  • the present invention relates generally to a stretchable bag, more particularly to a stretchable bag adapted for receiving articles and having an opening that allows opening or closure thereof.
  • a primary object of the present invention is to provide a stretchable bag that is compact In appearance but can be stretched to hold a number of articles, and that has an opening that can be stretched to allow placement of articles and that can contract thereafter to prevent the articles from falling out.
  • a stretchable bag includes an enclosed bag body made of a bag fabric.
  • the bag body has an opening at one place thereof.
  • the bag fabric includes an elastic layer and a surface layer adhered thereto.
  • the elastic layer is preferably formed from foamed polybutylene gum or styrene or butadiene gum.
  • the surface layer being preferably formed a fabric of nylon yarns or polyester yarns.
  • the bag body has an elasticity that enables the opening to be stretched open to facilitate placement of articles into the bag body and to contract thereafter to ensure that the contents of the bag body do not fall out.
  • At least one side of the bag fabric is provided with an ornamental layer to enhance visual effects.
  • a stretchable bag includes an enclosed bag body 1 formed by a bag fabric sewn to define an enclosed interior space for receiving articles, the bag body 1 having an opening 2 formed in a suitable position.
  • the bag fabric 1 includes an elastic layer 11, a surface layer 12 adhered to an upper side of the elastic layer 11, and a bottom lining 13 attached to a lower side of the elastic layer 11.
  • the elastic layer 11 is formed from a foam material having stretching elasticity. Experiments show that foamed polybutylene gum or foamed styrene or butadiene gum is preferred.
  • the surface layer 12 and the bottom lining 13 are fibrous fabrics that match the elastic layer 11 to achieve elastic effects. Hence, they are preferably formed from nylon cloth or polyester cloth woven from nylon yarns or polyester yarns.
  • the surface layer 12 and the bottom lining 13 are adhered to the elastic layer 11 in a conventional way.
  • an adhesive or glue may be applied and roller pressing may be utilized to achieve firm attachment
  • the opening 2 on one side of the bag body 1 may be a slit that is linear or that has the shape of a cross, star, circle, etc.
  • the opening 2 is cross-shaped.
  • the opening 2 may also be partially hollowed out.
  • one side of the bag of the present invention may be provided with an ornamental layer 14.
  • the ornamental layer 14 may be formed by adhering stickers or using transfer printing, printing, or other conventional methods.
  • the shape of the bag can further be dictated by the shape of the decoration on the ornamental layer 14.
  • the bag is in the shape of a hippopotamus. Certainly, the bag can have any desired ornamental shape.
  • the present invention is adapted for use on wallets.
  • the bag is additionally provided with a closure layer 4 at the end opposite to the opening 2.
  • One end of the closure 4 is provided with a closing device 3.
  • the bag of the present invention confines two receiving spaces for receiving articles.
  • the ornamental layer 14 it can be provided on an outer surface of the closure layer 4.
  • the closing device 3 may be a conventional zipper or hook-and-loop tapes or other equivalent means.
  • the present invention may have various changes.
  • the opening 2 and the ornamental layer 14 can be formed on the same surface or opposite surfaces of the bag.
  • the opening 2 is disposed at a specific portion of the ornament an the ornamental layer 14, for instance, at the mouth portion of an animal ornament, to achieve a funny visual effect.
  • the design of the ornament can be kept intact.
  • Fig. 5 shows the third preferred embodiment of the present invention.
  • This embodiment is adapted for use in a stationery bag, such as a pencil bag.
  • the closure device 3 is provided on the opening 2. Therefore, in use, the closure device 3 allows or doses access to the interior of the bag for placement or removal of articles.
  • the bag of the present invention has a tensile strength at least over 8kg/cm, and a stretchability as high as over 500%. Therefore, the fabric bag 1 can have a larger receiving capacity in use.
  • the opening 2 can be very small in size.
  • the opening 2 can be stretched to allow easy access to the interior of the fabric bag 1. After placement of articles, the opening 2 will resume its original size to prevent the contents of the bag from falling out.
  • the bag of the present invention is resistant to water, light in weight, resistant to stretching, and durable.
  • the present invention is inexpensive to manufacture.
