Redi pak pressure press and method

Claim 1

A pressure press for the assembly and sealing without the application of heat of apparatus for dispensing individual doses of medication and the like comprising: a. an extended sheet having formed therein spaced pockets into which unit does are placed; b. a stationary base plate on which said sheet is placed and having perforations to accomodate said pockets; c. a cavity card placed on said sheet for enclosing said pockets, said card having perforated closures aligned with said pockets to permit access to each of said pockets, said card being coated with pressure sensitive adhesive on the side making contact with said sheet only in areas other than those above said pockets; d. a cover plate pivotally mounted on said base plate for coming into contact with said cavity card thereby sandwiching said card and sheet between said cover plate and base plate; e. actuator means to cause said cover plate to apply sufficient pressure for a sufficient length of time to cause said cavity card to adhere to said extended sheet thereby sealing each of said doses in a pocket; said actuator means comprising a pressure bar assembly independently pivoted on said base plate to come into contact with said cover plate to exert sufficient force to cause the adhesive to be effective; and f. said cover plate being provided with a block having a camming surface to receive contact from said pressure bar assembly to transmit said force to said cover plate and means to prevent excessive force from being applied.

Claim 3

The method of sealing a cavity card to a sheet having pockets into which unit dosages of medication are placed comprising the steps of placing said sheet on a base plate having openings completely therethrough to accomodate said pockets permitting the the latter to pass completely through said plate, placing said card on said sheet and having a coating of pressure sensitive adhesive only in areas to make contact with said sheet, pivoting a cover plate hinged on said base plate to form a sandwich of said card and sheet between the cover and base plates said cover plate having a camming block, and pivoting independently of said cover plate on said base plate an arm assembly to make contact with said cover plate on said camming block to bring sufficient force on said sandwich to effect sealing of said card to said sheet.

Claim 4

The method of sealing a cavity card to a sheet having pockets into which unit dosages of medication are placed comprising the steps of placing said sheet on a base plate having openings completely therethrough to accomodate said pockets permitting the the latter to pass completely through said plate, placing said card on said sheet and having a coating of pressure sensitive adhesive only in areas to make contact with said sheet, pivoting a cover plate hinged on said base plate to form a sandwich of said card and sheet between the cover and base plates said cover plate having a camming block, and pivoting independently of said cover plate on said base plate an arm assembly to make contact with said cover plate on said camming block to bring sufficient force on said sandwich to effect sealing of said card to said sheet.
