When was the process of filling the bottom with fragrance and then bottling it invented?

The core patent and prototype for filling and bottling with perfume essence were born in 2004, were publicly patented in 2005, entered China in 2007, and became popular domestically after 2013.

Hong Kong Genie-S Company proposed the "bottom pressing filling + one-way valve sealing" solution.

2004-04-20: Submitted US patent (US8079388B2), authorized on 2011-12-10.

2004: Launched the first product Genie-S, resembling a lighter with an inflating feature.

2005: International patent published (technology finalized)

Published international patent WO2005101969A2, the core being "pressing with the positive filling pump head, bottom one-way valve filling, full process sealed without evaporation".

Principle analogy to a lighter inflating: Positive filling pump head = inflating tank, bottom valve = inflating port.

2007: Entered China (patent layout)

Applied for Chinese patent CN200720051806.9, protecting the bottom filling structure and leak prevention design.

Initially entered the domestic market through cross-border purchasing and niche beauty channels, with high prices and low recognition.

2013-2015: Domestic popularity (mass production + price reduction)

After 2013, Chinese factories (such as Yuyao, Dongguan) conducted research and production imitation, with costs significantly reduced.

Products were listed on platforms (Taobao, JD) and prices dropped from hundreds of yuan to less than ten yuan, quickly replacing traditional screw-open models.

2015: Became the mainstream of perfume filling and bottling, brands such as Travalo, Perfume Pod, and Orandi rose.

2019: Structural iteration (function optimization)

2019: "Up and Down Dual Ports" model appeared (CN210018235U), supporting bottom filling + top opening for cleaning.

2022-2024: Patent focus on "glass inner bottle + metal outer frame" "vacuum anti-evaporation" and other detail optimizations.

2. Invention Background: Solving traditional filling and bottling pain points

Traditional top pouring (mainstream before 2000): Opening the cap → Open the container to pour the liquid → Easy spillage, evaporation, and cross-odor; pump head seal was damaged, long-term leakage.

Core innovation of bottom filling (2004):

No opening of the cap: Pump head is not disassembled throughout the process, seal is permanently intact.

One-way valve: Only in, no out, inverted shaking does not leak.

Pressure filling: Utilizing the pressure of the positive filling pump head to press in, no evaporation, no waste.

3. Clarification of Similarities and Differences

This was not invented after 2019: 2019 was an iterative model, the basic patent was in 2004.

It is not a Chinese original: The prototype and basic patent originated from Hong Kong Genie-S, the mainland was for mass production and optimization.
