Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite liquid discharging cap capable of dispensing a liquid in a container, and more particularly, to a liquid discharging cap (first liquid discharging cap) capable of discharging a liquid in a container as usual. ) And a liquid discharging cap (second liquid discharging cap) capable of dispensing the liquid in the container.

  Generally, seasonings such as dressings, sauces, soy sauce or edible oil are sold in a plastic container, and an opening is formed in a predetermined portion of a cap attached to the mouth of the container by tearing a score or the like. Then, with the cap attached, the container is tilted and discharged from the opening to be used for cooking or the like.

In the above-mentioned liquid contents, a relatively large amount of the liquid contents may be used, or a small amount of the liquid contents may be used depending on the amount of food to be cooked.
Therefore, there is a demand for a cap having a structure capable of changing the form of discharging the content liquid from the container.

The composite cap includes a first hinge cap hinged to a cap body attached to the container mouth, and a second hinge cap hinged to the first hinge cap. The cap body is provided with an opening for discharging liquid, and the first hinge cap is provided with a guide cylinder having an opening for discharging liquid. When the first hinge cap is closed, The guide cylinder is positioned so as to cover the liquid discharge opening of the cap body.
That is, when the first hinge cap is opened while the second hinge cap is covered and the container is tilted, the content liquid is discharged from the liquid outlet of the cap body, while the first hinge cap is closed. When the second hinge cap is opened and the container is tilted with the container closed, the contents can be dispensed from the guide cylinder provided on the first hinge cap.

  As understood from the above description, the conventionally known composite cap is capable of discharging the same liquid as usual and discharging a smaller amount of liquid than usual (dispensing). Since the diameter of the opening is merely changed, even when dispensing the content liquid, the amount of liquid discharged varies depending on the time the user tilts the container. The amount of liquid varies.

In the composite liquid discharging cap of the present invention, the first liquid discharging cap attached to the mouth of the container has a structure in which the second liquid discharging cap is further mounted. By discharging the content liquid through the communication hole of the first liquid discharging cap with the cap opened, the content liquid can be discharged as in the case of using a normal cap. The upper lid is opened in a state where is attached to the container mouth and the second liquid discharging cap is closed, and the content liquid can be dispensed in a constant amount by discharging from the second liquid discharging cap.
That is, in the present invention, the dispensing of the content liquid is performed after the content liquid is once transferred to the liquid reservoir provided on the first liquid discharging cap by inverting the container. One end (lower end) of the liquid dispensing pipe is located in the liquid reservoir, and the liquid contained in the liquid reservoir is discharged from the liquid dispensing pipe. . As will be understood from this, in the dispensing of the content liquid from the second liquid discharging cap (liquid dispensing pipe), only the content liquid contained in the liquid reservoir is discharged. Therefore, in the present invention, a constant amount of the liquid content is always dispensed, and the trouble of a general user performing the liquid dispensing while considering the discharge time (time to tilt the container) when dispensing is completely eliminated. Have been.

FIG. 8 is a diagram showing a side surface of the cap together with a container opening when dispensing the content liquid in a state where the content liquid is accommodated in the liquid reservoir shown in FIG. 7. FIG. 3 is a side cross-sectional view showing a preferable cross-section of the composite liquid discharging cap of the present invention together with a container mouth, and an enlarged front side view of a main part.

  With reference to FIGS. 1 to 5 showing the structure of a typical form of the composite liquid discharging cap of the present invention, the composite liquid discharging cap discharges the container content liquid while being attached to the mouth portion 100 of the container. A first liquid discharging cap 1 and a second liquid discharging cap 3 attached to the first liquid discharging cap for discharging a fixed amount of the content liquid into a small amount. An upper lid 5 is usually attached to the liquid discharging cap 3.

  In the composite liquid discharging cap of the present invention, the first liquid discharging cap 1 is provided so as to close the upper end of the cylindrical side wall 7 engaged with and fixed to the mouth portion 100 of the container. The second liquid discharging cap 3 is hinged to the peripheral edge of the top plate 9 or the upper end of the cylindrical side wall 7 by a first hinge band 11 so as to be openable and closable (see FIG. 1). 3 to 5).

An inner ring 13 is provided on the lower surface of the top plate 9 of the first liquid discharging cap 1 at a distance from the cylindrical side wall 7, and the inner ring 13 is provided between the inner ring 13 and the cylindrical side wall 7. The container mouth part 100 is fitted in the space.
An undercut 15 is formed at the lower end of the inner surface of the cylindrical side wall 7, and the undercut 15 engages with a jaw 103 formed above the support ring 101 of the container opening 100. Accordingly, the first liquid discharging cap 1 is firmly fixed to the container opening 100.

Further, as can be understood from FIG. 1, a slit 17 extending downward from the upper end is formed in the cylindrical side wall 7, so that the cylindrical side wall 7 is connected to the outer side wall 7a and the inner side wall 7b. The outer wall 7a and the inner wall 7b are connected at the lower end. As shown in FIGS. 4 and 5, the slit 17 is formed so as to penetrate from the upper end to the lower end of the cylindrical side wall 7 on the side where the first hinge band 11 is formed. At this portion, the cylindrical side wall 7 is completely divided into an outer side wall 7a and an inner side wall 7b.
That is, by forming the cylindrical side wall 7 into the double wall structure of the outer side wall 7a and the inner side wall 7b by the slit 17 as described above, the first liquid discharging cap 1 can be easily formed without using a special tool. The composite liquid discharging cap can be separated from the container and discarded. For example, by forming a score extending in the axial direction on the inner surface of the outer wall 7a in a region where the slit 17 extends from the upper end to the lower end, the opened second liquid discharging cap 3 is held by hand. By pulling down the hinge band 11 to tear down the score, the outer wall 7a can be completely torn, whereby the first liquid discharging cap 1 can be easily removed from the container opening 100.

An endless score 19a is formed on the top plate portion 9 of the first liquid discharging cap, and a tension ring 19c is provided in a region surrounded by the score 19a via a standing and extending column 19b. By pulling up the ring 19c, the endless score 19a is torn, and the area surrounded by the endless score 19a becomes a communication hole 20 communicating with the inside of the container. In the vicinity of such an endless score 19 a (communication hole 20), a partition wall 21 for liquid storage rises endlessly from the upper surface of the top plate 9. The area surrounded by the partition wall 21 is a liquid reservoir Z, and the liquid is temporarily stored in the liquid reservoir Z in order to dispense a certain amount of the liquid from the second liquid discharging cap 3. (See FIG. 7 described later). As clearly shown in FIGS. 1 and 5, the communication hole 20 is provided in a specific area on one side of the top plate 9, and the liquid reservoir Z is provided in an area other than the specific area.

  A small peripheral protrusion 23 for stably holding the second liquid discharging cap 3 is formed in a peripheral portion of the top plate portion 9, and further has the above-described endless score 19a (communication hole 20) and A pouring projection 25 is provided so as to surround the liquid storage partition wall 21. The pouring projection 25 functions as a guide for the content liquid when the content liquid is discharged from the communication hole 20 formed in the first liquid discharging cap 1, and its upper end has a trumpet-like outer shape. It has a form that has spread.

In the above-described composite liquid discharging cap, the second liquid discharging cap 3 has an annular wall 27 and a ceiling portion 29 formed so as to close an upper end of the annular wall 27.
The lower end of the annular wall 27 is hinged to the upper end of the cylindrical side wall 7 of the first liquid discharging cap 1 by the above-mentioned first hinge band 11 (see FIG. 3). The upper end is hinged to the upper lid 5 by a second hinge band 31. That is, the composite liquid discharging cap of the embodiment of FIGS. 1 to 5 has a double hinge structure, and the second liquid discharging cap 3 is the same as the first liquid discharging cap 1 attached to the container opening 100. An openable and closable hinge is connected so as to be able to cover, and an upper lid 5 is hinged to the second liquid discharging cap 3 so as to be openable and closable so as to be able to cover it.

  In the composite liquid discharging cap of such a form, as shown in FIG. 6, the second liquid discharging cap 3 is opened with the upper lid 5 kept closed (the top plate of the first liquid discharging cap 1). In this state, the tension ring 19c is pulled to tear the score 19a to form the communication hole 20, and then the container is inclined to discharge the content liquid by the first liquid discharging cap 1. (I.e., the same liquid discharging as a normal cap) is performed. That is, the content liquid passes through the communication hole 20 and is poured out to the outside along the inner surface of the cylindrical projection 25.

  Further, in the state where the communication hole 20 is formed as described above, a part of the content liquid is accommodated in the liquid reservoir Z surrounded by the partition wall 21, and in this state, the second liquid discharge cap 3 (Ie, dispensing) of the content liquid is performed. This operation will be described later.

  Note that a first hinge band 11 connecting the first liquid discharging cap 1 and the second liquid discharging cap 3 and a second hinge connecting the second liquid discharging cap 3 and the upper lid 5 are hinged. It is preferable that the hinge band 31 is disposed at an angular interval of 60 to 150 degrees (that is, an angle formed by the central axis lines X and Y). In the illustrated embodiment (see FIGS. 4 and 5), the center axes X and Y of these bands are spaced apart at an angle of 90 degrees. That is, this prevents the opening operation of the upper lid 5 from being confused with the opening operation of the second liquid discharging cap 3 and reduces the size when both the second liquid discharging cap 3 and the upper lid 5 are opened. Can be smaller. For example, this composite liquid discharging cap is formed by injection molding of a predetermined plastic so that the second liquid discharging cap 3 is opened with respect to the first liquid discharging cap 1 and the upper lid 5 is opened. However, in this case, there is an advantage that the molding die can be made compact.

As shown in FIG. 5, a circumferential groove 33 is formed on the inner surface of the lower end portion of the annular wall 27 of the second liquid discharging cap 3 as described above. Is closed, the circumferential groove 33 engages with the small circumferential protrusion 23 formed on the top surface of the top plate 9 of the first liquid discharging cap 1, whereby the second liquid discharging cap 3 is moved. It is stably maintained in the closed state.
As shown in FIGS. 3 and 6, a first opening tab 34 is provided on the upper end portion of the annular wall 27 on the side facing the first hinge band 11. That is, the first opening tab 34 allows the second pouring cap 3 to be easily opened and closed by hand.

Further, as shown in FIG. 1, a small circumferential projection 35 for stably holding the upper lid 5 is also formed on the upper surface of the peripheral portion of the ceiling portion 29 of the second liquid discharging cap 3.
A seal ring 37 is provided on the lower surface of the peripheral portion of the ceiling portion 29. When the second liquid discharging cap 3 is closed, the seal ring 37 is attached to the cylindrical projection 25 of the first liquid discharging cap 1. By tightly contacting the inner surface, the sealing property is ensured.

  On the other hand, the central portion of the ceiling portion 29 has a form that bulges upward, and the bulge portion is provided with a liquid discharge guide cylinder 39 that extends obliquely. That is, the direction of discharging the content liquid dispensed through the second liquid discharging cap 3 is defined by the liquid discharging guide cylinder 39. Inside the guide cylinder 39, a liquid discharging pipe 40 is provided. The distal end portion is fitted, and is stably held inside the guide cylinder 39 without rattling. The inside of the pipe 40 is a space serving as a flow path 40a for the content liquid, and the other end is disposed so as to face the bottom of the above-described liquid reservoir Z (see FIG. 1).

As described above, the liquid discharging pipe 40 is attached to the liquid discharging guide cylinder 39. To seal the distal end of the pipe 40, a small cap 41 is provided at the distal end of the guide pipe 39. Have been.
The small cap 41 has a flat plate-shaped substrate 45 connected to the distal end of the guide cylinder 39 by a band 43 so as to be openable and closable, and a double-walled sealing member provided at the center of one surface of the substrate 45 When the small cap 41 (the plate-like substrate 45) is closed, the tip of the guide cylinder 39 is fitted between the sealing rings 47. The distal end of the dispensing pipe) is sealed so that leakage of the content liquid from the distal end of the pipe 40 is prevented.

  In FIG. 1, the upper lid 5 that is openably and closably connected to the second liquid discharging cap 3 by the second hinge band 31 includes a top plate 49 and a skirt wall 51 that is lowered from the periphery of the top plate 49. On the inner surface of the lower end of the skirt wall 51, a circumferential groove 53 (see FIG. 4) that engages with the small circumferential protrusion 35 provided on the ceiling portion 29 of the second liquid discharging cap 3 described above. When the upper lid 5 is closed as shown in FIG. 1, the small circumferential projections 35 and the circumferential grooves 53 engage with each other, so that the upper lid 5 is Is stably maintained.

A second opening tab 55 is provided on the outer surface of the skirt wall 51 on a side facing the second hinge band 31 connecting the second liquid discharging cap 3 and the upper lid 5. . The second opening tab 55 allows the upper lid 5 to be easily opened and closed by hand.
As understood from FIGS. 4 and 5, when the second liquid discharging cap 3 and the upper lid 5 are closed, the first hinge band 11 and the second hinge band 31 cause the first The opening tab 34 and the second opening tab 55 are completely separated from each other in the circumferential direction, so that the second liquid discharging cap 3 having the first opening tab 34 can be removed. The opening and the opening of the upper lid 5 by holding the second opening tab 55 by hand can be performed completely separately, and these opening operations can be performed promptly without error.

  Further, with reference to FIGS. 1 and 4, on the side where the second opening tab 55 is provided (on the side facing the second hinge band 31), the skirt wall 51 extends from the inner surface of the top plate 49. A plurality (three in the illustrated embodiment) of ribs 57 for regulating the opening and closing of the small cap 41 are formed on the inner surface, and the small cap 41 is sandwiched between the ribs 57 on the lower part of the inner surface of the skirt wall 51. Are formed in a pair.

That is, when closing the upper lid 5, the ribs 57 press the flat substrate 45 of the small cap 41, whereby when the upper lid 5 is closed, the small cap 41 is automatically closed and the guide cylinder 39 ( The tip of the liquid dispensing pipe 40) is sealed. In the state where the upper lid 5 is closed, as shown in FIG. 1, the ribs 57 are in close contact with the small cap 41 (the back surface of the flat substrate 45), so that the small cap 41 is closed. Is stably maintained.
When the upper cover 5 is closed, the protruding piece 59 goes over the small cap 41 (the flat substrate 45). When the closed upper lid 5 is opened, the protruding piece 59 is turned together with the turning of the upper lid 5. The small cap 41 (the flat substrate 45) is pushed up. As a result, at the same time when the upper lid 5 is opened, the distal end of the guide cylinder 39 (the liquid dispensing pipe 40) is also released. It is possible to discharge (dispense) the content liquid from the container 40.

In the present invention, when dispensing the content liquid from the liquid dispensing pipe 40, the content liquid is temporarily stored in the liquid reservoir Z formed in the first liquid discharging cap 1. That is, as described above, after the pull ring 19c is pulled to tear the score 19a to form the communication hole 20, the upper lid 5 and the second liquid discharging cap 3 are closed, the container is once inverted, and Return to the upright position. As a result, as shown in FIG. 7, the liquid in the container (indicated by 90 in FIG. 7) is completely stored in the liquid reservoir Z.
After the liquid reservoir Z is filled with the content liquid 90 in this manner, as shown in FIG. 8, when the upper lid 5 is opened with the second liquid discharging cap 3 closed, the upper lid 5 is opened. Accordingly, the small cap 41 is also opened. Therefore, by tilting the container in this state, the content liquid 90 stored in the liquid reservoir Z is poured out from the tip of the guide cylinder 39 through the liquid dispensing pipe 40.
Thus, in the dispensing through the second liquid discharging cap 3, a fixed amount of the liquid content corresponding to the internal volume of the liquid reservoir Z is discharged.

  The composite liquid discharging cap of the present invention having the above-described structure is formed in a state where the second liquid discharging cap 3 is opened relative to the first liquid discharging cap 1 and the upper lid 5 is further opened. In this state, the tip of the liquid dispensing pipe 40 is fitted into the liquid discharging guide cylinder 39 of the second liquid discharging cap 3. In this manner, in a state where the liquid dispensing pipe 40 is attached to the second liquid discharging cap 3 (liquid discharging guide cylinder 39), the other end of the pipe 40 closes the second liquid discharging cap 3. Is positioned so as to face the bottom of the liquid reservoir Z.

  In the present invention, as described above, the liquid dispensing pipe 40 has its distal end fitted in the liquid discharging guide cylinder 39 of the second liquid discharging cap 3 and the other end thereof has the first liquid discharging cap 1. Is arranged so as to face the bottom of the liquid reservoir Z. In order to enable such an arrangement, the pipe 40 usually has a bent shape as understood from FIG. That is, the guide cylinder 39 is used to regulate the direction in which the content liquid 90 is discharged from the pipe 40 and is used to discharge the content liquid 90 stored in the liquid reservoir Z. It has a form inclined with respect to the axis P of the cap. If the guide cylinder 39 extends in a state parallel or nearly parallel to the axis P, the container must be tilted greatly in order to discharge the liquid from the guide cylinder 39, and therefore, the container is accommodated in the liquid reservoir Z. This is because the content liquid 90 is spilled, and the amount of liquid discharged through the pipe 40 is reduced. As a result of fitting the tip of the pipe 40 into such an inclined guide cylinder 39 and arranging the other end so as to face the bottom of the liquid reservoir Z, the pipe 40 necessarily has a bent form.

  In addition, in order to discharge the content liquid stored in the liquid reservoir Z through the pipe 40 as efficiently as possible, the other end of the pipe 40 facing the bottom of the liquid reservoir Z is connected to the lowermost end when the container is inclined. It is desirable to be located as close to the bottom corner as possible.

  In addition, since the other end of the pipe 40 is disposed so as to face the bottom of the liquid reservoir Z as described above, the upper end of the partition wall 21 forming the liquid reservoir Z is positioned from the peripheral edge of the top plate 9. It is desirable not to protrude too much. If the protruding height (indicated by h in FIG. 1) is too large, the pipe 40 will be caught on the partition wall 21 when the second liquid discharging cap 3 on which the pipe 40 is mounted is turned and closed, This is because the other end cannot enter the liquid reservoir Z. Therefore, when the liquid amount (corresponding to the volume of the liquid reservoir Z) of the content liquid 90 to be dispensed from the second liquid discharging cap 3 (the pipe 40) is increased to some extent, as shown in FIG. 4 and 5, the size of the communication hole 20 formed by tearing the score 19a is reduced, and the partition wall 21 communicates with the partition wall 21 as shown in FIGS. It is desirable to provide so as to surround a part of the hole 20 (score 19a).

Also, in the present invention, when the container is tilted and the content liquid stored in the liquid reservoir Z is discharged, in order to effectively avoid the inconvenience that some liquid spills out of the liquid reservoir Z, FIG. As shown in FIG. 9, it is preferable to form the liquid reservoir Z.
In the embodiment of FIG. 9, the parts other than the form of the liquid reservoir Z are the same as those of the embodiment of FIG.

9, a notch 60 is formed at the upper end of the partition wall 21 in the composite liquid discharging cap of this embodiment. The notch 60 is provided in a portion located on the side opposite to the directing direction (the side opposite to the direction in which liquid is discharged from the guide cylinder 39) of the tip portion of the liquid discharging guide cylinder 30. It has a function as a liquid discharge passage for adjusting the amount of liquid stored in the liquid reservoir Z formed by 21 to a constant amount. As described above, when the container is inverted and then returned to the upright state to fill the container content liquid in the liquid reservoir Z, the liquid located above the lower end of the notch 60 is cut off. The horizontal surface 61 including the lower end of the notch 60 is discharged from the liquid reservoir Z through the notch 60 and collected in the container, and thus becomes a liquid surface of the content liquid stored in the liquid reservoir Z. In such an embodiment, the portion above the liquid surface (horizontal surface 61) is surrounded by the upper portion 21a of the partition wall 21 except for the portion where the notch 60 is formed, so that the liquid surface shakes. Thereby, the inconvenience that the content liquid spills out of the liquid reservoir Z can be effectively prevented. Moreover, when the container is tilted and the content liquid stored in the liquid reservoir Z is discharged from the tip of the guide cylinder 39 through the liquid dispensing pipe 40 (liquid flow path 40a), the side where the liquid flows down is Since the upper portion 21a of the partition wall 21 is present, the amount of liquid spilled from the liquid reservoir Z without being introduced into the liquid flow path 40a of the liquid dispensing pipe 40 can be minimized.
In the example described above, the notch 60 is formed as a liquid discharge path, but a hole may be provided in the partition wall 21 instead of the notch 60. Such a hole is formed in a portion located at the lower end of the notch 60, so that the liquid located in the upper portion of the partition wall 21 can be stored in the liquid storage portion as in the case where the notch 60 is provided. Z can be discharged.

  In this way, as shown in FIG. 9, the provision of the notch 60 at the upper end of the partition wall 21 causes the disadvantage that the content liquid spills out of the liquid reservoir Z without passing through the liquid dispensing pipe 40. Can be effectively avoided, and the amount of the content liquid can be more reliably set to be constant so as to be dispensed.

  Further, as shown in FIG. 9, the bottom portion 63 of the liquid reservoir Z has a tapered inclined surface such that a lower portion becomes lower and an upper portion becomes higher when the container is tilted. It is best to do. That is, the bottom 63 has an inclined surface, and as described above, the liquid dispensing pipe 40 is in close contact with the inner surface of the lower partition wall 21 when the container is inclined for dispensing the content liquid. , The content liquid stored in the liquid reservoir Z can be discharged through the pipe 40 without remaining in the liquid reservoir Z, and a certain amount of the liquid can be discharged more reliably. I can do it.

In the present invention, the above-described composite liquid dispensing cap and liquid dispensing pipe 40 can be made of various thermoplastic resins that can be molded such as injection molding, compression molding, extrusion molding, and blow molding. Is formed of an olefin resin such as polyethylene or polypropylene widely used in the field of packaging or a polyester resin such as polyethylene terephthalate.
Further, the liquid discharging pipe 40 in a bent form as shown in FIG. 1 may be difficult to form, but in such a case, the pipe 40 is formed of a pair of pieces hingedly connected to the pipe 40. By forming a split mold structure, these pieces are formed in an open shape, and closed, so that the bent pipe shown in FIG. 1 can be formed.

  In the above-described composite liquid discharging cap of the present invention, when the second liquid discharging cap 3 is opened, the container is tilted so that the normal liquid discharging can be performed through the communication hole 20 formed in the first liquid discharging cap 1. When the second liquid discharging cap 3 is closed and the upper lid 5 (and the small cap 41 is opened), the container is previously inverted and the content liquid 90 is stored in the liquid reservoir Z in advance. By tilting the container, a fixed amount of the liquid 90 contained in the liquid reservoir Z can be discharged through the pipe 40, and a constant amount of the liquid can be constantly dispensed.

  The composite liquid discharging cap of the present invention discharges the content liquid by ordinary liquid discharging, and at the same time, various liquids which are desired to be discharged in a fixed small amount, for example, soy sauce, dressing, sauces, seasoning liquid such as edible oil and the like. Can be particularly suitably applied as a cap of a container in which is stored.
