An easy separable sealed portion is continuously formed in the side edge part of the packaging film by the first vertical sealed portion forming section, and a vertical sealed portion having a partial non-sealed portion of a bottle mouth type is formed on the easy separable sealed portion by the second vertical sealed portion forming section. The first vertical sealed portion forming section is a pair of heat sealing rolls or heat sealing plates, a surface of at least one of which is made from an elastic material softer than a metal.

Apparatus and method for making inflated articles

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

Bonding device and method for producing plate-shaped bonded assembly

A bonding device for charging a liquid material into a space between plate-shaped members for bonding them together in situ, in which the liquid material may be prevented from exuding from the space between the plate-shaped members. The bonding device includes pair retaining base members for retaining the pair plate-shaped members facing each other, and a retaining base member movement unit for causing movement of the retaining base members towards and away from each other. The bonding device also includes an illumination unit that illuminates curing light to a photo-curable liquid material charged between the pair plate-shaped members held by the pair retaining base members, and a sensor that detects the wetting spreading state of the liquid material charged between the pair plate-shaped members.

20220040951 · 2022-02-10 ·

Disclosed are embodiments of a volume control storage bag and methods of making same. The volume control storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A gusset is sealed along three sides of the first and second sidewalls, leaving an opening through the closure mechanism and defining an interior space having a specific volume. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The volume control storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

METHOD FOR THE PRODUCTION AND FILLING OF AN APPLICATION PACKAGE FOR A LIQUID PHARMACEUTICAL PRODUCT

A method for the production and filling of an application package for a liquid pharmaceutical product. A thermoforming film made of thermoplastics laminated together is heated in order to plasticize the thermoforming film at least in partial areas. The plasticized areas are thermoformed in a mold in order to form a chamber for the liquid pharmaceutical product and a tube-shaped application duct opening into this chamber, with the chamber and the application duct being enclosed by a non-thermoformed, essentially flat bonding area of the thermoforming film. The liquid pharmaceutical product is filled into the chamber, and the chamber and the application duct are sealed by covering the thermoformed and filled thermoforming film with an essentially flat covering film. The covering film is directly bonded to the bonding area of the thermoforming film by thermal ring sealing, enclosing the chamber and the application duct.

Method for assembling a box structure and structure obtained by such a method
09731487 · 2017-08-15 · ·

A method for assembling a skin and a flange of a stiffener. The periphery of the contact between the skin and the flange of the stiffener is sealed by applying a bead of adhesive on the flange of the stiffener in contact with the skin. A first and second orifices are made in the skin. The orifices open at the interface between the skin and the flange of the stiffener. The adhesive is injected through the first orifice at the interface between the skin and the flange of the stiffener while keeping the skin in contact with the stiffener until the interface between the skin and the stiffener is completely filled with the adhesive.

SYSTEMS AND METHODS USING MULTIPLE SYNCHRONIZED ULTRASONIC TRANSDUCERS TO FINISH A PART

An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.

Systems and methods using an ultrasonic transducer and scrubbing horn motion to seal a part

An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.
