The disclosures made herein relate generally to liquid dispensing containers and, more particularly, to liquid dispensing containers having a vent structure promoting improved liquid dispensing.
It is well known that portable, handheld liquid dispensing containers are a type of liquid dispensing container that are available and useful in a number of shapes and sizes, and are made for a number of purposes. Such liquid dispensing containers are also well known to be useful for transporting and dispensing various types of liquids. Examples of these liquids include, but are not limited to, fuels, lubricants, water and the like.
It is desirable for liquid within an interior space of a portable, handheld liquid dispensing container to be dispensable through a dispensing structure of the container in a relatively smooth and uniform liquid flow. To this end, portable, handheld liquid containers include a vent structure that allows dispensed liquid to be replaced with ambient air. However, a common problem with many conventional portable, handheld liquid dispensing containers (and other types of liquid dispensing containers) is that the vent tube structure exhibits one of several shortcomings. One such shortcoming is that the vent structure is prone to allowing liquid to spill from the vent structure during dispensing when the liquid dispensing container is tipped beyond a certain container rotation amount. Another such shortcoming is that the construction of the vent offers an inadequate volumetric flow of ambient air into the interior space of the container. This inadequate volumetric flow of ambient air can cause all or a portion of the liquid in the container to not be dispensed in a suitably smooth and uniform liquid flow (e.g., to be dispensed with a “glugging” action) and/or can cause all or a portion of the liquid in the container to be dispensed at a less than optimal or preferred volumetric flow rate. Still another such shortcoming is that the construction of the vent is cumbersome to fabricate and/or integrate into the container. Still another shortcoming is that pouring contents of an often heavy dispensing container into a receiving container requires a user to precisely position a spout of such a heavy dispensing container relative to an inlet of the receiving container. The inability of the user to precisely position the dispensing container relative to the receiving container during such pouring often contributes to spilling of contents of the dispensing container during pouring.
Therefore, a liquid dispensing container (and particularly a portable, handheld liquid dispensing container) that overcomes one or more shortcomings associated with conventional portable, handheld liquid dispensing containers and other types of liquid dispensing containers would be advantageous, desirable and useful.
Embodiments of the present invention are directed to liquid dispensing containers exhibiting improved liquid dispensing and ease of operator dispensing. More specifically, embodiments of the present invention are directed to portable, handheld liquid dispensing containers having a vent structure that provides improved liquid dispensing (e.g., dispensing rate, dispensing uniformity/smoothness, and the like) along with simplified vent construction and container integration. In these regards, embodiments of the present invention advantageously overcome one or more shortcomings associated conventional portable, handheld liquid dispensing containers and other types of containers, facilitating dispensing of liquid contents thereby reducing unwanted and potentially dangerous spillage.
In one embodiment of the present invention, a liquid dispensing container comprises a liquid container having a plurality of walls defining an interior space therebetween, a venting device attached to a first upper one of the walls (i.e., the first upper wall) and a liquid delivery device mounting body attached to a second upper one of the walls (i.e., the second upper wall). The venting device includes a venting conduit within the interior space. A first end portion of the venting conduit is adjacent the first upper wall and a second end portion of the venting conduit is adjacent a bottom one of the walls (i.e., the bottom wall). The venting conduit includes a central passage extending between the first and second end portions thereof. The liquid delivery device mounting body has a central passage extending therethrough. The second upper wall is laterally spaced away from the first upper wall and is vertically spaced below the first upper walls relative to the bottom wall.
In another embodiment of the present invention, a liquid dispensing container comprises a liquid container, a venting device mounting body, a liquid delivery device mounting body and a venting device. The liquid container has an interior space therein that is at least partially defined by opposing sidewalls, opposing end walls, a bottom wall, a first upper wall and a second upper wall. The bottom wall is adapted for enabling the liquid container to rest thereupon when in a surface-supported container storage position. A first one of the end walls (the first end wall) is adapted for enabling the liquid container to rest thereupon when in a surface-supported liquid dispensing position. The venting device mounting body is attached to the first upper wall and has a central passage therein extending through the first upper wall. The liquid delivery device mounting body is attached to the second upper wall and has a central passage therein extending through the second upper wall. The second upper wall is laterally spaced away from the first upper wall. The second upper wall is vertically spaced below the first upper wall relative to the bottom wall. The liquid delivery device mounting body is located adjacent to the first end wall. The venting device is mounted on the venting device mounting body. The venting device includes a vent tube within the interior space. The vent tube has a first end portion attached to the venting device mounting body and a second end portion adjacent to the bottom wall. The vent tube includes a central passage extending between the first and second end portions thereof. The central passage of the vent tube is in liquid communication with an ambient environment surrounding the liquid container and with the interior space.
In another embodiment of the present invention, a liquid dispensing container comprises a liquid container including a plurality of walls, a vent tube mounting body, a liquid delivery device mounting body and a vent tube. An interior space, a first hand-gripping structure, a second hand-gripping structure, a first container support surface upon which the liquid container rests when in a surface-supported container storage position and a second container support surface upon which the liquid container rests when in a surface-supported liquid dispensing position are each jointly defined by a respective portion of one or more of the plurality of walls. The first hand-gripping structure is opposite the first container support surface and the second hand-gripping structure is opposite the second container support surface. The vent tube mounting body is attached to a first upper one of the walls (the first upper wall) that is adjacent to the first hand-gripping structure and has a passage therein extending through the first upper one of the walls. The liquid delivery device mounting body is attached to a second upper one of the walls (the second upper wall) that is adjacent to the first hand-gripping structure and has a passage therein extending through the second upper wall. The second upper wall is laterally spaced away from the first upper wall. The first hand-gripping structure is positioned between the first and second upper walls. The second upper wall is vertically spaced below the first upper wall relative to a bottom one of the walls (the bottom wall) that at least partially defines the first container support surface. The liquid delivery device mounting body is located adjacent to a container supporting one of the walls that at least partially defines the second container support surface. The vent tube is within the interior space. A first end portion of the vent tube is attached to the venting device mounting body and a second end portion of the vent tube is located adjacent to the bottom wall. The vent tube includes a central passage extending between the first and second end portions thereof.
