Description

  The present invention relates to a magazine loading of a solid product by alternately arranging two different solid products in a product housing of a solid product dispenser, and a method of discharging a magazine loaded solid product. About.

  Extruded clay or ceramic tiles, sometimes called quarry tiles, are relatively inexpensive, durable, and have a relatively low porosity, so they are used for facilities such as restaurants and non-facility Commonly used in kitchens. Cut tiles are formed from natural clay, the composition of which is about 50% hard particles (silicon) and the remaining 50% soft particles (clay component). When a clay tile is baked, a pervious glaze-like coating is formed that encloses pores beneath the surface. Due to the water permeability of this surface, these holes collect and confine various types of dirt that are extremely difficult to clean thoroughly.

  During the cut tile manufacturing process, natural surface irregularities consisting of hard and fine protrusions of silica and inert clay may be generated. The surface texture or unevenness, combined with the surface porosity, provides the optimum coefficient of static friction (static friction) for the tile. Modern cut tiles tend to be slip resistant and some tiles are characterized by anti-slip properties such as the addition of a grit, a coarse grain pattern, or a rougher surface texture. However, anti-slip tiles also wear over time and become dirty, slippery and potentially dangerous. Slicing tiles will soon wear and surface wear due to walking, dirt, and routine surface cleaning. Fine protrusions may be polished and worn away, resulting in a flat surface portion. These worn parts provide a low coefficient of static friction and produce a potentially slippery floor surface. In addition, frying, baking, and frying produces oil that floats in the air, which creates a potentially dangerous film on the tile. Despite routine cleaning, dirt and oil often accumulates over time, and the cut tile floor may become saturated with oil and remain slippery despite routine cleaning.

  Hard surface cleaners useful in both institutional and non-institutional environments can take many forms. One example of such a cleaning agent is an aqueous cleaning agent whose pH can be neutral, acidic, or alkaline when the use solution is produced by dilution. Neutral, acidic, or alkaline aqueous detergents in the use solution are typically formulated with a high percentage of aqueous diluent and a low percentage of detergent. A detergent having a neutral or alkaline pH effectively removes newer oil stains, and a detergent having an acidic pH effectively removes polymerized grease soil. One example of an acidic cleaning formulation useful for cleaning soils containing food residues is disclosed in US Pat. No. 6,432,906, which is hereby incorporated by reference. One example of a basic (alkaline) cleaning formulation useful for cleaning soils containing food residues is described in US Pat. No. 5,474,698, which is incorporated herein by reference. Shall.

  U.S. Pat. No. 5,797,986, incorporated herein by reference, cleans the floor with a first cleaning agent having a pH away from neutrality, followed by a complementary pH. Discloses a method using a second cleaning agent having: In one aspect, the first cleaning agent is an acidic cleaning agent and the second cleaning agent is a basic cleaning agent. In another aspect, the first cleaning agent is a basic cleaning agent and the second cleaning agent is an acidic cleaning agent. This method provides optimal cleaning.

  The cleanliness of hard surfaces such as floors is characterized by a substantially improved coefficient of friction (hereinafter “COF”). A COF greater than about 0.4 implies a non-slip surface with substantially improved safety compared to a slippery dirty surface. By increasing the coefficient of friction (static friction) and decreasing the slipperiness of the floor, dangerous accidents can be reduced.

  The present invention relates to a magazine loading of a solid product by alternately arranging two different solid products in a product housing of a solid product dispenser and a method for discharging a magazine loaded solid product.

  As used herein, “alternately arranged” includes placing at least two different solid products in a desired order including, but not limited to, every other, every second, every third, etc. . The purpose of alternating at least two different solid products is to circulate the use solution produced therefrom through the desired pH range to enhance the overall effectiveness of the system. The exact manner of alternating solid products will depend on the type of circulation desired.

  Any suitable solid product dispenser may be used. Examples of suitable solid product dispensers include US Pat. Nos. 4,426,362; 4,687,121; 4,690,305; and 4,826,661 and US Provisional Application No. 60 / 795,340. What is disclosed. Since such solid product dispensers are well known in the art, only a general description of how such a solid product dispenser will be discussed.

  FIG. 1 shows a solid product dispenser 100 that includes an upper housing part 101 and a lower housing part 111 together with a support member 102 such as a screen supported between the upper housing part 101 and the lower housing part 111. Show. The upper housing part 101 comprises a product housing 103 with a cavity 104 in which a first solid product 150 and a second solid product 160 are located. The support member 102 supports the bottom of the solid product or the product to be discharged. The cover 105 is located on the cavity 104 and protects the first and second solid products 150 and 160. Lower housing portion 111 includes a diluent inlet 112 in fluid communication with spray nozzle 113. Diluent, such as water, is supplied to the diluent inlet 112 via a conduit (not shown) and then sprayed through the support nozzle 102 and onto the bottom 151 of the first solid product 150 via the spray nozzle 113. The The bottom portion 151 may include the bottom surface and the side surface of the solid product 150. A part of the second solid product 160 may be sprayed with a diluent, and a part of the second solid product 160 may be eroded. The diluent erodes a portion of the first solid product 150, and possibly a portion of the second solid product 160, to produce a use solution that passes through the cavity 114, through the use solution outlet 115, and through the outlet conduit 116. Spill into a mop bucket (not shown) or any other suitable container.

  As the first solid product 150 erodes and becomes smaller, a greater percentage of the second solid product 160 is injected with the diluent. Eventually, the first solid product 150 is completely discharged through several spray cycles, and only the second solid product 160 remains and is discharged. When the first solid product 150 is eroded and reduced, or when the second solid product 160 is eroded and reduced, a new first solid product 150 is installed on top of the second solid product 160. Also good. As described above, when the solid product is discharged, the alternate product is installed in the product housing 103, and the product is replenished.

  2-6 schematically illustrate how the solid products 150 and 160 are dispensed through several dispensing cycles. In FIG. 2, the first solid product 150 is shown as it is located within the product housing 103 of the solid product dispenser 100. After several discharge cycles, the first solid product 150 is partially consumed and decreases in size as shown in FIG. When the first solid product 150 is small enough to allow other products to be placed in the product housing 103, the second solid product 160 is placed on top of the first solid product 150 in the product housing 103 as shown in FIGS. 4 may be arranged. The first solid product 150 continues to wear out as shown in FIG. When the first solid product 150 is further consumed and becomes smaller, the transition from the first solid product 150 to the second solid product 160 occurs, and both products are discharged. As shown in the schematic diagram, the erosion of the first solid product 150 does not occur uniformly in a straight line across the bottom surface of the product. The erosion can be non-uniform so that both solid products 150 and 160 can be dispensed substantially simultaneously. In addition, the dispenser can spray the diluent onto the sides of the solid products 150 and 160 so that both solid products 150 and 160 are dispensed substantially simultaneously. When the first solid product 150 is completely depleted, the second solid product 160 remains as shown in FIG. Then, when the second solid product 160 is consumed and is small enough to allow other products to be placed in the product housing 103, a new first solid product 150 is added to the second solid product 150 in the product housing 103. It is arranged on the upper part of 160. This product rotation continues.

  A smaller size solid product is placed in the product housing so that the second solid product does not have to be partially consumed before being placed on top of the first solid product in the product housing. It is recognized that it may be. Alternatively, the product housing may be large enough to accept both solid products.

  When the first solid product 150 is an acidic cleaning product, the second solid product 160 is preferably an alkaline cleaning product. During the transition from the first solid product 150 to the second solid product 160, the pH changes from acidic to neutral (while both solid products 150 and 160 are eroded and discharged) to alkaline. If the first solid product 150 is an alkaline cleaning product, the second solid product 160 is preferably an acidic cleaning product. During the transition from the first solid product 150 to the second solid product 160, the pH changes from alkaline to neutral to acidic.

  While acidic cleaning products and alkaline cleaning products are described herein, it is recognized that other suitable products that provide the advantage of alternating chemical properties may also be used. It is also recognized that more than two products may be rotated in the product dispenser. Any product that can be placed within the product housing of the same dispenser can be used. Preferably, the products do not chemically react with each other. Preferably, the product dispenses at approximately the same speed and utilizes the same dispenser settings, such as pressure, nozzle height, flow rate, temperature, and the like.

  FIG. 7 shows a pH transition over 70 cycles, from an acidic solid product to an alkaline solid product, to an acidic solid product, and each discharge cycle is represented by a filling number. In each fill, 4 gallons of water was used to erode a portion of the product to produce a working solution. The acidic solid product is discharged from the first to the 11th filling, both the acidic solid product and the alkaline solid product are discharged from the 12th to the 27th filling, and the alkaline solid product is discharged from the 28th to the 38th filling Then, both the alkaline solid product and the acidic solid product are discharged over the 39th to 49th filling, and this cycle is started again. The transition from acidic pH to alkaline pH (pH ranging from 6.00 to 8.00) occurred over about 10 fills using a total of about 40 gallons of water. Small or large solid products may be used, and the number of fillings in which each solid product is completely dispensed may vary.

  Rotation through this pH range (acidic, neutral, alkaline, neutral, acidic ...) results in improved cleaning results. Preferably, the acidic use solution has a pH of 3.00 to 6.00, the neutral use solution has a pH of 6.00 to 8.00, and the alkaline use solution has a pH of 8.00 to 11.00. has a pH. Cleaning products having an acidic pH effectively remove polymerized oil stains, whereas cleaning products having an alkaline pH effectively remove newer oil stains. During the transition from acidic pH to alkaline pH, there is a neutral pH, which is effective to remove newer oil stains, but typically not as alkaline pH. Acid cleaning products remove floor buildup that is not effectively removed by alkaline cleaning products, and vice versa. Thus, alternating these products within the product dispenser provides improved cleaning results.

Preferred acidic cleaning products include the ingredients listed in Table 1. Weight percent is the weight of the component relative to the total weight of the composition.

  It will be appreciated that any suitable acidic cleaning product may be used. One example of an acidic cleaning product that may be used is disclosed in US Pat. No. 6,432,906, which is hereby incorporated by reference. Another example of an acidic cleaning product that may be used is disclosed in US Patent Application Publication No. 2005/0197276 A1, which is hereby incorporated by reference.

A preferred alkaline cleaning product comprises the ingredients listed in Table 2. Weight percent is the weight of the component relative to the total weight of the composition.

  It will be appreciated that any suitable alkaline cleaning product may be used. One example of an alkaline cleaning product that may be used is disclosed in U.S. Patent Application ______ (M & G Docket No. 163.2315 US01, entitled “Alkaline Floor Cleaning Composition and Method for Cleaning Floors”), which is incorporated herein by reference. It is incorporated herein. Another example of an alkaline cleaning product that may be used is disclosed in US Pat. No. 5,474,698, which is hereby incorporated by reference.

  Acidic solid product disclosed in U.S. Patent Application Publication No. 2005/0197276 A1 and U.S. Patent Application _____ (M & G Docket No. 163.2315 US01, entitled “Alkaline Floor Cleaning Composition and Method for Cleaning Floors”). Alkaline solid products are available from Ecolab Inc. of St. Paul, Minnesota. By SOLIDSENSE® Floor Care A & B products.

  There are many advantages to simply alternating two different solid products within the product housing of a solid product dispenser. One advantage is that only one step is required to clean the area, and the product is fed into the working solution, so the working solution rotates the pH range to effectively clean various soils. It is. Another advantage is that only one product dispenser is required and the second product is placed in the product housing when the amount of the first product is reduced. In other words, no product selection is required. This eliminates the need to keep track of the product to be used for each cleaning, simply by alternately placing the products in the product housing and using the dispenser in accordance with normal progress, so that the use solution is automatically dispensed. . These advantages are not exhaustive and many additional advantages will be apparent to those skilled in the art.

  The coefficient of friction (hereinafter “COF”) was measured at two separate quick service restaurant locations, location 1 and location 2, on the frying pan, grill, sink, and cut tile floor adjacent to the lobby. The floor of the cut tile was a 4 inch x 8 inch American Olean Q01 Canon Red cut tile. Using the Brunmark Mark II Slip-Tester with a 3 inch x 3 inch Neolite Sensor, the Standard Test Method of the United States of America by the International Institute of Technology, West Consortock Measured according to F 1677-96, under ASTM Standards.

  The first measurement, Measurement A, was obtained from Ecolab Inc., St. Paul, Minnesota. The floor was collected after washing with an acidic washing product according to KADET® Quarry Tile Floor Cleaner. Each floor was washed with a working solution of KADET® Quarry Tile Floor Cleaner prepared in a mop bucket according to the usage on the product label. The working solution was applied to the floor with a mop and then brushed and stirred on the surface of the floor using the mop. A rubber rag was used to guide the working solution into the floor drain, and then the floor was dried. A second measurement, measurement B, was obtained from Ecolab Inc., St. Paul, Minn., Where acid cleaning products and alkaline cleaning products were alternately arranged. SOLIDSENSE (R) Floor Care A & B products according to the principles of the present invention were used to collect the floor after washing the bed. The alternating washed product was used for 8 weeks and measured at 4 and 8 weeks. Typically, one solid product block is used per week, and rotation is performed through acidic, alkaline, acidic, and alkaline use solutions before a typical cycle of 4 week measurements are taken. To be able to be.

  After a quick service restaurant breakfast or lunch work, the Dirty after the quick-tile restaurant's floor may be soiled with fresh oil derived from fried starch or protein food ingredients, and some areas may also contain polymerized oil / Dry measurement was taken. Dirty / Wet measurements were taken under the same environment as Dirty / Dry except that the floor was wetted with water to mimic spills. Clean / Dry measurements are made using typical floor cleaning procedures, using either an acidic cleaning product (Measurement A) or an alternating product of Acid and Alkaline Cleaning Products (Measurement B). Was collected after washing. Clean / Wet measurements were taken under the same environment as Clean / Dry except that the floor was wetted with water to mimic the spilled or moped situation.

  As shown in FIG. 8, the COF was greater after the floor was cleaned with alternating products of acidic and alkaline cleaning products. Therefore, by alternately using acidic cleaning products and alkaline cleaning products, the floor had better static friction and became less slippery.

  The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
