Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a can cap which is used by covering the upper lid of a beverage can for commercial use.

[0002]

[Prior art]

 For commercially available beverage cans such as juice, coffee, tea, or beer, the tab provided on the upper lid is caused to break the notch on the upper lid in advance for breaking the drinking mouth. Most of them are open type, and once they open the mouth, most of them cannot be closed again.

[0003] In addition, the beverage cans often cannot completely drink the beverage at once and leave it, and this tendency is particularly remarkable in infants and the like. In this case, if left unattended, dust may enter the mouth, or in places where there is a lot of vibration or shaking, such as in a car, the beverage may bounce from the mouth or the beverage can may fall over and the beverage may be spilled. It often happens.

[0006] Therefore, there is a lid which is attached to the mouth portion of a beverage can and used when storing the beverage left over, which is generally used.

[0005]

[Problems to be solved by the device]

 However, there are two types of drinking cans, one is that the tab attached to the upper lid is pulled to tear and open the mouthpiece, and the other one is raised and the mouthpiece is placed inside the beverage can. There are two types, one is to fold and open the hole. Especially in the latter case, since the tab and the mouthpiece remain attached to the mouthpiece, the lid is attached to the mouthpiece. In order to do this, it is generally necessary to remove unnecessary tabs and mouthpieces, but it is very troublesome to remove bent mouthpieces and the like inside beverage cans.

An object of the present invention is to solve the above-mentioned drawbacks and to provide a can cap which can be attached to the upper lid of the beverage can with one touch regardless of the type of the mouth of the can.

[0007]

[Means for Solving the Problems]

 The can cap is made of a synthetic resin having elasticity to some extent, and a fitting portion is formed on the outer periphery of the can cap by an outer collar and an inner collar provided at a slight distance inside the can cap. The peripheral wall is provided with a locking projection that is formed obliquely inward, and the outer peripheral wall of the inner collar is provided with protrusions. The lower edge of the inner collar is the upper lid of the beverage can. It was designed to come into contact with the inner edge groove of the.

[0008]

[Work]

 When the can cap is pressed against the edge of the upper lid of the beverage can, the outer collar and the inner collar sandwich the edge of the upper lid, and the locking projections provided around the outer collar have the upper lid of the beverage can. The can cap is securely attached to the upper lid of the beverage can because it fits with the convex portion of the. Further, since the lower edge portion of the inner collar comes into contact with the inner edge groove of the upper lid, the projections provided around the inner collar are strongly pressed against the inner edge wall of the upper lid, and the can cap is brought into close contact with the upper lid.

[0009]

【Example】

 FIG. 1 shows a can cap 1 according to the present invention and a drink can K to which the can cap 1 is attached.

The can cap 1 is a circular synthetic resin cap having elasticity to some extent, and a fitting portion 7 is formed on the peripheral edge by an outer collar 2 and an inner collar 3, and further the outer collar 2 has On the outer peripheral wall, two semi-circular photographs 4 are provided so as to face each other, and as shown in FIG. 2, a hanging string 11 is attached to a hole 6 formed near the center thereof. Further, K is a commercially available beverage can to which the can cap 1 can be attached, and shows a state in which the drinking mouth 5 is opened by the tab 12.

FIG. 3 is a vertical cross-sectional view showing a state in which the can cap 1 is attached to the beverage can K.

On the inner peripheral wall of the outer flange 2, there is provided an inward locking projection 2 a for mounting the can cap 1 on the upper lid 9 of the beverage can K, and the locking projection 2 a is provided. 2a is formed obliquely so that even if the width w of the convex portion 8a of the upper lid 9 varies depending on the type of beverage can, the locking protrusion 2a and the convex portion 8a are securely fitted to each other. Further, a protrusion 3a is provided around the outer peripheral wall of the inner flange 3, and the inner flange 3 is shaped so that the lower edge 3b thereof abuts the inner edge groove 10 of the upper lid 9 of the beverage can K. It is set up.

Since the can cap 1 according to the present invention has the above-described structure, when the can cap 1 is pressed against the edge 8 of the upper lid 9 of the beverage can K, the outer collar 2 and the inner collar 3 are used for the beverage. The edge 8 of the upper lid 9 of the can K is sandwiched, and further, the locking projections 2a provided around the outer collar 2 of the can cap 1 are fitted to the convex portions 8a of the upper lid 9 of the beverage can K. Even if there is some variation in the width w of the convex portion 8a depending on the type of beverage can, since the locking protrusion 2a of the outer collar 2 is formed to be inclined, the bottom edge of the convex portion 8a is formed. The range in which it can contact the locking projection 2a is widened, the variation of the width w is sufficiently absorbed, and the can cap 1 is securely fitted, and the can cap 1 is firmly attached to the upper lid 9. Further, since the protrusion 3a of the inner flange 3 is pressed against the inner edge wall 8b of the upper lid 9 and the lower edge 3b is brought into contact with the inner edge groove 10 of the upper lid 9, the can cap 1 is in close contact with the upper lid 9 and overflows from the drinking mouth 5. The beverage that has come out does not leak out of the can cap 1.

On the contrary, when the attached can cap 1 is to be removed, it can be easily removed by pushing up the photographing 4 protruding from the outer peripheral wall of the outer collar 2.

The diameters of the upper lids of beverage cans for commercial use are unified into almost two types. By providing can caps corresponding to these cap diameters, all beverage cans have the can cap 1. It will be attached.

[0016]

EFFECTS OF THE INVENTION Since the can cap according to the present invention covers the entire upper lid of the beverage can, the mounting is extremely simple by pressing the can cap onto the edge of the upper lid. Further, the outer and inner flanges sandwich the edge of the upper lid, and the locking projections formed on the outer collar and formed obliquely toward the inner side are convex portions of the upper lid of the beverage can. Since the can cap is firmly attached to the upper lid and does not come off, the lower edge portion comes into contact with the inner edge groove of the upper lid, so that the protrusion around the inner collar is attached to the inner edge wall of the upper lid. It is pressed firmly, so the can cap firmly adheres to the top cover, and even if there is vibration or a fall, the drink does not leak from the can cap.

Also, when removing the can cap, you can easily remove it by pushing up the two photographings provided on the outer peripheral wall of the outer collar with your fingers, and attach a string to the hole provided for photographing and attach it to the shoulder If you hang it, it will be very convenient to carry.

Further, the mouth of the used beverage can is left as it is, or the upper lid thereof is cut off with a can opener to make a large opening, and seasonings and various liquids, solids, powders, etc. are put therein, and the can is capped. With the lid on, the contents of the beverage can will not leak even when the beverage can is tilted or inverted, so it can be used as a multipurpose storage container.
