Abstract

(57) [Summary] [Purpose] The technical problem is to prevent the occurrence of overall elastic deformation of the head in a tube application container, and leakage of contents from between the head and the application stopper and the head. This is to prevent the application plug from coming out of the part. [Structure] A reinforcing cylinder 3 having high rigidity is tightly and immovably fitted into a head 2 which is adhesively fixed to a tube 1, and a coating plug is provided in an assembled portion of the head 2 and the reinforcing cylinder 3. By tightly and tightly assembling and assembling 4, the reinforcing cylinder 3 surely prevents the elastic deformation of the head 2 as a whole due to the pressing force acting on the tube 1 when the contents are poured out. Therefore, the leakage of the contents and the escape of the coating stopper are prevented, so that the tube coating container can be used safely.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tube-shaped coating container having a feature of an assembly structure of a tube container and a coating stopper.

[0002]

[Prior art]

 A so-called tube coating container, in which a coating stopper is attached to the head of the tube container, is widely used.

In this container, the contents are poured out from a coating stopper by pressing the tube portion of the tube container and directly applied to the affected area or the like.

A conventional tube coating container is configured by adhesively fixing a head portion to an upper end opening of a tubular tube having a bottom, and fitting and assembling a coating plug on the head portion.

[0005]

[Problems to be solved by the device]

 In this conventional tube coating container, there was a problem that there is a risk that the contents may leak between the head and the coating stopper during use, or the coating stopper may come off the head. .

This is due to the fact that the head must be molded with a slightly soft resin in consideration of the adhesiveness with a soft tube.

That is, when the tube portion is pressed for pouring out the contents, the pressing force causes the head part made of a slightly soft resin to be elastically deformed as a whole, and the head portion formed by the fitting and assembling. If a gap is formed between the gaps and the contents leak out from this gap or the elastic deformation is large as a whole, the coating stopper will come off due to the large internal pressure of the tube container.

In particular, when the remaining amount of the content becomes small and the head area is strongly pressed, such a problem is likely to occur.

Therefore, the present invention was devised to solve the above-mentioned problems in the prior art. Therefore, it is possible to prevent the head portion of the tube container from being elastically deformed as a whole by the pressing operation for pouring out the contents. It is a technical issue to prevent this, and even if the tube part of the tube container is pressed, the contents do not leak from between the head and the application stopper, and the application stopper does not come off. The purpose is to provide a container.

[0010]

[Means for Solving the Problems]

 Means of the present invention for solving the above technical problem is to have a tube made of a soft resin material having a cylindrical shape with a bottom, to have a head made of a slightly soft resin material adhered to this tube, In order to strengthen the rigidity of the head part, it is necessary to have a high-rigidity reinforcing tube that is tightly fitted to the inner peripheral surface of the head and cannot be slipped out. It has a coating plug that is firmly inserted and assembled.

[0011]

[Action]

 When the amount of contents in the tube is low and the area near the head is pressed hard, the head made of soft resin tends to elastically deform as a whole due to this pressing force.

However, since the stiffening cylinder having a high self-shape retention ability is densely and immovably attached to the inner peripheral surface of the head, the stiffening cylinder has a high rigidity. Global elastic deformation of the head is prevented.

Therefore, it is possible to prevent the leakage of the content between the head and the coating plug or the removal of the coating plug from the head, which is caused by the overall elastic deformation of the head. .

Since the application plug is tightly and firmly fitted and assembled in the assembling part of the reinforcing cylinder and the head, which does not cause the elastic deformation as a whole by the pressing force acting on the tube, the pressing force is increased. Regardless of the presence or absence of the action of, the dense and strong assembling state of the assembling portion of the reinforcing cylinder and the head can be stably maintained.

【Example】

 FIG. 1 shows an embodiment of the present invention, in which a tube 1 made of a soft resin material having a closed bottom and made of a soft resin material has a cylindrical head at the upper end opening. 2 is bonded, and a cylindrical resin-made reinforcing cylinder 3 having a high rigidity is tightly and immovably fitted in the head 2, and the application plug 4 is tightly and firmly fixed to the reinforcing cylinder 3. It is fitted and assembled.

The two locking ridges 7 projectingly provided on the outer peripheral surface of the reinforcing cylinder 3 bite into the inner peripheral surface portion of the head 2 so that the reinforcing cylinder 3 is dense and does not come out of the head 2. We are making sure to achieve and maintain the impossible assembly.

In addition, the seal projection 8 provided around the upper part of the inner peripheral surface of the reinforcing tube 3 is set by setting the tight fitting of the coating plug 4 into the reinforcement tube 3 to the seal projection 8 portion. The tight and firm fitting of the coating plug 4 to the reinforcing tube 3 is surely achieved.

In the illustrated embodiment, the inner flange of the head 2 is provided around the upper end of the head 2 so that the inner peripheral edge of the head 2 is in close contact with the outer peripheral surface of the coating stopper 4. The piece is intended to reinforce the tight assembly of the application plug 4 with respect to the assembly part of the head 2 and the reinforcing cylinder 3, and the fitting limit of the reinforcing cylinder 2 from the bottom to the head 2 Is set.

[0019]

EFFECTS OF THE INVENTION As described above, according to the present invention, since the reinforcing cylinder having a high rigidity is densely and immovably attached to the slightly soft head, the entire elastic deformation of the head is prevented. It is said that the contents are leaked between the head and the applicator plug or the applicator plug is pulled out from the head due to the elastic deformation of the head as a whole. It is possible to reliably prevent the occurrence of problems.

This can be carried out simply by inserting and assembling a highly rigid reinforcing cylinder formed into a simple cylindrical shape into the head of a general tube container composed of a tube and a head. is there.
