Description

  The present invention relates to an easy-open packaging body for packaging a small amount of contents such as tablets, granules, powders, liquids, pastes, etc., an apparatus and a manufacturing method for the easy-open packaging body.

  Many various packages have been proposed for packaging the contents as described above, and the blister package disclosed in Patent Document 1 is one of such packages. In the blister package of Patent Document 1, after a tablet is accommodated in an accommodating portion formed on a sheet-like bottom material, a film-like or sheet-like lid material is superimposed on a surface of the bottom material opposite to the accommodating portion. Thus, the portion where the bottom material and the lid material are overlapped is adhered to be peelable. When taking out a tablet from a storage part, it takes out by crushing the storage part in which the tablet in the package was stored, or tearing or peeling a cover material.

  However, in the case of an elderly person or a person with a clumsy hand, it is unsatisfactory to take out the tablet from the housing part of the package. For example, if the container is squeezed, the tablet is easily crushed. Moreover, there is a possibility that the tablet may be lost due to the forceful ejection. The smaller the tablet size, the greater the force required to take out the tablet, making it difficult to take out the tablet without crushing or popping out.

Two members are separated from the second base material formed in a band shape. A second member separating means, characterized by comprising a heat pressing means for heating and pressing the outer peripheral edge portion superimposed in the thickness direction of the first member and the second member.

  Further, the present invention also folds the package body into a two-folded state in which a housing part for housing the contents is formed on one side and the first member is bonded to the surface of the first member opposite to the housing part. It is a manufacturing method of an easy-open packaging body that is configured with a second member that can be opened and formed on the outer surface of the central portion of the housing portion with an opening portion that is opened in a split state along with a bending operation of the second member. The forming step for forming the accommodating portion on the first base material formed in a band shape, and the opening portion capable of being opened in a split state with respect to the outer surface of the accommodating portion formed on the first base material An opening portion attaching step for attaching the first member, a first member separating step for separating the first member on which the housing portion is formed from the first base material, and the first member having a size and shape corresponding to the first member. Two members are separated from the second base material formed in a band shape. A second member separation step of, the thermocompression bonding step of thermocompression bonding the outer peripheral edge portion superimposed in the thickness direction of the first member and the second member, and performing in this order.

According to this invention, even an elderly person or a clumsy person can be easily opened with one hand.
Specifically, in order to fold the easy-open packaging body in a folded state and open the opening part formed in the housing part of the first member in a split state, the contents accommodated in the housing part are opened in a split state. It can be easily taken out from the opening part of the storage part.

As a result, it is not necessary to crush the receiving part of the first member, or to tear or peel off the second member, and even an elderly person or a clumsy person can easily open it with one hand. Can do.
In addition, when the contents are taken out from the storage unit, it is possible to prevent the hand from touching the contents or the dirt of the hands from adhering to the contents, so that a sanitary and clean state can be maintained.

  Furthermore, with both edges of the easy-open packaging body with the fingers of the hand as the action point, the part that is folded in a double-folded state in the second member is the fulcrum, and the opening part corresponding to the force point is divided into two according to the principle of leverage It can be opened easily even with a small force. Thereby, it can prevent that a content is crushed, a content jumps out vigorously, or is lost.

  Furthermore, if the easy-open packaging body is held so that the housing portion faces upward, and the opening portion of the housing portion is opened in a split state, the contents are held in one of the storage portions divided into the split state. For this reason, it is possible to prevent the contents from jumping out or falling off.

  Furthermore, for example, when taking out contents such as viscous drugs, liquid drugs, or foods, if the easy-open packaging body is opened as described above, the contents can be surely orally spilled without spilling. Therefore, for example, it is a convenient package for an infant, a child, an elderly person, a person who needs care, etc. to orally put the contents.

  Furthermore, if the thickness of the first member in which the accommodating portion is formed is increased, it is possible to wrap a desired amount (for example, 3 g to 100 g) even with contents such as granules, powder, and liquid, for example. The size can be increased.

  Furthermore, since a commercially available package has a small area, and there are irregularities on the surface of the lid that seals the container, it is very difficult to print the display contents regarding the contents. I can't figure out what it is.

  Then, the easy-open packaging body of this invention can give the printing which can be read from both front and back in the center part of a 2nd member by comprising a 2nd member with a composite sealing material. Thereby, since the display content (a name is included) regarding a content can be displayed correctly, it can be used in comfort by reading a display content.

  The first member is made of, for example, amorphous polyethylene terephthalate (A-PET), polypropylene (PP), biaxially stretched polyester (OPET), biodegradable plastic (PLA), polycarbonate (PC), polyethylene (PE), polystyrene ( PS), PETG resin, or a single sheet or composite sheet such as cardboard or metal sheet.

  The second member is made of, for example, unstretched polypropylene (CPP), biaxially stretched polypropylene (OPP), biaxially stretched polyester (OPET), polyethylene (PE), cellulose propionate (CP), or metal (aluminum). You may comprise by the member formed with the single material or the composite material.

  In addition, you may comprise the 2nd member with the sheet | seat made from aluminum formed in thickness about 0.1-0.3 mm. Moreover, you may change the material and thickness of a 2nd member according to the kind of content, or the magnitude | size and shape of an accommodating part, for example. Further, for example, when storing contents that require gas barrier properties, moisture resistance, fragrance, etc., a sheet member or a sealing material made of a material corresponding to the characteristics and physical properties of the contents may be used in combination.

  The above-mentioned contents may be composed of, for example, tablets, granules, powders, liquids, pastes and the like. In addition, the unsealing part may be, for example, a notch formed in the accommodating part, a structure for breaking and unsealing the sealing material covering the notch, or a part corresponding to the interval between two notches formed between the members may be unsealed. It can be comprised with the structure etc. which do.

  Specifically, for example, it was disclosed in JP-T-2010-504888, JP-T-2014-533222, JP-A-2004-83120, JP-A-2006-240747, JP-A-2014-198601, and the like. You may comprise by structure.

As an aspect of the present invention, a sealing material that is broken and opened in accordance with the bending operation of the second member is pressure-bonded so as to cover the opening portion with respect to an outer surface of the housing portion on which the opening portion is formed. Also good.
The above-described sealing material may be formed of a thin foil body such as an aluminum foil, a stainless steel foil, a copper foil, an iron foil, or a resin film.

According to this invention, until the easy-open packaging body is bent to a predetermined folding angle or less, the opening portion formed in the housing portion can be reliably kept sealed.
Specifically, since the sealing material covering the opening portion formed in the accommodating portion of the first member is broken and opened along with the operation of bending the easy opening packaging body to a predetermined folding angle or less, the easy opening packaging body is Until the folding angle is equal to or smaller than a predetermined folding angle, it is possible to maintain the state where the opening portion is sealed with the sealing material.

  As a result, before the easy-open packaging body is bent to a predetermined folding angle or less, the sealing material covering the opening portion is not broken and opened, and the contents stored in the storage portion flow out to the outside. Can be reliably prevented.

Further, as an aspect of the present invention, a sealing material protection portion that protects the sealing material is formed so as to cover the entire outer surface of the sealing material with respect to at least the outer surface of the sealing material among the outer surfaces of the housing portion. May be.
You may comprise the above-mentioned sealing material protection part with a protective film, a protective layer, etc., for example. The thickness of the sealing material protection part may be formed approximately the same as the thickness of the sealing material, but it is thinner than the thickness of the sealing material if it can be broken and peeled off along with the bending operation. Or thicker. Moreover, the above-mentioned at least outer surface of the sealing material is a concept including, for example, the surface of the sealing material, or the entire surface of the first member and the accommodating portion.

According to this invention, it is possible to more reliably prevent the sealing of the opening portion by the sealing material from being released before the easy-open packaging body is bent to a predetermined folding angle or less.
Specifically, since the sealing material that covers the opening part is protected by the sealing material protection part, for example, when easily transporting or transporting a large number of easy-open packaging bodies, adjacent easy-open packaging Even if the bodies are brought into contact with each other or rubbed against each other, it is possible to prevent the easy-open packaging body from being directly brought into contact with or rubbed against the sealing material.

Thereby, while being able to prevent reliably that the sealing material which covers an opening part peels or drowns, the state by which the opening part was sealed with the sealing material can be maintained.
As a result, before the easy-open packaging body is bent to a predetermined folding angle or less, the sealing material covering the opening portion is not broken and opened, and the contents stored in the storage portion flow out to the outside. Can be prevented more reliably.

  Further, as an aspect of the present invention, a folding ruled line capable of folding the second member in a folded state is attached to a portion of the second member facing the opening portion in parallel with the opening portion. Good.

According to the present invention, the easy-open packaging body can be easily folded in a folded state.
Specifically, for example, the first member is folded in a folded state along the folding ruled line compared to the resistance given when the first member is folded in a folded state against the rigidity of the member itself. The resistance applied when bending is smaller, and the first member can be easily folded in a folded state.

Thereby, the 1st member can be easily bend | folded in the bi-fold state in which the opening part formed in the accommodating part of the 1st member is opened.
As a result, the opening part formed in the accommodating part of the first member can be reliably opened with the operation of folding the easy-open packaging body in a folded state.

  Further, as an aspect of the present invention, an auxiliary folding ruled line that assists the folding of the first member with the folding operation of the second member is provided with respect to the outer peripheral edge portion of the first member relative to the housing portion. You may attach in parallel with.

  The above-mentioned folding ruled lines and auxiliary folding ruled lines may be constituted by, for example, ruled lines having a substantially V-shaped cross section or a substantially U-shaped cross section when viewed from the first direction, or Jomon-shaped ruled lines or the like viewed from the thickness direction. Good. Specifically, for example, it was disclosed in JP2003-266532A, JP2003-292020A, JP2004-1858A, JP2004-83129A, JP2004-315073A, and the like. You may comprise by a ruled line.

According to the present invention, the easy-open packaging body can be easily folded in a folded state.
Specifically, for example, the first member is folded in a folded state along the auxiliary folding ruled line, compared to the resistance applied when the first member is folded in a folded state against the rigidity of the member itself. The resistance applied when bending is smaller, and the first member can be easily folded in a folded state.

Thereby, a 1st member can be easily bend | folded in the bi-fold state in which the opening part formed in the accommodating part is opened.
As a result, the opening part formed in the storage part can be opened more reliably with the operation of folding the easy-open packaging body in a folded state.

In addition, it is not necessary to attach an auxiliary bending ruled line to the outer peripheral part from the accommodating part in a 1st member. In this case, when the easy-open packaging body is folded in a half-folded state, it tends to return to the state before the folding by the restoring force accumulated in the folded portion of the member.
Thereby, since the opening part formed in the accommodating part of the 1st member is closed, the content accommodated in the accommodating part can also be divided | segmented into predetermined amount and taken out.

Moreover, as an aspect of the present invention, a convex raised portion protruding upward from the outer surface of the housing portion may be formed on the outer surface corresponding to the opening portion in the housing portion.
According to this invention, the opening part formed in the accommodating part of the 1st member can be opened more easily.

Specifically, when the contents are taken out from the housing portion, the swelled portion protruding from the housing portion is pressed, and the portion where the opening portion is formed in the housing portion is deformed downward so as to be recessed. The opening part formed in the part is opened in a split state in advance from the highest part corresponding to the rising part.
As a result, even if the force at the time of folding the easy-open packaging body in a folded state is weak, the opening part can be opened more easily from the angular part of the swelled part.

  According to the present invention, it is possible to provide an easy-open packaging body, an easy-open packaging body manufacturing apparatus, and a manufacturing method that can be easily opened with one hand even if the elderly person or a clumsy person is a clumsy person.

The display content (for example, a character, a design, an illustration, etc.) regarding the tablet C is printed on the surface side of the sealing material 7 (see FIG. 2).

  The adhering width of the sealing material 7 is formed in a predetermined adhering width according to the size of the accommodating portion 4. As a specific example of the adhering width, when the accommodating portion 4 is formed in a size that can accommodate a tablet C having a diameter of 8 mm and a thickness of 4 mm, it is sufficient if the adhering width of the sealing material 7 is 5 mm. Sealing effect can be obtained. The breaking strength of the sealing material 7 is set to a strength at which the easy-open packaging body 1A is broken when it is bent to a predetermined folding angle θ1 or less (see a two-dot chain line in FIG. 2).

A thin portion (for example, a groove-like ruled line or a concave portion) is parallel to the central portion of the sealing material 7 in the second direction L2 along the notch 6 formed in the accommodating portion 4 of the first member 2. You may form in.
Along with the operation of folding the easy-open packaging body 1A in a folded state, the thin portion of the sealing material 7 is broken, so that the sealing material 7 can be more easily broken and opened.

  At the center of the second member 3 in the second direction L2, the second member 3 is folded in half with respect to the second direction L2, facing the notch 6 formed in the housing portion 4 of the first member 2. A foldable bending portion 10 is formed (see FIGS. 1 and 2).

  The bent portion 10 is provided with a crease ruled line 11 having a substantially V-shaped cross section that can be folded in a folded state so that the second member 3 is folded in two, facing the notch 6 formed in the accommodating portion 4 of the first member 2.

A method of taking out the tablet C from the easy-open packaging body 1A will be described.
First, the fingers of the hand are hung on both edges of the easy-open packaging body 1A, and the container 4 side is held upward, and then both edges of the easy-open packaging body 1A with the fingers of the hand are applied. Then, with the folding part 10 folded in the two-folded state in the second member 3 as a fulcrum, the easy-open packaging body 1A starts to bend in the folding direction G in which the easy-open packaging body 1A is folded in the two-folded state according to the lever principle (FIG. 2 (a) see the two-dot chain line).

When the easy-open packaging body 1A is bent to a predetermined folding angle θ1 or less, the sealing material 7 attached to the opening region 5 of the accommodating portion 4 corresponding to the power point is broken and opened. Along with the operation of folding the easy-open packaging body 1A in a folded state, the notch 6 attached to the opening region 5 of the housing portion 4 is opened (see FIG. 3).
Thereby, the tablet C accommodated in the accommodating part 4 of 1 A of easy-open packaging bodies can be taken out from the opening part of the accommodating part 4 divided | segmented into the 2 split state.

As a result, when taking out the tablet C from the storage part 4, it is not necessary to crush the storage part 4 of the first member 1, or to tear or peel off the second member 3, and the elderly and the hands are clumsy. Even a simple person can easily open it with one hand.
And since it can prevent that a hand contacts the tablet C or the stain | pollution | contamination of a hand adheres to the tablet C when taking out the tablet C from the accommodating part 4, it can maintain a hygienic and clean state. .

  Further, according to the lever principle, the sealing material 7 attached to the opening area 5 of the housing part 4 in the first member 2 is broken and opened, and the notch 6 attached to the opening area 5 of the housing part 4 is opened. Therefore, it can be opened easily even with a small force. Thereby, it can prevent reliably that the tablet C is crushed, the tablet C jumps out vigorously, or is lost.

  Furthermore, until the easy-open packaging body 1A is bent to a predetermined folding angle θ1 or less, the sealing of the cut 6 by the sealing material 7 is not released, and the cutting 6 is sealed by the sealing material 7. Therefore, the tablet C accommodated in the accommodating part 4 can be more reliably prevented from jumping out.

  Furthermore, when the easy-open packaging body 1A is folded in a two-folded state while the container 4 is held in an upward state, the tablet C is held in one container 4 divided into two, It is possible to prevent the tablet C accommodated in the accommodating portion 4 from jumping out or dropping down (see FIG. 3).

  Furthermore, when the size of the tablet C is larger than that of the one storage portion 4 divided into two, the tablet C is more easily protruded because a part of the tablet C protrudes outward from the opening of the storage portion 4. Can be taken out.
