DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[0021]
FIG. 1 is a perspective view showing a configuration example of a sealed container 10 as a packaging container according to the present embodiment, and FIG. 2 shows a schematic structure of a main part of the sealed container 10 in FIG. 1 as contents (for example, bathing agent, powder detergent). , Instant coffee, powder such as powdered juice, granules, granules, etc.) 5.
[0022]
1 and 2, the sealed container 10 includes a side wall 12, a bottom wall 22, and a lid sheet 32.
[0023]
The side wall 12 has a flat shape with a cross-sectional shape orthogonal to the length direction of the cylindrical body, and has a top opening 16 and a bottom opening 18.
[0024]
Here, the side wall 12 has a flat shape. In particular, in the present embodiment, the four corners of the long rectangular shape are rounded, and the straight portions of the short sides of the rectangle are rounded into a curved shape.
[0025]
The bottom wall 22 is bonded to the side wall 12 along the bottom opening 18 so as to hermetically seal the bottom opening 18, thereby forming the container body 14 in cooperation with the side wall 12.
[0026]
The lid sheet 32 is adhered to the side wall 12 along the top opening 16 so as to hermetically seal the top opening 16.
[0027]
Here, the lid sheet 32 is preferably a single sheet having a thickness of 30 to 500 μm.
[0028]
If necessary, the upper peripheral edge portion of the side wall 12 along the top opening 16 is folded outward to form a flange portion 34, and the lid sheet 32 is bonded to the flange portion 34.
[0029]
Further, the peripheral edge portion 36 of the lid sheet 32 is bonded to the upper peripheral edge portion of the side wall 12 forming the flange portion 34.
[0030]
The flange portion 34 can also be formed using a plate material different from the side wall 12.
[0031]
The lid sheet 32 includes a resin layer made of a uniaxial or biaxially stretched sheet of PET, which is oriented so as to be preferentially cut along a specific direction to be described later.
[0032]
The lid sheet 32 is integrally provided with a tab portion (knob) 38, and a notch 39 is formed at the base thereof.
[0033]
The notch 39 is formed at the peripheral edge portion 36 of the lid sheet 32.
[0034]
As described above, the uppermost PET layer of the lid sheet 32 is a stretched sheet. Therefore, when the tab portion 38 is pulled, the PET is preferentially cut along a planned cutting line as indicated by a one-dot chain line L1 with the notch 39 as a starting end.
[0035]
At this time, other layers are also destroyed together with the uppermost layer PET, and the lid sheet 32 is linearly cut along the planned cutting line L1.
[0036]
Thereby, an opening having a certain width corresponding to a part of the top opening 16 can be formed in the lid sheet 32.
[0037]
The planned cutting line L1 of the lid sheet 32 is a lid at a position corresponding to a portion where the width of the cylindrical body formed by the side wall 12 starts to narrow, or between this portion and the adjacent end on the long axis side of the cylindrical body. It arrange | positions so that the sheet | seat 32 may be crossed.
[0038]
For this reason, the notch 39 at the base of the tab portion 38 is formed in the lid sheet 32 at a position that is the starting point of the planned cutting line L1.
[0039]
For example, in the case of the sealed container 10 having the above dimensions, the distance along the long axis between the adjacent end on the long axis side and the notch 39 is set to 2 mm to 30 mm.
[0040]
Thereby, desirable effects can be obtained from the viewpoint of protecting the contents after opening the container, easiness of taking out the contents, or preventing the contents from remaining.
[0041]
The container main body 14 may be made of paper, metal, plastic, or a combination thereof, and is preferably made of paper in consideration of usability (particularly ease of holding).
[0042]
Below, the preferable specific example in case the container main body 14 is paper is demonstrated.
[0043]
The side wall 12 preferably has a thickness of 0.3 to 3 mm, and a rectangular one having a length substantially corresponding to the circumferential length of the cylinder formed by the side wall 12, that is, the circumferential length of the container body 14. It consists of a single plate.
[0044]
The plates constituting the side wall 12 are rounded in the length direction so that the container body 14 has a flat shape, that is, there are no corners along the circumferential direction of the container body 14, and the side ends thereof are overlapped. Bonded together.
[0045]
FIG. 3 is a cross-sectional view showing an example of a mode of superimposing both side end portions of the side wall 12.
[0046]
In FIG. 3, the side wall 12 (that is, the plate constituting the side wall 12) is made of a moisture-proof material mainly composed of paper and has a laminated structure including a front label 42, an intermediate layer 44, and an innermost layer 46. These layers also have a laminated structure.
[0047]
First, the front label 42 has a moisture-proof laminated structure of back-printed PET (polyethylene terephthalate film) and paper, and the paper is arranged on the side in contact with the intermediate layer 44.
[0048]
The intermediate layer 44 is made of paper and has either a single-layer structure of base paper or a structure in which a plurality of layers of base paper are bonded together with an adhesive.
[0049]
The innermost layer 46 has a laminated structure in which at least paper, PET, and a sealant are stacked and has moisture resistance and aroma retention, and the paper is disposed on the side in contact with the intermediate layer 44.
[0050]
Here, the sealant may be any resin that can be thermally bonded, and is selected from, for example, polyethylene, ethylene vinyl acetate copolymer, ethylene acrylic acid copolymer, and ionomer resin.
[0051]
As shown in FIG. 3, in the mode of superimposing both side end portions of the side wall 12, one end portion 42 a of both side end portions 42 a and 42 b of the front label 42 is peeled off from the intermediate layer 44, It adheres on the end 42b.
[0052]
The both side end portions 44a and 44b of the intermediate layer 44 are cut obliquely, overlapped with each other, and bonded via an adhesive.
[0053]
Thereby, the thickness of the side wall 12 does not increase due to the overlap of the intermediate layer 44.
[0054]
In addition, of the both side end portions 46a and 46b of the innermost layer 46, the end portion 46b facing the inside of the sealed container 10 is folded back to the intermediate layer 44 side and bonded to the other end portion 46a. Yes (edge protection structure).
[0055]
Thereby, it becomes possible to ensure the predetermined moisture permeability and aroma retention property of the sealed container 10.
[0056]
On the other hand, the bottom wall 22 is preferably made of a single plate having a thickness of 0.2 to 1 mm.
[0057]
The peripheral edge of the bottom wall 22 has a shallow oval cylindrical shape having legs 24 formed by folding downward, and is fitted to the bottom opening 18 side of the cylinder formed by the side wall 12.
[0058]
The lower peripheral edge portion of the side wall 12 along the bottom opening 18 is folded inward so as to wrap the leg portion 24 of the bottom wall 22 to form a bottom folded portion 26.
[0059]
The leg portion 24 of the bottom wall 22 is bonded to the bottom folded portion 26 on both the inside and outside.
[0060]
Thereby, it becomes possible to ensure the predetermined moisture permeability of the sealed container 10.
[0061]
The bottom wall 22 (that is, a plate constituting the bottom wall 22) is made of a moisture-proof laminated material having paper and PET as a central layer and heat-sealable resin layers disposed on both sides.
[0062]
The heat-sealable resin layer disposed on the inner surface side of the container is desirably the same as the resin that forms the inner surface of the side wall 12.
[0063]
The sealed container 10 further includes a cap 42 that fits into the flange portion 34 of the side wall 12 so as to cover the top opening 16.
[0064]
The cap 42 is used to seal the opening of the lid sheet 32 after the lid sheet 32 is cut and the sealed container 10 is opened.
[0065]
Further, the cap 42 can be formed to have a function as a measuring cup for measuring the amount of contents.
[0066]
Further, the cap 42 is formed with protrusions (claw portions) 40 for preventing slippage, which are fitted on the outer wall surface of the bottom folded portion 26 of the container body 14 at four rounded portions along the circumferential direction on the outer surface thereof. is doing.
[0067]
Thereby, it becomes possible to prevent the shift | offset | difference at the time of stacking the sealed container 10. As shown in FIG.
[0068]
Next, in the sealed container 10 of the present embodiment, the side wall 12 of the container main body 14 has a flat cross-sectional shape perpendicular to the longitudinal direction of the cylindrical body. It is assumed that the following conditions are satisfied.
[0069]
FIG. 4 is a conceptual diagram illustrating an example of a cross-sectional shape orthogonal to the length direction of the side wall 12.
[0070]
That is, as shown in FIG. 4, the dimension R1 of the first axis that passes through the substantially center of the container body 14 and connects the two opposite side surfaces of the flat shape is 50 mm to 85 mm, preferably 60 mm to 70 mm. In addition, the dimension R2 of the second axis that passes through substantially the center of the container body 14 and connects the other two opposite side surfaces of the flat shape and is orthogonal to the first axis is 90 mm to 120 mm, preferably 100 mm to 110 mm. In addition, all these side surfaces have a structure that is continuous through curved surfaces.
[0071]
Here, the dimensions R1 and R2 of the respective shafts are about 15 cm to 20 cm in average of the size of the user's hand of the sealed container 10, that is, the length from the tip of the thumb to the tip of the middle finger through the palm. Therefore, it is decided based on this.
[0072]
In addition, the height dimension of the container main body 14 of the sealed container 10 is 8 cm to 20 cm, preferably 10 cm to 18 cm, and more preferably 15 cm.
[0073]
As a result, the size of the user's hand of the sealed container 10, that is, the average length from the tip of the thumb to the tip of the middle finger through the palm is approximately 15 cm to 20 cm. When holding and swinging out the contents 5 and using the sealed container 10 with one hand, the thumb position of the hand is located at about half of the second axial direction. The palm fits into the side wall 12 of the sealed container 10 to make it easier to hold the container. Especially when the palm is slightly wet, for example, the sealed container 10 is not slipped and dropped from the hand. The container 10 can be held with peace of mind, and the contents 5 can be easily shaken out.
[0074]
Furthermore, the cross-sectional shape of the container body 14 of the sealed container 10 is a flat shape, so that when the plurality of sealed containers 10 are stored and stored, the conventional cross-sectional shape described above is circular. Since the dead space is reduced as compared with the case, the sealed container 10 can be easily stored and stored, and the efficiency can be improved.
[0075]
FIG. 5 thru | or FIG. 9 is a figure which shows an example of the result of having investigated 125 persons inside (survey period 1 month) regarding the sealed container 10 of this Embodiment.
[0076]
FIGS. 5 and 6 show the results of the survey on the ease of holding the sealed container 10, FIG. 7 shows the ease of storage and storage of the sealed container 10, and FIGS. Each is shown.
[0077]
As apparent from FIGS. 5 to 9, the shape of the cross section perpendicular to the length direction of the container body 14 forms a flat shape, passes through substantially the center of the container body 14, and one of two opposing side surfaces. The dimension R1 of the first axis connecting the two is 50 mm to 85 mm, passing through the substantial center of the container body 14, connecting the other two side surfaces facing each other, and the dimension of the second axis orthogonal to the first axis By making the sealed container 10 having a structure in which R2 is 90 mm to 120 mm and all side surfaces are continuous through curved surfaces, the ease of holding the sealed container and the storage and storage of the sealed container are improved. It can be seen that superior effects can be obtained compared to the case of the conventional sealed container in all points of ease of operation and ease of dispensing the contents of the sealed container.
[0078]
As described above, the sealed container 10 of the present embodiment is excellent in appearance, usability, and mechanical strength, and can reduce problems from the viewpoint of storing and taking out the contents 5.
[0079]
On the other hand, when the container 5 is gripped by hand and the contents 5 are shaken out and used, when the container is gripped with one hand, the position of the thumb of the hand is located at about a half of the second axial direction. Therefore, the palm fits to the side wall 12 portion of the sealed container 10 so that the container can be easily held, the container can be held with peace of mind, and the contents 5 can be easily swung out.
[0080]
Furthermore, when storing and storing a plurality of containers, since the dead space is smaller than when the cross-sectional shape is circular, it is easy to store and store the containers and improve efficiency. .
[0081]
Furthermore, since the protrusion (claw part) 40 for preventing slippage that fits into the bottom of the container main body 14 is formed on the outer surface of the cap 42, it is possible to prevent slippage when the sealed containers 10 are stacked. Is possible.
[0082]
