該部分を指先で把持するようにしていた。 Conventionally, in order to save material for the pusher, a pusher has been used that includes an insertion rod with four ribs and a cross-sectional shape. In order to facilitate operations such as pulling out the pusher inserted into the syringe barrel, a flange is integrally provided at the rear end of the insertion rod, and the insertion rod is designed such that the rear end of the insertion rod adjacent to the flange has a small diameter. form a narrow part towards the axis of the
This part was to be grasped with the fingertips.
しかしながら、該部分は断面形状が十字形状で
あるため指先で把持するのが容易ではなく、また
小径とするために小幅としたので該部分で折れる
場合があつた。 However, since the cross-sectional shape of this part is cross-shaped, it is not easy to grasp it with fingertips, and since the width is made small to make the diameter small, there are cases where the part breaks at this part.
本考案はかかる従来の不都合を解消するために

を一体に設けたことを特徴とする。 In order to eliminate such conventional inconveniences, the present invention improves the structure of the rear end of the insertion rod to provide a strong pusher that is easy to grip with fingertips and is free from breakage. 3, 4, and 5, an insertion rod 1 having a cross-shaped cross section, a gasket 6 provided at the tip of the insertion rod 1, and a gasket 6 provided at the rear end of the insertion rod 1 so as to be perpendicular to the axis of the insertion rod 1. A small edge portion 8 in which each of the outer edges of the ribs 2 and 4 that are vertically connected at the rear end of the insertion rod 1 has a narrow width toward the axis of the insertion rod 1; gripping plates 10 and 11 forming a flange 9 and mounted on both small edges 8 and 9, respectively, and connected to the flange 7;
It is characterized by being integrated.
本考案の実施の一例を示す第１図乃至第３図に
従つて更に詳説すれば次の通りである。 A more detailed explanation will be given below with reference to FIGS. 1 to 3 showing an example of the implementation of the present invention.
図示のものは注射筒Ａに用いる押子Ｂであつて
硬質合成樹脂により４枚のリブ２，３，４，５で
断面形状を十字形状に形成した挿入杆１の先端部
にガスケツト６を設け、後端に一体に平板状のフ
ランジ７を形成した点では従来のものと異ならな
い。 The one shown is a pusher B used for a syringe barrel A, and is made of hard synthetic resin and has a cross-sectional cross-sectional shape with four ribs 2, 3, 4, 5, and a gasket 6 is provided at the tip of the insertion rod 1. , is similar to the conventional one in that a flat plate-like flange 7 is integrally formed at the rear end.
本考案のものにあつては挿入杆１のフランジ７
と接続する後端において、第２図示のように垂直
に連設する一対のリブ２，４の夫々の外縁を挿入
杆１の軸線に向つて小幅として軸線に沿つてフラ
ンジ７の内面に至る小縁部８，９とし全体として
小径部に形成した。そして該小縁部８，９に対し
て垂直に接続して載架されると共に前端をリブ
２，４に接続した後端をフランジ７の内面に接続
する互に平行な把持板１０，１１を設けた。 In the case of the present invention, the flange 7 of the insertion rod 1
At the rear end connected to the insertion rod 1, the outer edges of each of the pair of vertically connected ribs 2 and 4 are narrowed toward the axis of the insertion rod 1, as shown in the second figure, to extend along the axis to the inner surface of the flange 7. The edges 8 and 9 were formed as a small diameter portion as a whole. Grip plates 10 and 11 are parallel to each other and are mounted perpendicularly to the small edges 8 and 9, and have their front ends connected to the ribs 2 and 4 and their rear ends connected to the inner surface of the flange 7. Established.
そのため第３図示のように把持板１０，１１と
リブ２，４とは断面形状がＨ字形状となる。 Therefore, as shown in the third figure, the gripping plates 10, 11 and the ribs 2, 4 have an H-shaped cross section.
図示する実施例では把持板１０，１１を互に平
行するように設けたがフランジ７に向つて上方へ
傾斜するように設けてもよい。また、把持板１
０，１１によつて断面形状がＨ字形状となつて補
強されるので、この部分における他のリブ１，３
は必要に応じて省略してもよい。 In the illustrated embodiment, the gripping plates 10 and 11 are provided parallel to each other, but they may be provided so as to be inclined upwardly toward the flange 7. In addition, grip plate 1
Since the cross-sectional shape becomes H-shaped and is reinforced by ribs 0 and 11, the other ribs 1 and 3 in this part
may be omitted if necessary.
本考案によるときは、押子の後端部に形成した
小径部に一対の把持板１０，１１を設けたのでこ
