Abstract
Abstract A package with spreader is hermetically sealed for storing relatively stiff spreadable materials such as butter until ready for use. The package includes a base having a relatively stiff spreader blade partially defined by a blade spread side surface and an opposed base supply side. The base also includes a deformable blister for holding the spreadable material. The blister is open through the blade to its spread side surface and extends outwardly from the blade on the supply side of the base. A peelable membrane initially seals the butter inside of the blister by being in sealing relation to the spread side surface of the blade. A portion of the membrane is manually peelable from sealing relation with respect to part of the blade and uncovers a portion of the blister to provide a butter delivery opening through which the butter can be forced by digital pressure on the outside of the blister. The butter can then be immediately spread using the sealing side surface of the blade.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
206 words
A package and spreader unit for spreadable material including: A. a base of sheet material having: (1) an elongate, relatively stiff, planar blade partially defined by a blade spread side surface and an opposed spaced-apart supply side of the base, said blade having a forward delivery end portion and a rearward handle end portion, and (2) a deformable blister adapted to initially encompass spreadable material, said blister being part of the supply side of the base and being open through said blade and extending outwardly from it on the supply side of the base; B. a planar membrane initially overlying the opening of the blister through the blade in sealing relation to the spread side surface of the blade around the blister to form a closed receptacle for the spreadable material, a first portion of said membrane adjacent the blade delivery end portion and in underlying relation to a portion of said blister immediately adjacent said blade delivery end portion being manually peelable from sealing relation with respect to said blade, and being frangible and removable from said blade and separable from a second remaining sealed portion of the membrane to provide an outlet for the spreadable material to the spread side surface of the blade.
Claim 2
Dependent Claim
206 words
A package and spreader unit for spreadable material including: A. a base of sheet material having: (1) an elongate, relatively stiff, planar blade partially defined by a blade spread side surface and an opposed spaced-apart supply side of the base, said blade having a forward delivery end portion and a rearward handle end portion, and (2) a deformable blister adapted to initially encompass spreadable material, said blister being part of the supply side of the base and being open through said blade and extending outwardly from it on the supply side of the base; B. a planar membrane initially overlying the opening of the blister through the blade in sealing relation to the spread side surface of the blade around the blister to form a closed receptacle for the spreadable material, a first portion of said membrane adjacent the blade delivery end portion and in underlying relation to a portion of said blister immediately adjacent said blade delivery end portion being manually peelable from sealing relation with respect to said blade, and being frangible and removable from said blade and separable from a second remaining sealed portion of the membrane to provide an outlet for the spreadable material to the spread side surface of the blade.
Claim 3
Dependent Claim
39 words
The package and spreader unit of claim 1, and: C. means for predetermining the size and shape of the first peelable portion of the membrane which can be manually removed from the second remaining sealed portion of the membrane.
Claim 4
Dependent Claim
44 words
The package and spreader unit of claim 1 wherein: C. a third portion of the membrane is integral with the first portion and is not initially in sealed relation with respect to the blade to facilitate removal of the first portion of the membrane.
Claim 5
Dependent Claim
26 words
The package and spreader unit of claim 3 wherein: D. the third portion of the membrane is initially in overhanging relation with respect to the blade.
Claim 6
Dependent Claim
51 words
The package and spreader unit of claim 4 wherein: E. the third portion of the membrane extends forwardly of the delivery end portion of the blade; and F. a finger grip is provided forwardly of the blade, said finger grip being in fixed relation to the thrid portion of the membrane.
Claim 7
Dependent Claim
48 words
The package and spreader unit of claim 5 wherein: G. said finger grip extends forwardly of the blade and is manually movable away from the blade by movement of it and the third portion of the membrane in direction away from the supply side surface of the blade.
Claim 8
Dependent Claim
38 words
The package and spreader unit of claim 1 wherein: C. the base is made of a polystyrene sheet; and D. the membrane includes an aluminum foil laminate covered on one side surface with a poly based thermoplastic adhesive.
Claim 9
Dependent Claim
38 words
The package and spreader unit of claim 6 wherein: H. the base is made of a polystyrene sheet; and I. the membrane includes an aluminum foil laminate covered on one side surface with a poly based thermoplastic adhesive.
Claim 10
Dependent Claim
