Description

Technical Field

[0001] The present invention relates to a packaging container for housing an object in a recess formed on a resin sheet and sealing the recess with a sealing film. Background Technology

[0002] A packaging container has been previously proposed that houses a medical device in a recess formed on a resin sheet and seals the recess with a flat sealing film such as a resin film (Patent Document 1). Such packaging containers are also known as blister packs, blister shells, etc., and are used, for example, for packaging pre-filled syringes, drug delivery devices that are attached to the body, etc.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2011-005182 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] Regarding medical devices, there are also devices whose function is impaired if touched by hand when removing them from their packaging. However, current packaging containers allow the sealing film to be opened with uniform force across the entire area around the recess, creating a possibility that the user might peel off the entire sealing film at once. In this case, the entire contained medical device is exposed at once, and the user may come into contact with any part of the device. Therefore, there is a possibility that the user might grasp the wrong part, leading to a decrease in the function of the medical device.

[0008] Furthermore, due to the increasing prevalence of home-based therapy in recent years, patients have more opportunities to operate medical devices themselves. This increases the possibility of misoperation when users unfamiliar with the operation of medical devices remove them from their packaging. For products other than medical devices, there are those whose functionality may decrease if carelessly touched during removal from packaging.

[0009] Therefore, there is a need for packaging containers that can prevent users from touching the wrong parts and taking out the contents.

[0010] Methods for solving problems

[0011] The following is a disclosed viewpoint regarding a packaging container for containing a stored object having a protected portion that should be avoided when removing it and a grippable portion. The packaging container is characterized by comprising: a container body having a recess and an adhesive portion, wherein the recess is shaped to correspond to and accommodates the stored object, and the adhesive portion is planar in the portion surrounding the recess; and a sealing film that is peelably attached to the adhesive portion and seals the recess, the sealing film being bonded to the adhesive portion by means of a sealing portion extending around the recess, the sealing portion having: a difficult-to-peel portion formed in the portion surrounding the protected portion of the stored object contained in the recess and bonded with relatively high strength; and an easy-to-peel portion formed in the portion surrounding the grippable portion of the stored object contained in the recess and bonded with relatively low strength compared to the difficult-to-peel portion.

[0012] Invention Effects

[0013] According to the above viewpoint, the packaging container has a difficult-to-peel portion that makes the sealing film difficult to peel off, which protects the part of the container surrounding the object to be stored. Therefore, it can prevent the user from touching the wrong part and taking out the container. Attached Figure Description

[0027] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. It should be noted that, for ease of explanation, the dimensions in the drawings may be exaggerated and differ from the actual dimensions.

[0028] (First Embodiment)

[0029] Figure 1 The packaging container 10 shown in this embodiment is used to house a patch-type small drug delivery device 12 (medical device) that is attached to a patient's body. The packaging container 10 includes: a container body 16 having a recess 14 formed therein capable of housing the drug delivery device 12 within a transparent, thick resin sheet; and a sealing film 18 adhered to the container body 16 to seal the drug delivery device 12 housed in the recess 14. It should be noted that in this embodiment, the drug delivery device 12, as a type of medical device, is described as the object housed in the packaging container 10, but the present invention is not limited to this. The packaging container 10 can also accommodate various devices, such as various sensors, fragile structures (syringes), etc., that have parts that may experience functional degradation upon contact.

[0030] like Figure 2 As shown, the drug dispensing device 12 has a box-shaped frame 20. Inside the frame 20 are: a cylinder containing the drug solution; a pressing element for dispensing the drug solution; and a drive mechanism for driving the pressing element. The drug dispensing device 12 is used to continuously or intermittently dispense drug solution into a living organism over a relatively long period of time (e.g., from a few minutes to several hours).

[0031] like Figure 3 As shown, the frame 20 has a rectangular front 20a and back 20b, and four sides 20c to 20f. The front 20a and back 20b have a larger area than the sides 20c to 20d. A patch-type connection port 22 for connecting a needle tube or the like is provided on the side 20c. In addition, a power switch 25 is provided on the back 20b of the frame 20. The power switch 25 is a switch that starts the dispensing operation of the drug dispensing device 12, and is positioned facing the patient's body after the power switch 25 is pressed.

[0032] The frame attachment 24 forms a mating surface 24a that engages with the frame 20, and another adhesive surface 24b that can adhere to the skin. To ensure peel strength with the skin, the frame attachment 24 is shaped to be the same as or larger than the back surface 20b of the drug dispensing device 12.

[0033] Furthermore, a protective sheet 28 is affixed to the frame attachment 24 to protect the adhesive surface 24b before use and prevent a decrease in its adhesiveness. The protective sheet 28 is shaped to cover the entire area of ​​the adhesive surface 24b. The protective sheet 28 is removed from the frame attachment 24 before use of the liquid dispensing device 12, and a peeling start portion 30 for separation from the frame attachment 24 is provided at one end 28a (the end on the side 20f side).

[0034] The peel-off start portion 30 is integrally formed with the protective sheet 28, which is formed to bulge outwards compared to the frame attachment 24. The peel-off start portion 30 is separated from the adhesive surface 24b of the frame attachment 24 and does not contact the adhesive surface 24b. The user can easily peel the protective sheet 28 off the frame attachment 24 by grasping the peel-off start portion 30 and pulling the protective sheet 28 from the frame attachment 24 in the tearing direction.

[0035] A power switch 25 for starting the drive of the liquid dispensing device 12 is provided on the back 20b of the frame 20. A circular notch 27 is provided on the part of the frame where the attachment 24 and the protective plate 28 are attached, corresponding to the power switch 25, so that the power switch 25 can be visually identified and operated.

[0036] On the other hand, such as Figure 1 As shown, the container body 16 has: a recess 14; a planar adhesive portion 32 surrounding the recess 14; and a middle portion 34 formed between the recess 14 and the adhesive portion 32. The recess 14 has: a body receiving portion 36 that receives the frame 20 of the liquid dispensing device 12; and a port receiving portion 38 that receives the connection port 22.

[0037] The main housing 36 is formed into a rectangle surrounded by four sides 36a, 36b, 36c, 36d and a bottom surface 36e. The planar dimensions of the main housing 36 are larger than the planar dimensions of the front side 20a and the back side 20b of the frame 20. In addition, the depth of the main housing 36 (the depth from the middle part 34 to the bottom surface 36e) is larger than the thickness of the frame 20 (the distance between the front side 20a and the back side 20b), and the entire frame 20 is housed within the main housing 36.

[0038] The main body receiving section 36 is provided with a plurality of protrusions 40 protruding from the sides 36a, 36b and the bottom surface 36e toward the frame 20. The frame 20 is held within the main body receiving section 36 by the four protrusions 40 protruding from the sides 36a, 36b respectively. In addition, the frame 20 abuts against the protrusions 40, thereby holding it in a state of floating from the sides 36a, 36b and the bottom surface 36e.

[0039] When the frame 20 of the liquid dispensing device 12 is removed from the container body 16, gripping recesses 42 are formed on the sides 36a and 36b of the main body receiving portion 36 to facilitate gripping of the frame 20. The gripping recesses 42 form a gap that allows the user to insert their fingertips. Outside of the gripping recesses 42, the gap between the main body receiving portion 36 and the liquid dispensing device 12 is formed to a width that does not allow the user to insert their fingers.

[0040] A port receiving portion 38 is formed in the recess 14 as part of the side 20c of the housing 20. The port receiving portion 38 is formed to be larger than the connection port 22, and the connection port 22 is received in the port receiving portion 38 in a state separate from the surface of the port receiving portion 38. When the medicine dispensing device 12 is removed, in order to prevent the user from contacting the connection port 22 and damaging it, the gap between the port receiving portion 38 and the connection port 22 is preferably a width such that the user's fingertip will not enter.

[0041] The intermediate portion 34 is formed around the recess 14 and has a plane parallel to the adhesive portion 32. The inner periphery of the intermediate portion 34 is connected to the recess 14. Furthermore, the outer periphery of the intermediate portion 34 is connected to the adhesive portion 32 via a lamination portion 34a. The intermediate portion 34 is formed lower than the adhesive portion 32 by means of the lamination portion 34a. The intermediate portion 34 forms a space between itself and the sealing film 18 for accommodating the frame attachment 24 and the protective sheet 28 of the liquid dispensing device 12.

[0042] The adhesive portion 32 is rectangular in shape along the outer periphery of the container body 16. The width of the adhesive portion 32, i.e., the distance between the layer difference portion 34a and the outer peripheral edge 32a, is approximately constant throughout the circumference. Furthermore, a separating portion 33 is formed at the end of the adhesive portion 32 on the side of the port receiving portion 38. The separating portion 33 is connected to the adhesive portion 32 via the layer difference portion 33a and is formed at a lower position than the adhesive portion 32. The separating portion 33 separates from the sealing film 18 when it is bonded to the adhesive portion 32 (described later), thus becoming a portion that allows the user to easily hold the sealing film 18 when beginning to peel it off.

[0043] The container body 16 integrally forms the recess 14, the adhesive portion 32, and the intermediate portion 34 using a resin sheet. For example, a transparent sheet made of PET resin can be used as the resin sheet. In this case, a thick sheet of approximately 0.8 mm can be used.

[0044] The liquid dispensing device 12 is housed in the recess 14 of the container body 16 with the front 20a of the frame 20 facing the bottom 36e of the recess 14. Furthermore, the frame of the liquid dispensing device 12, along with the attachment 24 and protective sheet 28, is extended and housed in the middle portion 34 of the container body 16. At this time, as... Figure 1 As shown, the peeling start portion 30 of the protective sheet 28 is arranged to extend toward the middle portion 34 on the side 36d side of the main body receiving portion 36.

[0045] The peel-off starting portion 30 of the protective sheet 28 is a part that is easily torn off when the medication dispensing device 12 is removed from the packaging container 10, and is a part of the medication dispensing device 12 that needs to be protected when opened. If the protective sheet 28 is peeled off when opened, the adhesive surface 24b is not protected, the adhesive strength is reduced, and there is a possibility that the medication dispensing device 12 may fall off the patient's skin during use. The peel-off starting portion 30 is a part that the user can easily pull when removing the medication dispensing device 12 from the packaging container 10. The protective sheet 28 is attached to the frame attachment 24 with a relatively weak adhesive strength, so if the user pulls on the peel-off starting portion 30, the protective sheet 28 will peel off before the medication dispensing device 12 is removed from the packaging container 10. Therefore, the peel-off starting portion 30 is a part that needs to be protected when removing the medication dispensing device 12 from the packaging container 10.

[0046] like Figure 1 As shown, the sealing film 18 is formed into a rectangular shape with the same dimensions as the container body 16. The sealing film 18 is formed, for example, from a thin, transparent film made of polyethylene resin or the like. The sealing film 18 is adhered to the adhesive portion 32 of the container body 16 in a peelable manner.

[0047] like Figure 4 As shown, the sealing film 18 extends along the adhesive portion 32 and is adhered to the adhesive portion 32 at the sealing portion 44, which is formed in a manner that surrounds the entire circumference of the recess 14. With the sealing film 18 and the adhesive portion 32 overlapping, the sealing portion 44 can be formed by clamping it with a mold of a predetermined shape and heating it locally to melt it.

[0048] The adhesive force per unit area of ​​the sealing portion 44 is constant. It should be noted that the sealing portion 44 in this embodiment is provided with: a difficult-to-peel portion 46, which is formed wide over the entire width of the adhesive portion 32 (the distance between the interlayer portion 34a and the outer periphery 32a); and an easy-to-peel portion 48, which is formed by linear patterns 48a, 48b that are narrower than the width of the adhesive portion 32.

[0049] The difficult-to-peel portion 46 is bonded to the adhesive portion 32 with a wide adhesive area, thus bonding with a higher adhesive force than the easy-to-peel portion 48, making it more difficult to peel off compared to the easy-to-peel portion 48. The difficult-to-peel portion 46 is C-shaped along the adhesive portion 32 of the peeling start portion 30 surrounding the protective sheet 28 of the liquid dispensing device 12.

[0050] The easy-peel portion 48 is bonded to the adhesive portion 32 with a narrower width compared to the adhesive portion 32. Compared to the difficult-to-peel portion 46, the bonding area is narrower, and the bonding force is relatively weaker. Therefore, the easy-peel portion 48 can be easily torn off compared to the difficult-to-peel portion 46. The easy-peel portion 48 has two parallel linear patterns 48a and 48b. These linear patterns 48a and 48b include straight portions 49a and curved portions 49b connecting adjacent straight portions 49a.

[0051] Of the two linear patterns 48a and 48b, linear pattern 48a is formed on the inner side, and linear pattern 48b is formed on the outer side. The two linear patterns 48a and 48b are arranged with a gap of constant width to ensure that the other is not affected even if one is peeled off. The width of each of the linear patterns 48a and 48b can be, for example, 0.1 to 1 mm.

[0052] A bulge 52, which bends outward in an arc shape, is formed on the curved portion 49b of the outer linear pattern 48b. The bulge 52 is formed as an adhesive portion, the same as the linear pattern 48b, and becomes a part where the pulling force acting on the sealing film 18 is locally concentrated when the sealing film 18 is torn off from the edge of the packaging container 10. Because the bend is arc-shaped, even when the sealing film 18 is pulled from multiple directions, there is a part where the pulling force is locally concentrated. Therefore, compared with the case where there is no bulge 52, the sealing film 18 can be torn off more easily.

[0053] The packaging container 10 of this embodiment is constructed in the manner described above, and its function will be explained below.

[0054] In this embodiment, the packaging container 10 houses the liquid dispensing device 12 in the recess 14 of the container body 16, and provides it to the user in a state where the recess 14 and the liquid dispensing device 12 are sealed by the sealing film 18.

[0055] Before use, the user opens the packaging container 10 and removes the liquid dispensing device 12 from the container body 16. When opening the packaging container 10, firstly, the easy-peel portion 48 of the sealing film 18 is peeled off from the adhesive portion 32 of the container body 16.

[0056] In the prior art, the sealing film 18 is bonded with uniform peel strength over its entire extent, making it possible to tear off the entire sealing film 18 at once. In this case, the entire protective sheet 28 of the dispensing device 12 housed in the packaging container 10 is exposed. In this case, the peel initiation portion 30 of the protective sheet 28 is exposed as an easy-to-grip part when the dispensing device 12 is pulled out. Therefore, in order to pull the dispensing device 12 out of the container body 16, the user may pull the peel initiation portion 30. Because the protective sheet 28 can peel off from the frame attachment 24 due to its weak peel strength, the protective sheet 28 may peel off before the dispensing device 12 is removed from the container body 16, potentially compromising the protective function of the adhesive surface 24b.

[0057] In contrast, according to the packaging container 10 of this embodiment, the sealing portion 44 of the adhesive portion 32 to which the sealing film 18 is bonded to the container body 16 is provided with a difficult-to-peel portion 46 and an easy-to-peel portion 48. Since the sealing film 18 is bonded to the adhesive portion 32 across its entire width direction, the difficult-to-peel portion 46 is bonded with relatively strong peel strength, and there is no gripping portion of the sealing film 18 at the start of peeling. Therefore, the user grasps the end of the sealing film 18 from the easy-to-peel portion 48 to initiate the peeling of the sealing film 18.

[0058] A separation portion 33 is provided at the end of the container body 16 on the side that is separated from the difficult-to-peel portion 46. Since the separation portion 33 is separated from the sealing film 18 and floats up, the user can easily hold the sealing film 18. Therefore, the packaging container 10 can encourage the user to begin peeling the sealing film 18 from the part that is separated from the difficult-to-peel portion 46.

[0059] When the user grasps the end of the sealing film 18 to tear it off from the container body 16, the easily peelable portion 48 of the sealing film 18 peels off along the linear patterns 48a and 48b. Furthermore, the peeling stops when it reaches the difficult-to-peel portion 46. The difficult-to-peel portion 46 adheres the sealing film 18 to the adhesive portion 32 with strong peeling strength, thus preventing further peeling during normal operation. Therefore, the peeling of the sealing film 18 ends with the sealing film 18 covering the peeling start portion 30 of the protective sheet 28 of the medicine dispensing device 12.

[0060] Therefore, the peeling start portion 30, which is the protected part of the medicine dispensing device 12, can be protected. It should be noted that even when the sealing film 18 is not completely peeled off, the user can hold the frame 20 of the medicine dispensing device 12 with the gripping recess 42, so that the medicine dispensing device 12 can be removed from the recess 14 of the container body 16.

[0061] The packaging container 10 of this embodiment has the following effects.

[0062] This embodiment relates to a packaging container 10 for housing a drug dispensing device 12 (medical device / subject), which has a peel-off initiation portion 30 (protected object portion) that should be avoided when removing the drug and a grippable portion that can be held. The packaging container 10 includes: a container body 16 having a recess 14 and an adhesive portion 32, the recess 14 being shaped to correspond to and housing the drug dispensing device 12, the adhesive portion 32 being planar in the portion surrounding the recess 14; and a sealing film 18, which is peelably attached to the adhesive portion 32 and seals the recess 14, the sealing film 18 being bonded to the adhesive portion 32 by means of a sealing portion 44 extending along the periphery of the recess 14, the sealing portion 44 having: a difficult-to-peel portion 46, which is formed in the portion surrounding the peel initiation portion 30 (protected object portion) of the drug dispensing device 12 (medical device / received object) housed in the recess 14 and is bonded with relatively high strength; and an easy-to-peel portion 48, which is formed in the portion surrounding the grippable portion of the drug dispensing device 12 housed in the recess 14 and is bonded with relatively low strength compared to the difficult-to-peel portion 46.

[0063] According to the packaging container 10 described above, when the sealing film 18 is peeled off to open the packaging container 10, the peeling of the sealing film 18 stops due to the difficult-to-peel portion 46. Therefore, it is possible to maintain the state in which the peeling start portion 30 of the medicine dispensing device 12 is covered by the sealing film 18 for protection. As a result, when the user removes the medicine dispensing device 12 from the container body 16, it is possible to prevent the user from touching the peeling start portion 30, which is the protected part, with their hands.

[0064] Alternatively, in the above-mentioned packaging container 10, the easy-to-peel portion 48 is formed as a fine line pattern 48a, 48b, and the difficult-to-peel portion 46 is formed on the entire surface of the adhesive portion 32 surrounding the peel start portion 30 (the protected part).

[0065] In this way, by utilizing the shape of the sealing part 44 to separately form the difficult-to-peel part 46 and the easy-to-peel part 48, it is possible to prepare them simultaneously in one bonding process, thereby reducing manufacturing steps and achieving excellent productivity.

[0066] Alternatively, in the aforementioned packaging container 10, the easy-peel portion 48 serves as a sealing portion 44 and has two parallel linear patterns 48a and 48b. With this configuration, even if the sealing film 18 is about to peel off due to impact or other reasons, the peeling will stop on one of the linear patterns 48a and 48b, thus reducing the risk of accidental opening.

[0067] Alternatively, in the packaging container 10 described above, the linear patterns 48a and 48b have multiple straight portions 49a and curved portions 49b connecting the straight portions 49a, and the curved portions 49b of the linear pattern 48b have outwardly curved bulges 52. With this configuration, since the load when the sealing film 18 is pulled in the peeling direction is concentrated in the bulges 52, the peeling of the sealing film 18 can be initiated with a small force.

[0068] Alternatively, in the packaging container 10 described above, the bulge 52 is located at the bend 49b furthest from the difficult-to-peel portion 46. This makes it easier to peel off the easy-to-peel portion 48, starting from the portion of the sealing film 18 that is separated from the difficult-to-peel portion 46.

[0069] Alternatively, the packaging container 10 may include a separation portion 33 that extends from the adhesive portion 32 near the bulge portion 52 and descends in the direction of separation from the sealing film 18. With this configuration, when peeling off the sealing film 18, the user can easily hold the sealing film 18 and easily peel it off.

[0070] The object housed in the aforementioned packaging container 10 is a medication dispensing device 12 that is attached to the body. The medication dispensing device 12 may also have: a box-shaped frame 20; a frame attachment 24, which is formed to be larger than the frame 20 and has an adhesive surface 24b for attaching the frame 20 to the patient's body; and a protective sheet 28 that covers the adhesive surface 24b of the frame attachment 24 and has a peel-off starting portion 30 at one end that is separate from the frame attachment 24. Alternatively, the medication dispensing device 12 may be housed in a recess 14 of the container body 16 of the packaging container 10 with the protective sheet 28 facing the sealing film 18, and a difficult-to-peel portion 46 may be formed in the adhesive portion 32 surrounding the peel-off starting portion 30 of the protective sheet 28.

[0071] According to the above configuration, when the liquid dispensing device 12 is removed from the container body 16, the peeling start portion 30 of the protective sheet 28 can be protected.

[0072] (Second Implementation)

[0073] like Figure 5A and Figure 5BAs shown, the packaging container 60 of this embodiment is a container for packaging a pre-filled syringe 62 (medical device). The packaging container 60 includes a container body 64 formed of a resin sheet and a sealing film 66 that seals the container body 64. The container body 64 is formed of a transparent thick resin sheet made of PET resin or the like, and a recess 68 formed by vacuum forming or the like is formed in its center. The recess 68 is formed in a shape corresponding to the pre-filled syringe 62, and the entire pre-filled syringe 62 can be accommodated in the recess 68. A planar adhesive portion 70 for bonding the sealing film 66 is formed on the outer periphery of the container body 64.

[0074] The sealing film 66 and the adhesive portion 70 are bonded in a manner that allows them to be peeled off at the sealing portion 72 of a predetermined shape. In this embodiment, the front end of the pre-filled syringe 62 is the part to be protected. Therefore, the adhesive portion 70 surrounding the front end of the pre-filled syringe 62 has a difficult-to-peel portion 74, while the other portions have easy-to-peel portions 76. The difficult-to-peel portion 74 is bonded to the entire surface of the adhesive portion 70 surrounding the front end of the pre-filled syringe 62 to form the sealing film 66. The easy-to-peel portion 76 is formed as a narrow linear pattern 78.

[0075] In the packaging container 60 of this embodiment, the user can also peel the sealing film 66 from the easy-peel portion 76. Furthermore, the peeling of the sealing film 66 by the user stops at the difficult-to-peel portion 74. Thus, the sealing film 66 remains in a state covering the front end (protected area) of the pre-filled syringe 62. When the user removes the pre-filled syringe 62 from the container body 64, it prevents the user's hand from contacting the front end of the pre-filled syringe 62.

[0076] The present invention has been described above with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention.
