Abstract

PROBLEM TO BE SOLVED: To suck the content in a container with a very small suction force, by providing a trough-shaped extraction member held in the container and connected to an extraction nozzle provided in the contractible container. SOLUTION: An extraction nozzle 104 is fitted to the extraction opening 102 for suction so that one end thereof projects outward from the container body 101 and a trough-shaped extraction member 105 is connected to the lower part of the extraction nozzle 104. When sucking the content through the extraction nozzle 104, the uppermost air 111 in the container body is sucked by the vacuum pressure in the container body. When the air is removed, the content flows toward the extraction member 105 and the raw material sheets 112, 112' of the container body are closely stuck on the extraction member 105 to form three passages (a), (a'), (b) at the inside and the outside of the extraction member 105. Accordingly, the content 101 is sucked up through these three passages. In this way, the content in the container can be sucked with a very small force and the content is hardly left in the container.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for dispensing container contents applied to a shrinkable container such as a stand pouch or other bag-like beverage containers.

[0002]

2. Description of the Related Art Conventionally, beverage containers such as soft drinks, alcoholic beverages, and milk include bottles, PET bottles, cans, and paper packs. When drinking the contents from these containers, a straw is usually used to suck out the beverage of the contents.

[0003] The above straw is usually provided separately in a small bag on the outer surface of the container, and is separated from the container when used and inserted into a straw insertion hole provided in the container to suck up the straw. There are many. In addition, there are some which are integrated with the drinking spout and are already stored in the container. In this case, there is no need to insert the straw into the straw insertion hole again, and it is sufficient to suck out the contents from the drinking straw integrated with the drinking spout.

[0004]

However, in the case where a conventional straw is used, the contents such as beverages in the container 201 always come from the bottom of the container as shown in FIG. In this case, the entire length of the straw 202 must be used, even though the passage of the contents such as a beverage is limited to the thickness of the straw 202. Therefore, the flow path resistance is large,
From the beginning to the end of drinking, he had to suck out with considerable force.

[0005] Straws that are usually attached to containers for beverages and the like can be used only if they are too thin because they are protruding from the container if they are too thick, which is dangerous and inefficient packing. . Therefore, especially in the case of a child having a weak suction force, unreacted drinking occurs regardless of the container. At least in the conventional container, the general consumers have experienced the feeling that a slightly thicker straw makes it easier to drink.

[0006] In particular, in a box-shaped container having no passage for air to flow into the container other than the straw, when the negative pressure in the container increases as the amount of beverage decreases, the suction force is reduced. It became impossible to win, and it was necessary to once introduce air from the straw into the space inside the container, return the inside of the container to normal pressure, and then suck it out again. Therefore, there is a case where the inside of the container does not become a strong negative pressure by crushing the container while drinking, but there is also a case where the beverage is spouted out by applying force. Furthermore, the sound generated when air flows from the straw into the container gives a very vulgar impression.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, and when sucking out contents such as beverages from a container, sucking up with very light suction force and very smartly. It is an object of the present invention to provide a mechanism for dispensing the contents of a container capable of discharging the contents.

[0008]

That is, a mechanism for dispensing the contents of a container according to the present invention comprises a dispensing nozzle provided on a shrinkable container and a gutter connected to the dispensing nozzle and held in the container. (Toy) -shaped pouring member.

[0009] The container contents pouring mechanism of the present invention is also characterized in that the trough-shaped pouring member is formed with a notch at a desired position in the length direction of the edge.

[0010] In the container contents pouring mechanism of the present invention, the flexible sheet forming the shrinkable container may have different thicknesses at positions sandwiching the trough-shaped pouring member. Is also featured.

Since the present invention is structured as described above, the contents in the container can be sucked out with a very small suction force, and the contents of the container can be sucked out with very little unsucked residue. A mechanism can be provided.

[0012]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a container content pouring mechanism according to the present invention.

FIG. 1 is a conceptual view showing an embodiment of a container content discharging mechanism according to the present invention.

In FIGS. 1A and 1B, reference numeral 102 denotes
Denotes a spout for suction attached to the upper part of the container body 101 formed by bonding material sheets, and the spout 10
A discharge nozzle 104 is attached to 2 as a hollow accessory so that one end thereof protrudes outward from the container body 101. Numeral 105 denotes a gutter-shaped pouring member connected to a lower portion of the pouring nozzle 104.

In the figure, the material of the container body 101 can be selected from a plastic sheet, a metal sheet, or a composite sheet using these as a constituent material. Examples of the plastic sheet include polyethylene, polypropylene, polyester, polycarbonate, nylon resin and the like. These soft sheets or composite sheets are used as materials, and two material sheets are attached to each other and the periphery thereof is heat-sealed with a predetermined width, thereby being formed by heat welding. The lower portion of the container body 101 is welded with a bottom sheet 103 folded downward therebetween. Therefore, when the contents are filled in the container body 101, the folded portion opens, and the bottom sheet 103 spreads to form the bottom of the container.
Therefore, when the container main body 101 is placed on a table or the like in this state, it becomes self-supporting without any support.

FIGS. 2A to 2E show an example of a gutter-shaped pouring member 105. FIG. That is, FIG.
As shown in (b) and (b), a gutter-shaped pouring member 105 is integrally connected to the lower end of the pouring nozzle 104 located inside the container body 101 so as to be hung downward. More specifically, a part 106 of the peripheral wall of the injection nozzle 104 formed in a funnel shape tapered upward.
Is extended downward, and a gutter-like pouring member 105 is provided at the end thereof. It is desirable that the pouring nozzle 104, the pouring member 105, and the like also be made of the same material as the container body 101, both in terms of manufacturing and disposal.

The discharge nozzle 104 is joined to the container body 101 at its maximum width portion 107 by heat welding. An ejection member 105 formed by being connected to the ejection nozzle 104.
Has a cross-sectional shape of a gutter having a predetermined arc-shaped cross-section as shown in FIG. 1 (c). However, even if it has a V-shaped cross-section as shown in FIG. ) May be a gutter shape having a U-shaped cross section.

The pouring member 105 is provided with the pouring port 102 in advance.
It is arranged in the container body 101 at the position (see FIG. 1). Therefore, unlike the case where the container is attached to a conventional container, the size or the like is not restricted by the drinking spout or the like, so that the size can be freely set. For example, in the above embodiment, the flow passage area of the pouring member 105 is set to be equal to or larger than the flow passage area of a straw attached to a conventional container.

The spouting nozzle 104 and the spouting member 105 may be formed integrally or may be formed separately by welding or the like. It is desirable that it be held and bend freely. In addition, the pouring member 10
It is desirable that the material 5 itself has appropriate flexibility from the viewpoint of preventing damage to the container.

FIGS. 3A to 3E show another example of the gutter-like pouring member 105. FIG. In this example,
Notches 109 (six in the figure) are provided at the edge 108 of the gutter-shaped pouring member 105 at a desired interval.

When the contents 110 are sucked up from the container body 101 provided with the pouring member 105 configured as described above, the pouring member 105 functions as follows.

In FIGS. 4A and 4B, the spout 10
When the suction nozzle 104 provided in the container 2 is sucked up with a mouth, first, the container body 10
1, the air 111 at the uppermost part is sucked out and the air 111
Material sheet 1 forming the container body from the portion where
12, 112 'come into close contact. However,
At this time, dimensional or shape considerations should be given to the design so that the material sheets 112 and 112 ′ do not adhere to the extension 106 at the lower end of the discharge nozzle 104 and block the passage of contents such as beverages. is necessary.

When the air 111 escapes, the contents 110 flow toward the pouring member 105. As shown in FIG. 4C, the material sheets 112 and 112 ′ of the container body 101 are in close contact with the pouring member 105 around the pouring member 105, and three passages a, a ′ and b is formed. Therefore, the contents 110 are sucked up through these three passages a, a ', b. However,
As described above, only the flow path area of the pouring member 105 is equal to or larger than the flow area of a normal straw,
Even if only three passages are obtained in this way, a flow passage area far exceeding a normal straw can be secured. The flow path area can be freely set by adjusting the width or the depth of the pouring member 105, so that the flow path area can be set to be the most easy to drink.

FIG. 4D shows a case where the notch 109 is not formed at the edge 108 of the gutter-shaped pouring member 105.

The material sheet 112, 112 'at the part from which the air 111 has escaped is brought into close contact with the material sheet 112, so that the content 1 is removed.
10 will be sucked out from the top 113. In other words, since the water can be sucked up from the position closest to the entrance and through a wide passage, it is possible to easily suck up even a small suction force. At this time, if air is prevented from entering from outside, the material sheet 112 of the container body 101,
112 'gradually comes in close contact from the top downward, and acts as if the contents in the tube are pushed out, so that the contents 110 are always sucked up from the top 113 thereof.

That is, FIGS. 5A to 5C and FIG.
As shown in (a) to (c), the contents 110 are placed in the passages a and a ′ outside the pouring member 105 or the nearest notch 1.
09 flows into the pouring member 105 and is sucked out from the three passages a, a ', and b. And FIG.
As shown in (c), the content 110 is sucked out from the tip of the pouring member 105 only when the remaining amount of the content 110 becomes small.

FIGS. 5 to 7D show a case where the notch 109 is not formed at the edge 108 of the gutter-shaped pouring member 105. FIG.

The material sheet 11 of the container body 101
When the portion where 2,112 'adheres increases,
In some cases, wrinkles 114 may occur in the container main body 101, and the contents flowing into the wrinkles 114 by capillary action are also sucked out from the passage closest to the wrinkles 114, so that the last drop is relatively small. It is sucked out by the sucking force, and the remaining unsucked (drink remaining) is extremely small. In other words, in accordance with the uppermost portion 113 which changes depending on the capacity of the contents 110, the same phenomenon as in the case where the length of the straw has been extended steplessly with the minimum length is realized here. .

In the above-described stand-pouch-shaped container body 101, in order to ensure that the passages a and a 'are formed outside the pouring member 105, for example, the arc of the pouring member 105 is formed. It is desirable that the chord-side material sheet 112 ′ is made somewhat thicker than the arc-side material sheet 112 of the pouring member 3, and the degree of deformation when closely contacting the pouring member 105 is changed. By doing so, the close contact of the material sheet 112 'on the chord side of the arc of the pouring member 105 is suppressed, and the ideal material sheet shown in each cross-sectional view of FIGS. The formation of a passage can be realized.

FIGS. 8 and 9 are conceptual views showing another embodiment of the mechanism for discharging the contents of a container according to the present invention.

8 (a) to 8 (c), at the upper part of a container body 121 formed by bonding material sheets, a spout 122 for filling and a filling port 123 are provided in the thickness direction of the material sheet. It is. A spout nozzle 124 is attached to the spout 122 as a hollow accessory so that one end thereof protrudes outward from the container body 121, and a gutter-shaped spout member 125 is provided below the spout nozzle 124.
