PACKAGING MEANS FOR'ARTICLES THAT ARE DELETERIOUSLY AFFECTED BY MOISTURE Filed May 19, 1958 5 a Y 3 L 10 INVENTOR. EDWIN V BISHOP 7157.3 wa a/ ATTORNEYS v PACKAGING MEANS FOR ARTICLES THAT ARE DELETERIOUSLY AFFECTED BY MOISTURE Edwin V. Bishop, Sparks, Md., assignor to Kirwan Y. Messick, Smithfield, Va.
Application May 19, 1958, Serial No. 736,220
2 Claims. (Cl. 220-85) This invention relates to packaging means for materials or articles that are deleteriously affected by moisture and its object is to provide a novel type of package comprising very simple and inexpensive means for converting certain well known commercial forms of containers into containers in which the internal pressure is maintained substantially constant.
It has heretofore been proposed to provide a container having therein a flexible or elastic bladder the interior of which is in communication with the external atmosphere. A rise of pressure outside the container, instead of causing outside air to seek entry to the container through any minute leaks which may exist, merely expands the bladder, while a drop in the external atmospheric pressure merely results in contraction of the bladder, the result in each case being to maintain equal pressure both within and outside the container, irrespective of fluctuations of pressure within the container if the latter be subjected to wide variations of heat or cold.
The device of the present invention is adapted to accomplish the foregoing objects in conjunction with containers of the type Widely used to receive roll materials, such as drawings, prints, pictures and the like. The containers usually employed for the storage of many types of such materials are often in the form of elongated cardboard tubes of the mailing tube type. Many of the papers, such as drawings and prints, which have to be stored are quite valuable, including many highly secret or classified drawings, prints and tracings of drawings, photostatic prints and Ozalid prints. Many of these are highly sensitive to moisture and may be caused to fade or otherwise deteriorate if subjected to moist atmospheric conditions for any appreciable length of time. The serious losses which could arise from the destruction, fading or damage of drawings, prints or like valuable documents has caused the government to establish rigid requirements concerning the storage of the same. In many cases it is required that the containers be stored in rooms in which both the temperature and pressure are controlled and made continuously uniform within very close tolerances at all times. This has involved very great expense in the provision of rooms or buildings adapted to carry out these rigid requirements.
This invention aims to provide individual tube-like containers adapted to receive roll materials of the character indicated, together with a simple and inexpensive pressure equalizing capsule, of a nature to be received within the conventional paper cap or closure of such a tube and means for assembling the capsule and closure in such a simple and inexpensive manner that the desired individualized containers may be furnished to the user at a cost of only a few cents.
The manner in which the foregoing object is carried out is illustrated in the accompanying drawing, wherein:
Fig. 1 'is a side elevation of the complete package of the invention;
Fig. 2 is a greatly enlarged, longitudinal sectional view through the removable cap end of the package; and
Patented Nov. 10, 1959 Fig. 3 is a transverse sectional view on line 3-3 of Fig. 2
Like numerals designate corresponding parts throughout the drawing.
The conventional paper storage tubes now so largely employed comprise an elongated cylindrical body 5, the bottom or rear end of which is closed, air tight, by a metallic 'cap 6. At the receiving end the tube 5 is re-.
duced in thickness for a short distance as at 5 and a closure cap C slides upon this reduced portion to eifect a closing of the package, after a roll of papers or other articles to be stored have been placed therein. The described reduction in thickness may be effected by making the body 5 to consist of an inner thickness 5 and an outer thickness 5 with the portion 5 projecting beyond the portion 5 The conventional closure caps comprise a cylinder '7, usually of paper, the outer end of which has a metal plate or end 8 crimped forcibly thereon in manufacture. The parts are so constructed that when the cap C is slid along the portion of reduced thickness 5 the closure is substantially air tight.
The capsule constituting the pressure equalizing element of the invention consists of a simple paper, cardboard-like cylinder 10 the inner end of which is closed by a metallic cup-like head 11, except for an opening 12 formed in head 11. A plastic bag 13, constituting an expansible and contractable bladder is disposed in cylinder 10 and the material of this bag is turned over the outer end of cylinder 10 and inwardly along the outside of the cylinder as at 14, where it makes air tight engagement with the cylinder. The material of the bag being of an elastic, rubber-like plastic, such as neoprene .for
7 example, hugs the cylinder so forcibly at its inturned portion 14 that the necessary air tight engagement of such portion with cylinder 10 is had. However, this inturned portion 14 may be cemented to the cylinder in addition, if desired.
A metallic closure of cup-like formation comprises the flat end plate 15 and an inturned flange 16, which flange embraces the inturned portion 14 of the plastic bag or bladder when the closure is forced upon the cylinder 10. Openings 17 in plate 15 and openings 18 in end plate 8 of the closure cap C bring the interior of the bladder into communication with the external atmosphere.
In assembling the capsule and closure C the plate 8 is placed in a horizontal position and a ring of a plastic sealing material 19, is run around and upon plate 8. Then the flat end plate 15 of the capsule is pressed forcibly toward the flat end plate 8 of the closure cap and against the annulus of plastic sealing composition, until the sealing composition sets and securely unites capsule and cap.
Many types of sealing compositions are available. A
plastic of the general consistency of that used in laying linoleum has been found to be suitable. The sealing composition should be capable of hardening to a stiff and substantially solid consistency but not to the point of such brittleness as would make it susceptible to easily breaking loose upon shock or jar of the package.
It will be understood that the capsule is thereafter and by the material 19 united with and is carried by the closure cap, to be automatically positioned in protective position with respect to the contents of the package by the mere act of sliding the closure cap into position and without the necessity of tightening fastenings of any nature whatever. The described structure adds so little to the conventional closure cap that the cost is almost negligible.
If desired a small piece of silica gel or like moisture absorbent may be dropped into the main container 5 before the cap C is placed in position. Thereafter the a '3 automatic breathing of the capsule keeps moisture laden atmosphere excluded for any desired length of time.
It is understood that the invention is not limited to the particular construction illustrated and describedbut that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.
I claim:
l. A storage receptacle comprising an elongated main tubular paper board body portion closed atone end and open at the other, a main closure cap having a slidable movement upon the outer end portion of the main body and constructed to be substantially air tight when forced upon said main body, said cap comprising a metallic end plate, a capsule within the main cap comprising a cylindrical body and an outer end closure plate which lies in substantial parallelism with the end plate of the main closure cap, an annulus of adhesive lying between and uniting the end closure plane of the capsule with the end plate of the main closure cap; an elastic air tight bladder forming bag within the cylindrical body having its outer edge portions turned over the end of the cylindrical body of the capsule there being openings formed through the end plateof the main cap and the closure plate of the capsule to permit the passage of air through the interior portion of the adhesive annulus from the atmosphere to the interior of said bladder forming bag.
2. A structure of the character described comprising an elongated tubular main body receptacle, and a main closure cap slidable endwise upon the receptacle at the entrance end thereof which includes an outer end wall, a capsule within and carried by the closure cap comprising a cylindrical body, a compressible and expandable portion of the interior of the cylindrical body which lies 4 bladder within said cylindrical body in the form of a plastic bag the outer edge portions of which are disposed toward and have air tight engagement with the outer end portion of the cylindrical body, a cup-like metallic closure comprising a flat plate which lies in parallelism with the outer end wall of the main closure cap, which closure has air tight engagement upon the outer end of the cylindrical body and air tight adhesive sealing means disposed between and uniting the flat plate of the closure of the cylindrical body with the inner face of the end wall of the main closure cap through an annular path which surrounds but does not cover the central portions of said fiat plate and end wall, and openings in the central portions of the fiat plate and in the end wall of the main closure cap for permitting the passage of air through said plate and the said end Wall of the closure cap, to thereby establish communication between the interior of the bladder and the external atmosphere, the surrounding sealing adhesive preventing air from passing to the interior of the main body receptacle, there being an opening in the capsule through which communication is estab-' lished between the interior of the main body and that outside the plastic bag.
