Abstract
Abstract A generally flat based tray is used for both shipping and display of internal combustion engine oil filters. The typical oil filter has female threads in one end of a cylindrical base and utilizes an annular gasket on that cylindrical base to make a seal with the engine. The generally flat base of the tray includes frusto-conical male projections which are laterally deformable so that the threads of the oil filter are screwed onto these projections and deform them to establish formed threads on the projections which secure the oil filter to the tray and also trap the annular gasket between the oil filter and the tray base. The entire package may be shrink wrapped with a transparent material to aid in securing the filters to the tray especially during the rough handling of shipping. The trays may be utilized as a display device by being laid flat on a horizontal surface or may be hung by keyhole slots to be displayed on a vertical surface. The empty trays may be stacked with the projections interfitting to permit this stacking. The loaded trays may also be stacked, the shrink-wrap material being sufficiently resilient to permit an interfitting engagement between upper and lower packages. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
88 words
A shipping and display tray for use in connection with a plurality of internal combustion engine oil filters having female threads and annular gaskets comprising, in combination, a generally flat base, a plurality of male projections protruding upwardly from and attached to said base, said projections being of a semi-rigid material deformable in a direction parallel to said base, and said projections being engageable by female threads on an oil filter to trap the annular gasket of the oil filter between said flat base and the oil filter.
Claim 2
Dependent Claim
88 words
A shipping and display tray for use in connection with a plurality of internal combustion engine oil filters having female threads and annular gaskets comprising, in combination, a generally flat base, a plurality of male projections protruding upwardly from and attached to said base, said projections being of a semi-rigid material deformable in a direction parallel to said base, and said projections being engageable by female threads on an oil filter to trap the annular gasket of the oil filter between said flat base and the oil filter.
Claim 3
Dependent Claim
22 words
A tray as set forth in claim 1, wherein said projections are laterally deformably threadable by female threads on an oil filter.
Claim 4
Dependent Claim
24 words
A tray as set forth in claim 1, wherein said projections are unitary with said flat base and are formed of the same material.
Claim 5
Dependent Claim
28 words
A tray as set forth in claim 1, including keyhole slots in said flat base to aid in hanging the tray on a substantially vertical support for display.
Claim 6
Dependent Claim
25 words
A tray as set forth in claim 1, including a frusto-conical outer wall on each projection to engage the female threads on an oil filter.
Claim 7
Dependent Claim
51 words
A tray as set forth in claim 5, including a frusto-conical wall defining a recess in the underside of each of said projections with the recesses adapted to receive a corresponding projection of a second tray stacked beneath the first mentioned tray when said second tray is devoid of oil filters.
Claim 8
Dependent Claim
35 words
A tray as set forth in claim 1, wherein said projections are disposed on said flat base in a regular grid pattern with center-to-center distances being slightly greater than the diameter of the oil filters.
Claim 9
Dependent Claim
104 words
A shipping and display package for a plurality of engine oil filters comprising, in combination, a generally flat base, a plurality of engine oil filters of generally cylindrical form disposed on one side of said flat base, said filters having female threads and an annular gasket, securing means interconnecting said base and said filters and including a plurality of male projections protruding upwardly from and attached to said base, and said projections being of a semi-rigid material and engaged with said female threads on each oil filter to trap said annular gasket of said oil filter between said flat base and said oil filter.
Claim 10
Dependent Claim
104 words
A shipping and display package for a plurality of engine oil filters comprising, in combination, a generally flat base, a plurality of engine oil filters of generally cylindrical form disposed on one side of said flat base, said filters having female threads and an annular gasket, securing means interconnecting said base and said filters and including a plurality of male projections protruding upwardly from and attached to said base, and said projections being of a semi-rigid material and engaged with said female threads on each oil filter to trap said annular gasket of said oil filter between said flat base and said oil filter.
Claim 11
Dependent Claim
23 words
A package as set forth in claim 8, wherein said projections are deformed laterally by engagement with said female threads on said filters.
Claim 12
Dependent Claim
40 words
A package as set forth in claim 9, wherein each of said projections is a frusto-conical knob fixed to said base, and a recess in the underside of each knob to aid in establishing each knob as being laterally deformable.
Claim 13
Dependent Claim
31 words
A package as set forth in claim 10, wherein said knobs initially have relatively smooth outer walls and are deformed laterally by threaded engagement with said female threads on said filters.
Claim 14
Dependent Claim
17 words
A package as set forth in claim 8, wherein said projections are fixed on said flat base.
Claim 15
Dependent Claim
17 words
A package as set forth in claim 8, wherein said projections are unitary with said flat base.
Claim 16
Dependent Claim
35 words
A package as set forth in claim 8, including apertures in said base adjacent one side thereof to aid in hanging the package in a substantially vertical position for display of said oil filters thereon.
Claim 17
Dependent Claim
36 words
A package as set forth in claim 8, wherein said securing means includes an enveloping wrap of sheet material enveloping all of said filters and at least part of the opposite side of said flat base.
Claim 18
Dependent Claim
22 words
A package as set forth in claim 15, wherein said enveloping wrap is a transparent shrink-wrap material to display said oil filters.
