Description

  The present invention relates to a liquid spout plug to be attached to a container, and more particularly to a liquid spout tap that enables selection of an appropriate state of pouring according to the application when the content liquid filled in the container is spouted. is there.

  2. Description of the Related Art A squeeze container having a squeeze container equipped with a dispensing switching cap that switches between a straight shape and a shower shape is known (see, for example, Patent Document 1).

The dispensing switching cap described in Patent Document 1 includes a fixed cap (1) and a head cap (2) that is rotatably fitted to the fixed cap (1). The wall (3) is provided with a “straight” liquid flow groove (7) extending across the top surface of the tube and both sides of the circumferential surface, and the “right” liquid flow groove (7) is sandwiched between A projecting cylinder (4) having recessed liquid passage grooves (8) and (9) and an engaging cylinder (6) are erected, and the head cap (2) is located at the center of the top plate (12). In addition, a pouring hole (13) connected to the “direct” liquid flow groove (7) and a large number of small holes (14) communicating to the “shower” liquid flow groove (9) are formed around it. In addition, on the peripheral edge of the top plate (12), a concave groove (16) for communication is formed on both sides of the inner peripheral surface that fits to the outer periphery of the protruding cylinder (4), and can be rotated around the fitting cylinder (6). Is mated to Fitting the peripheral wall (15) is vertically.
No. 5-42038

However, in the above-described prior art, the “straight” liquid flow groove (7) is recessed so as to cross the top surface of the protruding cylinder (4). Since a small hole for shower (14) cannot be formed in the top plate (12) of the head cap (2), a continuous shower could not be formed over the entire circumference.
Therefore, it is good when the object is large like a bathtub or the like, but when it is concentrated in a narrow area and distributed, the distribution is uneven.

  Further, in order to prevent the head cap (2) from moving loose during use, an engagement protrusion is provided on the outer periphery of the fitting tube (6) to engage the head cap (2) with the fixed cap (1). Therefore, the rotating operation of the head cap (2) could not be lightened.

  In consideration of the above circumstances, the present invention is capable of uniformly ejecting even within a narrow range, making it easy to rotate the rotating body and locking it at a predetermined position. An object of the present invention is to provide a liquid pouring tap that can be switched between shower-like pouring.

Next, usage modes and effects of the container of this embodiment will be described.
After filling the container A with the content liquid, the stopper body B is attached to the mouth tube portion 1 of the container A, and then the rotating body C is rotatably attached to the stopper body B.
By covering the cap body B with the overcap D, a liquid dispensing container equipped with a liquid dispensing plug can be obtained.

When using the liquid dispensing container, the overcap D is removed from the plug body B and the lid is opened.
When it is desired to use the liquid pouring tap in a single straight shape, the rotating body C is rotated, and the display 43a on the outer peripheral wall 33 of the rotating body C is displayed on the plug body B as shown in FIG. Align with the instruction unit 15 provided in the unit 11.
At that time, the engaging recess 44 a provided on the inner periphery of the outer peripheral wall 33 of the rotating body C is engaged with the locking plate 25 of the plug body B.
And the notch part 26 provided in the shaft cylinder 22 of the plug body B and the notch part 41 provided on the inner periphery of the inner cylinder 34 of the rotating body C are superposed, and the straight communication grooves 26a and 41a are connected to each other. The flow path is formed.

By tilting the entire container and pressing the body portion 3 of the container A, the content liquid passes through the communication hole 24 provided in the top wall 10 of the stopper body B, and the top wall 10 upper surface, the shaft tube 22, the outer tube 23, Enter the space.
Next, the content liquid passes through the straight communication grooves 26 a and 41 a formed between the notch portion 26 of the plug body B and the notch portion 41 of the rotating body C, and from the straight pouring hole 37 of the rotating body C. It is poured out straight.

When it is desired to use the discharge state of the liquid discharge plug in the form of several showers, the rotating body C is rotated, and the display 43b or the display 43d on the outer peripheral wall 33 of the rotating body C is plugged as shown in FIG. Match with the indicator 15 provided on the step 11 of the main body B.
At that time, the engaging recess 44 b or the engaging recess 44 d provided on the inner periphery of the outer peripheral wall 33 of the rotating body C is engaged with the locking plate 25 of the plug body B.
And the notch part 27 provided in the outer periphery cylinder 23 of the stopper main body B and the notch part 42 provided in the outer periphery of the outer cylinder 35 of the rotating body C are superposed, and the communication grooves 27a and 42a for showers are connected to form a liquid.

Therefore, since the content liquid is not poured out even if the whole container is tilted and the container A is pressed, the liquid pouring tap is closed.

  If you want to stop using the liquid dispensing container and keep it, keep the liquid dispensing plug in the above-mentioned closed state, cover the cap body B with the overcap D, and seal the liquid dispensing plug. As a result, it is possible to prevent the liquid attached to the pouring cylinder 38 and the shower pouring hole 39 of the rotating body C from drying and solidifying, and blocking the hole. Invasion of various bacteria can be prevented by not touching.

  Since the engaging recesses 44a, 44b, 44c, and 44d are provided on the inner periphery of the outer peripheral wall 33 of the locking plate 25 and the rotating body C in the stopper main body B, when the rotating body C is rotated when using the liquid discharge stopper. By engaging the engaging recesses 44a, 44b, 44c, 44d and the locking plate 25, a click motion is given, so that the confirmation of the dispensing state can be assured to the user. When the liquid is poured out, it is possible to prevent the rotating body C from rotating carelessly and changing the pouring state during the pouring.

In the above-described embodiment, the setting of the discharge state of the liquid discharge plug is straight on the display 43a of the rotating body C, shower on the display 43b or 43d, and closed on the display unit 43c. If the display setting of the display unit 43 is changed, and the cutout portions are provided on the inner circumference of the inner cylinder 34 and the outer circumference of the outer cylinder 35 of the rotating body C, the setting of the dispensing state can be changed. .
The setting of the pouring state of the liquid pouring tap of the present invention is not limited to the above embodiment.

  In the above-described embodiment, the location where the liquid discharge tap is switched at 90 ° intervals is set by the rotating body C, but the liquid discharge tap is discharged at a desired angle, for example, 120 ° intervals. Accordingly, the cutout portion 27 of the outer cylinder 23 with respect to the cutout portion 26 of the shaft cylinder 22 of the plug main body B, and the inner circumference of the inner cylinder 34 and the outer circumference of the outer cylinder 35 of the rotating body C are associated. By setting the position of the part, it is possible to change the place where the dispensing state is switched to a desired angle.

Moreover, if a notch part is provided at the same angle on the inner periphery of the inner cylinder 34 and the outer periphery of the outer cylinder 35 of the rotating body C, the content liquid can be simultaneously poured out from all the dispensing holes.
The angle setting and the pouring situation of the switching position of the pouring state of the liquid pouring tap of the present invention are not limited to the above embodiment.

The liquid pouring tap of the liquid pouring container of the present invention is constituted by a plug body and a rotating body, and by rotating the rotating body, the liquid pouring state can be easily changed and poured out. By engaging the locking plate and the locking recess, it is possible to reliably maintain the pouring state, and it can be used more easily and safely than the conventional one.
