Description

  The present invention relates to a container in which sheets of flexible synthetic resin are stacked, and in detail, a spout (called a spout) integrally formed with resin or the like is welded to pour out the container. It relates to a container with a spout that has been made possible.

  2. Description of the Related Art Conventionally, a container in which synthetic resin sheet-like members (plastic film) are stacked and the peripheral portions thereof are welded (thermally welded) is known. Such a container is inexpensive, lightweight, and easy to handle. Therefore, the container is used in various fields such as medical fields, daily necessities such as cosmetics and sanitary goods, office supplies, and foods. By the way, in such a container, an anaerobic liquid may be stored, and such a container may be left as it is after being opened and poured out. It is preferable to have a reseal structure so that inflow of outside air can be prevented.

  For example, Patent Document 1 discloses a container having an adhesive nozzle formed as having such a reseal structure. This nozzle is constructed so that two sheets of flexible sheets are stacked and the inner surface thereof is in close contact after filling the container, and after the internal pressure of the container is raised and the container is poured out, The at least one flexible sheet is bent so that the degree of adhesion can be increased and resealed.

JP 2001-192045 A

  The container described above has a nozzle so that the nozzle part is always in close contact with the container in a normal state after filling the container, and at least one side is bent to obtain a sealing property after the container is poured out. Since it is a structure which provides the boundary line used as a crease to the flexible sheet | seat which comprises, it is not easy to manufacture and will also raise manufacturing cost. Further, in the normal state after the actual dispensing operation, the contents are held inside the container only by the contact area between the sheets, so that the close contact function (seal function) is not sufficiently performed and the internal storage is performed. The possibility of things leaking out cannot be denied.

  The present invention has been made paying attention to the above-mentioned problems, and can reliably prevent the outside air from flowing into the housing portion after the contained material is poured out, and can improve the reseal performance after the contained material is poured. An object of the present invention is to provide a spouted container that can prevent dripping of an object.

  In order to achieve the above-described object, the present invention provides an accommodation main body that forms an accommodation portion in which an accommodation is accommodated by stacking sheet-like members and welding the periphery thereof, and is interposed in the sheet-like member, And a spout with a spout that forms an outlet for allowing the contents in the section to flow out, wherein the spout includes a partition that divides the interior into two compartments, and the sheet. A welded region that is welded to the sheet-shaped member, and a close-contact region that is in contact with the sheet-shaped member without being welded across the two compartments so as to be surrounded by the welded region. The first compartment of the spout that is partitioned by a partition wall communicates with the inside of the housing portion, and has a spout for pouring out the contents in the housing portion in the close contact area, The second compartment of the spout partitioned by a wall is opened to the outside through the outflow port, and an inflow port for receiving the contents to be poured out from the outflow port through the close contact region. It is characterized by having.

  According to the above configuration, for example, when a pressing force is applied to the storage portion, the stored item in the storage portion that receives the pressing force is in close contact with the spout in the contact region through the first compartment ( The sheet-like member that closes the spout in the contact area is pressed. Then, by this pressing force, the sheet-like member in the close contact region is separated from the peripheral side surface of the spout (the sheet-like member is pushed and spread), and the spout and the inflow port are opened. The space between the spout and the peripheral surface of the spout that is poured out through the spout opened from the chamber and the close contact state (between the spout and the inlet by the sheet-like member being expanded) From the inflow port to the second compartment through the flow path for the contained material formed in the, and out to the outside through the outflow port. After that, when the pressing force acting on the housing portion is released, the pressing force acting on the sheet-like member is also released, so the sheet-like member in the close contact area is again in close contact with the peripheral side surface of the spout and closes the spout and inlet. To become. Accordingly, it is possible to reliably prevent the outside air from flowing into the housing part after the contained material is poured out.

  Moreover, according to the said structure, while the accommodating part of an accommodating main body is isolated from the exterior by the partition, it is further isolated from the exterior also by the contact | adherence area | region of a spout and an inflow port, and a sheet-like member. That is, the accommodating part is in a state isolated from the outside in two stages. Therefore, the sealing performance after the contents are poured out can be dramatically improved as compared with the conventional case (for example, Patent Document 1 in which the contents are held inside the containing main body only by the contact area between the sheets). It is possible to prevent leakage of the contents after it is released. In the above configuration, since the spout is open to the outside at the outlet (exposed to the outside), the suck back effect (when the spout and the inlet are closed, the contained matter is caused by the pressure difference with the outside air). The effect of being sucked into the housing portion is also obtained, and reliable resealability and leakage resistance can be ensured. In addition, when the spout is exposed to the outside at the outlet, it becomes possible to attach a closing cap to the outlet of the spout, and by doing so, the housing portion is securely cut off from the outside. It is also possible to do. In addition, the above-described configuration can be easily manufactured because it is only necessary to provide a spout with a partition wall to form the spout and the inflow port in order to realize the above-described effects.

  Moreover, in the said structure, it is preferable that a 2nd division chamber forms the storage chamber which stores an accommodation thing after the outflow of the accommodation thing through an outflow port. If it does in this way, it will also become possible to always store a fixed quantity of a thing in the 2nd division room every time it pours out a thing, and the weighing function of a thing can be obtained.

  According to the present invention, not only can the outside air be surely prevented from flowing into the housing part after the contained material is poured out, but also the resealing performance after the contained material is poured out and the leakage of the contained material can be prevented easily. A spouted container is obtained.

Hereinafter, an embodiment of a container with a spout according to the present invention will be described with reference to the drawings.
1-3 is a figure which shows one Embodiment of the container with a spout which concerns on this invention, FIG. 1 is sectional drawing and figure which show the whole structure of the container with a spout which concerns on one Embodiment of this invention. 2 is an enlarged cross-sectional view of the main part of the spout welded portion of the container with spout of FIG. 1, and FIG. 3 is an enlarged perspective view of the spout welded to the housing body.

  The spout-equipped container 1 according to the present embodiment is configured, for example, in a form as shown in FIG. 1, and the storage main body 2 formed by overlapping sheet-shaped members 2 a and 2 b having a predetermined shape, And a spout 20 that is interposed between the sheet-like members 2a and 2b and for pouring out the contents accommodated in the accommodating portion S of the accommodating main body 2.

  Each of the sheet-like members 2a and 2b includes an upper edge portion 5, side edge portions 6 and 7, a lower edge portion 8, and a spout attachment edge portion 9 formed one step lower than the upper edge portion 5. The housing body 2 is formed by thermally welding the portions 5, 6, 7, 8, and 9 by a heat bar (not shown) (the welded portion is indicated by a hatched area). In the present embodiment, when the lower edge portion 8 is welded, the bottom portion 8a is welded and is configured as a self-solid body. However, a non-self-solid body that is simply welded to the peripheral portions of the sheet-like members 2a and 2b ( It may be configured as a bilateral, a trigonal, etc.

  That is, with respect to the housing main body 2, the parts to be welded, the arrangement of the sheet-like members constituting the bag body, the shape of the housing portion S, and the like can be appropriately modified depending on the intended use, etc. It is not limited to. Further, a cut-out line C for exposing the spout 20 to the outside is provided at a portion of the upper edge portion 5 and the side edge portion 6 corresponding to the position of the spout attachment edge portion 9 so as to be broken.

  The sheet-like members 2a and 2b are made of a flexible synthetic resin sheet (plastic film), for example, polyethylene or polypropylene so as to be easily welded. It is composed of a so-called composite layer in which nylon, aluminum foil, etc. are laminated so as to increase the resistance.

  Moreover, a part of the edge parts 5, 6, 7, 8, 9 and in this embodiment, a part of the upper edge part 5 may be unwelded to form an opening. In that case, the accommodation can be filled into the accommodation portion S of the accommodation body 2 through this opening. In addition, the upper edge part 5 is welded after filling.

  A cylindrical spout 20 that forms an outlet 20a for allowing the contents filled in the accommodation portion S to flow out is welded to the spout attachment edge portion 9 of the sheet-like members 2a and 2b. Here, with reference to FIG. 2 and FIG. 3, the structure of the spout 20 interposed in the spout attachment edge part 9 of the sheet-like members 2a and 2b is demonstrated.

  The spout 20 to be welded is integrally formed of, for example, a synthetic resin such as polyethylene or polypropylene, and is welded between the sheet-like members 2a and 2b. Further, the spout 20 includes a partition wall 30 that divides the interior into two upper and lower compartments 20A and 20B. In addition, in this embodiment, although the inside of the spout 20 is partitioned up and down by the partition 30, you may partition into right and left, and a partition direction is not specifically limited. In the present embodiment, the space to be partitioned is a cylindrical space, but a space having an arbitrary shape may be partitioned (the shape of the spout 20 is not limited to a cylinder).

  Further, the spout 20 extends across the two compartments 20A and 20B so as to be surrounded by the welding region 40 (the portion indicated by hatching in FIG. 2) welded to the sheet-like members 2a and 2b and the welding region 40. It has a close contact area 42 (portion shown in white in FIG. 2) on its peripheral side surface. In this case, the close contact region 42 of the spout 20 is a portion where the sheet-like members 2a and 2b are in close contact (or pressure bonded) without being welded.

  The welding region 40 only needs to be shaped so as to be easily welded to the inner surfaces of the sheet-like members 2a and 2b. For example, the cross section corresponds to a boat shape, an elliptical shape, or a circular shape (a cross section having a substantially boat shape). Collectively referred to as shape). The superposed sheet-like members 2a and 2b are welded to the welding region 40 of the spout 20 interposed between the sheet-like members 2a and 2b by a heat bar (not shown).

  The first compartment 20A on the lower side of the spout 20 partitioned by the partition wall 30 communicates with the housing portion S of the housing body 2 and has a spout 24 for pouring the contents in the housing portion S. The contact area 42 is provided. In the present embodiment, the two spouts 24 are provided on both sides of the peripheral side surface of the spout 20, for example, 180 degrees apart in the circumferential direction, but the number of spouts 24 is not limited to two, The arrangement form of the spout 24 is not limited to the opposite position. In short, it is sufficient that one or more spouts 24 are provided in the close contact region 42 corresponding to the first compartment 20A.

  The second compartment 20B on the upper side of the spout 20 partitioned by the partition wall 30 is opened to the outside through the outlet 20a, and the contents poured out from the spout 24 of the first compartment 20A are adhered to the close contact area. An inlet 22 for receiving via 42 is provided in the contact area 42. In the present embodiment, the two inlets 22 are provided at 180 degrees apart in the circumferential direction on both sides of the peripheral side surface of the spout 20 in a state where the two inlets 22 are substantially aligned with the corresponding outlets 24 in the vertical direction. The number of 22 is not limited to two, and the arrangement form of the inflow ports 22 is not limited to the opposite positions. In short, it is sufficient that one or more inflow ports 22 are provided in the close contact region 42 corresponding to the second compartment 20B.

  In the present embodiment, the inflow port 22 and the spout 24 are provided substantially flush with the peripheral side surface of the spout 20, but a convex portion that protrudes radially outward from the peripheral side surface of the spout 20 is provided. The inlet 22 and the spout 24 may be formed at the tip of the part. In that case, it is preferable to form the tip of the convex part on a flat surface so that the inner surfaces of the sheet-like members 2a and 2b are in close contact with each other. In such a configuration, since the sheet-like members 2a and 2b are elastically stretched radially outward by the convex portions, the sheet-like members 2a and 2b are formed on the tip surfaces of the convex portions in the close contact region 42. The inlet 22 and the outlet 24 can be closed in a sufficiently sealed state by being pressed by the tensile force.

Next, with reference to FIGS. 4-6, the effect | action of the container 1 with a spout of the said structure is demonstrated.
First, when the stored matter 60 (see FIG. 5) accommodated in the accommodating portion S of the spout-equipped container 1 having the above-described structure is poured out (flowed out), the upper edge is taken along the cut line C in FIG. The part 5 and a part of the side edge 6 are broken to expose the spout 20 to the outside.

  Thereafter, when a pressing force is applied to the storage portion S of the storage main body 2, the storage object 60 in the storage portion S that receives this pressing force, as shown by the arrows in FIGS. Through the compartment 20A, the sheet-like members 2a and 2b that are in close contact with the spout 20 in the close contact region 42 (which closes the spout 24 in the close contact region 42) are pressed. And by this pressing force, the sheet-like members 2a and 2b in the contact area 42 are separated from the peripheral side surface of the spout 20 (the sheet-like members 2a and 2b are pushed and spread), and the spout 22 and the inflow port 24 are opened. (See FIG. 6B).

  Thereby, the container 60 flows out from the first compartment 20A through the opened spout 24, and the space between the sheet-like members 2a and 2b released from the close contact state and the peripheral side surface of the spout 20 ( The sheet-like members 2a and 2b are expanded and the second compartment 20B on the upper side from the inflow port 22 via a flow path for the container 60 formed between the spout 24 and the inflow port 22). And flows out to the outside through the outlet 20a. The filling state of the compartments 20A and 20B of the accommodation 60 at this time is shown by oblique lines and crossing lines in FIG.

  And after releasing the pressing force which acts on the accommodating part S by pouring out such a stored material 60, it becomes possible to store the stored material 60 as it is in the 2nd compartment 20B. At this time, since the pressing force acting on the sheet-like members 2a and 2b is released, the sheet-like members 2a and 2b in the close contact region 42 again come into close contact with the peripheral side surface of the spout 20 to close the spout 24 and the inlet 22. Therefore, it is possible to reliably prevent the outside air from flowing into the accommodating portion S after the contents are poured out (the sealing effect by the second compartment and the reliable contact of the sheet-like member with each other). Sealing effect).

  As described above, according to the spouted container 1 of the present embodiment, the housing portion S of the housing body 2 is isolated from the outside by the partition wall 30, and the spout 24, the inlet 22 and the sheet-like member. It is further isolated from the outside by the contact area 42 with 2a, 2b. That is, since the accommodating part S is in a state isolated from the outside in two stages, the sealing performance after the article is poured out is conventionally improved (for example, the contents are accommodated only in the contact area between the sheets inside the main body. Compared to Patent Document 1) held in the above, the re-seal performance after the container is poured out can be improved, and the leakage of the container after the container is poured out can be prevented.

  In this embodiment, since the spout 20 is opened to the outside at the outlet 20a (exposed to the outside), the suck back effect (pressure with the outside air when the spout 24 and the inlet 22 are closed) The difference (the effect that the contained material 60 is sucked into the housing portion S) is also obtained, and a reliable resealability is obtained, and dripping can be reliably prevented.

  Further, a closing cap (not shown) can be attached to the outflow port 20a of the spout 20, thereby making it possible to reliably block the accommodating portion S from the outside. Furthermore, in the configuration of the present embodiment, since it is only necessary to provide the partition wall 30 in the spout 20 and form the spout 24 and the inflow port 22 in order to realize the above-described effects, the manufacture is easy.

  Moreover, in this embodiment, since the 2nd division chamber 20B forms the storage chamber which stores the things 60 after the outflow of the things 60 through the outflow port 20a (refer FIG. 5), the things 60 are stored. Each time it is dispensed, the second compartment 20B can always store a certain amount of the stored item 60 (indicated by a cross line in FIG. 5), and the weighing function of the stored item 60 can be obtained. In the present embodiment, the spout 24 and the inflow port 22 are formed on both sides of the circumferential side surface of the spout 20 in a state where the spout 24 and the inflow port 22 are substantially aligned with each other. An outflow can be realized.

  In addition, this invention is not limited to embodiment mentioned above, It can be implemented in various deformation | transformation. For example, in the embodiment described above, the spout 20 is attached (welded) to the spout mounting edge 9 formed one step lower than the upper edge 5 of the housing body 2, but the edges of the sheet-like members 2 a and 2 b. The attachment position of the spout 20 to be welded can be changed as appropriate according to the shape of the housing body 2. The overall configuration of the spout 20, the shape of the welding region 42, the positions of the outlets 20 a, the outlets 24, and the inlets 22, and the number of formed parts can be modified as appropriate. In the embodiment described above, the interior of the spout 20 is partitioned into two compartments by one partition 30. However, the spout 20 may be partitioned into three or more compartments by a plurality of partitions. Two compartments may be present inside the spout 20.
