Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a spout opening device for a perfume bottle or the like having a tubular glass spout.

BACKGROUND OF THE INVENTION In order to prevent the contents from evaporating, perfume bottles have a neck with a spout formed into a narrow neck, into which the body continues, and are always provided with a stopper-like closure. Also,
Conventionally, the closure part has been a stopper whose narrow part extends to the point where it transitions into the bottle body.

Problems that the invention seeks to solveThe disadvantages of conventional closures include that the relatively small and narrow neck of the bottle spout makes it difficult to open, especially despite the presence of notches usually installed as gripping aids. Women often lament breaking their fingernails when opening this type of lid.

It is an object of the present invention to provide a bottle spout closure device which allows this type of vial to be opened and used easily, while at the same time retaining the advantages of conventional easy closure.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention includes a cap that is attached to the spout of a bottle, and a cylindrical body that extends vertically through the cap. Provide a pouring device,
A bulge is formed at the lower end of the cylindrical body along the inner periphery of the bottle body inside the spout of the bottle, and a closing cap is detachably provided above the cap of the cylindrical body to cover the bulge. using means.

Operation The device of the invention consists of two parts: a pouring device consisting of a cap and a cylindrical body, and a closing cap. When the pouring device is attached to the spout of the bottle, the bulge at the end of the cylindrical body runs along the inner periphery of the bottle body, and this bulge fixes the pouring device, and the cap tightly fits onto the spout of the bottle. Because it is crowned with water, it acts to prevent perfumes from evaporating. Further, the closing cap can detachably close the cylindrical body, and prevents wasteful evaporation of perfume from the upper end of the cylindrical body when perfume is not used.

Therefore, the seal of the bottle is the cap and the spout of the bottle.

It can be completely carried out in two places: the cylindrical body and the closing cap.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, the object according to the invention consists of two parts: a closure cap 1 and a dispensing device with a cap 2 and a tube 3. In FIG.

This is to avoid forming threads in the neck area of the bottle itself. Such threads are labor intensive and would lead to increased manufacturing costs.

The cylindrical body 3 extends vertically through the cap 2, and the cap 2 is located in a certain area as shown below. The cylindrical body 3 extends inside the spout of the bottle to the point where the narrow part of the bottle neck transitions to the bottle body and widens, and has a bulge 4 at its end. Preferably, it has a circular bulge. This thickness can of course be interrupted and thus formed in several sections.

It is important that the dispensing device is firmly fixed in the perfume bottle by tightly fitting the bulging portion 4 into the bottle body and the narrow portion transitioning into the bottle body. This is preferably facilitated by the fact that the tube 3 passes through the cap 2, the cap 2 being in a position corresponding to the distance from the upper cap edge to the closing cap and firmly resting on the perfume bottle. The cap edge must be located away from the lower end of the tube 3 and its position is chosen so that a secure seating of the device in the perfume bottle is thus guaranteed.

After the fabrication of this part of the object according to the invention, it was determined that the dripping properties of the tubular glass of the perfume bottle were not optimal.

However, this drawback can be overcome by forming a capillary groove 5 cut along the inner wall of the cylindrical body 3 from near the upper end of the cap 2 to the upper end of the cylindrical body 3, as shown in FIG. It became clear that it could be done. This groove 5
is approximately in the shape of a vertically cut small tube that expands toward the upper end of the cylindrical body 3 in the shape of a trumpet.

Now, in order to cover the cylindrical body 3 with the closure cap 1 and reliably close the spout of the bottle, the closure cap 1 must be
must be attached to the pouring device so as to cover the upper part of the cylindrical body 3 than the cap 2, but this closing cap l
Various possibilities can be selected for attaching the dispenser to the dispensing device.

First, as shown in Fig. 2, on the outer wall of the cylindrical body 3.

Attach a thread 6 at the height of the cap 2 or at an arbitrary point above the cap so that it corresponds to the thread provided inside the closing cap l, screw them together, and attach the cylindrical body 3.
may be closed. Incidentally, instead of a thread, a ring-shaped convex part may be formed and fixed by fitting into a pair of concave parts formed at corresponding locations on the closing cap l. The convex portion is not ring-shaped and may be interrupted at several points.

In addition, as shown in FIG. 3, a plug 7 corresponding to the diameter of the cylindrical body 3 is protruded from the closing portion side of the closing cap 1, and when the cylindrical body 3 is closed by the closing cap 1, this plug 7 can be inserted at least inside the cylindrical body 3,
Since the cylindrical body 3 itself can be closed, evaporation of perfume and the like can be prevented as much as possible. Here, the length of the stopper 7 is not limited by other factors; if the embodiment shown here and the threaded connection shown in FIG. 2 are used together, the sealing performance will be even higher. Become.

In order to securely close the cylindrical body 3 by covering it with the closing cap l, it is further proposed that, as shown in FIG. 8, the length of which may be arbitrary; however, this protrusion 8, if threaded, must in any case terminate in the thread of the tubular body 3. Otherwise, it ends at the height of cap 2. By providing concave portions 9 corresponding to the convex portions 8 at two opposing locations on the inner wall of the closing cap l, the cylindrical body 3 can be closed by the closing cap l by fitting both.

Another embodiment of covering the cylindrical body 3 with the closing cap 1 is not limited to this, but as shown in FIG. An L-shaped recess lO is provided in which two protrusions l are formed projecting on the inside of the closure cap l! mated,
It may lock.

Still another embodiment of covering the cylindrical body 3 with the closing cap 1 is proposed, as shown in FIG. At a defined lateral distance, the closure cap 1 is provided with a preferably circumferential recess 12 with a pin 13 on its open side.
Alternatively, it may include a rotating ring, whereby the pin 13 is fitted into the rotating recess 12 and locked.

Although each of the above embodiments has been described with reference to perfume bottles, the bottle is not limited to this, and can also be applied to bottles containing other highly volatile liquids, regardless of the purpose. do not have.

Effects of the Invention The present invention provides a pouring device having a cap and a cylindrical body? :,I
1 and a closing cap that covers the cylindrical body, the cylindrical body extends vertically through the cap, and forms a bulge at the lower end so that it is attached to a perfume bottle, etc., so that it can be used as a pouring device. The bulge is attached to the bottle, and the cap seals the spout of the bottle. Therefore, unnecessary evaporation of perfume and the like can be prevented. Further, since the cylindrical body is closed with a closure cap, it can be completely sealed when not in use, and when in use, it is easy to handle because the closure cap is simply removed.

Furthermore, since the device of the present invention is simply attached to the spout of the bottle, it is easier to construct than the bottle itself, which is modified as a closing device.

It is also highly economical.
