Description

The present invention relates to a method of taking out a bag, and more particularly to a method of taking out a bag connected in a roof tile shape from its container.

When packaging products, the efficiency and speed of the overall packaging process is often determined by the ease with which the operator obtains the bags to use in the packaging process. Since it is important for the operator to take out the bag during the packaging process, various techniques have been devised to facilitate and accelerate the packaging process. It is highly desirable to facilitate handling of the bag when the operator is or is about to fill the product into the unpacked bag by the bag unpacking step. An object of the present invention is to provide a container for taking out a chain-shaped bag connected in a roof tile shape of the bag.

Many attempts have been made to design such a dispensing container. An example of this is British patent specification No. 1 entitled "Plastic bag or container for taking out similar articles" by Deards et al. On January 13, 1977.
It is described in No. 1,461,410. This patent describes a container for removing a stack of flat, flexible products of plastics film, the container having a pair of opposing generally parallel walls, one of which is Is provided with an opening forming at least a part of a take-out hole, the other being the bottom of a container for supporting the stack, the bottom having an elongated ridge protruding inwardly. And the ridge is disposed substantially along its longitudinal axis and faces the opening along at least a portion of the length of the ridge. Another example of a dispensing container is described in U.S. Pat. No. 4,064,880, Dec. 27, 1977, entitled "Men's Tubular Sanitary Napkin" by Logan. This patent relates to a disposable napkin for diapers or toilets made of absorbent material, the napkin being made from a set of napkins joined together,
The set of napkins is placed in a dispenser that has a separating device that brings it to a position for removing one napkin and then the next.

As generally relevant to the present invention, Hannon
on) entitled "Bag Package" in U.S. Pat. No. 3,161,347, dated Dec. 15, 1964, which relates to a bag that is open at one end and that extends in the longitudinal direction of the package. A number of bags consisting of a support member, such as a carrier tape, open at one end, are arranged in a stacked arrangement along the member, a portion of each bag contacting the member, each bag at the same end of the package. Each of the preceding bags overlaps in a given direction along the support to close the opening of the next bag, and the adhesive member is adjacent to the opening. A member is provided between one side of each bag and which temporarily holds the bag with respect to the member.

Also titled Wing "Bag Package"
U.S. Pat. No. 3,587,844 dated June 28, 1971 is also of general relevance to the present invention. The patent relates to a package of pilings that are concatenated like a roof tile, wherein each pouch behind the bottom pouch is offset forward from the next lower pouch and over the opening of the pouch below. ing. The upper side of the lower bag is sequentially attached to the bottom of the upper bag by an adhesive. When one bag is taken out and the chain is positioned so that the bag to be taken out first is placed on a flat surface, the bag to be taken out first is expanded to form a relatively square shaped opening.

According to the invention, it consists of (a) a chain of piling-like bags which are successively stacked and glued together, and (b) a container for the chain of bags, each of which precedes the chain. With an open end facing towards the end, the container has an upper part and a lower part adapted to be fitted together, and the upper part is slidable along the outside of the lower part, the upper part being generally Having a first pair of generally parallel and opposite sidewalls and a second pair of generally parallel and opposite sidewalls, the upper portion also having a fold line provided at the top of the upper portion. Also has a hole, the upper part also being adapted to be cut through the hole,
The hole has at least a portion disposed in one of the first pair of sidewalls, and the fold line includes a portion of the hole relative to the one sidewall that includes the portion of the hole. The fold line is generally parallel to the one side wall and closer to the opposite side wall, and the fold line is formed by cutting a portion of the top along with the hole along the hole. For removing the bag characterized in that the flap can be folded over the fold line so that an opening is provided at the top for extracting the leading end of the chain. A package of bags connected in the shape of a roof tile is provided.

Further, according to the present invention, (a) a chain of roof tile-shaped bags is formed by using bags that are bonded in a state of being sequentially stacked but are connected so as to be removable, and at this time, each bag has the chain. Have an open end facing the leading end of
The chain of bags is placed in a container, the container having an upper portion and a lower portion adapted to fit together, and the upper portion being slidable along the outside of the lower portion, the upper portion generally being Having a first pair of generally parallel and opposite side walls and a second pair of generally parallel and opposite side walls, the upper portion also having a fold line provided at its top,
(C) providing a hole in the top such that the top can be cut through the hole such that the hole is at least partially located within one of the first pairs; A line is closer to the one side wall that includes a portion of the hole than to another side wall that is generally parallel to and opposite the one side wall that includes a portion of the hole, and the fold line is the hole. And defining a flap made by cutting a portion of the top along the hole, the flap being foldable above the fold line, thereby leading the chain at the leading end. There is provided a method of manufacturing a roof tile bag package for removing the bag, which comprises the step of providing an opening for removing the bag.

The packages and methods of the present invention eliminate the need for fumbling the leading portion and removing the container lid. If the lid is removed, for example, if the main use of the bag is meat packaging and meat debris easily falls into the lidded container on a production line, the bag contained in the container will be contaminated. There is a possibility. Therefore, it is an object of the present invention to provide a package and a manufacturing method thereof that not only facilitates the taking out of a bag on a production line but can substantially prevent contamination of meat by scraps.

 The present invention will now be described in detail with reference to the accompanying drawings.

The bags in the chain are substantially identical and are preferably made from tubular film in the conventional manner, each bag having two sides, a bottom and an open end forming the mouth of the bag. Depending on the method of cutting and sealing the tubular portion, the bag can be of the normal side-sealed type or the normal end-sealed type. The uppermost pouch, like all pouches in the chain, has its mouth facing the leading end of the chain, and the weight of the overlapping pouches holds the pouches of the lower pouch closed to prevent debris. Is prevented from entering the bag.

The term "chain of bags connected in the shape of roof tiles at the time of bonding" means that the bags are arranged side by side like tiles are tiled or roof is covered, and adjacent bags are adhesive areas or They are detachable from each other at points and are adhesively connected. This method of connecting in the shape of a roof tile is described in the Wing patent. The term also refers to a series of shingled bags releasably adhesively connected to a longitudinal member, such as a carrier tape extending in the longitudinal direction of the chain, as described in the Hannon patent example. Means In the former method of connecting in a tile shape with an adhesive, the force exerted on the preceding bag in the chain is transmitted to the bag below the chain,
On the other hand, in the latter method in which the adhesive tape is connected in a roof tile shape, such a force is transmitted along the carrier tape and is not transmitted from bag to bag.

The roof tile-like chain of the bag is preferably a tape type. The reason for this is that if the middle bag of the tape-like chain accidentally comes off, the remaining bags are still connected to the tape, which causes one bag in the shingled chain to accidentally come off. However, even if the adjacent bags are connected to each other at the bonding point, the problem of breaking the chain can be prevented.

The chain of bags, glued together like a roof tile, is folded into the container and the leading end of the chain is directed toward the flap at the top of the container, which flap, when opened, is The bag is shaped so that the bag is withdrawn and the remaining bags follow, thus removing the bag from the container. The container is preferably a disposable container, such as cardboard, the width of which is somewhat wider than the width of the chain of bags and is deep enough to hold the desired supply of bags.
The bag chain is usually folded in a corrugated manner, filling the box to the desired depth, with the leading end of the bag chain oriented such that it is fed through an opening in the top of the container, The leading end of the chain is defined as the end of the chain with the top bag in the chain of shingled bags. In the accompanying drawings, the chain of bags is only shown generally, and the details of the roof tiles described above are not shown.

In FIG. 1, the container 10 is illustrated with its top 20 fitted into its bottom 30 so that the top 20 can slide along the outside of the bottom 30 (not shown). The lower portion 30 is the first of the opposite, generally parallel, generally equal-sized side walls.
