Description

DETAILED DESCRIPTION OF THE INVENTION “Industrial field of application” The present invention relates to a container with a lid plate that is elastically inverted. In the present specification, the term “container or the like” is used to include both a cap and a container.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, many containers with lid plates that are elastically inverted are known, and typical ones thereof are so-called three-point hinge caps or containers. However, the cap has a drawback that the L-shaped elastic plate is largely exposed to the outer surface of the cap or the like, which impairs the appearance. As a container or the like which does not have the drawbacks, the present applicant has applied for a container or the like of Japanese Utility Model Application No. 62-81274 (see Japanese Utility Model Publication No. 5-42043). The container or the like has a container or the like having a mouth portion on the upper surface, a lid plate fitted to the upper surface of the container or the like, a lower end of the plate portion at the rear portion of the container or the like, and an upper end portion of the plate portion at the rear portion of the lid plate. When viewed from the rear of the container with a lid plate, 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. Also, when viewed from above, the upper and lower left and right hinges are each formed in a taper with the middle side protruding rearward, and when attaching and detaching the lid plate to and from the container, the elastic connecting plates are centered on the lower left and right hinges, and the upper and left and right hinges. The lid plate is provided so as to rotate about the hinge 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 via the above, the above-mentioned vertical hinge appears as a ridge on the rear surface of the container with the lid plate, which is not desirable in appearance. When formed by two elastic plates, the left and right elastic connecting plates are connected to each other. Since it is difficult to form the same thickness, there is a possibility that a time lag may occur when the elasticity is reversed and the consumer's confidence in the product may be impaired.

In order to eliminate the above-mentioned drawbacks, further, in Japanese Patent Application No. 63-61732 (see Japanese Utility Model Laid-Open No. 1-168454), a gap is provided between the left and right parts of the elastic connecting plate, and a plate is installed in the gap. I applied for a container with a lid plate in which both the left and right parts of the erection plate and the inner parts of the left and right elastic connection plates were connected by hinges.However, in the case of the container etc., the ridges on the rear surface of the container etc. are eliminated. Although you can
It was found that the time lag of the elastic reversal of the left and right elastic connecting plates could not be completely eliminated and there is still room for improvement.

In this plan, instead of the erection plate provided by hinge-connecting the left and right ends to the inner edges of the left and right elastic connecting plates, the upper part of the rear surface of the container and the like and the rear surface of the lid plate are shortened between the elastic connecting plates. By hinge-connecting the lower end and the upper end of the elastic connecting plate, the time lag at the time of elastic reversal of the left and right elastic connecting plates is eliminated.

"Means for Solving the Problem" A container 1 or the like having a circular cross-section having a mouth 2 on the upper surface, and a container 1 having the same cross-sectional shape as the container etc. The lid plate 4 and the lower end of the plate portion at the rear portion of the container and the like, and the upper end portion of the plate portion at the rear portion of the lid plate are respectively thin first,
First elastic connecting plate 9 connected via second hinges 9a, 9b
With a proper gap between the left and right sides of the first elastic connecting plate, the lower end of the plate part is the rear part of the container or the like, and the upper end of the plate part is the rear part of the cover plate 4.
Third, fourth, fifth and sixth hinges 10a, 11a, 10 respectively
a pair of left and right elastically connected second and third elastic connecting plates 10 and 11 which are longer than the first elastic connecting plate, and when the lid plate 4 is opened and closed with respect to the container, Each elastic connecting plate is elastically reversible so that the line passing over the third, first and fourth hinges 10a, 9a, 11a on the lower side when viewed from the rear of the container is a curved line extending upward, and the upper side. The lines passing above the fifth, second and sixth hinges 10b, 9b and 11b are curved lines projecting downward, and these two curved lines are vertically symmetrical.

[Operation] When the front portion of the lid plate 4 is pushed rearward and upward with respect to the container 1 or the like from the state of FIG. 2, the first, second, and third elastic members that connect the container and the lid plate to each other at the rear side. After the connecting plates 9, 10 and 11 have passed through the reflection point, they are elastically inverted as shown in FIG. 1 to move the lid 4 backward to open the upper surface of the container or the like. When the front portion of the lid plate located at the rearmost position in the state of FIG. 1 is pushed upwards and forwards, the lid plate 4 elastically reverses and closes the upper surface of the container or the like as shown in FIG. To do.

"Example" 1 is a container or the like having a mouth portion 2 on its upper surface. The container etc.
For example, it may be a cap body for screwing into the mouth and neck of a bottle or the like. In this case, the lower end surface of the peripheral wall 3 is opened and the peripheral wall is screwed into the mouth and neck of the container body. 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. The container, etc. shall have a circular cross section.

Reference numeral 4 denotes a lid plate having the same cross-sectional shape as the container or the like, which closes the mouth 2 of the container or the like and fits on the upper surface of the container or the like, and hangs the peripheral wall 6 from the peripheral edge of the top plate 5 and the lower front surface of the front part of the peripheral wall. Has a finger hanging concave portion 7, and a stopper 8 for opening and closing the mouth portion 2 such as a container is hung from the lower surface of the top plate 5.

The rear portion of the container or the like and the rear portion of the lid plate are connected by the first, second and third elastic connecting plates 9, 10, 11 via thin hinges. The first elastic connecting plate 9 is located between the second and third elastic connecting plates 10 and 11 provided on the rear left and right, and its lower end is connected to the rear part of the container or the like via the first hinge 9a, and its upper end. The second hinge 9b
It is connected to the rear part of the cover plate via. Second and third elastic connecting plate 1
Numerals 0 and 11 are equidistant from the first elastic connecting plate 9 and their lower ends are containers and the like, and their upper ends are lid plates.
The fourth, fifth and sixth hinges 10a, 11a, 10b and 11b are connected to each other. Third, first and fourth hinges located below them
10a, 9a, 11a are fifth, second and sixth hinges 10b which are located on the curved line which extends upward as shown in FIG. , 9b, 11b
Are provided so that the lines passing on the hinges are respectively located on the curved lines extending downward when viewed from the rear. Since the container and the lid plate have the same circular cross-sectional shape, the curved line passing over the hinges located above and below the container plate and lid plate as seen from above as shown in FIG. It will be located on the curved line that extends backward along the rear surface of the peripheral wall. Each of the elastic connecting plates is provided with a recess in the rear surface of each peripheral wall into which the elastic connecting plates are fitted so that the rear surface or outer surface thereof is flush with the rear surface of each peripheral wall of the container or the like and the cover plate when curved. Good.

When the elastic connecting plates 9, 10, 11 are viewed from above in the closed state of the cover plate, their respective cross-sections are located on the curved curve of the rearward overhang as shown in FIG. As shown in the figure, when the lid plate is open, each cross-section is located on the curved line of the overhang. On the other hand, the lid plate is elastically inverted.

[Advantage of the Invention] The present invention is configured as described above. Since the first, second, and third elastic connecting plates are attached to the rear surfaces of the container and the lid and the lid plate, the lid plate is provided by the conventional three-point hinge mechanism. Unlike the case of a container, the elastic connecting plate is not exposed on the upper surface of the cover plate and does not damage the appearance, and even when compared to the container of the above-mentioned Japanese Utility Model Application No. 63-61732, the container and the cover body are Since they are connected at three points on their rear surfaces, the second on the left and right,
Even if the thicknesses of the third elastic connecting plates 10 and 11 are slightly different, they can be elastically reversed at the same time, so that consumer confidence in the product can be obtained.
