  Mouthed pouches widely used for products such as beverages are also used as refill containers. When the main body container is refilled, the cap of the refill pouch is opened, and the plug is inserted into the mouth of the main body container. In that case, the contents may spill out with excessive momentum.

  Furthermore, for example, in the case of cosmetics to which no preservatives or the like are added, the quality cannot be maintained if dust, germs, etc. are mixed in, so measures are required to prevent foreign substances from being mixed during refilling. There are many cases.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the refill container stopper constituting the refill container according to this embodiment for refilling the contents of a main body container (not shown) will be described in detail. FIG. 1 is a plan view showing an example of a refill container stopper 1 according to the present embodiment. Here, for convenience of explanation, the left and right directions in FIG. 1 where the adhesive portions 11 and 11 projecting in a substantially triangular shape on both sides in the diameter direction from the circular plug body 10 in a plan view are left and right, respectively. The In addition, in the top view here, the side connected with a main body container in the case of refilling is shown.

  As shown in FIG. 1, the refill container plug 1 includes a plug body 10, a slide member 30, and a lid 50. Preferably, the plug body 10 is provided with a film seal 60 as a closing member that can be removed by a knob (not shown). In the plan view shown in FIG. Most of the components are hidden by the film seal 60. The structure in which the removable film seal 60 is attached to the side connected to the main body container, so that the inside of the plug body 10 can be kept clean until the film seal 60 is removed. Can be prevented from being mixed. Further, the structure in which the film seal 60 is attached prevents the contents from spilling during transportation and storage. A method of attaching the film seal 60 to the plug body 10 may be fusion by heat or the like, or attachment by an adhesive or the like.

  2 is a front view of the plug 1 for a refill container of FIG. 1, FIG. 3 is a side view thereof, and FIG. 4 is a bottom view thereof. The plug body 10 is configured in a cylindrical shape extending from one end to the other end. Here, the lower side in FIG. 2 where the bonding portion 11 is located is one end of the plug body 10, and the upper side in FIG. 2 where the film seal 60 is attached is the other end of the plug body 10. For convenience of explanation, the side where the one end (the lower side in FIG. 2) and the other end (the upper side in FIG. 2) of the plug body 10 are located is not limited to the plug body 10, and It is called the other end side.

  The plug body 10 has a cylindrical side wall portion 12. Furthermore, it is preferable that the plug body 10 has an outer peripheral rib 13 that protrudes outward from the outer peripheral surface of the other end of the side wall portion 12 as illustrated in FIG. 2 and the like. According to the configuration having the outer peripheral rib 13, the other end of the plug body 10 having a large surface area can be effectively utilized. More specifically, for example, the configuration having the outer peripheral rib 13 makes it easier to place the plug body 10 with the other end of the plug body 10 on the lower side or to attach the film seal 60 to the other end of the plug body 10. Can be.

  The outer peripheral rib 13 is not limited to the film seal 60, and may be used as an attachment portion for other closing members for preventing shrink wrapping or fitting with an overcap. These other blocking members can also prevent foreign matters such as dust and germs from entering from the outside during refilling. The material of these closing members is not particularly limited as long as foreign materials are prevented from being mixed in. For example, polyethylene, polypropylene, polyethylene terephthalate, polystyrene, polyvinyl chloride, and aluminum foil are used. In addition, it is preferable that the outer periphery rib 13 protrudes outward from the outer peripheral surface of the other end of the side wall part 12 at the point of the ease of attachment of a closure member. However, the outer peripheral rib 13 may have a form protruding inward as long as the condition that it can be molded and that the closing member can be attached is satisfied.

  The plug body 10 is provided with an adhesive portion 11 connected to one end of the side wall portion 12. The adhesion part 11 should just be formed according to the shape of the refill container which is the object of attachment of the plug 1 for refill containers.

  In the present embodiment, a boat-shaped adhesive portion 11 used for attachment to a container such as a pouch that is formed in a bag shape by being bonded after being overlapped with a flexible material is illustrated. That is, as shown in the bottom view of FIG. 4, the adhesive portion 11 is an arc-shaped central portion on both the front side (upper side of FIG. 4) and the rear side (lower side of FIG. 4) of the refill container stopper 1. And tangentially extending from the left and right sides. 2 is bonded to the inner surface of one side of the refill container, and in FIG. 3, the side surface of the back side of the bonded part 11 whose half is shown is the other side of the refill container. The refill container plug 1 is attached to the refill container.

  In addition, a circular opening is formed inside the arc-shaped part in the bottom view of the bonding part 11, and this opening forms the content flow path part 20. A lid 50 that seals the opening of the flow path portion 20 is attached to one end of the plug body 10.

  5 is a cross-sectional view taken along line VV in FIG. A screw, that is, a female screw 14 is formed on the inner peripheral surface extending from the other end of the side wall portion 12 of the plug body 10. The female screw 14 may have any shape as long as it engages with a screw formed at the mouth of the main body container, that is, a male screw, so that the main body container and the refill container are not loosened and are securely connected.

  More specifically, in accordance with the size of the external thread of the main body container, the root diameter of the female thread 14 (corresponding to the outer diameter of the inner peripheral surface of the side wall portion 12), the peak diameter, the pitch (on one end side, etc. The distance between each screw thread (screw valley) in the female threads 14 adjacent to the end side is formed. The female screw 14 may be any one corresponding to the male screw of the main body container, and the shape thereof may be a single-threaded screw or a multi-threaded screw such as a double-threaded screw or a triple-threaded screw. Furthermore, in a plan view, the winding angle, which is an angle that circulates from one end of the female screw 14 to the other end, is also an angle at which the main body container and the refill container are not loosened and are securely connected. good.

  The plug body 10 has a shoulder portion 15 that protrudes inward from one end of the inner peripheral surface of the side wall portion 12 on the one end side of the female screw 14. The shoulder portion 15 may be easily formed by matching the boundary between the adhesive portion 11 and the side wall portion 12.

  The lid 50 includes, for example, a flat top plate 51 and a cylindrical side wall 52. The top plate 51 has a shape corresponding to the opening formed in the bonding portion 11. The top plate 51 illustrated in FIG. 5 and the like is formed in a disk shape having a larger diameter than the opening formed in the bonding portion 11. The outer peripheral side of the side wall 52 extends from the top plate 51 to the other end side so as to be concentric with the top plate 51 with the same size as the opening formed in the bonding portion 11.

  The lid 50 may be configured to seal one end side of the plug body 10 so as to be removable from the plug body 10. Therefore, the lid 50 may not have the side wall 52 as long as the lid 50 can be sealed only by the top plate 51 and the one end side of the plug body 10. In such a case, for example, the top plate 51 may be formed in a flat plate shape having the same size as the opening formed in the bonding portion 11, and a circular recess may be formed instead of the side wall 52. Further, for example, the top plate 51 may be attached to the outer peripheral portion of the opening formed in the bonding portion 11 with a peelable adhesive force.

  The cylindrical slide member 30 is accommodated coaxially with the cap body 10 and the top plate 51 of the lid body 50 on the inner peripheral surface side of the plug body 10 and on the other end side of the lid body 50. Note that the slide member 30 is axially oriented with respect to the plug body 10 before being attached to the mouth of the main body container, that is, from the initial position shown in FIG. Configured to slide. The plug body 10 and the slide member 30 are liquid-tightly fitted, for example, at a liquid-tight fitting portion 21 near the shoulder 15.

  The slide member 30 has a push-up portion 31 connected to the lid body 50 on one end side of the liquid-tight fitting portion 21. Further, the slide member 30 has an opening 32 penetrating in a radial direction between the outer peripheral surface and the inner peripheral surface of the slide member 30 on one end side of the liquid-tight fitting portion 21. On the other hand, the slide member 30 has a flange 33 that protrudes outward from the outer peripheral surface on the other end side than the liquid-tight fitting portion 21. The other end side of the flange 33 of the slide member 30 is the extraction portion 34. An opening that penetrates the slide member 30 in the axial direction is formed on the other end side of the extraction portion 34. A space from the opening 32 through the inside of the slide member 30 and passing through the extraction portion 34 becomes the content flow path portion 20.

  Note that the configurations of the plug body 10, the slide member 30, and the lid body 50 on one end side from the flange 33 may be, for example, a square shape in a plan view and are not limited to a circle. However, these are preferably circular in view of ease of attaching the refill container to the main body container and ease of flow of the contents.

  FIG. 6 is a front view in which the initial position of the slide member 30 is schematically overlaid on FIG. The slide member 30 illustrated in FIG. 6 has a push-up portion 31 that extends in a leg shape from a push-up portion base portion 31b located in the middle of the axial direction toward a push-up portion top portion 31t on one end side. FIG. 6 shows an example in which four push-up portions 31 are formed at equal intervals in the circumferential direction of the slide member 30. The number of the push-up portions 31 is preferably an even number having a symmetric configuration from the viewpoint of formability, but is not particularly limited. Further, the push-up portion top portion 31t is continuously connected in the circumferential direction of the slide member 30. It does not matter even if it is a shape.

  The opening 32 is located between adjacent push-up portions 31, 31 and is formed in a cutout shape from the end on one end side of the slide member 30. The opening 32 does not necessarily reach the end of the slide member 30 as shown in FIG. However, when the opening portion 32 is formed from the end on the one end side of the slide member 30, it is easy to mold and the area of the opening portion 32 can be made wider, and the contents are refilled at the time of refilling. Can flow more smoothly.

  The push-up portion top 31t has an outer peripheral surface that is recessed inward than the push-up portion base 31b and has a smaller thickness. A slide member fitting portion 35 that protrudes outward and extends annularly in the circumferential direction of the slide member 30 is formed on the outer peripheral surface of the push-up portion top portion 31t. A slide member outer peripheral surface 36 is formed to have substantially the same diameter on the outer periphery in the region on one end side from the flange 33. A slide member first engagement portion 37 that protrudes outward and extends annularly in the circumferential direction of the slide member 30 is formed on the slide member outer peripheral surface 36 on the other end side of the liquid-tight fitting portion 21. . Similarly, a slide member second engagement portion 38 is formed on the other end side further than the slide member first engagement portion 37. Note that the flange 33 described above is formed further on the other end side than the slide member second engaging portion 38.

  FIG. 7 is an enlarged cross-sectional view of the main part of FIG. The plug main body 10 has a main body inner peripheral portion 16 having an inner peripheral surface having the same diameter on the one end side of the shoulder portion 15. The inner peripheral portion 16 has a slight gap between the opposed slide member outer peripheral surfaces 36. By this gap, the sliding of the slide member 30 with respect to the plug body 10 becomes good. Note that one end of the inner peripheral portion 16 of the main body is the peripheral edge of the opening formed in the adhesive portion 11 described above.

  In the vicinity of the shoulder portion 15 of the plug main body 10, a main body engaging portion 17 that protrudes inwardly from the main body inner peripheral portion 16 and extends in the circumferential direction of the plug main body 10 is formed. The main body engaging portion 17 is in close contact with the outer peripheral surface 36 of the slide member and constitutes a liquid tight fitting portion 21. The main body engaging portion 17 constituting the liquid tight fitting portion 21 can prevent the contents from entering between the plug main body 10 and the slide member 30. The liquid-tight fitting portion 21 may be configured so that the inner peripheral portion 16 of the main body and the outer peripheral surface 36 of the slide member are fitted in a liquid-tight manner, and is formed in any of the plug main body 10 and the slide member 30. It does not matter.

  Although the body engaging portion 17 is preferably formed in the vicinity of the shoulder portion 15 as illustrated in FIG. 7 from the viewpoint of easiness of movement of the slide member 30, the body engaging portion 17 is closer to one end than the shoulder portion 15. It may be formed in the body periphery 16. It should be noted that the plug body 10 has a single main body engaging portion 17 so that the slide member 30 can move more easily, and the plurality of main body engaging portions 17 makes the contents less likely to spill. It ’s okay.

  The outer peripheral surface of the side wall 52 of the lid 50 is fitted to the inner peripheral surface in the vicinity of one end of the body peripheral portion 16. The side wall 52 has a lid fitting portion 53 that protrudes inward from its inner peripheral surface and extends annularly in the circumferential direction. The refill container cap 1 is configured such that the slide member 30 and the lid 50 are connected by the slide member fitting portion 35 and the lid fitting portion 53 of the slide member 30. ing.

  The lid fitting portion 53 is formed on the gentle slope on the other end side and on the steep slope on the one end side. Since the other end side of the lid fitting portion 53 is formed on a gentle slope, the slide member 30 and the lid 50 can be easily connected. On the other hand, it is possible to make it difficult for the slide member 30 and the lid 50 to be detached from each other by forming one end of the lid fitting portion 53 on a steep slope. That is, the lid 50 is configured so as to remain integral with the slide member 30 even when it is separated from the plug body 10.

  With such a configuration, the lid 50 is mixed into the inside of the refill container after the sealing on the one end side of the plug body 10 is opened, and it becomes an obstacle when the refill container is squeezed or refilled. There is no need to block the internal flow path from the container to the main body container. Therefore, according to the plug 1 for a refill container having such a configuration, the contents can flow more smoothly.

  The slide member fitting portion 35 and the lid fitting portion 53 may be configured so that the slide member 30 and the lid body 50 are easily connected to each other and are not easily detached, and the shapes thereof are not limited. For example, either the slide member fitting part 35 or the lid fitting part 53 may be formed in a concave shape. Furthermore, the slide member 30 and the lid 50 may be bonded.

  As described above, the outer diameter of the slide member outer peripheral surface 36 is formed slightly smaller than the inner diameter of the main body inner peripheral portion 16. If the outer diameter of the slide member outer peripheral surface 36 is too close to the inner diameter of the main body inner peripheral portion 16, the slide member 30 becomes difficult to move with respect to the plug main body 10. Is not preferable because it is easy to enter, and the slide member 30 is likely to rattle.

  The range of movement of the slide member 30 toward the other end side is restricted by the lid body 50 connected thereto. In this state, the slide member first engagement portion 37 is provided at a position where the slide member first engagement portion 37 is engaged with the main body engagement portion 17, more specifically, on the other end side of the main body engagement portion 17. It is comprised so that 30 may not move to the one end side. Therefore, the positional relationship in which the main body engaging portion 17 and the slide member first engaging portion 37 are fitted and the one end side of the plug body 10 is sealed by the lid 50 is the initial position of the slide member 30. It is said that. In this state, even if the other end side of the plug body 10 is directed upward (the state shown in FIG. 7), the slide member 30 moves to the one end side, and the lid 50 is The structure is such that it does not come off the stopper body 10.

  On the other hand, the range of movement of the slide member 30 toward the one end side is regulated by the shoulder portion 15 of the plug body 10 and the flange 33. That is, the slide member 30 is configured such that the sliding of the flange 33 is completed when the flange 33 is pushed in from the initial position toward the one end and comes into contact with the shoulder 15. Since the shoulder 15 is configured to stop the movement toward the one end of the flange 33, it is easy to understand the completion of the setting when refilling. And since the shoulder part 15 is comprised so that the movement to the one end side of the flange 33 may be stopped, the slide member 30 goes too far to the one end side, etc., between the plug main body 10 and the slide member 30, etc. The contents will not leak out. The distance of movement of the slide member 30 can be appropriately designed according to the positional relationship between the shoulder portion 15 and the flange 33.

  In a state where the sliding of the slide member 30 is completed, the slide member second engaging portion 38 is provided at a position where the slide member second engaging portion 38 is fitted to the main body engaging portion 17, more specifically, at one end side than the main body engaging portion 17. The slide member 30 is configured not to move to the other end side. That is, the slide member 30 is configured such that the slide is completed after the flange 33 is pushed in the direction of one end and the slide member second engagement portion 38 gets over the main body engagement portion 17. . When the sliding of the slide member 30 is completed, the main body engaging portion 17 and the slide member second engaging portion 38 cause the one end side of the spigot main body 10 to face upward (inverted vertically from FIG. 7). ), The slide member 30 is configured not to move toward the other end.

  As described above, the refill container plug 1 has the configuration including the slide member first engaging portion 37 and the slide member second engaging portion 38, and thus the movement of the slide member 30 is stopped depending on the situation, so that it is more reliable. The contents can be prevented from spilling.

  The first space 22 is formed on the other end side of the flange 33 on the inner peripheral surface side of the side wall portion 12 when the slide member 30 is in the initial position. A second space 23 is formed. The refill container mouth plug 1 is configured such that the mouth of the main body container is inserted into the first space 22 when refilling. When the sliding of the slide member 30 is completed, that is, when the slide member 30 is pushed in the direction of one end and the shoulder portion 15 and the flange 33 come into contact with each other, The second space portion 23 disappears.

  The slide member 30 has an extraction portion 34 on the other end side than the flange 33. The extraction portion 34 is configured to extend from the flange 33 with the other end side as a tip. As illustrated in FIG. 7, the slide member 30 further includes an extraction portion guide surface 41 that contracts inward toward the other end side of the extraction portion side wall 40 that is the outer peripheral surface of the extraction portion 34. It is preferable. The tip of the refill container can be positioned with respect to the opening of the main body container by the dispensing portion invitation surface 41 having a tapered tip, and the refill container can be easily inserted. Furthermore, the side of one end of the pouring portion 34 is formed thicker than the inner surface of the mouth portion of the main body container, so that the pouring portion side wall 40 can be securely adhered to the inner surface of the mouth portion of the main body container. Therefore, the contents can be more reliably prevented from spilling from between the main body container and the refill container plug 1 at the time of refilling.

  As illustrated in FIG. 7, the slide member 30 is formed in an L shape in a side view on the extraction portion side wall 40 and the surface of the flange 33 connected to the extraction portion side wall 40 on the side of the extraction portion 34. It is preferable to further have a recessed groove 42. A gap is formed between the groove 42 and the inner surface of the mouth portion of the main body container in a state where the dispensing portion side wall 40 and the inner surface of the mouth portion of the main body container are in close contact with each other.

  As described above, the plug 1 for the refill container illustrated in FIG. 7 has a fitting surface other than the groove 42 when the inner surface of the mouth part of the main body container and the outlet part side wall 40 of the slide member 30 are fitted. While being liquid-tight, the groove 42 is configured to be a passage for air. Therefore, when refilling, the contents are not spilled more reliably from between the main body container and the refill container plug 1, and the air inside the main body container is easily discharged (replaced), so that smoother. The contents can be made to flow.

  The refill container plug 1 is preferably a material having excellent moldability, flexibility, excellent adhesion, and excellent adhesion to the refill container, preferably excellent thermal adhesion. More specifically, polyolefins such as low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, and polypropylene can be used as the material for the refill container stopper 1, and these thermoplastics can be used. A resin may be mixed. Then, using these thermoplastic resins, the plug body 10, the slide member 30, and the lid body 50 are formed by injection molding or the like, and the plug 1 for the refill container is produced by combining them. can do. Note that the slide member 30 and the lid 50 need not be separate bodies as long as they can be integrally molded.

  The refill container according to the present embodiment includes a refill container plug 1. FIG. 8 is a front view showing an example of a refill container 80 provided with the refill container plug 1 according to the present embodiment. FIG. 8 illustrates a refill container 80 in which the refill container plug 1 is attached to the pouch 70.

  The pouch 70 is formed in a bag shape by laminating the peripheral portions thereof after overlapping the flexible films. As shown in FIG. 8, the side surface 11 f on the front side of the bonding portion 11 is bonded to the inner surface 71 on one side of the pouch 70, and the side surface on the back side of the bonding portion 11 (not shown) is the other side of the pouch 70. Bonded to the inner surface of the side. The adhesion between the bonding portion 11 (front side surface 11f) and the pouch 70 (inner surface 71) is preferably heat fusion, but may be affixed with an adhesive or the like.

  In the manufacturing process of the refill container 80, the refill container plug 1 may be attached after the unillustrated contents are filled in the pouch 70, and the pouch 70 to which the refill container plug 1 is attached is previously filled. May be appropriately selected depending on the situation. First, when filling the contents of the pouch 70 to which the refill container cap 1 is attached, leave an unbonded peripheral edge for filling the contents so that the bonding is performed after filling the contents. Just do it.

  The film constituting the pouch 70 is appropriately selected according to the properties of the contents and the functions required for the film as a packaging material. The film may be a single layer or a multilayer. In the case of a multilayer film, for example, a two-layer structure in which a heat seal layer and a base material layer are laminated can be formed from the inside. By making the inside of the pouch 70 in contact with the refill container stopper 1 as a heat seal layer, the heat seal layer of the pouch 70 and the adhesive portion 11 of the refill container stopper 1 can be easily heat-sealed. it can.

  For the heat seal layer, a film made of polyolefin such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer and cyclic polyolefin having excellent heat seal properties may be used. The thickness of the heat seal layer is preferably 10 μm or more, more preferably 40 μm or more, and particularly preferably 80 μm to 200 μm. For the base material layer, for example, a biaxially stretched film manufactured from polypropylene, polyethylene terephthalate, or polyamide may be used. The thickness of the base material layer is preferably 10 μm to 50 μm, and more preferably 12 μm to 25 μm. Furthermore, the heat seal layer is preferably 2 to 20 times as thick as the base material layer, and more preferably 4 to 10 times thicker.

  If necessary, the multilayer film may be further provided with a barrier layer for adding a gas barrier property for preventing the transmission of oxygen, water vapor or the like, a light shielding property for preventing the transmission of visible light, ultraviolet light or the like. For example, a vapor deposition film such as aluminum oxide or silicon oxide, or an aluminum foil may be used for the barrier layer. The barrier layer may be a plurality of layers. Furthermore, the printing layer may be provided in the surface of the base material layer, or the back surface. There is no limitation on the method of laminating each layer, and for example, the layers can be laminated by dry lamination with a polyurethane adhesive. Furthermore, an outer layer may be provided on the surface of the base material layer.

  Further, the packaging form of the refill container 80 is not particularly limited. In addition to the illustrated pouch 70, a standing pouch, a two-side seal bag, a three-side seal bag, a four-side seal bag, a gusset bag, a pillow packaging bag, and a square bottom bag. It can be selected from various packaging forms such as a bag-in-box inner bag and others.

  Furthermore, the refill container 80 is not limited to the packaging container described above, and may be a paper container. When the refill container cap 1 is attached to the paper container, for example, it has a flange-like flat surface protruding outward from the side wall portion 12 in a plan view on the other end side of the bonding portion 11. And good. And what is necessary is just to adhere | attach the inner surface of the top plate of a paper container, for example, and the flat surface of the adhesion part 11 of the stopper 1 for refill containers. In addition, although it is preferable in terms of adhesiveness that the shape of the flat surface is a circle, it may be a quadrilateral, a polygon, or an indefinite shape. There is no particular limitation on the form of the paper container, and a shape suitable for refilling, for example, a flat top-type container such as a flat top type is preferable.

As the laminated material constituting the paper container, a paper material may be used instead of the above-described synthetic resin for the base material layer of the film constituting the pouch 70 described above. As the paper material, paperboard such as a coated ball, pure white roll paper, milk carton base paper, coated paper, craft paper, processed paper, and the like can be used. A plurality of paper material layers may be laminated. The basis weight of the paper material can be appropriately determined according to the form of the paper container, and is preferably 80 g / m ² to 600 g / m ² , and is 100 g / m ^{2 to} 450 g / m ² . More preferably. Furthermore, the thickness of the paper material is preferably 110 μm to 860 μm, and more preferably 140 μm to 640 μm.

  Furthermore, the refill container 80 is not limited to the packaging container or paper container described above, and may be a bottle. The bottle is preferably made of a flexible material from the viewpoint of ease of refilling. However, if the contents filled in the bottle have sufficient fluidity to easily flow down under its own weight, the bottle is flexible. It may be a material having no property, for example, a glass bottle.

  Next, the content refilling method by the refill container 80 which concerns on this embodiment is demonstrated in detail. FIG. 9 is a cross-sectional view of a main part showing a state when the refill container 80 is connected to the main body container 100, and FIG. 10 shows a state when the connection of the refill container 80 to the main body container 100 is completed. FIG. 9 and 10, the top and bottom of the plug body 10 are shown on the upper side and the other end of the plug body 10 is shown on the lower side. ing.

  At the time of refilling, first, the film seal 60 as a dust remover is peeled off from the plug body 10. Since the refill container mouth plug 1 is covered with the film seal 60 and is in a clean state, the refill is started in a state in which foreign matter such as dust or bacteria does not enter the mouth portion and the inner surface of the refill container 80. The refill container 80 is connected to the main body container 100 so that the first space part 22 exposed by peeling off the film seal 60 overlaps the mouth part 101.

  At the time of refilling, the refill container plug 1 is mounted upside down from above the main body container 100 with the mouth part 101 facing upward so that the other end faces downward. In this way, even if the refill container 80 is turned over, the contents are not spilled because the contents are sealed by the lid 50. Furthermore, since the main body engaging portion 17 and the slide member first engaging portion 37 are fitted in the initial position of the slide member 30, the lid 50 is not pushed in strongly from the main body container 100 side. Never open. Therefore, before the refilling is started, the contents are not spilled from the refilling container 80 when the refilling container 80 is attached to the main body container 100. Furthermore, since it is not necessary to turn over the main body container 100 when refilling, even if there is a residual liquid in the main body container 100, refilling can be performed without spilling the contents.

  The pouring part 34 of the slide member 30 is drawn into the mouth inner surface 102 of the main body container 100 by forming the pouring part invitation surface 41 in a tapered shape at the tip thereof, and the opening 103 of the main body container 100. It is easy to be inserted into. And when the extraction | pouring part 34 is inserted in the opening part 103, the opening part inner surface 102 and the extraction | pouring part side wall 40 fit liquid-tightly. Therefore, at this time, when the contents flow from the refill container 80 to the main body container 100, the liquid leakage from the fitting portion between the mouth inner surface 102 and the extraction portion side wall 40 can be prevented. ing. However, at least if the mouth top surface 105 and the flange 33 are fitted in a liquid-tight manner, liquid leakage will occur even if the mouth inner surface 102 and the extraction portion side wall 40 are not fitted in a liquid-tight manner. Can be prevented.

  Next, when the refill container plug 1 is rotated with respect to the main body container 100, the male screw 104 (screw) of the main body container 100 and the female screw 14 of the side wall portion 12 of the main plug body 10 are engaged with each other. The mouth plug 1 is screwed into the mouth portion 101 of the main body container 100. In that case, since the refill container cap 1 is centered with respect to the main body container 100 by the pouring part side wall 40 of the outer surface of the pouring part 34 and the side wall part 12 of the plug main body 10, And it can rotate smoothly. Here, the centering is to bring the rotation axis of the external thread 104 of the main body container 100 in which the deviation occurs and the rotation axis of the female thread 14 of the plug body 10 so as to coincide with each other.

  When the refill container stopper 1 is screwed into the mouth portion 101, the flange 33 of the slide member 30 contacts the mouth top surface 105 of the main body container 100. For this reason, the slide member 30 is pushed into the one end side by the main body container 100, and is rotated with respect to the plug main body 10 so that the volume of the second space portion 23 is reduced (the upper side in FIG. 9). )

  When the slide member 30 moves to one end side, the push-up portion 31 pushes up the lid body 50 that has sealed the one end side of the plug body 10, and the lid body 50 is detached from the plug body 10. To do. At this time, since the force of engagement between the male screw 104 and the female screw 14 is used, the lid 50 can be pushed up by the push-up portion 31 without requiring a strong force. Even when the lid 50 is detached from the plug body 10, it remains integral with the slide member 30 and does not separate, and therefore does not fall into the refill container 80. Therefore, the lid 50 is mixed into the refill container 80, which obstructs the refill container 80 from being squeezed out, or blocks the contents flow path from the refill container 80 to the main body container 100. There is nothing.

  As shown in FIG. 10, the slide member 30 protrudes from one end of the plug body 10, and the flow path portion continues from the inside of the refill container 80 to the opening 32, the inside of the slide member 30, and the extraction portion 34. When 20 is communicated, the contents are poured out from the refill container 80 into the main body container 100. In FIG. 10, the flow f of the contents is schematically shown by arrows. As illustrated in FIG. 10, when the opening 32 is formed from the end on one end side of the slide member 30, the area of the opening 32 can be increased, and the contents are more refilled at the time of refilling. It is preferable that it can flow smoothly.

  While the contents flow from the refill container 80 to the main body container 100, the main body engaging portion 17 constituting the liquid tight fitting portion 21 and the slide member outer peripheral surface 36 are liquid tight over the entire circumference in the circumferential direction. It is mated. As a result, between the side wall portion 12 and the mouth portion 101 of the main body container 100 through the second space portion 23 and the first space portion 22 from between the main body inner peripheral portion 16 and the slide member outer peripheral surface 36. It is possible to prevent liquid leakage from the portion up to the point.

  Further, when the refill container stopper 1 is rotated with respect to the main body container 100, the volume of the second space portion 23 is gradually reduced. When the flange 33 comes into contact with the shoulder portion 15 of the spigot body 10, the second space portion 23 disappears, and the rotation of the refill container 80 relative to the main body container 100 and the pushing up of the lid 50 by the slide member 30 are completed. . When the sliding of the slide member 30 is completed, the slide member 30 is not moved to the other end side (the lower side in FIG. 10) by the main body engaging portion 17 and the slide member second engaging portion 38. For this reason, while the flow path part 20 continues to be stably secured, when removing the refill container 80 from the main body container 100, the extraction part 34 can be quickly removed from the mouth part 101. The completion of rotation is not limited to this, and can be defined by various methods such as completion of engagement between the main body container 100 and the female screw 14 and contact between the main body container 100 and the plug body 10. .

  The opening 32 when the sliding toward the one end side of the slide member 30 is completed is more outward in the axial direction than the one end of the plug body 10 (upper side in FIG. 10). It is preferable that the contents can be taken widely and the contents can flow more smoothly during refilling.

  As described above, according to the configuration of the refill container stopper 1 according to the present embodiment, the refill container stopper 1 is attached to the mouth portion 101 of the main body container 100 and the contents are accidentally spilled until the contents are poured out. There is nothing. Further, the configuration having the film seal 60 prevents foreign matters such as dust, dust and bacteria from entering from the outside. And according to the structure of the plug 1 for refill containers which concerns on this embodiment, since the pushing-up part 31 pushes up the cover body 50 reliably and sufficient flow path can be ensured, refilling at high speed is possible.

  As described above, the refill container plug 1 according to the present embodiment slides in the axial direction on the side of the cylindrical plug main body 10 extending from one end to the other end and the main body inner peripheral portion 16. A cylindrical slide member 30 that seals one end of the plug body 10 and a lid 50 that is connected to the slide member 30. The plug body 10 has an inner peripheral surface that extends from the other end. It has the side wall part 12 in which the female screw 14 was formed, the plug main body 10 and the slide member 30 are fitted by the liquid-tight fitting part 21, and the slide member 30 is more than the liquid-tight fitting part 21. A flange 33 protruding outward from the slide member outer peripheral surface 36 on the other end side, and an opening 32 penetrating between the slide member outer peripheral surface 36 and the inner peripheral surface on one end side of the liquid-tight fitting portion 21. A male screw 104 formed in the mouth part 101 of the main body container 100, and a side wall part. When the second female screw 14 is engaged, the mouth inner surface 102 and the slide member outer peripheral surface 36 are fitted, and the mouth top surface 105 pushes the flange 33, so that the lid 50 is moved to the slide member. 30 is configured so as to be separated from the plug main body 10 while being integrated.

  According to the configuration of the present embodiment, the refill container stopper 1 is overlapped with the main body container 100, and the contents are sealed by the lid 50 unless the refill container 80 is rotated with respect to the main body container 100. For this reason, until the refill is actually performed, the content does not leak out regardless of the orientation of the refill container 80. That is, when the main body container 100 and the refill container 80 are connected, the contents are not excessively spilled, and even if there is residual liquid in the main body container 100, the refill can be performed without any problem. Furthermore, according to the configuration according to the present embodiment, the lid 50 that seals the contents remains integral with the slide member 30 and is not separated even after the flow path portion 20 is opened and refilling is started. For this reason, the lid 50 is mixed into the refill container 80 and becomes a hindrance when the refill container 80 is squeezed out, or the content flow path from the refill container 80 to the main body container 100 is blocked. There is no end.

  Therefore, according to the present embodiment, it is possible to provide the refill container plug 1 and the refill container 80 that flow smoothly without refilling the contents during refill.

  Furthermore, the refillable container stopper 1 according to this embodiment is preferably provided with a removable film seal 60 at the other end of the side wall portion 12. By comprising in this way, it can prevent that a foreign material mixes in the case of refilling.

  The present disclosure can be suitably used for the refill container plug 1 that replenishes the contents of the main body container 100 and the refill container 80 including the same. However, the present disclosure is not limited to the above-described embodiments. The contents filled in the refill container 80 of the present disclosure are also not particularly limited as long as it has fluidity and can be used after being refilled, and foods such as cosmetics, detergents, pharmaceuticals, beverages, seasonings, and the like, Others may be used. Furthermore, since the refill container 80 provided with the refill container plug 1 according to the present disclosure is effectively prevented from being contaminated with foreign substances during refilling, it is meticulous like a preservative-free cosmetic. It is also suitable for containing sensitive contents. Further, the contents can be applied even if it is a powder as long as it has fluidity. And since the refill container 80 of this indication has airtightness and can also provide the barrier property with respect to oxygen, water vapor | steam, etc., it is suitable for long-term storage.
