Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a cap with a lid plate or a container with a lid plate that is elastically inverted in the sense that it includes a container body.

"Prior Art" Conventionally, many containers with lid plates that are elastically inverted are known, and a typical one is a so-called three-point hinge cap or container. The cap or container has a pair of left and right cap main bodies or container body upper ends and a rear lower end of a lid plate placed on the upper surface of the cap body and the upper end of which is closed, with a proper gap. First of
While connecting with a hinge, the lower end of the inverted L-shaped elastic plate provided between the first hinges is connected to the rear part of the cap body or the like below the first hinge via the second hinge, and the other end of the elastic plate is connected. The third part is provided on the upper surface of the lid plate in front of the first hinge.
It is connected via a hinge.

[Problems to be Solved by the Invention] The conventional so-called three-point hinge container or the like has a drawback in that the elastic plate is largely exposed to the outer surface of the cap or the like, which impairs the appearance.

The inventors of the present application have previously devised the container and the like of Japanese Patent Application No. 62-81274 and Japanese Utility Model Publication No. 5-42043) as a container and the like from which the above drawbacks are removed. The container or the like includes a container body having a mouth on the upper surface, a lid plate fitted to the upper surface of the container body, a lower end of the plate portion at the rear part of the container body, and an upper end of the plate portion at the rear part of the lid plate, and a pair of left and right, respectively. When viewed from the rear of the container and the like, the lower left and right hinges are tapered so that the middle side rises, and the upper left and right hinges are tapered so that the middle side is lowered, and the upper side. When viewed from above, the upper and lower left and right hinges are tapered so that the middle side projects rearward, and when attaching and detaching the lid plate to and from the container body, the elastic connecting plates center around the lower left and right hinges, and the upper and left and right hinges center. The lid plate is provided so as to rotate by elastic inversion of the elastic connecting plate.

The left and right parts of the elastic connecting plate may be connected to each other via a hinge vertically provided in an intermediate part, or may be formed of two elastic plates without connecting them. When connected through, the vertical hinges appear as ridges on the rear surface of the container or the like, which is not preferable in appearance, and when formed with two elastic plates, the thickness of the left and right elastic connecting plates is reduced. Since it is difficult to form the same, there is a possibility that a time lag occurs when the elasticity is reversed and the consumer's confidence in the product is impaired.

According to the present invention, a gap is provided between the left and right parts of the elastic connecting plate, and the erection plate is connected into the gap, and the left and right ends of the erection plate and the inner parts of the left and right elastic connecting plates are connected via hinges. It is provided so that the above-mentioned defects can be eliminated.

"Means for Solving the Problem" A container body 1 or the like having a mouth portion 2 on the upper surface, a lid plate 4 which is fitted on the upper surface of the container body or the like by closing the mouth portion, a rear portion of the container body or the like The lower ends of the pair of left and right plate parts with an appropriate gap between
Also, the upper ends of the respective plate parts are connected to the rear part of the cover plate via the thin first, second, third and fourth hinges, and the inner edge of each of these elastic connection plates. And a erection plate 14 whose left and right side edges are connected to each other via thin fifth and sixth hinges 12 and 13. When the lid plate 4 is attached to or detached from the container body or the like, the elastic connecting plates 7 and 7 are For the container body and the lid body, the upper and lower first to fourth hinges are centered, and for the erection plate 14, the intermediate fifth and sixth hinges are centered to be elastically reversed to elastically connect plate 7, 7, the erection plate 14 and the lid 4 are rotatable, the first and second hinges 8 and 9 on the lower left and right when viewed from the rear are tapered so that the middle side rises, and the third and fourth hinges on the upper and left. 10, 11 has a taper shape in which the middle side descends, and further, the first to fourth hinges have a taper shape in which the middle side projects rearward when viewed from above. Formed individually.

[Operation] When the cover plate is closed, the elastic connecting plates 7 and 7 are tapered as shown in FIG. The upper and left third and fourth hinges 10 and 11 are formed in a taper shape in which the middle side descends, and the first to fourth hinges are formed in a taper shape in which the middle side projects rearward when viewed from above. Therefore, if the front part of the cover plate 4 is pushed up from the closed state,
Elastic connection plates 7, 7 as in the case of the invention of Japanese Patent Application No. 62-81274
The tensile force is applied to each outer side of the and the compressive force is applied to each inner side.
Each of them acts, and after the thought point, a restoring force acts, so that the lid plate 4 is moved to the rear of the container body 1 or the like and elastically inverted. Even when the lid is closed, the elastic connecting plates 7 and 7 are elastically inverted. The left and right elastic connecting plates 7 and 7 are provided on the left and right side edges of the erection plate 14 provided in the middle thereof and the fifth and sixth hinges 12 and 1, respectively.
Since they are connected via 3, the elastic inversion of both elastic connecting plates 7, 7 can be performed simultaneously.

"Example" 1 is a container body or the like having a mouth portion 2 on its upper surface. The container body or the like may be, for example, a cap body that is screwed into the mouth or neck of a bottle or the like, and in this case, the lower end surface of the peripheral wall 3 is opened and the peripheral wall is screwed into the mouth or neck of the container body. Become. Alternatively, the container body may be used, and in this case, the lower end surface of the peripheral wall is closed by the bottom wall.

Reference numeral 4 denotes a lid plate for closing the mouth portion 2 of the container body or the like and fitting it to the upper surface of the container body or the like. A finger hanging piece 5 is attached to the lower end of the front surface, and a mouth stopper 6 is hung from the lower surface of the central portion of the top wall. is doing.

The container body and the lid plate are connected to each other by elastic connecting plates 7, 7 at their rear portions with an appropriate gap left and right.
The lower and upper ends of these connecting plates are connected to the rear part of the container body and the rear part of the cover plate via thin first, second, third and fourth hinges 8, 9, 10, 11 respectively. As shown in FIG. 5, the hinges are the first and the second left and right when viewed from the rear.
The hinges 8 and 9 have a tapered shape in which the middle part rises, and the upper and left bent third and fourth hinges 10 and 11 have a tapered shape in which the middle part descends. Also, as seen from FIG. The left and right hinges are each formed in a tapered shape with the middle side protruding rearward.

A bridge plate 14 is provided between the elastic connecting plates 7 and 7 by connecting the left and right side edges through thin fifth and sixth hinges 12 and 13 at the inner edges thereof.

In addition, the above-mentioned tapered hinge includes the container body 1, the lid plate 4, the erection plate.
This is for elastically reversing the elastic connecting plates 7, 7 with respect to 14, and the taper is relatively fixed vertically. The container of the present invention and the like are integrally molded of synthetic resin material.

"Effect of the device" Since the present invention has the already described configuration, compared to the conventional connection between the container body and the lid by the three-point hinge, the container body and the lid can be connected only by the rear surface portion, so that the container and the like In the case of a three-point hinge, since the refraction angle portion of the first hinge is projected, the corner portion may injure the hand. Nothing. With respect to the invention of Japanese Utility Model Application No. 62-81274, by providing the erection plate 14, a gap can be provided between the pair of left and right elastic connection plates 7, 7, and by doing so, 2 hinges 8 and 9
Also, the taper when the third and fourth hinges 10 and 11 are viewed from above can be easily formed, and when the left and right elastic connecting plates 7 and 7 are separately provided with a gap therebetween, the left and right elastic connecting plates are connected. Due to the slightly different thickness of the plates, there was a drawback that the elastic inversions were not simultaneous and the time lag was likely to occur, but in the present proposal, by elastically connecting the left and right elastic connecting plates, they can be elastically inverted at the same time. Is possible.
