Package usability assessment has become increasingly critical as products diversify and user expectations evolve. Current data shows that up to 40% of consumer complaints about products stem from packaging-related issues, with particular challenges in areas like opening mechanisms, content extraction, and resealing functionality. These usability concerns directly impact both user satisfaction and product integrity.

The fundamental challenge lies in balancing secure product protection with intuitive, accessible user interaction across diverse demographic groups and usage scenarios.

This page brings together solutions from recent research—including flexible tab retention systems, curved interior surfaces for controlled dispensing, demographic-specific visual indicators, and integrated resealable extraction mechanisms. These and other approaches demonstrate how thoughtful design can enhance both product protection and user experience while maintaining manufacturing feasibility.

1. Cosmetic Packaging with Sleeve-Engaging Relief Mechanism for Refill Retention

PARFUMS CHRISTIAN DIOR, 2025

Refillable cosmetic packaging device that prevents using the refill without the case to maintain product protection. The device has a cosmetic product refill with a rotatable sleeve around the cap. The device housing has a complementary relief shape to engage with the sleeve relief. This connection prevents rotating the sleeve without the housing, making it harder to use the refill alone. The housing provides protection that the refill lacks.

2. Packaging Design with Shape Maintenance, Opening Condition Indicators, and Demographic-Specific Illustrations

UNI-CHARM CO LTD, ユニ・チャーム株式会社, 2024

Packaging design that makes it easier for users to choose and use the right products by providing clear indicators of intended use and target users. The packaging has features like shape maintenance, clear condition after opening, and illustrations that match the product's intended use and user demographics. This reduces the risk of mistaken selection or misuse.

3. Two-Piece Cosmetic Container Cap with Flexible Skin and Internal Ribbed Locking Mechanism

LOREAL, 2024

A packaging and dispensing assembly for a cosmetic product that improves the design of the cap on the product container. The cap has a two-piece construction with a flexible skin connected to a rigid frame. This allows the cap to snap onto the product container without visible snap-on grooves. The cap also has a ribbed structure on the inside that locks onto the container when assembled. The cap can be easily removed by pressing the tabs on the ribbed structure. This provides a better sealing and retention mechanism compared to traditional snap-on caps.

4. Cosmetic Packaging with Flexible Tab and Rotatable Ring Refill Retention System

LOREAL, 2024

Refillable cosmetic packaging with improved refill retention and easier refill swapping. The packaging has a cover assembly with flexible tabs around it, and a removable refill container with an axial holding ring. The ring engages the tabs to hold the refill axially in the cover. Rotating the ring in one direction locks it, preventing accidental refill ejection. Rotating the ring in the opposite direction releases the refill. This provides secure retention and easy refill swapping. The tabs prevent clearance between the refill and cover, improving quality perception. The ring engages the tabs to indicate it's locked.

5. Lid for Sheet Material Package with Central Hole and Curved Slits for Controlled Single-Sheet Dispensing

レック株式会社, LEC INC, 2024

Lid for a sheet material package like a wet tissue box that allows pulling out one sheet at a time without multiple sheets coming out together. The lid has an extraction hole with a central hole, left and right slits, and curved slits connecting them. When pulling a sheet, the curved slits provide resistance preventing multiple sheets from being pulled simultaneously. The central hole allows easy extraction, while the slits slow down the sheet exit. This prevents accidental pulling of multiple sheets at once. The lid also has a rotating part to open/close the lid.

6. Oral Smokeless Tobacco Pouch with Rounded Corners and Arcuate Seam Structure

IMPERIAL TOBACCO LTD, 2024

Smokeless tobacco pouches for oral consumption that improve user comfort by having rounded corners instead of sharp corners. The pouch has discrete seams at each end. The inner seam has an arcuate portion proximal to the pouch, and the outer seam has an arcuate portion distal to the pouch. This provides a more consistent seal strength and prevents sharp corners from contacting the user's mouth when placing the pouch. The rounded corners improve mouthfeel compared to sharp corners. The pouch can be made by forming sheets around the content, sealing them, and then cutting the rounded corners.

12. Integrated Elastic Latch Mechanism for Packaging Box Covers Using Homogeneous Material Construction

LEESUNRYE, 이선례, 2024

A cover opening and closing mechanism for packaging boxes that allows easy opening without separate release buttons or devices, while reducing manufacturing costs by using the same paper material for the cover and box. The mechanism involves an elastic piece inside the box that connects to the cover when closed. When the cover is forced upward, the elastic piece deforms and separates from the cover groove, allowing the cover to open. This prevents accidental closure. When closed normally, the elastic piece restores and clicks into the cover groove. The cover can be easily opened by pressing it onto the box.

함지혜, 2024

Disposable bottle with one-touch removal of elastic wrapping band. The bottle has a lid and main body. An elastic wrapping paper is wound around the bottle between the lid and body. The wrapping paper has a perforation line. When the lid is rotated, the perforation line gets cut and the wrapping paper separates from the body. The lid and body have recessed grooves that match the width of the wrapping paper. This allows the paper to be inserted and held securely. The recessed grooves prevent protrusion when the paper is cut. This enables easy one-touch removal of the paper after opening the bottle.

15. Closure System for Reusable Pouch with Elastomeric Interdigitating Profiles Providing Auditory and Tactile Feedback

S C JOHNSON & SON INC, 2024

Reusable pouch with a closure system that provides auditory and tactile feedback when opening and closing the pouch. The closure has an elastomeric male closure profile with oversized regions that interdigitate with the female closure profile. This creates a snap when closing that indicates a tight seal. The oversized regions provide tactile feedback and the snap provides audible feedback. The intermittent interdigitations prevent the male from fully retracting, requiring the snap to fully engage for a tight seal.

16. Packaging Case with Rotatable Pressing Unit and Flexible Buckle Mechanism for Secure Item Retention

The box has a scent source inside that releases a scent associated with the joy of receiving a gift. This scent can trigger memories of the gift-giving occasion every time the person approaches or opens the box. It can also help promote the use of related products like perfume since the scent dissipates over time and needs to be replenished.

19. Pouch with Horizontal Side Seals Incorporating Finger Cutouts for Enhanced Grip

株式会社フジシール, FUJI SEAL INC, 2024

Pouch with a spout that can be easily held with one hand when the pouch becomes larger. The pouch has a unique design for the side seals to facilitate grip. Instead of traditional side seals that run vertically along the pouch edges, the side seals extend horizontally along the top and bottom of the pouch.
