Description

Tube container {TUBE-TYPE PACKAGE VESSELS}

The present invention relates to a tubular packaging container, and more particularly, to a tubular packaging container for pressurizing or squeezing out contents which can not be smoothly discharged in a container, such as liquid or gel cosmetics having high viscosity, cosmetic cream, Lt; / RTI >

In general, cosmetic containers containing liquid or gel-like contents having high viscosity such as cream or gel are formed of flexible tube, hard plastic or glass, and particularly, in the case of the tube container, .

However, when the contents of the conventional tube container are contained in a predetermined amount or more due to the physical nature of the contents being pushed out through the outlet due to the action of pressing, the contents can be discharged relatively easily by simply pressing the body lightly. However, It is not difficult to squeeze the contents, and there is a limit to the use of the contents, in which a part of the contents remains in the part of the outlet (shoulder) even if the body is strongly squeezed.

That is, as shown in FIG. 1, the tubular container 1 is formed of soft synthetic resin so that the lid 3 can be hermetically closed without stably maintaining the shape and inflow of air, as shown in FIG. 1, Since the shoulder 2 is formed of a hard synthetic resin, when the contents are squeezed, the portion of the shoulder 2 is not flatly deformed to form a space at the boundary between the body 1 and the shoulder 2, The contents are left in the space, and thus the economic loss is caused.

Accordingly, Korean Patent Laid-Open Publication No. 2001-0088034 proposes a tube container having a structure in which no residue is present in the container. However, since the extrusion member for discharging the contents is embedded in the body, There is a problem that it is very inconvenient to use since the extrusion member must be pushed up when the contents are discharged.

A so-called pump container in which the contents are discharged by a predetermined amount by a pumping operation in which the nozzle is pushed is proposed. However, since the contents are unintentionally leaked through the discharge port due to the discharge and vacuum pressure remaining in the container, And since the nozzle portion is always open, the contents may easily be dried to cause clogging or contamination of the nozzle. Further, the structure of the pump is too complicated, and the production cost is considerably higher than that of the tubular container.

A plurality of first engaging projections 36 are formed on the outer circumferential surface of the lower portion of the shoulder 30 at a predetermined interval in order to reinforce the engaging force of the shoulder 30 in surface contact with the cap 40 when the cap 40 is engaged.

Here, the width of the shoulder 30 is gradually narrowed toward the upper discharge hole 35, so that the discharge amount of the contents can be controlled more stably.

The cap 40 can be coupled in an invisible manner while elastically covering the upper portion of the shoulder 30 and at the same time can be coupled with a jar or cup having an upper part opened with a hard synthetic resin And a thread 41 having a shape corresponding to the thread 31 of the shoulder is formed on the lower outer circumferential surface of the shoulder 30 so that the shoulder 30 can be engaged with the shoulder 30.

A stopper 49 is formed on an inner surface of the cap 40 opposite to the discharge hole 35 of the shoulder to prevent the contents from leaking out by blocking the discharge hole 35 when the tube container is packaged have.

In addition, in the lower inner circumferential edge of the cap 40 corresponding to the first engaging projection 36 of the shoulder, when the cap 40 is engaged with the shoulder 30, contact interference is resiliently deformed with the first engaging projection 36 And a collar 45 is integrally formed to prevent the engagement state of the cap 40 from being released easily or the cap 40 to be freely detached from the shoulder 30.

As shown in FIG. 5, when the shoulder 30 and the cap 40 are deformed into a small container, the tubular container according to the first embodiment of the present invention can be selectively used by the user And a stopper 50 for preventing the contents from leaking can be further provided.

A plug groove 48 may be formed for plugging the lower portion of the cap 50 inward from the upper surface of the cap 40 so as to stably store the cap 50 when used as a tube container.

In the tube container according to the first embodiment of the present invention, the contents are injected into the opening of the tube body 10 through the coupler 20 in a state of being thermally fused or thermally compressed, and then the shoulder 30 and the cap 40) are screwed and tightened in order to keep the contents sealed and packaged.

Thereafter, when the contents contained in the tube body 10 are almost exhausted by use or the like, the cap 40 and the coupler 20 are disengaged from the shoulder 30, The contents of the tube body 10 are turned over and the contents of the tube body 10 are transferred to the cap 40 through the openings and then the opening of the cap 40 and the lower portion of the shoulder 30 are screwed together, The contents contained in the cap 40 can be quickly and easily removed from the body 40 by a simple operation of releasing the shoulder 30 without opening the tube body 10 It can be discharged and consumed.

At this time, the discharge hole 35 of the shoulder may be sealed by plugging the stopper 50 to minimize the amount of air contacted by the contents, thereby delaying or preventing deterioration of the contents.

Therefore, it is not necessary to strongly tighten the tube body 10 in order to squeeze the remaining contents in a small amount as in the prior art, and it is possible to prevent loss and waste by completely consuming the remaining amount of the contents, It is possible to minimize the volume of the container which is unnecessarily occupied, thereby improving space efficiency and convenience in carrying and storing.

That is, the present invention can improve the convenience and activity of carrying and storing by combining and juxtaposing the tubular container and the hard container integrally, and can simultaneously use and extinguish both functions of two products with one article It is possible to maximize the functionality and usability, and to improve the economical efficiency of the use, thereby promoting the convenience of use.

The cap 40 covers the upper portion of the shoulder 30 and can be elastically coupled to the coupler 20 in an interference fit manner. The cap 40 is formed of a hard synthetic resin so as to be able to store contents therein, 30 are formed on the lower inner circumferential surface so as to be threadably engageable with the threads 32 of the shoulders.

A plurality of second engaging projections 46 are formed on the outer circumferential surface of the lower portion of the cap 40 at predetermined intervals in order to strengthen the engaging force of the coupler 20 in surface contact with the coupler 20.

That is, when the opening of the cap 40 is brought into contact with the engaging jaw 25 of the coupler 20, the second engaging projection 46 can be elastically deformed to maintain a more firmly engaged state, At the same time, in the state of mutual coupling, contact interference with the locking jaw 25 is caused to easily release the coupling state or prevent the cap 40 from being freely detached from the coupler 20.

A stopper 49 is integrally formed on the inner side surface of the cap 40 opposite to the discharge hole 35 of the shoulder to prevent the contents from leaking when the tube container is packed together with the discharge hole 35 have.

8 and 9, when the shoulder 30 and the cap 40 are transformed into a small container, the user can selectively place the shoulder 30 and the cap 40 in the discharge hole < RTI ID = 0.0 > (50) for closing the cover (35) and serving as a lid for preventing leakage of contents.

A plug groove 48 may be formed for plugging the lower portion of the cap 50 inward from the upper surface of the cap 40 so as to stably store the cap 50 when used as a tube container.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments or constructions.
