Abstract
Abstract A safety cap and container combination is provided wherein the container mouth includes a plurality of spaced ribs or flanges each having a differently located notched-out passageway over which a cap member having at least one projecting internal lug is positioned in a single movement to close the container. In one form of the invention, a bead at the rim of the container mouth may be provided to mate with an internal groove in the cap member to seal tightly the cap member to the container. In order to remove the cap member, the cap member is moved partially away from the container to disengage the bead from the groove, and the lug member is then positioned and aligned with each slot and advanced therethrough in successive fashion to open the mouth of the container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
239 words
A safety lid and container combination comprising a cap member having a top portion and a depending peripherally continuous wall portion, the cap being flexible, the wall portion having an interior surface, the interior surface having at least one radially inwardly projecting lug thereon, the container having a mouth portion, the mouth having at least one outwardly projecting rib adjacent an upper end thereof, the rib being substantially continuous with a slot formed in one part thereof, the lug extending inwardly from the side wall a distance substantially equal to the thickness of the side wall, the lug having a substantially planar upper surface and an angled lower surface, the lug being at the lower end of the depending wall portion, the rib having a substantially planar lower surface and an angled upper surface, the interior surface having radially inwardly projecting means at a location angularly offset from the lug, the lug and the inwardly projecting means being of limited annular extent and contained within a separate semi-circular span of the interior surface, the angled surfaces of the lug and rib allowing the lug and rib to frictionally slide past each other in placement of the cap on the container in any position due to the flexibility of the cap, the substantially planar surfaces and thickness of the lug preventing removal of the cap from the container except when the lug is positioned adjacent the slot in the rib.
Claim 2
Dependent Claim
239 words
A safety lid and container combination comprising a cap member having a top portion and a depending peripherally continuous wall portion, the cap being flexible, the wall portion having an interior surface, the interior surface having at least one radially inwardly projecting lug thereon, the container having a mouth portion, the mouth having at least one outwardly projecting rib adjacent an upper end thereof, the rib being substantially continuous with a slot formed in one part thereof, the lug extending inwardly from the side wall a distance substantially equal to the thickness of the side wall, the lug having a substantially planar upper surface and an angled lower surface, the lug being at the lower end of the depending wall portion, the rib having a substantially planar lower surface and an angled upper surface, the interior surface having radially inwardly projecting means at a location angularly offset from the lug, the lug and the inwardly projecting means being of limited annular extent and contained within a separate semi-circular span of the interior surface, the angled surfaces of the lug and rib allowing the lug and rib to frictionally slide past each other in placement of the cap on the container in any position due to the flexibility of the cap, the substantially planar surfaces and thickness of the lug preventing removal of the cap from the container except when the lug is positioned adjacent the slot in the rib.
Claim 3
Dependent Claim
100 words
The safety lid and container combination as set forth in claim 1, wherein the rib extends outwardly from the mouth portion a distance substantially equal to the thickness of the mouth portion, the lug and the rib being of substantially the same size, the sizes of the lug and rib together with the angled surfaces thereof allowing the lug to slide over the rib at any point of contact therewith on pressure upon the cap to close the container but preventing removal of the cap from the container except when the lug is positioned adjacent the slot in the rib.
Claim 4
Dependent Claim
43 words
The combination in accordance with claim 1 wherein the bottom rib of said mouth portion below the rib is askew or on the incline so as to provide a screw-type, fluid-type closure between said cap member and mouth portion of said container member.
Claim 5
Dependent Claim
62 words
The combination in accordance with claim 1, wherein one of said cap and container members includes a bead and the other one of said cap and container members includes a groove for receiving releasably said bead to seal said cap member to said mouth portion of said container member when said cap member and said container member are in their closed position.
Claim 6
Dependent Claim
31 words
The combination in accordance with claim 4, wherein said bead is on said mouth portion of said container member, said groove being disposed in said interior surface of said cap mEmber.
Claim 7
Dependent Claim
24 words
The combination in accordance with claim 4, wherein said bead and said groove are annular in shape and are complementary shaped in cross section.
Claim 8
Dependent Claim
51 words
The combination in accordance with claim 4, wherein said bead is in the form of a screw thread, said groove being complementary shaped in cross section relative to the cross sectional shape of said bead to enable said cap member to be threaded onto said mouth portion of said container member.
Claim 9
Dependent Claim
165 words
A safety cap member for use with a container member wherein the mouth portion thereof comprises a plurality of spaced ribs, each of said ribs having an outwardly flared surface and each being provided with at least one slot, each slot being spaced in its respective rib differently form the next immediately adjacent rib, said cap member being cup-shaped and comprising top and depending walls and the interior surface thereof carrying at least one projecting lug adapted to frictionally slide over said ribs onto the container member in the closed position but being retained for movement in the opposite direction unless said at least one lug is aligned with said at least one slot and is advanced in step-wise fashion from the lowermost rib through the uppermost rib and one of said cap and container members includes a bead and the other one of said cap and container members includes a groove to receive said bead for sealing said cap member to said container member.
Claim 10
Dependent Claim
165 words
A safety cap member for use with a container member wherein the mouth portion thereof comprises a plurality of spaced ribs, each of said ribs having an outwardly flared surface and each being provided with at least one slot, each slot being spaced in its respective rib differently form the next immediately adjacent rib, said cap member being cup-shaped and comprising top and depending walls and the interior surface thereof carrying at least one projecting lug adapted to frictionally slide over said ribs onto the container member in the closed position but being retained for movement in the opposite direction unless said at least one lug is aligned with said at least one slot and is advanced in step-wise fashion from the lowermost rib through the uppermost rib and one of said cap and container members includes a bead and the other one of said cap and container members includes a groove to receive said bead for sealing said cap member to said container member.
Claim 11
Dependent Claim
109 words
The combination in accordance with claim 8, wherein said ribs are axially spaced apart defining spaced channels alternate along said mouth portion, said lug being disposed at the rim of said depending portion of said cap member, said channel disposed farthermost from the opening to said mouth portion of said container member being adapted to loosely receive said lug when said cap member and said container member are in their closed position and being sufficiently wide to enable said lug member to remain retained therein when said bead is moved out of said groove as a preliminary operation to the removal of said cap member from said container member.
Claim 12
Dependent Claim
31 words
The safety cap in accordance with claim 8, wherein said cap member is composed of flexible plastic material, said lug is integrally molded at the rim portion of said depending wall.
