Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hinge cap constructed by assembling a lid body to a cap main body that is assembled to a mouthpiece of a casing and has a pouring outlet for contents liquid.
[0002]
[Prior art]
For example, this type of hinge cap, which is tightly assembled to the casing tube that contains the content liquid such as dressing and noodle soup, usually has a pouring cylinder that forms the pouring port for the content liquid standing on the cap body. In addition, a plug cylinder piece that fits and removes from the extraction cylinder of the cap body and opens and closes the outlet is formed on the inner surface of the top wall of the lid body hinged to the cap body.
[0003]
[Problems to be solved by the invention]
By the way, in this kind of hinge cap, depending on the type of the content liquid, when the content liquid is poured out, it is necessary to shake out the content liquid with the lid closed, and then pour out the content liquid. However, since the content liquid adheres to the inner surface of the top wall of the lid by this stirring operation, when the casing is tilted during pouring, the content liquid adhering to the lid drops, and the outer surface of the casing There was a problem that the surroundings could be soiled.
[0004]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and a technique for recovering the content liquid adhering to the inner surface of the lid of the hinge cap by stirring the casing or the like into the casing. An object of the present invention is to provide a hinge cap that prevents liquid dripping at the time of pouring and that can be smoothly and smoothly poured without contaminating the outer surface and the periphery of the housing.
[0005]
[Means for Solving the Problems]
Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is:
A pouring tube that is tightly assembled to the housing mouth tube and forms a pouring outlet for the content liquid is erected in a form in which the rear end portion is notched, and a seal tube piece is erected outside the pouring tube. Having a cap body,
The lid body is connected to the rear end of the cap body via a hinge, and has a lid body on the inner surface of the top wall that hangs down a sealing cylinder that is in close contact with the upper end surface of the sealing cylinder piece of the cap body when closed.
Extending the inner surface side portion of the rear end of the sealing cylinder of the lid downward to form a flange piece;
A locking portion is provided on the rear surface of the lower end portion of the flange piece to lock the upper end of the seal cylinder piece of the cap body when the lid is opened, and to hold the lid body in a predetermined forward tilting posture. Sometimes it was configured with a locking projection (19) that abuts and locks on the inside of the upper end of the seal tube piece ,
It is in.
[0006]
When the casing is poured out, the contents liquid may adhere to the inner surface of the top wall of the lid of the hinge cap due to stirring of the contents liquid by shaking the casing or carrying the casing.
[0007]
In such a case, when the lid of the hinge cap is opened for pouring out the internal solution, the locking portion provided on the rear surface of the collar piece is locked to the upper end of the seal cylinder piece, so the lid body is in front of the upright position. It stops at a predetermined tilted position, and this posture is maintained.
[0008]
Therefore, the content liquid adhering to the inner surface of the top wall of the lid body flows down, is guided by the inner surface of the sealing cylinder and the flange piece, drops from the tip of the flange piece to the notch portion at the rear end of the dispensing cylinder, and It is quickly recovered in the body.
[0010]
Furthermore , since the hook locking portion is constituted by a locking protrusion having a simple protruding piece structure, the structure of the locking portion is very simple.
[0011]
The invention according to claim 2 is a pair of locking projections formed in the invention according to claim 1, in which a groove for locking the locking portion of the collar piece to the upper end of the seal cylinder piece is formed when the lid is opened. Consists of the above.
[0012]
In the invention according to the second aspect , the predetermined forward tilting posture of the lid body is stably maintained without being changed into a paranoid in both opening and closing directions.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 and 2 show a first embodiment of the present invention. A hinge cap is assembled to a cap body 1 assembled to a casing mouth tube 21, and a hinge 20 is provided at the rear end of the cap body 1. It is comprised from the lid | cover body 13 connected.
[0014]
The cap main body 1 is a fitting cylinder in which the peripheral wall 15 of the lid 13 is externally detachably fitted to the inner side of the upper end of the assembled cylinder 2 fitted to the outer periphery of the casing mouth cylinder 21 via the top wall 3. 4, and a thin seal cylinder piece 5 formed in an upward inward gradient is connected to the inner edge of the upper end of the fitting cylinder 4.
[0015]
In addition, an insertion tube 6 that is fitted into the housing mouth tube 21 is suspended from the inner end of the top wall 3, and a tapered wall 7 that is formed in a downwardly descending direction inside the insertion tube 6. Further, a pouring cylinder 8 forming a spout is continuously provided at the inner end of the tapered wall 7 in a form in which the rear end portion is notched.
[0016]
The bottom surface of the spout of the cap body 1 is closed by a mouth wall 9 having an inner portion of the breaking groove 10 as a removal wall portion 11, and this removal wall portion 11 uses a pull ring 12 integrally provided on the upper surface. By pulling up occasionally, it is broken and removed at the breaking groove 10 (see FIG. 2).
[0017]
A sealing cylinder 16 is provided on the inner surface of the top wall 14 of the lid 13 so as to be in close contact with the upper end surface of the sealing cylinder piece 5 when the lid is closed. An arc-shaped groove-shaped flange piece 17 is continuously provided at the rear end portion in such a form that its inner surface side portion extends downward.
[0018]
As shown in FIG. 2, the rear surface of the lower end portion of the flange piece 17 is in contact with and locked to the inner side of the upper end of the seal tube piece 5 so that the lid body 13 is inclined slightly forward rather than upright. In order to hold it, a locking projection 19 constituting the locking portion 18 is provided.
[0019]
FIG. 3 shows a second embodiment of the present invention, in which a pair of locking projections formed with a groove for locking the locking portion 18 of the collar piece 17 to the upper end of the seal cylinder piece 5 are shown. 19, and the predetermined forward tilting posture holding of the lid body 13 by this locking is achieved so as not to be displaced in both the opening and closing directions.
[0020]
【Effect of the invention】
Since the present invention has the above-described configuration, the following effects can be obtained.
In the first aspect of the invention, when the lid is opened during use, the lid stops at a predetermined forward tilt position, and its posture is maintained, so that it adheres to the inner surface of the top wall of the lid. The liquid content flows down, is guided to the inner surface of the sealing cylinder and the flange piece, falls from the tip of the flange piece to the notch portion at the rear end of the extraction cylinder, and is quickly collected in the casing.
[0021]
Therefore, when the content liquid is poured out with the casing tilted forward, the content liquid adhering to the inner surface of the lid is dripped well and smoothly without contaminating the outer surface and the periphery of the casing. be able to.
[0022]
In the second aspect of the invention, the hook locking portion can be configured with a very simple structure.
[0023]
In the invention according to claim 3, the locking portion of the collar piece can be configured with a simple structure, and the predetermined forward tilting posture of the lid body is stable so as not to be distracted in both opening and closing directions. Therefore, a good use state can be obtained.
