Abstract

PURPOSE:To provide a container cap which does not be broken when turned in the reverse direction and which obviates a mold of high dimensional precision by separating its elastic part from a stopper and providing the stopper with a sufficient strength. CONSTITUTION:A neck 4 of a container 1 has threads 4a on the outer periphery and raised part 5 at the neck under the threads. A vertical internal cylinder 8 vertically suspending from a ceiling plate 6 of a cap 2 has threads 8a to be engaged with the threads 4a. An elastic part 10 and stopper 9 are provided vertically, extending beyond the bottom of the internal cylinder 8. The gap in the circumferential direction between the elastic part 10 and stopper 9 is approximately equalized to the size of the raised part 5. Thus, when the cap 2 is closed, the bottom end 10c of the elastic part 10 goes beyond the raised part 5 and the bottom end 9a of the stopper 9 contacts the raised part 5, thereby stopping the cap turn.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with a cap having a positioning function.

[0002]

2. Description of the Related Art In general, a tubular container for containing a liquid such as shampoo has a substantially oval shape with shoulders protruding to the left and right, and a container body having a cylindrical neck portion standing on the shoulders. The container is provided with a substantially oval-shaped cap projecting to the left and right, and the cap is attached to the neck portion of the container body. Some of such containers are provided with a positioning mechanism so that the cap is placed on the shoulder portion of the container body while overlapping with each other in the closed state. As a container with a cap of this type, a container disclosed in Japanese Utility Model Publication No. 61-43712 is disclosed. In this container, for example, as shown in FIGS. 18 and 19, a male screw 32a is provided on the outer periphery of the mouth / neck portion 32 of the container body 31, and the male screw 32a is provided.
A pair of left and right locking protrusions 33 are formed outwardly at the lower end of the skirt wall 35 that hangs from the peripheral edge of the top wall 34a of the cap 34, and a cylindrical wall that hangs from the center of the top wall 34a. On the inner circumference of this cylindrical wall, a female screw 36a screwed with the male screw 32a is provided) 36,
A pair of left and right hanging pieces 37 that engage with the locking protrusions 33 are provided, and the hanging pieces 37 are formed in a U-shaped cross-sectional shape consisting of a short side 37a, a connecting side 37b, and a long side 37c. Then, when the lid is closed, the female screw 36a of the cylindrical wall 36 of the cap 34 is screwed onto the male screw 32a of the mouth / neck portion 32 of the container body 31, and then tightened. As a result, at the end of tightening, the U-shaped short side 37a of the hanging piece 37 rides over the locking projection 33, and this locking projection 33 engages in the U-shape of the hanging piece 37 to allow the cap 34 to move. The rotation is stopped and the cap 34 is positioned at a specific position.

[0003]

However, in this one, since the hanging piece 37 hanging from the top wall 34a of the cap 34 is caused to perform the spring action, the long side 37c of the U-shape has elasticity (spring). Function), and the thickness cannot be made too thick. Therefore, the strength of the long side 37c cannot be increased so much, and when a large load is applied to the long side 37c by accidentally rotating the cap 34 in the opposite direction when the lid is opened, the length of the long side 37c is increased. The side 37c is damaged. Moreover, since the hanging piece 37 is formed in a U-shape, and since an appropriate gap must be provided between the tip end portion of the U-shaped short side 37a of the hanging piece 37 and the outer circumference of the cylindrical wall 36, A mold for molding the cap 34 is required to have high dimensional accuracy.

The present invention has been made in view of such circumstances, and even if the cap is rotated in the opposite direction when the lid is opened, the cap will not be damaged, and high dimensional accuracy of the mold is not required. The purpose is to provide a container with a cap.

[0005]

To achieve the above object, a container with a cap according to the present invention comprises a container body having a neck portion and a cap attached to the neck portion of the container body. Provide a screw part on the outer peripheral surface,
An engaging projection is provided in a portion below the threaded portion, a tubular body is hung from the lower surface of the ceiling plate of the cap, and a threaded portion that engages with the threaded portion is provided on the inner peripheral surface of the tubular body. Provided, the elastic body portion and the stopper portion are hung from the outer peripheral portion of the tubular body so as to extend beyond the lower end of the tubular body, and the circumferential distance between the elastic body portion and the stopper portion is set to the engagement projection portion. Approximately according to the dimensions, when the cap is rotated with the lid closed, the free end portion of the lower end of the elastic body rides over the engaging projection, and the lower end of the stopper portion abuts on the engaging projection to prevent rotation. The configuration is as follows.

[0006]

That is, in the container with a cap of the present invention, the engaging projection is provided at a portion below the threaded portion provided on the outer peripheral surface of the neck of the container main body, and is hung from the lower surface of the ceiling plate of the cap. An elastic body portion and a stopper portion are hung from the outer peripheral portion of the tubular body (the inner peripheral surface of which has a threaded portion that engages with the threaded portion) so as to extend beyond the lower end of the tubular body. The circumferential distance between the elastic body portion and the stopper portion is approximately matched with the size of the engaging projection. When the lid is closed, the threaded portion of the tubular body of the cap is screwed into the threaded portion of the neck portion of the container body, and then the lid body is rotated in the lid closing direction. As a result, at the end of the cap closing rotation of the cap, the free end portion of the lower end of the elastic body rides over the engaging projection, and the lower end of the stopper portion abuts the engaging projection. The portion is engaged between the stopper and the elastic body portion to prevent the cap from rotating. On the other hand, when opening the lid, the cap in the closed state is rotated in the opening direction. As a result, the free end portion of the lower end of the elastic body portion gets over the engagement projection and disengages from the engagement projection, and the lid is opened when the rotation is continued. As described above, in the container with a cap of the present invention, the stopper portion only abuts against the engaging projection to prevent rotation, and does not act as a spring, so that the thickness can be increased. Therefore, the stopper portion can be provided with sufficient strength, and the stopper portion will not be damaged even when a large load is applied to the stopper portion by accidentally rotating the cap in the opposite direction when opening the lid. . In addition, in the container with a cap of the present invention, the elastic body portion and the stopper portion are formed as separate bodies, and each of them is only hung vertically from the outer peripheral portion of the tubular body. The mold is not required to have high dimensional accuracy, and the cost of the mold is low.

Next, the present invention will be described in detail based on embodiments.

The lower side has a large diameter on the side and the lower side has a small diameter on the upper side. Engaging projections 5 are formed on the left and right sides of the step on the lower side.

As shown in FIG. 1, the cap 2 includes a ceiling plate 6 and an outer cylinder 7 vertically extending from the outer peripheral edge of the ceiling plate 6.
And an inner cylinder (cylindrical body) 8 suspended from the central portion of the ceiling plate 6, and on the inner peripheral surface of the inner cylinder 8 to the screw portion 4a of the neck portion 4 of the container body 1. A threaded portion 8a is formed so as to mate with each other. Further, as shown in FIG. 7, the inner cylinder 8 is formed with a pair of stopper portions 9 and elastic body portions 10 on the left and right sides of the outer peripheral surface thereof. As shown in FIGS. 8 to 10, the stopper portions 9 are each formed of a vertically long flat plate-like body, and have an upper end edge of the inner cylinder 8 (that is, the ceiling plate 6).
(The lower surface of the inner cylinder 8) and the lower end edge 8b of the inner cylinder 8 along the axial center of the inner cylinder 8 so as to project integrally with the outer peripheral surface of the inner cylinder 8 and to lower the lower end edge 8b of the inner cylinder 8. This lower end portion (a portion below the lower end edge 8b of the inner cylinder 8) 9 extends beyond and extends downward.
a is slightly inside the outer peripheral surface of the inner cylinder 8. The lower end portion 9a of the stopper portion 9 comes into contact with the engaging protrusion 5 provided on the neck portion 4 of the container body 1 in a rotation preventing manner.

Further, in both of the elastic body portions 10, a vertically elongated ridge 10a integrally formed on the outer peripheral surface of the inner cylinder 8 and an inner side surface are formed in an arc shape, and a central portion of the arc shape portion is formed. It is composed of a substantially semicircular portion 10b connected to the protrusion 10a, and the protrusion 10a hangs along the axial center of the inner cylinder 8 between the upper end edge and the lower end edge of the inner cylinder 8. Further, the substantially semicircular portion 10b hangs along the axial center of the inner cylinder 8 between the upper end edge and the lower end edge 8b of the inner cylinder 8 together with the protrusion 10a, and the lower end edge 8b of the inner cylinder 8 is The lower end portion (a portion below the lower end edge 8b of the inner cylinder 8) 10c extends over and extends downward so that the lower end portion 10c can ride over the engagement projection 5 and freely come into contact therewith. That is, when the cap 2 is rotated in the closing direction after this contact, the lower end portion 10c is elastically deformed outward so as to be able to get over the engaging projection 5. The distance between the stopper portion 9 and the elastic body portion 10 is set to be slightly shorter than the circumferential length of the engaging projection 5 of the neck portion 4, whereby the arc-shaped inner portion of the elastic body portion 10 is formed. The engagement protrusion 5 can be engaged between the stopper portion 9 and the elastic body portion 10 in a state in which the engagement protrusion 5 is pressed by the side surface. In FIG. 9, 6a
Is an inner annular body projectingly formed on the lower surface of the ceiling plate 6 of the cap 2, and 6b is an outer annular body.

An inner lid 11 is attached to the neck portion 4 of the container body 2. As shown in FIG. 11, the inner lid 11 has a ceiling plate 1 in which a circular hole 12a for liquid circulation is formed in the center.

And an inner cylinder 14 suspended from the central portion of the ceiling plate 12, and the container body 1 is provided at the lower end of the inner peripheral surface of the outer cylinder 13.
A ring-shaped engaged portion 13a that can be detachably engaged with the engaging portion 4b of the neck portion 4 is projectingly formed, and the cap 2 at the outer peripheral portion of the round hole 12a on the upper surface of the ceiling plate 12 when the lid is closed. 12b that is in liquid-tight contact with the lower end of the inner annular body 6a
Are formed to project. Further, when the lid is closed, the outer peripheral portion of the upper surface of the ceiling plate 6 is in liquid-tight contact with the lower end portion of the outer annular body 6b of the cap 2.

In the above structure, when the lid is closed, the threaded portion 4a of the neck 4 of the container body 1 is engaged with the threaded portion a of the inner cylinder 8 of the cap 2, and the cap 2 is rotated in the closing direction. Is done. As a result, as shown in FIGS. 12 and 13, at the end of the closing rotation of the cap 2, the lower end portion 10 c of the elastic body portion 10 of the cap 2 causes the neck portion 4 of the container body 1 to move.
14 to 16, as shown in FIGS. 14 to 16, the lower end portion 10c elastically deforms to get over the engaging projection 5 and, as shown in FIG. The lower end 9a of the stopper portion 9 comes into contact with the engaging projection 5 at substantially the same time as the vehicle gets over, and is prevented from rotating. On the other hand, when opening the lid, the cap 2 in the closed state is rotated in the opening direction. As a result, the lid is opened in the reverse order of the above operation.

As described above, in the above-described embodiment, since the stopper portion 9 does not act as a spring, the stopper portion 9 can be formed thicker by that amount and can be made stronger. Therefore, even when a large load is applied to the stopper portion 9 by accidentally rotating the cap 2 in the opposite direction when opening the lid,
It will not be damaged. Moreover, since the elastic body portion 10 and the stopper portion 9 are formed separately, and only each is integrally formed on the outer peripheral surface of the inner cylinder 8, the dimensional accuracy of the elastic body portion 10 and the stopper portion 9 is high. Does not need to be high, and the mold for molding the cap 2 is not required to have high dimensional accuracy. Moreover, since the stopper portion 9 and the elastic body portion 10 are formed from the upper end edge to the lower end edge 8b of the outer peripheral surface of the inner cylinder 8, the area integrally formed with the inner cylinder 8 is large and the stopper portion 9 and The lower end 9a of the elastic body portion 10,
Even when a considerably large load is applied to 10c or the like, they are not damaged.

In the above embodiment, the engaging projection 5 is formed so as to project from the neck portion 4 of the container body 1. However, the present invention is not limited to this, and the upper surface of the shoulder portion of the body portion 3 of the container body 1 is not limited to this. You may make it form a protrusion.

Further, in the above embodiment, the interval between the stopper portion 9 and the elastic body portion 10 is set to be slightly shorter than the circumferential length of the engaging projection 5 of the container body 1, but it is not limited to this. However, the length may be set to be the same as the circumferential length of the engaging projection 5, or may be set to be slightly longer.

[0016]

As described above, according to the container with a cap of the present invention, the stopper portion only comes into contact with the engaging projection to prevent rotation, and does not act as a spring, so that the thickness is reduced accordingly. It can be formed thick. Therefore, the stopper portion can be provided with sufficient strength, and the stopper portion will not be damaged even when a large load is applied to the stopper portion by accidentally rotating the cap in the opposite direction when opening the lid. . In addition, in the container with a cap of the present invention, the elastic body portion and the stopper portion are formed as separate bodies, and each of them is only hung vertically from the outer peripheral portion of the tubular body.
