Description

  The present invention relates to a dressing material package in which a dressing material used in the medical field and the hygiene field is sealed in a bag, and a method for opening the dressing material package. In particular, the present invention is easy to open and after opening It is related with the dressing material package excellent also in the ease of taking out the dressing material, and the opening method of a dressing material package.

  Dressing material is a sheet-like medical device for application to damaged parts of the skin, such as burns, scratches, ulcers, wounds, and surgical incisions such as catheter insertion parts. This prevents the invasion of the skin and keeps it clean and maintains the affected area in a moderately moist state, thereby demonstrating the effect of accelerating healing.

  Therefore, it is necessary to package the dressing so that it can be sterilized from the time of manufacture to the time of use and can be easily taken out during use.

  Therefore, the present inventors maintain a sanitary condition by sealing the dressing material until use, and as a packaging method that can be easily opened, a packaging method in which an incision means for opening is provided on the outer periphery of the heat seal bag body Was applied to dressing packaging.

  In this packaging method, the dressing material is sealed by heat-sealing around the dressing material sandwiched between the packaging films to form a bag body, and a straight notch (I notch) or V-shape is formed on the outer periphery of the bag body. An incision means such as a notch (V notch) is provided to form a dressing material package.

  Then, when opening these dressing material packages, the dressing material is cut by cutting to the opposite sides of the bag body so that the opening line does not get caught with the dressing material inside the bag body based on the incision means. It can be taken out.

  However, when the bag is opened by this method, the dressing material remains in the bag body without being exposed from the bag body after opening, and in order to take out the dressing material, put a finger on the opening of the bag body. There was a problem that it was difficult to take out the dressing material by putting it in.

Regarding the opening of the heat-sealed package by such an incision means, as a technique for improving the take-out property of the package, the bag body is opened by the incision means and a part of the bag body is removed, and the opening portion is removed. A method for exposing a part of an object to be packaged has been proposed, and the object to be packaged can be easily taken out by using the exposed part as a handle. (For example, Patent Document 1)
However, with this method, it may be difficult to open the opening line because it is caught by the packaged object at the time of opening, and if you try to open the bag forcibly from this hooked state, the opening line will be bent sideways. There was a risk that a sufficiently large opening could not be formed, and the packaged item could be damaged by the shearing force at the time of opening.

  When such a damage occurs in the dressing material, there is a concern that microorganisms may invade from the damaged portion, so there is a problem in applying this unsealing method to the dressing material as it is.

Also, as an opening method that can be opened without damaging the package, the package is a heat-sealed bag body having an incision means on the outer periphery, and the package to be carried carried on the fixing resin sheet is sealed and fixed There has been proposed a method of providing one or more convex portions at the outer end portion of the resin sheet and in the vicinity of the incision means. (For example, Patent Document 2)
According to this method, when the bag body is opened from the incision means provided on the outer periphery of the package body, the protrusions reduce the catch between the opening line and the fixing resin sheet, and can be opened cleanly. By using the convex portion as the handle, it is said that the packaged item fixed to the fixing resin sheet can be easily taken out.

  However, this method has the effect of reducing the catch between the opening line and the fixing resin sheet and making it easier to open, but if the opening line does not hit the convex part, the fixing resin sheet is exposed from the bag. In many cases, the finger must be picked up from the opening of the bag by a finger.

Further, the fixing resin sheet used in this method is discarded after being taken out, and it is not preferable to use such a member from the viewpoints of waste reduction and product cost reduction.
JP 2000-157333 A (Claim 5) JP 2001-335064 A (Claim 1)

  The present invention has been made to solve such a problem, and the packaging body can be opened reliably and easily, and after the opening, the dressing material is reliably exposed from the bag body. It aims at providing the dressing material package which exhibits.

  In addition, the present invention provides a method for opening the dressing material packaging body, which can surely and easily open the packaging body, can reliably expose the dressing material to the outside of the bag body after opening, and exhibits excellent takeout properties. It is intended to do.

  The present invention provides a dressing material having a pressure-sensitive adhesive layer for skin application on one side of a base material and a separator having a size substantially the same as that of the pressure-sensitive adhesive layer on the surface of the pressure-sensitive adhesive layer. A dressing material package that is hermetically sealed, wherein the dressing material has a quadrangular shape as a basic shape, and is a shape obtained by cutting off at least one of the four corner portions. Is 65 to 85% of the plane area inside the bag body, and the bag body incision means is provided at the bag outer peripheral position adjacent to the portion where the corners of the dressing material are cut off. It is related with the dressing material package characterized by the above, and it has been found that the above-described problems can be solved by adopting such a configuration.

Further, the present invention provides a rectangular bag made of a packaging film having a pressure-sensitive adhesive layer for skin application on one side of a base material, and a dressing material comprising a separator having a size substantially the same as that of the pressure-sensitive adhesive layer on the surface of the pressure-sensitive adhesive layer. A method of opening a packaging body in which a dressing material having a shape obtained by cutting off at least one corner of a square of a dressing material package sealed with a body is sealed in a rectangular bag body, the corner of the dressing material on the outer periphery of the bag body In the middle of opening from the incision means provided at the position adjacent to the cut-off portion to the opposite side of the bag body, the opening line is crossed with the cut-off portion of the dressing material. It is related with the opening method of the dressing material packaging body to perform, By opening the dressing material packaging body of this invention by such a method, dressing material easily and reliably Sokarada be opened, also dressing is reliably exposed to the bag body outside after opening, it has been found to become excellent in removability.

  The dressing material of the present invention is provided with an incision means at a position adjacent to a portion where the corner of the dressing material is cut off on the outer periphery of the bag body. By reliably crossing the outer periphery of the part from which the corners are cut off and continuing the opening operation from this intersection, on the side of one of the packaging films sandwiching the dressing material, along the shape of the outer periphery of the dressing material The opening line is bent appropriately, and the packaging film can be cut smoothly.

  On the other side of the packaging film, since the dressing material is not caught at the intersection, the packaging film is torn straight beyond the intersection and a part of the dressing material is exposed from the bag body. By using the portion as a handle, the dressing material can be easily taken out.

  By these actions, the dressing material package of the present invention can be opened smoothly without applying excessive force, and the dressing material can be easily removed by holding the exposed portion of the dressing material after opening. It can be taken out.

  The dressing material package of the present invention is a bag body formed by sandwiching a dressing material between packaging films and sealing the packaging film around the dressing material by heat sealing. Hereinafter, the dressing material package of the present invention will be described by taking the dressing material package 1 of FIG. 1 as an embodiment of the dressing material package of the present invention as an example.

  The dressing material 2 is an adhesive material having an adhesive layer for attaching to the skin on one side of a film or sheet-like substrate, and a separator for protecting the adhesive layer is provided until it is used.

  Since a general dressing material is a very thin, flexible, and non-sticky adhesive material, many of the dressing materials have poor handleability when peeled off when applied to the skin. For this reason, some dressing materials provide moderate rigidity by providing a backing material that can be peeled off on the back of the film in order to improve application operability during application.

  The present invention is suitable for the packaging of such dressing materials, and particularly when applied to the packaging of dressing materials having a backing material, not only the separator but also the rigidity of the backing material works advantageously for the opening method of the present invention. preferable.

  The dressing material 2 of the present invention has a quadrilateral shape such as a square or a rectangle as a basic shape, and has a shape obtained by cutting off at least one of the corners. The dressing material 2 of the present invention shown in FIG. 1 has a shape in which one of the four corners is cut off, and the main part of the portion 3 from which the corners are cut out is constituted by a straight line. The end corresponding to the upper side is a curve.

  The reason for limiting the shape of the dressing material 2 in this way in the present invention is to moderately limit the movement of the dressing material 2 in the bag 4.

  If the purpose is simply to seal the dressing material 2, the shape of the dressing material 2 need not be limited in this way.

  However, the object of the present invention is to provide a dressing material package 1 that not only seals the dressing material 2 but also has excellent unsealing and removal properties. For this purpose, the corners of the dressing material are cut off. The relative positional relationship between the portion 3 and the incision means 5 provided in the bag body 4 is important.

  In order to maintain such a positional relationship, a configuration in which the dressing material 2 can freely move in the bag body 4 is not preferable, and the movement range of the dressing material 2 in the bag body 4 is limited to some extent. In addition, it is preferable that the structure be less susceptible to rotation or tilting.

  As described above, the dressing material 2 of the present invention has a quadrilateral shape such as a square or a rectangle as a basic shape, and has a shape obtained by cutting off at least one of the four corners of the quadrilateral. Then, the size of the portion 3 from which the corners of the dressing material are cut off may be arbitrarily determined in consideration of the balance between the size and shape of the dressing material 2 and the bag body 4 and the dressing material package 1 as a whole. In particular, it is preferable to determine the shape in consideration of the following points.

  As an example of the shape of the part 3 where the corner of the dressing material is cut off, any two points on the two adjacent sides are connected by a straight line, and the corner shown in FIG. Connect any two points on the two sides with a curve, cut off the corners along that line, and the shape shown in Fig. 3, or any two points on the two adjacent sides, a straight line or a curve Examples include a shape as shown in FIG. 4 that is connected by a combined line and cuts corners along the line.

  If the portion 3 from which the corners of the dressing material are cut off has such a shape, the line connecting the two adjacent sides is inclined with respect to the side where the incision means 5 of the bag body 4 is provided. The virtual line 6 in the opening direction and the portion 3 where the corner of the dressing material is cut off are oblique.

  As a result, when opening along the imaginary line 6 from the incision means 5 and when the outer peripheral line of the portion 3 where the corner of the dressing material is cut off and the opening line 7 intersect, the opening of the dressing material is advanced when the opening is advanced from the intersection. The opening line 7 is bent along the outer peripheral line of the portion 3 where the corners are cut off, and the opening line 7 can be smoothly opened without being caught by the dressing material 2.

  Among such shapes, it is preferable to configure the portion 3 in which the corners of the dressing material are cut off by a line that combines a straight line and a curve, for example, the corners of the dressing material as in the shapes shown in FIGS. It is preferable that most of the portion 3 cut off is formed with a straight line, and at least the end portion on the side in the opening direction is formed with a curve, and is smoothly connected to the outer peripheral side of the dressing material 2.

  If it does in this way, in the straight part which occupies most of the part 3 which cut off the corner of the dressing material, the opening line 7 will cross at a uniform angle at any position. At the point of intersection, the opening line 7 is appropriately bent and is not caught on the dressing material 2, and when the end of the portion where the corner is further cut off is reached, the outer periphery of the dressing material 2 is curved, The opening line 7 is smoothly bent along the outer periphery of the dressing material 2, and can be smoothly opened in the side direction.

  On the other hand, as shown in FIG. 5, in the packaged body in which the rectangular dressing material 2 whose corners are not cut off is sealed, the outer peripheral line of the dressing material 2 intersects with the virtual line 6 at an angle or near an orthogonal angle. , The dressing material 2 and the opening line 7 are caught at the intersection, and the dressing material 2 may not be completely opened or may be damaged.

  In the dressing material packaging body 1 of the present invention, in order to perform the opening operation more smoothly and to expose the dressing material 2 having an appropriate area for improving the take-out property after opening from the bag body 4, the corner of the dressing material is used. It is preferable that the intersection angle 8 between the outer peripheral line of the portion 3 cut off and the virtual line 6 is within a specific range.

  In addition, when the outer peripheral line of the part 3 where the corner of the dressing material is cut off and the imaginary line 6 intersect, an acute angle and an obtuse angle are generated on both sides across the imaginary line 6, but the intersection angle 8 referred to in the present invention is an acute angle. It is what you point to.

  Moreover, in the case of FIG. 3 where the shape of the intersection portion of the portion 3 where the corner of the dressing material is cut off is a curve, among the angles formed by the tangent line 9 passing through the intersection point and the virtual line 6 The acute angle is defined as an intersection angle 8.

  In the present invention, it is preferable to determine the shape of the portion 3 from which the angle of the dressing material is cut off so that the crossing angle 8 is 20 to 80 degrees, and further, the angle of the dressing material is set so as to intersect at 30 to 60 degrees. It is preferable to determine the shape of the cut-off portion 3.

  In this way, when opening along the imaginary line 6 from the incision means 5, when the outer peripheral line of the dressing material 2 and the opening line 7 intersect, the opening line 7 is smooth along the outer peripheral line of the dressing material 2. The bag 4 can be cut with a smaller force.

  On the other hand, when the crossing angle 8 exceeds 80 degrees as shown in FIG. 6, when the outer peripheral line of the dressing material 2 and the opening line 7 intersect, the opening line 7 is caught by the dressing material 2 and the opening line is opened. 7 becomes difficult to bend smoothly, and as a result, an extra force is required for opening.

  On the other hand, when the crossing angle 8 is less than 20 degrees as shown in FIG. 7, the opening line 7 is not caught by the portion 3 where the corner of the dressing material is cut off and can be easily opened. However, in this case, the dressing material 2 is hardly exposed from the bag 4 after opening, and the effect of improving the take-out property of the dressing material 2 is poor compared to the case where the crossing angle 8 is 20 degrees or more.

  When determining the shape of the dressing material 2, it is preferable to consider at which position in the dressing material package 1 the portion 3 where the corners of the dressing material are cut off and the opening line 7 intersect. .

  In the present invention, it is important to ensure that the opening line 7 intersects the portion 3 where the corners of the dressing material are cut off. For this purpose, as shown in FIG. It is preferable that the imaginary line 6 intersects the portion 3 where the corner of the dressing material is cut off at a position less than ½ of the distance 10 (L) connecting to the side to be cut.

  FIG. 8 shows the dressing material package 1 shown in FIG. 1 which is an embodiment of the present invention, and the square area of the basic shape of the dressing material 2 is relative to the plane area inside the bag body 4. About 70%. In the dressing material package 1, the outer peripheral line of the dressing material 2 and the unsealing line 7 intersect at any position regardless of the position of the dressing material 2 in the bag body 4.

  The distance from the incision means 5 to the outer peripheral line of the portion 3 where the corner of the dressing material is cut off is less than ½ of the distance 10 (L) connecting the incision means 5 to the opposite side of the bag body 4. In the case shown in FIG. 8 where the shape of the dressing material 2 is determined, since the distance between the incision means 5 and the portion 3 where the corner of the dressing material is cut off is short, the unsealing line 7 is surely crossed at the target position. Can be made.

  On the other hand, in the case of FIG. 9 where the outer peripheral line of the portion 3 where the corner of the dressing material is cut off and the virtual line 6 intersect at a distance farther than this, it is easy to cut to the target position as long as the normal opening operation is performed. However, when the opening operation is performed in a rough manner, the opening line 7 may be shifted in an unintended direction while the bag body 4 is being torn, and in such a case, the opening line 7 is not the dressing material. In some cases, the exposed portion of the dressing material 2 becomes smaller than the original, and the handle at the time of taking out becomes small.

  In the present invention, not only the shape of the dressing material 2 but also its size is important, and the flat area of the quadrangle 11 that is the basic shape of the dressing material 2 is 65 to 85% of the flat area inside the bag body 4. The size is preferably 65 to 75%.

  If it is such a range, even if the dressing material 2 is moved or inclined, the angle of the dressing material is cut off by appropriately restricting the movement, inclination, and rotation of the dressing material 2 inside the bag body 4. It becomes easy to cross the part 3 and the opening line 7.

  On the other hand, when the flat area of the quadrangle 11 which is the basic shape of the dressing material 2 is less than 65% with respect to the flat area inside the bag body 4, a range in which incision means can be provided for the following reasons. 12 becomes narrow and it becomes difficult to provide the incision means 5 at a position where the portion 3 where the corner of the dressing material is cut off and the unsealing line 7 surely intersect.

  In the dressing material package 1 of the present invention, it is necessary to provide the incision means 5 so as to be adjacent to the portion 3 where the corners of the dressing material are cut off. Therefore, the incision means 5 is provided between the lower end of the dressing material when the dressing material 2 is located at the upper end of the bag body 4 and the upper end of the dressing material when the dressing material 2 is located at the lower end of the bag body 4. It will be.

  And when the plane area of the quadrangle 11 which is the basic shape of the dressing material 2 is less than 65% of the plane area inside the bag body 4, this range becomes very narrow. The degree of freedom becomes very small.

  For example, FIG. 10 shows a case where the flat area of the quadrangle 11 which is the basic shape of the dressing material 2 is 64% with respect to the flat area inside the bag body 4. In this case, the position 12 where the incision means can be provided is Although there is only a small range near the center of the bag body 4, if the incision means 5 is provided at such a position, in order to open the opening from the incision means and bend the opening line sufficiently as in the present invention, dressing The part 3 where the corners of the material are cut off must be taken large.

  However, if the portion 3 from which the dressing material is cut off is made larger, the dressing material 2 is more likely to be inclined and rotated in the bag body 4 and the opening line 7 can be crossed at the target position. It becomes difficult.

  Further, when the dressing material 2 is elongated as shown in FIG. 11 in order to take a large position for providing the incision means 5, the moving distance is limited, but the dressing material 2 is within the bag body 4. In order to increase the degree of freedom of tilting and rotation, it is necessary to consider tilting 13 to the right or tilting 14 to the left, which makes it difficult to determine the range in which the incision means 5 is provided.

  On the other hand, when the flat area of the quadrangle 11 which is the basic shape of the dressing material exceeds 85% with respect to the flat area inside the bag body 4, the movement of the dressing material 2 inside the bag body 4 hardly becomes a problem. It can be easily opened by performing a normal opening operation. However, if the opening operation of the dressing material package 1 is performed roughly, when the opening wire 7 is bent along the portion 3 where the corner of the dressing material is cut off, the opening wire 7 is heat-sealed on the side. The portion 15 is rarely cut, and in this case, it is impossible to provide the opening 16 that is large enough to take out the dressing material 2.

  For example, in the case of the dressing material package 1 of FIG. 12 in which the flat area of the quadrangle 11 which is the basic shape of the dressing material is 86% with respect to the flat area inside the bag body 4, The unsealing line 7 bent at the portion 3 from which the corners are cut off is torn to the side heat seal portion 15 by the force of unsealing, and the opening 16 as shown in FIG. 13 is formed.

  And since this opening part 16 is small with respect to the size of the dressing material 2, in order to take out the dressing material 2 in the bag body 4, it is necessary to open the bag body 4 again using a bag etc. FIG.

  Further, when the dressing material 2 is so large with respect to the plane area inside the bag body 4, the gap between the outer periphery of the dressing material 2 and the heat seal portion 15 of the bag body 4 becomes very narrow. When the position of the material 2 is shifted, the heat sealing process may be performed while the dressing material 2 is sandwiched, which may increase the defective product generation rate.

  Next, the bag body 4 will be described. The bag body 4 of the present invention is for sealing the dressing material 2, the dressing material 2 is sandwiched between packaging films, and the packaging film around the dressing material is heat sealed to form a bag shape.

  As a packaging film, a film having a good balance between hermeticity and heat-sealing property, for example, a polymer such as polyethylene, Surlyn, an ethylene-vinyl acetate copolymer, an ethylene-vinyl alcohol copolymer, or an acrylic polymer is used. A plastic film or a laminate of these is used.

  If the packaging film is too thin, the strength is too small to be suitable for hermetic packaging. On the other hand, if the packaging film is too thick, it is difficult to tear, so in order to balance strength and ease of tearing in a balanced manner, The specific thickness is preferred.

  Although it depends on the layer configuration and the type of material, a packaging film with a thickness of 10 to 200 μm can be used normally, and if a film with a thickness of 20 to 100 μm is used, it has good tearability while maintaining sufficient strength. A bag can be manufactured. If a packaging film having a thickness of about 25 to 50 μm is used, it is preferable because a packaging body having a very excellent balance of these characteristics can be obtained.

  Although the packaging film can be used as it is for heat-sealing packaging after film production, in the present invention, it is preferable to use a film stretched in a uniaxial or biaxial direction, particularly a uniaxially stretched film, and the stretching direction and the direction of tearing the bag body. It is preferable to perform packaging so that the two are the same.

  With such a configuration, when the bag body 4 is opened, the straightness of the unsealing line 7 is increased, and as a result, the bag can be opened straight from the incision means without being particularly conscious at the time of opening. And the bag body 4 can be reliably opened to the outer peripheral line of the part 3 which cut off the corner of the dressing material.

  An incision means 5 is provided on the outer periphery of the dressing material package 1, that is, on the outer periphery of the bag body 4. As the incision means 5, a straight cut (I notch) or a V-shaped cut (V notch) may be provided, or the strength of a part of the outer peripheral portion may be lowered so that the cut can be made.

  The position where the incision means 5 is provided is a position adjacent to the portion 3 where the corners of the dressing material are cut off.

  The “position adjacent to the portion 3 where the corner of the dressing material is cut off” is adjacent to the portion 3 where the corner of the dressing material is cut off while the dressing material 2 is in close contact with one side of the bag body 4. The bag body 4 that always faces the portion 3 where the corner of the dressing material is cut off, regardless of the position of the dressing material 2 in the bag body 4. It means the position on the outer periphery of.

  In order to provide the incision means 5 at such a position, a candidate position 17 for providing the incision means 5 is set at an arbitrary position on the outer periphery of the bag body 4. And even if the virtual line 6 that faces in the opening direction from there moves the dressing material 2 to any position in the bag body 4 or tilts or rotates, the virtual line 6 cuts off the corner of the dressing material. If the incision means 5 is provided at the candidate position 17 as long as it intersects with the outer peripheral line of the portion 3, the dressing material package 1 of the present invention can be manufactured.

  FIG. 14 and FIG. 15 are diagrams for explaining this. These are the same configurations as the dressing material package 1 of FIG. 1 which is one embodiment of the present invention, and have candidate positions 17 on the outer periphery of the bag body 4 facing the portion 3 where the corners of the dressing material are cut off.

  In this dressing material package 1, an imaginary line 6 that extends from the candidate position 17 in the opening direction intersects the outer peripheral line of the portion 3 in which the corner of the dressing material in the dressing material package 1 is cut off. And even if this dressing material 2 moves in the bag 4 as shown in FIG. 14 and is located, for example, in the upper right corner 18 or the lower left corner 19 of the package, the virtual line 6 indicates the corner of the dressing material. The cut-off portion 3 intersects, and no matter what position the dressing material 2 is, the virtual line 6 and the outer peripheral line of the portion 3 cut off the corner of the dressing material intersect.

  Furthermore, since this dressing material package 1 satisfies the constituent requirements of the present invention for both the shape and size of the dressing material 2 in the bag body 4, the dressing material 2 is appropriately rotated in the bag body 4. As shown in FIG. 15, even if the dressing material 2 is inclined in the left direction 20 or the right direction 21 in the bag 4, the outer circumference of the portion 3 where the corners of the virtual line 6 and the dressing material are cut off. Lines intersect and can be opened well.

  Therefore, if the incision means 5 is provided at the candidate position 17, the dressing material package 1 of the present invention can be manufactured.

  The dressing material package of the present invention has been described above by taking the dressing material package shown in FIG. 1 as an example. However, the present invention is applicable not only to the dressing material having the structure shown in FIG. 1 but also to dressing materials of various shapes. It goes without saying that it can be done.

  For example, if the portion 3 from which the corner of the dressing material is cut off is provided not only at the corner facing the incision means 5 but also at the remaining corner, it can be formed into a variety of shapes as compared with the case where it is provided at one corner, It will be excellent in aesthetics and increase product value.

  As an example of such a dressing material package, FIGS. 16 to 18, which are provided with a corner 3 adjacent to the incision means 5 and a portion 3 in which a corner of the dressing material is cut off at the corner adjacent to the incision means 5.
