Tamper Evidence Technologies for Package Security

Packaging inspection device that can detect leakage of contents from sealed bags without applying voltage or using gas filling equipment. The device has a contact device that touches the bag and a fluorescence detection device that checks for leaked fluorescent material. When contents leak from a punctured bag, they attach to the contact surfaces. The fluorescence detector finds the leaked fluorescent material on the contact surfaces, indicating a leak. This prevents new holes by avoiding voltage and allows accurate leak detection regardless of bag or contents color.

A packaging container with a cap that automatically cuts the sealing membrane when opened, eliminating the need for separate cutting tools. The cap has protrusions that engage guides in the container body. As the cap is removed, the protrusions cut the sealing membrane around the opening. The guides have a shape that causes the protrusions to penetrate and cut the membrane. This allows the container to be opened without separate cutting tools and prevents membrane fragments from contaminating the contents.

A cardboard packaging box with tamper-evident opening features that allows traces of opening during logistics to be confirmed from the appearance of the box and that can be stacked stably. The box has a main body with an open top and a lid plate, upper flaps connecting the side panels above the opening, and an insertion piece between the front panel and the upper flap. A locking piece folds inside the insertion piece and engages the underside of the upper flap when inserted. This locks the lid closed. If the box is opened, the locking piece remains inside and leaves a visible opening trace. The box also has weakened areas on the lid plate to indicate forced opening.

Closure for spouted pouches that provides a comfortable user experience, prevents dispersion of the cap after opening, and enables easy closure after use. The closure has a screw-on cap with a flange extending radially. A tamper evident ring with wavy ridges snaps onto the spout. The cap connects to the ring via a strap that stays attached after the seal is broken. This keeps the cap from falling off and prevents scattering. The wavy ridges break when unscrewing but the strap remains.

A reclosable opening device for packaging of pourable products like juice or milk that provides tamper evidence and enables rotation of the cap to indicate if the container has been opened before. The device has a spout, closing element, and cap that are molded directly onto the packaging material. The cap engages the spout to seal the opening initially. Rotation of the cap is restricted due to geometry. If the cap can rotate freely, it indicates the container has been opened before.

An ink bottle with a unique thread design to prevent ink leakage if the lid is dropped or impacted. The thread on the bottle neck is divided into two separate spirals that form a continuous shape when viewed from the side. This split thread configuration allows the lid to separate cleanly from the bottle if impacted, preventing cracking or deformation that could leak ink. The split thread also has recesses between the spirals that create a continuous path for the thread to follow, preventing any gaps or gaps between the threads that could leak ink.

Reusable, returnable packaging for LED flat lights that enables tracking and monitoring of product condition during transport. The packaging has sensors inside to detect impacts and light levels. A smart label attached to the packaging records this data. By tracking changes in impact and light over the supply chain, issues like damage or opening of the lights can be identified and addressed. This improves delivery stability and prevents returns due to damaged products. The reusable packaging also protects the lights from vibration and shocks. It has an inner case with cushioning and a cover. An outer bag wraps the case for further protection. The lights are packaged without shaking. The smart labels can be scanned to retrieve usage history and number of reuses.

Method and packaging device for efficient and effective error handling in automated pouch filling machines for medicines. The method involves printing indicators on the web as the medicaments are fed into it. If errors are detected, fault indicators are printed on the web. The operator can then easily see and locate faulty pouches. This allows immediate intervention to discard faulty pouches without extensive retracing. The device has a web drive, printing station, and filling station.

A method to create optically machine-readable identifiers on packaging films that cannot be easily copied or manipulated. The method involves generating an identifier by focusing a light beam onto a photosensitive layer on the film. This absorbs the light and causes a color change in the layer. The identifier can be read using a camera. A second layer is added that contains an optically detectable image. The user is asked to scan this image after scanning the identifier. The scanned images are compared and if they match, it indicates the packaging has not been tampered with.

Automated system for in-line sealing defect detection and expulsion of heat-sealed containers like food packaging. The system uses sensors to measure internal container pressure during inflation testing. If the pressure drops below a threshold, indicating a seal defect, the container is expelled from the line. This allows 100% sealing quality control without stopping the production line.

Bottle-type can with improved tamper evidence and sealing properties for beverage containers. The can has a curled opening with a unique shape to prevent deformation and maintain integrity when the cap is tightened. The curl portion has an upper R section curved outward, a lower R section inward, and a retreat surface between them with a larger radius than the lower R. This prevents deformation when loaded from above. The upper R section is shorter than the diameter section. The shape avoids expanding the curl, keeps the liner adhered, and prevents gaping when the cap is tightened.

Vacuum chamber for assessing the airtightness of packaged products like food items that cannot be tested by applying external pressure due to fragility concerns. The chamber uses sensors to detect deformation of the packaged product inside as vacuum is applied to assess seal integrity. This allows automated, high-speed testing of production lines compared to manual visual inspection. Sensors like cameras, distance sensors, and load cells measure product deformation as vacuum is applied to reveal leaks.

Packaging structure for lead-acid batteries that reduces damage and leakage when the outer box is dropped. The structure uses a pulp molded cushioning body inside the outer box that absorbs impacts and leaked electrolyte. The cushioning body has a recess spaced away from the corner of the inner box to prevent concentration of impact at the corner. This reduces the risk of battery damage when the outer box falls corner-first. The cushioning body also absorbs leaked electrolyte to further protect the batteries. The recess shape and cushioning material are chosen to provide reliable impact absorption and electrolyte containment.

A closure assembly for containers that allows flexible installation methods while providing secure sealing and tamper evidence. The closure has a removable cap and neck insert that can be inserted molded or ultrasonically welded into the container opening. An anchor piece extends from the cap and has an energy-directing protrusion that aligns with a ridge on the neck insert. This allows the cap and insert to be joined by either insert molding or ultrasonic welding. The low profile anchor and base flange facilitate automated or manual assembly. The anchor provides a tamper indication feature when broken during cap removal.

Pouch-shaped lithium battery cell design that improves sealing and prevents electrolyte leakage when a flexible printed circuit board (FPCB) is used inside the cell. The FPCB has a plating layer on the outer surface that contacts the sealed portion of the pouch. A thermal bonding film is added between the plating and the pouch material to increase adhesion and prevent leakage. This prevents electrolyte escape through the seal when the flexible board extends through it.
