[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container.

[0002]

[Prior art]

Conventionally, for example, a glass ampule is known as a container for storing a drink or the like. These are often used because they can store hygienic contents and can be filled mechanically, but they are made of glass, so they are easily broken, and there are problems such as damage at the cut when opening. is there.

[0003] The present invention has been made in view of the above points, the contents can be sealed and stored in a good condition, and can be easily opened, and the contents may be damaged when drinking after opening. The present invention proposes an excellent container without any.

[0004]

In order to solve the above-mentioned problems, the container of the present invention raises the mouth and neck 6 from the upper end of the cylindrical body 4 whose lower end is obstructed flat and closes the upper opening of the mouth and neck 6. The lower surface of the lid plate 7 on the mouth and neck through the thin-walled break portion 8
A container body 2 made of a synthetic resin integrally connected to the surface, and mounted on the outer periphery of the mouth and neck portion 6 from above, and a ridge 16 provided on the lower portion of the inner periphery of the peripheral wall 13 is attached to the outer periphery of the mouth and neck portion 6. Projected ridges at the bottom
10 engaged with the lower surface of a synthetic resin cap 3 which is attached to the mouth and neck 6 the outer periphery and the cap wall of the ridge above
A cam mechanism for raising the cap 3 relatively with the rotation of the cap 3 is provided on the inner periphery of the cap 13. At the upper part , a plurality of vertical ridges 17 engageable with the respective vertical ridges 12 are provided so as to protrude in the circumferential direction.

[0005]

When the cap 3 is rotated from the state shown in FIG. 1, the vertical ridges 12 of the lid plate 7 and the vertical ridges 17 of the cap 3 are engaged, and the lid plate 7 is twisted with respect to the mouth and neck 6. As a result, the breaking portion 8 breaks and opens. Next, the cam mechanism between the outer periphery of the mouth and neck 6 and the inner periphery of the cap 3 operates to raise the cap 3 with respect to the container body 2. Can be removed to remove the cap 3 and the cover plate 7.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a liquid container. The container 1 includes a container body 2 and a cap 3.

The container body 2 is formed of a synthetic resin, and is a squeezable tubular body 4 having a lower end flatly closed.
The mouth and neck 6 is erected from the upper end via the shoulder 5, and a top plate 7 for closing the upper opening of the mouth and neck 6 is integrally connected via a thin break 8.

The mouth and neck 6 includes a cylindrical base 6a at the lower end,
A reduced diameter portion 6b extending above the base portion 6a via an upwardly directed step portion 9
A cap ridge 10 is provided around the outer periphery of the base 6a, and an upwardly facing triangular plate-like projection 11 forming a part of a cam mechanism is provided on the upper surface of the step portion 9 in front and rear of the container body. ing.

The cap 3 is made of a synthetic resin and has a cylindrical shape with a lower end surface opening in which a top wall 14 is extended from an upper end edge of a peripheral wall 13.
13 The inner circumference of the lower part is enlarged through the downward step 15,
The ridge 16 is fitted over the mouth neck 6 of the container body from above, and the ridge 16 provided around the enlarged diameter portion of the inner peripheral lower portion of the peripheral wall 13 is forcibly climbed over the ridge 10 of the mouth neck 6 to lower the lower surface thereof. It is engaged and is attached to the container body 2 so that it cannot come out.

The inner peripheral upper end portion of the peripheral wall 13 is substantially 90 in the circumferential direction.
Four vertical ridges 17 protrude at intervals of °. Each vertical ridge 17
Is the vertical ridge 12 of the container when the cap 3 is fitted from above.
As shown in FIG. 3, the lower surface is formed in a downwardly triangular shape so that it can be pressed down without difficulty even if it comes into contact with the upper surface of each vertical ridge 12 of the container body 2 for the same reason. ing. Then, by rotating the cap 3 with respect to the container body 2, each of the vertical ridges 12 and 17 is engaged, and the cover plate 7 is forcibly rotated with respect to the container body neck 6 and the broken portion is formed. 8 can be cut.

A downward triangular plate-like projection 18 forming a part of the cam mechanism is provided on the lower surface of the downward step 15 on the left and right sides of the peripheral wall 13. Then, when the cap 3 is rotated with respect to the container body 2, each downward triangular plate-like projection 18 rides on each upward triangle plate-like projection 11 of the container body 2, and the cap 3 is moved to the container body 2.
, So that the engagement between the ridge 10 of the container body neck 6 and the ridge 16 of the cap 3 is released.

The above-mentioned vertical ridges 12 and 17, upward triangular plate-like projections 11
The positional relationship between the downwardly-facing triangular plate-like projections 18 will be described with reference to FIGS.

In FIG. 3, a central upward triangular plate-like projection is shown.
Assuming that 11 is located at the front part of the container body, a vertical ridge 12 is located at the same upper position, and furthermore, vertical ridges 12 are provided on the left and right at approximately 90 ° intervals. On the other hand, the vertical protruding strips 17 are configured so as to be located at positions shifted from each other by approximately 45 ° with respect to the downward triangular plate-shaped projections 18, respectively. When the cap 3 is mounted, as shown in FIG. Approximately 45 with vertical ridge 17
The triangular plate-like projections 11 and 17 each have an angle of about 9 °, as shown in FIG.
They can be located at 0 ° intervals. Therefore,
Since there is a sufficient space between each of the vertical protrusions and each of the triangular plate-shaped protrusions, there is no inconvenience that the break portion 8 is broken by mistake when the cap is attached.

In the figure, reference numeral 19 denotes a suction pipe.

FIG. 5 shows another embodiment of the present invention.
In the present embodiment, the top wall of the cap 3 is eliminated, and the engagement state of each of the vertical ridges 12, 17 can be observed from above, so that the user can recognize whether the seal has been opened. The rest of the configuration is the same as in the above embodiment.

[0017]

[Effect of the Invention] As described above, the container of the present invention has the above-described structure, so that the thin-walled portion can be automatically cut and opened by an extremely simple operation of rotating the cap. Can be automatically released and the cap can be easily removed.

In addition, when filling the contents, the liquid can be injected from the lower end of the body of the container and immediately closed, so that the contents can be stored in a closed state.

Further, since both the container and the cap are made of synthetic resin, there is no risk of breakage as in a conventional ampule, and there is no risk of damaging a hand or the like at the opening after the lid is opened.
