Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin hinge cap which is assembled to a casing and can be easily separated from the casing at the time of disposal.
[0002]
[Prior art]
As a conventional example of this type of hinge cap, one described in Utility Model Registration No. 2596699 is known.
[0003]
The hinge cap described in this publication is provided with a longitudinal weakening line extending from the upper end to the lower end in the vicinity of one end of the hinge on a cylinder with a cap body fitted to the outer periphery of the casing mouth tube. In the top plate, a continuous weakening line is provided at the top of the weakening line, and at the time of disposal, the weakening line and the weakening line are broken by pulling a lid connected via a hinge. The entire cap is removed from the housing mouthpiece and separated.
[0004]
[Problems to be solved by the invention]
However, in the above-described prior art, when removing the cap, the lid is first pulled sideways to break the weakening line and the weakening line, and then the weakening line breaks in the middle of the circumferential direction. By the way, since the cap body has to be detached from the casing mouth tube by pulling the lid upward, there is a problem that the operation of removing the cap is troublesome and troublesome.
[0005]
In addition, the shock when pulling the lid upward to release the cap body may cause the content liquid adhering to the inner surface of the cap body, particularly the inner cylinder (seal cylinder), to scatter and stain the surroundings. There was a problem.
[0006]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and facilitates the operation of removing the hinge cap from the housing mouthpiece at the time of separation and disposal, and the contents at the time of removal. It is an object of the present invention to prevent the splashing of the liquid, and to achieve the hinge cap separation easily, quickly and smoothly.
[0007]
[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 synthetic resin hinge cap composed of a cap body assembled to the outer periphery of the housing mouth tube by an assembled cylinder, and a lid body connected to the rear end of the cap body by a hinge;
Connecting the front end of the hinge to the rear lower end of the assembled cylinder through a connection plate formed in a substantially L shape ;
A near both sides of the connecting portion, the surface lower end position after the set with tube, to form a notch in which the pair of triangular, a pair of thin over the substantially upper end of the notch in the upper end of the set with barrel Forming the rear weakening line vertically,
Forming a pair of thin upper weakening lines in the circumferential direction on both sides of the rear weakening line on both sides on the peripheral edge of the top of the cap body,
It is in.
[0008]
When separating and discarding, when the lid is opened and pulled upward, the rear end of the assembled cylinder is broken open from the lower end along the rear weakening line via the hinge and connecting plate, and then the top of the cap body is Since the fracture is released along the upper weakening line, the entire cap can be easily removed from the housing mouth tube by pulling up the lid as it is.
[0009]
In that case, the content liquid adhering to the inner surface of the top of the cap body, etc., will fall into the housing with a light shock when the upper weakening line breaks, so the shock at the time of the last cap removal There is no fear of splashing.
[0010]
The invention according to claim 2 is the longitudinal direction of the pair of thin front weakening lines on both sides continuous with the upper weakening lines on both sides from the upper end to the middle of the front end portion of the assembled cylinder. It is a thing which added that.
[0011]
In the invention according to claim 2, since the assembled cylinder is substantially broken at the front and rear ends by the breakage of the front weakening line, the assembled cylinder is assembled to the casing mouth tube. The force is in a very weakened state, so that the removal of the entire cap from the housing barrel can be achieved very easily, quickly and smoothly.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The hinge cap is composed of a cap body 1 assembled to the housing mouthpiece 22 and a lid body 13 connected to the rear end of the cap body 1 via a connecting plate 3 and a hinge 21.
[0013]
The cap main body 1 is provided with a fitting cylinder piece 8 on which an outer peripheral wall 15 of the lid body 13 is detachably fitted on the inner side of the upper end of the assembled cylinder 2 that is fitted to the outer periphery of the casing mouth cylinder. In addition, a sealing cylinder 6 that is in close contact with the inner peripheral surface of the housing mouth cylinder 22 is continuously provided through the top plate 5, and a dispensing cylinder piece 7 that forms a spout on the inner side of the top plate 5. Is erected.
[0014]
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 sometimes, it is broken and removed at the breaking groove 10 portion.
[0015]
On the inner surface of the top wall 14 of the lid body 13, a plug cylinder piece 16 that protrudes in close contact with the inner peripheral surface of the extraction cylinder piece 7 and seals the spout when the lid body 13 is closed is provided.
[0016]
The connecting plate 3 is formed in a substantially L shape, the lower end front surface thereof is connected to the rear lower end of the assembled cylinder 2, and the upper end is connected to the front end portion of the hinge 21. The assembled cylinder 2 is connected at its upper part by a thin connecting piece 4.
[0017]
A pair of triangular incisions 17 are provided in the vicinity of both sides of the connecting portion 3a with the connecting plate 3 at the rear lower end of the assembled cylinder 2, and a pair of triangular incisions 17 are provided. A thin groove-like rear weakening line 18 is formed in the vertical direction from the substantially upper end to the upper end of the assembled cylinder 2.
[0018]
In addition, the peripheral portion of the top portion 1a of the cap body 1, that is, the boundary portion between the fitting tube piece 8 and the assembled tube 2 (see FIG. 4) is a pair of thin walls on both sides continuous with the rear weakening lines 18 on both sides. An upper weakening line 19 is formed in the circumferential direction up to the front end of the cap body 1.
[0019]
The upper weakening line 19 is not limited to the boundary portion between the fitting cylinder piece 8 and the assembled cylinder 2, and for example, the lower end portion of the fitting cylinder piece 8 or the fitting cylinder piece. In order to connect the cylinder 8 with the assembly 8, it may be formed as a flange provided in the shape of an outer casing at the lower end of the fitting cylinder piece 8.
[0020]
The front end of each upper weakening line 19 continues to the upper end of a pair of thin groove-shaped front weakening lines 20 formed in the vertical direction from the upper end of the front end of the assembled cylinder 2 to the middle of the lower part. ing.
[0021]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
According to the first aspect of the present invention, at the time of separation and disposal, the weakening lines at the rear, upper and front portions of the cap body can be reliably broken by only one operation of pulling the lid upward, and the cap Since the whole can be removed from the casing mouthpiece, the separation of the hinge cap can be achieved easily and reliably by a single simple operation.
[0022]
Also, the content liquid adhering to the top inner surface of the cap body falls into the housing with a light shock at the time of breaking the upper weakening line, so it is scattered by the shock at the last cap removal, There is no risk of soiling the surroundings, and separation can be performed smoothly.
[0023]
In the invention according to claim 2, since the assembly force of the assembly cylinder of the cap main body to the housing mouth tube can be sufficiently weakened, the separation operation of the hinge cap can be performed smoothly, quickly and easily. Can be implemented.
