A container includes a cylindrical container body having an open upper end and a closed lower end, and a lid 1 having a substantially inverted U-shaped vertical cross section, which is detachably attached to the upper end of the container body.
The lid 1 is forcibly fitted from below into the short cylindrical body 15 provided with the inward flange 2 over the entire circumference at the upper end, and the peripheral portion is closely attached to the inward flange 2 and adhered. The top plate 3 is formed. The inward flange 2 of the short cylindrical body 15 is inclined upward toward the inside. The top plate 3 is connected to the inner peripheral edge of the annular peripheral edge portion 3a and the annular peripheral edge portion 3a that is inclined upward inward and is closely adhered to the lower surface of the inward flange 2 and is bonded to the inner peripheral edge of the annular peripheral edge portion 3a. It comprises a rising portion 3b with which the tip of the second member abuts, and a central upper bulging portion 3c which is continuous with the upper end of the rising portion 3b and bulges like a dome toward the center.

[Technical field to which the device belongs]

 The present invention relates to a container for sticks such as stick-shaped chocolate, somen, and spaghetti, green tea and black tea leaves, coffee beans, snacks and the like.

[Prior art]

 Conventionally, a container as described above has a bottomed cylindrical container body (10) having an open upper end and a closed lower end, and an upper end of the container body (10) as shown in FIGS. 3 and 4, for example. It consists of a lid (11) with a vertical cross section that is substantially inverted U-shaped.

The container body (10) includes a long cylindrical body (12) including a cylindrical inner wall (12a) and a cylindrical outer wall (12b) closely attached to the outer peripheral surface thereof, and a long cylindrical body (12). It consists of a bottom plate (13) that closes the bottom opening of the. The upper end of the inner wall (12a) is projected above the upper end of the outer wall (12b). Further, the upper end opening of the inner wall (12a) may be closed with an inner lid or a membrane piece. The lower end of the outer wall (12b) projects below the lower end of the inner wall (12a), and an inward curl (14) having a substantially circular cross section is formed over the entire circumference at the lower end of this protruding portion. The bottom plate (13) has a flat plate shape and is fixed to the long tubular body (12) by forcibly fitting it into the outer wall (12b) from above and by adhering the peripheral edge portion to the inward curl (14) with an adhesive. ing .

The lid (11) is composed of a short cylindrical body (15) and a top plate (16) for closing the upper end opening of the short cylindrical body (15). A horizontal inward flange (17) is integrally formed on the upper end of the peripheral wall of the short cylindrical body (15) over the entire circumference. The inward flange (17) is formed by bending the upper end portion of the short cylindrical body (15) inward in the radial direction and folding the tip end downward and outward in the radial direction. The folded part is indicated by (17a). The top plate (16) has a flat plate shape, and is forcibly fitted into the short cylindrical body (15) from below, and the peripheral edge portion is brought into close contact with the lower surface of the inward flange (17) and bonded with the adhesive (18). As a result, it is fixed to the short cylindrical body (15).

[0005]

[Problems to be solved by the device]

 However, the conventional container has the following problems. That is, when a downward force is applied to the top plate (16) of the lid (11), the top plate (16) is deformed so as to bend downward as shown in FIG. 5, and the above force is applied to the top plate (16). ) And the inward flange (17) are acted downwardly, the inward flange (17) bends downward with the base end as a fulcrum, and the folded portion (17a) opens downward. There has been a problem that the peripheral edge of the top plate (16) easily separates from the inward flange (17).

An object of the present invention is to solve the above problems and to provide a container in which the peripheral portion of the top plate is difficult to separate from the inward flange even when a downward force is applied to the top plate of the lid. It

[0007]

[Means for Solving the Problems]

 The container according to the present invention comprises a tubular container body having an open upper end and a closed lower end, and a lid having a generally U-shaped vertical cross section which is detachably attached to the upper end of the container body. A cylindrical body with an inward flange on the entire circumference, and a container with a top plate that is forcibly fitted into the cylindrical body from below and whose peripheral edge is closely attached to the inward flange. The inward flange of the body is inclined upwards inward, and the top plate is inclined upwards inward and is adhered to the lower surface of the inward flange in close contact with the annular periphery. Section, a rising part that is continuous with the inner peripheral edge of the annular peripheral part and is in contact with the tip of the inward flange, and a central upward bulging part that is continuous with the upper end of the rising part and bulges like a dome toward the center. It will be.

According to this container, when a downward force is applied to the top plate of the lid, this force tries to push the central upper bulging portion of the top plate and spreads it outwardly and obliquely downward, When the rising portion of the top plate hits the tip of the inward flange, the force is received by the tip of the inward flange. Therefore, the adhesive force between the annular edge of the top plate and the inward flange is less likely to be applied with a force to separate them, preventing the top edge of the annular edge from separating from the inward flange. To be done.

[0009]

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to the drawings. In the following description, the same parts and parts as those shown in FIGS. 3 to 5 are designated by the same reference numerals, and the duplicate description will be omitted.

In FIG. 1 and FIG. 2, an inward flange (2) inclined upward inward is integrally formed on the upper end of the short cylindrical body (15) of the lid (1) over the entire circumference. Has been. The inward flange (2) is formed by bending the upper end of the short cylindrical body (15) obliquely inward and upward, and folding its tip downward and outward obliquely downward. The top plate (3) has a substantially hat-shaped vertical cross section, is inclined upward inward, and is formed into an annular peripheral edge portion (3a) closely attached to the lower surface of the inward flange (2) and an annular peripheral edge portion (3a). The rising part (3b) that is connected to the inner peripheral edge of (3a) and is in contact with the tip of the inward flange (2), and the upper part of the center that is connected to the upper end of the rising part (3b) and bulges like a dome toward the center. Consists of a bulge (3c). The annular peripheral portion (3a) is adhered to the lower surface of the inward flange (2) with an adhesive (18). The upper surface of the central upper bulging portion (3c) is flush with the upper surface of the inward flange (2).

In such a configuration, when a downward force is applied to the top plate (3) of the lid (1), this force pushes and expands the central upper bulging portion (3c) of the top plate (3). As shown by the arrow in Fig. 2, the force acts diagonally downward and outward, but the rising part (3b) of the top plate (3) hits the tip of the inward flange (2), and the above force is applied inward. It will be received by the facing flange (2). Therefore, the adhesive force between the annular peripheral edge (3a) of the top plate (3) and the inward flange (2) is less likely to be applied with a force to separate the two, and the circle of the top plate (3) is less likely to be applied. The annular peripheral edge portion (3a) is prevented from peeling from the inward flange (2). Then, as shown by the chain line in FIG. 2, only the central upper bulging portion (3c) of the top plate (3) is deformed downward.

[0012]

[Effect of device]

 According to the container of this invention, as described above, even when a downward force is applied to the top plate of the lid, peeling from the inward flange of the annular peripheral edge of the top plate is prevented.
