2,998,165 PRESSURE CONTAINER FOR PERFUME SPRAY John De Elorza, Mount Prospect and Verona Aves., Newark, NJ. Filed Feb. 5, 1959, Ser. No. 791,426 Claims. (Cl. 222-182) The present invention is directed to dispensers for various liquid products, more particularly to containers of such products under gas pressure in order to dispense the products in the form of a spray.

Pressure containers for this purpose have been known and in common use. They consisted. of either a glass or metal container filled with a liquid to be dispensed and a gaseous propellant with a valve for normally closing the container. Means are provided whereby the valve may be opened and the material sprayed automatically therefrom. Such containers are either of metal or of glass, the latter being fragile and readily subject to breakage. Neither of these types of containers are capable of being adequately decorated and neither of them is refillable. It has been proposed to enclose the glass container within a metal casing in order to minimize the danger of breakage but such containers were permanently secured in the casings so that they could not be renewed or replaced.

It is among the objects of the present invention to modify and improve the devices of the prior art and to provide a structure of pressure container which will allow the pressure unit to be replaced and particularly for the purpose of providing a refillable glass pressure structure.

It is also among the objects of the present invention to provide a device of the type described, wherein a casing is provided which lends itself to decorative designs in many colors.

It is further among the objects of the present invention to provide a pressure container structure which is simple in construction, inexpensive and eflicient in use.

In practicing the present invention, there is provided the usual cylindrical pressure container made of either glass or metal. There is provided a casing generally of metal or plastic material which surrounds the container and fits closely thereto. A plurality of indentations are formed in the casing near the upper end thereof so that when the container is inserted in the casing, the indentations will fit over a shoulder or the like on the container and retain the same in position against accidental displacement. The material of which the casing is made has sufficient resiliency so that the container may be inserted into the casing, distorting the casing temporarily, allowing the indentations to snap into position over the shoulder. Similarly, the container may be removed from the casing for replacement purposes.

In the accompanying drawings'constituting a part hereof and in which like reference characters indicate like P FIG. 1 is a perspective view of a pressure container structure made in accordance with the present invention;

FIG. 2 is a longitudinal cross-sectional view thereof, and

FIG. 3 is a transverse cross-sectional view taken along line 33 of FIG. 2.

Pressure container 1 is of usual construction and is shown in FIGS. 2 and 3 by broken lines. It has a stem at the upper end thereof having a central opening 3 for the flow of atomized liquid from container 1, said stem extending from neck 4 of the container. A shoulder 5 is formed along the top of the container where it meets neck 4.

Casing 6 is of such a diameter that container 1 fits snugly therein. The casing is provided with a series of indentations 7, usually three or four in number and equally spaced near the upper end thereof. Said indentations are adapted to snap over shoulder 5 and prevent relative move ment of container and casing and prevent accidental dis-' placement of the container from the casing. A cap 8 fits over casing 6 and is frictionally held thereon. Top 9 of cap 8 is slightly concave to readily accommodate the thumb or finger of the user.

Within cap 9 at the top thereof is an insert 10 usuallymade of synthetic plastic material. Said insert has 21' depending neck 11 formed with a recess 12 stem 2 is adapted to cesses 12 extends to nozzle 14 on the outside of cap'B.

In the operation of the invention, container 1 is slipped into casing 6 until indentations 7 overlap shoulder '5.' Cap 8 is placed over casing 6, extending below the level of said indentations. T o operate the device, the thumb is placed on top 9, pressure is applied, forcing stem 2 partly into the container, thereby opening a valve and allowing a mixed spray of liquid and propellant to pass through opening 3, passage 13 and nozzle 14. When the container is empty, it may readily be removed by removing cap 8, grasping either element 2 or 4, and pulling the container out of the casing, which is permitted by the distortion of the casing due to the resiliency of the material thereof.

There are a number of advantages inherent in the present invention. For instance, casing 8 may be made of highly decorative material and of precious metal and the pressure unit replaced from time to time. The casing may be made of flat material which is lithographed and then formed into a casing by the usual methods of rolling and crimping. This makes a relatively inexpensive structure. Another advantage is that glass containers may be used without danger of breakage while at the same time the device is so made that the glass container may be replaced after it is exhausted.

vI claim:

1. A pressure container structure comprising a substantially cylindrical container, a restricted portion near the upper end of said container forming a shoulder, a casing surrounding said container and fitting closely, an indentation near the upper end of said casing and extending sufficiently over said shoulder to retain said container in said casing to prevent accidental displacement thereof, a hollow stem at the top of said container, a cap on said casing, an insert in said cap having a recess adapted to accommodate said stem, and a passage from said recess to the outside of said cap.

2. A pressure container structure comprising a substantially cylindrical container, a restricted portion near the upper end of said container forming a shoulder, a casing surrounding said container and fitting closely, a plurality of indentations around the periphery and near the upper end of said casing and extending sufficiently over said shoulder to retain said container in said casing to prevent accidental displacement thereof, a hollow stem at the top of said container, a cap on said casing, an insert in said cap having a recess adapted to accommodate said stem, and a passage from said recess to the outside of said cap.

3. A pressure container structure comprising a substantially cylindrical container, a restricted portion near the upper end of said container forming a shoulder, a casing surrounding said container and fitting closely, an indentation near the upper end of said casing and extending sufiiciently over said shoulder to retain said container in said casing to prevent accidental displacement thereof, a hollow stem at the top of said container, a cap on said casing, said cap extending to a point below said indentation and frictionally held on said casing, an

into which fit snugly. A passage 13 fromre casing, an indentation near the upper end of said casing;

and extending sufficiently over said shoulder to retain said container in said casing to prevent accidental displacement thereof, a hollow stem at the top of said container, a capon said casing, an insert in said cap having a recess adapted to accommodate said stem, and a passage from said recess to the outside of said cap.

5. A pressure container structure for dispensing liquid in spray form under gas pressure comprising a substantially cylindrical container for said liquid and gas, the, upper part of said container having a restricted upwardly projecting hollow stem forming a shoulder between said, Stern and the top of said container, a cylindrical casing closely fitting said container, the length of said casing being greater than that of the container, an indentation in said casing spaced from the bottom of said casing a distance equal to the length of said container, whereby said shoulder abuts against said indentation, the material of said casing being sufliciently resilient to permit insertion and w noval of said container past said shoulder, a hollow cap, fitted over and in frictional engagement with said casing, an insert secured inside said cap and having a hollow depending neck, said stem fitting snugly in said neck, and a passage from said neck to the outside of said cap, whereby said container may be removed from said casing by first removing said cap and then pulling said container out of said casing.
