Description

  The present invention relates to a refilling method for refilling a liquid material from a refill container into a main container that contains a liquid material such as skin lotion or emulsion.

  In order to save the resources and reduce the price of the product, the contents of the container containing liquids such as skin lotion and emulsion are refilled from the refill container into the container so that the container can be used repeatedly. Has been done.

  As the refill container, generally a thin bottle by pouch or blow molding is used. At the time of refilling, the contents are transferred to the main container by holding the refill container so that the outlet of the refill container is positioned above the mouth of the main container and gradually increasing the inclination of the refill container. .

  However, when the refill container is a pouch, the refill container itself is not stretched and its outer shape changes as the contents are discharged, so that the contents discharged from the pouch do not come off the mouth of the container. Therefore, considerable care is required for gripping the pouch, which is complicated. There is also a problem that the spout is closed carelessly due to the overlap of the films constituting the pouch. The bottle is easier to hold the container when refilling than a pouch, but because the air replacement is not performed smoothly, the contents may be discharged in a pulsating manner, which causes the contents to foam unnecessarily Cause problems.

  As a method for stabilizing the discharge of the contents from the refill container, it has been proposed to provide an air replacement path at the spout of the refill container (Patent Document 1).

  Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  FIG. 1A is a perspective view of a main container 10 and a refill container 40A of an embodiment used in the refill method of the present invention. The main container 10 includes a main container body 11 for storing the liquid material A and a lid portion 20A.

  The container body 11 has a bottomed cylindrical shape and is self-supporting, and has a mouth portion 12 upward. As shown in FIG. 1B (a), the peripheral wall of the mouth portion 12 is reduced in outer diameter in two steps toward the upper end portion, and a screw is formed on each of the thin peripheral wall upper portion 13 and the large diameter peripheral wall lower portion 14. Has been.

  The lid portion 20A closes the mouth portion 12 of the container body 11 so as to be freely opened and closed, and more specifically includes an inner lid 21A and an outer lid 30 as shown in FIG. The inner lid 21A has a substantially disk shape, has a small discharge hole 22 in the center, and has an annular wall 23 around it. As shown in FIG. 2B, the inner side of the annular wall 23 of the inner lid 21A and the peripheral wall upper portion 13 of the mouth portion 12 of the main container body 11 are detachably screwed together. As shown in FIG. 2C, in the state where the inner lid 21A is screwed with the peripheral wall upper portion 13 of the mouth portion 12 of the container main body 11, the outer lid 30 is formed from the outer side of the inner lid 21A to the lower portion of the peripheral wall of the mouth portion 12. 14 and screw.

  Generally, an inner lid having a small discharge hole that is attached to a container body containing a liquid material is fitted into the mouth of the container body by a driving method, so that it cannot be easily attached and detached. Although it is difficult to refill the main body with the liquid material, according to the main container 10, the inner lid 21A is detachably attached to the mouth portion 12 of the main container body 11 by screwing. When used as an object discharge container, the inner lid 21A can be screwed into the mouth portion 12 of the main body 11 to discharge an appropriate amount of the liquid material A from the small discharge hole 22, and the main body 11 is liquid. When filling the object A, it is easy to remove the inner lid 21A from the mouth part 12 and to fill the liquid substance A from the mouth part 12. Therefore, this container 10 is suitable for use in refilling the liquid material A.

  On the other hand, as shown in FIG. 1A (b), the refill container 40A has a bottomed cylindrical refill container body 41 and the top of the refill container body 41 outward from the center axis L1 of the refill container body 41. A projecting portion 42 for projecting a dispensing nozzle is provided. The refill container main body 41 is formed from a thin blow-formed bottle, and is a self-supporting container that maintains a constant shape regardless of the presence or absence of contents.

  The dispensing nozzle forming protrusion 42 stands up from a cap 43 formed integrally with the dispensing nozzle forming protrusion 42 and is fixed to the mouth of the refill container main body 41 by the cap 43 so as not to be detachable. Yes.

  The dispensing nozzle forming protrusion 42 is such that the tip of the cylindrical body 44 is closed by an easy-opening portion 45, and the central axis L2 of the cylindrical body 44 is the central axis L1 of the refill container body 41. Matches. 1D, the outer diameter of the base portion 44a of the tubular body 44 is slightly smaller than the opening diameter of the mouth portion 12 of the container body 11, and the tubular body 44 is connected to the mouth portion 12 of the container body 11. In addition, it is a size that can be inserted almost without wobbling. Further, the outer diameter of the cap 43 is slightly larger than the opening diameter of the mouth portion 12 of the container main body 11, and the cylindrical body 44 is fixed to the main body 44 by a horizontal surface 44b of a step portion provided between the cap 43 and the base portion 44a. The cap 43 can be supported by the mouth 12 when inserted into the mouth 12 of the container body 11, that is, the refill container body 41 can be supported in an inverted state on the container body 11.

  As shown in FIG. 4A, the easy-open portion 45 includes an annular fracture portion 46 formed on the cylindrical body 44 along a line to be fractured in order to obliquely cut the distal end portion of the cylindrical body 44, and an annular fracture portion. The ring-shaped finger-hanging portion 47 is provided on the side of the cylindrical body closer to the distal end portion of the cylindrical body 44 than 46. Here, as the degree of inclination with which the tip of the cylindrical body 44 is obliquely cut, an angle θ (FIG. 4A (FIG. 4A ( b)) is preferably set to 30 to 60 °.

  As a more specific form of forming the annular fracture portion 46, for example, an annular groove is formed in the cylindrical body 44, and the cylindrical body 44 is made thin at this groove portion. As a result, as shown in FIG. 4B, when the finger hooking portion 47 is pulled up in the direction of the arrow with the upper end portion of the annular breaking portion 46 as a fulcrum, the annular breaking portion 46 breaks and the easy-opening portion 45 can be easily removed. . In addition, as the cyclic | annular fracture | rupture part 46, the thin part which made the wall thickness of the cylindrical body thin from the front and back along the line which should be fracture | ruptured may be formed, and a half cut etc. may be formed. Moreover, as long as the easy-opening part 45 can be removed, the thin part, the half cut, etc. which form the cyclic | annular fracture | rupture part 46 can be formed continuously or intermittently.

  When the easy-opening portion 45 is removed, the dispensing nozzle forming protrusion 42 becomes the dispensing nozzle 48 whose tip is obliquely cut.

  Note that the cap 43 provided with the dispensing nozzle forming protrusion 42 can be molded separately from the refill container main body 41. In addition, the filling of the liquid material A into the refill container 40A at the time of manufacture is performed before the cap 43 is attached to the mouth of the refill container body 41 and fixed.

  In the refilling method of the present invention, as shown in FIG. 1B, first, the outer lid 30 and the inner lid 21 </ b> A are removed from the main container body 11 of the main container 10 to open the mouth 12. On the other hand, a finger is placed on the finger hooking portion 47 of the refilling container 40A and pulled up to remove the easy-opening portion 45 to obtain a refilling container 40A provided with a dispensing nozzle 48. Then, as shown in FIG. 1C, the dispensing nozzle 48 of the refill container 40A is inserted into the mouth portion 12 of the main container body 11, and as shown in FIG. 1D, the refill container main body 41 is placed on the main container body 11. In this state, the main body 11 and the refill container body 41 are self-supported and the liquid material A is refilled.

  At this time, the central axis L2 of the cylindrical body 44 and the central axis L1 of the refill container main body 41 coincide with each other, the refill container main body 41 stands vertically on the main container body 11, and the base 44a of the cylindrical body. The cylindrical body 44 is formed in such a size that the cylindrical body 44 does not fluctuate at the mouth part 12 of the container body 11, and the horizontal surface 44 b of the step part of the tubular body 44 is the upper edge of the mouth part 12 of the container body 11. Therefore, even if the refill container main body 41 is not gripped, the self-supporting state is maintained. Therefore, the trouble of gripping the refill container 40A can be greatly reduced so that the liquid material does not spill during refilling.

  Moreover, since the pouring nozzle 48 has an appropriate diameter and the tip is cut obliquely, the liquid A is suppressed from pulsation and is smoothly poured from the refill container body 41 to the main container body 11. . Therefore, unnecessary foaming of the liquid A can also be suppressed. For example, when the viscosity of the liquid A is 500 mPas to 10000 mPas, the inner diameter of the pouring nozzle 48 is set to 12 to 20 mm, and the angle θ of the oblique cutting of the pouring nozzle is set to 40 to 40. This is particularly noticeable when the angle is 50 °.

  The refilling method of the present invention can be applied to various main containers having an upward mouth portion. For example, the refilling method of the present invention can be suitably applied to the present container having the lid portion 20B shown in FIG. 3 instead of the lid portion 20A shown in FIG.

  As shown in FIG. 3 (a), the lid portion 20B is a disc-shaped inner lid having an annular member 24 fitted by fitting into the mouth portion 12 of the container body 11 and a discharge small hole 22 in the central portion. 21B and the outer lid 30. The annular member 24 and the inner lid 21 </ b> B are connected by a hinge 25. Therefore, the inner lid 21 </ b> B can cover the mouth portion 12 of the container body 11 so as to be freely opened and closed. As shown in FIG. 3C, the outer lid 30 is screwed into the mouth 12 of the main container body 11 from the outside of the inner lid 21 </ b> B with the inner lid 21 </ b> B covering the mouth 12 of the main container body 11. . Therefore, according to the container having the lid portion 20B, when used as a discharge container for the liquid A, the hinge 25 is closed and the opening of the container body 11 is closed by the inner lid 21B as shown in FIG. An appropriate amount of the liquid material A can be discharged from the discharge small hole 22 so as to cover the portion 12, and when filling the liquid material A into the container body 11, the hinge 25 is opened to open the mouth 12 of the container body 11. It is easy to fill the liquid material A from the mouth portion 12 with a large opening. Therefore, this container having the lid portion 20B is also suitable for refilling the contents.

  In addition, the lid member 20B may be formed by integrally forming the annular member 24, the inner lid 21B, and the hinge 25 connecting them, and the annular member 24 and the inner lid 21B molded separately are hinges 25. It may be connected with.

  The refilling method of the present invention can be carried out using various refilling containers having a self-supporting property, having a pouring nozzle whose tip is cut obliquely at the top of the refilling container body. Various refill containers provided with an easy-open portion so that a discharge nozzle is formed can be used.

  For example, in the refill container 40B shown in FIG. 5, the base portion 44a of the cylindrical body 44 that is cylindrical in the refill container 40A shown in FIG. 4A is formed into a rectangular tube shape with rounded corners on the side edges. Is. 1D, the refill container 40A is inverted on the main container body 11, and the liquid substance A is refilled so that the mouth portion 12 of the main container body 11 is covered with the refill container 40A. Since the outer peripheral surface of the base 44a of the cylindrical body 44 is only in contact with the inner wall of the mouth portion 12 of the main container body 11 at the side edge, it does not touch the inner wall of the mouth portion 12 in the entire peripheral surface. Can do. In addition, the refill container 40 </ b> A can be fixed to a certain extent on the main body 11 by bringing the side edge of the base 44 a of the cylindrical body 44 into contact with or close to the inner wall of the mouth 12 of the main body 11. The same effect can be obtained even if the cross-sectional shape of the base portion 44a of the cylindrical body 44 is an ellipse or a polygon with more corners.

  Further, in the refill container 40A shown in FIG. 4A, the refill container main body 41, the dispensing nozzle forming protrusion 42, and the cap 43 may be integrally formed. In that case, a separate opening is provided at the bottom of the refill container main body 41, the refill container main body is filled with the liquid material from the opening at the bottom, and after the filling, the bottom opening is sealed off by heat sealing or the like. That's fine.

  In the refill container of the present invention, the easy-open portion 45 is formed in the cylindrical body 44 so that the tip end portion of the cylindrical body 44 is obliquely cut like the refill container 40C shown in FIG. You may form from the cyclic | annular fracture | rupture part 46 and the ring-shaped finger-hook part 47 which stood up at the cylindrical body front end part side end surface 49 enclosed by the cyclic | annular fracture | rupture part 46. FIG. In the refill container 40C, as shown by an arrow in FIG. 6B, the ring break portion 46 is broken by pulling the finger hook portion 47 upward, and the easy-open portion 45 is removed as shown by a broken line.

  As in the refill container 40 </ b> D shown in FIG. 7, the ring-shaped finger hook portion 47 in the easy-open portion 45 is supported substantially horizontally on the cylindrical body distal end side end surface 49 surrounded by the annular fracture portion 46. As described above, the upper end portion of the cylindrical body distal end side end surface 49 and the finger hook portion 47 may be connected. In the refill container 40D, as shown by an arrow in FIG. 7B, by pulling the finger hook portion 47 obliquely downward, the annular fracture portion 46 is broken, and the easy-open portion 45 is removed as indicated by a broken line. The

  Like the refill container 40 </ b> E shown in FIG. 8, the ring surface of the ring-shaped finger hook portion 47 in the easy-open portion 45 is parallel to the standing direction of the cylindrical body 44 on the side surface side of the cylindrical body 44. The upper end portion of the cylindrical body distal end side end surface 49 and the upper end portion of the finger hook portion 47 may be connected via the belt-like connecting portion 50.

  In this case, it is preferable that the lower end portion of the ring-shaped finger-hanging portion 47 and the upper surface of the cap 43 are tied together with, for example, a twig-like securing portion 51a so that it can be easily separated by hand. As a result, it is possible to prevent the finger-hanging portion 47 from being bent around during the conveyance, etc., and being accidentally opened. Note that the position where the finger hooking portion 47 is locked is not limited to the upper surface of the cap 43, and for example, as shown in FIG. 8C, the locking portion 51b may be provided on the base 44a of the cylindrical body.

  As a method of using this refill container 40E, as shown in FIG. 8B or FIG. 8C, first, the connecting portion 51a or 51b between the finger hook portion 47 and the upper surface of the cap 43 is shredded, and the strip-like connecting portion 50 is used. The finger-hanging portion 47 is caused to be reversed as shown by a broken line (arrow a), and the finger-hanging portion 47 is further pulled down to the side opposite to the position where the original finger-hanging portion 47 is disposed (arrow b). Thereby, the cyclic | annular fracture | rupture part 46 fractures | ruptures and the easy-opening part 45 is removed as shown with a dashed-two dotted line. When the ring portion is reversed and caused in this way, a lever is applied to the upper end portion of the annular fracture portion 46 in the middle of the ring portion, so that a crack is generated, and the fracture spreads from there, so that opening is facilitated.

  Like the refill container 40F shown in FIG. 9A, the easy-opening portion 45 includes an annular fracture portion 46 formed in the cylindrical body 44 so that the tip end portion of the cylindrical body 44 is obliquely cut, and an annular fracture portion 46. You may form from the opening tab 53 extended from the cylindrical body front end part side end surface 49 enclosed by. According to this refill container 40F, as shown in FIG. 9B, by pulling up the opening tab 53, the easy-opening portion 45 is rotated with the lowest point of the annular breaking portion 46 facing the opening tab 53 as a fulcrum. A force can be applied so as to move, and the easy-open portion 45 can be easily removed.

  Further, as in the refill container 40G shown in FIG. 10A, the easy-open portion 45 includes an annular fracture portion 46 formed in the cylindrical body 44 so that the tip end portion of the cylindrical body 44 is obliquely cut, and an annular fracture. You may form from the knob | pick part 52 formed with the semi-disc-shaped curved plate-shaped member which stood up at the cylindrical body front end part side end surface 49 enclosed by the part 46. FIG. As shown in FIG. 10A (b), the cross section along the cylindrical body distal end side end surface 49 of the knob 52 is curved in an inverted S shape. Therefore, when removing the easy-opening portion 45, a finger is applied to the curved portion of the knob portion 52, and as shown in FIG. 10B, the knob is set with the central axis L3 of the cylindrical body distal end side end surface 49 as the center of torsion. The part 52 can be twisted and the easy-opening part 45 can be removed.

  A refill container 40H shown in FIG. 11A is obtained by forming the knob 52 from a corrugated plate member in the refill container 40G of FIG. 10A. As shown in FIG. 11B, the refill container 40 </ b> H can also be removed by twisting the knob 52.

  In addition, in the present container and the refill container of the present invention, the above-described deformation modes can be variously combined.

  Moreover, the refill container which implements the refilling method of this invention does not necessarily need that the easy-opening part was integrally shape | molded with the extraction | pouring nozzle. For example, the tip portion of the dispensing nozzle whose tip portion is cut obliquely may be sealed by welding of the film, and the film may be peeled off during use. In addition to the cap that covers the mouth of the refill body during distribution, a cap with a dispensing nozzle whose tip is cut obliquely as a refill cap that is attached to the mouth of the refill body during refilling It does n’t matter.

  The refilling method of the present invention is useful as a method for refilling liquid substances such as skin lotion and milky lotion from the refilling container into the present container.
