Description

This invention relates to liquid containing and dispensing packages.

BACKGROUND AND SUMMARY OF THE INVENTION

In one type of liquid containing and dispensing package utilized, for example, in dispensing of liquid detergent a plastic container is provided with a spout and a combined measuring cup and closure is provided on the container. Typical patents showing various constructions are U.S. Pat. Nos. 4,671,421, 4,706,829, 4,863,067, 4,917,269 and U.S. Pat. No. 4,890,768.

Among the objectives of the present invention are to provide a liquid containing and dispensing package wherein the package can be easily assembled; wherein the part forming the spout can be inserted in the container and held in place utilizing various attaching methods; wherein the portion forming the spout can be pushed in and snapped in to place on the container; wherein the spout is radially prevented from rotating relative to the container, being removed from the container or taken off of the container by over-tightening of the closure; and where the combined measuring cup and closure seals against the spout and the spout seals against the container.

In accordance with the invention, the liquid containing and dispensing package comprises a plastic container having a finish defining an opening. The finish has an outer surface and an inner surface. At least two annular rows of circumferentially spaced lugs are provided on the outer surface of the finish. The lugs in one row are staggered circumferentially with respect to the lugs of an adjacent row. A spout is provided and has an annular outer wall, an annular inner wall and an integral portion connecting the annular walls. The outer wall of the insert has an inner surface with two rows of spaced recesses for receiving the lugs on the finish. The inner wall of the spout has an inner surface formed with a spiral thread receiving groove. The insert includes an axially extending spout connected to the lower edge of said inner wall and extending above the inner wall. A combined measuring cup and closure is provided and has an annular axial wall and a base wall and a radial flange intermediate the base wall and lower end of the axial wall. The portion of the axial wall of the combined measuring cup and closure beneath the flange includes threads on the outer surface thereof engaging the spiral thread groove on the insert.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1 the combined liquid containing and dispensing the package embodying the invention comprises a hollow blow molded plastic container 20 that includes a spout insert 22 and a combined dispensing cup and closure 24.

As shown in FIGS. 2-8, the plastic container 20 has a finish 26 with an integrally formed series of lugs 28, 30 in two rows (FIG. 5) and a flat top sealing surface 32. Lugs 28 are staggered circumferentially with respect to lugs 30. As shown in FIG. 4, the lugs 28, 30 are formed by being blown outwardly so that complimentary recesses 34, 36 are provided on the inner surface of the finish.

The spout insert 22 includes an outer wall 38 and an inner wall 40 combined by an integral transverse wall 42. The outer wall 38 is formed with two axially spaced rows of recesses 44, 46 that are complementary to and engage the lugs 28, 30 by a snap action to orient the spout insert 22 circumferentially. Such a construction also permits the assembly of the insert 22 to the container 20 at high speeds of assembly.

The inner wall 40 of the spout insert 22 includes a lower portion 48 that is connected to a spout portion 50 by an inclined bottom portion 52. The lower portion 48 of the spout insert 22 is provided with axially spaced opening 54. The spout insert 22 is further provided with a sealing rib 62 on the upper surface of transverse wall 42.

The combined measuring cup and closure is substantially identical to the disclosures shown in U.S. Pat. No. 4,917,269 and includes a base wall 64 and a depending annular peripheral wall 66. A radial flange 68 is provided intermediate the base wall on the lower edge of the wall 36 and external threads are provided below the flange. A primary flexible sealing ring is provided on the outer surface of the lower portion of the wall of the closure and extends at an angle outwardly and upwardly from the outer surface of the wall.

It can thus be seen that there has been provided a liquid containing and dispensing package wherein the package can be easily assembled; wherein the part forming the spout can be inserted in the container and held in place utilizing various attaching methods; wherein the portion forming the spout can be pushed in and snapped in to place on the container; wherein the spout is radially prevented from rotating relative to the container, being removed from the container or taken off of the container by over-tightening of the closure; and where the combined measuring cup and closure seals against the spout and the spout seals against the container.
