Tamper Evidence in Package Protection

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.

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.

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.

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.

Eco-friendly packaging with a removable tamper-evident seal that improves recyclability and provides tamper indication. The seal is made of paper and attaches to the box and lid. It has a tearable tab that breaks when pulled, separating the seal from the box and lid. This allows opening the package but leaves the seal intact to show if it was previously opened. The seal can be easily recycled separately from the box and lid. The packaging uses recyclable materials and aims to reduce environmental impact compared to plastic-based packaging.

Pouch design and filling method to detect and prevent displacement of film perforations when the pouch is filled. The pouch has inner film with perforations overlapped on the outer film at the sealing points. This allows external visual confirmation of perforation positions. When filling, a spout is used to access the lower chamber and move contents into the upper chamber through the overlapped perforations. This allows gas escape and prevents displacement of the perforations during filling.

Packaging container with a simple design to deter and prevent tampering. The container has a lid that seals over a container body. The lid flange fits into the container flange. The container flange has a standing wall section on the outside flange and a connecting section between the flanges. A cleavage section is provided along the connecting section to easily break it. This allows checking if the lid has been opened. If the cleavage section is broken, it indicates the lid was opened. This deters tampering as consumers can see if a container has been opened. The vertical wall section prevents accidental lid opening during transport.

Resealable lid for a packaging container with improved tamper-evident features. The lid has a main body that covers the container opening and an adjacent portion. A cutout area with multiple cut pieces is formed at the boundary between the main body and adjacent portion. The main body is made of two substrates with adhesive layers. The cutout region doesn't have adhesive on the back of the inner substrate, or a weaker adhesive layer. This prevents easy resealing of the cutout area. When the lid is reopened, the cut pieces break in a distinctive pattern visible as an indication of tampering.

Packaging with tamper-evident features that allow easy opening but also provide clear indications of tampering. The packaging has a base and a lid that rotates open around a hinge axis. Before first opening, a main tab on the lid is connected via a weak line to a tamper evidence tab on the base. If the main tab is folded before rotating the lid, it separates along the weak line. This reveals tampering if the tab is not properly folded.

Protective packaging for suitcases that provides protection against tampering while being fully recyclable and avoids using excessive plastic like traditional packing methods. The packaging is a foldable cardboard box shaped like a prism with an elongated rectangular base, matching the suitcase size. The side walls and closing flange fold up and glue together to form a tubular shape. The bottom and upper base are separate pieces that attach to complete the box. This allows the suitcase with wheels and handle to be used normally inside the cardboard packaging. The cardboard walls protect against knocks and scratches, and any tampering is evident from the folded cardboard flaps.

A sustainable double closure paper pouch for packaging items in a robust and commercially practical way with parallel reinforcable sticky strips for back-to-back sealing of the mouth to provide tamper evidence, spillage prevention, and robustness while being environmentally responsible. The pouch has parallel sticky strips running along the top of the front and back walls that are covered by tearable paper tabs. Severing the tabs allows the strips to adhere together to seal the pouch back-to-back. This creates a thick single wall without folds for sealing and closure. The reinforced strips provide secure sealing and spillage prevention, the tearable tabs enable easy opening, and the back-to-back sealing provides tamper evidence. The pouch can be made from eco-friendly materials like uncoated recyclable paper.

A packaging container with a removable cover that provides improved child resistance and tamper evidence. The container has a base, a sidewall extending upwardly from the base, and a cover that is removably connected to the sidewall. The cover has a first portion that extends over the top of the sidewall and a second portion that overlaps the first portion and is adjacent to the top of the sidewall. The second portion has a plurality of child-resistant locking tabs that engage with corresponding locking features on the sidewall to secure the cover in place. The container also includes a child-resistant sealing member that is located between the cover and the sidewall and seals the container when the cover is connected. This provides both child resistance and tamper evidence.

Inspecting packages made by shrink-wrapping or stretch-wrapping objects using a technique that allows detecting tears in the packaging material without using special ultraviolet-absorbing packaging materials. The technique involves using a camera to image the package after irradiating it with ultraviolet light. The camera captures specular reflection images that reveal tears as dark areas. By analyzing the images, the quality of the packaging material can be determined without needing specialized materials. This improves inspection accuracy compared to fluorescent images.

Standing pouch with a unique seal configuration to prevent pinholes and leaks when the pouch is upright. The seal has a corner cutout, inclined seal, top seal, first side seal, and second side seal. The top seal connects to the inclined seal and is wider than the second side seal. This prevents bending at the narrower top when the pouch is lying on its side during manufacturing and transportation. The wider top seal distributes the force instead of concentrating it at the narrower side seal. This reduces pinholes and leaks when the pouch is upright due to rubbing against containers.

Preventing counterfeiting of high-value bottled products like wine, drugs, and luxury foods by using ambient electromagnetic power harvesting (AEPH) chips that extract power from RF fields. The chips are affixed to containers and closures. One chip is read-only and broken when opened. The other chip stores transport info. Authentication codes are checked at transfer points. If codes don't match, it indicates tampering. This enables tracking provenance and authenticity of bottled products using electronic scanning systems.

A metal can with a resealable lid that has a unique shape for the curled portion on the opening. The curled portion has an upper end rounded portion with a smaller radius than the lower end rounded portion. This prevents the lower rounded portion from spreading outward when force is applied, preserving the can's tamper-evident seal. The upper rounded portion has a shorter radial length than the lower rounded portion. The escape surface below the curled portion has a larger radius than the lower rounded corner. This prevents the lower rounded portion from contacting and deforming the escape surface. The shape prevents the curled portion from expanding outward when force is applied, maintaining the seal and tamper-evident properties.
