DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an envelope clip, and more particularly to an envelope clip, which can be attached to an opening of an envelope to prevent heavy objects such as coins from falling from the inside of the envelope without bonding a cover piece of the envelope. It relates to a possible envelope clip.

[0002]

2. Description of the Related Art Envelopes of various sizes and shapes are commercially available depending on the application, but after inserting the contents as in the case of mailing, the lid at the opening is sealed and sealed. Various types of envelopes are also used, for example, for monthly tuition at study schools, training schools for cooking and ikebana, and for storing collected money.

[0003] In particular, envelopes used for monthly fees and collections, such as the latter, are often used repeatedly. Therefore, after the money is stored in the envelope, the money inside the envelope can be removed without adhesively sealing the lid of the envelope. In order to prevent sneaking out, a measure has been taken in which an envelope lid piece is sandwiched and closed with a metal clip such as a pair of zem clips or spring clips and stored in a bag or the like.

[0004]

However, in recent years, a large amount of coins are often stored in the envelope with the addition of the consumption tax. Therefore, the opening of the envelope is temporarily closed with a metal clip as described above. Even if it is stopped, the metal clip is slippery, so if external force acts on the metal clip in the mobile bag or the moving gravity of the coin acts on it,
As the metal clip is gradually pushed outward, the metal clip comes off from the opening of the envelope, and a coin may come out of the envelope.

[0005] Such a disadvantage can be solved by using an openable and closable envelope in which the opening of the envelope is closed with a cord, but this kind of envelope is expensive and
Damage to a portion of the envelope is significantly uneconomical, as a new purchase must be made.

The present invention provides an envelope clip which can be easily attached to the opening of a commercially available inexpensive paper envelope, and which can reliably maintain the closed state of the opening without gluing the opening of the envelope. It was made for the purpose of providing.

[0007]

SUMMARY OF THE INVENTION The present invention comprises a base member which can open and close an envelope clip, and a holding member, and is provided between an opening end portion of the envelope and a cover piece folded back on the base member side. The tongue inserted into the tongue is provided so that the leading edge of the tongue locks the folded portion of the lid of the envelope, and the open end of the envelope located on the upper surface of the tongue is engaged with the upper surface of the tongue and the pressing member. The above-mentioned problem has been solved by being sandwiched by a sandwiching portion constituted by a lower surface.

That is, in the envelope clip of the present invention, a horizontally-long rectangular base member and a holding member are connected to each other at one edge thereof via a thin hinge portion so as to be openable and closable, and are provided on an upper surface side of the base member. A tongue that can be inserted between an opening end of the envelope and a lid piece of the envelope formed by folding back from the opening end is provided, and the lower surface of the pressing member and the tongue piece facing the lower surface are provided. The upper surface forms a holding portion for holding the opening end of the envelope in a closed state where the holding member is overlapped with the base member, and furthermore, the holding member is attached to the base member on the thin hinge side of the base member and the holding member. It is characterized in that disengageable locking means for maintaining the overlapping closed state is provided.

The base member and the holding member of the envelope clip are integrally formed with a molding material such as a synthetic resin together with a thin hinge portion which connects these members so that they can be opened and closed. The size is determined in accordance with the width of the opening of the envelope, and the whole is formed in a horizontally long rectangular shape so that it can be attached to the opening of the envelope in a good manner.

[0010] The tongue piece provided integrally with the base member of the envelope clip is connected to the base via the other end edge of the base member, that is, the end edge opposite to the thin hinge portion through a continuous arc-shaped connecting portion. Although it may be extended along the upper surface of the member, a receiving low wall which protrudes upward from the other end of the base member is formed, and extends along the upper surface of the base member from the upper end of the center of the receiving low wall. You may. The extension length of the tongue piece may be substantially the same as the folded width of the envelope lid piece, and the width of the tongue piece may be slightly smaller than the length of the envelope lid piece. Further, by forming the receiving low wall on the upper surface of the other end of the base member, even if the folded width of the lid of the envelope is larger than the extension length of the tongue, the tip of the lid of the envelope can be formed. This is preferable because the portion abuts against the receiving low wall and is received, and the envelope can be supported in a stable state.

In a closed state in which the pressing member is superimposed on the base member, the holding portion for holding the opening end of the envelope formed by the upper surface of the tongue piece and the lower surface of the pressing member opposed to the upper surface has a reliable shape. In order to obtain a clamping force, several parallel ridges are formed on the upper surface of the tongue piece of the base member, and the upper surface of the tongue piece in the closed state where the pressing member is overlapped on the base member is also formed on the lower surface of the pressing member. It is preferable to form a ridge located between the ridges. Adhering an elastic sheet piece such as a rubber sheet or a sponge sheet to the upper surface of the tongue piece or the lower surface of the pressing member or both instead of the above-mentioned ridges is also a preferable means for obtaining a reliable clamping force. .

The structure of the detachable locking means for holding the holding member in a closed state in which the holding member is superimposed on the base member, that is, the closed state of the envelope opening, is not particularly limited. Hook-shaped projections (female members) are formed on the upper surface of the base member at left and right intervals along the thin hinge portion, and the hooks are formed on the lower surface of the holding member at right and left intervals along the thin hinge side. A hook-shaped protruding piece (male member) capable of engaging with the projection is provided upright, and when the pressing member is superimposed on the base member, the female member and the male member are engaged with each other to ensure a closed state. It is preferable to employ locking means that can easily be disengaged when an opening operation force is applied to the member.

Further, by forming a through hole in one or both of the base member and the holding member of the envelope clip, the weight of the envelope clip can be reduced. When this through hole is formed in the base member, a window hole may be formed in a portion of the base member facing the lower surface of the tongue piece. This not only makes it possible to confirm that the envelope has been clipped properly, but also if the identification letter is written on the portion of the surface of the envelope lid that corresponds to the window hole when the envelope clip is attached, the identification can be made through the window hole. It is preferable because characters can be recognized.

[0014]

According to the present invention, the base member of the envelope clip of the present invention has a tongue extending from the open end of the envelope and the lid of the envelope folded back from the open end. In a state where the opening of the envelope is sealed with the envelope clip,
The folded portion of the lid of the envelope is locked by the leading edge of the tongue, and the opening of the envelope is held by the holding portion formed by the upper surface of the tongue and the lower surface of the pressing member facing the upper surface.
