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.

  In the case of a spout having a conventional closed body, in use, after removing the closed body and pouring the contents as it is, even if the closed body is attached again, the closed body is opened and the dispensing operation is performed. In the meantime, outside air will inevitably enter the housing section.

  The present invention has been made paying attention to the above-described problems, and it is an object of the present invention to provide a spout-equipped container and a plug that can be resealed by preventing outside air from entering when contents are poured out. And

In order to achieve the above-described object, the present invention provides an accommodation main body that forms an accommodation portion for accommodating contents by stacking sheet-like members and welding the periphery thereof, and the contents attached to the accommodation main body. A spout-equipped container having a spout that enables removal of an object, wherein the spout is a spout for pouring out the contents to the outside, and an attachment part attached to the housing body; the watch is disposed on the inner side of the outlet portion, anda hollow flow path wall forming the note overhead stream passage for note to out the contents to the outside, the inside of the channel wall, A plug body having an outer surface pressed against the inner surface of the flow path wall is disposed, and the flow path wall and / or the plug body is formed of a material that is easily elastically deformed in the radial direction , The flow path wall and the plug part are separated by the accompanying pressing force of the contents. The Note overhead stream path by being spread is secured, the outer surface of the plug body portion and the inner surface of the flow path wall by the restoring force of the flow channel wall and / or the plug part due to the release of the external pressure is pressed And the said extraction flow path is closed, It is characterized by the above-mentioned.

  According to the above-described configuration, the inner surface of the flow channel wall forming the extraction flow channel for communicating the housing portion to the outside is changed from the normal closed state in which the inner surface of the flow passage wall is in pressure contact with the outer surface of the plug body portion to the external pressure on the housing body. As the flow path wall is pushed away from the plug body by the pressing force of the accompanying contents, an extraction flow path is secured between the inner surface of the flow path wall and the outer surface of the plug body, and the spout The contents can be dispensed from the department. On the other hand, when the external pressure on the housing body is released, the inner surface of the flow channel wall and the outer surface of the plug member are pressed against each other by the restoring force of the flow channel wall and / or the plug member, and the dispensing flow channel is sealed. (The inner portion of the flow path wall and the outer surface of the plug portion are in close contact with each other to close the housing portion). Therefore, when taking out the contents via the spout, it is possible to prevent a gas or liquid from flowing into the housing body from the outside, and to prevent a situation in which the properties of the contents are changed. In addition, since the outer surface of the plug body can be pressed against the inner surface of the flow path wall by fitting the plug body into the flow path wall, spout can be easily molded, and the plug body Assembly work is also simplified. Further, since the structure is simple, it is possible to reduce the size.

  In the above configuration, the flow path wall has a cylindrical shape, and the plug body has a hollow cylindrical portion that is press-fitted into the cylindrical flow path wall. It is preferable.

  In such a configuration, since both the flow path wall and the plug body portion are easily elastically deformed in the radial direction and the discharge flow path is opened / closed, the gas from the outside into the housing body It is possible to ensure a sufficient flow of contents while effectively preventing the inflow of liquid.

  In the above-described configuration, the flow path wall has a cylindrical shape, and the plug body includes a solid portion that is inserted into the cylindrical flow path wall, and an outer peripheral surface thereof. It is preferable that a plurality of annular protrusions that are in pressure contact with the flow path wall are provided along the longitudinal direction.

  In such a configuration, the contact area between the outer peripheral surface of the plug portion and the inner peripheral surface of the flow path wall can be reduced by the annular protrusion, thereby reducing the pressure contact force between these peripheral surfaces. For this reason, it is possible to easily allow the contents to flow out of the housing body by releasing the close contact between the peripheral surfaces with a small pressing force.

  Moreover, in the above-described configuration, it is preferable that the plug body portion has a locking unit that locks and fixes the plug body portion with respect to the spout port portion and restricts the axial movement of the plug body portion.

  According to such a configuration, since the relative movement in the axial direction of the plug part with respect to the flow path wall is restricted, the pressing force of the contents is applied to the flow path wall (or the flow path wall and the plug part). It can be efficiently converted into a radial deformation, and sufficient outflow of the contents can be ensured.

  Moreover, in the above-mentioned structure, it is preferable that the said plug body part has a communication means for connecting the said accommodating part to the said extraction flow path.

  According to such a structure, it becomes possible to ensure the extraction flow path blocked | interrupted by providing a locking means in a plug part by a communication means.

In addition, the present invention is a plug body that is detachably attached to a spout portion of a storage container that stores a predetermined content, and is disposed inside the plug body so as to pour out the content to the outside. A hollow flow channel wall that forms an extraction flow channel for the above, and a plug body portion that is disposed inside the flow channel wall and has an outer surface that is pressed against the inner surface of the flow channel wall, The flow path wall and / or the plug part is formed of a material that is easily elastically deformed in the radial direction, and the flow path wall and the plug part are separated by the pressing force of the contents accompanying the external pressure with respect to the storage container. The extraction flow path is secured by being spread out, and the inner surface of the flow path wall and the outer surface of the plug body are pressed against each other by the restoring force of the flow path wall and / or the plug body accompanying the release of the external pressure. Thus, the plug body is characterized in that the pouring channel is closed.

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

  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, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 are configuration diagrams of a container with a spout according to the first embodiment of the present invention, and FIG. 1 is a schematic perspective view showing a main structure of the container with a spout according to the present embodiment. FIG. 2 is a perspective view of a plug body portion constituting the spout of the spout-equipped container of the present embodiment, and FIG. 3 is an assembly in which the plug body portion is arranged in the flow path wall of the spout portion of the spout of the present embodiment. 4 is a sectional view of the state (closed state), and FIG. 4 is expanded from the closed state of FIG. 3 in the radial direction so that the inner surface of the flow path wall is separated from the outer surface of the plug body by the pressing force of the contents. It is sectional drawing which shows the state by which the extraction flow path was ensured. In FIG. 4, the deformation state of the flow path wall and the plug body is shown in a deformed manner in order to easily explain the operation.

  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, for example, by stacking sheet-like members 8a, 8b made of a relatively flexible material such as synthetic resin and welding (thermal welding) them around. Is done. 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 out of the housing body 1a and pouring the contents to the outside, and attachment portions attached to the respective sheet-like members of the housing body 1 7. In this case, as shown in FIG. 1, a screw portion 21 for screwing a cap is formed on the outer peripheral surface of the spout portion 6 so that a closure body such as the cap 20 is detachably attached to the spout portion 6. May be. In addition, about such a cap 20, it is also possible to exclude by the spontaneous occlusion function of this embodiment mentioned later.

  The sheet-like members 8a and 8b are flexible synthetic resin sheets (plastic films) as described above, and are made of, for example, 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.

  Further, the spout 5 of the present embodiment has a flow path wall 6b extending so as to rise substantially coaxially from the inner peripheral surface base of the mouth body 6a inside the cylindrical mouth body 6a constituting the spout portion 6. I have. In this case, the flow path wall 6b is formed in a cylindrical shape having a circular cross section so as to be easily elastically deformed in the radial direction as will be described later.

  The flow path wall 6b forms a partition between the opening 11 (external environment) of the spout portion 6 and the inside of the storage portion S of the storage body 1, and the discharge flow path 17 is formed by the inner hole portion thereof. It is formed. That is, the flow path wall 6b is configured as a hollow tubular body so as to form an extraction flow path 17 for communicating the contents accommodated in the accommodating portion S to the outside. In this case, the flow path wall 6b is formed of a material (for example, resin, rubber, etc.) that can be deformed in the radial direction by the pressing force of the contents in the accommodating portion S, and the inner peripheral surface of the mouth portion main body 6a. The annular space 18 is disposed substantially coaxially with the annular space 18, and the annular space 18 is allowed to deform outward in the radial direction.

  A plug body 10 as shown in FIG. 2 is arranged inside the flow path wall 6b. The plug part 10 is formed of a material (for example, resin, rubber, etc.) that can be deformed by the pressing force of the contents in the accommodating part S, and the outer surface thereof is a hollow that is pressed against the inner surface of the flow path wall 6b. A tubular plug body 10a, a hollow fitting portion 10b fitted into the inner hole of the attachment portion 7 of the spout 5, and an attachment provided on the outer periphery of the lower end of the fitting portion 10b and facing the accommodating portion S And a flange-like locking portion (locking means) 15 that is locked to the peripheral edge of the opening of the portion 7.

  Note that either one of the flow path wall 6b and the plug body 10 may be formed of a material that is easily elastically deformed in the radial direction (in the present embodiment, both are elastically deformed in the radial direction). Made of easy-to-use materials). Moreover, although the flow path wall 6b and the plug body part 10 may be the same length in the axial direction, as shown in the figure, by increasing the length of the plug body part 10 to be fitted inside, The contents flowing along the flow path wall 6b can be easily guided, and a stable pouring operation can be performed from the upper end opening 11 of the pouring port portion 6.

  Further, the plug body 10a of the present embodiment is formed in a hollow shape, and deformation to the inside in the radial direction is allowed by the hollow portion 12 serving as an inner hole. Moreover, the fitting part 10b has the opening part 13 opened toward the inside of the accommodating part S, and the content in the accommodating part S flows into this part. Moreover, the flange-shaped latching | locking part 15 provided in the lower end outer periphery of the fitting part 10b latches the plug part 10b with respect to the spout part 6 side (specifically, the attaching part 7 of the spout 5). It fixes and fulfill | performs the function which controls the motion of the axial direction of the plug part 10. FIG.

  In addition, on the inclined upper surface, which is a transition region from the fitting portion 10b to the plug body 10a, as a communication means for communicating the inside of the accommodating portion S (and thus the hollow portion of the fitting portion 10b) to the extraction flow path 17. (Specifically, provided at a predetermined interval along the circumferential direction of the inclined upper surface), and between the inclined upper surface and the inner surface of the flow path wall 6b, A substantially annular gap 42 is formed for facilitating the outflow of the contents into the pouring channel 17 through the pouring port 19 (see FIG. 3).

  In the spout-equipped container 1 configured as described above, first, when external pressure is applied to the storage body 1a by, for example, pinching the storage body 1a by hand, the contents P are stored in the storage part along with the external pressure. Extruded from within S. As shown in FIG. 4, the extruded content P flows into the opening 13 of the fitting portion 10b and flows into the gap 42 through the spout 19 of the fitting portion 10b. From there, the channel wall 6b is further expanded (expanded) radially outward so as to be separated from the plug body 10a of the plug body 10 by a pressing force, and the plug body 10a of the plug body 10 is flowed through the flow path. By contracting radially inward so as to be separated from the wall 6b, an extraction flow path S ′ for the contents P is secured.

  Note that the amount (outflow amount) of the content P at this time can be adjusted by controlling the internal pressure (clamping pressure) in the housing main body 1a. Thus, when the extraction flow path S ′ is secured between the inner surface of the flow path wall 6 b and the outer surface of the plug body 10 a, the contents in the housing body 1 a flow out from the upper end opening 11 of the spout portion 6. To do.

  On the other hand, when the external pressure applied to the housing main body 1a is released, the pressing force acting on the inner surface of the flow path wall 6b and the outer surface of the plug main body 10a disappears. Due to the restoring force, the outer surface of the plug body 10a and the inner surface of the flow path wall 6b are pressed against each other, and the extraction flow path S ′ is closed. By releasing the external pressure, the outer surface of the plug main body 10a and the inner surface of the flow path wall 6b are in pressure contact with each other as described above, so that the outside air does not enter the housing portion S. That is, the content P flows out by applying an external pressure to the housing main body, but at this time, the outside air does not enter the housing portion S, and the external flow is immediately released, so that the discharge channel is immediately discharged. Is blocked, the contents P and the outside air do not react.

  Moreover, according to the above-described configuration, it is possible to prevent the contents P from flowing out even if the container 1 falls after opening. Furthermore, since the above-described spontaneous occlusion function is provided, the cap 20 as shown in FIG. 1 can be omitted, and therefore it is not necessary to perform processing for attaching the cap on the spout. The manufacturing cost of the whole body can also be reduced. Moreover, since it is a simple structure which only inserts and locks the plug part 10 in the flow-path wall 6b, shaping | molding is easy and an assembly | attachment operation | work is also simplified. Further, since the structure is simple, it is possible to reduce the size.

  Moreover, in this embodiment, when both the flow-path wall 6b and the plug part 10 (plug main body 10a) elastically deform, the extraction flow path is open | released, and the flow-path wall 6b and the plug part 10 (plug main body) 10a) is elastically pressed together to close the pouring channel, so that the reaction is good and sufficient content can be obtained while effectively preventing the inflow of gas or liquid into the housing body 1a. The flow of things can be secured.

  Moreover, in this embodiment, since the relative movement of the axial direction of the plug body part 10 with respect to the flow-path wall 6b is controlled by the latching | locking part 15, the pressing force of the content P is used for the flow-path wall 6b and the plug-body part. 10 (plug body 10a) can be efficiently converted into a deformation in the radial direction, and the content P can be sufficiently discharged.

  5 to 9 show a second embodiment of the present invention. In the container 1A with a spout of this embodiment, the plug body of the above-described embodiment forms a solid structure. That is, as shown in FIG. 6, the plug body 30 of this embodiment is a hollow plug body 30 a having a substantially cylindrical shape and a hollow fitted into the inner hole of the attachment portion 7 of the spout 5. Fitting portion 30b, and a flange-like locking portion (locking means) that is provided on the outer periphery of the lower end of the fitting portion 30b and that is locked to the peripheral edge portion of the opening of the attachment portion 7 facing the housing portion S 15). In this case, the fitting part 30b has the same structure as the fitting part 10b of the first embodiment.

  In the present embodiment, a plurality of annular protrusions 32 are provided on the outer peripheral surface of the plug body 30a of the plug body 30 along the longitudinal direction. The outer surface of the annular protrusion 32 is in pressure contact with the inner surface of the flow path wall 6b, and a predetermined gap is secured between the outer surface of the flow path wall 6b and the portion other than the annular protrusion 32. I am doing so.

  In this case, the annular protrusion 32 of the present embodiment forms a ring shape having a substantially rectangular longitudinal section, but can have various shapes as shown in FIG. That is, the annular protrusion 32 is not limited to the ring-shaped annular protrusion 32 whose longitudinal section is substantially rectangular as shown in FIG. 9A, and the longitudinal section as shown in FIG. An annular projection 32A, an annular projection 32B whose longitudinal section is a substantially isosceles triangle as shown in FIG. 9 (c), or an annular projection whose longitudinal section is a substantially right triangle as shown in FIG. 9 (d). It can be configured as 32C.

  Note that configurations other than those described above are the same as those in the first embodiment, and the same reference numerals are assigned and description thereof is omitted.

  In the spouted container 1A having such a configuration, the flow path wall 6b is pushed away so as to be separated from the plug body part 10 (plug body 10a) by the pressing force of the contents P accompanying the external pressure on the storage body 1a. A pouring channel for the contents P is secured (the plug body 10a is not deformed). On the other hand, when the external pressure applied to the housing main body 1a is released, the inner peripheral surface of the flow channel wall 6b becomes the outer peripheral surface of the plug main body 10a (the outer surface of the annular protrusion 32) by the elastic restoring force of the flow channel wall 6b. The discharge channel is closed by the pressure contact.

  Therefore, according to the present embodiment, substantially the same operational effects as those of the first embodiment can be obtained, and due to the presence of the annular protrusion 32, the outer peripheral surface of the plug body 10a and the inner peripheral surface of the flow path wall 6b. The contact area between the peripheral surfaces can be reduced, thereby reducing the pressure contact force between these peripheral surfaces, so that the close contact between the peripheral surfaces is released with a small pressing force, and the contents P are placed outside the housing body 1a. It can be easily drained.

  FIG. 10 shows an independent plug body having the spout structure described above, and an embodiment in which this plug body can be detachably attached to any existing storage container.

  Specifically, the plug body 50 of the present embodiment is detachably attached to the spout portion 60a of the storage container 60 for storing predetermined contents by screwing, press fitting, or the like. It has the same internal structure as the spout 5 of the first embodiment or the second embodiment.

  That is, the plug body 50 of this embodiment is disposed inside the hollow flow path wall 6b that forms a flow path for communicating the inside of the storage container 60 to the outside, and the outer surface of the flow path wall 6b. And a plug body portion 10 that is pressed against the inner surface of the road wall 6b. And like the above-mentioned embodiment, the flow path wall 6b is pushed away so that it may separate from the plug part 10 with the pressing force of the content accompanying the external pressure with respect to the storage container 60, and the extraction flow path of a content is ensured. The pouring flow path is closed by the inner surface of the flow path wall 6b being pressed against the outer surface of the plug body 10 by the elastic restoring force of the flow path wall 6b.

  According to such a stopper 50, it is possible to freely apply the structure having the above-described characteristics to any existing container 60. Note that a closing cap 70 may be attached to the plug 50 by screwing or the like.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously. For example, the flow path wall 6b disposed inside the spout may have an elliptical shape or a polygonal shape other than a circular cross section. Along with this, the shape of the plug body can be appropriately modified.
