Description

  The present invention relates to a set of liquid packaging containers for containing liquid seasonings.

Conventionally, liquid seasonings such as soy sauce and sauces are often sold in containers made of synthetic resin so that general consumers can easily use them at a table. In such plastic packaging containers that contain liquid seasonings, it is possible to reliably prevent leakage of stored items at the distribution stage, such as during store display, and for general consumers who have purchased the products to make small amounts as needed. The inside plug that also serves as a spout is fitted into the neck of the container body so that the neck can be poured out, and the neck is closed, and the purchaser positions the spout opening planned portion provided in the spout A pulling plate with a pull ring is removed and opened, thereby pouring out the liquid seasoning of the contents, and when not in use, a cap is put on to prevent dust and the like from entering the inside of the container body from the spout.
Furthermore, in such a liquid packaging container, a relatively large amount of the contained item is poured out from the spout opening formed by opening the inner stopper by a single tilting operation, and the contained item can be contained in a small amount as necessary. In order to be able to pour out, the pour-out member with a pour tube smaller in diameter than the pour-out opening at the pour-out opening is integrated with the hinge to change the degree of the pour-out from the purchaser. The device which made it possible is shown by patent document 1,2.

By the way, among the above-mentioned liquid seasonings, the sauce (Worstershire sauce) can be broadly classified into high-viscosity and low-viscosity, and products used in general households are high-viscosity (concentrated sauce) Squeeze out from the dispensing cylinder and release the force that pushes the container, pulling the source in the dispensing cylinder back into the container, and products with low viscosity Pour out (concentrated sauce) by tilting the container, and make sure that a little funnel is opened at the tip of the pouring cylinder so that the liquid will not turn over and fall when the container is raised. Some products try to run out of liquid. In addition, in this low-viscosity product, an inflow passage of air into the container body is formed on the inner side of the dispensing cylinder so that pulsation does not occur when the container is tilted and poured. The spout opening scheduled portion is formed so that the spout itself is not a circle but an oval shape or a cross shape.
In such liquid seasonings, products such as sauces are sold as series products with the same shape and shape of the packaging container itself, even if the viscosity, taste and color are different.

However, since the mechanism for running out of liquid is different depending on the viscosity of the liquid to be stored, even if the container body is shared by the packaging container for the high-viscosity liquid seasoning and the packaging container for the low-viscosity liquid seasoning, other members However, there is a problem in that the high-viscosity one and the low-viscosity one have locally different structures, and it is not possible to reduce the manufacturing cost due to common use of members.
That is, a packaging container containing a high-viscosity one has a dispensing tube with a small inner diameter so that the inside plug having a dispensing opening scheduled portion is fitted to the neck of the container body, and further, this inside plug is covered. After the pouring tool is attached, the cap is put on. On the other hand, in a packaging container containing a low-viscosity one, a spout cylinder with a liquid stopper-preventing inner plug with a spout opening planned part is also integrated, and this is attached to the neck of the container body The cap is put on. The cap itself also has a small-diameter seal ring (for high-viscosity liquid seasoning packaging containers) so that the tip side of the small-diameter dispensing cylinder can be closed, and closes the distal end side of the larger dispensing cylinder. It is necessary to have a seal ring (for low-viscosity liquid seasoning packaging containers) In this way, the members other than the container body are partially different in shape, so the cost can be reduced by sharing the members. It was difficult to do.
Therefore, the present invention has been made in view of the above circumstances, and only for one part, a packaging container containing a high-viscosity liquid seasoning and a packaging container containing a low-viscosity liquid seasoning. Set and share other parts, and by selecting the above-mentioned one part that prepared two types, it is possible to make a separate packaging container for high-viscosity liquid seasoning and packaging container for low-viscosity liquid seasoning The purpose of this is to reduce costs by sharing parts.

The present invention has been made in consideration of the above problems, and a container main body having a shoulder around the neck, and the neck of the container main body is fitted to the neck to cover the neck, and the spout opening planned portion is provided. And can be placed on the top of the container body so as to cover the inner plug in which the spout is formed by removing the planned opening of the spout and the neck and shoulder of the container body, respectively. Two lower caps each having a dispensing tube in a corresponding portion facing the inner plug, and one lower cap that can be attached to each of the lower caps and covers the dispensing tube of the lower cap when attached to the lower cap With an upper cap,
Each of the two lower caps is provided with the same outer peripheral shape, and has a protruding portion on the inner surface of the lower end of the outer periphery that releasably engages with the outer periphery of the shoulder of the container body, and corresponds to the inner plug. The portion protrudes upward, and a seal ring that contacts the inner periphery of the inner plug is provided on the inner surface side of the corresponding portion,
Wherein among the two bottom caps, Ri pouring cylinder small diameter der than pouring cylinder of the other of the lower cap of one of the lower cap,
The upper cap is provided with a connecting cylinder on the inner peripheral surface on the inner peripheral surface of which an inner screw that can be screwed to the outer peripheral surface of the corresponding portion facing the inner plug in the lower cap is provided. The corresponding part is provided with a seal ring that slidably contacts the inner circumference of the lower cap when the upper cap is attached ,
The protruding portion on the outer periphery of the lower cap and the container main body engage with each other on the outer side of the container from the position of the screwed portion between the connecting cylinder of the upper cap and the lower cap at a position viewed from above the container. Part is located,
As a container form, a first container form comprising the container body, an inner stopper, one lower cap and an upper cap, the outer peripheral shape of the upper cap being continuous with the outer peripheral shape of the one lower cap, and the container main body and the middle A liquid comprising a stopper, the other lower cap, and an upper cap, wherein the outer shape of the upper cap can be selected from a second container form continuous with the outer shape of the other lower cap. A packaging container set is provided to solve the above problems.

According to the present invention, one container main body, one inner stopper, two lower caps having different structures and one upper cap are used as the container form as described above. And a first container form made up of an upper cap and a second container form made up of the container main body, the inner stopper, the other lower cap and the upper cap. In the packaging container of the first container type with the smaller inner diameter of the container, by storing a high-viscosity liquid seasoning in this, as in the case of a conventional high-viscosity liquid seasoning container, liquid dripping is performed by a squeeze operation. In the second container type packaging container having pulsation prevention means, a low-viscosity liquid seasoning can be contained in this packaging container by containing a low-viscosity liquid seasoning. Suppresses pulsation in the same way as a container for food, and dripping The low-viscosity liquid seasoning without time difference can dispense.
In addition, the container main body, the inner cap, and the upper cap other than the lower cap may each be one kind, and the quantity effect by producing many can be obtained to reduce the manufacturing cost of the entire container.

Next, the present invention will be described in detail based on the embodiment shown in FIGS.
In FIG. 1, reference numeral 1 denotes a liquid packaging container set. As shown in FIG. 1, the liquid packaging container set 1 includes a container body 2, an inner plug 3, two lower caps 4, 5 and an upper cap 6. .
(Container body)
First, the container body 2 is made of a synthetic resin having a vertically long shape. The shoulder portion 8 around the neck portion 7 has a substantially circular shape in plan view, and the outer peripheral portion of the shoulder portion 8 has a stepped shape. It is continuous with the cylindrical body. (Figure 3)
(Inner plug)
An inner plug 3 made of a synthetic resin that is softer than the container body 2 is fitted to the neck portion 7 of the container body 2 so as to be covered from above. In this inner plug 3, as shown in FIGS. 8 and 9, the inner peripheral wall portion 10 that is continuous with the upper end of the outer peripheral wall portion 9 that engages with the outer peripheral surface portion of the neck portion 7 is located inside the neck portion 7. The inner peripheral wall portion 10 is in close contact with the inner peripheral surface of the neck portion 7, and the outer peripheral wall portion 9 and the inner peripheral wall portion 10 are formed in a cylindrical shape so that the inner peripheral wall portion 10 is not detached from the neck portion 7 in a normal handling level. The wall is sandwiched. And the bottom face part 11 is provided so that the lower end of the said inner peripheral wall part 10 used as the inner side of the neck part 7 may be followed, and in this bottom face part 11, a closing board is distribute | arranged via the cyclic | annular thin part, and this closure A spout opening planned portion is formed so that a spout can be obtained by removing the plate, and a pull ring for facilitating the removal operation is provided integrally with the closing plate. (Fig. 4)
In this way, the inner plug 3 protects the contents (liquid seasoning such as sauce) of the container body 2 by being fitted to the neck 7, and even if the container falls down during the distribution stage, etc. When the pull ring is pulled up to remove the portion of the closing plate, a substantially circular spout opens at the spout opening planned portion so that the contents can be passed therethrough.

  The inner plug 3 in the liquid packaging container set 1 does not have a dispensing cylinder that makes the liquid breakage during dispensing good. Therefore, the inner plug 3 is used in both cases of a packaging container for a high-viscosity liquid seasoning described later and a packaging container for a low-viscosity liquid seasoning. In addition, since it does not have a pouring cylinder, the concave space where the pull ring of the inner plug 3 is arranged has a sufficient area that allows easy finger operation to put the fingertip and hook the pull ring. Yes.

(Lower cap)
Each of the lower caps 4 and 5 can be covered from above so as to cover the neck portion 7 of the container body 2 and the inner plug 3 fitted to the neck portion 7 and the shoulder portion 8 around the neck portion 7 ( 8 and 9), the outer peripheral shape of the lower caps 4, 5 is continuous with the outer peripheral shape of the container body that is formed into a substantially rectangular tube shape that gradually narrows upward, and is further related to the outer periphery of the shoulder 8. It is detachably engaged and can be detached by performing an operation such as rotating around the longitudinal central axis of the container body 2 and is made of a synthetic resin. The attaching / detaching operation of the lower caps 4 and 5 with respect to the container body 2 is not particularly limited to the rotating operation.
Of the two lower caps 4 and 5, one lower cap 4 is used as one of the container components when the stored item is a high-viscosity liquid seasoning, and the other lower cap 5 has a lower stored item. When it is a liquid seasoning of viscosity, it is used as one of the container constituent members.

The corresponding portion 12 facing the inner plug 3 when the lower cap 4 is placed on the upper portion of the container body 2 is formed so as to protrude upward as shown in FIG. Is provided with a seal ring 13 which is in close contact with the inner peripheral wall portion 10 of the inner plug 3, and further, a pouring tube 14 which protrudes upward is provided at the center of the corresponding portion 12, so that the lower cap 4 is attached to the container body. 2, the recessed space portion of the inner plug 3 is communicated with the upper space of the lower cap 4 through the pouring tube 14. Therefore, in the packaging container using the lower cap 4, when the contents are poured out by opening the pouring outlet, the contents are poured out only from the dispensing cylinder 14.
The outer diameter of the extraction cylinder 14 is set smaller than the inner diameter of the extraction cylinder of the lower cap 5 described later. The inner diameter of the dispensing cylinder 14 in this example is the same as the inner diameter of the dispensing cylinder employed in a packaging container that dispenses a conventional high-viscosity liquid seasoning by a squeeze operation. The inner diameter is such that when the squeeze operation is finished and the force to push the barrel of the container body is no longer applied, the contents in the dispensing tube are pulled back to the inside of the container body to properly drain the liquid.

The other lower cap 5 is also formed on a corresponding portion 15 opposite to the inner plug 3 at the top of the container main body 2 so as to protrude upward as shown in FIG. In the same manner as in the lower cap 4, a seal ring 16 that is in close contact with the inner peripheral wall portion 10 of the inner plug 3 is provided on the inner surface side thereof. Further, the corresponding portion 15 is provided with a pouring cylinder 18 having an inner diameter larger than the outer diameter of the pouring cylinder 14 of the lower cap 4, and the tip of the pouring cylinder is expanded in a funnel shape so that the liquid is formed on the outer periphery. A cutting bar 17 is arranged so that when the lower cap 5 is put on the container body 2, the recessed space portion of the inner plug 3 communicates with the upper space of the lower cap 5 through the pouring cylinder 18. Therefore, in the packaging container using the lower cap 5, when the contents are poured out by opening the pouring outlet, the contents are poured out only from the pouring cylinder 18.
As described above, the lower cap 5 is one of the container constituent members in the packaging container for the low-viscosity liquid seasoning, so that no pulsation occurs when the low-viscosity liquid seasoning is poured out. The pulsation preventing means 19 is provided. The pulsation preventing means 19 is composed of a tongue piece projecting from the four sides toward the central axis side of the pouring cylinder 18 at the end of the pouring cylinder 18 on the inner plug 3 side. The opening shape of the section is made substantially cross-shaped, and when the container is tilted to pour out the contents, the flow of the contents to the tip end side of the dispensing cylinder is restricted so that air can easily enter. Yes.

(Upper cap)
The upper cap 6 is made of a synthetic resin that can be detachably attached to the lower caps 4 and 5. And when the upper cap 6 is attached to each of the lower caps 4 and 5, the above-mentioned extraction cylinders 14 and 18 of the lower caps 4 and 5 are covered. Further, as shown in FIG. 2, the outer peripheral shape of the upper cap 6 is continuous with the outer peripheral shape of the lower caps 4 and 5 in the state of being put on the lower caps 4 and 5 (the outer peripheral shape of the lower caps 4 and 5 is The same). Further, the attachment of the upper cap 6 to the lower caps 4 and 5 is by screwing screws, and as shown in FIG. 7, screws are attached to the outer peripheral surfaces of the corresponding portions 12 and 15 of the lower caps 4 and 5. The connecting cylinder 20 is provided on the inner side with an internal thread that can be formed on the inner peripheral surface. Then, as shown in FIGS. 8 and 9, by attaching the upper cap 6, the position of the connecting portion 20 of the upper cap 6 and the lower cap 4 and the screwed portion between the lower caps 4 and 5, A portion where the protrusions on the outer periphery of the lower caps 4 and 5 engage with the outer periphery of the shoulder portion 8 of the container body 2 is positioned.
The upper cap 6 is put on the lower caps 4 and 5 to prevent foreign matter and the like from entering the inside of the container main body 2 from the dispensing cylinders 14 and 18. Further, in the case of a container using the lower cap 4, the tip end side of the pouring cylinder 14 of the lower cap 4 is closed, and the pouring cylinder of the lower cap 5 in the case of a container using the lower cap 5. 18 is closed to prevent the contents from flowing out to the outside even when the container falls down. For this reason, the upper cap 6 and the lower cap 4 A seal ring 22 slidably in contact with the inner peripheral surface of the extraction cylinder 14 of the lower cap 4 when attached is provided. Similarly, the inside of the extraction cylinder 18 of the lower cap 5 when attached to the upper cap 6 and the lower cap 5 A seal ring 23 slidably contacting the peripheral surface is provided.

Thus, in this liquid packaging container set 1, one container main body 2, one inner plug 3 fitted to the neck portion 7 of the container main body 2, and the upper part of the container main body 2 fitted with the inner plug 3 respectively. Two lower caps 4, 5 that can be put on the cover, and one upper cap 6 that can be put on either of the two lower caps 4, 5. And a first container form including the lower cap 4 and the upper cap 6 and a second container form including the container main body 2, the inner stopper 3, the lower cap 5, and the upper cap 6 can be selected. As described above, the first container form can be adopted when a packaging container that contains a high-viscosity liquid seasoning is used, and the second container form is when a packaging container that contains a low-viscosity liquid seasoning is used. Can be adopted.
Of course, when manufacturing packaging containers, it is not necessary to prepare a single packaging container set for the liquid per packaging container, but a high-viscosity liquid seasoning product or a low-viscosity liquid seasoning product. The lower cap is selected when the container component is supplied to the production line.
