  First, a bag-like member opening device and a bag-like member opening method using the bag-like member opening device according to the first embodiment of the present invention will be described.

  First, the storage unit in which the bag-shaped member opening device is provided will be described. The definition of “storage part” is to store or hold the bag-shaped member in a properly wound state, and not only the configuration in which the bag-shaped member is completely stored, but also the bag-shaped member exposed to the outside. The structure of simply supporting in the state is also included. However, for convenience of explanation, the concept including all these configurations is referred to as a “storage unit”.

  As shown in FIGS. 1 to 3, the bag-shaped member opening device 10 according to the first embodiment is a mode in which the bag-shaped member opening device 10 is installed and used in a storage unit 12 such as a refrigerator, a stand, a box, or a winding device. The storage unit 12 stores or holds the bag-shaped member 14 in a state where the bag-shaped member 14 is appropriately wound.

  In FIG. 1, a configuration in which the bag-shaped member opening device 10 is installed below the roll of the support device that is the storage unit 12 is shown. FIG. 2 shows a configuration in which the bag-shaped member opening device 10 is installed above the roll of the support device that is the storage unit 12. FIG. 3 shows a configuration in which the bag-shaped member opening device 10 is attached to an opening of a box that is the storage unit 12. In addition, a roll means what was obtained by winding a bag-shaped member many times.

  As shown in FIG. 4, the bag-shaped member opening device 10 according to the first embodiment includes a storage portion 12 for storing or supporting a bag-shaped member 14 having an open end, or an installation portion 16 for installation in the vicinity thereof. And a contact portion 18 that causes the opening end 14A of the bag-shaped member 14 to be displaced 20 by pulling out the bag-shaped member 14 in a state where the one surface 14X of the bag-shaped member 14 is in contact. .

  The displacement 20 of the opening end 14A of the bag-shaped member 14 can be caused by, for example, the relative movement of the one surface 14X of the bag-shaped member 14 with respect to the other surface 14Y.

  The installation part 16 has the insertion opening part 22 in which a part of storage part 12 is inserted, for example. A part of the storage portion 12 is inserted or press-fitted into the insertion opening 22, and the bag-like member opening device 10 is installed in the storage portion 12.

  In addition, the installation part 16 may be installed in the storage part 12 or its vicinity by means other than a part of the storage part 12 being inserted into the insertion opening 22.

  Further, the dimensions and shape of the installation portion 16 are not particularly limited.

  The contact portion 18 is exposed toward the outside of the storage portion 12 in a state where the contact portion 18 is installed in or near the storage portion 12. In particular, the contact portion 18 is preferably located on the withdrawal path of the bag-like member 14. For this reason, when the bag-like member 14 stored or held in the storage part 12 is pulled out from the storage part 12, the contact part 18 contacts the one side surface 14 </ b> X of the bag-like member 14. Then, by pulling out the bag-like member 14 while maintaining the contact state, a frictional force is generated between the one side surface 14X of the storage portion 12 and the contact portion 18, which is in the direction opposite to the pull-out direction. Therefore, the surface 14X on one side and the surface 14Y on the other side of the bag-like member 14 move relative to each other. Thereby, the opening end 14A of the bag-like member 14 is opened.

  The contact portion 18 is one of rubber, silicon rubber, plastic rubber, urethane gel, rubber, elastomer, silicon gel, crystal gel, high-adhesion kagel, foamed silicon, foamed rubber, foamed resin and the like, and urethanes. Or a mixture of at least two or more, or a material similar to these. Thereby, the frictional force generated between the contact portion 18 and the bag-like member 14 is increased, and the opening end 14A is easily opened.

  The installation portion 16 and the contact portion 18 may be formed integrally, or may be configured by combining separate members by some coupling means such as adhesion and engagement.

  Here, the bag-like member 14 is assumed to be a plastic bag, for example. In a supermarket or the like, a plastic bag is installed in a wound state, and the opening end of the bag-like member 14 is overlapped as if it is closed. Therefore, the opening end 14A is easily opened by causing the opening end 14A of the bag-like member 14 to shift 20 by the bag-like member opening device 10 of the present invention. As a result, it is possible to save the user's trouble and to omit installation work such as a rag containing moisture.

  The positional relationship of the contact portion 18 with respect to the installation portion 16 is only an example in the present embodiment, and the contact portion 18 can be any of the upper side, the lower side, and the left and right sides of the installation portion 16, and is particularly limited. is not.

  The dimensions and shapes of the installation part 16 and the contact part 18 are not particularly limited.

  Here, the bag-like member 14 is closed in a state in which the opening end 14A is aligned, although the opening end 14A is formed, as is obvious if a plastic bag is taken as an example.

  When the bag-like member 14 is pulled out from the storage portion 12, the one-side surface 14 </ b> X of the bag-like member 14 eventually comes into contact with the contact portion 18. When the bag-like member 14 is pulled out as it is with the one-side surface 14X of the bag-like member 14 in contact with the contact portion 18, a frictional force is generated between the contact portion 18 and the one-side surface 14X of the bag-like member 14. Is generated, the one side surface 14X is pulled in a direction opposite to the drawing direction, and moves relative to the other side surface 14Y. Thereby, at the opening end 14A, the end portion of the one side surface 14X and the end portion of the other side surface 14Y were aligned, but due to the relative movement, the end portion of the one side surface 14X was moved to the other side. A displacement 20 is generated by moving relative to the end of the surface 14Y. As a result, the opening end 14A is opened and a gap can be formed.

  In particular, the bag-like member 14 is made of a vinyl material, and the contact portion 18 is made of rubber, silicon rubber, plastic rubber, urethane gel, rubber, elastomer, silicon gel, crystal gel, high adhesion kagel, foamed silicon, foamed rubber, The contact portion 18 and the bag-like member 14 are made of any one of foams such as foamed resins, urethanes, or a mixture of at least two, or a material similar to these.

Thereby, the bag-shaped member opening device 10 is not easily detached from the storage portion 12 or the vicinity thereof.

  Moreover, since the contact part 18 is comprised with the material of low hardness, it becomes easy to become familiar with the bag-shaped member 14. Thereby, the frictional force which generate | occur | produces between the contact part 18 and the bag-shaped member 14 becomes high, and generation | occurrence | production of the shift | offset | difference 20 can be accelerated | stimulated in 14 A of opening ends. As a result, the opening end 14A is easily opened.

  As a manufacturing method, for example, a single mold can be used to integrally form the two by thermocompression bonding while molding using a material having a high hardness and a material having a low hardness. In the case of rubber, for example, a rubber sheet is used.

  Further, for example, it is also possible to form them integrally by, for example, thermocompression bonding while molding each using a high hardness material and a low hardness material using different molds.

  Further, for example, various materials in a semi-fluid form may be poured into a mold and integrally molded.

  In addition, for example, while molding each using a material of a high hardness material and a material of a low hardness material using separate molds, both are assembled by bonding, engagement, etc. with an adhesive, a convex portion and a concave portion, etc. It may be.
