Definitions
- Applicant has invented a paint can and lid of molded plastic material with an interengaging structure which fastens the lid on the can to seal the can and to withstand the shocks of handling and transporting the cans of paint.
- This fastener structure which is molded into the can and lid, acts to exert pressure between the lid and can to seal the can, and is readily engaged and disengaged to apply and remove the lid as necessary.
- Plastic materials suitable for the present invention are thermoplastic resins which can be processed by injection molding.
- a preferred material for this structure would be high density polyethylene because of its memory, flexibility and resistance to certain chemicals such as acids and alkalis.
- These plastics also include polypropylene, ethylene-vinyl acetate copolymers, propylene-modified polyethylene, acetals, acrylonitrile-butadiene-styrene, polystyrene blends, chlorinated polyesther, fluoro chemicals, polyamides, vinyls, and polyvinylidene chloride.
- These resins can have fibrous reinforcement which gives greater impact, tensile and flexural strength.
- the choice of the materials and fillers used must satisfy the requirements that they have the necessary reilience or pliability for the action of the fasteners.
- the two complementary series of elements one projecting axially upwardly on the wall of the container, the other downwardly on the lid, interengage when the cover is pressed down, the elements having their head portions wider than their base portions, so that when interengaged, they may not be separated without stressing or distorting the material.
- the material is sufficiently -resilient or pliable that, when elements in the peripheral rows are engaged successively, the last ones may be pressed into interengagement as a result of the resilience or pliability of the peripheral series of elements. These elements will then resist separation by force applied to the lid.
- an object of the invention to provide a fastener structure which fastens the lid on a can to seal the can and to withstand the shocks of handling and transporting the cans of paint.
- the fastener structure comprises two continuous series of similar, complementary, interdigitating elements with spaces between the elements which are complementary to the elements each of said two series of elements being formed integrally with and supported by the can and the lid, resp., and it is characterized in that the can and the lid have peripheral contacting surfaces, and that each of the elements has inclined laterially, engaging surfaces to exert a transverse force on the can and its lid pressing said peripheral contacting surfaces together to provide a seal between the can and the lid.
- the lid and the can are formed with peripheral contacting surfaces to seal the can.
- the can is provided with an inclined internal surface on its wall and the lid has a peripheral flange extending downwardly, so that when the lid is pressed down, the flange on the lid will be wedged into the inclined surface on the wall.
- the interengaging elements are provided with transversely inclined surfaces which interengage to produce a radial or lateral force between the can and lid, so that such force exerts pressure between engaging walls on the lid and can, thereby providing a tighter seal.
- the enlarged, intercalated heads of the elements have axially inclined sides which exert axial pressure to maintain engagement and to seal contacting peripheral transverse surfaces.
- peripheral fastener structure shown for fastening the cover on a can may be used wherever a peripheral interengaging fastener is required.
- two plastic tubes may be connected by a similar annular fastener structure.
- Fasteners of this type may also be used as two interengaging linear rows, each row being adjacent a wall engageable with a wall adjacent the other row of elements, so that the lateral wedging action of the laterally inclined surfaces of the elements will provide a sealing contact between the two walls.
- An additional feature is the provision of an interlocking engagement for cans on a shelf.
- the lid 2 of the can 1 has a peripheral downwardly opening channel 3 which receives the upper edge of the wall 5 of the can, as shown in Figure 2.
- the outer wall 12 of the channel in the lid fits over the outer wall of the can body, and the inner wall 13 has a downwardly extending flange 14 which is forced down within an inclined surface 15 on the can body, so that the flange 14 is in effect wedged into sealing contact with the wall of the can.
- the two series of interengaging elements are formed with one series of upstanding elements 11 on the wall 5 of the can body and the other series of downwardly extending elements 10 in the channel 3 of the lid.
- the elements 10 on the wall are each formed with a head portion 20 of greater thickness peripherally than the base portion 21 to leave larger spaces between the base portions 21 of the wall elements, with the heads 20 of the wall elements fitting between the base portions than between the head portions.
- the elements 10 in the channel of the lid are complementary to the first series, so that the head portions 22 of the lid elements may fit between the base portions 21 of the wall elements, with the heads 20 of the wall elements fitting between the base portions 23 of the lid elements and the sloping sides of the elements of the two series engaging to increase the axial pressure between the lid and can.
- These elements 10 and 11 further have transversely inclined engaging surfaces as shown in plan views Figures 5 and 6.
- the elements 11 on the can body taper radially outwardly with inclined surfaces 24, 25, while the elements on the lid taper radially inwardly with inclined surfaces 26, 27, so that the two series of elements are wedged apart radially when the elements are engaged by pressing the lid onto the can.
- the lid is applied to the can by starting at one side (see Figure 7) to engage the fastener elements 10 on the lid between elements 11 on the wall of the can.
- the elements of both series are sufficiently pliable and elastic to be flexed as they successively interengage about the periphery, until the final closing elements are reached, as shown in Figure 4. These may then be engaged by strong downward pressure, the peripheral series of elements and the material of the can and lid being sufficiently pliable and resilient to allow the final elements to interengage.
- the head portions are slightly spaced from the opposite valleys at 28, so that the pressure on the lid is arrested by engagement of peripheral contacting surfaces such those of the channel on the lid with the top edge 29 of the wall flange 30.
- the head portions 20 of elements 11 on the wall are also slightly spaced laterally from the wall body by the spaces 31 to allow greater flexure of these elements.
- the valleys between the elements on the wall have drains 32 at the bottom to allow any liquid to drain off from between the elements.
- the outer side of the wall is provided with a circumferential rib 33 below its top edge to be engaged by the flange 12 on the lid.
- a notch 34 allows insertion of a prying tool to remove the lid. Upon force concentrated at one point, the interengaged elements at that point may be separated, the flexibility of the peripheral elements allowing separation of one of two elements.
- the lid also has a circumferential groove or fold 35 inwardly of the fastener formation to provide greater resilience and . flexibility of the lid.
- the groove 36 adjacent the edge of the lid provides for stacking the cans by engaging a bead 37 on a can above.
- the rim formations on the wall 40 and lid 42 are modified as shown in Figure 8.
- the series of fastener elements on the wall are formed on its inner side, as in the first form, but the wall is formed with a peripheral bead on its outer side, as at 41.
- the lid 42 also has fastener elements 10 to engage those on the wall, but the peripherally extending wall above the fastener elements has a bead 43, which is spaced from the bead 41 on the wall when the lid is fastened on the can. This space allows a prying tool to be inserted between the beads to pry off the lid.
- the fastener elements exert a radial force between the lid and can to maintain sealing engagement between the flange 14 on the lid and the wall surface 15 on the can.
- the projections of each rim have enlarged beads 51 which may fit into the spaces 52 between projections 51 on an adjacent can.
- the fastener structure of this invention embodies series of interengaging elements which exert a force laterally of the series of fasteners to secure tight, sealing engagement between the members connected by the fasteners and also tightly secure the members in the direction of engagement of the elements.
- the plastic elements may be engaged successively to secure the two elements against separation, yet may be readily separated by a force applied at one point.
