Description

  The present invention relates to a can with an overcap used for accommodating and distributing powdered milk, for example.

  Conventionally, metal cans containing powdered milk have been used, and the top of the cans is made of synthetic resin to reclose the cans after opening and to prevent unauthorized opening at the distribution stage. An overcap is attached (for example, refer to JP 2001-341762 A). FIG. 7 is a schematic front view showing a conventional example of this type of overcap can, and FIG. 8 is a schematic sectional view of a partial region thereof. The overcap can generally indicated by reference numeral 1 includes a straight can 2 for containing powdered milk and the like, and an overcap 3 attached to the top of the can. In the present specification, for straight cans and overcaps, expressions such as “top”, “upper”, “lower”, “upper edge”, “lower edge”, etc. are used, These expressions shall refer to a state where a straight can or an overcap is placed so that each top surface portion is on top.

  The straight can 2 includes a cylindrical body portion 4, a metal top surface portion 6 fixed to the upper end of the body portion 4 by a winding fastening portion 5, and a lid member 7 that closes an opening formed in the top surface portion 6. The winding fastening part 5 is formed so that a part thereof is located outside the trunk part 4, and the diameter of the top face part 6 is substantially equal to the inner diameter of the trunk part 4. This structure has an advantage that a large opening can be formed in the top surface portion 6 and the contents can be easily taken out. The overcap 3 is integrally formed of a synthetic resin such as polyethylene or polypropylene, and includes a top surface portion 8a and a cylindrical portion 8b integrally connected to the outer periphery thereof, and a winding portion at the top of the straight can 2 5 and a cap body 8 that can be fitted and attached to the lower end edge of the cylindrical portion 8b of the cap body 8 via a tearable portion 9 that can be torn, and the lower end edge 10a of the body portion 4 of the straight can 2 A pill fuzzy proof band 10 that can be attached in close contact with the outer surface, a knob portion 11 that is used when the pill fuff proof band 10 is torn, and the like are provided. In order to open the can 1 with an overcap having this structure, first, the grip portion 11 of the overcap 3 is grasped and pulled, and the weak portion formed in the vicinity of the grip portion 11 of the pill faproof band 10 is broken. By tearing the tearing portion 9 between the pill fuff proof band 10 and the cap main body 8, the pill fuff proof band 10 is removed from the cap main body 8, and then the cap main body 8 is removed from the straight can 2, and the straight can It is necessary to perform an operation of opening the top surface portion 6 of the second. In this way, the use of the overcap 3 with a pilfa proof band prevented unauthorized opening.

However, the overcap can with this structure has a problem. In other words, the overcap 3 is removed from the straight can 2 without breaking the pillfapproof band 10 by hooking a finger on the lower edge 10a of the pillfapproof band 10 of the overcap 3 and pushing it up. For this reason, it is mischievous to remove the overcap 3 from the straight can 2 by tampering at the store, etc., and after attaching the overcap 3 to the straight can 2 as it was after opening the straight can 2 In this case, there was a problem that it was impossible to identify that the can 1 with an overcap was crafted from the appearance.
JP 2001-341762 A

  The present invention has been made in view of such problems, and in a can with an overcap having a structure in which an overcap provided with a pill fuffproof band is attached to a straight can, the overcap can be removed without breaking the pillfap proof band. It is an object to prevent removal from a straight can.

  The invention according to claim 1 to solve the above-described problems is a cylindrical can, a straight can having a top surface having a diameter substantially equal to the inner diameter of the torso, and a top of the straight can. In the can with an overcap, the overcap includes a cap body that can be fitted and attached to a top portion of the straight can, and a tearable portion that can be torn at a lower end edge of the cylindrical portion of the cap body. The straight can is at least in the proximity region below the lower edge of the pill fuff proof band of the overcap, and the maximum outer diameter is the lower edge of the pill fuff proof band. As a configuration that has a convex rib that is equal to or greater than the outer diameter, and prevents access to the lower end edge of the pill fuffproof band from below And gist the can with overcap, wherein Rukoto.

  According to a second aspect of the present invention, in the can with an overcap according to the first aspect of the present invention, the cylindrical first convex portion in which the convex rib is formed in a region facing the inner surface of the pill fuffproof band. And a cylindrical second convex portion having a diameter larger than that of the first convex portion at a position following the lower side of the first convex portion and below the lower end edge of the pill fuff proof band. The inner surface of the pill fuffproof band is fitted or close to the cylindrical surface of the first convex portion, and the outer peripheral surface of the second convex portion is attached to the straight can. It has the shape which becomes a cylindrical surface of the same outer diameter as the outer diameter.

  According to a second aspect of the present invention, in the can with an overcap according to the first aspect of the present invention, the cylindrical first convex portion in which the convex rib is formed in a region facing the inner surface of the pill fuffproof band. And a second convex portion having a tapered surface that is formed at a position following the lower side of the first convex portion and that expands downward, and the pill fuff proof band is attached to the straight can. In this state, the inner surface of the pill fuff proof band is fitted or close to the first convex portion 33a, the lower end edge is fitted to the tapered surface of the second convex portion, and the outer peripheral surface is reduced in diameter downward. It has a shape to be a surface.

  The can with an overcap having the above structure has a convex rib formed on the body portion of the straight can so that the lower end edge of the pill fuff proof band cannot be accessed from below. For this reason, the overcap cannot be removed from the straight can without breaking the pill fuff proof band, preventing unauthorized opening in the distribution stage, and the straight can Has an effect that it does not impair the merit of the straight can because the convex rib is simply formed.

  1 is a schematic front view of a can with an overcap according to a preferred embodiment of the present invention, FIG. 2 is a schematic plan view thereof, and FIG. 3 is a schematic cross-sectional view of a main portion of the can with an overcap. The overcap can generally indicated by reference numeral 21 includes a straight can 22 for containing powdered milk and the like, and an overcap 23 attached to the top of the can. Like the conventional straight can, the straight can 22 used here is a metal cylindrical barrel portion 24 and a metal top surface portion 26 fixed to the upper end of the barrel portion 24 by a winding fastening portion 25. And a lid 27 that closes the opening formed in the top surface portion 26, etc., but unlike the prior art, a convex rib 33 is formed in a region near the upper end of the cylindrical body portion 24. Yes. The shape of the convex rib 33 will be described later. The structure and shape of the other region excluding the convex ribs 33 of the straight can 22 are the same as those of the conventional straight can 2 (see FIGS. 7 and 8), and a part of the tightening portion 25 is a body portion 24 (convex). The top surface portion 26 is formed so as to be positioned outside the region (excluding the ribs 33), and the diameter of the top surface portion 26 is substantially equal to the inner diameter of the body portion 24 (region excluding the convex ribs 33). With this structure, the same merit as a conventional straight can can be enjoyed. That is, since this straight can 22 can form a large opening in the top surface portion, it is easy to take out the contents, and in manufacturing, the existing device can be used as it is as a tightening device for attaching the top surface portion. In addition, it is possible to enjoy the merit that a conventionally used top cap can be used as a top cap for forming the top portion.

  The overcap 23 is formed integrally with a synthetic resin such as polyethylene or polypropylene, and includes a top surface portion 28a and a cylindrical portion 28b integrally connected to the outer periphery thereof, and a winding portion at the top of the straight can 22 25, a cap body 28 that can be fitted and attached to 25, a pill proof band 30 that is connected to a lower end edge of the cylindrical portion 28b of the cap body 28 via a tear portion 29 that can be torn, and the pill fuff proof band. A knob portion 31 used for 30 tears is provided. The convex rib 33 formed on the body portion 24 of the straight can 22 is a cylindrical first convex formed on a region facing the inner surface of the pill fuffproof band 30 of the overcap 23 attached to the straight can 22. Cylindrical second formed with a larger diameter than the first convex portion 33a at a position following the portion 33a and below the first convex portion 33a and below the lower edge of the pill fuff proof band 30 Convex part 33b is provided. In the state where the pill fuff proof band 30 is attached to the straight can 22, the inner surface of the pill fuff proof band 30 is a cylindrical surface fitted to the cylindrical surface of the first convex portion 33a, and the outer peripheral surface 30a is the second convex portion. It is made into the shape used as the cylindrical surface of the same outer diameter as the outer diameter of 33b. Therefore, in the state where the overcap 23 is attached to the straight can 22, as can be seen from FIG. 3, the pill fuffproof band 30 is formed on the step formed by the first convex portion 33 a and the second convex portion 33 b of the convex rib 33. A second convex portion 33b having an outer diameter equal to the outer diameter of the lower end edge of the pill fuzz proof band 30 is located immediately below the lower end edge of the pill fuff proof 30 so as to be in a fitted state. Access to the lower edge of 30 from below is prevented.

  As shown in FIGS. 1 to 3, the can 21 with an overcap having the above configuration is circulated with the overcap 23 attached to the top of the straight can 22. At this time, since the pill fuffproof band 30 is almost entirely fitted into the first convex portion 33a formed on the body portion 24 of the straight can 22 and supported by the first convex portion 33a, Therefore, even if some external force is applied to the pill fuffproof band 30 in the center direction of the straight can 22, the external force is received by the first convex portion 33 a, and a large force does not act on the tear portion 29. For this reason, the trouble that the tearing part 29 fractures can be avoided. Further, even if someone is mischievous and tries to remove the overcap 23 from the straight can 22, the second convex portion 33 b is located just below the lower edge of the pillfapproof band 30, so that the pillfuffproof band Therefore, it is almost impossible to remove the overcap 23 from the straight can 22 by hooking the finger on the lower edge of the pill fuffproof band 30. Thus, it is safe because the entire overcap 23 cannot be removed from the straight can 22 by mischief.

  When opening the can 21 with the overcap, the grip portion 31 of the overcap 23 is grasped and pulled to break the weak portion formed in the vicinity of the grip portion 31 of the pill fuff proof band 30. By tearing the tearing portion 29 between the cap body 28 and the cap body 28, the pill fuff proof band 30 is removed from the cap body 28. Thereafter, the cap body 28 is removed from the straight can 22, and the top surface portion 26 of the straight can 22 is removed. It is sufficient to perform an operation of opening. After the necessary amount of the contents of the straight can 22 has been taken out, the straight can 22 can be reclosed with the cap body 28 by fitting and attaching the cap body 28 to the top of the straight can 22 again.

  In the above-described embodiment, the shape and dimensions of the pill fuffproof band 30 and the shape of the convex rib 33 are set so that the substantially entire area of the pill fuff proof band 30 is fitted to the cylindrical first convex portion 33a. Although the dimensions are determined, the shape and dimensions of the pill fuff proof band 30 and the convex ribs 33 are not limited to this, and can be changed as appropriate. Only the first convex portion 33a is fitted and supported, or the inner surface of the pill fuffproof band 30 is located close to the first convex portion 33a, and a minute amount (for example, 0) It is possible to facilitate the attachment of the overcap 23 to the straight can 22 by forming a gap (about .1 to 0.5 mm). In this case, it is preferable to make the gap as small as possible because the pill fuffproof band 30 is less likely to move in the diametrical direction and the finger is less likely to be caught on the lower edge. Moreover, as shown in FIG. 4, you may make it the 3rd convex part 33c formed in the upper end of the 1st convex part 33a of the convex rib 33, and the pill fuffproof band 30 becomes difficult to remove | deviate. Further, the outer diameter of the second convex portion 33b may be larger than the outer diameter of the outer peripheral surface 30a of the pill fuff proof band 30, so that the finger is further applied to the lower end edge of the pill fuff proof band 30. It becomes difficult to catch.

  FIG. 5 is a schematic cross-sectional view showing the main part of an overcap can according to another embodiment of the present invention, and the same reference numerals are used for the same or similar parts as the overcap can shown in FIGS. It is attached. In the can 21 with an overcap according to the embodiment shown in FIG. 5, the first cylindrical rib formed in the region facing the inner surface of the pill fuffproof band 30 is formed on the body portion 24 of the straight can 22. It has the convex part 33a and the 2nd convex part 33b which has the taper surface 33ba which is formed in the position following the lower side of the first convex part 33a, and expands the diameter downward. In addition, the pill fuff proof band 30 formed on the overcap 23 is attached to the straight can 22 and at least a part of the inner surface of the pill fuff proof band 30 is fitted or close to the first convex portion 33a. The lower end edge is in a state of being fitted to the tapered surface 33ba of the second convex portion 33b, and the outer peripheral surface 30a of the pill fuffproof band 30 is formed into a tapered surface that is reduced in diameter downward. Therefore, also in this embodiment, when the overcap 23 is attached to the straight can 22, the lower end edge of the pill fuff proof band 30 is fitted to the tapered surface 33ba of the second convex portion 33b, and the pill fuff proof is obtained. A second convex portion 33b having an outer diameter larger than the outer diameter of the lower end edge of the pill fuff proof band 30 is located immediately below the lower end edge of the pill fap proof band 30 from below the lower end edge of the pill fuff proof band 30. Is blocking access.

  Even in the can 21 with an overcap having the configuration shown in FIG. 5, even if some external force is applied to the pill fuff proof band 30 toward the center of the straight can 22 in the distribution stage, the external force is received by the first convex portion 33a. As a result, a large force does not act on the tearing portion 29. For this reason, the trouble that the tearing part 29 fractures can be avoided. Further, even if someone is mischievous and tries to remove the overcap 23 from the straight can 22, the second convex portion 33 b is located just below the lower edge of the pillfapproof band 30, so that the pillfuffproof band The lower end edge of 30 cannot be caught by a finger, and in particular, since the outer peripheral surface 30a of the pill fuff proof band 30 is a tapered surface whose diameter is reduced downward, the lower end edge of the pill fuff proof band 30 is further layered. For this reason, it is almost impossible to remove the overcap 23 from the straight can 22 by putting a finger on the lower end edge of the pill fuffproof band 30. Thus, it is safe because the entire overcap 23 cannot be removed from the straight can 22 by mischief.

  Even when the pill fuffproof band 30 and the convex rib 33 shown in FIG. 5 are used, the third convex portion 33c is formed on the upper end of the first convex portion 33a of the convex rib 33 as shown in FIG. The pill fuffproof band 30 may be difficult to come off.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this embodiment, and can be appropriately changed within the scope of the claims.
