Description

  The present invention relates to a liquid discharge container, and more particularly, to a liquid discharge container including a simple cover that can prevent a pump mounting cap from being loosened or dropped during transportation or display at a store.

  A liquid discharge container that covers the head of the discharge pump attached to the mouth tube of the container to prevent the pump mounting cap from falling off during transportation or display at the storefront, and to prevent opening by fraud Is conventionally known as described in Patent Documents 1 to 3.

  However, since the cover member described in Patent Literature 1 and Patent Literature 2 has a shape that covers the entire head of the discharge pump attached to the mouth tube portion of the container, it becomes larger than necessary. Not only did it take up space, it required many materials and increased manufacturing costs.

Further, the cover member described in Patent Document 3 is improved as compared with those of Patent Document 1 and Patent Document 2 as partially covering the head of the discharge pump.
However, since the two points passing through the center line of the pump mounting cap have been opened, there is a possibility that the pump mounting cap may be opened by being gripped and rotated by the fingers using these two points as the force points.

The inner peripheral surface is screwed with a screw that is screwed into the mouth tube portion, and the lower end of the cap cover portion of the simple cover is below the neck ring of the container mouth tube portion. A configuration characterized in that a locking ring to be engaged is formed.

  In order to save material, the nozzle cover portion has a narrow rectangular shape whose width does not exceed the diameter of the nozzle head.

Since the range exceeding at least 180 ° of the circumference of the pump mounting cap is covered with the simple cover, the pump mounting cap cannot be easily rotated, and inadvertent opening can be prevented beforehand.
In addition, since only the essential part of the head of the discharge pump is selected and covered, the cover can be simplified and the material can be saved.
The cover can be easily removed when in use

Next, the liquid discharge container of the present invention will be described with reference to the drawings.
1 and 2, A is a container, B is a pump mounting cap, C is a discharge pump, and D is a simple cover.
The container A can store household products such as shampoos, rinses, body soaps, cosmetics, detergents, and laundry finishes as content liquids.

The container A is a container blow-molded with a synthetic resin, and includes a mouth tube portion 1 and a body portion 2, and a screw (not shown) and a neck ring 3 are formed on the outer periphery of the mouth tube portion 1. ing.
The neck ring 3 has a shape in which the lower side is bent at a substantially right angle, and has a shape corresponding to a locking ring of a simple cover D described later.

  A knurling 4 for preventing slippage is screwed on the outer peripheral surface of the pump mounting cap B, and a screw (not shown) that is screwed with a screw on the outer periphery of the mouth tube portion 1 of the container A on the inner peripheral surface. Is screwed.

The discharge pump C is attached to the mouth tube portion 1 of the container A via a pump mounting cap B, and a nozzle head 6 provided with a discharge nozzle 5 is attached to the upper portion thereof, and the inside thereof A conventionally known pump mechanism is built in.
Then, by moving the nozzle head 6 up and down, the content liquid is sucked from the container A and discharged from the discharge nozzle 5.

  As shown in FIGS. 1 to 3, the simple cover D is made of synthetic resin and has a cap cover portion 7 having a shape surrounding the knurl 4 engraved on the outer periphery of the pump mounting cap B, and the cap. A rectangular nozzle cover portion 8 is provided continuously to the cover portion 7 and covers the central portion of the upper surface of the nozzle head 6.

  The shape of the cap cover portion 7 is an arc shape that partially surrounds the entire circumference of the knurl 4 formed on the outer periphery of the pump mounting cap B, and as shown in FIGS. In other words, a part beyond the center line is surrounded by a circle exceeding at least 180 °, and a part thereof is open.

  The reason why the part is opened is that the simple cover D can be easily removed during use.

  A locking ring 9 projecting inward is provided at the lower end of the cap cover part 7, and the leading edge of the locking ring 9 is substantially in contact with the outer periphery of the container mouth tube part 1 and the neck ring of the container A. 3 is suitable for being fitted.

  The nozzle cover portion 8 has a rectangular shape as a whole, and its width is larger than that of the discharge nozzle 5 of the discharge pump C and does not exceed the diameter of the nozzle head 6. Only a part of the nozzle 5 is covered, and a portion that protrudes more than necessary is not formed.

As shown in FIG. 3, the nozzle cover portion 8 is provided with two bent portions 10 so as to surround the upper portion of the nozzle head 6.
The bent portion 10 has a thin shape and is easily bent. However, the bent portion 10 may be from the inside or from the outside.
A fitting insertion hole 11 for holding the discharge nozzle 5 is drilled at the tip of the nozzle cover portion 8.

  In the embodiment, the two bent portions 10 are provided. However, as one portion on the tip end side, it may be merely curved so as to be in contact with the nozzle head 6 on the other side.

Next, usage conditions and operational effects of the discharge container of the present invention will be described.
After filling the container A with the content liquid, the discharge pump C is attached, and the simple cover D is further attached.
In attaching the simple cover D, first, the fitting nozzle 11 of the tip of the nozzle cover portion 8 is inserted into the discharge nozzle 5 of the discharge pump C, the nozzle cover portion 8 is bent by the bent portion 10, and then the cap cover portion. 7 partially surrounds the knurl 4 on the outer periphery of the pump mounting cap B, and at the same time, the locking ring 9 is fitted to the lower side of the neck ring 3 of the container A.

  In that case, when the cap cover part 7 is pushed into the outer periphery of the pump mounting cap B, the cap cover part 7 is elastically deformed. can do.

  Therefore, the simple cover D has the nozzle head 6 and the pump mounting cap B when the fitting insertion hole 11 of the nozzle cover portion 8 is engaged with the discharge nozzle 5 and the locking ring 8 of the cap cover portion 7 is engaged with the neck ring 3. It is firmly attached to the.

  When the pump mounting cap B is gripped and rotated, the two opposing points of the knurl 4 on the outer periphery of the pump mounting cap B can be rotated by the moment of the couple due to the frictional force.

  In the present invention, since the cap cover portion 7 surrounds the portion beyond the center line of the knurl 4, the point of application cannot be two points passing through the center line of the knurl 4. Further, when the upper part of the cap cover part 7 is gripped, the cap cover part 7 is deformed and touches the knurl 4, but the frictional force is not large as compared with the case of directly gripping with the hand.

Therefore, in the case of the present invention, the knurling 4 cannot be gripped with a large frictional force, and a moment of a large couple cannot be generated, so the pump mounting cap B cannot be effectively rotated, Inadvertent opening can be prevented beforehand.
Further, if the range surrounding the center line is enlarged, the two opposing points cannot be gripped, and it becomes extremely difficult to rotate the pump mounting cap B.

  Further, not only does the pump mounting cap B not be easily rotated, but also the discharge pump C is covered by the simple cover D, so that it is as if an unauthorized opening prevention function is provided. It seems that it is possible to prevent opening by fraud.

  Furthermore, a tack label or the like is pasted between the upper end of the cap cover portion 7 of the simple cover D and the nozzle head 6 or between the side end portion of the cap cover portion 7 and the knurled 4 of the mounting cap B. It is effective for preventing fraud, and the presence or absence of fraud can be immediately confirmed by looking at the state of the tack label.

  Since the cap cover portion 7 of the present invention has a shape that is partially opened, the simple cover D can be easily removed by elastically deforming in use, and it is excellent in terms of handling. It has become.

  In order to prevent the pump mounting cap from being easily rotated, the purpose can be achieved by surrounding the pump mounting cap with a cover having a relatively simple structure, and the pump mounting cap can be loosened during transportation or store display. Dropout can be prevented.
