Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a bag body made of synthetic resin that is provided with a gripping hole for a hand and an articulating tool for opening and closing.

<Prior art> Synthetic resin carrying bags equipped with an opening/closing device near the opening and a gripping hole for the hand above the device are disclosed in, for example, Utility Model Publication No. 11451/1973 and Utility Model Publication No. 46/1983. -24135.

<Problems to be solved by the invention> In the conventional carrier bags mentioned above, the thickness of the film near the gripping holes is made thicker in order to prevent the handles (gripping holes) from tearing and breaking when heavy items are placed inside the bag. Alternatively, a plurality of gripping holes are formed by forming a bridge portion with a film. In this case, tearing of the handle is prevented, but when a bag containing a heavy item is lifted by inserting the hand into the gripping hole, the load is concentrated on the gripping hole because the film is extremely flexible. The opening is deformed. As a result, the articulator was also twisted and deformed, causing the male and female claws that had been closed in occlusion to come loose and open.

Further, the entire bag including the opening of the gripping hole is formed of a single layer of polyethylene film.
Although this polyethylene film has a high tensile strength, it does not have a soft feel, so when you insert a hand into the gripping hole to hold a bag containing a heavy item, the film will dig into your hand and cause pain, causing pain in your left and right hands. It was often necessary to change hands.

Furthermore, polyethylene film does not have cushioning or thermal insulation properties. Therefore, when the bag is filled with broken objects such as glass bottles, it may be damaged if it hits a concrete wall, etc., and the bag may deteriorate over a long period of time when it contains living things, such as during the summer.

<Means for Solving the Problems> The present invention provides a bag with a gripping hole that solves the above-mentioned conventional problems, and its characteristic configuration is that an articulating tool for opening and closing is provided near the opening. A synthetic resin bag is provided with a gripping hole for a hand above the articulating tool, and the inner layer of the bag is formed of a polyethylene film provided with the articulating tool, and the outer layer of the bag is thicker than the inner layer film. It has a two-layer structure, an inner and outer layer made of foamed plastic film. It consists of:

<Function> The present invention has a multi-layer structure consisting of an inner layer of polyethylene film and an outer layer of foamed plastic film, which prevents deformation of the opening near the gripping hole due to weight, and provides a soft feeling when gripping the gripping hole due to the foamed plastic film. The bag body provides cushioning and heat insulation properties, and eliminates biting into the hands.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. In FIG. 1, 1 is a bag body, 2 is an opening/closing articulating tool provided near the opening 7, and 3 is a gripping hole, which is provided above the articulating tool 2.

The present invention provides a second method for carrying bags such as those mentioned above.
As shown in the figure, the inner layer of the bag body 1 is formed of a polyethylene film 5, and the outer layer is formed of a foamed plastic film 4 made of polyurethane or the like to form an integral part of the inner and outer layers.
Layer formation. The outer layer of foamed plastic film 4 is made thicker than the inner layer of polyethylene film 5, and the articulating tool 2 is formed on the inner layer of polyethylene film 5. Also,
Thick wall of the foamed plastic film 4 of the outer layer near the opening B of the bag body 1 including the articulating tool 2 and the gripping hole 3
T ₂ is a thicker layer 6 than the thicker wall T ₁ of other parts.

Since the present invention has the above-mentioned structure, the polyethylene film 5 as the inner layer on which the articulating tool 2 is formed has the strength of the foamed plastic film 4 as the outer layer, which is harder and more elastic than the polyethylene film. Since the bag 1 is reinforced by the foamed plastic film 4, even if the bag 1 contains a heavy object and is lifted by inserting a hand into the gripping hole 3, the load will be distributed to the outer foamed plastic film 4, and the gripping hole 3 will be reinforced. The torsional deformation of the opening 7 is significantly reduced because the deformation is not concentrated in one area. This eliminates the spread of torsional deformation to the articulating tool 2, and prevents the closed articulating tool from releasing naturally. Further, as mentioned above, the load is not concentrated on the gripping hole 3, and the thickness of the foamed plastic film 4 as the outer layer prevents the hand from biting into the hand, which solves grip pain and provides a soft feel. Furthermore, due to the cushioning properties of the foamed plastic film 4 in the outer layer, even if the bag 1 containing broken objects hits a concrete wall, the contents will not be damaged due to its cushioning effect, and its insulation properties will prevent living things or frozen objects from being stored in the summer. Even if it is placed in the bag body 1, it can be stored for a long time without deterioration or thawing.

<Effects of the Invention> As described above, according to the present invention, since the inner layer is a polyethylene film and the outer layer is an integral composite layer of a foamed plastic film, it is a carrying bag with a gripping hole. The outer layer of the foamed plastic film, which is easy to tear, is protected by the inner layer of polyethylene film. Since the outer layer of the foamed plastic film is thicker than the outer layer of the foamed plastic film, it can prevent deformation of the articulating tool and tearing of the gripping hole, and eliminates the problems of the conventional single-layer polyethylene gripping hole and carrying bag with the articulating tool. It has the effect of eliminating all problems and improving the effectiveness of use.
