Description

[Detailed description of the invention] The present invention relates to a container, and more specifically to a relatively flexible container made of synthetic resin, etc., such as a tube container for cosmetics, etc., which can hold the contents. This relates to a type of container that is used by extrusion.

Conventionally, this type of container has required a cap to close the spout hole through which the contents are extruded.

This cap is generally attached by screwing to the neck part formed at one end of the container, the tip of which is a pouring hole, and the cap is unscrewed when in use, and then screwed back on again after use. Operations such as doing this were required.

Therefore, it is not a hassle when you are busy,
If you do, you may forget to tighten the cap, so
This is particularly inconvenient for items that are frequently used in daily life.

Furthermore, providing a cap increases the number of parts and increases the number of manufacturing steps, so the impact this has on the cost of the container is not insignificant.

However, on the other hand, if the spout hole is open even when not in use, not only can it cause leakage, but also outside air can enter the container through the spout hole and cause spoilage and deterioration of the contents such as cosmetics. Therefore, it is necessary to close the spout hole to maintain airtightness when not in use.

The present invention was developed mainly in view of the above-mentioned circumstances, and its purpose is to simplify the operation during use and reduce manufacturing costs by eliminating the need for a cap, and to reduce the production cost when not in use. The purpose of the present invention is to provide a completely new capless container that maintains airtightness and prevents contents such as cosmetics from leaking, rotting, or deteriorating.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, a preferred embodiment of the present invention applied to a tube container for cosmetics will be described in detail with reference to the drawings.

Reference numeral 1 denotes a body of a flexible tube made of synthetic resin, and a ceiling wall 2 is integrally welded at its peripheral edge 3 to the tip of the body.

This ceiling wall 2 is made of flexible resin like the body part 1, preferably made of the same resin as the body part, and its shape is gently curved outward. desirable.

Reference numeral 4 denotes a spout hole provided in the central part of the ceiling wall, into which the upper part of the generally truncated conical protrusion 6 of the stopper 5 is fitted from below. The spout hole is closed.

On the other hand, the plug body 5 is fixedly held in a channel chamber 7, and in this embodiment, the channel chamber extends downward from the ceiling wall approximately vertically with the spout hole 4 of the ceiling wall 2 as the center. It is formed by an annular wall 8.

A protrusion 9 is provided on the inner surface of the lower end of the annular wall 8, and a rib 10 is provided on the inner surface of the upper portion of the annular wall. Peripheral part 1 of 5
1 is clamped, and the stopper is thus fixedly held in the channel chamber 7.

Next, the stopper 5 has an arbitrary number of outlet ports 1 around the protrusion 6.
2 is bored, and the flow path chamber 7 and the inside of the body 1 can communicate with each other through the outlet.

Reference numeral 13 denotes a ring-shaped valve seat made of synthetic resin that is fitted above the outlet 12 and is formed to be larger than the diameter of the outlet, and in the lower position shown in FIG. 12 is inserted so as to close it off.

In addition, 14 is a sealing member affixed to the outer surface of the ceiling wall 2, and its edge 15 is not affixed to the ceiling wall 2 and body 1 so as to serve as a knob when peeling.

An adhesive may be used to attach the sealing member, or a tape with an adhesive surface provided in advance may be used as the sealing member, but it is more preferable to use the synthetic resin bonding method related to the applicant's previous application. That is, after punching and inserting the tubular sleeve that will become the body 1 into a predetermined shape and inserting the sealing member 14 into an injection mold, the body 1 and the ceiling wall 2 are injected and filled with molten resin. At the same time, the sealing member 14 is attached to the ceiling wall 2, while the body part 1
The ceiling wall 2 and the ceiling wall 2 are completely welded together at the peripheral edge 3.

At this time, the upper end of the body 1 is curved to cover the peripheral edge 3 of the ceiling wall 2, thereby preventing the edge 15 of the sealing member from sticking.

Further, the bottom portion 16 may be provided with a hole for hanging (not shown), so that it can be used as a hanging container when on display or when not in use.

To use the container configured as described above, first peel off the sheet member 14 attached to the ceiling wall 2 by pinching the edge 15 with your fingers.

This sheet member 14 is used to prevent leakage when external pressure is applied to the container during transportation or display at a store, and is therefore no longer needed once it is peeled off.

When the rear body part 1 from which the sheet member has been peeled is pressed by hand, the pressure increases inside the flexible container containing the cosmetic 17 such as cream, and the cosmetic 17 flows from the outlet 12 of the stopper 5 into the channel chamber. Trying to flow into 7.

At this time, the valve seat 13 fitted above the outlet is pushed upward by the cosmetic, so the outlet opens and the cosmetic 17 flows into the channel chamber 7.

The flowing cosmetic further pushes the valve seat 13 up to the inner surface of the ceiling wall 2 and applies pressure to the ceiling wall, so that as shown in FIG.
bulge outward.

As a result, the spout hole 4 provided in the ceiling wall also moves upward (outward), so that the protrusion 6 of the stopper 5 fixed to the channel chamber 7 separates from the spout hole. In this way, the spouting hole is unblocked and the cosmetic 17 is poured out to the outside.

The pouring of the cosmetic 17 continues while the body 1 is pressed, and when the required amount is taken out and the hand is released to stop the pressing, the pressure from the cosmetic 17 applied to the ceiling wall 2 disappears. The ceiling wall is restored to its original shape and at the same time the spout hole 4 is
The truncated conical projection 6 of the stopper 5 fits into the spout, thereby closing the spout hole again.

Furthermore, when the pressing is stopped, a restoring force is applied to the body 1 and the body returns to its original shape, but at this time, negative pressure is generated inside, so the cosmetics 17 remaining in the channel chamber 7 are removed. is outlet 1
2 into the body 1, and then the ring-shaped valve seat 13 descends to the position of the stopper 5 and comes into close contact with the stopper above the outlet 12 due to negative pressure, thereby sealing the outlet. .

This state is shown in FIG. 3, and since the valve seat 13 closes the outlet 12 when a negative pressure is generated inside, even if the outside air flows into the flow path chamber 7 due to the negative pressure, the valve seat 13 blocks the outlet 12. Even if the outside air is inhaled before the body part 4 is completely occluded, this outside air will not be inhaled to the inside of the body part 1.

What is even more important is that the cosmetics 1 accumulated in the flow path chamber 7
7 is sucked into the interior, the valve seat 13 closes the outlet 12, so the internal pressure of the flow path chamber decreases, and the spout hole 4 located in the upper part of the flow path chamber is located at the approximate truncated end of the plug body 5. This means that the conical protrusion 6 is attracted to the conical protrusion 6, and the fit between them becomes strong, so that the state of closing of the spout hole 4 becomes even better.

In this way, in the container of the present invention, communication with the outside is doubly blocked at the pouring hole 4 and the outlet 12, so that the internal airtightness is improved.

Therefore, there is no need to provide a cap at all, and when in use, simply press the body 1 and the pressure will open the outlet 12 and spout hole 4 and pour out the cosmetics to the outside. Moreover, if the pressing is stopped, the spout hole and outlet are closed by the restoring force of the ceiling wall 2 and the body 1, preventing leakage of cosmetics and inhalation of outside air. This eliminates the need for the operation of attaching and detaching the cap, improving operability, and since there is no cap, the manufacturing process is simplified and costs are reduced.

As described above, according to the capless container according to the present invention, a sealing member is removably attached to a ceiling wall in which a spout hole made of flexible synthetic resin is formed, and the spout hole is A stopper, which forms a channel chamber in the lower part thereof, has a protrusion for closing the spout hole from the inside, and has an outlet formed around it, is fixedly held in the channel chamber; A ring-shaped valve seat is movably inserted between the stopper and the ceiling wall above the outlet of the stopper, so that when the container is pressed with your hand, the cosmetics etc. inside will be released. pushes up the valve seat to open the outlet, then bulges the ceiling wall outward to unblock the spout hole and pour out to the outside. The spout hole and the outflow port are respectively closed by the protrusion and the valve seat due to the restoring force, and furthermore, the spout hole is reliably blocked by the protrusion because the internal pressure of the flow path chamber is reduced. Therefore, leakage of contents and intake of outside air can be prevented without providing a cap, improving operability and reducing manufacturing costs.

In addition, when negative pressure is generated inside the container, the valve seat quickly closes the outlet, so the cosmetics etc. that have been poured out will not be sucked into the inside together with the outside air, making it hygienic. It is also preferable from a surface perspective.

Furthermore, by pasting a sealing member on the ceiling wall, leakage of cosmetics etc. can be prevented even if external pressure is applied during transportation or display.

Incidentally, if the protrusion of the plug body is formed into a substantially truncated conical shape and its upper part fits into the spout hole, the protrusion and the spout can be formed when the internal pressure of the flow path chamber decreases. The fitted state of the holes becomes even stronger, and the airtightness can be further improved.

Although various configurations are possible for forming the flow channel chamber, the flow channel chamber may be formed by an annular wall extending downward from the ceiling wall, and the peripheral edge of the plug body may be shaped like an annular wall extending downward from the ceiling wall. If it is sandwiched between an inward protrusion provided around the lower end of the wall and a rib provided around the inside of the upper part of the annular wall, the structure becomes simple and suitable for manufacturing. is good.
