20050035475
The present invention relates generally to softgel capsules having decorative and unusual color patterns and to the method and apparatus for manufacturing the same. The instant invention further relates to a paint ball comprising a gelatin capsule defining a closed interior chamber, and a fill material contained within said interior chamber, wherein said fill material incorporates a dye. The invention also relates to gelatin based textured paint balls and to a process and apparatus for the manufacture thereof. This invention further relates to the marbleization of materials, and more particularly, to the marbleization of soft gelatin capsules.
More specifically, the instant invention further provides a method and apparatus for manufacturing paint balls having unusual coloring patterns.
The invention further relates to fragile projectiles and methods for forming the same which are typically fired by compressed gas and which have an outer shell that fractures in a predetermined pattern to disperse paint contained therein.
The invention also provides a gelatin ribbon having special decorative colored effects formed according to the present inventive process. Alternatively, the instant invention also provides two decorative colored soft gelatin ribbons to form a completely patterned soft gelatin capsule, the patterns on each half either being the same or different. A limitless number of variations in the decorative patterns of soft gelatin capsules may be achieved by the process of the present invention. Furthermore, the method of the instant invention is easy to use, convenient, does not require elaborate apparatus above and beyond that required for the conventional rotary die process. Many new and unique decorative patterns for soft gelatin capsules can be made by the process of the present invention.
Additionally, this invention relates to processes for making novel target shooting capsules having special decorative effects and having a relatively small diameter, and made from nontoxic, soft elastic gelatin capsule.
The use of soft gelatin capsules for marking trees with a marking fluid has been disclosed in U.S. Pat. No. 3,861,943. According to the '943 patent, the gelatin capsule has a wall thickness from 0.02 inches to 0.03 inches and a diameter of about 0.25 inches to 0.75 inches. The capsule contains from 0.25 cc to 1.25 cc of marking fluid, generally a pigmented liquid such as paint, lacquer or the like, and is useful for marking trees. However, the marking capsule of the '943 patent has deficiencies in other applications such as target shooting. In particular, the amount and type of fluid in the capsule create difficulties for use in target shooting. A key problem is caused by the fact that the shape of the capsule is based on the amount of fluid contained therein. As a result, the capsule is not suitable for target shooting as it is not spherically shaped. Furthermore, the amount and type of marking fluid creates a very large splatter mark, around two inches in diameter which is suitable for trees but useless for competitive target shooting. Another problem is that due to the make up of these capsules conventional air guns must be modified to fire the same.
U.S. Pat. Nos. 5,672,300 and 6,022,499 teach an apparatus for forming patterned soft gelatin capsules including a first spreader box and a second spreader box disposed therein, with the first box holding a first dispensable flowable gelatin mass and the second spreader box holding a second dispensable flowable gelatin mass with the second gelatin mass being of a type that is visually distinct from the first gelatin mass. The first gelatin mass is dispensed through an opening formed between an outer surface of the second spreader box and an inner surface of the first spreader box to form a ribbon whereat the second gelatin mass is dispensed from an opening in the second box to flow onto the ribbon to form the patterned gelatin ribbon. Thereafter the capsules are formed by introducing a fill between a pair of patterned ribbons being conveyed on a pair of rollers.
U.S. Pat. No. 5,246,635 describes a process for the manufacture of textured softgel capsules, by controllably directing a flowable gelatin mass onto the outer surface of a drum, to form a ribbon of substantially uniform thickness thereon and thereafter passing the ribbon between a roller of reduced diameter with a textured surface and the drum surface while applying sufficient pressure to the roller to cause the textured surface to impart a matching texture on the surface of the ribbon, providing a second gelatin ribbon, forming a plurality of filled capsules from the gelatin ribbons with the matching texture defining the outer surface of at least a portion of each of the capsules.
It is also well known to use paint balls in the sport called “War Games” wherein two or more opposing teams are equipped with gas powered guns shooting paint balls at each other. When the paint ball strikes an opponent, the paint ball shatters and releases the fill material or “paint” onto the player. In doing so, the player who has been struck by the paint ball is marked and eliminated from the game. The game terminates when only one or more members of the same team have not been marked.
Currently, paint balls in the market place are of a single color. Thereby leaving a market for paint balls with a more striking decorative appearance. Accordingly, the present invention provides a method and apparatus for making gelatin based paint balls and capsules having unusual coloring which will be eye catching thereby increasing interest and sales.
The prior art is replete with methods to produce color and patterns in cast materials to simulate the natural look of marble like products. However, in most instances there is little or no control over the pattern or its reproducibility. Furthermore, few, if any, of the prior art methods are readily adaptable to automation for consistent production of matching articles.
The line marking in the gelatin ribbon of the present invention, is achieved by modifying the gelatin spreader boxes. With the help of specially designed pipelines, a different color gelatin is charged into a spreader box through a series of conduits, thus creating an interlinear design in the newly formed gelatin ribbon when the same is dispensed thereon. When a pair of ribbons are filled with paint, dye or the like, the color lines grow wider creating a degradation thereof resulting in an attractive appearance.

With reference to
As seen tanks 16, 17, usually made of stainless steel, are filled with different types of gelatin and are connected to temperature module 15 via lines 50, 51 for controlling the temperature. The gelatin is caused to flow through pipelines 16, 17, generally made of plastic, having a diameter of one or two inches, by pumps 9 and 11, respectively. The pumps have heating elements and temperature sensors, 12, 12 to keep the pumps at a constant and sufficient temperature to maintain the gelatin in its fluid state. The sensor and the heaters 12, 12 are electrically connected to a module 15 by lines 52, 53.
The pumps 9 and 11 are motor driven and each have a flow-regulating valve and vent (not shown in the drawings) to extract the air trapped inside the pipeline when the machine is started up.
The two different gelatins pass out of the pump 9,11, respectively, into stainless steel pipelines 7, 7 having a diameter of one or two inches. The pipelines 7, 7 are covered with a heating element 25 of ferrous tin coated with a fiber-glass shield and are connected to module 15 by lines 14,14. The entire pipeline is lined (not shown) with a thermo-shrinkable material. The pipelines 7, 7 include unions in their make up and have connectors 8, 8 to connect one heater to the other. These resistance heaters 25, 25 are successively connected to the modules by means of cables and connectors 14, 14. Each pipeline 7, 7 bifurcates in a tee 4, 4, respectively, thereby introducing their gelatin into each of the spreader boxes 3, 3 causing each to be filled with two different types of gelatin. The spreader boxes 3, 3 are also equipped with electrical resistance heating elements, and a temperature sensor, not shown in the drawings.
These pipelines 18, 18 are wrapped with the same type of heating element as described for the above mentioned pipelines and includes a dimmer 22 to regulate the current supplied to the resistance heating element in order to avoid overheating that may cause damage to the plastic pipelines, or otherwise harden the gelatin, thus obstructing, or clogging the system. This system takes the electrical energy from the already described gelatin pipeline itself, through connectors and cables 20 and 21.
The spreader box 34 can be mounted on box 29 by any suitable means and includes an adjustable plate 40 associated therewith for regulating the flow of gelatin through the openings 37, 37 by adjusting the size thereof. The plate 40 is constrained in flanges 41, 41 for up and downward movement, the movement of which is regulated by knobs 31,31.
Orifices 37 can have any of the symmetrical or asymmetrical geometrical shapes as shown in
The gelatin is introduced into the main conduit 36 at any point alongside the exterior face of the box 3, and if desired it can have one or more introduction points.
During the development of this invention, a great variety of colorful effects have been achieved on the gelatin ribbon when changing the position, the geometry, the shape, the amount of orifices, and the inclination angles of the orifices 37 as well as the injected gelatin flow.
