Description

BACKGROUND OF THE INVENTION

Success rates with respect to action taken in response to an emergency situation almost always improve with proper preparation, access to the proper equipment, and speed. This could not be more true than in the case of providing a dose of fluid (e.g., epinephrine to a patient experiencing a severe or life-threatening allergic reaction (anaphylaxis)). According to the National Institute of Allergy and Infectious Diseases, early treatment with epinephrine is beneficial to patients having an anaphylactic episode because the patient could experience a rapid decline in health or death within 30 to 60 minutes. Such early treatment may also be beneficial in patients experiencing seizure activity.

In addition to quick administration of treatment, accurate dosing is crucial because not enough medicine may be ineffective and too much may cause health risks, such as dangerously high blood pressure, stroke, or death. During an anaphylactic event, for example, a health provider may need a larger or smaller dose depending on the size or age of the patient and fumbling with a vial and a needle may add precious seconds before treatment and potential dosing errors.

Further, sterilization is important whenever it comes to administering a drug to a patient through a needle and a health care provider has to know if the needle being used and the drug being administered have not been tampered with. Accordingly, the art of emergency treatment could benefit from a device that promotes quick access to a drug applicator which may be stored in pre-set doses and provides evidence of tampering.

SUMMARY OF THE INVENTION

The present invention relates to a closure container, and more particularly to a container that can house a preset drug applicator in an easily accessible manner with tamper evidencing means.

According to an aspect of a system according to the present invention, such system may include a first casing member and a second casing member, configured to cradle a syringe containing a predetermined amount of fluid. The container further includes a fastener having a tamper-evident pull-tab, the fastener being connected to one of the first casing member and the second casing member and configured to releasably maintain closure of the container. The container may be formed as a unitary injection-molded piece with the first casing member and second casing member hingedly connected by a living hinge.

According to yet another aspect of a tamper evident closure container according to the present invention, the fastener may depend from the first casing member and include a barb, which is receivable in a slot formed in the second casing member.

According to yet a further aspect of a system according to the present invention, a window surface may be formed on one of the first casing member and the second casing member, wherein the window is formed on the first casing member by masking a window portion of the first casing member with a mask material, surface treating at least a portion of each of the first casing member and the second casing member, and removing the mask material from the window portion. The window surface may be positioned on the container to enable visual access to a barrel of a retained syringe.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structures. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.

Turning first to FIG. 1, a first embodiment 10 of a closure container according to the present invention is shown. The closure container 10 preferably comprises a single injection-molded piece having a first casing member 100 hingedly attached to a second casing member 200 by at least one hinge 12 (see FIG. 2), which may be a living hinge.

The first casing member 100 may generally be formed along a longitudinal length between and including a first end 102 opposite a second end 104, an outer surface 106, a peripheral edge portion 116 (FIG. 2), a fastener 118, and an inner surface 132 (FIG. 2).

The outer surface 106 of the first casing member 100 extends from the first end 102 to the second end 104 and to the peripheral edge portion 116. The outer surface 106 has a planar portion 108 with a window 110 preferably provided therein and a plurality of catches 112 projecting therefrom.

Each catch 112 preferably has an L-shape profile and extends outward from the planar portion 108, whereby an arm 114 of the L-shape is spaced from and substantially parallel with the planar portion 108 of the outer surface 106, and all of the catches 112 are oriented preferably in the same direction.

The fastener 118 is flexibly connected at or near the peripheral edge portion 116 of the first casing member 100 opposite the hinge 12. The fastener 118 has a width 120, a thickness 122, an exterior surface 124, an interior surface 126, and a tamper-evident pull-tab 130. A barb 128 projects from the interior surface 126 distal to the outer surface 106 of the first casing member 100.

The tamper-evident pull-tab 130 preferably extends substantially perpendicular from the fastener 118 between the barb 128 and the outer surface 106 of the first casing member 100. The tamper-evident pull-tab 130 is preferably offset from the exterior surface 124 of the fastener 118 in a direction away from the container 10 when the fastener 118 is in an engaged position, as discussed further below.

The inner surface 132 of the first casing member 100 can be seen in FIGS. 2 and 3. The inner surface 132 extends from the first end 102 to the second end 104 and to the peripheral edge portion 116, and preferably has an at least substantially planar portion 134. As shown here, a bridge 136 with a notch 138 projects from the planar portion 134 of the inner surface 132 near the first end 102 to or near the peripheral edge portion 116.

A retainer 140 extends from the planar surface 134 to or near the peripheral edge portion 116 and comprises a first wall 142, with a first wall notch 144, and a second wall 146, with a second wall notch 148, substantially parallel to the first wall 142.

A plurality of dosing ribs 152 project from the planar portion 134 to or near the peripheral edge portion 116 and are spaced between the second end 104 and the second wall 146 of the retainer 140. Each dosing rib 152 has a notch 154, an innermost side 156 (hidden), and an outermost side 158. The spacing between the dosing ribs 152 relates to the predetermined dosage provided in a syringe 50 (FIG. 2) to be contained within the closure container 10. The preferable dosing amounts for which the ribs 152 will be spaced are 0.25 mL, 0.5 mL, 0.75 mL, and 1.0 mL, but other dosing amounts are contemplated.

The second casing member 200 may be seen in FIGS. 2 and 3 as well. The second casing member 200 has a first end 202 opposite a second end 204, an outer surface 206, a peripheral edge portion 216, and an inner surface 232.

The outer surface 206 of the second casing member 200 extends from the first end 202 to the second end 204 and to the peripheral edge portion 216. The outer surface 206 preferably has an at least substantially planar portion 208 with a plurality of holes 260 (FIG. 5) therein which are sized, positioned, and configured to be mateable with the catches 112 of the first casing member 100 of another closure container 10.

As shown in FIGS. 10 and 11, the outer surface 206 of the second casing member 200 has a recess 262 with a width 264 slightly greater than the width 120 of the fastener 118 and a depth 266 preferably similar to the thickness 122 of the fastener 118. A slot 268 sized and configured to receive the barb 128 of the fastener 118 is provided within the recess 268.

Looking back to FIGS. 2 and 3, the inside surface 232 of the second casing member 200 is shown. The inside surface 232 of the second casing member 200 is preferably substantially similar to the inside surface 132 of the first casing member 100. As shown here, the inner surface 232 extends from the first end 202 to the second end 204 and to the peripheral edge portion 216, and preferably has a planar portion 234. As shown here, a bridge 236 with a notch 238 projects from the planar portion 234 of the inner surface 232 near the first end 202 to or near the peripheral edge portion 216.

A retainer 240 extends from the planar portion 208 to or near the peripheral edge portion 216 and comprises a first wall 242, with a first wall notch 244, and a second wall 246, with a second wall notch 248, substantially parallel to the first wall 242. The first wall 242 is spaced apart from the second wall 246 a distance 250.

A plurality of dosing ribs 252 project from the planar portion 234 of the inner surface 232 to or near the peripheral edge portion 216 and are spaced between the second end 204 and the second wall 246 of the retainer 240. Each dosing rib 252 has a notch 254, an innermost side 256, and an outermost side 258. The spacing between the dosing ribs 252 relates to the predetermined dosage provided in a syringe 50 (FIG. 2) to be contained within the closure container 10. The preferable dosing amounts for which the ribs 252 will be spaced are 0.25 mL, 0.5 mL, 0.75 mL, and 1.0 mL, however, other dosing amounts are contemplated.

Additionally or alternatively, the dosing ribs 152 of the first casing member 100 may be staggered from the dosing ribs 252 of the second casing member 200 to provide more dosing options while still providing secure support of the syringe 50 and the plunger 52.

Additionally or alternatively, the first casing member 100 or the second casing member 200 may not contain the respective dosing ribs, retainer, or the bridge; instead being configured simply to cover the other casing member 200,100.

Looking back to FIG. 1 and also to FIGS. 4-9, the closure container 10 is depicted in from various views with the syringe 50 positioned within the container 10 and the fastener 118 engaged with the second casing member 200. As shown, when the container 10 is in a closed position, the fastener 118 preferably resides substantially within the recess 262, with the barb 128 received within the slot 268.

The material from which the closure container 10 is formed is preferably initially transparent. The window 110 is preferably formed by covering the area in which the window 110 will be located, treating at least the outer surfaces 106,206 of the first casing member 100 and the second casing member 200, respectively, to decrease the transparency of those surfaces, and removing the covering to reveal the window 110. The treatment may be performed by any process now known or later discovered, including but not limited to, chemical etching, mechanical etching (e.g., sand blasting), or during the molding process using textured dies.

Continuing to look at FIG. 1, a syringe 50 can be viewed through the window 110 in a pre-set dosage configuration, ready for use. The window 110 is preferably located at least radially outward from the barrel 64 of the syringe 50 to provide a care provider with a view of the syringe 50 and preferably the dosage amount provided in the barrel 64 without having to open the closure container 10.

Directing attention to FIGS. 16-19, the installation of the syringe 50 into the container 10 is shown. FIG. 16 illustrates the syringe 50 with a predetermined dosage provided in the barrel 64 prior to placement within the second casing member 200; however, the syringe 50 may be placed within the first casing member 100 as well, as shown in FIG. 17.

Looking to FIG. 17, with reference to FIG. 16, the flange 60 of the syringe 50 is placed within the retainer 140 of the first casing member 100 with a portion of the barrel 64 received by the notch 144 of the first wall 142 and another portion of the barrel 64 received by the notch 138 of the bridge 136. Preferably, the distance 150 between the first and second walls 142,146 of the retainer 140 (FIG. 10) is preferably slightly greater than the thickness 62 of the syringe flange 60.

The top 54 of the plunger 52 has a topside surface 56 and an underside surface 58. When installed within the container 10, the underside surface 58 of the syringe top 54 preferably resides against or near the outermost side 158 of the respective dosing rib 152. The placement of the flange 60 within the retainer 140 and the top 54 against the dosing rib 152 reduces the likelihood that the syringe 50 will be accidentally discharged prior to use.

FIG. 18 illustrates the closing of the container 10 with the first and second casing members 100,200 rotating about the hinge 12 (FIG. 17) and adjoining the first casing member peripheral edge portion 116 (FIG. 17) with the second casing member peripheral edge portion 216 (FIG. 17). The barrel 64 of the syringe 50 is thereby also received within the bridge notch 238, the retainer 240, and the respective dosing rib notch 254 of the second casing member 200 (see FIG. 17).

Looking to FIGS. 19 and 20, the engagement of the fastener 118 is shown. The fastener 118 is wrapped around the outside surface 206 of the second casing member 200 within the recess 262. The barb 128 is engageably received within the slot 268 to retain the fastener 118 in the engaged position.

When the time comes for the syringe 50 to be removed from the container 10, the health care personnel will pull the tamper-evident pull-tab 130 away from the container 10 which will tear through the fastener 118 and sever the fastener's connection between the first and second casing members 100,200, thus allowing the container 10 to be opened and the syringe 50 to be removed.

Removal of the tamper-evident pull-tab 130 permanently detaches at least a portion of the fastener 118 from the first casing member 100 when pulled to gain access to the syringe 50. Therefore, tampering with the fastener 118 or the tamper-evident pull-tab in an attempt to gain access to the syringe 50 will be visibly noticeable by a tear in the fastener 118.

FIGS. 21 and 22 demonstrate how multiple containers 10A,10B,10C may be stacked one on top of the other.

As shown in greater detail in FIG. 22, a mateable stacking interaction between a catch 112A and a hole 260B is shown. The interaction allows the containers 10A,10B to be removably interlocked. The catch 112A, along with the other three catches (not shown), of the first container 10A are inserted within the holes 260B of the second container 10B and the containers 10A,10B, are slid in opposite directions relative to one another to place the arm 114A of the first container 10A adjacent to the inner surface 232B of the second container second casing member 200B. These actions are depicted by the dashed lines in FIG. 21.

FIG. 23 illustrates a second embodiment 20 of the closure container according to the present invention. The closure container 20 has tabs 470 projecting from the planar portion 408 of the second casing member outer surface 406 and apertures 390 (FIG. 24) provided through the planar portion 308 of the first casing member outer surface 306. The apertures 390 are alignable and mateable with the tabs 470 of a corresponding closure container 20.

Each tab 470 has a width 472 (FIG. 24), an inward face 476, and an outward face 480. The tabs 470 preferably extend substantially perpendicular away from the outside surface planar portion 408 and comprise a protuberance 478, or similarly shaped protrusion, on the inward face 476 at or near the distal end portion 482 (FIG. 25) of each tab 470. Alternatively, it is contemplated that the protuberance 478 may protrude from the outward face 480.

The apertures 390 have a width 392 and an abutting surface 396. The width 392 of the apertures 390 is preferably slightly greater than the width 472 of the tabs 470.

FIGS. 24 and 25 demonstrate how multiple containers 20A,20B,20C may be stacked by inserting the tabs 470B of a second container 20B within the apertures 390A of a first container 20B. This action is depicted by the dashed lines in FIG. 24. In this fashion, stacking of these embodiments 20 require only a singular directional movement, rather than the compound movement that may be utilized to stack cases according to the first embodiment 10.

FIG. 25 more closely illustrates the interaction between a tab 470B of the second container 20B is received within an aperture 390 of the first container 20A to provide a releasable connection between the two containers 20A,20B. Preferably, the inner face 476B of the tab 470B is substantially flush with the abutting surface 396A of the aperture 390A, whereby the protuberance 478B of the tab 470B is in contact with the planar portion 334A of the first casing member inner surface 332A and the first container's second casing member outer surface planar portion 308A is flush with the second container's first casing member outer surface planar portion 408B.

The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
