Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a quadrangular prismatic paper pack that encloses beverages such as milk, juice, oolong tea, and sake, and in particular, when it is sealed, the part folded inside the head is pulled out to open the spout. It relates to paper packs that do.

[0002]

[Prior art]

 Such a conventional paper pack will be described with reference to FIGS. 7 (A), (B) and (C). At the head of the quadrangular prism of the paper pack 101, a pair of facing edges are head folding sides 102 and 103 which are bisected at the time of closure and folded back to the outside so that the folding points touch each other. There are head folding surfaces 102a and 103b that are continuous inward of the head, and the other one pair of facing edges has heads that sandwich the head folding edges 102 and 103 that are adjacent to each other when the head is closed. The portion sandwiching sides 104 and 105, and the inside thereof are the head sandwiching surfaces 104h and 105i to be in surface contact with the head folding surfaces 102a and 103b. The opening is performed by forming a portion near the folding point as a drawer portion and pulling it out to form a spout f 1 as shown in the drawing.

First, as shown in FIG. 7C, the portion forming the spout f at the time of opening, that is, the spout-portion-constituting surfaces 102a, 103b, c, d, and e in the figure are pulled out and closed at the same time. By opening the head sandwiching surfaces 104h and 105i, the spout f is formed.

This type of paper pack has the above-mentioned shape in order to maintain the storage capacity to some extent by returning the external shape to the state before the opening even after the opening. The surfaces 102a and 103b and the corresponding pouring spout constituting surfaces 102a and 103b are in close contact with each other by means such as adhesion, pressure bonding, and welding. In order to open this, it is necessary to peel both. In the actual procedure, first, the pour spout constituting surfaces c and e which are closed in FIG. 7 (A) and the rear root parts j and k are pulled open in the directions of the gripping arrows 111 and 112, respectively. The spout-portion-constituting surfaces 102a and 103b protrude until they form substantially one plane with the other spout-portion-constituting surfaces c, d and e. Then, in order to separate the pour spout constituting surfaces 102a and 103b that have come out to the above positions from the head sandwiching surfaces 104h and 105i, respectively, the spout spout constituting surfaces c and e are pushed backward. As a result, while the pour spout constituting surfaces 102a and 103b are stretched, the head sandwiching surfaces 104h and 105i are compressed from both sides, or are left as they are. Difference occurs and peeling is promoted. Finally, insert a nail or the like into the spout-portion constituting surfaces 102a and 103b that are about to be peeled by and pull in the direction of arrow 113, or pull the spout-portion constituting surfaces 102a and 103b from the outside and pull. The desired size of f is obtained.

[0005]

[Problems to be solved by the device]

 However, in such a conventional example, when the spout-portion-constituting surfaces 102a and 103b are peeled off from the head sandwiching surfaces 104h and 105i, respectively, the adhesion (adhesion, pressure bonding, welding) is too strong. In many cases, it is difficult to peel off due to reasons such as. If it is forcibly peeled off as it is, the surfaces 102a and 103b forming the spout will be broken, which will cause inconvenience when pouring out and the sealing condition when re-storing the contents will deteriorate. Many of these paper packs usually have a large capacity for beverages, and as described above, many of them are intended to be re-stored for the residual material for a certain period of time.

[0006] Further, when it is determined that peeling is difficult so as not to break, by inserting a nail or the like between the pour spout constituting surfaces 102a and 103b and the head sandwiching surfaces 104h and 105i, and pulling it toward you. Although a method of peeling by creating a gap may be considered, it is not hygienically preferable to bring a foreign substance into contact with the portion that will be the spout.

Further, assuming that the above problem may occur depending on the product, in order to facilitate the unsealing, the pouring port constituent surfaces 102a and 102e and the portion diagonally located on the cross section of the quadrangular prism are separated diagonally. Therefore, there are some cases in which opening is recommended.

Usually, when only the spout f is opened and used, if the appearance is returned to the state before unsealing, the folded habit remains on the paper, so a certain degree of sealing is secured, but an example of separating it in the diagonal direction above Then, even if the opening is too wide and the appearance is returned to the state before opening, it will open immediately and it will not be possible to secure the airtightness.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a beverage paper pack having a simple structure and capable of easily and reliably opening a substantially complete spout.

[0010]

[Means for Solving the Problems]

 According to the present invention, in order to solve the above-mentioned problems, one end of a quadrangular prism is a flatly folded bottom part, and one of two facing sides of the head opposite to the bottom part is a central part. The head fold sides (2, 3) are folded back to the outside and the fold points (6) touch each other, and the required inner width is the head fold surface (2A, 2A, 3B), the other side of the head is a side of the head (4, 5) that sandwiches the folding side of the head when closed, and the required inner width is It is a head folding surface (4H, 5I) for adhering to the head folding surface (2A, 3B), and the head folding surface (4H, 5I) is the head folding surface (2A, 3B). By folding inward while sandwiching, the roof part (J, K) connected to the head folding surface (4H, 5I) forms a roof shape, and when it is opened, it is sandwiched by the roof part. The drawer part (6G), which is the surface near the turning point (6), is pulled out to allow the contents to be spouted (F) between the folding sides (2, 3) and the sandwiching sides (4, 5). The following means were employed in the beverage-filling paper pack (1) for forming a beverage.

[1] That is, the beverage paper pack is characterized in that the drawer portion (6G) has a knob (7) for opening. [2] At this time, the knob may be an integrally molded product with the drawer portion (6G), or [3] an accessory that is separate from the drawer portion (6G). [4] Further, in the above [2] and [3], it is desirable that the knob is folded so as to be sandwiched between the drawer portions (6G) when closed. . [5] It should be noted that the number of the lead-out portions (6G) provided with the knobs may be two instead of one.

[0012]

[Action]

 In the paper pack as shown in FIGS. 1 and 7, it is important to surely separate the head folding surface and the head clamping surface. According to the invention of [1], the knob (7) is provided. Reliable peeling can be easily achieved by adding. [2] In this case, if the knob is formed integrally with the drawer portion (6G), the step of adding the knob is not necessary in the production of the paper pack, and as described in [3], According to the method of attaching the add-on to the drawer (6G), the invention can be achieved by simply adding a knob to the existing paper pack design. [4] Furthermore, if the knobs are foldable so as to be sandwiched between the surfaces of the spout when closed, regardless of whether they are added separately or not, they can be displayed or packaged. It does not get in the way and folds downward when pouring the contents, so it does not interfere with pouring. [5] If the number of the pull-out portions (6G) provided with the knob is not one but two, the operation is the same, but the opening can be performed by utilizing the above function on either side.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. [Embodiment 1] FIG. 1 is a development view of a pull-out knob 7 portion of a paper pack of this embodiment, and FIGS. 2A to 2C show a flow of opening the paper pack 1 of this embodiment. is there.

Since this paper pack 1 encloses beverages such as milk, juice, oolong tea, sake, etc., one cut end of a paper-made square pole whose both ends are open is flatly folded to form a bottom surface, and then, still open. The beverage is filled from the side where it is closed, and is folded and sealed in a roof shape at a predetermined distance from the bottom surface.

In this roof shape, the pair of opposite sides of the other cut end of the square pole are folded outward at the central portion so that the respective folding points 6 are in contact with each other, and the head folding sides 2, 3 In addition, the inside is used as the head folding surfaces 2A and 3B so as to serve as a sealing margin when sealing, and the remaining two sides are sandwiched between the head folding sides 4 and 5 so as to sandwich the head folding side at the time of closing. Further, the inner side is head folding surfaces 4H and 5I for adhering to the head folding surfaces 2A and 3B, and the head folding surfaces 4H and 5I fold the head folding surfaces 2A and 3B inward. By sandwiching it while sandwiching it, the roof portions J and K connected to the head folding surfaces 4H and 5I form a roof shape.

The paper pack 1 is sealed by the inner surface of the spout-portion constituting surface 2A and the inner surface of the head clamping surface 4H, and the inner surface of the spout-portion composing surface 3B and the inner surface of the head clamping surface 5I. Attach and complete. At this time, it suffices to bond only the inner surfaces, and it is not necessary to bond the spout forming surfaces 2A and 2B.

In the present embodiment, one or both of the surfaces to be bonded are adhered by applying an adhesive, but the other adhering method may be a film or the like which is sensitive to pressure or heat on the inner surface of the paper pack in advance. It is conceivable that the paper pack itself may be covered or a material that is sensitive to these may be used, and then pressure or heat may be applied to bond them. The present invention is not affected even if the paper pack adopts any of the adhesive, the pressure bonding, and the welding.

A knob 7 is integrally provided on the spout-portion constituting surfaces 2A and 2B so as to extend over them. When the knob 7 is sealed, the knob 7 is folded inward at the folding point 6 and is sandwiched between the 104A and 105B as shown in FIG. 2 (A). At this time, only the inner surface of the knob 7 is bonded to the inner surfaces of 104A and 105B, similarly to the spout-portion constituting surfaces 2A and 2B.

[Opening Flow of Embodiment 1] The opening procedure is as follows. First, pull the opening portions constituting surfaces C and E, which are closed in FIG. The surfaces 2A and 2B forming the spouts are separated from each other, and the folded knob 7 is also opened. Then, when the opened knob 7 is pulled in the direction of the arrow 12, the pouring port constituting surfaces 2A, 2B integral with the knob 7 are separated from the 104A, 105B, respectively. Finally, the desired size of the spout F is obtained by further pulling the spout-portion constituting surfaces 2A and 2B that have been peeled off.

[Knob 7 of Embodiment 1] As the knob 7 used in this embodiment, an example of the knob 7 integrated with the spout-portion constituting surfaces 2A and 2B was first shown, but the knob 7 is not limited to this and is not limited to this. You may use what attached the piece of paper (or the thing of a film form). Fig. 3 shows a developed view of an example with a piece of paper attached (two knobs). The sticking may be performed on the outer surface or the inner surface of the pouring spout constituting surfaces 2A, 2B, or in the form in which the base portion of the knob 7 is embedded between the paper layers of the portion.

[Embodiment 2] FIG. 4 shows a second embodiment of the present invention, which is an example in which the knob 7 is folded so as to be sandwiched between the surfaces forming the spout when the knob 7 is sealed. .

The present embodiment is different from the first embodiment in the knob 7, and only the difference in the opening procedure will be described. [Opening Flow of Embodiment 2] In FIG. 4 (A), the spout-portion constituting surfaces C and E are already open to both sides. At this time, the knob 7 is only folded downward, and is not adhered to anywhere. Then, the knob 7 is slightly lifted in the direction of the arrow in order to make it easier to grip. Next, when the knob 7 is pulled in the direction of arrow 14 as shown in FIG. 4B, the spout-portion constituting surfaces 2A and 2B integral with the knob 7 are peeled off from the 104A and 105B, respectively. Finally, the desired size of the spout F is obtained by further pulling the spout-portion constituting surfaces 2A, 2B separated by the direction of the arrow 15. After that, the knob 7 may be bent in the direction of arrow 15 so as not to hinder the pouring of the contents.

[Knob 7 of Embodiment 2] As the knob 7 used in this embodiment, an example of a knob integrated with the spout-portion constituting surfaces 2A and 2B is shown first. It is not limited to the integral one, and a separate piece of paper or film may be attached to the outer surface or the inner surface of the pour spout constituting surfaces 2A and 2B, or may be embedded between the outer surface, the inner surface and the paper layer.

FIG. 5 shows an example in which separate tape-shaped knobs (made of paper or film) are attached. The tape-shaped knob 7 of this embodiment is fixed to both ends of the tape-like knob 7 so as to straddle the surfaces 2A and 2B constituting the spout. As shown in FIG. 5 (A), the center of the tape-like knob 7 has already come off from the pouring port forming surfaces 2A, 2B near the position where the pouring port constituting surfaces 2A, 2B become one plane. Picking up the part, pull it in the direction of the arrow 16, and perform the opening operation similar to the above-mentioned embodiment.

[Influence of manufacturing process on the type of knob] As a process of actually enclosing a beverage in a paper pack used in the present invention, a mass production effect is sought, and as shown in FIG. Prepare a square column of paper with a length that is an integral multiple of the pack and the bottom part of which is already folded flat.After filling a specified amount of beverage, set a predetermined distance from the bottom part and fold and bond the head part. A step of cutting (when the length is multiple times) may be considered.

Therefore, the tongue-shaped knobs 7 as shown in FIG. 4 and the tape-shaped knobs 7 as shown in FIG. 5 are previously attached to the long rectangular paper poles with the tape-shaped paper pieces 7 ′ at regular intervals. It is possible to deal with this by incorporating the method mentioned above into the above steps.

[0027]

[Effect of device]

 ADVANTAGE OF THE INVENTION According to the present invention, the disadvantages of the conventional square-pillar-shaped roof-shaped beverage paper pack, such as tearing around the spout and excessive opening, are solved. However, by using a paper pack that can open the spout easily and surely, it will be possible to fully exercise the original functions of the paper pack, such as re-storing. .

In addition, the structure in which a separate knob is added to the surface of the spout is adapted to mass production.
