In a method of filling a packaging container, a liquid is charged in a container through an opening in a top end of the container to a first level below the top end of the container. The container has a deformable portion in a wall thereof so that an inside volume of the container can be adjusted. A lid is sealed on the opening, and the deformable portion of the container is deformed to elevate the liquid above the first level.

A pull-tab for a liquid container according to the present invention is designed in form of a sheet, and by providing a cutting line in form of a ring, leaving a connecting sector on the periphery, it comprises a handle sector, being the portion outside said cutting line, and a main sector, being the portion inside the cutting line. By providing another cutting line in convex arc in the direction away from the connecting sector on the main sector, a fastening sector is formed. In this pull-tab, the main sector covers the pouring mouth when the connecting sector is positioned near outer periphery of the pouring mouth of the liquid container. A sector between an end of the main sector opposite to the connecting sector and a fastening sector is bonded to the surface of the liquid container. When the handle sector is lifted up and the main sector is pulled up with edges of the bonded sector as a supporting axis, the fastening sector is turned, and its forward end is stopped on the surface of the liquid container.

A crosslinked polyurethane polyurea spherically particulate polymer having an average particle diameter of 0.1 to 500 .mu.m, wherein the polymer molecule contains an isocyanurate ring in an amount of 10 to 30% by weight is disclosed. A process for producing the crosslinked polyurethane polyurea spherically particulate polymer is also disclosed. The process comprises the steps of: reacting an isocyanurate ring-containing polyisocyanate compound with a polyhydroxy compound to form an organic phase capable of forming a three-dimensional crosslinked structure due to the reaction, wherein the amount of isocyanate groups in the polyisocyanate compound is stoichiometrically larger than that of hydroxyl groups in the polyhydroxy compound; finely dispersing the organic phase into water; and adding a polyamine to the dispersion to make interfacial polymerization between the organic phase and the polyamine and a polyurethane-forming reaction within particles, wherein the amount of the polyamine is stoichiometrically equivalent to or smaller than the stoichiometrical excess of isocyanate groups. The particulate polymer is excellent in solvent resistance and has a completely spherical shape without wrinkle on the particle surface. The particulate polymer has a good toughness and mechanical properties. Further, the particulate polymer has no reactive isocyanate group in the polymer molecule.

An object is to enable a strip tape to be bonded to a packaging material at a proper position and enable longitudinal sealing to be performed well. A packaging-container manufacturing apparatus includes a bonding member, a first detection section which detects an edge of the packaging material, a second detection section which detects an edge of the strip tape (12), position determination processing means for determining the position of the strip tape (12) in relation to the packaging material, and position correction processing means for correcting the position of the strip tape (12) in relation to the packaging material. Since the position of the strip tape (12) in relation to the packaging material is determined on the basis of outputs of the first and second detection sections and the position of the strip tape (12) in relation to the packaging material is corrected on the basis of results of the determination on the position, the strip tape (12) is placed on the packaging material at a proper position.

A packaging filling apparatus, which can obtain the most suitable sealing quality by an automatic control without checking the condition of the sealing by the operator on a regular basis, is provided. A transversal sealing apparatus 48 of the packaging filling apparatus includes a high-frequency oscillator 1, controller 2, and an inductor, which generates a magnet field in packaging material by receiving the output from the high-frequency oscillator, and is provided with a sealing quality control means 4, which transmits a control signal to the controller, based on a statistical relation between a plurality of effect factors affecting the quality of a transversal sealing 23 and the quality of transversal sealing.
摘要:
A packaging and filling apparatus fills a tube of a web of a packaging material with a fluid product, forms lateral seal bands, cuts each seal band of a series of pillow-like preformed bodies with a cutting device to form a packaging and filling container of the final form. The cutting device comprises a resistance measuring device for measuring a cutting resistance pressure that a packaging material cutting blade receives from the packaging material, and then outputting a measurement value obtained, and a blade monitoring device for monitoring the condition of the packaging material cutting blade based upon based upon a comparison of a difference between a maximum measured cutting resistance pressure and a constant measured cutting resistance pressure following the maximum measured cutting resistance pressure with a predetermined pressure difference reference value.

A packaging and filling apparatus and a packaging material cutting device are provided, in which the knife of the cutting device can be replaced with appropriate timing by quantitatively determining the service life of the knife of the cutting device. The packaging and filling apparatus fills a tube of a web of a packaging material with a fluid product, forms lateral seal bands by sealing the tube in the direction in which the bands intersect the tube, cuts each seal band of a series of pillow-like preformed bodies with a cutting device such that the pillow-like preformed bodies are severed from each other, thus forming a packaging and filling container of the final form. The cutting device 32 comprises: a resistance measuring means for measuring the cutting resistance that a packaging material cutting blade 33 receives from the packaging material, and then outputting a measurement value obtained; and a blade monitoring means for monitoring the condition of the packaging material cutting blade based upon the measurement value.
摘要:
When using web-shaped packaging material in which the rear end of a packaging material is spliced to the front end of a next web-shaped packaging material, in order to continuously operate the filling machine for paper container, notches are provided on a corner portion of the paper spliced portion around the metal layer. Even if a paper spliced portion is included in the web-shaped packaging material, in the filling machine seal insufficiency is not generated in the longitudinal seal of the paper spliced portions, and an interruption due to the broken part of continuous operation is prevented.

The object is to provide a lid (11) that does not cause environmental pollution. The lid (11) comprises a lid body (12) formed of a plastic sheet and a pull-cap (14) formed of a plastic sheet. The lid body (12) covers a top end opening of a cylindrical container body (15) and has an opening-for-drinking (16). The pull-cap (14) has a sealing portion (20) for covering the opening-for-drinking (16) of the lid body (12) and for sealing the periphery of the opening-for-drinking (16), and a pull-tab portion (21) formed integrally with the sealing portion (20). The sealing portion (20) has an easy-to-peel layer. A holding groove portion is formed in the lid body (12) at a location different from the location of the opening-for-drinking (16), and a pull-cap holding section for holding the pull-cap (14) peeled off is formed at the holding groove portion. Since the pull-cap (14) can be held by the pull-cap holing section after it is peeled off, the pull-cap (14) is not likely to be thrown away carelessly after the pull-cap (14) is peeled off the lid body (12) to open the beverage container.
