Description

The present invention relates to an envelope-attached packaging bag.

A packaging bag composed of a packaging film generally has a vertical joint in which both ends in the width direction of the packaging film are overlapped and joined over the entire length in the length direction of the packaging film, and a predetermined length portion of the packaging film. It has a pair of horizontal joints in which both ends in the length direction are overlapped and joined, and a main body located between the pair of horizontal joints and accommodating a product.
As such a packaging bag, a gassho-pasted packaging bag in which the vertical joint portion protrudes from the main body portion and an envelope-pasted packaging bag in which the vertical joint portion constitutes a part of the main body portion are provided.
Conventionally, gassho-pasted packaging bags have been used for most of the packaging bags in which products on the market are enclosed.
In the gassho-pasted packaging bag, since the vertical joint is located at a different location from the main body, the vertical joint is designed so that it can be easily broken even at the vertical joint where two packaging films are stacked. Various structures have been proposed.
Then, in the gassho-pasted packaging bag, an auxiliary joint is provided at a portion of the main body adjacent to the widthwise end of one of the pair of horizontal joints, and an opening notch is provided in the auxiliary joint. The main body is cut from the opening notch so that the product can be easily taken out from the packaging bag (Patent Documents 1 and 2).

Japanese Unexamined Patent Publication No. 2004-256158 Japanese Unexamined Patent Publication No. 8-337251

On the other hand, in the gassho-pasted packaging bag, in the pair of horizontal joints, both ends of the vertical joints in the extending direction are tilted and joined to the horizontal joints, so that the vertical joints are joined at the horizontal joints. A total of four packaging film portions are overlapped and joined (heat-sealed), and two packaging film portions are overlapped and joined (heat-sealed) at other lateral joining portions.
Therefore, when forming the horizontal joint, there is a problem that uniform pressure cannot be applied in the extending direction of the horizontal joint, and the horizontal joint in a completely joined state cannot be easily formed. The current situation is that we have devised.
Further, in the gassho-pasted packaging bag, since the vertical joint portion is located on the main body portion and stands out, the portion of the main body portion where the vertical joint portion is not provided constitutes the front surface of the packaging bag, and the vertical joint portion is provided. The portion of the main body constitutes the back surface of the packaging bag, but since the back surface of the packaging bag is divided into two by the vertical joint extending over the entire length in the longitudinal direction of the main body, the back surface of the packaging bag is formed. In addition, there is a disadvantage in securing a large product advertising area that motivates the purchase of products.
Further, since the gassho-pasted packaging bag extends over the entire length of the main body in the longitudinal direction and has a vertical joint that stands out with respect to the main body, it is disadvantageous in increasing the commercial value of the product enclosed in the packaging bag. ..
Therefore, as in Patent Documents 1 and 2, an auxiliary joint is provided in the envelope-attached packaging bag at the position of the main body adjacent to one of the horizontal joints of the pair of horizontal joints, and the auxiliary joint is used for opening. It is conceivable to provide a notch and break the main body from the opening notch so that the product can be easily taken out from the packaging bag.

According to such an envelope-attached packaging bag, the two packaging film portions are overlapped and joined (heat-sealed) over the entire length in the longitudinal direction of the pair of horizontal joints, so that the horizontal joints extend in the extending direction. A uniform pressure can be applied, which is advantageous in easily and surely forming a lateral joint in a completely joined state.
Further, in the envelope-pasted packaging bag, the vertical joint portion extends continuously with the main body portion and the vertical joint portion forms a part of the main body portion, so that the vertical joint portion is conspicuously located on the main body portion like the gassho-pasted packaging bag. There are no vertical joints, and the main body where the vertical joints are located can also be used as the front of the packaging bag, thus ensuring a single large product advertising area on both the front and back of the packaging bag. It will be advantageous.
Further, since the envelope-pasted packaging bag does not have a conspicuous vertical joint portion unlike the gassho-pasted packaging bag, it is advantageous in increasing the commercial value of the product enclosed in the packaging bag.
However, in the envelope-attached packaging bag, the vertical joint portion constitutes the main body portion, and two packaging films are stacked at the vertical joint portion, so that one of the horizontal joint portions is the horizontal joint portion. Even if an auxiliary joint portion having an opening notch is provided at a portion of the main body adjacent to the main body and the main body is torn from the opening notch, the vertical joint is not easily broken and the packaging bag is difficult to open.
In this case, in the envelope-pasted packaging bag, the vertical joint portion constitutes the main body, so if the structure of the vertical joint portion of the gassho-pasted packaging bag is applied to the vertical joint portion of the envelope-pasted packaging bag, the vertical joint portion may be applied. The main body is easily torn at this point, which causes a problem in the durability of the envelope-attached packaging bag.
Under these circumstances, an envelope-attached packaging bag in which an opening notch is provided in the main body so that the product can be easily taken out from the packaging bag has not been provided on the market.
The present invention has been devised in view of the above circumstances, and the present invention allows the product to be easily taken out from the packaging bag by breaking the main body from the opening notch provided in the main body. Durability is ensured, a perfectly joined horizontal joint is easily and reliably formed, a large product advertising area is secured on both the front and back of the packaging bag, and the commercial value of the product enclosed in the packaging bag is enhanced. It is an object of the present invention to provide an envelope-attached packaging bag which is advantageous for enhancing.

In order to achieve the above-mentioned object, the present invention comprises a vertical joint portion in which the end portions of the widthwise film at both ends in the width W1 direction of the packaging film having the width W1 and the length L1 are overlapped and joined in the length L1 direction. At the location of the packaging film located between the pair of lateral joints formed by overlapping and joining the end portions of the film in the length direction at both ends of the predetermined length portion along the length L1 direction and the pair of horizontal joints. It includes a main body portion formed in a hollow shape by a certain main body portion film and accommodating a product, and the vertical joint portion extends continuously with the main body portion film to form a part of the main body portion film. , An envelope-pasted packaging bag having a width W2 and a length L2 corresponding to the width W1 and the length L1 of the packaging film, and the main body portion adjacent to one of the horizontal joint portions of the pair of lateral joint portions. An auxiliary joint portion for joining the films of the main body portion facing each other is provided at an end portion in the width W2 direction, an opening notch is provided in the auxiliary joint portion, and extends in the width W2 direction through the opening notch. At the portion of the vertical joint including the virtual line, the portion of the overlapped width direction film end portion located inside the main body portion located on the opening notch side at the inside width direction film end portion. It is characterized in that a breaking region is provided so that the vertical joint portion can be easily broken.

According to the present invention, when the main body portion is broken from the opening notch and the torn packaging film reaches the vertical joint portion, the main body portion is easily torn at the vertical joint portion through the broken region and opened. The envelope-attached packaging bag can be easily opened from the notch.
Further, since the fracture region is covered by the outer width direction film end portion located outside the main body portion of the overlapped width direction film end portions at the vertical joint portion, the fracture region may be provided in the main body portion. Regardless, it is advantageous in ensuring the durability of the envelope-attached packaging bag.
Therefore, according to the present invention, the main body can be easily taken out from the packaging bag by breaking the main body from the opening notch provided in the main body, and a horizontal joint in a completely joined state can be easily and surely formed. It is possible to secure a large product advertising area on both the front and back sides of the packaging bag, and to provide an envelope-attached packaging bag that is advantageous in increasing the commercial value of the product enclosed in the packaging bag.
