Problems solved by technology

[0002] In daily life, the use of bottles is very common. Most of the cups sold in the market are used to hold liquids, and the stoppers are only used to cover the cup so that the liquid in the container does not spill out of the cup, so the function of the cup cover is only that. , and the bottle is basically abandoned if the cap is lost. As people's requirements are getting higher and higher, the bottle cap with a single function is difficult to meet people's needs. Therefore, the top cup has begun to enter people's lives, and the existing top cup Most of them use flat top caps, and the clamping between the bottle and the bottle is not firm, which is easy to cause leakage or poor sealing, resulting in product deterioration

Embodiment 1

[0041] According to the composition and parts by weight of the composite rubber sealing ring in the bottle-top cup as follows, the raw materials are weighed: silicone rubber: 50 parts, acrylate rubber (ACM): 30 parts, ethylene-propylene-diene rubber (EPDM): 30 parts Parts, nano-calcium carbonate: 15 parts, plasticizer 3 parts, sulfur: 1 part, zinc oxide: 8 parts, stearic acid: 4 parts, anti-aging agent: 3 parts, wherein, the average particle diameter of the nano-calcium carbonate The average particle size of zinc oxide is 10nm, and the average particle size of zinc oxide is 3μm; mix the weighed raw materials through an internal mixer to form a rubber compound; The material punching die is pressurized, vulcanized, and finally the mold is opened to make the bottle top cup sealing ring. Wherein, the heating temperature is 35° C.; the initial temperature of the mold in the pressure-holding process of the rubber die is 100° C.; the pressure increases step by step during the pressur...

Embodiment 2

[0043] According to the composition and parts by weight of the composite rubber sealing ring in the bottle-top cup as follows, the raw materials are weighed: Silicone rubber: 40 parts, acrylate rubber (ACM): 40 parts, ethylene-propylene-diene rubber (EPDM): 20 parts Parts, nano-calcium carbonate: 25 parts, plasticizer 2 parts, sulfur: 0.5 parts, zinc oxide: 5 parts, stearic acid: 2 parts, anti-aging agent: 4 parts, wherein, the average particle diameter of described nano-calcium carbonate The average particle size of zinc oxide is 8nm, and the average particle size of zinc oxide is 2μm; mix the weighed raw materials through an internal mixer to form a rubber compound; The material punching die is pressurized, vulcanized, and finally the mold is opened to make the bottle top cup sealing ring. Wherein, the heating temperature is 30°C; the initial temperature of the mold in the pressure-holding process of the rubber die is 90°C; the pressure increases step by step during the pres...

Embodiment 3

[0045] Weigh the raw materials according to the composition and parts by weight of the composite rubber sealing ring in the bottle-top cup as follows: Silicone rubber: 60 parts, acrylic ester rubber (ACM): 20 parts, ethylene-propylene-diene monomer (EPDM): 40 parts Parts, nano calcium carbonate: 5 parts, plasticizer 5 parts, sulfur: 2 parts, zinc oxide: 10 parts, stearic acid: 2 parts, antioxidant: 2 parts, wherein, the average particle diameter of described nano calcium carbonate The average particle size of zinc oxide is 20nm, and the average particle diameter of zinc oxide is 5 μm; The raw materials that have been weighed are mixed by an internal mixer to prepare a mixed rubber; then the mixed rubber is thermally kneaded on an open mill to obtain a rubber compound, and then Pressurize and vulcanize the rubber material, and finally open the mold to make the bottle top cup sealing ring. Wherein, the heating temperature is 40°C; the initial temperature of the mold in the rubbe...

Abstract

The invention belongs to the technical field of articles for daily use, and particularly relates to a bottle top cup. The bottle top cup comprises a cup body formed by an inner cup body and an outer cup body; an inner cavity is defined between the inner cup body and the outer cup body; ring-shaped convexes are arranged on the outer wall at the upper end of the inner cup body; convex rings are arranged on the outer wall at the upper end of the outer cup body; the outer cup body is provided with a sealing body; a ring-shaped groove is formed in the sealing body; a ring-shaped sealing ring is embedded in the groove, and protrudes outward to form convex shoulders; the seal ring is made of compound rubber; the compound rubber comprises the following components in parts by weight: 40-60 parts of silicone rubber, 20-40 parts of acrylate rubber, 20-40 parts of ethylene-propylene-diene monomer rubber, 5-25 parts of nanometer calcium carbonate, 2-5 parts of a plasticizer, 0.5-2 parts of brimstone, 5-10 parts of zinc oxide, 2-5 parts of stearic acid, and 2-5 parts of an antiager. The bottle top cup is convenient to use, relatively wide in applying range, relatively good in sealing effect, long in service life, and low in manufacturing cost.
