HEBMETICALLY-SEALED PACKAGE.
Application filed December 31, 1928. Serial No. 158,157.
The present invention relates to the art of sealing packages and more particularly to an improved closure cap for forming a hermetically sealed package.
5 One of the d'ifliculties encountered in forming hermetically sealed packages with metallic closure caps and glass containers, is the trapping of air in the upper part of the containers. Where packages are sealed under a vacuum, it is difiicult to exhaust the air completely with a closure cap having a gasket therein resting upon the mouth of the container and an insufficient vacuum may occasion discoloration and deterioration of the products, The trappin of air is probably most pronounced when the seal is formed on the side wall of the container by pressing a closure cap downwardly to seal the container. Theoreticall the air pressure increases inversely as t e head space, is decreased, the temperature remaining constant, For example, if the head space is two cubic inches with the cap resting on the container and one cubic inch when the cover is pressed down, the head space is halved and the pressure dou- ..bled. Thus, where no exhausting meansis used the pressure in the container is twice .the atmospheric pressure, or approximatelythirty pounds per square inch.
Theunbalanced pressure of fifteen pounds per square inch tends to force the cover off at all times. If a package sealed under these conditions is placed, in a' display window, where the sun may raise its temperature considerably, the internal pressure increases still more and the caps on manyof the packages are blown off. "Further, it is desirable to subject many products to a sterilizing heat which'likewise raises the pressure in the containers, and if an unbalanced pressure already exists in these, they cannot be subjected to high temperatures; subsequent to the sealing operation. w I Y Another difiiculty encountered with cloreformation' o the skirt of the cap isthe excessive pressure required to ap ly the caps to commercial containers. Or mary glass containers vary from a standard sizevnthin permissible ranges. Caps have to be capa- 1e of sealing tightly on a minimum size container and d tainer without creatingundpe strains in the glass. Defects in glasscontainers are {most sures sealed b downward pressure withoutand a combined edge and partial side seal were formed adjacent the mouth of the receptacle at the junction of the skirt and cover portion of the cap. Such a seal is difficult to apply due to the fact that the upper ed e of edge of the container and to prevent the cap from being seated properly on the container. Pressure 'on the skirt of the cap is at the junction ofthe skirt and cover portion and any stretching of the metal must necessarily be slight because of the reinforcing cover portion.
The present invention overcomes the above difficulties by providing a closure cap adapted torest'upon the mouth of a container and at the same time to leave passageways for exhausting air therefrom prior to the sealing operation. These passageways are not closed the gasket tends to slide over the v until the closurecap is pressed substantially the full distance downwardly over the container. The means for accomplishing this is preferably a closure cap having a gasket supported at the bottom of the skirt and a concave sealing head in the central part of the skirt adapted to engage the gasket andform an effective seal on the side wall of the container. By providing a sealing bead central- 1y of the skirt of the cap, the sealis made mainly on the said wall of the container below the rim thereof.- The sealing bead presents a narrow band of metal for engagementwith thergasket which is adapted to tates application of the cap to a container and increases the effectiveness of the seal. The part of the skirt above the bead permits the upper part of the gasket to be imbedded therein and prevents it from extending over i the rim of the receptacle and fror'minterfering with the proper application of the cap; going over a maximum size conv ing inwardly to engage the mouth of the conbrought to rest in the space between the vanes and thereafter discharged onto the floor 18. The arcuate fingers 1% permit the passage of the gases through the slots between them.
and also act as partial separating means.
I claim:
1. In .a device of the kind described, and in combination, a housing, a shaft supported in said housing, a pair of disks loosely mounted on said shaft, said disks having a plurality of apertures therein, a plurality of vanes having integral portions seated in said apertures for retaining said vanes in spaced relation to each other on said disks, said vanes being radially disposed from said shaft and having integral spaced fingers on their outer edges to permit the passage of gases therethrough, and a deflector for deflecting the gases to one side of said shaft and vanes whereby said vanes will be rotated With said disks about said shaft for arresting the movement of the heavier particles in said gases to separate said particles from the issuing gases.
2. A device as embodied in claim 1, and including a separator between each of said disks and the Walls of said housing, said separators comprising a circular dished member having integral arms bent over the periphery of said disks for rotation therewith.
In Witness whereof I aflix my signature.

ment, the indentations may be conveniently formed by unching operations and each is eflective to acilitate the escape of air.
The preferred form of gasket may be con- .veniently formed by providingdepressions in the mandrels now used as forms about which a rubber tube is telescopedfor the vulcanizing operation. The mandrel and rubber tube may be wrapped .with suitable sheeting to make the rubber tube conform to the irregular contour of the mandrel during vulcanization. The resulting vulcanized rubber tube from which the gaskets are cut will have a series of longitudinal channels, and when the gaskets are cut, these channels will form the depressed portions 11.
The cap and gasket are constructed to facilitate the mechanical assembling thereof, and to permit shipment in the assembled state so that they may be placed in automatic machines and applied to containers automatically. The sealing operation may be effected manually by pressing the cap on the container or it may be effected by suitable automatic machines. The inwardly disposed concave bead 7 being resilient and slightly smaller than the other portions of the skirt of the cap, forms a very effective seal on the side wall of the container and also securely holds the cap in its sealed position to form a seal by means of the portion of the gasket pressed against the upper portion of the skirt.
It will be seen that the present invention provides a cap which may be applied to a container without the use of expensive machinery, and that its construction is such that all air may be exhausted from the container prior to the sealing operation, and, in the event no exhaust is used, any tendency to compress the air in the head space of the container will be'relieved through the passageways formed by the irregularities in the gasket and cap. Both the cap and the gasket may be readily and inexpensively manufactured by slight modifications of existing machines, and the Ipackages formed thereby are adapted to 'wit stand the rough usage and the excessive temperature to which they may be subjected.
As various changes may be made in the above embodiment without departing from the spirit of theinvention, it'is to be understood that all matter herein set forth is to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, 1 claim:
