Abstract
The outer surface of an article is covered with a wrapping film, and the both edges of the film are lap-welded with each other to constitute a body seal section. A first slit is formed along the body seal section, substantially parallel thereto, and is spaced a small distance apart therefrom. A second slit is formed in the body seal section substantially at right angles or an inclined angle to the edge of the body seal section. When the end of the first slit is peeled off, the film splits along the body seal section and also towards the second slit. The second slit helps the split to stretch further in the transverse direction of the article. As a result of this, the wrapping film splits in both the longitudinal and lateral directions thereof.
Claims17
An article is covered with a wrapping film, and a body seal section is made by making both ends of the wrapping film overlap with each other and bonding them together, the improvement comprising:
- a first slit formed, substantially parallel to both the edge of a lower section of film and the body seal section, on the edge of an upper section of the film which is in the body seal section;
- and
- a second slit formed on the periphery of the lower section of the film at a right angle to the first slit in such a manner as to traverse the body seal section.
A wrapped article in which the outer surface is covered with a wrapping film and a body seal section is formed by making both ends of the wrapping film overlap with each other and bonding them together while the longitudinal periphery of the body seal section closer to the edge of a lower film is kept unbonded, the improvement comprising:
- a first slit formed substantially parallel to the edge of the lower film portion in the unbonded periphery of the body seal section;
- and
- at least one second slit formed on the periphery of the lower film portion in the bonded portion of the body seal section at an angle to the first slit in such a manner as to traverse the body seal section.
A wrapped article in which the outer surface is covered with a wrapping film and a body seal section is made by making both ends of the wrapping film overlap with each other and bonding them together, the improvement comprising:
- an unbonded part, where an upper film and a lower film are not bonded together, formed in the body seal section in such a manner that the unbonded part covers at least a part of the edge of the upper film and does not transversely extend to the edge of the lower film;
- a first slit formed in the unbonded-part at an angle to the edge of the unbonded part in such a manner as to transverse the unbonded part;
- and
- a second slit formed in the lower film in the body seal section, and having
- a second slit starting portion extending to the inside of the body seal from an initial point on the edge of the lower film and
- an extended portion that continually extends from the second slit starting portion in a direction moving away from the first slit, in which the second slit is formed in such a way that the second slit starting portion and the extended portion extend away from each other in relation to the first slit.
An article is covered with a wrapping film, and a body seal section is made by making both ends of the wrapping film overlap with each other and bonding them together, the improvement comprising:
- a first slit formed, substantially parallel to the edge of a lower section of film, on the edge of an upper section of the film which is in the body seal section;
- and
- a second slit formed on the periphery of the lower section of the film at an inclined angle to the first slit in such a manner as to traverse the body seal section.
An article is covered with a wrapping film, and a body seal section is made by making both ends of the wrapping film overlap with each other and bonding them together, the improvement comprising:
- a first slit formed, substantially parallel to the edge of a lower section of film, on the edge of an upper section of the film which is in the body seal section;
- and
- a second slit formed on the periphery of the lower section of the film at a right angle to the first slit in such a manner as to traverse the body seal section;
- wherein the second slit is formed in the vicinity of the first slit.
An article is covered with a wrapping film, and a body seal section is made by making both ends of the wrapping film overlap with each other and bonding them together, the improvement comprising:
- a first slit formed, substantially parallel to the edge of a lower section of film and the body seal section, at a position spaced away from the edge of the upper section of the film;
- and
- a second slit formed on the periphery of the lower section of the film at a right angle to the first slit in such a manner as to traverse the body seal section.
