Abstract

A cap is for a container having both a child-resistant and a non-child-resistant closing position. In the child-resistant position, tabs or latches projecting from the container are wedged between a resilient lip and tabs or latches projecting from an inner surface of the cap. In the non-child-resistant position, the tabs or latches projecting from the inner surface of the cap are wedged between a holding unit, such as a bowl-shaped cap cover, and tabs or latches projecting from the inner surface of the cap.

Description

BOTTLE CAP, REVERSIBLE FIELD OF THE INVENTION The present invention is concerned with a child resistant reversible closure. More particularly, the invention is concerned with a lid that can be applied to a bottle or other container both in a child-resistant manner and not resistant to children.

BACKGROUND OF THE INVENTION Many different types of bottle closures are disclosed in the art. For example, U.S. Patent No. 5,449,078, which is expressly incorporated herein by reference in its entirety, describes the combination of a container and a safety cap therefor in which the safety cap has a flat of closure and an outer circumferential skirt for engaging with the container and having a circumferential resilient dependent internal member. The container has a rigid wall having an end for engagement with the cap internally of the outer skirt. The wall is tapered from a smaller diameter portion adjacent to the closing plane of the lid to a larger diameter portion remote from the closing plane of the lid. The tapered wall of the container engages internally with the resilient inner element of the cap and the larger diameter portion of the wall is said to expand the resilient internal member outwardly to provide a container working seal as well as an impulse on the lid in the direction of removal of the lid. The combination also includes means disposed on the container remotely from the end of the rigid wall and cooperating means on the lid to prevent the lid from being removed from the container without depression of the lid on the container and rotation of the lid on the container. While the cap resists children described in U.S. Patent No. 5,449,078 may prevent children from having access to the contents of a bottle or container, the cap may also present removal difficulties for an unproposed subset of the population. , in which the elderly are included, who lack the strength and / or manual dexterity to remove the lid. Thus, it is an aspect of the present invention to provide a reversible child-resistant closure that can be applied to a bottle or container both in a child resistant manner and not resistant to children.

DETAILED DESCRIPTION Figure 1 is a side view of an exemplary container system 10 of the present invention including a container, for example flask 12 and coupling cover 14. Cover 14 includes a circumferential skirt 16 having a ribbed outer surface. , which facilitates the grip and rotation of the lid 14. The bottle 12 includes four tabs 20 (only three visible) that are coupled with cam clips 22, in a child resistant position of the lid 14 (Figure 2) and with Modified pins 24, in a position not resistant to children (Figure 3). It should be understood that although four tabs 20 are mentioned any number of tabs 20 can be provided. The cam clips 22 and modified clips 24 project from an inner surface 30 of the circumferential skirt 16 and thus are shown in dashed lines. The lid 14 is locked on the bottle 12 in a child resistant position by first rotating about 45 degrees clockwise from the position shown in Figure 1, folding the lid 14 over the bottles 12, such that a tapered upper end 26 of the bottle 12 is disposed within the circumferential skirt 16 and such that each cam clip 22 is between two tabs 20 (one of the tabs 20 is in the marked position A (as seen in FIG. Figure 2) and rotate the lid 14 by approximately 45 degrees in the counterclockwise direction.Note that the necessary degrees of rotation are dependent on the number and arrangement of clips 22 and 24 arranged in the bottle 12. More or less than the four pins 22 and 24, and corresponding tabs 20, shown can be provided. The lid 14 is similarly blocked on the bottle 12 in a non-child resistant position except that the lid 14 is in an inverted or turned-over position before being placed on the upper end 26 of the bottle 12. Figure 2 illustrates a view side of the bottle 12 and a partial side view and partial cross-sectional view of the lid 14, which is locked on the bottle 12 in a child resistant position. The lid 14 includes a bowl-shaped cover 28 connected to the inner surface of the lid 14 by a ring portion 32 of the cover 28, which projects inwardly from the lid 14 and outwardly from the cover 28. The skirt circumferential 16 is selectively torn away in the distance to expose each cam clasp 22 and modified snap 24, projecting inwardly from the circumferential skirt 16. As such, the cam snap 22 and modified snap 24 are shown on a "floating" state. The circumferential skirt 16, which normally supports the clasps 22 and 24, has been torn to expose the engagement action of the tabs 20 and the cam locks 22 (Figure 2) and the modified snaps 22.

(Figure 3). The sides of the lid 14 are shown in section transversal. The cross section taken is through the center of each of the clips 22 and 24. A top perspective view of the lid 14 of Figure 2 is illustrated in Figure 2A, without the bottle 12 for clarity. The cam snap 22 includes an obstacle portion . 34, a central retention portion 36 and an inclined retention portion 38. Modified snap 24 includes an obstacle portion 40, a flat central portion 42 and a ramp portion 44. In the child resistant position illustrated in the Figure 2, as the lid 14 is rotated in the counterclockwise direction, the cam clip 22, initially in position A, slides along the marked path 29 such that the tab 20 slides upwardly of the inclined holding portion 38 and then it falls to the central retention portion 36. A flange resilient 46 of the bowl-shaped cover 28 is bent as the tab 20 and upper end 26 of the bottle 12 slides upwardly on the inclined holding portion 38 and applies a downward force on the vial 12 and tab 20 The obstacle portion 34 prevents further rotation of the lid in the clockwise direction. The inclined holding portion 38 prevents rotation of the lid in the counter-clockwise direction, that is, prevents separation of the lid 14, unless the lid 14 and vial 12 are first pressed towards each other , further bending the resilient flange 46 and raising the tongue 20 higher than the inclined retention portion 38. This extra step in separating the lid 14 adds effective child resistance to the container system 10. The cross section of the lid 14 is taken through the center of the clasps 22 and 24. Accordingly, the central retention portions 36 can be seen directly below the tabs 20 on either side of the lid 14. In contrast to the sides of the lid. lid 14, the bottle 12 is not shown in cross section, consequently, the tabs 20 can be seen wrapped around either side of the bottle 12. Although not shown (given the presentation in cross-section nsversal of the sides of the lid 14) the obstacle portion 34 and inclined retention portion 38 surround or sandwich these side tabs 20, in a manner analogous to the fully displayed cam snap 22 to the middle of the lid 14. Figure 3 illustrates a side view of the bottle 12 and a partial side view and partial side sectional view of the lid 14, which is locked on the bottle 12 in the non-child resistant position. The upper end 26 of the bottle sits in a channel 27 defined at least partially by the ring portion 32, the cover 28 and the circumferential skirt 16. The cover 14 is rotated from the portion A (in which the bottle 12 is covered for the lid 14 are not locked) in the clockwise direction, such that the modified clasp 24 (the center for purposes of illustration) slides along the path 29, such that the portion flat central 42 sits beneath the tab 20. The container system 10 is configured in such a way that in this locked position, the tabs 20 are snapped between the modified clasps 24 and the ring portion 32, which functions as a Retention unit. The upward and downward movement of the lid 14 in relation to the bottle 12 is prevented in this locked position by the ring portion 32 and the modified fasteners 24, which sandwich the tabs 20 of the top and bottom. Unlike the child resistant position, however, the rotation of the lid 14 is not impeded by a retainer. Rather, the rotation of the lid 14 can be effected by applying at least a predetermined level of rotation force to the lid 14 to separate the fraction between the flat center portions 42 of the modified fasteners 24 and the tabs 20 and between the upper end 26 of the bottle 12 and the ring portion 32. Alternatively, the container system 10 may further include an alternate projection ring or other projection (not shown) of the inner surface 30 of the circumferential skirt 16 between the cover 28 and the cam clips 22 to function as a holding unit. In such a case, the tongues 20 would be snapped and wedged between the modified clasps 24 and the reciprocating projection ring or other projection in the closed non-resilient position of the lid 14. Figures 4 to 6 illustrate another embodiment exemplary of the container system 10 of the present invention. To the extent that the parts or elements in Figures 1 to 3 coincide with those in Figures 4 to 6, a consistent numbering is maintained. Figure 4 is a side view of the container system 10. Four cam clips 22 are shown projecting from the bottle 12. The cam clips 22 either on one side or the other of the bottle 12 can be seen wrapped around the bottle 12. The lid 14 includes four tabs 20 and four modified tabs 48, shown in dashed lines, each projecting from the inner surface 30 of the lid 14. The lid 14 is blocked on the bottle 12 in a child resistant position. by first rotating approximately 45 degrees in the counterclockwise direction from the position shown in Figure 4, folding the lid 14 over the bottle 12, such that the tapered upper end 26 of the bottle 12 is disposed within the skirt circumferentially 16 and such that each tab 20 is between two cam clips 22 (one of the tabs 20 is in the position marked A) and the lid 14 is rotated by 45 degrees in the direction ión of the hands of the clock. The lid 14 is similarly blocked on the bottle 12 in a non-child resistant position except that the lid 14 is first inverted or turned over before placing it on the upper end 26 of the bottle 12. Note that the degree of rotation necessary for closure of the lid 14 is dependent on the number of cam clips 22 arranged on the surface of the bottle and the number of corresponding tabs 20. More or less than four cam clips 22 and corresponding tabs 20 can be provided. Figure 5 illustrates a side view of the bottle 12 and a partial side view and partial cross-sectional view of the lid 14 of Figure 4, which is locked on the bottle 12 in the child resistant position. The circumferential skirt 16 is selectively torn to leave exposed each of the tabs 20 and modified tabs 48 projecting inwardly from the circumferential skirt 16. As such, the tabs 20 and modified tabs 48 are shown in a "floating" state. . The circumferential skirt 16, which normally supports the tabs 20 and modified tabs 48, has been torn to expose the engagement action of the cam clasp 22 with the tabs 20 (Figure 5) and modified tabs (Figure 6). As Figures 2 to 4, the sides of the lid 14 are shown in cross section. The cross section taken is through the center of each of the tabs 20 and modified tabs 48. A top perspective view of the cover 14 of Figure 5 is illustrated in Figure 5A without the bottle 12 for clarity. As seen in Figure 5, rotation of the lid 14 forces the tongues 20 to slide along the path 50 downwardly along the inclined retention portions 38 and below the central retention portions 36. further, the rotation of the lid 14 forces the upper end 26 of the bottle 12 with the resilient flange 46 causing the flange 46 to bend, thus creating a downward impulse - on the bottle 12 and forcing the cam clips 22 against the tabs 20. The obstacle portion 34 of the cam clasp 22 prevents counter-clockwise rotation of the lid 14. In addition, the inclined retention portion 38 prevents rotation of the lid 14 in the clockwise direction , that is, opening the lid, unless the lid 14 and the bottle 12 are first forced towards each other, also bending the resilient rim 46 to be lower and thus clear the inclined retention portion 38. The Figure 6 illustrates a side view of the bottle 12 and a partial side view and partial cross-sectional view of the lid 14 of Figure 4, which is locked on the bottle 12 in the non-child resistant position. A top perspective view of the lid 14 of Figure 6 is illustrated in Figure 6A without the flask 12 for clarity. Dashed lines 33 are used to more clearly show the contours of the resilient flange 46 and the ring 32, which is hidden behind the resilient flange 46 from this perspective. As seen in Figure 6, the upper end 26 of the bottle sits in a chamber 27 defined at least partially by the ring portion 32, the cover 28 and the circumferential skirt 16. The cover 14 is rotated from the A position (in which the bottle 12 is covered but the lid 14 is not locked) in the clockwise direction of the hands, such that the modified tabs 48 slide down the inclined holding portion 38 and at least partially underneath. the central retention portion 36. The modified tabs 48 are too wide to fit between the obstacle portion 34 and the central retention portion 36. However, the container system 10 is configured in such a way that in this locked position, the modified tabs 48 are held under pressure between the cam clips 22 and the ring position 32. The upward and downward movement of the lid 14 relative to the bottle 12 is prevented by the cam snaps 22 and the cam portion. ring 32, which sandwich the modified tongues 48 of the upper part and lower part. Unlike the child resistant position, however, the rotation of the lid 14 is not impeded by the inclined retention portion 38 because, as indicated above, each of the modified tabs 48 is too wide to fit between the obstacle portion 34 and the inclined retention portion 38 of each cam clasp 22. Rather, the rotation of the cap 14 can be carried out by applying at least a predetermined level of rotational force to the cap 14. to overcome the friction between the inclined retention portion 38 and the modified tab 20 and between the upper end 26 of the flask 12 and the ring portion 32. Figure 7 illustrates another exemplary embodiment of the container system 10 of the present invention, identical to the embodiment of Figures 4 to 6, except for the resilient flange configuration 46. The resilient flange 46 also projects inwardly and is configured to be placed on the inside. The upper end 26 of the bottle 12 is furthermore. Also, as in the embodiment of Figures 4 to 6, the resilient flange 46 is configured to maintain a downward impulse on the upper end 26 of the bottle 12 when it is bent. Alternatively, the position of the tabs and clasps can be changed as in Figures 1 to 3, that is, the clips 22 and / or 24 can be projected inwardly from the circumferential skirt 16 and the tabs 20 or 48 can project outwardly of the bottle 12. In another exemplary embodiment of the present invention, the resilient flange 46 can be configured, for example in the form of an L, to engage with an upper edge of the bottle 12. Figure 8 illustrates another exemplary embodiment of the container 10 of the present invention. Figure 8 is a side view of the bottle 12 and a partial side view and partial cross-sectional view of the lid 14, which is locked on the bottle 12 in a non-child resistant position. The circumferential skirt 16 is selectively torn to expose each of the cam clips 22 and modified clips 24 projecting inward from the circumferential skirt 16. As such, the cam clips 22 and modified clips 24 are shown in a "floating" state. The circumferential skirt 16, which normally supports the cam clips 22 and modified clips 24, has been torn to expose the cam clips 22 and the engagement action of the modified snaps 24 and tabs 20. The sides of the lid 14 are shown in cross section. The cross section taken is through the center of the side cam fasteners 22 and modified fasteners 24. The lid 14 includes a central cover 56 that divides the circumferential skirt 16 at the center. Upper and lower resilient flanges 46 and 54 project in opposite directions from the central cover 56. On one side of the central cover 56 the cam clips 22 project inward from the circumferential skirt 16 and on the opposite side of the center cover 56 the modified clips 24 project inward from the circumferential skirt 16. Rotation in the clockwise direction of the lid 14 forces the tabs 20 to slide up along the ramp portion 38 and over the flat central portion 42, along the marked path 52. The rotation of the lid 14 forces the upper end 26 of the bottle 12 against the resilient flange 46 causing the flange 46 to bend, creating a pulse 'from the bottle 12 downwards. The obstacle portion 34 of the cam clasp 22 prevents rotation in the additional clockwise direction of the lid 14. In addition, the friction between the resilient flange 46 and the upper end 26 of the flask 12 and between the modified snap 24 and the tongue 20 resists the rotation of the lid 14 in the opposite direction to the hands of the clock, that is, opening of the lid. However, the container system 10 is configured in such a way that the application of a threshold rotation force to the lid 14 overcomes this friction. In the child resistant position (with the cover 14 inverted) the configuration and fixing action of the cover 14 is identical to that of Figure 2. The rotation of the cover 14 forces the tongue 20 on the inclined holding portion. 38 and over the central retention portion 36, fixing the tab 20 between the obstacle portion 34 and the inclined retention portion 38. In this locked position rotation of the cap 14 in one direction is prevented by the obstacle portion 34 and the rotation of the lid 1.4 in the opposite direction can be carried out only by pressing the lid 14 and the bottle 12 towards each other, to raise the tongue 20 in relation to the camper 22, as long as it is made rotate the lid 14. Alternatively, the modified clips 24 may have the same configuration as the cam clips 22 but have a shorter central retention portion 36. In addition, the position of the tabs and clasp s can be changed as in Figure 4, that is, the clips can be projected inwardly from the circumferential skirt 16 and the tabs can project outwardly from the bottle 12.

The lid 14, in all the modalities detailed above, can be formed integrally and manufactured from a plastic, for example high density polyethylene.

(HDPE), low density polyethylene (LDPE) and polypropylene. In addition, in all the above exemplary embodiments a larger number or manner of corresponding pins and tabs may be used. Since many widely different embodiments of the present invention can be manufactured without departing from the spirit and scope thereof, it will be understood that the present invention is not limited to the specific embodiments thereof except as defined in the appended claims.
