ATTORNE YS 3,175,741 (ILUSURE AND DldPENdING CAP EUR TlllE NEEK DI A CQNTAINER Alvin 3!. Porter, Excelsior, Minn, assignor to Product Design & Engineering, Inc, Minneapolis, Minn. Filed Mar. 12, 1964,51. No. 351,359 '7 tllairns. (El. 222 521) The invention relates to an improvement in a cap for a container, the cap allowing closure of the container and also dispensing of material therefrom.
It is an object to provide a cap having a base portion with an overcap portion threadedly engaged thereto, the overcap portion carrying a lug adapted to bypass stop means within the base portion which is yieldable in the direction the overcap portion is rotated to threadedly engage the same on the base, the stop means having a construction for engagement with the lug which prevents removal of the overcap portion when the same is rotated in the opposite direction for dispensing the construction allowing easy assembly of the cap and a maintaining of the overcap portion captive on the base portion.
It will not be here attempted to set forth and indicate all of the various objects and advantages incident to the invention, but other objects and advantages will be referred to in or else will become apparent from that which follows.
The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings, showing by way of example a preferred embodiment of the inventive idea wherein like numerals refer to like parts throughout.
In the drawings forming part of this application:
FIGURE 1 is a perspective view of the cap in position on a container with the overcap portion in captive position on the base portion, a portion of the container being broken away.
FIGURE 2 is a section on the line 2--2 of FIGURE 1 showing the cap in a closed position.
FIGURE 3 is a section similar to FlGURE 2 with the cap in an open position.
FIGURE 4 is a section on the line 44 of FIGURE 3.
FIGURE 5 is a vertical section through the overcap portion removed from the base portion.
FIGURE 6 is a bottom plan view of the overcap portion.
FIGURE 7 is a top plan view of the base portion.
FIGURE 8 is a perspective view of the cap mounted on a container, portions of the cap and container being broken away.
Referring to the drawings in detail, the cap A includes the base portion It) which is connected to the neck 12 of a container B. The base portion ltl includes the outer hollow cylindrical portion l4 having formed on the outer surface thereof the threads 16. Extending inwardly of the lower end of the cylindrical portion :14 and normal to the longitudinal axis thereof is the narrow annular wall portion 18 which terminates at its inner edge in the inner axial hollow nozzle 29 thereby forming a first annular channel 159 between the portion I4 and the nozzle 29. The upper end of the nozzle 29 is formed with the transverse bar portion 22 which bisects the upper open end of the nozzle thereby forming fiow passages 17 and 21. The bar portion includes the upper inverted ii-shaped portion 24 which terminates at its apex in the axial closure tip 26.
Further provided are the spaced stops 2% and 3% which are yieldable, for the same are formed of plastic. The stops may be formed of other resilient material or construction. The stop 28 is formed on the outer surface of the nozzle 2t and extends upwardly from the wall portion 18. The stop 28 includes the inclined ramp poreion 32 ddlhfldl Patented Mar. 30, 1965 which terminates at its greatest thickness in the shoulder stop edge 34. The companion stop is formed on the inner surface of the outer cylindrical portion 14 extending upwardly from the wall portion 18 in juxtaposition to stop 23. The stop 30 includes the inclined ramp portion 36 which terminates at its greatest thickness or rise in the shoulder stop edge 33.
The numeral 4% designates an overcap including the outer cylindrical wall portion 42 which forms an annular apron and which terminates at the upper edge thereof in the circular top portion 44 having the concave formation 45 and the axial outlet hole 48.
Depending from the top portion 44 is the inner cylindrical wall 53 concentric with and spaced from the outer wall 42, and formed on the inner surface of the inner wall are the threads 52 which are engaged with the threads 1'5 of the portion 14- of the base portion 10 as hereinafter described:
Also depending. from the top portion 4-4- is the collar portion 54 which is spaced inwardly of the inner Wall 59 and concentric thereof thereby forming an annular channel 51 between the wall 5%) and collar 54. The outer diameter of the collar 54 is substantially equal to the inner diameter of the outer cylindrical portion 14 of the base 10. The inner diameter of the collar 54 is substantially equal to the outer diameter of the hollow nozzle 20 whereby the collar 54 fits snugly in the annular channel 21 to make a sealing engagement between collar 54, nozzle 2% and cylindrical portion 14 but free enough to allow rotation of the collar in the channel as hereinafter described. The depth of the collar 54 and the upper extent of the nozzle 25b is such that the collar remains in contact with the nozzle 2% at all times even in the raised or open position of the overcap 40 upon the base as will be seen particularly in FIGURE 3.
The collar 54 terminates at its inner upper end in the truncated bone formation 55 which terminates in the outlet hole 43. Extending downwardly from the lower edge of the collar 54 and into the channel 21 is the extension as in the form of an arcuate lug which is tapered to its forward end 58. The width of the lug 56 at its rear or base end 60 is greater than the distance between stops 28 and 3d at the greatest thickness thereof. The tapered forward end of the lug as aids in entry of the lug between the stops 2d and 3t and forced passage therebetween.
The cap is assem led and operated in the following manner: The overcap did is positioned on and in axial alignment with the base It with the lug 56 extending partially into the channel 19. The overcap is then rotated whereby the threads 52 of the overcap engage the threads 16 of the base portion In. As the overcap is rotated clockwise and the threads progressively engage the overcap, the same is, of course, drawn down upon the base it and as it progresses the lug 56 comes to the stops 28 and 30. With further rotation of the overcap the lug 56 is forced through the restricted passageway between the stops to a point past the stops. The stops 28 and 30 are yieldable as is the lug, inasmuch as the same are plastic and the portions on which the same are mounted are plastic.
With the lug 5d forced to a point just beyond the stops 28 and 30, as illustrated particularly in FIGURE 4, the overcap cannot be rotated from that point in an opposite or counterclockwise direction due to the base end at) of the lug contacting the stop edge and 38 of the stops 28 and 30. The overcap is now captive upon the base portion 19, and in this position the overcap is not screwed down fully upon the base whereby the closure pin 26 is not within the outlet hole 48 thus leaving the cap in an open position whereby the contents of the container B may tiow through the core 2%, the passages 19 and 21', and outlet hole 48. The cap is closed by rotating the overcap 4b in a clockwise direction whereby the same is drawn down further upon the base It by the threads provided and the closure tip as enters the outlet hole lb. Again, the cap is placed in an open position by rotating the overcap 4t counterclockwise until the lug 56 strikes the stops 28 and 3t? and as a result the tip 26 is withdrawn from the outlet hole 48. The lower extent of the lug 56 is such that the lower edge thereof does not contact the wall 18 when the cap is in the closed position nor does it escape the stops 238 and 39 when in the upper open position.
The invention is not to be understood as restricted to the details set forth since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.
