Description

[Detailed description of the invention] "Field of industrial application" The present invention relates to a container with a cap, and more specifically, to a container with a cap configured so that the cap can be attached to and removed from the container body etc. by a simple rotation operation. It is.

"Problems to be Solved by Conventional Technologies and Ideas" Conventionally, the most common container with a cap consists of a container body with an upright neck and a peripheral wall screwed onto the outer periphery of the mouth and neck. One example is one consisting of a cap with an extended wall. In these cases, the cap must be rotated many times when it is attached or detached, which takes time and is troublesome to handle.

In addition, a protrusion is provided around the lower outer periphery of the container mouth neck, and a protrusion is also provided below the inner periphery of the cap peripheral wall, so that the protrusion of the cap is fitted over the protrusion of the container body. Various configurations are also used. These caps are attached by pushing the cap down from the upper part of the mouth and neck, and removed by pulling it up. Although it does not take long to attach or detach, it requires a large amount of force to remove the cap by pulling it up, and the container body vibrates during this process, causing the contents to be removed. This may cause the inconvenience of the liquid flowing out inadvertently.

In consideration of these points, a container has been proposed in which an end cam mechanism is provided which pushes the cap upward as the cap rotates in the horizontal direction, so that the lower end surface of the cap circumferential wall is connected to the upper surface of the shoulder of the container body. These cam mechanisms have been proposed, for example, in which an undulating surface having an upwardly raised protrusion is provided around the shoulder of the container body, and the lower end surface of the cap peripheral wall is configured in the same shape as the undulating surface. Therefore, the cap can be attached and detached more easily than the above-mentioned containers.

However, when installing the cap, if the installation position is misaligned, it is difficult to fit the cap into the correct position unless you slide the lower end of the cap peripheral wall onto the undulating surface and push the cap in while twisting. There was room for improvement in this respect.

On the other hand, a cylindrical wall is provided at the center of the upper part of the container body, and a V-shaped restraining groove for positioning is provided at the symmetrical part of the front and back center of the top surface of the cylindrical wall, and an arc-shaped guide groove continuous with the said restraining groove is provided at both symmetrical parts. There has also been proposed a container having an end face cam mechanism in which a rib-shaped key is formed on the inner surface of the cap. However, with this container, the key is located in an invisible position on the inside surface of the cap, making it difficult to align the key with the V-shaped restraining groove when installing the cap, and if the key is misaligned. In this case, it is difficult to fit the cap into the proper position unless you twist and push the cap so that the lower end of the key slides into the arc-shaped guide groove. It was hot.

If the cap is not installed in the proper position, problems such as leakage of liquid from the spout hole and deformation of the lower end surface of the peripheral wall of the cap may occur, which is undesirable.

The present invention proposes a container with a cap that eliminates the drawbacks of the prior art described above.

"Means for Solving the Problems" In order to solve the above problems, the container of the present invention has two body parts.
A container body 1 has a neck part 4 erected from the upper end via a shoulder part 3, and a lower end surface of a peripheral wall 6 is placed on the upper surface of the outer peripheral part of the shoulder part, and elasticity is fitted to the outer surface of the upper part of the container body. The cap 5 is made of a synthetic resin rich in water, and an end cam mechanism is provided between the lower end surface of the cap circumferential wall 6 and the upper surface of the shoulder of the container body to push the cap 5 upward as the cap 5 rotates in the horizontal direction. In this container with a cap, a plurality of guide holes 7 are formed in the cap peripheral wall 6, and the inner circumferential surface thereof has a tapered inclined surface that becomes wider as it goes inward. A guide protrusion 9 to be accommodated and fitted is configured to protrude from the outer surface of the mouth and neck part 4.

"Operation" When the cap is twisted horizontally, the guide protrusion 9
The tapered inclined surface of the guide hole 7 allows the guide hole 7 to easily separate from the guide protrusion 9, and the end cam mechanism also allows the cap to be easily pushed upwards into a free state. Become.

On the other hand, when attaching the cap to the container body, using each guide protrusion 9 as a mark, guide the through hole 7 to the protrusion 9.
When the cap is fitted onto the outer surface of the upper part of the container body from above, each guide hole 7 is fitted into each guide protrusion 9, and the lower surface of the cap circumferential wall is placed in a predetermined position on the upper surface of the shoulder part of the container body. Fit together. On this occasion,
Even if there is a slight deviation in the fitting position of the cap, the elastic restoring force of the circumferential wall of the cap expanded by the guide protrusion 9 will automatically fit each guide through hole 7 into each guide protrusion 9. Then, the lower end surface of the cap circumferential wall is automatically fitted into a predetermined position on the upper surface of the shoulder of the container body.

``Embodiment'' As shown in the accompanying drawings, the container with a cap according to the present invention includes a container body 1 having a neck portion 4 erected from the upper end of a body portion 2 via a shoulder portion 3, and an upper surface of the outer peripheral portion of the shoulder portion. and a highly elastic synthetic resin cap 5 on which the lower end surface of the peripheral wall 6 is placed and fitted onto the outer surface of the upper part of the container body.

Then, a cylindrical attachment member 8 that is unrotatably fitted to the outer surface of the cylindrical part forming the mouth and neck part or to the mouth and neck part.
A plurality of guide protrusions 9 project from the outer surface of the cylindrical portion at approximately equal intervals, and the outer peripheral surface of each of these protrusions is formed into a guide through hole 7 formed in the cap peripheral wall.
By twisting the cap in the direction of rotation with respect to the container body, the circumferential wall of the cap is elastically deformed, and the deformation causes the guide protrusion to be removably fitted into the guide hole.

In the container with a cap according to the present invention, the container body 1 and the cap 5 are formed in a cylindrical shape in each of the embodiments shown in FIGS.
It may be formed into a rectangular tube shape as in the embodiment shown in the figure. Further, in each of the embodiments shown in FIGS. 1 to 3, the cap 5 and the like are particularly formed of an elliptical cylinder, and one guide hole 7 is bored in each of the peripheral wall portions facing each other in the short axis direction. . According to this, by rotating the cap by applying force to the circumferential wall portion in the longitudinal direction, there is an advantage that the rotational force can be much smaller than when the cap is a true cylinder.

In the embodiment shown in FIGS. 1 to 3, the lower end surface of the cap peripheral wall 6 and the outer peripheral upper surface 3a of the container body shoulder 3 are
are in contact with gently uneven surfaces that are symmetrical in the short axis direction and the long axis direction, respectively, and when the cap is rotated, the cap is moved against the container body by the end face cam mechanism consisting of the above uneven surfaces. It has risen slightly, making it easier to remove it. In the embodiment shown in FIG. 4 based on a similar technical idea, the container body shoulder 3 is raised in the shape of a mountain along the diagonal at the corner.

In the embodiment shown in FIGS. 1 and 4, the guide protrusion 9 is provided to protrude directly from the outer surface of the container mouth neck 4, but as in the embodiment shown in FIGS. 2 and 3, It may be provided protrudingly on the outer surface of the cylindrical mounting member 8 fitted to the mouth and neck. 10a and 10b in Figure 2A
are an engagement groove and an engagement protrusion vertically provided on the inner surface of the cylindrical mounting member 8 and the outer surface of the mouth and neck part, respectively, for rotation prevention purposes.

Further, the inner circumferential surface of the guide hole 7 is formed into a tapered slope that widens as it goes inward, and the outer circumferential surface of the guide protrusion 9 is formed as a tapered slope that narrows as it goes outward. , when the caps are rotated, they can be easily separated from each other with a small amount of force.

Furthermore, the guide protrusion 9 and the guide through hole 7
is formed into an elliptical shape in the embodiment shown in FIGS. 1 to 3, but it may be formed into a heart shape as in the embodiment shown in FIG. 4, or may have another shape.

In the embodiment shown in FIGS. 1 and 2, a nozzle member 11 is fitted to the upper end of the container mouth neck 4, and a cap 5 is inserted into the nozzle hole 11a of this nozzle member 11.
A cylindrical stopper 12 hanging down from the top wall is removably fitted therein.

``Effects of the invention'' As explained above, according to the invention, the above-described structure allows the cap to be attached and detached from the container body etc. by a simple rotation operation, and the attachment and detachment of the cap does not require much force. The effect is that it can be done quickly. Further, the attachment position of the cap to the container body can always be kept at an accurate position.
Furthermore, once the cap is fitted to a certain position, the through-hole guide will automatically fit into the protrusion due to the elastic restoring force of the peripheral wall of the cap bulged by the guide protrusion, and as a result, the cap will be placed in its proper position. mating can be done automatically.
