Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of the invention relate to devices and mechanisms for attaching a closure, pump, trigger, valve, or other device to a bottle and in particular, mechanisms and methods for attaching closures, pumps, triggers, or other devices to pressurized bottles.

2. State of the Art

Pressurized bottles and containers are used in many different industries. One of the most widely known uses of pressurized bottles in commercial markets includes aerosol bottles and containers. Aerosol bottles and containers generally hold pressurized gases, gases and liquids, or liquids.

Conventional aerosol bottles are constructed of one or more metals and are typically found in a cylindrical shape which may assist in supporting the pressure inside the aerosol bottle. Closure fitments, such as pumps, valves, triggers, or other devices may be attached to an aerosol bottle to close the bottle and to provide access to the contents of the bottle. The closure fitments are typically sealed to the rim or neck of the aerosol bottle such that they cannot be easily removed.

Increasing costs of metal and difficulties in recycling pressurized metal containers have made it desirable to develop other types of containers, such as plastic containers, and closures systems for such containers. Therefore, it would be advantageous to develop a closure system that may be used with plastic bottles or containers and especially with plastic bottles or containers that may be pressurized or used for aerosol delivery systems.

DETAILED DESCRIPTION OF THE INVENTION

According to embodiments of the invention, a snap-fitment system may be used to attach a closure, pump, trigger, or other device to a pressurized bottle. While various embodiments of the invention are described with respect to a closure being attached to a bottle or container, it is understood that a closure may include, but is not limited to, pumps, triggers, distribution means, valves, or other devices.

According to embodiments of the invention, a valve cup 300 may include one or more fingers 310 which may be used to attach the valve cup 300 to a container 100. As illustrated in FIG. 1, one or more fingers 310 of a valve cup 300 may be compressed by a retaining ring 200 about a container flange 110. The retaining ring 200 may hold the fingers 310 about the container flange 110 such that pressure in the container 100 may be maintained or so that the valve cup 300 is secured to the container 100.

According to certain embodiments of the invention a snap-fitment system may include a valve cup 300, a valve system 400, and a retaining ring 200 as illustrated in FIGS. 2 and 3. The valve cup 300 may include one or more fingers 310. A retaining ring 200 may encompass at least a portion of the fingers 310 of the valve cup 300. As illustrated in FIG. 2, the retaining ring 200 may also include one or more lips 201 which may be snapped about one or more fingers 310 such that the retaining ring 200 and the valve cup 300 may be distributed as a single unit. The retaining ring 200 may include a cylindrical portion and a flared portion wherein the flared portion fits about the fingers 310 of the valve cup 300 as in the position illustrated in FIG. 2.

The valve system 400 illustrated in FIG. 2 may include a valve stem 410 positioned in a valve housing 420. A valve gasket 430 may be positioned between a portion of the valve housing 420 and an underside of the valve cup 300 as conventionally known. The valve cup 300 may also include one or more lips, platforms, or other projections which may be used to hold the valve system 400 in a position relative to the valve cup 300 as illustrated in FIG. 2.

The snap fitment system illustrated in FIG. 2 may be attached to a container 100 to form a seal between the snap fitment system and the container 100. For example, the snap fitment system illustrated in FIG. 2 may be placed over a container 100 such that the valve cup 300 rests over an opening in the container 100 as illustrated in FIG. 4. A valve cup gasket 350 may be positioned between an underside of the valve cup 300 and the flange 110 of the container. The retaining ring 200 may be forced in a direction towards the container 100, causing the fingers 310 of the valve cup 300 to collapse about the flange 110 of the container 100. As the force on the retaining ring 200 is applied, the fingers 310 of the valve cup 300 wrap around the flange 310 of the container 100 securing the snap fitment system to the container 100 as illustrated in FIG. 1.

According to certain embodiments of the invention, a valve cup 300 may include two or more fingers 310 as illustrated in FIG. 5. For example, the valve cup 300 may include two fingers 310, three fingers 310, four fingers 310 or more. The fingers 310 may be symmetrically arranged about the valve cup 300 or may be asymmetrical. Spacing between the fingers 310 may be consistent or inconsistent. Any number of fingers 310 may include projections, bumps, or other features at the end of the fingers 310 such that such projections, bumps, or other features may wrap around or underneath a container flange 310. The projections, bumps, or other features may be configured to help clasp or otherwise hold the snap fitment system to a container 100.

According to some embodiments of the invention, the retaining ring 200 may include one or more crush ribs 210 as illustrated in FIG. 2. The crush ribs 210 may deform when the retaining ring 200 is forced about the fingers 310 of the valve cup 300. Deformation of the crush ribs 210 may hold the retaining ring 200 in place once it has secured the fingers 310 about a flange 110 of a container 100. In other embodiments, the retaining ring 200 may include snap fitments in the place of, or in addition to, crush ribs 210. As a retaining ring 200 is pushed down over a valve cap 300 and the fingers 310, the snap fitments may pop into the spaces between the fingers 310 and may snap into place with a portion of the valve cup 300 thereby preventing the retaining ring 200 from backing off of the position about the fingers 310 of the valve cup 300.

The valve cup 300 and retaining ring 200 of various embodiments of the invention may be made of any suitable material, including, but not limited to, plastic materials, metals, composites, or other materials. Similarly, the containers 100 to which the snap fitment systems according to embodiments of the invention may include plastic containers, glass containers, metal containers, or other containers.

As illustrated in FIG. 6, the snap fitment system may include a valve cup 300 having one or more fingers 310 which may be positioned around or on a container 100. The container 100 may include one or more container flanges 110 mated with one or more fingers 310 when a retaining ring 200 is positioned over or about the valve cup 300. The valve system 400 may include any conventional valve system. A gasket may also be located between the container 100 and the valve cup 300.

FIG. 7 illustrates a valve system 400 incorporated or fitted into a valve cup 300 according to embodiments of the invention. The valve housing 420 may be held in place with respect to the valve cup 300 by one or more valve housing connectors 315 in the valve cup 300. The valve housing connectors 315 may include, but are not limited to, detents, indentations, snap fitments, bayonets, threaded systems, or other devices for retaining a valve housing 420 in a valve cup 300.

A retaining ring 200 may be incorporated with the valve system 400 and valve cup 300 as illustrated in FIGS. 8 and 9. The retaining ring 200 may be fitted over a portion of the valve cup 300 and fingers 201 on the retaining ring 200 may secure the retaining ring 200 to the valve cup 300 through interference with one or more fingers 310. The valve cup 300, retaining ring 200, and valve system 400 are part of the snap fitment system that may be shipped, transported, sold, or otherwise manipulated as desired.

The snap fitment system illustrated in FIGS. 8 and 9 may be placed over a container opening as illustrated in FIG. 10. The fingers 310 of the valve cup 300 may be forced past one or more container flanges 110 of a container 100. When the snap fitment system is fitted onto a container 100, the retaining ring 200 may be forced downward with respect to the valve cup 300 such that the retaining ring 200 forces fingers 310 to firmly attach or mate with one or more container flanges 110 as illustrated in FIG. 6. In this manner, a valve may be attached to a container 100 as desired.

According to various embodiments of the invention, a snap fitment system may be attached to an aerosol container to provide an aerosol disbursement system.
