Description
- This patent application is a Continuation of U.S. patent application Ser. No. 12/091,136, filed on Aug. 8, 2008, which is a U.S. 371 patent application filing of International Application No. PCT/US2006/042309, which claims priority to Japanese Patent Application No. 2005-311874, filed on Oct. 26, 2005.
- The present invention relates to a lubricant composition for a resin conveyor used for transporting steel cans, aluminum cans, glass bottles, paper containers, and in particular polyalkylene terephthalate containers in the process of manufacturing and filling tea, coffee, black tea, milk beverages, carbonated refreshing beverages, and seasonings. More particularly, the present invention relates to a lubricant composition for a resin conveyor that excels in washing ability and lubricating ability and prevents stress cracking of polyalkylene terephthalate containers, and to a method for using the same.
- In recent years, containers from polyalkylene terephthalates such as polyethylene terephthalate (referred to hereinbelow as “PET containers”) have been widely used as containers for beverages such as tea, coffee, black tea, milk beverages, and carbonated refreshing beverages.
- Furthermore, in addition to conveyors from metallic materials such as stainless steel, conveyors from resin materials such as polyacetal resins, polypropylene resins, polyethylene resins, acrylonitrile-butadiene-styrene resins, etc. (referred to hereinbelow as “resin containers”) have been used in the processes of manufacturing and filling the beverages.
- Resin conveyors are usually used for transporting PET containers in the process of filling the containers with the above-described beverages.
- Resin conveyors are continuously operated under automatic control. As a result, even when the flow of PET containers is stopped, the resin conveyor alone continuous operating. In this case the dynamic friction force between the PET container and conveyor surface has to be decreased.
- Further, an appropriate static friction force is required for the conveyor surface in order to place the PET containers that were supplied from a washing machine directly onto the flow of resin conveyor.
- For this purpose, Japanese Patent Application Laid-open No. H1-96294 has discloses a lubricant composition comprising a higher fatty acid soap as the main component and optionally a surfactant obtained by compounding a cationic surfactants having Bactericidal ability and a nonionic surfactant. Such lubricant composition is used by diluting with water to a concentration of the higher fatty acid of about 0.01 to 0.1% and supplying onto a conveyor by appropriate method such as coating.
- However, lubricating ability of such lubricants comprising the a higher fatty acid soap as the main component is sometimes affected by hard components of the water used. Thus, such lubricants react with hard components of the water used, producing scale, and this scale accumulates on the conveyor surface and decreases the lubrication thereof. Moreover, microorganisms (fungi) inevitably appear in the scale. Yet another problem is that the nozzles for supplying the lubricant are clogged with the scale. Accordingly, Japanese Patent Application Laid-open No. H2-97592 discloses a bactericidal lubricant for transferring bottles and cans, the lubricant comprising a specific anionic surfactant and a bactericidal quaternary ammonium cationic surfactant.
- Furthermore, if such lubricants adhere to PET containers for carbonated beverages, because the inside of the container is pressurized by the carbon dioxide gas, stresses appear therein causing stress cracking of the PET container. As a result, there is an unavoidable risk that the PET container will be damaged and that the liquid beverage filling the inside of the container will leak.
- Japanese Patent Application Laid-open No. H6-172773 discloses a lubricant for a bottle conveyor for PET containers for a process of filling the containers with a carbonated refreshing beverages, in which an alkyl diphenyl ether disulfonic acid salt is added to a lubricant composition comprising a water-soluble fatty acid alkali salt as the main components, whereby stress cracking of PET containers is prevented or inhibited, while lubricating ability is being maintained.
- Further, as a lubricant for resin conveyors, Japanese Patent Application Laid-open No. H10-158681 discloses a lubricant for a bottle conveyor made from a synthetic resin such as polyacetal resin that comprises as the main component an aqueous solution containing 0.0025 wt. % or more of polyethylene glycol-type nonionic surfactants composed of at least one block copolymer of polyoxyethylene alkyl ether, a polyoxyethylene fatty acid ester, or polyoxyethylene and polyoxypropylene, this lubricant having excellent washing ability and lubricating ability and causing no scale.
- However, the problem associated with polyethylene glycol-type nonionic surfactants with HLB 10 to 16 is that they affect stress cracking of PET containers. Furthermore, there is a need for a compact lubricant composition that can be used with a high dilution ratio
- With the foregoing in view, an object of the present invention is to provide a lubricant composition for a resin conveyor that has excellent washing ability, lubricating ability, and stability in storage and a method for using same. More particularly, an object of the present invention is to provide a lubricant composition for a resin conveyor that is advantageous for transporting PET containers and has excellent ability to prevent stress cracking and a method for using same.
- The inventors have conducted a comprehensive study to attain the aforementioned object, and the results obtained demonstrated that a lubricant for a resin conveyor with excellent washing ability, lubricating ability, and stability in storage can be obtained by using a specific nonionic surfactant as the main component. In particular, the ability to prevent stress cracking is imparted by selecting specific components, thereby making it possible to obtain a lubricant composition for a resin container that is advantageous for transporting PET containers.
- Furthermore, adding a specific cationic surfactant and/or amphoteric surfactant makes it possible to obtain a lubricant composition for resin containers also demonstrating an effect (bactericidal effect) of inhibiting microorganism (fungi) generation, without degrading the washing ability, lubricating ability, ability to prevent stress cracking, and stability in storage.
- Furthermore, using such lubricant compositions for resin conveyors makes it possible to provide a method of use that is advantageous for transporting PET containers. Those findings led to the creation of the present invention.

- In accordance with the present invention, using a specific nonionic surfactant as the main component makes it possible to obtain a lubricant composition for a resin conveyor that has excellent lubricating ability, washing ability, and stability in storage and is also capable of preventing stress cracking when transporting not only steel cans, aluminum cans, glass bottles, and paper containers, but also PET containers.
- Furthermore, adding a specific cationic surfactant and/or amphoteric surfactant makes it possible to obtain a lubricant for resin conveyors that also demonstrates an effect (antibacterial effect) of inhibiting microorganism (fungi) generation, without degrading the washing ability, lubricating ability and stress cracking prevention effect.

- The nonionic surfactants (A) can be used individually or in combination of two or more thereof. The compounding ratio thereof is set to 0.0025 to 30 wt. % in the lubricant composition. Thus, if the compounding ratio is less than 0.0025 wt. %, the desired lubricating ability cannot be obtained. If the compounding ratio is above 30 wt. %, stability of the lubricant composition in storage (−0° C.) cannot be obtained. Another undesirable consequence is that the composition easily becomes foamy due to disrupted balance with other components.

- In accordance with the present invention, the cationic surfactant (a) and/or amphoteric surfactant (b) can be used as the component (C), and the (a) and/or (b) of one type each or of two or more types each may be used.
- The compounding ratio thereof is set to 0.001 to 30 wt. %, as an effective component quantity, in the lubricant composition. Thus, if the compounding ratio is less than 0.001 wt. %, the desired antibacterial effect cannot be obtained. Furthermore, if the compounding ratio exceeds 30 wt. %, the desired stability of the lubricant composition in storage cannot be obtained due to disrupted balance with other components. Furthermore, this is cost inefficient.
- The weight ratio of the nonionic surfactant that is the component (A) and amphoteric surfactant (a) and/or amphoteric surfactant (b) that is the component (C) is A:C=5:1 to 1:30, as the effective component quantity, in the lubricant composition. Furthermore, the content of the [component (A)+component (C)] in the lubricant composition is 0.0035 to 60 wt. %.
- When the A:C weight ratio is above 5:1 and the lubricant composition contains a large quantity of the component (A), the bactericidal effect is poor, and when this ratio is more than 1:30 and the lubricant composition contains a large quantity of the component (C), the ability of the lubricant composition to prevent stress creaking is degraded. Furthermore, the lubricant composition has poor stability in storage due to disrupted balance with other components and cost efficiency is poor.
- Furthermore, it is undesirable that the content of the [component (A)+component (C)] in the lubricant composition be less than 0.0035 wt. % because the desired lubricating ability cannot be obtained. Furthermore, if this content exceeds 60 wt. %, the desired stability of the lubricant composition in storage cannot be obtained due to disrupted balance with other components and the composition is cost inefficient.
- If necessary, the lubricant composition in accordance with the present invention can contain a water-soluble solvent, other bactericidal agents, an anionic surfactant, an antifoaming agent, an additive increasing the clouding point, a washing builder, and the like. Among them, examples of water-soluble solvents include propylene glycol, monoethanolamine, hexylene glycol, diethylene glycol monobutyl ether, ethyl alcohol, isopropyl alcohol, and isoprene glycol. Such a solvent is compounded as a solubilizing agent of the lubricant composition or as a neutralizing agent for acidic components. Furthermore, examples of the anionic surfactant include polyoxyethylene alkyl ether phosphoric acid or polyoxyethylene alkyl ether carboxylic acid and alkali salts thereof. Examples of washing builders include ethylene diamine tetracetic acid, nitrilotriacetic acid, citric acid, malic acid, gluconic acid, iminodiacetic acid, and alkali salts thereof.
- When the lubricant composition for a resin conveyor in accordance with the present invention is used, it is employed as a diluted solution of a lubricant that is obtained by diluting with water or hot water so as to obtain an effective component concentration of the component (A) of 25 to 1000 mg/L, for transporting PET containers.
- Dilution of the lubricant is usually carried out by using water, and lubricant composition may be used after diluting to the desired usage concentration or a solution diluted to an appropriate concentration may be prepared in advance and then this solution may be further diluted to the desired usage concentration at the time of use.
- The diluted solution of the lubricant that was thus prepared can be supplied on a conveyor from a spraying nozzle via a pump or the like, coated by spraying, or applied with a brush or the like.
- Employing a method of using by which the diluted solution of the above-described lubricant composition for conveyor and at least one species selected from aqueous solutions of a hypochlorite, peracetic acid, hydrogen peroxide, and iodine at 5 mg/L or more, or chlorine dioxide at 0.05 mg/L or more, are supplied, sprayed, or applied on a conveyor, in a mixture or separately, and used for transporting PET containers makes it possible to provide an even higher bactericidal effect, without decreasing excellent lubricating ability, washing ability, and ability to prevent stress cracking.
- As described above, an important feature of the present invention is that it uses a specific nonionic surfactant with HLB above 16.
- Furthermore, since the lubricant composition in accordance with the present invention contains no fatty acid soap as the main components, by contrast with conventional lubricant compositions, the advantage thereof is that water quality (mineral components such as calcium and magnesium) of water or hot water used for diluting the lubricant composition and quality of material used produce not effect.
- Providing for excellent lubricating ability, washing ability, and stability in storage, and in particular the ability to prevent stress cracking, makes it possible to obtain a lubricant for a resin container that is advantageous for transporting PET containers.
- Adding a specific cationic surfactant and/or amphoteric surfactant makes it possible to obtain a lubricant for a resin conveyor that additionally demonstrates the effect (bactericidal effect) inhibiting microorganism (fungi) generation.
