Description

Beverage Can Sealing Device The present invention relates to a sealing device for beverage cans. Generally, beverages are supplied to consumers in containers made of aluminum to prevent leakage during distribution. In order for a user to drink the beverage stored in the beverage can, they lift the tab located on the top surface of the beverage can to form an opening in the top plate of the can, and drink the beverage through the opening. However, in the case of beverage cans, there is a problem in that it is difficult to seal the can after an opening is formed on the top of the can using a tab. In order to resolve such problems, Utility Model 20-2022-0002788, a beverage can with a foldable lid (disclosure date November 24, 2022), discloses a technology that closes the open opening of a can by allowing the lid to be opened from a folded state to an unfolded state after opening a can containing a beverage. However, the lid of the beverage can with a foldable lid according to Public Utility Model 20-2022-0002788 has a complex structure, is difficult to reuse after one use, and has problems that make it difficult to apply to existing commercially available cans. FIG. 1 is an external perspective view of a beverage can sealing device according to an embodiment of the present invention. Figure 2 is an unfolded view of Figure 1. Figure 3 is a cross-sectional view taken along line II' of Figure 1. Figure 4 is a cross-sectional view illustrating a beverage can sealing device combined with a beverage can. The present invention described below is capable of various modifications and may have various embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In describing the invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the invention. The terms used in this patent are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this patent, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Additionally, terms such as "first," "second," etc., may be used to distinguish and describe various components, but said components shall not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. In addition, if at least two different embodiments are described in this patent, each embodiment may use all or part of its components in combination and mixed with one another without further description, as long as it does not deviate from the technical concept of the present invention. FIG. 1 is an external perspective view of a beverage can sealing device according to an embodiment of the present invention. FIG. 2 is an exploded view of FIG. 1. FIG. 3 is a cross-sectional view taken along the line I-I' of FIG. 1. FIG. 4 is a cross-sectional view showing the beverage can sealing device coupled to a beverage can. Referring to FIGS. 1 to 4, the beverage can sealing device (400) includes a band member (100), a sealing member (200), and a connecting member (300). Figure 1 illustrates a beverage can (10). The beverage can (10) includes a beverage body (1) in which a beverage is stored in a tubular shape, a stopper (5) formed on the upper surface of the beverage body (1), and a tab (3) connected to the stopper to separate the stopper (5) from the upper surface of the beverage body (1) to form an opening (7) on the upper surface of the beverage body (1). The band member (100) of the beverage can sealing device (400) is formed in an annular band shape. The band member (100) is made of a material having elasticity. The band member (100) can be made of, for example, an elastic rubber material, an elastic synthetic rubber material, and an elastic synthetic resin material. The size of the elastic band member (100) is formed to be smaller than the size of the beverage body (1) of the beverage can (10), and the band member (100) is stretched and inserted into the outer surface of the beverage body (1) and then adheres to the outer surface of the beverage body (1).
