Description

  The present invention relates to a tube container, and more particularly, to a tube container in which the contents accommodated in the tube container do not remain.

Many such tube containers have been proposed in the past, and for example, there is a tube container disclosed in Japanese Utility Model Publication No. 53-524 (see Patent Document 1). As a tube container similar to this, there has conventionally been a tube container shown in FIGS. The tube container shown in FIG. 8 includes a head portion 31 having an opening 30, a shoulder portion 32 that is uniformly inclined downward from the head portion 31, and a body portion that accommodates contents that continue below the shoulder portion 32. 33, a sealing lid 34 is fitted into the opening 30, and the surface near the bottom of the shoulder 32, that is, the surface of the upper end position of the body 33, runs parallel to the opening 30. A ring-shaped groove 35 is formed (a half-moon-shaped concave groove is disclosed in Patent Document 1). That is, it becomes easy to bend the trunk portion 33 along the groove 35, and the pushability of the contents at the final stage is improved. FIG. 9 shows a state where the sealing lid 34 is not attached to the opening 30 of the tube container of FIG.
Japanese Utility Model Publication No. 53-524 (page 1-2, Fig. 2)

  In the above conventional example, the head 31 and the shoulder 32 are formed with male threads for tightly sealing the contents, and the thickness is increased to maintain the strength for attaching the cap. There is a drawback that the contents remain in the shoulder portion 32 even after all the contents in the trunk portion 33 are pushed out. In order to squeeze the thick shoulder portion 32 by hand and push out all the contents remaining in the shoulder portion 32, a large finger force is required, which is extremely difficult for elderly people, women and children. It was a thing. Further, discarding the contents in the shoulder 32 while remaining has a disadvantage that resources are wasted. The present invention has been made paying attention to such a problem, and an object of the present invention is to provide a tube container in which the entire contents can be easily pushed out and the contents do not remain in the tube container.

A tube container according to the present invention includes a barrel portion that contains contents, a horizontal portion that extends inward from the tip of the barrel portion, closes the tip, and is formed thicker than the barrel portion, and a cylindrical head portion extending from near the center of the horizontal portion upward, the external thread formed on the outer periphery of the head portion, in the body portion and the horizontal portion and the head and is made of metal, and they are integrally molded The trunk portion immediately below the horizontal portion is provided with a groove that runs parallel to the horizontal portion, and the groove is recessed inward only on the outer surface side of the trunk portion. To do. Here, the groove is not particularly limited. However, the groove may be formed continuously over the entire circumference of the body portion, or the flat groove is intermittently provided at intervals as in the invention of claim 3. It may be formed automatically. With this configuration, the body can be easily bent along the groove, the contents can be easily pushed out, and the tube container does not have a conventional inclined so-called shoulder. Since it becomes a horizontal part, it becomes possible to extrude the content in a trunk | drum completely, and it can prevent reliably leaving the content in a tube container.

  According to the present invention, the body portion is formed along the groove by forming a horizontal portion at the front end of the body portion of the tube container and providing a groove that runs parallel to the horizontal portion in the body portion near the horizontal portion. It can be bent easily and the contents can be pushed out easily, so even if the remaining amount of the contents becomes small, anyone can easily complete the contents in the torso with just a moderate force Can be extruded. In addition, since there is no shoulder in the tube container, it is possible to reliably prevent the contents from remaining in the tube container in combination with the above-described effects, and to provide a tube container having an excellent commercial value. .

  The purpose of preventing resources from being wasted is realized by the synergistic action of the horizontal part formed at the front end of the body part and the groove formed in the body part.

FIG. 1 shows Reference Example 1 of the present invention. A tube container of this example includes a head 2 for taking in and out the contents, a trunk 3 for containing the contents, and a head of the trunk 3. It is comprised from the horizontal part 4 which protruded horizontally to the side in the edge part 2 side. The head 2 has a cylindrical shape, and a male screw 5 that is screwed with a cap lid (not shown) is screwed on the outer peripheral wall. Further, a recess 7 having an inner diameter greater than or equal to the inner diameter of the opening 6 of the head 2 and less than the outer diameter of the head 2 is formed on the upper end. A sealing lid 8 is fitted to prevent the contents from coming into contact with the outside air or the like. The trunk | drum 3 is carrying out the inner cylinder shape, and the lower end part is crushed in flat shape, and is sealed by bend | folding double or triple toward the head 2. FIG. In addition, a single ring-shaped groove 9 is formed immediately below the horizontal portion 4, that is, on the outer peripheral wall at the upper end position of the body portion 3. Shape the groove 9, is provided a recess inwardly only in the outer peripheral wall, the location in which to mold the thin-walled (not shown). Incidentally, the tube container to which the present invention is applied is a metallic tube.

FIG. 2 shows Reference Example 2 of the present invention , which is different from Reference Example 1 in that it is located in the vicinity immediately below the ring-shaped groove 9 formed in the outer peripheral wall at the upper end position of the body portion 3. One groove 9 having the same shape is formed, and two grooves are formed on the outer peripheral wall of the body portion 3. The two grooves 9 and 9 are formed in a bellows shape at equal intervals from the horizontal portion 4 in the vertical direction. As described above, by providing the two grooves 9 and 9 at the upper end position of the body part 3, the flexibility of the body part 3 is improved, and the body part 3 can be easily crushed even with a small force.

FIG. 3 shows Reference Example 3 of the present invention. The difference from Reference Example 1 is that flat grooves 10 are intermittently formed on the outer peripheral wall at the upper end position of the body portion 3 at a predetermined interval. This is the point. As in Reference Example 1, the body 3 can be easily bent without necessarily providing the groove continuously, and the contents can be easily pushed out. The shape of the groove is not necessarily a flat groove, and may be a circular groove (dimple shape) or the like.

FIG. 4 shows Reference Example 4 of the present invention. The difference from Reference Example 1 is that a recess 7 for fitting a sealing lid 8 is not formed at the upper end of the head 2 and the head The upper end of 2 is directly the opening 6. By comprising in this way, when a cap lid | cover is removed, a content can be extruded and used immediately without passing through another operation | work.

FIG. 5 shows Reference Example 5 of the present invention. The difference from Reference Example 4 is that there is another one in the vicinity immediately below the ring-shaped groove 9 formed in the outer peripheral wall at the upper end position of the body portion 3. The groove 9 having the same shape is formed, and two grooves are formed on the outer peripheral wall of the body portion 3.

Such a head 12 is engaged with a cap 20 as shown in FIG. A fitting cylinder 22 is formed inside the cap 20, and a plurality of locking pieces 23 separated by vertical slits are formed at the lower end of the fitting cylinder 22. A needle body 25 is formed on the top surface. Then, by pressing the outer peripheral cylinder 24 of the cap 20, the engagement between the protrusion 12 b of the head 12 and the locking piece 23 is released, and the cap 20 can be removed from the head 12. The tube container can be opened by punching the sealing lid 18 with the needle body 25. Further, when the cap 20 is attached, the locking piece 23 is elastically engaged with the protrusion 12b of the head 12 simply by inserting the cap 20 into the head 12 and lightly pressing the top surface of the cap 20. To do. The configuration in which one ring-shaped groove 19 is formed immediately below the horizontal portion 14, that is, on the outer peripheral wall at the upper end position of the body portion 13, is the same as in the other embodiments. Two or more grooves 19 can be formed (not shown).

  As an application example of the present invention, the barrel can be easily bent along the groove, the contents can be easily pushed out, and the tube container has no conventional inclined so-called shoulder and is horizontal. Therefore, if the contents are very expensive drugs, etc., the contents are not left in the tube container. Can be used up completely, so it is not wasted. Moreover, since the contents can be used up even by children, elderly people, etc., it is useful in the field of effective use of resources.
