Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tube with a closure membrane that prevents an erroneous operation, and more specifically, relates to a tube with a closure membrane that prevents an erroneous operation that can perforate the closure membrane only by a rotation operation of a one-touch cap.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, some tube containers for storing pharmaceuticals, cosmetics, food products, and the like are provided with a closed membrane at the mouth portion to protect the contents during the distribution process. When taking out the contents from the tube with the closure membrane that prevents such an erroneous operation, the tip of the needle body provided on the side opposite to the female threaded portion of the cap is pierced into the closure membrane to break the closure membrane and remove the contents. It was extracted.
[0003]
Examples of the conventional tube with a closure membrane that prevents such erroneous operation are shown in FIGS. In the figure, reference numeral 50 denotes a tube container main body, and a closing film 52 is formed at the mouth 51 of the tube container main body 50. A recess 55 is formed on the opposite side of the cap 51 that is screwed into the mouth 51 via the top surface 54, and a needle body 56 is formed at the center of the recess 55. By piercing and breaking the closing membrane 52 with the needle body 56, the mouth portion 51 of the tube container main body 50 is perforated, and the contents can be extracted.
[0004]
[Problems to be solved by the invention]
However, such an invention has the following drawbacks.
(1) The closing membrane 52 is perforated due to careless operation.
(2) Once the cap 53 has been removed from the mouth 51, the cap 53 must be turned upside down and the tip of the needle body 56 directed downward so that the closure membrane 52 must be broken. In addition, there is an inconvenience that must be made, and a cap screwing operation and a detaching operation are necessary even after the closure membrane is perforated.
(3) Since the contents adhere to the needle body 56 when the closure film 52 is torn, there is a drawback that when the cap is tightened again with the contents attached, the needle body 56 faces upward and impairs the aesthetics. .
(4) Conventionally, it is not possible to judge from the appearance of the cap and the tube with the closure membrane whether or not the closure membrane has been perforated when the cap is pierced with the needle of the cap and then the cap is attached again. It was possible.
[0005]
The present invention has been made by paying attention to such a conventional problem, and can prevent perforation due to an erroneous operation, the perforation operation of the closing membrane is easy, and the aesthetics of the cap is good. An object of the present invention is to provide a tube with a closure membrane that does not require a screwing operation and a detaching operation of a cap and prevents an erroneous operation.

[0007]
Embodiment
1 to 6 are cross-sectional views showing a first embodiment according to the present invention. The tube container body 1 and the closing membrane 2 are made of a metal material such as aluminum or a synthetic resin material such as polyethylene, and the one-touch cap 3 is made of a synthetic resin such as polyethylene. The one-touch cap 3 includes an upper lid body 3a and a lower lid body base portion 3b, and is connected to the hinge portion 8 so as to be opened and closed. The cylinder 5 formed inside the lid base 3b is formed with a female screw, and the male screw of the inner plug 9 fitted in the mouth 4 of the tube container body 1 is screwed into the female screw. ing. Further, a needle body 6 is formed on the top surface of the cylindrical body 5 so that the tip of the cylinder body 5 faces the closing membrane 2. A plurality of holes 6 a are formed in the side surface of the needle body 6. A plurality of blade pieces 7 (eight in the first embodiment, see FIG. 6) partitioned at regular intervals by slits (not shown) at the lower end of the internal thread of the cylindrical body 5. Is formed. The blade piece 7 is formed in order to prevent the closing membrane 2 from being perforated by the needle body 6 due to an error when the one-touch cap 3 descends along the screw. That is, it functions as a spacer. In addition, the blade piece 7 may be partially formed instead of the entire circumference of the cylindrical body 5. Further, a lid engaging piece 3d is formed at the inner center of the one-touch cap 3, and this lid engaging piece 3d is the mouth 3c of the one-touch cap 3 formed above the needle body 6 of the lid base 3b. And engages freely.
[0008]
Next, FIG. 7 shows a second embodiment. The feature of the second embodiment is that the tube main body 11 is attached to the female screw of the cylindrical body 15 formed on the lid base portion 13b of the one-touch cap 13. It is in the point where it is screwed directly. That is, as in the first embodiment, the cylindrical body of the lid base portion of the one-touch cap is not screwed into the inner plug body, but the female screw of the cylindrical body 15 of the one-touch cap 13 and the tube container body 11. The male screw of the mouth portion 14 is directly screwed. Other configurations are the same as those of the first embodiment.
[0009]
Next, the operation of the present invention will be described. First, when perforating the closure membranes 2 and 12 to perforate the mouth portions 4 and 14, the one-touch caps 3 and 13 are rotated along the male threads of the mouth portions 4 and 14 of the tube container bodies 1 and 11. Then, the cylinders 5 and 15 are lowered while being screwed together. Since the needle bodies 6 and 16 are similarly lowered while rotating, the mouth portions 4 and 14 are opened as shown in FIG. Simultaneously with the drilling, the plurality of blade pieces 7 and 17 formed at the lower ends of the female screws of the cylinders 5 and 15 are pressed by the cylinders 5 and 15 as shown in FIG. 7 and 17, respectively, along the tapered shoulder portion 9a of the inner plug body 9 in the first embodiment, and along the tapered shoulder portion 11a of the tube container body 11 in the second embodiment. It is gradually bent outward in the radial direction. The blade pieces 7 and 17 are not bent by a weak pressing force due to an error, but are bent by a strong pressing force, and thus have a function as a spacer for preventing the closing films 2 and 12 from being perforated by an error.
[0010]
Further, when the closing membranes 2 and 12 are pierced by the needle bodies 6 and 16, the one-touch caps 3 and 13 are screwed under the mouth portions of the inner plug body 9 or the tube container body 11, so that the closing membrane 2 , 12 can be confirmed to be perforated by the needle bodies 6,16. Compared to the case where the closing membranes 2 and 12 are not perforated, the one-touch caps 3 and 13 are screwed down to the lower side of the male screw, so that the closing membranes 2 and 12 of the tube container bodies 1 and 11 are perforated. Can be easily recognized in appearance. A difference of 5 mm to 8 mm was easily visually observed before and after drilling.
Further, before the closing membranes 2 and 12 are perforated from the gap between the one-touch caps 3 and 13 and the tube container main bodies 1 and 11, the blade pieces 7 and 17 are in a state of standing on the shoulder 9a of the inner plug body 9. Although it is in contact, after being perforated, the blade pieces 7 and 17 are in contact with the shoulder 9a of the inner plug 9 in a state of spreading outward in the radial direction. it can. Then, as shown in FIG. 4, by opening the lids 3a and 13a and pressing the tube container main bodies 1 and 11, the contents pass through the mouths 4 and 14 and the holes 6a of the needles 6 and 16, 16a is extracted outside. Once perforated, the contents can be easily extracted by simply opening and closing the lids 3a, 13a of the one-touch caps 3, 13 with one hand.
[0011]
【The invention's effect】
As described above, according to the present invention, there is an effect that perforation due to an erroneous operation can be prevented and the perforation operation of the closing membrane is easy. In addition to being excellent in terms of the aesthetics of the cap, it can be easily recognized on the appearance whether or not the closure membrane has been perforated, and once perforated, there is no troublesome operation of unscrewing the cap, and the lid can be used with one hand. It is possible to easily extract contents by simply opening and closing.
