Description

  The present invention relates to a technique for efficiently storing and transporting a thin-walled container formed integrally with a stopper having a handle.

As a conventional thin-walled container, for example, it is easy to pour out the contents by projecting the pour-out cylinder from the barrel portion that is filled with the contents. There is a thin-walled blow-molded container that makes it easy to separate the stopper (see, for example, Patent Document 1).
JP 2005-67705 A

  However, since these conventional thin-walled containers are thin-walled, for example, when attempting to increase the internal volume while further reducing the thickness, filling the contents causes the entire container to expand into a crushed shape. For example, it may be difficult to maintain the shape when it is independent. In this case, there is a problem that it is bulky during storage and transportation. For this reason, this inventor came to recognize the demand for the thin container effective in storage and conveyance.

  The present invention has been made on the basis of such fact recognition, and an object of the present invention is to provide a novel thin-walled container excellent in flowability and usability.

The thin-walled container according to the present invention is to be cut into a barrel portion that is filled with contents, a tapered shoulder portion that is connected to the trunk portion, a pour tube that stands up from the shoulder portion, and a tip opening of the pour tube. Having a plug body separably connected via a wire,
By folding the upper end of the body part inward and forming a folded part connected to the shoulder part, the shoulder part can be recessed into the body part,
A reinforcing portion having an air layer and extending in the axial direction is provided on at least two opposite side surfaces of the body portion.

  The reinforcing part is preferably extended to the same position as the folded part. In addition, it is preferable that the reinforcing portion has a shape that spreads outward toward the shoulder.

  In addition, examples of the thin container according to the present invention include various containers such as a thin blow molded container and an injection molded container.

  According to the present invention, if the plug body is pushed into the trunk portion together with the shoulder portion via the folded portion, the plug body is housed inside the trunk portion together with the shoulder portion, so if the entire container is inverted, The folded portion can be made independent as a seat portion. Thereby, since the plug body can stand on its own without protruding from the body portion, the container can be made compact. For this reason, according to the present invention, it is difficult to be bulky during storage, transportation, display, etc., and space can be effectively utilized.

  In addition, according to the present invention, the strength on both sides of the body portion is improved by providing the reinforcing portion having an air layer and extending in the axial direction on at least two side surfaces facing the body portion. Therefore, even if it is self-supporting in a state where the contents are filled, it becomes a highly shape-retaining container in which the body portion is hardly crushed.

  Moreover, when using as a container, if a plug body is pulled out from the trunk | drum with the bottom part, a pouring cylinder can be stood up from a shoulder part. For this reason, the contents can be easily taken out as in the prior art.

  Therefore, according to the present invention, it is possible to provide a novel thin-walled container excellent in flowability and usability.

  By the way, when a large-capacity internal solution is stored in the trunk portion, the self-supporting property can be maintained by the presence of the reinforcing portion. In other words, when the trunk portion sinks due to filling of the contents when the folded portion is made to stand by itself as the seat portion, the reinforcing portion becomes the seat portion together with the folded portion. For this reason, the reinforcement part does not necessarily need to extend to the same position as the folded part.

  On the other hand, if the reinforcing portion is extended to the same position as the folded portion, the reinforcing portion becomes a seat portion together with the folded portion regardless of the state when the contents are filled. For this reason, if a reinforcement part is extended to the same position as a folding | returning part, the self-supporting performance when a container is inverted and a folding | returning part is made into a seat part can be improved.

  Furthermore, if the reinforcing portion has a shape that spreads outward as it goes toward the shoulder, the stability when the folded-back portion is self-supporting as a seat portion is improved. That is, even when the reinforcing portion has a shape that spreads outward toward the shoulder portion, the self-supporting performance when the container is inverted and the folded portion is the seat portion can be improved. Further, if the reinforcing portion has a shape that spreads outward toward the shoulder portion, it can be easily carried because the folded portion is easy to grip in the seat portion.

It is the side view and bottom view of the container 1. Moreover, FIG. 5 is a front view partially showing a state where the thin container 1 is made compact and self-supporting.

  As shown in FIGS. 2 and 3, the thin-walled container 1 is connected to the trunk portion 2 filled with the contents, the shoulder portion 3 that is tapered along the trunk axis O, and the shoulder portion 3. A barrel portion together with a pouring cylinder 4 standing along the trunk axis O and a plug body 6 that is detachably connected to a leading opening of the pouring barrel 4 through a planned cutting line 5 formed as a thin portion. The bottom part 8 is formed by blow-forming integrally the reinforcement part 7 extended to two opposing 2 side surfaces, and heat-sealing to the lower end.

  In this embodiment, the upper end of the body part 2 is curved inward of the body part 2 to form an annular folded part 2a so as to surround the body part axis O, and the body part 2 is formed via the folded part 2a. Connect to shoulder 3. As a result, if the shoulder 3 is pushed into the body 3 along the body axis O, the shoulder 3 is moved along the body axis O as shown by the broken lines in FIGS. It can be reversed and depressed toward the inside of the part 3.

  According to such a configuration, the amount of depression of the shoulder portion 3 with respect to the trunk portion 2 is appropriately set according to the height of the folded portion 2a to the handle 6a, etc., so that the dispensing tube 4 sealed with the plug body 6 is provided. As shown in FIG. 5, the plug body 6 can be housed inside the trunk portion 3 through the folded portion 2 a.

  Further, as shown in FIG. 2, the reinforcing portion 7 extends along the axis O, and is continuous along a ridge line along the axis O of the container body 2 when the trunk portion 2 is viewed from the front surface. It will be extended to. As shown in the XX cross section, the reinforcing portion 7 according to the present embodiment includes a tubular air frame 7a having an air layer 7r formed therein, and a thin-walled connecting portion that connects the air frame 7a to the body portion 2. 7b.

  If the reinforcement part 7 is provided, it will become difficult to deform | transform when the said trunk | drum 2 is hold | gripped by obtaining fixed rigidity (strength) with respect to the thin-walled trunk | drum 2. FIG. For this reason, it becomes easy to pour the contents by providing the reinforcing portion 7. Further, the reinforcing portion 7 can also function as an auxiliary handle portion when the plug body 3 is separated.

  The air frame 7a is not limited to a circular cross section, and may have various cross-sectional shapes such as a square cross section and a triangular cross section (these vertices or sides can be connected to the connecting portion 7b). . Further, as in the present embodiment, when the bottom portion 9 is formed by filling the body portion 2 with the internal solution and then heat sealing, the reinforcing portion 7 having the air layer 7r is simultaneously provided on the two opposing side surfaces of the body portion 2. be able to.

That is, according to the thin-walled container 1 of this embodiment, when the plug body 6 is pushed into the body portion 2 together with the shoulder portion 3 through the folded portion 2a, the plug body 6 is brought into the body portion 2 together with the shoulder portion 3. since the housing, if the inverted the entire container, as shown in FIG. 5, the folded portion 2a can be self-supporting as a seat portion S _1. Thereby, since the plug body 6 can stand on its own without protruding from the body portion 1, the thin container 1 itself can be made compact. For this reason, according to the thin container 1 of this embodiment, it is difficult to be bulky during storage, transport, display, etc., and effective use of space can be achieved.

  In addition, according to the thin-walled container 1 of the present embodiment, the reinforcing portion 7 having the air layer 7r and extending in the direction of the axis O is provided on the two opposing side surfaces of the trunk portion 2, so that the trunk portion 2 Since the strength on both sides is improved, even if the contents are filled and self-supported, it becomes a highly shape-retaining container in which the body 2 is not easily crushed.

  Further, when used as a container, if the extraction tube 4 together with the stopper body 6 is pulled upward along the trunk axis O and pulled out from the trunk section 3, as shown in FIGS. The pouring tube 4 can be erected. For this reason, if the handle 6a of the plug body 6 is grasped and cut along the planned cutting line 5 after the dispensing cylinder 4 is pulled up, the contents can be easily taken out as in the conventional case.

  Therefore, according to the thin-walled container 1 of this embodiment, a novel thin-walled container excellent in flowability and usability can be provided.

By the way, when a large volume of the internal solution is stored in the body portion 2, the presence of the reinforcing portion 7 can maintain the self-supporting property. That is, the reinforcing portion 7, when brought into freestanding the folded portion 2a as the seat S _1, if the sunken is barrel 2 by filling the contents, the seat S ₂ together with the folded portion 2a.
