Abstract
By means of the method proposed the joining of a cap and a body of a capsule used to enclose medicines, with the open end of the body already inserted in the cap, is achieved by directing a flow of hot compressed fluid, progressively on a circular portion of the cap overlapping a relative underlying circular portion of the body, so as to affect the entire circumference of the circular portion of the cap; the resulting seal between the said portions prevents separation, without breaking, of the cap or the body.
Claims21
A method using a flow of fluid for joining a cap and body of a capsule used to enclose medicines, said body having and end fitted inside an open end of said cap, a portion of said cap overlapping a correspondingly shaped portion of said body, comprising the steps:
- (a) directing a flow of heated fluid from a source to impinge said overlapped portions on said capsule;
- (b) moving said capsule and flow relative to each other causing said flow to heat a peripheral overlapped strip on said cap;
- (c) adjusting the rate, pressure and temperature of said flow source to transmit heat at a desired rate from said fluid flow into said cap in said strip, and from said cap to said overlapped portion of said body in said strip, whereby said body and cap overlapped portions soften and seal together.
An apparatus using a flow of fluid for joining a cap and body of a capsule used to enclose medicines, said body having an end fitted inside and open end of said cap, a portion of said cap overlapping a correspondingly shaped portion of said body, comprising:
- a source outputting a high velocity fluid flow;
- means for positioning said capsule with said overlapped portions intercepting said fluid flow;
- means for heating said fluid flow prior to contact of said fluid with said capsule, said heated flow softening said overlapped layers and producing sealing thereat.
