Description

  The present invention relates to a container.

  As a container, a container having a bottomed cylindrical container body having self-supporting properties and a lid that covers the container body so as to cover the opening (hereinafter sometimes referred to as a body container) is generally known. It has been. The body container has advantages that it is easy to take out the contents, that the shape of the container body is maintained regardless of the contents, and that the container is not easily deformed even when the lid body is repeatedly opened and closed.

The body container is used as a container for various articles such as a liquid impregnated material (for example, a decorative sheet) and a mixture of a solid and a liquid (for example, pickles). When the liquid impregnated material or liquid is used as the contents, it is necessary to improve the sealing property between the lid and the container body. However, in order to pursue sealing, the lid becomes harder to open as the fitting force between the lid and the container body is increased.
In order to solve such a problem, there has been proposed a container in which the flange shape of the lid body and the container body is devised in the container in which the flange of the lid body and the flange of the container body are fitted (for example, Patent Documents 1 and 2).

(container)
A container according to an embodiment of the present invention will be described below with reference to the drawings.
The container 1 in FIG. 1 includes a container body 10 and a lid 30.
The container main body 10 includes a rectangular bottom wall portion 14 having one side as a long side in a bottom view and a side wall portion 16 erected from the periphery of the bottom wall portion 14 and has an opening 12 having a rectangular shape in plan view at the upper end. . That is, the container main body 10 has a bottomed rectangular tube shape. As the side wall portion 16 moves away from the bottom wall portion 14, the planar view area increases.
In this paper, a rectangle is a concept that includes one in which a straight line or curved corner is formed at the corner, and one in which all or part of each side is formed by a curve.
A first fitting portion 18 is formed on the periphery of the opening 12, and a first knob 20 having a rectangular shape in plan view is formed near the upper end of the container body 10.

2 is a plan view of the container body 10, and FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1. For convenience of explanation, the container body 10 and the lid 30 are illustrated closer to each other than FIG. Yes.
As shown in FIGS. 1 to 3, an overhang portion 17 is formed on the upper end of the side wall portion 16 so as to project outward in plan view. The overhanging portion 17 goes around the opening 12. The first fitting portion 18 includes a wall portion 18a extending upward from the protruding end of the overhang portion 17, a wall portion 18b extending outward in plan view, and a wall portion 18c extending downward. . That is, the first fitting portion 18 is a ridge formed so as to be erected from the peripheral edge of the overhang portion 17 and then folded.
The wall 18a is inclined inward in plan view of the container body 10 as it goes upward. Since the wall portion 18a is inclined inward of the container body 10, the first fitting portion 18 and the second fitting portion 38 can be fitted more strongly.
Near the upper end of the container body 10, a first knob 20 having a rectangular shape in plan view is formed.
As shown in FIG. 2, the first knob 20 is located at the center of the side 21 that forms one longitudinal side of the rectangular shape in the plan view of the container body 10, and outward from the first fitting portion 18 in the plan view. It protrudes.
The first knob 20 is formed so as to protrude outward in plan view from the folded tip (ie, lower end) of the first fitting portion 18.
On both sides of the first knob part 20, a main body extension part 22 extending from the first knob part 20 and extending along the lower end of the first fitting part 18 is formed. The main body extending portion 22 is formed so as to protrude outward from the first fitting portion 18 in plan view, and circulates around the opening portion 12. That is, the main body extending portion 22 extends from the first knob portion 20, extends along the side 21 that forms the polygon in plan view, and extends to the corner portion 26 and the corner portion 28 that are the end portions of the side 21. Has reached.

The lid 30 closes the opening 12 of the container body 10 so as to be openable and closable. The lid body 30 has a rectangular shape with one side as a longitudinal direction in plan view, and a second fitting portion 38 is formed along the periphery. As shown in FIG. 3, the lid 30 is formed with a stepped portion 36 that descends toward the outside of the lid 30 and then extends outward. The second fitting portion 38 includes a wall portion 38a extending upward, a wall portion 38b extending outward in plan view, and then a wall portion 38c extending downward, following the step portion 36. When 30 closes the opening part 12, it is set as the groove which receives the 1st fitting part 18. As shown in FIG. That is, when the lid 30 closes the opening 12, the first fitting portion 18 and the second fitting portion 38 are fitted, and the container 1 is sealed.
The wall 38a is inclined inwardly in a plan view of the lid 30 as it goes upward. Since the wall portion 38a is inclined inward of the lid body 30, the first fitting portion 18 and the second fitting portion 38 can be fitted more strongly.
Two lids 40 having a rectangular shape in plan view are formed on the lid 30. The second knob 40 is located on both sides in the length direction of the first knob 20 in a plan view when the opening 12 is closed with the lid 30, and a part of the first knob 20 And overlap. That is, the second knob 40 is formed so as to protrude from the same side 21 as the first knob 20 with the lid 30 closed.
On both sides of the second knob 40, a lid extension part 42 extending from the second knob 40 and extending along the lower end of the second fitting part 38 is formed. The lid extension part 42 is formed so as to project outward from the second fitting part 38 in plan view, and circulates around the lid 30. That is, the lid extension part 42 extends from the second knob 40, extends along the side 21, and reaches both corners that are the ends of the side 21.

The material of the container body 10 is not particularly limited. For example, polyethylene, polypropylene, ethylene vinyl acetate copolymer, polyethylene terephthalate, polyvinyl chloride, acrylic resin, polystyrene, acrylic-styrene copolymer, acrylic-butadiene-styrene copolymer, ethylene-vinyl. Examples thereof include alcohol copolymers and composite resins thereof, metal foils such as aluminum foil, and laminates thereof.
The container body 10 may be transparent or colored.
The material of the lid 30 is the same as the material of the container body 10. The material of the lid 30 may be the same as or different from the material of the container body 10.
The container body 10 and the lid body 30 are preferably made of materials having different hardnesses. For example, when the container body 10 and the lid body 30 are made of resin, it is preferable that the resin constituting the container body 10 and the resin constituting the lid body 30 have different bending elastic moduli. Since the container body 10 and the lid body 30 are different in hardness, the container body 10 and the lid body 30 are more closely adhered to each other, and the hermeticity of the container 1 can be further enhanced.

The size of the container body 10 is appropriately determined in consideration of the size and amount of contents. The size of the lid 30 is appropriately determined according to the size of the container body 10.
The thickness of the container body 10 is determined in consideration of the material and the like, and is preferably 0.05 to 2.0 mm, and more preferably 0.1 to 0.8 mm, for example. If it is less than the said lower limit, there exists a possibility that the intensity | strength of the container main body 10 may fall, or the 1st knob | pick part 20 may become too soft and it may become difficult to open. If the value exceeds the upper limit, it is difficult to fit the first fitting portion 18 and the second fitting portion 38 or the first fitting portion 20 is pulled down when the first knob 20 is pulled down in the method of use described later. There is a possibility that the joint portion 18 is difficult to deform.
The thickness of the lid 30 is the same as the thickness of the container body 10.

The length L1 of the first knob 20 is determined in consideration of the size of the container body 10, the material of the container body 10, and the like, for example, preferably 25 to 85 mm, and more preferably 45 to 65 mm. If it is less than the lower limit, the first knob 20 may become too soft and difficult to open, and if it exceeds the upper limit, the area overlapping the second knob 40 will increase, and the first and second There is a risk that it will be difficult to grip the knob.
The width W1 of the first knob 20 is determined in consideration of the size of the container body 10 and the material of the container body 10, and is preferably 10 to 30 mm, and more preferably 12 to 24 mm, for example. If it is less than the said lower limit, it may become difficult to hold | grip the 1st knob | pick part 20 and to open easily. If the value exceeds the upper limit, the first knob 20 may be too soft and difficult to open.
The length of the second knob 40 is appropriately determined in consideration of the size of the lid 30 and the length of the first knob 20. The width of the second knob 40 is the same as the width W1 of the first knob 20.

The width W2 of the main body extension 22 is determined in consideration of the material, thickness, and the like of the container main body 10, and is preferably 1.0 to 8.0 mm, and more preferably 1.5 to 4.0 mm, for example. If it is less than the lower limit, the effect of forming the main body extending portion 22 is difficult to obtain, and if it exceeds the upper limit, the area of the container main body 10 in plan view becomes too large, and the usability may be reduced.
The width of the lid extension part 42 is not particularly limited, and is appropriately determined within the same range as the width W2 of the main body extension part 22.

  The container main body 10 is manufactured by a conventionally known manufacturing method such as injection molding, vacuum molding, or vacuum / pressure forming. The manufacturing method of the lid 30 is the same as the manufacturing method of the container body 10.

(how to use)
Next, the usage method of the container 1 is demonstrated.
The contents are put into the container body 10, the opening is closed with the lid 30, and the container 1 is sealed. The content is not particularly limited, but a wet tissue, a sweat wipe sheet, a sunscreen sheet, an insect repellent sheet, a lotion sheet, a makeup remover sheet, a liquid impregnated sheet in which a liquid such as alcohol or a drug is impregnated into a nonwoven fabric, etc. And sheet products such as wiping sheets that are not impregnated with liquid, such as cooking sheets, tissue papers, and cleaning sheets.
When the opening 12 is closed with the lid 30, the first fitting portion 18 is fitted into the second fitting portion 38, so that the container 1 has a high sealing property.

When taking out the contents, the first knob 20 is held with one hand, and the second knob 40 is held with the other hand. Next, the second knob 40 is pulled up while lowering the first knob 20. If it operates so that the 1st knob | pick part 20 may be pulled down, the 1st fitting part 18 will deform | transform. When the first fitting portion 18 is deformed inside the concave second fitting portion 38, a gap is generated between the first fitting portion 18 and the second fitting portion 38, and the first fitting is performed. The fitting state between the joint portion 18 and the second fitting portion 38 is easily released. In general, the fitting force increases at the corners 26 and 28. According to the container of the present embodiment, since the main body extension 22 extending from the first knob 20 reaches the corners 26 and 28, the force that lowers the first knob 20 causes the main body extension. It is transmitted to the first fitting part 18 through the installation part 22. And the 1st fitting part 18 deform | transforms from the corner | angular part 26 to the corner | angular part 28, and the fitting state of the 1st fitting part 18 and the 2nd fitting part 38 can be cancelled | released easily. The lid 30 can be removed from the container body 10 by further lifting the second knob 40 while releasing the fitted state between the first fitting part 18 and the second fitting part 38.
In addition, the first knob 20 and the second knob 40 are partially overlapped with each other with the lid 30 closing the opening 12, that is, the first knob 20 and the second knob 40 are overlapped. Since the knob 40 is close, the action of pulling down the first knob 20 and the action of pulling up the second knob 40 occur in the same region. And the fitting state with the 2nd fitting part 38 can be cancelled | released more easily.
Furthermore, since the lid body 30 is formed with a lid body extending portion 42 that extends from the second knob 40, the second knob 40 is lifted to extend from the corner 26 to the corner 28. The groove width of the second fitting portion 38 can be widened. For this reason, the fitting state of the 1st fitting part 18 and the 2nd fitting part 38 can be cancelled | released more easily.

As described above, according to the present embodiment, since the first fitting portion 18 and the second fitting portion 38 are formed, when the opening 12 is closed with the lid 30, the container 1 Sealing can be improved.
In addition, since the main body extending portion 22 is formed in the container main body 10, the first fitting portion 18 and the second fitting portion 18 are pulled up by pulling up the second knob 40 while lowering the first knob 20. The fitting state with the fitting part 38 can be released more easily. For this reason, the container 1 can be opened easily.

  As described above, the container 1 of the present embodiment can be easily opened even if the hermeticity is improved. For this reason, the container 1 of this embodiment is suitable as a container for an article accompanied with a liquid, such as a liquid, an article impregnated with the liquid, or a mixture of liquid and solid.
