Description

[Detailed Description of the Invention] "Industrial field of application" The present invention proposes, for example, that four-color cream products are separately stored in one tube container, and the four-color cream products are compressed by the body part. The present invention relates to a synthetic resin tube container provided so that both objects are poured out in a stripe shape.

"Prior art" A partition plate is vertically installed in the tube container body to form two chambers, and the lower end of the body is sandwiched around the lower end of the partition plate. There is a layer portion, and the left and right ends of the layer portion are welded to a plate-shaped seal portion forming a four-layer portion by bending a body portion forming wall in a W shape.

"Problems to be solved by the invention" In a tube container, the outer periphery of the shoulder member with a mouth and neck is welded to the upper end peripheral edge of the body, which is usually formed in a cylindrical shape, and the cap is screwed onto the mouth and neck. After filling the inside of the body from the lower end opening surface of the body with a creamy substance, the lower end of the body is clamped by a heating plate and sealed by welding. When the partition plate is provided in the body, since both sides of the partition plate 11 are continuous with the inner surface of the body 12 as shown in FIG. 5, the partition plate 11 is clamped when the lower end of the body is clamped.
The body tube wall portions 12a, 12a which are continuous with both sides cannot move to the left and right, so that the semicircular tube wall portions 12b, 12b before and after the partition plate partially bend.

In the above-mentioned conventional example, the refraction is performed on both the left and right sides of the partition plate, but if the heating plate is simply pressed from the front and rear of the lower end of the body part, the left and right sides of the partition plate as shown in FIG. It is difficult to always make the widths of the refraction portions 13, 13 evenly on the left and right sides, and the refraction is formed on only one of the left and right sides, or both side portions 14, 14 as shown in FIG.
Was two layers and only the intermediate portion 15 was three layers, and it was difficult to make the lower end of the body of each tube container the same shape.

In this plan, the conventional tube container with two chambers inside the body was expanded to four chambers, and by simply pressing the lower end of the body, the left and right ends were two layers of the same width, and the middle part was four layers. In addition, it is easy and reliable to uniformly form each tube container.

"Means for Solving the Problem" A synthetic resin tube container in which a partition plate is vertically installed in the container body 1 and the inside of the body is divided into a plurality of chambers with upper end openings,
The container main body has a circular cross-section, and a flexible cross-shaped partition plate 7 having a cross-section that is thinner than the wall of the body forming wall is vertically installed in the container main body to divide the partition. Each end of the plate portion 6 protruding in four directions is connected to the inner surface of the body forming wall to divide the inside of the body into four chambers, front and rear, and left and right. The parts 6 ... are positioned in a state of overlapping to the left and right, and the plate parts and the body part forming walls 2a, 2a of the front and rear chambers form a four-layered layer 8, and the left and right end parts of the left and right chambers. A welded plate-like seal portion 3 in which the body portion forming wall is in contact with the middle folding part and forms a two-layer shape 9 of the same width.
Formed.

[Operation] As shown in FIG. 1, when the lower end of the body is open, the body 2
After filling the inside with the creamy substance, the body forming wall portions 2a, 2a of the front and rear chambers are pressed by the base plates 10, 10 shown in FIG. 3, whereby the partition plate 7 having a cross-shaped cross section is thin and flexible. Because it has sex
By pressing the body forming wall portions 2a, 2a of both the front and rear chambers respectively in the direction of the center axis of the body, the lower end of the body becomes an ellipse that is long in the left and right, and the partition plate 7 is the tip of the plate portion 6 that projects left and right in the front and rear direction. The parts are deformed so that they approach each other. By further approaching the base plates 10 and 10, as shown in FIG. 2, the middle portion in the left-right direction is formed into four layers 8 by the body forming wall portions 2a and 2a of the front and rear chambers and the partition plate 6 ...
Both left and right ends can be transformed into a two-layered shape 9 in which the wall portions forming the left and right chamber bodies are bent in the middle, and as shown in FIG. 3, they are sandwiched by plywood 10, 10 and project above the sandwiched portion. A sandwiching plate in which the lower end of the body portion thus heated is heated by the heat source 11 and placed on the base plate.
By sandwiching the above-mentioned protruding portion at the tips of 12, 12, it is possible to form a plate-shaped welded seal portion 3 as shown in FIG. The welding may be performed by ultrasonic sealing.

The interior of the container is divided into four chambers by a cross-shaped partition plate.
Therefore, for example, four-color creamy products having different colors can be separately stored, and the four-colored storage products are continuously extruded by pressing the body portion 2.

[Example] A synthetic resin tube container main body 1 has a cylindrical and flexible body portion 2 whose bottom end is welded in a plate shape to form a seal portion 3, and a mouth and neck portion from a top end of the body portion to a shoulder portion 4 Standing up, the cap 5 is detachably fitted to the mouth and neck. The main body of the container is provided with a flexible partition plate 7 projecting the plate portions 6 in a cross-shaped cross section in four directions inside the container body by connecting the tip ends of the plate portions to the inner surface of the body portion forming wall and vertically installing the body. The interior is divided into four rooms, front and back, and left and right. The wall thickness of each plate portion was thinner than the wall forming the body portion, and the wall thickness of the plate portion was about 0.2 mm with respect to the wall thickness of the body forming wall of about 0.4 mm.

[Advantages of the Invention] The present invention is configured as described above, and the body 2 of the tube container main body has a circular cross section, and is flexible and has a thinner cross section than the wall of the body forming wall. A letter-shaped partition plate 7 is vertically installed in the container body, and each tip of the plate portion 6 projecting in four directions by the partition plate is connected to the inner surface of the body portion forming wall to divide the body portion into four chambers, front and rear and left and right. Therefore, by simply pressing the middle of the body forming wall portions 2a, 2a of the front and rear chambers in the direction of the center axis of the body,
The body forming walls of the left and right chambers are bent at their intermediate portions as shown in FIG. 2, and the plate portions 6 of the partition plate 7 are folded to the left and right for two sheets. At the lower end of the body part, at the middle part in the left-right direction, the plate parts 6 ...
A welded plate-like seal part in which a four-layered structure 8 is formed by a and 2a, and at both left and right ends, body forming walls of the left and right chambers are in contact with the middle folded part to form a two-layered structure 9 having the same width. 3 is easy, and since the two-layered 9 portions at both left and right ends of the seal portion 3 have the same width, the bending portion of the barrel lower end cylindrical wall is not uniform as in the above-described conventional example. Therefore, the appearance of the container is not damaged.

Further, as described above, since the body section cross-sections are deformed into a constant shape by pressing the body forming walls 2a, 2a of the front and rear chambers, even when the body section is squeezed for pushing out stored items, the body section By pressing the cylinder wall part, the middle part is deformed into four layers and the left and right ends are deformed into a cross-sectional shape with two layers, so that the body part can be squeezed easily, and therefore most of the stored items are left. It can be pushed out without.

Further, since the partition plate 7 is provided and the inside of the body is formed into four chambers, if stored items of different colors are put in each chamber and the parts are squeezed, the stored items of four colors are extruded from the mouth of the container body. As a result, the taste of the consumer can be met.
