Description

Technical Field

[0001] This utility model relates to a novel silicone sealant packaging bottle specifically for foreign trade export, belonging to the technical field of silicone sealant bottles. Background Technology

[0002] Silicone sealant is a high-performance sealing material with characteristics such as high temperature resistance, weather resistance, good elasticity, and high tensile strength. It can form strong adhesion on various material surfaces and is widely used in industries such as construction, automotive, electronics, and home decoration. Currently, the packaging bottles used for silicone sealant mainly operate based on the principle of air pressure, similar to squeezing toothpaste: applying external force to the bottom of the bottle reduces the internal space, and under the action of pressure difference, the silicone sealant is extruded through the outlet.

[0003] A bottle package consists of a cap, a body, and a sealing structure. The cap and body are typically made of plastic, such as high-density polyethylene (HDPE). The body is generally cylindrical for easy gripping and handling. The cap is a standard threaded, cylindrical protrusion that is opened by cutting with a knife. The sealing structure, located at the junction of the bottle bottom and body, is usually a sealing gasket, generally made of rubber or silicone. Its function is to ensure that the silicone sealant inside the bottle does not leak during normal storage and short-distance transportation, maintaining its airtightness.

[0004] The main problems with existing silicone sealant packaging bottles are:

[0005] 1. Existing silicone sealant packaging bottles use rubber or silicone sealing gaskets. While these materials offer good initial sealing performance, prolonged contact with silicone sealant accelerates gasket aging. This is especially noticeable with acidic silicone sealant, where obvious signs of aging (gasket hardening, loss of elasticity) may appear after 6-8 months of storage, leading to problems such as silicone sealant leakage and drying. For silicone sealant products intended for export, the excessively long sea transport time (often 1-2 months) severely compresses the shelf life of the silicone sealant and threatens product quality.

[0006] 2. Storage environment has a significant impact on the aging of sealing gaskets: High temperature and high humidity environments may cause sealing gaskets to absorb moisture, leading to expansion or mold growth and reduced sealing performance; while silicone sealant products that need to be exported have longer storage and transportation cycles and face more complex environments with greater changes in air pressure, temperature and humidity, which further aggravates the aging of sealing gaskets.

[0007] 3. The existing sealing structure has design flaws: the sealing surfaces of the bottle body and bottom are not smooth enough, making it difficult to guarantee a complete seal even with a high-quality gasket. In actual production, due to limitations in injection molding technology and cost control, there are slight unevennesses on the bottom sealing surface, preventing the sealing gasket from fully adhering to the bottom sealing surface, leading to silicone sealant leakage and drying.

[0008] 4. Impact of transportation vibration: During transportation, vibration and bumps are unavoidable, especially in countries with poor roads. Long-distance truck transport and strong vibrations may cause the sealing gasket to shift. The originally tightly fitted sealing gasket may partially detach from the sealing surface, resulting in seal failure.

[0009] 5. Leakage caused by pressure changes: In countries where foreign trade exports are made, there are significant differences in local temperature and air pressure. When the air pressure suddenly drops, the pressure inside the bottle increases. If there are minor defects in the sealing structure, it will generate additional pressure on the sealing structure, causing the silicone sealant to be squeezed out and leak, or dry out. Utility Model Content

[0010] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a new type of silicone sealant packaging bottle for foreign trade export, which has a reliable sealing structure and a certain pressure resistance to prevent silicone sealant leakage and can withstand the squeezing, collision and other situations that may occur during international logistics transportation; at the same time, it can maintain the stable physical properties of silicone sealant in various climatic environments such as high temperature, humidity and cold, to ensure that the quality of silicone sealant is not affected, and to meet the packaging needs of silicone sealant in international transportation and sales.

[0011] This utility model discloses a novel silicone sealant packaging bottle specifically for export. The bottle body has a cavity at its bottom, within which a support ring is placed. The support ring supports the bottle body and prevents it from being deformed by pressure. The cavity at the bottom of the bottle body is filled with an inert gas, forming an additional sealing barrier to prevent the silicone sealant from curing upon contact with air, thus enhancing the sealing effect. A sealing film is adhered to the bottom of the bottle body, creating a completely enclosed space inside the bottle and isolating the silicone sealant from the external environment. A bottom cap is also installed at the bottom of the bottle body, with a sealing gasket between the sealing film and the bottom cap. After the bottom cap is installed, the sealing gasket adheres tightly to the bottom of the bottle under pressure, forming a secondary seal.

[0012] The technical solution of this utility model is to provide a new type of silicone sealant packaging bottle for foreign trade export. The bottle body is supported by a support ring to prevent it from being squeezed and deformed during transportation. A secondary sealing structure is formed by setting a sealing film and a sealing gasket to effectively prevent silicone sealant leakage. At the same time, a bottom cap is set to prevent the sealing structure from failing or breaking in high temperature, humid, and cold environments, ensuring that the quality of the silicone sealant is not affected.

[0013] Preferably, the support ring is a ring structure with a support rib at the center.

[0014] Preferably, the sealing film is heat-sealed to fit tightly to the bottom of the bottle; the sealing film has a certain strength and can withstand a certain amount of pressure and friction to prevent damage during handling and transportation due to collision or friction; the sealing film can also prevent silicone sealant leakage caused by changes in internal pressure due to temperature changes during transportation, providing reliable additional sealing protection for silicone sealant bottles throughout the entire supply chain.

[0015] Preferably, the bottom of the bottle body is provided with external threads, and the bottom cap is provided with internal threads, and the bottom cap is threadedly connected to the bottle body; the bottom cap is made of high-strength plastic material, which has good pressure resistance and wear resistance.

[0016] Preferably, the shape of the sealing gasket matches the sealing area at the bottom of the bottle; the diameter of the sealing gasket is larger than the opening at the bottom of the bottle; the sealing gasket is made of highly elastic rubber or silicone material, and has excellent flexibility and sealing performance; the sealing gasket can completely cover and tightly fit the bottom of the bottle when subjected to pressure.

[0017] The advantages of this utility model compared with the prior art are:

[0018] 1. The secondary sealing structure at the bottom of the bottle of this utility model can effectively prevent silicone sealant leakage, ensure that product quality is not affected, and reduce the risk of cargo loss and environmental pollution caused by leakage. For exported silicone sealant products, it can effectively avoid leakage problems caused by long storage and transportation cycles and large changes in air pressure, temperature and humidity, providing additional safety for the product throughout the entire supply chain.

[0019] 2. The secondary sealing structure design provides higher standards and reliability in product sealing performance, while also making it easier for customers to observe the integrity of the packaging, which helps to enhance the product's competitiveness in the foreign trade export market.

[0020] 3. This utility model can adapt to different transportation methods. The internal support structure of the bottle and the secondary sealing structure at the bottom of the bottle are not limited by the transportation method and can maintain stable performance in various transportation environments. Even if the sealing gasket may fail to seal due to pressure changes, the sealing structure at the bottom of the bottle can still ensure the sealing of the bottle and ensure the safe transportation of the product to its destination.
