INVENTION The present invention relates to a package sealing the periphery thereof overlapping the film, in particular to the opening structure of the package encapsulating the orthopedic material.

[0002] The films were sealed around the superposed packaging body has been used in various fields, in order to utilize what is sealed inside must open the package. Although the opening may be used a cutting tool such as scissors, the film package is a significant advantage of the one being able to tearing open by hand directly.

In the field of medicine, a hydraulic cast material in which a urethane prepolymer is applied to a base cloth is used as an orthopedic material, but this cast material hardens when exposed to moisture in the air. Stored tightly in a packaging bag and opened for the first time when used. This cast material contains a tack-free agent so that it does not stick to the hand when it is rolled around the affected part by hand, but since it is not completely tack-free, it is often operated with gloves. However, after handling one cast material, the next packaging
When the body is to be opened, the tack-free agent adheres to the glove in the previous operation, so that the glove becomes slippery, so that there is a problem that the glove cannot be easily opened. In order to solve this point, in order to reduce the tear strength of the packaging material, reduce the thickness of the packaging material, use a directional material,
Attempts have been made to increase the depth of the cuts provided at the tearing points, but storage stability (durability) has been reduced, or sufficient ones have not been obtained. For this reason, it is necessary to use knives and scissors for opening.

SUMMARY OF THE INVENTION An object of the present invention is to facilitate opening of a film package in which a hydraulic cast material is enclosed by tearing.

[0005]

In order to achieve the above-mentioned object, in the present invention, a notch is formed on a sealing side of a film package in which a hydraulic cast material is enclosed, and a tip of an index finger is provided on both sides of the notch . Thickness of fingertip over half of abdomen
It is intended to provide a through hole having an area of up to.

[0006]

[Function] In the present invention, at the time of opening, a finger is applied to the through hole to apply a force in a tearing direction along the cut, so that even if moisture, tack-free agent or the like is attached to the glove,
Since the frictional resistance between the glove and the film surface is large, the glove can be reliably opened without slipping on the film surface.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In FIG. 1, reference numeral 1 denotes a package , which is formed by stacking films and sealing the periphery 2 thereof, and one of the sealing sides 3 thereof.
Are provided with holes 5 and 6 penetrating the seal sides on both sides with the notch 4 interposed therebetween. Hydraulic cast material is sealed coated with a urethane prepolymer comprising a water soluble tack-free agent base fabric during this packaging.
This package to be opened by adding the tear strength across the through holes 5, 6 in the thumb and index finger of the right and left hands, respectively, the film is torn in the extending direction of the cut 4.

FIG. 2 shows various examples of the shape of the notch 4, in which A is a V-shape, B is a U-shape, C is a straight type, D is a combination of a V-shape and a straight line, and E is a V-shape and a broken line. F is a broken line type.

FIG. 3 shows various examples of through holes 5 and 6, wherein A is a circle, B is a horizontally long oval, C is a vertically long oval, D is a square, E
Is a triangle and F is a rhombus. Combinations having different shapes and sizes of the left and right through holes may be used.

FIG. 4 shows the positional relationship between the notch tip and the through hole, and is an example of a combination of a V-shaped notch and a circular through hole. Cuts a is 'located in a zone, cuts b is b between the upper end 8 and the center 9 of the through-holes' a between the upper end 8 of the outer edge 7 of the package through hole located in a zone,
The notch c is in the c 'zone between the center 9 and the lower end 10 of the through hole, and the notch d is in the d' zone below the lower end 10 of the through hole. A <b
<C <d and d are most likely to be torn, and a and b have a notch of c or more, since it is difficult to tear ahead when the tear line reaches the through hole. Note that the notch tip means the tip of a straight or broken line in the examples of FIGS. 2D, 2E, and 2F.

FIG. 5 shows various examples of the positional relationship between the cuts and the through holes, where p and p 'are the outer edges 7 of the package , respectively.
, The distance between the center 11 and the center 12 of the through holes 5 and 6, q and q ′ are respectively the center line 13 of the cut and the center 1 of the through holes 5 and 6.
Shows the distance to 1 and 12. A is p = p ', q = q', B is p = p ', q ≠ q', C is p ≠ p ', q
In the case of = q ', D can be any of p ≠ p' and q 、 q ', but the most symmetrical case of A is most preferable.

Although the size of the through hole depends on the size of the package and the width of the seal, it is preferable that the through hole has an area of at least half of the abdomen at the tip of the index finger. Can be grasped.

As the film material of the packaging bag, various materials can be used. For example, polyester / aluminum / polyethylene / linear low density polyethylene, K nylon / aluminum / polypropylene, polyethylene /
Polyvinylidene chloride / polyethylene, polyethylene / K
There are multilayer films such as nylon / polyethylene.

Next, an example of a method for manufacturing the packaging bag of the present invention will be described with reference to FIG. 61 and 62 are film rolls,
Then, the film strips 63 and 64 drawn out are superimposed on guide rolls 65 and 66 and heated rolls 67 and 68.
6A, and along both sides as shown in FIG.
9, 610. Next, the heat seal plate 611 is used so that the seal
12 and guided to a die cut roll 613, where a cut 614, two through holes 615, 616 are made and cut 617 from the film strip to obtain a packaging bag 618 as shown in FIG. 6C. In this packaging bag 618, a hydraulic cast material is sealed from the opening 619, and the opening 619 is sealed.

[0015]

According to the present invention, the provision of the through-hole causes a large coefficient of friction for the finger gripping the through-hole, and in some cases the finger can be hooked on the through-hole. Even if the hand or glove worn on the hand is wet and slippery with water containing tack-free agent when handling hydraulic cast material containing, the package is securely held and sufficient tearing force against cuts is obtained. It can act, it is possible to open the film package easily,
Orthopedic materials can be handled smoothly.
