Description

[0001]
[Industrial application fields]
The present invention includes a cap main body projecting a pour tube from the top wall, and an upper lid projecting a fitting tube that is hinged to the cap main body and fits in the pour tube and closes the pour tube. It is related to the pouring cap composed of
[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 tube piece is provided upright on the top surface of the top wall, and the flange piece protrudes outward from the upper end of the outer peripheral surface of the tube piece.
[0003]
In the conventional dispensing cap, the width of the flange is set to about 0.6 mm in consideration of the release of the integrally formed dispensing cap from the molding die. The height from the lower surface to the upper surface of the top wall is within a range that can exert a guide action on the liquid to be dispensed in consideration of the release from the molding die and the opening / closing rotation of the upper lid. Therefore, it is generally set to about 2 mm as small as possible.
[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, immediately after the content liquid is poured out, a part of the content liquid remaining in the form of droplets on the outer peripheral edge of the flange piece does not return to the container body. There was a problem that it remained and flowed to the lower side of this piece to cause dripping.
[0005]
Also, when the liquid runs out immediately after the pouring operation, the content liquid portion adhering to the outer peripheral edge of the rod piece in a slender state is recoiled before it rounds into a drop shape, causing the outer peripheral surface or top of the cylinder piece to recoil. There was a problem that liquid dripping occurred in direct contact with the upper surface of the wall.
[0006]
Furthermore, in order to reliably and firmly achieve sealing of the cap main body extraction tube by the upper cover insertion tube, the height of the upper cover insertion tube is set to a size that can penetrate into the depth of the cap main body injection tube, There is a problem that the height of the insertion cylinder tends to obstruct the insertion operation of the insertion cylinder into the extraction cylinder, and the closing operation of the extraction cap cannot be achieved smoothly.
[0007]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and even when the content liquid has a relatively high viscosity of about 25 cps in a normal temperature atmosphere, the liquid runs out at the time of dispensing. The technical challenge is to achieve a strong recovery of the liquid remaining in the dispensing cylinder into the container body, thus preventing discomfort during use due to dripping and the occurrence of dirt. For the purpose.
[0008]
[Means for Solving the Problems]
The means of the present invention for solving the above technical problem is:
A cap body that is assembled at the mouth of the container body, and a pour tube is erected from the top wall, and is connected to the cap body by a hinge that can be opened and closed, and is tightly fitted into the pour tube of the cap body in a closed state. And an upper cap provided with a fitting tube that projects the sealing tube, and is used for a relatively high liquid having a viscosity of about 25 cps ,
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 flange is 2 mm or more within a range in which the insertion tube of the upper lid can be attached to and detached from the extraction tube,
It is in.
[0009]
In addition, the height from the upper surface of the top wall of the cap body to the bottom surface of the collar piece is set to 5 mm or more within a range in which the fitting cylinder of the upper lid can be attached to and detached from the dispensing cylinder of the cap body.
[0010]
It is effective to stand the pouring tube of the cap body upright on the end portion on the side of the top wall opposite to the side on which the hinge is provided.
[0011]
[Action]
The container body that contains the contents liquid by assembling the dispensing cap must be tightly assembled with the cap body in the closed state of the dispensing cap, and the dispensing cylinder of the cap body. Is hermetically sealed by the fitting tube of the upper lid.
[0012]
From this sealed state, the upper lid is rotated about the hinge, the fitting cylinder of the upper lid is detached from the dispensing cylinder of the cap body, the dispensing cylinder and the container body are released, and the container body is in the desired direction ( In general, the content liquid is poured by inclining in the direction opposite to the side where the hinge is located.
[0013]
The liquid to be poured that has flowed from the inside of the container body into the dispensing cylinder of the cap body is separated from the outer peripheral edge of the rod piece through the cylindrical piece inner surface of the dispensing cylinder, passes through the upper surface of the rod piece, and is dispensed. However, at the end of the pouring operation after returning the inclination of the container body, due to the action of the surface tension of the content liquid, a part of the content liquid adheres to the outer peripheral edge of the flange piece at the same time as the liquid runs out. .
[0014]
The surface tension of the content liquid returning to flow into the cylinder piece from the upper surface of the flange piece acts as a drawing force on the content liquid adhering to the outer peripheral edge of the flange piece.
[0015]
The surface tension that the content liquid on the top surface of the strip acts as a pulling force on the content liquid remaining on the outer peripheral edge of the strip is sufficiently strong because the width of the strip is as large as 2 mm or more. The content liquid remaining on the outer peripheral edge of the piece is attracted to the content liquid on the upper surface of the flange piece, and reliably flows back into the cylinder piece, that is, into the container body.
[0016]
In addition, at the moment when the liquid is completely discharged after the dispensing operation is completed, the content liquid adhering to the outer peripheral edge of the rod piece becomes a relatively elongated state immediately before it becomes a drop, and the cylinder remains in a suspended state due to the reaction of the liquid Although it swings and displaces to one side, the height from the bottom surface of the rod piece to the top surface of the top wall is 5 mm or more, so it does not directly contact the top surface of the top wall, and from the outer periphery edge of the rod piece to the outer peripheral surface of the cylinder piece Since the distance is as large as 2 mm or more, it does not come into direct contact with the outer peripheral surface of the cylinder piece, and is surely rounded in the form of droplets on the outer peripheral edge of the rod piece.
[0017]
The width of the flange and the height from the top wall top surface to the bottom surface of the flange are regulated within a range in which the insertion tube of the upper lid can be attached to and detached from the extraction tube of the cap body, so that the hinge body is coupled to the cap body. The opening / closing rotation operation by the upper lid is smoothly achieved without any trouble.
[0018]
In particular, by providing the pouring tube at the end on the top wall side opposite to the side on which the hinge is provided, the relative displacement of the fitting of the upper lid with respect to the pouring tube becomes linear in the vertical direction. This makes it easy to attach and detach the insertion tube with respect to the dispensing tube, and accordingly, it is possible to increase the width of the flange and the increase in height from the top wall top surface to the bottom surface of the flange. It becomes.

【Example】
An embodiment of the present invention will be described with reference to the drawings.
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.
[0020]
The cap main body 1 has a dispensing cylinder 5 composed of a cylindrical piece 8 and a flange piece 9 slightly forward of the upper surface of the top wall 4 of the top cylindrical body that is externally screwed into the mouthpiece of the container main body 3. It is configured upright.
[0021]
The pouring cylinder 5 of the cap body 1 has an outer diameter of the flange piece 9 of 8.5 mm and an outer diameter of the cylinder piece 8 of 4.5 mm, thereby setting the width l of the flange piece 9 to 2 mm. The height h from the top surface of the top wall 4 to the bottom surface of the flange piece 9 is 5 mm.
[0022]
The inner peripheral surface of the tube piece 8 of the dispensing cylinder 5 is a tapered surface whose diameter is increased upward, and the fitting and unloading operation of the fitting cylinder 7 of the upper lid 2 with respect to the dispensing cylinder 5 during the opening / closing rotation operation is smooth. To be achieved.
[0023]
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 fitting cylinder 7 is set to a value for fitting (see FIG. 3) to the deep part of the dispensing cylinder 5 when the upper lid 2 is closed.
[0024]
As a result of storing hair treatment oil having a viscosity of 25 cps in a normal temperature atmosphere in the container body 3 to which the pouring cap of the present embodiment is assembled, and testing whether or not dripping occurs, no dripping occurs. Was confirmed.
[0025]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
Since the width of the spigot constituting the dispensing cylinder of the cap body is set to 2 mm or more, when the liquid runs out after the content liquid has been poured out, it is possible to ensure that the content liquid that will remain in the form of droplets on the outer peripheral edge of the spear The flow can be returned to the inside of the main body, so that no dripping occurs due to the content liquid remaining in the form of droplets on the outer peripheral edge of the flange.
[0026]
Since the width of the flange is set to 2 mm or more and the height from the top wall upper surface to the bottom surface of the flange is set to 5 mm or more, even if the liquid has a relatively high viscosity of about 25 cps, It is possible to reliably prevent the content liquid adhering to the edge from coming into direct contact with the top wall top surface or the outer peripheral surface of the cylinder piece, thereby reliably preventing the occurrence of liquid dripping when the liquid runs out. It is possible to obtain a sanitary usage condition of the container body.
[0027]
By providing the extraction tube at the end on the top wall side opposite to the side on which the hinge is provided, it becomes easy to perform the attaching / detaching operation of the insertion tube of the upper lid to the extraction tube. An increase in the height from the top wall top surface to the bottom surface of the flange piece can be achieved without difficulty, and the dripping prevention function can be sufficiently enhanced in a state where a favorable opening / closing rotation operation of the upper lid is stably maintained.
