Abstract: A sealed liquid container with a bottle, base, piercer, and cap. The bottle is a blow-fill-seal container with a body, dispensing head connected to the body by a neck, and a fluid chamber. The base has a socket that accepts the dispensing head and permanently attaches to the bottle by one or more fingers extending radially into the socket and under the shoulder of the dispensing head. A keying mechanism prevents the base from rotating on the bottle. The piercer has an axially-extending, sharpened, hollow tube. In shipping mode, the piercer is turned onto the base until the tube tip is touching the dispensing head. To use, the piercer is turned until the tube tip penetrates the dispensing head into the fluid chamber, and the piercer locking mechanism is engaged to prevent removal of the piercer. A cap turns onto the piercer.

Abstract: A dosing system for analgesic liquid suspensions including unit dose containers made using blow-fill-seal (BFS) technology. The containers come in various sizes and hold appropriate doses for specific weight ranges. Each container has body with a compartment for holding the liquid, finger rests for squeezing the container to expel the liquid, a tab at one end for labeling, and a twist-off closure at the other end. In the larger containers, the opening end has a lip rest, which is a flattened section that includes opposed, curved depressions. In the smallest container, the opening end has a long tapered neck. The suspension has a relatively low viscosity to ensure more complete dose evacuation from the container. The containers will be sold in assemblages of various combinations of sizes.
