BOTTLE CAP Filed July 23, 1956 Inventor G's/v0 SAcca/M A I/a orneg/ United States Patent F BOTTLE CAP Geno Saccomanno, Grand Junction, Colo. 7 Application July 23, 1956, Serial No. 599,466 6 Claims. (Cl. 215-48) The subject matter of this invention relates to a bottle cap containing therein an isolated receptacle chamber with I provisions for simultaneous filling of the said receptacle chamber and the contents of the bottle.
In particular such a bottle cap can be used inconjunction with a blood bottle. Pilot tubes containing a sample of the blood contained in the permanent container are in widespread use. The function of the pilot tube is to provide a sampling source to test compatability between the donors blood and the'blood of the recipient. By this means of sampling, no risk of contaminationis Patented Nov. 3, 1 959 ice to be within the chamber of the cap when the needle is fully inserted. One of the openings allows a portion of the liquid flowing through the needle 'to enter the isolated chamber and the other opening allows escape of the air from the chamber when it is being filled with liquid. Thus, both the bottle and the isolated receptacle'within the bottle cap-are simultaneously filled.
After filling has been completed the hypodermic needle can be removed, thus isolating the fluid sample through the action of the self-sealing closure.
The device of Figures 1 and 2 comprises a bottle cap 1 made of rubber or similar self-sealing resilient material whose dimensions can be so selected as to snugly fit into any chosen bottle 2. The bottle cap 1 contains an outlet tube 3 and an air vent tube 4 so the contents of the bottle 2 may be emptied without removing the bottle cap 1.
Within the bottle cap 1 is an isolated receptacle chamber 5 with the walls 6 thereof lined with silicone or similar material which serves to adapt the receptacle chamber 5 to receive and store fluids more efliciently.
The isolated receptacle chamber 5, in effect, isa hollowed portion of the bottle cap 1, thus, naturally proincurrcd'as it would be by-removing a sample from the permanent container. 1
Since previous procedures involve separate filling of the permanent container and the pilot tube container, an unavoidable risk of human error in handling is involved. It is imperative that both the pilot tube and the bottle have the same blood from any one donor; It has been necessary to rely on the meticulous care of the operator to attach the correct pilot tube to each blood bottle. Such handling can never be free from the possibility of error, and an error may have tragic consequences.
The principal object of this invention is to provide a bottle cap which precludes any possibility of the contents of the bottle being different from the contents in the sampling receptacle.
Another object of this invention is to provide a convenient and simple means whereby an isolated chamber within a bottle cap,- and the bottle, maybe filled in one operation.
These and other objects and advantages will beunderstood by reference to the detailed description and theaccompanying drawing in which there is illustrated a selected embodiment of the bottle cap.
In the drawing: v I
Figure 1 is a top view of the bottle cap showing the relative positions of the receptacle chamber, the inlet tube and the air vent tube;
Figure 2 is vertical sectional view taken along the lines 2 2 of Figure 1; Figure 3 is'a vertical sectional view showing a modific-ation of the isolated receptacle chamber whereby the top cover can be removed;
Figure 4 is a top view showing a modification in which the inlet and air vent tubes are eliminated;
Figure 5 is a longitudinal sectional view of a needle for use in filling the blood container and pilot sample cap.
in the accomplishment of the foregoing objects and in accordance with the invention there is now provided a bottle'cap which serves the dual function of a sealing cap for the opening of a bottle, and as an isolated receptacle chamber to simultaneously collect a sample of the fluid introduced into the bottle. The sealed cap has penetrable closures. at each end so that a hypodermic needle may be inserted. through bothclosures, thus conveying a supply of fluid from an outside source to the interior of the bottle. The shank of the needle has two openings adapted viding circular sidewalls 6 and a bottom for the receptacle'chamber 5. The receptacle chamber 5 is completely isolated'by placing a hard nylonreceptacle cap 9 snugly into a groove or indentation 11 located in the circular wall 6 of the receptacle chamber 5. The center of the receptacle cap 9 is provided with a circular diaphragm 10 made of rubber or other equivalent penetrable, self-sealing material. This diaphragm should be at least 4 mm. in thickness to assure self-sealing after removal'of a hypodermic needle.
The receptacle cap 9 can be made of hard material equivalent to nylon which is designed to withstand conditions of sterilization in the event such treatment is desired. The resting position of the receptacle cap 9 is at i a point below the top of the bottle 2 so that the pressure from the sides of the bottle 2 top may be directed toenhance the tight fit of the receptacle cap 9 in the indentation 11 in the circular margin of the receptacle wall 6.
In order to fill the bottle 2 and the receptacle chamber 5 a specially prepared hypodermic needle 8 is inserted through the penetrable diaphragm 10 in the receptacle cap 9, into the receptacle chamber 5 and then through the penetrable floor of the receptacle chamber 5 so that the tip of the needle 8 extends into the interior of thebottle 2. j
The needle 8 has specially adapted openings 12 and 13 in its shank. The length of the needle 8 is so selected,
and the positioning of the openings 12 and 13 is so arranged that when the needle 8 is fully inserted the openings 12 and 13 in the shank are .located in the upper portion of the receptacle 5 and the tip of the needle 8 extends into the interior of the bottle 2. The fully inserte position of the needle 8 isdepicted in Figure 2. p Liquid such as blood from an outside source is directed into the bottle 2 by way of the needle 8 at which time simultaneous filling of the receptacle chamber 5 and bottle 2 occurs. This function will be more fully vdeveloped laterin conjunction with Figure 5.
ber 5 for later sampling may be accomplished by insert ing vthe needle of a hypodermic syringe through the penetrable self-sealing diaphragm 10 in the receptacle cap 9 in Figure 2 and withdrawing the desired volume of sample fluid into the syringe.
Figure 1 is a top' view showing the relative positions of the receptacle chamber 5, the receptacle cap 9 and the penetrable diaphragm 10. These aforementioned structures are placed eccentrically in the bottle cap 1 to allow space for insertion of the conventional outlet tube 3 and the air vent tube 4.
Figure 4 is a modification of the top view of Figure 1 in which'the receptacle cap 9 and the underlying receptacle chamber 5 are located centrally in the bottle cap 1. The air vent 4 and outlet tube 3 have been eliminated. This modification is provided in the event removal of the bottle cap 1 prior to'emptying the contents of the bottle 2 is desired.
Figure 3 is a vertical sectional view showing a modifi: cation of the receptacle cap whereby the cap can be removed for withdrawal of the fluid sample from the chamber 5. The receptacle cap 15 is fitted to the walls 6 of. the bottle cap 1 by means of a threaded junction or by means of a friction contact. Ribbed elevations 14 are provided on the top of the receptacle .cap 15 for grasping in removing the said receptacle cap 15.
Surrounding the isolated receptacle chamber 5 is a metal cup or,other hard support 7 which is designed to prevent collapse or other distortion of the receptacle chamber 5 when the bottle cap 1 is forced into the opening of the bottle '2. Such a metal cup is provided with an opening in its bottom to allow passage of a hypodermic needle 8 through the bottomiof' the bottlecap 1 into the interior of the bottle 2. I
Figure 5 is a longitudinal sectional view of the needle 8 :showing the relative positions of the openings in the shank of said needle 8. A flanged opening 12 is situated below a round opening 13. When fluid from an outside source is directed through the needle 8, a portion of the fluid escapes through the flanged opening 12 into the receptacle chamber 5. As fluid accumulates in the receptacle chamber 5 the increased air pressure escapes through the round opening 13 into the interior of the bottle 2. After the receptacle chamber 5 is filled with fluid, the bottle 2 continues to fill to its desired volume.
.From the foregoing detailed descriptions it can be readily seen that this device shows particular utility in the use .of conventional blood donor units, however, it should be understood that the principle of the present invention can be incorporated in any procedure demanding separate isolation of a fluid sample of the same nature asthat contained in the larger container or receptacle.
Others may practice the invention in any of the numerous ways which will be suggested to one skilled in the art upon a reading of this specification. It is intended that all such practice of' the invention be included hereunder provided it falls within the scope of the appended claims.
