Description

  The present invention relates to a spout for a refill container and a refill container with a spout, and more particularly to a container that opens and closes a spout by moving the cap up and down without detaching the cap.

  In refill containers that contain fluid contents (shampoos, rinses, liquid detergents, etc.), containers with spouts (plastic extractors) are generally prevalent in consideration of refillability. A spout attached to a refill container is generally known with a spout attached to a screw cap. Moreover, various forms have been proposed for the opening and closing mechanism of the spout in this type of spout. For example, in the prior art described in Patent Document 1 below, a cover member is put on the outer periphery of a cylindrical pouring portion having a tip hole, and the lid member closes the tip hole of the pouring portion and the contents outside. A cover member from a spout closed state in which a closed portion closes the tip hole to a spout open state in which a pouring channel is formed from the opened tip hole to the opening. Is slidable up and down with respect to the pouring part. Then, the protruding locking portion on the inner periphery of the lid member moves between the first locked portion and the second locking portion, which are horizontal annular grooves provided on the outer periphery of the extraction portion, so that the lid member is poured. Locked to the exit in an open / closed state. Moreover, in the prior art described in the following patent document 2, it replaces with the structure which can be slid up and down of the prior document 1, and the cap (lid member) provided with the thread (screw) and the plug main body (pour-out part). The spout can be opened and closed by the vertical movement of the lid member by relative rotation.

  Large-capacity refill containers that contain contents for daily use are sold so that the number of purchases can be reduced. In such a refill container, since the capacity of the refill container is larger than the capacity of the container to be refilled (refill container), the refill container does not become empty in one refill operation, and once the spout is closed, The refill container will be stored until a refill is required.

  At this time, in the conventional spout that opens and closes the spout with a screw-type cap, there is a tendency that the cap is lost and the spout cannot be stored in the closed state. Also, since the spout cannot be stopped unless the spout spout is turned upward once, if the refill destination container is filled with the contents remaining in the refill container during refilling, do not hesitate. The outlet will be on the top, and liquid dripping from the spout and overflow from the refill destination container are likely to occur.

  On the other hand, the prior art of Patent Document 1 described above is a state in which the extraction portion and the lid member are relatively slid in a state where the extraction portion and the lid member are inserted into the mouth portion of the refill destination container, Since the spout can be opened, it is not impossible to close the spout (pour channel) with the spout spout down.

  However, in one form of the prior art of Patent Document 1 described above, the opening portion and the closing portion each have a non-circular shape such as substantially one letter, and the lid member has the dispensing portion around the central axis in the spout open state. Since it can rotate, when changing from the spout open state to the closed state, there is a possibility that the position in the circumferential direction shifts and the spout closed state cannot be set again. In another form, since the opening and the closing part are circular, it is easy to make the spout closed again, but in order to make the spout open, the lid member can be moved up and down once relative to the dispensing part. Since it cannot slide up and down unless it is rotated, the operation up to the spout open state straddles twice, making it difficult to understand and complicated.

  Moreover, although the prior art of patent document 2 makes it possible to open and close the pouring plug (spout) by performing the rotation and vertical movement of the lid member at once by the screw of the plug body and the lid member, the lead of the screw is short. The lid must be rotated many times. If the lead is large, the lid member will be rotated too much by mistake and the screw will come off, making it difficult to re-seal, or the lid member's retaining protrusion will lock. There is a risk that the cover member will get over the protruding shape and the lid member may come off from the extraction portion.

  The present invention has been proposed to address such problems. That is, the present invention provides a spout provided in a refill container to prevent loss of a lid member required when performing refilling multiple times, and to open and close the spout with good workability with the spout spout at the bottom. That the contents of the refill container remain, the spout can be quickly closed immediately before the refill container is filled, and the filling of the contents can be stopped. It is a problem.

  In order to solve such a problem, the present invention has the following configuration.

  A fixed pouring body having a base end portion, a pouring portion, and an opening communicating from the base end portion inward side to the pouring portion outer side, and a pouring outlet at the tip, covering the pouring portion A movable pouring body, and the pouring portion and the movable pouring body contact the pouring port and the pouring portion by rotating the movable pouring body around a vertical axis of the pouring portion. A spout for a refill container, wherein the spout is connected via engagement of an annular cam groove and an engagement protrusion, which switches between a closed state and a separated and open state. Or the refill container with a spout provided with the said spout for refill containers.

  According to the spout for a refill container having such characteristics or a refill container with a spout equipped with the spout, the movable pouring body can be rotated around the vertical axis of the pouring part with the spout outlet facing downward. Thus, it is possible to switch between a closed state in which the spout and the extraction portion are brought into contact with each other and sealed, and an open state in which the spout is separated and opened. Thus, the spout can be opened and closed with good workability even when the spout spout is in the down position.

  Moreover, even if the contents remain on the refill container side with the spout of the spout down, the spout can be opened and closed simply by rotating the movable pouring body at hand. . Thereby, immediately before the refill destination container is filled, the spout can be quickly closed and filling of the contents can be stopped. Further, since the movable pouring body serving as the lid member is always connected to the fixed pouring body through the engagement between the annular cam groove and the locking projection, even when refilling is performed multiple times. There is no problem of losing the movable dispenser.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same function, and repeated description in each drawing will be omitted as appropriate.

  As shown in FIGS. 1 and 2, a spout for a refill container (hereinafter referred to as a spout) 1 according to an embodiment of the present invention includes a fixed pouring body 10 and a movable pouring body 20. The fixed pouring body 10 and the movable pouring body 20 are manufactured by, for example, injection molding a synthetic resin such as polypropylene into a mold. As shown in FIG. 2, by providing the spout 1 in the refill container 2, it becomes a refill container with a spout. Here, the refill container 2 is a pouch container such as a standing pouch for containing fluid contents, and is formed from a synthetic resin film having a proper function, a film laminated with aluminum foil, etc. For example, it is heat sealed.

  As shown in FIGS. 1 to 3, a fixed pouring body (spout body) 10 to be mounted on the refill container 2 includes a pouring portion 14 including an inner tubular portion 11 and an outer tubular portion 12, and a proximal end portion. 13 is an integral molded product. The inner cylindrical portion 11 is a hollow cylindrical portion having a top surface portion 11A closed at the distal end and having a side surface opening 11C on the side surface 11B, and has a proximal end opening 11D on the inner side of the proximal end portion. . The base end opening 11D opens into the refill container 2, and forms a pouring flow path that leads from the base end opening 11D through the inside of the inner cylindrical portion 11 to the side opening 11C and leads to the outside of the pouring portion. Is done. Further, a seal portion 11E is formed on the outer periphery of the top surface portion 11A.

  The outer cylindrical portion 12 surrounds the side surface 11B of the inner cylindrical portion 11 and has an open end 12A at a position lower than the top surface portion 11A. The inside of the outer cylindrical portion 12 serves as a discharge channel for the contents that have flowed out from the side opening 11C. An annular cam groove 12C is provided between the two annular cam rails 12D on the outer peripheral surface 12B of the outer cylindrical portion 12.

  The proximal end portion 13 integrally supports the inner tubular portion 11 and the outer tubular portion 12 on the proximal end side, and has a close contact surface 13A and a flange 13B to which the heat seal portion of the refill container 2 is in close contact. Yes. The base end portion 13 has a flat shape extending laterally (direction corresponding to the side portion of the refill container 2), and has a boat shape in which the thickness decreases from the center of the base end portion 13 toward the side end. Moreover, the base end part 13 is integrally provided with a pair of projecting legs 13 </ b> C extending inside the refill container 2 as necessary. The pair of protruding legs 13C can adjust the outflow amount of the contents to the proximal end opening 11C by pressing the inner side with a finger.

  On the other hand, the movable pouring body 20 includes an inner tube portion 21 and an exterior portion 22 as shown in FIG. The inner cylindrical portion 21 has a spout 21A at the tip, surrounds the inner cylindrical portion 11 of the fixed pouring body 10, and is slidably mounted in close contact with the outer cylindrical portion 12 of the fixed pouring body 10. Has been. In the illustrated example, a close sliding portion 21 </ b> B is provided on the outer peripheral surface of the inner cylindrical portion 21, and a seal portion is formed between the inner peripheral surface of the outer cylindrical portion 12.

  The exterior portion 22 integrally supports the inner cylinder portion 21 on the distal end side, and is mounted so as to cover the outer cylindrical portion 12 of the fixed pouring body 10. On the inner surface of the exterior portion 22, an engagement protrusion 22 </ b> A that engages with an annular cam groove 12 </ b> D (between the annular cam rails 12 </ b> C) provided on the outer peripheral surface 12 </ b> B of the outer cylindrical portion 12 is provided. Further, on the outer surface of the exterior part 22, an operation protrusion 22 </ b> B for rotating the movable pouring body 20 is formed along the central axis O. The distal end portion of the exterior portion (movable pouring body 20) 22 has a tapered shape, and a distal end tapered portion 22C reaching the spout 21A is formed.

  Thus, the outer cylindrical portion 12 of the fixed pouring body 10 and the exterior portion 22 of the movable pouring body 20 are connected via the engagement between the annular cam groove 12C and the engaging protrusion 22A. The annular cam groove 12C is fixedly poured by rotating the exterior portion 22 of the movable pouring body 20 around the vertical axis of the pouring portion 14 in the fixed pouring body 10 (the central axis O of the outer cylindrical portion 12). The movable pouring body 20 is slid up and down along the central axis O with respect to the boring body 10 and is provided on a corrugated annular track. The corrugated annular track includes a portion that rises in proportion to the amount of rotation, a portion that falls, and a connecting portion that smoothly connects the portions that rise and fall. As a result, the closed state of the spout 1 that contacts and seals the spout 21A and the seal portion 11E on the outer periphery of the top surface portion 11A and the open state of the spout 1 that opens while the spout 21A and the seal portion 11E are spaced apart are switched. It is done.

  FIG. 4A shows an open state of the spout 1. In this state, as shown by the arrows in the figure, the base end opening 11D of the inner cylindrical portion 11 reaches the inner side of the outer cylindrical portion 12 via the side surface opening 11C, and further the spout from the inner side of the inner cylindrical portion 21. A pouring channel reaching 21A is formed. Here, since the pouring channel is tapered toward the pouring port 21A, the seal portion 11E of the inner cylindrical portion 11 disposed in the inner tube portion 21 functions as a restriction for the pouring channel. Will do. Thereby, the amount of extraction from the outlet 21A can be changed in accordance with the separation state between the outlet 21A and the seal portion 11E (the gap amount between the tapered portion 22C and the seal portion 11E). How to change the extraction amount depending on the rotation amount of the movable extraction body 20 can be appropriately set according to the form of the annular cam groove 12C.

  FIG. 4B shows the closed state of the spout 1. In this state, since the sealing surface 11E of the inner cylindrical portion 11 is in close contact with the inner surface of the spout 21A, the spout 21A is closed.

  The annular cam groove 12 </ b> C is provided in an annular shape (endless shape) on the outer peripheral surface 12 </ b> B of the outer cylindrical portion 12. Thereby, even if the movable pouring body 20 is rotated around the central axis O in either the left or right direction, the engaging protrusion 22A rotates together with the movable pouring body 20 along the wave-shaped annular track of the annular cam groove 12C. While moving up and down, the spout 1 can be opened and closed. Further, the spout 1 can be opened and closed by continuing to rotate the movable pouring body 20 in one direction, and the movable pouring body 20 that is a lid does not come off the fixed pouring body 10. At this time, a deep groove portion, a jumping projection having a size enough to prevent the engaging projection 22A from dropping off the annular cam groove 12C, etc. are provided in the annular cam groove 12C, so that the fully opened position as shown in FIG. Alternatively, the fully closed position as shown in FIG. 4B can be recognized by the operator based on the click feeling or the rotational resistance feeling of the movable pouring body 20.

  In the example of the annular cam groove 12C shown in FIG. 3, the fixed pouring body 10 and the movable pouring body 20 are positioned in a sealed state within one circumference (360 °) of the outer peripheral surface 12B of the outer cylindrical portion 12. The annular cam groove bottom dead center is provided at two locations (on the front side and the back side) separated by a half circumference (180 °). As a result, the spout 21A and the seal portion 11E that are in a sealed state are sealed again each time the movable pouring body 20 (exterior portion 22) is rotated by 180 ° around the central axis of the outer cylindrical portion 11. . At this time, the operation protrusions 22B provided on the outer periphery of the exterior portion 22 are provided every 180 ° around the central axis O, and when the spout 21A and the seal portion 11E are sealed, the same side as the side of the base end portion 13 (pouch By arranging the operation protrusion 22B on the side of the refill container 2 in the width direction, etc., it becomes easy for the operator to visually recognize the fully closed position.

  Furthermore, in this example, the annular track of the annular cam groove 12C is axially symmetric with respect to the central axis O, and has two top dead centers and two bottom dead centers with respect to one turn (360 °). Are formed by two cycles of orbits. The engagement protrusions 22A are also provided at two locations symmetrically with respect to the central axis O (at the same height position apart from the half circumference by 180 °).

  Further, on the upper top dead center position of the upper rail of the annular cam rail 12D that forms the annular cam groove 12C, when the engagement protrusion 22A of the movable ejector 20 is engaged with the annular cam groove 12C, the engagement protrusion 22A is formed. A gentle slope portion is provided to enable easy passage over the upper rail of the annular cam rail 12D.

  Such a spout 1 has a spout 21A by turning the movable pouring body 20 around the central axis O in a state where the spout 1 is directed downward and the spout 1 is inserted into the opening of the refill destination container. Open for refilling. At this time, since the distal end tapered portion 22C is provided in the exterior portion 22, the spout 21A can be easily inserted. Further, since the spout 21A is tapered to have a relatively small diameter, it can be used regardless of the opening diameter of the container to be refilled.

  Such a spout 1 or a refill container 2 provided with the spout 1 is particularly effective when the refill container 2 has a relatively large capacity and is subdivided into a refill destination container. In such a case, it is required to close the spout 21 </ b> A while the spout 1 faces downward with the contents remaining in the refill container 2. At this time, since the spout 1 can be brought into a closed state by simple or operation of rotating the movable pouring body 20, even if the contents remain in the refill container 2, Immediately before the refill destination container is filled, the spout 1 can be quickly closed to stop filling the contents. Moreover, since the movable pouring body used as a cover member is always connected with the fixed pouring body, the malfunction which loses a cover member does not arise. Accordingly, when refilling a plurality of times, the refill container 2 can be stored with the spout 21A always closed.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention. Is included in the present invention.

  The fixed pouring body 10 and the movable pouring body 20 may have a structure in which an annular cam groove is provided on one side and an engagement protrusion is provided on the other side and can be connected by engagement. For example, the annular cam groove is formed on the movable pouring body. The engaging protrusion may be provided on the fixed pouring body.

  Instead of providing the annular cam groove 12C between the two upper and lower annular cam rails 12D, for example, the annular cam groove 12C may be formed in a concave groove shape directly on the outer peripheral surface 12B.

  Further, the annular track of the annular cam groove 12C only needs to be movable up and down by rotating the movable pouring body, and may be, for example, one inclined elliptical track for one cycle. In addition, a waveform trajectory that rises and falls sinusoidally according to the amount of rotation, a trajectory that combines curved displacements such as an arc, an ellipse, and a parabola, and the like may be set as appropriate according to the number of periods. Moreover, you may provide a circular track | orbit in step shape so that the movable pouring body 20 may rise and fall in multiple steps according to the amount of rotation.

  In addition, regarding the number of vertical displacements per one rotation of the annular track of the annular cam groove 12C and the positions where the engagement protrusions 22A are installed, one engagement protrusion is provided for one or more cycles of the annular track, or the number of the number of cycles or less. A plurality of engaging protrusions may be provided at locations separated by a multiple of the periodic interval.

  Furthermore, although the side opening 11C and the base end opening 11D are provided as openings in the above-described embodiment with respect to the pouring channel, they pass through the opening that leads from the inside of the base end of the fixed pouring body to the outside of the pouring part. The shape is not particularly limited as long as it is formed so as to reach the spout of the movable pouring body. For example, as in another embodiment shown in FIG. 5 (spout 101), the base end opening 11D is directly connected to the base end portion 13 so as to directly pass between the outer side of the inner cylindrical portion 11 and the inner side of the outer cylindrical portion 12. (The side opening 11C in the embodiment of FIG. 5 may be changed by 90 degrees around the central axis O with respect to the side opening 11C in the embodiment of FIGS. 3 and 4). Alternatively, a plurality of base end openings 11D may be provided at equal intervals on the circumference as small holes that communicate only between the outside of the inner cylindrical portion 11 and the inner side of the outer cylindrical portion 12, and the side openings 11C may not be provided. In that case, you may make the inner side cylindrical part 11 into a solid column shape. Or the pouring channel of patent documents 2 may be sufficient.

  Furthermore, the refill container 2 is not limited to a pouch container, and may be a bottle-shaped container such as a bottle formed by blow molding. In this case, the base end 13 is fitted and sealed in accordance with the shape of the refill container mouth side. The shape should be easy to do.
