Claim 5

A liquidizer jar in accordance with claim 3 wherein the lower ends of said deflectors are above the level of said cutting zone to provide a circular cutting zone above the lower opening of the jar around the cutters journaled in the jar.

Claim 6

The combination called for in claim 3 in which said deflectors are of uniform cross section shape throughout their length and terminally join said access opening flange to direct inwardly and downwardly contents reaching that level.

Claim 7

Claim 8

A liquidizer jar comprising: an upwardly tapering wall having a top access opening and a bottom opening, said access opening being too small to receive human hands therethrough of a size most users have and said bottom opening having an area large enough to receive hands of most users; a radially inturned flange in said access opening having an internally tapering mouth with a circumferential rib and a radially extending pouring lip, said flange and lip being substantially located at the same level; closure means having a depending flange terminally enlarged diametrically to a size interfering with said rib to engage said circumferential rib in snap sealing relationship; a base member including a bottom wall and an upstanding flange encompassing the rim of said bottom opening in rotatably sealed relationship; a cutter assembly including a shaft rotatably journaled in said bottom wall and connectable to a drive motor; and vertically extending deflector convolutions in said wall having lower termini above the level of said cutter and upper termini at said radially inturned flange and cooperating with said tapered wall to inwardly direct to the center of said jar contents of the jar swirling upwardly from said cutter along said wall.

Claim 9

A liquidizer jar comprising: an upwardly tapering wall having a top access opening and a bottom opening, said access opening being too small to receive human hands therethrough of a size most users have and said bottom opening having an area large enough to receive hands of most users; a radially inturned flange in said access opening having an internally tapering mouth with a circumferential rib and a radially extending pouring lip, said flange and lip being substantially located at the same level; closure means having a depending flange terminally enlarged diametrically to a size interfering with said rib to engage said circumferential rib in snap sealing relationship; a base member including a bottom wall and an upstanding flange encompassing the rim of said bottom opening in rotatably sealed relationship; a cutter assembly including a shaft rotatably journaled in said bottom wall and connectable to a drive motor; and vertically extending deflector convolutions in said wall having lower termini above the level of said cutter and upper termini at said radially inturned flange and cooperating with said tapered wall to inwardly direct to the center of said jar contents of the jar swirling upwardly from said cutter along said wall.

Claim 10

In a liquidizer, a liquidizing container comprising: a jar member having an upwardly tapering wall open at both ends; vertically disposed radially projecting deflectors extending to the upper end of said wall; a radially tapering annular flange at the top of said wall and deflectors defining an access opening of substantially reduced size; a base member releasably closing the bottom opening in sealed relationship; a cutter assembly including cutters mounted on a shaft journaled in the base and defining a cutting zone in the bottom of said wall below the lower ends of said deflectors; and a closure means for said access opening releasably supported on said flange and having a portion received in said access opening in snap engagement with said flange; said access opening being smaller than the average size hands of users to obstruct insertion of a hand; said bottom opening having a size larger enough to receive the hand of most users for cleaning purposes.

Claim 11

In a liquidizer, a liquidizing container comprising: a jar member having an upwardly tapering wall open at both ends; vertically disposed radially projecting deflectors extending to the upper end of said wall; a radially tapering annular flange at the top of said wall and deflectors defining an access opening of substantially reduced size; a base member releasably closing the bottom opening in sealed relationship; a cutter assembly including cutters mounted on a shaft journaled in the base and defining a cutting zone in the bottom of said wall below the lower ends of said deflectors; and a closure means for said access opening releasably supported on said flange and having a portion received in said access opening in snap engagement with said flange; said access opening being smaller than the average size hands of users to obstruct insertion of a hand; said bottom opening having a size larger enough to receive the hand of most users for cleaning purposes.

Claim 12

The combination called for in claim 8 in which the inside radial depth of the flange is appreciably greater than the radial height of said deflector on the inside wall of the jar member.

Claim 13

A liquidizer jar in accordance with claim 8 in which said flange has a circumferential rib defining said access opening and said closure means has a resilient depending flange in interference engagement with said circumferential rib in a snap sealing relationship.

Claim 14

The combination called for in claim 8 in which said wall at the deflectors are externally depressed to provide finger grip recesses for handling said container with a radially extending flange bordering the tops of said recesses.

Claim 15

A combination with a liquidizer container having a flange whose inner edge defines an access opening; a closure made of a resilient material having an upstanding handgrip wall engaging the top of the flange with an edge normally defining a circle which when gripped radially operates to axially distort the edge of the wall from a circle; a resilient axial flange having an external circular ridge element of a size larger than said opening received in said opening in snap engagement when said wall edge engages the flange; said axial flange being axially supported by said grip wall and being distorted in limited areas when said grip wall is pressure distorted to lift the axial flange axially and progressively release said snap engagement.

Claim 16

A combination with a liquidizer container having a flange whose inner edge defines an access opening; a closure made of a resilient material having an upstanding handgrip wall engaging the top of the flange with an edge normally defining a circle which when gripped radially operates to axially distort the edge of the wall from a circle; a resilient axial flange having an external circular ridge element of a size larger than said opening received in said opening in snap engagement when said wall edge engages the flange; said axial flange being axially supported by said grip wall and being distorted in limited areas when said grip wall is pressure distorted to lift the axial flange axially and progressively release said snap engagement.

Claim 17

A liquidizer jar in accordance with claim 12 wherein: said closure is provided with a predetermined number of diametrically disposed intersecting struts across the circle defined by said handgrip wall; and with partial radial intermediate struts disposed between said handgrip wall and said axial flange staggered with respect to said intersecting struts; said axial flange being distorted by pressure applied through said intermediate struts when said grip wall is distorted between said intersecting struts.
