Description

  The present invention relates to a pouring container, and more particularly, to a pouring container in which a pouring cap having a pouring nozzle is attached to a mouth portion of a container main body.

  As a dispensing container having a dispensing cap equipped with a dispensing nozzle at the mouth of the container body, for example, a container with a measuring cap used in combination with a measuring cap is known (see, for example, Patent Document 1 and Patent Document 2). ). For these dispensing containers, remove the measuring cap that covers the dispensing nozzle of the dispensing cap, remove the measurement liquid from the dispensing cap via the dispensing nozzle, and then weigh it. The content liquid is put into a dispensing part such as a washing machine. In addition, if the content liquid stored in these dispensing containers runs out or decreases, for example, refill the contents liquid from a bag-like container for refilling as appropriate, and the dispensing container itself can be used for a long time without being discarded. can do.

  On the other hand, in these dispensing containers, if the container body is tilted sharply when the content liquid is dispensed, it overflows from the liquid recovery slit provided in the dispensing nozzle, and the content liquid overflows outside the dispensing nozzle. May come out. In particular, when the viscosity of the content liquid increases, the flow speed of the content liquid flowing down along the pouring nozzle is faster than the flow speed of the content liquid flowing out from the container body to the pouring nozzle through the pouring outlet communicating with the pouring nozzle. Becomes too small, and the liquid content tends to overflow to the outside of the pouring nozzle.

  For this reason, even if the container body is tilted sharply when the content liquid is poured out, the dispensing container prevents the liquid content from jumping out of the dispensing nozzle or overflowing outside the dispensing nozzle. Has also been developed (see, for example, Patent Document 3). In the pouring container of Patent Document 3, an inclined wall extending downward to almost the center of the pouring port is provided at the lowermost part of the inclined bottom plate of the pouring cap, so that the pouring port is shielded to almost half and the container body is abruptly cut. Even when it is tilted, the content liquid does not jump out vigorously.

  However, in the dispensing container of Patent Document 3, it is possible to prevent the content liquid from jumping out vigorously. It is difficult to dispense a predetermined amount in a stable state. For example, when the viscosity of the contents is high and the fluidity is low, when a small amount of liquid detergent is applied directly from the dispensing nozzle to a place where laundry is conspicuous without using a measuring cap, It becomes difficult to put out. In addition, if it is tilted greatly in order to pour it quickly, it may be clogged or popped out by the inclined wall at the bottom of the pouring nozzle, and it is difficult to control the pouring amount depending on the physical properties of the content liquid. Therefore, it is convenient if the liquid detergent can be discharged in a stable state while controlling the amount of liquid detergent.

  When replenishing the content liquid, the present invention allows the content liquid to smoothly flow into the container body through the spout, and when dispensing the content liquid, the content liquid is discharged from the dispensing nozzle. An object of the present invention is to provide a dispensing container that can effectively avoid overflowing to the outside and can discharge the content liquid from a dispensing nozzle in a stable state while controlling the dispensing amount. .

  In the present invention, a pouring cap having a pouring nozzle is attached to the mouth portion of the container body, and the content liquid that has flowed out of the pouring outlet to the pouring nozzle by tilting the container body is disposed in the pouring nozzle. The dispensing cap is poured out from the tip of the container, and the dispensing cap includes an inner cylindrical wall disposed along the inner peripheral surface of the mouth portion of the container main body, and is provided at the lower end of the inner cylindrical wall. The pouring nozzle is provided so as to stand upright from the bottom wall and spaced from the inner cylinder wall, and the pouring port is provided on the bottom wall of the pouring nozzle. An opening is formed in the inner region, and the dispensing nozzle has a concave cross-sectional shape with an opening on the side opposite to the tilting direction when the content liquid is poured out. An overhanging peripheral wall is interposed between the opening edge and the base end of the pouring nozzle. By providing a dispensing container provided Te is obtained by achieving the above object.

  According to the dispensing container of the present invention, when the content liquid is replenished, the content liquid can smoothly flow into the container body through the spout, and when the content liquid is dispensed, The liquid can be effectively avoided from overflowing to the outside of the pouring nozzle, and the content liquid can be poured out from the pouring nozzle in a stable state while controlling the pouring amount.

In a state where the open side end portion is disposed on the lowermost surface portion 18a, the inner wall 17 is spaced from the inner cylindrical wall 17 and is provided in a region straddling the inclined side inclined surface portion 18b and the lowermost surface portion 18a. Further, the pouring nozzle 14 is erected substantially perpendicularly to the lowermost surface portion 18 a of the bottom wall 18 with the upper portion protruding upward from the inner cylinder wall 17. The upper part of the pouring nozzle 14 projecting upward from the inner cylinder wall 17 has a substantially semicircular shape when viewed from the side, with the height of the side wall portion having a substantially U-shaped cross section gradually reduced toward the tip side. (See FIG. 3A). The dispensing nozzle 14 is preferably approximately 15 mm to 35 mm in length in the tilt direction X of the substantially U-shaped cross-section at the base end portion 14a, and the length in the width direction perpendicular to the tilt direction X is It is preferable that it is 10-30 mm in the position where 16 becomes the maximum width.

  In this embodiment, as shown in FIGS. 2 and 3C, the spout 16 is formed in the inner region of the base end portion 14 a of the spout nozzle 14 having a substantially U-shaped cross section on the bottom wall 18. Yes. That is, the spout 16 is formed in a substantially semi-oval shape having a shape substantially along the shape of the base end portion 14a of the spout nozzle 14 in the region of the tilt side inclined surface portion 18b of the bottom wall 18. Continuing from the edge on the opposite side to the tilting direction X of the substantially semi-ellipse-shaped part, a notch 16b for air feeding when the content liquid is poured out is formed in a rectangular shape. The cut-in portion 16b for feeding air is provided so as to bite into the lowermost surface portion 18a of the bottom wall 18. That is, when the container body 11 is in the upright state, the substantially semi-oval portion of the spout 16 is formed in the inclined side inclined surface portion 18b, and only the portion where the notch portion 16b is connected to the substantially semi-oval portion is the inclined surface portion.

  Further, in the present embodiment, the entire spout 16 including the notch 16b is formed in the bottom wall 18 in the inner region of the base end portion 14a of the spout nozzle 14 having a substantially U-shaped cross section. An overhanging peripheral wall 19 is interposed between the opening edge 16 a of the spout 16 and the base end portion 14 a of the spout nozzle 14.

  The overhanging peripheral wall 19 is a part provided as a part of the bottom wall 18 so as to project from the base end portion 14 a of the pouring nozzle 14 toward the inner pouring port 16 in a plate shape. Since the protruding peripheral wall 19 is interposed between the opening edge portion 16a of the spout 16 and the base end portion 14a of the spout nozzle 14, the spout 16 has a base of the spout nozzle 14 over its entire circumference. An opening shape that is slightly smaller than the shape of the inner region of the end portion 14a is provided.

  Here, the overhanging width b (see FIG. 3C) of the overhanging peripheral wall 19 at least in the tilting direction X side of the spout 16 is preferably 0.5 to 5 mm, particularly 1 to 4 mm. . If it is within this range, it can be prevented from coming out regardless of the liquidity of the content liquid, and a small amount of discharge can be easily controlled. If the width b of the overhanging peripheral wall 19 is too small, the container will be easily inclined in a large amount, particularly when the content liquid is low in viscosity and easily flows out. On the other hand, if it is too large, it will be difficult to pop out if the container is tilted slightly, but it will tend to pop out if it is tilted rapidly. In this embodiment, the overhanging peripheral wall 19 is provided over the substantially semi-oval portion of the spout 16, but is partially provided at the U-shaped tip (tilt side) and both side edges. May be.

  In this embodiment, the weighing cap 15 that covers the dispensing nozzle 14 of the dispensing cap 13 and is attached to the neck 12 of the container body 11 is a molded product made of synthetic resin, and as shown in FIG. It consists of a cylinder part 24 and a skirt-like mounting part 25 that projects outwardly in a skirt shape from the outer peripheral surface of the intermediate part of the measuring cylinder part 24 and is integrally molded. A female threaded ridge 26 is provided on the inner peripheral surface of the skirt-shaped mounting portion 25. By screwing the female threaded ridge 26 with a male threaded ridge 23 provided on the outer peripheral surface of the mouthpiece 12 of the container body 11, the measuring cap 15 has the dispensing nozzle 14 disposed inside the measuring tube portion 24. In the housed state, the container body 11 is detachably attached to the mouth portion 12. An annular seal portion 25 b is formed on the inner surface side of the top surface portion 25 a of the skirt-shaped mounting portion 25, and the inside of the container body is hermetically sealed by contacting the annular locking rib 17 b at the upper end portion of the inner cylindrical wall 17. The Moreover, you may form a knurl as needed in the outer surface of the cylindrical wall of the skirt-shaped mounting part 25 as shown in the figure.

  After the metering cap 15 is removed from the neck 12 of the container body 11 and the opening is turned upside down, the content liquid is injected from the dispensing nozzle 14 of the dispensing cap 13 and weighed. A predetermined amount of the content liquid can be poured out into a dispensing part such as a washing machine. In addition, when the opening portion is mounted again on the neck portion 12 of the container main body 11, the portion on the opening side with respect to the skirt-shaped mounting portion 25 of the measuring tube portion 24 is used as the liquid return portion 24a. The cap 13 is inserted and disposed in the space between the inner cylinder wall 17 and the dispensing nozzle 14. As a result, the content liquid remaining in the measuring cylinder portion 24 can be smoothly collected inside the container body 11 through the opening portion of the pouring nozzle 14 and the pouring port 16.

  In the present embodiment, as shown in FIG. 4, the measuring tube portion 24 of the measuring cap 15 has a chevron-shaped cross section including a ridge line portion 28a and a pair of flat portions 28b on both sides of the peripheral surface. A shaped portion 28 is provided. By disposing the chevron-shaped cross-section portion 28 below and inclining the measuring cap 15, the content liquid in the measuring tube portion 24 can be poured out from the opening portion by small amount through the ridge line portion 28a. As a result, it is possible to easily perform partial application of the content liquid to clothes or the like using the tip portion of the ridge line portion 28a. A measurement scale is drawn on the plane portion 28b.

  Furthermore, the liquid return part 24a side and the measurement part 24b side of the measurement cylinder part 24 sandwiching the skirt-like attachment part 25 protrude from the skirt-like attachment part 25 in the axial direction, respectively, and the external shape on the liquid return part 24a side and the measurement The outer shape on the part 24b side is formed substantially the same. Therefore, the user of the cap can recognize the position of the dispensing nozzle 14 at a glance even when the measuring cap 15 is attached to the container body 11.

  And according to the pouring container 10 of the present embodiment having the above-described configuration, when the content liquid is poured out, the content liquid can be effectively avoided from overflowing to the outside of the pouring nozzle 14, When replenishing the content liquid, the content liquid can be smoothly flowed into the container main body 11 through the spout 16 and the content liquid is stably dispensed in a small amount while controlling the amount dispensed. 14 can be dispensed.

  That is, according to the pouring container 10 of the present embodiment, the pouring outlet 16 is formed in the inner region of the pouring nozzle 14 in the bottom wall 18, and the opening edge 16 a of the pouring outlet 16 and the pouring nozzle 14 are formed. Since the projecting peripheral wall 19 is interposed between the base end portion 14a of the liquid and the base end portion 14a, the content liquid flowing out from the container body 11 to the pouring nozzle 14 through the pouring port 16 is discharged from the pouring port 16. However, it flows down to the front end side of the discharge nozzle 14 through the flow path formed by the pouring nozzle 14 having a substantially U-shaped cross section (concave cross section). Accordingly, for example, when the content liquid is dispensed, the container body 11 is abruptly tilted, and the content liquid flows out from the entire spout 16 to the dispensing nozzle 14 at once, or the content liquid is, for example, 150 to 4000 mPa · s ( It is a liquid having a high viscosity of about 20 ° C., particularly 400 to 2000 mPa · s (20 ° C.), and the flow velocity along the pouring nozzle 14 is too small compared to the flow velocity from the pouring port 16. Even in this case, the flow passage cross section by the pouring nozzle 14 becomes larger than the pouring port 16, so that the content liquid stays in the pouring nozzle 14 and the content liquid overflows outside the pouring nozzle 14. Can be avoided.

  Moreover, according to the pouring container 10 of the present embodiment, the pouring nozzle 14 has a substantially U-shaped cross section (concave cross section) with an opening on the side opposite to the tilting direction X. 16 has an opening shape having a considerable size along the shape of the base end portion 14a of the pouring nozzle 14 having a substantially U-shaped cross section, so that the pouring is widely opened as shown in FIG. From the open side of the nozzle 14, for example, the refilling operation of the content liquid using the refillable bag-like container 27 can be performed easily and smoothly.

  Furthermore, according to the pouring container 10 of the present embodiment, since the overhanging peripheral wall 19 having an overhang width b of about 0.5 to 5 mm is provided at least on the portion of the pouring outlet 16 on the tilting direction X side, When the content liquid flows out from 16 to the flow path by the pouring nozzle 14, the overhanging peripheral wall 19 functions as an overflow dam, and the content liquid once flows over the overhanging peripheral wall 19 and then flows out to the pouring nozzle 14. As a result, it becomes possible to easily control the amount of dispensing by adjusting the size of tilting the container body 11 in the tilting direction X, and in particular, even when dispensing the content liquid little by little, A desired amount of the content liquid can be poured out from the dispensing nozzle 14 in a stable state.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the pouring container does not necessarily need to cover the pouring cap and be detachably mounted with the measuring cap. In addition, the pouring cap may be attached to the inside of the mouth portion of the container body in a fitting manner, or may be attached to the outside of the mouth portion of the container body in a screwing manner. Furthermore, the content liquid accommodated in the container body and poured out from the dispensing nozzle may have a low viscosity as well as a high viscosity. In addition to the liquid detergent for clothing, the content liquid may be other various liquids such as a softener, a bleaching agent, a dish detergent, a bath agent, and a residential detergent. The dispensing nozzle may have a concave cross-sectional shape other than the substantially U-shaped cross-sectional shape.
