FIG. 1 is a perspective view showing a preferred embodiment of a container with a cap according to the present invention, FIG. 2 is a side view of the container with a cap, and FIG. 3 is a sectional view thereof. 1 and 2 show the respective parts separated and partially cut away, and FIG. 3 shows a state where the cap is screwed.

In this container with a cap, the cap 2 is attached to the container 1 by screwing, and basically, the container 1 and the cap 2 detachable from the container 1 are attached.
And a sheet body 3 for sealing the stored items.

The container 1 is formed in a substantially cylindrical shape with the peripheral edge of a circular bottom 10 integrally raised. A substantially cylindrical peripheral wall portion 11 rising from the peripheral edge of the bottom portion 10 is formed to have a small diameter portion 13 in which the outer circumference is formed to have a slightly smaller diameter for a predetermined length on the opening 4 side, and the small diameter portion 13 and the bottom portion 1 are formed.
A shoulder portion 12 is formed between the shoulder portion 12 and the zero side. The small-diameter portion 13 of the peripheral wall portion 11 is provided with a female screw portion 5. That is, the small-diameter portion 13 is formed with the screw 50 that spirals around the outer periphery thereof.
0 are provided opposite to each other.

The threads 50 are formed in a substantially trapezoidal cross section, and are provided so as to spiral in a clockwise direction from the edge surface 14 forming the peripheral edge of the opening 4 toward the shoulder 12. And constitutes a right-hand thread. Each thread 50 ...
Instead of spirally continuing to the shoulder 12, the shoulder 1
2 and is extended from the small diameter portion 13 in the longitudinal direction to be connected to the shoulder portion 12. The convex portion 15 extending in the vertical direction
Has a substantially rectangular cross section. Two threads 5
Are rounded about the outer circumference of the small-diameter portion 13 by a little more than half a circumference, and are symmetrical to each other with respect to the central axis of the container 1, so that each strip end is positioned axially symmetrically. It has become. Therefore, while the end portion of the other screw 50 is adjacent to the length portion connected to the convex portion 15,
A groove into which the corresponding screw 60 of the cap 2 is screwed is formed between the two screws 50.

The cap 2 is made of synthetic resin or the like having sufficient rigidity, and is formed into a substantially cylindrical shape corresponding to the container 1 with the peripheral edge of the circular ceiling portion 20 integrally lowered. An outer diameter of the substantially cylindrical peripheral wall portion 21 rising from the peripheral edge of the ceiling portion 20 is substantially the same as that of the peripheral wall portion 11 of the container 1, and an inner diameter thereof is slightly smaller than an outer diameter of the small diameter portion 13 of the container 1. It is formed large. On the inner surface 22 of the peripheral wall portion 21, a male screw portion 6 to be screwed with the female screw portion 5 formed in the small diameter portion 13 of the container 1 is formed. That is, the inner surface 22
Is formed with a corresponding screw thread 60 spirally circling the same, and the corresponding screw thread 60 is provided in two opposing mutually, and the two screw threads 50 provided in the container 1 are provided.
.. Are screwed into grooves between them.

When the cap 2 is attached to the container 1 as shown in FIG. 3, the cap 2 is attached to the sheet 3 on the edge surface 14 which forms the periphery of the opening 4 of the container 1 and the back surface of the ceiling 20. The gap S is maintained between the back surface 23 and the sheet body 3 without touching the space 23. At this time, the edge surface 24 that forms the periphery of the opening 7 of the cap 2 is slightly separated from the shoulder 12 of the container 1. These settings are made by appropriately selecting the height of the peripheral wall portion 21 and the formation position of the corresponding screw 60 on the inner surface 22.

The corresponding threads 60 have a substantially trapezoidal cross section in the same manner as the threads 50.
Are provided in a state extending spirally clockwise from the back surface 23 side to the edge surface 24 side forming the peripheral edge of the opening 7, and constitute a right-hand thread corresponding to the thread 50. The two corresponding threads 60... Are wound around the inner surface 22 for a length of about half a circumference, and are symmetrical with respect to the center axis of the cap 2. As a result, similar to the above-described threads 50. Each strip end is positioned to be axisymmetric.

The cross-sectional shape of the corresponding threads 60 corresponds to the shape of the groove between the two threads 50 provided on the container 1, and the dimensions are set so as to be slightly larger than the cross-section of the groove. It has been done. This is because when the corresponding screw 60 is screwed into the groove, the elasticity of the synthetic resin forming the corresponding screw 60 is used, and the corresponding screw 60 is compressed during screwing to increase friction. The frictional force locks each other in close contact. Ma
In addition, with regard to the corresponding screw threads 60, between the two screw threads 50 ...
As shown in FIG. 6,
To form a vent 63 extending along the length of the strip.
To improve the dimensional absorbability. to this
More stable and reliable friction force
It can improve the stability of locking and holding operation by force
In addition to the stability of the sealed state,
The friction of the screw during the screwing operation
Can be cut to ensure smooth closing and opening
Can also be maintained. The corresponding thread 60 is formed to have a slightly narrower end portion on the edge surface 24 side for a predetermined length. That is, the edge portion on the side of the edge surface 24 is
The side portion is formed narrower than the strip end over a predetermined length, and the distal end of the narrow portion 61 is first tightened to the female screw portion 5 side.

The sheet member 3 is formed of a thin film member made of a soft synthetic resin or the like, and is formed in a circular shape substantially the same as the outer diameter of the small diameter portion 13 of the container 1. This sheet 3 is a container 1
The container 8 is placed on the opening 4 in a state where a container 8 such as a cosmetic is fully stored therein, and is closely attached to the container 8 as shown in FIG. At this time, since the outer peripheral edge of the sheet body 3 is located on the edge 14 of the container 1, the opening 4 is properly closed.

In order to attach the cap 2 to the container 1, first, the opening 4 side of the container 1 and the opening 7 side of the cap 2 are opposed to each other, and the inner surface 22 of the cap 2 is fitted to the small diameter portion 13 of the container 1. When the cap 2 is rotated clockwise with respect to the container 1 and tightening is started, the tip of the narrow portion 61 of the corresponding screw 60 provided on the cap 2 becomes the screw 50 provided on the container 1. 4A, and eventually reaches the groove section between the two threads 50, and fits in as shown in FIG. 4 (A), and the narrow portions 61 slide in the groove section. During the insertion, there is a gap between the two threads as shown in FIG. 5 , so that the screw can be lightly and smoothly tightened without resistance.

Eventually, in the groove section between the two screws 50, the corresponding screw 60 following the narrow portion 61 will arrive and be fitted. As shown in FIG. 4 (B), the distal ends of the narrow portions 61 contact the convex portions 15 connected to the toes of the threads 50 and cannot be further tightened. At this time, thread 5
As shown in FIG. 6 , the screwing state between 0 and the corresponding thread 60 is in close contact with no gap, so that it can be tightened with an appropriate resistance without play. Also, as described above, the corresponding threads 60 are compressed at the time of screwing, so that they can be locked in close contact with each other by the frictional force resulting therefrom. As a result, during transportation or when the container 1 falls, etc. Even if there is, the state where the cap 2 is tightened can be maintained. Ma
In addition, the bent portion 63 is formed on the corresponding screw 60.
Therefore, as described above, the locking / holding operation is also safe from this configuration.
Qualities can be improved and smooth tightening and opening
Operation can be ensured.

On the other hand, the cap 2 attached to the container 1
To remove the cap 2, simply rotate the cap 2 in a counterclockwise direction, and even in this removing operation, the cap 2 can be rotated lightly and smoothly without resistance, and the narrow portions 61 are inclined obliquely upward to the right along the threads 50. Since it is guided, the cap 2 can be removed soon.

As described above, when the cap 2 is tightened, the tip of the narrow portion 61 on the cap 2 side is stopped by abutting on the convex portion 15 on the container 1 side. The screwing of the two screw portions 5 and 6 is stopped at a predetermined amount, so that the tightening of the cap 2 does not become excessive. In the stopped state of this screw engagement, FIG.
As shown in (2), since a predetermined gap S is maintained between the sheet 3 and the cap 2, the back surface 23 of the cap 2 does not touch the sheet 3. Therefore, when the cap 2 is tightened, as well as when the cap 2 is removed, the sheet body 3 is not further turned, and as a result, the sheet body can be prevented from being twisted, and the appearance of the storage object 8 is not impaired. Can be protected. And such an operation does not require special attention in tightening and removing the cap 2,
Easy to operate and excellent in operability.

At the time of mounting, the cap 2
Since the edge surface 24 of the container 1 is separated from the shoulder portion 12 of the container 1, the cap 2 does not become difficult to open due to biting. Further, at this time, since the threaded state is tightly closed without any gap due to the compression between the threads 50 and the corresponding threads 60, the container 1 can be sealed, and the sealing property is improved. Excellent.

In the embodiment described above, the side of the corresponding screw thread 60 on the back surface 23 side at the edge end portion on the edge surface 24 side is formed to be narrower by a predetermined length than the stripe end. Instead, for example, as shown in FIG.
Conversely, the opposite side portion, that is, the side portion on the edge surface 24 side may be formed to be similarly narrower than the strip end. Even in the narrow portion 62 formed by shifting to the opposite side in this manner, light and smooth screwing can be similarly performed, and the same effect as that of the above embodiment can be obtained.

Further, the configurations of the female screw portion 5 and the male screw portion 6 are not limited to the so-called double thread as in the above embodiment. For example, it can be appropriately configured such as a three-start screw.
