Definitions

  • Witchell Inventors David Bellamy, Jr.
  • a sealed bag for containing liquids typically made by a blow-molding process from a tube of molten thermoplastic resin.
  • the bag comprises a tubular body of flexible plastic, sealed at one end, and narrowing to an integral tubular neck portion at the other end.
  • a tubular recess is formed, typically in the head portion of the bag, for receiving a needle or the like for puncturing the bag to obtain the liquid contents.
  • the cross section of the bag is oval, and a hanger at one end of the bag is attached thereto at a single station to facilitate collapse of the bag as liquid is withdrawn.
  • plastic containers for liquids can be fabricated, filled, and heat sealed to enclose the liquid contents in an integrally sealed bottle or bag so that the bag can'be opened only by rupturing the plastic wall of the container.
  • the container is typically made by extruding a molten tube or parison of thermoplastic resin into a mold, and inflating the parison with air to form a container sealed by action of the mold at one end. While maintaining the container in inflated condition, a precisely metered quantity of the liquid contents are placed in the container, causing those portions thereof in contact with the liquid to solidify.
  • An open, unsealed end of the container above the liquid level remains in the molten condition after insertion of the liquid.
  • a second mold is then closed about the open, unsealed end to form a sealed neck and head portion of the container which is integral with the main tubular body thereof.
  • the finished product is thus a liquid-containing plastic bag or bottle which encloses its liquid contents in sealed plastic.
  • plastic containers for the storage and distribution of parenteral solutions, blood and other sterile products which are typically administered in measured amounts, particularly since sterility of the liquid contents can be assured until the plastic is ruptured, and also because the plastic container is inexpensive and can be thrown away after use.
  • liquids such as parenteral solutions, blood plasma, or blood in a collapsible plastic container so that, as the liquid is removed from the container, the container collapses.
  • a higher degree of sterility of the liquid can be maintained in this manner, since air, which usually carries contaminants, does not have to be vented into the container to facilitate removal of the liquid.
  • the invention of this application provides a convenient means of access to sealed plastic bags, by which sterility can be maintained while withdrawing the liquid contents. Furthermore, the plastic bag of this invention exhibits improved collapsibility, permitting the liquid contents to be readily removed from the bag without the need for venting.
  • the invention of this application relates to a collapsible bag containing a liquid and having a tubular body of flexible plastic.
  • the tubular body is closed and sealed at one end, and narrows to an integral tubular neck portion at the other end.
  • a head portion made of the same plastic is integral with the neck portion and seals the bag.
  • the bag has at least one tubular recess located at one end thereof, and typically located in the head portion, for receiving a puncturing needle or the like for puncturing the bag to obtain the liquid contents.
  • the recess is defined by a tubular sidewall and a bottom wall, the bottom wall serving as a puncturable membrane through which the needle penetrates to gain access to the liquid contents.
  • the recess contains a plastic sleeve which serves as a guide for the needle.
  • tubular body of the bag of thisinvention has sufficiently thin walls so that the tubular body lies in a generally flat, limp condition when it is not supported by the liquid which it contains.
  • the bag is generally constructed to have oval cross section when held in expanded position by its liquid contents.
  • a hanger means is attached to one end of the body at a single station or point of attachment by means of a narrow connecting neck.
  • FIG. 1 is a plan view, partly in section, of a typical plastic bag of this invention, shown to be filled with a liquid parenteral solution or the like.
  • FIG. 2 is a sectional view of the bag of FIG. 1, taken along line 2-2.
  • FIG. 3 is a sectional view of part of the bag of FIG. 1, taken along line 33.
  • FIG. 4 is a fragmentary view of the bag of FIG. 1 in which the bag has been rotated about its longitudinal axis, showing a typical integral hanger means used herein.
  • a sealed, collapsible, liquid-containing bag is generally designated at 10.
  • the bag comprises tubular body 12, made of flexible plastic, and sealed at end 14.
  • hanger 16 is formed integral with body 12, being connected thereto by narrow connecting neck 18, which is of substantially less width than hanger 16, as shown in FIG. 4.
  • Hanger 16 is attached to body 12 at a single station or point of attachment.
  • tubular body 12 narrows to an integral tubular neck 22, which, in turn, is integral with head portion 24.
  • Head portion 24 is closed to seal bag 10.
  • the liquid contents 26 of the bag are completely sealed by an integral wall of plastic.
  • FIG. 2 shows how the bag of this invention is constructed to maintain an oval cross section while filled with liquid contents.
  • the bag is not self-supporting, and collapses into a limp, generally flat configuration when not positively held in its expanded, oval configuration by the liquid contents.
  • This oval configuration facilitates the collapse of the bag to a generally flat configuration, and permits more of the liquid contents thereof to flow by gravity out of the bag without mechanical assistance.
  • FIG. 3 shows tubular recesses 26 which are formed in head portion 24; and which are of sufficient length and width to receive and hold a needle or the like for puncturing the bag to obtain the liquid contents.
  • Each recess 26 can be of any crosssectional shape desired, although the particular recesses shown are circular in cross section.
  • Recesses 26 are formed having bottom wall 28, which is punctured by the needle as it passes into the container.
  • a beveled needle having an off center point is used. The needle is inserted into recess 26 breaking through bottom wall 28 at periphery 29 with ease, peeling bottom wall 28 away about periphery 29 as the needle advances.
  • Each recess 26 may contain a tubular sleeve 30 which serves as a guide for the needle for rupturing bottom wall 28 and obtaining the liquid contents of bag 10.
  • the sleeve can be inserted into recess 26 and glued into place after bag 10 has been filled and sealed.
  • the bore of sleeve 30 is preferably proportioned so that the needle used to obtain the liquid contents fits in tight sliding relation thereto, to prevent leakage of the liquid contents when bag 10 is inverted for removing liquid.
  • a conventional seal such as a rubber cap (not shown) can be placed over each sleeve 30.
  • a conventional seal such as a rubber cap (not shown) can be placed over each sleeve 30.
  • two sleeves 30 and recesses 26 are present to provide one means of access into the bag for removing the liquid contents thereof and another means of access into the bag to add medicaments as needed to the liquid contents thereof, or to connect several bags in series so that a larger amount of liquid can be provided in one administration to the patient.
  • the means of access of the bag of this invention simply requires passing a needle through the bore ofa sleeve 30 until bottom wall 28 is ruptured. Prior to that, the interior of bag remains sterile, since it is completely sealed from the exterior. After entry of a sterile needle which fits tightly within sleeve 30, the bag is still essentially sealed so that contaminants are unlikely to enter therein.
  • tubular recesses described herein can also be used on plastic bags of circular and other nonoval cross sections, as well as with other means for hanging the bags.
  • the portion of bag 10 near head portion 24 has a generally conical configuration created by a gradual reduction of the transverse dimensions of the bag in the direction of head portion 24. This prevents the lower portion of the filled and inverted bag from bulging excessively outward by stretching due to the weight of the liquid contents. Such stretching can result in the formation of undesirable shoulder pockets in the wall about neck 18, containing trapped liquid contents.
  • the wall of bag 10 is not necessarily of uniform thickness.
  • the portions of the wall near the ends of the oval may be thinner than the portions of the wall near the sides of the oval.
  • a sealed, collapsible bag containing a liquid which bag comprises: a tubular body of flexible plastic, said tubular body being sealed at one end and narrowing at the other end to a head portion integral with said tubular body for sealing said bag, and a tubular recess at one end of said collapsible bag, said tubular recess being defined by a tubular sidewall of essentially uniform transverse dimension and a bottom wall, said walls being integral with the remaining material of said bag, said recess containing a tubular sleeve for receiving and holding means for puncturing the bag to obtain said liquid.
  • tubular recess In a sealed, collapsible bag containing a liquid, a tubular recess, said tubular recess being defined by a tubular sidewall of essentially uniform transverse dimension and a bottom wall, said walls being integral with the remaining material of said bag, said recess containing a tubular sleeve for receiving and holding means for puncturing the bag to obtain said liquid.
