Description

[Detailed description of the invention] (Industrial application field) This invention has excellent shape retention, water resistance, oil resistance,
The present invention relates to an easy-to-open, shape-retaining sealed container that has excellent sealing properties such as gas barrier properties and is easy to open.

(Prior art) In recent years, so-called half-baked crepes and half-baked cakes have been produced and packaged in large-scale factories of confectionery companies, etc., put through the distribution process, and sold in large quantities at supermarkets, food stores, etc. . Regarding the packaging of these confectionery products that are placed in the distribution process, these confectionery products are inherently prone to losing their shape even when subjected to even the slightest external force, and are also prone to spoilage, which further increases the desire to purchase. There are a number of points that require special attention, such as the need for beautiful printing on the surface in order to increase sales effectiveness.

Therefore, packaging as illustrated in FIGS. 9A, 9B, and 9C has generally been used.

That is, as shown in FIG. 9A, confectionery M is filled into a tray 100 formed by vacuum forming or the like. Filling is performed by dropping the confectionery M onto the tray 100 moving on a belt conveyor using a filling machine. Next, as shown in FIG. 9B, the confectionery M
The entire tray 100 filled with
0 and seal it. Next, as shown in FIG. 9C, the sealed bag 200 is placed in a paper box 300 whose surface is beautifully printed to complete the packaging.

In this packaging, one confectionery M is first filled into each space partitioned by a partition 110 provided in the tray 100, as shown in FIG. 9A. Therefore, even if the tray 100 is tilted during transportation, the confectionery M will not be misaligned within the tray 100 and the confectionery M will not lose its shape. In addition, side walls 120 around the tray 100
The height of the confectionery M is greater than the height of the confectionery M, and as shown in FIG. This prevents the thiokolate and the like applied to M from adhering to the inner surface of the bag body 200. Furthermore, by making the height of the side wall 120 larger than the height of the confectionery M, as shown in FIG. An external force is applied and the paper box 300
Even if the top plate 310 of the top plate 310 is slightly dented, the top plate 310
This prevents the confectionery M from losing its shape due to impact from the outside.

In addition, in such packaging, generally confectionery M
Confectionery M
The excessive dissipation of moisture and oil from the confectionery M causes a deterioration in the flavor of the confectionery M, which is not desirable. In addition, in such packaging, a portion of the confectionery M is impregnated with alcohol in order to prevent the propagation of bacteria inside the confectionery M, prevent spoilage of the confectionery M, and extend the shelf life of the confectionery M. Alcohol powder may be mixed into M, but it is also necessary to prevent these alcohol components from becoming gas and dissipating. Therefore, in this packaging, the tray 100 filled with confectionery M is
The bag 200 is sealed and housed in a bag 200 that has excellent sealing properties such as water resistance, oil resistance, and gas barrier properties. As the material for the bag body 200, a sheet-like material having a plastic layer with high barrier properties, etc. is used, and a material having a plastic sheet-like material layer coated with aluminum is also used.

In addition, in this packaging, if it is to be sold only after being stored in the bag 200 as shown in FIG. 9B, even if the surface of the temporary bag 200 is printed, the Because printing is done on so-called flexible packaging materials, there are limits to the number of colors, precision, etc., and it is difficult to sufficiently increase the product value. Furthermore, in order to protect the confectionery M from external forces during transportation and to completely prevent it from losing its shape, the tray 100 alone cannot be said to be strong enough. In this case, the tray 100 becomes quite expensive. If the bag body 200 is provided with sufficient water resistance, oil resistance, gas barrier properties, etc., and the tray 100 is provided with sufficient strength, the confectionery M will not be fully visible from the outside. I often get used to it. Therefore, it becomes necessary to print and display the delicious appearance of the stored confectionery M on the surface of the bag body 200, but as mentioned above, there are technical limits to printing on the bag body 200. It is not always easy to fully reproduce the delicious appearance of M. Therefore, in this packaging, the bag body 200 is housed in a paper box 300 made of paper that is highly suitable for printing and has considerable rigidity, thereby increasing the sales effect and the confectionery M that is housed.
Efforts are being made to prevent the product from losing its shape.

(Problems to be solved by the invention) The conventional packaging of half-baked crepes, half-baked cakes, etc. as shown in Figure 9 A, B, and C involves a large number of packaging steps, and the packaging process takes too much time and money. It was hot. In addition, in conventional packaging, confectionery M
It is virtually impossible to package these products individually, which is inconvenient for both manufacturers and sellers as well as consumers.

In other words, the conventional packaging shown in FIG. However, in order to achieve these objectives, Tray 1
00, the bag body 200, and the paper box 300, three types of members are required, and procuring these members requires considerable material costs, manufacturing costs, etc. In addition, the filling and packaging process itself for confectionery M, which is performed using these various parts, is complicated due to the large number of parts used, and requires considerable effort and expense. . Therefore, a considerable amount of effort and expense is required from the procurement of the members to the completion of packaging, and there is a problem in that the packaging as a whole requires too much effort and expense.

In addition, the packaging shown in Figure 9 A, B, and C is for wrapping a large number of confectionery M, such as 8 or 10 pieces, at the same time, and even when such a large number of pieces are packaged at the same time, it takes time and effort to wrap them. From a profit standpoint, it is impossible to package each confectionery M in the packaging shown in Fig. 9 (a), (b), and (c) because the cost and expenses are too high. Therefore, if the packaged item is, for example, 10 pieces, a certain consumer may
If a consumer only wants one item, he or she has to choose between buying 10 items or none at all, which is inconvenient. Also, one bag body 2
For example, 10 sweets M are covered and protected in 00. Therefore, if a consumer opens the bag 200 to eat only one piece, the remaining nine pieces will no longer be protected by the bag 200 having barrier properties. This caused the inconvenience of having to eat the remaining nine pieces in a hurry.

On the other hand, it is difficult for manufacturers and sellers to sell Confectionery M to people who feel inconvenienced as described above. Therefore, there was a problem in that it was difficult to significantly increase the sales of Confectionery M.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides an easy-to-open, shape-retaining sealed container with water resistance, oil resistance, gas barrier properties, etc. on the inside of a rigid paperboard. a substantially cylindrical body having a sheet-like material layer with excellent sealing properties;
A shape-retaining part and a sealing part are provided in order on each extension part from both ends of the body, and the sealing part is formed by pasting the opening edges of the extension part to each other in a narrow strip shape,
The shape-retaining portion includes a triangular side surface surrounded by a substantially isosceles triangular fold whose vertices are the end points of the side sides of the sealing portion, and a curved side surface adjacent to the outside of the bottom of the triangular side surface. and a gently sloped portion extending from between the curved side portions to between the triangular side portions, two cut lines are provided in the paperboard of the body portion, and the body portion between the cut lines is provided. A zipper for opening is formed by pasting a cut tape on the inner surface, and a gripping piece is provided on the outer edge of the zipper for opening.

(Function) In the easy-open shape-retaining sealed container of this invention,
The rigidity of the paperboard, the triangular side part forming a substantially flat plate shape, and the curved side part protruding into a curved surface shape,
In addition, the triangular side portion and the curved surface portion press the gently sloped portion from both sides to maintain the gently sloped shape, thereby firmly retaining the shape of the shape retaining portion.

In addition, the container body is highly sealed due to the presence of the sheet-like material layer with excellent sealing properties such as water resistance, oil resistance, and gas barrier properties, and the bonding of the sealing portion.

In addition, because the body is easy to break along both side edges of the cut tape, and because two cut lines are provided in advance on the paperboard, which is the most difficult to break in the body, the body has two cut lines. It is easily and cleanly broken along the score line.

The folding lines 10 and 11 are the fold lines 10 and 11 that are formed so that when the blank board B is rolled up laterally and the side edges are pasted together to form a cylindrical body, they face each other across the central axis of the cylindrical body. located at the location. A fold line 15 is provided in parallel to the fold line 5 in a portion of the storage section 9 near the intersection 14 between the fold line 5 and the fold line 10. Folding lines 16, 16 are also provided between both ends of this folding line 15 and the intersection point 14, and these folding lines 16, 16 and the folding line 15 form a triangular side surface of a substantially isosceles triangle with the intersection point 14 as the apex. A section 17 is formed into sections. Similarly, a triangular side portion 18 whose apex is the intersection of the fold line 5 and the fold line 11 is defined by the fold line 15 and the fold lines 16, 16, and also between the fold line 6 and the fold lines 12, 14. Triangular side portions 19 and 20 having respective intersection points as vertices are defined by the fold line 15 and the fold lines 16 and 16, respectively. Note that among the above-mentioned folding lines, folding lines 5, 6, and 15 are folding lines for so-called valley folding,
The folding lines 10, 11, 12, 13, and 16 are folding lines for so-called mountain folding. In addition, the storage section 9
There are two horizontally parallel cut lines 2 approximately in the center of the
1 and 22 are provided only on the paperboard 1, and this score line 2
Cut tape 23 is placed on the inner surface of the storage section 9 between 1 and 22.
is attached to form the opening zipper part 24. As shown in FIG. 4, the cut tape 23 is
From the surface side, a polyethylene sheet layer 25,
It consists of three layers: a polyester sheet layer 26 and a polyethylene sheet layer 27, and is heat-sealed to the polyethylene sheet layer 4 of the storage portion 9 by the polyethylene sheet layer 25. Also, the width of this cut tape 23 is the width of the cut line 2.
The width is slightly narrower than that between 1 and 22. As mentioned above, in FIG. 2, the grain of the paperboard 1 is oriented horizontally, so the score lines 21 and 22 are parallel to the grain of the paperboard 1. In addition, the opening zipper part 24
Small notches 28 and 28 connected to the cut lines 21 and 22 are provided near the left end, and a portion between the small notches 28 and 28 is used as a gripping piece 29.

When assembling and using, first, as shown in FIG. The inner surfaces of the right side edges 31 are overlapped, and the left side edges 30 and the right side edges 31 are heat-sealed using the polyethylene sheet layers 4 and 27 to perform so-called body bonding. Next, as shown in FIG. 6, the lower sealing part 8 is folded along the folding lines 6 and the folding lines 12 and 13, and the inner surfaces of the sealing parts 8 are brought into contact with each other, and the polyethylene sheet layer 4 is folded.
Heat seal the inner surfaces together. This closes the lower end. Next, as shown in FIG. 7, when the triangular side parts 19 and 20 are pressed from the outside, the triangular side parts 19 and 20 form the fold lines 12 and 20, respectively.
It becomes approximately flat plate-like above 13, and each triangular side part 1
The upper portions adjacent to 9 and 20 are curved to form curved side portions 32 and 33. At the same time, the area extending from the portion between the triangular side portions 19 and 20 to the portion between the curved side portions 32 and 33 is a gentle slope portion 34,
It becomes 35. These triangular side parts 19, 20,
The curved side portions 32, 33 and the gentle slope portions 34, 35 constitute a shape retaining portion 36 that retains the shape of the vicinity of the lower end of the container body. This shape-retaining portion 36 is formed by including the rigid paperboard 1 in the material and by each triangular side portion 1.
9 and 20 respectively extend the curved side surfaces 32 and 33 adjacent above them into a curved surface shape, and the triangular side surfaces 19 and 20 and the curved side surfaces 32 and 3
3 presses the gently sloped portions 34 and 35 from both sides to maintain the gently sloped shape, thereby firmly retaining the shape of the lower end portion of the container body. When assembled to the state shown in FIG. 7, stored items such as half-baked cakes are dropped from above and stored through the upper opening. Next, after heat-sealing the upper sealing part 7, the triangular side parts 17 and 18 are pressed to form an upper shape-retaining part 37, and the assembly is completed (FIG. 1). Heat sealing of sealing part 7 and triangular side parts 17 and 18
The formation of the shape-retaining portion 37 by pressing is the same as described regarding the lower sealing portion 8 and the lower shape-retaining portion 36. The upper and lower ends of the stored article enter the shape retaining parts 37 and 36, respectively, but the central part of the stored article enters the body part 38 between the shape retaining parts 36 and 37.
This body part 38 has a substantially cylindrical shape, and both upper and lower ends of the body part 38 are firmly retained in shape by shape retaining parts 37 and 36, and the paperboard 38 has rigidity in its material. The shape is strongly retained due to the inclusion of .

To open the package, as shown in FIG. 8, by grasping the gripping piece 29 and pulling the opening zipper part 24, the body part 38 is broken along the cut lines 21 and 22. The opening zipper part 24 is inserted from the body part 38.
can be separated. When the opening zipper part 24 is separated, even if it comes off from the score lines 21 and 22 and is broken, in this embodiment, the paperboard 1 is aligned with the score lines 21 and 22.
Since it is parallel to the cut line 21,
It only partially comes off near 22, and the cut line 2
It does not deviate significantly from 1.22. After removing the zipper part 24 for opening, the upper part of the container body divided into upper and lower parts is removed from the stored article, and then the stored article is taken out from the lower part.

In addition, the delivery of containers from container manufacturers to container users who store confectionery, etc. in the containers for sale uses the round tube delivery method, in which the containers are delivered in a cylindrical body with a body attached, as shown in Figure 5. It may also be tilted, and the second
As shown in the figure, a winding delivery method may be used in which the blank board is delivered in a rolled state before being cut into individual blank boards B.

The present invention is not limited to the above-mentioned embodiments, and the blank board may be made of other materials as long as it has a sheet-like material layer with excellent sealing properties such as water resistance, oil resistance, and gas barrier properties on the inside of the paperboard. The layer structure may be arbitrarily determined. In addition, the sheet material layer with high sealing properties such as water resistance, oil resistance, gas barrier properties, etc. is not limited to aluminum foil, but may also be a plastic sheet material with high barrier properties or a laminate thereof. Alternatively, it may be a sheet of plastic coated with aluminum.

Further, the body adhesion may be performed by adhering the inner surfaces of the left and right side edges to each other.

In addition, by aligning the paper grain of the paperboard with the direction of the cut line of the opening zipper part, the cut line of the opening zipper part can be set more closely than other parts of the paperboard, such as so-called half-cut lines or perforation lines. It may be replaced with one that is easy to break in a certain direction.

Further, the gripping piece may be a piece in which the end of the zipper part for opening protrudes from the side edge of the container body.

Note that the opening zipper portion may be provided anywhere on the body.

Moreover, the crease between the sealing part and the shape-retaining part (storage part) may be omitted.

Furthermore, the stored items are not limited to half-baked crepes and half-baked cakes, but may be anything.

Note that the storage of stored items is not limited to dropping from above, but it is also possible to store the cylindrical item with the body attached horizontally from one side opening end, and the heat seal of the sealing part and the The shape-retaining portion may be formed on both sides at the same time.

(Effects of the invention) The present invention is constructed as described above, and includes a rigid paperboard in the material, and a container body and a body part.
The shape-retaining part is composed of a shape-retaining part and a sealing part, and the shape-retaining part has a triangular side part surrounded by a substantially isosceles triangle-shaped crease whose apex is the end point of the side of the sealing part, and the triangular side face. By providing a curved side surface adjacent to the outside of the bottom of the part and a gentle slope extending from between the curved side surfaces to between the triangular side surfaces, the triangular side surface becomes approximately flat and the curved side surface is stretched into a curved side surface shape, and the triangular side surface portion and the curved side surface portion press the gentle slope portion from both sides to maintain the gentle slope shape,
The shape retention part is strongly retained. The shape of the body is also strongly maintained by the shape-retaining parts at both ends, and the rigid paperboard is included in the material, so that the container body as a whole is Strongly retained. Therefore, even if items that easily lose their shape, such as half-baked crepes or cakes, are stored and transported, the stored items may lose their shape due to external forces received during transportation. There isn't.

In addition, by providing two score lines on the paperboard of the body and pasting cut tape on the inner surface of the body between the score lines to form a zipper part for opening, it is possible to break the paperboard, which is difficult to tear. In addition to being able to open the body part without cutting, the sheet-like material layer, which has excellent sealing properties such as water resistance, oil resistance, and gas barrier properties, can be torn along two score lines. Therefore,
You can easily separate the torso by simply gripping the gripping piece and pulling it.
The container body can be opened by tearing along the cut line of the strip and removing the opening zipper part. Moreover, since the package is easy to open, there is no possibility that the package will lose its shape due to fingers or the like hitting the package when opening the package.

In addition, if the paper grain of the paperboard matches the direction of the cut line, the score line can be made easier to break in a certain direction than other parts of the paperboard, such as a half-cut line or perforation line. In this case, the opening zipper section not only allows the body to be opened easily, but also prevents the break in the body from deviating significantly from the score line.

In addition, by including a sheet-like layer with excellent sealing properties such as water resistance, oil resistance, and gas barrier properties in the material, and by bonding the inner surfaces of the open edges at both ends in a narrow strip shape, the container Highly sealed body. Therefore, stored items are protected and have a long shelf life. for example,
If a part of the half-baked cake is impregnated with alcohol or mixed with alcohol powder to prevent spoilage, the alcohol will gasify over time. Due to its high gas barrier properties, the gasified alcohol remains inside the container. Therefore, half-baked cakes and the like are prevented from spoiling.

Furthermore, by using paperboard as the outer surface, beautiful printing can be applied to the surface, increasing sales effectiveness.

In addition, the structure is extremely simple, and only a single layered sheet material is used, making manufacturing and product packaging easy, and mass production and packaging can be carried out at low cost. Therefore, packaging costs will not increase even if each product is packaged one by one. If each product is packaged individually, it is convenient for consumers to buy as much as they want and consume as much as they want to consume. Therefore, the purchase quantity increases. On the other hand, manufacturers and distributors can increase sales volume.
