Conventional disposable cups for beverages such as coffee, tea, coffee, alcohol, and beer are made by pressing paper or extruding thermoplastic resin into a sheet using an extruder, and then forming the resulting sheet into a secondary mold. It is made. In addition, this disposable pot is made by adding a foaming agent and a nucleating agent to a thermoplastic resin, such as polystyrene, to enhance its heat-retaining and cold-retaining functions.This mixture is then put into an extruder and extruded under heat and pressure. It is made by extruding the foam into a low-pressure zone through a die attached to it, and then secondary molding it. Although these disposable pots made from thermoplastic resin sheets and foams have passed the PL standard, they do not have antibacterial properties, so there is a possibility that they may be contaminated by bacteria during transportation and storage. Therefore, if drinks are to be put into these disposable cups for hygiene reasons, the disposable cups must be thoroughly washed and sterilized.

開発され、その一部は市場にも出廻つている。 Therefore, it has become important to ensure that these plastics themselves are sterilized at all times, and recently antibacterial agents and antibacterial agents have been introduced that can be mixed into plastics (films and sheets) or applied to their surfaces. Many fungicides, fungicides, etc. have been developed, and some of them are on the market.

However, disposable cups that use plastic as a material that has antibacterial and sterilizing effects by mixing antibacterial agents into the plastic or applying it to the surface are, for example, elution type, and the antibacterial agents eluted from these plastics are Because antibacterial properties are exerted by agents, there is a risk that the taste of the drink may change. In addition, plastics are processed at temperatures of 250°C or higher, and conventional antibacterial agents, especially organic ones, decompose and their antibacterial effects are diminished. Furthermore, in order to obtain the desired antibacterial and sterilizing properties, it is necessary to add a considerable amount, for example, 2.5% or more, based on the weight of the plastic. , the inherent physical properties of plastics are impaired. That is, transparency, slip resistance, heat seal strength, air permeability, etc. are affected, and problems arise in processability.

出荷時点で滅菌状態であつても輸送、保管の時点
で、汚染される危険性がある等の問題点がある。 Because of the above-mentioned problems, disposable pots made of plastic with antibacterial agents mixed into the plastic or coated on the surface are rarely used. For this reason, it is currently necessary to wash and disinfect disposable cups before pouring drinks into them at parties, outdoor barbeques, camps, and other events. There may be times when it is not possible to perform these tasks. Therefore, the sanitary condition is left up to the other party, and there may be cases where the person is defenseless. That is, even if these disposable cups are sterile at the time of shipment, there is a risk of contamination during transportation and storage.
そこで、本考案は上記事情に鑑みてなされたも

良好な無菌性使い捨てコツプを提供することを目
的とする。 Therefore, this invention was developed in view of the above circumstances, and it is possible to exhibit antibacterial properties without eluting antibacterial agents, etc., and to maintain the amount of antibacterial components added without decomposing even at the temperatures required for plastic processing. To provide a sterile disposable pot that requires less water, maintains antibacterial properties for a long period of time, does not require special cleaning, disinfection, etc. before use, and is easily processed.

In order to solve the above problems, the sterile disposable cup of the present invention has at least the inner surface of the pot made of an antibacterial material mainly composed of resin and antibacterial zeolite, and the antibacterial material is It is a multilayer sheet in which at least one thermoplastic resin sheet is fused or adhered to a sheet containing the antibacterial zeolite in a range of 0.1 to 5% by weight based on the total weight of the thermoplastic resin.

Each ion of sodium, potassium, magnesium, iron, etc., n is the valence of the metal ion, X is the coefficient of the metal oxide, Y is the coefficient of silica, and Z is the number of molecules of crystal water. The general formula like this XM 2 / o
The ion exchange capacity of zeolite expressed as O・Al 2 O 3・YSiO 2・ZH 2 O is 2.6 meq/g ~
It is 11.5meq/g. Therefore, in the antibacterial zeolite 6, the ion-exchangeable ions are replaced with antibacterial metal ions such as silver, copper, or zinc. And antibacterial zeolite 6
From the viewpoint of antibacterial properties, it is desirable that these antibacterial metal ions be contained in the zeolite in an amount of about 0.1 to 15% by weight (expressed as weight% on a dry basis at 110°C).

(See ``Antibacterial Zeolite'' filed on December 4, 1988, claiming priority under the provisions of Article 42-2, Paragraph 1 of the Patent Law (Japanese Patent Application Laid-Open No. 63-265809)). The reason why ammonium ions are added in this way is to effectively prevent discoloration of the antibacterial zeolite 6, and it is preferable that the ammonium ions in the antibacterial zeolite 6 be in the range of 0.5 to 2.0% by weight. Furthermore, from the viewpoint of substantially preventing discoloration of the thermoplastic resin 5', the content of the antibacterial zeolite 6 containing ammonium ions is 0.1 to 3.0% with respect to the thermoplastic resin 5'. is preferred.

Next, take out the lids 3 that are also stored in a stack, put this lid 3 on the container body 2 containing the drink, fit the fitting part 12 of the lid 3 into the protrusion 4 of the container body 2, and then insert the lid 3 into the container body 2. To prevent a lid body 3 from being easily removed from a lid body 2. At this time, since the inner surfaces of the container body 2 and lid 3 of the sterile pots 1 stored in stacks have antibacterial properties, if these are not particularly contaminated by dirt, dust, etc., the inside of these sterile pots 1 will be in a sterile state. There is no need to clean or sterilize the sterile tip because it is maintained at
Drinks can be put into the sterile cup 1 in that state. Moreover, the container main body 2 and the lid body 3 are
It has heat and cold retention properties, so even if you hold it in your hands, your hands won't get hot or cold. In particular, when the container body 2 and the lid 3 are made of the foam 11, it is possible to obtain extremely high heat retention and cold retention properties as well as antibacterial properties.

As described in detail above, according to the sterile disposable tip of the present invention, the strength of the tip is achieved by the thermoplastic resin sheet, and the antibacterial property is achieved by the bactericidal ions of the antibacterial zeolite in the sheet. It is possible to kill the microorganisms attached to the container and keep the inner surface of the container sterile. Therefore, although the structure is simple, even if the pot is stored for a long period of time, the pot can be kept in a sterile state, making it easy to manage the hygiene of the pot, and preventing dirt such as dirt and dust from adhering to the pot. If you store the cup in such a way that it won't get wet, you won't need to wash or disinfect the cup before filling it with drinks. Since antibacterial substances do not elute or vaporize from antibacterial zeolite like conventional disinfectants, the antibacterial substances do not change the taste of foods, and there is no disinfection caused by the antibacterial substances. Antibacterial effect lasts for a long time (semi-permanent).
又、抗菌性ゼオライトは、熱に対して強いか
ら、熱による影響を受けにくく、コツプの製作時
に550℃以上の温度がかからなければ、その抗菌
効果が薄れることがない。 In addition, antibacterial zeolite is resistant to heat, so it is not easily affected by heat, and its antibacterial effect will not fade as long as the temperature of 550 degrees Celsius or higher is not applied during the production of the pot.

果がある。 Furthermore, since the amount of antibacterial zeolite added can be small in order to obtain the desired antibacterial and sterilizing properties, it is possible to maintain good processability without impairing the inherent physical properties of the resin, etc. At the same time, it also has the advantage of being able to maintain its economic efficiency.
