A foam dispensing container includes: a cap mounted on an opening of a container containing a foamable liquid content; a nozzle having an outlet fitted onto the cap while being allowed to reciprocate; an air pump and a liquid pump reciprocated together with the nozzle; an air cylinder joined to the air pump liquid and pushing air toward the outlet in response to reciprocation of the air pump; a liquid cylinder joined to the liquid pump liquid tightly and pushing a liquid toward the outlet in response to reciprocation of the liquid pump; and a refining member arranged in the cap to form the foam by mixing the air pushed out of the air cylinder with the liquid pushed out of the liquid cylinder, and to refine the foam. A density of the foam dispensed from the discharging outlet falls within a range of 0.03 g/cmto 0.06 g/cm.

Foam dispensing container

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.

Forming apparatus and forming method for neck portion of bottle-shaped can

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.

Threaded bottle-shaped can and manufacturing method thereof

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 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.

Bottle-shaped can with cap

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.

Induction heating apparatus for a beverage can

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.
