[0002]

2. Description of the Related Art As a liquid discharge container, for example, a top wall is extended from an upper end edge of a peripheral wall screwed to the outer periphery of a neck portion of a container body, and an upper end closed nozzle having a lower end opened at the center of the top wall is integrally formed. 2. Description of the Related Art There is known an apparatus equipped with a cap with a nozzle that is provided upright. These are used by cutting and removing the nozzle tip at the time of use.

In addition, a top wall is extended from an upper end edge of a peripheral wall screwed to an outer periphery of a neck portion of a container body, and a pouring cylinder is erected from a central portion of the top wall, and a rod stopper is supported in the center of the pouring cylinder. A peripheral wall is fitted to the outer periphery of the spout cylinder so as to be able to move up and down, and the lower edge of the inner periphery of the spout hole formed at the center of the top wall is liquid-tightly contacted with the upper surface periphery of the plug. There is known one provided with a nozzle in contact therewith. These can be dispensed simply by pulling up the nozzle, and if the nozzle is pushed down again, it will return to the closed state of the spout hole, so it is convenient to carry, especially when used as a container for drinking water It is.

[0004]

In these containers, the size of the spout hole is always constant, and therefore, the amount of spout per unit time is also limited to a substantially constant amount. In addition, since the lower edge of the inner periphery of the spouting hole and the upper edge of the top of the plug are generally made of relatively rigid synthetic resin, the nozzle may slightly move upward due to impact when the container is accidentally knocked down. There is a possibility that the contact surface may be opened, and in that case, there is a possibility that leakage of the liquid may occur.

[0005] Further, it is required to clearly indicate that these containers are unopened at the time of sale or the like, and in particular in the case of a beverage container in which the stored liquid is drinking water. Therefore, conventionally, for example, shrink wrapping that can be easily broken is performed on a cap portion. However, shrink wrapping has the problem of requiring large-scale equipment for that purpose.

In view of the above, in the present invention, it is possible to change the dispensing amount by a simple operation, and the closed portion of the dispensing hole does not easily open due to impact or the like, and the container is erroneously inserted. There is no danger of liquid leakage even if it is overturned, and it can be manufactured without the need for special large-scale equipment such as shrink packaging,
Moreover, the present invention proposes an excellent container which is convenient to carry and is easy to use.

The liquid discharge container according to claim 1 is configured to be engaged.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. The liquid dispensing container 1 of the present invention includes a container A, a cap body B, a lid C, and an elastic wall D.

The container body A is made of a synthetic resin or the like, and has a mouth and neck 3 standing upright from the upper end of a cylindrical body 2. It is also possible to make the body 2 squeezable.

The cap body B is fitted into the container body neck portion 3 in a liquid-tight manner so that it cannot be pulled out, cannot rotate, and extends from the top edge of the peripheral wall 4 fitted around the mouth neck portion 3. At the same time, a lower end of the top wall 5 is communicated with the lower end thereof to communicate with the lower end thereof, and the pouring cylinder 6 is erected upward.

In order to fit the cap body B to the container body A so that it cannot rotate and cannot come out, the inner periphery of the peripheral wall 4 may be closely fitted to the outer periphery of the mouth and neck portion 3. As described above, between the outer peripheral upper part of the mouth and neck part 3 and the inner peripheral upper part of the peripheral wall 4, there is provided an engaging means 8 comprising a vertical ridge and a vertical concave groove or a vertical ridge and a vertical ridge to prevent rotation. In addition, the engaging ridges 10 that extend over and engage with the lower surfaces of the engaging ridges 9 provided on the outer peripheral lower part of the mouth and neck part 3 are provided on the inner peripheral lower part of the peripheral wall 4 to prevent slipping out. In this case, rotation and escape can be more reliably prevented.

In order to fit the cap body B to the mouth and neck portion 3 in a liquid-tight manner, a packing may be interposed between the upper surface of the mouth and neck portion 3 and the back surface of the top wall 5, but as shown in FIG. A seal tube 11 hanging from the peripheral edge of the back surface of the top wall 5 may be fitted to the upper end of the inner surface of the mouth and neck portion 3 to prevent leakage of liquid from this portion.

The dispensing cylinder 6 is for dispensing the liquid in the container body. In the illustrated example, the dispensing cylinder 6 has a cylindrical shape standing upright at a central portion having a small width from the outer peripheral edge of the upper surface of the top wall 5. The outer peripheral upper end is curved to form a curved portion a, so that the elastic wall D can be more easily slid, and the elastic wall D is prevented from being damaged.

The column 7 is for fitting a window hole in the center of the elastic wall D, which will be described later, to the upper end portion of the outer periphery thereof to hermetically seal it. In the illustrated example, the top wall 5 in the pouring cylinder has a columnar shape standing upright from the center of the upper surface, and an annular concave portion b for fitting a window hole of the elastic wall D is formed in the periphery of the upper surface. In addition, prop 7
A plurality of communication holes 12 are formed in the top wall 5 in the outer pouring cylinder 6 to communicate between the mouth and neck 3 and the pouring cylinder 6. In the present embodiment, the column 7 is erected from the center of the upper surface of the top wall 5 of the cap body. However, the column 7 is supported in the pouring tube 6 via radial connecting ribs protruding from the outer periphery. You may. In that case, it is preferable to omit the top wall in the pouring cylinder.

The lid C has a top wall 14 extending from an upper edge of a peripheral wall 13 screwed to a position where the cap body peripheral wall 4 can be screwed down on the outer peripheral upper part thereof. An annular break portion d is provided at the position. Then, when the lid C is screwed down, the annular breaking portion d is broken and the top wall 14 of the inner portion is separated, and the pouring cylinder 6 is configured to protrude above the top wall 14 of the lid. .

In addition, the lower surface of the lid peripheral wall 13 is integrally connected to the lower surface of the lid main body 4 via a break portion e, and the lower surface is abutted and locked on the upper surface of the engaging ridge 15 provided on the outer peripheral lower portion of the cap main body peripheral wall 4. A ring-shaped spacer E may be provided. The broken portion e in the illustrated example is formed by a large number of thin rod-shaped connecting pieces that connect the upper surface of the spacer E and the lower surface of the lid peripheral wall 13 with a circumferential interval.
17 is comprised. In the illustrated example, the cover peripheral wall 13
The engagement ridge 18 protruding from the lower edge of the inner periphery rides over and engages the lower surface of the engagement ridge 19 of the cap body B to prevent it from slipping upward, and to be screwed with the thread of the cap body. Is provided at the center in the vertical direction on the inner periphery of the lid peripheral wall 13.

The elastic wall D closes the upper end opening of the pouring cylinder 6 and changes the size of the window hole f formed in the center thereof as the lid peripheral wall 13 is screwed down. It is made of a material that is stretchable and strong in expansion and contraction resistance, such as an elastomer, and has an outer peripheral edge fitted and fixed to the inner peripheral upper end of the lid peripheral wall 13, and the upper opening of the pouring cylinder 6 is closed. The center window f of the lever is fitted to the peripheral edge of the upper end of the column 7.

Then, when the lid C is screwed down, the peripheral portion is pulled and the central window hole f is enlarged, so that a ring-shaped pouring hole f1 is opened around the upper end of the column 7. The size of the pouring hole f1 changes depending on the degree of the screw body C's downward descent.

In the illustrated example, an engagement ridge 21 sandwiched between an engagement ridge 20 protruding from the rear edge of the lid top wall 14 and a peripheral edge of the lid 13 is formed in an annular shape with a projection on the upper edge. The base 22 is attached to the lid peripheral wall 13
It is fitted and fixed to the upper end of the inner surface, extends from the inner peripheral edge of the upper surface of the annular base along the upper end of the outer surface of the pouring cylinder 6, closes the upper opening of the pouring cylinder 6, and fits the central window hole f into the annular concave portion b. An elastic wall D of a combined thin plate is extended.

When the container 1 is used, for example,
After removing the spacer E from the state of FIG. 1 and removing the spacer E, when the lid C is screwed down, the annular fractured part d is cut and the inner top wall 14 is separated and poured out. Tube 6 is top wall 14
Project to the center. At this time, the outer peripheral edge of the elastic wall D is pulled downward, the central window hole f widens, and the pouring hole f1 opens around the column 7. The size of the pouring hole f1 differs depending on the screw-down state of the lid peripheral wall 13. For example, as shown in FIG. 2, when the screw-down is halfway, the pouring hole f1 is small, and as shown in FIG. When the screw down is in the lowest state, the pouring hole f1 is largely opened.

After use, if the lid C is screwed up again, the pouring hole f1 shrinks, and when it rises to a predetermined position, the window hole f fits into the annular concave portion b at the upper end of the column 7 and the pouring cylinder. 6 Close the upper end opening. Each of the above members can be formed of a synthetic resin.

[0024]

As described above, the container according to the present invention can be opened by a simple operation of screwing down the lid by using the above-mentioned structure, and furthermore, the container can be opened depending on the lowered state of the lid. Since the opening area of the outlet can be changed, it has the advantage of easily changing the amount of pouring per unit time.

Further, since the window hole formed in the elastic wall which can be extended and contracted is closely fitted to the peripheral edge of the upper end of the column, it is difficult for a gap to be formed in the sealed portion due to the impact, and the liquid leaks when the container is accidentally dropped. Is very unlikely to occur.

Furthermore, the unopened state can be indicated without requiring equipment such as shrink wrapping. In the case of the one provided with the spacer, the opening can be prevented from being unfairly performed, and at the time of opening, the spacer can be removed simply by pulling on one end, so that the handling is convenient.

Further, in the case where the peripheral wall of the lid and the peripheral wall of the cap body are configured so as not to be able to come out by the engagement of the engaging ridges, the window of the elastic wall is closed and the peripheral wall of the lid is further extended. The escape can be prevented, and the inconvenience that the elastic wall is unnecessarily raised and the window hole is opened when not in use is reliably prevented.
