Definitions
- the present invention relates to aerosol packages in which the container is adapted to hold contents under pressure and more particularly to a blow molded plastic container for such a package.
- Containers for aerosol packages typically are of glass or metal construction so as to possess sufficient strength to hold the package contents under pressure without distortion of the container.
- a general object of the present invention is to provide a blow molded plastic container for aerosol package applications in which the container body has an oval cross-section, in which the container base is contoured to retain the oval cross-section of the container body under aerosol pressure, and in which the neck finish is particularly well adapted to facilitate handling during manufacture.
- a plastic container for holding aerosol contents under pressure in accordance with presently preferred embodiments of the invention includes a one-piece integrally molded plastic body having a base, a sidewall and a neck finish.
- the sidewall and the base are of oval cross-section, and the base has a contour and cross-section for maintaining the oval cross-section under aerosol pressure within the container body.
- the neck finish has an open mouth surrounded by a circumferentially continuous external bead for securing a dispensing closure.
- the bead has an undersurface that is perpendicular to an axis of the neck finish, and the neck finish has a chamfered inside edge around the open mouth to facilitate insertion of a dispensing closure.
- the neck finish includes a support flange spaced from the external bead.
- the support flange has a peripheral edge with at least one locating element for orienting the oval cross-section in automated equipment for assembling the dispensing closure to the container.
- the base preferably is a champagne base having a central outwardly oriented convex portion and a peripheral standing ring.
- the standing ring preferably has a thickness that is 2 to 2.5 times the thickness of the container sidewall.
- FIG. 1 is a front elevational view of a container in accordance with one presently preferred embodiment of the invention
- FIG. 2 is a side elevational view of the container in FIG. 1;
- FIG. 3 is a partially sectioned top plan view of the container in FIG. 1;
- FIG. 4 is a fragmentary sectional view on an enlarged scale of the portion of FIG. 3 within the area 4;
- FIG. 5 is a fragmentary sectional view on an enlarged scale of the portion of
- FIG. 2 within the area 5;
- FIG. 6 is a fragmentary sectional view that illustrates the base of the container in FIGS. 1-3;
- FIG. 7 is a front elevational view of a container in accordance with another embodiment of the invention.
- FIG. 8 is a partially sectioned top plan view of the container in FIG. 7;
- FIG. 9 is a fragmentary sectional view of the portion of FIG. 8 within the area 9;
- FIG. 10 is a sectional view of an aerosol dispensing closure that can be used with the container of FIGS. 1-6 or FIGS. 7-9. Detailed Description of Preferred Embodiments
- FIGS. 1-6 illustrate a container 20 in accordance with one presently preferred embodiment of the invention.
- Container 20 is of one-piece integrally blow molded construction having a body 22 with a base 24, a sidewall 26 and a neck finish 28.
- Sidewall 26 and base 24 are of oval construction, as best seen in FIG. 3.
- Neck finish 28 is cylindrical and has a circumferentially continuous external bead 30 that surrounds the open mouth of the container.
- Bead 30 has an undersurface 32 that is flat and planar on an axis perpendicular to the axis of the neck finish.
- Flat undersurface 32 provides positive alignment with in-feed and out-feed jaws on two- stage reheat stretch blow molding equipment.
- undersurface 32 provides for secure crimping of an aerosol dispensing closure (FIG.
- t Neck finish 28 preferably also includes an external support flange 36, sometimes termed a capping flange or a transfer flange, spaced from the open mouth of the container.
- Flange 36 is circumferentially continuous and perpendicular to the axis of the neck finish.
- Flange 36 has a peripheral edge that preferably includes at least one locating element 38 for orienting the oval cross-section of container 20. In the embodiment of FIGS.
- the locating element 38 is a notch on the periphery of the flange aligned with the minor axis of the oval container cross-section, as best seen in FIG. 3.
- Notch 38 can be used by automated capping equipment for locating the dispensing closure angularly with respect to the container finish so that the closure dispenses product at a desired orientation with respect to the container cross-section, such as in the direction of the minor axis of the container.
- the preferred construction of container base 24 is illustrated in FIG. 6.
- Base 24 preferably is a so-called champagne base, having an outwardly convex central portion or dome 40 and a peripheral standing ring 42.
- the thickness 44 of standing ring 42 preferably is 2 to 2.5 times the thickness 46 of container sidewall 26.
- Base 24 is designed to rigidify the container sidewall and maintain the oval contour of the container sidewall under pressure within the container.
- FIGS. 7-9 illustrate a container 50 in accordance with a second embodiment of the invention.
- Container 50 is essentially the same as container 20 in FIGS. 1-6 except for the locating elements on the neck finish support flange 36.
- the locating elements on the support flange comprise a pair of outwardly extending lugs 52 on diametrically opposed sides of neck finish 28 at the minor axis of the oval container cross-section.
- FIG. 10 illustrates a conventional aerosol dispensing closure 60, which includes a metal ring 62 that is crimped over bead 30 for securing the dispensing closure to the aerosol container of the present invention.
- the container of the present invention can be made employing any suitable manufacturing technique.
- the container preferably is made in a reheat blow molding process, in which a preform is first constructed such as by injection or compression molding, and the perform is then reheated and blow molded to form the container body.
- the container neck finish including bead 30 and support flange 36, preferably are formed at the preform stage.
- the container can be of any suitable plastic material such as polyethylene terephthalate (PET), and can be of monolayel construction or multilayer construction that includes one or more internal barrier layers such as nylon or ethylene vinyl alcohol (EVOH).
- PET polyethylene terephthalate
- EVOH ethylene vinyl alcohol
- one of the layers of a multilayer sidewall construction can have a high glass, transition temperature Tg, which helps resist deformation of the container body.
- the container sidewall can have a two-layer construction: (1) PET having a thickness of 0.042 inch and a glass transition temperature of 7O 0 C, and (2) amorphous nylon having a thickness of 0.028 and a glass transition temperature of 115°C.
