Definitions
- the present invention relates to a liquid filling nozzle for use in filling a liquid, such as flowable food, into containers.
- filling nozzles are usable free of any problem for free-flowing liquids such as milk but encounter difficulty in handling at a high speed liquids, such as fresh cream and yoghurt, which are low in flowability since such a liquid is not dischargeable from the nozzle quickly and can not be cut sharp, whereas the present applicant has already proposed a nozzle by which even a liquid of low flowability can be filled into containers at a high speed free of trouble like free-flowing liquids.
- the proposed nozzle comprises a tubular nozzle main body, a damper attached to the lower end of the nozzle main body and movable upward and downward, a spring suspending member fixedly provided within the main body at an upper portion thereof, a coiled spring suspended from the suspending member, a member connecting the lower end of the spring to free ends of the damper, and a resistant member secured to the connecting member and positioned below the coiled spring for acting against a downwardly flowing liquid.
- the nozzle When a liquid is forced into the filling nozzle, the liquid pressure acting on the damper opens the damper against the force of the coiled spring, while the liquid pressure on the resistant member also acts to open the damper, opening the damper correspondingly to a greater extent. Consequently, the liquid flows out of the nozzle main body quickly without permitting formation of air bubbles due to agitation of the liquid that would occur at a low flow rate.
- the nozzle is adapted for a high-speed filling operation.
- the main object of the present invention is to provide a filling nozzle for filling a liquid into containers at a higher speed than the foregoing nozzle.
- the liquid filling nozzle of the present invention comprises a vertical tubular nozzle main body, a damper attached to the lower end of the nozzle main body and pivotally movable upward and downward, a resistance member extending within the nozzle main body and being movable upward and downward, a member connecting free ends of the damper to the resistance member, and a resilient member biasing the resistance member upward as known from EP-A-0 138 234.
- the nozzle main body has a reduced diameter portion at an intermediate portion of its height, the arrangement being such that from the rest position where the resistance member is positioned in said reduced diameter portion the resistance member during liquid flow will be shifted in a downward direction to such extent that it leaves said reduced diameter portion.

Description
- The present invention relates to a liquid filling nozzle for use in filling a liquid, such as flowable food, into containers.
- Generally, filling nozzles are usable free of any problem for free-flowing liquids such as milk but encounter difficulty in handling at a high speed liquids, such as fresh cream and yoghurt, which are low in flowability since such a liquid is not dischargeable from the nozzle quickly and can not be cut sharp, whereas the present applicant has already proposed a nozzle by which even a liquid of low flowability can be filled into containers at a high speed free of trouble like free-flowing liquids. As disclosed in Examined Japanese Patent Publication SHO 59-26550, the proposed nozzle comprises a tubular nozzle main body, a damper attached to the lower end of the nozzle main body and movable upward and downward, a spring suspending member fixedly provided within the main body at an upper portion thereof, a coiled spring suspended from the suspending member, a member connecting the lower end of the spring to free ends of the damper, and a resistant member secured to the connecting member and positioned below the coiled spring for acting against a downwardly flowing liquid. When a liquid is forced into the filling nozzle, the liquid pressure acting on the damper opens the damper against the force of the coiled spring, while the liquid pressure on the resistant member also acts to open the damper, opening the damper correspondingly to a greater extent. Consequently, the liquid flows out of the nozzle main body quickly without permitting formation of air bubbles due to agitation of the liquid that would occur at a low flow rate. Thus, the nozzle is adapted for a high-speed filling operation.
- In recent years, however, there is a growing demand for a more efficient filling operation at a higher speed than is attainable by the above filling nozzle, so that it is desired to develop a filling nozzle which is operable at a higher speed than the proposed device.
- The main object of the present invention is to provide a filling nozzle for filling a liquid into containers at a higher speed than the foregoing nozzle.
- The liquid filling nozzle of the present invention comprises a vertical tubular nozzle main body, a damper attached to the lower end of the nozzle main body and pivotally movable upward and downward, a resistance member extending within the nozzle main body and being movable upward and downward, a member connecting free ends of the damper to the resistance member, and a resilient member biasing the resistance member upward as known from EP-A-0 138 234.
- According the present invention, the nozzle main body has a reduced diameter portion at an intermediate portion of its height, the arrangement being such that from the rest position where the resistance member is positioned in said reduced diameter portion the resistance member during liquid flow will be shifted in a downward direction to such extent that it leaves said reduced diameter portion.
- So the liquid flows down said reduced diameter portion at a higher speed than when flowing down the portion above or below this portion, while the resistance member is upwardly and downwardly movably retained in the reduced diameter portion. Consequently, the liquid pressure acting on the resistance member is greater than that acting on the resistance member of the conventional nozzle described above, with the result that the damper can be opened to a correspondingly greater degree. This assures a filling operation at a higher speed.
- Fig. l is a view in vertical section showing an embodiment of the invention;
- Fig. 2 is a perspective view showing the same with a nozzle main body partly broken away; and
- Fig. 3 is a fragmentary view in vertical section showing another embodiment.
