Description

  The present invention relates to a synthetic resin obturator for bags and openings used when closing the openings of a wide variety of bags such as those made of resin.

  In order to prevent the contents from accidentally coming out of a resin bag that does not have a means for closing the opening, such as a plastic bag, the opening is closed with a rubber band, an adhesive tape, a clip, or the like.

  Closing the opening of plastic bags such as plastic bags with rubber bands is inexpensive and easy, but is not suitable for closing heavy bags with heavy weight, and is generally limited to thin materials such as plastic bags. In addition, it often takes time to open and close the bag, and the bag is often damaged during the operation.

  The present invention is easy to use, can easily close the mouth of bags, and can be used to close the opening of a wide variety of bags, such as those using thin materials or thick materials. It was created for the purpose of providing an obturator.

  A flat base piece, and a string provided continuously with the base piece and provided with a spherical protrusion on the tip side, a slit having a diameter through which a portion without the spherical protrusion of the string body can be inserted; An insertion hole communicating with the slit and having a diameter smaller than the diameter of the spherical protrusion is provided along the thickness direction of the base piece.

  According to the present invention, the spherical protrusion is formed by winding the string body around the bag opening side and moving the string body portion along the longitudinal direction of the string body in the slit provided in the base piece to engage the insertion hole. Locked to the base piece, the bag opening can be reliably kept closed, and the bag can be easily opened by removing the spherical protrusion from the edge of the insertion hole. It is possible to provide a synthetic resin obturator having a bag opening that is easy to use.

  The drawings show one embodiment of the synthetic resin obturator for the bag opening according to the present invention, FIG. 1 is a perspective view, and FIG. 2 is a partially cutaway enlarged perspective view showing a use state.

  In the figure, A is a synthetic resin obturator for bags and the like according to the present invention, 1 is a base piece of the obturator A, and the base piece 1 is a flat body that can be grasped with a fingertip, The obturator A is constituted by the string body 2 continuously provided at one end on the peripheral side.

  The base piece 1 made of a flat body is provided with a triangular notch 3 whose both edges are gradually approaching in the depth direction on the circumferential side thereof, and at the back end of the notch 3, A slit 4 having a smaller diameter than the diameter of the non-existing portion 2a is provided, and the notch 3 and the insertion hole 5 formed in the central portion of the base piece 1 are communicated with each other through the slit 4 so that the spherical protrusion 6 of the string body 2 The part 2a that does not exist can freely move between the notch 3 and the insertion hole 5. The notch 3 serves as a guide when the string body 2 is engaged and inserted into the slit 4, and the presence of the notch 3 enables smooth engagement and insertion.

  The string body 2 has a diameter that can be moved to the position of the insertion hole 5 through the slit 4, and has a plurality of spherical protrusions 6 at the distal end side with a width wider than the thickness of the base piece 1. The spherical protrusions 6 are arranged in a line and formed in a spherical shape having a diameter larger than the diameter of the insertion hole 5 in the form of being arranged on the axis of the string body 2 and provided in the middle portion of the slit 4. The insertion hole 5 is partially engaged and locked thereto.

  Then, a string body is wound around the opening b ′ having a reduced diameter of the bag body b so as to close the opening, and an appropriate spherical protrusion 6 provided on the string body 2 is inserted into the slit 4 so that a part of the string body is in the longitudinal direction. The both ends of the obturator A (the base piece 1 and the distal end side of the string body 2) are connected to each other by being partially engaged with the insertion hole 5 and locked together. It maintains the closed state of the opening of the body and functions as an obturator.

  The plurality of the spherical protrusions 6 arranged in the string body 2 can be used to close the opening of the bags corresponding to the winding diameter of the string body 2 of the opening b ′ whose diameter is reduced in the bag body b. In this case, if it is used for bags having a substantially constant winding diameter, there is no inconvenience even if this spherical protrusion 6 is single, and the unnecessary spherical protrusion 6 portion cuts the string 2. May be removed.

Perspective view. FIG. 3 is a partially broken enlarged perspective view showing a use state.
