Second bowl 16 includes a base 38 shaped as a disc, a cylindrical wall formed by a first radially thinner wall section 40 extending axially upward from base 38 and ring wall section 42 on top of wall section 40. Ring section 42 is radially thicker than wall section 40 and extends radially outward further than wall section 40 such than an outer circumferential surface 40a of wall section 40 is a greater distance from center axis C than an outer circumferential surface 42a of ring section 42. Base 38 includes a radially outer flat annular section 38a, a central disc section 38b intersecting center axis C and a second bowl engagement section formed by an axially protruding section 38c, in the shape of a ring, provided radially between section 38a and section 38b. Sections 38a, 38b are provided in the same plane as each other and section 38c protrudes axially above sections 38a, 38b.

More specifically, axially protruding section 38c extends axially from an upper surface 38d defined by sections 38a, 38b of base 38. Section 38c is hollow to define an annular recess 38e in a lower surface 38f of base 38 radially between sections 38a, 38b. Section 38c includes an upper radially outer axially extending surface 39a, an upper radially extending surface 39b and an upper radially inner axially extending surface 39c, and a lower upper radially outer axially extending surface 39d, a lower radially extending surface 39e and a lower radially inner axially extending surface 39f defining recess 38d. Upper radially outer axially extending surface 39a extends axially from upper surface 38d of section 38a to join upper radially extending surface 39b, which extends radially inward from surface 39a to upper radially inner axially extending surface 39c, which extends axially away from surface 39b to upper surface 38d of section 38b. Lower radially outer axially extending surface 39d extends axially from lower surface 38f of section 38a to join lower radially extending surface 39e, which extends radially inward from surface 39d to lower radially inner axially extending surface 39f, which extends axially away from surface 39e to lower surface 38f of section 38b.

For storage and transportation, second bowl 16 is insertable inside of first bowl 14 and lid 12 is connectable to first bowl 14 with second bowl 16 inside of first bowl 14. Axially protruding section 30c is sized and shaped for insertion into recess 38e of second bowl 16. More specifically, second bowl 16 is placed inside of first bowl 14 such that recess 38e of second bowl 16 is placed onto axially protruding section 30c of first bowl 14 such that second bowl 16 is radially fixed in place inside of first bowl 14. In other words, section 38c of second bowl 16 is engaged with section 30c of first bowl 14 to center second bowl 16 within first bowl 14. Upper surfaces 31a, 31b, 31c of section 30c of base 30 of first bowl 14 contact lower surfaces 39d, 39e, 39f of section 38c of base 38 of second bowl 16, while upper surfaces 30d of sections 30a, 30b of base 30 of first bowl 14 contact lower surfaces 38f of sections 38a, 38b of base 38 of second bowl 16.

As shown by FIG. 6 and the enlarged view shown in FIG. 7, after second bowl 16 is centered within first bowl 14 by the contact between engagement sections 30c, 38c, lid 12 is connected to first bowl 14 by inserting lip 20 radially between first bowl 14 and second bowl 16. Lip 20 is forced downward into an annular space 44 formed radially between the outer diameter of second bowl 16 and the inner diameter of first bowl 14 such that upper surfaces 26a of protrusions 26 axially contact lower surfaces 36a of protrusions 36 and an inner circumferential surface 20c of lip 20 radially contacts outer circumferential surface 42a of ring section 42. At the same time, an upper surface 14b of first bowl 14, which forms a rim of first bowl 14, contacts a lower surface 12a of lid 12 at an outer periphery of base 18 that is outside of lip 20 and an upper surface 16a of second bowl 16, which forms a rim of second bowl 16, contacts a lower surface 28a of lid 12 at a portion of base 18 that is directly radially adjacent to lip 20 radially inside of lip 20. Inner circumferential surface 20c of lip is tapered such that surface 20c extends radially outward while extending axially away from base 18 such that surface 20c is wedged onto ring section 42 with an upper end of outer circumferential surface 42a of ring section 42 contacting the upper end of inner circumferential surface 20c. The engagement of protrusions 26 of lid 12 with protrusions 36 of first bowl 14 connects lid 12 to first bowl 14 while the engagement of inner circumferential surface 20c of lip with outer circumferential surface 42a and the engagement of section 30c of first bowl 14 with section 38c of second bowl 16 hold second bowl 16 radially in place inside of the first bowl 14 and lip 20. In the illustrated embodiment, the upper surfaces 26a of protrusions 26 can be forced into the lower surfaces 36a of protrusions 36 by the rotation of lid 20 due to the semi-helical shapes of protrusions 26, 36.

The portable bowl assembly 10 can used to transport pet food inside of second bowl 16 when lid 12 is secured to first bowl 14 with second bowl 16 secured inside of first bowl 14 by first bowl 14 and lid 12. Second bowl 16 is held axially in place inside of first bowl 14 and lid 12 by being axially sandwiched between base 30 of bowl 14 and base 18 of lid 12. More specifically, second bowl 16 is held axially in place inside of first bowl 14 and lid 12 by lower surface 38f of bowl 16 contacting upper surface 30d of bowl 14 and by upper surface 16a of bowl 16 contacting lower surface 28a of lid 12. Second bowl 16 is held radially in place inside of first bowl 14 and lid 12 by being radially held in place by engagement section 30c of bowl 14 and lip 20 of lid 12. More specifically, second bowl 16 is held radially in place inside of first bowl 14 and lid 12 by engagement section 38c of bowl 16 radially contacting engagement section 30c of bowl 16 and by outer circumferential surface 42a of bowl 16 contacting inner circumferential surface 20c of lid 12.

In order to provide food and water to a pet, lid 12 can be removed by disconnecting lid 12 from first bowl 14. In the illustrated embodiment, the removal of lip 12 can be accomplished by disengaging protrusions 26a of lid 12 from protrusions 36 of bowl 14 by rotating lid 12 in the direction opposite of the direction lid 12 was rotated to secure lid 12 into place on first bowl 14. After lid 12 is removed, it is designed to be flipped over and laid on the ground with surface 18a of lid 12 on the ground with support sections 28 facing upward. Second bowl 16 can then be placed onto lid 12 with engagement section 38c positioned on top of axial protrusions 28b of support sections 28 such that axial protrusions 28b are received in recesses 38e and edges 28c contact surfaces 31a and/or surfaces 31c to center second bowl 16 on lid 12. As shown in FIG. 7, lid 12 is formed by a base material 12c that is cover with a layer 12d of a non-slip material having a greater coefficient of friction than base material 12c to generate friction with the ground that prevents lid 12 and bowl 16 from sliding while the pet is eating food out of second bowl 16. First bowl 14 can also be placed on the ground and filled with water. A layer of non-slip material is also provided on lower surface 30f of first bowl 14 in the form of segments 46 having a greater coefficient of friction than a base material 14c to generate friction with the ground that prevents bowl 14 from sliding while the pet is drinking water out of first bowl 14. The non-slip material may be made of silicon or plastic and the remainder of lid 12 and bowls 14, 16, including base materials 12c, 14c, may be made of biodegradable plastic.

In the preceding specification, the invention has been described with reference to specific exemplary embodiments and examples thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative manner rather than a restrictive sense.
