This disclosure generally relates to containers, and in particular, it relates to jars and the like with a non-uniform cross-section or periphery along its central axis, such as but not limited to a conical cross-section.
Existing canning jars are space-inefficient when they're empty, which is most of their usable life. Because canning jars are space-inefficient when empty, there's no compelling reason to manufacture and sell the same style of jars manufactured with differing materials. Because existing jars are space-inefficient when empty, and because the jars aren't manufactured using different materials, current canning jars cannot form a comprehensive storage system. Current canning jars typically do not have a pour spout. Existing food storage systems other than canning jar systems usually do not have measurement marks, and those systems like canning jars, that do have measurement marks, tend to only be in larger delineations, such as ounces and cups. Current canning jar systems also do not generally have any features to improve grip. Various existing canning jars are designed to make a seal under vacuum, but do not seal when internal pressure exceeds atmospheric or external pressure. Certain prior nesting containers can form a vacuum seal when nested together, even when moisture is present between the containers, however, prior nesting containers often have an unsteady or imperfect fit or seat when nested together.
Furthermore, existing food packaging jars and containers tend to be one-off, proprietary containers that eventually end up at the recycling center or the landfill. The lids for various prior containers are typically proprietary and divergent in size and configurations, such that they almost never fit any other brand of containers, and there are very few functional uses for such jars and lids once the original contents are consumed. Additionally, as prior jar and container systems are being shipped from the jar manufacturer to the food packager in the supply chain, they are very space-inefficient regarding transport as well as related increases in shipping costs. Accordingly, there is a need for an improved container system that addresses and overcomes such deficiencies.
The disclosed container system solves the problem of inefficient space usage caused by conventional canning jars, storage containers and the like, resulting in, for example, overcrowded, cluttered cabinets, drawers, pantries, as well as other locations in residences, commercial or transport locations. Additionally, the disclosed container system uses a standardized set of lids that allows one set of lids to fit many differing volume capacities of storage containers. The disclosed container system thereby averts the conventional problem of accumulation of orphaned and mismatched lids or containers that typically results over time using conventional storage containers from differing manufacturers.
Certain of the disclosed containers have an internal pour spout to aid in pouring liquids from the containers. The improved containers can be manufactured and sold in a variety of volumes and sizes. The containers can be manufactured in many types of materials, and yet still function together as a storage system. The containers are mathematically calculated to nest together in the most efficient way possible for each size, prioritizing both stability and space efficiency. The containers have an engineered cavity in the threads that keeps the lid sealed tightly against internal pressure. The containers have special protrusions that aid in gripping the containers, as well as providing a natural balance point when pouring.
Further aspects of the present disclosure will be more readily appreciated upon review of the detailed description of its various embodiments, described below, when taken in conjunction with the accompanying drawings, of which:
The improved jar/container systems introduced herein have various applications in the home, as well as medical, manufacturing, hobby, brewing, food packaging, food shipping, canning and other relevant industries. The disclosed container systems, in various embodiments, include two or more containers that are configured to nest inside of each other when empty. In certain cases, the containers are sized for compatibility with existing, standardized canning jar lids such as BALL, KERR, and other like manufacturers. When empty, the disclosed containers nest inside of each other in a similar manner to pint glasses or dixie cups, which translates to 50% or more space savings when not in use for food or liquid storage. In some embodiments, the disclosed container system is a system of individually nestable canning and storage jars, however all contemplated embodiments herein are not so limited and may include other similar containers. The containers of the disclosed container system, in differing embodiments, are composed of one or more of glass, plastic, polymer, metal, ceramics, rubber, stone, or other waterproof and durable materials or combinations of the same. In some embodiments described and shown herein, the disclosed containers are entirely made of glass, so as to be fully functional as conventional canning jars. In some embodiments, the containers are formed from a molding process. In some embodiments, the containers and lids are one or more of: transparent, translucent, opaque and/or have any one or more of a variety of colors, visual patterns, images, text, and the like, on the various surfaces thereof.
In various embodiments, the disclosed containers are provided in any of a wide variety of sizes. In the present disclosure, containers that hold a volume of 16 ounces (oz), 6 oz and 4 oz are referenced in various instances by way of example only. However, the disclosure and relevant embodiments described herein are not so limited. In various instances, the disclosed containers are necessarily tapered from top to bottom to facilitate nesting, thereby having a non-uniform circumference along the length of its central axis. In certain embodiments where the container is composed of glass, the wall thickness of the container is selected to withstand the rigors of the canning process. In various such cases, the angle of the taper of the exterior wall thereof is also specified to balance the wall thickness with the nesting aspect of the jars.
In various embodiments, the improved containers have a pour spout disposed on the inner wall at a top portion of the container for easier pouring or sipping, and finger grips of various configurations disposed and/or provided on the exterior wall thereof for easier grasping by a user. In various embodiments, the pour spout, with its particularly disclosed location within the inner wall extending toward the top of a container, doubles as an air gap to prevent the nested containers from adhering together due to moisture cohesion or suction, as experienced with various prior nesting containers. In various instances, the exterior walls of the disclosed containers additionally have internally- or externally-disposed measurement marks for more productive cooking uses. In some cases, the measurement marks contain indented or raised tic marks (configured such as, but not limited to dashes, dots, or a combination thereof) that are spaced apart and have visible numerical indication for volume measured in teaspoons, tablespoons, milliliters, ounces, ½ cups, cups and other useful English or metric units.
The improved container system introduced herein is designed to replace primarily four types of existing products: (1) canning jars like BALL, KERR, MASON etc., as typically used by home-based canners; (2) small storage containers (volume capacity of 4 oz-8 oz) for home kitchens and school lunches like those sold in retail stores by TUPPERWARE, GLAD, and the like, whose container products are primarily composed of plastic; (3) food packaging jars like those found in grocery stores for pickles, jams and the like (that are typically made from glass); and (4) reusable containers for coffee, water, and the like, either insulated and non-insulated. The disclosed container system significantly improves each of the above.
With respect to (1) above, existing canning jars are very space in-efficient when empty. Additionally, most canning jars are either used for canning or drinking. The disclosed container system is designed to also be used for everyday food storage like school lunches and leftovers, in addition to being fully functional canning jars. Moreover, because various embodiments of the disclosed container system use standard canning lids, they take advantage and are compatible/interchangeable with the existing market ecosystem and popularity of existing canning jar products. Lastly, the disclosed container system has several features that existing canning jars do not, namely, a pour spout, finger grips, and additional measurement markings.
With respect to (2)-(4) above, existing storage container systems for school lunches, leftover food storage or the like in the 4-16 oz range typically degrade as containers or lids are lost, resulting in orphaned lids or containers over time. Accordingly, the typical owner of conventional containers is left with extra lids that don't fit other containers, or conversely, extra containers with no fitted lids. Many proprietary manufacturers will either discontinue certain types of containers or change the design over time as well, so that it becomes difficult to find new lids for old containers.
The improved container system solves this and other problems by taking advantage of the existing value created by standardized and long-used canning jar lid sizes. The disclosed improved container system, in various cases, will fit the standard ever-present lids our grandparents used, which are the lids our grandchildren will likely continue to use. Additionally, the disclosed container system will be made of almost any material, so the lids for the glass jars will also cross-fit with the standard-sized lids of various materials, while remaining nestable and stackable with other like improved containers. Use of the disclosed container system by jar and food manufacturers would save considerable shipping and storage costs, as the disclosed container system, when empty, is at least 50% more space efficient than standard jars in volume sizes of 4-16 oz and higher, with increasing space efficiency resulting as more containers and greater volumes are used.
Referring now to
A core feature of the improved containers 10 is that they readily and stably nest inside of each other when they are empty. As a result, the available ratios of height to wall angle has been determined to fall within a narrow range. A formula can be manually or programmatically used to determine appropriate sizes and dimensions of the containers disclosed herein. For a given volume, the formula then calculates the appropriate mouth (top opening) size, the base (bottom) size, the height of the container, the angle of the exterior wall extending from the bottom, and the width of the exterior wall. In various embodiments, the interior of the wall is substantially parallel to the exterior of the wall in either one or more sections or the entirety thereof.
An exemplary useful formula for determining container dimensions and volume is V=(π*H)/3 (R{circumflex over ( )}2+R*r+r{circumflex over ( )}2) where “V”, “H”, “R” and “r” are volume, container height, larger mouth radius, and smaller base radius of the conical portion of the container 10, respectively. For any given volume, there are many ‘right’ answers, meaning that many different shapes will still result in jars that nest nicely inside of each other. However, wider bases are preferred as the first consideration so as to provide superior upright stability.
Canning jars, in particular, have fixed mouth sizes because they traditionally use the same lids. Typically, the outside diameter of the mouth size is either 81.6 millimeters (mm) for a “large mouth” jar, or 66.5 mm for a ‘small mouth jar.’ Because the container walls, in such embodiments, need to be about 3 mm thick in order to withstand the heat and pressure of canning, one subtracts 2 mm×3 mm=6 mm from the outside diameter to get the inside diameter. So, for an exemplary ‘large-mouth’ jar, a larger base radius (“R”) would be 81.6 mm-6 mm=75.6 mm.
In cases where it is undesirable for the liquid to go all the way to the top of the jar, it is necessary to leave a gap at the top of the container. When a preferred wall angle is known, one can employ an easy triangle calculation to figure out the diameter a certain percentage of the way down from the top of the container. In other instances, the wall angle 10R is variable and ranges between 4.01° and 10.75°. In many instances, 7° is a reasonable and useful baseline to use for the wall angle.
For the base, the outside diameter needs to be smaller than the inside diameter of the mouth for nesting, in various embodiments, and the nested container needs to be about the same size as the inside of the receiving container about two-thirds of the way down or within a reasonable and useful range thereof. The rim bottom 10C of a stacked container 10 rests on the top of the container 10 in which it is nested. In various embodiments, the diameter of the base must be less than the mouth width minus two times the wall thickness.
In various embodiments, the width of the wall may be constant and ranges between 2.3 mm and 4 mm are useful. In various embodiments, the interior/exterior wall angles between 4.062° and about 12° are useful.
While many containers can nest to some degree, not all combinations of wall angles, container heights and wall angles will nest ‘well’. If the wall thickness compared to the wall angle is too thick, the containers won't nest deeply. If the wall angle is too steep, the container will be inclined to tip. One of the key features of these storage containers is that the wall-angle, jar height, and wall thickness of the jars can be described by a range of ratios between two triangles, as described by the following:
Another related ratio that defines these containers is the wall angle compared to cosine of the wall thickness.
Where:
One can calculate the thickness t of the container at the mouth with the following:
0.18<r<0.78
In accordance with the improvements disclosed in the foregoing, an improved container 10 with a height (H), includes, in various embodiments, a substantially circular mouth having a rim 10M with a first radius (R), the rim 10M having a top edge and a bottom edge 10C, where the bottom edge 10C is provided to engage a second top edge of a second rim of a second container when the container and the second container are stacked. In such embodiments, the container 10 further includes a substantially circular base having a center and a second diameter (r) extending to an outer circumference, where the second radius is smaller than the first radius, and a wall having a thickness (t), the wall 10S continuously extending from the rim of the mouth to the outer circumference around a central axis defining the height of the container 10. In such embodiments, the wall is tapered to facilitate nesting and has a non-uniform circumference along an entire length of the central axis such that the wall forms a section of a cone, where an internal volume (V) of the container substantially satisfies the formula: V=(πH/3)(R{circumflex over ( )}2+R*r+r{circumflex over ( )}2).
In additional embodiments, a container 10 has a ratio of (i) a first area of a first right triangle having a first hypotenuse extending from the center 80A of the base to a point 80 B on an exterior edge of the rim of the container 10, to (ii) a second area of a second triangle having a second hypotenuse extending from the center 80A of the base to a point 80C on an interior edge of the rim is substantially between 0.601 and 0.839. In such embodiments, a ratio of the first area to the second area is substantially between 0.62 and 0.81. In additional embodiments, the wall 10S extends from the base 10X at an angle (0) substantially between 4.01° and 12° from vertical. In additional embodiments, the thickness (t) of the wall 10S is substantially between 0.5 millimeters (mm) and 4 mm and a thickness of the container 10 at the mouth (tmouth) is substantially equal to t/cos (0). In additional embodiments, a ratio of tmouth to θ is substantially between 0.18 and 0.78. In additional embodiments, an outside diameter of the mouth size is substantially between 66.5 millimeters (mm) and 81.6 millimeters (mm). in additional embodiments, a diameter of the base is less than a diameter of the mouth minus two times the thickness (t) of the wall. In additional embodiments, the thickness (t) of the wall 10S is substantially constant between the mouth 10M or the rim 10J and the base 10X. In additional embodiments, the outside diameter of the base is smaller than an inside diameter of the mouth 10M in order to accommodate nesting with the second container. In additional embodiments, a pour spout 10L is disposed on an inner portion of the wall 10S at a top portion of the container 10. In additional embodiments, the pour spout 10L functions as an air gap to prevent the container 10 and the second container from adhering together when nested due to moisture cohesion or suction. In additional embodiments, a bottom or base 10X of the container 10 reaches a bottom of the second container when stacked. In alternate embodiments, a bottom of the container 10 does not reach a bottom or base of the second container when stacked. In additional embodiments, an exterior of the wall 10S includes at least one finger grip 10G. In additional embodiments, an exterior or interior of the wall 10S includes at least one measuring mark delineating at least one of an English and a metric volume measurement. In additional embodiments, the measurement mark comprises at least one of a raised tic mark and an indented tic mark. In additional embodiments, the measurement mark is configured as at least one of a dash and a dot. In additional embodiments, a volume of the container 10 is the same as a volume of the second container with which it is nested or stacked. In additional embodiments, a volume of the container is different than a volume of the second container with which it is stacked or nested.
Although the best methodologies have been particularly described in the foregoing disclosure, it is to be understood that such descriptions have been provided for purposes of illustration only, and that other variations both in form and in detail can be made thereupon by those skilled in the art without departing from the spirit and scope thereof.
