[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap-equipped container in which a cap is screwed onto the container, and more particularly to a cap-equipped container in which an opening of the container is covered with a sheet to seal a stored item.

[0002]

[Prior Art]

 As a container with a cap, for example, as shown in FIG. 8, a female screw portion 500 is provided on the outer circumference of a cylindrical container 100, and a male screw portion 600 is provided on the inner circumference of a cylindrical cap 200 facing the container 100. It is known that the cap 200 is attached to the container 100 by providing the female screw portion 500 and the male screw portion 600 by screwing. The opening of the container 100 is covered with the sheet body 3 to seal the storage item 8.

[0003]

[Problems to be solved by the device]

 However, in the related art, in order to improve the hermeticity, the cap 200 is tightened so that the sheet body 3 is sandwiched between the back surface of the cap 200 and the opening edge of the container 100, so that the cap 200 and the container 100 are separated from each other. The sheet bodies 3 are pushed against each other, so that the sheet body 3 is rotated further not only when the cap 200 is tightened but also when the cap 200 is detached, which may impair the appearance of the stored item 8.

Therefore, it has been considered to secure a gap between the cap 200 and the back surface of the sheet body 3 so that the back surface of the cap 200 is not pressed against the sheet body 3. For example, as shown in FIG. 9, by extending the lower edge portion of the cap 201 toward the container 100 and pressing the lower edge portion against the corresponding step portion of the container 100 when tightened, the back surface of the cap 201 and the sheet body are A configuration is conceivable in which the space S 1 is held between the space 3 and the space 3. However, in this configuration, since the extended lower edge of the cap 201 is pressed against the corresponding step of the container 100, when the screw is tightly tightened, the screw portions 500 and 600 are bitten each other, and the cap 201 is opened. There was an inconvenience that it became difficult.

The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent the seat body from twisting and to easily tighten and remove the cap, which is excellent in operability. It is to provide a container with.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a cap having a container having a threaded portion, a sheet body that covers an opening of the container and seals a stored item, and a corresponding threaded portion that is screwed into the threaded portion of the container. In a container with a cap including: When the corresponding screw part of the cap is screwed into the screw part of the container, a gap is held between the sheet body and the cap to stop the screwing. It is characterized in that it is provided with a blocking means and a holding means for tightening both screw parts when the screwing by the blocking means is stopped.

[0007]

[Action]

 The operation of the present invention will be described. When the cap is tightened, the screwing is stopped by the blocking means while the gap is held between the sheet body and the cap, and the stop is stopped by the holding means. Retained. Therefore, the tightening of the cap does not become excessive, and a gap is maintained between the seat body and the cap so that the cap does not touch the seat body. Further, in the case of holding the stop by the holding means, the screwed state between the threaded portion of the container and the corresponding threaded portion of the cap is tightened, so that the container can be sealed.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 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. FIG. 1 and FIG. 2 show the respective parts separated and partially cut away, and FIG. 3 shows a state in which the cap is screwed.

This container with a cap is one in which the cap 2 is attached to the container 1 by screwing, and basically, the container 1 and the cap 2 which is detachable from the container 1 and the receipt are sealed. And a sheet body 3 for

The container 1 is formed into a substantially cylindrical shape by integrally raising the peripheral edge of a circular bottom portion 10. The substantially cylindrical peripheral wall portion 11 rising from the peripheral edge of the bottom portion 10 has a small diameter portion 13 formed by forming the outer diameter to a slightly smaller outer diameter for a predetermined length on the opening 4 side. A shoulder 12 is formed between the two. A female screw portion 5 is formed on the small-diameter portion 13 of the peripheral wall portion 11. In other words, the small-diameter portion 13 is formed with screw threads 50 that spiral around the outer periphery thereof, and in this embodiment, two screw threads 50 are provided facing each other.

Each of the screw threads 50 has a substantially trapezoidal cross section, and is provided in a state of spirally extending clockwise from the edge surface 14 side forming the peripheral edge of the opening 4 toward the shoulder 12 side. The right-hand thread. Each thread 50 is not directly connected to the shoulder portion 12 in a spiral shape, but is stopped at a position slightly apart from the shoulder portion 12 and then extended along the longitudinal direction of the small diameter portion 13 from there. And is connected to the shoulder portion 12. The convex portion 15 extending in the vertical direction has a substantially rectangular cross section. The two screw threads 50 are circulated around the outer circumference of the small-diameter portion 13 by a length of about a half circumference, and are symmetrical with respect to the center axis of the container 1, and as a result, each of the ends is axial. It is located symmetrically. Therefore, the thread end portion of the other screw thread 50 is adjacent to the thread length portion connected to the convex portion 15, and a groove portion into which the corresponding thread thread 60 of the cap 2 is screwed is formed between both thread threads 50. There is.

The cap 2 is made of a synthetic resin or the like having a sufficient rigidity, and the peripheral edge of the circular ceiling portion 20 is integrally lowered so as to be formed into a substantially cylindrical shape corresponding to the container 1. An outer diameter of the substantially cylindrical peripheral wall portion 21 falling 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 the outer diameter of the small diameter portion 13 of the container 1. Largely formed. On the inner surface 22 of the peripheral wall portion 21, a male screw portion 6 to be screwed with a 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 thread 60 that spirals around the inner surface 22. The corresponding thread 60 is provided in two rows facing each other, and is provided in the container 1. It is adapted to be screwed into the groove portion between the two screw threads 50 ....

As shown in FIG. 3, when the cap 2 is attached to the container 1, the cap 2 is attached to the sheet body 3 on the edge surface 14 forming the peripheral edge of the opening 4 of the container 1, and the back surface of the ceiling portion 20. The space S is held between the back surface 23 and the sheet body 3 without touching 23. At this time, the edge surface 24 forming the peripheral edge of the opening 7 of the cap 2 is also 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 thread 60 on the inner surface 22.

Similar to the thread 50, the corresponding thread 60 has a substantially trapezoidal cross section, and extends from the rear surface 23 side of the ceiling portion 20 toward the edge surface 24 side forming the periphery of the opening 7. It is provided in a state of spirally extending clockwise and constitutes a right-hand thread corresponding to the thread 50. The two corresponding screw threads 60 ... Circulate the inner surface 22 by a length of about half a circumference, and are symmetrical with respect to the central axis of the cap 2. As a result, similar to the screw threads 50 described above. The ends of each line are arranged symmetrically.

The cross-sectional shape of the corresponding thread 60 corresponds to the shape of the groove between the two thread 50 provided in the container 1, and the dimensions are set so as to be slightly larger than the groove cross section. Has been done. This is because when the corresponding thread 60 is screwed into the groove, the elasticity of the synthetic resin forming the corresponding thread 60 is used, and the thread 60 is compressed during screwing to increase friction. This friction force causes them to be locked in close contact with each other. In addition, each corresponding thread 60 is formed such that the thread end portion on the edge surface 24 side is slightly narrower than a predetermined length. In other words, the edge portion on the edge surface 24 side is formed so that the side portion on the back surface 23 side is narrower than the edge over a predetermined length, and from the tip of the narrow width portion 61 to the female screw portion 5 side. It will be tightened.

The sheet body 3 is formed of a thin film member made of a soft synthetic resin or the like, and is formed into a circular shape having substantially the same outer diameter as the small diameter portion 13 of the container 1. The sheet body 3 is placed on the opening 4 in a state where the container 8 such as cosmetics is fully stored in the container 1, and is brought into close contact with the container 8 as shown in FIG. At this time, since the outer peripheral edge portion of the sheet body 3 is located on the edge portion 14 of the container 1, the opening 4 is satisfactorily closed.

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. Then, when the cap 2 is rotated clockwise with respect to the container 1 to start tightening, the tips of the narrow width portions 61 of the corresponding screw threads 60 provided on the cap 2 are screwed on the thread 50 provided on the container 1. .. and then reaches the groove section between the two screw threads 50, and is fitted as shown in FIG. 4 (A), and this narrow portion 61. During sliding, there is a gap between both screw threads as shown in Fig. 5 (A), so it can be tightened lightly and smoothly without resistance.

Eventually, in the groove section between the two screw threads 50, the corresponding thread 60, which follows the narrow width portion 61, reaches the original thread length portion and is fitted therein. At the same time, the tips of the narrowed portions 61 ... Abut on the projections 15 that are continuous with the toes of the screw threads 50, as shown in FIG. 4 (B), and cannot be tightened further. At this time, the thread 50 and the corresponding thread 60 are screwed together as shown in FIG. 5 (B) without any gap, so that they can be tightened with proper resistance without play. .. Further, as described above, since the corresponding thread 60 is compressed during screwing, the frictional force caused by this can lock the threads in close contact with each other, and as a result, during transportation or when the container 1 is dropped, etc. Even in this case, the cap 2 can be kept in the tightened state.

On the other hand, the cap 2 attached to the container 1 can be removed by simply rotating the cap 2 counterclockwise, and the cap 2 can be smoothly rotated smoothly without resistance even with this removing operation. The narrow portions 61 are guided obliquely upward to the right along the thread 50, so that the cap 2 can be removed soon.

In this way, when the cap 2 is tightened, the tips of the narrow portions 61 on the side of the cap 2 come into contact with the convex portions 15 on the side of the container 1 and are stopped, so that the cap 2 cannot be tightened further. The screwing of the two screw portions 5, 6 is stopped by a predetermined amount, and therefore the tightening of the cap 2 does not become excessive. In this stopped state of screwing, as shown in FIG. 3, since a predetermined space S is maintained between the sheet body 3 and the cap 2, the back surface 23 of the cap 2 does not touch the sheet body 3. .. Therefore, the sheet body 3 is prevented from being further rotated not only when the cap 2 is tightened but also when the cap 2 is removed, and as a result, the sheet body can be prevented from twisting, and the appearance of the stored item 8 is impaired. Can be protected against Such an action does not require special attention when tightening and removing the cap 2, and can be performed easily and has excellent operability.

Further, at the time of this mounting, since the edge surface 24 of the cap 2 is separated from the shoulder portion 12 of the container 1, there is no possibility that the cap 2 becomes difficult to open due to the bite. Further, at this time, since the screwed state is tightly brought into close contact with each other by the compression between the thread 50 and the corresponding thread 60, the container 1 can be sealed and the hermeticity is improved. Is also excellent.

In addition, in the above-described embodiment, with respect to the corresponding thread 60, the side portion on the back surface 23 side in the thread end portion on the edge surface 24 side is formed narrower than the thread end by a predetermined length. However, as shown in FIG. 6, for example, the opposite side part, that is, the side part on the edge surface 24 side, may be formed to be narrower than the strip end. Even in the narrow portion 62 formed by being offset on the opposite side as described above, it is possible to perform light and smooth screwing similarly, and it is of course possible to obtain the same effect as that of the above embodiment. Further, regarding the corresponding thread 60, a vent portion 63 extending along the thread length direction is provided at a thread length portion to be fitted in the groove portion between the two thread threads 50, as shown in FIG. May be formed to improve dimensional absorbability. As a result, the frictional force can be stably and reliably obtained, and the stability of the locking / holding operation by the frictional force can be improved.

Further, the configurations of the female screw portion 5 and the male screw portion 6 are not limited to the so-called two-thread screw as in the above embodiment. For example, a triple thread screw or the like can be appropriately configured.
