Description

  The present invention relates to a liquid dispensing container having an overcap that is attached to a container with a nozzle cap having a nozzle for dispensing a content liquid and is detachably attached to the nozzle cap.

  Conventionally, the nozzle cap has a bottle (container), a nozzle cap that has a nozzle for pouring the content liquid and is attached to the bottle, and a measuring unit that measures the content liquid poured out from the nozzle cap. A liquid dispensing container comprising a measuring cap that is detachably attached is used (see, for example, Japanese Patent No. 3810571: Patent Document 1).

  In this type of liquid pouring container, the liquid dripping on the outer wall of the nozzle or the liquid that has flowed out too much and returned to the nozzle cap flows down the inclined bottom part coupled to the nozzle bottom part, and is bottled from the through hole formed in the lower end part of the bottom part. To be collected within. At this time, if this liquid remains in the container without being completely recovered, the remaining liquid will flow down from the side of the nozzle the next time the liquid is poured out from the nozzle, causing dripping. In some cases, the surroundings were soiled.

  In addition, the nozzle cap nozzle is designed to have a small cross-section for flow control because the amount of effluent is too low and the metering workability is reduced. On the other hand, since the nozzle cross-section is small, the nozzle cap is refilled from the pouch. There is a problem that it is difficult to do.

  In order to prevent the above-mentioned dripping, in Patent Document 1, the gap between the outer wall surface of the measuring cylinder and the cylindrical wall portion of the nozzle cap is 0.5 mm to 2.0 mm, and the cylindrical wall portion of the nozzle cap or the measuring cap One in which at least one or more vertical ribs are provided on any of the outer wall surfaces of the measuring cylinder is disclosed. The vertical ribs prevent liquid from remaining in the gap between the measuring cap and the nozzle member.

  In JP 2000-302155 A (Patent Document 2), the nozzle bottom portion of the nozzle cap and the boundary portion between the nozzles and the boundary portion between the nozzle bottom portion and the cylindrical wall portion are less than half the width dimension of the annular space. Discloses a liquid dispensing container in which a curved surface portion having a curvature radius is formed. The curved portion formed at the boundary between the nozzle bottom and the nozzle of the nozzle cap and the boundary between the nozzle bottom and the cylindrical wall facilitates the flow of the liquid agent and prevents liquid from remaining around the nozzle bottom. ing.

  In addition, in Japanese Utility Model Publication No. 08-066761 (Patent Document 3), an extraction cap body in which the entire area of the air cylinder and the entire area of the damming portion are located within the vertical extension width range of the extraction cylinder opening portion of the nozzle cap. Disclosure. According to this, it forms so that the end surface outer edge of the extraction | pipe cylinder standing installation base end may be located in the upper rank rather than a damming-part opening edge. With this configuration, liquid outflow prevention from the air hole to the outside of the extraction cylinder and smooth outflow of liquid by integrating the outlet and the air hole are achieved.

  Japanese Patent Application Laid-Open No. 2000-25821 (Patent Document 4) discloses a liquid dispensing container in which a liquid inclined guide portion for collecting liquid is provided on the outer peripheral wall surface of the dispensing tube toward the opening for collecting liquid. Has been. With this configuration, the liquid dripping to the outside of the dispensing cylinder is effectively collected in the container.

  Further, in Japanese Patent Laid-Open No. 2001-199465 (: Patent Document 5), a liquid fluidizing portion is provided on at least one of a spout tip end portion of a measuring cap and an inner surface of the nozzle cap in a state where the measuring cap is attached to the nozzle cap. The container with a cap which has (the uneven | corrugated | grooved part or step part notched in sawtooth shape) is disclosed. When the measuring cap is screwed onto the nozzle cap, the fluidizing portion applies an external force to the residual liquid in the vicinity of the measuring cap tip and the inner surface of the nozzle cap due to the rotational movement of the measuring cap, and fluidizes it into the container. We are trying to recover efficiently.

  Further, in Japanese Patent No. 3479261 (PTL 6), ribs are provided on both sides of the slit on the outer surface of the dispensing cylinder, the slit width on the proximal end side of the dispensing cylinder is narrowed, and the slit width on the distal end side is set wide. And the rib is disclosing the container with a cap provided corresponding to the whole region of the part with a narrow slit width at least. By providing the rib, liquid leakage from the dispensing cylinder slit to the outside is prevented, a large amount of liquid is prevented from flowing out, and the liquid return time is shortened.

In Japanese Utility Model Publication No. 07-51481 (PTL 7), there is a liquid return hole at the bottom of the pouring tube, a step is formed at the base of the pouring tube, and the inside of the cap and the container communicate with the step. A liquid container pouring tap is disclosed in which a communicating hole is formed and walls extending in the circumferential direction are formed above and below the communicating hole. According to this, the remaining liquid is efficiently recovered in the container by the two liquid return portions.

  However, each of the above-mentioned conventional technologies eliminates the point that the liquid remaining in the nozzle cap flows down from the side of the nozzle when the content liquid is poured out from the nozzle next time, causing dripping and smearing the surroundings. It was impossible.

  In addition, the nozzle cap nozzle is designed to have a small cross-section for flow control because the amount of effluent is too low, so the workability of the metering is reduced, and it is difficult to refill from the pouch because the nozzle cross-section is small. This problem cannot be solved.

  The present invention has been made in view of the above-mentioned circumstances, and prevents liquid dripping from the nozzle, and the amount of effluent can be freely adjusted. The present invention is also intended to provide a liquid dispensing container in which air replacement is effectively performed and refilling workability is excellent even when the liquid is poured into the container.

The present invention temporarily stores a content liquid dispensed from the nozzle body having a container body that contains the content liquid, a nozzle member that is attached to a mouth portion of the container body and that dispenses the content liquid. A liquid dispensing container having a storage cylinder and a cap that is detachably attached to the nozzle member;
The nozzle member rises from the base of the nozzle in the axial direction, and has a generally bowl-shaped nozzle having an open portion on its side surface, and two or more slopes descending toward the center coupled to the base of the nozzle An inclined plane bottom composed of a plane, an annular inclined bottom coupled outwardly from the nozzle base, and a space between the nozzle through the inclined planar bottom and the annular inclined bottom and axially forward A cylindrical wall portion that rises toward
The storage cylinder portion of the cap can be inserted into the space, and an opening for discharging the content liquid and replacing the air from the lowermost portion toward the inner wall surface of the nozzle is provided at the bottom of the inclined plane. A pair of guide walls for controlling the liquid flow width rising from the periphery of the opening to the axial direction on the inner wall surface of the nozzle,
A spout of the content liquid is formed at the tip of the nozzle,
A first flange portion for covering the outer wall of the storage cylinder portion of the cap in a bowl shape and detachably attaching to the cylindrical wall portion of the nozzle member;
The liquid dispensing container is characterized in that a second flange portion is provided on the outer wall surface of the cylindrical wall portion of the nozzle member so as to cover the outer wall surface in a bowl shape and to be attached to the container body mouth portion.
In the present invention, in the nozzle member, it is preferable that the width of the side opening portion of the nozzle is not more than half of the circumferential length of the nozzle.
In the present invention, it is preferable that a step is provided in a vertical direction at a joint portion between the annular inclined bottom portion and the inclined flat bottom portion.
In the present invention, it is preferable that the opening portion is elongated from the bottom of the inclined flat surface to the inner wall surface in the liquid outflow direction.
In the present invention, it is preferable that a groove is provided along a joint portion between the annular inclined bottom portion and the bowl-shaped nozzle.

  According to the liquid dispensing container of the first aspect of the present invention, the bottom of the inclined plane composed of two or more inclined planes descending toward the center is directed from the lowermost end toward the inner wall surface of the nozzle. Since the opening for pouring the content liquid and performing air replacement is provided, the amount of liquid to be dispensed can be controlled by designing the opening area small even when the nozzle diameter is large. In addition, since the residual liquid flows toward the opening at each of the two or more inclined flat bottoms, the liquid hardly remains in the nozzle. Further, by increasing the nozzle diameter, the volume of the annular space around the nozzle is reduced, and the probability that the liquid remains in this portion is reduced, so that liquid dripping from the side of the nozzle is less likely to occur.

  Further, by increasing the nozzle diameter, it is easy to fix the pouch spout against the nozzle when it is refilled with the pouch, so that workability when refilling from the pouch is improved.

  Further, since the nozzle has a bowl-like shape having an open portion on its side surface, the liquid can be poured from the open portion, and the refill workability is excellent.

  In addition, the pair of guide walls that control the liquid flow width provided on the inner wall surface of the nozzle serves as a guide that supports the pouch spout when refilling, so that the mouth of the pouch can be prevented from shifting, improving refill workability. An excellent effect can be achieved.

  By providing a pair of guide walls for controlling the liquid flow width on the inner wall surface of the nozzle so as to rise from the edge of the opening toward the axial direction, the opening is large in the vertical direction and air replacement can be ensured. The liquid guided to the guide wall can surely flow into the opening without stagnation.

  In the present invention, since the bottom portion of the nozzle member has a funnel shape, the liquid remains in the nozzle member by setting the width of the side opening portion of the nozzle to less than half (50% or less) of the circumferential length of the nozzle. However, most of the remaining liquid on the open side of the nozzle flows into the bowl-shaped nozzle when it is poured out next time, and does not cause dripping from the side of the nozzle.

  In the present invention, if a step is provided in the vertical direction at the joint between the annular inclined bottom portion and the inclined flat bottom portion, even if liquid remains in the nozzle member, the liquid remaining on the nozzle release portion side is poured out next. Occasionally, most of it flows into the bowl-shaped nozzle, and it is difficult for dripping from the nozzle side.

  In the present invention, the amount of liquid dispensed when the liquid is poured out is increased by opening the inner side of the pair of guide walls in the liquid outflow direction from the bottom of the inclined plane to the inner wall surface of the opening. In addition, air replacement at the time of refilling can be performed reliably, and the liquid can be poured smoothly.

  In the present invention, by providing a groove along the junction between the annular inclined bottom and the bowl-shaped nozzle, the liquid present in the annular inclined bottom can be quickly flowed down along the groove.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the liquid dispensing container includes a nozzle body 16 having a container main body 10 that stores the content liquid, and a nozzle 14 that is attached to the mouth portion 12 of the container main body 10 and that discharges the content liquid. And a cap 20 having a storage cylinder portion 18 for temporarily storing the content liquid poured out from the nozzle 14 and detachably attached to the nozzle member 16.

  Specifically, as shown in FIG. 2 to FIG. 4, the nozzle member 16 rises from the base portion 14 a of the nozzle 14 toward the axial direction, and has a generally bowl-shaped nozzle 14 having an open portion 22 on its side surface, Three (or two or more) inclined plane bottom portions 26a to 26c descending toward the central portion (near the axis of the nozzle 14) coupled to the base portion 14a of the nozzle 14 (inclined toward the rear in the axial direction). Between the inclined plane bottom portion 26, the annular inclined bottom portion 24 formed so as to encircle the outer direction from the nozzle base portion 14a, and the nozzle 14 via the inclined plane bottom portion 26 and the annular inclined bottom portion 24. It has a cylindrical wall portion 30 that rises toward the axially front side with a space 28 into which the storage cylinder portion 18 of the cap 20 can be inserted.

  As shown in FIG. 1, the nozzle member 16 axial center (axial direction) is indicated by a symbol “S”, the axial direction front is “SF”, and the rear is a symbol “SR”. Further, when the liquid pouring container is placed on the floor or tabletop, the mouth of the container body 10 faces upward, the spout 14b at the tip of the nozzle 14 of the nozzle member 16 faces upward, and the rear of the nozzle member 16 faces downward. When the liquid dispensing container is used, when the content liquid is poured into the cap 20, the spout 14 b ahead of the nozzle 14 faces obliquely downward from the side.

  The spout 14 b at the tip of the nozzle 14 is a port for pouring the liquid toward the outside such as the cap 20 and is a port for pouring the liquid from the refill container into the container body 10 through the nozzle member 16.

  As shown in FIG. 1, the cap 20 is formed in a cylindrical shape having a volume in which the storage cylinder portion 18 stores a necessary amount of content liquid (a measurement portion that is provided with a measurement scale if necessary), and a storage cylinder portion. A first flange portion 34 is formed on the outer wall 18 so as to cover the outer wall in a bowl shape and to be detachably attached to the cylindrical wall portion 30 of the nozzle member 16. Specifically, in the first flange portion 34, a screw portion (formed on the upper end of the cylindrical wall portion 30 of the nozzle member 16 on the inner surface of the open end portion (lower side in FIG. 1) of the storage cylinder portion 18. A screw portion (female screw) 34a is formed to be screwed into the male screw 30a. With this configuration, the cap 20 is attached to the upper end portion of the cylindrical wall portion 30 by screwing into the upper end portion of the cylindrical wall portion 30 by the screw portion 34 a of the cap 20.

  The outer wall surface of the cylindrical wall portion 30 of the nozzle member 16 is provided with a second flange portion 36 that covers the outer wall surface in a bowl shape and is attached to the mouth portion 12 of the container body 10. Specifically, the second flange portion 36 surrounds the outer wall surface of the cylindrical wall portion 30, and the peripheral wall hangs downward, and the distal end portion of the inner surface of the peripheral wall has a mouth portion of the container body 10. A screw part (female screw) 36a is formed which is screwed into a screw part (male screw, not shown) formed in FIG. The nozzle member 16 is attached to the mouth portion 12 of the container body 10 by screwing the mouth portion 12 of the container body 10 with the second flange portion 36.

  In the nozzle member 16, the storage cylinder portion 18 of the cap 20 is inserted into the space 28.

Moreover, the nozzle 14 of the nozzle member 16 is formed with an open portion 22 continuously from the spout 14b at the tip thereof. At the same time, as shown in FIGS. 2 to 3, the inclined plane bottom portion 26 is provided with an opening portion 26d for discharging the content liquid and replacing the air from the lowermost portion toward the inner wall surface of the nozzle 14. .
Further, a pair of guide walls 32 for controlling the liquid flow width rising in the vertical direction from the periphery of the opening 26d is formed on the inner wall surface of the nozzle 14 in parallel with the nozzle axis S. The opening 26d is formed in a deformed shape including a portion formed in a circle from the bottom to the nozzle 14 side and a portion formed in an oval shape including the bottom, so that no liquid remains in the bottom. Is. An opening 26d is elongated (26d1) from the inclined flat bottom 26 to the inside of the pair of guide walls 32 in the nozzle 14 inner wall surface in the liquid outflow direction (front) (see FIG. 3).

  The open end of the guide wall 32 is preferably about 4 to 10 mm, for example, at an appropriate interval that can be supported by fitting a spout of a refill container such as a pouch.

  Here, in the embodiment, as shown in FIGS. 2 and 5, the open width of the open portion 22 is formed wider than the open width of one guide wall 32. Specifically, as shown in FIG. 5, the width L1 of the side opening 22 of the nozzle 14 is set to be less than half (50% or less) of the circumferential length L0 of the nozzle 14 (L1 <L0 * 50%). .

Further, as shown in FIG. 3B, the annular inclined bottom portion 24 is located on the front side of the inclined flat bottom portion 26 (26c). It continues to the inclined plane bottom portion 26. In the liquid dispensing container of the embodiment, after the liquid is poured into the cap 20 and used again, the liquid that has flowed to the annular inclined bottom portion 24 flows in the direction of the step 38, and the inclined plane from the step 38. Since it flows to the bottom portion 26 (26c), even if the liquid contents accumulate on the inclined plane bottom portion 26 for some reason, it is blocked by the step 38, so that it can be reliably prevented from flowing back to the annular inclined bottom portion 24 side.
Further, the annular inclined bottom portion 24 is formed with a groove 40 on the inclined surface of the annular inclined bottom portion 24 for guiding the content liquid toward the inclined flat bottom portion 26 at a location adjacent to the outer wall surface of the nozzle 14.

  The main body container is formed by resin molding with a multilayer structure of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), or ethylene vinyl alcohol (EVOH) and polyethylene.

  The nozzle member 16 and the cap 20 can be formed of PE, PP, ABS, or the like.

  According to the liquid pouring container of the embodiment, the opening 26d for pouring the content liquid and replacing the air from the lowermost part toward the inner wall surface direction of the nozzle 14 is provided in the inclined flat bottom portion 26. Even when the diameter is large, the amount of liquid dispensed can be controlled by designing the opening area to be small. Further, since the inclined bottom surface portion 26 causes the residual liquid to flow toward the opening in each of the three (two or more) inclined bottom surface portions 26a to 26c, the liquid hardly remains in the nozzle 14.

  Further, by increasing the diameter of the nozzle 14, the volume of the annular space 28 around the nozzle 14 is reduced, and the probability that the liquid remains in this portion is reduced, so that the liquid dripping from the side of the nozzle 14 is less likely to occur.

Further, since the bottom portion 26 of the nozzle member 16 is composed of two or more inclined plane bottom portions 26a to 26c, the residual liquid flows toward the opening at each of the two or more inclined plane bottom portions 26a to 26c. Is difficult to remain.
Moreover, even if liquid remains in the nozzle member 16 because the width of the side surface opening portion 22 of the nozzle 14 is not more than half of the circumferential length of the nozzle 14 (50% or less), the opening portion 22 side of the nozzle 14 Most of the remaining liquid flows into the bowl-shaped nozzle 14 when it is poured out next, and does not cause dripping from the side of the nozzle 14.

  In addition, by increasing the diameter of the nozzle 14, when refilling with a pouch, the pouch spout can be easily placed against the side surface opening 22 of the nozzle 14 and fixed, so workability when refilling from the pouch is improved.

  Moreover, since the nozzle 14 exhibits a bowl shape having an open portion 22 on its side surface, the liquid can be poured from the open portion 22 and the refill workability is excellent.

  In addition, since the pair of guide walls 32 that control the liquid flow width provided on the inner wall surface of the nozzle 14 serve as a guide for supporting the pouch spout when refilling, it is possible to prevent the mouth of the pouch from shifting, so that refilling workability can be prevented. It is possible to achieve an excellent effect of improving.

  Since the pair of guide walls 32 for controlling the liquid flow width are provided on the inner wall surface of the nozzle 14 so as to rise in the vertical direction from the edge of the opening, the liquid guided to the guide wall 32 surely flows into the opening 26d. Can be made.

FIG. 6 is an explanatory diagram of a nozzle member 16A according to a modification of the embodiment.
In the embodiment shown in FIGS. 1 to 5, the inclined plane bottom portion 26 constituted by the three inclined plane bottom portions 26 a to 26 c of the nozzle member 16 has been described, but the number of surfaces of the inclined plane bottom portion is not limited to three. Like the nozzle member 16 </ b> A of the modification shown in FIG. 6, the inclined flat bottom portion 26 </ b> A configured by two inclined flat bottom portions 26 </ b> A <b> 1 to 26 </ b> A <b> 2 may be used. Of course, the number of inclined flat bottom portions may be four or more.
In this modified example, each inclined plane bottom portion 26A1 to 26A2 has one tangent line, which facilitates mold manufacture. Other configurations are the same as those of the liquid dispensing container of the embodiment.

  In order to confirm the operation and effect of the present invention, the inventor is in the upright state and the tilted state with respect to the cap of the conventional example and the caps of Examples 1 and 2 of the bottom shape and the nozzle side opening according to the present invention. Test the liquid flow etc. The results will be described with reference to FIGS.

  As shown in FIG. 7A, in the conventional example, in the nozzle member b having the nozzle a that is attached to the mouth portion 12 of the container main body 10 shown in FIG. Although formed, there is no guide wall, the bottom end of the bottom c of the nozzle base is located outside the nozzle a, and the opening d is formed in the nozzle a. Reference symbol e indicates a flange portion for mounting on the container mouth 12, and f indicates a cylindrical wall portion. A cap can be detachably mounted on the cylindrical wall portion f from above. Further, in Examples 1 and 2 shown in FIGS. 7B and 7C, in the above embodiment, the width (L1) of the open portion 22 of the nozzle 14 is 50% of the circumferential length (L0) of the nozzle 14 (open). Angle 180 degrees) and 30% (open angle 120 degrees). Others are the same as that of the said embodiment.

  The flow of the liquid remaining in the nozzle member when the container body is tilted upright after being tilted will be described with reference to FIG. In the conventional example, as shown in FIGS. 8A to 8B, after flowing around the outside of the nozzle a and accumulating at the bottom of the bottom c, it flows into the container body from the opening d. Further, in the first and second embodiments, as shown in FIGS. 8C to 8D and 8E to 8F, the container wraps around the outside of the nozzle 14 from the bottom of the bottom portions 26b and 26c through the opening 26d. It flows into the body. In the first and second embodiments, it can be understood that the flow path of the liquid flow is shorter than that of the conventional example, and the liquid flows quickly into the opening 26d.

  Further, referring to FIG. 9, the flow of the liquid remaining in the nozzle member at the time of pouring with the container body inclined to the side will be described. In the conventional example, as shown in FIGS. 9A to 9B, the liquid in the bottom portion c wraps around the outside (side) of the nozzle a and flows into the cylindrical wall portion f. On the other hand, in the first and second embodiments, as shown in FIGS. 9C to 9D and 9E to 9F, the liquid in the bottoms 26b and 26c is almost large in the bowl-shaped nozzle 14. The portion is received and can flow out from the nozzle 14, and there is little wraparound to the side of the nozzle 14, it is difficult for the liquid to drain from the cylindrical wall portion 30, and almost no side leakage occurs.

In the above-described conventional example, as shown in FIG. Further, also in the first and second embodiments, as shown in FIGS. 8C to 8D and 8E to 8F, the opening 26d is formed from the bottom of the bottom portions 26b and 26c by going around the outside of the nozzle 14 and extending from the bottom. Into the container body.
The performances of the conventional example and Examples 1 and 2 are compared and shown.
