  The present invention relates to a package, and more particularly to a package for housing a medical device used for diagnosis or treatment.

  2. Description of the Related Art Conventionally, in the field of food and medical care, a package that is opened by peeling a film so that the contents can be taken out has been used. Such a package is required to be easily opened, and various packages have been proposed from this viewpoint (for example, Patent Documents 1 and 2).

JP 2005-329995 A JP 2006-131284 A

  In particular, as a package used in the medical field, for example, a package that contains a medical device can be cited. In this case, the medical device is sterilized and then stored in a clean storage space formed inside the package, so that the medical device is maintained in a sterile state until use.

  By the way, in operations such as diagnosis and treatment using medical devices, an operator who directly contacts a patient should handle only sterilized medical devices based on the reason that nosocomial infection must be prevented. ing. Therefore, when using a medical device, a nurse or the like who does not directly contact the patient does not place the package on a non-sterilized desk, for example, lifts the hollow medical device and opens the stored medical device to the operator. Provide towards. The surgeon himself takes out the medical device from the opened package. At this time, if it is not easy to open the package, or if a large force is required for opening the package, the medical device during the operation is not delivered smoothly, and a great burden is placed on the patient especially during an emergency operation. It will be tough.

  Moreover, when the package is opened, the possibility that the package is deformed with the formation of the opening and the subsequent smooth and rapid use of the medical device accommodated cannot be denied.

  The present invention solves this type of problem, can be easily opened, avoids deformation of the container made up of medical devices, etc. when opened, and uses the container smoothly and quickly. An object is to provide a packaging that can be made possible.

  The present invention is a packaging body in which a first film and a second film are joined via a seal portion provided at a peripheral portion thereof, and the seal portion includes a peel start seal portion and the peel start seal portion. First and second seal portions adjacent to each other, and the peeling start seal portion has a protruding portion protruding outward from the first and second films, and the peeling start seal portion. The bonding force between the first and second films is smaller than the bonding force to the first and second seal portions.

  With this configuration, at the start of peeling, the peeling can be performed with a weak peeling force, and then the peeling moves toward the seal portion having a strong bonding force as the momentum of the peeling force increases. Accordingly, the first film and the second film are smoothly peeled off, and the contents are not deformed.

  And in this invention, it is preferable that the said 1st seal | sticker part of a package body has smaller joining force than the said 2nd seal | sticker part. Thereby, a 1st seal | sticker part peels preferentially and it can prevent the deformation | transformation of the medical device which is a containment, especially a twist.

  Moreover, the packaging body of this invention is provided with the 1st and 2nd holding part on the outer side of the said peeling start seal part in the said 1st and 2nd film, separating and opening each other while holding. . With this configuration, it is possible to open the package while maintaining the state where the package is lifted hollow.

  Furthermore, it is good also as a structure which the finger insertion part which connected with the said 1st and 2nd holding | grip part and protruded inward was provided in the said peeling start seal part vicinity of the said 1st and 2nd film. . Thereby, it becomes easy to apply force in the direction in which the first gripping portion and the second gripping portion are separated from each other and peeling is started, and the opening operation can be smoothly advanced.

  In addition, it is preferable that the peeling start seal portion is formed so that the protruding portion and the finger insertion portion are adjacent to each other. With such a configuration, the peeling force applied from the finger insertion portion can be easily applied to the protruding portion. The workability of opening is improved.

  Furthermore, the protruding portion may be connected to the first seal portion and the second seal portion, and in addition, when peeling starts from the protruding portion, the peeling portion is more than the second seal portion. Alternatively, the first seal portion may be reached first. In this case, it is preferable that the peeling start seal portion protrudes only outward from the second seal portion.

  In the present invention, the peeling start seal portion of the packaging material has a protruding portion that protrudes outward from the first and second films, and the first and second films are joined to each other at the peeling start seal portion. Since the force is smaller than the joining force of the first and second seal portions, the packaging material can be easily opened, and deformation of the container made of the medical device or the like by the packaging material can be avoided at the time of opening. It is possible to provide a package that can use the contents smoothly and quickly.

It is a schematic plan view of the package which concerns on the 1st Embodiment of this invention. It is a principal part enlarged partial top view in the state where a part of the package was opened. 3A is a perspective explanatory view showing a state where the package shown in FIG. 1 is opened, and FIG. 3B is a plan explanatory view for visually recognizing the opened state of the package shown in FIG. 3A from above. It is a plane explanatory view in the state where the opened state of the package of Drawing 3B was further expanded. It is a principal part expanded partial top view of the package which concerns on the 2nd Embodiment of this invention. It is a principal part expanded partial top view of the package which concerns on the 3rd Embodiment of this invention. It is a partially expanded plan view of a conventional package.

  FIG. 1 is a plan view of a package 10 according to the first embodiment of the present invention, and FIG. 2 is an enlarged plan view of a main part in a state where a part of the package is opened. As a medical device accommodated in the package 10, for example, a medical device used for a catheter treatment performed by introducing various devices such as a catheter into a puncture hole connected to an artery such as a patient's arm or leg. Etc.

  Specifically, for example, an angiographic catheter, an angiographic catheter guide wire, a microcatheter, a PTCA (percutaneous vasodilatation) guiding catheter (right heart shape, left shape, etc.), PTCA guide wire In addition, instruments used for diagnosis and treatment such as PTCA balloon catheters and stent delivery catheters, and other instruments that contain chemicals such as angiographic agents can be listed.

  The package 10 has a first film 12 and a second film 14 joined together via a seal portion 16 provided at the peripheral edge thereof, and a medical device is placed between the first film 12 and the second film 14. A storage space 18 for storage is formed. The seal portion 16 is formed at the peripheral portion between the first film 12 and the second film 14 to be laminated, and is sterilized with a storage space 18 in which medical equipment or the like as a stored item is stored and sterilized. Not isolated from the outside.

  In FIG. 1, both the first film 12 and the second film 14 have a rectangular shape. However, the present invention is not limited to such a form. For example, in addition to a triangular shape, a polygonal shape, a circular shape, Various shapes can be employed. In addition, it is only necessary to form an accommodation space 18 capable of accommodating the contents between the first film 12 and the second film 14, and therefore, the first film 12 and the second film 14 are not necessarily the same shape. There is no need.

  One of the first film 12 and the second film 14 can be made of, for example, a material having heat sealability (heat fusion property). By using this type of material, it is not necessary to provide a layer of adhesive in order to form the seal portion 16. As such a material, for example, a resin material such as a polyolefin resin such as polyethylene or polypropylene, a blend resin of these polyolefin resins, or a polyester resin such as polyethylene terephthalate can be suitably used.

  As described above, the seal portion 16 can be formed by heating and pressurizing a film-like material (thermal fusion). Alternatively, the seal portion 16 may be formed by bonding with an adhesive or a solvent, for example. .

  The remaining one may be a material having heat sealability or a material other than that. For example, in addition to polyethylene as described above, single-layer films such as polyvinylidene chloride, vinyl chloride-vinylidene chloride copolymer, metal foils such as aluminum, silica, etc. deposited on these films, aluminum films, aluminum laminate films, etc. Alternatively, a film containing a metal foil can be used. Furthermore, it is also possible to use a laminate in which two or more of these films are laminated. Moreover, you may use a plastic nonwoven fabric and paper.

  Since the package 10 is sterilized, it is desirable to be able to withstand various sterilization processes such as high-pressure steam sterilization, EOG sterilization, and gamma ray sterilization, and maintain the sterilized state during normal handling such as transportation and storage. It should be possible. Furthermore, it is preferable that one of the first and second films 12 and 14 is made of a transparent material so that the contents can be confirmed from the outside.

  The seal part 16 does not need to be peeled off at the time of normal opening when the peel start seal part 20 and the first seal part 22 and the second seal part 24 adjacent to both sides of the peel start seal part 20 are provided. And a third seal portion 26. The seal portion 16 is formed so as to surround the accommodation space 18 by providing all of these continuously. In FIG. 1, the seal portion 16 has a substantially similar shape of these films along the peripheral edge portions of the first and second films 12 and 14, but is not limited thereto. For example, a deformed seal shape may be used according to the shape of the contents.

  As can be easily understood from FIG. 1, the first seal portion 22 and the second seal portion 24 extend as strips having a predetermined width, and the width W1 of the first seal portion 22 is equal to the width W2 of the second seal portion 24. Narrower. The peeling start seal portion 20 is formed in a W shape so as to be joined to each end portion at a portion where the end portions of the first seal portion 22 and the second seal portion 24 approach and terminate.

  A first gripping portion 28 a and a second gripping portion 28 b are provided outside the peeling start seal portion 20. Since the packaging body 10 includes the first and second gripping portions 28a and 28b, for example, when the peeling starts, the first gripping portion 28a of the first film 12 is left hand and the second gripping portion 28b of the second film 14 is right hand. Can be picked and held, opened to the left and right and separated. In this case, the outer sides of the first seal part 22 and the outer side of the second seal part 24 may also have strip-shaped gripping parts 30a, 30b, 32a, 32b provided along the peripheral edge (see FIG. 1). .

  The end portions of the first seal portion 22 and the second seal portion 24 extend, for example, in a direction intersecting with each other at a predetermined angle toward the peeling start seal portion 20, for example, in a direction substantially orthogonal as shown in FIG. Exist. In this case, the angle at which the first seal portion 22 and the second seal portion 24 intersect is not limited to being substantially orthogonal as described above, and various modifications can be made.

  As described above, the width W1 of the first seal portion 22 is preferably narrower than the width W2 of the second seal portion 24 (see FIG. 2). By doing in this way, it becomes easy to make the joining force of the 1st seal part 22 smaller than that of the 2nd seal part 24. However, the relationship between the width W1 of the first seal portion 22 and the width W2 of the second seal portion 24 is not limited to this. For example, by changing the strength of thermocompression bonding of the first and second seal portions 22 and 24, or forming each seal portion using different adhesives, the first and second seal portions 22 and 24 can be adjusted by adjusting the bonding force between them. The joining force of the seal part 22 may be smaller than that of the second seal part 24.

  The flat W-shaped peeling start seal portion 20 has a protruding portion 34 that protrudes outward, that is, toward a corner portion where the first film 12 and the second film 14 are joined. In the package 10 shown in FIG. 2, one end portion 36 of the W-shaped peeling start seal portion 20 is connected to the first seal portion 22, and the other end portion 38 is connected to the second seal portion 24. The central portion of the W shape is a protruding portion 34. By providing such a protrusion 34, the force required for peeling can be reduced as will be described later. This is because the joining area between the first film 12 and the second film 14 is the smallest.

  Furthermore, in this package 10, the finger insertion part 40 which protruded toward the inner side in which the accommodation space 18 is formed is provided in the vicinity of the peeling start seal part 20. By inserting a finger into the finger insertion portion 40, it is possible to easily apply force to the peeling 34 when opening, and the peeling start becomes easier. In this case, the finger insertion part 40 is preferably provided adjacent to the protruding part 34. By providing the protruding portion 34 and the finger insertion portion 40 adjacent to each other, when the finger is inserted, less force is applied to the peeling start seal portion 20, particularly the protruding portion 34 for peeling, and the opening is opened. The workability can be improved.

  The package 10 according to the present embodiment is configured as described above. Next, the operation when opening the package will be described.

  As shown in FIG. 1, first, for example, a catheter Z as a container is spirally enclosed in the package body 10 in advance, and the inside of the package body 10 includes a peeling start seal portion 20 and a first seal portion 22. The sealed housing space 18 sterilized by the second seal portion 24 and the third seal portion 26 is formed. As described above, in diagnosis and treatment using a medical device, an operator (physician) who comes into direct contact with the patient is to touch only a sterilized medical device. Therefore, the operator is not allowed to touch the outside of the package 10 that is not sterilized. Therefore, when using a medical device, a nurse or the like who does not directly contact the patient opens the package 10, and then directs the medical device, for example, the catheter Z to the operator in an opened state, from which the operator points the catheter Z. Take out.

  As shown in FIG. 3A, the first and second gripping portions 28a and 28b are held by a nurse (not shown) and are not sterilized by other hands, for example, are lifted hollow without being placed on a desk. As shown in FIG. 3B, the first and second gripping portions 28a, 28b are expanded by pulling them left and right, and the corner portions of the first film 12 and the second film 14 are separated and opened. That is, first, the first film 12 and the second film 14 are separated from each other in a state where a finger is inserted into the finger insertion portion 40 and the first and second grip portions 28a and 28b are gripped.

  In this way, with respect to the progress of the peeling operation after the peeling operation of the peeling start seal portion 20 is started, referring to FIG. 2, FIG. 3A, and FIG. 3B, while comparing with FIG. 7 showing the peeling state of the conventional package. This will be described below.

  Here, the peeling is performed by gripping the first and second gripping portions 28a and 28b outside the peeling start seal portion 20 and expanding and separating them by pulling them left and right. Start from the tip of the. In this case, for example, immediately after the start of peeling, the force for pulling the first and second gripping portions 28a and 28b is applied as shown by arrows X1 and X2 in the peeling start seal portion 20 (see FIG. 3B), and the peeling direction ( An arrow Y) points to a corner portion on a diagonal line of the peeling start seal portion 20 of the package 10. And the joining force of the peeling start seal | sticker part 20 in that case is easy to peel, since a sealing distance is short as shown with reference code A1. That is, the bonding force is small. If the force for pulling the first and second gripping portions 28a, 28b is gradually increased, even if the sealing distance is increased as indicated by reference numeral A2, the peeling operation is vigorous, so that the peeling action can be easily continued. .

  Next, in FIG. 2, the seal distance obtained by adding the distances of the joining parts represented by reference signs A3, A4, and A5, and the seal distance obtained by adding the distances of the joining parts represented by reference signs A6, A7, A8, and A9. Even in some cases, the peeling start seal portion 20 can be gradually peeled off without applying much force. This is because when the peeling progresses to the joining portions represented by reference signs A3 to A5, there is a finger insertion portion 40 in which the first film 12 and the second film 14 are not joined, and the reference signs A6 to A6. When the peeling progresses to the joining portion represented by A9, the top part of the non-joining part 42 is exposed to the inside of the protruding part 34, and when the peeling further proceeds, the one end 36 and the other end 38 of the peeling start seal part 20 are exposed. This is because the non-joining portions 46 are exposed to the inside. Since the non-joining portions 42 and 46 are exposed, the joining area between the first film 12 and the second film 14 is reduced, and the force required for peeling can be reduced.

  When the peeling proceeds to the position shown in FIG. 2, the peeling force is applied to the first seal portion 22 and the second seal portion that are continuous with the one end portion 36 and the other end portion 38 that are both end portions of the peel start seal portion 20. The first and second sealing members 22 and 24 are peeled off. If the first film 12 and the second film 14 are separated from each other halfway, the operator can easily take out the contained catheter Z.

  FIG. 4 shows a state where the first film 12 and the second film 14 are peeled off. Here, the catheter Z is omitted for convenience of explanation.

  As can be understood from FIG. 7, when the peeling start seal portion 20 does not exist in the peeling start seal portion 2, the peeling force must be increased at once from immediately after the seal peeling. That is, since the seal length increases rapidly as the peeling progresses from the position D1 immediately after the peeling starts to D2 and D3, the opening operation may be hindered.

  On the other hand, in the packaging body 10 of the present embodiment, the first seal portion 22 is peeled over the whole, and the opening 48 that reaches substantially half of the packaging body 10 is formed by the peripheral portion along the first seal portion 22 side. (See FIG. 4). This is because the bonding force of the first seal portion 22 is smaller than that of the second seal portion 24, and thus the first seal portion 22 side is preferentially peeled off. At this time, the housing space 18 of the package 10 is substantially maintained in the shape before opening. Thus, by preferentially peeling the first seal portion 22 side, the shape of the package 10, that is, the shape of the storage space 18 in which the stored items are stored can be maintained as much as possible. Therefore, it is possible to prevent the container from being deformed at the time of opening, for example, kinking of the catheter Z, and it is possible to prevent the container from being damaged or dropped.

  In addition, after peeling the peeling start seal part 20, it is not necessary to continue to hold the first and second gripping parts 28a and 28b. For example, when the first seal part 22 peels to a predetermined position, the first seal You may hold | grip and open the strip | belt-shaped holding parts 30a and 30b provided in the outer side along the part 22. FIG.

  Moreover, in the package 10 shown in FIG. 4, the first and second seal portions 22 and 24 and the portion that was the peeling start seal portion 20 are shown as remaining on the second film 14 as traces. This trace may remain on both the first and second films 12 and 14 after peeling.

  Next, a packaging body 10 according to a second embodiment of the present invention will be described with reference to FIG. In 2nd Embodiment, the same referential mark is attached | subjected to the structure which is common in 1st Embodiment, the overlapping description is abbreviate | omitted, and it is the same below.

  In the package 10, the protruding portion 54 of the peeling start seal portion 52 is directly connected to the first seal portion 22 and is provided toward the first and second grip portions 28 a and 28 b on the outer side. In this case, the protrusion 54 has a single band shape. The angle θ formed between the major axes of the projecting portion 54 and the first seal portion 22 is preferably greater than 90 °, for example, 135 to 180 °. It is because peeling is performed smoothly.

  The reason why the protruding portion 54 is connected to the first seal portion 22 is to preferentially start the peeling of the first seal portion 22 having a small bonding force. The force that peels off the protruding portion 54 reaches the position B3 through the parts B1 to B2 shown in FIG. At this time, the force for peeling the protruding portion 54 is continuously transmitted to the first seal portion 22 side that is continuous with the protruding portion 54, and this is coupled with the fact that the bonding force of the first seal portion 22 is small. The first seal portion 22 is preferentially peeled off from the second seal portion 24.

  In other words, according to such an embodiment, since the projecting portion 54 is provided so as to peel the first seal portion 22 preferentially when the package 10 is opened, the first seal portion 22 is provided. Can be quickly removed, and the opening operation of the package 10 can be performed smoothly.

  Moreover, in the package 10 of this embodiment, since peeling of the 1st seal | sticker part 22 advances rapidly, the same opening shape as the package 10 which concerns on 1st Embodiment shown in FIG. 4 is obtained. Can do. Therefore, similarly to the first embodiment, the shape of the accommodation space 18 in which the accommodation is accommodated can be maintained as much as possible, and the occurrence of breakage or dropping due to the kinking of the accommodation at the time of opening is prevented. can do.

  Next, a packaging body 10 according to a third embodiment of the present invention will be described with reference to FIG.

  The package 10 has a protrusion 60 that protrudes only outward from the second seal portion 24 and does not protrude outward from the first seal portion 22 in the peeling start seal portion 58. According to such a configuration, when peeling is started from the protruding portion 60, the peeling can be exerted on the first seal portion 22 before the second seal portion 24.

  That is, peeling is started at the site C1, and the peeling force reaches the first seal portion 22 at the position C2. Therefore, after that, the first seal portion 22 having a small bonding force is peeled preferentially, and the package 10 is opened. Accordingly, in this case as well, as shown in FIG. 4, the shape of the accommodation space 18 can be maintained, and the breakage and the drop caused by the kinking of the contents at the time of opening can be prevented.

  The present invention is not limited to the above-described embodiment, and it is naturally possible to adopt various configurations without departing from the gist of the present invention.
