Shamrock Cups, LLC designs and develops foodservice packaging using origami folding techniques beginning with…The Integral Cup/LidA single use cup with an integrated folding closure: no plastic lids that create environmental garbage- are not secure on cups, leading to spillage
- are difficult to handle
- prevent more uptake in drive-thru service
- reduce inventory space for retailers.
Revolutionary Concepts- We use the ancient art of origami to design a cup with integral lid closure.
- We are the first to use this art form to advance cup design for a world market.
- We have integrated hot cup insulating sleeves within the cup and lid body.
ResolutionShamrock innovation solves multiple issues: - No more plastic lids (shipping, handling, inventory)
- Speed of service is improved.
- Consumer-friendly integral cup/lids are secure
- Recyclable paper eliminates plastic refuse.
- Compatible with renewable/recyclable bioplastics
Benefits for AdvertisingRetail Sales - Retailers will be "first adopters"
- The “green” factor gives the retailer positive market feedback
- Consumer satisfaction creates a comfort zone for users, thus increasing “GO” cup sales
Usability
- Simple pinch-and-press closure is easily executed
- Positive “pop” provides visual/audio confirmation that cup is securely closed
- Closure is easily opened and closed
- Less spillage in vehicles and on clothing
- No more plastic lids popping off as cups are squeezed.
- Easier for children to handle
Technology- Prior attempts at integrated closures have complex folds and/or insecure locks
- Our unique folding structure offers both simplicity and security
- ...and is patent pending
- Our IP also includes special-purpose design software for retail customization
VariantsStiffness of lock can be continuously varied in design by changing fold curves and angles - Loose for open/reclosability
- Tight for no-spill kiddie cups
Spill Resistance- We have dropped filled cups on their sides from a foot or two height and the closure remains secure
- Greater spill resistance leads to greater customer uptake in drive-through
Straw and Access- Coffee: sipping hole at fold rim
- Sodas: punch-out straw hole, or peel-off covering

Graphics- Cup blank lid and body can be printed in a single step
- Designated fill line graphic is desirable
- Fold pattern offers unique opportunities: the image “comes together” as the cup is closed.
Materials- Current prototypes are made from industry-standard poly-coated paperboard
- We are evaluating a range of eco-friendly and green materials (PLA)(PHA)
- Cup samples from microcellular plastics in 2008
Prototype StatusCurrent prototypes are scored and hand-assembled; however: - Design is compatible with conventional production equipment
- One additional manufacturing step by scoring folds
- Basic closure works with folded rim
- Cups nest to industry standards.
What's Next
- Obtain intellectual property rights worldwide
- Listen to customers/continue market research
- License the innovation to industry
- Create additional packaging designs using origami techniques
