Description

  The present invention relates to a packaging container.

  A refill container (an example of a packaging container) such as a standing pouch is generally formed of a laminated film based on the following resin film.

  The laminated film forming the refill container includes NY (nylon) / AL (aluminum) / PE (polyethylene), NY / PET (polyethylene terephthalate) vapor deposition / PE, and NY / PE in order from the surface.

  With respect to the packaging container, for example, as disclosed in Japanese Patent Application Laid-Open No. 2003-137310 (Patent Document 1), an upper portion of the standing pouch is provided with a pour-out portion for refilling at a planned opening position (breaking portion). Are subjected to laser machining, machining with a blade, etc., electrical discharge machining with corona discharge or plasma discharge, or easy opening with a heat bar or the like.

  In addition, there is a case where a picking part for opening is formed on the tip side of the breaking part, and embossing is performed so that the picking part is difficult to slip even if the fingers are wet when refilling in a bathroom or a bathroom. And knurling. A similar technique is disclosed in Japanese Patent Laid-Open No. 2005-132429 (Patent Document 2).

  However, in the disclosure techniques of Patent Document 1 and Patent Document 2 described above, the easy opening process and the knob part are broken at the planned opening position due to a drop impact or interference between products that occurs during handling such as production process, transportation or store display. As a result, leakage of contents may occur, and other products may be soiled or the surroundings may be soiled, and improvements have been desired (referred to as “basic issues”).

  Further, as a conventional technique for preventing damage to other articles at the corner portion of the notch at the opening position, there is one in which a circular punching portion is formed on the I-shaped notch of the opening start portion of the heat seal portion (Japanese Patent Application Laid-Open No. 2005-260707). 2005-247348 gazette: patent document 3). Of these, punching merely increases the visibility of the opening, and circular punching does not stop cutting.

  Also, there is a technique in which a cut-off slit is provided in a direction intersecting the tear line at the seal notch part formed at the seal part on one side of the pouch and the tear line (open line) (JP-A-7-69370). No .: Patent Document 4).

  However, in the cut-off slit of Patent Document 4 formed as described above, when the user picks the knob and tears the easy-opening part to perform the opening operation, the opening line stops at the punching part or slit, but the punching The direction of opening from the part or slit cannot be controlled, and there is a problem that the opening line or tear line extends in an unintended direction.

  On the other hand, in Japanese Patent Application Laid-Open No. 2000-109097 (Patent Document 5), an easy tearing process such as a notch is performed on the edge of the seal portion, and a V-shaped defect portion is formed by cutting into the seal portion on the inner side from the edge of the seal portion. A technique for facilitating tearing and opening with a bare hand is disclosed. However, with this technique, when the tear line reaches the defect portion contrary to the intention, the opening easily proceeds, so the basic problem cannot be solved.

  Further, in Japanese Patent Laid-Open No. 2003-276744 (Patent Document 6), the notch and the opening assisting line are formed discontinuously, and the portion near the tip of the opening assisting line on the notch side is formed in a different direction from the force applied to the notch. ing.

However, in the technique described in Patent Document 6 described above, when the tear line extends from the notch to the opening assisting line with an unintended force, it is easily opened from there, so the above basic problem is solved. It is not possible.

  The present invention has been made to solve the above-described conventional problems, and even if a drop impact or interference between products occurs when handling a packaging container, a picking portion such as a picking portion or a position to be opened is provided. It is intended to provide a packaging container that is easy to open at an appropriate force when opened by a consumer, and the easy-open portion formed in the box is not easily broken.

The present invention relates to a packaging container.
In the present invention, a container is formed by welding or bonding a peripheral portion with the film portion including at least one layer of a resin film being stacked, leaving the central portion, and the contents are placed in the internal space of the central portion. A packaging container that is sealed after filling,
In the pouring part for pouring the filled contents to the outside, an easy-opening part that allows the user to tear and break more easily than other parts with fingers is provided in a line,
A break starting portion that can be easily broken by the fingers is provided discontinuously on the easily opened portion on the peripheral edge of the packaging container that is welded or bonded,
Between the rupture start portion and the easy-open portion in the peripheral portion, a rupture interference portion is provided on the imaginary line connecting the rupture start portion and the easy-open portion to stop the break from the rupture start portion. It is a packaging container.

  In the present invention, it is preferable that the fracture interference portion is discontinuous with the fracture start portion and the easy-open portion.

  Moreover, in this invention, it is suitable for the fracture | rupture interference part to provide the punching part which spreads in the orthogonal | vertical direction to the virtual line which connects a fracture | rupture start part and an easy-opening part. In this case, the fracture interference portion may be any punched portion such as a straight shape, a rectangular shape, a polygonal shape, or a circular shape.

  Further, in the present invention, after the breakage proceeds from the break start part and reaches the break interference part, when the breakage further proceeds, the break toward the easy opening part is directed toward the easy opening part so that the break converges toward the easy opening part. It is preferable to provide a guide part. One or more fracture interference portions can be provided.

  Further, in the present invention, the break interference part is a linear part extending in a direction perpendicular to the imaginary line connecting the break start part and the easy opening part, and is directed from the both ends of the linear part part to the easy opening part. It is preferable that the extended guiding portion is formed in a substantially U shape.

  According to the packaging container of the first to fourth aspects of the present invention, between the break start portion and the easy opening portion at the peripheral portion, the break start portion on the virtual line connecting the break start portion and the easy open portion. Because the break interference part that stops the break is provided, even if the packaging container product falls or breaks from the break start part due to interference between products, the break interference part stops the break and does not advance further. At the same time, the consumer can provide a packaging container that can be easily opened by the easy-opening portion as long as the breaking interference portion is broken.

  In the present invention, if the fracture interference part is discontinuous with the fracture start part and the easy-opening part, the fracture does not easily proceed from the fracture start part to the fracture interference part, and the fracture can be prevented from further progressing.

  Further, in the present invention, if the fracture interference portion is provided with a punching portion that extends in a direction perpendicular to the imaginary line connecting the fracture start portion and the easy-opening portion, the fracture interference portion more effectively stops the fracture. In addition to being hard to cut, it is easy to form because it is punched.

  Further, in the present invention, after the breakage progresses from the break starting part and reaches the break interference part, when the breakage further proceeds, the induction toward the easy open part so that the break converges from the break interference part toward the easy open part. If the user picks around the rupture start portion of the packaging container with his / her fingers and applies a force that pulls the force in the tearing direction, the rupture is temporarily stopped at the rupture interference portion. As a result, the break line is surely guided to the easy-opening portion by the guide portion, and no erroneous break occurs.

  The breaking interference part is a linear part extending in a direction perpendicular to the imaginary line connecting the breaking start part and the easy opening part, and the guiding part is directed from both ends of the breaking buffer part of the linear part toward the easy opening part. It is preferable that the rupture interference part and the guide part are formed in a substantially U shape so that the guide part can be formed with a simple shape.

Body products.

The film-like body is composed of at least one laminated film, for example, NY (nylon) / AL (aluminum) / PE (polyethylene; including low density polyethylene, medium density polyethylene, high density polyethylene), NY / PET in order from the surface. (Polyethylene terephthalate) vapor deposition / PE, NY / PE. In this case, the innermost resin layer is PE, and the innermost layer is PE.
Resins having high sealing properties with respect to contents such as EVOH (ethylene vinyl alcohol) and PAN (polyacrylonitrile) are preferable materials, and these can be used as a film uniaxially or biaxially stretched. Further, the layer adjacent to the innermost layer, that is, the adjacent layer is not particularly limited, and the adjacent layer can be laminated on the innermost layer via an adhesive. For example, the same or different resin agent as the innermost layer is used. In addition to a vapor-deposited layer of metal, metal oxide or silicon oxide, a paper layer, a cellophane layer, or the like can be appropriately formed.

  The packaging container 10 can be formed by folding the film-like body in two and combining two or more sheets into an approximate shape, and then welding (heat-sealing) the peripheral edge portion 10b. If there is no problem in strength and leakage resistance, bonding is also considered.

  In the case of a four-side sealed bag, the two film-like bodies on the front and back sides are unwound from an unwinding roll, and the left and right sides of the peripheral portion 10b of the two film-like bodies are heat-sealed by a side seal device and the bottom is heat-sealed by a bottom seal device. .

  In the case of a three-sided seal bag, the film-like body is unwound from a roll, bent, and side-sealed.

  Further, in the case of a standing pouch, the outer shape is adjusted, and a fracture start portion 16 such as a notch described later and a fracture interference portion 20 such as a hole described later are formed in the peripheral portion 10b by punching. The packaging container 10 subjected to the punching process is filled with contents, and then the top part is heat-sealed to be a product.

  FIG. 1 shows an example of a standing pouch. The bottom part is side-sealed in a folded state with a folding gusset, and the filling part 12 side is heat-sealed after filling the contents.

  In 1st-3rd embodiment shown in FIGS. 1-6, the boundary of the welding site | part (heat seal) of the peripheral part 10b and internal space is shown with the broken line 10c.

  In the packaging container 10, a pouring part 12 for pouring the filled contents to the outside is formed in the upper part, and in the product packaging container 10, the pouring part 12 is blocked by welding. It is peeling off. Specifically, in the extraction part 12, an easy-opening part 14 that can be easily torn and broken by the user with fingers is provided linearly. The easy-open portion 14 can be easily torn and opened when it is torn by thinning it linearly or omitting printing.

  Further, on both the left and right sides of the welded peripheral edge portion 10b of the packaging container 10, a break start portion 16 that can be easily started to break by the fingers is provided discontinuously in the easy opening portion 14, and the peripheral edge portion 10b Between the rupture start portion 16 and the easy-open portion 14, a rupture interference portion 20 that stops the break from the rupture start portion 16 is provided on a virtual line 18 that connects the rupture start portion 16 and the easy-open portion 14. ing.

  In the first embodiment, as shown in FIGS. 1 and 2, the fracture start portion 16 is a slit-like or straight notch 16A from the outer edge of the peripheral edge portion 10b.
