Taiwan University Invention Makes Coffee Without a Cup

If you’ve ever tried brewing coffee on the go and realized you forgot your reusable cup—or worse, had to buy a disposable one—this new invention is for you. A team of students from Asia University in Taiwan has developed a solution that removes the hassle of finding or carrying a separate cup when you want to make a single cup of coffee anywhere.

Their invention, a foldable coffee brewing package, won a gold medal and a special award at the Seoul International Invention Fair. It allows users to brew and drink coffee without needing any extra container—solving a common pain point for travelers, commuters, and coffee lovers on the move.

What Is This No-Cup Coffee Invention?

The device is called the ''—translated as 'Portable Beverage Brewing Pack That Doesn’t Require a Separate Cup.' Specifically designed to work with ear-hook style drip bags (like those used for pour-over coffee), it integrates a heat-resistant paper cup into the design. The cup is made with fold lines that let it flatten for easy transport. When you’re ready to brew, you simply unfold it into a cup shape, tear one end to pour hot water through the filter, and then tear the other end to drink from.

How Did This Win Big at an International Fair?

This innovation was part of a larger showcase by Asia University, where 14 student inventions competed at the Seoul International Invention Fair. Out of those, five won gold, six silver, two bronze, and one special award. The no-cup brewing pack stood out, earning both a gold medal and a special prize from Thailand. It also attracted strong interest from international companies, including major players from the U.S., Germany, South Korea, and Switzerland. Korean venture capital firms and beverage companies showed particular enthusiasm. A well-known Taiwanese coffee bean company, (Gashen), has already approached the university about technology transfer to bring the product to market.

Why This Matters for Coffee on the Go

For coffee drinkers who value convenience, sustainability, and quality, this invention directly addresses several pain points. It removes the need to carry a cup, reduces waste from disposable cups, and makes single-serve brewing more accessible in places where you wouldn’t normally brew coffee—like on a train, in a park, or at your desk without a mug. The integration with existing drip bag systems, like ear-hook pour-over filters, means it works with proven brewing methods that deliver clean, flavorful extractions.

Other Notable Inventions From Asia University

The university’s success wasn’t limited to the coffee brewer. Other gold medal-winning inventions included:

• A modular roadside barrier system
• An electric kettle-style tea infuser
• A IV tube with extendable tubing for easier access
• A tire tread depth sensor that warns drivers if tires are worn below the legal minimum of 1.6mm
• A device that detects car tire tread thickness using red laser displacement sensors. If the tires are worn below 1.6mm, a red light and alarm alert the driver

These projects reflect the creativity and technical skill of Asia University’s student inventors, covering fields from industrial design to health management and automotive safety.

Frequently Asked Questions

What is the 'no cup' coffee brewing pack?

The 'no cup' coffee brewing pack is a foldable, heat-resistant paper cup integrated with a drip coffee filter bag. It flattens for portability and unfolds for use. You pour hot water through one end, where the filter is, and drink from the other. It eliminates the need for a separate cup when brewing single servings of coffee.

Where was this invention recognized?

The invention won a gold medal and a special award from Thailand at the Seoul International Invention Fair in South Korea. It was one of 14 projects from Asia University, which collectively earned 5 golds, 6 silvers, 2 bronzes, and 1 special award.

Can you use any drip bag with this cup?

The current design is tailored for use with ear-hook style drip filter bags, similar to common pour-over setups. It’s optimized for single-serve manual brewing methods that use standard drip filtration.

Will this product be available commercially?

Yes. A Taiwanese coffee bean company, Gashen, has already initiated discussions for technology transfer, aiming to bring the product to market. International companies have also expressed interest in manufacturing or licensing the design.

Is this only for coffee, or can it brew other drinks?

While designed with coffee in mind, the underlying concept—a foldable cup with an integrated filter system—could potentially be adapted for other single-serve hot beverages like tea.
