Description

  The present invention relates to a synthetic resin bag body in a form in which a palm portion extending from a body portion of the synthetic resin bag body is used as a content outlet.

  In a packaging bag for food, etc., as shown in FIG. 4 (a), gusset films 4 are interposed on both sides between two body films 1a and 1b on the front and back sides, and the body films 1a and 1b are sealed. There is provided a synthetic resin bag body with a horizontally-arranged three-dimensional joint portion in which the joint portion extending further and standing upright at the center of the upper surface of the body film 1a, 1b is 3 as a content outlet. Further, as shown in FIG. 4 (b), a horizontal portion 3 extending from the front and back body film 1a, 1b and standing upright at the center of the upper surface of the body film 1a, 1b is used as a content outlet. There is provided a synthetic resin bag body with a flat-type joint.

  In this synthetic resin bag with a palm portion, the palm portion that becomes the opening always has elastic recovery in the closing direction, so it is difficult to avoid the bag mouth becoming narrow at the time of opening. There was a problem that it was difficult to remove smoothly.

In addition, in order to prevent discoloration, quality deterioration, and oxidative deterioration due to light such as ultraviolet rays or fluorescent lamps, the body films 1a and 1b are colored light-shielding films. Therefore, the contents are removed from the outside of the bag body. It was impossible to see through, and there was an inconvenience of taking out an amount of contents more than necessary in advance and returning the excess takeout into the bag.

  This invention is providing the synthetic resin bag body which improved the convenience to a user in the synthetic resin bag body with a horizontal placement type | mold or a flat type palm part.

  According to the present invention for solving the above-mentioned problem, as described in claim 1, the cylinder is configured such that a gusset film is interposed between both sides of the body film between the front and back surfaces, or side sealing is performed without a gusset film. In a synthetic resin bag body with a palm portion that extends from the part film and stands upright at the center of the upper surface of the trunk film, with a palm part, the both sides of the base part of the palm part or in the longitudinal direction of the palm part on one side Along with this, a synthetic resin shape holding tape is applied across the base portion and the body film of the palm portion, and the synthetic resin shape holding tape is maintained in a wide open state when the palm portion is opened. It is what.

  3. The body part according to claim 2, wherein the body part is sealed with a gusset film on both sides between the two opaque front and back opaque body film films, or side seals without the gusset film being interposed. In a synthetic resin bag body with a palm portion that has a palm portion that stands upright at the center of the upper surface of the film, the base of the palm portion along the length of the palm portion on either side or one side of the palm portion A synthetic resin shape-retaining tape is applied across the body film and a transparent small window is formed on one body film near the palm portion, and the palm portion is tilted to the small window side. The small window is closed, and the closed state of the small window is maintained by the synthetic resin shape holding tape.

  According to the present invention, when the palm portion is widened and opened to the left and right, the open state is maintained by the synthetic resin shape holding tape, so that the contents can be taken out smoothly. In addition to the above, in the case of a body film bag made of opaque light-shielding, the contents are seen through from the outside of the bag body through a transparent small window formed on one body film in the vicinity of the palm portion. The required amount of contents can be taken out. Furthermore, this small window has the convenience that the contents can be prevented from being discolored or deteriorated due to light such as ultraviolet rays or fluorescent lamps by closing the palm portion toward the small window.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In FIG. 1, reference numerals 1a and 1b denote two front and back body film, and gusset films 4 are interposed on both sides between the two front and back body films 1a and 1b to perform side seal 2 and the body film 1a. 1B is a synthetic resin bag body with a palm portion having a palm portion 3 extended from 1b as a content outlet, and is a horizontally placed three-dimensional type in which a chuck 4 is provided inside the palm portion 3; The body films 1a and 1b may be opaque opaque films or transparent films.

  Further, as shown in FIG. 3 (a), one side end 2 is side-sealed 2 on both sides between the front and back body film 1a, 1b without any gusset film, and the other is opened. It is a synthetic resin bag body with a palm portion that uses the palm portion 3 extended from the part films 1a and 1b as a content outlet, and is a horizontally placed flat type in which a chuck 4 is provided inside the palm portion 3 is there. The body films 1a and 1b may be either opaque opaque films or transparent films.

  The present invention relates to a synthetic resin bag body with a horizontally placed solid type or a horizontally placed flat type of the above-mentioned structure, with the palm portion 3 extending along the longitudinal direction of both sides or one side of the palm portion of the palm portion 3. A synthetic resin shape-retaining tape 5 is applied across the base and the body films 1a and 1b. The synthetic resin shape-retaining tape 5 is preferably a polyolefin such as polyethylene or polypropylene, for example, Forte (trade name, manufactured by Sekisui Chemical Co., Ltd., a polyethylene ultra-stretched sheet).

  Further, in the case of a bag body having a light shielding configuration by a horizontally placed solid type or a horizontally placed flat type opaque body film 1a, 1b having the above-described structure, A small window 6 made of a transparent film is formed on one side of the body film 1a, 1b in the vicinity of the portion 3.

  In addition, as an option of a commercial packaging design having a design property, the small window 6 can be formed in any other shape as shown in FIGS.

  Since the present invention has the structure as described above, the synthetic resin shape holding tape 5 is formed on the left and right sides of the palm portion 3 when the palm portion 3 is opened to the left and right in both the horizontal and flat types. Therefore, even if the contents are fragile, the bag can be smoothly taken out without being deformed. Moreover, since the opening state of the bag mouth can be maintained as it is during cooking by use of a microwave oven, it is possible to easily ensure an outlet for water vapor generated in the bag by heating.

  Since the synthetic resin shape-retaining tape 5 is a synthetic resin-based non-metallic material, particularly in the case of a food packaging bag, it can also correspond to a metal detector, which detects a metal mixed in the food packaging bag and detects a defective product. Can be detected, and the bag can be used for heat treatment by a microwave oven.

  Further, since the transparent small window 6 is formed in the body film 1a, 1b on one side in the vicinity of the palm portion 3, the user can easily see the contents stored in the bag body from the outside of the bag body. Since it is possible to take out the content while confirming the necessary amount, there is no need to take out the surplus amount and return it to the bag.

  As shown in FIG. 2, the small window 6 made of the transparent film can be shielded by closing the small window 6 with the palm portion 3 by closing the palm portion 3 to the small window 6 side. Prevents discoloration and quality deterioration due to light such as ultraviolet rays and fluorescent lights.

  Even when the palm portion 3 is tilted to the small window 6 side, the synthetic resin shape-retaining tape 5 is deformed following the tilt of the palm portion 3 so as to block the small window 6 and keep the small window 6 closed. Maintain state.

  Since the synthetic resin shape-retaining tape 5 of the present invention is flexible, the opening / closing operation of the palm portion 3, the tilting operation toward the small window 6, and the upright operation are easily performed without requiring a strong force. be able to.

  In the above-described embodiment, the bag body provided with the reopenable / closable chuck 4 in the joint portion 3 has been described. However, the present invention is also applied to a bag body without a chuck.
