[Detailed description of the invention]

[0001]

The present invention relates to a liquid container.

[0002]

2. Description of the Related Art In general, as a container for storing various liquids such as juice, sake, soy sauce, etc., a Goebel top type container formed of a material obtained by laminating a plurality of PE, Al, paper and the like is widely known. .

FIG. 2 is a perspective view of such a gobel top type container. The container 101 has a body 102 and a gobel top type top closure 103. Torso 102
Are formed by two sets of side plates 104, 104,. And a goebel top type top closure 1
Numeral 03 has a central laminated rib 106 to which the upper ends of the roof panels 105, 105 are superposed and bonded.

[0004] The extraction of the liquid loaded in the container 101 is performed by opening both the opposing roof panels 105 to the left and right, exfoliating a part of the center laminated rib 106, and removing the end panel 1
07 is bent out, so that the upper part of the container is fully opened.

[0005] In the above-mentioned liquid container, the central laminated ribs 106 are heat-sealed with PEs and bonded very firmly. This is used in containers for contents, such as sake, soy sauce, dairy products, etc., especially for long-term storage.

On the other hand, there has been proposed a liquid container in which the anti-heat sealing agent is applied to the entire surface of the sticking portion to reduce the strength of the sticking portion so that the central laminated rib 106 can be easily peeled off. I have. This is effective for contents that do not assume long-term storage such as milk and juice.

[0007]

However, when the central laminated rib is firmly attached as described above, there is no problem such as leakage, but there is a problem that opening is inconvenient. In addition, when applying an anti-heat sealing agent to the entire surface of the sticking part, it is effective for contents that do not assume long-term storage. There are problems such as leakage or decay.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a govel top type liquid container which is easy to open without fear of leakage or the like.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view of a blank plate 1 forming a liquid container according to the present invention on the inner surface side of the container. In FIG. 1, a blank plate 1 has four side plates 2, 2,...
Is provided with an adhesive flap 3 via a folding line b. On the side plates 2, 2,..., Roof panels P ₁ , P ₃ and end panels P ₂ , P ₄ are alternately connected via folding lines c.

The roof panel P ₁ has an inclined panel 4 connected to the side plate 2 via a fold line c, and an outer rib panel 5 connected above the inclined panel 4 via a fold line d. doing.

The wife panel P ₂ has a folding line c on the side plate 2.
, A pair of folded panels 7, 7 connected to the folding panel 6 via folding lines e, e, and a folding line to the folding panels 7, 7. d) a pair of inner rib panels 8, 8
And

The roof panel P ₃ and the wife panel P ₄ have the same configuration, and are denoted by the same reference numerals in the drawings, and detailed description will be omitted. In the blank plate 1 thus configured, an anti-heat-sealing agent 12 is applied near the fold line d, except for the fold lines a, near the inner rib panels 8, 8, of the end panel P2. Further, a folding line a vicinity of the inner rib panels 8,8 wife panel P _4, except for the portion where the adhesive flap 3 at the time of forming the central laminated ribs polymerized, also the fold line d side nearer anti Heat The sealant 13 is applied. Here, the reason why the anti-heat sealing agent 13 is not applied to the portion where the adhesive flap 3 is superimposed at the time of application and the vicinity of the portion where the adhesive flap 3 is superimposed is that a step portion is formed at the boundary portion by the adhesive flap 3, This is to ensure the adhesion of the step and prevent the adhesion failure. Thereby, the bonding of the step portion by the bonding flap 3 is made strong.

Hereinafter, a case where the liquid container is assembled will be described. First, fold line a and fold line b are folded,
The adhesive flap 3 is superposed on the side plate 2 on the other end side, and heat-sealed. The carton attached to the body is raised into a rectangular tube shape to form a known bottom. After the contents are filled, the folding panels 6 and 6 of the wife panels P ₂ and P ₄ are folded inward along the folding line c. At the same time, fold line e
Are folded in such a way that the folding panels 7, 7, ... are folded. Then, the inclined panels 4 and 4 of the roof panels P ₁ and P ₃ are thereby folded inward. On the other hand, the inner rib panels 8, 8,... Are sandwiched and sandwiched by the outer rib panels 5, 5. As a result, a center laminated rib is formed. When heat-sealing is performed in this state, the portions where the anti-heat-sealing agents 12 and 13 are applied are in a form in which the portions of the anti-heat-sealing agents 12 and 13 and a normal PE layer are polymerized. Becomes In places where the anti-heat-sealing agent is not applied, sealing is performed firmly. As a result, in the central laminated rib portion, the position of the temporary attachment state and the position of firmly sealing coexist, and when the inner rib panels 8, 8 are peeled from the outer rib panels 5, the provisional attachment is performed. The outer rib panels 5 and 5 are peeled off while being easily separated.
Since the release agent is not applied to all of the layers, all the portions in contact with the outside of the central laminated rib are in a strong adhesion state of the PE layers, and leakage can be reliably prevented.

The layer structure of the blank plate 1 in this embodiment is PE / paper / PE / Al / PET /
PE.
