CONTAINERS HAVING CAPS PERMITTING PRES E EQUALIZATION OF CONT Filed March ENTS OF CONTAINE FIG.3.
Flea.
w w v INVENTOR GEOBRYGE S. LEPORE H IS ATTORN EYS United States Patent CONTAINERS HAVING CAPS PERMITTING PRESSURE EQUALIZATION OF CONTENTS OF CONTAINER George S. Lepore, Clifiside Park, N.J., assignor to Lever Brothers Company, New York, N.Y., a corporation of Mame Filed Mar. 24, 1961, Ser. No. 98,255 4 Claims. (Cl. 21556) This invention relates to improvements in containers or receptacles formed of resilient plastic materials such as polyethylene, propylene and the like, for receiving liquids such as liquid detergents, cosmetics and the like, and it relates particularly to plastic bottles for receiving such liquid compositions and the closures therefor.
' Resilient plastic containers or receptacles, such as bottles having resilient walls, frequently are filled with materials at relatively high temperatures and are stored at considerably lower temperatures or may be subjected to varying atmospheric conditions which create a substantial pressure differential between the interior of the container and atmosphere. When, for example, the pressure within the container drops substantially below atmospheric pressure, a flexible container tends to collapse or at least change in shape. Likewise, if the pressure inside the container exceeds atmospheric pressure, the container may bulge and because of the increased pressure therein, may leak.
The present invention relates to an improved form of closure for resilient containers or containers having resilient walls to enable the container to breathe under changing pressure conditions to equalize the pressures inside and outside the containers without allowing leakage of the contents of the container.
More particularly, the closure for the container is provided with one or more grooves which connect the interior of the container to the atmosphere thereby permitting air or other gas to flow from the exterior of the container into the container or vice versa, the groove or grooves, however, being of such dimensions that leakage of the liquid contents of the container is prevented even when the container is disposed with the closure below the level of the liquid in the container.
It has been found that the dimensions of the groove or grooves to achieve the desired results are quite critical and should not exceed about .003 of an inch in depth or be less than about .002 of an inch deep. The width of the groove is less critical but for best results it should not exceed about .005 of an inch or be less than about .002 of an inch.
For a better understanding of the present invention, reference may be had to the accompanying drawings in which:
FIGURE 1 is a perspective view of a typical flexible plastic bottle having a cap thereon of the type embodying the present invention.
FIGURE 2 is a view in cross-section through the cap and neck of the bottle; and
FIGURE 3 is a bottom plan view of the cap removed from the bottle.
As shown in FIGURE 1, the bottle may be of substantially any desired shape suitable for storing and vending a liquid material, such as a detergent, a hand lotion or the like. It preferably is formed of a resilient plastic, such as, for example, polyethylene or polypropylene or other similar, relatively inert, flexible plastic material. The bottle 10 is provided with a threaded neck 11 for receiving an internally-threaded closure cap 12 which may be formed of material similar to the container or a more rigid material, such as polystyrene, phenol-formaldehyde resin, or the like.
Referring to FIGURE 2 of the drawings, it will be seen that the skirt 13 of the cap 12 has internal threads 14 for engagement with the threads 15 on the neck 11 of the bottle and is also provided with a centrally-located plug 16 of solid or hollow formation which engages in the pouring opening in the neck of the bottle to close and seal it. Also, the cap 12 has a transversely-extending, generally annular inner surface 17 which engages the end of the neck 11 of the bottle when the cap is screwed fully on the neck. With the arrangement described, if the bottle is subjected to diiferent external and internal pressures, the bottle would tend to collapse partially or to expand partially.
In accordance with the present invention, the cap 12 is modified to permit the bottle to breathe so that the pressures inside and outside of it are equalized. To that end, the cap 12 has one or more grooves 13 formed in it extending lengthwise of the plug 16 and across the annular extending portion 17 so that the interior of the bottle is connected to the exterior atmosphere. In the cap illustrated, three grooves 18 are provided. Air can flow freely between the outside of the neck 11 and the skirt 13 of the closure cap to the outer end of the groove or grooves 18, for the reason that the skirt and neck are spaced slightly apart and a helical passage exists between the turns of the threads on the neck and cap. While axially and radially arranged grooves 18 are illustrated, they can be arranged tangentially or at any other angle across the laterally-extending surface 17 of the cap and spirally around the plug 16, or in any other desired way. Moreover, more or fewer than three grooves may be provided.
A critical feature of the invention is the depth of the groove or grooves 18. The grooves are shown in exaggerated size in FIGURES 2 and 3, but it has been determined that the grooves should not exceed .003 of an inch in depth and should not be less than .002 of an inch in depth in order to permit flow of gas or air along the grooves between the outside and the inside of the bottle, and, at the same time, prevent the liquid contents of the bottle from leaking when difierential pressures exist between the interior and exterior of the bottle and the bottle is disposed so that the pouring opening is below the level of the liquid contents of the bottle. Tests have demonstrated that bottles of the kind embodying the invention as described herein can be filled with liquid having a temperature of F. and then chilled to 40 F. without causing them to collapse. Even when the bottles are stored in an inverted condition, leakage of the liquid is completely prevented. When the depth of the grooves is increased to .005 of an inch, leakage occurs. When the depth of the grooves is decreased below .002 of an inch, the bottles do not leak but they tend to collapse when their contents are cooled from 100 F. to 40 F.
The width of the groove or grooves 18 is preferably on the order of .005 of an inch, but the width of the grooves may, if desired, correspond to the depth of the grooves so that a groove having a depth of .002 of an inch may also have the same width. Liquid does not leak from the bottle when the cap is provided with grooves 18 .0025 of an inch deep and .005 of an inch wide. Depending upon the viscosity of the liquid packaged in the container, some variation in the dimensions of the grooves is possible. With more viscous liquids, the groove sizes can be increased and with less viscous materials, the groove dimensions should be decreased. However, for liquids such as concentrated detergents used for dishwashing or laundering, a depth of .002 to .003 of an inch is satisfactory. The widths of the grooves do not appear to be as critical as their depth, possibly for the reason that the cap compresses slightly when it is screwed onto the container thereby decreasing the dimensions of the groove and keeping the dimensions of the groove within a critical range.
It will be understood that the invention is susceptible to modification. Thus, if the neck of the bottle can be molded with precision to include grooves of the dimensions indicated above, the lip and internal surface of the neck may be grooved rather than the opposing surfaces of the closure cap. Moreover, when the cap does not include a plug 16, the grooves may be formed in the surface or surfaces of the closure cap which engages the neck of the bottle to etfeet a seal therewith.
Accordingly, the form of the invention illustrated herein should not be considered as limiting and the invention should be considered as limiting only by the terms of the following claims.
I claim:
