The present invention is directed to a new and useful apparatus for storing and dispensing liquid and solid agents. Specifically, the present invention is directed to an apparatus for storing and dispensing liquids via a multiuse injection system, wherein the container is designed to resist breaking if dropped.
When dosing a large number of animals in a short period of time, for example in a single veterinary visit to a beef feed lot or to a chicken farm, a veterinarian or animal husbandry worker will often use a dosing gun injector. The dosing gun injector allows the user to dose a large number of animals without having to carry a large number of single dose vials. One such one such dosing gun injector is sold by Merial Ltd., the assignee of the instant application, and is shown in
The dosing gun injector has a needle in the cap, which is screwed on to the neck of a large vial of vaccine or other treatment to be injected into the animals. The needle in the cap punctures a seal on the container that prevents contamination of the vaccine. The vial is typically turned upside down in order to prevent any air in the vial or dosing gun from being injected into the animals. The vaccine or other treatment is typically injected by depressing some triggering device. As shown in the example of
Traditionally, vaccines and other treatments are stored in glass vials. As can be readily appreciated, glass, though having the beneficial effect of typically not reacting with the material it contains, is relatively hard and readily breakable. Large vials, of the type commonly used with dosing gun injectors, are approximately the size and shape of the bottles shown in
However, despite its breakability, glass remains one of the most common materials for storage of vaccines and other animal treatments. One benefit of glass is that it is not reactive with most treatments, as some plastics can be. Another reason glass continues to be used are the manufacturing costs involved in switching to other materials. Further, because many vaccines are live cultures, they can only properly be stored in sterile containers. As a result of the heat typically necessary for sterilization, glass remains a common choice for storage of vaccines and other animal treatments.
Due to the breakability of glass, attempts have been made to manufacture a shield or protective cover in which to place a glass bottle and prevent its breakage. One example of such a bottle can be seen in
Accordingly, the present invention is directed to addressing these problems associated with the known prior art containers.

These and other embodiments are disclosed or are obvious from and encompassed by, the following Detailed Description.
The following Detailed Description, given to describe the invention by way of example, but not intended to limit the invention to specific embodiments described, may be understood in conjunction with the accompanying Figures, incorporated herein by reference, in which:
a is a cross-sectional view of a locking mechanism according to one embodiment of the present invention;
In order to develop a container for a glass bottle that prevents breakage and addresses one or more of the objectives described above, tests were undertaken to determine the properties of a glass container in various states and the stresses such a container will withstand without breaking. In a first test, a filled unprotected 250 ml bottle of the type shown in
A second test was conducted to determine whether the use of a simple polypropylene sleeve would provide sufficient protection to prevent breakage of the glass container. A plastic sleeve was place around a 500 ml bottle, having an approximate thickness of between 1/16 and ⅛ of an inch (approximately 0.16-0.32 cm). The sleeve was separated from the bottle by rigid plastic so that the outer diameter of the bottle and sleeve was about 3¼″ (approximately 8.3 cm), and there was about 0.06″ (approximately 0.15 cm) separating the polypropylene sleeve from the glass. The results were that the bottle failed a side impact on a level surface when dropped from about 24-30″ (approximately 60-76 cm), however, a bottle so arranged in a polypropylene sleeve did survive drops of 36″ (about 90 cm) when dropped on either end of the bottle and sleeve arrangement. Again, when dropped onto an edge bearing surface such as angle iron, the bottle suffered failure at heights of only 16-18″ (approximately 40-45 cm).
A third test was undertaken wherein a glass bottle was placed in an extruded PVC sleeve. The sleeve has a thickness of about 0.08″ (about 0.2 cm). The PVC sleeve was fitted with machined polypropylene caps, which prevent the bottle from sliding out of the ends of the sleeve. The caps have a diameter of about 4.2 inches (about 10.7 cm), while the sleeve has a diameter of about 3.9 inches (about 9.9 cm). The bottle, when properly set in the sleeve is isolated from the inner wall of the sleeve by about 0.5″ (about 1.2 cm). The sleeve is actually shorter than the length of the bottle, with the ends of the bottle resting against and being covered by the caps. Tests of this configuration confirmed that on flat surfaces such as concrete the height required for breakage of the bottle was at least 54″ (about 137 cm). Similarly, when dropped onto an edge bearing surface, the breakage height was between 54 and 60″ (about 137-152 cm).

A variety of materials may be used in conjunction with the components of the containers described herein. The materials can be extruded, machined, or worked by a variety of means so as to provided sleeves and caps, which may be attached to one another by a variety of means including adhesives, snaps, hook and loop fastening, threads, and other attachments means known to those of skill in the art. Among the materials useable with the present invention are hard plastics such as acrylic, for the shell or the cylindrical lens other materials could also be used such as polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), ABS plastics, Nylon, polybutylene terephthalate (PBT), polyethylene, such as High Density Polyethylene (HDPE), High Density Polypropylene (HDPP), polycarbonate, polystyrene such as high impact polystyrene (HIP), thermoplastic olefins (TPO's), polyesters, polyurethanes (PU), polyamides, and others. Examples of such additional plastics include those regularly used in the automotive industry for use in the manufacture of plastic parts including bumpers. According to the 2001 Automotive Plastics Report, published by Market Search, Inc., the most commonly used plastics are shown below:

In addition, the plastics used for the sleeve may be made of blends of two or more of the above-identified materials.
Foams for use with the instant invention include polystyrene foam such as Styrofoam, cellular foam such as Poron®, pure gum foam rubber, silicone foam, neoprene foam, polypropylene EPDM foam, polyethylene foam, polyurethane and others. Elsastomeric materials include Santoprene, Silicone, Neoprene, Buna-N and others. One further alternative to foam materials are the use of air, liquid, or gel filled pillows made of for example polyethylene pr polypropylene flexible plastics.
Finally, although in some embodiments it is preferred that the sleeve be substantially clear so that the contents may be examined without opening the sleeve, in others it may be desirable that a tinting if given to the sleeve to prevent the transmission of ultraviolet rays onto the treatment contained within the bottle, the tinting may be of a color to reflect light energy such as white. In addition, it may be desirable that the end caps be made of a color or light orange such as white that reflects light energy so as to prevent the heating of the treatment contained therein.
Having thus described in detail preferred embodiments of the present invention, it is to be understood that the invention defined by the appended claims is not to be limited to particular details set forth in the above description as many apparent variations thereof are possible without departing from the spirit or scope of the present invention.
