Int. Cl. A613' 1/06il365d 83/ 00 s ABSTRACT F THE DISCLOSURE A liexible ampoule for storing medicaments and the like. The ampoule comprises an outer envelope and an inner envelope, and an antioxidant or antiseptic material may be dispersed therebetween. The outer envelope is formed of a pair of relatively non-elastic films which are heat sealed together along their edges. The inner envelope includes a gusset along one edge thereof formed by folding the inner envelope along spaced parallel lines. The other edges of the inner envelope are heat se'aled together between the associated heat-sealed edges of the outer envelope.
RELATED APPLICATION This application is a continuation-in-part of my prior co-pending application entitled Liquid Container and Method, Ser. No. 405,551, filed Oct. 21, 1964, now abandoned.
BACKGROUND OF THE INVENTION This invention relates to a liquid-filled container, and nds particular utility in medicinal use. It is known that individual doses of Amedication to be injected are divided into small glass ampoules. However, handling, washing, filling and labeling of the ampoules are considered complicated and expensive operations. There is also a need for a container in which small quantities of medicine in powdered form, such as antibiotics, can be stored, diluted, and withdrawn without exposing the solution to air. Rubbercapped antibiotic flasks now in use have proved to be unsatisfactory for this use.
SUMMARY OF THE INVENTION The inventive ampoule stores a measured quantity of medicament and permits easy withdrawal of the medicament when it is to be administered. The heat sealed edge of the outer envelope which is adjacent the gusset of the inner envelope may be readily torn olf to expose the gusset. The sides of the gusset serve to guide a hypodermic syringe and facilitates perforation of the inner envelope by the syringe. After the medicament is withdrawn, the relatively inexpensive ampoule may be discarded.
DESCRIPTION OF THE DRAWING FIG. 1 is an elevational view of the inventive ampoule;
FIG. 2 is a view similar to FIG. 1 showing the contents of the ampoue being withdrawn;
FIG. 3 is a sectional view taken along the line 3--3 0f FIG. l; and
FIG. 4 is a fragmentary sectional view showing the contents ofthe ampoule being withdrawn.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIGS. 1 and 3, the numeral 10 designates -generally the inventive ampoule, which may advantageously be formed according to the method described in my co-pending application entitled Method of Forming Flexible Ampoules, Ser. No. 636,830, filed May 8, 1967.
3,474,789 A PatentedvOct-UZS, 1969 IICC , Ampoule is seen to be generally rectangular in shape t Ul Derivatives of the phenol group such as hexylresorcin hav been found particularly suitable.
Outer envelope 11 is advantageouslyl formed of a pair of films 14 and 15 of a relatively non-elastic material which is relatively impervious to oxygen and moisture such as ethyl vinyl acetate, polyvinylidene chloride (saran), or the like. It is desirable that at least one of the films 14 or 15 be transparent in order to permit visual observation of the contents of the ampoule. However, one of the ilms may be of metallic foil or other opaque material which provides better protection for the inner envelope. The edges of the lms 14 and 15 are heat sealed together as at 16, 17, 18, and 9.
When it is desired to withdraw the contents of the ampoule, the nurse or physician tears the outer envelope along the seal 19, thereby exposing the gusset 20 of the inner envelope. A needle 25 of a hypodermic syringe 26 may then perforate the inner envelope along the fold 22 of the gusset. The gusset guides the syringe and facilitates perforation of the inner envelope. The unequal sides of the gusset facilitate insertion of the syringe between the gusset sides, and the shorter gusset side providing by the fold 21 may be more readily observable by imprinting thereon a line 27.
When the lm 12 is an antiseptic, the gusset 20 becomes coated with the antiseptic and the needle of the syringe is lubricated with the antiseptic as it passes through the gusset, thereby preserving the aseptic qualities of the arnpoule contents.
The inventive ampoule permits ready insertion of the syringe when it is iilled with either a liquid or a powdered medicament. The ampoule may be used to store a small quantity of medicine in a powdered form, such as an antibiotic. The medicine can be diluted in the ampoule by injection of a solvent through the syringe, and when the powder is dissolved, the solution can be aspirated by the syringe. The ampoule thereby allows antibiotics to be prepared for use without the introduction of air, which cannot be done with antibiotic asks provided with rubber caps currently being used.
While in the foregoing specifications, detailed description of the preferred embodiment was set down for the purpose of explanation, many variations of the details herein given may be made by those skilled in the art Without departing from the spirit and scope of the invention.
I claim:
1. A flexible container of generally rectangular shape comprising an outer envelope and an inner envelope, said outer envelope formed by a pair of films, said films being heat sealed along the edges thereof, said inner envelope being disposed within the outer envelope and being folded on itself along spaced parallel lines to develop a gusset along one edge, the other edges of said inner envelope being heat sealed between associated edges of said films.
2. The container of claim 1 in which an antioxidant is dispersed between said inner and outer envelopes.
3. The container of claim 1 in which an antiseptic is dispersed between said inner and outer envelopes.
4. The container of claim 1 in which said gusset is developed by three reverse folds of said inner envelope to form a pair of gusset sides, said sides being of unequal length.
. .14v Y 5. The container of claim 1 in which said films are relatively non-elastic.
