Description

  The present invention relates to an accommodation bag that can accommodate articles of various properties (forms) such as powder, gel, and sticky articles, foods, and pharmaceuticals.

  For example, powdered milk bags that contain powdered milk and are portable are known as bags that contain powdered articles (Patent Documents 1 to 3).

Registered Utility Model Publication No. 3056992 Japanese Patent Laid-Open No. 10-310150 Japanese Patent Laid-Open No. 10-211985

  Since the bottom part of the bag for powdered milk described in Patent Document 1 has a square shape, when the powdered milk is taken out from the opening, the powdered milk is clogged at the corners of the bottom part, and it may take time to take all the powdered milk.

  The powdered milk bags described in Patent Documents 2 and 3 have a funnel shape at the bottom, a part of the funnel-shaped bottom part can be cut out, and the powdered milk can be taken out from the bottom side. No, but it takes time to discharge the milk powder because the outlet is narrow. In addition, there is a trouble that powdered milk is spilled when the bottom part is cut off, and that the cut piece must be disposed of.

  An object of the present invention is to provide a storage bag in which the contents in the bag can be taken out smoothly and quickly, and further, an article can be taken out without remaining in the corner of the bag.

  The storage bag of the present invention is a storage bag in which an article can be taken in and out, and includes an opening, a bottom, and a storage, the storage is a substantially inverted triangle from the opening to the bottom, and the bottom is a substantially triangular that is pointed downward. Is. The substantially upper half of the accommodating part may have substantially the same width as the opening, the substantially lower half to the bottom part of the accommodating part may be a substantially inverted triangle, and the bottom part may have a substantially triangular shape with a sharp downward point. The side surface of the housing portion is a substantially inverted triangle from the opening to the bottom, and the bottom is arcuate. A gripping part can also be provided on the outer side of both or one of the bottom part and the accommodating part. The accommodating portion may be a substantially inverted triangle from the opening to the bottom, the bottom may be a substantially triangular that is sharp downward, and may be provided with a substantially triangular gripping portion upward from the outside of the opening to below the bottom. . The horizontal width of the substantially upper half of the accommodating portion is substantially uniform, the substantially lower half of the accommodating portion is a substantially inverted triangle, and a gripping portion may be provided outside the substantially lower half of the accommodating portion.

  Since the bottom of the storage bag of the present invention is tapered downward, the contents in the storage bag are smoothly and rapidly discharged when the storage bag is turned upside down. Moreover, the contents do not remain in the corners of the storage bag.

(A)-(g) is explanatory drawing which shows the various examples of the accommodation bag of this invention.

(Embodiment)
Embodiment of the storage bag 1 of this invention is described with reference to drawings. The storage bag 1 of the present invention stores articles of various properties (forms) such as various powders such as powdered medicine, sugar, salt, milk, gel-like materials such as yogurt, and viscous foods such as natto and chopped kelp. It is a packaging bag (containment bag). The material can be made of various materials such as resin film (including sheet) and paper.

  As an example, the storage bag 1 shown in FIGS. 1A and 1B includes an opening 2, a bottom 3, and a storage 4, and the side surface 5 of the storage 4 is an inverted triangle from the opening 2 to the bottom 3. The bottom 3 has a sharp triangle pointing downward. The side surface 5 and the bottom portion 3 are sealed. The angle of the bottom 3 can be arbitrarily designed, but in the illustrated example, it is about 30 degrees.

  The storage bag 1 shown in FIG. 1 (c) has an approximately upper half of the storage portion 4 having the same width as that of the opening 2, an inverted triangle from the substantially lower half of the storage portion 4 to the bottom 3, and the bottom 3 facing downward. It has a sharp triangular shape. Also in this case, the side surface 5 and the bottom 3 are sealed.

  A storage bag 1 shown in FIG. 1 (d) has a storage portion 4 that is an inverted triangle from the opening 2 to the bottom 3, the bottom 3 is arcuate, and a grip 6 is provided below the bottom 3. The side surface 5 and the bottom 3 are sealed. The gripping portion 6 only needs to be wide enough to be gripped by a hand or a gripping tool, and the shape, width, etc. can be arbitrarily designed.

  In the storage bag 1 shown in FIG. 1 (e), the storage portion 4 is formed in an inverted triangle from the opening 2 to the bottom 3, the bottom 3 is formed in a sharp triangle downward, and from the outside of the opening 2 to the bottom of the bottom 3. An upward triangular gripping portion 6 is provided. Also in this case, the side surface 5 and the bottom 3 are sealed.

  The storage bag 1 shown in FIG. 1 (f) is provided with a gripping portion 6 on the outer side of the substantially lower half, with the lateral width of the substantially upper half of the housing portion 4 made uniform and the substantially lower half of the housing portion 4 made an inverted triangle. It is a thing. Again, the side 5 and the bottom 3 are sealed.

  The storage bag 1 of the present invention can be made of, for example, a plastic material such as polyethylene, polypropylene, polyester, nylon, or paper, but can also be made of other materials.

  As shown in FIG. 1 (g), the storage bag 1 of the present invention can also be provided with a sealing means 7 that can be opened and closed, such as a zipper or a planar tape, at the opening 2.

  The storage bag 1 illustrated as an example has a flat shape in which two resin films are stacked, but the storage bag 1 of the present invention may be three-dimensional. In this case, the opening 2 to the bottom 3 can be made into a pyramid shape or a cone shape so that it can be folded flat.

(Example of use)
The usage example of the storage bag 1 of this invention is demonstrated. Here, the case where powder is stored in the storage bag 1 and the powder is opened (taken out) will be described as an example.
(1) Opening the opening 2 of the storage bag 1 and putting (accommodating) powder into the storage 4 from the opening 2.
(2) After the housing, the opening 2 is sealed. In this case, when the container 1 is provided with the sealing means 7, the sealing means 7 is used for sealing, and when the sealing means 7 is not provided, the opening 2 is sealed with a string, tape, rubber band or the like. Close with stoppers.
(3) When taking out (opening) the powder (contents) from the containing bag 1, the opening 2 is opened by opening the sealing means 7 or removing another sealing tool.
(4) In the opened state of (3), the opening 2 is turned down, the bottom 3 is turned up (the storage bag 1 is turned upside down), and the contents are dropped from the opening 2 by its own weight. In this case, the gripping part 6 can be pinched by hand.

  In the above description, a triangle, an inverted triangle, and a uniform lateral width are described, but they all include a substantially triangular shape, a substantially inverted triangle, and a substantially uniform lateral width.

  The above description describes the case where the storage bag 1 is small and the contents can be taken in and out by hand, but the storage bag 1 of the present invention may be used for large business use or industrial use, In that case, the storage bag 1 is hung with a machine, for example, a crane, the opening 3 is opened and an article is packed in the storage 4, or the holding part 6 is held with a crane and hung upside down. It is also possible to open the part 2 and open an article in the housing part 4. In the case of business use or industrial use, the material of the storage bag 1 can also be made of a strong material such as cloth or leather.
