Description

The present invention relates to a distribution package capable of drawing pictures, characters, etc. satisfactorily using a stored item such as ketchup or chocolate.

Conventionally, some foods such as hamburgers, hot docks, and salads sold at fast food stores and convenience stores are attached with a distribution package in which seasonings such as mustard, ketchup, sauce, dressing, and jam are sealed and stored. There is something.

In these distribution packages, seasonings and the like are sealed and stored, and an opening is formed by bending a hard and flat lid member into a V shape to extrude a desired amount of the stored items such as the seasonings. It has a structure, and various studies have been made on such a distribution package.

For example, Patent Document 1 states that a rigid lid member that can be bent along a half-cut having a protruding discharge port forming portion as a break region in the central portion of the surface and a peripheral edge portion fixed to the back surface of the lid member. In a distribution package in which a storage portion made of a flexible member is provided to form a storage portion leading to a break region of the lid member, the tip portion of the discharge port forming portion has a substantially pyramid shape having ridges in all directions and is the same as the half cut. The lower half of the ridgeline on the line has a shape that is orthogonal to one end of a substantially rectangular parallelepiped protrusion, and a half cut is formed on the plane and vertical surface of the substantially rectangular parallelepiped protrusion on the same line as the half cut. The distribution package is disclosed, and the shape of the protruding discharge port forming portion on the surface of the lid member is a shape that can be expanded as a wide discharge port when the lid member is bent. It is said that even if a solid substance having a large diameter is contained, it can be smoothly extracted without clogging the discharge port.

Further, in Patent Document 2, when the lid member is bent toward the back surface side from the folding curve, a plurality of discharge port forming portions are each broken along the half cut, and the hollow portions thereof are on the front surface side of the lid member. In a distribution package configured to form a bellows-like discharge opening in the lid exposed to the lid, the plurality of ridges are formed from the vicinity of one end of the lid in the left-right direction to the vicinity of the other end. A pair of front and rear middle side discharges, which are arranged between a pair of front and rear long side discharge port forming portions and a pair of front and rear long side discharge port forming portions, and have a shorter overall length than the long side discharge port forming portions. From at least one set of the middle side discharge port forming portion composed of the outlet forming portion and at least one set of the middle side discharge port forming portion and at least between the long side discharge port forming portion and the middle side discharge port forming portion. Also has a pair of short-side discharge port forming portions with a short overall length, and the long-side discharge port forming portion, the middle-side discharge port forming portion, and the short-side discharge port forming portion are point-symmetric with respect to the middle point of the half cut. Distributing packaging characterized by being arranged in such a manner is disclosed, the overall bending rigidity of the lid member can be increased, and the lid can be easily closed even if the lid is pressed during transportation or handling. Since it does not deform, the half-cut is not easily cracked, and the sealing of the stored items is not impaired.

By locating the discharge port forming portion 11 between the center line in the lateral direction and the end portion in the lateral direction in this way, the position of the discharge port can be easily grasped, and the stored object stored in the storage portion 20 is pushed out. At that time, it becomes easier to draw pictures and characters. Further, in order to make it easier to grasp the position of the discharge port more effectively, the distance A between the end portion in the lateral direction of the lid member 10 near the position of the discharge port forming portion 11 and the discharge port forming portion 11 is set. It is preferably 1/10 or more and 1/3 or less, and more preferably 1/8 or more and 1/4 or less with respect to the dimension M of the lid member 10 in the lateral direction.

[Dimensions of discharge port forming part]

Further, the dimension C of the discharge port forming portion 11 in the lateral direction is preferably 4 mm or more and 15 mm or less. By adjusting the dimension B in the longitudinal direction of the discharge port forming portion 11 as described above, the lid member 10 is bent in a V shape via the half cut 12, and the discharge port forming portion 11 is cracked to form the discharge port. When it is used, it can be easily cracked.

[Apex angle and height of discharge port forming part]
Figure 4 is an enlarged view of the vicinity of the discharge port formation portion 11 of the _Y 1 -Y ₁ section of FIG. In the distribution package 1 of the present invention, the apex angle θ of the triangular vertical cross section of the discharge port forming portion 11 formed by the half cut 12 is an acute angle of 10 degrees or more and 30 degrees or less, and further 15 degrees or more and 28 degrees. The temperature is preferably 18 degrees or more, and more preferably 25 degrees or less. By adjusting the apex angle θ of the triangular vertical cross section of the discharge port forming portion 11 in this way, it is possible to prevent the stored items from dripping when drawing a picture, characters, or the like using the stored items, and the stored items can also be prevented from dripping. Can be prevented from being clogged in the discharge port, and a distribution package 1 in which characters, pictures, etc. can be drawn more easily can be obtained. In addition, on the premise that the requirements are satisfied, in order to make it easier to draw characters, pictures, etc., the height D in the vertical direction from the front plane of the lid member 10 to the apex having the apex angle θ is 1. It is preferably 5 mm or more and 2.5 mm or less, and more preferably 1.8 mm or more and 2.3 mm or less.
