Definitions
- a one piece plastic molded cap comprising a top wall and peripheral skirt and having threads loosely suspended from the top wall and separated from the surrounding skirt so that the threads distort and resist unscrewing from a threaded engagement with a container neck when the unscrewing is attempted by application of simple torque to the top wall and skirt.
- the skirt is inwardly deformable and has means which lockingly engage the threads to prevent said distortion simultaneously with the application of said torque to enable unscrewing and removal of the cap.
- the cap may be molded of resilient material as a one piece integral structure in low cost quantity production by modern molding methods and comprise a cover portion and a helical or thread member.
- the cover portion has a top wall, peripheral skirt and inner concentric annular flange for sealingly engaging the interior of the bottle mouth.
- the helical member is relatively loosely suspended from the top wall concentric with and spaced between the skirt and flange to engage the exterior threads of the bottle neck and retains the top wall and flange in position to seal the bottle.

- the helical member by virtue of said relatively loose suspension, distorts when simple, unscrewing torque is applied to the cover by means of the skirt which may surround and conceal the helical member. This distortion serves to cause the helical member to more tightly grip the bottle neck and prevents unscrewing therefrom.
- the skirt in turn is pliable, permitting radially inward deformation of certain designated areas whereby interengagement of the skirt and helical member is effected to secure the parts for movement together and to prevent distortion of the helical member.
- the required finger pressure and coordination to unscrew the cap by simultaneous exertion of inward deformation and torque forces on the skirt will be impossible for small children to achieve.
- the skirt is substantially shortened permitting finger access to the helical member to which torque can be directly applied, the prominence and attractiveness of the cover portion as compared to the relative obscurity and the difiiculty of direct manipulation of the helical member by a childs fingers serving as the child-proof characteristic.

No. 655,535 Int. 'Cl. B65d 55/02, 41/52 US. Cl. 215-9 8 Claims ABSTRACT OF THE DISCLOSURE A one piece plastic molded cap comprising a top wall and peripheral skirt and having threads loosely suspended from the top wall and separated from the surrounding skirt so that the threads distort and resist unscrewing from a threaded engagement with a container neck when the unscrewing is attempted by application of simple torque to the top wall and skirt. The skirt is inwardly deformable and has means which lockingly engage the threads to prevent said distortion simultaneously with the application of said torque to enable unscrewing and removal of the cap.
Background of the invention Summary of the invention Among the objects of the invention is to provide a child-proof cap for bottles having threaded necks of conventional construction. The cap may be molded of resilient material as a one piece integral structure in low cost quantity production by modern molding methods and comprise a cover portion and a helical or thread member. The cover portion has a top wall, peripheral skirt and inner concentric annular flange for sealingly engaging the interior of the bottle mouth. The helical member is relatively loosely suspended from the top wall concentric with and spaced between the skirt and flange to engage the exterior threads of the bottle neck and retains the top wall and flange in position to seal the bottle. The child-proof characteristic of the cap is achieved by the action of the helical member with respect to the cover. The helical member, by virtue of said relatively loose suspension, distorts when simple, unscrewing torque is applied to the cover by means of the skirt which may surround and conceal the helical member. This distortion serves to cause the helical member to more tightly grip the bottle neck and prevents unscrewing therefrom. The skirt in turn is pliable, permitting radially inward deformation of certain designated areas whereby interengagement of the skirt and helical member is effected to secure the parts for movement together and to prevent distortion of the helical member. The required finger pressure and coordination to unscrew the cap by simultaneous exertion of inward deformation and torque forces on the skirt will be impossible for small children to achieve. In a simplified form of the invention the skirt is substantially shortened permitting finger access to the helical member to which torque can be directly applied, the prominence and attractiveness of the cover portion as compared to the relative obscurity and the difiiculty of direct manipulation of the helical member by a childs fingers serving as the child-proof characteristic. The cap is also corrosion resistant, sanitary for use on comestibles, practical and eflicient to a high degree in use.
Brief description of the drawing FIG. I is a bottom plan view of a child-proof cap constructed to embody the invention.
FIG. 2 is a vertical section of the cap taken substantially along line 2 2 in FIG. 1 but showing the cap mounted upright on a bottle neck.
FIG. 3 is a vertical section of the cap removed from the bottle taken along line 3-3 in FIG. 1.
FIG. 4 is a front elevational view of the cap mounted on a bottle neck with the skirt broken away to illustrate the action of the helical member, the broken line indicating the distorted position of the suspension strip and helical member when counterclockwise torque is applied to the cover portion.
FIG. 5 is a horizontal sectional view as seen on line 5-5 in FIG. 2 but showing the interengagement between the skirt and helical member when the designated areas are radially inwardly deformed as indicated by the arrows.
FIG. 6 is an elevational view of a modified form of cap made of a more rigid material having a pair of spaced slits formed in the skirt to provide a depressible tab for each designated deformable area, and
FIG. 7 is an elevational view of another modified form of cap having a shortened skirt for direct finger access to the helical member, a portion of the shortened skirt being broken away to show interior structure.
Description of the preferred embodiments Referring in detail to FIGS. 1 to 5, inclusive, of the drawing, 10 generally denotes a child-proof cap molded as an integral unit of a suitable elastomeric material, such as, polyolefins, polyvinyls, polyurethanes, ethylenevinylacetate and the like, to comprise a cover -11 and a helical or thread member 12. The cover 11 is formed with a top wall 11a and a peripheral skirt 1 3 and may also have an interior annular flange 14 concentric with the skirt 13 for fitting into and engaging the mouth 16a of a bottle 16.
Each suspension strip 15 may be formed to interlock with skirt 13 for movement therewith when the latter is deformed radially inwardly to engage strip 15. To this end, each strip 15 may be suitably shaped to project radially, here shown as being semicircular in cross-section, for fitting in tongue and groove fashion into a cradle 13a formed on the interior surface of skirt 13 in radial register therewith. Suitable means are provided to indicate the locations of cradles 13a and the areas for applying radially inward finger pressure, here shown as flat faces 13]) on skirt 13 which are centralized opposite cradles 13a.
The operation of child-proof cap 10 will now be apparent. Cap 10, molded as a one piece integral structure with helical member 12 supported in concentric relation to skirt 13, is threaded ontov bottle neck 160 by helical member 12 engaging threads 16b and tightened so that interior flange 14 enters and seals bottle mouth 16a. In this position helical member 12 grips bottle neck 16c by the lock thread action, that is, so that when counterclockwise torque 3 is applied to cover 11 to unscrew cap 10, the portion of helical member 12 remote from top wall 11:: will resist movement causing suspension strips 15 to flex from the normal position, here shown as parallel to the axis of helical member 12, to an oblique position as seen in broken lines in FIG. 4. This flexure in turn distorts helical member 12, tightening the grip on bottle neck 160. The lock thread action may be improved by providing the coils of helical member 12 with a minor diameter smaller than that of the bottle neck threads 16b.
To remove cap 10, skirt 13 is gripped by the thumb and two fingers at flat faces 13b. Radially inward pressure is then exerted to flex skirt 13 inwardly, as seen in FIG. 5, to engage at least one of the cradles 13a with its respective suspension strip 15. Simultaneously, torque is applied to unscrew the cap, flexure of suspension strips 15 and hence the lock thread action being prevented by skirt 13 and helical member 12 moving as a unit.
A modified form of cap 20 is shown in FIG. 6 which may be made of a more resilient material, such as, high impact styrene, acetal resin or nylon and the like. Cap 20 may be identical in construction to cap 10 except for a pair of spaced slits 13c which extend vertically up from the bottom edge 13d of skirt 13 on each of the flat faces 13b. Each pair of slits 13c provide a resilient tab 13e carrying the cradle for resiliently bending on application of inward radial pressure to engage suspension strip 15. Slits 13c and tabs 132 may also serve to indicate pressure areas so that skirt 13 may be made entirely circular or of another desired configuration eliminating flat faces 13b.
Another modified form of cap embodying the invention is shown in FIG. 7 as cap 30 comprising a cover 31, helical member 32 annular flange 34 and suspension strips 35 all similar to corresponding cover 11, helical member 12, annular flange 14 and suspension strip 15 of cap 10. In cap 30 skirt 33 is shortened to expose helical member 32 and strips 35' for direct finger manipulation when removal of cap 30 from a bottle neck is desired. As in cap 10, torque applied to cover 31 results in a lock thread action which may be overcome by gripping strips 35 directly with the fingers preferably adjacent the free ends thereof to rotate helical member 32.
The improved child-proof caps herein disclosed are seen to achieve the several objects of the invention and to be well adapted to meet conditions of practical use. As various possible embodiments might be made in this invention, and as various changes might be made in the disclosed constructions, it is to be understood that all matter herein set forth or shown in the accompanying drawing are to be interpreted as illustrative and not in a limiting sense.
