Description

The opening structure on spout of Blister package}

The present invention relates to a discharge opening and closing structure of a blister package for expanding a plastic surface to create a predetermined space and filling a drug or other product into the space, and more specifically, to a discharge portion of a container. It constitutes a bending guide groove that induces a bending point in the lateral direction, and the outer surface of the cover paper, which is adhered to the flange of the container and functions as a sealing function, is composed of a uniaxial stretched film and coincides with the bending guide groove among the uniaxial stretched films. On the line, the incision of the cover paper is to give a straight cut line to guide the discharge part in a straight line. As the above structure is applied, it causes soil and environmental pollution and generates environmental hormones harmful to living organisms. Instead of applying hazardous materials, eco-friendly materials that are harmless to humans or the environment The portion cut for discharging the contents is limited to a thin back cover that covers the opening of the discharging portion, and the hard discharging portion is simply bent so that the cut portion of the cover sheet is rotated based on the discharging portion when the contents are bent. It allows the product to be contacted to the original position without change, thereby improving the sealing property of the contents and improving product differentiation and consumer reliability.

In general, a blister package is a kind of packaging method as a thermoplastic plastic film or sheet, and a mold made according to the shape of the product to be packaged is installed in a molding machine, and the blown or blown plastic film or sheet formed by vacuum forming is formed. It is widely used in the packaging of daily necessities, general merchandise, tablets, cosmetics, etc. as a method of heat-sealing or adhering only the flat part (flange part) of a molded film or sheet after putting contents or a product in a part. .

Meanwhile, the liquid, cream, or waxy contents such as cosmetics are also packaged using a blister package, and the blister package applied to the blister package is composed of the same material as the container in the manufacturing process at one end of the melted container having an arbitrary shape. If necessary, the discharging part in the form of a short pipe configured to open the inside to discharge the contents is kept in communication. The edge of the container is composed of a flat flange, but the container opening can be sealed by covering the opening of the container with the opening of the container. It is a constitution that the adhesive cover composition for sealing is composed of a multi-layer so that.

However, the conventional structure of the blister package having such a basic configuration has a perforation line extending to both ends of the flange portion in a state transverse to the discharge portion of the molded plastic film or sheet, and is discharged by folding the perforation line when the contents are taken out. As the cutting part is opened, the inlet is opened to draw out the contents. In order to easily cut the discharge part by bending, it is necessary to apply a material with less elongation and flexibility due to the characteristics of the material constituting the discharge part. Polyvinyl chloride (hereinafter abbreviated as PVC) or polystyrene (hereinafter abbreviated as PS) were applied to the material forming the discharging part with these materials. There is no problem, but in the former, unreacted monomers are carcinogenic substances in manufacturing. In case of disposal and incineration, the plasticizer produces dioxin, an environmental hormone, which is gradually regulated in the food or cosmetics industry. The latter decreases the reproductive function of ecosystems and humans with extremely small amounts during disposal and incineration. · It is known to be a substance that generates environmental hormones that have a significant effect of causing growth disorders, malformations, and cancers, and it is a serious problem.

On the other hand, the amount of the contents contained in the container may be consumed all at once, but most of them have an amount to be used many times, so that the part cut to act as a stopper after opening the discharge part still needs to be connected.

However, in the structure of cutting the conventional discharge part, the hard part constituting the container is kept in the state of being connected by thin uncovered cover paper attached to the flange while being completely cut and separated by the perforation line. When the discharged part cut to the original position is easily moved, the position of the discharged part is easily shifted, and both cutting parts of the discharged part do not match each other and are shifted, so that the closure function is hardly achieved, resulting in the infiltration of foreign matter into the contents, the deterioration and damage. This was to be brought about.

The present invention was devised to solve the above-mentioned problems, and the object of the present invention is to apply to the human body or the environment instead of the application of harmful substance emission material that causes soil and environmental pollution and generates environmental hormones harmful to living organisms. Harmless, eco-friendly materials, such as 'polyester (PET) or polypropylene (PP)' can be applied, and the part cut for discharging the contents should be limited to a thin back cover that covers the opening of the discharging part. The superior discharge part is only bent so that when the contents are reused, the cut part of the cover can be rotated on the basis of the bent discharge part and can be brought into contact with the original position without change, thereby improving product differentiation and improving consumer reliability by improving the sealing property of the content. Blister package for application of environmentally friendly materials (Blister p) to provide an opening opening structure of an ackage,

In order to achieve the above object, the present invention proposes a bending guide groove for guiding the breaking force to be concentrated on the cutting line by forming a concave starting point formed in the discharge portion of the container in the transverse direction.

In addition, the present invention constitutes the surface of the cover paper, which is adhered to the flange of the container as a sealing function as a uniaxial stretched film, and at the same time, the cut portion of the cover paper penetrates the discharge part in a straight line on the line coinciding with the bending guide groove of the uniaxial stretched film. By providing a straight cut line to guide.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view showing the front surface of a blister package to which the present invention is applied, and FIG. 2 is a perspective view showing the back side of a blister package to which the present invention is applied, and FIG. At one end of the melted container (1) having an arbitrary shape, the discharge unit (2) in the form of a single tube formed in the same state as the container in the manufacturing process and configured to discharge the contents by opening the interior as necessary, is in communication. A cover for sealing is formed in a multi-layer so that the edge of the container (1) constitutes a flat flange portion (3), but the opening of the container and the flange portion (3) to cover and seal the opening of the container (1) In the known structure in which the paper 4 is adhesively constituted;

The container 1 and the discharge part 2 is applied to the polyester (PET) film or polypropylene (PP) film harmless to humans and the environment,

In the middle portion of the discharge portion 2 as shown in Figs. 1 and 3 when breaking the cutting line 30 to be described later for the extraction of the contents to the starting point is not cut but only bent to form a starting point of bending to break the cutting line In order to guide so as to be concentrated on the (30), the straight guide groove 10 of the concave configuration in the transverse direction is provided.

In addition, the outermost surface of the cover 4 to be bonded to the container 1 has a uniaxially stretched film layer 20, but the cover paper (4) while going inward from the outermost side as shown in FIG. 20), the adhesive layer 4A, the aluminum foil layer 4B, the polyethylene layer 4C, and the adhesive layer 4D are sequentially formed.

Uniaxial stretching typically improves physical, mechanical, and properties such as stretching monofilaments, films, sheets, tapes, and pipes of thermoplastics to temperatures below their melting point, thereby reducing the thickness of the cross-section or creating molecular orientation. As one product, uniaxial stretching for stretching in one direction, biaxial stretching for stretching in two directions, and multiaxial stretching for stretching in multiple directions,

The material constituting the uniaxial stretched film layer 20 of the present invention may be a polyester (PET) film, a high density polyethylene (HDPE) film or a stretched polypropylene (OPP) film.

On the uniaxially stretched film layer 20 of the cover paper 4, they are spaced apart from each other only on the other lines except for the portion occupied by the opening of the discharging portion 2 and facing the forming line of the bent guide groove 10. Consists of a straight line to form a set of cutting line 30 for guiding guide so that the cut portion can pass through the discharge portion (2).

In the above, the uniaxial stretched film layer 20 is positioned so that the stretching direction coincides with the longitudinal direction of the cutting line 30 and pulls in a direction perpendicular to the cutting line 30 in the non-stretching direction.

The present invention configured as described above is to fill the contents by using a packaging machine for a blister package known in the art. In order to withdraw the contents, the user cuts both sides of the cut line 30 with both hands as shown in FIG. 3. If the bending direction (30) in the direction of the arrow is bent in the state that the upper part of the cutting line 30 is bent in the contracted state while being rotated to the starting point of the bending guide groove 10 as in the imaginary line in the opposite direction to the cutting line 30 line The tensile force is applied and pulled, and when the bending force is applied, the bending guide groove 10 is bent first, so that the bending force applied to the cover 4 is not dispersed to other portions, but on the perforated line 30. It has the effect of concentrating so that the fractured part of the discharge part 2 is always constant.

The direction in which the tensile force of the line of the perforated line 30 is applied corresponds to the non-stretching direction of the uniaxial stretched film layer 20, and is a direction in which the tearing force does not increase when pulled.

Therefore, the portion of the cutout line 30 that is already formed in the entire thickness of the uniaxial stretched film layer 20 or is formed to the depth of most of the thickness is much less easily resisted against external force than the portion without the cutout line 30. The uniaxial stretched film layer 20 in the portion fractured and occupied by the opening of the ejection portion 2 which did not form the tear line 30, although the uniaxial stretched film layer 20 was stretched even though the cut line was not processed. Since it coincides with the non-stretching direction of, it is easily broken so that the ejection part 2 can be opened to take out the contents.

If it is necessary to prevent the discharge part opened for reuse after the withdrawal of the contents in the above, if the bent part is flipped back to its original position, the fractured parts of the cover paper 4 are rotated on the basis of the discharge part 2. It is designed to seal the contents in contact with each other, and the container side with excellent rigidity is cut and the cover side with weak rigidity is left, so that the return force to the exact original position is weak and the sealing property is insignificant. Since the relatively rigid container side remains and the weak cover side is broken, the sealing property can be improved through the accurate return force to the original position when sealing for reuse.

On the other hand, the reason why the cutout line 30 is formed to be spaced apart in the state except the portion occupied by the opening part of the discharge part 2 is that if the cutout line is completely formed to the part occupied by the opening part of the discharge part 2, it is transported or handled. This is because the cover paper 4 is easily broken even in a small external force, which may cause unauthorized leakage of the contents.

The present invention as described above can be applied to environmentally friendly materials that are harmless to humans or the environment, instead of the material that emits harmful substances, can prevent the pollution of the environment, and when the contents are reused, the cut portion of the cover sheet is returned to its original position without any change. It is possible to improve the sealing property of the contents by allowing them to come into contact with each other, thereby having the effect of improving product differentiation and consumer reliability.
