JP6250485B2 - Refill container pouring structure, refill container having the structure, and cosmetic product filled with liquid cosmetic in the refill container - Google Patents

Description

  The present invention relates to a refill container pouring structure (spout) for refilling a liquid into a container, such as liquid cosmetics, liquid detergents, liquid foods and drinks, and medicines, and more specifically, without improving the container body. The present invention relates to a refill container pouring structure that can be easily and surely refilled by being attached to a refill container, a refill container having the structure, and a cosmetic product in which the refill container is filled with a liquid cosmetic.

  Conventionally, it is common practice to sell only the contents for refilling detergents, shampoos and rinses, but in recent years, only cosmetics for refilling expensive liquid cosmetics have been sold. Increasing cases. And in the case of expensive cosmetics, unlike cheap shampoos and rinses, there is a strong demand to refill the contents without spilling them, so that the contents will not be wasted even in small quantities. .

  By the way, liquid cosmetics are usually sold in containers such as bottles. However, the mouth of such containers is moderately small in order to control the discharge amount of the contents to an appropriate amount for discharge. Is preferred. Therefore, the tip of the mouth of the container may be directly molded into a small diameter, but on the other hand, the filling port for filling the contents should be as wide as possible so as not to reduce the filling efficiency of the container. Is preferred. Therefore, a method of attaching an inner stopper having a small-diameter discharge port to the container port for discharge has been widely performed because it has the merit of satisfying both. The diameter of the outlet of the inner plug is determined by the viscosity of the liquid in the contents, but is generally about 3 mm to 12 mm, and is used for liquid cosmetics such as lotions and emulsions that are less viscous than shampoos and rinses. In some cases, the diameter is generally about 3 mm to 8 mm, and the diameter tends to be smaller. Therefore, it is difficult to refill from the discharge port without removing the inner plug from the container body.

  Therefore, when refilling liquid cosmetics, it is common to remove the inner stopper of the container from the mouth. However, the inner plug is forcibly fitted to the container mouth so that it cannot be removed in normal use, and the removal work is complicated. There is also a risk that cosmetics remaining in the container may be accidentally spilled during the work of removing the inner plug.

  In order to solve the above problems, Patent Documents 1 and 2 disclose a refilling container in which an inner stopper is removably attached to the mouth of the container. Although these things eliminate the troublesomeness associated with the removal of the inner plug as described above, since the inner plug is formed in a cap shape, the outer lid to be crowned from above is the container mouth portion. The design balance of the container may be lost. In addition, although the injection work is facilitated by removing the inner plug, the contents may spill out, for example, the spout of the refill container may come off the container mouth during refilling or the container may be overturned. there were. In addition, liquid cosmetics such as lotions and emulsions generally have a viscosity lower than about 6,000 mPa · s (25 ° C.), and are less viscous than shampoos and rinses. There was also a risk that the contents would spill out of the refill container before it was brought down to the container mouth.

  Therefore, Patent Document 3 includes a plug member in which a spout is closed by a closing body, and an operation member having a blade portion for pressing and breaking a weakened portion provided on the outer peripheral edge of the closing body. There is disclosed a refill container comprising

  However, this one is intended for the case where the mouth of the container body to be refilled is wide open at the time of refilling, such as a shampoo or rinse dispenser container. It was not supposed to be used, and it was difficult to refill without removing the inner plug.

  Furthermore, the container of Patent Document 3 includes a plurality of blades having blade portions connected to the break portion, and the one that protrudes highest among them comes into contact with the weakened portion first, and breakage starts from such a portion as a starting point. To do. That is, since the position of the weakened portion where the most projecting blade first comes into contact is determined by the circumferential direction of the operating member, the break start point cannot be specified without aligning the direction of the operating member. For this reason, it is necessary to form the weakened part with a thickness that can be ruptured so that the tip of the blade may come into contact with any part. On the other hand, the weakened part has the strength required for sealing (sealing). It was difficult to make adjustments to satisfy these requirements.

  Further, when the weakened portion is formed with the same thickness, all the weakened portions are broken at a stroke in the stage of proceeding the breakage of the weakened portion, and the closing body may be completely separated from the inner wall of the operation member. As a result, there is a possibility that the separated closing body may block the spout again as the contents are poured out. In Patent Document 3, in order to prevent such a phenomenon, the escape portion is provided by retreating greatly from the blade portion so that a load is not applied as much as possible on the connecting portion side of the weakened portion at the time of breakage. However, according to such a configuration, there is a problem that the length of the operation member in the vertical direction becomes long and the container becomes bulky.

  In order to solve such a problem, for example, it is conceivable to provide a connection part in which a part of the weakened part is formed thick to maintain the connection between the closing body and the inner wall. There is a need to position the contact portion of the blade portion to be contacted in advance, and the container of Patent Document 3 may increase the complexity of use such as adjusting the circumferential direction of the operation member each time.

  Therefore, the present invention overcomes the drawbacks of the conventional refill container refill mechanism, and can be used universally for cosmetic containers and other general liquid containers, regardless of whether or not the inner plug is attached, In particular, it is possible to reliably and easily refill the contents of a refilling destination container fitted with an inner stopper having a small-diameter discharge port by covering the mouth and neck of the refilling destination container with the inner stopper attached. Furthermore, a refill container pouring structure that can be easily operated without positioning the fracture start portion of the seal portion, a refill container having the structure, and a cosmetic product in which the refill container is filled with a liquid cosmetic Offering is the subject.

  The present invention solves the above-described problem, and covers the mouth and neck of the refill destination container, from the mouth of the refill destination container, or from the outlet of the inner plug attached to the refill destination container mouth. A refill container pouring structure capable of refilling the contents, a cap forming an insertion part into which the mouth and neck of the refill destination container can be inserted by a peripheral wall standing from the bottom and the peripheral edge of the bottom, and a top wall And a sliding member provided so as to be slidable in the axial direction within the insertion portion. The bottom of the cap is closed by a breakable seal portion. An outlet is formed, and a pouring nozzle that can be inserted into the mouth of the refill destination container or the outlet of the inner plug is erected on the top wall of the sliding member, and a pressing portion is provided on the lower surface of the top wall. Projected downward, from the dispensing nozzle to the pressing part The pouring path is formed in a penetrating manner, and the seal portion has a protruding point that partially protrudes toward the pressing portion, and the tip of the front pressing portion protrudes when the sliding member is pushed into the cap. The refill container pouring structure is characterized in that the seal portion starts to break from the vicinity of the protruding point in contact with the point.

  Furthermore, the present invention is a refill container having the refill container pouring structure, and a cosmetic product in which the refill container is filled with a liquid cosmetic.

  The refill container pouring structure according to the present invention, the refill container provided with the refill container pouring structure, or the cosmetic product in which the refill container is filled with the liquid cosmetics will spill contents even if the refill container is inverted. There is no fear, and even for containers such as cosmetics that are equipped with an inner stopper equipped with a small-diameter outlet, the dispensing nozzle is inserted into the inner stopper outlet by covering the neck of the container mouth The contents can be refilled easily and reliably without removing the inner plug from the refill container.

  Further, in the refill container pouring structure according to the present invention, the refill container provided with the refill container pouring structure, or the cosmetic product in which the refill container is filled with the liquid cosmetic, the tip of the pressing portion is always sealed first. It is possible to specify the fracture start part because it abuts the protruding point of the part, and it is easy to break by making the seal part thickness of the part thinner, or the seal part thickness of other parts A connection portion that is thicker and does not break can be provided. And since positioning of a sliding member is unnecessary also when using, refilling work is easy.

  Hereinafter, embodiments of the refill container pouring structure of the present invention will be specifically described with reference to the drawings. Note that the present invention is not limited to these embodiments.

  The refill container pouring structure of the present invention is attached to the main body of the refill container, and is provided with a cap 1 to be crowned on the mouth and neck of the container to be refilled and slidable in the axial direction inside the cap 1. It consists of a sliding member 2. Hereinafter, each part is explained in full detail.

  As shown in FIG. 1, the cap 1 forms an insertion portion 19 into which the mouth and neck of the cosmetic container can be inserted by a bottom portion 11 and a cylindrical peripheral wall 12 erected from the periphery of the bottom portion 11. A lid portion 13 for sealing the opening 15 of the insertion portion 19 is provided at the upper end so as to be opened and closed (the lid portion 13 is in an open state in FIG. 1). Further, a cylindrical base portion 14 hangs down on the back surface of the bottom portion 11, and an attachment portion 141 to which the refill container main body is attached is provided so as to protrude in the lateral direction. In the present embodiment, the base portion 14 and the attachment portion 141 are formed continuously and integrally. However, the attachment portion 141 may be formed as a separate member. In this case, the lower portion of the base portion 14 is formed as the attachment portion 141. It can be attached by inserting, fitting, or the like from the upper part.

  A spout 16 extends through the center of the bottom 11 of the cap 1, and a peripheral wall 18 stands up in the insertion portion 19 so as to surround the peripheral edge of the spout 16. The opening of the spout 16 is closed by the seal portion 17. As shown in FIG. 2 (a), the seal portion 17 is provided with an easily breakable portion 171 formed at a thickness that can be broken by pressing from the insertion portion 19 side. It is connected with the front-end | tip of the protruding item | line part 174 protruded cyclically | annularly on the surrounding surface. In this embodiment, the seal portion 17 is formed in a circular plate shape with the same material as the other portions of the cap 1, but can securely close the spout 16 during storage, and breaks due to pressing during refilling. The material and shape are not limited to this as long as they can be opened.

  The seal portion 17 is provided with a protruding point 173. The protruding point 173 is formed so as to protrude to the insertion portion 19 side with respect to the other portion of the seal portion 17. In the mode of FIG. 2A, the seal portion 17 is inclined at a predetermined angle from the horizontal direction in a side view. Thus, a part of the seal portion 17 located at the highest portion becomes the protruding point 173. Further, as in a different mode shown in FIG. 2B, the seal portion 17 is provided horizontally, and a convex protrusion point 173 that protrudes closer to the insertion portion 19 than other portions is provided in a part of the seal portion 17. May be. In addition, when forming the seal portion 17 so as to be inclined at a predetermined angle from the horizontal in a side view, the inclination angle is arbitrary, but it is preferable to form the seal portion 17 within a range of 0.1 to 45 degrees horizontally, Furthermore, 0.1 to 10 degrees is preferable.

  The easily breakable portion 171 may be provided on the entire outer peripheral edge of the seal portion 17, but as shown in FIG. 2, it is formed on a part of the outer peripheral edge of the seal portion 17 so as to be thicker than the easily breakable portion 171. A connection portion 172 that is not provided may be provided. As will be described later, since the easily breakable portion 171 starts to break from the vicinity of the protruding point 173, it is preferable that the connecting portion 172 is provided in the opposite portion of the outer peripheral edge of the seal portion 17 facing the protruding point 173. In addition, the easily breakable portions 171 other than the connecting portion 172 are basically formed with the same thickness. For example, only the easily breakable portion 171 near the protruding point 173 is formed to be thinner than the other portions. You may do it. Thereby, it is preferable because the breakable portion 171 near the protruding point 173 can be easily started to break.

  A locking projection 121 is continuously provided in the circumferential direction at the lower portion of the inner peripheral surface of the peripheral wall 12 of the cap 1, and a non-slip portion 122 is provided at the lower end of the outer peripheral surface of the peripheral wall 12. In the present embodiment, the lid 13 that can be opened and closed is integrally provided at the upper end of the peripheral wall 12, but the lid 13 may be a detachable member independent of the peripheral wall 12. An engaging portion 132 is suspended from the back side of the lid portion 13 and can be engaged with the inner peripheral surface of the peripheral wall 12 of the cap 1 when the lid portion 13 is closed. In addition, a pressing portion 131 projects from the center of the back side of the lid portion 13.

  As shown in FIG. 3, the sliding member 2 includes a ceiling wall 21 and a peripheral wall 22 that hangs down from the periphery of the ceiling wall 21, and a cylindrical pouring nozzle 23 stands vertically from the upper surface of the ceiling wall 21. A cylindrical pressing portion 24 is provided so as to protrude further downward from the lower end of the peripheral wall 22 from the lower surface of the top wall 21. A pouring passage 25 is continuously formed through the pouring nozzle 23 and the pressing portion 24. The dispensing nozzle 23 is formed to have an outer size that can be inserted into the outlet of the inner stopper of the container such as a cosmetic. However, as shown in FIG. 6, there is a slight gap between the outlet nozzle 23 and the inner stopper outlet 421. It is preferable to set an outer dimension so that air in the container escapes at the time of refilling. A plurality of ridges 211 are radially provided on the top surface of the top wall 21. Further, a locking groove 221a and a locking groove 221b are recessed in the upper and lower portions on the outer peripheral surface of the peripheral wall 22 continuously in the circumferential direction. In the above description, the case where the inner plug is attached to the refilling container has been described. However, the refill container pouring structure according to the present invention is directly from the mouth even when the inner plug is removed from the mouth of the container. In addition, a container having a discharge port at the front end of the mouth of the container without having an inner stopper can be refilled from the discharge port. As a mouth portion (discharge port) of these refill destination containers, those having a small diameter or a large diameter can be applied, but in the case of a small-diameter discharge port container, there is a slight gap between the dispensing nozzle 23 and the discharge port. It is preferable to set the outer dimension of the pouring nozzle 23 so that a gap is provided and air in the container escapes during refilling.

  In the above embodiment, the shape of the inner wall of the pouring nozzle 23, that is, the shape of the cross section of the pouring passage 25 is circular as shown in FIG. 3B, but in order to make the pouring passage 25 wider. For example, as shown in FIG. 4, one or more longitudinal grooves 26 may be formed in a part of the inner wall of the dispensing nozzle 23. The cross-sectional shape of the longitudinal groove 26 is substantially semicircular in FIG. 4A, but is not limited to this, and is a polygonal cross-sectional shape having one or more apex angles, for example, FIG. 4B. The shape may be as follows. The longitudinal groove 26 may be provided in parallel to the axis of the extraction channel 25, but may be provided in a spiral shape within a range that does not hinder the extraction of the contents.

  FIG. 5 is a cross-sectional view showing a state before refilling in which the sliding member 2 is attached in the cap 1. As shown in the figure, in the insertion portion 19 of the cap 1, the sliding member 2 is mounted with the tip of the dispensing nozzle 23 facing upward. The outer diameter of the peripheral wall 22 of the sliding member 2 is formed to be substantially the same as the inner diameter of the peripheral wall 12 of the cap 1, and in the state where they are not locked to each other, the axial direction (vertical direction in the drawing) within the insertion portion 19. The sliding member 2 is formed so as to be slidable. 5 shows a locked state before use, in which the locking protrusion 121 of the cap 1 is locked in the locking groove 221a of the sliding member 2, and the sliding member 2 is fixed. .

  In such a locked state, the lower portion of the pressing portion 24 of the sliding member 2 is inserted into the spout 16 in the peripheral wall 18 of the cap 1, and the tip portion 241 thereof is at the protruding point 173 of the seal portion 17. It is in a contact state. Specifically, the pressing portion 24 has a tip portion 241 projecting downward and a tip portion formed horizontally. On the other hand, the seal portion 17 is inclined and the projecting point 173 is more than the other portion of the seal portion 17. Projects upward. Therefore, a part of the tip portion 241 that corresponds to the protruding point 173 is in contact with the protruding point 173, and a gap is generated between the other tip portion 241 and the seal portion 17. Note that, as in this embodiment, the peripheral wall of the pressing portion 24 is formed thinner as it goes to the tip, and by making the tip portion 241 thinnest, the easily breakable portion 171 near the protruding point 173 is pressed. It is preferable because the breakage starts more easily when concentrated.

  In addition, the lid 13 is in a state in which the pressing portion 131 provided on the back surface of the lid 13 is in contact with the tip of the dispensing nozzle 23 in the closed state. As a result, the sliding member 2 is suppressed from above by the lid portion 13, and the seal portion 17 with which the tip portion 241 of the pressing portion 24 abuts is also indirectly suppressed from above by the lid portion 13. . As described above, the sliding member 2 is fixed and held with respect to the cap 1 by the locking of the locking groove 221a and the locking projection 121. In addition to this, the sealing member 17 is fixed by the lid portion 13 so that the seal portion 17 If the refill container (especially the pouch) is firmly gripped by the user, the seal portion 17 and the easily breakable portion 171 may be accidentally broken to the discharge passage 25 side due to an increase in the internal pressure of the container. Can be prevented. Further, when the lid 13 is closed, the sliding member 2 is in a state in which it cannot be contacted from the outside. Therefore, there is no possibility that the seal portion 17 is broken by being accidentally pushed from above, and a member that restricts the movement is also necessary. Absent.

  Hereinafter, a method for refilling the contents using the refill container pouring structure according to the present invention will be described taking a cosmetic container with an inner plug as an example. As shown in FIG. 6, the refill container pouring structure according to the present invention is attached to the mouth of the refill container 3. Further, the refill destination cosmetic container 4 is of a type in which the contents are poured out from the discharge port 421 provided in the inner plug 42, and the liquid cosmetic material having a low viscosity is used as the content. The diameter of 421 is formed smaller. The procedure for refilling the cosmetic container 4 is as follows. First, the refill container 3 is inverted and held with the cap 1 facing downward, and the lid portion 13 is opened (the lid portion 13 is omitted in FIG. 6). In this state, since the seal portion 17 is in a closed state, there is no possibility that the contents of the refill container 3 leak. Next, as shown in FIG. 6A, the mouth / neck part 41 of the cosmetic container 4 to be refilled is inserted into the insertion part 19 of the cap 1, and provided in the inner plug 42 of the cosmetic container 4. The dispensing nozzle 23 is inserted into the inside plug outlet 421. In addition, unlike this embodiment, when refilling a cosmetic container with the inner plug removed, the small-diameter discharge port is directly attached to the container mouth, or directly to the front end of the container without the inner plug. In the case of refilling into a container having a discharge nozzle 23 is inserted into the discharge port.

  Next, the mouth-and-neck portion 41 of the cosmetic container 4 is inserted into the insertion portion 19 until the protruding strip portion 211 of the sliding member 2 comes into contact with the top surface of the inner cap 42 of the cosmetic container 4. When the inner plug 42 and the protruding strip portion 211 of the sliding member 2 are in contact with each other, the mouth / neck portion 41 of the cosmetic container 4 is further pushed into the insertion portion 19 for insertion. As a result, an upward force is applied to the sliding member 2 by the mouth-and-neck portion 41. However, when the upward pressing exceeds a certain level, the locking groove 221a and the locking projection 121 are unlocked, and the sliding member 2 slides. The moving member 2 can further slide upward in the insertion portion 19. In order to unlock the locking groove 221a and the locking projection 121, it is necessary to push down the cap 1 with a certain force or more. At this time, a finger is put on the anti-slip portion 122 on the outer peripheral surface of the peripheral wall 12. By pushing down, it is possible to release the lock more easily without the force escaping.

  When the locking groove 221a and the locking projection 121 are unlocked, the sliding member 2 is prevented from moving only by the contact between the pressing portion 24 and the protruding point 173 of the sealing portion 17, and thus the pressing portion 24. The pressure concentrates on the contact portion between the tip portion 241 and the protruding point 173. When the pressure becomes a certain level or more, the fracture starts from the easily breakable portion 171 near the protrusion point 173, and the breakage proceeds in the circumferential direction as it is, and the easily breakable portion 171 is all broken leaving the connection portion 172. As a result, the seal portion 17 is opened, and the distal end portion 241 of the pressing portion 24 enters the spout 16 on the base portion 14 side. At this time, since only the easily breakable portion 171 is broken while leaving the connecting portion 172, the seal portion 17 is pushed into the cap 1 while being connected by the connecting portion 172 as shown in FIG. In the state where the sliding member 2 is deepest (upward in the drawing) and inserted into the insertion portion 19, the locking projection 121 of the cap 1 is locked in the locking groove 221b of the sliding member 2, At that position, the sliding member 2 is fixed. As a result, the blocking of the spout 16 by the seal portion 17 is completely released, and the contents can be poured from the refill container 3 to the cosmetic container 4.

  In the state of FIG. 6 (b), the contents are poured out from the unsealed spout 16 to the refill destination cosmetic container 4 through the pour-out path 25 of the sliding member 2 (arrow A). In addition, the inner diameter of the discharge port 421 of the inner plug 42 is set so that a void for air venting is created around the dispensing nozzle 23, and the top wall 21 and the inner plug 42 of the sliding member 2 are Since the close contact is prevented by the ridges 211, a gap is generated, and air in the container can be released from the gap, so that the refilling operation can be performed smoothly. In this way, since refilling is performed in a state where the dispensing nozzle 23 is inserted into the discharge port 421 of the inner plug 42, there is no need to remove the inner plug from the container body, and the mouth of the cosmetic container during the refilling operation. There is no risk that the spout will accidentally come off the section and the contents will spill.

  The cap 1 and the sliding member 2 of the refill container pouring structure according to the present invention can be formed of the same or different materials, for example, polyolefin resins such as polypropylene and polyethylene, polyethylene terephthalate, recycled polyethylene terephthalate, polyethylene Any of various synthetic resins such as naphthalate, polystyrene, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, polycarbonate, polyamide resin (nylon, etc.), polyacetal resin (POM), acrylic resin, etc. It can form with the combination of these.

  The material of the refill container attached to the cap 1 is not particularly limited. However, when a pouch formed of a synthetic resin film such as polyethylene or polyester is used, the container is deformed as the contents are poured out, and the inside of the container It is preferable because the air can be smoothly poured out from a thin spout such as the spout nozzle 23 without taking in air. Preferred embodiments of such a pouch container are listed below.
