Abstract

A two-piece combination pouring trough and splash shield for use with a food mixer bowl. The two pieces may be selectively locked together or separated as desired. When locked together, the two pieces form a frusto-conical splash shield. Integrally formed with the splash shield is a pouring trough. A pair of concentric annular ribs are secured to the frusto-conical splash shield whereby the assembled splash shield may rest on the top edge of a bowl and may accommodate various sizes of mixing bowls. The locking mechanism for locking the two pieces of the splash shield together may be configured as a ball and socket arrangement or a tab and slot arrangement.

Claims

1. A detachable combination pouring trough and splash shield for use with a mixing bowl, comprising:

a generally planar ring having first and second faces, said ring having an upstanding splash flange mounted on said first face, said ring and splash flange being formed of a plurality of separable portions which are adapted to be assembled and interlocked, said plurality of separable portions comprising a first separable portion having two first ends, and a second separable portion having two second ends, each first end including a projection with a protrusion near an outward edge of said projection, each second end including a socket adapted to receive a said protrusion, one of said separable portions being pivotable on a second said separable portion to release said protrusions from said sockets for separating said separable portions, each said first end including an out-turned flange which forms a shoulder with said associated splash flange, each said second end being configured to permit pivoting movement of said first separable portion through a predetermined arc without engagement of said second ends of said second separable portion with said shoulders; and

a pouring trough secured to one of said separable portions, whereby said combination pouring trough and splash shield may be placed on a mixing bowl while said mixing bowl is mounted on a mixer.

2. The device as set forth in claim 1 including a pair of concentric annular ribs mounted on the second face of said ring.

3. The device according to claim 1 wherein said splash flange is substantially frusto-conical.

4. The device according to claim 1 wherein said ring and splash flange are split substantially along a central plane thereof to form said separable portions.

5. A detachable combination pouring through and splash shield for use with a mixing bowl, comprising:

a generally planar ring having a first face and a second face, said ring having an upstanding generally frusto-conical splash flange mounted on said first face and two concentric generally cylindrical ribs mounted on said second face, said ribs separated by a groove, said ring, splash flange, and ribs being formed of two separable portions which are adapted to be assembled and to interlock in their assembled positions, a first separable portion including two first ends comprising projections with a protrusion near an outward edge of each said projection and a second separable portion including two second ends comprising sockets for receiving said respective protrusions, one of said portions being pivoted for releasing said respective protrusions from said respective sockets for separating said two separable portions, each first end including an out-turned flange which forms a shoulder with said one splash flange portion, each second end being configured to permit pivoting movement of a second separable portion through a predetermined arc without engaging said shoulders; and

a pouring trough secured to one of said separable portions, whereby said combination pouring trough and splash shield may be placed on a mixing bowl while said mixing bowl is mounted on a mixer.

6. The device according to claim 5 wherein said splash shield is split substantially along a central plane thereof to form said separable portions.

7. A detachable two-piece combination pouring trough and splash shield for use with a food mixer bowl comprising:

a first section having a first and second face, said first section including a first generally planar portion, a first upstanding splash flange portion secured to said first face of said first planar portion, and a pouring trough secured to said first upstanding splash flange portion;

a second section having a first and second face, said second section including a second generally planar portion, and a second upstanding splash flange portion secured to said first face of said second planar portion;

said first section having two first ends which include projections thereon with respective protrusions at the respective outward edges of said projections, and each said second section having two second ends which each include a socket for receiving a said protrusion, one of said sections being adapted to pivot for releasing said respective protrusions from said respective sockets for separating said two sections, each said first end including an out-turned flange which forms a shoulder with said first splash flange portion, each said second end being configured to permit pivoting movement of said second section through a predetermined arc without engagement of said second ends with said shoulders; and

means for removably locking said first section to said second section whereby said first and second splash flange portions form a unitary splash flange and which is separable into said first and second splash flange portions substantially along a central dividing plane, whereby said combination pouring through and splash shield may be placed on a mixing bowl while said mixing bowl is mounted on a mixer.

8. The device according to claim 7 wherein each said first and second section includes a pair of ribs mounted on said second face of each said first and second generally planar portions, said ribs arranged in concentric circles when said first section is locked to said second section.

9. The device according to claim 7 wherein said splash flange portions in the locked position of said section form a substantially frusto-conical flange.

10. A combination pouring trough and splash shield for use with a mixing bowl, comprising:

a generally planar ring with a first and second face, said ring having an upstanding splash flange mounted on said first face, said ring and splash flange being formed of a first and a second separable portion which are adapted to be assembled and interlocked, said first separable portion having two first ends and said second separable portion having two second ends; and

a pouring trough secured to one of said separable portions;

each said first end including a projection with a protrusion at the end thereof and an out-turned flange which forms a shoulder with an associated splash flange;

each said second end including a socket adapted to receive a said protrusion and being configured to permit pivoting movement of said first separable portion through a predetermined arc without engagement of said second ends of said second separable portion with said shoulders;

said first separable portion pivotable on said second separable portion to release said protrusions from said sockets for separating said separable portions whereby said combination pouring trough and splash shield may be placed on a mixing bowl while said mixing bowl is mounted on a mixer.

11. A detachable combination pouring trough and splash shield for use with a mixing bowl, comprising:

a generally planar ring having first and second faces, said ring having an upstanding splash flange mounted on said first face, said ring and splash flange being formed of a plurality of separable portions which are adapted to be assembled and interlocked, said plurality of separable portions comprising a first separable portion having two first ends, and a second separable portion having two second ends, each first end including an upstanding tab on said ring, each second end including a slot on said ring adapted to receive a said tab, one of said separable portions being removable from a second separable portion to release said tabs from said slots for separating said separable portions,

a pouring trough secured to one of said separable portions, whereby said combination pouring trough and splash shield may be placed on a mixing bowl while said mixing bowl is mounted on a mixer.

12. The device according to claim 11 wherein each said tabs includes ribs for gripping an edge of a said respective slots.
