Description

CHILD-RESISTANT PACKAGE

BACKGROUND OF THE INVENTION

1. Field of the invention

The invention relates to a package for dispensing and delivering product. The invention further relates to a child-resistant package. The invention still further relates to a closure for a child-resistant package. The invention still yet further relates to a container for a child-resistant package.

2. Description of the Prior Art Child-resistant packages have been developed for use in dispensing products deemed potentially harmful to children if imbibed or otherwise exposed. Such packages typically comprise a container and a closure. The closure typically requires mechanical manipulation to unscrew or decouple is from the container. Some common types include push-and-tum and squeeze-and-turn. Such packages have commonly been employed with tubular plastic dispensing containers.

Some squeeze-and-turn tubular plastic dispensing containers have employed locking lugs on the base or shoulder of a container to engage portions of a closure. Examples of such packages are shown in Great Britain Patent Application 2,030,970 A1 and U.S. Patent Nos. 4,335,823; 4,413,743; 5,145,080; 5,988,412; 5,915,576; 6, 112,921 and 6,357,615 B1.

Squeeze-and-turn tubular plastic dispensing containers have heretofore been unavailable in small diameter sizes, i.e., 0.50 to 0.75 inch in base or shoulder diameter. Containers of small diameter are difficult to design because of the relatively small circumference available to achieve mating between lugs and the closure. It would be desirable to have a child-resistant package of small diameter size. It would further be desirable to have a child-resistant package of the squeeze-and-turn type. It would further be desirable to have a child-resistant package employing locking lugs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following are preferred aspects and features of the present invention.

A preferred slot in the closure can be substantially the same shape as the portion of the lug to be received therein. The slot defines a vertical edge adjacent thereto, and the vertical edge is generally directional with respect to the longitudinal extension of the outer skirt. The slot extends angularly from the edge of the outer skirt therein to the vertical edge.

A preferred lug defines a flat surface generally directional with the longitudinal extension of the neck. The flat surface is engaged with the vertical edge when the closure is in locking position with the head. In one embodiment, the lug extends from the neck radially outward. The lug is substantially free of contact with the neck. In another embodiment, the lug has a notch therein at an outer portion thereof with the notch bearing a flat surface. In a preferred embodiment, there are two lugs extending from the shoulder with the two lugs being positioned oppositely about the neck. Preferably, the height of the lug is about one-half of the pitch of the thread on the outer surface of the neck.

In a preferred closure, the outer surface of the outer skirt defines knurls therein extending generally from the bottom edge toward the top end of the closure. The inner surface of the outer skirt has one or more ribs extending from about the middle thereof toward the top end to mechanically strengthen the closure. Most preferably, there are three to six ribs. The shoulder has a more preferred diameter of about 0.5 to about 0.75 inch and a most preferred diameter of about 0.6 inch. The inner and outer skirts are most preferably tapered inward about 0.5° (degrees) with respect to the longitudinal extension of the closure to enhance moldability during injection molding of the closure. The closure preferably has a plug seal extending circu inferential ly from the top end generally directional to the longitudinal extension of the closure. The plug seal is adapted to fit within and seal the orifice when the closure is in locking position with the head. In lieu of a plug seal, the closure may have a foam layer situated at a central area of an inner surface of the top end thereof. The foam layer would be adapted to fit over and seal the orifice when the closure is in locking position with the head. The shoulder can be sloped or flat in shape. The thread on the neck preferably has a pitch of about 0.1 to about 0.12 inch and most preferably a pitch of about 0.1 inch. In addition to having an initial full thread generally in alignment with a lug directional with the longitudinal extension of the neck, a preferred dispensing container also has a terminal full thread generally in alignment same.

An embodiment of a dispensing tube package is shown in Figure 1 and is generally referenced by the numeral 10. Package 10 has a dispensing container 20 and a closure 12 engageable and lockable with container 20. Closure 12 is shown in isolation in Figure 2. As shown in Figure 5, container 20 has a body wall 16 and a head 22. Head 22 has a neck 24 and a shoulder 26. Body wall 16 defines a chamber 28 therein. Neck 24 communicates with body wall 16 via shoulder 26. Neck 24 has an orifice 28 therein and a passageway 30 therethrough extending from orifice 28 to chamber 28.

As shown in Figures 6 and 7, lugs 32 and 34 extend from shoulder 26 radially outward from neck 24 to adjacent the periphery of shoulder 26. Lugs 32 and 34 are situated generally oppositely about neck 24. Lugs 32 and 34 define flat surfaces 52 and 54 and angled surfaces 56 and 58, respectively. In lug 32, angled surface 56 slopes upward from shoulder 26 to intersect with flat surface 52, which extends generally directionally with the longitudinal extension of neck 24. In lug 34, angled surface 58 slopes upward from shoulder 26 to intersect with flat surface 54, which extends generally directionally with the longitudinal extension of neck 24. Lugs 32 and 34 take the general shape of a triangloid or a wedge. Thread 36 extends from an upper portion of neck 24. Thread 36 has a pitch of about 0.08 to about 0.16 inch. Thread 36 has an initial full thread 60 and a terminal full thread 62 generally in alignment with flat surface 52 of lug 32 directional with the longitudinal extension of neck 24. As shown in Figures 3 and 4, closure 12 has a top end 38 having a generally circumferential outer skirt 40 extending therefrom. Closure 12 also has a generally circumferential inner skirt 42 extending therefrom inside outer skirt 40. Inner skirt 42 has a thread 46 extending from its inner surface. Thread 36 of neck 24 can be screwed into thread 46 of inner skirt 42. Outer skirt 40 terminates at a first edge 48 opposite top end 38. Inner skirt 42 terminates at a second edge 50 opposite top end 38. Outer skirt 40 has a slot 14 and another slot 15 oppositely situated thereabout that extend inwardly therein from first edge 48. Slot 14 has an angled edge 62 that angles and curves inward into outer skirt 40 and intersects a vertical edge 64 that is generally directional with respect to the longitudinal extension of outer skirt 40. Slot 15 has an angled edge 66 that angles and curves inward into outer skirt 40 and intersects a vertical edge 68 that is generally directional with respect to the longitudinal extension of outer skirt 40. Slots 14 and 15 are adapted to receive an outer portion of each of lugs 32 and 34, respectively, when closure 12 is in locking position with head 22 as shown in Figures 1 and 8. Slots 14 and 15 slide over and/or around the outer portion of lugs 32 and 34 as closure 12 is screwed on container 20. In locking position, verticle edge 64 is generally in abutment with or adjacent to vertical surface 52 and vertical edge 68 of slot 15 is generally in abutment with or adjacent to vertical surface 54. Further in locking position, angled edge 62 is generally in abutment with or adjacent to angled surface 56 and a corresponding angled edge (not shown) of slot 15 is generally in abutment with or adjacent to angled surface 58.

Closure 12 defines knurls 18 and 19 therein at the outer surface of outer skirt 40 extending from first edge 48 toward top end 38. Knurls 18 and 19 provide a gripping surface for the fingers (not shown) to squeeze, turn and remove closure 12 from container 20. When closure 12 is squeezed at knurls 18 and 19, the portions of outer skirt 40 having slots 14 and 15 therein are forced outward, thereby releasing lugs 32 and 34 from their locking position with slots 14 and 15.

An embodiment of a dispensing container is shown in Figure 12 and is generally referenced by the numeral 80. Closure 12 is shown in isolation in Figure 2. Container 80 has a body wall 88 and a head 82. Head 82 has a neck 84 and a shoulder 86. Body wall 88 defines a chamber 89 therein. Neck 84 communicates with body wall 88 via shoulder 86. Neck 84 has an orifice 94 therein and a passageway 98 therethrough extending from orifice 94 to chamber 89.

As shown in Figures 13 to 16, lugs 90 and 92 radially extend from shoulder 86 from neck 84 to adjacent the periphery of shoulder 86. Lugs 90 and 92 are situated generally oppositely about neck 84. Lugs 90 and 92 define flat surfaces 100 and 102, normal surfaces 104 and 106 and angled surfaces 108 and 110, respectively. In lug 90, angled surface 108 slopes upward from shoulder 86 to generally intersect with flat surface 100, which extends generally directionally with the longitudinal extension of neck 84. Normal surface 104 also extends generally directionally with the longitudinal extension of neck 84 and is also generally perpendicular with respect to flat surface 108. In lug 92, angled surface 110 slopes upward from shoulder 86 to generally intersect with flat surface 102, which extends generally directionally with the longitudinal extension of neck 84. Normal surface 106 also extends generally directionally with the longitudinal extension of neck 84 and is also generally perpendicular with respect to flat surface 102. The relative configuration of flat surfaces 100 and 102 and normal surfaces 104 and 106 provides lugs 90 and 92 with a "notched" appearance.

Thread 96 extends from an upper portion of neck 84. Thread 96 has a pitch of about 0.08 to about 0.16 inch. Thread 96 has an initial full thread 112 and a terminal full thread 114 generally in alignment with flat surface 100 of lug 90 directional with the longitudinal extension of neck 84.

Slots 184 and 186 slide over and/or around the outer portion of such lugs. In locking position, verticle edges 192 and 194 are generally in abutment with or adjacent to the vertical surface of such lugs. Closure 170 has a plug seal 200 extending circumferentially from top end 172 generally directional to the longitudinal extension of closure 170. Plug seal 200 is adapted to fit within and seal an orifice of a head of a dispensing container when closure 170 is in locking position therewith.

An embodiment of a dispensing container is shown in Figure 21 and is generally referenced by the numeral 210. Container 210 has a body wall 218 and a head 212. Head 212 has a neck 214 and a shoulder 216. Body wall 218 defines a chamber 219 therein. Neck 214 communicates with body wall 218 via shoulder 216. Neck 214 has an orifice 224 therein and a passageway 228 therethrough extending from orifice 224 to chamber 219.

As shown in Figures 21 to 23, lugs 220 and 222 radially extend from shoulder 216 from neck 214 to adjacent the periphery of shoulder 216. Lugs 220 and 222 are situated generally oppositely about neck 214. Lugs 220 and 222 define flat surfaces 230 and 232, knobs 234 and 236 and inwardly tapered surfaces 238 and 240 and 242 and 244, respectively. The inwardly tapered surfaces at the outer portion of lugs 220 and 222 function to slow down the Flat surfaces 230 and 232 are generally planar in surface contour and extend from shoulder 216 generally directional with and generally radial to the extension of neck 214. A preferred height for lugs 220 and 222 is 0.1 inch as measured from shoulder 216 to the top of flat surfaces 230 and 222. Knobs 234 and 236 extend from shoulder 21 and lugs 220 and 222, respectively. Dispensing tube 210 has a double-lead screw. In other words, there are two intermating threads 225 and 226 that extend from and spirally traverse neck 214. The threads have a pitch of about 0.15 to about 0.3 inch and preferably about 0.2 inch. Thread 225 has an initial full thread 233 and a terminal full thread 231. Thread 226 has an initial full thread 234 and a terminal full thread 232. An important feature of the invention is that initial full threads 233 and 234 are generally in alignment with lugs 220 and 222 directional with the longitudinal extension of neck 214. Although terminal full threads 231 and 232 are also generally in alignment with lugs 220 and 222 directional with the longitudinal extension of neck 214, this is not important to the present invention. Other possible dispensing tube embodiments could have multiple-lead screws, such as triple-lead, quadruple lead, and the like.

Dispensing tube 210 is mated with closure 246 to form dispensing tube package 248, which is shown in Figures 22 and 23. Closure 246 is engageable and lockable with dispensing containers of the present invention, including container 210. As shown in Figures 23 to 25, closure 246 has oppositely situated slots 250 and 252, which are adapted to receive an outer portion of each of lugs 220 and 222, respectively, when closure 246 is in locking position with head 212. Slots 250 and 252 slide over and/or around the inwardly tapered surfaces of the outer portion of lugs 220 and 222 as closure 246 is screwed on container 210. The inwardly tapered surfaces at the outer portion of lugs 220 and 222 function to slow down the rotation speed of closure 246 such that lugs 220 and 222 will snap into slots 250 and 252. The outer portions of lugs 220 and 222 protrude through slots 250 and 252 when closure 246 is in locking position with head 212. Slots 220 and 222 define oppositely situated vertical edges 254 and 256 (not shown) at their leading edges. When in locking position, vertical edge 254 of closure 246 is generally in abutment with or adjacent to flat surface 230 and vertical edge 256 of slot 222 is generally in abutment with or adjacent to flat surface 232. Closure 246 has knurles 258 and 260 to aid in squeezing, turning, and removal of same. Knobs 234 and 236 provide a support surface against which the inside surface (not shown) of closure 246 may rest. Apart from the aforementioned recited structure, closure 246 has additional structure corresponding to the other disclosed closure embodiments herein, including, but not limited to inner and outer skirts, mating threads, plug seals, and the like. The package, including dispensing container and closure, may be produced by any method known in the art such as extrusion or lamination. In extrusion, plastic tubes are extruded continuously then cut into discrete lengths to form tubular body walls for the inner and outer containers. Tubes of different diameters are used the inner and outer containers. Heads are then heat welded or adhered to the tube lengths of both diameters to form the inner and outer containers. The inner container is inserted into the open end of the outer container and attached to or inserted into the head and/or neck of outer container. A closure, cap or top is applied to the head of the outer container. The open ends of inner and outer containers are typically filled with functional and/or decorative products to be dispensed and then sealed by heat or mechanical means. Overlapping the ends and heat sealing is preferred. In lamination, sheets of plastic material are rolled into tubes and sealed along the sheet edges to form continuous tubes. The continuous tubes are cut into discrete tube lengths and further processed in the same manner as when forming extruded dispensing containers. The closure and head may be manufactured according to any method known in the art such as injection molding, compression molding or stamping with a plastic material. Injection molding is preferred. The package may be manufactured from any plastic material known in the art. Representative plastic materials include ethylene polymers, propylene polymers, polyesters, and polyamides. Useful ethylene polymers include low density polyethylene, medium density polyethylene, high density polyethylene and linear low density polyethylene. A useful propylene polymer is polypropylene. Useful polyesters include polyethylene terephthalate. Preferred plastic materials are low density polyethylene and polypropylene. Different parts of the package may be manufactured from the same or different materials. A preferred plastic material for tube body walls is low density polyethylene. Preferred plastic materials for the head and the closure are high density polyethylene and polypropylene.

It should be understood that the foregoing description is only illustrative of the present invention. Various alternatives and modifications can be devised by those skilled in the art without departing from the invention. Accordingly, the present invention is intended to embrace all such alternatives, modifications and variances which fall within the scope of the appended claims.
