Description

SANITIZING APPARATUS AND METHODS OF USING THE SAME

Cross-Reference to Related Applications

[0001] The present patent application claims the benefits of priority of U.S. Provisional Patent Application No. 62/942,797 entitled “SANITIZING APPARATUS AND METHODS OF USING THE SAME”, and filed at the United States Patent and Trademark Office on December 3, 2019, the content of which is incorporated herein by reference..

Field of the Invention

[0002] The present invention generally relates to apparatus and methods for sanitizing industrial equipment and/or tools, in particular, but not limited to, equipment and tools used in the manufacturing of cosmetic products.

Background of the Invention

[0003] Making cosmetics can be very similar to cooking, however making cosmetics requires extra care to avoid contamination as unlike many foods needing to last up to 24 hours only, a cream may need to last as long as 24 months. For instance, the U.S. Federal Food, Drug and Cosmetic Act prohibits the introduction or delivery for introduction into interstate commerce of cosmetics that are adulterated or misbranded (Sec. 301). A cosmetic may be deemed adulterated (Sec. 601) for essentially four reasons, namely:

1. It may be injurious to users under conditions of customary use because it contains, or its container is composed of, a potentially harmful substance.

2. It contains filth.

3. It contains a non-permitted, or in some instances non-certified, color additive.

4. It is manufactured or held under insanitary conditions whereby it may have become injurious to users or contaminated with filth.

[0004] A cosmetic product that is manufactured or held under insanitary conditions may have become injurious to users or contaminated with filth. Utensils, pumps, transfer piping, containers and cosmetic contact surfaces of equipment must be well-maintained and clean and must be sanitized at appropriate intervals. Rigorous adherence to good manufacturing practice minimizes the risk of adulteration or misbranding of cosmetics.

[0005] Equipment, tools and utensils used in processing, holding, transferring and filling cosmetics are of appropriate design, material and workmanship to prevent corrosion, buildup of material, or adulteration with lubricants, dirt or sanitizing agent. Sanitizing by washing and drying containers (e.g. barrels, jars), pumps (e.g. “Lutz” type pump) and pipes (e.g. flexible hose washer) may be particularly difficult due to their specific designs with the presence of numerous portions of the equipment that are not easily accessible, such as grooves, internal portions of pipes, etc. Furthermore, cosmetic products are typically made from oily, viscous and thick ingredients (e.g. balms, ointment, creams, etc.) which requires vigorous washing with specific washing solutions or detergents in order to be properly washed and sanitized.

[0006] There is thus a need for novel apparatus and related methods for sanitizing by washing and drying industrial equipment, such as for instance those used for the making of cosmetic products.

[00172] The hose washer (500) further comprises a plurality of nozzles, such as ball- head nozzles (540), extending inwardly from the tubular wall (514) to spray hot water, steam or washing/rinsing solutions towards the outer surface of the hose placed on the rack (530).

[00173] As illustrated on Figures 31 and 34, the front door (512) comprises an outlet (550) extending inwardly from the door inside the enclosure (511) and operatively connected to an inlet (560) extending outwardly from the door (512).

[00174] During the cleaning phase, a flexible hose is slid into the "Hose washer", then it is connected in the outlet (550) of the inner part of the door using a fastening system (570) for securely fixing the hose to the outlet during the sanitization thereof. For instance, a Tri-clamp connection can be used. The operator closes the door and then connects to the inlet (560) outside of the door to the piping provided for this purpose. The inlet/outlet of the door act as a hermetic connection to send water at a high rate into the flexible hose. Thus, the outer surface of the hose is cleaned by the ball-head nozzles (540) and the inner surface of the hose is cleaned by injecting water via the inlet/outlet of the door once the door is hermetically closed. During the sterilization phase, the "Hose washer" acts as an autoclave by spraying the hose with steam. As shown on Figure 32, the enclosure (510) can be inclined in order to allow the water to flow towards the back wall (513) and then to a recirculation basin (550) to prevent stagnation of water.
