Abstract

PURPOSE:To obtain a reusable tape, by providing the substrate of an adhesive tape, coated with a non-drying adhesive, with a portion not coated with said adhesive, so that when the tape is released, the non-coated portion is folded onto the adhesive surface so as to prevent the adhesive from weathering and dust from adhering ont the adhesive. CONSTITUTION:A tape substrate 1 having a surface portion 1a on which a non- drying adhesive 2 is applied with the remaining surface portion left as a guard tape 3 to obtain the titled adhesive tape. When this adhesive tape is detached after it has adhered once, by folding the tape guard 3 onto the adhesive surface, dust is prevented from adhering onto the adhesive surface, and the adhesive is prevented from weathering, so that the tape can be repeatedly used. It is preferred to apply a release agent on the surface of the guard tape 3. Further, if this tape is applied as a double-side adhesive tape onto a foldable lid portion of a synthetic resin film bag, the respective guard tapes can be temporarily stuck to the corresponding adhesive surfaces when the lid is open, so that the contents can be introduced into or removed from the bag without adhering to the adhesive, and the resealing can easily be done.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous guard adhesive tape, and the conventional adhesive tape is a basic tape coated with a non-drying adhesive on one or both sides, and the long tape is coated with a single-sided adhesive. The coated tape is wrapped around the core material 5 times, and the double-sided adhesive coated tape is wrapped with a separate release tape, and in the case of regular length short tape, a separate release tape is attached. (1) is temporarily attached to the surface where the agent is applied, and when used, the former long tape is applied directly to the area where it will be applied, while the tape is rolled back up, while the latter short tape is one-sided adhesive. In the case of adhesive-coated tape, the back side of the basic tape is heat-adhered to the application area, or the release paper on the front is peeled off and the adhesive side is applied to the application area, and the release paper is used. Usually, it is discarded as soon as it is peeled off, and if the surface to which it is attached is made of synthetic resin, polished metal, or a surface that can be peeled and stuck, such as ceramic or glass, it may be pasted and peeled a considerable number of times. However, in the case of peeled objects, the adhesive-applied surface often adheres to other objects unwillingly, causing various difficulties, and the peeling period may be prolonged. It is normal for the adhesive on the adhesive surface to weather, or for dust to adhere to the adhesive, resulting in a markedly poor adhesive strength and the adhesive tape becoming unable to be attached or removed. be.

The present invention has been developed in view of the above-mentioned conventional inconveniences, and for example, the above-mentioned adhesive (2) tape is often used for the folding of synthetic resin film bags or the folding parts of the bags. However, until the adhesive tape is applied to the bag, it may be protected by release paper, but the release paper on the adhesive-applied side can be peeled off with a pair of scissors, and the opening of the bag can be bonded to the lid and bag. When removing items from the bag by peeling them off, the adhesive surface may accidentally stick to the items or hands, making it extremely difficult to apply the adhesive. In some cases, resealing becomes difficult due to weak adhesive strength.

The present invention will be described in detail with reference to the drawings. The drawings show a short adhesive tape of a fixed length made of synthetic resin, and as shown in the developed perspective view of Fig. 1, one side (la) of the tape is non-drying. The basic tape (1) coated with adhesive (2) is placed below the guard tape (3) which extends slightly larger than the surface (la) coated with non-drying adhesive (2). It is folded back from the fold line (4) provided at the boundary between (1a) and the extended tape (3) and temporarily attached to the adhesive coated surface (1a) to constitute an example of the guard continuous adhesive tape of the present invention. ing. In addition, the basic tape (
1) can be used in various ways by extending the guard tape upward, downward, both above and below, or sideways, both sides, etc., and the basic tape (1) is In the case of paper, cloth, etc., the same effect can be obtained by coating or impregnating the guard tape (3) with a release agent.

The installation of the cart-connecting adhesive tape of the present invention at the point where it is used is similar to the conventional adhesive tape in which a separate release paper is attached to the adhesive-coated surface, and the adhesive-coated surface is still attached to the other side. The same process is used when attaching the tape to the attachment point, such as peeling off the guard tape (3) and attaching the adhesive side to the other attachment point, but the most different and important issues are as follows. However, the main difference is that the release paper that was attached to the conventional adhesive-coated side is a separate piece of release paper that is peeled off when attaching the adhesive-coated side of the adhesive tape to the other party's attachment point. Since it is not possible to reuse the stored items because they are thrown away and cannot be reused, as mentioned above, when taking out the stored items, you may inadvertently apply unguarded adhesive tape to some of the stored items or your hands. Although the adhesive side may adhere to the adhesive side, causing a serious inconvenience or significantly reducing the adhesive effect of the adhesive-coated side, the continuous guard adhesive tape of the present invention has an adhesive-coated side (1a). Even if the guard tape (3) is peeled off when applying the tape to the application area of the other party, the guard tape (3) is an extension of the basic tape (1), so it remains in the form of an extension of the basic tape (1). Because of this, the pieces of tape exist very close together without getting in the way, so when you need to take out stored items, fold the guard tape (3) back from the fold line (4) and use the basic tape ( Guard tape (3) can be temporarily attached to the non-drying adhesive (2) on the adhesive application side (la) of 1) with one touch or by folding naturally from the fold line (4). Therefore, the adhesive-applied surface (1a) cannot be directly touched by stored items or hands, so it is possible to take in and take out stored items extremely smoothly, and the adhesive (2) is guarded so that it cannot be touched. Also, there is no adhesion of surrounding dust, etc., and the adhesive (2) also prevents weathering of itself and the body, thereby preventing the decline in adhesive strength and maintaining adhesive strength for a longer period of time than ordinary adhesive tapes. This is a highly valuable one-guard continuous adhesive tape that you can own.
