    PACKAGING FOR SYRINGE AND METHOD OF REMOVING A SYRINGE FROM A PACKAGING. A package comprising a syringe and a blister package is described. The blister pack incorporates elements that allow opening with just one hand. This result is obtained by a sealed width of the substantially reduced-width flange region adjacent to the flange region with reference to the packaged syringe relative to the sealed width of the distal region. This allows the syringe to be squeezed out of the package with one hand so that, after removing the syringe from the blister package, the flange region and proximal region come out of the package before the distal region. Methods for removing a syringe from a package using one hand are also described.

    TECHNICAL FIELD
    [0001] The present invention relates to packages and, more specifically, to a package for storing a syringe, from which the syringe can be removed from the package using only one hand. FUNDAMENTALS
    [0002] Clean or sterile articles useful particularly for medical applications are packaged to preserve their sterility. The packaging for these items is intended to provide a barrier to prevent microorganisms from entering the packaging to contaminate its contents. In most cases, the package is opened immediately before using the article, as with a blister pack for storing a syringe, in order to minimize the period of time the article is exposed to non-sterile conditions.
    [0003] Traditionally, in order to avoid contamination, the syringe is located loosely inside the conventional blister pack. The blister pack provides a compartment that is sealed against ingress of contaminants and prevents contamination of the syringe. Conventional blister packaging, however, requires two hands and the articulate-roll-unstick the package technique.
    [0004] In the fast paced environment of a hospital or other medical setting, where there is little time to handle syringe packaging, this two-handed opening process is complicated and time-consuming. Medical technicians are often doing multiple tasks at the same time, and, due to conventional blister packaging design, technicians must free both hands to open the blister pack in order to make an aseptic presentation of the syringe.
    [0005] In addition, the traditional two-handed joint-roll-peel technique required to open conventional blister packaging often compromises sterility. The package, if opened in the wrong 2/18 direction or in a hurry, may tear or break. This fiber tear is the delamination of either the upper or lower mesh of the blister packaging material. Such tears introduce foreign bodies into the syringe product, exposing the syringe to non-sterile conditions.
    [0006] In addition, the conventional blister packaging consumes a significant amount of material as the packaging requires a peel-off flap for the user to open the package. This extra packaging material leads to an increase in the cost of each syringe product. Additionally, the additional packaging then needs to be discarded when opening the packaging, leading to an increase in the amount of waste produced in a hospital or other medical setting.
    [0007] Figures 1-4 show a conventional syringe package and the opening of a conventional syringe package. Figures 1 and 2 illustrate a conventional syringe package. Referring to Figure 1, pack 2 includes a syringe 4 and a blister pack 6. The blister pack 6 is comprised of a flexible mesh sealed to a protective coating, thus defining a compartment and providing a sealed region 8 on the periphery support for holding the syringe 4. The blister pack also includes at least one peel-off tab 9 for the technician to use when opening the blister pack to release the syringe. Referring to Figure 2, the width of the sealed region 8 is equivalent to the entire support periphery. In other words, whatever the sealing mechanism, the sealed region is the same dimension between the syringe and the edge of the package around the entire package 6.
    [0008] Figures 3 and 4 illustrate the opening of a conventional syringe package. Referring to Figures 3 and 4, with a swivel-roll motion, the outer packaging material is peeled off using both hands, and the product is released. In other words, the two-handed articulate-roll-peel technique used to open package 2 requires placing the fingers of both hands on either side of flaps 3/18 to peel 9 from package 2 and using the thumbs to roll and peeling off the sealing material, peeling off the flexible mesh from the protective support to release the syringe 4 separate from the blister pack 6. This opening with two hands is very complicated and time-consuming for the technician, as it requires the technician to have both hands free to open the package. In addition, the traditional two-handed joint-roll-peel technique to open a conventional blister pack often compromises sterilization. The package, if opened in the wrong direction or in a hurry, can tear or break. This fiber tear is the delamination of either the upper or lower web of the blister packaging material. These tears introduce foreign bodies into the syringe product, exposing the syringe to non-sterile conditions.
    [0009] It would be advantageous to provide a package for a syringe that does not require the traditional two-handed swivel-roll-peel technique and that does not include a peel-off flap for opening. RESUME
    [0010] Aspects of the invention are directed to a package storing a syringe. Packages in accordance with a first aspect of the present invention include a syringe and a blister package surrounding the syringe. The syringe will normally be sterile in the package. Blister packaging is comprised of a flexible mesh sealed in a protective backing defining a compartment that surrounds the syringe that allows the syringe to be squeezed out of the packaging. Syringe removal features allow the syringe to be removed from the package with one hand without compromising sterility.
    [0011] In one or more embodiments, the syringe is composed of a proximal region, having a width and including a flange and a flange region, a distal region, having a width and a body extending from the proximal region to the region. distally, the flange region having a width greater than the width of the distal region and the proximal region. The syringe is wrapped in a blister pack. The blister package comprises a flexible mesh sealed in a protective backing defining a compartment around the syringe and providing a sealed region on a periphery of the protective backing, the sealed region defining a sealed width in the proximal region, a sealed width in the distal region and a sealed width in the flange region, the substantially reduced sealed flange region adjacent the flange region relative to the sealed width of the distal region to allow the syringe to be squeezed out of the package with one hand so that after removal of the syringe of the blister pack, the flange region and the proximal region come out of the pack before the distal region.
    [0012] In one or more embodiments, the sealed width of the flange region includes a vanishing point. The vanishing point allows the flange region to come out of the package after being squeezed. The vanishing point can define an angled sealed region having a sealed width that is reduced compared to the sealed width of the distal region. The angled sealed region can include a point of a triangle, or the angled sealed region can include at least two points forming a box.
    [0013] In one or more embodiments, the sealed width of the flange region may define a curved radius that allows the syringe to be squeezed out of the package with one hand.
    [0014] In one or more embodiments, the sealed width of the flange region adjacent the flange region is reduced relative to the sealed width of the distal region. The sealed width of the flange region adjacent the flange region can be reduced by at least 1/16, at least 1/8, at least % or at least 14 relative to the sealed width of the distal region.
    [0015] The second aspect of the present invention is directed to a package comprising a syringe comprising a proximal region with a width that includes a flange and a flange region, a distal region with a width, and an extending body. if from the proximal region to the distal region, the flange region having a width that is greater than the width in the distal region and the proximal region, the syringe is surrounded by a blister pack. The blister package includes a flexible mesh sealed in a protective backing defining a compartment around the syringe and providing a sealed region on a periphery of the protective backing, the sealed region having a shape that conforms to the flange shape such that the sealed width adjacent to the flange is reduced compared to the width in the distal region.
    [0016] In one or more embodiments, the sealed width adjacent to the flange is reduced compared to the width of the distal region. The sealed width adjacent to the flange can be reduced by at least 1/16, at least 1/8, at least % or at least 1/∑ compared to the distal region.
    [0017] Another aspect of the present invention is directed to a method of removing a syringe from a package. The method comprises squeezing the package of the invention with one hand, so that after removing the syringe from the blister package, the flange region and the proximal region of the syringe come out of the package before the distal region.

    [0029] Before describing various exemplary embodiments of the invention, it is understood that the invention is not limited to the construction details or process steps set forth in the description below. The invention is capable of other modalities and being practiced or being carried out in various ways.
    [0030] With respect to the terms used in the disclosure, definitions are provided below.
    [0031] As used in this document, the use of "an", "an" and "the", "the" includes the singular and the plural.
    [0032] Reference to "syringe" includes syringes that are intended for use with needles, mouthpieces, tubes, or for use in discharge systems. As used herein, the term "syringe" refers to a simple pump-like device that consists of a plunger rod that fits tightly into a pipe or tube. The plunger rod can be pulled or pushed into the body, allowing the syringe to collect and expel a liquid or gas through an opening in the open end of the body. The open end of the syringe can be equipped with a needle, mouthpiece or tube to help direct fluid flow into and out of the body. The syringe can be sterile or non-sterile depending on the technician's needs.
    [0033] As used herein, the terms "packaging" or "packaging" includes any material used to wrap or protect a good or product, such as a syringe. Packaging can be rigid or flexible. Packaging includes, but is not limited to, medical packaging, pharmaceutical packaging and child resistant packaging. Medical and pharmaceutical packaging may include blister packaging.
    [0034] In this document, the terms "blister package" or "blister package" includes various types of preformed packages used for consumer goods, food, pharmaceuticals, medical devices, etc. The main component of a blister is a cavity or pocket made of molded mesh, usually a thermoformed plastic. A molded net can be rigid or flexible. The cavity or pocket is large enough to contain the good that is housed in the blister pack. Depending on the application, a blister pack may have a protective backing of thermoformed material and a sealed lid of aluminum foil, paper, Tyvek®, plastics, or other medical grade materials. Blister packs can also be hinged plastic packs, which may include a rigid backing such as cardboard. Blister packs can provide barrier protection from microorganisms and other contaminants and can provide some degree of lid strength. Among the many options that blister packs provide, the blister pack must protect the contained product while still inside, while still possessing the 8/18 feature capable of making automated processing possible.
    [0035] Blister packs are commonly used as unit dose packages for pharmaceutical tablets, capsules or lozenges. The pharmaceutical product and its blister pack act together to serve as an integral unit. The blister pack protects the pharmaceutical product from external influences that would otherwise render it useless while allowing the manufacturer of the pharmaceutical product to pack it using sealed packaging equipment. The seal packaging process involves creating blister packs and flat sheet rolls or film, filling with pharmaceutical product such as a drug tablet and closing (sealing). This type of blister packaging is sometimes referred to as push-through packaging, because the consumer can push the good (eg drug tablet) through the backing. With pharmaceutical blister packs, manufacturers must be concerned about the moisture vapor transmission rate of the blister pack because many pharmaceutical products degrade and lose their effectiveness through hydrolysis. In addition, the packaging must provide an oxygen barrier to prevent degradation of the pharmaceutical product through oxidation. In one or more embodiments, the blister pack is a push-through type pack.
    [0036] Blister packs that contain medical devices, such as a syringe, differ from pharmaceutical blister packs because medical blister packs are not push-through. Instead, a thermoformed base mesh is made of a thicker plastic and cannot be broken, thus forming a solid support. The capping film provides a peel-to-open feature that can be opened by peeling off using two hands, such as the hinge-roll-peel technique. The cover film of a medical blister pack is usually porous to allow sterilization. Medical blister packs are often made of Tyvek® or a similar medical grade material that is breathable and gas permeable. The 9/18 capping film can also be made from medical grade paper or a completely non-permeable or non-breathable film. In cases where a non-breathable film is used, sterilization is via radiation (eg electron beams (E-beam)). In one or more embodiments, the blister pack is a medical blister pack.
    [0037] Blister packs can be created through thermoforming or cooling molding. In the case of thermoforming, a plastic film or foil is unrolled from a spool and guided through a pre-heating station on the blister line. The temperature of the preheat plates is such that the plastic will soften and become flexible. The hot plastic then arrives at a forming station where high pressure forms the blister cavity in a negative mold. The mold is cooled so that the plastic becomes firm again and retains its shape when removed from the mold.
    [0038] In the case of cooling molding, a laminated film with an aluminum base is simply pressed into a mold by means of a stamp. Aluminum stretches and maintains the formed shape. The use of aluminum provides a complete barrier to water and oxygen. However, cooled molded blister packs take longer to produce compared to thermoforming. Cooling molded blister packs are also not transparent, which can lead consumers to not comply with pharmaceutical therapies.
    [0039] The thermoforming capable of supporting the medical blister pack is generally comprised of a thermoformable flexible plastic film. The film is often composed of several layers. The main component is regularly a layer of approximately 15-30% nylon, while the remaining layers may include substances including, but not limited to, polyethylene. The sealant layer may include, among others, ethyl vinyl acetate (EVA).
    [0040] The lid film of a medical blister pack can be made of plastic, aluminum or medical grade papers which are permeable to gas for sterilization but are impermeable to micro-organisms. Most commonly, Tyvek® is used as a capping material for medical blister packs.
    [0041] Blister packaging may also include the cartouche, where a card or other material of the protective coating and product are covered with a thin sheet of clear plastic. The backing usually has a heat seal on the coating. The plastic film is softened by heat and draped over the product over the backing. Vacuum is sometimes used to aid in a snug fit. Immediately after forming a blister, the blister is transported to a vacuum sealing station where a vacuum is pulled and the blister is sealed, providing the comfortable fit. The plastic film binds to the heat seal coating on the card or other backing. In one or more embodiments, the blister pack is a vacuum sealed thermoformed blister pack.
    [0042] Blister packs are sealed in a variety of ways, including, but not limited to, packaging and cold sealing. Cap materials can have a heat seal of the coating applied to them; the cap is then sealed to the backing using heat, which activates the liner. Blister packs can also be sealed using a cold sealing process, which uses a combination of a pressure foldable blister sensitive card and a clear blister; the blister is trapped between two pieces of board that are bonded together under pressure without using any heat. Furthermore, blister packs can be sealed by orienting multiple layers of film correctly so as to make a seal.
    [0043] As used herein, the term "microorganism" refers to a microbe or organism that is unicellular or lives in a colony of cellular organisms. Microorganisms are very diverse; they include, but are not limited to, bacteria, fungi, archaea, and 11/18 protozoa.
    [0044] Tyvek® is a synthetic material, consisting of flashspun high density polyethylene fibers (ie, a spunbound olefin fiber). The material is light and strong and is tear resistant, but can be cut with a knife or scissors. Water vapor and other gases can pass through Tyvek® as the material is highly breathable, but at the same time the material is impermeable to micro-organisms and liquid water.
    [0045] As used herein, the term "sterilization" refers to a means to eliminate or kill microorganisms present on a surface, contained in a fluid or a compound, such as biological culture media to achieve asepsis or a sterile and microbial environment. Sterilization can be achieved through the application of heat, chemicals, radiation/irradiation, high pressure, filtration or combinations thereof. Chemical sterilization includes sterilization with gas such as oxide and ozone liquids, hydrogen peroxide, ethylene gas such as chlorine, iodine, glutaraldehyde and formaldehyde, Ortho-phthalaldehyde (OPA), hydrogen peroxide, peracetic acid, sodium hydroxide, silver, and cobalt. Radiation sterilization involves the use of radiation such as electron beams (E-beam), x-rays, gamma rays or subatomic particles.
    [0046] In this document, the term "joint-roll-unstick technique" refers to the process by which a technician, such as a doctor or nurse, opens a package to release the product contained therein. With a pivoting and rolling motion, the outer packaging of the material is peeled off using both hands, and the inner product is released.
    [0047] Packages are provided that include a syringe surrounded by a blister package, incorporating elements to open the blister package with one hand while maintaining the sterility of the syringe. Packaging in accordance with one or more embodiments of the present invention uses less material than conventional two-handed packaging. Conventional packages require a 12/18 peel flap to allow the user/technician to open the package; the peel-off flap is used by the technician in the joint-roll-unstick technique. Peel flaps provide a significant amount of additional packaging material, which results in increased waste production for hospitals and other medical settings. For example, in each 10 ml Luer-Lok syringe there is an addition of 1 inch2 of top and bottom mesh material. Thus, by eliminating the peel-off flap, the packaging of the present invention can lead to a reduction of about 4 billion inches2 of waste worldwide. Waste reduction can translate into cost savings. Furthermore, the one-handed packages of the present invention are less heavy than conventional packages and do not compromise sterility.
    [0048] Figures 5 and 6 illustrate a syringe package according to one or more embodiments of the present invention. Referring to Figure 5, package 10 is comprised of a syringe comprising a proximal region 14 having a width 12, and including a flange 16 and a flange region 18, a distal region 20 having a width and a body 22 extending From proximal region 14 to distal region 20, flange region 18 having a width that is greater than the width at distal region 20 and proximal region 14. Syringe 12 is surrounded by a blister pack 30. In one or more modalities, syringe 12 is sterile.
    [0049] Still referring to Figures 5 and 6, the blister package 30 comprises a flexible mesh 32 sealed to a holder 34 defining a compartment 36 to surround the syringe 12 and provide a sealed region 38 on a periphery of the holder 34. sealed region 38 defines a proximal region seal 40 having a width W1, a distal region seal 42 having a width W2 and a flange region seal 44 having a width W3. The sealed width of the flange region W3 is substantially reduced adjacent the flange region 18 relative to the sealed width of the distal region W2 to allow the syringe to be squeezed out of the package with one hand. Upon removal of syringe 12 from blister package 30, flange region 18 and proximal region 14 of the syringe exit package 10 before distal region 20.
    [0050] Flexible mesh 32 can comprise plastic films, such as flexible heat shrink plastics, including, but not limited to, nylon based films with polyethylene and ethyl vinyl acetate (EVA). Backing 34 can hold Tyvek® or other medical grade materials such as paper or flexible films. Flexible mesh support materials are permeable to radiation and gas, but are not permeable to microorganisms. Thus, packages according to one or more modalities can be sterilized.
    [0051] Referring to Figure 6, in one or more embodiments, the package 10 may include a vanishing point 50 along the sealing of the flange region 44. The vanishing point 50 allows the flange region 18 to exit the packing 10 squeezing. The holding force at the leak point 50 will vary depending on the type of syringe 12 contained in the blister pack 30. For example, if a % mL syringe is contained within the blister pack 30 minus the holding force will be required by the leak point 50 than if a 10 ml syringe is contained within the blister pack 30. In other words, the holding force, in one or more modalities, will be greater for larger syringe products. The leak point 50 is intended to take advantage of the sharpness of the syringe product design and therefore is generally in line with the flange region 18. The design of the leak point 50 is optimized according to different medical products (or i.e., syringe), particularly with respect to sizes and shapes of syringe 12. Leakage point 50 has a holding force less than the holding force of the rest of the sealed blister package 30. The total energy required to break the sealing of the blister pack is the same, but the energy required to remove the product from the syringe 12 14/18 through the leak point 50 is significantly less than if the syringe were to exit the blister pack 30 at any other point along the seal .
    [0052] In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1/16 adjacent the flange region 18 relative to the sealed width of the distal region W2. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1/8 adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the sealed width of the flange region is reduced by at least % adjacent the flange region compared to the sealed width of the distal region. In one or more embodiments, the sealed width of the adjacent flange region W3 is reduced by at least that of the flange region compared to the sealed width of the distal region W2.
    [0053] Referring to Figure 7, in one or more embodiments, sealed region 138 defines a proximal region seal 140 having a width W1, a distal region seal 142 having a width W2 and a flange region 144 having a width W3. The sealed width of the flange region W3 is substantially reduced adjacent the flange region relative to the sealed width of the distal region W2 to allow the syringe to be squeezed out of the package with one hand. In one or more embodiments, the sealing of the flange region 144 of the blister pack 130 defines a curved radius 146 that provides a leakage region 150, having a sealed width W3 that is reduced compared to the sealed width of the distal region W2. The leak region 150 allows the syringe to be squeezed out of the package with one hand. The holding force at the leak region 150 will vary depending on the type of syringe contained within the blister pack 130. Larger or heavier syringes are likely to require a greater/greater holding force than smaller or lighter syringes. In one or more embodiments, the sealed width of the 15/18 flange region W3 is reduced by at least 1/16 adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1/8 adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the width of the flange region W3 is reduced by at least % adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1Z> adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the syringe is sterile.
    [0054] Referring to Figure 8, in one or more embodiments, sealed region 238 defines a proximal region seal 240 having a width W1, a distal region seal 242 having a width W2 and a flange region seal 244 having a width W3. The sealed width of the flange region W3 is substantially reduced adjacent the flange region relative to the sealed width of the distal region W2 to allow the syringe to be squeezed out of the package with one hand. In one or more embodiments, the vanishing point 250 along the sealed width of the flange region 244 defines an angled sealed region 246 having a sealed width W3 that is reduced compared to the sealed width of the distal region W2. The angled sealed region 246 may comprise a point of a triangle. Leakage point 250 allows the syringe to be squeezed out of the package with one hand. The retention force at the vanishing point 250 will vary depending on the type of syringe contained within the blister pack 230 and depending on the materials used to make the blister pack. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1/16 adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1/8 adjacent the flange region compared to the sealed width 16/18 of the distal region W2. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least % adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 50% adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the syringe is sterile.
    [0055] Referring to Figure 9, in one or more embodiments, sealed region 338 defines a proximal region seal 340 having a width W1, a distal region seal 342 having a width W2 and a flange region 344 having a width W3. The sealed width of the flange region W3 is substantially reduced adjacent the flange region relative to the sealed width of the distal region W2 to allow the syringe to be squeezed out of the package with one hand. In one or more embodiments, the vanishing point 350 along with the sealing flange region 344 defines an angled sealed region 346 having a sealed width W3 that is reduced compared to the sealed width of the distal region W2. The angled sealed region 346 may comprise at least two points forming a box. Leak region 350 allows the syringe to be squeezed out of the package with one hand. The holding force at the leak region 350 will vary depending on the type of syringe contained within the blister pack 330. Larger or heavier syringes are likely to require a greater holding force than smaller or lighter syringes. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1/16 adjacent the flange region compared to the sealed width of the distal region W2. In one or more embodiments, the sealed width of the flange region W3 is reduced by at least 1/8 the adjacent flange region compared to the sealed width of the distal region W2. In one or more embodiments, the width of the flange region W3 is reduced by at least % adjacent the flange region compared to the sealed width of the distal region W2. In one or more 17/18 modalities, the sealed width of the flange region W3 is reduced by at least % adjacent the flange region compared to the sealed width of the distal region W2.
    [0056] Referring to Figures 5 and 6, a second aspect of the present invention is directed to package 10 comprising a syringe 12 which is typically sterile, the syringe comprising the proximal region 14 having a width and including the flange 16 and the flange region 18, a distal region 20 having a width and a body 22 extending from the proximal region 14 to the distal region 20, the flange region 18 having a width that is greater than the width of the distal region 20. and in the proximal region 14. Syringe 12 is surrounded by blister pack 30.
    [0057] Blister packaging 30 comprising a flexible mesh 32 sealed to a backing 34 defining a housing 36 for surrounding the syringe 12 and providing a sealed region 38 on a periphery of the backing 34. The sealed region 38 having a shaped shape it conforms to the flange shape 16 so that the width W3 of the sealed region adjacent to the flange is reduced compared to the width W2 of the sealed region in the distal region. In one or more embodiments, syringe 12 is sterile. Syringe 12 can be squeezed out of package 30 with one hand. Upon removal of syringe 12 from blister package 30, flange region 18 and proximal region 14 exit package 10 before distal region 20. In one or more embodiments, the sealed width of flange region W3 is reduced by at least 1 /16 adjacent flange region 18 compared to the sealed width of distal region W2.

    [0058] Another aspect of the present invention is directed to a method of removing a syringe from a package. Referring to Figures 10 and 11, the method comprises squeezing the package 410 into the flange region 418. When the package 410 is squeezed, the flange region 418 and the proximal region 414 of the syringe 412 exit the package 410 before the distal region 420 of syringe 412. In one or more embodiments, syringe 412 is sterile. In one or more embodiments, the package 410 is squeezed through the flange region 418 with one hand 460. Opening the package with one hand is less complicated for the technician and allows the technician to use their other available hand for additional tasks.
    [0059] Although the invention has been described herein with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. And, therefore, it should be understood that numerous modifications can be made to the illustrative embodiments and that other arrangements can be loaded without departing from the spirit and scope of the present invention as disclosed. 1/3
