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, by pulling the lid that is integrally connected via a hinge, the two weakening lines are broken to cap the cap. The whole is removed from the casing mouthpiece and separated.
[0004]
[Problems to be solved by the invention]
However, in the above-described prior art, when removing the cap, the casing is first pulled outward to break the entire longitudinal weakening line and the circumferential weakening line connected to the same at the same time. Therefore, a large operating force is required for the first weakening line breaking operation, and there is a problem that the sorting operation cannot be performed quickly and smoothly.
[0005]
Therefore, the present invention was devised to solve the problems in the prior art described above, and makes it possible to easily perform the breakage of the weakening line at the time of sorting and discarding, particularly the first breaking operation with a small operating force. Therefore, it is an object of the present invention to achieve easy, quick and smooth separation and removal of the hinge cap.
[0006]
[Means for Solving the Problems]
Of the present invention for solving the above technical problems, the first invention is:
It is a hinge cap made of synthetic resin with a lid at the rear end of the cap body,
The cap body includes an assembled cylinder that is assembled to the outer periphery of the housing mouthpiece, and a connecting plate that is located at the top of the assembled cylinder.
The connecting plate is connected to the assembled cylinder in a non-breakable manner via a connecting portion provided at one end of the left and right ends along the circumferential direction of the assembled cylinder, and the connecting portion is connected to the other end at the other end. Connected to the assembled cylinder in a breakable manner,
Further, at the base end portion of the connecting portion, it is connected to the thin rear weakening line extending from the upper end to the lower end of the assembled cylinder through the connecting portion side and the upper end of the rear weakening line, and the upper surface of the assembled cylinder is surrounded by A thin upper weakening line extending in the direction is provided on each assembled cylinder,
The connecting plate and the lid are connected via a hinge;
It is in.
[0007]
When separating and discarding, when the lid is opened and pulled outward, the connecting portion is first broken through the hinge and the connecting plate, and then the rear weakening line and the upper weakening line of the assembled cylinder of the cap body are broken. Therefore, if the lid is pulled up as it is, the cap main body can be easily detached from the casing mouthpiece.
[0008]
In that case, the first breaking operation can be easily achieved with a small operating force because it is only necessary to break the connecting portion that connects the part of the connecting plate and the assembled cylinder so as to be broken. Further, the subsequent breakage of the assembled cylinder of the cap body can be easily achieved by the repulsive force of the initial operating force.
[0009]
2nd invention adds the structure which connected the connection part to the cylinder with an assembly | attachment of the cap main body by the thin connection piece to the structure of 1st invention to the connection part.
[0010]
In the invention according to claim 2, since the connecting portion constituted by the connecting piece can be broken by the lever action with the one side end portion of the connecting plate as a fulcrum, the breaking of the connecting portion can be performed with a small force. The hinge cap can be removed from the housing simply by continuing the operation mode in which the connecting portion is broken as it is.
[0011]
3rd invention adds the thing which connected and comprised the connection part to the cylinder with an assembly with the thin connection piece to the structure of 1st invention at the upper end part of a connection board.
[0012]
In the third aspect of the invention, similarly to the second aspect of the invention, the connecting portion formed of the connecting piece can be broken by the lever action with the one end of the connecting plate as a fulcrum. Can be easily achieved with a small force, and the hinge cap can be removed from the housing simply by continuing the operation mode in which the connecting portion is broken.
[0013]
4th invention adds the thing which connected and comprised the connection part to the assembly | attachment cylinder through the thinning weakening line to the structure of 1st invention.
[0014]
In the fourth aspect of the invention, the connecting portion can be broken by the lever action with the one side end portion of the connecting plate as a fulcrum, so that the breaking of the connecting portion can be achieved with a relatively small force. Since the breaking operation of the part becomes the breaking operation of the weakening line as it is, the operation of removing the hinge cap from the housing becomes simple.
[0015]
5th invention adds the structure which extended the front-end | tip part of the connection board and provided the handle part to the structure of 1st invention.
[0016]
According to the fifth aspect of the invention, since the connection portion breaking force can be directly applied to the connecting plate by having the handle portion, a reliable and stable connection portion breaking operation can be obtained.
[0017]
