The inner skirt is engaged within the container neck to form a first seal. A plurality of concentric members depend from the container cap and engage the top of the container neck to form a second seal An integral annular sealing ring is positioned between the intermediate skirt and the con' tainer to form a third seal.
2 Claims. 4 Drawing Figures I CHILD-RESISTANT CLOSURE BACKGROUND OF THE INVENTION Closures which are utilized for liquids have been a problem in the art. These closures generally comprise a container and a cap wherein, for example, the cap is threaded onto the container neck. When plastic cups are utilized, there is a tendency for the cap to take a set after being initially placed on the container. When this occurs, leakage often results unless the cap is mounted on the container with ever-increasing torque. Various methods have been used in the past to eliminate leakage. The most common prior art structure is to place a cork or another type insert in the upper part of the cap. When the cap is placed on the container, the cork engaged the neck and tended to prevent leakage.
Another problem with many prior art caps is that, particularly with plastic caps, there is a tendency for the cap to back off after its initial placement on the container. Again, this often results in leakage.
SUMMARY OF THE INVENTION The present invention relates to a closure which is particularly adapted for holding liquids. The closure includes a container having a bottom, a sidewall, a neck and an annular shoulder extending between the neck and the sidewall. A cap having atop and an outer skirt is threadably engaged on the container neck. The cap also includes an inner skirt which extends downwardly into the neck forming a first liquid seal when the cap is positioned on the container. An intermediate skirt is positioned between the outer skirt and the inner skirt. A sealing ring is positioned between a lower surface of the intermediate skirt and a portion of the container. The annular ring serves as an O-ring" and functions as a second sealing means. Additional means. for example a plurality of concentric rings, depend downwardly between the inner skirt and the intermediate skirt. When the cap is in closed position on the container, the depending rings engage the upper surface of the container neck and serve as a third sealing means.
BRIEF DESCRIPTION OF THF DRAWINGS FIG. I is a fragmentary, side elevational view, show ing a closure according to the present invention. The cap is shown elevated from the container;
FIG. 2 is a sectional view taken along the line 2-2 of FIG. 1;
FIG. 3 is a sectional view taken along the line 3-3 of FIG. 1; and
FIG. 4 is a fragmentary, sectional view. similar to FIG. 1. showing the cap in closed and sealing relationship with the container.
DESCRIPTION OF THE PREFERRED EMBODIMENTS A closure according to the prcsent invention is gener ally indicated in the drawings by the reference number l0. The closure includes a container ll having a bottom 12, a side all 13, a threaded neck I4 and an annular shoulder I5 extending betueen the neck 14 and the sidewall I3. In the present embodiment, the shoulder 15 is stcppcd and includes an upper portion 16 and a lowcr portion 17 [see FIG. 4). The neck 14 includes an inner face I8.
The closure 10 also includes a cap 20 having a top 21 and an outer skirt 22. Spaced concentrically with respect to the outer skirt 22 is an inner skirt 23 of a shorter length than the outer skirt 22. The inner skirt 23 fits within the neck 14 of the closure 10 and engages the inner face 18, when the cap is in its closed position. The engaging relationship between the inner skirt 23 and the face 18 of the neck I4 provides a first sealing means which tends to prevent leakage of material from within the container II.
An intermediate skirt 24 depends from the top 2! and is concentrically located between the outer skirt 22 and the inner skirt 23. The intermediate skirt 24 includes a lower end 25 having an interior surface 26. One or more interference rings or annular sealing rings 27 are positioned between the interior surface 26 of the intermediate skirt 24 and the upper portion 16 of the annular shoulder I5. In the present embodiment. the annular sealing rings 27 are integral with the container I l and act as O-rings. The annular sealing rings 27 both seal the escape of material from within the container I1 and also provide friction forces which tend to prevent the cap 20 from backing off the container 1].
Referring to FIG. 4, a plurality of concentric rings 28, 29 and 30 depend from the top 21 of the cap 20 and are located between the intermediate skirt 24 and the inner skirt 23 of the cap 20. The concentric rings 28-30 are semi-flexible in nature and are ofa length such that when the cap 20 is in its closed position on the container 11, lower edges 31 of the rings 2830 engage and are compressed by a top surface 33 of the container neck 14. This functions as a sealing means to prevent leakage from the container II.
In the present embodiment, the cap 20 has a pair of opposed downwardly extending lugs 34 formed on the bottom edge of the outer skirt 22. Complementary lug recesses 35 are provided in the shoulder 15 of the container l]. Camming surfaces 36 are provided adjacent the lug recesses 35. To assemble the cap 21 on the container 11, the cap is applied to the upper end of the container II and rotated in a clockwise direction. Continued rotation causes the lugs 34 to engage the camming surfaces 36 which spreads the lugs 34 and leads them to the lug recesses 35. When this occurs, the lugs 34 snap into the lug recesses 35 and the cap 20 is retained on the container II until the lugs 34 are removed from the lug recesses 35. To remove the cap 20, the sides of the cap opposed from the lugs 34 are squeezed. The cap 20 is constructed of a semi-flexible material and the squeezing deforms the cap to an oval configuration so that the lugs 34 are moved out of the lug recesses 35. The cap 20 then can be rotated in a counterclockwise direction to remove the cap 20 from the threaded neck 14 in the normal manner.
Various other modifications of the above-described preferred embodiments will be apparent to those skilled in the art and may be made without departing from the spirit and scope of the appended claims.
