  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 includes a spout part for pouring the contents to the outside and an attachment part attached to the housing body. In the spout portion, a guide member having a spout end portion through which the content is poured out and a guide portion that forms a guide channel for guiding the content toward the spout end portion is disposed. A slit is formed at the dispensing end of the guide member, and an elastic body that opens the slit by elastic deformation is provided. In the dispensing end of the guide member, an external pressure is applied to the housing body. By the pressing force of the contents accompanying Dynamic and characterized in that the pressing body is provided for opening the slit by pressing the elastic body.

  According to the above-described structure, the elastic body at the extraction end portion of the guide member is elastically pressed by the pressing body that moves due to the pressing force of the contents accompanying the external pressure with respect to the housing body, and is formed into the elastic body. Open the slit. By opening the slit, the contents can be poured out through the slit. On the other hand, when the external pressure on the housing body is released, the pressing force by the pressing body is released, the slit is closed by the elastic restoring force of the elastic body, and the extraction flow path is sealed. Therefore, when taking out the contents via the spout, it is possible to prevent a situation in which gas, liquid, or the like flows from the outside into the housing body and the properties of the contents change. That is, at the time of the pressing, the content is saturated inside the flow path, and the blocking function acts simultaneously with the pressure reduction, so that it is possible to prevent the outside air from flowing into the flow path from the outside.

  In the above-described configuration, an insertion port portion into which the pressing body is inserted is formed at the extraction end portion of the guide member, and the insertion port portion is opened by the movement of the pressing body to pour contents. It is preferable to secure an outlet channel.

  In such a configuration, the flow of the contents is opened and closed by the slit and the insertion opening in two stages (by providing a double flow opening / closing portion), thereby improving the sealing performance and improving the inside of the housing body. It is possible to effectively prevent inflow of outside air or the like.

  Moreover, in the above-mentioned structure, it is preferable to further have a guide means for guiding the contents in the housing main body to the fitting inlet portion.

  In such a configuration, since the contents are reliably guided to the fitting inlet by the guide means, the fitting inlet and thus the slit can be efficiently opened, and the contents can be poured out without waste.

  In order to achieve the above-described object, the present invention provides a plug body that is detachably attached to a spout part of a storage container that stores a predetermined content. A guide member having a dispensing end portion to be dispensed and a guide portion that forms a guide flow path for guiding the contents in the container toward the dispensing end portion is provided inside the guide member. A slit is formed at the dispensing end, and an elastic body that opens the slit by elastic deformation is provided, and the content of the contents accompanying the external pressure with respect to the storage container is placed in the dispensing end of the guide member. A pressing body that is moved by a pressing force and presses the elastic body to open the slit is provided.

  FIG. 1 shows a substantially upper half of the spouted container 1. 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. ing. In this case, the welded portion is indicated by the hatched portion 3, and 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 a generally oval cross-section attached to each sheet-like member of the housing body 1a. And a landing portion 7.

  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.

  Further, the spout 5 of the present embodiment is integrally formed with a guide member 10 extending along the outflow direction in the spout portion 6. The guide member 10 includes a seal body 10B that seals the inside of the housing main body 1a from the outside at the base of the spout portion 6, and a substantially spherical pouring end for pouring the contents in the housing main body 1a. 10C (see FIG. 2) and a guide channel 12 (see FIGS. 3 to 5) that penetrates the seal body 10B and communicates with the inside of the housing main body 1a and guides the contents toward the dispensing end 10C. And a guide portion 10A.

  The guide member 10 is integrally formed with the spout 5 so that the pouring end portion 10C is positioned in the vicinity of the upper end opening 6a of the pouring port portion 6. In this case, since the dispensing end portion 10C has a substantially spherical shape, it is easy to remove the mold when molding. Note that the guide member 10 may be formed as a separate body from the spout 5 and may be inserted into and fixed to the spout portion 6. In such a structure, the seal body 10B of the guide member 10 may be formed of an elastic body such as rubber so that it can be easily fitted into the spout portion.

  An elastic body 20 that is elastically deformable is attached to the extraction end portion 10C of the guide member 10A. Specifically, the elastic body 20 is formed as a hollow rubber cap having a substantially spherical outer shape in accordance with the shape of the dispensing end portion 10C, and as shown in FIG. It has the part 20b and the upper end obstruction | occlusion film | membrane 21 which has elasticity. A slit 20a is formed in the upper end closing film 21 so as to be elastically expandable, and the elastic body 20 is placed on the outer periphery of the extraction end portion 10C of the guide member 10 through the lower opening 20b. It is designed to be fitted. When the elastic body 20 is actually fitted and attached to the outer periphery of the dispensing end portion 10C, the upper end closing film 21 covers the upper end opening 19 of the dispensing end portion 10C, and the upper end opening 19 is blocked.

  As shown in FIGS. 3 to 5, a pressing body 30 is provided in the extraction end portion 10 </ b> C of the guide member 10, and can be moved by the pressing force of the contents accompanying the external pressure with respect to the housing body 1 a. The pressing body 30 has a function of pressing the elastic body 20 (specifically, the upper end closing film 21) by moving by the pressing force of the contents and opening the slit 20a formed therein. . Specifically, the pressing body 30 is integrally formed of, for example, a synthetic resin or the like, and as shown in FIGS. 2C and 3, a circular disc-shaped main body portion 30 b and a lower portion from the main body portion 30 b. A fitting portion 30a having a substantially triangular pyramid shape extending toward the side, and the upper surface of the main body portion 30b abuts against the upper end blocking film 21 when the pressing body 30 moves, so that the slit 20a And a flow path (gap) 35 through which the content passes when the slit 20a is opened.

  The pressing portion 32 is formed to protrude from the upper surface portion of the main body portion 30b at a predetermined interval (approximately 180 ° interval) in the circumferential direction, and along a direction substantially orthogonal to the extending direction of the slit 20a. A pair is formed. Specifically, the pressing portion 32 is provided so as to project substantially vertically upward from the upper surface of the main body portion 30b, and the upper surface has a taper portion 32a as a pressing action portion extending obliquely upward toward the radial inner side. It has.

  In addition, the flow path 35 is defined by a gap between the protrusion 33 projecting from the upper surface of the main body 30b and extending substantially vertically upward and the pressing portion 32. That is, a pair of protrusions 33 are formed along the extending direction of the slit 20 a, and a substantially cross-shaped flow path (gap) 35 is formed between the protrusions 33 and the pressing part 32. In this case, even if the pressing body 30 moves, the upper surface of the protrusion 33 does not contact the upper end blocking film 21.

  Moreover, in this embodiment, the insertion part 15 is formed so that the insertion part 30a of the press body 30 may be inserted in 10 C of extraction | drawer end parts of the guide member 10. FIG. The insertion port 15 is formed as a substantially triangular pyramid-shaped inner hole that tapers downward so as to correspond to the shape of the insertion portion 30a of the pressing body 30, and as shown in FIG. It is formed in a shape that can receive the fitting portion 30a of the pressing body 30 inserted through the upper end opening 19 of the end portion 10C (see FIGS. 4 and 5). Then, as will be described later, when the inserted pressing body 30 is pushed up and moved, the insertion port 15 secures a pouring channel through which the contents pass with the insertion portion 30a. ing.

  Further, in the present embodiment, guide means 13 for guiding the contents in the housing main body 1a to the fitting inlet portion 15 is provided in the extraction end portion 10C of the guide member 10 as shown in FIG. Is provided. The guide means 13 can be formed integrally with the dispensing end portion 10 </ b> C, and is configured by an inner surface that has a substantially dome shape that gradually narrows toward the fitting inlet portion 15. The top of the dome-shaped inner surface constituting the guide means 13 communicates with the fitting inlet 15 as a connection through hole 17.

  In the container 1 with a spout 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 in the storage body 1a are accompanied by the external pressure. Is pushed out. The extruded content moves through the guide channel 12 of the guide portion 10A of the guide member 10 and efficiently reaches the fitting inlet portion 15 through the guide means 13. The contents that have reached the insertion port 15 push up the pressing body 30 inserted into the insertion port 15 by the pressing force. As a result, the fitting port 15 is opened to secure a flow path for the contents, and the contents can move into the flow path (gap) 35. And the taper part 32a of the upper surface of a pair of press part 32 formed in the main-body part 30b of the press body 30 abuts on both sides of the slit 20a. At this time, since the upper end blocking film 21 can be elastically deformed, both sides of the slit 20a portion are pushed up to open the slit 20a.

  Therefore, the content pushed up through the insertion port 15 flows out from the slit 20a to the outside through the gap 35 formed on the upper surface of the main body 30b of the pressing body 30, as indicated by an arrow in FIG. It becomes possible to do. In addition, about the amount (outflow amount) of the content extraction at this time, it can adjust by controlling the internal pressure (clamping pressure) in the accommodating main body 1a.

  On the other hand, when the external pressure applied to the housing main body 1a is released, the pressing force acting on the pressing body 30 and the elastic body 20 (upper end closing film 21) disappears. And the fitting inlet 15 is closed, and the elastic restoring force of the elastic body 20 closes the slit 20a and seals the extraction channel.

  As described above, according to the spouted container 1 of the present embodiment, the elastic body 20 attached to the dispensing end portion 10C of the guide member 10 is caused by the pressing force of the contents accompanying the external pressure with respect to the storage body 1a. The slit 20a is elastically pressed by the moving pressing body 30, and the content can be poured out through the slit 20a. On the other hand, when the external pressure with respect to the housing main body 1a is released, the pressing force by the pressing body 30 is released, the slit 20a is closed by the elastic restoring force of the elastic body 20, and the dispensing flow path is sealed. Therefore, when taking out the contents via the spout 5, it is possible to prevent a situation in which gas or liquid flows from the outside into the housing body 1a and the properties of the contents change. That is, at the time of pressing, the contents are saturated inside the flow path, and the blocking function acts simultaneously with the pressure reduction, so that the outside air from the outside to the flow path (inside the housing body 1a), etc. Inflow can be prevented.

  Moreover, according to the container 1 with a spout of this embodiment, since the flow path opening / closing of the contents is performed in two stages by the slit 20a and the fitting inlet portion 15 (a double flow path opening / closing section is provided). Therefore, the sealing property can be improved and the inflow of outside air or the like into the housing main body 1a can be effectively prevented.

  Furthermore, according to the spout-equipped container 1 of the present embodiment, the contents are surely guided to the insertion port 15 by the guide means 13, so that the insertion port 15 and thus the slit 20a can be efficiently opened. The contents can be poured out without waste.

  FIG. 7 shows an example in which the spout structure in the above-described embodiment can be detachably attached to any existing storage container, and an independent separate plug body 50 having the spout structure in the above-described embodiment is provided. It can be detachably attached to any storage container.

  Specifically, the plug body 50 of the present embodiment is detachably attached to the spout 40a of the storage container 40 for storing predetermined contents by screwing, press-fitting or the like, and the spout 5 described above. Has the same internal structure. That is, the plug 50 includes a guide member 10, an elastic body 20 with a slit attached to the guide member 10, and a pressing body that presses the elastic body 20 to open the slit. In this case, the lower end of the guide channel 12 of the guide member 10 is opened so that it can communicate with the inside of the storage container 40. Note that a closing cap 60 may be 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.

  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 pressing body 30 is not limited to the shape of the above-described embodiment. If the thin film portion (upper end closing film 21) in which the slit 20a of the elastic body 20 is formed can be pressed and deformed to open the slit, the pressing body 30 has the shape. Is not limited to the configuration shown in the figure. In the embodiment described above, the guide unit 13 is provided, but the guide unit 13 may not be provided. Furthermore, the shape of the slit, the shape of the pressing body that opens the slit, the shape and material of the elastic body in which the slit is formed, and the mounting mode thereof can be appropriately modified.
