JP5203260B2 - Extractor used for refilling contents - Google Patents

Description

  The present invention relates to a pouring tool used for refilling the contents, and more specifically, provided in a bag-like container filled with the contents for refilling, and the hinge cap in the container with the hinge cap. It is related with the extraction tool used in order to fill the content for refill in a bag-shaped container through the extraction opening currently formed in this.

  Shampoos, rinses, liquid detergents, and the like are marketed and filled in containers such as PET bottles. In recent years, in order to sell such container contents as cheaply as possible, they are often filled in a bag-like container (pouch) that is cheaper than a bottle and supplied to the market as a refill. That is, generally, when a consumer uses up the contents filled in the bottle, the contents filled in the pouch are refilled into a bottle for use.

  On the other hand, a bag-like container is formed into a bag shape by laminating a plastic film or aluminum foil, and conventionally, an opening is formed by tearing the end of the bag, and the contents are taken out through this opening. Recently, such a bag-like container has been used with a plastic pouring tool (generally called a spout) made of a cylindrical body that is open at both ends. It has come to be. In particular, in a bag-like container filled with the above-mentioned refill contents, such a pouring tool is attached in order to transfer the filled contents into a bottle. For example, Patent Document 1 proposes a pouch container filled with the above-mentioned refill contents.

JP 2004-231217 A

  By the way, the pouch container proposed in Patent Document 1 is based on the premise that the contents are refilled in a bottle equipped with a screw cap in which an upper lid is detachably provided by screw engagement. The container in which the screw cap is mounted can be easily refilled with the contents of the pouch container.

  However, as caps provided on containers such as bottles, not only screw caps but also many hinge caps whose upper lid is hinged to the cap body are used, especially seasoning liquids such as soy sauce and vinegar. In the containers that are used, hinge caps are frequently used. In order to refill the contents of the container provided with such a hinge cap, the pouch container proposed in Patent Document 1 has many points to be improved.

  That is, in both the screw cap and the hinge cap, a dispensing guide tube for stably pouring the contents in the bottle is formed around the dispensing opening formed in the cap body. Therefore, in any cap, the contents filled in the pouch container are refilled by inserting an extraction tool of the pouch container (bag-shaped container) into such an extraction guide tube. However, the screw cap and the hinge cap are different in the form of the dispensing cylinder.

  For example, in the screw cap, when the contents are poured out, the top lid is removed from the cap body, so the contents can be poured out from any position of the dispensing guide tube, Since the dispensing tube does not get in the way when the upper lid is closed, the upper end of the dispensing guide tube is entirely on the same plane (ie, no step is formed on the upper end) and a symmetrical ring shape have. For this reason, it is easy to stably hold the cylindrical-shaped dispensing tool inserted into the dispensing guide tube, and the looseness of the dispensing tool is not a problem when filling the contents from the pouch container. Therefore, the contents can be smoothly filled from the pouch container.

  However, in the hinge cap, the content is poured out from the portion opposite to the portion where the upper lid is hinged, so that the upper end of the dispensing guide tube is outward in a trumpet shape at this portion. Has an expanded shape. In addition, the hinge connecting part side of the dispensing guide tube is notched and has a low profile so that the dispensing guide tube does not get in the way when the hinged upper lid is turned and closed. It has become. As described above, the guide tube for pouring out the hinge cap has a step formed at the upper end portion thereof, and has an asymmetric shape in which a part of the upper end spreads in a trumpet shape. Therefore, when the contents are refilled, the pouring tool inserted inside the pouring guide tube is held in an extremely unstable state, and the contents in the pouch container are placed in the container in which the hinge cap is attached. When refilling, the pouring tool rattles, making it difficult to easily perform the refilling operation. That is, the refilling of the contents is performed by holding the easily deformed pouch container in an inverted state, so that if the pouring tool inserted into the pouring guide tube is unstable, the contents may be spilled. This is because troubles such as endeavors are likely to occur.

  Accordingly, an object of the present invention is a pouring tool provided in a bag-like container filled with a refill content, and when the refill content is filled in a container with a hinge cap, the hinge cap It is an object of the present invention to provide a pouring tool that can be stably held without rattling when inserted into the pouring guide tube.

According to the present invention, the cylindrical side wall is adhesively fixed to the bag-like container filled with the refill content, and the refill content in the bag-like container is lowered from the top plate portion and the peripheral edge of the top plate portion. A pouring guide extending upward from the top plate portion so as to surround the pouring port and the pouring port in the top plate portion. A tube is formed, a notch portion is formed on the hinge connecting portion side of the dispensing guide tube, and a hinge cap in which both ends of the notch portion are stepped portions is fitted and fixed. In an extraction tool for injecting into a container with a hinge cap through the hinge cap,
The pouring tool extends downward from the lower surface of the plate-like substrate, the support member to which the bag-like container is bonded and fixed to the outer surface, and extends upward from the upper surface of the plate-like substrate. A cylindrical space for refilling the contents for refilling extending through the plate-like substrate is formed inside the support member and the dispensing cylinder.
A sealing member is formed at the upper end of the dispensing tube via a breakable score, and the upper end of the cylindrical space is closed by the sealing member, and the sealing member has a score rupture. There are knobs for
Three or more locking ribs extend radially outward from the outer surface of the dispensing tube at intervals in the circumferential direction, and the three or more locking ribs are positioned on the same surface. The lengths of these locking ribs are such that the diameter of the imaginary circle formed by the tips of the ribs is approximately the same as the inner diameter of the base portion of the guide tube for pouring the hinge cap. An extraction tool is provided, which is characterized in that it is set to be.

  In the pouring tool according to the present invention, the circumferential edge of the plate-like substrate is notched formed on the hinge connecting portion side of the pouring guide tube of the hinge cap at a circumferential interval. It is preferable that two stopper protrusions that can engage with the stepped portion of the portion extend radially outward.

  The pouring tool of the present invention is attached to a bag-like container filled with the contents for refilling, and is used for filling the contents for refilling in the bag-like container into a container with a hinge cap. However, a particularly important feature is that three or more locking ribs extend radially outward from the outer surface of the extraction tube extending upward from the upper surface of the plate-like substrate. These locking ribs are formed so as to be positioned on the same plane, and the length of these locking ribs is such that the diameter of the virtual circle formed by the tip of the rib is formed in the hinge cap. It is in the point set to the substantially the same magnitude | size as the internal diameter of the base part of the guide tube for extraction currently performed.

  In other words, the refilling of the contents from the bag-shaped container to the container with the hinge cap is carried out by inserting the pouring tube of the pouring tool into the pouring guide tube of the hinge cap and inverting the bag-shaped container in this state. Alternatively, it is performed by tilting to a state close to that. However, since the above-described locking rib is formed on the outer surface of the dispensing cylinder, the locking rib on the outer surface of the dispensing cylinder is inserted into the dispensing guide cylinder. The front end is held in a state of being in close contact or close to close contact with the inner surface of the base portion of the dispensing guide tube. For this reason, the extraction cylinder is stably held in the state of being inserted into the extraction guide cylinder, and is not affected at all by the shape of the upper end of the extraction cylinder of the hinge cap, for example. Linear movement in the horizontal plane (surface perpendicular to the dispensing cylinder) of the dispensing cylinder inserted into the cylinder is effectively suppressed. For this reason, even when the bag-like container is inverted with the dispensing cylinder of the dispensing tool inserted into the dispensing guide cylinder of the hinge cap, the rattling of the dispensing tool (the dispensing cylinder) is effective. In addition, even when the bag-like container is held in an inverted state, there is no rattling of the pouring tool (pouring cylinder) and it is held stably. The refilling operation can be performed smoothly without causing any inconvenience.

  Further, in the pouring tool of the present invention, when two stopper protrusions extending radially outward are provided on the circumferential edge of the plate-like substrate at intervals in the circumferential direction, the stopper protrusions Can be engaged with the stepped portion formed by the notch formed on the hinge connecting portion side of the guide tube for extraction of the hinge cap, so that the rotation of the extraction tube inserted in the guide tube for extraction The movement can be effectively suppressed, and this dispensing cylinder is held more stably, and it is possible to more effectively prevent rattling of the dispensing tool (pouring cylinder) during the refilling operation of the contents. The refilling operation becomes easier.

<Hinge cap structure>
Prior to explaining the structure of the pouring tool of the present invention, the outline of the hinge cap attached to the mouth of the bottle to be refilled with the contents filled in the bag-like container (pouch) provided with the pouring tool. The structure will be described.

  Referring to FIGS. 1 and 2 showing the hinge cap, the hinge cap generally indicated by 1 includes a cap body 3 and an upper lid 5 hinged to the cap body 3.

  The cap body 3 is composed of a top plate portion 7 and a cylindrical side wall 9 that descends from the periphery of the top plate portion 7. As shown in FIG. 1, the cap body 3 is attached to the mouth portion Z of the bottle. The fitting is fixed.

  An inner ring 10 extending downward from the cylindrical side wall 9 is formed on the inner surface of the top plate portion 7, and a bottle opening is formed in a space between the inner ring 10 and the cylindrical side wall 9. The portion Z is fitted, whereby the cap body 3 is firmly fixed to the bottle mouth portion Z.

  In addition, a spout 11 formed by tearing by a score or the like is formed in the central portion of the top plate portion 7, and the content liquid filled in the bottle is poured out through the spout 11. In addition, the content liquid is refilled and filled into the bottle.

On the upper surface of the top plate portion 7 as described above, a guide tube 13 for pouring is erected so as to surround the spout 11, and the content liquid poured out from the spout 11 is the guide tube 13 for pouring. It is discharged along the inner surface.
Further, a short locking projection 15 is formed on the outer side of the dispensing guide tube 13 so as to stabilize the closed upper lid 5 when the upper lid 5 is closed. Can be retained.

  An upper lid 5 is hinged to the upper end portion of the cylindrical side wall 9 of the cap body 3. This hinge connection portion is indicated by 17, a main band 17 a connected to the upper end of the cylindrical side wall 9, and an auxiliary band 17 b located on both sides and connected to a portion slightly lower than the main band 17 a, 17b. When the upper lid 5 is hinged using these bands 17a and 17b, when the closed upper lid 5 is pivoted and opened largely, the opened state is stably maintained.

  Further, the cylindrical side wall 9 is divided into an inner side wall and an outer side wall by a slit 19 extending downward from above, and the inner side wall and the outer side wall are formed at the lower end portion as is apparent from FIG. It is connected. By providing such a slit 19 and dividing the cylindrical side wall 9 into an inner side wall and an outer side wall, the cap body 3 can be easily detached from the bottle mouth Z, and the hinge cap 1 is separated from the bottle. It becomes possible to discard easily. For example, the upper lid 5 is hinged to the upper end portion of the outer side wall of the cylindrical side wall 9, but as shown in FIG. 2, at both side portions of the hinge connecting portion 17, In the state where the axial scores 20 and 20 are formed and the upper lid 5 is opened, the upper lid 5 (hinge connecting portion 17) is pulled downward, whereby the scores 20 and 20 are broken and then the upper lid 5 is broken. By pulling upward, the inner wall is removed while breaking the axial score (not shown) extending upward from the lower end provided on the inner wall at a position facing the axial score 20, 20 of the outer wall. The cap body 3 can be easily removed from the bottle mouth portion Z by lifting up.

  Further, the upper lid 5 hinged to the cap body 3 is composed of a top plate portion 21 and a skirt 23, and the lower end portion of the skirt 23 is hinged to the upper end portion of the cylindrical side wall 9 (outer wall). Has been.

  A seal ring 25 is formed on the inner surface of the top plate portion 21. When the upper lid 5 is closed, the seal ring 25 is in close contact with the inner surface of the above-described guide tube 13 for pouring, thereby ensuring sealing performance. It has come to be. In addition, an arc-shaped protrusion 27 that is slightly longer than the seal ring 25 is provided on a portion of the inner surface of the top plate portion 21 on the hinge connecting portion 7 side, thereby preventing score breakage of the hinge cap. That is, in an unopened state in which the hinge cap 1 is attached to the container mouth portion Z, a sealing wall (not shown) capable of closing and removing the spout 11 is connected to the top plate portion 7 by an endless score (not shown). However, when a pressing force is accidentally applied from above with the upper lid 5 closed, the arc 27 contacts the upper surface of the top plate portion 7 of the cap body 3, thereby lowering the seal ring 25 of the upper lid 5. Therefore, the endless score can be effectively prevented from being broken by the seal ring 25.

  Further, a flange 29 is formed at the lower end of the skirt 23 on the side opposite to the hinge connecting portion 7, and the upper lid 5 can be easily turned in the opening direction or the closing direction with the flange 29. Can be done. Further, as shown in FIG. 1, a recess 30 is formed on the inner surface of the lower portion of the skirt 23 in a circumferential shape. That is, when the upper lid 5 is closed, the concave portion 30 engages with the locking projection 15 of the cap body 3, whereby the closed state of the upper lid 5 is stably maintained.

  In the hinge cap 1 as described above, the extraction guide tube 13 provided on the cap body 3 is formed so that the region opposite to the hinge connecting portion 17 is tall (the tall portion is 13a). On the other hand, the region on the hinge connecting portion 17 side is notched and short (the short portion is indicated by 13b), and therefore the tall portion 13a and the back portion are formed. A step portion 13c is formed between the lower portion 13b.

  That is, when the entire guide tube 13 for pouring is formed tall, when the upper lid 5 is turned and closed, the seal ring 25 is located at the upper end of the guide tube 13 for pouring in the region on the hinge connecting portion 7 side. It hits the part, and the turning of the upper lid 5 in the closing direction is obstructed, and the upper lid 5 cannot be closed. Moreover, when the whole guide tube 13 for pouring is formed short, the original function of the guide tube 13 for pouring (function to guide the content liquid poured out from the spout 11) will be impaired. . Accordingly, when the upper lid 5 is opened and the content liquid is poured out, the pouring guide tube 13 is made tall in a region opposite to the hinge connecting portion 17 where the upper lid 5 does not get in the way, and the content liquid is poured out. In the region on the side of the hinge connecting portion 17 where no removal is performed, the guide tube 13 for pouring is lowered.

  In addition, in the tall part 13a of the guide tube 13 for pouring, since the content liquid is poured out from the spout 11, the poured content liquid is smoothly discharged without dripping down. Thus, the upper end part has a shape that is curved outward in a trumpet shape.

<Structure of the dispensing tool>
The pouring tool of the present invention is provided in a bag-like container (hereinafter referred to as a pouch) filled with a refilling content liquid into a hinge cap-equipped container in which the hinge cap 1 is mounted. The pouring tool is inserted into the pouring guide tube 13 of the hinge cap 1 so that the content liquid in the pouch is refilled into the hinge cap-equipped container.

  The structure of such a pouring tool is shown in FIGS. FIG. 3 is a perspective view of the pouring tool, and FIGS. 4 and 5 are a top view and a bottom view of the pouring tool, respectively. Moreover, FIG. 6 is a figure which shows each side surface of this extraction tool, FIG. 6 (a) is a front side view, FIG.6 (b) is a right view, FIG.6 (c) is a rear view. Further, FIG. 7 is a side sectional view showing an AA section in the top view of FIG.

  3 to 7, a pouring tool of the present invention indicated by 50 as a whole extends downward from the lower surface of the plate-like substrate 51 and the plate-like substrate 51, and forms a film or foil (for example, a pouch). 7 is provided with a support member 53 to which various thermoplastic resin films, resin-coated aluminum foil, etc.) are bonded and fixed, and a dispensing cylinder 55 extending upward from the upper surface of the plate-like substrate 51. As shown in FIG. 5, cylindrical spaces 57 and 59 communicating with each other are formed in the support member 53 and the inside of the dispensing cylinder 55, respectively. The refilling content liquid filled in the pouch is discharged via the, and can be refilled and filled in the container provided with the hinge cap 1 described above.

  In the pouring tool 50 described above, the plate-like substrate 51 has a disk shape having an outer shape substantially the same as the inner diameter of the upper end of the pouring guide tube 13 of the hinge cap 1 described above. Two stopper projections 60, 60 are formed on the circumferential edge of the plate-like substrate 51 at intervals in the circumferential direction. The function of the stopper protrusion 60 will be described later.

  As can be understood from the perspective view of FIG. 3 and the bottom view of FIG. 5, the support member 53 has a boat-like shape as a whole, and a central portion is a cylindrical trunk portion 53 a. A strip-shaped flange piece 53b whose thickness gradually decreases from the portion 53a toward the peripheral portion is formed, and the outer surface of the support member 53 has a smooth curvature surface from the cylindrical body portion 53a to the flange piece 53b. Therefore, a clear boundary line is not formed between the cylindrical body portion 53a and the flange piece 53b. As can be understood from the side sectional view of FIG. 7, the cylindrical space 57 of the support member 53 is formed in the cylindrical body portion 53a. Further, holes 61 and 61 are formed in the support member 53 so as to be spaced apart from the cylindrical space 57 from the lower end thereof upward (see FIGS. 7 and 5). . The holes 61 and 61 are formed to prevent sink marks at the time of molding. If the holes 61 and 61 are not formed, sink marks are generated at the time of molding, and the outer surface becomes a disordered surface. This is because poor welding between the support member 53 and the pouch occurs.

  In addition, a plurality of protruding pieces 63 are formed on the outer surface of the support member 53 as described above at intervals in the axial direction (three protruding pieces 63 are formed in the example in the figure). The side surface of the projecting piece 63 is a flat surface, and as can be understood from each side view of FIG. 6, the projecting piece 63 does not extend to the peripheral portion of the flange piece 53b. The outer surface of the peripheral portion of the flange piece 53b is a flat surface 53c with no step. That is, a film or foil forming a pouch is bonded and fixed to the side surface of the overhanging piece 63 and the flat surface 53c of the peripheral edge portion of the flange piece 53b by heat welding so as to surround the entire circumference of the support member 53. Thus, the pouring tool 50 is firmly fixed to the pouch, and the content liquid in the pouch can be discharged through the cylindrical spaces 57 and 59.

  On the other hand, a sealing wall 65 is formed at the upper end of the dispensing cylinder 55 provided on the upper surface of the plate-like substrate 51 so as to close the cylindrical space 59. The sealing wall 65 has a breakable score 67. It connects with the upper end of the extraction | pipe cylinder 55 via (refer FIG. 7). Such a sealing wall 65 ensures the sealing performance of the pouch with the pouring tool 50 attached.

  Further, a large knob 69 is provided on the upper surface of the seal wall 65. By pushing down the knob 69, a part of the score 67 is broken, and the knob 69 is further pulled. The seal wall 65 is removed from the dispensing cylinder 55 by tearing the score 67 over the entire circumference or by twisting while gripping the knob 69, thereby opening the cylindrical space 59 and the contents in the pouch. The liquid can be discharged.

  With reference to FIG. 8 and FIG. 9 for explaining the refilling operation of the pouch content liquid using the above-described pouring tool 50, the pouring tool 50 provided in the pouch 100 has the seal wall 65 removed. The dispensing tube 55 is inserted into the dispensing guide tube 13 of the hinge cap 1 attached to the bottle mouth Z and the upper lid 5 is opened, and the upper end portion of the dispensing tube 55 is attached to the hinge cap 1. This is done by intruding into the bottle mouth Z through the formed spout 11 and inverting the pouch 100 in this state.

With reference to FIGS. 8 and 9 in addition to FIGS. 3 to 7, in the pouring tool 50 of the present invention used as described above, the outer surface of the pouring tube 55 has four pieces. A locking rib 70 is provided. The locking ribs 70 are formed in the same plane, and when the dispensing tube 55 is inserted into the dispensing guide tube 13 of the hinge cap 1 when the content liquid is refilled, four locking ribs 70 are formed. All of the ribs 70 are located at or near the base of the dispensing guide tube 13 (see particularly FIG. 8).
8 is a view seen from above, and the portion of the extraction tool 70 hidden by the support substrate 51, the outlet 11 of the hinge cap 1, and the like are indicated by dotted lines.

  Further, as shown in FIG. 9, the length of these locking ribs 70 is such that the diameter of the virtual circle X formed by the tip of the rib 70 is the root of the guide tube 13 for pouring of the hinge cap 1. Is set to be approximately the same size as the inner diameter, for example, the inner diameter of the attachment portion is about ± 0.2 mm. That is, by forming the locking rib 70 as described above, when the dispensing cylinder 55 is inserted into the dispensing guide cylinder 13 of the hinge cap 1 as shown in FIG. The linear movement in the horizontal plane 55 (in a plane substantially perpendicular to the dispensing guide tube 13) is effectively limited, and as a result, rattling and the like are suppressed and the dispensing tube 55 is stabilized. Can be held. Accordingly, for example, the pouch 100 is turned upside down with the dispensing cylinder 55 inserted, and the refilling and filling of the content liquid from the inverted pouch 100 into the bottle is performed smoothly without causing any inconvenience. Is possible.

In the example shown in the figure, the four locking ribs 70 are formed at intervals of 90 degrees, but this number may be at least three. That is, when the number of the locking ribs 70 is two, there is a direction in which the inserted extraction tube 55 can move linearly in the horizontal plane. This is because if it is formed at equal intervals, the linear movement of the dispensing tube 55 is restricted in all directions within the horizontal plane. However, even if the number of the locking ribs 70 is increased more than necessary, the cost is only increased due to an increase in the amount of resin and so on. The rib 70 is preferably provided, and in particular, two in the same direction and perpendicular to the direction in which the flange piece 53b of the support member 53 extends and the direction in which the knob piece 69 extends as in this embodiment. In consideration of die cutting during injection molding, it is the best mode to provide four at 90 ° equidistant intervals.
It is good.

  In the pouring tool 50 of the present invention, the plate-like substrate 51 has a disk shape having an outer shape substantially the same as the inner diameter of the upper end of the pouring guide tube 13 of the hinge cap 1. When 55 is inserted into the dispensing guide tube 13, the plate-like substrate 51 is positioned or abutted on the upper end portion of the dispensing guide tube 13 or in the vicinity thereof. As described above, two stopper projections 60 and 60 are formed on the circumferential edge of the plate-like substrate 51 at intervals in the circumferential direction. By providing, the rotation of the dispensing cylinder 55 inserted into the dispensing guide cylinder 13 can be effectively limited, and the dispensing cylinder 55 can be held more stably during the refilling operation of the content liquid. Can do.

  That is, the distance between the two stopper protrusions 60 and 60 is set to be approximately equal to the circumferential length of the lower portion 13 b of the guide tube 13 for pouring of the hinge cap 1. Therefore, when the dispensing tube 55 is inserted into the dispensing guide tube 13 and appropriately rotated, the portion between the two stopper projections 60, 60 is the lower portion 13b of the dispensing guide tube 13. Accordingly, the further rotation of the dispensing cylinder 55 is such that the stopper projection 60 engages with the stepped portion 13c of the dispensing guide cylinder 13 regardless of the direction of rotation. Limited by.

  Thus, in the pouring tool 50 of the present invention described above, the pouring tube 55 is inserted into the pouring guide tube 13 having a shape unique to the hinge cap 1 in which the stepped portion 13c and the like are formed at the upper end. Although the refilling operation is performed, the insertion state of the dispensing cylinder 55 is stably maintained, its linear movement and rotational movement are effectively limited, and rattling is effectively suppressed. The liquid refilling operation can be performed easily and smoothly without causing inconvenience such as leakage of the content liquid. In particular, when refilling a high-viscosity content liquid, an operation such as holding the pouch 100 in an inverted state and squeezing the pouch 100 is performed. Since the outlet cylinder 55 is stably held in the inserted state, such a refilling operation of the high-viscosity content liquid can be easily performed.

  In addition, although the extraction tool 50 of the present invention described above is formed by injection molding using various thermoplastic resins that can be thermally bonded, generally, it is bonded to a film or foil forming the pouch 100. Various olefin resins such as low-, medium-, or high-density polyethylene, linear low-density polyethylene, isotactic polypropylene, syndiotactic polypropylene, poly 1-butene, poly Random or block copolymers of 4-methyl-1-pentene or α-olefins such as ethylene, propylene, 1-butene, 4-methyl-1-pentene, ethylene-vinyl acetate copolymer, ethylene- (meth) Acrylic acid copolymer, ethylene- (meth) acrylic acid ester copolymer, ion-crosslinked olefin copolymer Onomer) can be used. In addition, olefins and cyclic olefins (hydrocarbon compounds having a bicyclo [2,2,1] hept-2-ene skeleton such as norbornene and tetracyclododecene) are preferred because of their good barrier properties against water vapor and the like. The pouring tool 50 may be formed by combining. Furthermore, it may be formed using a polyester resin such as polyethylene terephthalate (PET) or polyethylene naphthalate (PEN).
