Random direction between maxAngle and minAangle , Quaternion issue....

Hi everybody, Hope someone can help me, i'm stuck with quaternion. So my problem is :

I want to spawn particles around my emitter between two angle

         Quaternion max = Quaternion.Euler(0.0f, 0.0f, _maxAngle);
         Quaternion min = Quaternion.Euler(0.0f, 0.0f, -_maxAngle);

         Vector3 maxVector = max * transform.up;
         Vector3 minVector = min * transform.up;

         Vector3 result = Vector3.Lerp(minVector, maxVector, Random.value);

         float particleSpeed = Random.Range(_particleSpeedMin, _particleSpeedMax);
         Vector3 speed = result * particleSpeed;

So if "_maxAngle" is equal to 30 particles spawn on a cone of 60° (between -30 and 30)

But

My problem is, if "_maxAngle" is equal to 180 so particles spawn in a straight line and not all around my emitter, i noticed that "maxVector" and "minVector" as the same value : (0,-1,0), but i don't know how to manage the problem

Thanks for your attention and hope i can read you soon
