no. 1 Embodiment approach

[0039] figure 1 It is a cross-sectional view schematically showing the structure of the disk-shaped flat battery 1 according to the first embodiment of the present invention. Here, the disk-shaped flat battery 1 refers to a thin disk-shaped battery such as a button battery or a button battery. In addition, the type of the battery is not limited, and may be, for example, a primary battery or a secondary battery. Hereinafter, the circular flat battery 1 is simply referred to as a "battery". also, figure 1 The battery exemplified in is a lithium battery.

[0040] Such as figure 1 As shown, the negative electrode 2 with lithium or lithium alloy as the negative electrode active material and the positive electrode 3 with fluorinated graphite as the positive electrode active material are accommodated in the battery case 5 together with the electrolyte solution through the separator 4 . The opening of the battery case 5 is sealed by a sealing plate 6 with an annular gasket 7 inte...

no. 2 Embodiment approach

[0062] Figure 7 (a) to (c) are sectional views showing the steps of holding the battery 1 in the second embodiment of the present invention in the holding case (resin case) 10 . in addition, Figure 8 is a plan view of the holding case 10 . In addition, the battery 1 only shows the positive electrode surface 5 and the negative electrode surface 6 .

[0063] Such as Figure 7 (a) and Figure 8 As shown, the holding case 10 has an opening 12 allowing the battery 1 to be taken in and out from the electrode surface of the battery 1 , a side surface 13 and a bottom surface 14 for holding the side surface and / or bottom surface of the battery 1 . Thereby, the storage part 11 for housing the battery 1 is ensured in the holding|maintenance case 10. As shown in FIG. In addition, the holding case 10 has an annular protruding portion 15 protruding radially inward from the opening end surface 13 a of the side portion 13 . Here, the protruding portion 15 is supported by the opening e...

Abstract

The present invention is a holding case (10) for holding a disc-shaped, flat-type cell (1). The flat-type cell (1) is configured such that a sealing plate (6) which serves as a first electrode face and a cell case (5) which serves as a second electrode face are sealed via a ring-shaped gasket (7). The holding case (10) has a box-shaped form made from resin and having an open end face (13a) which enables removal from the electrode face of the flat-type cell (1); a protruding part (15) for protruding into the inside in the radial direction from the rim part of the open end face (13a) side is formed in a side face part (13) of the holding case (10); and the protruding part (15) is formed at a position which is separated from a bottom face part (14) of the holding case (10) by a distance which is greater than the thickness of the flat-type cell (1).

Description

technical field [0001] The present invention relates to a battery holding case for holding a disc-shaped flat battery, and a battery package having a storage chamber for storing the case. Background technique [0002] Disc-shaped flat batteries such as button batteries have been reduced in size and thickness, so they may be swallowed by young children. [0003] Therefore, electronic equipment powered by a button battery is provided with a locking mechanism in a storage room for storing the button battery to prevent accidental swallowing so that infants cannot easily take out the battery. [0004] However, even if the battery is taken out of the battery package in which the button battery was placed, if the battery is left unattended without replacement, or if the child breaks the blister package by himself, the child may misunderstand the battery. Swallow button batteries. In addition, if the button battery is swallowed by mistake, alkaline liquid is generated from the but...
