DESCRIPTION
STACKABLE CONTAINERS WITH REMOVABLE COVER MEMBERS TECHNICAL FIELD
This invention relates to a means for sealing and locking a container cover to an open mouth of a container, and more particularly, the present invention is directed to a cover having a locking and sealing device whereby the configuration of the cover and matching configuration of an associated container (e.g., having flat walls) are always secured in fixed alignment with each other when the cover is secured over the mouth of the container, and wherein the top of the cover is provided with an overall configuration that matches the bottom configuration of the container, whereby the container, whether rectangular or circular, is readily adapted to be received and stacked on a preceding covered container in a stable vertical formation. BACKGROUND ART
As is well known in the art various problems and difficulties are encountered in providing suitable means for securing a cover member to the open mouth of a container where the configuration of the container is not suitable or operably compatible with the cover member. That is, there is a need to provide a container cover member that is capable of being mounted to and over the open mouth of a noncircular container, wherein the cover is required to be rotated through a predetermined angle and wherein the cover will always be locked in place in alignment with the configuration of the container, allowing additional like containers to be readily stackable in a stable manner. The present problem is solved by a new and distinct cover member and a locking and sealing means that establishes a very positive closure between the cover and the container opening, particularly with respect to rigid and semi-rigid plastic containers that have either circular or rectangular cross-sectional configurations .
SUMMARY OF THE INVENTION
Accordingly, it is an important object of the present invention to provide a cover for sealing and locking the open mouth of a container, wherein at least two locking means defined by a pair of keeper channels are employed and oppositely disposed 180° from each other about the container collar that defines the opening or mouth of the container, and wherein the container cover includes a pair of matching or corresponding keeper members that are integrally formed 180* from each Dther on the peripheral inner wall of the cover, whereby the keeper members will lockingly engage within the respective keeper channels formed in the container collar. The 180° arrangement of the corresponding keeper channels and keeper members limits the rotational movement of the cover to a predetermined angle such as a single 90° turn. Another object of the present invention is to provide a container cover that is defined by a recessed receptacle which is formed to have a configuration which matches that of the container, whereby the bottom and side walls of the container form a corresponding configuration so that the container will be snugly received in the receptacle of the cover, and wherein the recessed cover portion is provided with a handle that is further recessed in the container cover. Once a container is mounted in its preceding container cover it can be seen that the additional stackable containers will remain in a vertical stable position with or without any contents being stored in the containers.
Still another object of the present invention is to provide a container and container cover of this character that is readily adaptable for use with containers having overall rectangular configurations, whereby the invention will permit the cover to be mounted over the open annular collar, wherein only a pair of the present keeper channels would be required. A container having a round body and a c matching rounc cover can be provided with at least two or
more keeper channels, whereby the circular configuration need not be restricted to its position relative to that of the container's configuration, because both the cover and container have identical circular configurations and will always be in matching relationship to each other. This, however, is not true when the container is formed having a rectangular configuration. More specifically, if a container is provided with a rectangular cross-sectional configuration and the cover is also formed having the identical rectangular configuration then the cover must be attached to or placed over the circular collar of the container so that the cover is offset, say 90°, from that of the oppositely disposed keeper channels, and then turned to close the container and align the cover with the container, as will be noted in the following detailed description of the invention.
The characteristics and advantages of the invention are further sufficiently referred to in connection with the accompanying drawings, which represents one embodiment. After considering this example, skilled persons will understand that variations may be made without departing from the principles disclosed; and we contemplate the employment of our structures, arrangements or modes of operation that are properly within the scope of the appended claims.

Referring to the drawing figures, there is illustrated in Figure 1 a perspective view of a covered container, generally indicated at 10, wherein a rectangular container 12 is shown having a matching rectangular cover member 14
secured to the container 12. Container 12 comprises a wall structure or body 15 having a pair of substantially flat elongated side walls 16, end walls 18 and a bottom wall 19 which is better illustrated in Figure 6 as being formed with a concave central portion 20, a generally annular flat portion 21 and a curved peripheral section 22 which joins the lower ends of the side and end walls. For illustrative purposes the side walls 16, end walls 18 and bottom wall 19 are integrally formed to define the interior compartment 24 in which various items can be readily stored. In the embodiment of Figures 1 through 6, the container is illustrated as comprising the rectangular body 15, wherein an opening 26 is defined by an annular collar 28 that protrudes upwardly from body 25 so as to further define the mouth of the container that is required to be covered a the cover member 30. See; Figure 6.
Cover member 30 is also formed with an upper peripheral edge 31 and a downwardly extending peripheral side and end walls 33 and 35, respectfully. Both the edge 31 and walls 33, 35 have a rectangular configuration to match the body of the container 12. To permit the cover member to lock onto the collar 28 and close the container while maintaining the side walls of the cover and container in alignment, there is provided a locking means, generally indicated at 32, which is integrally formed on the collar 28 of the container and a pair of cooperating keeper members 44 integrally formed on a generally circular inner cover ring 46 of the cover. See Figures 2-4. The locking means 32 of this embodiment includes a pair of keeper means 34 and 36. See Figures 4 and 5.
Each keeper means 34 and 36 comprises an inwardly projecting keeper rib member 38 which is formed integrally on the outer surface of the collar 28 of each container and forms a channel extending below the rib member for receiving the keeper members on the cover. As better illustrated in the
schematic view of Figure 5, keeper rib member 38 has an inclined section 39, a flat or slightly inclined section 40 and a depending stop arm 42 which is positioned to be engaged by one of the keeper members 44 as is illustrated in Figures 3, 4 and 5. The cover ring 46 includes generally semicircular sections 46a and 46b and a section 46c of each of the side walls 33 as is shown in Figure 3. In Figure 5, the keeper member 44 is schematically shown as being moved in a clockwise direction, as indicated by arrows 45, at first engaging the inclined section 39 of rib 38. The keeper member, depicted at positions 44a and 44b, is shown sliding under the rib 38 and along the flat or slightly inclined section 40 until fully engaged with a depending stop arm 42. In this position the side walls 33 and end walls 35 of the cover are aligned with the respective side and end walls of the container as is illustrated in Figure 6.
At this time the cover 14 has been fully rotated clockwise through a predetermined angle, e.g., 90°, from the entrance to the channel formed by rib 38 to the stop arm 42 at which point the cover member 14 is in a locked position and can not be removed until it is rotated in a counterclockwise direction.
The annular downwardly depending peripheral walls 33, 35 of the cover member 14 define a skirt generally indicated at 47 in Figure 6 for covering the neck of the container and providing a continuation of the side and end walls thereof. A shallow curved flange 48 (Fig. 1), which matches the curved end section 22 of the container bottom, is integrally formed with the skirt and extends upwardly from a generally annular flat portion 5C of the top wall of the cover. The annular flat portion 50 matches the flat portion 21 of the container bottom. The top wall of the cover member further defines a convex central portion 52 which matches the concave central portion 20 of the container bottom. A pair of finger recesses 54 are formed in the convex portion 52 whereby the
cover 14 can be conveniently rotated and removed from the container by a user. The top wall (portions 50 and 52) and the curved flange 48 define a receptacle 51 for receiving the bottom of a matching container. Referring now to the alternative embodiment which is illustrated in Figures 7 through 9, there is shown a pair of the identical circular or cylindrical stacked body members 61 and circular cover members 62. Cover 62 is similar to that described above having a receptacle or recess 64 defined in the top wall 66 thereof, which also includes a pair of finger recesses 65 for rotating the cover member. The receptacle 64 is adapted to receive the superposed container therein, as illustrated in Figure 8.
Figure 9 is a cross-sectional view taken along line 9-9, whereby the arrangement shows at least four equally spaced-apart keeper channels 68 about the annular collar 70 of the container. Since the cylindrical configuration of the containers 60 and matching cover members 62 are identical, the cover member can be attached and rotated about the annular collar without the restriction that prevails when the container and cover are both rectangular. Accordingly, for each keeper channel 68 the same number of keeper members 72 is required.
The containers are preferably molded of a clear plastic, e.g., TPE and the cover members are made of polypropylene.
The foregoing should only be considered as illustrative of the principles of the invention. Further, since numerous modifications and changes may readily occur to those skilled in the art, it is not desired to limit the invention to the Q exact construction and operation as shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the claimed invention.
