Description
7~2 Background of the Invention The present invention relates to disposable sterilizable pouches used in medical facilities to sterilize articles used to care for patients. More particularly the present invention is directed to a pouch that is easy to use, self sealing and maintains a contaminant proof seal after sterilization.
In recent years there has been substantial promotion of the use of disposable pouches such as shown in United States patents 3,604,616; 3,819,106; and 3,420,433. There has also been development of self-sealing envelopes such as illustrated in patent No. 3,070,280. However, the development did not meet all the requirements of the medical field. Surprisingly a self-sealing pouch has now been developed that is convenient to use, economical, does not require special heat sealing equipment or hand tape application, which remains contaminant proof for long time periods and which also indicates if the seal has been tampered with or broken.
Summary of the Invention A sterilizable pouch comprising a first web of thermally stable transparent film and a second web of steam permeable paper sealed together to form a pocket unsealed at one end. One of the webs extends beyond the unsealed end edge of the other web to form a flap. Sealing means are disposed adjacent to and spaced from the unsealed end edge of the other of the webs across the entire width of the web, thereby defining an adhesive free zone between the sealing means and the unsealed end edge of the other of the webs.
The sealing means have sufficient width to permit sealing of both (a) the adhesive free zone on the web which carries

Detailed Description of the Inv ntio While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illl~strated.
Pouches according to the present invention suitably comprise two opposing webs. Web 10 is preferahly a transparent thermally stable material such as coated or laminated polyethylene terephthalate (Mylar). Web 10 is sealed to opposing web 11 by heat seal 12. Web 11 is preferably made of a steam permeable paper to permit the pouch to undergo autoclave sterilization.
In a pouch of generally rectangular configuration the seal along respective pouch sides 13 and 14 is suitably a * Trade Mark ~14770Z
straight line along the side edges. ~ottom seal portion 15 may be chevron shaped leaving the webs unsealed in pouch area 16 to provide gripping means as is illustrated in Fig. 2-The chevron shaped seal and gripping means cooperate to permit easy opening of the pouch.
Adhesive means 17 may be applied across the surface of web 11 to a portion of flap area 18 as shown in Fig. 1.
The adhesive means is preferably a pressure sensitive adhesive which will be more fully discussed below. The positioning of the adhesive is of critical importance to the invention.
In the embodiment shown in Fig. 1 the adhesive is spaced a distance y from upper unsealed lip 19 of web 10. The distance y the adhesive is spaced from lip 19 and the width x of the pressure sensitive adhesive are suitably related so that the width of the adhesive is broad enough to cover an area adjacent each side of lip 19 to form a continuous seal to prevent contamination of the contents of the pouch after sterilization. It has been found preferable to use an adhesive width x of about 3/4 of an inch when the distance of space y is about 3/8 of an inch. Thus, when the flap is closed the adhesive covers equal areas of 3/8 of an inch on either side of lip 19. It should be appreciated that distance y that the adhesive is spaced from lip 19 may vary from about 3/8 of an inch to 1/2 inch or more. Similarly width ~ of the adhesive may also vary from about 3/4 of an inch to one inch or more provided that the relationship of distance y and adhesive width is sufficient to maintain a contaminant proof seal.
The adhesive of the invention is suitably a pressure sensitive adhesive that permits the pouch to self seal upon closing and the application of pressure along the adhesive area, 11~77~2 Pressure sensitive transfer tape or double coated pressure sensitive transfer tape may be used in the invention.
The selection of the pressure sensitive adhesive is of par-ticular importance. The adhesive selected should be formulated from materials meeting Food and Drug Administration requirements for adhesives under FDA Section 121.2520.
Suitably the adhesive selected should give bonds that maintain contaminant proof integrity from -30F. to +350F. Pressure sensitive adhesive tapes are normally provided with release liners which has not been shown on the drawing.
The adhesive of the invention should also be selected to provide sufficient holding strength to the paper web to tear at least a portion of the web if the closure at the pressure sensitive seal is opened. In this manner a telltale is provided to give a clear warning that the pouch has been opened and the sterile seal has been broken. This will avoid accidental resealing of a sterilized pouch.
The bond strength of the adhesive should be minimally strong enough to cause fiber tear of the paper web whereby paper fibers visibly stick to the adhesive. It is also suitable for the pressure sensitive adhesive to bond with sufficient strength to the paper that the paper web is caused to tear when the pressure sensitive closure is opened.
Illustrative performance date for the pressure sensitive adhesive is a peel strength according to PSTC-3 of 30 minutes dwell 40 oz./in, and a 24 hour dwell 50 oz./in.
A shear strength of 165 hours pursuant to PSTC-7 for 1,000 gm at room temperature.
The embodiment of Fig. 2 shows the invention illustrated in Fig. 1 in a closed position.
The closure of Fig. 2 is obtained by folding flap 18 along the fold line generally defined by edge 20 the adhesive edge nearest lip 19. The flap is folded over which essentially seals paper web 11 to itself and to the area on web 10 as is illustrated in Fig. 3.
An alternative embodiment of the invention is illustrated in Fig. 4 which shows the pressure sensitive adhesive strip disposed on the surface of web 10. As pre-viosly explained, the web is spaced a distance y from lip 19 and the distance of space Y and the width x of the adhesive are cooperatively selected to provide a contaminant proof seal.
The closure of Fig. 4 is made by folding along a fold line generally defined by the edge of adhesive nearest lip 19. The closed pouch of Fig. 4 is shown in Fig. 5 and as may be seen the film of web 10 is sealed to itself and to the flap of web 11 to form a contaminant proof seal.
While preferred embodiment have been shown and described, it will be appreciated that other modifications may be made without departing from the spirit of the invention.
For example thermally stable films other than Mylar such as nylon may be used. The thermally stable films may be coated with materials in order to permit the thermally stable film to be heat sealed to the opposing web.
It is also possible to use the present invention for gas sterilized pouches and for radiation sterilized medical pouches~
