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.

Abstract: A foldable needle pack comprises a base member, which is created or scored so as to present a fold line comprising a first base portion and a second base portion bordered by the fold line, a needle holder portion mounted near the fold line on the second base portion, and two closely aligned rigid transparent cover members, each formed as a hollow shell wherein the first cover member is at the end edge thereof opposite its open side attached to the first base portion while the second cover member is at the peripheral edge attached on the second base portion whereby when the first base portion is bent back along the fold line relative to the second base portion, the top of each of needles slides on the inner surface of the first cover member and then a free end edge of the first cover member comes into friction contact with the side of the needles to hold the needle pack V-shaped.
