent outside air or the like from entering the container when the contents are taken out through the spout. This is because the nature of the contents may change due to the reaction with the contents when the outside air enters.

  When a container with a spout as in the prior art is used, the closure body is removed, and after the contents are poured out as it is, the closure body is opened and the dispensing operation is performed even if the closure body is attached again. In addition, outside air inevitably enters the housing section.

  The present invention has been made paying attention to the above-mentioned problems, and can be mounted on various types of containers with a spout that can be resealed by preventing outside air from entering when the contents are poured out. An object is to provide a simple plug.

  In order to achieve the above-described object, the present invention provides a storage body that forms a storage portion for storing contents by stacking sheet-like members and welding the surroundings, and a content attached to the storage body. A spouted container having a spout that allows the contents to be taken out, the spout comprising a spout part for pouring the contents to the outside, and an attaching part attached to the containing body, A holder having elasticity is supported in the spout portion, and a split plug comprising a pair of plug body portions that are in face-to-face contact with each other is fitted in the holder, and the split plug is formed of the contents. The plug body portions are pushed and expanded so as to be separated from each other by a pressing force, and the content extraction channel is secured, and the elastic restoring force of the holder is pressed against each other to close the extraction channel. Features.

  According to the above-described structure, the split plugs inserted into the holder are in a state where the plug parts are in pressure contact with each other. And, for example, when a pressing force due to the contents is generated against the split plug, for example, by applying an external pressure to the housing main body, the plug body portions that are in contact with each other come to be spread, Thus, a pouring channel is secured and the contents can be poured out from the pouring port. On the other hand, when the external pressure with respect to the housing body is released, the plug bodies can be brought into pressure contact with each other by the elastic restoring force of the holder, and the pouring channel is sealed again. For this reason, when taking out the contents via the spout, gas, liquid, or the like does not flow into the housing body from the outside, and a situation in which the properties of the contents change can be prevented.

  In the configuration described above, each plug body portion forming the split plug has a recessed pressure receiving portion that receives pressure in the housing body, and a pressure contact surface that is pressed against the opposite plug body portion, on opposite sides. It is preferable that the discharge flow path be secured by the pressing force of the contents acting on the pressure receiving portion and the pressure contact surfaces being separated from each other.

  In such a configuration, for example, when external pressure is applied to the housing main body and a pressing force is applied by the contents, the plug body portions can be effectively separated from each other, and the dispensing flow path of the split plug is opened. The plug responsiveness can be improved, and the sealing responsiveness of the split plug when the external pressure is removed can be increased as well.

  In the above-described configuration, it is preferable to further include guide means for guiding the contents in the housing main body to the pressure receiving portion.

  In such a configuration, the content is surely guided to the pressure receiving portion by the guide means, so that the split plug can be opened efficiently and the content can be poured out without waste.

  In order to achieve the above-mentioned object, the present invention provides a plug body that is detachably attached to a spout portion of a storage container that stores a predetermined content, and has a communication hole through which the content communicates. . An elastic holder is supported in the communication hole of the plug body, and a split plug comprising a pair of plug body portions that are in face-to-face contact with each other is fitted in the holder, Is secured by the pressing force of the contents so that the plug parts are spaced apart from each other, thereby securing a pouring channel for the contents, and pressing the pouring parts together by elastic restoring force of the holder The flow path is closed.

  According to such a stopper, the structure having the above-described features can be freely applied to any existing container.

  Moreover, if the pouring flow path can be secured between the holder and the inner surface of the holder by utilizing the elastic deformation of the holder itself, it is not necessary to insert the stopper plug structure. Moreover, even if the holder itself is a structure which does not elastically deform, the structure in which the plug part inserted by the inside elastically deforms may be sufficient. Or the structure which inserts and inserts into the spout part the elastic stopper structure which deform | transforms elastically, without providing a holder may be sufficient.

  According to the present invention, it is possible to obtain a spout-equipped container and a plug that can be re-sealed by preventing outside air from entering when the contents are poured out.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 show a first embodiment of a container with a spout, FIG. 1 is a schematic perspective view showing the main structure of the container with a spout, and FIG. FIG. 2B is a view of the spout spout portion of the container with spout 1 as viewed from above, FIG. 2B is a view of the spout spout portion of the spout as viewed from below, and FIG. 3 is the accommodation with spout of FIG. Fig. 4 is a schematic side view showing the main structure of the body, Fig. 4 is a diagram showing a split plug structure that is inserted into the spouted container, (a) is a front view of the plug body portion of the split plug, and (b) FIG. 5C is a plan view of the plug body, FIG. 5C is a side view of the plug body, and FIG. 5 is a perspective view of the split plug.

  FIG. 1 shows a substantially upper half of the spout-equipped container 1 and shows a state in which the spout 5 is attached. The housing body 1a of the spouted housing 1 is formed by stacking sheet-like members 8a and 8b made of a relatively flexible material such as synthetic resin and welding (thermal welding) around them. The The welded portion is indicated by the hatched portion 3, and the other portions are formed in a bag shape to form, for example, a storage portion S in which fluid content is stored. Here, about the accommodating main body 1a, it does not specifically limit about the whole shape, a magnitude | size, a welding area | region, etc., Various things are contained. For example, the overall shape of the housing main body 1a includes a so-called self-contained container that has a bottom portion and can stand upright, or a so-called trigonal body in which the peripheral regions of the two sheet-like members 8a and 8b are welded. It is.

  And when the sheet-like members 8a and 8b are welded, a spout 5 that allows the contents to be taken out is welded to the upper end portion thereof. The spout 5 is integrally formed in advance with a synthetic resin or the like, and is attached by being interposed between the upper ends of the two sheet-like members 8a and 8b. The spout 5 has a cylindrical spout portion 6 for projecting the contents from the housing body 1 to pour out the contents, and a cross-section ship shape (circular shape) attached to each sheet-like member of the housing body 1. And an attachment portion 7 formed on the surface.

  The sheet-like members 8a and 8b are flexible synthetic resin sheets (plastic films) as described above. For example, the sheet-like members 8a and 8b are made of polyethylene or polypropylene so as to be easily welded. Further, it is preferable that the surface side is constituted by a so-called composite layer in which nylon, aluminum foil, or the like is laminated so as to enhance the barrier property (gas barrier property and light shielding property) to the contents.

  The spout portion 6 is provided with a closing member (not shown) such as a screw-type cap or a pull-type cap.

  In the spout 5 described above, an elastic holder 9 is supported in the spout portion 6 (a communicating hole portion communicating with the accommodating portion S). The holder 9 is configured to fit and hold a later-described split plug, and is configured to be elastically deformable in the opening direction of the split plug. Specifically, the holder 9 of the present embodiment is configured by a cylindrical elastic thin film (for example, having a thickness of about 0.3 mm) formed in a substantially rectangular cross section. An insertion opening 9a (see FIG. 2) is provided on the side. The insertion opening 9a has a width of about 2 mm, for example. The cylindrical holder 9 is fixed to and supported by the inner surface of the spout portion 6 by supporting film pieces 9b and 9b that are positioned on both sides of the insertion opening 9a and extend along the spout portion 6. Yes.

  According to the holder structure as described above, the cylindrical part is easily bent by the thickness and the supporting film pieces 9b, 9b that support both ends, and can be held so that the inserted plug is opened. It becomes. Note that the size, shape, thickness, and the like of the holder can be appropriately changed depending on the type of contents, the size of the container, and the like.

  Further, the split plug 20 is inserted into the holder 9 through the opening 6 a and the insertion opening 9 a of the spout portion 6. As shown in FIGS. 4 and 5, the split plug 20 is composed of a pair of plug body portions 22 and 24 that are in face-to-face contact with each other.

  Each plug part 22, 24 is integrally formed of, for example, resin, and is inserted into the above-described holder 9 while being in contact with each other. The plug parts 22 and 24 are bent so that they are separated from each other by the pressing force of the contents when an external force is applied to the housing main body 1a, for example, so that the boundary portions that are in contact with each other are separated from each other. It has a structure in which the discharge channel is secured by being spread. That is, the split plug 20 is configured such that the contents can be poured out from the boundary portion 29 (see FIG. 5) where the plug body portions 22 and 24 are in contact.

  In the present embodiment, when an external force is applied to the housing main body 1a, each plug body portion 22 and 24 applies a pressure in the housing portion S to the sides facing each other so that a pouring channel is easily secured. It has concave pressure receiving portions 22b, 24b to be received and pressure contact surfaces 22c, 24c pressed against the opposing plug body portions 24, 22 (see FIG. 4). Moreover, each plug part 22 and 24 has crimping | compression-bonding surfaces 22a and 24a crimped | bonded to the inner surface of the holder 9 on the opposite side to the mutually opposing side.

  The plug parts 22 and 24 are in a combined state in which the pressure receiving parts 22b and 24b are opposed to each other and the pressure contact surfaces 22c and 24c are in contact with each other at a predetermined position in the holder 9. 24a is mounted by being inserted into the inner surface of the holder 9. At this time, the split plug 20 is formed with an opening 20a (see FIG. 5) facing the inside of the housing body 1a by the pressure receiving portions 22b and 24b.

  In the configuration described above, the plug parts 22 and 24 are inserted into the holder 9 in a state of being in contact with each other to form the split plug 20, so that, for example, the plug parts 22 and 24 are positioned for positioning. The flange 27 may be formed. The flange 27 functions to position and support the split plug 20 with respect to the holder 9 by contacting the upper end edge of the holder 9.

  Moreover, in this embodiment, the guide means 13 for guiding the contents in the housing main body 1a to the pressure receiving portions 22b and 24b of the plug bodies 22 and 24 is provided in the spout portion 6 of the spout 5. ing. This guide means 13 can be configured, for example, as a dome-shaped body that is provided integrally with the spout portion 6 of the spout 5 and whose inner cavities narrow toward the pressure receiving portions 22b, 24b.

  In the container 1 with a spout configured as described above, first, when external pressure is applied to the storage main body 1a by, for example, pinching the storage main body 1a by hand, the contents are spouted along the spout 5 side. The plug body portions 22 and 24 are pushed away from each other by the pressing force at that time, and a pouring flow path is secured in a portion in contact with each other (the split plug 20 is opened). To do). Specifically, the pressing force of the contents accompanying the external pressure (pressure in the housing main body 1a) is guided so as to be gradually narrowed through the guide means (dome-shaped body) 13, and the opening is opened in a state where the pressing force is increased. It acts on the recessed pressure receiving portions 22b and 24b of the plug body portions 22 and 24 through the portion 20a. Thereby, the plug body parts 22 and 24 can bend in a direction in which the plug parts 22 and 24 are expanded against each other against the elastic force of the holder 9, and the pressure contact surfaces 22 c and 24 c are separated from each other to secure the dispensing flow path.

  Note that the amount (outflow amount) of the content at this time can be adjusted by the elastic force of the holder 9 (the thickness of the holder portion, the structure of the support film pieces 9b, 9b, etc.). Alternatively, it can be adjusted by controlling the internal pressure (clamping pressure) in the housing main body 1a. Thus, when the split plug 20 is opened, the contents in the housing body 1a can flow out from the opening 6a of the spout portion 6 through the pour channel between the press contact surfaces 22c and 24c.

  On the other hand, when the external pressure applied to the housing main body 1a is released, the pressing force acting on the pressure receiving portions 22b and 24b disappears. Therefore, the plug body portions 22 and 24 are pressed against the pressure contact surfaces 22c and 22c by the elastic restoring force of the holder 9. 24c presses again, and the split plug 20 is sealed. In this way, by releasing the external pressure, the pressure contact surfaces 22c and 24c come into contact again with the elastic force of the holder 9, so that the outside air does not enter the housing portion. That is, the content flows out by applying external pressure to the housing body 1a, but at this time, the outside air does not enter the housing portion, and the discharge flow path is immediately closed by releasing the external pressure. Therefore, the contents and the outside air do not react.

  As described above, according to the spout-equipped container 1 of the present embodiment, the split plug 20 including the pair of plug body portions 22 and 24 is inserted into the holder 9, for example, by the pressing force of the contents accompanying the external pressure. Since the split plugs 20 are opened by expanding the plug parts 22 and 24 in an interview state, the plugs can be opened when the contents are poured out with a simple structure. Further, in the configuration of the present embodiment, the split plug 20 is closed due to a decrease in the internal pressure (removal of the external pressure) in the housing main body 1a, so that outside air does not enter the housing portion, and the housing is stored after opening. Even if the body 1 falls, it is possible to prevent the contents from flowing out.

  Furthermore, in this embodiment, each plug body part 22 and 24 which comprises the split plug 20 is the plug part which opposes the pressure-receiving part 22b and 24b of a concave shape which receives the pressure in the accommodating main body 1a on the mutually opposing side. The split plug 20 is opened when the pressure of the contents accompanying the external pressure acts on the pressure receiving portions 22b and 24b to separate the pressure contact surfaces 22c and 24c from each other. It is like that. For this reason, since the pressing force of the content accompanying external pressure can be efficiently and effectively converted into the action force that separates the plug body portions 22 and 24, the opening response of the split plug 20 can be improved. Furthermore, the closing response of the split plug 20 can be improved in the same manner.

  FIG. 6 shows an embodiment of a plug according to the present invention. In this embodiment, the spout structure in the above-described embodiment can be detachably attached to any existing storage container as an independent plug body 50. Specifically, the stopper 50 of the present embodiment is detachably attached to the spout 40a of the bottle-shaped storage container 40 that stores predetermined contents by screwing or press-fitting, It has the same internal structure as the spout 5 described above (the dome-shaped guide means 13 may or may not be provided).

  The plug body 50 supports the holder 9 having elasticity in the communication hole 50a as in the above-described embodiment, and a pair of plug body portions 22 and 24 that are in pressure contact with each other in the holder 9. A split plug 20 made of is inserted. In this case, the split plug 20 is configured such that the plug body portions 22 and 24 are pushed apart so as to be separated from each other by a pressing force by the contents, such as tilting the container 40, thereby pouring out the contents. A flow path is secured. Further, as described above, the outlet flow path is closed by being pressed against each other by the elastic restoring force of the holder 9. Note that a closure cap 60 is attached to the plug body 50 by screwing or the like.

  According to such a stopper 50, the structure having the above-described characteristics can be freely applied to any existing container 40. That is, it is possible to easily attach a stopper having a structure that does not allow air to flow into the contents of various containers such as PET bottles.

  The above-described split plug 20 can be implemented in various forms. Hereinafter, modifications of the split plug will be described. In addition, in the stoppers described below, the same reference numerals are assigned to the same parts as those of the stoppers described above.

  FIG. 7 shows a first modification of the split plug 20. In this modification, the plug body portions 22 and 24 are partially thinned so that the plug body portions 22 and 24 can be easily bent and the amount of outflow through the pouring channel can be increased. Yes. Specifically, grooves 22e and 24e are formed along the vertical direction at the center of the outer surface of each plug body 22 and 24, so that each plug body section 22 and 24 can be easily bent in a direction away from each other. Thus, it is possible to expand the pouring channel. According to such a configuration, the contents can be poured out without applying such a large pressing force to the housing main body 1a. Of course, the thinned and thickened portion can be appropriately deformed, and depending on the formation position, the contents can be poured out simply by tilting the housing body 1a. . In addition, even if each plug body part 22 and 24 becomes easy to bend, after pouring out the contents, since it is again interviewed by the elastic restoring force of the holder 9, the contents can be resealed. .

  Moreover, as shown in FIG. 7, it is preferable to form the recesses 22f and 24f that can hold the contents on the outlet side of the plug body portions 22 and 24 that constitute the split plug 20.

  Such recesses 22f, 24f can hold the contents in the portions when the contents are poured out and then the receiving body 1a is brought into its original state. In this way, by forming a recess that holds the contents, it is possible to reliably prevent the outside air or the like from flowing into the housing portion. That is, even when the container is in a dry state, the contents are held in the region that comes into contact with the outside air, so that the inflow of outside air or the like can be reliably suppressed.

  FIG. 8 shows a second modification of the split plug 20. The plug body portions 22 and 24 constituting the split plug 20 of the present modified example have a substantially pentagonal shape in a side view, and are opposite to the recessed pressure receiving portions 22b and 24b that receive the pressure inside the housing body 1a. The protrusions 22h and 24h are formed on the surface.

  Also, the pressure contact surfaces 22c, 24c (only one of 24c is shown) of the plug body portions 22, 24 that are in contact with each other are spaced from the pressure receiving portions 22b, 24b by a predetermined distance (this interval is a region where each plug body is in pressure contact). In this way, grooves 22g and 24g (only one of 24g is shown) are formed in the same shape. The grooves 22g and 24g serve as a flow path through which the contents flow when the plug parts 22 and 24 are in contact with each other, and are formed up to the regions of the protruding parts 22h and 24h. It is in the state opened to the end surface.

  In this case, the grooves 22g and 24g receive a pressure in the housing main body 1a, and a large flow rate is secured when the split plug 20 is opened by the pressure contact surfaces 22c and 24c being separated from each other via the pressure receiving portions 22b and 24b. In such a manner, it is formed so as to extend in the width direction, and is formed so as to extend to the projecting portions 22h and 24h at the central portion thereof. The protrusions 22h and 24h may be positioned so as to protrude outside the spout 5, for example.

  According to the split plug 20 having the above-described configuration, when external pressure is applied to the storage portion S of the storage body 1a with the protruding portions 22h, 24h of the plug bodies 22, 24 exposed to the outside, the pressure receiving portions 22b, The plug bodies 22 and 24 bend in a direction in which the plug bodies 22 and 24 expand through the 24b, so that the pressure contact surfaces 22c and 24c are separated from each other and the contents can flow.

  Then, the contents that have passed through the expanded pressure contact surfaces 22c and 24c flow along the grooves 22g and 24g, and can be poured out from the openings at the ends. In this case, since the groove | channel used as a flow path is formed in the press-contact surfaces 22c and 24c, it becomes possible to pour out the content, without applying so much pressing force. Moreover, in this structure, since the protrusion parts 22h and 24h will be in the state exposed from the spout 5, the liquid running out after pouring the contents will become favorable.

  In the above-described embodiment, the configuration of the split plug 20 (the shape of the pressure receiving portion, the shape of the thin-walled portion, the shape of the groove, etc.) can be appropriately modified according to the desired outflow amount, the viscosity of the contents, and the like. Is possible. Specifically, for example, grooves 22g and 24g having a shape as shown in FIGS. 9A and 9B may be formed.

  Moreover, about the above-mentioned holder 9, it is possible to deform | transform suitably according to the structure of a stopper plug, About the support method with respect to the cross-sectional shape, thickness, and a spout part, it is possible to deform | transform suitably. Further, the guide means 13 may be configured so that the contents can be guided with respect to the split plug, and may be configured simply by a flat surface without being formed in a dome shape.

  10 and 11 show a second embodiment of the spouted container, FIG. 10 is a schematic perspective view showing the main structure of the spouted container, and FIG. 11 shows the spouted container of FIG. FIG. 2 is a diagram showing a configuration of a plug part (outflow control part) installed in the holder. Note that in the embodiments described below, the same reference numerals are given to the same configurations as those in the above-described embodiments, and detailed description thereof is omitted.

  In the present embodiment, a cylindrical holder 9A having elasticity is supported in the spout portion 6 of the spout 5A (a communicating hole portion communicating with the accommodating portion S). A plug portion (outflow control portion) 70 that is in close contact with the inner peripheral surface of the holder 9A is fitted and inserted into the holder 9A in a state where it is prevented from coming off. In this case, as shown in FIG. 11, the plug portion 70 is configured as a substantially cylindrical solid body, and comes into close contact with the inner peripheral surface of the holder 9 </ b> A, from the accommodating portion side toward the close contact portion 70 a. An inclined surface 70b that gradually increases in diameter and an inclined surface 70c that gradually decreases in diameter toward the upper side (opening 6a side) of the contact portion 70a are formed.

  The plug part 70 described above is fitted from the lower side of the holder 9A, and is attached to the inner surface of the communication hole of the spout part 6 of the spout 5A at the lower end thereof so that the plug part 70 does not come out to the accommodating part side. A disc-shaped stopper 75 is fixed. Further, the stopper 75 is formed with a passage hole 75a (the number of formation is not limited) for allowing the contents to pass therethrough.

  When the plug portion 70 is pressed into the contents and flows into the contact portion through the passage hole 75a of the stopper 75, the holder portion 9A is positioned between the contact portion 70a and the inner surface of the holder 9A. Bends to function so that the contact portion 70a is separated. Thereby, the pouring flow path of the contents is secured as in the above-described embodiment. Further, when the pressing force of the contents disappears, the close contact portion 70a comes into close contact with the inner surface of the holder 9A by the elastic restoring force of the holder 9A, and the pouring channel is closed.

  According to such a configuration, the plug portion 70 can be easily assembled to the holder 9A.

  12 and 13 show a third embodiment of the spouted container, FIG. 12 is a schematic perspective view showing the main structure of the spouted container, and FIG. 13 shows the spouted container of FIG. FIG. 2 is a diagram showing a configuration of a plug portion installed in the holder.

  In the present embodiment, similarly to the second embodiment, the cylindrical holder 9A is supported in the spout portion 6 of the spout 5B (the communicating hole portion communicating with the housing portion S). A substantially cylindrical plug portion (outflow control portion) 80 that is in close contact with the inner peripheral surface of the holder 9A is fitted and inserted into the holder 9A in a state where it is prevented from coming off. In this case, the plug portion 80 is formed in a hollow shape by an elastically deformable material (for example, rubber) as shown in FIG. 13, and is opened in any portion that is in close contact with the inner peripheral surface of the holder 9A. 80a is formed.

  The plug portion 80 described above has substantially the same diameter as the holder 9A, and can be fitted from below the holder. In this case, since the plug portion 80 is formed of an elastically deformable material, the holder 9A can be formed to be somewhat thick. When the plug portion 80 is press-fitted into the holder, the plug portion 80 The elastic force of 80 prevents it from coming off. Therefore, there is no need to provide a stopper as in the second embodiment, and the assembling work can be simplified.

  When the plug portion 80 is pressed against the contents and the contents flow into the plug portion 80, the plug portion 80 is bent between the outer peripheral surface of the plug portion 80 and the inner surface of the holder 9A. It functions so that both are separated. Thereby, like the above-mentioned embodiment, the pouring channel for contents is secured through the opening 80a. Further, when the pressing force of the contents disappears, the outer peripheral surface of the plug portion 80 comes into close contact with the inner surface of the holder 9A by the elastic restoring force of the plug portion 80, and the pouring channel is closed.

  According to such a configuration, the plug portion 80 can be more easily assembled to the holder 9A. In addition, since the holder 9A may be configured not to be elastically deformed, the holder 9A may be thick, and the holder 9A may be formed on the inner surface of the spout portion 6 without forming the support film pieces 9b and 9b as in the above-described embodiment.

A split plug 120 is inserted and configured. In this case, both plug parts 122 and 124 are integrally formed of an elastically deformable material such as rubber, and are inserted into the spout part 6 in a state of being in contact with each other.

  As in the first embodiment described above, the plug parts 122 and 124 are elastically deformed so that, for example, an external force is applied to the housing body 1a so that they are separated from each other by the pressing force of the contents. Thus, as in the above-described embodiment, the boundary portions that are in contact with each other are pushed apart so as to be separated from each other, and the extraction flow path (the regions 150 indicated by hatching in FIG. 19 become pressure contact surfaces that face each other. It has a structure that ensures a discharge flow path. That is, the split plug 120 is capable of pouring the contents from the boundary portion 129 where the plug body portions 122 and 124 are in contact, and is pressed against each other by the elastic restoring force of each plug body portion 122 and 124. The pouring channel is closed to prevent air from entering the inside.

  In addition, the above-mentioned boundary part 129 has raised the joining area | region of the upper surface of each plug part 122,124 so that it may become a substantially triangular shape (a raised part is shown by 122a, 124a), and a boundary part is on the top part.

In this case, it is preferable that recessed pressure receiving portions 122b and 124b for receiving the pressure in the accommodating portion S are formed on opposite sides. Thereby, the plug parts 122 and 124 are press-fitted into the spout part 6 in a combined state in which the pressure receiving parts 122b and 124b are opposed to each other and the pressure contact surfaces 150 are in contact with each other.

  Further, in the configuration as described above, the regions of the pressure contact surface 150 are easily elastically deformed and separated from each plug body portion 122, 124 so that each plug body portion 122, 124 is easily elastically deformed. It is preferable to form a thin-walled portion having a reduced thickness. In the present embodiment, such a thin-walled portion is configured by forming recesses 122A and 124A on each upper surface. That is, by forming such recesses 122A and 124A, the region of the pressure contact surface 150 is easily elastically deformed, and the pouring channel is easily opened and closed.

  Further, such a spout structure can be applied to an independent plug structure as in the above-described embodiment, and can also be applied to a storage container as shown in FIGS. 6 and 14.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the configuration of the split plugs 20 and 120 (the shape of the pressure receiving portion, the shape of the thin wall portion, the shape of the groove, etc.) and the configuration of the plug portions 70 and 80 (shape, material, insertion method to the holder, etc.) are desired. Depending on the amount of spillage and the viscosity of the contents, it can be appropriately modified.

  Moreover, about the above-mentioned holders 9 and 9A, it is possible to deform | transform suitably according to the structure of the split plug and plug part inserted inside, About the support method with respect to the cross-sectional shape, thickness, and the spout part It can be modified as appropriate.
