Description

The present invention relates to a retort pack for storing and storing curry or stew.

Conventional retort packs (hereinafter referred to as packs) are opened by right-handed people by holding the lower part of the cut in the upper part of the pack with the index finger and thumb of the left hand, and holding the pack with the remaining finger and belly of the hand Then, grab the upper part of the cut with the index finger and thumb of your right hand, open it away from your right and left, and tear it open as you pull the film on the right hand side.

Japanese Patent Application No. 2007-240148

In Patent Document 1, yarn is bonded to the surface of a retort pack and the pack is opened. The cost is increased because a separate work process such as yarn bonding is required.

The state of the film material as a result of a series of cutting operations for opening the pack is as follows.
1. Cutting begins at the cut end where the two front and back film materials on one end are sealed and become the thickness of the two film materials.
2. While cutting separate film materials one by one on the front and back sides of the storage section, the cutting head reaches the inner end of the other end seal section at a right angle.
3. The cutting head part is cut again and the seal part on the other end side where the film material thickness becomes two sheets is cut and opened.

Conventionally, the cutting head portion of 2. described above reaches the inner end of the seal portion on the other end side at about a right angle. The cutting force of the leading portion transmitted to the two front and back film materials is dispersed in the vicinity of the peripheral portion of this reaching point, and the cutting force is weakened due to the weakening of the concentration force, making it impossible to cut the film material.

When you reach step 2 above, it is often impossible to break the film material by applying considerable force. Since the cutting of the pack is not completed, stew or curry adheres to the uncut pack pieces when the hot water is transferred to the tableware.

In the state of 2. above, even if force is applied to the left and right hands holding the pack, the cutting head will not stop at the inner end of the seal part and will not break. If you try to tear it, the pack will suddenly break and the contents will scatter and stain the surroundings, or hot and sticky contents may stick to your fingers and body.

If the pack cannot be cut, even if you give up opening from one end and start cutting again from the cut end on the other end, you will not be able to cut the pack piece. Washing with water is required.

According to the present invention, the consumer is not confused by opening the same opening operation as before. The manufacturer initially requires a facility cost for the pack sealing process, but provides a pack that solves the above-mentioned problems in the same process as before.

The easy-open bag according to claim 1 is a bag body in which two film materials which are front and back are combined, the periphery is sealed, and the stored items are filled inside. At least one cut edge that is easy to start cutting is provided on the outer edge above the seal part of the bag body, and a substantially V-shaped and serrated inner notch in the vicinity of the inner end side (seal part inner end) of the storage part of the cut end A valley and an inner notch are provided.

The easy-open bag of the present invention includes a bag body in which a film material is folded in half and sealed in three directions, a bag body having a gusset (gather), and a bag body in which the upper and lower sides of a cylinder are sealed.

The easy-open bag according to claim 2 is the easy-open bag according to claim 1, wherein an upward notch is provided on the lower side of the inner notch valley provided at the inner end of the storage portion.

The easy-open bag according to claim 3 is the easy-open bag according to claim 1 or 2, wherein the easy-open bag is located at the upper corner of the inner end notch valley provided at the top of the inner end of the storage portion. A corner notch is provided.

According to the present invention, consumers are not confused by the conventional opening method, and worried about the scattering of hot contents, sticking to the human body, and burns even in the elderly and children who have become weak. It is easy to cut and open the pack, and the food manufacturer can make a bag in the same manner as before.

1 to 2 show an easy-open bag 1 in which an embodiment of the present invention is adopted.

As shown in FIG. 1, the easy-open bag 1 has a structure in which two front and back film materials 8 are joined together, the periphery of which is a seal portion 7, and the inside becomes a storage portion 6, which includes curry, stew, powder, and the like. It is a bag that can be stored. A cut opening 2 is provided at the upper outer edge of the easy-open bag 1 so that it can be easily cut without applying force when the pack is opened. On the inner end side (seal portion inner end) of the storage portion 6 in the vicinity of the cut end 2, a serrated and substantially V-shaped inner end notch mountain 4 and an inner end notch valley 3 are provided above the inner notch valley 3. An upper corner notch 9 is provided at the corner.

The series of operations for opening the pack starts twisting and cutting so that the cut 2 provided at the outer edge of the seal portion 7 on one end side is twisted with the index finger and thumb of both hands as the border. The cutting force is concentrated on one point corresponding to the valley of the cut 2 and the cutting starts easily. Opening both hands back and forth with a pack, the cutting top part is the sealing part on the other end side while cutting the two front and back film materials 8 of the storage part 6 in which the contents are stored. 7 reaches around the notch 4 of the inner end, and is guided to the bottom of the notch valley 3 of the inner end along the substantially V-shaped shape.

By providing the inner end notch valley 3, the cutting force is concentrated at one point of the valley portion as in the case where the cutting of the cut end 2 is started. Similarly to the time when the cutting of the initial cut 2 is started, the inner end notch valley 3 is twisted and twisted by the two film materials 8 on the front and back sides, and the force is concentrated on one point of the bottom of the valley portion. The two front and back film materials 8 at the top of the cut are twisted and pulled in the opposite direction by about 180 degrees with the bottom of the inner end notch valley 3 as a boundary, so that the force is concentrated on one point of the inner end notch valley 3. In this way, the seal portion 7 at the other end is easily cut in the same manner as the cut end 2 in the same manner as when the twist cut starts so as to be twisted with the index finger and thumb between both hands.

In the present invention, the reaching point on the inner end side of the storage portion of the cutting head portion is the inner end notch valley 3, so that the cutting force is concentrated at one point of the valley portion, and the pack is easily cut and opened.

Although the inner notch 4 and the inner notch 3 are greatly shown in the drawing, it is sufficiently effective to have the same size as the cut end 2 in terms of strength such as transportation of the easy-open bag 1. Can be obtained.

When the cutting head part reaches the inner end of the storage part, when the pack is not cut horizontally for some reason, the force applied in the lateral direction of the pack piece to be cut is directed upward notch 5, By sequentially cutting into the corner notches 9, the pack is opened with a small force. In this case, stress is concentrated on the valley portion of the upward notch 5 and the valley portion of the upper corner notch 9, so that cutting becomes easy.

The figure showing the easily openable bag of this invention. The upper partial figure of the easily openable bag of this invention.
