Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cap with a punch, and particularly relates to a cap with a punch for opening a container provided with a blind lid.
[0002]
[Prior art]
Conventionally, in tube containers filled with adhesives, drugs, cosmetics, etc., a blind lid has been attached to the mouth of the container body to seal the inner solution and screwed into the mouth of the container body. Some caps are provided with a punch for making a hole in the blind lid.
[0003]
For example, in the cap with a punching tool disclosed in Japanese Utility Model Publication No. 58-21396 shown in FIG. 11, the blind lid 3 made of aluminum or the like provided on the ceiling of the tube container 2 is drilled in the center of the upper surface of the cap 1. A triangular pyramid-shaped shaft portion 4 is integrally provided as a piercing tool, and the screw portion of the cap 1 is further screwed toward the tube container 2 at the start of use, thereby allowing the blind lid 3 to discharge the inner solution. An opening is formed.
[0004]
On the other hand, in addition to the above publication, in other caps with a punch, a straight or L-shaped through passage is provided in the shaft portion 4 so that the inner solution can be discharged to the outside with the cap 1 attached. Some are formed in advance (see, for example, Japanese Utility Model Publication No. 58-37814). In this kind of cap with a piercing tool, when the cap 1 is pushed into the tube container 2 side while being used for the first time, the shaft portion 4 collides with the blind lid 3 to form an opening, Since the above-described through passage is formed in the shaft portion 4, the inner solution can be discharged from the hole to the outside by grasping the tube container 2.
[0005]
[Problems to be solved by the invention]
By the way, in the conventional cap 1 with a punching tool shown in FIG. 11, the opening 5 is broken due to the opening being pushed open from one central point as shown in FIG. 12. For example, there is a problem in that the way the broken line runs is not constant and unstable.
[0006]
On the other hand, in the case of the latter cap with a punching device that allows the inner solution to be discharged while the cap with a conventional punching device is tightened, for example, the periphery of the blind lid 3 is not completely cut, and a part of the cap is a tube. When connected to the container 2 side, the connected tongue piece swings with the extrusion of the inner melt, so that it may block the penetrating path formed in the shaft portion 4, resulting in a smooth adhesive or the like. There was a problem of preventing the discharge.
[0007]
On the other hand, when the blind lid 3 is broken into a large number of small pieces, the small pieces may be mixed into the internal solution.
The present invention has been made in view of such problems, when the opening is formed in the blind lid 3, blanking plate configuration member such as aluminum constituting the blind cover 3 are mixed into the adhesive An object of the present invention is to provide a cap with a punch that can prevent a situation and a situation of blocking a discharge passage.
[0008]
[Means for Solving the Problems]
In the present invention, the shape of the tip of the punch (shaft portion) provided in the cap is an inclined cutting plane that is oblique to the longitudinal direction. By screwing the cap provided with the inclined cutting plane in the pushing direction, the blind lid is not formed with an opening that is radially pushed open from a single point in the center, but the outer periphery of the blind lid is one. A substantially disc-shaped tongue piece can be formed, and the tongue piece hangs down (bends) toward the container along the peripheral surface of the shaft portion provided on the top plate portion. Can do.
[0009]
In order to realize the effect of the present invention, the following configuration is adopted:
(1) A high-viscosity filling the tube container with a cylindrical or cylindrical shaft portion that is screwed into the cap portion of the tube container provided with a blind cover and that extends downward on the top plate. In a cap with a piercing tool provided with a piercing tool for forming a hole for a discharge passage in the blind cover by taking the inner solution made of a substance to the outside for the first time, the shaft portion is brought closer to the plug portion side,
A cap with a punching tool, wherein the shaft portion is formed with a linear inclined cutting surface inclined obliquely at the tip.
(2) The cap with a punching tool according to item 1, wherein a plurality of protrusions are provided unevenly on the linear inclined cut surface.
(3) The cap with a punching tool according to item 1, wherein at least one groove opening in a part of the inclined cut surface is formed in the linear inclined cut surface.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the shaft portion formed downward from the lower surface of the top plate portion located near the middle stage of the cap is formed into a hollow columnar shape or a cylindrical shape, and the distal end region of the shaft portion is longitudinal with respect to the longitudinal direction. An oblique cutting plane that is obliquely formed is formed. Further, even if the substantially disc-shaped tongue piece formed by perforation is completely cut off, a plurality of protrusions are formed at unequal intervals on the inclined cutting plane, and the cut tongue piece is inclined to the inclined cutting plane. There is almost no risk that the through-passage will be blocked due to the contribution that is prevented from adhering to the surface. One or two protrusions are sufficient, but preferably three protrusions are provided. That is, by forming such protrusions on the inclined cutting plane, a gap for the high-viscosity substance to flow out is formed. As a result, this gap serves to secure an outflow passage.
[0011]
【Example】
Embodiments (modes) of the present invention will be described below with reference to the drawings.
1, FIG. 2 and FIG. 3 show a side view, a longitudinal sectional view and a bottom view of a cap with a punch according to the present invention, respectively. In the drawings of the present invention, “up / down / left / right front” and the like are expressions for convenience of explanation.
[0012]
In the cap 10 with a punching tool of the present invention, a small-diameter cylindrical portion 12 is connected to the upper portion of the large-diameter cylindrical portion 11, and the inner peripheral surface of the large-diameter cylindrical portion 11 and the outer peripheral surface of the small-diameter cylindrical portion 12 are provided. Are formed with male threads 13 and 14, respectively. The male screw 14 is formed in a large spiral.
[0013]
At the center of the bottom surface of the top plate portion 15 which is the top plate portion of the large-diameter cylindrical portion 11 and is the substrate of the small-diameter cylindrical portion 12, there is a shaft portion 16 that is substantially cylindrical or substantially cylindrical in a form that hangs downward. Is formed. The tip region of the shaft portion 16 is formed on an inclined cutting plane 17 that is oblique to the longitudinal direction. Further, a through passage 18 that runs in the longitudinal direction is formed inside the shaft portion 16, and this through passage 18 communicates with the outside through a space 19 formed in the small diameter cylindrical portion 12.
[0014]
As the bottom of the large- diameter cylindrical portion 11 approaches downward, it slightly expands outward, and a ratchet 20 is formed on the inner surface of the thin lower end portion 11b. The ratchet 20 enables rotation in only one direction. Further, as shown in FIG. 4, three protrusions 21, 22, and 23 are formed on the inclined cutting plane 17 of the shaft portion 16 so as to be scattered at unequal intervals.
[0015]
The punching tool thrust cap 10 formed in this way is integrally formed from an appropriate plastic material selected from polyethylene, polypropylene, nylon and the like as its material. Next, as shown in FIG. 5, the cap 10 with a punch is screwed onto the outside of the plug portion 31 of the aluminum tube container 30 filled with a high viscosity substance such as an adhesive.
[0016]
Here, a blind cover 32 is attached in advance to the plug portion 31 of the tube container 30. By this blind cover 32, the contents are managed in a sealed state without being exposed to the air in the unused state.
[0017]
When the cap 10 is screwed in preparation for shipment after the tube-shaped container 30 is filled with a high-viscosity substance such as an adhesive, as shown in FIG. 5, the inclined cutting plane 17 of the shaft portion 16 is used. Is isolated from the blind lid 32 to prevent the shaft portion 16 from contacting or piercing the blind lid 32. For this purpose, the spacer 37 shown in FIG. 10 described later is useful.
[0018]
And when a user uses the adhesive agent etc. in this tube container 30 for the first time, as shown in FIG. 6, it pushes in rotating the cap 10 of this invention in the direction to tighten, and tube container 30 Move closer to the side. Finally, the inclined cutting plane 17 reaches the blind lid 32, where it perforates or forms an opening.
[0019]
The inclined cutting plane 17 is cut from the outer peripheral surface of the blind lid 32 sequentially from one point as in the case of cutting canned food by can opener. As a result, the tongue piece 33 cut out as shown in FIG. It is partially connected to the lid 32 and is prevented from being completely separated from the blind lid 32.
[0020]
Moreover, the cut out tongue piece 33 is pressed into the gap between the outer peripheral surface of the shaft portion 16 and the plug portion 31 as shown in FIG. Therefore, a situation in which the tongue piece 33 blocks the opening at the entrance of the through passage 18 is prevented. If this tongue piece 33 is completely separated from the blind lid 4, the tongue piece 33 may float along with the discharge of the high-viscosity material accommodated therein. Since the projections 21, 22 and 23 described above are formed in a scattered state at the lower end of the plane 17, there is a gap between the surface of the inclined cutting plane 17 and the tongue piece 33 as shown in FIG. S is necessarily formed. As a result, the contained high-viscosity substance can be discharged from the gap S to the outside through the through passage 18. Therefore, there is no possibility of taking out the contents.
[0021]
In the cap 10 with a piercing tool of the present invention, once the blind cover 32 of the tube container 30 is pierced, the hole (opening) remains in the state of the pierced hole. Therefore, it is preferable to close this opening when not in use. As a countermeasure, it is preferable that another small cap 35 is mounted on the male screw 14 of the small-diameter cylindrical portion 12. Furthermore, it is preferable that the cross section innermost part of the small cap 35 is fitted into the soft material gasket 36 of substantially "H" shape. The gasket 36 has a lower surface in close contact with the upper end (opening end) edge of the small-diameter portion 12 constituting the cap 10 of the present invention, so that the internal solution is in contact with the outside air other than during use. It is also possible to prevent the situation of leaking outside.
[0022]
When the cap 10 with a punching device of the present invention is mounted on a tube container 30 and shipped or transported (transported), a spacer as indicated by “37” in FIG. And the large-diameter portion 11 in the cap of the present invention. This spacer 37 is useful for avoiding accidental misuse.
[0023]
This spacer 37 is naturally required to be fitted to such an extent that it does not get out of place in the normal storage and transportation mode. In the form of FIG. 10, the member 37 is a paragraph (ring and cylinder) formed by joining a short large-diameter ring and a short small-diameter ring.
[0024]
In order to fully exhibit the function of the spacer 37, it is important to have sufficient rigidity and impact resistance. As such a material, a crystalline thermoplastic resin is preferable, and examples thereof include polyethylene, polypropylene, polyamide resin, and polyethylene terephthalate resin. Among these resin materials, polyethylene and polypropylene are preferable because they are cheaper than their properties.
[0025]
<Modified aspect of the present invention>
As mentioned above, although the Example of this invention was described, this invention is not limited to the said Example at all. For example, a mode (variation mode) in which the above-described embodiment is modified as described below is also within the technical scope of the present invention:
(i) Although a cap in which the through passage 18 is formed in advance in the shaft portion 16 is shown, the present invention does not have a conventional cap, for example, the through passage 18 as shown in FIG. It can also be applied to caps. That is, in the embodiment above Symbol embodiment the shaft portion 16 is formed in a cylindrical shape, the shaft portion 16 may be a cylindrical (solid). In that case, generally, a procedure such as extracting the cap 10 of the present invention from the tubular container 30 after perforating (opening or opening) and pouring the contained high-viscosity substance is generally employed.
[0026]
Further, in the above embodiment, three protrusions are provided in a scattered state on the inclined cutting plane 17, but the number of protrusions is not limited to three. Further, as an alternative means for providing the protrusion, one or more grooves 34 are formed that open to the outside from the through path 18 of the inclined cutting plane 17 toward the outer periphery of the shaft portion 16 as shown in FIG. You can also. If such a groove 34 is provided, the gap S is formed as in the case of FIG. 8 even if the tongue piece 33 completely cut off covers the opening of the through-passage 18 and closes it. With the contribution made, there is almost no possibility that the discharge of the high-viscosity substance will be hindered. In addition, it is preferable to provide the protrusions 21, 22, and 23 and the groove 34 together.
[0027]
Further, as shown in FIG. 10, the porous gasket can be positioned on the base point side of the shaft portion 16, that is, the lower surface of the top plate portion 15 to ensure airtightness (watertightness). Examples of the material for forming the porous gasket include soft elastic polymer materials such as rubbers, thermoplastic elastomers or thermoplastic resins.
[0028]
【The invention's effect】
As described above, according to the cap with a punch according to the present invention, the following effects can be achieved:
(1) With the contribution that the inclined cutting plane is formed at the lower end of the shaft portion, the state of opening the blind lid can be made substantially constant.
(2) Since the incised tongue piece is prevented from being completely cut, it is possible to prevent the tongue piece from blocking the through path even if it is applied to the cap in which the through path is formed. . Therefore, the discharge of the contained high viscosity substance is hardly hindered.
(3) If a plurality of protrusions are formed on the inclined cutting plane, a gap is secured between the top of the protrusion and the tongue piece, so that even if the tongue piece is completely cut off, It is unlikely that the road will be completely blocked.
(4) Similarly, when a groove is formed on the inclined cutting plane, a gap is formed by the groove, so that there is no possibility that discharge of the contained high-viscosity substance is hindered.
