Abstract: A bottle-shaped can in which a cap can be mounted on a neck portion without damaging slits and bridges. An annular bead comprises a diametrically largest portion, an upper inclined surface, and a lower inclined surface. An angle of inclination of the upper inclined surface is narrower than that of the lower inclined surface. A thread ridge comprises an incomplete thread portion in which a groove depth is shallower than an average groove depth of the thread ridge, and the incomplete thread portion is formed at one end of the thread ridge on the upper inclined surface at least partially. An angle of inclination of a lower wall of the thread ridge w is greater than that of the upper inclined surface so that a protruding corner is formed. The slits and the bridges are situated at a level lower than the protruding corner.

Abstract: A bottle-shaped can in which flatness and circularity of a neck portion are improved. An upper incomplete thread portion is formed at an upper end of a thread. A height of the upper incomplete thread portion is shorter than an average height of the thread, and increases gradually toward the average height. A length of the upper incomplete thread portion between a first point and a second point is set in such a manner that an angle between a line drawn between the first point and a center point of the neck portion, and a line drawn between the second point and the center point of the neck portion falls within a range from 20 degrees to 60 degrees.

Abstract: An apparatus and a method for accurately processing a neck portion of a bottle-shaped can without changing a posture of the can. An inner tool is inserted into the neck portion from the bottom of a can body to form a stepped portion, and comprises a first forming section having a diameter smaller than an inner diameter of a neck portion. An outer tool comprises a second forming section that is opposed to the inner tool. The stepped portion is formed on the neck portion by sandwiching the neck portion by the first forming section and the second forming section. The inner tool further comprises a holding member that is situated coaxially with the can body to be contacted to an inner surface of the can body. The holding member is attached to the inner tool while being allowed to move in a radial direction together with the can body.

Abstract: A method of manufacturing a two-piece food can having improved corrosion resistance is provided, wherein the two-piece food can using a metal sheet coated with a thermoplastic resin and having annular uneven beads and/or a bottom rim. After forming a bottomed cylindrical can body by drawing and ironing, by heating at a temperature higher than the melting temperature of the thermoplastic resin for a predetermined time before forming uneven beads and/or a bottom rim to the can body and quenching within a predetermined time after heating, the inner resin coating hardly peel off during the following formation of uneven beads and/or the bottom rim. As a result, a two-piece food can having excellent corrosion resistance may be obtained.

Abstract: A height adjustment apparatus that can reduce a load to trim a can body is provided. The height adjustment apparatus 1 is adapted to adjust a height of a can body to a desired height by trimming one of opening ends of the can body. The height adjustment apparatus comprises: mandrels on which the can body is individually mounted and which revolve along a predetermined orbit while rotating; outer blades arranged around the revolution orbit of the mandrels; an inner blade fitted onto each mandrel to trim the opening end of the can body together with the outer blade; and a vertical reciprocator that gradually changes a level of the opening end of the can body with respect to a level at which the outer blade and the inner blade are situated from an upstream side toward a downstream side in a revolution direction of the mandrel.

Abstract: An induction heating apparatus heats content efficiently while measuring a temperature of the heated content accurately. The induction heating apparatus includes a can holder, a heating coil disposed around the can holder, and a temperature measuring unit. A resealable metal beverage can having a thread formed on a neck portion and a cap screwed onto the neck portion is held by the can holder. The can holder holds the metal beverage can in a manner such that the cap of the can inserted thereto is exposed on an axially upper side. The temperature measuring unit measures a surface temperature of the cap of the metal beverage can held in the can holder.

Abstract: An internal pressure inspection apparatus for a sealed container having a can lid that is attached to any of an upper end and a lower end of a can trunk, and that is deformed by an internal pressure of the container. A laser sensor adapted to measure a distance from the can lid by irradiating the can lid is situated parallel to the can lid while being allowed to move relative to the can lid. The inspection apparatus integrates relative displacement values between a reference point closer to a center of the can lid than a seamed portion and other points closer to a center of the can lid than the reference point, and acceptability of the internal pressure is judged based on the value of integration.

Abstract: The object of the present invention is to improve a pump-dispensing container structured to prevent leakage of liquid caused by slight vertical movements of the nozzle head, to make it easier to push out the liquid when the nozzle head is pressed down first from its highest position. If a primary check valve is configured to open the connection between the inside of the liquid chamber and the inside of the container body in a state in which the liquid chamber is filled with a liquid and the nozzle head is raised to its highest position, when the nozzle head is pressed down from its highest position to push out the liquid, resistance met during the pressing down of the nozzle head is significantly reduced because of the open connection between the inside of the liquid chamber and the inside of the container body, and the liquid can be pushed out easily by applying a small force.

Abstract: It is an object of the present invention to provide a foam dispensing container that can homogenize foam quality and can discharge foam of stable quality. By providing a plurality of liquid intake paths for delivering the foaming liquid into the air-liquid mixing chamber and a plurality of air intake paths for delivering air, the air-liquid mixing efficiency can be improved significantly, stable volumes of air and foaming liquid can be delivered into the air-liquid mixing chamber, without the possibility of delivering a great volume of liquid with a single press, and consequently the foam quality can be homogenized and foam of stable quality can be discharged.

Abstract: A method for inspecting sealing defects of a container using infrared light. Infrared light in a wavelength range of 1450 nm±20 nm is irradiated from a phototransmitter onto the sealed portion of a sample container Infrared light reflected from or transmitted through the sealed portion of the sample container is received by a photoreceiver, and transmitted to a photodetector through an optical fiber. The infrared light in a same wavelength range as the case of inspecting the sample container is irradiated onto the sealed portion of a container to be inspected. The infrared light reflected from or transmitted through the sealed portion of the inspected container is converted into the analog voltage value and transmitted to a controller. If the infrared light is reduced to be smaller than a threshold set on the basis of the sample container, the sealed portion of the inspected container is judged as a sealing defect.
