Description

Technical Field

[0001] This utility model belongs to the field of bottle cap technology, specifically, it relates to a deoxidizing bottle cap for edible oils. Background Technology

[0002] In the structure of bottled water, bottled condiments, bottled oil, etc., the bottle cap mainly serves a sealing function. In addition to sealing, giving the bottle cap a storage function can increase its practicality.

[0003] The main cause of food spoilage is bacterial growth due to moisture absorption and oxidation by oxygen in the air. Take cooking oil as an example: oils oxidize and spoil when exposed to oxygen for extended periods. Cooking oil is usually bottled, sealed, and then sold. Repeated opening of the bottle cap during storage and use inevitably exposes the oil to oxygen, leading to oxidation. Not only cooking oil, but other types of oil also suffer from oxidation upon contact with air. Antioxidants or oxygen absorbers are effective at preventing oxidation. Currently, in the preservation of solid foods, it is widely used to seal oxygen absorbers in breathable bags along with the solid food, and its safety is well-assured. However, for liquids like cooking oil, there are no effective antioxidants. Summary of the Invention

[0004] In view of the problems existing in the background technology, if liquid materials (taking edible oil as an example) come into direct contact with deoxidizers like solid foods, not only can safety not be guaranteed, but also, in bottled edible oil, the main oxidation of edible oil is the air between the bottle cap and the oil surface. Therefore, removing the oxygen in the air between the bottle cap and the oil surface is feasible in preventing oil oxidation. In view of this, this utility model proposes an edible oil deoxidizing bottle cap. Through structural design, the bottle cap can store deoxidizers, which absorb oxygen in the oil bottle, thereby playing an antioxidant role.

[0005] To achieve the above objectives, this utility model is implemented through the following solution:

[0006] The aforementioned edible oil deoxidizing bottle cap includes a storage cylinder, a deoxidizing agent, and a deoxidizing agent blocking component; the deoxidizing agent is placed inside the storage cylinder; the deoxidizing agent blocking component is located at the lower end of the storage cylinder; the upper port of the storage cylinder is sealed; and a bottle cap ring is provided outside the storage cylinder.

[0007] Furthermore, the deoxidizer blocking component is a baffle plate disposed in the lower inner cavity of the storage cylinder; a gas passage is maintained between the baffle plate and the cylinder wall of the storage cylinder; the deoxidizer is placed above the baffle plate; and the deoxidizer is a bagged deoxidizer.

[0008] Furthermore, the baffle is fixed to the inner cavity of the storage cylinder in a straight line, cross shape, star shape, or strip shape.

[0009] Furthermore, an inverted conical step is provided between the outer wall of the storage cylinder and the inner wall of the bottle cap ring.

[0010] Furthermore, the deoxidizer blocking component also includes a food-permeable membrane sealed at the lower port of the storage cylinder.

[0011] Furthermore, the baffle is fixed to the inner cavity of the storage cylinder in a straight line, cross shape, star shape, or strip shape.

[0012] Furthermore, the deoxidizer blocking component is a food-grade breathable membrane; the food-grade breathable membrane is sealed at the lower port of the storage cylinder.

[0013] Furthermore, an inverted conical step is provided between the outer wall of the storage cylinder and the inner wall of the bottle cap ring.

[0014] Furthermore, the bottle cap ring is located at the lower part of the storage cylinder; the lower end of the storage cylinder is longer than, flush with, or shorter than the bottle cap ring; and the lower end of the bottle cap ring is provided with an anti-theft ring.

[0015] Furthermore, the upper port of the storage cylinder is sealed with a sealing film, and a bottle cap is placed over the upper port.

[0016] Furthermore, the upper part of the storage cylinder is provided with external threads; the bottle cap is connected to the storage cylinder by a threaded connection.

[0017] Furthermore, the inner wall of the decorative bottle cap and the outer wall of the storage container are provided with a locking structure.

[0018] The beneficial effects of this utility model are:

[0019] This invention, through the structural design of the storage cylinder and the deoxidizer blocking component at the lower end of the storage cylinder, enables the deoxidizer to be placed inside the storage cylinder under the support of the deoxidizer blocking component, thereby removing oxygen without contacting the material inside the bottle and achieving an anti-oxidation effect on liquid oils.

[0020] The deoxidizer blocking structure at the lower port and the sealing structure at the upper port of the storage cylinder of this utility model can keep the deoxidizer isolated from the outside air, and only adsorb oxygen inside the bottle, thereby achieving the adsorption of oxygen inside the bottle without affecting the seal of the bottle mouth.

[0021] The structure of this utility model features a sealing film and a bottle cap on the upper part of the storage cylinder, which can be sealed and closed after the deoxidizer is placed. It is easy to process, has a good sealing effect, and the bottle cap can protect the sealing film.

[0022] This invention uses a simple structure to achieve non-contact storage of deoxidizers and liquid materials such as edible oils, ensuring food safety while preventing food oxidation. Attached Figure Description

[0032] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0033] In the description of this utility model, unless otherwise stated, the terms "upper" and "lower" indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Note: For ease of description, the structure of this utility model is illustrated using the example of a cap fitting onto an edible oil bottle. However, it should be noted that the application of this utility model is not limited to edible oil bottles; the cap of this utility model is applicable to any bottle that requires deoxygenation.

[0036] like Figure 1-8 As shown, the deoxidizing cap for edible oils includes a storage cylinder 1, a deoxidizing agent 2, and a deoxidizing agent blocking component.

[0037] The storage cylinder 1 is provided with a bottle cap ring 3 that is sealed to its outer wall. The main function of the bottle cap ring 3 is to seal the bottle opening. As a preferred embodiment, the lower end of the bottle cap ring 3 is provided with an anti-theft ring 7.

[0038] As a preferred embodiment, an inverted conical step 6 is provided between the outer wall of the storage cylinder 1 and the inner wall of the bottle cap ring 3. When the present invention is closed on the mouth of the oil bottle, the inverted conical step 6 can widen the mouth of the oil bottle and enhance the sealing effect of the oil bottle mouth.

[0039] The deoxidizer 2 is placed in the storage cylinder 1. The deoxidizer 2 is a bagged deoxidizer, which can be a commercially available finished bagged deoxidizer. The bag of the commercially available bagged deoxidizer is a breathable bag. Under the obstruction of the deoxidizer blocking component of this utility model, the bagged deoxidizer is not easy to fall into the bottle.

[0040] A deoxidizer blocking component is provided at the lower end of the storage cylinder 1. The deoxidizer blocking component provides a ventilable seal for the storage cylinder 1. The ventilable seal means that after sealing, gas can pass through, but the deoxidizer will not fall into the bottle from the deoxidizer blocking component. Any structure that can achieve this function can be used as the "deoxidizer blocking component" of this utility model. Three structural examples are listed below:

[0041] Method 1: Install a food-permeable membrane 5 (as shown in the attached image) at the lower port of the storage cylinder 1. Figure 3 The food-grade breathable membrane 5 is made of existing materials; any food-grade sealing membrane with breathable, or breathable, hydrophobic, or oleophobic functions can be used, such as PP food-grade sealing membrane. The second method involves installing a baffle 4 (as shown in the attached image) in the lower inner cavity of the storage cylinder 1. Figure 6 and attached Figure 7 It is necessary to ensure that a gas passage is maintained between the baffle 4 and the wall of the storage cylinder 1. The deoxidizer 2 is placed above the baffle 4. The baffle can be made of PP material. The baffle 4 is fixed to the inner wall of the storage cylinder 1 and can be straight, cross-shaped, star-shaped, or strip-shaped (as shown in the attached diagram). Figure 8 Any structure that can both prevent the deoxidizer from falling into the bottle and retain a gas passage. Third type: A food-permeable membrane 5 is installed at the lower end of the storage cylinder 1, and a baffle 4 (as shown in the attached image) is installed inside the storage cylinder 1 and above the food-permeable membrane 5. Figure 5 ).

[0042] In the second and third structures described above, the height of the baffle 4 inside the storage cylinder 1 is adjusted according to the usage to simultaneously meet the following requirements: 1) ensure sufficient space for the deoxidizer to be stored, and 2) prevent it from contacting the liquid inside the bottle.

[0043] The main function of the storage cylinder 1 of this utility model is to store the deoxidizer 2, while isolating the upper end of the deoxidizer 2 from external air and sealing the lower end for air permeability. Any cylinder structure that can achieve this function is acceptable. Several structures that can achieve this function are listed and exemplified below:

[0044] The first type, storage cylinder 1, has a straight cylindrical structure (as shown in the attached image). Figure 7 The bottle cap ring 3 is located at the lower part of the storage cylinder 1. The lower end of the storage cylinder 1 can be longer than the bottle cap ring 3, shorter than the bottle cap ring 3, or flush with the bottle cap ring 3.

[0045] The second type has a stepped, tapering structure (as shown in the attached image). Storage cylinder 1 has a wider top and narrower bottom. Figure 3 , 5 6) The bottle cap ring 3 is still set at the lower end of the storage cylinder 1. The upper diameter of the storage cylinder 1 can be adjusted according to the volume of deoxidizer to be contained, or it can be adjusted from an aesthetic point of view. The lower end of the storage cylinder 1 can be longer than the bottle cap ring 3, shorter than the bottle cap ring 3, or flush with the bottle cap ring.

[0046] As a preferred embodiment, when the lower end of the storage cylinder 1 is shorter than the cap ring 3, the deoxidizer blocking component preferably has the first or third structure described above (only the baffle 4 is provided, or both the baffle 4 and the food breathable membrane 5 are provided); when the lower end of the storage cylinder 1 is longer than the cap ring 3, the deoxidizer blocking component preferably has the second structure described above (only the food breathable membrane 5 is provided).

[0047] The upper port of the storage cylinder 1 is airtight. By sealing the upper port, the cylinder is isolated from the outside air after the cap is placed on the bottle opening. Any airtight sealing structure is acceptable. This embodiment lists several structures that can achieve this function, and specific examples are as follows:

[0048] The first method is to seal the upper port of the storage cylinder 1 with a sealing film 8 (such as a non-breathable sealing film like food-grade aluminum film).

[0049] The second method involves sealing the upper end of the storage cylinder 1 with a sealing film 8, and then covering it with a bottle cap 9. Specifically, an external thread 10 is provided on the upper part of the storage cylinder 1, and an internal thread matching the external thread 10 is opened on the inner wall of the bottle cap 9. The bottle cap 9 and the storage cylinder 1 are sealed together by a threaded connection.

[0050] The third method involves providing an external thread 10 on the upper part of the storage cylinder 1 and opening an internal thread on the inner wall of the bottle cap 9 that matches the external thread 10, thereby sealing the bottle cap 9 and the storage cylinder 1 together through a threaded connection.

[0051] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
