The opener as described above can easily move a member, such as a pull-top or a bottle cap (hereinafter simply referred to as a cap), which is difficult to move when opening the container, and can easily open and close the container. Can be done. However, the various openers described above can only be used for a single type of container. That is, the pull-top opener can be used only for a can with a pull-top, and the cap opener can be used only for a bottle.

Accordingly, two types of openers are required to cope with the opening and closing of both the can body and the bottle body, which makes it difficult to use them properly. In addition, many openers that support only a single type of container have a short handle portion, and are often inconvenient to operate. The present invention has been made in view of such a problem, and an object of the present invention is to easily operate both a pull-top and a cap, and to cope with opening and opening both cans and bottles. It is to provide an opener that can do it.

That is, when the opener according to the present invention is used, each of the above-mentioned openers is used as either a container opening device or the other opener operating device.

Therefore, since one opener is operated by the other opener having a certain length,
The operating force of one opener can be reduced. Further, both the can body and the bottle body can be opened and opened by one opener. The pull-top opener is provided with an insertion portion into which a pull-top can be inserted, and a friction means is provided on an inner peripheral surface of the cap opener so that the inner peripheral surface of the cap opener does not idle between the outer peripheral surface of the cap. Is preferably provided.

[0010] If this means is adopted, the pull-top can be easily inserted into the insertion portion, so that the pull-top opener can easily hook and open the pull-top. Further, since the cap opener is prevented from idling with respect to the cap by the friction means, the cap can be more easily and efficiently opened. Preferably, the insertion portion is provided with a pair of engagement means for engaging the pull top from both front and back surfaces. By employing this means, the pull-top opener can hold the pull-top in a more stable state, and can prevent the pull-top opener from slipping off or coming off from the pull-top when opening the pull-top.

It is preferable that the insertion portion is provided with a contact means for positioning the pull-top insertion position by bringing the tip of the pull top into contact. By employing this means, it is possible to prevent the pull top from moving in the insertion direction in the insertion portion when the pull top is opened. Therefore, the opening of the pull top can be made more reliably. Further, it is preferable that the pull-top opener and the cap opener are provided on the same plane. According to this means, the operation of the opener can be performed most efficiently. Further, since the bulk of the opener itself is reduced, it is easy to handle during packaging, display, and distribution, which is convenient.

The inner peripheral surface of the cap opener may be formed in an arc shape having a notch so that it can be elastically attached and detached along the outer peripheral surface of the bottle cap. If such a configuration is employed, the cap opener can be used for various caps having different diameters, which is preferable.

The insertion portion 8 may be formed between the outer surface 20 and the outer surface 20. In this case, the one member 12 and the outer surface 20 form a pair of engagement means 9.

By the way, the size of the pull top differs depending on the type of the can body, that is, the use such as canned juice and canned food. From such a viewpoint, a plurality of pull-top openers having different sizes of the insertion portion 8 may be provided integrally with the cap opener. FIG. 8 shows a fourth embodiment of the opener according to the present invention. As described above, in order to cope with the pull tops having different sizes, the pull top openers 2 and 2A having the insertion portions 8 and 8A having different sizes may be provided integrally. Further, the outer diameter of the cap of the bottle body also differs depending on the bottle body. For example, the size of a cap differs between a PET bottle for storing a favorite beverage and the like and a bottle for storing a nutrient and the like because of different standards.
In order to cope with such a case, it is desirable that the size of the diameter of the inner peripheral surface of the cap opener is configured to be able to be changed slightly according to the outer diameter of the cap.

From this viewpoint, a fifth embodiment according to the present invention is shown in FIGS. FIG. 9 is a front view of the present embodiment,
FIG. 10 and FIG. 11 are plan views showing a state where the cap opener is externally fitted to the cap. Cap opener 3
The inner peripheral surface 5 is formed in an arc shape having a notch 16 so as to be elastically detachable along the outer peripheral surface of the cap. The length of the arc can be set as appropriate. With this configuration, when the cap opener 3 opens the cap 17 having a small outer diameter, the cap opener 3 is elastically externally fitted to the cap 17, and the shape of the inner peripheral surface 5 is substantially maintained.
6 is fitted to the cap 17 without changing the size much (see FIG. 10).

On the other hand, when opening the cap 18 having a large outer diameter, the notch 16 is greatly opened while the inner peripheral surface 5 elastically increases its diameter, and is attached along the outer peripheral surface of the cap 18. At this time, it is preferable that the inner peripheral surface 5 covers substantially half or more of the outer periphery of the cap 18. Cap 1
8 rotates in the circumferential direction, the inner peripheral surface 5
This is because it is difficult for the tire to idle (see FIG. 11).
After the cap opener has finished opening the cap,
The inner peripheral surface 5 is elastically deformed again and is removed from the outer peripheral surface of the cap.

The diameter of the inner peripheral surface described above can be appropriately set according to the standard of the PET bottle and the standard of the base.
Further, as the material of the above-described opener, a synthetic resin, a metal, or the like can be used. In particular, from the viewpoint of durability and rigidity,
A hard synthetic resin such as ABS is preferred. In addition, the fifth
When the cap opener is elastically deformed as in the embodiment, it is preferable that the cap opener is formed of a material that is easily elastically deformed. Further, when the cap opener is formed of metal or the like and has sufficient rigidity, the cap opener can also be used as a bottle opener.

The outer shape of the cap opener is arbitrary. It can also be formed in the shape of a character or the like in accordance with fashion or the like. This is because if the inner surface in contact with the outer surface of the cap has a circular shape or an arc shape that matches the shape of the outer periphery of the cap, the outer surface can be fitted to the cap. In addition, the pull-top that can be opened by the pull-top opener according to the present invention includes both a type that is separated from the can body after being opened and a type that remains attached to the can body without being separated.
