Abstract
Abstract The needle pack includes a base member, provided with a needle holder portion and a flexible cover member. The base member has one end edge attached to an end edge of the cover member and an engaging lug is formed at the other end of the cover member for engagement with a hole formed in the base member. The cover member is formed with a convex portion near the edge attached to the base member and a concave portion formed in contact with the base member adjacent to the convex portion whereby when the convex portion is pushed down, the cover member springs up due to the fulcrum action of the concave portion and the engaging lug is disengaged from the hole of the base member to open the cover member.
