Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container hinge.
[0002]
[Prior art]
As a hinge that connects the first container component and the second container component, there is one that is integrally formed with a plastic sheet together with both container components.
[0003]
[Problems to be solved by the invention]
The subject of this invention is making it easy to bend, and suppressing the curvature of the longitudinal line of a hinge, reducing the size of a hinge and improving an external appearance property.
[0004]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a pair of connection portions connected substantially orthogonal to each of the first container component and the second container component, and both substantially orthogonal to both of the connection portions. a joint portion for connecting the connecting portion, and an outwardly convex portion which is formed in the center of the joint portion becomes integrally molded with both containers constituting parts of both connections and joints by plastic sheet, first And a container hinge that seals the mating surfaces of the second container constituent parts and seals them, and an L-shaped root part is provided at a portion where both connecting parts are connected to the first and second container constituent parts. It is intended to be prepared .
[0005]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 and 2, the container 10 is a vacuum molded body or a compressed air molded body of a plastic sheet such as PET, and includes first and second cup-shaped container components 11 and 12 and a hinge 20. It is an integral molding.
[0006]
The hinge 20 is substantially orthogonal to each of the pair of connection parts 21 and 22 connected to the first container component part 11 and the second container component part 12 substantially orthogonally to each of the connection parts 21 and 22. And a connecting portion 23 for connecting the connecting portions 21 and 22, and a rounded (arc-shaped) outward projecting ridge portion 24 formed at the center of the connecting portion 23. Both connecting portions 21 and 22 are provided with L-shaped root portions 21 </ b> A and 22 </ b> A having small cross sections at portions connected to the first and second container constituting portions 11 and 12.
[0007]
As an example of the specific size of the hinge 20, as shown in FIG. 1, a = 7 mm, b = 6 mm, c = 0.5 mm, d = 2.5 mm, e = 0.5 mm, and R = 1 mm.
The container 10 is sealed by overlapping the mating surfaces of the first container component 11 and the second container component 12 by deforming the hinge 20 as shown in FIGS. 3 (A) to 3 (C). .
[0008]
In addition, the container 10 is configured to be able to hold a mount 30 for hanging a product between the container component parts 11 and 12 when the first container component part 11 and the second container component part 12 are sealed ( Figure 2). In the container 10, the mount 30 is sandwiched between the first container component 11 and the second container component 12, and the engagement of the second container component 12 is engaged with the engagement recess 13 of the first container component 11. The mating convex portion 14 is engaged with the concave and convex portions to hold the mount 30. The end portion of the mount 30 is brought into contact with the back surface concave portion of the outward protruding strip portion 24 of the hinge 20 (FIG. 3C).
[0009]
Therefore, according to the present embodiment, there are the following operations.
(Operation corresponding to claim 1)
(1) In order to improve the appearance of the hinge 20, the length of the connecting portions 21, 22 and the joint portion 23, which is the size of the hinge 20, is reduced, so that pulling at the hinge portion by molding a plastic sheet is performed. Even when the elongation rate does not increase so much and, as a result, the thickness of the hinge 20 does not become so thin, the hinge 20 is connected to the first and second container components 11, 12, which are substantially orthogonal to the connection portions 21, 22. The presence of the joint portion 23 that is substantially orthogonal to both the connection portions 21 and 22 and the outward protruding ridge portion 24 at the center of the joint portion 23 facilitates bending.
[0010]
(2) When the hinge 20 is bent and the first and second container constituting parts 11 and 12 are overlapped, the connecting parts 21 and 22 are bent at a substantially right angle with respect to the joint part 23 to form an acute bent part. At the same time, the outward projecting ridge 24 is maintained at the center of the joint (FIG. 3). Therefore, the rigidity of the bending cross section of the hinge 20 is high, and the warp of the longitudinal line of the hinge 20 can be suppressed.
[0011]
(3) When inserting a mount 30 for hanging a product between the first and second container components 11 and 12, the insertion end of the mount 30 collides with the concave surface on the back side of the ridge 24 of the hinge 20. To do. At this time, since the outline of the container 10 is partitioned by the protruding line portion 24 of the hinge 20, the end of the mount 30 that abuts the protruding line section 24 is substantially along the same line as the outline of the container 10, Appearance is good when the mount is removed.
[0012]
【The invention's effect】
As described above, according to the present invention, the size of the hinge can be reduced and the appearance can be improved, the bending can be facilitated, and the warping of the longitudinal line of the hinge can be suppressed.
