Benefits of technology

"The present invention is a manufacturing process for paintballs that uses Blow-Fill-Seal technology. This technology has been used for many years in the medical industry and is now uniquely adapted to make paintballs. Traditional gelatin paintballs have many drawbacks, but paintballs made using Blow-Fill-Seal technology have several benefits. The material used to make the paintball shell is biodegradable, meaning it is not affected by temperature and humidity changes, which allows for longer shelf life and use in extreme conditions without affecting performance. The manufacturing process is simplified and shortened compared to traditional methods. There is no need for dehumidifying rooms after manufacturing. The breakability of the paintball can be controlled by adjusting the amount of resin used to make the outer shell. Overall, this technology produces high-quality paintballs that are more durable and accurate."

Problems solved by technology

None of these drawbacks are found in paintballs formed using Blow-Fill-Seal technology.

Embodiment Construction

[0013] Blow-fill-seal technology, originally developed in Europe in the 1930's and introduced in the United States in the 1960's, has emerged as a preferred method for aseptic packaging of pharmaceutical and healthcare products due to unrivaled flexibility in container design, overall product quality, product output and low operational costs. The multi-step process of blow molding, aseptic filling and hermetic sealing of liquid products may be achieved in one sequential operation on a compact, automated machine frame with fill volumes ranging from 0.1 milliliter (ml) to 1,000 ml.

[0014] A variety of polymers may be used in the process, low and high-density polyethylene and polypropylene being the most popular. The innate ability to form the container / closure during the actual aseptic packaging process allows for custom design of the product to meet the specific needs of the application.

[0015] Recent advancements in machine design allow for insertion of pre-molded, pre-sterilized co...

Abstract

Blow-fill-seal processing is employed to fabricate fully formed and filled paintballs. A blow-fill-seal machine, known in the field of medical container and syringe manufacture, is adapted for making paintballs by employing spherical surface main molds which form blow-molded shells and permit the shells to be filled with suitable paintball dye and then sealing molds are used to seal the filled paintball shell thereby resulting in a fully formed paintball having an accurate spherical surface.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to projectiles which are typically fired from a CO2 or compressed air gas marker. More specifically, the invention relates to a paintball projectile structure formed by an outer blow-molded shell that fractures on impact with a target and leaving a pigmented marking agent contained within. This blow-molded paintball provides benefits not found in traditional gelatin paintballs. The process used to make the paintball is unique to paintball manufacturing and is a basis of this invention. [0003] 2. Background Art [0004] Traditionally the shell of a gelatin paintball is formed with a pair of hemispheres of gelatinous material similar to that used to encase oral medicines such as cold capsules. As is the case with oral medicines, these gelatin shell paint balls are soluble in water. Upon striking the target, a paintball fractures to mark the target with coloring agent contained within the pa...
