  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 can be made.

  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 (thermal welding) 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. In addition, after the actual dispensing operation, the functions as described above may not be sufficiently exhibited, and the sealing performance may not be sufficient.

  The present invention has been made by paying attention to the above-described problems, and can be easily manufactured with a simple structure, and reliably prevents the outside air from flowing into the housing portion when the contained material is poured out. An object of the present invention is to provide a spouted container that can be used.

  In order to achieve the above-described object, the present invention provides a container that accommodates an object by stacking sheet-like members and welding the periphery thereof, and an object contained between the sheet-like members. A spout with a spout, and the spout is provided in a flow path for pouring the stored material to the outside, a first welded portion to which the sheet-like member is welded, and the first welded portion. A main body part integrally formed with a tubular channel cylinder part that protrudes outward in a cylindrical shape with respect to the welded sheet-like member and includes an extraction channel that communicates with the channel. In addition, the outer peripheral surface of the flow path cylinder portion is covered with a bag-like member welded on three sides, and the opening region is welded, and the outer peripheral surface of the flow path cylinder portion and the welding edge of the bag-like member A second welded portion in which the opening region is welded so as to have a gap with the portion. The bag-shaped member is welded to the second welded portion to form a cavity and a close-contact portion in the bag-shaped member, and the distal end portion of the bag-shaped member is cut so that the cavity and the close-contact portion are It is possible to pour out the contents through the door.

  In the spout-equipped container having the above-described structure, the contents are poured out through a bag-shaped member that is welded so as to be covered with a tubular flow path tubular portion that is formed so as to protrude from the main body portion of the spout. Three sides of the bag-like member are welded, and the bag-like member is welded to the second welded portion in a state where the opening side is covered with the channel tube portion. The second welded portion is configured such that when the opening region of the bag-like member is welded, a gap is formed between the outer peripheral surface of the flow path tube portion and the welded edge of the bag-like member, By welding the shaped member to the second welded portion, the bag-like member has a hollow portion (a non-contact portion where the inner surface of the bag-like member is not in close contact) and a close contact portion (a portion where the inner surfaces are in close contact with each other by a tensile force). It is formed. For this reason, by cutting the front end portion of the bag-like member and pressing the container portion to increase the internal pressure, the contents are poured out from the cut and moved portion so as to expand the contact portion from the cavity portion. . When the pressing of the container portion is released, the stored matter is stored in the hollow portion of the bag-like member, and the close contact portion after that recovers the tensile force and comes into close contact again. In this case, the close contact portion is in a state in which a sealing film of the accommodation is formed by capillary force, and the outside air enters the accommodation body side from the opening of the flow path cylinder portion together with the accommodation stored in the cavity portion. Prevents the seal function.

  Moreover, the spout welded to the container has a first welding part for welding the container containing the container in the main body part and a flow path having a second welding part for welding the bag-like member to be poured out. It has a simple structure in which the cylindrical portion is integrally formed, and has a sealing function for welding the container to the integrally formed first welding portion and welding the bag-like member to the second welding portion. The container can be easily manufactured.

  According to the present invention, a spout-equipped container that can be easily manufactured with a simple structure and that can reliably prevent the outside air from flowing into the container when the container is poured out is obtained. It is done.

Hereinafter, embodiments of a container with a spout according to the present invention will be described with reference to the drawings.
1 to 3 are diagrams showing a first embodiment of a container with a spout according to the present invention, FIG. 1 is a diagram showing an overall configuration, and FIG. 2 is a diagram showing an enlarged spout part, FIG. 3A is an enlarged front view showing the spout portion, and FIG. 3B is a side view thereof.

  The spout-equipped container 1 according to the present embodiment is configured, for example, in a form as shown in FIG. 1, and the container 2 formed by superimposing rectangular sheet-like members 2a and 2b, and the sheet And a spout (pour-out port) 10 that pours out the objects 50 accommodated in the accommodating portion S of the container.

  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 enhance the properties.

  The sheet-like members 2a and 2b are accommodated in which the objects 50 are accommodated by heat-welding the hatched regions (upper edge part 5, side edge parts 6 and 7, and lower edge part 8) shown in the drawing with a heat bar. A container 2 having a part S is formed. In this embodiment, when the lower edge portion 8 is welded, the bottom portion 8a is welded and is configured as a self-solid body. However, the non-self-solid body is simply formed by welding the peripheral portions of the sheet-like members 2a and 2b. It may be configured as (dihedral, trigonal, etc.). That is, about the part to weld, arrangement | positioning of the sheet-like member which comprises a bag body, the shape of the accommodating part S, etc., it can change suitably according to a use application etc., It is limited to the structure shown in a figure. Absent.

  When the peripheral edges of the sheet-like members 2a and 2b are welded, the spout 10 is interposed in the upper edge portion 5 thereof. In this case, the spout 10 can be welded by overlapping the sheet-like members 2a and 2b and simultaneously with the above-described surrounding welding process. May be welded. In addition, the contents 50 in the accommodating portion S are partly welded, for example, as shown in FIG. 1, a part 5 a of the upper edge portion 5 is left unwelded and filled from this portion. A spout-equipped container 1 filled with the contents 50 is formed.

  The spout 10 of this embodiment has the main-body part 11 integrally formed, for example with synthetic resins, such as polyethylene and a polypropylene. The main body 11 has a first welded portion 12 to which the sheet-like members 2a and 2b are welded, and a tube facing outward with respect to the sheet-like members 2a and 2b welded to the first welded portion 12. The cylindrical flow path cylinder part 15 which protrudes in the shape is integrally formed. Further, the main body 11 is formed with a flow path 14 that penetrates the inside of the first welded portion 12 and flows out the contents 50 accommodated in the accommodating portion S to the outside. Is communicated coaxially (linearly) with the extraction flow path 15a formed by the flow path cylinder portion 15. As a result, the stored matter 50 accommodated in the accommodating portion S passes through the flow path 14 formed in the main body 11 and the extraction flow path 15a of the flow path cylindrical portion 15 to the tip of the flow path cylindrical portion 15. It is poured out from the opening 15b.

  The first welded portion 12 only needs to be shaped so as to be easily welded to the inner surfaces of the stacked sheet-like members 2a and 2b. For example, the cross section has a boat shape, an elliptical shape, or a circular shape. Accordingly, the upper edge portion 5 of the overlapped sheet-like members 2a and 2b is integrally welded to the surface portion of the welded portion 12.

  The flow path cylinder portion 15 has a predetermined length L and protrudes upward from the upper surface (flat surface) 11a of the main body portion 11 orthogonal to the first welded portion 12, and is formed at that portion. Is the state in which the opening side of the bag-like member 20 to which the three sides (side edges 20a, 20b and bottom edge 20c) are welded is covered and regulated by the upper surface 11a (positioned state), and the inner surface on the opening side is It is heat welded. In this case, the base end side of the flow path cylinder portion 15 is a second welded portion 15c to which the inner surface of the opening side of the bag-like member is thermally welded. The second welded portion 15c includes a bag-like member. The welding protrusion 15d is integrally formed so that a gap G is formed between the outer peripheral surface of the flow path cylinder 15 and the welding edge (side edges 20a, 20b) of the bag-like member when the 20 is welded. ing.

  Specifically, in the present embodiment, the flow path cylinder portion 15 is formed in a circular cross section, and the second welded portion 15c on the base end side thereof is formed in a substantially boat-shaped cross section. When the opening portion of the bag-shaped member 20 is covered with the flow path cylindrical portion 15 and welded to the second welded portion 15c, the gap G is formed between the outer peripheral surface of the flow path cylindrical portion 15 and the side edges 20a and 20b of the bag-shaped member. (This gap G constitutes a cavity to be described later).

  A taper 15e that gradually decreases in diameter toward the protruding side may be formed in the tip opening 15b of the flow path cylinder portion 15. By forming such a taper 15e, it becomes easy to cover the bag-like member 20 on which three sides are welded, and the manufacturing cost can be reduced. In this case, the container 2 and the bag-like member are formed by forming the upper surface portion 11a of the main body portion 11 of the spout 10 in a flange shape so as to partition the first welded portion 12 and the second welded portion 15c. 20 welding processes are facilitated. Furthermore, the bag-like member 20 can be made of the same material as the sheet-like members 2a and 2b.

  When the bag-like member 20 is welded to the flow path cylinder portion 15 of the spout 10 as described above, a predetermined range above the tip opening 15b and the outer periphery of the flow path cylinder portion 15 are contained therein. A gap G existing between the surface and the side edges 20a, 20b of the bag-like member is a non-contact region (hollow portion; region R shown in white in the drawing). Such a non-contact region (hollow part) R has a bulge (thickness in a direction orthogonal to the bag-like member 20) in the flow path cylinder part 15, and a welding projection piece 15d in the second welding part 15c. As a result, the inner surface of the bag-shaped member 20 is not in close contact with each other (hollow portion). The upper side of the cavity R is in close contact with each other by a tensile force due to welding of the side edges 20a and 20b and the bottom edge 20c of the bag-like member 20, and a close contact portion R1 (a portion indicated by hatching). Will come to form. Further, a break line 20f is formed on the front end side of the bag-like member 20 so as to cross the close contact portion R1.

  The size of the hollow portion R can be variously modified depending on the protruding length of the flow channel portion 15, its diameter and shape, the material constituting the bag-like member, the thickness, and the like. Further, the length of the bag-like member 20 that covers the flow path cylinder portion 15 can be appropriately changed, and the sealing effect (outside air blocking effect) described later is the length of the contact portion R1 of the bag-like member 20. Therefore, the seal shape of the bag-like member 20 may be a straight line, and there is no need to provide a deformed portion or a bent portion.

  According to the spout-equipped container 1 having the above-described structure, the cut-off line 20f is cut, and then the container 50 is pressed by pressing the container 2 to increase the internal pressure of the container S, as shown in FIG. It becomes possible to pour out through the bag-like member 20 that is welded over the channel cylinder 15 of the spout 10. In this case, as described above, the bag-like member 20 has a cavity portion (non-contact portion portion where the inner surfaces are not in close contact) R and a contact portion (inner surfaces are in close contact with each other by a tensile force) in the vicinity of the tip opening 15b. The portion R1 is formed, and the container 2 is pressed so as to increase the internal pressure, so that the container moves so as to expand the contact portion R1 from the cavity portion R and is cut as shown in FIG. It will be poured out from the part. Further, by changing the pressing force, the discharge width W at the contact portion R1 can be automatically changed according to the pressing force.

  At the time of the above-described dispensing operation, as shown in FIG. 6, the bag-like member 20 can be easily inserted into the opening 60a of the bottle 60, which is another container. It can be easily performed.

  Then, when the pressing force of the container 2 is released after the operation of pouring the container, the container is stored as it is in the cavity R of the bag-like member 20, and the contact portion R1 ahead of it is pulled. The power recovers and comes into close contact again. In this case, the tightly sealed portion R1 is in a state in which a sealed film of the contained material is formed by the capillary force, and the outside air is accommodated together with the accommodated material stored in the cavity portion R from the distal end opening 15b of the flow path cylinder portion 15. It reliably prevents entry into the body 2 and exhibits a sealing effect (outside air blocking effect). In particular, as shown in FIG. 3 (b), the cavity R has a peripheral region (the outer peripheral surface of the flow channel cylinder 15 and the side edge 20a of the bag-like member, from above the tip opening 15b. It is also formed in the gap G) 20b, and when the pressing force is released also in this part, the stored contents are stored, so that the sealing effect is reliably maintained. .

  Further, according to the spout-equipped container 1 configured as described above, the spout 10 is poured out with the first welded portion 12 that welds the container 2 that accommodates the accommodated material in the main body 11. It has a simple structure in which the flow path cylinder portion 15 having the second welded portion 15c for welding the bag-like member 20 is integrally formed, and is accommodated in the first welded portion 12 of the spout 10 thus integrally formed. Since the body 2 is welded and the bag-like member 20 is welded to the second welded portion 15c, it is possible to easily manufacture a container having a sealing function. In particular, by attaching the spout 10 for pouring out the contents, it is possible to prevent the ejection hindrance caused by the film blockage when pouring out the contents. Furthermore, even if the bag-like member 20 described above uses the same material as the sheet-like members 2a and 2b constituting the container 2, it is possible to form the above-described cavity and contact portion, and the processing cost Can be reduced.

  Next, another embodiment of the spouted container according to the present invention will be described. In the embodiments described below, the same components as those in the above-described embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

FIG. 7: is a figure which shows 2nd Embodiment of the container with a spout concerning this invention.
In this embodiment, the opening / closing cap 70 is attached to the main body 11 of the spout 10 so that the bag-like member 20 can be accommodated.

  Specifically, a mounting portion (male screw portion) 17 is formed in the main body portion 11 so as to be coaxial with the flow path cylinder portion 15, and a female screw portion 70 a of the opening / closing cap 70 is screwed into this portion. By combining, the opening / closing cap 70 can be opened and closed. In this case, the opening / closing cap 70 can accommodate and mount the bag-like member 20, and by providing such an opening / closing cap 70, in the case where the entire contents 50 are not poured out, By storing the bag-shaped member 20 in the opening / closing cap 70 and attaching the opening / closing cap 70 to the male screw portion 17 formed in the main body portion 11, it is possible to improve hygiene and improve storage management. become.

FIG. 8 is a diagram showing a third embodiment of the spouted container according to the present invention.
In this embodiment, an opening / closing cap 80 having an opening shape similar to the shape of the flange portion can be attached to and detached from the main body portion 11 of the spout 10. In this case, a plurality of locking portions (projections) 18 are formed on the side edge of the flange portion of the main body portion 11, and the concave portion 80 a formed on the inner surface of the opening of the opening / closing cap 80 is engaged / disengaged at this portion. The opening / closing cap 80 is detachable.

  Thus, the configuration of the opening / closing cap that accommodates the bag-like member 20 can be modified as appropriate, and the attachment / detachment structure of the spout 10 with respect to the main body 11 can be modified as appropriate.

  FIGS. 9-12 is a figure which shows 4th Embodiment of the container with a spout which concerns on this invention, FIG. 9 is a figure which expands and shows a spout part, FIG. 10 is AA of FIG. FIG. 11 is a cross-sectional view taken along the line, FIG. 11 is a diagram showing the state of the contained article being poured out, a front view in which the spout portion is enlarged, and FIG. It is the side view which expanded the part.

  This embodiment is characterized in that an opening 15m is formed on the outer peripheral surface of the flow path cylinder portion 15 to allow the contents to flow out from the extraction flow path 15a. In this case, the inner surface of the bag-shaped member 20 comes into close contact with the outer peripheral surface of the flow path cylinder portion 15 by welding the inner surface on the opening side of the bag-shaped member 20 to the second welded portion 15c. The opening 15m is formed in a region where the inner surface of the bag-like member 20 is in close contact. Specifically, the opening 15m in the present embodiment is formed on the direction Y orthogonal to the line X connecting the side edges 20a and 20b that are the welded portions of the bag-like member 20, and is also the most in this direction. It is formed at a position where the distance becomes long (in this position, the inner surface of the bag-like member 20 is in close contact with the outer peripheral surface of the flow path cylinder portion 15 with the strongest force), as shown in the figure, facing each other in this direction. It is formed at two locations.

  Further, in the present embodiment, the projecting end of the flow path cylinder portion 15 is closed and bulged and formed in a cone shape (a conical portion 15h is formed on the projecting side), and the spout main body portion. 11 is finally poured out from the two openings 15m via the pouring channel 15a of the channel cylinder portion 15.

  According to the spouted container of the present embodiment, the container is pressed through the opening 15m as shown by the arrows in FIGS. 11 and 12 by pressing the container 2 to increase the internal pressure of the container S. The bag-like member 20 in the close contact state can be spread and poured out through the cavity R and the close contact portion R1 as in the above-described embodiment.

  Then, when the pressing force of the container 2 is released after the operation of pouring the container, the container is stored as it is in the cavity R of the bag-like member 20 as in the above-described embodiment. The close contact portion R1 comes into close contact again after the tensile force is recovered. Further, the portion where the opening 15m of the flow path cylinder portion 15 is formed is caused by the negative pressure on the container side and the tensile force by the side edges 20a and 20b (the tensile force acting on the outer peripheral surface of the flow path cylinder portion 15). The inner surface of the bag-like member 20 comes into close contact again, and the opening 15m is sealed. As a result, the contents stored in the cavity R are prevented from flowing back to the flow path 14, and a constant amount of the contents are always held in the cavity R, so that the outside air is blocked. Further, it becomes possible to further improve the airtightness. In addition, since the opening 15m of this embodiment is formed in the outer peripheral surface of the flow path cylinder part 15 in the position where the tensile force of the bag-like member 20 becomes the largest, the adhesion force of the bag-like member 20 is high, A high sealing effect can be exhibited.

  Further, in the present embodiment, as described above, the projecting end of the flow channel cylinder portion 15 is closed to form the conical portion 15h, so that it is possible to reliably prevent outside air from flowing into the accommodating portion side, and further, the conical portion As a result, the bag-shaped member 20 can be easily covered with the flow path cylinder portion 15 and can be manufactured easily.

  In the present embodiment, the position of the opening 15m formed in the above-described flow path cylinder portion 15 and the number of openings formed can be appropriately changed.

As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously.
The spout 10 configured as described above can appropriately change its attachment position in accordance with the shape of the container. Moreover, the flow path cylinder part 15 integrally formed with the main-body part 11 can change suitably about the cross-sectional shape and protrusion amount. In this case, the specific contact force of the contact portion R1 of the bag-like member 20 can be changed by the length and diameter of the flow path cylinder portion 15, but the storage object 50 is stored in the storage portion S. When the internal pressure is increased by applying a pressing force (pressing the storage portion S by hand), a flow path through which the stored matter 50 flows out is generated, and the internal pressure of the storage portion S is reduced by releasing the pressing force. Furthermore, it is only necessary to set so that the tensile force can be recovered, the inner surfaces of the bag-like members can be brought into close contact with each other, and the outside air can be prevented from flowing into the housing portion.
