Description

  The present invention relates to a bag with a zipper made of synthetic resin.

  As a bag body with a chuck made of synthetic resin, a bag body having a male and female nail type chuck on the inner surface near the opening is widely used. In such a bag with a chuck, in order to improve the ease of opening when the bag is opened, a non-slip surface having a large friction coefficient is provided on the outer surface corresponding to the chuck, It is practiced to form a plurality of parallel strips (see, for example, Patent Documents 1 and 2), and the strength of the bag body by forming a plurality of strips parallel to the chuck as a whole. It is also proposed to improve (see, for example, Patent Document 3). Further, a proposal has been made to make the chuck easy to close by adhering a highly rigid tape to the back surface of the chuck (see, for example, Patent Document 4).

  However, although the ease of opening is improved in the ones described in Patent Documents 1 and 2, the ease of closing is not considered, and the one described in Patent Document 3 is provided with an uneven strip on the inner surface of the bag. From the description that it may be, it is not considered at all about the ease of opening and closing. Moreover, although what was described in patent document 4 can eliminate the pain of the fingertip at the time of closing a chuck | zipper, since the surface which a fingertip contacts is a smooth surface, the material which forms a bag body, especially chuck | zipper Depending on the type of material on the back side of the chuck where the fingertip is slid and the state of the fingertip, the chuck may become difficult to close. In Patent Document 1, the slippery surface on which the nonslippery surface is not formed is picked up with a fingertip to eliminate the difficulty of closing by the nonslippery surface. For this reason, the chuck may be difficult to close as described above.

  For example, there is a difference in frictional resistance depending on the material on the back of the chuck, and various fingertip conditions such as wet fingers, sweated fingers, dry fingers, large fingers, small fingers, fingertip strength, glove wear, etc. Due to various factors, it is difficult to close the chuck when closing the chuck.

  Therefore, the present invention is capable of smoothly guiding the fingertip along the back surface of the chuck regardless of the difference in material and the state of the fingertip, so that the chuck can be closed easily and reliably. The purpose is to provide.

  In order to achieve the above object, the present invention provides a bag with a chuck made of synthetic resin having a male and female claw-type chuck on the inner surface in the vicinity of the opening. The present invention is characterized in that an uneven portion comprising a plurality of parallel ribs is provided.

  The uneven portion may be provided on an outer surface corresponding to the chuck and an outer surface near the opening, and the uneven portion formed on the outer surface corresponding to the chuck It is preferable that the length is 5 to 10 mm and that the chuck is formed vertically with the chuck at the center. Furthermore, you may provide the said uneven | corrugated shaped part in the whole outer surface. The rib strip has a height dimension of each rib strip of ½ or less of the width dimension, a width dimension of 1/5 to 1/10 of the pitch, and a width dimension and a height of each rib strip. It is preferable that the dimensions are 0.1 mm or less and the pitch is 1 mm or less. Furthermore, each said rib strip can also each form a cross-sectional shape in upward triangle shape.

  In the bag body with a chuck according to the present invention, an uneven shape portion composed of a plurality of rib strips parallel to the chuck is provided on the outer surface which is a back surface portion of the chuck. The fingertip does not come off the position of the chuck because it only needs to be slid along, and the chuck can be easily and reliably closed even by a powerless person such as a child or an elderly person. . Further, when opening the chuck, the fingertip hits in a direction substantially orthogonal to the ribs of the concavo-convex shape portion, and the fingertip is in a non-slip state, so that the chuck can be easily opened.

  Furthermore, the size of the concavo-convex shape portion in the vertical direction of the bag body is 5 to 10 mm, and the concavo-convex shape portion corresponding to the chuck can be satisfactorily captured by the fingertip by forming the concavo-convex shape portion vertically from the chuck. Even when the chuck is closed in a dark place, the position of the chuck can be recognized by the concavo-convex shape portion, so that the chuck can be reliably closed.

  In addition, by providing the uneven shape portion on the outer surface corresponding to the chuck and the outer surface in the vicinity of the opening, when the chuck is opened, the uneven shape portion provided in the vicinity of the opening is also non-slip, The chuck can be opened more easily.

  Furthermore, by providing the concavo-convex shape portion on the entire outer surface, the texture of the bag body can be made into a satin finish, and the design can be improved. Moreover, since the anti-slip | skid effect can be given to the whole outer surface, the usage form of a bag body can be expanded, for example, a use can be expanded also as equipment for cooking and preservation | save. Furthermore, when the bag bodies with chucks are stacked, the concavo-convex shape portions of the stacked upper and lower bag bodies do not collide with each other, and the transportability and storage stability can be improved. In addition, since the contact area is reduced by overlapping the concavo-convex portions with each other, even if static electricity is generated, the stacked bags with chucks can be reliably taken out one by one. Furthermore, there is no possibility of cargo collapse when transporting, storing, and displaying the products containing the contents in the bag with a chuck, and the labor and time required for each operation can be reduced.

  In particular, the height dimension of each rib strip is 1/2 or less of the width dimension, the width dimension is in the range of 1/5 to 1/10 of the pitch, and the width dimension of the rib strip is 0.1 mm or less, for example 0.08 mm, By making the height dimension 0.1 mm or less, for example 0.04 mm, and the pitch 1 mm or less, for example 0.6 mm, the feeling when touching the concavo-convex shape portion is good, and the design is also improved. Furthermore, by using such minute rib strips, it is possible to print on the surface, there is little adhesion of dirt between the rib strips, and cleaning is easy even when it is dirty.

  Further, by forming the cross-sectional shape of each rib strip in an upward triangle shape, the rib strip guides the movement of the fingertips upwards of the bag body, and feels resistance to the downward movement of the bag bodies. Therefore, the air inside the bag can be easily vented, and the contents at the bottom of the bag can be easily taken out.
