The present disclosure relates generally to cover members or lids for enclosing contents in a container. More specifically, the present disclosure relates to cover members having vent handle arrangements thereon.
Various materials (i.e., solids and/or liquids) can be transported in containers, such as, for example, cans or buckets. Often the containers are provided with a cover for allowing access to the contents within. As a portion of the material is removed, it is sometimes desired to evacuate the air above the contents while reclosing the container to preserve the freshness of the contents stored in the container. The excess air in the container can cause the contents to become oxidized and lead to staleness. Internal vent cover arrangements have been developed to do this. Examples, such as covers or lids, are disclosed in U.S. Pat. Nos. 7,494,025; 3,578,467; and 2,726,012; the complete disclosures of these references are incorporated herein by reference. Improvements in covers or lids relating to venting and use, are desirable.
One aspect of the present disclosure relates to an internal cover/vent handle arrangement for enclosing contents in a container. The internal cover/vent handle arrangement includes a main cover body that can have an outer perimeter; and, opposite exterior and interior surfaces. The internal cover/vent handle arrangement can include a vent arrangement that extends through the main cover body. A vent handle arrangement is provided that includes a handle member; and, a squeeze-actuated vent valve arrangement configured to have a first, open, squeezed orientation in which the vent arrangement is open to permit a passage of air through the main cover body; and, a second, closed, release orientation in which the vent arrangement is closed to the passage of air through the main cover body. The internal cover/vent handle arrangement further can include a deflectable outer seal arrangement oriented in extension around the outer perimeter of the main cover body. The deflectable outer seal arrangement can include a deflectable perimeter flange arrangement that can have a rest shape that extends non-orthogonal to a direction between the exterior and interior surfaces of the main cover body.
Use of cover arrangements of the type characterized in U.S. Pat. No. 7,494,025 B2, is limited because of how they are configured for proper operation. This is because the design, as explained in U.S. Pat. No. 7,494,025 B2, is configured to be used specifically with a cylindrical wall, not a tapered wall, so it is limited in its application.
Also, cover arrangements of the type characterized in U.S. Pat. No. 7,494,025 B2, require that a handle rotate between upper and lower positions (i.e., during venting and closing). Thus, the handle must be kept free of material that may interfere with it. Also, this can be cumbersome to manage, if the cover arrangement is used inside a deep receptacle. For example, when using a 5 gallon bucket, a larger cover arrangement is used. Typically, a large cover arrangement will have a tendency to tilt when inside the 5 gallon bucket, and using a rotatable or hinged cover will exasperate the tilt.
Improvements are provided herein that can be applied differently from the arrangements explained in U.S. Pat. No. 7,494,025 B2, for example. These improvements and techniques are described below.
A. General
In general, 5 gallon pails or buckets, or other types of containers, are widely used to store and/or ship various materials. A 5 gallon bucket will be the preferred container in the examples of the present disclosure provided herein, although alternatives are possible. Typically, a bucket can be used to store contents (solids or liquids) that are atmosphere sensitive. In particular, a bucket can be used to keep the air volume above stored material relatively low so that the atmosphere sensitive contents within the bucket are not affected.
Such a bucket,
Second, the bucket will typically have a rim positioned generally around a portion of the bucket to permit empty buckets to be stacked before or after use and easily separated without sticking together in absence of a lid. Third, the bucket will typically have a handle (not shown in
As the material inside the bucket is removed, there is sometimes a desire to have an internal cover that can be pushed down inside the bucket, toward the material, in order to vent out extra atmosphere from above the material stored inside the bucket. This helps to keep the contents within the bucket fresh and free from oxidation. A feature of the present disclosure is that features, for venting atmosphere inside containers, are provided that can, if desired, be used with a variety of arrangements.
The example internal cover/vent handle arrangement is an improvement because it allows for advantageous venting from immediately above the material so that the material is less exposed to air, even in slanted wall, deep, buckets. The internal cover/vent handle arrangement, according to the present disclosure, is different in two primary ways. First, a squeeze-actuated vent valve arrangement, that allows air to vent from a bucket, is arranged and configured to be easily operated even while deeply recessed in the bucket, without the potentially cumbersome step of moving valves, by, for example, having to rotate a handle. Second, the internal cover/vent handle arrangement disclosed is also an improvement because it has a seal arrangement that can manage slanted walls.
A vent handle arrangement, as characterized herein, includes a handle member and a squeeze-actuated vent valve arrangement, although alternatives are possible. In general, the vent handle arrangement can be gripped by a user to easily trigger and move the vent handle arrangement to a first, open, squeezed orientation; and, a second, closed, release orientation. This configuration is convenient because there is no need to rotate or move up or down the vent handle arrangement. Also, the vent handle arrangement can be easily accessed deep inside the bucket to vent atmosphere by a simply using one hand to trigger the vent handle arrangement. This type of vent handle arrangement can be used with any type of seal to allow for a variety of arrangements. The vent handle arrangement will be described in further detail below.
Again, a deflectable outer seal arrangement can be configured to seal to a slanted sidewall of a bucket, although alternatives are possible. The deflectable outer seal arrangement preferably includes a deflectable perimeter flange arrangement that has a rest shape (shape when not installed) that extends non-orthogonal to a direction of a main cover body of the internal cover/vent handle arrangement. As a result, the deflectable perimeter flange arrangement is configured to seal against a changing diameter of a bucket. Of course, such deflectable perimeter flange arrangement can be used to seal against non-slanted surfaces, but it is particularly desired for slanted wall containers.
The deflectable outer seal arrangement of the internal cover/vent handle arrangement can be used together with the vent handle arrangement or different type of vent valve.
B. An improved Vent Valve Arrangement;
The reference numeral 10,
The example internal cover/vent handle arrangement is an improvement over the types of valve arrangements described in U.S. Pat. No. 7,494,025 B2, because the improved internal cover/vent handle arrangement does not have to be rotated between venting and closing positions such that it can interfere with contents or materials within a bucket.
In the example depicted, the container 14 includes an optional rim element 16 that extends from a sidewall 18 of the container 14 and forms a flat annular ledge 20. The rim element 16 can be integral with (e.g., forming in one piece with) or coupled to, the container 14, although alternatives are possible. Such a structure permits empty containers to be stacked without sticking in absence of a lid (not shown). In certain examples, the container 14 may include a handle (not shown). An inner surface 146 of the sidewall 18 of the container 14 can include a tapered portion 152,
Referring to
In the example depicted, the vent arrangement 11 is shown as an opening that permits air to flow from outside the container 14 to inside the container 14 (when the improved internal cover/vent handle arrangement 12 is lifted) and air to flow from inside the container 14 to outside the container 14 (when the improved internal cover/vent handle arrangement 12 is pushed downward).
The example vent handle arrangement 24 shown includes a handle member 64 (i.e. stationary handle member) and a squeeze-actuated vent valve arrangement 34, although alternatives are possible. Herein, the term “stationary” is generally used to mean that there is no movement of the components, relative to other parts of the main cover body 22, when grasped. In other words, the handle member 64 is fixed.
The handle member 64 is positioned on the exterior surface 13 of the main cover body 22, although alternatives are possible. In
The example squeeze-actuated vent valve arrangement 34 shown includes a moveable, squeeze-actuated, valve member 17 that is positionable between a portion of the handle member 64 and the vent arrangement 11. The handle member 64 and the moveable, squeeze-actuated, valve member 17 are configured such that an operator or user can simultaneously grip the handle member 64 and the moveable, squeeze-actuated, valve member 17 together to squeeze and move the vent handle arrangement 24 to a first, open, squeezed orientation 136 (see
In the first, open, squeeze orientation 136, the vent handle arrangement 24 is opened to permit a passage of air flow 116 through the main cover body 22. In the second, closed, release orientation 138, the vent handle arrangement 24 is closed to block a passage of air flow 116 through the main cover body 22.
Turning again to
The moveable, squeeze-actuated, valve member 17 includes at least one seal pad 60 (see
The example vent handle arrangement 24 shown also includes resilient seal arrangements 118 (

The example vent handle arrangement 24, according to the present disclosure, can be used with a variety of seal arrangements.
C. An Improved Deflectable Outer Seal Arrangement
Referring to
In general, the example deflectable outer seal arrangement 26 shown includes a deflectable perimeter flange arrangement 142. The deflectable perimeter flange arrangement 142 depicted includes a seal member portion 141 and an attachment base 140. The attachment base 140 surrounds, and is secured to, the outer perimeter wall 29 of the main cover body 22. The attachment base 140 of the example deflectable outer seal arrangement 26 shown is configured to be received within a recess groove 96 (see
The deflectable perimeter flange arrangement 142 is integral with (e.g., forming in one piece with) or coupled to, the attachment base 140. The example deflectable outer seal arrangement 26 has a circular shape.
The deflectable perimeter flange arrangement 142 is configured with a rest shape that extends non-orthogonal to a direction between the exterior and interior surfaces 13, 15 of the main cover body 22.
The deflectable perimeter flange arrangement 142 depicted is configured to form an upper acute angle of extension 144 (see
The example deflectable perimeter flange arrangement 142 shown is not necessarily of a straight, conical, shape of extension. For example, as depicted, the deflectable perimeter flange arrangement 142 is bowed having a somewhat upper, concave, surface 23 and an opposite, lower, convex sealing surface 25.
The example deflectable perimeter flange arrangement 142 shown provides a sliding seal along a slanted inner surface 146 of the sidewall 18 of the container 14. The example deflectable perimeter flange arrangement 142 shown can be used with a variety of alternate vent arrangements and alternate containers, including cans and/or jars.
D. Selected Features and Variations
1. Vent Valve Arrangement
Turning again to
The example cap member 100 shown defines a recess 110 at the first end 104 and a recess 112 at the second end 106 that are located adjacent to the ribs 108. As shown, the recesses 110, 112 each define apertures 114 for the passage of air flow 116 (see
It is desired to have the resilient seal arrangement 118 in an appropriate place for the internal cover/vent handle arrangement 12 to work. To do that, the example vent valve arrangement 24 shown includes a platform member 122 that has a body 124. The body 124 defines cutouts 126 on opposing sides 128, 130 of the body 124. The example platform member 122 shown includes a frame 132 (see
As shown, the resilient seal arrangement 118 includes slits 120 that align with the apertures 114 in the recesses 110, 112 to allow for the passage of air flow 116 therethrough, although alternatives are possible. The resilient seal arrangements 118, when used, will typically comprise a resilient material, such as, for example silicone rubber.
The seal pads 60 cover or seal the apertures 114 and the slits 120 to close a portion of the vent arrangement 11 extending therethrough, when the vent handle arrangement 24 is in a second, closed, release orientation 138. The vent arrangement 11 can include a plurality of vent openings and the movable, squeeze-actuated, valve member 17 can have a plurality of seal pads 60, for example with one each configured to close an associated one each of the vent openings, when the vent handle arrangement 24 is in a second, closed, release orientation. Of course, one pad 60 can be configured to close more than one vent opening.
The example squeeze-actuated vent valve arrangement 34 shown includes a moveable, squeeze-actuated, valve member 17 that has a support bar 36, a first leg 38 extending downwardly from the support bar 36, and an opposing second extending leg 40 extending downwardly from the support bar 36, although alternatives are possible. The example moveable, squeeze-actuated, valve member 17 shown includes seal pads 60 at free ends 62 of both of the respective first and second extending legs 38, 40. The seal pads 60 shown can be integral with (e.g., formed in one piece with) or coupled to, the two opposing upright walls 44, 46.
The example support bar 36 shown is integral with (e.g., formed in one piece with) or coupled to, the first and second extending legs 38, 40. The support bar 36 has two opposing upright walls 44, 46 extending therefrom that together form a channel 48 therebetween.

Referring to
Upon actuation of the vent valve arrangement 24, the at least one seal pad 60 is raised or lifted to allow for the passage of air flow 116 through the vent arrangement 11. The at least one seal pad 60 closes a portion of the vent arrangement 11 through both the apertures 114 of the cap member 100 and the slits 120 of the resilient seal arrangements 118. In the second, closed, release orientation 138, the seal pad 60 is lowered to cover the apertures 114 of the cap member 100 and the slits 120 of the resilient seal arrangements 118 to block air flow 116 therethrough, such that the passage of air flow 116 through a portion of the vent arrangement 11 is closed.
The outer perimeter 28 of the main cover body 22 extends around a central axis 30 (
The central surface portion 33 shown is recessed relative to the upper end 31 of the main cover body 22.
The outer perimeter wall 29 of the main cover body 22 includes an upper, radially outwardly extending, projection 94 and an opposite lower, radially outwardly extending, projection 92 with a peripheral, recessed, groove 96 therebetween. The upper and lower projections 92, 94 are parallel to one another as they extend radially outward from the main cover body 22.
Turning again to
The example vent valve arrangement 24 further includes a biasing arrangement 98 arranged and configured over tab members 88 located on both the squeeze-actuated vent valve arrangement 34 and the handle member 64 for resiliently biasing the moveable, squeeze-actuated, valve member 17 to a second, closed, orientation. In the example depicted, the biasing arrangement 98 includes at least one coil spring 99 (
2. Deflectable Outer Seal Arrangement
The upper acute angle of extension 144 (
Referring to
The example deflectable perimeter flange arrangement 142 has a radial outward dimension of extension D2 of at least 10 mm. Typically, the deflectable perimeter flange arrangement 142 has a radial outward dimension of extension D2 of no more than 80 mm. Often, the deflectable perimeter flange arrangement 142 has a radial outward dimension of extension D2 of at least 10 mm and no more than 60 mm. (preferably no more than 40 mm or 50 mm.)
The example deflectable perimeter flange arrangement 142 and the attachment base 140 shown define a pivot point 150 around which the deflectable perimeter flange arrangement 142 flexes when sealing against the slanted inner surface 146 of the sidewall 18.
The deflectable perimeter flange arrangement 142 can include a unitary skirt member 32 (see
The deflectable perimeter flange arrangement 142 has an upper surface 23 and an opposite, lower sealing surface 25. The lower sealing surface 25 includes a plurality of radial ribs 27 thereon. When the main cover body 22 is inserted within the container 14, the deflectable perimeter flange arrangement 142 is configured to seal against the sidewall 18 of the container 14.
The deflectable outer seal arrangement 26 can be formed from a molded plastic (i.e., polypropylene), although alternatives are possible. The advantage of forming the deflectable outer seal arrangement 26 as a molded plastic is the ability to easily form various shapes and sizes of the deflectable outer seal arrangement 26.
E. General Method
In accord with the present disclosure, a method of venting a container including: squeezing a vent handle arrangement configured on an internal cover; and pushing the internal cover along an inside of a container with a slanted sidewall while the internal cover is in sealing engagement with the slanted sidewall. These techniques can be practiced with the specific arrangements shown, but alternatives are possible.
Again, the principles, techniques, and features described herein can be applied in a variety of arrangements, and there is no requirement that all of the advantageous features identified be incorporated in an assembly, arrangement or component to obtain some benefit according to the present disclosure.
F. Example Uses
In accord with the present disclosure, the improved internal cover/vent handle arrangement can be used with containers to store a variety of items. These items can be commercial uses, hardware uses, home uses, farm/ranch uses, or military uses.
For example, items that can be stored include items that will degrade through contact with air such as food including: coffee, rice, seed, farm animal feed (cat, horse, etc.) or hardware items such as paint.
The present disclosure relates to two general concepts. One concept relates to a vent handle arrangement having a squeeze-actuated vent valve arrangement that provides for venting from immediately above material in a bucket, even in slanted wall, deep, buckets. Another concept relates to a deflectable outer seal arrangement that can provide a sealing engagement with a slanted sidewall of a container. In this summary, some selected, final summary characterizations of the teachings herein are provided. Among them are:
