DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pierced earlobe piercer set and a fastener mounting device for the pierced earlobe piercer.

[0002]

2. Description of the Related Art A pierced earlobe piercer has an elastic U-shaped main body in which a first arm and a second arm are connected to each other at a base end thereof, and a pierce needle cartridge is provided at a distal end of the first arm. And a cylinder-shaped piercing needle support for inserting a piercing needle and a plunger, and a stopper supporting portion for supporting one stopper to which the piercing needle is coupled at the tip of the second arm. See JP-A-4-89014). The cartridge is of a split type for accommodating a piercing needle head, and the tip of the piercing needle projects forward from the cylinder. The plunger has a rear end protruding rearward from the cylinder. The plunger is provided with a tongue piece that contacts the rear end of the cylinder.

[0003] The method of using the earlobe perforator is to hold the U-shaped body with one hand, insert an earlobe between the piercing needle and the stopper, and narrow the spread of the U-shaped body to stop the piercing needle. Piercing the ear lobe with the cartridge by pushing the plunger with a finger, piercing the ear lobe and connecting it to the stopper at the back thereof,
That is. Since the tongue piece of the plunger is broken when a force exceeding a predetermined value is applied, the tongue piece acts to accelerate the forward movement of the plunger. When the gripping force of the U-shaped main body is weakened, the spread increases, the piercing needle comes off the cylindrical portion together with the cartridge, and the cartridge can be removed from the piercing needle.

[0004]

The earlobe pierced by the piercing needle is initially in a so-called damaged state, so that the piercing needle and the stopper are used to prevent bacteria from entering the earlobe. Must be provided to users in a sterile condition. In this regard, in the ear lobe punch for piercing,
Clean piercing needles and fasteners can be provided to the user in a state of being mounted on their supports and aseptically packaged.

[0005] However, when piercing holes are made in the left and right earlobes, after using the above-mentioned clean piercing needle and fastener in one earlobe, the piercing needle and fastener for the other earlobe are connected to those earlobes. The user needs to wear it on the support. At this time, even if the piercing needle and the stopper itself are sterilized in advance, the piercing needle and the stopper may be attached to the piercing needle and the stopper because they are handled by hand for mounting.

The piercing needle supporting portion, which has an elastic engaging portion and supports the piercing needle, is opposed to the stopper supporting portion which supports the stopper with an earlobe. The needle is elastically deformed and connected to the stopper so that the elastic engagement portion of the stopper is disengaged from the stopper support.

[0013] The fastener mounting device of such a piercing earlobe punch includes a handle, and the elastic engaging portion of the fastener is engaged with the projection of the fastener supporting portion. And a stopper holding portion for holding the elastic engaging portion in an exposed state so that the elastic engaging portion is exposed.

Therefore, as in the case of the pierced earlobe piercer set, the pierced earlobe piercer can be mounted on the pierced earlobe perforator without directly touching the stopper.

[0015] In the fastener mounting device for the ear piercing device for pierced ears, the stopper is formed from a body having a penetrating portion through which the needle portion of the piercing needle penetrates, and a portion on both sides of the penetrating portion of the main body. A pair of projecting portions projecting rearward, between the two projecting portions is formed an engaging portion that elastically engages with the stopper supporting portion, and the needle portion of the piercing needle is coupled to the engaging portion. The stopper support is formed at a coupling portion, and the stopper support has a receiving surface on the front surface with which the rear surface of the stopper body abuts, and an insertion portion into which both protrusions of the stopper are inserted on the receiving surface Are opened, and the insertion portion is opened in one side of the direction in which the two protrusions are arranged, and furthermore, when the two protrusions are inserted from the front surface into the opposing inner surfaces with the insertion portion. A long projection in the front-rear direction that fits between the two projections is formed, and The part is formed by legs that are opposed to each other before and after the handle, and the stoppers are arranged and sandwiched so that both protrusions of the stopper are arranged in the direction in which the legs extend. The rear leg of the part is inserted into the insertion part of the fastener support part together with the two projections of the fastener so that both projections of the fastener support part fit between the two projections. Moreover, it is preferable that the stopper is formed to be narrower than both the projecting portions of the stopper so that the stopper can be pulled out from the one opening.

That is, if aseptic packaging is performed with the fastener being sandwiched between the front and rear legs of the fastener mounting device, the user removes the package, holds the handle, and then attaches the leg to the fastener. By inserting the rear leg portion from the opening of the stopper support portion, the stopper is inserted without touching the stopper at all. It can be supported by a support. In this case, when the rear leg is fitted into the insertion portion of the stopper supporting portion together with the both projecting portions of the stopper from the front surface, the elastic engagement portion between the two projecting portions is formed on both inner side surfaces of the stopper supporting portion. The stopper is engaged with and supported by the stopper supporting portion by fitting into the projection. And because there is this engagement,
When the fastener mounting device is pulled out from the opening of the fastener support portion, the fastener remains in a state supported by the fastener support portion.

[0017]

Therefore, according to the present invention, since the fastener mounting device has the handle and the fastener holding portion, it is possible to use the earlobe for piercing without directly touching the fastener with the hand. It can be attached to the stopper support portion of the perforator, which is advantageous in preventing the invasion of germs from the piercing hole of the earlobe, and since the stopper attaching device has a simple structure, its production is simple. It is easy and easy to handle.
