Description

Safe plastic bag opening mechanism {SAFETY VINYL PACK OPENER}

The present invention relates to a plastic bag opening mechanism for easily opening a sealed plastic bag with contents, such as a pouch containing herbal medicine and various juices or a synthetic detergent for refilling, and particularly, before and after cutters in a guide space into which plastic bags are put. The left and right sides have an open structure so that the bag is not caught, and the cut bag can be prevented from being caught by the body portion thicker than the cutter, thereby increasing the cutting resistance.

Generally, such as pouches containing herbal medicines and various juices, plastic bags and the like sealed with contents are easy to carry or store, but it is common to use scissors or a knife when opening. However, when using a knife, it is difficult and dangerous to cut straight even for adults, and it is possible to cut straight when using scissors, but it is inconvenient to carry with a plastic bag at all times. If the plastic bag is a synthetic detergent for refilling at home, it is inconvenient to clean the scissors after cutting or prepare several scissors for each use.

The plastic bag opening mechanism has been developed in the past to solve this inconvenience, the prior art is that the open guide space is formed on one side of the main body of the device, the cutter is fixed to the guide space. When cutting the envelope edge by the cutter by inserting a plastic bag into the guide space of the conventional opening mechanism, the sharp part of the corner of the envelope to be cut first is caught by the mechanism body thicker than the cutter thickness, and smooth cutting is not possible. The phenomenon in which the envelope cut by the cutter is caught in the opening mechanism due to the cause is referred to herein as a 'cutting resistance'. In such a conventional opening mechanism, the user often uses excessive force to overcome the 'cutting resistance', so There was a problem of spilling the contents, and even the user of the opening device was injured. -0032841 (2002.11.02) has been devised and applied, Another variant is to devise and the Utility Model Application No. 2002-0032841 call.

The object of the present invention is to prevent the occurrence of cutting resistance, as well as to prevent the occurrence of cutting resistance by first cutting the pointed part caught on the body portion thicker than the cutter thickness when the plastic bag opening mechanism is made by a conventional method. In order to prevent direct contact with the injured to form a narrow width of the guide space to provide a plastic bag opening mechanism that is safe to carry with a plastic bag on a daily basis.

In order to satisfy the above functions, the body portion thicker than the cutter can be removed, and the exposure width of the cutter can be set to 2 mm or less.

1 is a perspective view of a plastic bag opening mechanism according to the present invention.

In order to achieve the above object, the plastic bag opening mechanism according to the present invention is designed to cut the plastic bag introduced into the guide space by a cutter fixed between the main body and the safety cap, but the cut bag hits the body thicker than the cutter. In order to prevent the cutting resistance occurs, the guide spaces before and after the cutter have a structure in which the front, rear, left, and right sides of the cutter are open. Hereinafter, the plastic bag opening mechanism according to the present invention will be described in detail with reference to the accompanying drawings. Regarding the directionality in the present invention, as shown by the dashed-dotted magnetic field line in FIG. 1, the direction in which the blades of the cutter 2 face is referred to as the front and the opposite side as the rear. In addition, the upper part of the guide space 4 slightly biased to one side is referred to as the upper side, and the opposite side is referred to as the lower side. The surface shown in Fig. 1 is referred to as the left side, and the opposite side is referred to as the right side. The present invention is distinguished from various cutters in the prior art by being easy to carry and narrowly formed to prevent the user from being injured by the blade. However, the most important difference is that the cutting resistance is naturally removed from the beginning to the end when the envelope is cut by the cutter of the present invention in order to open various plastic bags. As a structure for removing the cutting resistance of such an envelope, the opening mechanism according to the present invention employs a structure in which the guide space 4 is open at the front and rear sides of the cutter 2 except for the cutter 2. In other words, in the present invention, the main body 1 and the safety cap 3 are constituted by separate mechanism members that are separated from each other, and serve to connect the two members. The cutter 2 is formed. A guide space 4 is formed between the main body 1 and the safety cap 3 so that the front, rear, left, and right sides of the cutter 2 are empty, and the fixed cutter 2 When the plastic bag inserted into the guide space 4 is cut, the bag to be cut can be smoothly progressed along the guide space 4 because there is no jamming phenomenon that causes cutting resistance to the rear of the cutter 2. 1) and the protection scope of the present invention should not be limited by the shape and size of the safety cap (3). The shape of the guide space (4) is of course straight, as shown in the front and rear of the cutter (2), of course, the body As long as the guide space between (1) and the safety cap (3) satisfies the structure opened in front and rear of the cutter (2), it is initially straight and then curved upward or downward in the rear of the cutter (2). It is also possible. Therefore, the shape of the guide space 4 does not limit the protection scope of the present invention. On the other hand, in the present invention, the width W of the guide space 4 is prevented from being cut by the cutter 2 while the user is carrying the device. ) Is preferably 2 mm or less, in particular 0.2 to 2 mm.

In the method of manufacturing an apparatus according to the present invention, in addition to the method of bonding after injection, a method of injection molding in a conventional manner after fixing the cutter 2 to a molding die may be used. The left and right sides are smooth to be used as the advertisement surface 5 for producers, sellers and advertisers for various plastic bag products, so that it is preferable to attach or print stickers. Of course, it is also possible to advertise by engraving or embossing in the mold itself.

In the bag opening mechanism of the present invention, the plastic bag is cut by the cutter 2 by holding the main body 1 and passing the edge of the plastic bag into the guide space 4.

Unlike ordinary envelope opening mechanisms, since the cut portions of the envelopes are caught in front and rear of the cutter 2, there are no obstacles that cause cutting resistance. The cutter 2 has an effect of preventing the contents from popping out. The cutter 2 is exposed only by the width W of the guide space 4 by the safety cap 3, and the guide space 4 is narrow so that the cutter ( 2) Since the user's hands or body parts are not in direct contact with each other, it is effective to secure safety without worrying about the veil. Therefore, the function of the safety plastic bag opening mechanism is safe, easy to carry, and easy to use. When the main body 1 is made of synthetic resin, it is light enough and the manufacturing cost is low, and a wide advertising surface 5 is secured on the main body 1, thereby promoting promotion and advertisement. There are a variety of effects that can take advantage of.
