Abstract

PROBLEM TO BE SOLVED: To provide a tube container capable of reducing the contents remaining in its neck. SOLUTION: The tube container 1 comprises a tube main body 2 and a hinge cap 3. The tube main body includes a body 4 for accommodating the contents, a shoulder 5 that closes the upper end of the body 4, a neck 6 having an opening 7 defined therein. The hinge cap 3 is attached to the neck 6 of the tube main body 2 and is formed from a lid main body 8 and an upper lid 9 that are integrated via a hinge 10. In the tube container 1, the neck 6 of the tube container 2 is low in height and L-shaped grooves 6 are formed in the peripheral edges of the neck. Projections 11 of the hinge cap 3 is vertically fitted in the L-shaped grooves 6a and thereafter the hinge cap 3 is turned in the axial direction. Thus, the projections 11 are guided in and engaged with the L-shaped grooves 6a.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

2. Description of the Related Art For example, facial cleansers and creams having relatively high viscosity are generally sold and used in tube containers using flexible tubes. This tube container generally comprises a body portion for containing the contents, a neck portion to which the cap is attached, and a shoulder portion having a conical curved surface between them, and the cap attached to the neck portion is removed. The part is appropriately pressed and the contents are pushed out from the spout through the neck and used.

[0002] In such a tube container, the shoulder and the neck are screw-type or snap-type caps for tightly sealing the contents, even if the body is made of a soft material to push out the contents. In order to provide structural strength, a thicker wall or a relatively hard material is used. For this reason, the shoulder and the neck are less likely to deform than the trunk, making it difficult to completely use the stored contents, and there is a problem that a considerable amount of contents remains when the tube container is discarded. is there.

Therefore, many techniques have been proposed for the purpose of reducing the residual amount. For example,
Examples of tube containers that allow the contents to be taken out to the end include Japanese Utility Model Laid-Open No. 06-059240 and Japanese Patent Laid-Open No. 10-264947. The invention disclosed in the former Japanese Utility Model No. 06-059240 has grooves of various shapes arranged on the front side and the back side of the shoulder of the tube container, making the shoulder easy to bend and the content of the contents is reduced. Extrudability is improved. Further, the latter invention disclosed in Japanese Patent Application Laid-Open No. 10-264947 is a combination of two grooves passing from the surface of the shoulder to the periphery of the neck, a groove passing through the middle thereof, and a groove extending radially outward. And
The extrudability of the contents is improved by folding the shoulder portion substantially flat.

[0004]

However, in the above-mentioned conventional tube container, the extrudability of the contents around the shoulder is improved, and it is difficult to extrude the contents at the neck. However, there is a problem that the contents may remain.

Accordingly, an object of the present invention is to provide a tube container capable of reducing the residual amount of the contents of the neck.

[0006]

In order to solve the above-mentioned problems, a typical configuration of a tube container according to the present invention comprises a body for containing contents, a shoulder for closing a tip of the body, A tube container comprising: a tube main body including a neck portion having an opening; and a hinge cap attached to the neck portion of the tube main body and integrally forming a lid main body and an upper lid via a hinge portion. The neck of the main body is formed to have a low height, an L-shaped groove is formed in the periphery of the neck, and the convex portion of the hinge cap is fitted vertically into the L-shaped groove. It is characterized by rotating in the circumferential direction and guiding the convex portion to the L-shaped groove to make an agreement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a tube container according to the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a tube container according to the embodiment, FIG. 2 is a structural diagram of a hinge cap, FIG. 3 is a diagram illustrating an operation of the tube container, and FIG. 4 is a diagram illustrating scraping of contents.

As shown in FIG. 1, a tube container 1 comprises a tube body 2 and a hinge cap 3. The tube body 2 includes a body portion 4 for storing contents such as cosmetics,
A shoulder 5 for closing the tip of the body 4 and a neck 6 fitted with the hinge cap 3 are provided.

The body 4 has a flexible tubular body having a thermoplastic resin layer, one end of which is folded and thermally bonded, and the other end of which is closed by a circular shoulder 5 to accommodate the contents. are doing. Shoulder 5
A central portion 6 is made up of a neck portion 6 made of relatively hard plastic.

Although the joint surface between the shoulder portion 5 and the body portion 4 is formed in a circular shape, the joint surface is not limited to a circular shape, but may be formed in, for example, an elliptical shape.

The neck 6 has an opening 7 at its tip for discharging contents, and an L-shaped groove 6a on the outer periphery.
The opening 7 is formed in a wide-mouthed circular shape. L-shaped groove 6
a is formed in the height direction from the tip of the neck portion 6 to the center, and is formed in the circumferential direction from the center, and the tip of the neck portion 6 of the L-shaped groove 6 a It is formed in a C shape.

The hinge cap 3 includes a lid body 8, an upper lid 9,
The lid body 8 and the upper lid 9 are hinged with each other.
Are formed integrally so as to be openable and closable.

As shown in FIG. 2, the lid body 8 includes
It consists of an annular groove 12, a spout 13, a projection 11, and a tube container 1.
Is fitted to the tube container 1 so that the neck 6 of the tube container 1 is fitted into the annular groove 12. Here, after the convex portion 11 is vertically fitted into the L-shaped groove 6a, the hinge cap 3 is rotated in the circumferential direction to guide and fit the convex portion 11 into the L-shaped groove 6a. The hinge cap 3 does not come off from the hinge cap 3 even if it is pulled, and the projection 6b provided at the end of the L-shaped groove 6a prevents the projection 11 from returning. Prevents coming off.

The spout 13 is provided at the center of the top surface of the lid body 8 and is tapered so that the diameter of the upper part is larger than the diameter of the lower part so that an inner plug 14 described later can be easily fitted.

The upper lid 9 comprises a hinge part 10, an inner plug 14, and a knob 15. A hinge portion 10 and a knob 15 are formed on the side surface of the upper lid 9 so as to face each other. An inner plug 14 is provided on the lower surface of the upper lid 9 so as to hang down from the center of the lower surface. The outlet 13 was configured to be sealed. By pushing up the knob 15, the locking portion 13a of the spout 13 and the locking portion 14a of the inner plug 14 are formed.
Is released and the upper lid 9 is opened centering on the hinge portion 10.

Next, the operation of the tube container will be described. As shown in FIG. 3, in order to pour out the contents of the tube main body 2, the body of the tube main body 2 is pressed to push out the contents from the spout 13. Then, the contents stored in the tube body 2 are consumed, the remaining amount is reduced, and the contents are discharged from the spout 13.
When it is no longer possible to push out from the tube body, the hinge cap 3 is rotated to remove the fitting between the pulling projection 11 and the L-shaped groove 6a, and remove it from the tube body 2. Then, as shown in FIG. 4, a finger is inserted from the opening 7 to form the shoulder 5 and the neck 6.
The contents remaining in the vicinity of are scraped and used. This makes it possible to reduce the residual amount in the tube main body 2 at the end of use.

As described above, since the opening 7 of the neck 6 is formed wide and the hinge cap 3 is attached to the L-shaped groove 6a of the neck 6, the neck 6 can be formed low. Easy to insert finger, shoulder 5 and neck 6
Can easily be taken out of the contents remaining in the vicinity of.

[0018]

As described above, the neck portion can be formed low by forming the opening portion of the neck portion wide and attaching the cap to the L-shaped groove of the neck portion. A tube container which is easy to stab and has excellent removability of contents remaining around the neck can be obtained.
