Description

  The present invention relates to a paper container containing contents such as liquid or viscous substances such as sake, shochu, whiskey, wine, shampoo, rinse, dressing, ketchup, mayonnaise, or various cleaning liquids. In particular, the present invention relates to a paper-type paper container having an extruding function for extruding an object.

  Conventionally, paper containers that contain liquids such as sake, shochu, whiskey, wine, shampoo, rinse, dressing, ketchup, mayonnaise, or various cleaning liquids and viscous materials are easy to mold and retain shape. In general, a paper base is used from the standpoint of light shielding properties and light shielding properties, and a plastic film on which an aluminum foil or an inorganic material such as aluminum, silicon oxide, or aluminum oxide is deposited is used from the viewpoint of gas barrier properties. It is used for.

  Specifically, as a configuration used for a paper container, for example, a high-pressure method low-density polyethylene layer (hereinafter referred to as an LDPE layer) / paper layer / LDPE layer / aluminum foil / adhesive / biaxially stretched polyethylene terephthalate film (hereinafter referred to as an LDPE layer) , PET film) / LDPE layer or medium density polyethylene layer (hereinafter referred to as MDPE layer) is generally used, and in the above configuration, the step of laminating the aluminum foil and the PET film is performed. Low cost LDPE layer / paper layer / LDPE layer / aluminum vapor deposition layer / PET film / LDPE layer or LDPE layer / paper layer / LDPE layer / silicon oxide vapor deposition layer (or aluminum oxide vapor deposition layer) / PET film / LDPE layer is used.

  However, since the paper container having the above-described configuration hardly deforms, when discharging the contents, only the operation of tilting the paper container can be performed. For example, the container is deformed by pushing the container like a container such as a plastic bottle. In addition, there is a problem that the operation of forcibly discharging the contents cannot be performed, and particularly when the contents have a high viscosity, there is a problem that it takes time to discharge.

As a solution to this problem, there has been proposed a paper container in which a pushing portion is provided in a ridge line portion or the like that constitutes a body portion of the paper container (see, for example, Patent Document 1). However, the paper container disclosed in Patent Document 1 cannot be pushed any further once it has been pushed in, and in order to repeatedly push it in, the pushing part has to be restored each time. was there.

The said side which comprises the trunk | drum connected to the inclination roof part formation board 3a provided with the pouring member 10 used as the said pouring port of the two side plates 4 and 2 (refer FIG. 9) in the direction orthogonal to the side plate 3 At both end portions on the face plate 3 side, a notch portion 11 having a substantially mirror-shaped cross section is provided so as to face each other.

  FIG. 10 is a perspective view showing a fifth embodiment of the paper-belt type paper container according to the present invention, and FIG. 11 is a plan view showing a blank plate of the paper-top paper container of the fifth embodiment shown in FIG. The pattern container P5 has a pouring member 10 serving as a spout on an inclined roof portion, and constitutes a trunk portion connected to the inclined roof portion forming plate 3a having the pouring member 10 serving as the spout of the inclined roof portion. At one end of the side plate 3 and an end of the side plate 4 connected to the other end on the other end side, a notch portion 11 having a substantially mirror-shaped cross section is positioned in the vertical direction of the barrel portion. Are also provided.

  By the way, in embodiment, although the thing which made the notch part 11 into the substantially rectangular shape by which the corner | angular part was chamfered in the curved surface shape, or the cross-sectional substantially mirror shape was shown, the notch shape of the notch part 11 is not restricted to this, An appropriate shape can be adopted. Further, the notch shapes of the two notch portions 11 may be symmetric or asymmetric, or the notch shapes may be different. Further, the side plate 2 to the side plate 3 are notched as much as possible at the approximate center of the cutout portion 11 in the top-bottom direction in consideration of repeatedly pressing the portion sandwiched between the cutout portions 11 with fingers and the depth to be pushed in. It is desirable that the portion 11 is configured to approach. In addition, the position where the cutout portion 11 is provided is such that the center in the top-down direction of the cutout portion 11 is located at a position approximately 1/3 from the top of the top portion of the body portion of the gobeltop paper containers P1 to P5. Appropriately provided, and the vertical dimension of the notch 11 is 20% or more, preferably 30% or more, less than 50% of the vertical length of the body part of the paper-belt type paper containers P1 to P5. It is. The reason for this is that if it is 50% or more, there is a possibility that it will not be broken by the crease provided with the notch 11 during box making, and if it is less than 20%, there is a possibility that a sufficient pressing depth cannot be obtained.

Further, in the embodiment, the side plate 2 to the side plate 3 are provided with one ruled line 12 that connects the notch portion 11, but the ruled line 12 is not limited to one. For example, when the basis weight of the paper layer is large or when it is desired to reduce the repeated pressing force, two or more ruled lines may be used, and the shape is not limited to a straight line. Or two arcuate or arc-shaped ruled lines may be arranged so that the central part is separated or the central part approaches. It is.

  FIG. 12 is a schematic diagram for explaining the usage state of the first embodiment of the paper-belt type paper container according to the present invention, in which the pouring member 10 of the gear-top paper container P1 is opened to provide a spout, and thereafter The contents can be forcibly discharged by holding the top pattern paper container P1 with one hand and repeatedly pressing the finger nipping portion of the side plate 3 with the fingers (in the direction of the arrow in the figure). And the gobeltop type paper container of the present invention performs an operation of forcibly discharging the contents by holding it with one hand and repeatedly pushing it with fingers (in the direction of the arrow in the figure). The present invention is a 40 mm square to 70 mm square. It is particularly suitable for a gobeltop paper container having a barrel with a range of squares. Although not shown, the second to fifth embodiments are used in the same manner as in the first embodiment, and the portions sandwiched between the cutouts 11 of the side plates 2 to 3 are repeated with fingers. The contents can be forcibly discharged by pressing.

  As described above, in the conventional bevel-top type paper container, the paper layer in the layer structure uses a cardboard having a basis weight of 200 g / m 2 to 480 g / m 2 in order to secure the shape at the time of distribution or use. As a result, it must be a rigid container, and it was extremely difficult to forcibly discharge the contents. By adding the function of being able to forcibly discharge the contents, the range of applications of the Gobeltop paper container can be expanded, and the contribution to social life is immeasurable .

≪Example of shifting the notch height position≫
The container P7 shown in FIG. 13 is different from the container P1 of the first embodiment shown in FIG. 1 in that the height positions of the two notches 11 and 11 are shifted from each other. That is, in FIG. 13, the left notch 11 is disposed at a relatively low position, and the right notch 11 is disposed at a relatively high position.
In FIG. 13, the ruled line 12 is formed horizontally at the height position where the left and right cutout portions 11, 11 overlap. However, ruled lines may be formed in an oblique direction.
By making the height positions of the left and right cutouts different, the strength of the panel side plate 3 that forms the container body can be increased compared to the case where the left and right cutouts are at the same position, and the container can be prevented from being crushed. There is a merit that it is possible to maintain the function of forcibly discharging the contents.

  Similarly, the containers of the other embodiments may be arranged by shifting the height positions of the left and right cutouts.

≪Example of intermittently forming cutouts≫
The container P8 shown in FIG. 14 differs from the container P1 of the first embodiment shown in FIG. 1 in that notches are intermittently formed along the container ridgelines 15 and 16. That is, the container P8 of FIG. 14 is obtained by making each notch part 11 with which the container P1 of FIG. 1 is provided is two (11a, 11b) up and down along the ridgelines 15 and 16, respectively. The merit of providing the notch intermittently is as follows.
The container is assembled from, for example, the flat blank plate P1 ′ shown in FIG. 2. At this time, the ridgelines 15 and 16 where the notches are formed are also formed by folding the creases on the blank plate. When folding a crease, (b) the fold can be more clearly formed by dividing the crease by a small notch than by dividing the crease by a large notch.
That is, when sticking the body part during the manufacturing process, that is, when performing frame sealing, the ruled line part is squeezed and folded with the guide member so as to overlap the side plates 1 and 5 sequentially from the roof part side or the bottom part side. Go. For this reason, as in the latter (b), when the paper portions 15β and 16β (see FIG. 14) of the base material for guiding the progress of the folding exist between the notched portions, the folding meanders. There is a merit that it can be folded beautifully.

In the example of FIG. 14, two ruled lines 12 a and 12 b that connect adjacent notch portions are formed on the top and bottom, but only one of them can be omitted or omitted. In addition, a notch part may be divided | segmented into 3 or 4 or more, and the number is arbitrary.
Similarly, the container according to the other embodiment can be folded beautifully by dividing the cutout portion so that the body portion is bonded together (at the time of frame sealing) without folding.

≪Containers other than Gobeltop type≫
In the example described above, all the paper containers are of the govel top type having an inclined roof on the upper part. However, in the present invention, the overall shape of the container is not limited to a specific one. Both the surface and the bottom may be a flat container. Further, the form of the pouring part for taking out the contents is not limited to the structure in which the pouring member 10 which is a separate member is attached, and may be a structure in which a part of the container is opened.
Each of the containers P11, P17, and P18 in FIGS. 15A to 15C is a modified example of the containers P1, P7, and P8, and the top surface is flat, and the top surface is A structure that can be opened is used. Similarly, for the containers P2 to P5 of the other embodiments, a form other than the govel top type may be adopted.

≪Example of a bell-top type with an irregularly sloped roof≫
For example, in the container of the bell type shown in FIG. 1, the area of the inclined roof 3a is generally smaller than that having a flat roof as shown in FIG.
Since the pouring member 10 is provided on the inclined roof 3a in the gobeltop container, the pouring member 10 inevitably has a small diameter when the area of the inclined roof 3a is reduced. If the dispensing member 10 has a small diameter, there is a problem that fingers are not applied to the pull tab and it is difficult to open. In particular, when the diameter (horizontal cross-sectional area) of the container is small, that is, when the container is thin, such a problem tends to be a problem.

A configuration for solving this problem is shown in FIG. In the govel top container P20 of FIG. 16A, the two inclined roofs 3a and 3b constituting the govel top are irregularly configured. In the case of a gobeltop container, generally, as shown in FIG. 16 (b), the two inclined roofs have the same area and are inclined at the same angle. Are different in inclination angle between one inclined roof 3a and the other inclined roof 3b.
Thereby, compared to the case of FIG. 16B in which two inclined roofs are inclined at the same angle, a large area of one inclined roof 3a can be secured (the area of the other inclined roof 3b is small). But). And it has devised so that the extraction member 110 having the largest diameter can be used as much as possible by arranging the extraction member 110 on the inclined roof 3a having the larger area.
As can be seen by comparing FIGS. 16A and 16B, in FIG. 16A, the diameter of the pouring member 110 is increased by the amount of the area of the inclined roof 3a.

≪Example in which the notch is devised so that the inside of the container is easy to see≫
The notch 11 in each of the embodiments of the present invention described above is provided in order to make it easier to discharge the contents by partially weakening the strength of the container and repeatedly pressing the portion. Therefore, it is not always necessary that the inside of the container can be visually observed through the notch 11.
However, in FIG. 3, if the container wall surface (intermediate layer B and inner layer C) remaining on the lower side of the cutout portion 11 is made transparent and the cutout portion 11 is configured like a window, the inside of the container is visually observed. The advantage that the remaining amount and the like can be confirmed is added. In that case, it is preferable to provide at least two notches 11 (windows), and it is more preferable that the two windows exist at opposing positions (almost 180 ° opposite side) on the peripheral wall of the container. By comprising in that way, the inside of a container can be clearly visually confirmed from the other window, taking in light from one notch part (window).

  An example of the arrangement of the notches (windows) 11 that satisfies such a condition is shown in FIG. Each container has at least two notches (windows) 11 and includes two notches (windows) 11 disposed so as to face each other at approximately 180 °.
