Description

  The present invention relates to a packaged product in which an object to be packaged is hermetically sealed by heat-sealing a packaging film.

  In general, in a packaged product in which an object to be packaged is hermetically packaged by heat-sealing a packaging film, an opening such as a notch is often provided on the outer edge of the heat-sealed portion of the outer periphery of the packaged product. With such an opening, the package can be easily opened. However, when packaging certain types of items such as pharmaceuticals and cosmetics, there is a case where it is desired to prevent erroneous opening by an infant or the like.

Japanese Utility Model No. 3073049 (Patent Document 1) discloses a misopening prevention type packaging pack in which a notch for opening is provided within a range of a seal portion so that one end of the notch is not opened outward from the outer edge of the seal portion. Is disclosed. However, as with this packaging pack, an infant or the like can casually remove a pencil or the like by simply providing a notch for opening within the range of the seal so that one end of the notch is not opened outward from the outer edge of the seal. There is a problem that using a tool can easily open the container.
Registered Utility Model Publication No. 3073049

  In view of the above, the present invention makes it difficult for an infant or the like to easily open even if a tool such as a pencil is casually used, while for adults, it is relatively easy to use without using scissors or a cutter. It is an object to provide a package that can be easily opened.

Thus, the present invention provides:
(1)
The packaged product is a packaged product that is hermetically sealed by heat sealing a packaging film,
The packaging film has a heat seal part in at least a part of the outer peripheral part of the packaged product,
The heat seal part has at least a first opening and a second opening in the middle part of the seal width,
The first opening opens from the first opening to the second opening when the heat seal part is torn, but does not substantially reach the non-heat seal part in which the packaged item is stored. Forming a first tear,
The second opening forms a second tearing part that extends from the second opening to the non-heat sealing part when the heat sealing part is torn.
A packaged product characterized by:
(2)
The package according to (1), wherein the first opening has a shape in which the first tear portion is oriented toward the second opening;
(3)
The package according to (1) or (2), wherein the second opening has a shape in which the second tearing portion is oriented toward the non-heat seal portion;
(4)
The package according to any one of (1) to (3), wherein the size of the first opening is larger than the size of the second opening; and (5)
(1) thru | or the commercial product provided with the package as described in any one of (4), and the container which accommodates this;
I will provide a.

  In the packaged product of the present invention, the opening in the middle part of the seal width of the heat seal part has at least a first opening and a second opening, and the first opening tears the heat seal part. In this case, it extends from the first opening to the second opening, but does not substantially reach the non-heat-sealed portion in which the package object is stored. As a result, since it is difficult to open the package with only the first opening, it is difficult for an infant or the like to open easily even if a tool such as a pencil is casually used.

  On the other hand, the second opening opening forms a second tearing portion that extends from the second opening opening to the non-heat sealing portion when the heat sealing portion is torn. As a result, it is possible to tear the heat seal part from the first opening, reach the second opening, tear the heat seal part from the second opening, open the package, and take out the package. If it is an adult, it is not always necessary to use scissors or a cutter, and it can be opened relatively easily.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a plan view of a packaged product according to the first embodiment of the present invention.

  The packaged product 11 is formed by sealing an object to be packaged (not shown) by heat-sealing the packaging film 12. The packaging film 12 has a heat seal portion 13 on at least a part of the outer peripheral portion of the packaged product 11. The heat seal part 13 has a first opening 14 and a second opening 15 in the middle part of the seal width. The first opening 14 extends from the first opening 14 to the second opening 15 when the heat seal part 13 is torn, but is substantially in the non-heat seal part 17 in which the packaging object is stored. The first tearing portion 16 is formed, which does not reach. The second opening 15 forms a second tear portion 18 that extends from the second opening 15 to the non-heat seal portion 17 when the heat seal portion 13 is torn.

  Although it does not specifically limit as a shape of the packaged goods 11, A substantially circular shape, a substantially triangular shape, a substantially rectangular shape, another polygon, etc. are mentioned. From the viewpoint of storing the packaged items in a space-efficient manner without generating an excessive packaging film, a substantially rectangular shape is preferable.

  The article to be packaged is not particularly limited as long as it is an object to be packaged, but pharmaceuticals, cosmetics, and the like are preferable from the viewpoint of prevention of erroneous opening by an infant or the like. In addition, the infant mentioned in this specification mainly means a preschooler.

  The packaging film 12 is not particularly limited as long as it can be heat-sealed, and is a resin film such as polyethylene, polypropylene, polyester, etc., an aluminum-deposited film if desired, a laminate of these, and an aluminum laminate. And the like.

  The method of hermetic packaging for forming the heat seal portion 13 is not particularly limited, and examples thereof include known methods such as a three-side seal method, a four-side seal method, and a pillow package method. From the viewpoint of ensuring that the packaging film 12 is reliably heat-sealed in an easy manufacturing process and that sealed packaging of the packaged product is ensured, a four-side seal type is preferred.

Both the first opening 14 and the second opening 15 need to be provided at an intermediate portion of the seal width of the heat seal portion 13. When any one of these is provided on the outer edge of the heat seal portion 13, an infant or the like tears the heat seal portion 13 from such an opening, and the generated tear portion reaches the non-heat seal portion 17 so that the infant or the like However, it is not possible to prevent the package 11 from being easily opened. If any of these is provided at the boundary between the heat seal part 13 and the non-heat seal part 17, there is a possibility that the sealing performance of the package cannot be ensured. Therefore, it is preferable that the first opening 14 and the second opening 15 are each provided near the midpoint of the seal width. Specifically, although it depends on the size of the opening, the portion closest to the outer edge of the heat seal portion 13 in the shape of the opening is preferably 1 mm or more, more preferably 2 mm or more from the outer edge. is seperated. Similarly, the portion of these openings closest to the boundary between the heat seal portion 13 and the non-heat seal portion 17 is preferably 1 mm or more, more preferably 2 mm or more away from the boundary.
The first opening 14 needs to form a first tearing portion 16 that extends from the first opening 14 to the second opening 15 when the heat seal portion 13 is torn. In the present specification, both the case where such a first tearing portion ends at the second opening and the case where the first tearing portion extends beyond the second opening are referred to as “extends”.

  Furthermore, the first opening 14 may form a first tear portion 16 that does not substantially reach the non-heat seal portion 17 in which the packaged item is stored when the heat seal portion 13 is torn. is necessary. When a person who wants to open the package 11 tears the heat seal portion 13 from the first opening 14 having a certain shape, a first tear portion 16 is formed in the heat seal portion 13. Since the heat seal part 13 is formed by overlapping packaging films, it is possible to form a tear part in any direction when a strong adult intentionally tears it in a specific direction. Will. However, if the person who intends to open the package 11 does not intentionally create a tearing portion, the first tearing portion 16 is generated in a substantially specific direction depending on the shape of the first opening 14. . Depending on the shape of the first opening 14, a plurality of first tear portions may be generated. For example, as will be described later with reference to FIG. 5, when the first opening 14 is a substantially V-shaped break of the heat seal portion 13, two tears can be generated. In the present specification, all of these are referred to as “first tear portions”, and when none of these reaches the non-heat-sealed portion 17 in which the article to be packaged is stored, this is referred to as “ It's not practical. "

  If the first tear portion 16 directly reaches the non-heat seal portion 17, it is not possible to prevent an infant or the like from opening the package 11 easily.

  The shape of the first opening 16 is not particularly limited as long as the first tearing portion 16 can be formed, and various shapes such as a substantially V shape, a substantially U shape, a substantially I shape, and a substantially X shape in the packaging film. Examples include cuts and punched holes of various shapes such as a substantially triangular shape, a substantially rectangular shape, and a substantially water drop shape.

  From the viewpoint of efficiently forming the first tearing portion 16 that extends from the first opening 14 to the second opening 15, the shape of the first tearing opening 14 is such that the first tearing portion 16 is the second opening. It is preferred that it be oriented towards 15.

  The preferable specific example of the shape of such a 1st opening 15 is shown in FIGS.

  2, which includes a substantially I-shaped cut 22 and a substantially circular punching hole 23 formed in the heat seal portion 21, and a substantially V-shaped 32 cut formed in the heat seal portion 31 illustrated in FIG. 3. 4 formed with a substantially circular punching hole 33 at both ends thereof, formed with a substantially water-drop shaped punching hole 42 formed in the heat seal portion 41 shown in FIG. 4, and formed in the heat seal portion 51 shown in FIG. 6 consisting of a substantially V-shaped cut 52, shown in FIG. 6, consisting of a substantially V-shaped cut 62 formed in the heat seal part 61, and substantially X formed in the heat seal part 71 shown in FIG. 7. For example, it is formed of a character-shaped cut 72.

  As a typical example, the case of FIG. 2 will be described in detail. A person who wants to open the package holds one of the heat seal portions 21 on both sides of the substantially I-shaped cut 22 with one hand and the other with the other hand. And try to tear the heat seal. In this case, the substantially circular punching hole 23 inhibits the heat seal portion 21 from being torn by the expansion of the substantially I-shaped cut 22, so that the tearing portion has a substantially I-shaped shape opposite to the substantially circular punching hole 23. The cut line 22 is generated to extend (in the case of this figure, it is generated along a broken line). As a result, the tear is directed in a substantially constant direction. A second opening is located in this direction. In addition, as long as the heat seal portion 21 is prevented from being torn, a punching hole of an arbitrary shape such as a polygon having only an obtuse angle can be used instead of the substantially circular punching hole 23. It is. Moreover, a too large punching hole is not preferable so that an infant may insert a tool such as a pencil into the punching hole to prevent erroneous opening.

  Similarly, in the case of FIGS. 3 to 7, the tearing portions are generated along the broken lines.

  In order for the first tearing portion 16 to reach the second tearing portion 15 reliably, the packaging film 12 itself has a property of being easily torn along a straight line connecting the first opening 14 and the second opening 15. It is preferable. As such means, a uniaxially stretched film may be employed as the packaging film 12.

  With the configuration of the first opening as described above, even if an infant or the like casually uses a tool such as a pencil, it is difficult to open easily, and an adult goes through the second opening described below. Therefore, it can be opened relatively easily.

  Refer to FIG. 1 again. The second opening 15 forms a second tearing portion 18 that extends from the second opening 15 to the non-heat-sealing portion 17 in which the article to be packaged is accommodated when the heat sealing portion 13 is torn. It is necessary.

  The shape of the second opening 15 can be independently selected from the same shapes as those described above for the first opening 14.

  From the viewpoint of efficiently forming the second tearing portion 18 extending from the second opening 15 to the non-heat seal portion 17, the shape of the second opening 15 is directed toward the non-heat seal portion 17. It is preferable.

  From the viewpoint of efficiently preventing an infant or the like from opening the package 11 directly from the second opening 15, the second opening 15 may not be more conspicuous than the first opening 14. preferable. Since the second opening 15 is less conspicuous than the first opening 14 for those who want to open the package 11, the shape of the second opening 15 consists only of a break in the heat seal portion 13. Is preferred. The shape with a punched hole as shown in FIGS. 2 to 4 is not preferable because it may not be able to efficiently prevent an infant or the like from trying to open it by inserting a pencil or the like there. Examples of the shape of the cut include a substantially I shape, a substantially V shape, a substantially U shape, and a substantially X shape as in the case of the first opening 14.

  More preferably, the person who intends to open the package 11 is prevented from opening from the second opening 15, and from the viewpoint of making it easier to understand that the opening operation is started from the first opening 14, the first opening The mouth 14 can be made more conspicuous than the second opening 15.

  Examples of such means include making the size of the first opening 14 larger than that of the second opening 15. The size of the opening as used herein means the longest length of the shape of the opening. Such sizes are specifically indicated by the lengths of arrows 24, 34, 43, 53, 63 and 73 in the case of FIGS. 2, 3, 4, 5, 6, and 7, respectively. It is.

  Specifically, the size of the first opening 14 and the size of the second opening 14 are preferably 3 to 10 mm and 1 to 3 mm, more preferably 3 to 6 mm and 1 to 2 mm, respectively.

  Further, from the viewpoint of making the first opening opening more conspicuous, the shape of the first opening opening 14 is preferably a shape with a punched hole. These are illustrated in FIGS. 2, 3 and 4.

  In addition, the first opening 14 can be colored, or a message to that effect can be displayed on the packaging film 12 or a container or instruction of a commercial product that packs the package 11.

  FIGS. 8A to F are plan views of the packaged product of the second embodiment of the present invention (including perspective views in a part of FIGS. 8D and 8E), and these show the opening procedure.

  Referring to FIG. 8A, the package 81 has a substantially rectangular shape. The packaging film 82 has a heat seal portion 83 on the entire outer periphery of the packaged product 81. The heat seal portion 83 has a first opening 84 in the vicinity of one vertex of the rectangle of the packaged product 81 and in the approximate center of the seal width. The first opening 84 includes a substantially V-shaped cut and a substantially circular punched hole.

  The second opening 85 includes a substantially V-shaped cut. The second opening 85 is on a straight line that bisects the approximately V-shaped apex angle of the first opening 84, and the straight line that bisects the approximately V-shaped apex angle of the second opening 85 is the non-heat seal portion 86. It is provided in the position which extends to. The first opening 84 is larger than the second opening 85, so that a person trying to open the package 81 can easily start the opening operation from the first opening 84.

  A person who wants to open the package 81 lifts the substantially V-shaped top portion of the first opening 84 with a finger or the like as shown in FIG. In FIG. 8C, the person who is trying to open the package recognizes that the V-shaped top should be opened, and the heat seal portion 83 near one side of the substantially V-shaped with one hand, The heat seal portion 83 in the vicinity of the other side is held with the other hand, and the heat seal portion 83 is torn along the broken line shown in FIG. 8C to form the first tear portion 87 shown in FIG. 8D. In the case of FIG. 8D, the first tear portion 87 extends beyond the second opening 85 to the outer peripheral portion of the package, but the first tear portion 87 reaches the second opening 85. If it does.

  Next, a person who wants to open the package 81 tears the heat seal portion 83 from the second opening 85 along the broken line shown in FIG. 8E and opens the second tear portion 88 extending to the non-heat seal portion 86. Form. As a result, as shown in FIG. 8F, a packaged item 89 appears from the second tearing portion 88 and can be taken out.
