  • US7090088 discloses a combination of a molded plastic bucket and a tamper-evident closure with a zig-zag tear strip which permits the removal of a portion of the lowermost closure flange.
  • the wedging and locking functions associated with the design of the edge or skin of the closure provide an improved and more permanent seal of the closure to the bucket.
  • Such a feature provides multiple buckets each of which is closed by a closure that enables easy slacking.
  • US8342354 discloses a molded plastic container with a "snap-ring" which acts as a transition structure between the container and the closure.
  • An inverted u-shaped slot in the snap rig fits to the top edge of the container r ⁇ transfer vertical stacking loads from the closure or ring to the container sidewall.
  • US6845877 discloses a plastic container with a snap closure and a snap element.
  • the invention fulfils the special demands imposed on lcak-proofncss, while simultaneously providing high load-bearing capacity.
  • US7740149 discloses apparatus and methods related to containers having a sidcwall portion with vertical corrugation therein.
  • the containers can be of a variety of shapes, sizes, cross- sections, and materials.
  • the corrugation improves the container sidcwall strength and resistance to buckling under compressive loads such as stacking of multiple containers.
  • L'S35670I6 discloses a new and improved sealed container assembly with sealing connection between the closure and the open end of the container.
  • the sealing consists of a multiple number of associated parts which reinforce each other and provide a high degree of stiffness at the open end of the container sufficient to withstand the usual rough handling to which shipping containers are subjected.
  • CA26764100 discloses container with axially extending, circumferentially distributed ribs stack inside of the container wail.
  • the stacking ribs serve to allow the stacking of several containers into each other.
  • Each upper container can be supported in the respective lower container, such that the two cone-shaped vessel walls do not get jammed together.

  • the said circular portion has a threaded region around the circumference.
  • the said circular portion with a threaded region thereby forms a mouth 1001 that allows the access for the fixing of a small lid once the mouth 1001 of the main lid 1 is opened.
  • a container 2 of the present invention has a side wall 13 with an open top forming a U-shapcd channel.
  • the U-shapcd channel 29 has a long outer wall 24, a top end portion of the outer wall 24 that has an outwardly extended rib 25 and a bottom end portion of the outer wall 24 that has a slanted T-shaped hinge 26, thus forming a U-shapcd opening 27, between the said outer wail 24 and the said slanted T-shaped hinge 26.
  • the said slanted T-shaped hinge 26 has a slit 28 forming the U-shapcd opening 27.
  • the sidcwalls 13 of the container 2 may include an integral reinforcing web 222 with an increased wall thickness on the inside of the container 2 compared to the adjacent non-webbed portions, for providing structural support to the sidcwalls 13.
  • the reinforcing web strengthens the sidcwalls 13 of the container and thereby improves the strength-to-material and/or strcngth-to-wcight ratios of the entire container.
  • the reinforcing web improves the container's resistance to collapse due to the buckling and stacking forces (compression loads imposed generally vertically downwardly due to stacking) of the sidewall that occur when the container is filled with a product or stacked with heavy objects, such as other containers.
  • the thinner walls of the container of the present invention have the ability to carry greater loads with the web-reinforced containers of the present invention possessing the ability to achieve performance characteristics that arc generally achieved by non-webbed containers by using more material and having more total weight.
  • the web- reinforced containers of the present invention may help containers absorb energy impacts (such as from being dropped or otherwise impacted), functioning as a spring to allow slight deformation without failure, and may even rebound or spring back to the original desired shape of the container.
  • the channel shapes of the reinforcing web may be arranged in a specific pattern.
  • the pattern may be any pattern that provides the desired benefits.
  • the various patterns that may be considered include but not limited to circles, ovals, arches, rectangles, hexagons, honeycombs, triangles, other sizes and shapes of diamonds, combination of diamonds and vertical bars; sharp or smooth patterns or elements, a mix of various patterns, mixed sizes of the size or different shapes, spaces irregularities within an otherwise regular pattern, or may even be somewhat random.
  • the selection of the reinforcing web pattern design can be especially helpful and important in improving the performance characteristics against forces in a downwardly projecting direction.
  • the sidcwalls of the containers of the present invention may be designed to be bowed outwardly, that is away from the container interior.
  • the said bowed sidcwall may have an outwardly arced or curved shape in the horizontal cross-section or may include a wide variety of cross-sectional shapes besides a smooth concave outward arcs, curves or straight lines. Bowing the sidewalls outwardly helps ensure that the compressive loads imposed upon the container force the sidcwall outward and thereby render the advantage of hoop strength to the sidewall.
  • the containers with straight sidewalls i.e. the centre has the same width as the comer
  • the containers including bowed sidcwalls better resist collapse from stacking forces (compression loads imposed substantially vertically downwardly due to stacking of other filled containers or otherwise). Additional strengthening of the containers is provided by forming bowed sidewalls in combination with the web patterns.
  • the said bowed portions may be located between corners.
  • the sidewalls ! 3 may be tapered so that the top opening formed by the upper edge is larger than the base of the container. In other words, the width of the container from one sidewall to its opposite sidewall at the top is wider than the width at the bottom. Tapered sidewalls enable nesting of one container with another. Nesting facilitates manufacturing, handling and storage of containers in an unfilled state. It is important to provide containers with a good nest-ability so that the volume required prior to filling or usage is reduced. Additionally, tapering can be such that an arced or curved sidewall shape (i.e. outwardly bowed sidewalls) is generally continuous in cross-section for substantially the entire height of the sidewalls.
  • the radius of the ares or curves at the bottom of the container sidewalls would be smaller than the radius of the arcs or curves at the top of the container sidewalls.
  • the tapering of the sidewalls can impact the ability of any given comer design to maintain the desired strength (viz.. increased corner thickness) and to maintain sufficient spacing between the nested containers.
  • the secondary lock 11 penetrates through the slit 28 into the opening 27 of the container 2, to attain the locked position. Once the secondary lock 11 gets locked into the slanted T-shaped spring-back hinges 26, it cannot be de-locked. As the said secondary lock 11 gets interlocked with the container's 2 slanted T- shaped spring-back hinges 26, to open the lid 1, the tear band 6 should be separated from the said lid 1, by peeling off the tear band 6 alt around the lid 1 using the knob 6a. After peeling off and removing the said tear band 6 from the lid 1, the said secondary section 8 of the lid, remains as a lock to the container 2 which acts as tamper-evidence.
  • a finger gripper 10 is provided to lift the lid 1 off the container 2 to detach from the primary lock 7.
  • the lid i and pail or container 2 are locked by a depending primary lock 9 with a radially inwardly extending protrusion 99 that cooperates with the radially outwardly extending lip 30 associated with the top or open end of the side wall 13 of the pail or container 2.
  • the container 2 is provided with a handle 101 of Fig. 5, made of a metal, for holding and lifting purposes.
  • the container 2 also provides with a handle portion 102 placed diagonal to the container 2 which rests on the container's side wall 13.
  • the side wall 13 of the container 2 is provided with a slot 50 (Fig. 6) that has a provision for the plastic handle 102 to rest and slide to the other end of the slot 50 to have access to the handle 102 that allows an user to hold and pour the content during regular use.
  • the curved wavy profiles 3 un the lid I are precociously designed to minimise the warpagc.
  • the container 2 has a plurality of internal stacking ribs 555 at the bottom around the corners on the inner surface for stacking or nesting the empty containers.
