FIELD
The present disclosure relates to blown plastic containers, and more particularly to plastic containers having a liquid dispensing apparatus.
BACKGROUND
The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art.
Plastic containers have been used to package liquids intended for various purposes including, for example, consumable beverages and cleaning detergents among other common purposes. Some plastic containers have been improved to include dispensing systems thus making it easier for the user to remove the liquid from the container. Liquid laundry detergents, in particular, have been packaged into newly designed plastic containers that have been constantly increasing in volume and weight. The increased size and weight of packaging creates a new set of challenges that heightens the need to improve dispensing systems. A further challenge to domestic chores is to improve efficiency while becoming more environmentally sensitive. Using the correct amount of liquid for a particular purpose lessens the effect on the environment while accomplishing accurately dispensing the proper amount of liquid.
While current plastic container dispensing systems are useful for their intended purpose, there is room in the art for an improved plastic container dispensing system that reduces or eliminates the need to lift heavy containers, improves efficiency, and enhances environmental stewardship.

The locking flange 144 is formed from an annular member 146, a pair of locking tabs 148 extending radially outward from the annular member 146, and a plurality of flexible overlapping tabs 150 extending radially inward from the annular member 146. The locking flange 144 is fixed to the open end 143 of the dosing cap 142 and is configured to perform two duties. The first is to lock the dispensing apparatus 114 into a locked position engaging the locking mechanism 140 by fitting the locking tabs 148 into the vertical grooves 136 of the collar 126, forcing the dispensing apparatus 114 in the downward direction until the locking flange 144 is in contact with the collar base 130, and twisting or rotating the dispensing apparatus 114 to slide the locking tabs 148 into the horizontal slot 138 of the collar 126 thus preventing the dispensing apparatus from returning to a first, unlocked position.
The second function or duty of the locking flange 144 is to receive the tube 128 from the plastic container 112 so that an open end 152 of the tube 128 extends between the overlapping tabs 150 into the dosing cap 142. In this manner, the liquid from the plastic container 112 is delivered to the dosing cap 142 via the tube 128 passing through the overlapping tabs 150 of the locking flange 144.
Referring now to FIG. 10, three operating positions A, B, C of the dispensing apparatus 114 are shown and will now be described. In a first of the three operating positions A, the end 143 of the dispensing apparatus 114 is disposed near the top of the collar 126 and the tube 128 has slightly penetrated the overlapping tabs 150 of the locking flange 144. The locking flange 144 is in contact with the outer wall 132 of the collar creating an airtight seal. In a second of the three operating positions B, the end 143 of the dispensing apparatus 114 has been pressed downward towards the base 130 of the collar 126 thus forcing the air contained by the seal between the locking flange 144 and the collar 126 into the dosing cap 142 and down the tube 128 into the plastic container 112. In a third of the three operating position C, the dosing cap 142 is forced upward from the base 130 of the collar 126 and draws a measured dose of liquid 154 from the plastic container 112, up the tube 128 and into the dosing cap 142. The measured does is arranged to provide a dose volume of between about one (1) and about two (2) oz. of liquid.
Turning now to FIGS. 12-14, another example of a plastic container and dispensing apparatus 200 is illustrated and will now be described. The plastic liquid container and dispensing apparatus 200 includes a plastic container 202 and a dispensing apparatus 204. The plastic container 202 includes a base 206, a body 208, and a dispensing portion 210. The body 208 may have a generally aesthetic design; however, most examples will include a handle 212 and a label portion 214. More specifically, the handle 212 includes integrated ribs 216 and a radius portion 218. The integrated ribs 216 provide strength to the handle 212 and the radius portion 218 follows the shape of the label portion 214.

The second end 232 is captured or retained by squeeze ball 228 and includes an opening 236 to the interior of the pick-up tube 226. The squeeze ball 228 includes a hollow interior and a plurality of gradation markings 238. For example, the collar of the squeeze ball 228 captures second end 232 of the pick-up tube 226 so that the interior of the pick-up tube 226 is in communication with the interior of the squeeze ball 228. The plurality of gradation markings 238 are disposed on the exterior of the squeeze ball 228 and mark the proper volume of liquid required for a particular application. The squeeze ball 228 may be molded with a non-opaque material so that the liquid level in the squeeze ball 228 can be determined. The first end 230 of the pick-up tube 226 of the dispensing apparatus 204 comes to rest in close proximity to the base 206 of the container 202. In this regard, the first end 230 of the pick-up tube 226 is below a liquid level of the plastic container 202 until there is very little liquid left in the container thus displaying that the pick-up tube 226 is capable of retrieving nearly all of the liquid out of the container 202.
Turning now to FIGS. 15-17, another example of a plastic container and dispensing apparatus 300 is illustrated and will now be described. The plastic liquid container and dispensing apparatus 300 includes a plastic container 302 and a dispensing apparatus 304. The plastic container 302 includes a base 306, a body 308, and a dispensing portion 310. The body 308 may have a generally aesthetic design; however, most examples will include a handle 312 and a label portion 314. More specifically, the handle 312 includes integrated ribs 316 and a radius portion 318. The integrated ribs 316 provide strength to the handle 312 and the radius portion 318 follows the shape of the label portion 314. The dispensing portion 310 of the plastic container 302 is disposed at the top of the plastic container 302 opposite the handle 312 and includes a siphon tube 320, a threaded vertical wall 322, and a cap 324.

The ends 326, 328 of the siphon tube 320 each have a port 330, 332 such that the interior of the plastic container 302 is in communication with the exterior of the plastic container 302 through the siphon tube 320. The cap 324 includes a hinge 325 and a retainer portion 327 and is hinged to the dispensing portion 310 of the plastic container 302 and operable to snap tight to the dispensing portion 310 locking the dispensing apparatus 304 in place while being capable of swinging clear of the dispensing portion 310 thus allowing the dispensing apparatus 304 to be removed from the dispensing portion 310.
The dispensing apparatus 304 is disposed on the dispensing portion 310 of the plastic container 302. The dispensing apparatus 304 includes a pick-up tube 334, a threaded collar 336, and a collapsible squeeze ball 338. The pick-up tube 334 is a gradually narrowing tube having a first end 340 and a second end 342 opposite the first end 340. The first end 340 has an opening 344 so that the interior of the pick-up tube 334 is in communication with the interior of the siphon tube 320 of the plastic container 302. The second end 342 is captured or retained by the threaded collar 336 and includes an opening 346 to the interior of the pick-up tube 334. The squeeze ball 338 includes a hollow interior, a collar, and a plurality of gradation markings 348. For example, the collar of the squeeze ball 338 is captured by the threaded collar 336 so that the interior of the pick-up tube 334 is in communication with the interior of the squeeze ball 338. The plurality of gradation markings 348 are disposed on the exterior of the squeeze ball 338 and mark the proper volume of liquid required for a particular application. The squeeze ball 338 may be molded with a non-opaque material so that the liquid level in the squeeze ball 338 can be determined. As FIGS. 16 and 17 details the interior of the plastic container 302 is shown. In this view, it is shown that the exterior of the pick-up tube 334 is sealed against the interior of the syphon tube 320 of the dispensing portion 310 of the plastic container 302. Furthermore, the first end 326 of the pick-up tube 320 of the dispensing portion 310 of the plastic container 302 terminates in close proximity to the base 306 of the container 302. In this regard, the first end 330 of the pick-up tube 320 is below a liquid 350 level of the container 52 until there is a minimal amount of liquid left in the container 302 thus displaying that the pick-up tube 320 is capable of retrieving nearly all of the liquid out of the plastic container 302.
When operating the dispensing apparatus 304, the collar 336 of the dispensing apparatus 304 is threaded onto the dispensing portion 310 of the plastic container 302. The squeeze ball 338 is compressed to force air down the pick-up tube 334, into and down the syphon tube 320, and into the plastic container 302. Next, the squeeze ball 338 is released and expands to draw a measured dose of liquid from the plastic container 302, up the syphon tube 320, the pick-up tube 334, and into the squeeze ball 338. The dispensing apparatus 304 is then twisted off from the dispensing portion 310, the pick-up tube 334 is removed from the plastic container 302, and aimed at the target to dispense liquid coming out of the compressed squeeze ball 338.
The description of the invention is merely exemplary in nature and variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
