Description

  The present invention relates to a plug for a refill container, and more particularly, to a plug for a refill container that is attached to cover the refill outlet of the refill container for refilling the contents of the refill container.

  In recent years, with regard to synthetic resin containers that contain various liquids and other contents, it has become possible to reduce the environmental burden, and various thin-walled containers have been developed that reduce the amount of resin used. Yes. In addition, refill containers such as pouches are often used as containers for storing various detergents and foods. The refill container can be refilled or refilled with a refilled container equipped with a discharge nozzle and a pour-out unit, so that an expensive refill container can be used for a long time without being discarded each time. Make it available.

  On the other hand, a refill container such as a pouch is formed of a soft packaging material that is rich in flexibility and flexibility, and the container is likely to be deformed during refilling work, and is likely to be extremely unstable. In addition, the refilling operation of the contents by the refill container can be performed by, for example, a) cutting the tip of the nozzle part, b) pouring at an angle, c) holding the tilted state, d) squeezing, e) not spilling. Although it is carried out by work steps such as discarding with care, refilling the contents by these work steps is time consuming and easily spills the contents during the work.

  For this reason, a refill container has been proposed in which the refill outlet of the container formed of the soft wrapping material is securely connected to the mouth portion of the refill container to improve refillability ( For example, see Patent Document 1 and Patent Document 2). In the refill container of Patent Document 1, a plug body having a cylindrical portion with an internal thread formed on the inner peripheral surface is attached to the refill outlet, and is formed on the outer peripheral surface of the mouth portion of the refill container. The internal thread of the cylinder part is screwed to the external thread, and the refill outlet of the refill container is connected to the neck of the refill container.

  In the first embodiment, the mounting cylinder 17d surrounds the circular outflow opening 17b and the insertion opening 19 continuous therewith in an annular shape, and is preferably arranged concentrically with the top plate 17a. It is provided so as to protrude downward from the lower surface of 17a and to have a substantially cylindrical shape (see FIG. 5C). Accordingly, the outflow cylinder 17c and the mounting cylinder 17d are provided on the upper surface side and the lower surface side of the top plate 17a so as to have different cylindrical shapes with their center positions shifted.

  In the first embodiment, a guide outer wall 20 and a guide inner wall 21 are further provided to protrude outward from the top plate 17b in the outflow direction. In the first embodiment, since the mouth 16 of the refill container 15 has a cylindrical shape (see FIG. 2), the outer wall 20 has the outer shape of the mouth 16 of the refill container 15. As the shape along, it is an arc-shaped wall plate portion provided with an arc-shaped inner peripheral shape portion 20a on the entire inner peripheral surface. The guide outer wall 20 is located between the inner peripheral shape portion 20a of the inner peripheral surface and the outflow tube 17c at a portion close to the dividing portion 23 of the outflow tube 17c, and more than the wall thickness of the neck portion 16 of the refill container 15. While maintaining a slightly large gap, the two sides of the portion adjacent to the dividing portion 23 are extended to the peripheral portion of the top plate 17b while being curved with a curvature radius substantially the same as the outer diameter of the neck portion 16. Is provided.

  By providing the guide outer wall 20, when refilling the contents, the inner peripheral shape portion 20 a of the guide outer wall 20 is guided along the outer peripheral surface of the mouth portion 16 of the refill container 15, The operation of pushing the refill container stopper 10 toward the refill container 15 while keeping the outer peripheral surface of the outflow cylinder 17c along the inner peripheral surface of the mouth 16 of the refill container 15 is performed in a more stable state. In addition, it is possible to guide more smoothly so that the end surface portion of the mouth neck portion 16 of the refill container 15 is surely brought into contact with the distal end surface 18d of the pushing convex portion 18c of the plug lid 18. .

  In the first embodiment, since the mouth 16 of the refill container 15 has a cylindrical shape (see FIG. 2), the inner wall 21 of the refill container 15 has the inner peripheral shape of the mouth 16 of the refill container 15. Is a circular arc-shaped wall plate portion provided with an arc-shaped outer peripheral shape portion 21a on the entire outer peripheral surface. The guide inner wall 21 is provided in a state of being divided by a dividing portion 21b that is arranged so as to overlap with the dividing portion 23 of the outflow cylinder 17c. Further, the guide inner wall 21 is divided so as to circumscribe the outflow cylinder 17c at the dividing parts 23 and 21b by overlapping the dividing part 21b on the dividing part 23 of the outflow cylinder 17c from which the pushing projection 18c protrudes. It extends from the parts 23 and 21b to both sides. Further, the guide inner wall 21 is provided in a state in which the outer peripheral surface which is the outer peripheral shape portion 21 a is curved with a curvature radius substantially the same as the inner diameter of the mouth 16 of the refill container 15. As a result, in the first embodiment, the gap between the outer peripheral shape portion 21a of the guide inner wall 21 and the inner peripheral shape portion 20a of the guide outer wall 20 is slightly smaller than the thickness of the neck 16 of the refill container 15. A large interval is maintained.

  By providing the guide inner wall 21, when refilling the contents, the outer peripheral shape portion 21 a of the guide inner wall 21 is guided along the inner peripheral surface of the mouth portion 16 of the refill container 15, The operation of pushing the refill container stopper 10 toward the refill container 15 while keeping the outer peripheral surface of the outflow cylinder 17c along the inner peripheral surface of the mouth 16 of the refill container 15 is performed in a more stable state. In addition, it is possible to guide more smoothly so that the end surface portion of the mouth neck portion 16 of the refill container 15 is surely brought into contact with the distal end surface 18d of the pushing convex portion 18c of the plug lid 18. . In addition, a gap slightly larger than the wall thickness of the neck 16 of the refill container 15 is maintained between the outer peripheral shape portion 21a of the guide inner wall 21 and the inner peripheral shape portion 20a of the guide outer wall 20. The operation of pushing the plug container 10 for the refill container toward the refill container 15 can be performed in a more stable state, and the end surface portion of the mouth 16 of the refill container 15 is plugged with the plug lid 18. It is possible to guide more smoothly so as to surely contact the front end surface 18d of the pushing projection 18c.

  As shown in FIGS. 4 (a), 4 (b) and 6, the plug lid 18 constituting the refill container plug body 10 is mounted so that its outer peripheral surface is in close contact with the inner peripheral surface of the mounting cylinder 17d of the plug body 17. It consists of a wall surface portion 18a, a blocking plate portion 18b having a planar shape similar to the hollow cross-sectional shape of the mounting cylinder 17d, and a pushing convex portion 18c erected upward from the peripheral portion of the blocking plate portion 18b. In the first embodiment, the mounting wall surface portion 18a is formed by the outer peripheral surface of a flat cylindrical portion 18e having an outer diameter similar to the inner diameter of the cylindrical mounting tube 17d. The blocking plate portion 18b is formed by a circular plate-shaped portion that is integrally formed so as to cover the upper opening end surface that is the outer surface in the outflow direction of the cylindrical portion 18e. The pushing projection 18c is formed by a quadrangular prism portion that is integrally formed so as to stand upward from the peripheral portion of the circular plate-like blocking plate portion 18b and outward in the outflow direction.

  The stopper lid 18 has the pressing projection 18c and the blocking plate portion 18b facing outward in the outflow direction, and the insertion projection 19c is inserted through the insertion port 19 formed in the top plate 17b from the inner side in the outflow direction of the plug body 17. By being pushed into the mounting cylinder 17d of the plug body 17, the mounting wall surface portion 18a formed by the outer peripheral surface of the cylindrical portion 18e is firmly fitted into the inner peripheral surface of the mounting cylinder 17d, and is fitted into the mounting cylinder 17d. The plug body 17 is integrally mounted. Further, by this, the plug lid 18 causes the pushing convex portion 18c inserted through the insertion port 19 to protrude outward from the top plate 17b along the outflow tube 17c in the outflow direction, and the substantially rectangular tip of the pushing convex portion 18c. The plug body 17 is integrally mounted with a substantially half portion of the surface 18d arranged radially outside the outer peripheral surface of the outflow cylinder 17c.

  Here, in the first embodiment, the plug lid 18 projects the pushing projection 18c at a height lower than the tips of the outflow tube 17c, the guide inner wall 21 and the guide outer wall 20 of the stopper body 17, and the stopper body 17 It is attached as one. The pushing convex portion 18c protrudes at a height lower than the tip of any one of the outflow cylinder 17c, the guide inner wall 21 and the guide outer wall 20, so that, for example, when the refill container 11 is dropped, the plug for the refill container When the tip of the body 10 collides with the floor surface or the like, the load at the time of collision is received by the outflow cylinder 17c, the guide inner wall 21 or the guide outer wall 20, so that the load at the time of the collision is passed through the pushing projection 18c. It is possible to effectively avoid being transmitted to. As a result, it is possible to effectively prevent the plug lid 18 from being detached from the mounting cylinder 17d due to the plug lid 18 being inadvertently moved with respect to the plug body 17, and the content liquid flowing out. When being displayed at the store, it is possible to effectively prevent the content liquid from flowing out due to the pushing-in part of the stopper lid being intentionally pushed and unsealed.

  Moreover, it is preferable that the stopper lid 18 is made of a material having a specific gravity lower than that of the refill content liquid stored in the refill container 11. Since the plug lid 18 is made of a material having a specific gravity lower than that of the contents liquid, when the contents are refilled, the refill container 11 is turned upside down and the refill container stopper 10 is replaced with the refill container 15. The plug lid 18 pushed out into the refilling container 11 after being dropped from the mounting cylinder 17d by pushing toward the end is moved upward by the action of buoyancy due to the contained liquid, and thus pushed out. It is possible to effectively prevent the plug lid 18 from inhibiting the outflow of the content liquid through the outflow opening 17b.

  In the refill container plug 10 of the first embodiment having the above-described configuration, the plug lid 18 is attached to the mounting cylinder 17d from the inside in the outflow direction, thereby closing the outflow opening 17b and the plug lid 18 being the plug main body. In a state of being integrally attached to 17, it is used by being bonded and fixed to the mouth portion 12 of the refill container 11 through the fixing skirt portion 22 of the plug body 17 (see FIGS. 1 to 3).

  And according to the plug body 10 for the refill container of this 1st Embodiment, it attaches to the mouth part 12 of the refill container 11, and is used, and the mouth part of the refill container 11 by simple operation and simple force. The refilling outlet 12a at the tip of 12 can be communicated with the neck 16 of the refill container 15, and the content liquid can be refilled in the refill container 15 in a stable state. .

  That is, according to the first embodiment, the refill container plug 10 includes the plug main body 17 and the plug lid 18, and the plug main body 17 surrounds the outflow opening 17 b from the top plate 17 a in the outflow direction. And a mounting cylinder 17d that surrounds the outflow opening 17b and protrudes inward in the outflow direction from the top plate 17a. The plug lid 18 is attached to the inner peripheral surface of the mounting cylinder 17d. Part 18a, a closing plate part 18b, and a pressing projection 18c erected from the closing plate part 18b. The pressing projection 18c extends from the top plate 17b along the outflow tube 17c via the insertion port 19. In this state, a part of the front end surface 18d of the push-in convex portion 18c is preferably arranged on the outer side in the radial direction from the outer peripheral surface of the outflow tube 17c.

  Therefore, according to the refill container stopper 10 of the first embodiment, as shown in FIG. 2 and FIGS. 3A and 3B, for example, in the inverted state in which the mouth 12 is disposed downward, The plug 10 attached to the refill container 11 is plugged so that the refill container 11 is gripped and the outer peripheral surface of the outflow cylinder 17c is along the inner peripheral surface of the mouth 16 of the refill container 15. The pushing convex portion 18c in which the end surface portion of the mouth portion 16 of the refilling container 15 is in contact with the tip surface 18d by a simple operation of a series of one action and a simple force only to be pushed toward the replacement container 15 is provided. The outflow opening 17b can be easily opened by extruding the inside of the refill container 11 and dropping the stopper lid 18 from the mounting cylinder 17d. Further, this makes it possible to easily communicate the refill outlet 12a of the refill container 11 with the neck 16 of the refill container 15 through the opened outflow opening 17b, and preferably the outer peripheral surface. The outlet tube 17c is inserted into the neck 16 of the refill container 15 along the inner peripheral surface of the refill container 15 so that the refill container 11 and the plug for the refill container 15 are filled. In a state where 10 is stabilized with respect to the refill container 15, the content liquid can be easily and smoothly refilled while flowing the content liquid from the refill container 11 into the refill container stopper 10.

  FIGS. 7A and 7B show a refill container stopper 30 according to a second preferred embodiment of the present invention. The plug container 30 for the refill container of the second embodiment has substantially the same configuration as the plug container 10 for the refill container of the first embodiment, while the outflow tube and the portion of the inner wall of the guide are the first. It is different from that of the refill container stopper 10 of the embodiment. In the second embodiment and the third embodiment described later, the same components as those in the refill container stopper 10 of the first embodiment are denoted by the same reference numerals as those in the first embodiment. The description is omitted.

  That is, in the refill container plug 30 of the second embodiment, no guide inner wall is provided, and the outflow direction from the top plate 17a surrounds the outflow opening 17b formed in the top plate 17a of the plug body 17. The outflow cylinder 17c ′ protruding outward is a cylindrical portion having a substantially elliptical hollow cross-sectional shape.

  Also by the refill container plug 30 of the second embodiment, a series of one-action simple operations in which the plug 30 attached to the refill container 11 is pushed into the refill container 15. The outflow opening 17b can be easily opened by pushing the pushing projection 18c into the refill container 11 and dropping the stopper lid 18 from the mounting cylinder 17d. The same effect as the plug 10 for a refill container is exhibited. Further, the arc-shaped portion having a large curvature of the outflow tube 17c ′ having a substantially elliptical hollow cross-sectional shape is curved with a curvature radius substantially the same as the inner diameter of the mouth portion 16 of the refill container 15 and is opposed to the guide outer wall 20. Between the outer peripheral surface of the arc-shaped portion having a large curvature of the outflow cylinder 17c ′ and the inner peripheral shape portion 20a of the guide outer wall 20 opposed thereto, and the meat of the mouth 16 of the refill container 15 By maintaining a space slightly larger than the thickness, the arc-shaped portion having a large curvature can be functioned as a guide inner wall.

  FIGS. 8A and 8B show a refill container stopper 40 according to a third preferred embodiment of the present invention. The plug container 40 for the refill container according to the third embodiment has substantially the same configuration as the plug container 10 for the refill container according to the first embodiment, but the outflow tube and the insertion port are the same as those of the first container. It is different from that of the refill container stopper 10 of the embodiment. Moreover, in the plug body 40 for the refill container of the third embodiment, neither the outer wall of the guide nor the inner wall of the guide is provided, and the mounting wall surface portion and the closing plate portion of the stopper lid are provided in the first embodiment. It differs from that of the plug 10 for a refill container in the form.

  That is, in the plug container 40 for the refill container according to the third embodiment, the outflow cylinder 17c ″ that surrounds the outflow opening 17b formed in the top plate 17a of the plug body 17 and protrudes outward from the top plate 17a in the outflow direction is The insertion portion 19 ″ through which the pushing projection 18c ″ of the plug lid 18 ″ is inserted is not continuous with the outflow opening 17b, and the constriction portion 24 is formed. In this portion, an opening is formed adjacent to the radially outer side of the outflow cylinder 17c ″. The plug lid 18 ″ has a hollow cylindrical shape on its mounting wall surface portion 18a ″. Since the closing plate portion 18b ″ closes the inner portion of the mounting wall surface portion 18a ″ in the outflow direction, the mounting wall surface portion 18a ″ and the closing plate portion 18b ″ form a concave shape that opens outward in the outflow direction. doing.

  Also by the plug body 40 for the refill container of the third embodiment, a series of one-action simple operations of simply pushing the plug body 40 attached to the refill container 11 toward the refill container 15. Since the pushing projection 18c ″ is pushed out into the refill container 11 and the stopper lid 18 ″ is dropped from the mounting cylinder 17d, the outflow opening 17b can be easily opened, so that the first embodiment is performed. The same effect as the plug container 10 for a refill container is obtained. Further, since the mounting wall surface portion 18a ″ and the blocking plate portion 18b ″ of the stopper lid 18 ″ form a concave shape that opens outward in the outflow direction, the stopper lid 18 ′ is pushed out into the refill container 11. In this case, since air is held in the concave shape of the blocking plate portion 18b ′, the air is not only buoyant by the content liquid but also buoyant by the air, so that the outflow of the content liquid is hindered. Can be more effectively avoided.

  The present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the content to be refilled from the refill container to the refill container using the plug for the refill container does not necessarily need to be a content liquid such as a liquid detergent, and other fluids such as powders It may be the contents. In addition, it is not always necessary to use a plug for a refill container attached to the neck of a bottle-shaped refill container, and various refill containers formed of other soft packaging materials such as pouches and gusset bags. It can also be used by covering the refill outlet. The refill container does not have to be provided with the mouth portion. Furthermore, the plug for the refill container can be attached to the refill container as a single unit by covering the refill outlet by seal bonding or the like without using the fixed skirt portion.

  In addition, the outflow tube and the mounting tube may be a cylindrical portion having a hollow cross-sectional shape other than a circle or an ellipse, and the outflow opening of the plug body and the closing plate portion of the plug lid have a circular planar shape. It is not necessary. The wall surface of the plug lid does not need to have a hollow cylindrical shape. For example, the closure plate can be formed by thickening the closure plate and bringing the outer peripheral surface into close contact with the inner peripheral surface of the mounting cylinder. You may make it give a function as a mounting | wearing wall surface part to a part. The pushing convex portion standing from the peripheral portion of the blocking plate portion is not necessarily a quadrangular column portion, and may be a columnar portion or a cylindrical portion having another shape. Furthermore, as shown in FIG. 9, the top plate and the fixed skirt portion of the plug body can be formed with their center positions shifted. The shape of the top plate is not necessarily circular, and may be any shape such as a rectangle.

  Furthermore, as shown in FIG. 10, in the region inside the outflow cylinder 51, the push-in convex portion 54 of the plug lid 53 is inserted continuously to the opening peripheral edge of the outflow opening 52 or adjacent to the outflow opening 52. By forming the insertion port 55 to be formed, the outflow cylinder 51 can be the refill container stopper 50 installed on the radially outer side than the insertion port 55. According to the refill container stopper 50 shown in FIG. 10, for example, when refilling the content liquid into the refill container whose outer diameter of the mouth portion is substantially the same as the inner diameter of the outflow tube 51, The outflow opening 52 can be easily opened by a series of one-action simple operations in which the stopper 50 attached to the refill container is pushed into the refill container. The same effect as the plug 10 for a refill container of one embodiment is exhibited.

  In each of the above-described embodiments, as shown in FIGS. 11A and 11B, a position correcting rib 90 that protrudes inward from the inner surface of the outer wall 20 and preferably has an inclined inner surface is provided. You can also. When the plug 10 for the refill container is positioned and pushed into the mouth part of the container to be refilled, for example, the inclined surface of the position correction rib 90 protrudes along the outer peripheral surface of the mouth part by projecting along the outflow cylinder 17c. It is possible to guide the pushed-in projection 18 c of the stopper lid 18 that has been made to the front end side of the mouthpiece 16. As a result, the outflow opening can be opened more easily by causing the pushing projection 18c of the plug lid 18 to contact the tip of the mouth neck portion securely and dropping the plug lid 18 from the mounting cylinder 17d. .

  Also, as shown in FIGS. 12 and 13, by providing cuts 91 on both sides of the position correction rib 90, the position correction rib 90 stands from the top plate 17a of the plug body 17 in a leaf spring shape. It can also be provided in a state of being provided. Thus, for example, even when a male thread ridge is formed on the outer peripheral surface of the mouth portion of the refill container and the position correcting rib 90 is easily interfered with, the position correcting rib 90 is elastically deformed outward. Thus, it becomes possible to avoid interference. Further, since the position correcting rib 90 is elastically deformed outward, an inward elastic biasing force is generated, so that it is possible to accurately guide the pushing convex portion 18c to the tip side of the mouth portion of the refill container. . As a result, the refilling operation can be performed more smoothly.
