Description

Improved structure of extrusion container cover

The present invention relates to the field of bottle caps for extrusion containers, and more particularly to an improved structure of an extrusion container cap.

As shown in FIG. 1 , a bottle cap 3 of an extrusion container such as an ointment is provided with a piercing member 31 at the front end, and one side of the piercing member 31 is screwed to the bottle mouth of the container. When used for the first time, the bottle cap 3 is unscrewed, and the sealing film of the bottle mouth of the container is pierced through the piercing member 31. By squeezing the container, the contents can be squeezed out of the container for use.

As shown in FIG. 2 , another type of squeeze-type container bottle cap 4 is shown. The bottle cap 4 is composed of a flip-up upper cover 41 and a lower cover 42 screwed on the container. When used for the first time, the bottle cap 4 is unscrewed, the sealing film of the container mouth is torn off, and the bottle cap 4 is screwed on the container mouth. When it is ready to use, the upper cover 41 is flipped up and the container is squeezed to squeeze the contents out of the container for use. After use, the upper cover 41 is flipped over the lower cover 42, and the tube column 411 in the center of the upper cover 41 is squeezed into the outlet 421 of the lower cover 42, and the convex piece of the upper cover 41 is buckled in the snap-fit groove 422 of the lower cover 42 to achieve a tight closure effect.

The usage structure has the following disadvantages:

1. Sometimes the fluidity of the contents is poor, and the user will increase the squeezing force, but this will result in the contents continuing to flow out under the squeezing pressure even though the amount of contents has been taken. Whether it is the bottle cap in Figure 1 or Figure 2, it cannot block the bottle mouth of the container, causing the contents to flow out and be wasted.

2. As shown in FIG. 2 , since the tube column 411 is directly inserted into the outlet 421 , the outlet 421 will inevitably have residual contents, which will be squeezed out by the tube column 411 , causing the upper cover 41 to always have residual contents, which is unhygienic.

How to improve the defects of conventional bottle caps is a problem that relevant industries are actively trying to solve.

The main purpose of the present invention is to provide an improved structure of an extrusion container cap to solve the problem that the conventional bottle cap cannot block the bottle mouth in time, allowing the contents in the container to continuously flow out.

Therefore, the structure of the present invention is connected to the bottle mouth of an extrusion container, and the bottle mouth is sealed with a sealing film before use; the outer edge of the bottle mouth is provided with a connecting end, providing a bottle cap device assembly; wherein:

The bottle cap device is composed of a bottle cap and a sealing cap; a flow hole corresponding to the position of the bottle mouth is arranged in the center of the bottle cap, and the bottle cap is screwed on the connecting end of the bottle mouth; the sealing cap is connected to the bottle cap through a joint piece, a piercing piece for piercing the sealing film is arranged on the top of the sealing cap, and a plug part for blocking the flow hole is arranged on the side of the sealing cap opposite to the piercing piece, and when the plug part is engaged with the flow hole, it fits on the outer side of the flow outlet.

In an embodiment of the present invention, the outflow hole and the plug are fastened together through a latch mechanism.

In an embodiment of the present invention, the sealing cover has a side of the side breaking piece and is further provided with a slot.

In an embodiment of the present invention, a non-slip pattern is provided on the side wall of the bottle cap.

In an embodiment of the present invention, an inner sleeve is provided on one side of the bottle cap that is joined with the bottle mouth, and the inner sleeve can just abut against the connecting end of the bottle mouth.

Through the above description, the effects that can be obtained by the present invention are roughly as follows: the present invention integrates the bottle cap of the commonly used squeeze container, which can not only pierce the sealing film of the container, but also block the outflow port through the plug of the sealing cap after use, so that the contents in the container can be immediately stopped and prevented from overflowing.

In order to enable the review committee to have a further understanding and recognition of the characteristics and features of the present invention, the following preferred embodiments are listed and illustrated with drawings as follows:

Please refer to Figures 3 to 6. The extrusion container cap structure of the present invention is improved, which is connected to the bottle mouth 11 of an extrusion container 10. Before the bottle mouth 11 is not used, the inside of the container is sealed with a sealing film 12 to prevent the contents from flowing out during transportation. At the same time, it serves as an anti-theft mechanism. If consumers see that the sealing film 12 is damaged, it means that it has been opened and they should return or exchange the product to ensure the safety of product use.

As shown in FIG. 6 , the outer edge of the bottle mouth 11 is provided with a connecting end 13 for assembling a bottle cap device 20 .

As shown in FIGS. 3 to 5 , the bottle cap device 20 is composed of a bottle cap 21 and a sealing cover 22. A flow hole 211 corresponding to the position of the bottle mouth 11 is provided at the center of the bottle cap 21. The bottle cap 21 is screwed to the connecting end 13 of the bottle mouth 11. The sealing cover 22 is connected to the bottle cap 21 via a joint member 23. The form of the joint member 23 is not limited to the method disclosed in the drawings. As long as the bottle cap 21 and the sealing cover 22 can be joined and not separated, the present invention can be used.

As shown in FIG. 3 and FIG. 4 , a piercing member 221 for piercing the sealing film 12 is provided at the top of the sealing cover 22. In order to facilitate the piercing member to be inserted into the sealing film 12, a slot 221A is provided on one side of the piercing member 221. In this way, when a user inserts the piercing member 221 into the sealing film 12, it is not only easier but also easier to observe the insertion depth.

As shown in FIG6 , the sealing cap 22 is provided with a plug 222 for plugging the outlet hole 211 on the side opposite to the piercing member 221; in order to prevent the sealing cap 22 from being easily separated from the bottle cap 21, the outlet hole 211 and the plug 222 are connected by a latch mechanism, that is, the outlet hole 211 has a flange, and the plug 222 has a groove corresponding to the flange, so that the two are buckled into one.

As shown in FIG5 and FIG6, in order to lighten the bottle cap device 20, an inner sleeve 24 is provided on the side where the bottle cap 21 is joined to the bottle mouth 11, and the inner sleeve 24 can just abut against the connecting end 13 of the bottle mouth 11. In this way, the bottle cap 21 does not need to be filled with plastic, which can save material costs, reduce the weight of the container, and reduce shipping costs.

The above is an introduction to the various components of the present invention. The following is an introduction to the usage of the present invention.

1. When using for the first time, unscrew and remove the bottle cap device 20, and pierce the piercing member 221 on the sealing cap 22 into the sealing film 12 of the bottle mouth 11 of the container 10, and then screw the bottle cap device 20 onto the bottle mouth 11.

2. After squeezing out the contents of the container 10, cover the bottle cap 21 with the sealing cap 22, and sleeve the outer side of the outlet 211 with the plug 222 to prevent the contents from flowing out.

3. When the force of squeezing the container 10 is too great, the user can directly lift the cover 22 and use the stopper 222 to fit over the outlet 211 to prevent the contents from flowing out of the container 10 and avoid waste.

4. To make it easier to take out and prevent it from falling, the side wall of the bottle cap is provided with multiple anti-slip grooves.

In summary, the structure of this invention has never been seen in any books or periodicals or used publicly, and it truly meets the requirements for invention patent application. We sincerely request the Bureau to examine it and approve the patent as soon as possible. We would be very grateful.
