Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cap attached to a container for dispensing salt, pepper, etc.

"Problems to be Solved by Prior Art and Ideas" Conventionally, this type of cap has a dispensing hole in the front part of the top wall, which has a vertical wall that can fit into the mouth of the container, and a dispensing hole in the rear part of the top wall. The cap main body, which has recesses opening on the upper and rear sides, and a lid plate placed on the upper surface of the top wall are pivoted at the upper front part of the recess, and the cap body is pivoted at the upper front part of the recess, A cap is known in which the front part of the lid plate that closes the dispenser hole is swung upward by pushing the rear part of the cover plate downward into the recess, thereby opening the dispenser hole.

In the conventional cap described above, a metal coil spring is used to always bias the lid plate in the direction of closing the lid, which increases the number of parts and increases costs.

Taking these points into consideration, the present applicant has already proposed a cap with a lid plate (Utility Application No. 47490/1983).
Publication No. 3-43166〓).

This cap has a concave portion with an open top and rear surface formed at the rear of the cap body which is removably fitted to the mouth of the container, and a first semicircular arc piece formed from the front wall of the concave portion. An elastic arm is made to protrude in both up and down directions with a gap between the lower arm and the bottom wall of the recess, and second and third arcuate pieces are inserted from the tips of these arms through the first and second bending parts. By protruding and connecting the tips of the second and third arcuate pieces via the third bending part, the first, second and third arcuate pieces form a circular ring, and from the outer surface of the second arcuate piece. , a lid plate protrudes from the upper surface of the top wall of the cap body and closes a stored object pouring hole.

This cap has a simple structure and can be manufactured at low cost because it does not use metal coil springs. In this case, the lid is configured to be pressed down on the top surface of the lid plate, making it somewhat difficult to open and close the lid with one hand, and there was room for improvement in this respect.

The present invention was devised in consideration of the conventional situation, and it can be manufactured at low cost without using metal coil springs, and the lid can be easily opened and closed with one hand for shaker containers. The purpose is to propose a cap.

"Means for Solving the Problems" In order to solve the above-mentioned problems, the cap of the present invention has a top wall 3 on which a peripheral wall 2 for fitting the opening of the container body is vertically disposed.
It has a cap main body 1 having a drawing hole 4 in the front part and a recess 5 with an open top and rear part in the rear part of the top wall, and a lid plate 8 placed on the upper surface of the top wall. It consists of a synthetic resin lid plate member 7 having a lid plate mounting part 9 housed in the recess on the back surface of the rear part of the lid plate, and a lid plate member 7 on the left side of the cap main body recess 5;
Bearings 6, 6 are formed on both right sides, and the cover plate 8
Slits 10, 10 are bored in the left and right parts of the rear part from the rear end of the cover plate to the front, and the cover plate attachment part 9 is
In this case, pins 12, 12 attached to the lower portions of both the left and right end surfaces of the vertical plate portion 11, which is vertically hung from the lid plate portion inside the slits, are rotatably fitted into the bearings 6, 6. By rotating the cover plate around the pins 12, 12, both side portions of the cover plate outside the slits 10, 10 are elastically deformed, and the upper end portions on both sides of the recess at the rear of the cap main body peripheral wall 2 or While getting over the upper surface of the bearings 6, 6,
The cover plate 8 is configured so as to be able to be held in an upright state by being pressed against the rear wall surface of the crossing portion.

"Operation" When in use, for example, by holding the body of the container and pushing down the rear end of the lid plate 8 with your thumb, the lid plate is rotated from the state shown by the solid line in FIG. 1 in the lid opening direction. Both side portions of the rear part of the plate are elastically deformed to overcome the upper surfaces of the bearings 6, 6, etc., and finally press against the rear wall surface of the bearings etc. by the elastic restoring force to hold the cover plate 8 in an upright state. Drill the drawing hole 4 (see the imaginary line in FIG. 1). Therefore, the lid can be opened easily with one hand.

Further, after using the container, for example, after placing the container on a table or the like, the opened lid plate may be closed by pressing down on the front part of the lid plate. As a result, the cover plate is held in a closed state by the elastic restoring force of the above-mentioned both side portions, thereby closing the dispense hole. Therefore, the lid can be easily closed with one hand.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 and 2 show an embodiment of the present invention,
The cap of the present invention is composed of a cap body 1 and a synthetic resin cover plate member 7 with a cover plate mounting portion 9.

The cap body 1 has a top wall 3 extending from the upper edge of a rectangular cylindrical peripheral wall 2, a plurality of drawing holes 4 in the front part of the top wall 3, and a recess 5 with an open top and rear part in the rear part. , respectively. In addition, the recessed portion 5
The bearing hole 6b is provided in a block-like manner protruding upward from the lower surfaces of both sides, and is inserted into the bearing hole 6b from the upper surface via the guide groove 6a.
A pair of bearings 6, 6 are provided.
The width of the entrance of the bearing hole 6b is set smaller than the outer diameter of a pin, which will be described later, in the cover plate member 7, so that the pin does not easily slip out upward.

Furthermore, an engagement groove 16 is provided around the inner surface of the peripheral wall 2 to elastically engage with an engagement protrusion 15 provided around the outer surface of the mouth 14 of the container body 13.

Further, the peripheral wall 2 is configured to protrude slightly upwards from the upper surface of the top wall 3 and the upper surfaces of the bearings 6, 6, except for the rear surface of the recessed portion 5.

The cover plate member 7 has a rectangular cover plate 8 that fits on the inner surface of the protruding peripheral wall portion, and has a plurality of protrusions 18 that loosely fit into the dispense hole 4 on the front back surface thereof. Further, slits 10, 10 are bored in the left and right portions of the rear portion of the cover plate from the rear end to the front. or,
On the rear edge of the surface of the lid plate 8 located inside both slits, there is a protrusion 1 for pushing down the rear part of the lid plate when opening the lid.
7 is attached. Further, pins 1 to be fitted into the bearings 6, 6 are provided at the lower portions of both left and right end surfaces of the vertical plate portion 11 hanging from the back surface of the cover plate inside the slits.
A cover plate attachment part 9 with attached numbers 2 and 12 is integrally extended.

The respective pins 12, 12 are rotatably fitted into the bearings 6, 6, and the upper surface of the drawing hole is covered by the front part of the cover plate 8 for mounting.

Incidentally, each of the above members is made of synthetic resin material.

``Effects of the invention'' As explained above, the cap of the present invention has the described structure, and a part of the lid plate member has a leaf spring function, and the leaf spring function allows the lid to be opened and closed. Since it is configured to be able to hold the cap, there is no need for a metal coil spring, and since the cover plate member, including the cover plate attachment part, can be integrally molded with synthetic resin, it is much cheaper than a cap with a coil spring. It can be manufactured in Further, the lid plate can be easily opened and closed with one hand, and once opened, the lid plate can be automatically held open, making it extremely user-friendly.
