Filling systems for bone delivery devices

A kit facilitating the placement of at least one substance within a covering, the kit comprising:

• a funnel shaped container having a scoop portion connected to a barrel and a plunger, the barrel having a proximal opening configured to receive a portion of the plunger and a distal opening to dispense the at least one substance into the covering, the scoop portion comprising a central flat base, the plunger adapted to slide through the barrel of the funnel shaped container for pushing the at least one substance out of the distal opening and into the covering, the plunger comprising a smooth elongated portion extending within the hollow barrel, a projection and a flared solid handle at one end of the plunger, the projection and the solid flared handle being wider than an inner diameter of the hollow barrel so that the projection and the solid flared handle prevent the one end of the plunger from entering into the hollow barrel;
• an inner tray with recesses configured to receive the funnel shaped container and the plunger;
• a retainer positioned on top of the inner tray, the retainer for holding the funnel shaped container and plunger in place;
• an inner lid and an outer lid for sealing the funnel shaped container and the plunger from the environment.

A method of filling a covering with at least one substance which comprises:

• providing a covering having at least one flared opening;
• providing a funnel shaped container having a scoop portion connected to a hollow barrel, the hollow barrel having a proximal opening configured to receive a portion of a plunger and a distal opening configured to dispense at least one substance into the covering, the scoop portion comprising a central flat base, the barrel configured for insertion into the flared opening of the cover;
• providing the at least one substance into the funnel shaped container;
• providing the plunger comprising a smooth elongated portion extending within the hollow barrel, a projection and a flared solid handle at one end of the plunger, the projection and the solid flared handle being wider than an inner diameter of the hollow barrel, and pushing the at least one substance with the plunger through the barrel out of the distal opening and into the covering.
