Description

  The present invention relates to the shape of a boss portion such as a lid in a cosmetic container or other container body.

It is conventionally known to form a boss portion on a synthetic resin lid (see, for example, Patent Document 1), and in order to reinforce the vicinity of the base of the boss, the intersection of the substrate and the base of the boss The shape structure of the boss | hub part which made the part the shape of the circular arc curve is also known conventionally (for example, refer patent document 2).
Japanese Utility Model Publication No. 61-145620 Japanese Utility Model Publication No. 3-41988

  However, the bosses described in Patent Documents 1 and 2 are all made of synthetic resin, and the strength of the boss base is not sufficient.

  In order to solve the above problems, the present invention is a cosmetic container reinforced by connecting a base of the boss portion to the back surface of the lid as an arc curve and providing a plurality of radially extending reinforcing ribs. It aims at providing boss parts, such as a lid used for a container body.

  In order to solve the above-described problems, the present invention provides a boss portion provided on the back surface of a lid body or the like as a boss portion of a lid body, and the boss portion extends radially from the projection portion. A configuration including a reinforcing rib and having a plurality of boss portions arranged along the periphery of the lid is adopted.

  As a connection part between the lid and the boss part, a configuration characterized in that the intersection of the back surface of the lid and the boss part is connected by an arc curve, and as a position of the reinforcing part, the lid is The configuration is characterized in that it is formed by a curved surface protruding from the center, and the surface of the reinforcing rib is provided so as to be located above the lower surface of the peripheral edge of the lid.

The boss part of the lid body of the present invention is connected to the back surface of the lid body as a circular arc curve at the base of the boss part and is provided with a plurality of reinforcing ribs. There is no problem even if they are combined.
Since the surface of the reinforcing rib is located above the lower surface of the peripheral edge of the lid provided in a curved shape, the reinforcing rib is not visible from the outside, and the surface of the reinforcing rib can serve as a stopper Can now also.

Next, an embodiment of a boss portion such as a lid of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the lid of the present invention includes a plate-like lid 1 and a boss portion 2 disposed on the lid.

The lid 1 is formed by a disk-shaped thin plate 4 having a curved surface 3 with a raised central portion, a peripheral portion 5 is curved downward, and a lower surface thereof is a horizontal surface 7 having a circular outer peripheral edge 6. ing.
The boss portion 2 is located on the back surface of the lid 1 along the outer peripheral edge 6 at a certain distance inward, and is provided with a plurality of hollow protruding portions 8 disposed at equal intervals, It consists of reinforcing ribs 9 extending radially from the base portion along the back surface of the lid body 1 and having a surface 9a as a horizontal plane.

  The intersection of the back surface of the lid 1, the protrusion 8 and the reinforcing rib 9 is connected by an arc curve 10, and the intersection of the protrusion 8 and the surface 9 a of the reinforcement rib 9 is an arc curve 11. It is connected.

The upper end of the protruding portion 8 protrudes from the back surface of the lid 1, and the surface 9 a of the reinforcing rib 9 is located above the lower surface of the peripheral portion 5.
A bulging portion 12 is provided at the outer peripheral end portion of the protruding portion 8, and is engaged with an attachment hole drilled in the container body.

Next, the function and effect of the above configuration will be described.
Since the protrusion 8 of the boss 2, the reinforcing rib 9 and the back surface of the lid 1 are connected by the arc curve 10, there is no sink at the time of molding, and the boss is reinforced by several reinforcing ribs 9. 2 was protected from breakage due to impact or the like, and a bulging portion 12 was attached to the tip of the protruding portion 8 to facilitate coupling with the container body and other parts.

Moreover, since the lid body 1 has a curved surface 3 protruding in the center and the reinforcing rib 9 is provided on the inner side of the lower surface of the peripheral portion 5 of the lid body 1, the reinforcing rib 9 becomes an obstacle as a lid body of the cosmetic container. It can be combined with the container body and other articles without any problems, and is optimal for decoration.
Moreover, since the surface 9a of the reinforcing rib 9 is a horizontal plane, it can serve as a positioning stopper for the container body and other articles and the coupling portion.

  In the embodiment, the shape of the lid is circular. However, the shape of the lid may be oval or square in addition to the circle, and the cross section is U as described in Patent Document 1. It may be a letter-shaped three-dimensional lid.

  Further, the outer peripheral surface of the protruding portion 8 of the boss portion 2 may be tapered, and furthermore, the protruding portion 8 of the boss portion 2 may be provided with several cuts (not shown). Bonding with a container body such as a body or other articles can be further facilitated.

  The boss portion of the present invention connects the base of the protruding portion to the back surface of the lid body by an arc curve, and by providing a plurality of reinforcing ribs, it can protect from destruction due to impact etc. without causing sink marks. It can be widely used as a decorative body set with other parts.

It is explanatory drawing of the cover body of this invention, (a) is a partial cross section front view, (b) is a bottom view. It is an enlarged view of a boss | hub part, (a) is a partial cross section front view, (b) is a bottom view.
