DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to the drawings, FIGS. 1-9 show one embodiment of the plastic container of the present invention.

FIGS. 1-4 shows plastic container 10 of the present invention with container portion 12 and integral grip area 14. The container is a hollow, blow molded plastic container having a lower supporting base 16, a sidewall 18 extending upwardly from the base, a shoulder portion 20 extending upwardly from the sidewall, and a neck finish 22 extending upwardly from the sidewall and having an opening 24 to the inside of the container. The plastic container 10 has a generally oval base 16, see FIG. 8, and a generally oval opening 24 to the inside of the container, see FIG. 7.

The containers of the present invention are preferably made of a pliable, deformable, synthetic plastic material, such as for example, polyethylene, polypropylene, or polyethylene terephthalate (PET), or other plastic material, although PET is generally used.

The particular neck portion 22 shown in the drawings includes an upper flange portion 26 for a snap-on closure and/or a foil closure (not shown). However, other type neck finishes can be readily employed, as a threaded section to accommodate a screw-on closure. Also, the outer extent of the upper neck finish in the embodiment shown extends inwardly of the sidewall.

Plastic container 10 includes two, opposed first and second relatively larger sidewall portions 28, 30, respectively, and two opposed first and second relatively larger shoulder portions, 32, 34, respectively, which alternate with two opposed, first and second relatively shorter sidewall portions 36, 38, respectively, and two opposed relatively shorter shoulder portions 40, 42, respectively. The first relatively shorter sidewall portion 36 is relatively longer than the second of said relatively shorter sidewall portion 38. In addition, grip portion 44 is included on the first relatively shorter sidewall portion 36. The grip portion 44 is a hand or finger grip area which includes first and second spaced apart recessed portions 46 and 48, respectively, each of which is adjacent the grip area on the adjacent relatively longer sidewall portions. That is, first recessed area 46 is on the first relatively longer sidewall portion 28 and second recessed area 48 is on the second relatively longer sidewall portion 30. Thus, a convenient hand or finger grip area is provided which facilitates a strong and firm hold onto the container by the user.

As can be clearly seen from the drawings, the shoulder portions 20 extend upwardly and inwardly from the sidewall 18 to the neck finish 22. In addition, the integral grip area 14 is in the upper portion of the first relatively shorter sidewall portion 36 adjacent the shoulder portion. Moreover, the grip portion 14 and shoulder portion 20 are inwardly curved towards the opening 24 and the grip portion 44 preferably includes external ribs 50 spaced from each other to facilitate handling. At least two of these ribs are provided and preferably a plurality of the ribs are provided. In the embodiment shown in the drawings five spaced apart ribs are shown. The ribs desirably extend circumferentially around the grip area onto the adjacent relatively longer sidewall portions 28, 30.

The grip area 14 includes the curved external grip portion 44 and the recessed areas 46, 48. The recessed portions are each located on an adjacent longer sidewall portion, i.e., first recessed area 46 is located on first longer sidewall 28 and second recessed area is located on second longer sidewall 30. In addition, the second relatively shorter sidewall portion 38 and second shorter shoulder portion 42 include an inwardly curved, recessed pour area 54 beneath opening 24, which facilitates the dispensing operation.

Similarly, the neck finish area 22 includes two, opposed first and second relatively longer neck finish portions 56, 58, respectively, which extend upwardly from the first and second longer shoulder portions 32, 34, respectively, and two opposed first and second relatively shorter neck finish portions 60,62 respectively, which extend upwardly from the shorter shoulder portions 40, 42, respectively. The first relatively shorter neck finish portion 60 is relatively longer than the second relatively shorter neck finish portion 62 to provide a convenient dispensing or pour channel at the shorter neck finish portion 62. The dispensing function is enhanced by the recessed dispensing or pour area 54 beneath the second shorter neck finish portion 62 on the second shorter shoulder portion 42. The dispensing function is further enhanced by providing that the circumference of the neck finish opening 24 is smaller than the circumference of the base 16. In addition, the corners of the second shorter neck finish side portions have a round circumference to further facilitate dispensing.

Therefore, in accordance with the present invention the surface area of the opening 24 is smaller than the surface area of the base 16, with the ratio of opening 24 to base circumference being 1:1.4-2.5. In addition, the recessed portion 46, 48 beneath the grip area or handle 14 is at least 0.500 inch below the outer extent 60 of the curved external grip portion 44. This facilitates handling and simplified dispensing. In the embodiment shown in FIG. 9, the outer extent of the grip portion is 2.875 inches or 73.03 mm., and the outer extent of the recessed portion is 2.100 inches or 53.34 mm.

Thus, it can be seen that the plastic container of the present invention is extremely convenient for handling and dispensing contents. The upper grip area is opposed to the dispensing area and is convenient to use, and the sidewall, shoulder and neck finish features make the container quite easy to use. An additional advantage of the present container is that the container is readily stackable.

It is to be understood that the invention is not limited to the illustrations described and shown herein, which are deemed to be merely illustrative of the best modes of carrying out the invention, and which are susceptible of modification of form, size, arrangement of parts and details of operation. The invention rather is intended to encompass all such modifications which are within its spirit and scope as defined by the claims.
