Description

[0001]
[Industrial application fields]
The present invention relates to a structure of a dispensing cap suitable for dispensing a content liquid having a relatively high viscosity of about 25 cps in a normal temperature atmosphere.
[0002]
[Prior art]
A cap body with a top tube shape that is tightly assembled to the mouth of the container body, and a pouring cylinder is erected on the top wall, and is integrally hinged to the cap body so as to be openable and closable. In a pouring cap composed of a top cover provided with a fitting tube that is tightly fitted into the tube and seals the pouring tube, the pouring tube is provided for the purpose of improving the content of the liquid. The cylindrical cylindrical piece standing on the top surface of the top wall and the flange piece protruding outward from the upper end of the outer peripheral surface of the cylindrical piece.
[0003]
In the conventional pouring cap, the width of the pouring piece is set to about 0.6 mm in consideration of the release from the molding die of the pouring cap that is integrally formed. In general, the height from the lower surface to the upper surface of the top wall is set to about 2 mm, which is as small as possible, within a range in which the guided liquid can be guided.
[0004]
[Problems to be solved by the invention]
However, in the above-described prior art, when the viscosity of the content liquid to be poured out is low, a relatively good liquid breakage can be obtained, but the viscosity in a room temperature atmosphere such as hair treatment oil When a relatively high content liquid of about 25 cps is poured out, after the content liquid is poured out, a part of the content liquid remaining on the outer periphery of the piece wraps around the bottom of the piece and causes dripping. There was a problem.
[0005]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and even in the case of a content liquid having a relatively high viscosity of about 25 cps in a normal temperature atmosphere, the liquid in the dispensing cylinder can be removed. It is an object of the present invention to prevent the occurrence of discomfort caused by dripping and the occurrence of dirt.
[0006]
[Means for Solving the Problems]
The means of the present invention for solving the above technical problem is:
The cap body is tightly assembled to the mouthpiece of the container body, and the pouring tube is erected on the top wall. The cap body is hinged to the cap body so that it can be freely opened and closed. A pouring cap used for a relatively high liquid having a viscosity of about 25 cps, which is composed of an upper lid provided with a fitting tube that is tightly fitted to seal the pouring tube;
The cap body's pouring tube is composed of a cylindrical tube piece standing from the top wall and a flange piece projecting outward from the upper end of the outer peripheral surface of the tube piece;
The width of the spout of the pipe barrel of the cap body shall be 2 mm or more, and the height from the top wall top surface to the bottom surface of the scissors shall be 5 mm or more.
Surrounding the opening at the bottom surface of the top wall of the pouring passage formed by the pouring tube of the cap body, a cylindrical rectifying tube is suspended,
It is in.
[0007]
[Action]
The container body containing the liquid with the dispensing cap assembled must be tightly assembled with the cap body of the dispensing cap when the dispensing cap is closed, and the dispensing cylinder of the cap body. Is hermetically sealed by the fitting tube of the upper lid.
[0008]
From this sealed state, the upper lid is pivoted about the hinge to disengage the fitting cylinder from the dispensing cylinder of the cap body, the dispensing cylinder and the container body are opened, and the container body is tilted in the desired direction. The content liquid is poured out.
[0009]
When the content liquid is dispensed, the flow of the content liquid is rectified into a substantially constant form by the rectifying cylinder before flowing into the extraction passage formed by the extraction cylinder. The flow form of the content liquid is constant and stable.
[0010]
The liquid that has flowed into the dispensing cylinder passes from the inner surface of the dispensing cylinder through the upper surface of the rod piece, detaches from the outer peripheral edge of the rod piece, and is dispensed. At the end of the pouring operation after returning the inclination of the liquid, the liquid contents inevitably remain in the form of droplets on the outer peripheral edge of the flange due to the surface tension of the liquid contents.
[0011]
However, the surface tension of the content liquid which is located on the upper surface of the rod piece and is about to flow down into the cylinder piece acts as a pulling force on the drop-like content liquid which is to remain on the outer peripheral edge of the rod piece, and this The pulling force, which is located on the top surface of the scabbard and acts on the drop-shaped content liquid that is about to flow down into the outer periphery of the slab, is 2 mm or more. Therefore, the droplet-like content liquid that tends to remain on the outer peripheral edge of the sepal piece is attracted to the content liquid that is located on the upper surface of the sepal piece and flows down into the cylindrical piece, and is integrated into the cylindrical piece. It does not flow into the inside of the container body, i.e., the container body.
[0012]
At the end of the dispensing operation of the content liquid, the drop-shaped content liquid that remains on the outer periphery of the sepal is in a relatively long state at the moment when it is separated from the poured content liquid. Due to the effect of the surface tension accompanying the reaction of the drop, it becomes drooping faster than it becomes round like a drop, but since the height of the bottom surface of the scissors and the top surface of the top wall is more than 5mm, immediately after this drooping The content liquid remaining on the top of the piece does not come into contact with the top surface of the top wall, and is surely rounded like a drop around the outer periphery of the piece.
[0013]
In addition, the movement of the content liquid which is to remain on the outer periphery of the flange at the end of the content liquid pouring operation is stable because the content liquid pouring form is stabilized by the action of the rectifying cylinder. , Always constant.
[0014]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is an overall longitudinal sectional view showing an opened state of an embodiment of the present invention, and a cap body 1 closely screwed into a mouthpiece of a container body 3 and a hinge 6 having a mirror hinge structure on the cap body 1. And an upper lid 2 that are connected to each other so as to be freely openable and closable, and are integrally formed of synthetic resin.
[0015]
The cap main body 1 has a pouring cylinder 5 composed of a cylindrical piece 8 and a flange piece 9 on a slightly forward side of the top wall 4 of the top cylindrical body that is externally screwed into the mouthpiece of the container main body 3. And a cylindrical piece of rectifying cylinder 10 is suspended from the lower surface of the top wall 4 where the extraction passage formed by the extraction tube 5 is opened, surrounding the opening of the extraction passage. .
[0016]
The pouring cylinder 5 of the cap body 1 has a width l of the flange piece 9 set to 2 mm, and the height of the cylinder piece 8 is set to a height h from the lower surface of the flange piece 9 to the upper surface of the top wall 4. Is set to a value of 5 mm, and the inner peripheral surface of the cylinder piece 8 is a tapered surface whose diameter is increased upward, and the insertion operation of the insertion cylinder 7 of the upper lid 2 at the time of rotation closing is smoothly achieved. To be.
[0017]
The rectifying cylinder 10 of the cap body 1 has an inner peripheral surface of the inner peripheral surface of the cylindrical piece 8 via a step portion that acts to maintain a close fit with the cylindrical piece 8 of the inserted cylinder 7 of the upper lid 2 when closed. Is provided with a height of 5.1 mm.
[0018]
The upper lid 2 is integrally connected to the rear upper end of the cap body 1 via a hinge 6 having a mirror hinge structure, and is a narrow cylindrical piece-like insertion tube slightly forward of the inner surface of the top wall of the deep dish-shaped body portion. 7, and the height of the insertion cylinder 7 is such that when the insertion cylinder 7 is tightly fitted into the extraction cylinder 5 to the insertion limit, the protrusion provided around the outer peripheral surface of the tip is The height is set to a level at which a step formed between the inner peripheral surface of 8 and the inner peripheral surface of the rectifying cylinder 10 is locked (see FIG. 3) from below.
[0019]
As a result of storing the hair treatment oil having a viscosity of 25 cps in a normal temperature atmosphere in the container body 3 assembled with the dispensing cap of the present embodiment and testing whether or not dripping occurs, no dripping occurs. Was confirmed.
[0020]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
Since the width of the flange that constitutes the dispensing cylinder of the cap body is set to 2 mm or more, the droplet upper surface and the inner circumferential surface of the cylinder are protected against the drop-like content liquid remaining on the outer periphery of the flange. A strong tensile force associated with the surface tension is applied from the content liquid that is about to flow back into the container body, so that the droplet-shaped content liquid that remains on the outer peripheral edge of the sepal piece is surely contained in the container body. It is possible to eliminate the content liquid remaining on the outer peripheral edge of the flange piece.
[0021]
Since the height from the bottom surface of the pouring piece to the top surface of the top wall of the pouring tube of the cap body is set to 5 mm or more, even a relatively high liquid having a viscosity of about 25 cps remains attached to the outer periphery of the sepal piece when the liquid runs out. It is possible to reliably prevent the content liquid from coming into contact with the top surface of the top wall in the state where the liquid is in the drooping posture, and thus it is possible to reliably prevent the dripping that occurs when the liquid runs out.
[0022]
Since a flow straightening cylinder is provided at the inlet of the extraction passage formed by the extraction cylinder, the flow of the discharged content liquid is always constant and stable, which causes pulsation or turbulence of the extracted content liquid. It is possible to reliably prevent the occurrence of liquid dripping due to instability of the liquid running state due to non-rectification such as.
[0023]
In this way, it is possible to achieve a good drainage of the content liquid, and it is possible to reliably prevent the liquid dripping and the remaining of the content liquid on the outer peripheral edge of the flank, so that the container may become dirty due to dripping or dirty Generation | occurrence | production of a feeling can be prevented beforehand and the favorable usability | use_condition of a container can be obtained over a long period of time.
