Description

  The present invention relates to a container that is easy to open, and includes a housing member that covers an article, a cover member that has a flange portion that projects outward from an opening edge that surrounds the housing portion, and a mount that fixes the cover member at the flange portion. Is.

  A blister pack known as a packaging method in which an article is inserted into a transparent blister (bulge) that is almost shaped into an article and attached to a mount is an inexpensive packaging method, and the contained article can be observed well. At the same time, it also has a feature such as excellent protection of the contained articles. However, since this type of blister pack is strongly bonded to the mount at the flange portion of the blister, it is not easy to take out the article without damaging the packaging. The mount is often printed with usage instructions, handling precautions, and other matters. If the mount is torn or the printed part is damaged, the contents can be read and understood. The problem of being disturbed. In the conventional blister pack as described above, in order to directly adhere the blister to the mount, a material that can be adhered to the blister is selected as a mount, or the selected material is coated on the surface of the mount in advance. It was also necessary to take measures such as keeping them.

  From such a problem, a device for facilitating removal of the packaged article has been made. For example, Japanese Patent Application Laid-Open No. 2001-253470 discloses an invention in which a blister pack composed of a front mount and a back mount is provided with an opening portion surrounding a product storage portion. In this case, the mount has a double structure, Also, the blister part must be made of the same material as the mount. Japanese Patent Laid-Open No. 2006-123955 has a configuration in which a take-out line and a substantially center line provided on the mount are perforated, and the mouth is closed by the elasticity of the mount after opening. In the case of this structure, the back surface of the mount is divided by the cleaved portion, which makes it difficult to read the explanation, and there is a risk of breakage at the time of division.

  Therefore, the present inventor first developed a container having a structure in which a cover member that covers a blister, that is, an article, is heat-sealed to a mount by a flange portion and fixed using a thermoplastic film. Applied for a patent. In the above invention, since the covering member can be fixed using the flange fixing material, the opening is easy, and the flange fixing material can be peeled off without damaging the mount. However, since the flange fixing material is bonded to the mount by heat sealing, it is necessary to select a material that can be heat sealed with the flange and the surface of the mount for the flange fixing material, and a structure for carrying out heat sealing is required. An equipped packaging machine is also necessary.

JP 2001-253470 A JP 2006-123955 A

  The present invention has been made based on the above-mentioned circumstances, and the problem is that a container having a blister-like covering member that covers an article can be packaged without requiring heat sealing and is easy to open. It is another object of the present invention to provide a container that can be easily opened and that has a structure that does not cause damage to the mount during opening. Another object of the present invention is to attach the accommodating portion to the mount with a fixing film and to remove the fixing film with a minimum force. Another object of the present invention is to provide a container that can be easily opened and to which a flange fixing material can be attached by a packaging machine having a linear feed direction of articles.

  In order to solve the above-described problems, the present invention includes a housing member that covers an article, a covering member that has a flange portion that projects outward from an opening edge that surrounds the housing portion, and a mount that fixes the covering member at the flange portion. In the container having the flange portion, one surface of the flange portion is in contact with the surface of the mount, and the flange fixing material is adhered to the other surface of the flange portion and the surrounding mount surface along the direction of the flange portion. In order to attach the component to the mount, pressure bonding is performed using an adhesive sheet as a flange fixing material for bonding the flange fixing material to the other surface of the flange portion and the surrounding mount surface. As a part to be picked with a fingertip in order to peel the flange fixing material from the flange part, a protruding piece part protruding from the adhesive part with the flange part is provided on the fixing film. It shall have formed, in which took measures that (the invention according to claim 1).

  A container that is an object of the present invention includes a housing part that covers an article, a covering member that has a flange part that protrudes outward from an opening edge that surrounds the housing part, and a mount that fixes the covering member at the flange part. is there. The housing portion of the covering member includes a blister (bulge) formed in the shape of an article, has a flange portion around the blister, and the flange portion is used for fixing to the mount. The mount is not limited to paper, but paper sheet covered with plastic or metal film or sheet, plastic or metal sheet, or other similar structure including.

  The cover member is attached by adhering a flange fixing material along the direction of the flange portion to the other surface of the flange portion and the surrounding mount surface in a state where one surface of the flange portion is in contact with the surface of the mount. . The flange fixing material according to the present invention is generally elongated because it is along the direction of the flange portion. However, since the form of the flange of the covering member covering the article is various, the flange fixing material is also the flange portion. Various forms can be taken according to the form.

  When the flange portion extends over substantially the entire circumference of the opening edge, the flange fixing member also extends over substantially the entire periphery of the flange portion (the invention according to claim 2). For example, when the flange portion is a quadrangle, the flange fixing material may be a frame shape formed in a quadrangle, or may be a combination of linear sheets in a square shape, and thus the flange fixing material can take various forms. it can. Similarly, when the flange portion is circular, for example, the flange fixing member can take a ring-shaped circular frame structure.

  Attaching the cover member to the mount by bonding the flange fixing material along the direction of the flange on the other surface of the flange and the surrounding mount on the surface of the flange, with one surface of the flange in contact with the mount In order to perform the above, pressure bonding is performed using an adhesive sheet as a flange fixing material for bonding the flange fixing material to the other surface of the flange portion and the surface of the surrounding mount. Since the thermoplastic film is not heat sealed as the flange fixing material, the packaging machine does not need a heat sealing function.

An adhesive sheet is used for the flange fixing material in the present invention. An adhesive sheet is a sheet in which an adhesive is coated on a sheet, and is generally a sheet made of a cellophane, plastic, cloth, craft paper or other material coated with an adhesive mainly composed of rubber or synthetic resin. .
Although it is possible to use adhesive tapes together with the adhesive sheet, the adhesive gradually hardens after the tape is applied, and the mount is also likely to be peeled off when peeled off. The resulting adhesive sheet is more suitable.

  The base material of the pressure-sensitive adhesive sheet is generally a plastic film or sheet. In addition to films and sheets, the term indicating a thin film is called a membrane (film) or foil, and any of them can be used as a substrate. Usually, a sheet is distinguished from a sheet having a thickness of 0.25 mm or more, and a film is distinguished from a film having a thickness of less than 0.25 mm. For example, a roll-shaped object is called a film, and a sheet cut into an appropriate size is a sheet. There is also a distinction such as calling it, and it is not strict. Therefore, in the present invention, the term “sheet” is used as a general term for film-like materials including the above-described films and the like. In the present invention, the thickness of the sheet generally referred to is suitably in the range of about 0.1 to 0.8 mm.

  As a part to be picked by a fingertip to peel off the flange fixing material bonded to the flange part, a protruding piece part protruding from the adhesive part with the flange part is provided on the fixing film. Since the above flange fixing material is pressure-bonded not only to the flange part but also to the mount around the flange part, it may be said that it is peeled off from the flange part and the mount, but the present purpose is from the flange part. This is expressed because the peeling of the sheet is the main part of the explanation, and the peeling from the flange part and the peeling from the mount are performed simultaneously.

  It is desirable that the above-mentioned projecting piece has a notch at the base which serves as a means for inducing breakage so that the peeling direction of the flange fixing material substantially coincides with the direction of the flange (the invention according to claim 3). When the projecting piece is picked and peeled off, the flange fixing material is peeled off at the minimum position of the width by this cutting. In other words, when the flange fixing material has a peeling direction that coincides with the flange direction and the width of the flange fixing material orthogonal to that direction is B, the force required for peeling when the flange fixing material proceeds with the minimum B width is The smallest. In this way, the peeling work is guided by cutting. In addition, the flange fixing material can take the form of a linear adhesive tape (invention of Claim 4).

  Since the present invention is configured and acts as described above, in a container having a blister-shaped container that covers an article, the flange fixing material made of an adhesive sheet is peeled from the protruding piece part, Since it is not in the state of being bonded to the mount, it can be easily opened without fear of damaging the mount. In addition, according to the present invention, since the accommodating portion is attached to the mount with the flange fixing material and the notch is provided at the base of the protruding piece portion, the flange fixing material can be removed with a minimum force. Further, according to the present invention, the flange fixing material can be in the form of a linear adhesive tape, so that the flange fixing material can be attached by a packaging machine having a linear feeding direction of the article. There is an effect.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 is a perspective view of an easily openable container according to the present invention, in which a covering member 13 having a housing portion 11 covering an article and a flange portion 12 projecting outward from the opening edge along an opening edge surrounding the housing portion is formed into a square shape. The 1st example regarding the case where it has a planar shape is shown. The cover member 13 contacts the mount 14 at the flange portion 12 and is attached to the mount 14 using a flange fixing material 15 made of an adhesive sheet as follows.

  The flange fixing material 15 made of an adhesive sheet is formed by using a sheet material made of cellophane or polypropylene as a base material, and coating the base material with an adhesive made of a rubber or acrylic base material. In the case of the first example, it is formed by cutting out from the pressure-sensitive adhesive sheet into a square planar shape. The flange fixing member 15 of the first example is formed in a rectangular frame shape that extends over the entire circumference of the flange portion 12 because the flange portion 12 extends over substantially the entire circumference of the square opening edge. Such a flange fixing material 15 brings one surface of the flange portion 12 into contact with the surface of the mount, pressure-bonds the other surface of the flange portion 12 and the surrounding mount surface, and bonds the entire surface of the flange portion 12. Thus, the covering member 13 is fixed to the mount 14.

  The flange fixing material 15 has a projecting piece portion 17 that protrudes from an adhesive portion 16 with the mount 14 as a portion to be picked with a fingertip in order to peel from the flange portion 12 and the mount 14. In each figure, the adhesive portion 16 is shown lightly colored, but this adhesive portion 16 substantially coincides with the portion to which the adhesive is applied. However, since the adhesive is also attached to the projecting piece portion 17, the non-adhesive portion 17 a is provided on the projecting piece portion 17 shown in FIG. Provided. Two protruding pieces 17 are provided side by side on the extension of the left and right sides of the storage portion 11 so as to protrude from the mount 14, and the non-adhesive portion 17 a illustrated is a pressure sensitive adhesive for the protruding piece 17. Bonded to the surface.

  The projecting piece portion 17 has notches 18 and 19 that are guided so that the peeling direction of the flange fixing material 15 substantially coincides with the direction of the flange 12 and peels at the minimum position of the width of the flange fixing material 15. 17 at the inner and outer roots. The outer cut 18 is cut inward at the base of the projecting piece 17, and the inner cut 19 is cut outward from the inner edge of the flange fixing member 15, and the respective extension lines substantially coincide.

  Next, the opening method of the container 10 of the first example that is easy to open will be described with reference to FIG. First, when the projecting piece portion 17 is picked and lifted with a fingertip, the flange fixing member 15 can be broken from the outer cut 18 and peeled off from the adhesion between the flange portion 12 and the mount 14. At that time, the notches 18 and 19 guide the peeling direction of the flange fixing material 15 to substantially coincide with the direction of the flange portion 12. In FIG. 2A, the flange fixing member 15 is illustrated as being obliquely peeled at an angle α with respect to its minimum width direction, but this is for convenience of explanation, and α is assumed to be 45 degrees. If this is the case, a force 1.4 times as large as the minimum peel force is required, but according to the present invention, a minimum peel force of 1.0 is sufficient by guiding the peel direction.

  Thus, the flange fixing member 15 can be easily peeled to the other notches 18 and 19 with a minimum peeling force, and therefore, the three sides of the rectangular frame shape are peeled off, so that the covering member 13 is separated from the mount 14. The inside article which is not illustrated can be taken out. It is the state of FIG. In this state, the flange fixing member 15 can be completely cut off even at the inner cut portion 19 and can be removed. On the other hand, the covering member 13 is attached to the mount 14 by the fixing member remaining portion 15a on one side of the rectangular frame shape. linked.

  FIG. 4 shows a modified flange fixing member 15 ′ that can be applied to the first example of the easy-to-open container 10, which has only the outer cut 18 at the base of the projecting piece 17 inward. 1 is different from that of FIG. 1 in that it is formed so as not to have an inner cut. In this way, the flange portion 12 is not cut by the inner cut, and all four sides of the rectangular frame shape of the flange fixing material 15 can be peeled off continuously, so that the covering member 13 is completely separated from the mount 14. can do.

  The projecting piece 17 can be formed by the following method. FIG. 5 shows an example of a method for forming the flange fixing material 15. This method uses a press blade mold for the continuous film 20 to be supplied, punches out the opening 21 in which the covering member 13 is disposed, and the cut 18, and further forms the outer shape in the perforated separation portion 22 that separates from the film 20. This method is suitable for bonding the flange fixing materials 15 and 15 'with an automatic packaging machine as will be described later, and is punched at a predetermined interval and wound around a bobbin. The present invention can be applied to a method of using a film and a method of carrying out packaging together with punching at regular intervals by an automatic packaging machine. In the example shown in FIG. 5, one side surface of the horizontally long adhesive sheet material 20 is folded back and punched out with a predetermined width, and adhered to the adhesive application surface 15 b so that the non-adhesive portion 17 a overlaps the folded portion of the projecting piece portion 17. The second method is a method in which a small piece of plain paper or plastic film is pasted on the back surface of the pressure-sensitive adhesive sheet material 20 and punched out. As described above, the small piece may be pasted on the projecting piece portion 17 instead of punching out. The third method is a method of punching out the protruding piece portion 17 in the horizontally long adhesive sheet material 20 and then folding back the longer end portion to form the non-adhesive portion 17a. No. 4 is a method of applying a pressure-sensitive adhesive to the base material of the pressure-sensitive adhesive sheet except for a portion corresponding to the non-adhesive portion 17a. In the present invention, any of the above methods can be applied.

  As shown in FIG. 6, the container 10 that is easy to open according to the present invention shown in Example 1 is arranged such that an article 24 is placed on a mount 14, a covering member 13 is covered thereon, and a flange fixing member 15 is further covered. It is the exploded view which shows the state arrange | positioned in these, They are adhere | attached by the automatic packaging machine shown in FIG. 7, FIG. In FIG. 7, the mount 14 is supplied on the receiving plate 23, the covering member 13 is put on the article 24 arranged thereon, and the flange portion 12 and the surrounding mount 14 are separated one by one. The state which supplies the flange fixing material 15 which is present is shown. In this automatic packaging machine, the pressurizing member 25 is configured to be able to be raised and lowered individually for the flange portion and the mount portion, and is lowered from the upper portion to individually attach the flange fixing material 15 to the flange portion 12 and the surrounding mount 14. It is designed to be pressure bonded.

  In FIG. 8, the cover member 13 into which the article 24 is inserted is fitted into the opening 21 of the continuous film 20, and the pressure member 27 similar to the above is raised at the position of the receiving plate 26. It is an example of the method of carrying out pressure bonding. Since the mount 14 is large, it is set at a fixed position above the pressurizing members 27 and 27 using another vacuum suction device, a link chain, or the like, but the hole 28a is slightly larger than the perforated separator 22 at the fixed position. The embossed plate 28 processed with a fluororesin is disposed on the surface to open the sheet and enhance the mold release capability, isolate the mount 14 and the adhesive sheet, and the adhesive application surface 15b outside the perforated separator 22 is the mount 14 so that it does not adhere to 14.

  When the pressure member 27 is raised and the flange fixing material 13 is fixed by pressure bonding to the mount 14, the film 20 is pressed, the receiving plate 26 is moved upward or sideward, and the mount 14 is lifted up. Then, it is cut off from the film 20 at the perforated separation part 22 and is completed as the container 10 of the present invention that can be easily opened. Thereafter, the finished product is moved to the side in the supply direction, the film 20 on which the next covering member 13 is set is conveyed to a predetermined position, and the mount 14 is similarly set to the predetermined position, and the above steps are repeated. To. This method is applied not only to FIG. 8 but also to the apparatus of FIG. It is also easy to move the film 20 to the pressure member side during pressure bonding with the pressure member 27 and separate it with the perforated separator 22. 7 and 8, reference numerals 29 and 29 'denote pressure member substrates, and 29a and 29'a denote cushioning materials.

  Furthermore, a modified example of the flange fixing material will be described. FIG. 9 shows an easily openable container 30 of the second example of the present invention in which a circular flange fixing member 35 is applied to a circular covering member 33 and the covering member 33 is attached to a mount 34. The example 2 has a projecting piece portion 37 provided so as to protrude from the adhesive portion 36 with the mount 34 with an interval of about the radius of the circle. In addition, 31 is a circular accommodating part, 32 is a flange part, 38 shows a notch | incision. As is clear from this example, it can be understood that the container that can be easily opened according to the present invention can be applied to any article.

  FIG. 10 shows a modification of the first example, in which a protruding piece portion 17 ′ protruding from the bonding portion 16 with the flange portion 12 is arranged on the mount 14 so as not to protrude outside the mount. An example of The projecting piece 17 projecting outside the mount 14 may be peeled off by mischief while being displayed for sale, but this fear is reduced by using this example. In the case of the container 10 ′ of this example, it goes without saying that the shape of the pressing member is processed so that the protruding piece 17 ′ does not adhere to the mount 14. For other configurations, the reference numerals in FIG. 1 are used, and detailed description thereof is omitted.

  FIG. 11 shows a fourth example in which a fixed-width winding tape made of a readily available adhesive sheet is used in place of the punch-type flange fixing material in Example 1. In this example, in order to fix the flange portion 42 of the accommodating portion 41 having a quadrangular shape to the mount 44, a rectangular flange fixing material that covers the entire circumference of the flange portion 42 by combining a linear tape with a square frame shape. 45, 43 is a covering part, 46 is an adhesive part, 47 is a protruding piece part, and 48 is a notch. This example is suitable for a cover portion having a linear flange portion, and a device for supplying a tape-like flange fixing material 51 (see FIG. 15 and the like) to a widely used automatic packaging machine is attached. The container 40 according to the present invention can be manufactured using a slightly modified one. Further, compared with the example of FIG. 1 in which the flange fixing material 15 is formed by punching, the remaining punched portion is not wasted, so that it is particularly economical. Further, there is an advantage that the type of tape can be easily changed according to the purpose of use such as required sealing degree.

  As the tape-like flange fixing material 51, various fixing modes can be realized by selecting and combining the adhesive sheet material that is easy to adhere and the adhesive material depending on the sealing degree and the purpose of use. In that case, when it is desired to peel off from one protruding piece 47 and peel off the entire circumference, a type of flange fixing material 45 that is easy to adhere is used. Conversely, when an adhesive sheet of a type that is difficult to adhere as the flange fixing material 45 is used, the adhesion of the overlapped portion is weak and the other adhesive sheet remains without being peeled off even if it is peeled off from one projecting piece 47. The remaining overlapping portion can be used as a protruding portion in the horizontal direction.

  In FIG. 12, a tape-like flange fixing member 45 ′ made of an adhesive sheet is used to adhere to the mount 44 ′ in the three directions of the flange portion 42 ′ of the cover portion 43 ′ having the rectangular accommodating portion 41 ′. The 5th example of container 40 'of this invention is shown. Since other configurations may be the same as those in FIG. 11, reference numerals are used and detailed description is omitted. This example is preferably used for an article in which the inserted article does not require a sealing property, but it is necessary to prevent dust from entering from above in a suspended state.

  FIG. 13 shows a mount 44 ″ in the direction parallel to the left and right of the flange portion 42 ″ of the cover portion 43 ″ having the rectangular accommodating portion 41 ″ using a tape-like flange fixing member 45 ″ made of an adhesive sheet. A sixth example of the container 40 "of the present invention bonded to the above is shown. Since other configurations may be the same as those in FIG. 11, reference numerals are used and detailed description is omitted. This example is suitable for packaging long and slender articles. In the previous two examples, a general automatic packaging machine, which has been slightly modified as described above, is used to attach the covering member to the mount. When performing, it is necessary to bond the vertical direction and then change the feed direction to the right angle and bond the horizontal direction with another packaging machine, or rotate the article 90 degrees and bond the tape-like flange fixing material again However, according to the present example, this is not necessary, and only the longitudinal flange portion 42 ″ may be bonded using the flange fixing member 45 ″, so that the packaging machine can be simple.

  FIG. 14 shows a modification of the sixth example, wherein a tape-like flange fixing member 45 ″ made of an adhesive sheet is used to form a flange portion 42 ″ of a cover portion 43 ″ having a rectangular accommodating portion 41 ″. Although it has a configuration in which it is bonded to the mount 44 ″ in the left and right parallel directions, a measure is taken to prevent the protruding piece 47 from being peeled off. The container 40 ″ of this example. Is provided with an adhesive portion 47b at the outer end of the projecting piece 47 via a peeling assisting piece 47a and folded, and the rest of the configuration is the same as in the example of FIG.

  FIG. 15 and subsequent figures show an example of the operation by the automatic packaging machine for manufacturing the container 50 that can be easily opened using the flange fixing material 51 made of an adhesive sheet. In each figure, the rightmost is the setting process, then the bonding process, and then the cutting process. Since the flange fixing member 51 is stretched on the flange portions on both sides of the covering member 53, the pressing member 52 is also arranged on the front side and the other side in the drawing, and the covering member 53 located in the central bonding step is pressed. It is hidden by the member 52 and cannot be seen. While the flange fixing material 51 is being pressed by the pressing member 52, the covering member 53 and the mount 54 are set in the receiving guides 56a and 56b of the previous process. Further, a guide belt 57 having a non-adhesive structure is disposed below the pressure member 52 so as to guide the flange fixing material 51 so that the flange fixing material 51 is not bonded to the pressure member 52. .

  When the tape-like flange fixing material 51 made of an adhesive sheet is sent through the guide roller 58, the covering member 53 into which the article 24 is inserted is fitted in the same procedure as described in FIG. Then, the pressure member 52 located at the lower portion is raised to perform pressure bonding to the flange portion and the mount. When the pressure bonding operation is completed, the pressure member 52 is lowered, and the receiving guides 56a and 56b are advanced by one pitch, and the cover member 53 is carried to the next cutting step. The cutter 59a is raised in the direction of the receiving plate 59b along with the stop of the advancement, and the work of separating the flange fixing material 51 by leaving the protruding piece portion behind the lid member 53 is performed. It is the state of FIG.

  Thereafter, the cutter 59a is lowered in a direction away from the receiving plate 59b, and the pressure bonding process of the flange fixing material 51 is completed. Thereby, the container 50 of the present invention that is easy to open is obtained. At the same time, the guide roller 58 reverses, and the front end of the flange fixing member 51 is pulled back to the front end of the covering member 53 arranged in the bonding process. After the reverse rotation is stopped, the pressure member 52 starts to rise, and the paper piece of the non-bonding portion 17a is automatically set at a predetermined position, and the next covering member 53, the mount 54, etc. are set at the previous process position. Will be. This is the state of FIG. In addition, the container 50 which is easy to open is removed from the work process when it advances from the cutting process. The above operations are repeated, and in this way, an easily opened container according to the present invention can be manufactured by using a general automatic packaging machine with a slight modification. Is.

  According to the container of the present invention, the tape-like flange fixing member 15 made of an adhesive sheet can be opened by peeling, and there is no fear of peeling the surface of the mount together at that time. The external appearance of the container is not damaged and the force required to open it is small. For example, in the conventional method in which the entire circumference of the covering member is bonded to the mount, a perforation cannot be opened on the mount to prevent the entry of dust and moisture in manufacturing, so a structure that peels off from the corner is unavoidable. However, in this case, since the bond width is doubled twice as much as the root of the bond width, a force exceeding 2.8 times in total is required for the bond width of 1, and the inside of the corner is In the case of a curve, and even in the case of a circle, it requires several times as much force, so it was almost impossible to open for elderly people who do not have finger strength or who have handicap on their bodies . However, according to the present invention, only one force is sufficient from the beginning to the end regardless of whether the adhesive portion 16... Is a straight line or a curved line. Even if the adhesive force is set twice to improve the sealing performance, it can still be opened with the conventional two-thirds force.

  Conventionally, it is necessary to prepare a dedicated heat heater and packaging machine even in a small lot. However, in the case of the container of the present invention, a heater for heating is not necessary, and an expensive packaging machine is used. In addition, it can be processed manually, and can be applied to products that have given up blister packaging due to their small quantity.
