Abstract

PURPOSE:To reduce the number of parts, simplify the manufacture processes and improve the yield by a method wherein an outer side cylindrical body which has a closed top and open bottom is integrally formed, and around the bottom side open part, a plurality of slipping out preventive steps are formed in the peripheral direction under a divided condition. CONSTITUTION:When an inner side cylindrical unit B is fitted in an integral-type synthetic resin outer side cylindrical body A, which has an closed top and open bottom, by pressing parts where both slipping out preventive steps 1a, 1b are not located on the lower side open periphery of the outer side cylindrical body A, an elastic deformation is forcibly given to the lower side open part, and under this condition, the inner side cylindrical unit B is forcibly fitted in the outer side cylindrical body A. Since the outer side cylindrical body A, which has a closed top and open bottom, is constituted of an integral molding made of a synthetic resin, the number of parts can be reduced, the manufacture processes of the outer side cylindrical body A itself can be simplified, and the improvement of the yield can be achieved.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a method for making crowns of beer bottles, jersey bottles, etc.
It can be removed by simply pressing down on the operating section (
A push-down bottle opener configured to be able to remove the bottle, specifically, inside the outer cylindrical body with the upper side closed and the lower side opened,
An inner cylindrical unit equipped with a bottle opener mechanism is inserted so as to be slidable in the vertical direction, that is, in a state where it is always urged downward and can be forcibly moved upward; In order to prevent the bottle from slipping out downwardly from the outer cylindrical body, a push-down bottle opener is provided with a pull-out prevention step that protrudes inward around the lower opening of the outer cylindrical body. Concerning vessels.

[Prior Art] This type of push-down bottle opener has already been developed in 1932 by the present inventor.
The date of June 25, 2017 was proposed in the order of utility model registration, etc., and has become popular in the world as the product name "Centre" (registered trademark of the inventor), and its basic The configuration is as shown in Fig. 3 (a) and (b).

That is, to explain the general structure of the push-down bottle opener illustrated in Fig. 3 (a) and (b), as shown in Fig. 3 (b), it has an upper opening and a lower opening. A cylindrical body 1 is formed with a pull-out prevention step 1a (the function of which will be explained later) that protrudes inward over the entire circumference of the cylindrical body 1, and a push-down bar 2a (the function of which will be explained later) is formed on the lower surface side. (will be explained later), and an upper lid body 2 that is fitted and joined to the upper opening of the cylindrical body 1 to close the upper opening. Inside the open-shaped outer cylindrical body A, an inner cylindrical unit B equipped with a bottle opener mechanism as described later is slidably movable in the vertical direction, that is, it is always urged downward and upward. It is inserted so that it can be forcibly moved to the side. Note that this inner cylindrical unit '7B is always urged downward as described above, but as shown in the figure, the lower opening in the outer cylindrical body A is formed around its lower end. Since it is latched to the extraction-preventing stepped portion la formed around the entire circumference of the portion, it will not slip out downward from the outer cylindrical body A.

Next, the general structure of the bottle opener mechanism provided in the inner cylindrical unit B will be explained. A member 4 and a crown hook member 6 which is pivotally connected and suspended via a horizontal pin 5 at one end of the lever member 4 are provided, and the lever member 4
For example, a tension coil spring 7 that always urges the free end (the right end in the figure) upward, and the tip part (the lower end in the figure) of the crown hook member 6 are always pushed inward (inside the inner cylinder unit B). For example, an expanding coil spring 8 is provided to bias the bottle C toward the mouth side of the bottle C which is relatively inserted into the bottle C. Note that the free end portion of the lever member 4 (
The right end (in the figure) is always in contact with the lower end of the push-down rod 2a hanging down from the lower surface of the upper lid 2, and its position is regulated. Therefore, the tension coil spring 7 also has the function of always urging the entire inner cylindrical unit B downward as described above. Further, in the figure, reference numeral 9 denotes one end of the crown ◯ that is fitted into the mouth of the bottle C that is relatively inserted from the lower opening of the inner cylindrical unit B, on the side opposite to the crown hooking member 6 side. It is an intermediate wall part provided to support the upper surface part, and 1
0 is a magnet that attracts the crown 0 that has been pulled out (removed) from the mouth of the bottle C as described below to prevent it from falling downward, and lb is a magnet that is attached to the outside of the bottle C. This is a reference protrusion formed in the vertical direction on the inner circumferential surface of the cylindrical body 1 of the cylindrical body A, and although it is not shown in the figure, the lower outer circumferential surface of the upper lid body 2 and the outer circumferential surface of the inner cylindrical unit) B. A notch or groove corresponding to the reference protrusion 1b is formed in the cylindrical body 1, and thereby the positional relationship in the circumferential direction between the cylindrical body 1, the upper lid body 2, and the inner cylindrical unit B is uniquely determined. There is.

To explain how to use the push-down bottle opener configured as above, first, as shown by the imaginary line in FIG. With the opening of the bottle C relatively inserted into the inside of the inner cylindrical unit B from the lower opening, the whole push-down bottle opener is placed over the bottle C.
Lower the upper end of the opening (that is, the upper surface of one end of the crown 0 on the side opposite to the crown hooking member 6 side) to the position where it comes into contact with the lower surface of the intermediate wall part 8 in the inner cylinder unit B, and then Continuing from this state, when the outer cylindrical body A serving as the operation part is forcibly pushed down as shown by the white arrow in the figure, the third
As shown in the figure, the tension coil spring 7
The 't1 end of the lever member 4 is pushed down by the lower end of the push-down rod 2a against the urging force of Eventually, the tip of the crown hooking member 6 reaches a state where it engages with the lower end portion of the crown O, and by continuing to rise from this engaged state, the side of the crown hooking member 6 on the crown 0 The crown 0 can be pulled out (removed) with a relatively light operating force by the principle of leverage using the contact point of the top surface of the one end side opposite to the lower surface of the intermediate wall section 8 as a fulcrum. Then, the removed crown ○ is attracted by the magnet 10 and held in the inner cylinder unit B.

[Problem to be solved by the invention]

However, even with the above-mentioned push-down bottle opener, which is extremely easy to operate and convenient, there are still problems as follows.

In other words, a push-down bottle opener equipped with a mechanical structure to provide such convenience is inevitably more expensive than a general simple bottle opener, but the present invention Until now, manufacturers have repeatedly made various ingenious efforts to reduce the number of parts, simplify the manufacturing process, and downsize the overall structure, resulting in products that are quite simple and compact, as well as at reasonable costs, as explained earlier. However, in order to provide this push-down bottle opener at a lower price and spread it, we had to
We must achieve further reductions in manufacturing costs.

Based on this point of view, various studies have been conducted on the push-down bottle opener of the conventional configuration described above, and as a result, it has been found that there is room for improvement in the following points.

In other words, in the conventional push-down bottle opener described above, the inner cylindrical unit B, which is equipped with a bottle opener mechanism, is placed inside the outer cylindrical body A that is closed at the top and opened at the bottom. In order to prevent the insertion from occurring, as described above, the outer cylindrical body A is provided with an extraction-preventing stepped portion that has an upper opening and protrudes inwardly over the entire circumference of the lower opening. 1a is formed, and an upper lid body 2, which has a push-down rod 2a hanging down and connected to the lower surface side, and is fitted and joined to the upper opening of the cylindrical body 1 to close the upper opening. As shown in FIG. 4, first, the inner cylindrical unit B is inserted into the cylindrical body 1 from its upper opening, and then, as shown in FIG.
Fitting the upper lid 2 into the upper opening of the cylindrical body 1,
For example, a manufacturing process was adopted in which the parts were joined by ultrasonic or high-frequency welding means, or joining means using an adhesive. It would be even better if the inner cylindrical unit B could be inserted into the outer cylindrical body A while forming the body A into an integral body without using the special upper lid body 2 as described above. Further reduction in the number of parts and simplification of the manufacturing process can be achieved, and an efficient ultrasonic welding method is adopted when fitting and joining the upper lid body 2 to the upper opening of the cylindrical body l. In this case, the upper part of the cylindrical body l and the upper lid body 2 may be deformed due to the heat effect of ultrasonic or high-frequency welding, or poor bonding may occur, resulting in a poor product yield. can also be resolved.

The present invention has been made as a result of intensive research based on the above-mentioned considerations, and its purpose is to form an outer cylindrical body with an upper side closed and a lower side open type into an integral body, and to
By making it possible to insert the inner cylindrical unit inside the outer cylindrical body, it is possible to further reduce the number of parts, simplify the manufacturing process, and improve yield. The object of the present invention is to provide a convenient push-down bottle opener with excellent operability at a lower cost and to popularize it.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a push-down bottle opener having the basic configuration as described at the beginning, in which the outermost cylindrical body is closed at the upper side and opened at the lower side. In order to make it easier to forcibly elastically deform the surrounding portion of the lower opening, the extraction preventing steps formed around the lower opening are scattered in a plurality of pieces in the circumferential direction. It is characterized by the fact that it takes the following measures: either it is formed in the same state as the opening, or a plurality of vertical slits are formed around the lower opening.

[Effect]

The effects achieved due to this characteristic configuration are as follows.

That is, in the push-down bottle opener according to the present invention, as will become clearer from the description of the embodiments described below,
Upper Closure/Lower Opening A plurality of extraction prevention steps are formed around the lower opening of the outer cylindrical body and are scattered in the circumferential direction. By forming a plurality of vertical slits around the side opening, the area around the lower opening in the outer cylindrical body is configured to be easily forcedly elastically deformed, so that the bottle opener mechanism can be easily deformed. The inner cylindrical unit is easily inserted into the outer cylindrical body by forcibly fitting the inner cylindrical unit from the lower opening side while forcibly elastically deforming the area around the lower opening of the outer cylindrical body. Therefore, the upper-side closing/lower-side opening outer cylindrical body can be replaced with a separate cylindrical body and an upper lid body for closing the upper opening, respectively, as in the past. There is no need to go through the time-consuming manufacturing process of manufacturing and joining these two parts by ultrasonic or high-frequency welding means or joining means using an adhesive, for example, injection molding of synthetic resin or thin metal sheet. It is now possible to construct the parts all at once through integral molding such as press molding, which enables a further reduction in the number of parts and simplification of the manufacturing process compared to conventional methods. The problem of poor yield due to thermal deformation or poor bonding that would otherwise occur when ultrasonic or high frequency welding means is employed does not occur.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described based on the drawings (FIGS. 1 and 2).

FIGS. 1A and 1B show a longitudinal sectional front view and a bottom view of the outer cylindrical body A, which is the main part of the push-down bottle opener according to the first embodiment.

As previously explained in detail using FIG. 3, this outer cylindrical body A has an inner cylindrical unit 1-B (not shown here) provided with a bottle opener mechanism in the vertical direction. It is inserted in a slidable manner, that is, in a state where it is always urged downward and can be forcibly moved upward, and in a state where it cannot come out downward. There is.

That is, in this example, the outer cylindrical body A is an integrally molded synthetic resin product with an upper side closed and a lower side open, that is, it is composed of only the - element, and the surrounding portion of the lower side opening is , an inner cylindrical unit) B (not shown) inserted into the outer cylindrical body A by means described in detail later.
In this example, a plurality of ejection-preventing stepped portions 1a for preventing the material from slipping out downward are scattered in the circumferential direction, instead of over the entire circumferential portion as in the conventional configuration. Then, the two ejection-preventing step portions 1a, l
a are formed at positions facing each other. Therefore, the portion around the lower opening in the outer cylindrical body A is easily forced to undergo elastic deformation. In addition, in the figure, 2a
3 is a push-down rod, and as explained in detail using FIG. The inner cylindrical unit) B functions to push down the free end of the lever member 4, and
Reference numeral 1b denotes a reference projection formed vertically on the inner surface of the outer cylindrical body A. Although not shown in the figure, the outer peripheral surface of the inner cylindrical unit B has a notch or a notch corresponding to the reference projection 1b. A groove is formed, thereby uniquely determining the positional relationship between the outer cylindrical body A and the inner cylindrical unit B in the circumferential direction.

In the push-down bottle opener configured as described above, the upper-side closing/lower-side opening outer cylindrical body A is not a combination of the two elements of the cylindrical body and the upper lid body as in conventional ones. Since it is composed of an integrally molded synthetic resin product, it is possible to reduce the number of parts, simplify the manufacturing process of the outer cylindrical body A itself, and improve the yield. When inserting the inner cylindrical unit B inside, the following method is very simple and reliable, compared to the conventional process which is troublesome, uncertain, and has yield problems, as explained in detail using FIG. 4. Only the process is required.

That is, when inserting the inner cylindrical unit B inside the synthetic resin outer cylindrical body A, which is an integral type with an upper side closed and a lower side open type, as described above, the outline arrows X, As shown by Fig. 1 (opening) is forcibly deformed elastically in the directions shown by arrows Y and Y (in other words, the part where the two extraction prevention steps 1a and la are present is shaped into an ellipse with a slightly enlarged diameter). In this state, the inner cylindrical unit B is forcibly pushed (inserted) into the outer cylindrical body A. Therefore, in this case, the cylindrical body is There is no need for a post-process of joining the upper lid to the upper opening.

In addition, the number, position, individual width, etc. of the step portions 1a for preventing extraction, which are formed scattered around the lower opening in the outer cylindrical body A, are based on the lower opening in the outer cylindrical body A. It can be freely selected within a range that allows the required forced elastic deformation to occur in the surrounding area of the part.

Figures 2A and 2B show a longitudinal sectional front view and a bottom view of the outer cylindrical body A, which is the main part of the push-down bottle opener according to the second embodiment.

In this second embodiment, a plurality of (in this example, 8) vertical slits S... are formed. In this case, the extraction prevention step 1a formed over substantially the entire circumference of the lower opening in the outer cylindrical body A is as shown in FIG. It is desirable to form a guide surface for forcibly fitting the inner cylindrical unit B by attaching a suitably rounded cam surface to the outer surface 1a' of the inner edge.

That is, in the push-down bottle opener configured as described above,
When inserting the inner cylindrical unit B inside the outer cylindrical body A, press the upper end of the inner cylindrical unit against the lower opening of the outer cylindrical body A and push it inside. As shown by the arrow Z... at the mouth, the diameter of the entire lower opening of the outer cylindrical body A can be expanded, and from this state, the inner cylindrical unit) B is forced to the outside. It can be fitted by pushing it into the cylindrical body A. The rest of the configuration is the same as that of the first embodiment, so components having the same functions are designated by the same reference numerals and their explanations will be omitted.

In addition, in each of the above embodiments, the outer cylindrical body A
This is an integral molded product made of synthetic resin.
It may also be configured as an integrally molded product of other materials such as metal.

[Effects of the Invention] As is clear from the above detailed description, the push-down bottle opener according to the present invention has an outer cylindrical body with an upper closed and lower open type formed integrally. The extraction prevention step formed around the lower opening is divided into a plurality of parts in the circumferential direction, or the extraction prevention step part formed around the lower opening is divided into a plurality of parts in the vertical direction. By forming a slit, the area around the lower opening of the outer cylinder can be forcibly deformed easily, making it easier to forcibly deform the parts. This is a significant improvement in that it is possible to reduce the number of parts, simplify the manufacturing process, and improve yield, making it possible to provide a convenient push-down bottle opener with excellent operability at a lower cost than before. Excellent effects have been demonstrated.
