Description

  The present invention relates to a blister pack, and more particularly, a blister for food, cosmetics, pharmaceuticals, etc., which can accommodate a small amount of packages of various properties such as liquid, gel, solid, etc. Regarding the pack.

  Conventionally, as a technology related to blister packs that can accommodate a small amount of packages such as liquids, gels, solids, etc., such as packaged foods, cosmetics, pharmaceuticals, etc. Patent applications such as Document 1 have been filed. In the invention according to Patent Document 1, as described in claim 1, “a storage portion comprising a storage portion main body and a stick-like protrusion continuous with the storage portion main body by molding a thermoplastic sheet is provided. A blister pack in which a sheet body is heat sealed with a cover made of an adhesive film after the contents are stored in the provided sheet body, and the heat sealing of the sheet body and the cover is on the periphery of the storage portion of the sheet body A heat-sealed seal with a ring-like linear seal on the entire circumference of the provided flange, and a half-cut line from the outside to the inside of the seat body in a direction substantially perpendicular to the projection between the projection and the linear seal Is provided. ”

Since the invention according to Patent Document 1 is formed in a special shape provided with a stick-like protrusion that is continuous with the storage portion main body, the linear seal also has a special shape in a planar shape as shown in FIG. However, many blister packs that can accommodate a small volume of this kind, foods, cosmetics, pharmaceuticals, etc. are generally formed in a planar circular shape. That is, as shown in FIGS. 6 and 7, this type of conventional blister pack is composed of a pack body 1b for storing contents and a lid member 3b for closing the pack body 1b. Since the lid member 3b is formed in a substantially circular plane shape, the flange portion 5b serving as a seal portion is also formed in a planar circular shape around the storage portion 4b. And the holding part 6b is formed in the one side edge side of the flange part 5b.

However, regardless of the shape, the lid member 3b needs to be easily peelable from the pack body 1b. This point is also disclosed in [0002] and [0003] of Patent Document 1. That is, as a general technique of this type, [0002] states that “a packaging body such as a blister pack containing a small volume of liquid material, for example, by thermoforming a thermoplastic sheet and filling the contents, There is a milk potion pack that is heat sealed and trimmed one by one to make a single package for one person.This potion pack generally has a half cut on the picking part. After the part is folded at the half-cut part, it is opened by pulling off the cover material slightly by pulling the lid, and liquids such as milk are poured out. "[0003] States that “for this reason, the sheet body and the lid member need to be heat sealed so as to have easy peelability”.

In order to heat-seal the lid material to the pack body so as to have such an easy peelability, it is desirable that the lid material be sealed to the pack body only at a predetermined sealing position and not sealed at other positions. .

However, in this type of blister pack, as described in Patent Document 1 above, heat sealing, that is, the lid material is sealed by being heated and sealed to the pack body (sheet body).
There is a risk of sealing at a position other than a predetermined sealing position. For example, in the case of the blister pack shown in FIGS. 6 and 7, there is a possibility that the edge 11 in the grip portion 6b is sealed with the lid member 3b at a position other than the flange portion 5b. In particular, this type of blister pack is formed by forming a large number of contents storage portions in a synthetic resin sheet formed in advance in a sheet shape, filling the storage portions with the contents, and then closing with a sheet-like lid material. Since the lid material and the synthetic resin sheet are manufactured by punching into a circular shape or the like having a desired shape, the edge 11 and the lid material 3b in the gripping portion 6b as described above are inadvertently sealed especially during the punching. There is a risk of being.

  And since the edge 11 in such a holding part 6b is the position which becomes the starting point of opening from the first, when the edge 11 in this holding part 6b is sealed with the lid | cover material 3b, the lid | cover material 3b will be attached to the pack main body 1b. There is a problem that it cannot be easily peeled off.

JP 2002-179140 A

The present invention has been made to solve such a problem, and the edge of the grip portion of the pack body is inadvertently sealed to the lid material when the lid material and the pack body are punched. It is an object of the present invention to provide a blister pack that does not impair easy peelability.

  The present invention has been made to solve the above-mentioned problems, and has a structure in which a sealing flange portion 5 is provided on the periphery of the opening portion 2 and a grip portion 6 is extended on one side edge side of the flange portion 5. In the blister pack comprising the pack body 1 and the lid member 3 that is sealed by the flange portion 5 of the pack body 1 and closes the opening 2, the lid member 3 in the grip 6 of the pack body 1 The blister pack is characterized in that a protrusion 7 is formed on the contact surface side of the lip.

The protrusion 7 is preferably formed integrally with the grip portion 6 of the pack body 1. The pack body 1 is formed, for example, in a substantially oval shape so that one end in a plan view draws a substantially circular curve and the other end draws a substantially elliptic curve. Further, the pack body 1 is formed so that the deepest portion 8 in the housing portion is in a position eccentric to the grip portion 6 side than the center of the housing portion.

  The blister pack of the present invention, as described above, includes a pack body having a sealing flange portion at the periphery of the opening, and a gripping portion extending on one side edge of the flange portion, and the pack In a blister pack comprising a lid material sealed to the flange portion of the main body and closing the opening, a protrusion is formed on the contact surface side of the grip portion of the pack body with the lid material. Therefore, when punching and forming the lid member and the pack body by heating, the projections as described above are interposed between the flange portion and the lid member of the pack body. A slight gap is generated between them, and accordingly, the edge of the gripping portion and the lid member are prevented from being carelessly sealed.

Moreover, since the protrusion is formed on the contact surface side with the lid member in the grip portion of the pack body, the protrusion can be used as, for example, Braille for the visually impaired, and the display position of the opening start point and the product Names can be displayed in braille.

  In addition, since the above-described protrusion is formed on the grip portion, the above-described protrusion causes a slip prevention effect when the user grips the grip portion.

  Hereinafter, a blister pack according to an embodiment will be described with reference to the drawings.

As shown in FIGS. 1 to 4, the blister pack of one embodiment includes a pack body 1 having an opening 2 on the upper surface and a lid member 3 for closing the opening 2 of the pack body 1. ing.

  The pack body 1 is entirely made of a synthetic resin, and is formed in a substantially bowl-shaped storage portion 4 that can store the contents (packaged object) and on the outer periphery of the storage portion 4 at the periphery of the opening 2. The sealing flange portion 5 and the grip portion 6 extended to one side edge of the flange portion are configured. A plurality of protrusions 7 project from the upper surface side of the grip portion 6, that is, the contact surface side with the lid member 3. The projection 7 is integrally formed with the pack body 1 when the pack body 1 is formed.

As shown in FIG. 1, the pack main body 1 is formed in a substantially oval shape so that one end side in a plan view draws a substantially circular curve and the other end side draws a substantially elliptic curve. Further, the pack body 1 is formed such that the deepest portion 8 in the housing portion 4 is positioned eccentric to the grip portion 6 side with respect to the center of the housing portion 4.

  The lid member 3 is entirely made of a synthetic resin film and is formed in a substantially planar oval shape so as to match the pack body 1. The lid 3 is sealed at the flange portion 5.

  When the blister pack having the above-described configuration is used to wrap liquid (gel, solid, etc.) contents (packaged items), the contents 9 are stored in the pack body 1 as shown in FIG. The contents 9 are packaged and sealed in a sealed state by being housed in the part 4 and sealing the lid 3 with the flange part 5 of the pack body 1 in that state.

  More specifically, a synthetic resin sheet having a large number of the accommodating portions 4 having the above-described shape is prepared, and the contents 9 are accommodated in the numerous accommodating portions 4. The blister pack in which the contents 9 are packaged is formed by sealing the lid 3 on the peripheral flange 5 and then punching and forming the lid and the synthetic resin sheet into a desired shape that is substantially oval in the plane. Will be obtained.

  In this case, since a plurality of protrusions 7 are provided on the upper surface side of the grip portion 6, that is, on the contact surface side with the lid member 3, a gap is generated between the lid member 3 and the grip portion 6. Therefore, in the case where the lid 3 and the synthetic resin sheet are formed by punching into a desired shape having a substantially oval shape, it is suitably prevented that the edge of the gripping portion and the lid are inadvertently sealed. It will be.

  When opening the blister pack packaged in this manner, the lid 3 is lifted as shown in FIG. 5 and the seal made at the flange 5 which is the periphery of the opening 2 of the pack body 1 is peeled off. Thus, the lid 3 can be peeled off and the pack body 1 can be opened.

  And when taking out the contents from the opened pack main body 1, the gripping portion 6 is gripped, and the storage portion 4 of the container main body 1 is inclined downward with respect to the gripping portion 6, so that the content is stored in the storage portion. 4 can be easily taken out.

That is, the pack body 1 is formed in a substantially oval shape so that one end side in a plan view has a substantially circular curve and the other end side has a substantially elliptical curve as described above, and the pack body 1 is accommodated. Since the deepest portion 8 in the portion 4 is formed so as to be eccentric from the center of the storage portion 4 toward the grip portion 6, the storage portion 4 is directed downward with respect to the grip portion 6 as described above. The contents are smoothly discharged along the shape of the pack body 1 as described above.

  Therefore, for example, when the content is a gel or liquid food or drink, the content can be put in the mouth as if the pack body 1 is a spoon while gripping the grip portion 6. Even when the content is a pharmaceutical product, oral administration can be easily performed in the same manner. Furthermore, when the contents are cosmetics, it is possible to easily perform the operation of discharging the contents to the palm and attaching them to the skin or the like.

  In any case, by taking the pack body 1 as described above, the contents can be easily taken out from the storage section 4.

  Moreover, since the protrusion 7 as described above is formed in the grip portion, when the grip portion is gripped and the storage portion 4 is tilted as described above, the hand slips and the pack body is accidentally dropped. There is no such thing.

Further, the protrusion 7 formed on the grip portion can be used as Braille for visually impaired persons, and for a user with weak visual acuity, the position of the opening start point can be easily determined.

In the above-described embodiment, the pack body 1 is formed in a substantially oval shape so that one end side in a plan view has a substantially circular curve and the other end side has a substantially elliptical curve. Since the deepest part 8 in the accommodating part 4 is formed so as to be eccentric from the center of the accommodating part 4 toward the gripping part 6, the contents can be obtained by handling the pack body 1 like a spoon as described above. However, the shape of the pack body 1 is not limited to the above embodiment.

  The pack body 1 is also made of a synthetic resin such as polyvinyl chloride, polyvinylidene chloride, polystyrene or polyester, a polyolefin synthetic resin such as polyethylene or polypropylene, or a laminate or coating of two or more of these synthetic resins. It is possible to use various synthetic resin materials such as those having a multi-layer structure, and any material can be used. It is also possible to use materials other than synthetic resin, such as aluminum foil and paper.

  Further, the shape of the lid 3 is not limited to the above embodiment, and can be arbitrarily changed according to the shape of the pack body 1. Although it is desirable that the planar shape of the lid member 3 basically matches the planar shape of the pack body 1, it is not essential for the present invention to match both planar shapes.

  Furthermore, the material of the lid 3 is also a synthetic resin such as polyvinyl chloride, polyvinylidene chloride, polystyrene, polyester, a polyolefin synthetic resin such as polyethylene or polypropylene, a polyamide synthetic resin, an ethylene / vinyl alcohol copolymer, or the like. It is possible to use various synthetic resin materials such as those in which two or more of these synthetic resins have a multilayer structure by lamination or coating, and the material is not limited. It is also possible to use materials other than synthetic resin, such as aluminum foil and paper.

  Furthermore, although the shape, size, etc. of the gripping part 6 are not questioned, the gripping work is facilitated by increasing the area of the gripping part 6 as much as possible, and can be handled like a spoon as described above. In addition, there is an advantage that it is easy to handle when used by, for example, a sick person with weak hand grip.

  In addition, the use of the blister pack of the present invention is not limited to the above-mentioned food, cosmetics, pharmaceuticals, etc., and the use thereof is not questioned.
