Product Information
A sauce bottle cap is a specialized closure designed for bottles containing sauces and condiments such as ketchup, chili sauce, BBQ sauce, salad dressing, and syrups. Its primary function is to securely seal the bottle while ensuring clean, controlled, and convenient dispensing.
Hopewell offers a sauce dispensing cap from our existing mold with a 33/400 neck finish and 35 mm outer diameter. The sauce bottle cover is manufactured from food-grade PP and liquid silicone, using advanced plastic injection molding and LSR (Liquid Silicone Rubber) injection molding processes.
The sauce bottle cap is integrated with a silicone one-way flow valve, delivering precise flow control, excellent sealing performance, and reliable leak-proof protection.
Squeeze bottles are widely used for sauces and condiments, but traditional bottle caps often lead to leakage, mess, and poor dispensing control. Hopewell squeeze sauce bottle caps with silicone valve are engineered to solve these common problems and deliver a cleaner, more reliable dispensing experience.
Common Issue | Hopewell Design Solution & Key Feature |
Leakage after squeezing | The integrated silicone flow control valve offers excellent sealing performance, immediately closing after pressure release to prevent leakage. |
Messy bottle mouth | A clean cut-off silicone valve design ensures precise shut-off after dispensing, keeping the bottle mouth clean. |
Inconsistent dispensing | Engineered flow rate control delivers smooth, consistent, and controlled dispensing with every squeeze. |
Poor sealing during transport | A tight sealing structure, verified through drop testing, ensures reliable sealing during transport and handling. |
Multiple or Uncontrolled Streams | The extrusion angle is precisely controlled within ±15 degrees, ensuring a single, focused dispensing stream. |
Poor Air Return Performance | The silicone check valve features a uniform wall thickness and a precisely centered cross-slit cut, enabling fast air return and allowing the bottle to quickly recover its original shape after squeezing. |
Sauce Waste | The sauce bottle cap features a built-in cross slit valve that allows smooth, controlled dispensing and helps squeeze out every last drop, maximizing sauce usage and reducing waste. |
Sauce spoilage | The sauce bottle cap with a silicone one-way valve ensures reliable sealing and controlled dispensing. The silicone valve opens only when squeezed and closes instantly after release, blocking air entry to help preserve freshness and reduce spoilage. |
The 35 mm sauce bottle cap is designed to provide controlled dispensing, excellent sealing, and reliable leak-proof performance, making it suitable for a wide range of packaging applications.
Flip top sauce bottle caps are commonly used on bottles with capacities ranging from:
50 ml – 100 ml: Travel-size or sample packaging;
150 ml – 300 ml: Retail and household condiment bottles;
350 ml – 500 ml: Standard squeeze bottles;
The sauce bottle cap with silicone valve structure supports smooth dispensing across small to large volumes, especially when paired with squeeze bottles.
While the flip sauce bottle cap itself fits various bottle designs, the bottle must be squeezable for optimal silicone valve performance.
Inverted (upside-down) bottles
Boston round bottles – Rounded shoulders, easy squeezing
Cylindrical bottles – Straight walls, stable grip
Oval or ergonomic contour bottles – Enhanced handling comfort
Flexible bottles provide the best user experience, as squeezing directly controls flow through the silicone one-way valve.
Sauce Viscosity | Examples | Benefit of Plastic Valve Cap |
Medium to High Viscosity | Ketchup, mustard, mayonnaise, BBQ sauce, thick salad dressings, curry paste etc. | Provides controlled flow, prevents glugging, and ensures a clean break. |
Low Viscosity (Liquid) | Soy sauce, vinegar, hot sauce, liquid dressings, cooking oil etc. | Prevents leakage and accidental spills with automatic silicone check valve sealing. |
Sauces with Particulates | Chili garlic sauce, Soybean paste, fruit preserves, relish etc. | Reduces clogging compared to traditional open caps. |
