ABSTRACT: The cover for a gastight container for a breathing apparatus has formed in one piece therewith a tearaway tongue which when pulled off leaves a hole through the cover.
TEARAWAY TONGUE FOR GASTIGHT CONTAINER This invention relates to a tearaway tongue for a gastight container and is an improvement upon the structure disclosed in my copending application Ser. No. 632,602, filed 21 April I967, for Gastight Container, now Pat. No. 3,487,973. Said copending application discloses a gastight container for holding under less that than atmospheric pressure a breathing apparatus and especially a breathing apparatus having a moisture sensitive filter medium. The container is composed of a lower container portion and a cover for closing the same. As the interior of the container is under less than atmospheric pressure, the cover and container portion are sealed airtight to one another by means of the outside-atmospheric pressure alone. One part of the container is-provided with a manually actuated device to form an opening to equalize the inside and outside pressures. The part of the container to be opened by this device is a breaking point indentation or the like. Also, the
.wall of the container can be recessed within the area of that opening point for the equalization of pressure.
The object of this invention is to improve upon the structure of my aforesaid application.
In general, this object is obtained by connecting the breaking point part on the outside of the-container with the end of a tearaway tongue.
The means by which the objects of this invention are obtained are described more fully with reference to the accompanying schematic drawings in which:
FIG. 1 is afront view of the container, partly shown in sectrons;
FIG. 2 is a cross-sectional view through the cover for the container; 1.
FIG. 3 is a plan view of FIG. 2; and I FIG. 4 is a cross-sectional view taken on the line 4-4 in FIG. 2.
As shown in FIG. I, the airtight container is composed of a lower container portion 1 made of sheet metal or extruded synthetic resin and has a removable cover portion 2 composed of the same material. The abutting edges 3 and 4 form the upper edge of portion 1 and the lower edge of portion 2, respectively. A sealing ring 5 is mounted between these edges. The breathing bag 6 is placed within the container.
The cover 2 in this invention is produced by injection mold- The cover 2 has a recessed channel 50 extending across its top and within which is mounted the device for producing the opening to equalize the pressure within the container when the container is to be opened.
This device is composed of a tearaway tongue 51 which in nonnal position, as shown, does not extend beyond the outside profile of the cover, that is the surface 52 of the cover. The tongue 51 has its free or forward end 53 turned slightly upwardly and spaced from the cover in order to enable it to be easily grasped by the fingers of the person opening the container. Tongue 51 has a thickened rear end 54 which is formed in one piece with the bottom wall 55 of channel 50. Bottom wall 55 has a recess 56 extending from the interior of the container and which goes beyond the surface plane 57 of the bottom wall 55 and thus extends into the thickened end 54 of the tongue. A relatively thin-walled circumferential joint line 58 is thus formed between the thickened end 54 and the bottom wall 55, which line lies approximately in the outer surface plane 57 on the tongue side of thickened end 54.
The tongue 51 and the cover 2 are produced in one and the same injection molding so that they form a single piece.
When tongue 51 is pulled upwardly,.the tongue is torn off along the line 58 so that an opening is formed through the cover to equalize the air pressure within and without the container.
For ease of handling, tongue 51 can be given a ribbed or corrugated surface.
Having now described the means by which the objects of this invention are obtained,
I claim: 1. An airtight container for a breathing apparatus and especially for an apparatus having a moisture sensitive filter medium comprising a lower container portion, and an upper cover, airtight sealing means joining'said container portion to said cover, a tongue (51) having a thickened rear end (54) joined to said cover, said tongue and cover being of a single piece of the same material, a recess (56) in the inner surface of said cover and extending beyond the outer surface (55) of said cover into said thickened rear end for defining a breaking line (58) approximately in the plane (57) on the tongue side of said thickened end (54).
2. A container as in claim 1, said outer surface being the bottom of a channel (50) in said cover, and said tongue being mounted entirely within said channel.
Claims (2)

An airtight container for a breathing apparatus and especially for an apparatus having a moisture sensitive filter medium comprising a lower container portion, and an upper cover, airtight sealing means joining said container portion to said cover, a tongue (51) having a thickened rear end (54) joined to said cover, said tongue and cover being of a single piece of the same material, a recess (56) in the inner surface of said cover and extending beyond the outer surface (55) of said cover into said thickened rear end for defining a breaking line (58) approximately in the plane (57) on the tongue side of said thickened end (54).
2. A container as in claim 1, said outer surface being the bottom of a channel (50) in said cover, and said tongue being mounted entirely within said channel.
