Description

[Detailed Description of the Invention] "Industrial application field" The present invention proposes, for example, that three-meal creamy products are separately stored in a single tube container, and the three-meal creamy products are then compressed by body squeezing. The present invention relates to a synthetic resin tube container provided so that objects can be poured together.

"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 thereof are welded to a plate-shaped seal portion having a four-layer portion in which a body forming wall is bent 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 make the widths of the refraction portions 13 and 13 always uniform evenly on the left and right sides, and the refraction is formed only on one of the left and right sides, or 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.

This proposal increases the number of tube containers with two chambers in the body part, which has been done in the past, to three chambers, and by simply pressing the lower end of the body part, the left and right ends are a two-layer portion with a uniform horizontal width, and the middle part is four layers. The part is provided so that it is easy and reliable to uniformly form each tube container.

"Means for Solving the Problem" In a tube container made of a synthetic resin in which a partition plate 6 is vertically installed in the container body and the inside of the container is divided into a plurality of chambers with an upper end opening, the container body barrel 2 has a circular cross section. At the same time, the partition plate 6 is formed so as to project from both side wall portions 2a, 2a at the front and rear of the arbitrarily defined body portion in the direction of the center of the body portion symmetrically with the both side wall portions opposing the partition plate, The lower end of the body portion is a welded plate-like seal portion 3 in which the middle portion in the left-right direction has four layers 7 and the left and right end portions following the four-layer portion form two layers 8 with the body forming wall in contact with the folded back. Formed.

[Operation] As shown in FIG. 1, the lower end portions of both side wall portions 2a, 2a in front of and behind the body portion facing the rear partition plates 6 and 6 in which the body portion 2 is opened and the creamy substance is filled into the body portion 2. When the middle of the outer surface is pressed by the heating plate, the partition plate 6 and the side wall portion 2a facing the partition plate are formed so as to project symmetrically, so that the lower end of the body is first deformed into an elliptical shape elongated in the left-right direction, and then From the curved state where the middle parts of the partition plates 6 and 6 are in contact with each other and the partition plates 6 and 6 also project inward of the body part, like the front and rear side wall parts 2a and 2a, gradually extend in a straight plate shape. Also, as they are extended in the shape of a straight plate, the middle part of both left and right side wall parts, except for the both side wall parts 2a, 2a, will also be bent, and further, the front and rear space of the lower end of the body part will be sandwiched by both heating plates. And, by sandwiching it, the lower end of the body part should be the seal part 3 welded in a plate shape as shown in FIG. Can.

Since two partition plates 6 and 6 are provided in the container body, it is divided into three chambers, for example, it is possible to separately store three kinds of creamy products of different colors, and by pressing the body 2 The three-colored items will be continuously extruded.

[Example] A synthetic resin tube container body 1 has a cylindrical and flexible body 2 with a plate-shaped lower end to form a sealing portion 3, and a mouth / neck portion is erected from the upper end of the body through a shoulder 4. Then, the cap 5 is detachably fitted to the mouth and neck.

Two flexible partition plates 6, 6 are vertically installed in the container body, and both sides of each partition plate are connected to the inner wall surface of the container body.

As shown in FIG. 2, the partition plates 6 and 6 are provided with the both side wall portions facing the partition plate in the direction of the center of the body from the side wall portions 2a, 2a before and after the body portion 2 which are arbitrarily determined. An eye shape in which two arcs having the same curvature and the same length are opposed to each other and both ends thereof are connected to each other is formed so as to project symmetrically.

The formation of the seal portion 3 at the lower end of the body portion 2 is performed as described above.
As shown in FIG. 3, with the lower end portion sandwiched by the heating plates, the middle portion in the left-right direction is four layers 7, and the left and right end portions continuing to the four-layer portion are shown in FIGS. Is formed into a plate-like shape in which the body forming wall is in contact with the folded back to form the two layers 8, and the plate-like portion is directly welded to form the seal portion 3.

As shown in FIG. 1, the seal is formed by capping the neck portion of the container main body, inclining the container upside down, and filling the contents into the respective chambers through the opening at the lower end of the body. Seal on.

[Advantage 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 a partition plate vertically installed in the body.
6, 6 from the both side wall portions 2a, 2a before and after the body portion which are arbitrarily determined, in the direction of the center of the body portion, on both side wall portions 2 facing the partition plate.
Since it is formed to project symmetrically with a and 2a, when the lower end of the body is welded into a plate shape, pressing the outer surface of the intermediate portion of the both side wall portions 2a and 2a causes the lower end of the body to first become an elliptical shape that is long in the left-right direction. It is deformed, and then the middle part of the partition plates 6,6 contact and the partition plates 6,6
Also, from the initial curved state of overhanging to the inside of the trunk, like the above-mentioned front and rear side wall portions 2a, 2a, it will be gradually extended into a straight plate shape, and as they are extended into a straight plate shape, both side wall portions will be expanded. Except for 2a and 2a, the middle portions of the left and right side wall portions are also bent. Therefore, as shown in FIG. 3, the middle portion in the left and right direction is four layers 7 and the left and right end portions following the four layer portions are body portions. It becomes easy and reliable to form the welded plate-like seal portion 3 in which the forming wall is in contact with the folded back and forms two layers, and if the bending portion of the barrel lower end cylindrical wall is uneven as in the conventional example described above. It never happens.

Further, as described above, since the body cross section is deformed into a constant shape by pressing both side wall portions 2a, 2a on the front and rear of the body, even when the body is squeezed for pushing out stored items, By pressing the cylinder wall part, the middle part has four layers as described above, and the left and right ends are deformed into a cross-sectional shape with two layers, so that it is easy to squeeze the body part, and therefore almost nothing is stored. Can be pushed out.

Furthermore, since the partition plates 6 and 6 are provided to form the inside of the body into three chambers, if the contents of different colors are put in each room and the body is squeezed, the three-colored contents will be pushed out from the mouth of the container body. As a result, the consumer's taste can be dealt with.
