Description

  The present invention relates to a bag containing a granular material or a powdery material. Examples of the granular material or powdery material contained in the bag of the present invention include a non-slip agent or a gardening fertilizer that is sprayed on the road surface during the winter period.

  In snowy and cold areas, the road surface freezes in winter, so anti-slip agent is always provided on the side of the road so that pedestrians can freely spray anti-slip agent on pedestrian crossings. There are many examples. In such a case, it is common that a plurality of sachets containing an anti-slip agent are prepared in a box beside the road.

  However, when trying to spray the anti-slip agent, it was often the case that the anti-slip agent was put out too much. On the other hand, if the bag mouth is made small in order to avoid excessive application of the anti-slip agent, there is an inconvenience that it is difficult to pack the anti-slip agent. Therefore, there is a need for a bag that prevents over-slipping of the anti-slip agent while preventing it from becoming difficult to pack. In addition, since such a situation is applied also about granular materials or powdery substances (for example, fertilizer for gardening) other than a non-slip agent which does not have much storage capacity, this invention is such granular material or powdery form. It also applies to things.

  Therefore, an object of the present invention is to provide a bag for storing granular materials or powdered materials, which can prevent excessive packing while avoiding difficulty in packing.

  As for the bag which accommodates the granular material or the powdery material according to claim 1 of the present application, one end for putting the granular material or the powdery material and the other end for taking out the granular material or the powdery material are open. And is formed of one or two sheets, and a means for closing the one end is provided at a location adjacent to the one end, and the other end is It is partially closed so that an opening narrower than the entire width of the bag is formed, and an extension is provided at the other end of one side of the sheet, and the extension The narrow opening is closed by being folded and adhered to an adhesive portion provided on the other side of the sheet.

  The bag for storing granular material or powdery material according to claim 2 of the present application is characterized in that, in the bag of claim 1, the adhesive portion is formed of a double-sided tape or a pressure sensitive adhesive. It is.

  The bag containing the granular material or powdery material according to claim 3 of the present application is open at one end for putting the granular material or powdery material and at the other end for taking out the granular material or powdery material. And is formed of one or two sheets, and a means for closing the one end is provided at a location adjacent to the one end, and the other end is A plurality of first buttons are partially closed by penetrating both surfaces of the sheet at a predetermined interval, and an extension portion is provided at the other end of one surface of the sheet, The extension portion is folded back, and the second button attached to the extension portion is snapped onto the first button, whereby the opening at the other end is closed.
