Container and blow mold assembly
A container for storing, transporting and dispensing fluids has a spout in the top proximate the front portion, a hollow handle open to the spout and the top of the container body proximate the rear portion and a handling indentation for manipulating the container to dispense liquid from the spout. Improved facilities for dispensing liquid comprise a channel dividing the handling indentation into segments whereby liquid flows through the channel from the rear of the container past the segments to the front of the container when the container is rotated to dispense liquid therefrom. A mold assembly comprises mating mold components comprising molding surfaces for producing a container in accordance with the invention.
1. Field of the Invention
This invention relates generally to containers for transporting, storing and dispensing liquids. In particular, this invention relates to blow molded containers having integral features for improving the facilities of the containers for dispensing liquids therefrom and to molds for such containers.
2. Description of Related Art
Containers of the type to which this invention pertains are characterized by large body cross sections relative to the mouth for filling and dispensing liquids therefrom. Typical of such containers the mouth is advantageously formed in a neck portion of the container comprising surface features for engaging a separable closure and forming a spout. It is known for such containers to comprise integral handles arranged at or proximate the top of the container body and to have one or more indentations known as “grips” in the base of the container for facilitating manipulation of the container to dispense fluids therefrom. In the prior art, such indentations restrain a portion of the fluid that would otherwise flow toward the mouth when the container base is rotated for dispensing the fluid. Consequently, such containers require exaggerated rotation in order to overcome the damming of liquid by the integral grip. Hence, there is a need for a container that overcomes the drawbacks of the known designs and improves the facilities of the containers for dispensing liquids therefrom.
It is known to produce containers to which the invention pertains by blow molding. Blow molding is a cyclic process wherein one or more parisons of material in a moldable condition are centered on the parting plane of a mold assembly; the mold assembly is closed around the parisons; the parisons are expanded so the exterior of each parison abuts molding surfaces defining a molding cavity of the closed mold assembly; the blow molded articles are conditioned to be sufficiently rigid to retain the molded size and shape while unsupported; the mold assembly is opened; and, the blow molded articles are removed. In general, the moldable condition of a parison is achieved when the material of the parison is at an elevated temperature, and the rigid condition of a blow molded article is achieved when the temperature of the material has been reduced. There is a need for molds for blow molding containers having improved facilities for dispensing liquids therefrom.
II. SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a container for transporting, storing and dispensing liquids comprising a body having front and rear portions and a spout in the top of the container proximate the front portion for dispensing fluids therefrom having integral features for improved dispensing of liquids therefrom.
A further object of the present invention is to provide a container for transporting, storing and dispensing liquids comprising a body having front and rear portions, a spout in the top of the container body proximate the front portion for dispensing fluids therefrom, a handling indentation in the container base for facilitating manipulation of the container to dispense fluids from the spout, and a channel in the container base continuous from the front portion to the rear portion and dividing the handling indentation into segments, liquid flowing through the channel from the rear of the container past the segments to the front of the container when the container base is rotated to dispense liquid from the spout.
It is a further object of the present invention to provide a mold assembly for producing containers in accordance with the invention.
Further objects and advantages of the invention shall be made apparent from the accompanying drawings and the following description thereof.
In accordance with the aforesaid objects the present invention provides a container for transporting, storing and dispensing liquids, the container comprising a body having front and rear portions, a spout in the top of the container proximate the front portion for dispensing fluids therefrom, a hollow handle open to the base of the spout and the top of the container body proximate the rear portion thereof and a handling indentation in the container base for facilitating manipulation of the container to dispense fluids from the spout. Improved facilities for dispensing liquid from the container comprise a channel in the container base continuous from the front portion to the rear portion and dividing the handling indentation into segments, liquid flowing through the channel from the rear of the container past the segments to the front of the container when the container base is rotated to dispense liquid from the spout.

Claims
1. A container for transporting, storing and dispensing liquids, the container comprising a body having front and rear portions, a spout in the top of the container proximate the front portion for dispensing fluids therefrom, a handling indentation in the container base for facilitating manipulation of the container to dispense fluids from the spout, and a channel in the container base continuous from the front portion to the rear portion and dividing the handling indentation into segments, liquid flowing through the channel from the rear of the container past the segments to the front of the container when the container is rotated to dispense liquid from the spout.
2. The container of claim 1 wherein the bottom of the channel is recessed from surrounding surfaces of the container base.
3. The container of claim 2 further comprising a hollow handle open to the spout and to the top of the container body proximate the rear portion and a groove traversing the top portion of the container between the spout and the connection of the handle with the top of the container body.
4. The container according to claim 2 further comprising at least three resting pads protruding from the container base and spaced apart from one another to define a plane, at least one resting pad located within the portion of the container base proximate the front portion of the container and at least one resting pad located within the portion of the container base below the rear portion of the container, the resting pads supporting the container when the container is stored upright.
5. A mold assembly for blow molding a container in accordance with claim 1, the mold assembly comprising first and second mating mold components, each mating mold component comprising molding surfaces open to a mating face of the mold component and defining the exterior of an article to be molded, the molding surfaces comprising first molding surfaces defining the container body, second molding surfaces defining the neck portion of the spout, and third molding surfaces defining the container base comprising a handling indentation for facilitating manipulation of the container to dispense fluids from the spout and a channel continuous from the front portion to the rear portion and dividing the handling indentation into segments, fluid flowing through the channel from the rear past the segments to the front when the container is rotated to dispense fluid from the spout.
6. The mold assembly according to claim 5 wherein the bottom of the channel is recessed from the surrounding surfaces of the container base.
7. The mold assembly according to claim 6 wherein the first molding surfaces further define a hollow handle open to the base of the spout and to the top of the container body proximate the rear portion and a groove traversing the top of the container between the spout and the connection of the handle to the top of the container body.
